Description

Technical Field

[0001] This utility model relates to the field of portable electronic device technology, and in particular to a novel mobile power supply with a switchable controllable battery motherboard detachable structure. Background Technology

[0002] As safety requirements increase in outdoor work scenarios, during the long-term standby of emergency rescue lighting systems, it is necessary to completely cut off the power to the battery pack for protection, which requires the use of a portable power bank. In practical use, similar power banks still have many defects, such as: traditional power banks cannot completely cut off the standby current, which leads to safety hazards; at the same time, the frequent plugging and unplugging of traditional power banks causes interface wear and frequent accidental short circuits. Therefore, it is necessary to design a new type of power bank with a switchable control battery motherboard separation structure. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a novel mobile power supply with a switchable controllable battery motherboard detachable structure.

[0004] This utility model is achieved using the following technical solution: a novel mobile power supply with a switchable controllable battery motherboard detachable structure, comprising a protective shell, a power supply, a motherboard, a first interface, a second interface, and a detachable shell. The power supply is fixedly connected to the top inside the protective shell, and the motherboard is fixedly connected to the bottom of the power supply inside the protective shell. The output end of the power supply is provided with the first interface, and the input end of the motherboard is fixedly connected with the second interface. The detachable shell is inserted into the front end of the protective shell.

[0005] As a further improvement to the above solution, a groove is provided on the outer surface of the protective shell, and an operating slider is slidably installed inside the groove.

[0006] Through the above technical solution, the physical constraint of the linear guide mechanism improves the accuracy of user operation and reduces the risk of accidental touch, ensuring the stability and repeatability of the interface separation action.

[0007] As a further improvement to the above solution, a connecting seat is fixedly connected to the outer surface of the operating slider, and a connecting block is fixedly connected to the inside of the connecting seat.

[0008] Through the above technical solution, the modular adapter component structure design optimizes dynamic transmission efficiency and improves assembly convenience, enabling a reliable transition from sliding operation to electrical connection.

[0009] As a further improvement to the above solution, a first interface is fixedly connected to the outer surface of the connecting block, and the first interface is slidably installed inside the limiting seat.

[0010] Through the above technical solution, the geometric constraint of the track limiting system drives the parallelism control and contact impedance stabilization effect during the insertion and extraction process, ensuring the integrity of high-frequency signal transmission.

[0011] As a further improvement to the above solution, the input end of the first interface is fixedly connected to a first connecting line, and the input end of the first connecting line is fixedly connected to the output end of the power supply.

[0012] The above technical solutions, through the layout of short-path, low-loss conductors, maximize power transmission efficiency and minimize heat accumulation, thereby reducing the impact of voltage drop on equipment performance.

[0013] As a further improvement to the above solution, a second connecting line is fixedly connected to the input terminal of the motherboard, and a second interface is fixedly connected to the top of the second connecting line. The second interface is fixedly connected to the inside of the limiting seat.

[0014] As a further improvement to the above solution, a protective pad is inserted into the front end of the limiting seat, and a first interface and a second interface are slidably installed inside the protective pad.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention utilizes a linear motion structure where a slider operates within a groove, causing the first interface to slide along the trajectory of the limiting seat and dynamically connect with the second interface. Combined with the conduction and disconnection mechanism of the first and second connecting lines, it enables on-demand switching of the circuit between the power supply and the motherboard. This design allows users to physically isolate the circuit connection, ensuring complete cutoff of current transmission when not in use, achieving a zero static current state, effectively slowing down the battery self-discharge rate and extending the device's standby time. At the same time, it fundamentally eliminates the risk of overheating caused by long-term accumulation of microcurrents, significantly improving product safety and cycle life.

[0016] This invention utilizes a protective pad to buffer and wrap the interface area, thereby enhancing the connector's impact resistance and dust and water resistance. Combined with a double-layered nested protection architecture consisting of a protective shell and a detachable shell, it forms a comprehensive physical shield for the power module and circuit board. This composite protection design not only prevents damage to precision electronic components from external pressure and humidity changes, but also ensures that internal components are not easily displaced or deformed in the event of an accidental drop, maintaining the structural stability and functional reliability of the equipment in complex environments.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0020] Please combine Figure 1-5 This embodiment of a novel switchable controllable battery motherboard detachable mobile power supply includes a protective shell 1, a power supply 2, a motherboard 3, a first interface 8, a second interface 10, and a detachable shell 12. The power supply 2 is fixedly connected to the top inside the protective shell 1, and the motherboard 3 is fixedly connected to the bottom of the power supply 2 inside the protective shell 1. The output end of the power supply 2 is provided with the first interface 8, and the input end of the motherboard 3 is fixedly connected with the second interface 10. The detachable shell 12 is inserted into the front end of the protective shell 1.

[0021] The outer surface of the protective shell 1 is provided with a groove 4, and an operating slider 5 is slidably installed inside the groove 4.

[0022] A connecting seat 6 is fixedly connected to the outer surface of the operating slider 5, and a connecting block 7 is fixedly connected inside the connecting seat 6.

[0023] The outer surface of the connecting block 7 is fixedly connected to the first interface 8, which is slidably installed inside the limiting seat 14.

[0024] By pushing the operating slider 5 to slide within the groove 4, the first interface 8 is driven to slide under the limit of the limiting seat 14 under the connection of the connecting seat 6 and the connecting block 7.

[0025] The input end of the first interface 8 is fixedly connected to the first connecting line 9, and the input end of the first connecting line 9 is fixedly connected to the output end of the power supply 2.

[0026] As a further improvement to the above solution, the input terminal of the motherboard 3 is fixedly connected to a second connection line 11, the top of the second connection line 11 is fixedly connected to a second interface 10, and the second interface 10 is fixedly connected to the inside of the limiting seat 14.

[0027] The front end of the limiting seat 14 is connected to a protective pad 13, and the first interface 8 and the second interface 10 are slidably installed inside the protective pad 13.

[0028] By sliding the slider 5 in the opposite direction, it can be ensured that the power supply 2 and the motherboard 3 are in a power-off state. After the power is off, the power supply 2 stops supplying power, realizing that the power supply 2 is in a zero static current state, reducing the damage to the power supply 2 and extending the service life of the power bank.

[0029] The implementation principle of a novel switchable controllable battery motherboard detachable mobile power bank in this application embodiment is as follows: The user pushes the operating slider 5 to slide in the slide groove 4. Under the connection of the connecting seat 6 and the connecting block 7, the first interface 8 is driven to slide under the limit of the limiting seat 14. When the first interface 8 is connected to the second interface 10, the power connection between the power supply 2 and the motherboard 3 can be ensured by the first connecting line 9 and the second connecting line 11. When the operating slider 5 is slid in the opposite direction, the power supply 2 and the motherboard 3 can be ensured to be in a power-off state. After the power is off, the power supply 2 stops being powered, realizing that the power supply 2 is in a zero static current state, reducing the damage to the power supply 2, extending the service life of the power bank, and reducing the risk of spontaneous combustion of the mobile power bank when not in use. The protective pad 13 can ensure the protection of the first interface 8 and the second interface 10, and the protective shell 1 and the detachable shell 12 can ensure the protection of the power supply 2 and the motherboard 3.
