Description

Technical Field

[0001] The present disclosure relates to the field of battery technology, and in particular to a battery and a mobile device. Background Art

[0002] In order to make battery replacement more convenient, mobile phones are designed with detachable battery structures, which can be removed by users themselves, making battery replacement easier. Existing detachable batteries mostly use a metal pad structure, which consists of a battery cell, a protection board, and a rubber frame. The connection pad is designed on the protection board surface, which is set on the top of the battery cell and packaged as an integral structure. When the battery is installed in the body of the mobile device, the battery is connected to the body through the metal pad.

[0003] At a time when current mobile phones are all pursuing fast charging and large batteries, when charging, the battery of this structure will concentrate the heat at the contact position. The contact position generates high heat and the temperature rises too quickly. Since the battery package is an integral structure, the heat dissipation is poor, posing a safety hazard.

[0037] 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.

[0038] 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.

[0039] The battery and the mobile device are described in detail below through specific embodiments:

[0040] Reference Figures 1 to 4 As shown, some embodiments of the present invention provide a battery, comprising a battery body 1 and a first connection point 2 .

[0041] Among them, the first connection position 2 is arranged on one side of the battery body 1 and extends in a direction away from the battery body 1. The first connection position 2 is configured to be plugged and connected with the second connection position 3 on the body 4 of the mobile device, that is, the first connection position 2 is arranged on the battery body 1, and the second connection position 3 is arranged on the body 4 of the mobile device, and the first connection position 2 is plugged and connected with the second connection position 3, which can connect the battery to the mobile device and supply power to the mobile device. The structure is simple, easy to disassemble, and supports plugging and unplugging.

[0042] Among them, the first connection position 2 has a first conductive contact 21 electrically connected to the battery body 1, and the first conductive contact 21 is configured to contact and conduct with the second conductive contact on the second connection position 3 when the first connection position 2 and the second connection position 3 are plugged in. It can be understood that compared with the structure in which the connection pad is designed on the surface of the protective plate 12 at the top of the battery cell 11, since the first connection position 2 in the present disclosure extends in a direction away from the battery body 1 to exceed the battery body 1, the first conductive contact 21 is set on the first connection position 2, so that the size and number of the first conductive contact 21 will not be affected by the layout of the components on the battery body 1, so that the size and number of the first conductive contact 21 can be flexibly adjusted according to actual needs, thereby increasing the area of ​​the contact conduction area between the battery and the mobile device, facilitating heat dissipation, and improving the temperature rise of the contact conduction area between the first conductive contact 21 and the second conductive contact during fast charging; at the same time, this can also increase the charging speed by increasing the area of ​​the first conductive contact 21 and increasing the number of the first conductive contacts 21, thereby achieving the requirement of fast charging.

[0043] It can be understood that the first conductive contact 21 is arranged on the first connection position 2, and the first connection position 2 is arranged on the protective plate 12 of the battery body 1, so that the first conductive contact 21 is not affected by the layout of components on the protective plate 12, and the area and number of the first conductive contact 21 can be set according to actual usage requirements to meet the fast charging requirements.

[0044] It should be noted that four first conductive contacts 21, namely P+, P-, ID and NTC, are provided on the first connection position 2. The P+ contact and the P- contact serve as the positive and negative poles of the battery and are used to power the mobile device. The ID contact and the NTC contact are used to provide and identify the temperature information of the battery to the mobile device to prevent excessive current in the circuit.

[0045] In some embodiments, reference Figure 3 As shown, the first connection position 2 is higher than the surface of the battery body 1. It can be understood that the first connection position 2 is higher than the surface of the battery body 1, and the second connection position 3 corresponding to the first connection position 2 is also higher than the surface of the body 4 and the battery body 1. In this way, the first connection position 2 and the second connection position 3 can be plugged first, and then the battery body 1 can be installed in the battery compartment on the body 4 of the mobile device, which is convenient for plugging.

[0046] When removing the battery body 1, turn the mobile device over with the battery compartment opening facing downward, and the battery body 1 falls out of the battery compartment under the action of gravity, and then the first connection position 2 is pulled out from the second connection position 3, making the installation and removal of the battery body 1 simple and convenient.

[0047] In a specific implementation, the first connection position 2 includes a first folded edge 22 and a second folded edge 23 connected to each other.

