[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 This is a structural diagram of a nickel-metal hydride battery 100 with a charging interface provided in an embodiment of the present invention. The nickel-metal hydride battery 100 with a charging interface provided by the present invention has a charging port commonly used in the market, eliminating the need for a dedicated charging socket. It is highly versatile and compatible with mainstream electronic devices such as mobile phones and laptops, meeting users' "one-line-for-multiple-use" needs and improving charging convenience.

[0021] Please refer to the following: Figure 1 and Figure 2 The nickel-metal hydride battery 100 with a charging interface includes a cell assembly 10, an insulating support 20, an elastic connector 30, a protection board 40, a charging interface 50, and a metal sleeve 60.

[0022] One end of the battery cell assembly 10 is provided with a positive terminal post 11. The charging interface 50 is provided on the bottom surface of the protection plate 40, and the opening 501 of the charging interface 50 faces the edge of the protection plate 40. The side of the insulating bracket 20 is provided with a notch 201. The protection plate 40 is provided on the insulating bracket 20 and the charging interface 50 is held in the notch 201. The insulating bracket 20 is also provided with a through hole 202. The elastic connector 30 passes through the through hole 202. One end of the elastic connector 30 is connected to the protection plate 40 and the other end of the elastic connector 30 is connected to the positive terminal post 11. The metal sleeve 60 is provided with a window 601. The metal sleeve 60 covers the protection plate 40 and the insulating bracket 20, and the window 601 is opposite to the opening 501 of the charging interface 50. The protection plate 40 abuts against the metal sleeve 60. The metal sleeve 60 is installed on the outer shell 12 of the battery cell assembly 10.

[0023] Specifically, the protection board 40 can be a circuit board integrating an intelligent management chip. This chip has charging management functions, monitoring voltage, current, and temperature during charging to improve charging safety and efficiency. The protection board 40 can have positive and negative contacts to connect to the positive and negative terminals of the battery cell assembly 10, respectively, to achieve the charging function. The elastic connector 30 connected to the bottom of the protection board 40 can contact and conduct with the positive terminal 11 of the battery cell assembly 10. The protection board 40 also contacts and conducts with the outer shell 12 of the battery cell assembly 10 through a metal sleeve 70. The charging interface 50 can be used to insert a charging cable to connect to a power source, thus forming a charging circuit and enabling the nickel-metal hydride battery to be charged by an external power source. The charging interface 50 can be designed as any commonly used charging port on the market, offering high versatility and eliminating the need for a dedicated charging socket, thus improving charging convenience. Understandably, a conductive sheet can be provided inside the opening 501 of the charging interface 50, electrically connected to the protection board to achieve circuit conduction.

[0024] The protective plate 40 is connected to the positive terminal 11 of the cell assembly 10 by the elastic connector 30, which further improves the conductivity between the circuits and reduces the possibility of loosening and poor contact during use. In addition, the metal sleeve 60 is installed on the outer shell 11 of the cell assembly 10, which further increases the conductivity of the circuit and prevents the possibility of loosening and poor contact or increased impedance when the battery is dropped or impacted. Furthermore, this structure requires fewer related materials and the assembly method is simple, without the need for additional special equipment, which further simplifies the assembly method and improves assembly efficiency.

[0025] Therefore, the nickel-metal hydride battery 100 with a charging interface provided by this utility model has a charging interface 50 disposed on the bottom surface of a protection plate 40, with the opening 501 of the charging interface 50 facing the edge of the protection plate 40. The protection plate 40 is disposed on an insulating bracket 20, and the charging interface 50 is held in the notch 201 of the insulating bracket 20. An elastic connector 30 passes through the through hole 202 of the insulating bracket 20, with one end of the elastic connector 30 connected to the protection plate 40 and the other end connected to the positive terminal 11 of the battery assembly 10. A metal sleeve 60 covers the protection plate 40 and the insulating bracket 20, with the window 601 of the metal sleeve 60 positioned opposite to the opening 501 of the charging interface 50. The plate 40 abuts against the metal sleeve 60, which is installed on the outer shell 12 of the battery cell assembly 10. This allows the protection plate 40 to make contact with the positive terminal 11 of the battery cell assembly 10 through the elastic connector 30. The protection plate 40 also makes contact with the outer shell 12 of the battery cell assembly 10 through the metal sleeve 60. The window 601 of the metal sleeve 60 is opposite to the opening 501 of the charging interface 50. The charging interface 50 can be used to connect a charging cable to a power source for charging. The charging interface 50 can be designed as any type of charging port commonly used in the market, which is highly versatile and does not require a dedicated charging socket. It has charging ecosystem compatibility, improves charging convenience, and has a stable and reliable structure that is easy to implement.

