As shown in fig. 1 and 2, the present application discloses an electronic device 10, wherein the electronic device 10 includes a control apparatus 100 for providing power support for and controlling operations of electronic components 14 in the electronic device 10.

The control device 100 includes a battery pack 200 and a main control board 300. A plurality of electronic components are fixed on the main control board 300, and the electronic components fixed on the main control board 300 can be controlled by the control chip on the main control board. The battery assembly 200 is electrically connected to the main control board 300 and can provide power support for electronic components fixed on the main control board 300. In the present embodiment, the electronic device 10 is a mobile phone. Of course, in other embodiments, the electronic device 10 may also be other devices with the battery assembly 200 and the main control board 300, such as: computers, tablets, e-books, watches, massage instruments, etc.

As shown in fig. 4 as necessary, the electronic device 10 further includes a device middle frame 400 and a back case 500, the device middle frame 400 and the back case 500 enclose an accommodating space 11 for accommodating the control device 100, and the battery pack 200 and the main control board 300 are fixed in the accommodating space 11. The device bezel 400 may also support and protect the battery assembly 200 and other electronic components of the electronic device 10 (e.g., speakers, headphones, a display screen, etc.).

As shown in fig. 1, in the present embodiment, a battery assembly 200 includes a battery cell 210 and a protective plate 220. The main control board 300 is electrically connected to the protection board 220, the battery cell 210 is electrically connected to the protection board 220, the main control board 300 is electrically connected to the protection board 220, and the protection board 220 can play a role in electrical protection for the battery cell 210, for example: the protection board 220 can perform under-voltage protection, over-current protection, over-temperature protection and the like on the battery cell 210. Specifically, the battery cell 210 includes a positive electrode B + and a negative electrode B-, which are connected to the protection circuit of the protection plate 220 via a tab 230. The protection plate 220 also includes a positive electrode P + and a negative electrode P-, the positive electrode P + and the negative electrode P-of the protection plate 220 are respectively connected to a positive electrode B + and a negative electrode B-of the battery cell 210 through a protection circuit and a tab 230.

The accommodation space 11 includes a battery compartment 12 and a control compartment 13. The battery compartment 12 and the control compartment 13 are disposed adjacent to each other in the longitudinal direction X of the electronic apparatus 10.

As shown in fig. 3, in one design, the battery assembly 200 is secured to the battery compartment 12, i.e., both the battery cell 210 and the protective plate 220 are secured in the battery compartment 12. The main control board 300 is fixed in the control chamber 13 adjacent to the battery chamber 12, and the protection board 220 and the main control board 300 are electrically connected through the connector 600. At this time, the protection plate 220 occupies a part of the space of the battery compartment 12, so that the space occupation ratio of the battery in the battery compartment 12 cannot be greatly increased.

As shown in fig. 1 and 2, in the present design, the battery cell 210 is fixed to the battery compartment 12, and the protection board 220 and the main control board 300 are located outside the battery compartment 12. Specifically, the protection board 220 is disposed above the main control board 300, in other words, the protection board 220 is disposed in the control cabin 13. In the above arrangement, the protection plate 220 is disposed above the main control plate 300, and the space of the battery compartment 12 occupied by the protection plate 220 can be avoided or reduced. When the protection board 220 is not required to be disposed in the battery compartment 12, the volume of the battery cell 210 may be further enlarged, and the specific space of the battery cell 210 in the battery compartment 12 is enlarged to the greatest extent, that is, the volume of the battery cell 210 is increased, and the capacity of the battery cell 210 is enlarged, so as to improve the cruising ability of the electronic device 10 (see fig. 1). Alternatively, after the protection board 220 is fixed above the main control board 300, if the size of the battery cell 210 is not greatly increased, the volume originally used for accommodating the protection board 220 in the battery compartment 12 may be used to accommodate other electronic components, i.e., the extra profit margin 15 is obtained. The internal space of the electronic device 10 is thus arranged, which is beneficial to the light and thin design of the electronic device 10 (refer to fig. 2).

Further, as shown in fig. 4 and 5. The protection plate 220 and the main control plate 300 are spaced apart in the thickness direction H of the electronic device 10, that is, the protection plate 220 and the main control plate 300 have a certain gap in the thickness direction H. The main control board 300 needs to fix other electronic components 14. The electronic component 14 has a certain thickness, and by the above arrangement, the protection board 220 can be arranged above the main control board 300 in an overhead manner, so that a space for accommodating the electronic component 14 is defined between the protection board 220 and the main control board 300, thereby reasonably utilizing the space in the electronic device 10. Meanwhile, on the premise of changing the arrangement of the protection plate 220, the arrangement mode of other electronic parts 14 does not need to be changed, and the process flow is simplified.

Specifically, as shown in fig. 1 and 4, the battery assembly 200 further includes a pin 700, one end of the pin 700 is fixed to the protection plate 220, and the other end of the pin 700 is fixed to the main control board 300. The pins 700 have a certain length, and the protection plate 220 may be arranged above the main control board 300 in an overhead manner, so that the main control board 300 and the protection plate 220 are arranged at an interval in the thickness direction H.

