DETAILED DESCRIPTION

[0050] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved more clearly, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.

[0051] In the description of this utility model, unless otherwise expressly specified or limited, the terms "connected" and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0052] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.

[0053] With the development of science and technology and the growing demand for electronic devices, terminal devices are widely used in our lives. Mobile terminals refer to terminal devices that can be used on the move.

[0054] Some large-sized terminal devices do not have internal batteries. For example, learning machines larger than 14 inches basically do not have batteries. This means that they must be connected to an external power supply when in use, which is inconvenient.

[0055] There are also some terminal devices that have batteries inside, but the batteries are generally not removable. Or during the battery removal process, the disassembly force may damage the battery. For example, many batteries are directly fixed inside the terminal device with glue or strong double-sided tape. If the battery is forcibly removed and pulled out, the glue will easily pull the battery shell, causing damage to the battery. In the related art, the battery of the terminal device cannot be removed after installation, or the battery will be damaged after removal. This will result in: first, during the factory assembly of the terminal device, it is difficult to repair the battery after it is fixed. If the battery is installed incorrectly, it is difficult to remove the battery and reinstall it; second, batteries with good performance are difficult to remove for recycling and reuse, resulting in waste.

[0056] In addition, for terminal devices with a thin and light design, such as large-sized learning machines with a thin and light design, the device thickness is very small and the space reserved for battery installation is very small, making it difficult to make a detachable battery compartment.

[0057] Based on this, refer to Figures 1 to 14 The present application provides a battery fixing structure suitable for use in mobile terminals. The battery fixing structure of the present application is suitable for small and medium-sized mobile terminals such as 6 inches and 10 inches, and is also suitable for large-sized mobile terminals such as 13 inches and 14 inches.

[0058] This battery mounting structure enables installation or removal of the battery assembly 100 by assembling or separating the second mounting portion 21 from the first mounting portion 11. The removable battery assembly 100 facilitates inspection, repair, or recycling of the batteries 30, reducing costs. When removing the battery assembly 100, external forces act on the mounting plate 20 rather than on the batteries 30, preventing them from being pulled during removal. This allows for non-destructive removal of the batteries 30, allowing for the reuse of good batteries 30 and maximizing resource utilization.

[0059] The battery assembly 100 in the mobile terminal is easy to disassemble, which makes it easy to disassemble the battery 30, repair the battery 30 during factory assembly, repair faulty batteries 30 after sales, and recycle and reuse batteries 30 with good performance in the mobile terminal to reduce losses.

[0060] The mobile terminal of the present application can be a learning machine, a learning tablet, a reader, a gaming tablet, a mobile phone, a smart wearable device, etc.

[0061] Please continue to refer to Figures 1 to 17 , the battery fixing structure and the mobile terminal including the battery fixing structure are described below.

[0062] like Figure 5 、 Figures 11 to 15 As shown, the mobile terminal includes a battery fixing structure, a circuit board 60, etc.

[0063] like Figures 2 to 6 、 Figure 14 As shown, the battery fixing structure includes a mounting member 10 and a battery assembly 100 . Figure 1 The diagram illustrates a battery assembly 100, which includes a battery 30 and a fixing plate 20. The battery 30 is electrically connected to the circuit board 60 via an electrical connection line 70. In the battery assembly 100, the battery 30 is mounted to the fixing plate 20 by gluing or other means, thereby securing the battery 30 relative to the fixing plate 20. To facilitate installation of the battery assembly 100, the mounting member 10 is provided with a first mounting portion 11, and the fixing plate 20 is provided with a second mounting portion 21. The second mounting portion 21 is detachably connected to the first mounting portion 11. The battery assembly 100 can be detachably mounted to the mounting member 10 via the fixing plate 20, thereby enabling the battery assembly 100 to be detachably mounted to the mounting member 10.

[0064] The second mounting portion 21 being detachably connected to the first mounting portion 11 means that the second mounting portion 21 is connected to the first mounting portion 11 and can be disconnected from the first mounting portion 11 when necessary. The second mounting portion 21 and the first mounting portion 11 can be connected by a fastener 90, a snap connection, a Velcro connection, a magnetic connection, or the like.

[0065] Reference Figure 4 、 Figure 12 The battery 30 and the circuit board 60 are electrically connected through an electrical connector so that power is supplied to the circuit board 60 through the battery 30.

[0066] The battery fixing structure of the present application mounts the battery 30 on the fixing plate 20, and the fixing plate 20 and the mounting member 10 can be assembled, fixed, or separated from each other as needed. In this way, if the battery 30 needs to be reinstalled, repaired, replaced, or recycled, the fixing plate 20 can be removed from the mounting member 10 to remove the battery assembly 100 from the mounting member 10, thereby removing the battery 30.

[0067] The battery fixing structure and mobile terminal of the present application have the following beneficial effects:

[0068] First, the present application facilitates the disassembly of the battery 30 , the battery 30 is not easily damaged during disassembly, and the battery 30 can be reliably installed.

