[0034] 1000. Terminal equipment. Detailed Implementation

[0035] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0036] The following is for reference. Figures 1-5 This invention describes a battery 100 according to an embodiment of the present invention, which is used in a terminal device 1000.

[0037] like Figure 1 , Figure 2 and Figure 5 As shown, the battery 100 according to the present invention includes: a housing 10, a terminal post 20 and a first fixed mounting platform 30. The housing 10 has a first end face 11, the terminal post 20 is disposed on the first end face 11 of the housing 10, and the first fixed mounting platform 30 is disposed on the first end face 11 of the housing 10. The first fixed mounting platform 30 and the terminal post 20 are spaced apart on the first end face 11.

[0038] It is understood that the housing 10, the terminal post 20, and the first fixed mounting platform 30 constitute the main structure of the battery 100. The terminal post 20 can be the positive electrode, and the housing 10 is the negative electrode. The terminal post 20 can effectively transmit the current in the battery 100, thus ensuring the normal operation of the battery 100. The first fixed mounting platform 30 can connect to other components, thereby allowing the housing 10 to connect with other components. A first end face 11 is provided on one side of the housing 10, and the terminal post 20 and the first fixed mounting platform 30 are disposed on the first end face 11. This allows the terminal post 20 and the first fixed mounting platform 30 to be located in the space on one side of the housing 10, thereby increasing the capacity of the cells in the housing 10 without changing the volume of the battery 100, and thus improving the battery 100's range. Moreover, the terminal post 20 and the first fixed mounting platform 30 are arranged at intervals on the first end face 11, thus ensuring the function of the terminal post 20 and the first fixed mounting platform 30, and thus ensuring the function of the battery 100.

[0039] For example, the casing 10 is made of metal, including nickel-plated steel, stainless steel, and titanium alloy. This not only ensures the strength of the casing 10 and effectively protects the battery cells inside, but also ensures the conductivity of the casing 10. The long side of the battery 100 corresponds to the long side of the terminal device 1000. The terminal post 20 and the first fixed mounting platform 30 are set on the long side of the battery 100. This can prevent the terminal device 100 from being damaged by impact due to insufficient contact area with the ground when it falls, thereby extending the service life of the battery 100 and improving its safety.

[0040] Therefore, by setting the terminal post 20 and the first fixed mounting platform 30 on the first end face 11 of the housing 10, the terminal post 20 and the first fixed mounting platform 30 can share a space distance of the housing 10, thereby improving the space utilization of the battery 100. Moreover, the terminal post 20 and the first fixed mounting platform 30 are spaced apart on the first end face 11, thereby ensuring the respective functions of the terminal post 20 and the first fixed mounting platform 30. This not only expands the capacity of the battery 100, but also increases the energy density of the battery 100, thereby improving the battery life of the terminal device 1000.

[0041] In particular, such as Figure 1 , Figure 2 and Figure 5 As shown, the first fixed mounting platform 30 and the terminal post 20 are spaced apart along the length of the first end face 11. That is, the housing 10 is divided into a long side and a short side, and the first end face 11 is located at one of the short sides of the housing 10. The terminal post 20 and the first fixed mounting platform 30 are disposed on the first end face 11. This allows the terminal post 20 and the first fixed mounting platform 30 to protrude relative to the short side of the housing 10. Moreover, the terminal post 20 and the first fixed mounting platform 30 are spaced apart along the length of the short side of the housing 10, thereby ensuring the respective functions of the terminal post 20 and the first fixed mounting platform 30, and thus ensuring the normal operation of the battery 100 and the energy density of the battery 100.

[0042] Optionally, such as Figure 2 As shown, the minimum distance from the center of the pole post 20 to the center of the first end face 11 is a, and the minimum distance from the center of the first fixed mounting platform 30 to the center of the first end face 11 is b. a and b satisfy the relationship: a > b.

[0043] It is understandable that the relationship between the minimum distance from the center of the pole post 20 to the center of the first end face 11 and the minimum distance from the center of the first fixed mounting platform 30 to the center of the first end face 11 should be within a reasonable range. If the minimum distance from the center of the pole post 20 to the center of the first end face 11 is less than the minimum distance from the center of the first fixed mounting platform 30 to the center of the first end face 11, the first fixed mounting platform 30 will be located at the edge of the length direction of the first end face 11, and the pole post 20 will be close to the center of the first end face 11, or the pole post 20 will coincide with the first fixed mounting platform 30. In this case, the pole post 20 will not be easy to connect with other components, and the first fixed mounting platform 30 will not be easy to connect with other components, resulting in a poor layout of the battery 100 and waste.