Meanwhile, the contact pin 700 is made of a metal conductive material, and one end of a part of the contact pin 700 fixed to the protection plate 220 can be electrically connected to the positive electrode P + of the protection plate 220, so that the main control board 300 is electrically connected to the positive electrode P + of the protection plate 220 and the positive electrode B + of the battery cell 210. One end of the other part of the pins 700 fixed to the protection plate 220 may be electrically connected to the negative electrode P-of the protection plate 220, so as to electrically connect the main control plate 300 with the negative electrode P-of the protection plate 220 and the negative electrode B-of the battery cell 210. In summary, the pin 700 not only can support the protection plate 220 to make the protection plate 220 and the main control board 300 spaced apart, but also can electrically connect the protection plate 220 and the main control board 300.

In this embodiment, the number of the pins 700 is plural, one part of the pins 700 is located at one end of the protection plate 220, and the other part of the pins 700 is located at the other side of the protection plate 220. With the above arrangement, the protection plate 220 is stably supported. Of course, in other embodiments, the pins 700 may be uniformly fixed on the protection plate 220, or only fixed on a local area (e.g., a middle portion) of the protection plate 220, etc.

In other embodiments, the protective plate 220 may not be supported and positioned by the metal pins 700. As shown in fig. 5, in this embodiment, the battery assembly 200 further includes an insulating support 800, and both ends of the insulating support 800 are fixedly connected to the protection plate 220 and the main control plate 300, respectively. The insulating support 800 may support the protection plate 220 to function as an overhead protection plate 220 such that the protection plate 220 and the main control plate 300 are spaced apart. The battery assembly 200 further includes a flexible wire 900, and the flexible wire 900 is electrically connected to the protection board 220 and the main control board 300, so as to electrically connect the protection board 220 and the main control board 300.

Further, the control device 100 includes a shield case (not shown) and a charger (not shown). The charger and the shield cover are fixed on the main control board 300, and the shield cover is arranged above the charger. The electronic device 10 is further provided with a charging female terminal (not shown), and the charging female terminal is electrically connected to the charger. When the battery pack 200 of the electronic device 10 needs to be charged, the external power source is inserted and fixed with the charging female connector through the charging male connector, so that the external power source is electrically connected to the charger. The charger is also electrically connected to the protection circuit of the protection board 220 through the main control board 300, and is finally electrically connected to the battery cell 210 through the protection circuit, so that an external power supply is electrically connected to the battery cell 210 to charge the battery cell 210. In the process, the charger generates a high-frequency signal, which may cause large interference to the antenna in the electronic device 10, thereby affecting the reception or transmission of signals by the electronic device 10. In the embodiment, the interference of the charger to the antenna in the working process can be reduced or avoided by arranging the shielding cover.

In this embodiment, as shown in fig. 4 in conjunction with the projection 1, a plane on which an end surface of the protection plate 220 away from the main control board 300 is located is defined as a first plane 221, and a plane on which an end surface of the shield case away from the main control board 300 is located is defined as a second plane. The first plane 221 coincides with the second plane, or the first plane 221 is located on a side of the second plane close to the main control board 300. In general, the shield case is a component occupying the largest thickness space on the main control board 300. Through the arrangement, the problem that the thickness of the electronic device 10 is increased due to the change of the position of the protection plate 220 can be avoided, and the reasonable optimization of the internal space of the electronic device 10 is further realized.

Further, a plane where the main control board 300 is located is taken as a bottom plane 310, and a plane where an end surface of the battery cell 210 far away from the bottom plane 310 is located is taken as a third plane 211. The first plane 221 coincides with the third plane 211, or the first plane 221 is located on a side of the third plane 211 close to the bottom plane 310. Through the above arrangement, the position of the protection plate 220 can be transferred without changing the structure of the original back shell 500, that is, the protection plate is moved to the control cabin 13, so that the size of the battery cell 210 can be enlarged, the duty ratio of the battery cell 210 in the battery cabin 12 can be improved to the maximum extent, and the power storage performance of the electronic device 10 can be improved.

It should be noted that the first plane 221 and the third plane 211 are both close to the surface of the back shell 500.

When hot, in other embodiments, the first plane 221 is located on a side of the third plane 211 away from the bottom plane 310, in other words, the first plane 221 of the protection plate 220 is closer to the back case 500 than the third plane 211 of the battery cell 210. At this time, a partial structure of the back case 500 protrudes outward. In the above design, the surface where the back case 500 is located is not a flat surface, and the receiving space 11 may be provided for the protection plate 220. Meanwhile, the position corresponding to the battery cell 210 is recessed inwards, so that a recessed holding position beneficial for a user to hold can be formed.

Further, the projection of the protection plate 220 in the thickness direction H falls within the projection of the main control plate 300 in the thickness direction H. In the above arrangement, the main control board 300 is located in the control cabin 13 and does not occupy the space of the battery cabin 12. Through the above arrangement, it is ensured that the protection plate 220 completely enters the control cabin 13, and the space occupied by the protection plate in the battery cabin 12 is avoided, so that the size of the battery cell 210 is favorably enlarged, the duty ratio of the battery cell 210 in the battery cabin 12 is improved to the maximum extent, and the power storage performance of the electronic device 10 is improved.