[0069] The traditional battery 30 is fixed to the mobile terminal housing by strong glue, and the battery 30 cannot be removed. If the battery 30 is forcibly removed, the outer surface of the battery 30 will be pulled by the adhesive material when the battery 30 is pulled out, which can easily damage the battery 30 and make it impossible to reuse the battery 30.

[0070] The inventor has also considered that when installing the battery 30, the battery 30 can be placed directly on the casing of the mobile terminal, and then a cover can be added to cover the outside of the battery 30. The position of the battery 30 can be restricted by the cover to fix the battery 30. However, this will make the heat dissipation of the battery 30 more difficult. In addition, the battery 30 is not connected to other objects inside the casing and the cover. When the mobile terminal is in use, the battery 30 is prone to shaking and causing abnormal noises. The movement of the battery 30 can also easily cause the electrical connection line 70 connected between the battery 30 and the circuit board 60 to be pulled, which may cause the connection between the battery 30 and the circuit board 60 to loosen and lose power, resulting in a malfunction.

[0071] In the present application, the battery 30 mounting member 10 is installed on the fixing plate 20. When the battery 30 needs to be disassembled, it is only necessary to remove the fixing plate 20 from the mounting member 10 to disassemble the battery assembly 100. During disassembly, external force will not directly act on the outer skin of the battery 30, and the battery 30 will not be accidentally damaged when the battery assembly 100 is disassembled, which facilitates the reuse of the battery 30 later.

[0072] Furthermore, there is no need to add an extra cover on the side of the battery 30 away from the mounting member 10, which would affect the heat dissipation of the battery 30. The way the battery 30 is mounted on the fixing plate 20 is not limited, as long as the battery 30 is not easily shaken during normal use of the mobile terminal.

[0073] Second, the battery fixing structure occupies a relatively small thickness and is suitable for use in thin and lightweight mobile terminals.

[0074] Third, when assembling a mobile terminal in a factory, if the battery assembly 100 is installed incorrectly, for example, the battery assembly 100 is of the wrong model, or a defective battery assembly 100 is installed on the mounting part 10 due to misoperation, or the battery 30 is installed in the wrong direction, the battery assembly 100 that has been installed on the mounting part 10 can also be removed and the battery assembly 100 can be reinstalled.

[0075] Fourth, during after-sales repairs of the mobile terminal, the battery assembly 100 can be removed to inspect the performance of the battery 30, making the inspection more convenient. When replacing the battery 30 of the mobile terminal after sales, since the fixing plate 20 and the mounting member 10 are not fixed by adhesive, no adhesive will remain on the mounting member 10 after the battery assembly 100 is removed, which will not affect the reinstallation of the new battery assembly 100 on the mounting member 10.

[0076] Fifth, for the batteries 30 with good performance in the mobile terminal, the entire battery assembly 100 can be disassembled and the good batteries 30 can be recycled to avoid waste and save costs.

[0077] In one embodiment, the terminal device includes a display panel 500, a housing, and a battery fixing structure disposed within the housing. The mounting member 10 is connected to the housing of the terminal device via fasteners 90, snap-fit ​​connections, welding, or other methods. The fixing plate 20 of the battery assembly 100 is detachably connected to the mounting member 10. To remove the battery 30, the mounting member 10 need not be removed. Instead, the housing of the terminal device need only be opened to remove the battery assembly 100 from the mounting member 10 secured to the housing.

[0078] In another embodiment, the terminal device includes a housing, which serves as a mounting member 10 for the battery 30 mounting structure, and the fixing plate 20 of the battery assembly 100 is detachably connected to the housing. Optionally, the housing includes a frame 300 that at least partially surrounds the display panel 500 and a rear housing 400 that covers the rear side of the frame 300, and the fixing plate 20 of the battery assembly 100 is detachably connected to the frame 300. When the battery 30 needs to be removed, it is only necessary to open the rear housing 400 and remove the fixing plate 20 of the battery assembly 100 from the frame 300.

[0079] In one embodiment, please refer to Figure 2 、 Figure 3 、 Figure 6 The mounting member 10 is a mounting plate, and the first mounting portion 11 of the mounting plate and the second mounting portion 21 of the fixing plate 20 can be locked at least by means of a fastener 90, thereby realizing a detachable connection between the first mounting portion 11 and the second mounting portion 21, and further realizing the detachable installation of the battery assembly 100 on the mounting member 10.