[0048] The first folded edge 22 is extended from the surface of the battery body 1 in a direction away from the battery body 1, the second folded edge 23 is extended in a direction parallel to the surface of the battery body 1 away from the battery body 1, the height of the second folded edge 23 is higher than the surface of the battery body 1, and the first conductive contact 21 is arranged on the second folded edge 23. It can be understood that the battery body 1 has two surfaces and four side edges connecting the two surfaces, the first folded edge 22 is extended from one side surface of the battery body 1 in a direction away from the battery body 1, and the height of the end of the first folded edge 22 away from the battery body 1 is higher than the surface of the battery body 1, and the second folded edge 23 is extended from the end of the first folded edge 22 away from the battery body 1 in a direction parallel to the surface of the battery body 1, so that the second folded edge 23 can be arranged beyond the surface of the side of the battery body 1.

[0049] Specifically, the first conductive contact 21 is arranged on the second folded edge 23, and the second folded edge 23 is arranged beyond the surface of the side of the battery body 1, so that the area and number of the first conductive contact 21 are not limited by the size of the battery body 1, and can be specifically arranged according to actual usage requirements.

[0050] Of course, the first connection position 2 can also be flush with the surface of the battery body 1, and the present disclosure does not limit this, as long as it can be set corresponding to the second connection position 3 and can be plugged in to power the mobile device. It should be noted that the first connection position 2 can also be a structure of other shapes, as long as the first connection position 2 can exceed the surface of the side of the battery body 1 so that the first conductive contact 21 can be set on the first connection position 2. Specifically, the area of ​​the first connection position 2, and the area and number of the first conductive contacts 21 set on the first connection position 2 can be set according to actual needs, and the present disclosure does not limit this.

[0051] Continue to refer to Figure 3 As shown, the number of the first connection positions 2 is two, and the two first connection positions 2 are arranged at intervals on one side of the battery body 1. It can be understood that the first conductive contacts 21 are arranged on both first connection positions 2, and the total area of ​​the first conductive contacts 21 and the second conductive contacts in contact and conduction can be increased by increasing the number of the first conductive contacts 21 and correspondingly increasing the number of the second conductive contacts, thereby increasing the contact area between the battery and the mobile device, facilitating heat dissipation, and improving the temperature rise of the contact and conduction area between the battery and the mobile device during fast charging.

[0052] Specifically, the first connection position 2 has a first surface and a second surface opposite to each other, and the first surface and the second surface are both provided with a first conductive contact 21. In other words, the first surface and the second surface of the first connection position 2 are both provided with a first conductive contact 21, that is, the first surface and the second surface opposite to each other of the first connection position 2 can both be in contact with the second connection position 3 for conduction, which can speed up the charging speed and meet the charging demand.

[0053] In some embodiments, reference Figure 3 As shown, the battery body 1 includes a battery cell 11 and a protection plate 12 electrically connected to the battery cell 11. The battery cell 11 is used to supply power to the mobile device. The protection plate 12 is arranged on one side of the battery cell 11. The first connection position 2 is arranged on the protection plate 12 and extends in a direction away from the protection plate 12. It can be understood that the battery cell 11 and the protection plate 12 are packaged as one body and installed together in the battery compartment. The first connection position 2 extends in a direction away from the protection plate 12 to exceed the surface of the battery cell 11 and the protection plate 12. In this way, the area and number of the first conductive contacts 21 are not limited to the size of the protection plate 12, and can be specifically set according to actual usage requirements.

[0054] Some other embodiments of the present disclosure provide a mobile device, including a body 4 and a battery as described in any of the above embodiments.

[0055] The mobile device provided by the embodiment of the present disclosure includes the battery of the above embodiment and thus has the beneficial effects of the battery of the above embodiment, which will not be described in detail here.

[0056] In a specific implementation, a second connection position 3 is provided on the body 4, and a second conductive contact is provided on the second connection position 3. The second conductive contact can be in contact with the first conductive contact 21 to conduct electricity, so as to supply power to the body 4 of the mobile device through the battery.

[0057] In some embodiments, reference Figure 4 As shown, the second connection position 3 includes a first clamping plate 31 and a second clamping plate 32 connected to each other, an insertion gap is formed between the first clamping plate 31 and the second clamping plate 32, the first connection position 2 is inserted in the insertion gap, and a second conductive contact is provided at a position of the first clamping plate 31 and / or the second clamping plate 32 corresponding to the first conductive contact 21.

[0058] It is understandable that the first conductive contact 21 can be arranged on the first and / or second surfaces opposite to the first connection position 2 as required, and the second conductive contact is arranged corresponding to the first conductive contact 21 to achieve contact electrical connection with the second conductive contact through the first conductive contact 21 .

