Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically a general-purpose battery. Background Technology

[0002] With the development of industry and technology, the demand for high-voltage power supplies is increasing. Certain industrial equipment, large instruments, and some high-performance electronic devices require higher voltages to meet their power demands. The emergence of universal batteries is a response to this need.

[0003] However, existing universal batteries still have some problems: the traditional battery interface and external plug connection structure may lack flexibility. For example, when the plug is inserted, if the connecting parts cannot adaptively adjust according to the insertion, two situations can easily occur. On the one hand, if the connecting parts apply too much pressure to the plug, it may cause physical damage to the plug or the connected parts during insertion and removal, affecting their service life and normal use; on the other hand, if the pressure is too low, good electrical contact between the plug and the connecting parts cannot be guaranteed, thus causing poor contact problems.

[0004] Therefore, there is an urgent need for a universal battery to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of this utility model is to provide a universal battery to solve the problem that the connecting parts cannot adaptively adjust according to the insertion of the plug.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a universal battery, comprising:

[0007] case;

[0008] An electrical component, built into the housing, is used for the conversion and storage of electrical energy;

[0009] The interface includes a mounting base and a connecting clip. The mounting base is built into the interior of the housing, and the connecting clip is inserted into the mounting base. The upper end of the connecting clip is a conductive contact portion for connecting with an external plug, and the lower end of the connecting clip is a connecting pin for electrical connection with an electrical component.

[0010] The auxiliary component includes a connecting pin and an elastic element. Both the connecting pin and the connecting clip are conductive. The tip of the connecting pin is slidably inserted from the mounting base into the conductive contact portion of the connecting clip. The fixed end of the elastic element is fixed on the mounting base, and the elastic end of the elastic element abuts against the tail end of the connecting pin.

[0011] As a preferred embodiment of a general-purpose battery, the elastic element is composed of symmetrically arranged connecting pieces. One end of the symmetrical connecting piece extends outward, and the other end of the symmetrical connecting piece closes inward. The tail end of the connecting pin extends into the outwardly extending end of the symmetrical connecting piece, and the tail end of the connecting pin abuts against the inwardly closing end of the connecting piece.

[0012] As a preferred embodiment of a general-purpose battery, the electrical assembly includes a battery pack consisting of a plurality of main batteries and side batteries. The plurality of main batteries are arranged in a rectangular array, and the side batteries are symmetrically arranged at the opposite corners of the rectangular array.

[0013] As a preferred embodiment of a universal battery, it also includes a connecting frame, which is built into the interior of the housing, and the battery pack is installed within the connecting frame.

[0014] As a preferred embodiment of a universal battery, the connecting frame includes a first frame, a second frame, and fasteners. The first frame and the second frame are detachably connected and fixed within the housing, and the fasteners are connected between the first frame and the second frame.

[0015] As a preferred option for a general-purpose battery, the electrical assembly also includes a circuit protection component disposed within the housing. The circuit protection component is used to promptly disconnect the circuit in the event of an overload or short circuit, thereby ensuring the safety of the battery and related electrical equipment.

[0016] As a preferred embodiment of a general-purpose battery, the circuit protection assembly includes a microswitch and a load. The common terminal of the microswitch is electrically connected to the battery pack, and the trigger pin of the microswitch is electrically connected to the load.

[0017] As a preferred embodiment of a general-purpose battery, the electrical component further includes a display component disposed within the housing, the display component being used to display the battery's charge level.

[0018] As a preferred embodiment of a general-purpose battery, it also includes a limiting component disposed on the housing in conjunction with the interface, the limiting component being used for a stable electrical connection with an external device.

[0019] As a preferred embodiment of a general-purpose battery, the limiting component includes a groove and protrusions. The groove is recessed into the top surface of the housing, and the protrusions are symmetrically arranged at the top of the groove, with each protrusion extending along a symmetrical protrusion direction.

[0020] The beneficial effects of this invention are as follows: Both the connecting pin and the connecting clip are made of conductive material. The tip of the connecting pin can slide into the conductive contact portion of the connecting clip from the mounting base. Simultaneously, the elastic end of the elastic element presses tightly against the tail end of the connecting pin. When the conductive contact portion is plugged into an external plug, the tip of the connecting pin can adaptively retract to the appropriate position according to the plug insertion under the action of the elastic element. This ensures that the contact pressure between the connecting pin and the plug is stably maintained within a suitable range, effectively avoiding the risk of damage to the plug or connecting pin due to excessive pressure, and preventing poor contact caused by insufficient pressure. This enhances the connection performance when plugged into an external plug, significantly improving the overall conductivity and stability of the battery interface. Even under complex operating conditions such as vibration and frequent plugging / unplugging, reliable power transmission can be ensured, improving the practicality and reliability of general-purpose batteries in the field of electronic device power supply.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0030] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0032] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0033] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0034] In one embodiment of this utility model, such as Figure 1-7 As shown, a universal battery is provided, including: a housing 1, an electrical component 2, an interface 13, and an auxiliary component 16; the electrical component 2 is built into the housing 1 and is used for electrical energy conversion and storage; the interface 13 includes a mounting base 14 and a connecting clip 15, the mounting base 14 is built into the housing 1, the connecting clip 15 is inserted into the mounting base 14, the upper end of the connecting clip 15 is a conductive contact portion for connecting with an external plug, and the lower end of the connecting clip 15 is a connecting pin for electrical connection with the electrical component 2; the auxiliary component 16 includes a connecting pin 17 and an elastic element 18, both the connecting pin 17 and the connecting clip 15 are conductive, the tip of the connecting pin 17 is slidably inserted from the mounting base 14 into the conductive contact portion of the connecting clip 15, the fixed end of the elastic element 18 is fixed to the mounting base 14, and the elastic end of the elastic element 18 abuts against the tail end of the connecting pin 17.