[0080] Optionally, the battery 30 is located on the side of the fixing plate 20 away from the mounting plate. The battery 30 is located on the side of the fixing plate 20 away from the mounting plate. During the installation of the battery assembly 100 to the mounting plate, the battery 30 is visible and not blocked, avoiding damage to the battery 30. It is also beneficial for the battery 30 to be closer to the rear shell 400 in the future, which is beneficial for the heat dissipation of the battery 30. In addition, the stacking arrangement of the battery 30, the fixing plate 20, and the mounting plate is beneficial to reducing the overall thickness of the battery fixing structure, thereby making the battery fixing structure suitable for use in mobile terminals with a lightweight design. Moreover, the battery 30 is located on the side of the fixing plate 20 away from the mounting plate, which allows the fixing plate 20 to be closer to the mounting plate, making it easy for the fixing plate 20 and the mounting plate to connect and support each other, and the installation and fixing operation between the two plates is easier and more reliable. Using the mounting plate as the mounting part 10, the mounting plate can reliably support the battery assembly 100.

[0081] In other embodiments, the mounting member 10 may also be a mounting frame, the battery 30 is located on the side of the fixing plate 20 facing away from the mounting frame, the edge area of ​​the fixing plate 20 is placed on the mounting frame, and the fixing plate 20 is detachably mounted on the mounting frame by locking, snapping, or the like with fasteners 90.

[0082] Alternatively, the mounting member 10 is a mounting frame, the battery 30 is located on a side of the fixing plate 20 close to the mounting frame, the area of ​​the fixing plate 20 is larger than the area of ​​the battery 30, the edge area of ​​the fixing plate 20 is exposed, the battery 30 is embedded in the interior of the mounting frame, the edge of the fixing plate 20 is placed on the mounting frame, and the fixing plate 20 is detachably mounted on the mounting frame by locking, snapping, or the like with fasteners 90.

[0083] In one embodiment, an adhesive layer 50 is provided between the battery 30 and the fixing plate 20, and the battery 30 is adhered to the fixing plate 20 through the adhesive layer 50, so that the battery 30 and the fixing plate 20 are relatively fixed. The adhesive method of installing the battery 30 is convenient and quick.

[0084] Optionally, the adhesive layer 50 is double-sided tape. In other embodiments, the adhesive layer 50 may be a layer of material formed by curing glue. It should be noted that, since the battery 30 and the fixing plate 20 are installed and removed as a whole during installation and removal, the battery 30 is installed and removed on the fixing plate 20 by gluing, which is both convenient and quick, and does not affect the overall installation, use, removal, maintenance, and recycling of the battery assembly 100.

[0085] In other embodiments, the battery 30 may not be adhered to the fixing plate 20 , and the battery 30 may be installed by pressing the battery 30 against the fixing plate 20 via the bracket 40 , as long as the battery 30 and the fixing plate 20 can be relatively fixed.

[0086] In one embodiment, please refer to Figures 2 to 6 、 Figures 11 to 14 The battery fixing structure also includes at least one bracket 40 for limiting the position and fixing the battery 30. The bracket 40 and the battery 30 are arranged on the same side of the fixing plate 20. The bracket 40 is connected to the fixing plate 20 or the mounting member 10. The bracket 40 and the battery 30 are abutted. The bracket 40 is used to limit the position of the battery 30 to enhance the stability and fixing effect of the battery 30. The positioning of the battery 30 by the bracket 40 prevents the battery 30 on the fixing plate 20 from loosening, shaking or falling off during manufacturing, testing, transportation and use, and also prevents the displacement of the battery 30 from pulling on the electrical connection line 70 between the battery 30 and the circuit board 60, causing connection failure.

[0087] It should be noted that the abutment between the bracket 40 and the battery 30 refers to the fact that the bracket 40 is used to support and limit the position of the battery 30. The abutment between the bracket 40 and the battery 30 can be either direct contact between the bracket 40 and the battery 30, or a buffer material or other structure can be provided between the bracket 40 and the battery 30, so that the bracket 40 indirectly abuts the battery 30, as long as the bracket 40 has a limiting effect on the battery 30. In this application, when describing component A and component B abutting, it can mean that component A exerts a certain force on component B, or that component A and component B are only in direct or indirect contact, and component A does not exert a force on component B.

[0088] The battery 30 has a first surface, a second surface 32, and multiple side surfaces 31. The first surface is located on the side of the battery 30 closest to the fixing plate 20, and the second surface 32 is located on the side of the battery 30 facing away from the fixing plate 20. The side surfaces 31 are connected between the first and second surfaces 32. The side surfaces 31 of the battery 30 abut against the bracket 40, which restricts lateral movement of the battery 30. The second surface 32 of the battery 30 abuts against the bracket 40, which restricts movement of the battery 30 away from the fixing plate 20.

[0089] Optionally, the battery 30 is adhered to the fixed plate 20 through the adhesive layer 50, and the battery 30 is offset against the bracket 40. The battery 30 can be well and stably fixed to the fixed plate 20 under the joint action of the adhesive material and the bracket 40. The battery assembly 100 has strong integrity and the battery 30 has a good fixing effect.

[0090] In one embodiment, the battery securing structure includes a plurality of brackets 40, some of which are first-type brackets 40 and some of which are second-type brackets 40. The first-type brackets 40 only abut against the side surfaces 31 of the battery 30. The second-type brackets 40 abut against both the side surfaces 31 and the second surface 32 of the battery 30.

