Description

Technical Field

[0001] This utility model relates to the field of mobile device accessories technology, and in particular to a split-type mobile power supply. Background Technology

[0002] Portable power banks, also known as power banks, are designed to provide temporary power to other electronic devices. With the widespread use of mobile devices such as smartphones, tablets, and wearable devices, portable power banks have become an essential accessory in daily life. Currently, a single portable power bank can only charge one mobile device at a time, and cannot charge multiple mobile devices simultaneously. Although there are portable power banks on the market with multiple charging ports, connecting to multiple mobile devices via multiple charging cables to achieve simultaneous charging, the movement space of each mobile device is limited. That is, the mobile devices cannot be too far apart during charging, resulting in low flexibility in charging multiple mobile devices.

[0003] It should be noted that the above content is only used to help understand the technical solution of this utility model, and does not represent an admission that the above content is prior art. Utility Model Content

[0004] The main purpose of this invention is to propose a split-type mobile power supply, which aims to enable simultaneous charging of multiple mobile devices, and to improve the flexibility of charging multiple mobile devices without being affected by the distance between them during the charging process.

[0005] To achieve the above objectives, this utility model proposes a split-type portable power bank;

[0006] Specifically, the split-type portable power bank includes:

[0007] A first housing, wherein a first power module is disposed inside the first housing; an insertion cavity is disposed on a first side of the first housing, wherein a first electrical connector is disposed inside the insertion cavity; and a first charging interface is disposed on a second side of the first housing, wherein the first charging interface is electrically connected to the first power module.

[0008] A second housing, inside which a second power module is disposed; an insert is disposed on the side of the second housing, the insert engaging with the insertion cavity to allow the first housing and the second housing to be detachably connected; the insert is provided with a second electrical connector, the second electrical connector being electrically connected to the first electrical connector to allow the first power module and the second power module to be electrically connected; the second housing is provided with a second charging interface, the second charging interface being electrically connected to the second power module.

[0009] In one embodiment, the split-type portable power supply further includes a power transmission interface, which is disposed in the first housing or the second housing; when the second electrical connector is electrically connected to the first electrical connector, the power transmission interface receives electrical energy from an external power source and transmits it to the first power module and the second power module.

[0010] In one embodiment, the second charging interface is disposed at the free end of the insert, and when the insert is plugged into the insertion cavity, the second charging interface is housed inside the insertion cavity.

[0011] In one embodiment, a foolproof component is provided between the insert and the insertion cavity. The foolproof component includes a foolproof groove disposed in the insert and a foolproof block disposed in the insertion cavity. The foolproof block is inserted into the foolproof groove.

[0012] In one embodiment, a first magnet is provided on the inner wall of the insertion cavity, and a second magnet is provided on the free end of the insert, wherein the first magnet and the second magnet are magnetically attracted to each other.

[0013] In one embodiment, the insert is provided with two second magnets, which are symmetrically arranged on opposite sides of the free end of the insert.

[0014] In one embodiment, the second housing is provided with a separation component, which is used to overcome the magnetic attraction between the first magnet and the second magnet to separate the first housing from the second housing.

[0015] In one embodiment, the separating assembly includes a first rod and a second rod arranged perpendicularly to each other. The interior of the second housing is provided with a first sliding groove and a second sliding groove. The first rod is slidably connected to the first sliding groove, and the second rod is slidably connected to the second sliding groove. A first end of the first rod protrudes outside the first sliding groove, and a second end of the first rod has a protrusion. A recess is provided on the side of the second rod, and an inclined mating surface is provided between the protrusion and the recess. When the first rod moves towards the second rod, so that the protrusion engages with the recess along the inclined surface, the second rod slides along the second sliding groove, so that the end of the second rod extends out of the insert and abuts against the inner wall of the insertion cavity.

[0016] In one embodiment, the first sliding groove is provided with a first reset cavity; the first rod is fixedly sleeved with a first limiting ring, and the first rod is movably sleeved with a first spring member, the two ends of the first spring member respectively abutting the first reset cavity and the first limiting ring; and / or, the second sliding groove is provided with a second reset cavity; the second rod is fixedly sleeved with a second limiting ring, and the second rod is movably sleeved with a second spring member, the two ends of the second spring member respectively abutting the second reset cavity and the second limiting ring.