[0035] The universal battery provided by this utility model uses conductive materials for both the connecting pin 17 and the connecting clip 15. The tip of the connecting pin 17 can slide from the mounting base 14 into the conductive contact portion of the connecting clip 15, while the elastic end of the elastic member 18 presses tightly against the tail end of the connecting pin 17. When the conductive contact portion is plugged into an external plug, the tip of the connecting pin 17 can adaptively retract to the appropriate position according to the plug insertion under the action of the elastic member 18. This ensures that the contact pressure between the connecting pin 17 and the plug is stably maintained within a suitable range, effectively avoiding the risk of damage to the plug or connecting pin 17 due to excessive pressure, and preventing poor contact problems caused by insufficient pressure. This enhances the connection performance when plugged into an external plug, effectively reduces contact resistance, reduces power loss and heat generation during power transmission, and significantly improves the overall conductivity and stability of the battery interface 13. Even under complex operating conditions such as vibration and frequent plugging and unplugging, reliable power transmission can be ensured, improving the practicality and reliability of the universal battery in the field of electronic device power supply.

[0036] Specifically, the elastic element 18 is composed of symmetrically arranged connecting pieces 24. One end of the symmetrical connecting piece 24 extends outward, and the other end of the symmetrical connecting piece 24 closes inward. The tail end of the connecting pin 17 extends into the outwardly extending end of the symmetrical connecting piece 24, and the tail end of the connecting pin 17 abuts against the inwardly closing end of the connecting piece 24. In this embodiment, the connecting piece 24 is made of an elastic material, such as metal or related materials.

[0037] The outward-extending end of the connecting piece 24 facilitates the smooth insertion of the connecting pin 17, while the inward-closing end tightly abuts against the tail end of the connecting pin 17, effectively fixing the position of the connecting pin 17 and preventing it from easily coming out or shifting. When the external plug is inserted into the conductive contact, it applies an inward pushing force to the connecting pin 17, causing the connecting pin 17 to slightly open the inward-closing end of the elastic element 18. The connecting piece 24 then reacts by pushing the connecting pin 17 tightly to ensure a secure connection with the external plug.

[0038] In other embodiments, the elastic element 18 may be a spring structure.

[0039] Preferably, the auxiliary component 16 further includes a locking block 20, a fixing plate 21, and a guide rod 22. The fixing plate 21 is mounted on the mounting base 14. The fixing plate 21 and the mounting base 14 can be integrally molded from the same plastic material. A gap 23 is reserved between the fixing plate 21 and the mounting base 14 for the movement of the connecting pin 17. The elastic element 18 is fixed on the fixing plate 21. The locking block 20 is fixed to the tail of the connecting pin 17. The diameter / width of the locking block 20 is larger than the diameter of the connecting pin 17. The locking block 20 is locked within the gap 23. The guide rod 22 is movably mounted on the fixing plate. The guide rod 22 passes through the fixing plate into the gap 23 and connects with the locking block 20.

[0040] Through the coordinated action of the locking block 20, the fixing plate 21, and the guide rod 22, the connecting pin 17 achieves stable movement and precise positioning within a specific range. The locking block 20 effectively limits the displacement range of the connecting pin 17, and its design, with a diameter larger than that of the connecting pin 17, ensures that the connecting pin 17 will not disengage from the predetermined track. The fixing plate 21 not only provides a stable mounting element for the elastic element 18, but its integral molding with the mounting base 14 and the reserved movement interval 23 for the connecting pin 17 ensures that the connecting pin 17 can smoothly extend and retract under force. The guide rod 22 plays a precise guiding role during the extension and retraction of the connecting pin 17, ensuring that the connecting pin 17 always moves along the predetermined direction, avoiding deviation or wobbling, thereby further improving the stability and reliability of the connection. This ensures that the entire connection system can operate efficiently and stably under various working conditions, providing solid structural support for a good connection between the battery interface 13 and the external plug.