[0091] In yet another embodiment, the battery fixing structure includes a plurality of brackets 40 , each bracket 40 abutting against both the side surface 31 and the second surface 32 of the battery 30 .

[0092] In another embodiment, the battery fixing structure includes a plurality of brackets 40 , each bracket 40 only abuts against the side surface 31 of the battery 30 , or each bracket 40 only abuts against the second surface 32 of the battery 30 .

[0093] In one embodiment, the bracket 40 supports the side 31 of the battery 30. Figures 2 to 4 The bracket 40 abuts against the side surface 31 of the battery 30 , and the bracket 40 is used to limit the battery 30 laterally to enhance the installation stability of the battery 30 .

[0094] For example, when the battery 30 is attached to the fixing plate 20 via adhesive material, a bracket 40 is provided on the side of the battery 30 to support the side 31 of the battery 30. During assembly of the terminal device, in subsequent steps after the battery 30 is installed, even if the battery 30 is subjected to external forces, such as accidentally pushing or pulling the battery 30, the bracket 40 supporting the side 31 of the battery 30 can prevent relative translation between the battery 30 and the fixing plate 20, thereby preventing the adhesive material between the battery 30 and the fixing plate 20 from being subjected to pulling forces, thus preventing damage to the adhesive strength and ensuring the installation stability of the battery 30. Of course, even if there is no adhesive material between the battery 30 and the fixing plate 20, the bracket 40 abutting the side 31 of the battery 30 is also conducive to maintaining the battery 30 in the target installation position on the fixing plate 20, thereby improving the fixation effect of the battery 30.

[0095] Optionally, each side 31 of the battery 30 abuts at least one bracket 40 , thereby securing the battery 30 in its current area through the bracket 40 , effectively securing the battery 30 . For example, the battery 30 has four sides 31 , all of which abut against the bracket 40 . Multiple brackets 40 can be provided, spaced apart around the battery 30 , to ensure that each side 31 of the battery 30 abuts against at least one bracket 40 ; alternatively, a frame-shaped bracket 40 can be provided to ensure that each side 31 of the battery 30 abuts against at least one bracket 40 .

[0096] It can be understood that by arranging multiple brackets 40 at intervals so that each side 31 of the battery 30 abuts against at least one bracket 40, not only the battery 30 is limited from multiple sides, making the position of the battery 30 more stable, but also the material and weight of the bracket 40 are saved and the cost is reduced; and it is convenient to adjust the position of the bracket 40 to adapt to batteries 30 of different sizes.

[0097] In other embodiments, part of the side surface 31 of the battery 30 abuts against the bracket 40 , while part of the side surface 31 does not abut against the bracket 40 .

[0098] Optionally, the battery fixing structure includes multiple brackets 40, each bracket 40 includes a bracket body 41, the bracket body 41 is an L-shaped structure, and each bracket body 41 includes a first bracket portion 411 and a second bracket portion 412 connected at an angle. When installing the bracket 40, the bracket 40 is set at the corner of the battery 30, and the first bracket portion 411 and the second bracket portion 412 respectively abut against two adjacent side surfaces 31 of the battery 30. After each bracket 40 is installed and fixed, the two side surfaces 31 of the battery 30 can be supported and limited, which is highly efficient.

[0099] like Figure 2 、 Figure 6 、 Figure 13 、 Figure 14For example, the battery fixing structure is provided with at least three brackets 40, which are respectively provided at the three corners of the battery 30. Each bracket 40 has an L-shaped bracket body 41. Each bracket 40 abuts two adjacent side surfaces 31 of the battery 30, so that all four side surfaces 31 of the battery 30 are restrained by the bracket 40. In other embodiments, the battery fixing structure may also be provided with only two brackets 40, each having an L-shaped bracket body 41. The two brackets 40 are respectively installed at two diagonal corners of the battery 30, which can also achieve support for all four side surfaces 31 of the battery 30. In other embodiments, the battery fixing structure may also be provided with four brackets 40, with each bracket 41 configured at each bracket portion of the battery 30.

[0100] In other embodiments, the brackets 40 may not be disposed at the corners of the battery 30, but four straight brackets 40 may be disposed in the middle of the upper, lower, left, and right sides 31 of the battery 30. It should be noted that in addition to the bracket 40 arrangement described in this specification, other bracket 40 arrangements may also be used.

[0101] In one embodiment, at least one bracket 40 in the battery fixing structure includes a bracket body 41 and a first pressing portion 42 connected to each other. The bracket body 41 is connected to the fixing plate 20 or the mounting member 10, and the bracket 40 is fixed by fixing the bracket body 41.

