Description

Technical Field

[0001] This application belongs to the field of battery technology, and in particular relates to a battery connector and a battery. Background Technology

[0002] Existing battery discharge port structures typically employ an integrated or fixed wired discharge port socket. During installation, the operator must first place the waterproof ring onto the wired discharge port socket, and then use screws to directly tighten and secure it to the battery pack casing.

[0003] Because the discharge port socket is a component that is frequently plugged and unplugged from the external connector, it is prone to arcing at the contact interface during long-term use due to wear from plugging and unplugging, poor contact, or sudden high current surges. The high temperature generated by arcing often burns the internal terminals and surrounding plastic structure of the discharge port socket, causing damage to the entire socket. Once such a failure occurs, since the discharge port socket is directly fixed to the battery pack casing with screws, and its tail is usually connected to a high-voltage harness, maintenance personnel need to disassemble the entire discharge port socket and its connecting wires. This is extremely inconvenient due to limited operating space. More importantly, this repair method is not only time-consuming and labor-intensive, but may also damage the connecting wires or introduce new safety hazards, resulting in high repair costs. Summary of the Invention

[0004] The purpose of this application is to provide a battery connector and a battery, which aims to solve the problems of difficult and costly repair after the battery discharge port is damaged in the traditional technology.

[0005] The first aspect of this application provides a battery connector that passes through the outer casing of a battery, the outer casing being used to install a battery energy storage device, and the outer casing being provided with an electrical connection port. The battery connector includes: A first discharge socket is disposed outside the housing and detachably mounted on the electrical connection port. The first discharge socket is used for electrical connection with the device to be powered. The second discharge holder is disposed inside the housing and is detachably installed on the electrical connection port. The second discharge holder is electrically connected to the battery energy storage device. In the case where the first discharge base and the second discharge base are installed on the electrical connection port, the first discharge base and the second discharge base are electrically connected by plugging into the electrical connection port, and the housings of the first discharge base and the second discharge base are insulated from each other.

[0006] In some embodiments of this application, the battery connector further includes a waterproof gasket, which is pressed between the first discharge socket and the housing to seal the first discharge socket and the housing.

[0007] In some embodiments of this application, at least one side of the waterproof gasket is provided with a waterproof protrusion, which is arranged around the waterproof gasket in an annular direction.

[0008] In some embodiments of this application, the number of waterproof protrusions is two, and the two waterproof protrusions are arranged concentrically around each other.

[0009] In some embodiments of this application, a first protrusion is provided on the side of the first discharge base near the outer shell, and a first connection terminal for electrical connection with the second discharge base is provided on the first protrusion. A blocking platform is provided at least one side of the first protrusion at a distance, and at least a portion of the waterproof gasket is engaged between the first protrusion and the blocking platform.

[0010] In some embodiments of this application, the waterproof gasket is provided with an avoidance notch, which is adapted to the blocking platform.

[0011] In some embodiments of this application, the first protrusion is provided with a foolproof protrusion structure, and the second discharge base is provided with a foolproof notch, the foolproof notch being adapted to the foolproof protrusion structure.

[0012] In some embodiments of this application, the outer casing is provided with a mounting groove, the electrical connection port is disposed at the bottom of the mounting groove, and the mounting groove is used to be fitted with the first discharge base. The bottom of the mounting groove is provided with a first threaded hole, and the first discharge base is provided with a second threaded hole. The second threaded hole is provided corresponding to the first threaded hole, and can be screwed to the first threaded hole and the second threaded hole by bolts to install the first discharge base onto the mounting groove.

[0013] In some embodiments of this application, the second discharge base is provided with a third threaded hole, and the inner wall of the housing is provided with a stud. The third threaded hole is correspondingly provided with the stud, and the third threaded hole and the stud can be fixed by bolts to install the second discharge base onto the inner wall of the housing.

[0014] In some embodiments of this application, the second discharge base is further provided with a positioning hole, and the inner wall of the outer shell is provided with a positioning post. The positioning hole and the positioning post are inserted and adapted to pre-position the second discharge base and the outer shell.

[0015] A second aspect of the embodiments of this application also provides a battery, the battery including a housing, a battery energy storage device and a battery connector as described above, the battery energy storage device being disposed inside the housing and electrically connected to a device to be powered through the battery connector on the housing; The housing includes a top cover, and the battery connector is disposed on the top cover.

[0016] The beneficial effects of this application are as follows: In the battery connector and battery of this application, the battery connector is disposed on the outer casing of the battery, the outer casing is used to install the battery energy storage device, and the outer casing is provided with an electrical connection port; the battery connector includes a first discharge socket and a second discharge socket; the second discharge socket is disposed inside the outer casing and is detachably installed on the electrical connection port, and the second discharge socket is electrically connected to the battery energy storage device; the first discharge socket is disposed outside the outer casing and is detachably installed on the electrical connection port, and the first discharge socket is used to electrically connect to the device to be powered; wherein, when the first discharge socket and the second discharge socket are installed on the electrical connection port, the first discharge socket and the second discharge socket are electrically connected by plugging into the electrical connection port, and the shells of the first discharge socket and the shells of the second discharge socket are insulated. The traditional integrated discharge port structure is split into two independent and separable pluggable parts: a second discharge socket located inside the outer casing and a first discharge socket located outside the outer casing. When the first discharge socket outside the outer casing is damaged due to electrical arcing or wear caused by frequent plugging and unplugging, the second discharge socket remains intact because it is located inside the outer casing and the two casings are insulated from each other. Furthermore, since the first and second discharge sockets are electrically connected via a plug-in connection, maintenance personnel do not need to manipulate the high-voltage wiring harness inside the battery casing. They can simply remove the damaged first discharge socket from the outside of the battery casing and replace it with a new one. The maintenance process is simple and quick, greatly reducing maintenance difficulty and cost, and improving maintenance efficiency. In addition, the mutual insulation of the casings of the first and second discharge sockets ensures electrical insulation safety and effectively avoids the problem of the internal discharge socket being burned out due to damage to the external discharge socket, improving the reliability and safety of the battery connector.