[0017] In one embodiment, the separation components are provided in two sets, and the two sets of separation components are symmetrically arranged on opposite sides of the second housing.

[0018] The technical solution of this utility model involves setting up a detachable first housing and a second housing. The first housing is provided with a first charging interface and a first power module that are electrically connected to each other, and the second housing is provided with a second charging interface and a second power module that are electrically connected to each other. Thus, the first housing and the second housing can be regarded as independent mobile power supply units. When multiple mobile devices need to be charged simultaneously, by separating the first housing and the second housing, each housing can charge a single mobile device individually. In this case, the distance between each mobile device is not affected during the charging operation, which improves the flexibility of charging multiple mobile devices. When only a single mobile device needs to be charged, the first housing and the second housing can be combined and installed using an insert and an insertion cavity. In this case, the first electrical connector and the second electrical connector are electrically connected to each other, allowing the first power module and the second power module to transfer electrical energy to each other to form a high-capacity battery module, ensuring sufficient power to charge a single mobile device.

[0031] In existing technologies, a single power bank can only charge a single mobile device, and cannot charge multiple mobile devices simultaneously. Although there are power banks on the market with multiple charging ports that connect to multiple mobile devices via multiple charging cables to charge multiple devices simultaneously, the movement space of each mobile device is limited. That is, the mobile devices cannot be too far apart during the charging process, resulting in low flexibility in charging multiple mobile devices.

[0032] To solve the above-mentioned technical problems, this utility model proposes a split-type mobile power supply.

[0033] Please see Figures 1 to 3 In this embodiment, the split-type portable power bank includes:

[0034] A first housing 100 is provided inside the first housing 100, and a first power module (not shown in the figure) is provided inside the first housing 100; an insertion cavity 200 is provided on the first side of the first housing 100, and a first electrical connector (not shown in the figure) is provided inside the insertion cavity 200; a first charging interface 110 is provided on the second side of the first housing 100, and the first charging interface 110 is electrically connected to the first power module.

[0035] A second housing 300 is provided inside which a second power module (not shown in the attached drawings) is disposed. An insert 400 is provided on the side of the second housing 300, which is inserted into the insertion cavity 200 to allow the first housing 100 and the second housing 300 to be detachably connected. The insert 400 is provided with a second electrical connector 410, which is electrically connected to the first electrical connector to allow the first power module and the second power module to be electrically connected. The second housing 300 is provided with a second charging interface 310, which is electrically connected to the second power module.

[0036] The technical solution of this embodiment provides a detachable first housing 100 and a second housing 300. The first housing 100 is provided with a first charging port 110 and a first power module that are electrically connected to each other, and the second housing 300 is provided with a second charging port 310 and a second power module that are electrically connected to each other. Thus, the first housing 100 and the second housing 300 can be regarded as independent mobile power supply units. When multiple mobile devices need to be charged simultaneously, the first housing 100 and the second housing 300 are separated, and the user can then connect a charging cable to the first charging port 110 of the first housing 100 or the second charging port 310 of the second housing 300 respectively.

[0037] This allows the first housing 100 and the second housing 300 to charge a single mobile device independently. During charging, the distance between each mobile device is not a factor, improving the flexibility of charging multiple mobile devices. When only a single mobile device needs charging, the first housing 100 and the second housing 300 can be assembled using the insert 400 and the insertion cavity 200. In this case, the first and second electrical connectors 410 are electrically connected, allowing the first and second power modules to transfer power to each other to form a high-capacity battery module, ensuring sufficient power to charge the single mobile device.

[0038] The first charging interface 110 and the second charging interface 310 are interfaces used to output the electrical energy stored inside the power bank to external devices (such as smartphones, tablets, laptops, etc.). Their main function is to transfer electrical energy from the power bank to the external device that needs charging. In this embodiment, both the first charging interface 110 and the second charging interface 310 are configured as USB interfaces.