[0102] The bracket body 41 abuts against the side surface 31 of the battery 30 to laterally restrain the battery 30. The first pressing bracket portion 42 is located on the side of the battery 30 facing away from the fixing plate 20. The first pressing bracket portion 42 abuts against the second surface 32 of the battery 30 to restrain the battery 30 from the side facing away from the fixing plate 20.

[0103] When the bracket 40 and the fixing plate 20 are configured as a separate structure, when assembling the battery assembly 100, the battery 30 can first be adhered to the fixing plate 20 using double-sided tape or other adhesive material to achieve preliminary fixation of the battery 30. The bracket 40 can then be installed, and the first pressing portion 42 of the bracket 40 can be pressed against the side of the battery 30 facing away from the fixing plate 20, clamping the battery 30 between the fixing plate 20 and the first pressing portion 42 to strengthen the fixation of the battery 30. In this way, when the first pressing portion 42 is configured, the adhesive strength of the adhesive between the battery 30 and the fixing plate 20 is moderate and does not need to be too high, which can also meet the stability of the battery 30 fixation. A variety of adhesive materials can meet installation requirements.

[0104] In one embodiment, the battery fixing structure further includes a protective layer 80, which is disposed between the first pressing portion 42 and the second surface 32 of the battery 30. The first pressing portion 42 can not only serve as a limiter to restrict the movement of the battery 30 away from the fixing plate 20, but can also apply a suitable amount of pressure to the battery 30 (the pressure will not squeeze and damage the battery 30) to press and fix the battery 30. The provision of the protective layer 80 can, on the one hand, transmit suitable pressure to the battery 30 to fix the battery 30, and on the other hand, protect the battery 30. For example, even if the first pressing portion 42 has local protrusions or unevenness due to processing errors, because the protective layer 80 is disposed between the first pressing portion 42 and the battery 30, the local protrusions of the first pressing portion 42 will not directly press against the outer skin of the battery 30, thereby preventing damage to the outer skin of the battery 30.

[0105] The protective layer 80 may be a buffer structure, such as foam, to protect the battery 30. In other embodiments, the protective layer 80 may also be a flexible material such as double-sided tape with a certain thickness, as long as the first pressing portion 42 is prevented from directly contacting the outer skin of the battery 30.

[0106] In other embodiments, the first pressing portion 42 may be used only to limit the position of the battery 30, and the first pressing portion 42 does not apply pressure to the battery 30. For example, the first pressing portion 42 only contacts the protective layer 80, or the first pressing portion 42 only contacts the battery 30, and the battery 30 is not subjected to pressure from the first pressing portion 42.

[0107] In other embodiments, the bracket 40 includes a bracket body 41 and a first pressing portion 42 . The bracket body 41 is only used to connect to the fixing plate 20 or the mounting member 10 . The bracket body 41 does not abut against the side surface 31 of the battery 30 , and the first pressing portion 42 still abuts against the second surface 32 .

[0108] In one embodiment, the first pressing portion 42 blocks the battery 30 on the side facing away from the fixing plate 20 . The first pressing portion 42 blocks 3% to 30% of the area of ​​the second surface 32 of the battery 30 . This provides a pre-pressing function for the battery 30 while avoiding wasting material by making the first pressing portion 42 too large and preventing the first pressing portion 42 from affecting the heat dissipation of the battery 30 .

[0109] Please continue to refer to Figure 4 、 Figure 5 、 Figure 12In one embodiment, the terminal device includes an electrical connection cable 70 , one end of which is electrically connected to the battery 30 , and the other end of which is provided with a first electrical connector 72 . A second electrical connector 73 is provided on the circuit board 60 . The first electrical connector 72 is mounted on the second electrical connector 73 to electrically connect the battery 30 to the circuit board 60 , thereby providing power to the circuit board 60 and enabling the circuit board 60 to manage and control the battery 30 . Exemplarily, the first electrical connector 72 is a plug, and the second electrical connector 73 is a socket. The plug is inserted into the socket, and the battery 30 is electrically connected to the circuit board 60 via the electrical connection cable 70 , the electrical connector, and the circuit board 60 .

[0110] Optionally, the mounting member 10 of the battery fixing structure is a mounting plate, and the circuit board 60 is mounted and locked on the mounting plate.

[0111] Optionally, the battery securing structure includes one or more brackets 40, at least one of which includes a bracket body 41 and a second pressing portion 43. The bracket body 41 is connected to the fixing plate 20 or the mounting member 10, and the bracket 40 is fixed by the bracket body 41, and the bracket body 41 abuts against the battery 30. The second pressing portion 43 blocks the side of the first electrical connector 72 facing away from the second electrical connector 73. The second pressing portion 43 is used to limit the movement of the first electrical connector 72 in a direction away from the second electrical connector 73, so that the first electrical connector 72 remains mounted on the second electrical connector 73, thereby maintaining a reliable connection between the battery 30 and the circuit board 60.