[0044] If the minimum distance from the center of the terminal post 20 to the center of the first end face 11 is equal to the minimum distance from the center of the first fixed mounting platform 30 to the center of the first end face 11, the terminal post 20 will coincide with the first fixed mounting platform 30. As a result, the terminal post 20 will not be easy to connect with other components, and the first fixed mounting platform 30 will not be easy to connect with other components, resulting in a poor layout and waste of the battery 100.

[0045] If the minimum distance from the center of pole post 20 to the center of the first end face 11 is greater than the minimum distance from the center of the first fixed mounting platform 30 to the center of the first end face 11, the pole post 20 can be brought closer to the edge of the first end face 11 and the first fixed mounting platform 30 can be brought closer to the center of the first end face 11, so that the pole post 20 and the first fixed mounting platform 30 do not affect each other, thereby ensuring the function of the pole post 20 and the first fixed mounting platform 30.

[0046] In particular, such as Figure 1 , Figure 2 and Figure 5 As shown, there is one first fixed mounting platform 30 or multiple first fixed mounting platforms 30, and multiple first fixed mounting platforms 30 and pole posts 20 are spaced apart along the length of the first end face 11.

[0047] In other words, if there is only one first fixed mounting platform 30, its length extends along the length direction of the first end face, and the first fixed mounting platform 30 is located in the center of the first end face 11, the stability of the connection between the housing 10 and other components can be guaranteed. If there are multiple first fixed mounting platforms 30, the multiple first fixed mounting platforms 30 are evenly spaced along the length direction of the first end face 11, and the multiple first fixed mounting platforms 30 are located in the middle relative to the first end face 11, the stability of the connection between the housing 10 and other components can be guaranteed.

[0048] The pole post 20 is positioned relative to any one of the plurality of first fixed mounting platforms 30 near the edge of the first end face 11 in the length direction. This ensures that the pole post 20 and the first fixed mounting platform 30 do not interfere with each other, thereby guaranteeing the functionality of the pole post 20 and the first fixed mounting platform 30.

[0049] For example, the first fixed mounting platform 30 is welded or bonded to the housing 10. Welding connections include laser welding, resistance welding and brazing. Resistance welding is a commonly used welding method. In this welding method, the fusion point is the contact point between the fixed mounting platform and the side wall towards the long side of the housing 10. Brazing welding needs to be done when there are no battery cells in the housing 10, so as to avoid overheating during brazing and damage to the battery cells.

[0050] In addition, such as Figure 1 , Figure 2 and Figure 5 As shown, the battery 100 also includes: a liquid filling sealing cap 40, the housing 10 is provided with a liquid filling port, the liquid filling sealing cap 40 is disposed at the liquid filling port, and the liquid filling sealing cap 40, the first fixed mounting platform 30 and the terminal post 20 are spaced apart in the length direction of the first end face 11.

[0051] It is understandable that an electrolyte inlet is provided on the first end face 11 of the housing 10. This allows the operator to operate only one space when performing electrolyte injection, connection of the terminal post 20, or connection of the first fixed mounting platform 30, thereby optimizing the spatial arrangement of the battery 100. The electrolyte sealing cap 40 is located at the electrolyte inlet. After the operator injects the electrolyte through the electrolyte inlet, the electrolyte sealing cap 40 seals the electrolyte inlet, thereby preventing electrolyte leakage and ensuring the safety of the battery 100.

[0052] The liquid filling sealing cap 40, the terminal post 20, and the first fixed mounting platform 30 are disposed on the first end face 11. This allows the liquid filling sealing cap 40, the terminal post 20, and the first fixed mounting platform 30 to be located in the space on one side of the housing 10, thereby increasing the capacity of the cells in the housing 10 without changing the volume of the battery 100, and thus improving the battery 100's range. Moreover, the liquid filling sealing cap 40, the terminal post 20, and the first fixed mounting platform 30 are arranged at intervals on the first end face 11, which ensures the functionality of the liquid filling sealing cap 40, the terminal post 20, and the first fixed mounting platform 30, thereby ensuring the functionality of the battery 100 and ensuring the energy density of the battery 100.

[0053] In particular, such as Figure 1 , Figure 2 and Figure 5 As shown, there are multiple first fixed mounting platforms 30, and the liquid injection sealing cap 40 is located between two adjacent first fixed mounting platforms 30 along the length direction of the first end face 11.