[0039] The first and second electrical connectors 410 are electrically connected, allowing the first and second power modules to transfer electrical energy to form a high-capacity battery module, ensuring smooth charging and power transmission operations of the power bank. In this embodiment, both the first and second electrical connectors 410 are made of highly conductive copper alloy with gold plating to improve oxidation resistance and conductivity. They are designed with multi-point contact to ensure rapid and accurate contact between the first and second electrical connectors 410 during insertion of the insert 400 into the insertion cavity 200, forming a stable electrical connection. Both the first and second electrical connectors 410 are equipped with overcurrent protection devices to prevent equipment damage due to abnormal conditions during the electrical connection process.

[0040] Furthermore, the split-type power bank also includes a power transmission interface 120, which is disposed on the first housing 100 or the second housing 300. When the second electrical connector 410 is electrically connected to the first electrical connector, the power transmission interface 120 receives electrical energy from an external power source and transmits it to the first power module and the second power module. With this configuration, this embodiment only provides a single power transmission interface 120. When it is necessary to replenish the first power module and the second power module, the first housing 100 and the second housing 300 are combined and installed so that the first electrical connector and the second electrical connector 410 are electrically connected to each other, thereby enabling the first power module and the second power module to transmit electrical energy to each other. In addition, providing only a single power transmission interface 120 also saves manufacturing costs, as it eliminates the need to separately provide power transmission interfaces 120 on the first housing 100 and the second housing 300 to separately transmit power to the first power module and the second power module. In this embodiment, the power transmission interface 120 is disposed on the second side of the first housing 100.

[0041] The power transmission interface 120 is an interface used to charge the battery module (such as the first power module or the second power module) inside the power bank from an external power source (such as a power adapter, USB power supply, car charger, etc.). Its main function is to receive electrical energy provided by the external power source and transmit it to the battery module of the power bank for storage. In this embodiment, the power transmission interface 120 is set as a Type-C interface.

[0042] As a preferred embodiment of the above embodiments, refer to Figures 1 to 3 The second charging interface 310 is located at the free end of the insert 400. When the insert 400 is engaged with the insertion cavity 200, the second charging interface 310 is housed inside the insertion cavity 200. This arrangement, with the second charging interface 310 located at the free end of the insert 400 and housed inside the insertion cavity 200, hides the second charging interface 310 in the assembled state. This prevents external dust and debris from entering, improving the durability and reliability of the interface. Furthermore, when only a single mobile device needs to be charged, the user can accurately locate the first charging interface 110 and avoid accidentally inserting the second charging interface 310.

[0043] As a preferred embodiment of the above embodiments, refer to Figures 1 to 3A foolproof component 600 is provided between the insert 400 and the insertion cavity 200. The foolproof component 600 includes a foolproof groove 620 disposed in the insert 400 and a foolproof block 610 disposed in the insertion cavity 200. The foolproof block 610 and the foolproof groove 620 are engaged. This arrangement ensures that the insert 400 can only be inserted into the insertion cavity 200 in the correct manner, avoiding poor electrical connection or damage between the first electrical connector and the second electrical connector 410 due to incorrect insertion.

[0044] As a preferred embodiment of the above embodiments, refer to Figures 1 to 3 A first magnet (not shown in the attached diagram) is provided on the inner wall of the insertion cavity 200, and a second magnet 420 is provided on the free end of the insert 400. The first magnet and the second magnet 420 are magnetically attracted to each other. This arrangement ensures that the magnetic attraction between the first magnet and the second magnet 420 guarantees a tight connection between the insert 400 and the insertion cavity 200 when they are joined, thus ensuring a more stable electrical connection between the first electrical connector and the second electrical connector 410 and avoiding charging problems caused by poor contact. Simultaneously, the magnetic force guides the insert 400 to accurately insert into the insertion cavity 200, improving user convenience and efficiency.

[0045] Furthermore, the insert 400 is provided with two second magnets 420, which are symmetrically arranged on opposite sides of the free end of the insert 400. This arrangement allows the symmetrically arranged second magnets 420 to provide a more uniform magnetic attraction force, further enhancing the connection stability between the insert 400 and the insertion cavity 200 and ensuring the reliability of the electrical connection.