[0112] The second pressing portion 43 abuts against the first electrical connector 72 , or the second pressing portion 43 and the first electrical connector 72 are spaced apart, and the space between the second pressing portion 43 and the first electrical connector 72 is not large enough to allow the first electrical connector 72 to detach from the second electrical connector 73 .

[0113] The inventors considered providing an additional, dedicated pre-pressing bracket 40 for pressing against the side of the first electrical connector 72 facing away from the second electrical connector 73 and the circuit board 60. However, this would require an additional material type and at least one additional installation step for the bracket 40, resulting in low installation efficiency and increased costs. In this embodiment, however, by designing a second pressing portion 43 within the bracket 40 used in the battery securing structure to limit and support the battery 30, the same bracket 40 serves both to limit and secure the battery 30 and to prevent the first electrical connector 72 from disengaging. This reduces the number of materials and associated installation steps required for the bracket 40 specifically used for pre-pressing the electrical connector, thereby improving installation efficiency and reducing costs.

[0114] In one embodiment, if Figure 4 、 Figure 9 、 Figure 10 、 Figure 14As shown, the battery 30 mounting structure includes a plurality of brackets 40 , at least one bracket 40 is a second type bracket 40 , and the second type bracket 40 includes a bracket body 41 , a first pressing portion 42 and a second pressing portion 43 .

[0115] The second type of bracket 40 is described in more detail below: the bracket body 41 and the battery 30 are disposed on the same side of the fixing plate 20, and the bracket body 41 is connected to the fixing plate 20 or to the mounting member 10. The circuit board 60 is disposed lateral to the battery assembly 100, with the bracket body 41 positioned between the battery 30 and the circuit board 60. A first pressing portion 42 and a second pressing portion 43 are connected to opposite sides of the bracket body 41. The first pressing portion 42 blocks the battery 30 on the side facing away from the fixing plate 20, while the second pressing portion 43 blocks the first electrical connector 72 on the side facing away from the circuit board 60. The first pressing portion 42 limits the battery 30 to prevent it from separating from the fixing plate 20, while the second pressing portion 43 limits the first electrical connector 72 to prevent it from separating from the second electrical connector 73 of the circuit board 60. For example, if the battery assembly 100 and the circuit board 60 are spaced apart along the direction of application, the first pressing portion 42 and the second pressing portion 43 are respectively disposed on the left and right sides of the bracket body 41.

[0116] Optionally, the bracket body 41 of the second type bracket 40 further abuts against the side surface 31 of the battery 30 to limit lateral movement of the battery 30 .

[0117] Please continue to refer to Figure 4 、 Figure 9 、 Figure 10 、 Figure 14 A first pressing portion 42 and a second pressing portion 43 are provided on the bracket 40 disposed between the battery assembly 100 and the circuit board 60. The bracket 40 can be installed and fixed to prevent the battery 30 from falling off and the connection between the battery 30 and the circuit board 60 from failing. A single bracket 40 and a single installation step can achieve multiple functions, making the overall structure of the terminal device simpler and conducive to reducing costs and increasing efficiency.

[0118] Optionally, the first pressing portion 42 is a plate-shaped structure, and the second pressing portion 43 is a plate-shaped structure. A first recess is formed between the first pressing portion 42 and the frame body 41, and the battery 30 is inserted into the first recess.

[0119] In other embodiments, the battery fixing structure includes multiple brackets 40, and the first pressing portion 42 and the second pressing portion 43 are arranged on different brackets 40. In other words, some brackets 40 include a bracket body 41 and a first pressing portion 42, and some brackets 40 include a bracket body 41 and a second pressing portion 43.

[0120] In one embodiment, referring to Figures 15 to 17The mobile terminal includes a housing, a mounting member 10 and the housing as two separate components, with the mounting member 10 connected to the housing. When assembling the mobile terminal, the battery assembly 100 is mounted on the mounting member 10, which is then mounted on the housing. The mounting member 10, battery assembly 100, and circuit board 60 are all disposed within the housing. The mounting member 10 provides a mounting location for the battery 30 and may also provide a mounting location for the circuit board 60.

[0121] In one embodiment, if Figure 15 、 Figure 16 As shown, the mobile terminal also includes a glass cover plate 600 and a display panel 500, and the shell includes a connected frame 300 and a back shell 400. The mounting member 10 is a mounting plate, the glass cover plate 600 is arranged on the front side of the display panel 500, and the mounting plate is arranged on the back side of the display panel 500. The frame 300 includes a frame and a middle frame connected to the inner side of the frame. The frame is against the edge area on the back side of the glass cover plate 600, and the frame surrounds the outside of the display panel 500. The middle frame is pressed against the side of the mounting plate away from the display panel 500 to fix the mounting plate. The middle area of ​​the mounting plate is exposed, and the battery assembly 100 and the circuit board 60 are installed on the mounting plate to complete the electrical connection between the battery 30 and the circuit board 60. Then the bracket 40 is installed, and finally the back shell 400 is covered to complete the installation of the entire mobile terminal.