[0054] In other words, multiple first fixed mounting platforms 30 are evenly spaced along the length of the first end face 11, which ensures the stability of the connection between the first fixed mounting platforms 30 and other components. Moreover, the multiple first fixed mounting platforms 30 are centrally located on the first end face 11, with the liquid injection port located between two of the first fixed mounting platforms 30 and the liquid injection sealing cap 40 also located between two of the first fixed mounting platforms 30. This ensures that the liquid injection sealing cap 40 does not affect the function of the first fixed mounting platform 30, thereby ensuring the connection between the first fixed mounting platform 30 and other components, and thus ensuring the integrity of the battery 100.

[0055] In addition, such as Figures 1-4 As shown, the battery 100 also includes a protection component 50, which is connected to the terminal 20. It is understood that the connection between the protection component 50 and the terminal 20 allows the protection component 50 to protect the terminal 20, thereby ensuring the function of the terminal 20 and extending its service life, thus improving the lifespan and safety of the battery 100.

[0056] Among them, such as Figures 1-4 As shown, the protection component 50 includes a circuit board 51 and a protection module 52. One end of the circuit board 51 is connected to the pole post 20, and the protection module 52 is disposed at the other end of the circuit board 51.

[0057] In other words, the circuit board 51 and the protection module 52 constitute the main structure of the protection component 50. One end of the circuit board 51 is electrically connected to the terminal 20, and the other end of the circuit board 51 is equipped with the protection module 52. When the battery 100 is working, the circuit board 51 can transmit the current information of the terminal 20 to the protection module 52. The protection module 52 analyzes the information and then determines whether the battery 100 should continue to operate, thereby protecting the battery 100 from damage and extending the service life of the battery 100.

[0058] For example, the protection module 52 is disposed on one side of the circuit board 51, and the protection module 52 is formed into a rectangle with a length-to-width ratio close to 1. This not only allows the current to pass through the protection module 52 in a longer and shorter path, but also makes the space occupied by the protection module 52 more compact, thereby increasing the capacity of the battery cell and improving the energy density of the battery 100, which in turn can further improve the battery 100's range.

[0059] The protection module 52 includes a protection integrated circuit and a protection switch. The protection integrated circuit is electrically connected to the circuit board 51, and the protection switch is electrically connected between the protection integrated circuit and the circuit board 51.

[0060] It is understandable that the protection integrated circuit and the protection switch constitute the main structure of the protection module 52. The protection integrated circuit and the circuit board 51 are electrically connected, so that the current of the battery cell flows into the circuit board 51 through the terminal 20, and then into the protection integrated circuit through the circuit board 51. The protection switch is connected to the protection integrated circuit and the circuit board 51, so that the protection switch can connect or disconnect the connection between the protection integrated circuit and the circuit board 51. Moreover, the protection switch detects the voltage and current of the battery 100, thereby ensuring that the voltage and current of the battery 100 are within the protection threshold. If the protection threshold is exceeded, the low output of the battery 100 will disconnect the protection switch, cut off the connection circuit between the protection integrated circuit and the circuit board 51, and the battery 100 will stop charging or discharging, thereby protecting the battery 100 from damage and extending the service life of the battery 100.

[0061] In addition, such as Figure 3 and Figure 4 As shown, the circuit board 51 is a flexible circuit board 51 and includes: a first plate portion 511 and a second plate portion 512. The first plate portion 511 extends along the length direction of the first end face 11 and one end is connected to the pole post 20. One end of the second plate portion 512 is connected to the other end of the first plate portion 511 and is perpendicular to the first plate portion 511. The protection module 52 is disposed at the other end of the second plate portion 512.

[0062] In other words, a flexible circuit board 51 is selected for the circuit board 51, which makes the circuit board 51 flexible, lightweight, small in size, with high-density wiring and durable. The first board portion 511 and the second board portion 512 constitute the main structure of the circuit board 51. The first board portion 511 extends in the length direction relative to the first end face 11. One end of the first board portion 511 is electrically connected to the terminal 20, and the other end is connected to the second board portion 512. The first board portion 511 and the second board portion 512 are perpendicular to each other, so that the first board portion 511 and the second board portion 512 form an "L" shape. It also ensures that the second board portion 512 does not affect the normal operation of the terminal 20. Moreover, the protection module 52 is located at the end of the second board portion 512 away from the first board portion 511. This allows the protection module 52 to fully analyze the current status of the circuit board 51 and also ensures that the protection module 52 does not affect the normal operation of the terminal 20, thereby protecting the battery 100 from damage and extending the service life of the battery 100.