[0041] The universal battery also includes a limiting component 25, disposed on the housing 1 and the interface 13. The limiting component 25 is used for a stable electrical connection with an external device. Specifically, the limiting component 25 includes a groove 26 and protrusions 27. The groove 26 is recessed into the top surface of the housing 1, and the protrusions 27 are symmetrically arranged at the top of the groove 26, with each protrusion 27 extending along a symmetrical protrusion direction. This provides a stable guiding path for the connection process between the interface 13 and the external plug, effectively preventing misalignment or offset during connection and ensuring the accuracy and reliability of the electrical connection.

[0042] Preferably, the electrical component 2 further includes a display component 28, which is disposed within the housing 1. The display component 28 is used to display the battery's charge level. Based on the received data, the display component 28 uses its built-in display driver circuit and display screen to clearly display the current battery charge status in the form of numbers, icons, or bar charts, allowing the user to know the remaining battery charge at a glance. This greatly improves the convenience for the user in monitoring battery usage, thereby optimizing the user experience and enhancing the practicality and reliability of the universal battery.

[0043] Preferably, the electrical component 2 includes a battery pack 6, which consists of a plurality of main batteries 7 and side batteries 8. The plurality of main batteries 7 are arranged in a rectangular array, and the side batteries 8 are symmetrically arranged at the diagonal sides of the rectangular array. By setting the side batteries 8, on the one hand, the battery capacity can be further expanded within a limited space, enhancing the overall battery life of the battery pack 6; on the other hand, it helps to balance the charge distribution inside the battery pack 6, reducing the potential performance degradation or safety hazards caused by uneven local charge, ensuring that the battery pack 6 can output power stably and efficiently under different operating conditions, thereby improving the applicability and competitiveness of general-purpose batteries in various electronic devices.

[0044] Preferably, the electrical component 2 further includes a circuit protection component 3, disposed within the housing 1. The circuit protection component 3 is used to promptly disconnect the circuit in the event of an overload or short circuit, thereby ensuring the safety of the battery and related electrical equipment. Specifically, the circuit protection component 3 includes a micro switch 4 and a load 5. The common terminal of the micro switch 4 is electrically connected to the battery pack 6, and the trigger pin of the micro switch 4 is electrically connected to the load 5.

[0045] Under normal circumstances, the circuit operates normally, with microswitch 4 in the closed state. Current can flow smoothly from battery pack 6 through microswitch 4 to load 5, ensuring the normal operation of electrical equipment. In case of a fault, since the common terminal of microswitch 4 is connected to battery pack 6, excessive current will affect the sensitive element inside microswitch 4, triggering its trigger pin to actuate. This causes microswitch 4 to quickly disconnect from the electrical connection with load 5, thereby cutting off the entire circuit. This effectively prevents irreversible damage to battery pack 6 caused by excessive current, such as preventing dangerous situations like battery overheating, bulging, or even explosion. Moreover, this connection method between microswitch 4 and load 5 is simple and reliable, with high sensitivity and fast response characteristics. It can detect abnormal current and cut off the circuit in a very short time, greatly improving the safety and reliability of general-purpose batteries in various complex electrical environments, providing a solid protective barrier for users' life and property safety and the normal use of electronic equipment.

[0046] Preferably, the electrical component 2 also includes a circuit board 29, and the display component 28, battery pack 6, and circuit protection component 3 can be electrically connected to the circuit board 29 to complete functions such as signal transmission, power distribution and regulation, and data interaction.

[0047] The universal battery also includes a connecting frame 9, which is built into the housing 1, and the battery pack 6 is installed in the connecting frame 9. Specifically, the connecting frame 9 includes a first frame 10, a second frame 11, and a fastener 12. The first frame 10 and the second frame 11 are detachably connected and fixed to the housing 1, and the housing 1 can be fixed to the first frame 10 and the second frame 11 by screws. The fastener 12 is connected between the first frame 10 and the second frame 11, and the fixing element can be a screw.

[0048] The first frame 10 and the second frame 11 are detachably connected to the housing 1 using screws. This not only facilitates the installation of the connecting frame 9 and the battery pack 6 during production and assembly, improving production efficiency, but also allows for easy removal of the battery pack 6 from the housing 1 when it needs repair, replacement, or upgrade. The fasteners 12 (such as screws) connecting the first frame 10 and the second frame 11 further enhance the overall strength and stability of the connecting frame 9, ensuring that the battery pack 6 is firmly fixed within the housing 1. Even when the equipment is subjected to external forces such as vibration, shaking, or collision, it effectively prevents the battery pack 6 from shifting or loosening. This ensures that the electrical connection between the battery pack 6 and other electrical components 2 remains stable and reliable, avoiding problems such as poor contact or even open circuits caused by battery pack 6 shaking. This significantly improves the reliability and safety of the universal battery in various complex operating environments, extends the battery's lifespan, and reduces maintenance costs.