[0122] In one embodiment, a fastener 90 is provided between the second mounting portion 21 and the first mounting portion 11 and the second mounting portion 21 and the second mounting portion 11 are detachably connected via the fastener 90 . In other words, the fixing plate 20 and the mounting member 10 are separate structures, and the fixing plate 20 is detachably connected to the mounting member 10 via the fastener 90 .

[0123] Optionally, the fastener 90 is a fastening screw, and the mounting member 10 is a mounting plate. The fastening screw includes a connected screw head and a screw rod. When installing the fixing plate 20, the fastening screw is installed from one side of the fixing plate 20 until the screw rod of the fastening screw is threadedly connected to the mounting plate, thereby locking the fixing plate 20 to the mounting plate, thereby locking the battery assembly 100 to the mounting plate. By passing the fastening screw through the fixing plate 20 and threading it into the mounting plate, a detachable connection between the fixing plate 20 and the mounting plate is achieved, eliminating the need for an additional fastening nut for cooperating with the fastening screw, which helps reduce the overall thickness and facilitates a lightweight design of the terminal device.

[0124] In one embodiment, referring to Figure 6 、 Figure 7The mounting plate includes a plate body and a first mounting portion 11. The first mounting portion 11 is a protruding stud provided on the side of the plate body of the mounting plate close to the fixed plate 20. The second mounting portion 21 of the fixed plate 20 is a plate mounting hole provided on the fixed plate 20. When installing the fixed plate 20, first insert the stud into the plate mounting hole of the fixed plate 20. The stud plays a positioning role for the fixed plate 20. Then, operate the locking fastening screw from the side of the fixed plate 20 away from the mounting plate, and the screw rod of the fastening screw is threadedly connected with the stud. When the mounting plate stud is inserted into the plate mounting hole of the fixed plate 20, the screw rod of the fastening screw passes through the plate mounting hole or the end of the screw rod is located inside the plate mounting hole. In this way, the locking connection length of the fastening screw and the mounting plate stud is guaranteed, the connection strength is guaranteed, and the screw head of the fastening screw is close to the fixed plate 20, locking the fixed plate 20 to the mounting plate.

[0125] It will be appreciated that, in this embodiment, protruding studs are provided on the mounting plate and inserted into the plate mounting holes of the fixing plate 20. The studs of the mounting plate serve as both positioning posts and provide a location for screwing the bracket 40. Furthermore, the first mounting portion 11 of the mounting plate is a protruding stud. This allows the thickness of the main body of the mounting plate to be minimized when assembling the battery assembly 100 and the mounting plate, while maximizing the length of the threaded connection between the fastening screw and the mounting plate to ensure connection strength. This reduces the overall thickness of the assembled mounting plate and battery assembly 100, facilitating its application in lightweight, thin-walled terminal devices.

[0126] Optionally, the stud is provided with a threaded hole, and the screw rod of the fastening screw is inserted into the threaded hole of the stud to be locked with the stud. In other embodiments, the mounting plate stud is provided with an external thread, and the screw rod of the fastening screw is provided with a threaded hole to achieve a threaded connection between the fastening screw and the mounting plate stud.

[0127] In other embodiments, not shown in the figures, the first mounting portion 11 of the mounting plate is a threaded hole provided on the mounting plate, the second mounting portion 21 of the fixing plate 20 is a plate mounting hole provided on the fixing plate 20, and the fastener 90 is a screw. The screw passes through the plate mounting hole and is inserted into the threaded hole of the mounting plate to be threadedly connected with the threaded hole, and the fixing plate 20 is locked to the mounting plate by the screw.

[0128] In other embodiments, the fastener 90 may also include a fastening screw and a fastening nut. The first mounting portion 11 and the second mounting portion 21 are two mounting holes. The fastening screw passes through the two mounting holes of the fixing plate 20 and the mounting plate from one side, and the fastening nut is used to lock the end of the fastening screw on the other side to lock the mounting plate and the fixing plate 20 between the fastening screw head and the fastening nut, so that the battery assembly 100 can be detachably installed on the mounting plate.

[0129] In one embodiment, a battery fixing structure is provided with a bracket 40, which is provided in the manner described in any of the aforementioned embodiments. The second mounting portion 21 of the fixing plate 20 is a plate mounting hole, and the bracket 40 is provided with a bracket mounting hole 4101. The fastener 90 passes through the bracket mounting hole 4101 and the plate mounting hole to connect with the first mounting portion 11 of the mounting plate. The fastener 90 presses the bracket 40 against the fixing plate 20, and the fixing plate 20 is pressed against the mounting plate. The fastener 90 locks the bracket 40 and the fixing plate 20 to the mounting plate. In this way, the installation of the fastener 90 can simultaneously achieve the installation and fixation of the bracket 40 and the battery assembly 100, thereby improving installation efficiency.

