[0002] In order to meet the needs of fast charging, waterproofing and drop-proofing of mobile phones, mobile phone batteries have gradually developed into flat-wire and integrated structures. The flat-wire battery makes it complicated and delicate to disassemble or replace accessories of the mobile phone. It must be operated by professionals using professional tools. Consumers cannot replace the battery by themselves. Once the integrated battery is damaged, the mobile phone needs to be replaced, which brings great inconvenience.

[0003] At present, removable mobile phone batteries are generally of contact type structure. The battery's drop resistance and waterproof performance are poor, and poor contact is prone to occur, which affects the power supply of the mobile phone and even causes safety accidents. At the same time, when used for a long time, the poor fixation of the battery can easily lead to wear and oxidation of the contact structure, generate additional heat, increase losses, accelerate power consumption, and affect the user experience.

[0027] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0028] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0029] The battery and the mobile device are described in detail below through specific embodiments:

[0030] Reference Figures 1 to 3 As shown, some embodiments of the present invention provide a battery and a mobile device, including a battery frame 1, a cantilever 2, a connector and a contact 3.

[0031] Among them, the cantilever 2 is arranged on the side of the battery frame 1 and extends in a direction away from the battery frame 1. The cantilever 2 is detachably connected to the body 7 of the mobile device through a connector, that is, the cantilever 2 and the body 7 of the mobile device can be detachably connected through the connector, which can ensure the connection stability, prevent the contact 3 from being worn, and improve the service life. Compared with the battery of the cable type and the integrated structure, the user can remove the cantilever 2 from the body 7 by himself, and the battery can be disassembled and replaced without professional tools or professionals, which is simple to operate. The contact 3 is arranged on the cantilever 2 for contacting with the body contact on the body 7, and the area of ​​the contact 3 can be increased as needed, so that large current charging and discharging can be realized and the charging speed can be accelerated. The cantilever 2 is arranged on the body 7 of the mobile device through a connector, and the mobile device does not need to reserve the installation space 4 of the connector. In this way, the mobile device only needs to reserve a battery compartment of the size of the battery cell 6 so that the battery cell 6 can be installed in the battery compartment, which can save space and make the mobile device compact.

[0032] When implementing it, refer to Figure 2 and Figure 3 As shown, the cantilever 2 is arranged on the top of the side of the battery frame 1 and is cantilevered in a direction away from the battery frame 1. An installation space 4 for accommodating a body 7 of the mobile device is formed between the battery frame 1 and the cantilever 2.

[0033] It can be understood that when the battery is installed in a mobile device, the battery is contained in the battery compartment, the cantilever 2 is fixed to the body 7 through a connector, and the body 7 is contained in the installation space 4 between the cantilever 2 and the battery frame 1. With this arrangement, the size of the battery frame 1 can be as close as possible to the size of the battery compartment to improve the battery life of the mobile device.

[0034] Reference Figure 2 As shown, the cantilever 2 is arranged at the top of the side of the battery frame 1, that is, the top surface of the battery frame 1 is flush with the top surface of the cantilever 2, and exceeds the plane where the opening of the battery compartment is located, so that the cantilever 2 can be arranged on the top of the body 7 and fixed to the body 7 through the connecting piece. At the same time, the thickness of the cantilever 2 is relatively thin. When the cantilever 2 is arranged on the body 7, the thickness of the mobile device will not be increased, which can save space and make the mobile device structure more compact.

[0035] Reference Figure 1 As shown, the contact 3 is arranged on one side of the cantilever 2 facing the body 7 of the mobile device, so as to realize electrical contact connection with the body 7 through the contact 3 and supply power to the mobile device. Specifically, the number of the contacts 3 is at least four, including positive and negative contacts of the battery for supplying power to the mobile device, and also including an ID contact and an NTC contact for providing and identifying the temperature information of the battery to the mobile device, so as to prevent excessive current in the circuit.

[0036] Specifically, the area of ​​the contact 3 can be set according to actual needs. By increasing the area of ​​the contact 3 and the number of the contacts 3, a larger current can pass through to speed up the charging speed, thereby achieving the requirement of fast charging of mobile devices.

[0037] In some embodiments, the number of the connecting members is two, and the contact 3 is arranged between the two connecting members. Figure 1 As shown, connectors are provided on both sides of the contact 3, and the contact 3 can be electrically connected to the body 7 through the connectors. The connectors on both sides can ensure a stable contact connection between the contact 3 and the body 7 to prevent the edge of the contact 3 from warping, avoid poor contact problems, reduce power loss, and avoid generating additional heat.

[0038] Of course, it should be noted that the number of connectors can be one or three, four or more, and the present disclosure does not limit this, as long as the cantilever 2 can be fixed on the body 7 and the battery can be detachably connected to the mobile device. Specifically, the number and position distribution of the connectors can be specifically set according to actual needs.