[0026] The battery cell assembly 10 also includes a battery cell 13. Specifically, the outer casing 12 is a cylindrical steel shell, and the outer casing 12 includes a bottom wall 121 and an outer peripheral wall 122 connected to the bottom wall 121 and perpendicular to it. The bottom wall 121 and the outer peripheral wall 122 form a cavity, and the battery cell 13 is housed within the cavity. Specifically, the end of the outer casing 12 away from the bottom wall 121 is open, and the positive terminal 11 of the battery cell 13 extends out of the opening end of the outer casing. A groove 123 is rolled into the outer peripheral wall 122 near the opening end. The rolled groove 123 can more stably fix the battery cell 13 inside the outer casing 12 and prevent the battery cell from shaking. The position of the groove 123 is at the shoulder height of the battery cell assembly 10.

[0027] The battery cell 13 is cylindrical and can be made by winding a positive electrode sheet, a separator, and a negative electrode sheet. The battery cell 13 includes a positive terminal face and a negative terminal face opposite to the positive terminal face. The negative terminal face of the battery cell is welded to the bottom wall of the casing to lead out the negative electrode of the battery, and the positive terminal face of the battery cell is welded to the positive terminal post 11 to lead out the positive electrode of the battery.

[0028] The insulating bracket 20 can be, but is not limited to, a plastic bracket that can provide insulation. Other brackets that can provide insulation are also applicable. The insulating bracket 20 is located at one end of the opening of the housing 12.

[0029] The elastic connector 30 can be configured as a nickel-plated metal spring to ensure the continuity of the circuit, and while ensuring continuity, it also has a certain degree of elasticity, which can play a buffering role and extend the service life of the nickel-metal hydride battery. Understandably, the material of the elastic connector 30 needs to ensure the continuity of the circuit, including but not limited to nickel-plated metal springs, copper-plated metal springs, etc.

[0030] To ensure that the elastic connector 30 can pass smoothly through the insulating bracket 20 and abut against the positive terminal of the battery cell assembly 10, a through hole 202 is provided on the insulating bracket 20 for the elastic connector 30 to pass through. One end of the elastic connector 30 passes through the through hole 202 to reach the positive terminal 11 of the battery cell assembly 10 to complete the conduction. The through hole 202 can also fix the elastic connector 30, so as to facilitate the elastic connector 30 and the positive terminal 11 of the battery cell assembly 10 to complete a stable and reliable contact.

[0031] The protection board 40 has charging management functions and supports the USB-PD fast charging protocol, improving charging efficiency. Specifically, the protection board 40 is provided with positive and negative contacts. The positive contact is electrically connected to the elastic connector 30, and the negative contact is electrically connected to the metal sleeve 60, realizing the conduction of the charging circuit. Preferably, the edge of the protection board 40 is welded to the top edge of the metal sleeve 60. The edge of the negative contact on the front side of the protection board 40 is welded to the edge of the metal sleeve 60 using a welding machine, ensuring that the negative contact is conductive to the negative terminal of the battery. This ensures that the negative terminal of the protection board 40 is in contact with the metal sleeve 60 and prevents poor contact or even open circuit due to loosening or displacement of the protection board 40 during use.

[0032] The charging port 50 can be a Type-C port, a Lightning port, or a Micro-USB port. To expand the charging methods for NiMH batteries, the charging port 50 can be configured as an Android port (i.e., a Micro-USB port), a Type-C port, or a Lightning port. These three ports are all commonly used charging ports, and designing the port according to different charging needs broadens its applicability. Furthermore, for the aforementioned charging port 50, multiple different structures of charging ports can be provided, so that the charging method for NiMH batteries is not limited to any one type of port. Alternatively, a data cable can be led out from the charging port 50 for direct connection to a charging adapter, achieving an aesthetically pleasing result.

[0033] The metal sleeve 60 includes a top wall 61 and a side wall 62 connected to the edge of the top wall 61 and perpendicular to the top wall 61. The top wall 61 and the side wall 62 form a receiving space. The protective plate 40 and the insulating bracket 20 are received in the receiving space. The window 601 is opened on the side wall 62.

[0034] Specifically, to accommodate the charging interface 50, the insulating bracket 20 has a notch 201 that matches the charging interface 50, and the side wall 62 of the metal sleeve 60 has a window 601 that matches the charging interface 50. The notch 201 on the insulating bracket 20 can position the charging interface 50. After the assembly of the insulating bracket 20 and the protective plate 40 is installed onto the metal sleeve 60, the window 601 is perfectly aligned with the charging interface 50, allowing the nickel-metal hydride battery to be charged via a data cable connected to the charging interface 50.

[0035] The top surface of the protective plate 40 is provided with a protruding cap 41, and the top wall 61 of the metal sleeve 60 is provided with a through hole 611. When the metal sleeve 60 covers the protective plate 40 and the insulating bracket 20, the cap 41 passes through the through hole 611.

[0036] Specifically, the top of the protection plate 40 is provided with a cap 41 that can make contact with electrical equipment. By providing a cap 41 on the protection plate 40, contact with electrical equipment can be achieved through the cap 41. The cap 41 protrudes from the top of the protection plate 40, making contact easy and ensuring effective connection.