[0130] In one embodiment, in order to facilitate the installation of the bracket 40, improve the installation efficiency, and enhance the installation effect, the mounting plate is provided with a first plate positioning structure 12, the fixed plate 20 is provided with a second plate positioning structure 13, and a frame positioning structure 44 is provided on the side of the bracket 40 close to the fixed plate 20. The bracket 40 is positioned and coordinated with the fixed plate 20 and / or the mounting plate through the frame positioning structure 44.

[0131] Optionally, the frame positioning structure 44 is a positioning post, and the first plate positioning structure 12 and the second plate positioning structure 13 are both positioning holes. When installing the bracket 40, the positioning post is inserted into the positioning holes of the two plates to locate the position of the bracket 40. Furthermore, even if the bracket 40 is installed before the battery 30 is installed, the position of the bracket 40 can be reliably positioned. This not only ensures that the bracket 40 and the battery 30 fit well together, but also facilitates the subsequent locking of the bracket 40, the fixing plate 20, and the mounting plate using fasteners 90. In other embodiments, the first plate positioning structure 12 is a positioning post, and the second plate positioning structure 13 and the frame positioning structure 44 are both positioning holes. The positioning post is inserted into the two positioning holes to locate the relative positions of the bracket 40, the fixing plate 20, and the mounting plate.

[0132] In one embodiment, the fixing plate 20 is a metal structure, i.e., the fixing plate 20 is a metal plate; the bracket 40 is a plastic structure, i.e., the bracket 40 is a plastic bracket 40; this helps reduce the overall thickness of the battery fixing structure and facilitates insulation protection of the battery 30. It will be appreciated that using a metal plate as the fixing plate 20 allows the metal plate to be made relatively thin, thereby reducing the overall thickness of the battery fixing structure and facilitating the lightweight and thin design of the terminal device. Furthermore, the first surface of the battery 30 proximal to the fixing plate 20 is a flat surface, and an adhesive layer 50, such as double-sided tape, is provided between the battery 30 and the fixing plate 20. Therefore, even with a metal fixing plate 20, the insulation requirements on the first surface of the battery 30 are met. When the bracket 40 has an L-shaped structure and the L-shaped structure is arranged at the corner of the battery 30 to limit the battery 30, since the insulating outer skin at the corner of the side 31 of the battery 30 is easily damaged compared to the insulating outer skin at the flat first surface of the battery 30, the use of a plastic bracket 40 can achieve insulation coordination between the bracket 40 and the battery 30 while limiting the side 31 of the battery 30, which has high safety.

[0133] In other embodiments, when the internal thickness of the terminal device is more ample, the fixing plate 20 and the bracket 40 can also be made into an integral structure, that is, the fixing plate 20 and the bracket 40 are integrally formed. Optionally, the fixing plate 20 and the bracket 40 are both made of plastic, and the fixing plate 20 and the bracket 40 can be integrally formed by injection molding. When installing the battery 30, the battery 30 can be installed in the installation space defined between the fixing plate 20 and the bracket 40. It is understood that plastic has a certain degree of deformation ability. When installing the battery 30, a tool can be used to slightly deform the bracket 40, allowing the bracket 40 to return to its original shape after the battery 30 is installed and to be able to support the battery 30. Optionally, the fixing plate 20 and the bracket 40 are both made of metal, and the fixing plate 20 and the bracket 40 can be integrally formed by casting or subsequent machining. An additional insulating protective layer 80 such as foam can be provided between the bracket 40 and the battery 30 to provide insulation protection for the battery 30.

[0134] In one embodiment, the battery assembly 100 in the terminal device is assembled as follows:

[0135] Insert the studs of the mounting plate into the plate mounting holes of the fixing plate 20, as shown in FIG. Figure 11 As shown, a first type of bracket 40 is then provided on the side of the fixing plate 20 facing away from the mounting plate. The first type of bracket 40, the fixing plate 20 and the mounting plate are locked and fixed together by screws. At this time, the two first type brackets 40 located at the two corners serve to limit the installation space of the battery 30. Figure 12As shown, the battery 30 is attached to the fixing plate 20 by double-sided tape, and the first electrical connector 72 of the electrical connection line 70 of the battery 30 is plugged into the second electrical connector 73 of the main board of the circuit board 60. Figure 13 、 Figure 14 As shown, the second type of bracket 40 is then mounted on the fixed plate 20 using fasteners 90. The first pressing portion 42 of the second type of bracket 40 blocks the battery 30 on the side facing away from the fixed plate 20, and the second pressing portion 43 blocks the first electrical connector 72 on the side facing away from the circuit board 60. This prevents the battery 30 from loosening or the electrical connector from becoming loose due to vibration during transportation and use, thereby avoiding failure problems caused by loosening. There is no need to specifically provide an additional bracket 40 for pressing the electrical connector, saving costs, simplifying the installation process, and improving installation efficiency. Finally, the back cover 400 is added to form a large-sized, lightweight, and portable learning terminal device.