[0059] That is to say, when the first conductive contact 21 is arranged on the first surface, a second conductive contact is arranged on one of the first clamping plate 31 and the second clamping plate 32 corresponding to the first conductive contact 21; or, the first conductive contact 21 is arranged on both the first surface and the second surface, and correspondingly, the first clamping plate 31 and the second clamping plate 32 are respectively arranged with a second conductive contact, so that the first surface and the second surface of the first connection position 2 can both achieve contact and electrical connection with the second connection position 3. Specifically, the distribution of the first conductive contact 21 and the second conductive contact can be specifically set according to actual charging needs, and the present disclosure does not limit this.

[0060] Further, continue to refer to Figure 4 As shown, a first sawtooth structure 311 is provided on a side surface of the first clamping plate 31 close to the second clamping plate 32, a second sawtooth structure 321 is provided on a side surface of the second clamping plate 32 close to the first clamping plate 31, and the first connecting position 2 is sandwiched between the first sawtooth structure 311 and the second sawtooth structure 321. It can be understood that an insertion gap is formed between the first sawtooth structure 311 and the second sawtooth structure 321, and under the bite action of the first sawtooth structure 311 and the second sawtooth structure 321, the first connecting position 2 can be inserted and fixed in the insertion gap.

[0061] Of course, the first connection position 2 can also be plugged in and fixed in the second connection position 3 through other structures, and the present disclosure does not limit this, as long as the first connection position 2 and the second connection position 3 can be electrically connected and the mobile device can be powered by a battery.

[0062] In a specific implementation, both the first sawtooth structure 311 and the second sawtooth structure 321 are elastic structures, and are configured to be elastically deformed and pressed against the first connection position 2. That is, during the insertion of the first connection position 2 into the insertion gap, the first sawtooth structure 311 and the second sawtooth structure 321 can be elastically deformed, and the first sawtooth structure 311 and the second sawtooth structure 321 can be pressed against the first surface and the second surface of the first connection position 2, respectively, to prevent the first connection position 2 from coming out, ensure stable connection, and thus provide stable current to the mobile device.

[0063] Furthermore, the first serration structure 311 and the second serration structure 321 can be made of elastic material so as to undergo elastic deformation during the process of inserting the first connection position 2 into the insertion gap; the first serration structure 311 and the second serration structure 321 can also be retracted or extended relative to the first clamping plate 31 and the second clamping plate 32 respectively, so that the first connection position 2 can be inserted into the insertion gap, and the first serration structure 311 and the second serration structure 321 can also be extended toward the direction of the first connection position 2 to be pressed on the first connection position 2, thereby ensuring that the first connection position 2 and the second connection position 3 can be stably connected.

[0064] Of course, the first sawtooth structure 311 and the second sawtooth structure 321 can also be other elastic structures, and the present disclosure does not limit this. It only needs to be possible to press the first connection position 2 between the first sawtooth structure 311 and the second sawtooth structure 321 to achieve electrical contact connection between the first connection position 2 and the second connection position 3 and supply power to the mobile device through the battery.

[0065] In some embodiments, the body 4 has a battery compartment for accommodating batteries, and the battery compartment has an opening for the batteries to enter and exit.

[0066] In a specific implementation, the second connection position 3 is located outside the opening and is higher than the plane where the opening is located. It can be understood that the second connection position 3 is set on the body 4 located outside the opening and is higher than the plane where the opening is located, that is, the second connection position 3 can be set beyond the surface of the battery body 1 and is set corresponding to the height of the first connection position 2, so that the first connection position 2 and the second connection position 3 can be plugged and connected to power the mobile device through the battery.

[0067] Of course, it should be noted that the second connection position 3 can also be arranged flush with the surface of the battery body 1, and the present disclosure does not limit this, as long as it can correspond to the height of the first connection position 2 to facilitate plugging and unplugging.

[0068] The battery and mobile device provided by the embodiments of the present disclosure have the following advantages:

[0069] (1) The first connection position on the battery is higher than the surface of the battery body, and the second connection position corresponding to the first connection position is also higher than the surface of the body and the battery body, making the installation and removal of the battery body simple and convenient;

[0070] (2) The first conductive contact is arranged at the first connection position, and the area and number of the first conductive contact can be set according to actual use requirements, which can meet the fast charging requirements. Increasing the number of the first conductive contacts can make the heat dissipation in the contact conduction area fast and the charging and discharging temperature rise low;

[0071] (3) The setting position of the first connection position can be adjusted according to the requirements of the mobile device and is not affected by the layout of components on the protection board;

[0072] (4) The first connection position and the second connection position are connected by a bite-type structure, which is stable and can provide stable current to the mobile device.

[0073] It should be noted that, in this article, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0074] The above are only specific embodiments of the present disclosure, so that those skilled in the art can understand or implement the present disclosure. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present disclosure.