[0037] Understandably, the cap 41 needs to be insulated from the metal sleeve 60. Therefore, an insulating sealing ring 411 is fitted on one end of the cap 41 near the protective plate 40. After the cap 41 passes through the through hole 611, the metal sleeve 60 at the edge of the through hole 611 abuts against the insulating sealing ring 411. The insulating sealing ring can be a rubber ring, which can simultaneously provide insulation and sealing.

[0038] In this embodiment, the side wall 62 of the metal sleeve 60 extends away from the top wall 61 to the groove 123, and the side wall 62 away from the top wall 61 is fixed in the groove 123 of the outer casing 12. That is, the bottom end of the metal sleeve 60 is installed at the shoulder height of the cell assembly 10, and can be fixed in the groove 123 by closing it with a closing machine. This can effectively prevent loosening and poor contact during use, and can also avoid loosening and poor contact or increased impedance between the metal sleeve 60 and the cell assembly 10 when the battery is dropped or impacted. This simplifies the assembly method and improves assembly efficiency.

[0039] In this embodiment, the battery structure connects the protection plate 40 to the cell assembly 10 via the elastic connector 30, further improving the conductivity between the circuits and reducing the possibility of loosening and poor contact during use. In addition, the metal sleeve 60 is combined with the shoulder height of the cell assembly 10 by the tapering method, further increasing the conductivity of the circuit and preventing the possibility of loosening and poor contact or increased impedance when the battery is dropped or impacted. Furthermore, this structure requires fewer related materials and has a simple assembly method, without the need for additional special equipment, further simplifying the assembly method and improving assembly efficiency.

[0040] Please see Figure 3 In another embodiment, the side wall 62 extends from the top wall 61 to the bottom wall 121. The side wall 62 encloses the outer peripheral wall 122 and the bottom wall 121, that is, the battery assembly 10 is completely installed inside the metal sleeve 60, which effectively prevents loosening and poor contact during use. It can also avoid loosening and poor contact or increased resistance between the metal sleeve 60 and the battery cell assembly 10 when the battery is dropped or impacted. This simplifies the assembly method and improves assembly efficiency.

[0041] In this embodiment, the battery structure connects the protection plate 40 to the cell assembly 10 via the elastic connector 30, further improving the ease of assembly and reducing the possibility of loosening and poor contact during use. The metal sleeve 60 completely encloses the cell assembly 10, and the side wall 62 of the metal part 60 is fixed to the bottom wall 121 of the outer casing 12 by a sealing machine, which enhances structural stability and further protects the cell assembly. In addition, this structure requires fewer related materials and has a simple assembly method, without the need for additional special equipment, further simplifying the assembly method and improving assembly efficiency.

[0042] This utility model provides a nickel-metal hydride battery 100 with a charging interface. Through the design of the charging interface, it achieves fast charging and compatible data transmission, offering strong versatility and compatibility with mainstream devices such as mobile phones and laptops. It eliminates the need for a dedicated charging dock, meeting users' "one-line-for-multiple-uses" needs. By integrating, for example, a Type-C charging interface with a smart management chip, the charging interface enables high-power transmission (supporting USB PD, up to 100W), reversible insertion, and compatible data transmission, solving the core pain points of traditional nickel-metal hydride batteries in terms of compatibility, safety, and efficiency. Simultaneously, combined with a flexible connector structure and the use of highly thermally conductive materials, it achieves a dual breakthrough in protection and heat dissipation, resulting in high structural stability and significant technological advancement and market application value. This application can promote the intelligent upgrade of traditional nickel-metal hydride batteries, meeting modern users' dual needs for convenient charging and high safety. It breaks down the interface barriers between traditional batteries and devices, achieving "one-charge-for-multiple-uses," with a simple structure, easy processing, and a stable and reliable overall structure.

[0043] In summary, the nickel-metal hydride battery 100 with a charging interface provided by this utility model has a charging interface 50 disposed on the bottom surface of a protection plate 40, with the opening 501 of the charging interface 50 facing the edge of the protection plate 40. The protection plate 40 is disposed on an insulating bracket 20, and the charging interface 50 is held in the notch 201 of the insulating bracket 20. An elastic connector 30 passes through the through hole 202 of the insulating bracket 20, with one end of the elastic connector 30 connected to the protection plate 40 and the other end connected to the positive terminal 11 of the battery assembly 10. A metal sleeve 60 covers the protection plate 40 and the insulating bracket 20, with the window 601 of the metal sleeve 60 facing the opening 501 of the charging interface 50. The plate 40 abuts against the metal sleeve 60, which is installed on the outer shell 12 of the battery cell assembly 10. This allows the protection plate 40 to make contact with the positive terminal 11 of the battery cell assembly 10 through the elastic connector 30. The protection plate 40 also makes contact with the outer shell 12 of the battery cell assembly 10 through the metal sleeve 60. The window 601 of the metal sleeve 60 is opposite to the opening 501 of the charging interface 50. The charging interface 50 can be used to connect a charging cable to a power source for charging.