[0039] In a specific implementation, the connecting member is a threaded fastener, and a threaded through hole 21 is provided on the cantilever 2, and the threaded fastener is inserted into the threaded through hole 21, so that the cantilever 2 is detachably connected to the body 7 of the mobile device through the threaded fastener. Figure 3 As shown, a threaded hole is opened at a position corresponding to the threaded through hole 21 on the body 7. After the threaded fastener is passed through the threaded through hole 21 on the cantilever 2, it is threadedly fastened in the threaded hole on the body 7, and then the cantilever 2 is detachably fixed to the body 7 through the connecting piece, which can ensure the contact reliability between the contact 3 and the body 7 and reduce the loss of the contact 3 structure during use.

[0040] It is understandable that the cantilever 2 is fixed to the body 7 by a threaded fastener, and the user of the mobile device can remove the threaded fastener from the body 7 by a screwdriver, and the battery can be disassembled and replaced without professional tools or professionals, making the operation simple.

[0041] It should be noted that the connecting piece can also be other structures, and the cantilever 2 can be fixed to the body 7 by other connection methods such as bonding or clamping. The present disclosure does not limit this, as long as the cantilever 2 can be detachably fixed to the body 7 to facilitate users to replace the battery by themselves, and the contact 3 can be stably connected to the body 7 to ensure stable power supply.

[0042] In specific implementation, the battery frame 1 and the cantilever 2 are plastic parts and are formed into an integrated structure by injection molding. In other words, the battery frame 1 and the cantilever 2 are an integrated structure, so that the battery cell 6 arranged in the battery frame 1 can supply power to the mobile device through the cantilever 2.

[0043] Specifically, the battery frame 1 and the cantilever 2 are formed into plastic parts by injection molding. Of course, it should be noted that the battery frame 1 and the cantilever 2 can also be mass-produced by designing a mold of a fixed shape. The present disclosure does not limit this, as long as the battery frame 1 and the cantilever 2 can be formed into an integrated structure and can be replaced in time after the battery frame 1 and the cantilever 2 are damaged.

[0044] In some embodiments, the battery of the present disclosure further includes a protection plate 5 and a battery cell 6, the contact 3 is provided on the protection plate 5, and the battery cell 6 is electrically connected to the protection plate 5, so as to be in contact and electrically connected with the body 7 of the mobile device through the contact 3. In specific implementation, the contact 3 is provided on the protection plate 5, and the protection plate 5 is connected to the electrode tab on the battery cell 6 to realize the electrical connection between the battery cell 6 and the protection plate 5, and when the contact 3 is in contact and electrically connected with the body 7, the mobile device can be powered by the battery cell 6.

[0045] Specifically, at least part of the protection plate 5 is embedded in the cantilever 2. It can be understood that the protection plate 5 is placed horizontally and arranged on the cantilever 2. The mobile device does not need to reserve a space for the protection plate 5 in the battery compartment. It only needs to reserve a battery compartment of the size of the battery cell 6 so that the battery cell 6 can be installed in the battery compartment, which can save space and make the mobile device compact.

[0046] Furthermore, at least part of the protection plate 5 is embedded in the cantilever 2, and the other part is exposed on the surface of the cantilever 2 facing the body 7. The contact 3 is arranged on the side of the protection plate 5 facing the body 7, so that the contact 3 can be in electrical contact with the body 7 and use the battery cell 6 to supply power to the mobile device.

[0047] Of course, the protection plate 5 can also be completely embedded in the cantilever 2, and a hole is opened on the side surface of the cantilever 2 facing the body 7 at the position corresponding to the contact 3 to expose the contact 3 so that the contact 3 can be electrically connected to the body 7 to supply power to the mobile device. It can be understood that the protection plate 5 is completely embedded in the cantilever 2, and the thickness of the mobile device is only increased by the thickness of the cantilever 2, and there is no need to increase the thickness of the protection plate 5, thereby saving the space occupied by the battery in the mobile device.

[0048] It should be noted that the protection plate 5 can also be partially embedded in the battery frame 1 and partially embedded in the cantilever 2. Such a setting can make the structure of the battery frame 1 and the cantilever 2 compact and save space. The present disclosure does not limit this and can be specifically set according to actual usage requirements.

[0049] Reference Figure 1As shown, a receiving groove is provided in the battery frame 1, and the battery cell 6 is provided in the receiving groove, and a double-sided adhesive layer is wrapped around the battery cell 6 and the outer side of the battery frame 1. It can be understood that the battery cell 6 can be limited and fixed in the receiving groove of the battery frame 1 by the double-sided adhesive layer to ensure a stable connection between the battery cell 6 and the protective plate 5; further, the double-sided adhesive layer can also adhere and fix the battery frame 1 and the battery cell 6 to the bottom of the battery compartment of the mobile device to prevent the battery from falling from the battery compartment, thereby improving the battery's anti-drop performance. Specifically, the double-sided adhesive layer forms a sealing layer on the outer side of the battery cell 6 and the battery frame 1, which can improve the waterproof performance of the battery.

[0050] Some other embodiments of the present disclosure provide a mobile device, comprising a battery as described in any of the above embodiments.