[0063] In addition, such as Figures 2-4 As shown, a through hole 513 is opened at one end of the circuit board 51; the protection board assembly also includes a metal part 53, which is disposed in the through hole 513 and connected to the pole post 20.

[0064] Understandably, a through hole 513 is provided at the end of the circuit board 51 near the electrode post 20. The through hole 513 can limit the movement of the metal component 53, and the through hole 513 corresponds to the electrode post 20, which facilitates the soldering connection between the metal component 53 and the electrode post 20, thereby enabling an electrical connection between the circuit board 51 and the electrode post 20. For example, resistance welding or laser welding can be used between the metal component 53 and the electrode post 20 to ensure the stability between them.

[0065] For example, the metal part 53 is bonded to one side of the housing 10 using adhesive 90, which makes the connection between the metal part 53 and the housing 10 more secure.

[0066] In addition, such as Figure 2 As shown, the battery 100 also includes a cover 60, which is disposed on one side of the circuit board 51 away from the housing 10.

[0067] In other words, the cover 60 is located at the end of the circuit board 51 near the terminal post 20, and the cover 60 is located on the side of the circuit board 51 away from the first end face 11. This allows the cover 60 to protect the terminal post 20, thereby extending the service life of the terminal post 20 and ensuring the performance of the battery 100. The cover 60, the liquid filling sealing cap 40, the terminal post 20, and the first fixed mounting platform 30 are all located on the first end face 11. This allows the cover 60, the liquid filling sealing cap 40, the terminal post 20, and the first fixed mounting platform 30 to be located in the space on one side of the housing 10, thereby increasing the capacity of the cells in the housing 10 without changing the volume of the battery 100, and thus improving the battery 100's range.

[0068] In addition, such as Figure 3 As shown, the protection board assembly also includes a connector 54, which is disposed at the other end of the circuit board 51. The connector 54 and the protection module 52 are located on opposite sides of the other end of the circuit board 51 in the thickness direction.

[0069] It is understood that the connector 54 is located at the end of the circuit board 51 away from the terminal post 20, and the connector 54 and the protection module 52 are arranged opposite to each other, that is, the connector 54 and the protection module 52 are arranged opposite to each other in the thickness direction of the circuit board 51. The connector 54 can communicate with other electrical connectors outside the battery 100, thereby expanding the application scenarios of the battery 100.

[0070] In addition, such as Figure 1 , Figure 2 and Figure 5 As shown, the battery 100 also includes a second fixed mounting platform 70. The housing 10 has a second end face 12. The first end face 11 and the second end face 12 are disposed opposite to the housing 10. The second fixed mounting platform 70 is disposed on the second end face 12 of the housing 10.

[0071] In other words, the second end face 12 on the housing 10 corresponds to the first end face 11, and the second fixed mounting platform 70 is disposed on the second end face 12. This allows the first fixed mounting platform 30 and the second fixed mounting platform 70 to be disposed on both sides of the housing 10, and the first fixed mounting platform 30 and the second fixed mounting platform 70 to be connected to other components, thereby maintaining a balance between the connection between the housing 10 and other components, and thus ensuring the stability of the battery 100.

[0072] In addition, as shown in the figure, the battery 100 also includes an insulating member 80, which is disposed between the terminal 20 and the housing 10, and the terminal 20 and the housing 10 have opposite polarities.

[0073] Understandably, the insulating component 80 is located between the terminal 20 and the casing 10, with the terminal 20 being the positive electrode and the casing 10 being the negative electrode. This isolates the terminal 20 from the casing 10, ensuring the normal operation of the battery 100. For example, the insulating component 80 can be made of organic or inorganic materials. Organic materials could be polypropylene perfluoroalkoxy polymers or polyphenylene sulfide, while inorganic materials could be ceramics or glass, thus ensuring complete isolation between the terminal 20 and the casing 10.

[0074] The terminal device 1000 according to this utility model includes: the battery 100 of the above embodiments. By setting the terminal post 20 and the first fixed mounting platform 30 on the first end face 11 of the housing 10, the terminal post 20 and the first fixed mounting platform 30 can share a space distance of the housing 10, thereby improving the space utilization of the battery 100. Moreover, the terminal post 20 and the first fixed mounting platform 30 are spaced apart on the first end face 11, thereby ensuring the respective functions of the terminal post 20 and the first fixed mounting platform 30. This not only increases the capacity of the battery 100, but also improves the energy density of the battery 100, thereby improving the battery life of the terminal device 1000.