[0046] As a preferred embodiment of the above embodiments, the second housing 300 is provided with a separation component 500. The separation component 500 is used to overcome the magnetic attraction between the first magnet and the second magnet 420, so as to separate the first housing 100 and the second housing 300 from each other. With this configuration, the separation component 500 can overcome the magnetic attraction, making it convenient for the user to separate the first housing 100 and the second housing 300 from the combined state, avoiding separation difficulties caused by excessive magnetic attraction.

[0047] There are many specific structures for the separation component 500. In this embodiment, refer to... Figures 4 to 5The separation assembly 500 includes a first rod 510 and a second rod 520 arranged perpendicularly to each other. The interior of the second housing 300 is provided with a first sliding groove 530 and a second sliding groove 540. The first rod 510 is slidably connected in the first sliding groove 530, and the second rod 520 is slidably connected in the second sliding groove 540. The first end of the first rod 510 is exposed outside the first sliding groove 530, and the second end of the first rod 510 is provided with a protrusion 511. The side of the second rod 520 is provided with a recess 521, and there is an inclined mating surface 550 between the protrusion 511 and the recess 521. When the first rod 510 moves towards the second rod 520 so that the protrusion 511 is engaged with the recess 521 along the mating surface 550, the second rod 520 slides along the second sliding groove 540 so that the end of the second rod 520 extends out of the insert 400 and abuts against the inner wall of the insertion cavity 200. With this configuration, since the first end of the first rod 510 is exposed outside the first sliding groove 530, the user can press the first end of the first rod 510 to move the first rod 510 along the first sliding groove 530 toward the second rod 520. At this time, the protrusion 511 at the second end of the first rod 510 is engaged with the recess 521 along the mating slope 550. Since the mating slope 550 is inclined, under the influence of action and reaction forces, the second rod 520 is driven to slide along the second sliding groove 540, so that the end of the second rod 520 is gradually exposed outside the second sliding groove 540, and finally extends out of the insert 400 and abuts against the inner wall of the insertion cavity 200, so that the insert 400 and the insertion cavity 200 are separated from each other. This achieves the purpose of overcoming the magnetic attraction of the third magnet and the fourth magnet to separate the first housing 100 and the second housing 300 from each other.

[0048] Furthermore, the first sliding groove 530 is provided with a first reset cavity 531; the first rod 510 is fixedly sleeved with a first limiting ring 512, and the first rod 510 is movably sleeved with a first spring member 513, the two ends of the first spring member 513 respectively abutting against the first reset cavity 531 and the first limiting ring 512; and / or, the second sliding groove 540 is provided with a second reset cavity 541; the second rod 520 is fixedly sleeved with a second limiting ring 522, and the second rod 520 is movably sleeved with a second spring member 523, the two ends of the second spring member 523 respectively abutting against the second reset cavity 541 and the second limiting ring 522. With this configuration, the first spring member 513 and the second spring member 523 can achieve automatic reset of the first rod 510 and the second rod 520, allowing the separation assembly 500 to automatically return to its initial state after use, facilitating the next use. Understandably, during the process of the user applying pressure to drive the first rod 510 and the second rod 520 to slide, as shown in the attached... Figure 5As shown, the first limiting ring 512 of the first rod 510 combines with the first reset cavity 531 to compress the first spring member 513; similarly, the second limiting ring 522 of the second rod 520 combines with the second reset cavity 541 to compress the second spring member 523; when the first housing 100 and the second housing 300 separate, and the user releases the pressing pressure applied to the first rod 510, as shown in the attached diagram... Figure 4 As shown, the first spring 513 and the second spring 523 are elastically applied to reset the first rod 510 and the second rod 520.

[0049] Furthermore, two sets of separation components 500 are provided, symmetrically arranged on opposite sides of the second housing 300. This arrangement allows the user to simultaneously operate the separation components 500 on both sides of the second housing 300, quickly overcoming the magnetic attraction between the third and fourth magnets to separate the first housing 100 and the second housing 300. This symmetrical arrangement makes the separation operation more efficient, saving the user time and effort.

[0050] It should be noted that other aspects of the split-type portable power bank disclosed in this utility model are existing technologies and will not be described in detail here.