Detailed Implementation

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] It should be noted that when a component is referred to as being "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0020] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0021] It's important to understand that in fields like electric vehicles and energy storage devices, batteries are the core energy source, and the power transmission between them and external electrical equipment relies on stable and reliable electrical connectors. Existing battery discharge port structures typically employ integrated or fixed wired discharge port sockets, which are directly screwed onto the battery pack's outer casing 10. When the discharge port socket is worn due to prolonged insertion and removal or damaged by electrical arcing, the entire socket and its connected high-voltage wiring harness need to be disassembled. This process is extremely inconvenient due to limited space, and may damage the connecting wires or introduce new safety hazards.

[0022] Based on this, this application improves upon traditional battery connectors and batteries.

[0023] Please see Figure 1 and Figure 4 The battery connector in this embodiment includes a battery connector 20 that passes through the battery housing 10. The housing 10 is used to install a battery energy storage device, and an electrical connection port 11 is provided on the housing 10. The battery connector 20 includes a first discharge socket 100 and a second discharge socket 200. The second discharge socket 200 is disposed inside the housing 10 and is detachably installed inside the electrical connection port 11. The second discharge socket 200 is electrically connected to the battery energy storage device. The first discharge socket 100 is disposed outside the housing 10 and is detachably installed outside the electrical connection port 11. The first discharge socket 100 is used to electrically connect to the device to be powered. When the first discharge socket 100 and the second discharge socket 200 are installed on the electrical connection port 11, the first discharge socket 100 and the second discharge socket 200 are plugged into and electrically connected through the electrical connection port 11, and the housings of the first discharge socket 100 and the second discharge socket 200 are insulated from each other.

[0024] It should be explained that the outer casing 10 is the external protective structure of the battery, used to house and fix the battery energy storage device. The outer casing 10 has an electrical connection port 11 for mounting a power supply connector; the electrical connection port 11 is a through hole penetrating the wall thickness of the outer casing 10. The second discharge socket 200 is located inside the outer casing 10 and is electrically connected to the battery energy storage device, used to output the electrical energy inside the battery to the outside. The first discharge socket 100 is located outside the outer casing 10 and is used to connect to the plug of external devices to be powered (such as the motor controller of an electric vehicle, the inverter of an energy storage device, etc.) to achieve power transmission. The first discharge socket 100 and the second discharge socket 200 are independently installed on the inner and outer sides of the outer casing 10, respectively, and are electrically connected by plugging in through the electrical connection port 11. That is to say, the first discharge socket 100 and the second discharge socket 200 do not need to be connected by welding or wiring harnesses; electrical conduction can be achieved simply by plugging in. Meanwhile, the housings of the first discharge base 100 and the second discharge base 200 are isolated from each other and do not contact each other in the plugged-in state. The electrical connection between the two is achieved only through their respective internal conductive terminals.

[0025] It is understood that this embodiment achieves modularization of the electrical connection function by splitting the traditional integrated discharge port structure into two independent and separable pluggable parts, one inside and one outside. When the first discharge socket 100 located outside the outer casing 10 is damaged due to electrical arcing or wear caused by frequent plugging and unplugging, the second discharge socket 200 can remain intact because it is located inside the outer casing 10 and the two outer casings 10 are mutually insulated. At the same time, since the first discharge socket 100 and the second discharge socket 200 are electrically connected by a separable pluggable connection, maintenance personnel do not need to operate the high-voltage wiring harness inside the battery casing 10. They only need to remove the damaged first discharge socket 100 from the outside of the battery casing 10 and replace it with a new one. The maintenance process is simple and quick, greatly reducing maintenance difficulty and cost, and improving maintenance efficiency.

[0026] Please refer to the embodiments described in this application. Figure 1 The battery connector 20 in this embodiment also includes a waterproof gasket 300, which is pressed between the first discharge seat 100 and the outer shell 10 to seal the gap between the first discharge seat 100 and the outer shell 10.

[0027] It should be explained that the waterproof gasket 300 is usually a ring-shaped gasket made of rubber or silicone, which is fitted onto the outer circumferential surface of the first discharge base 100. When the first discharge base 100 is locked onto the outer shell 10, the waterproof gasket 300 is compressed between the first discharge base 100 and the outer shell 10, which plays a role in sealing and waterproofing, preventing external moisture or dust from entering the interior of the outer shell 10 through the electrical connection port 11.

[0028] In some embodiments, please refer to Figure 3 In this embodiment, at least one side of the waterproof gasket 300 is provided with a waterproof protrusion 310, which is arranged around the waterproof gasket 300 in the circumferential direction.

[0029] Understandably, the waterproof ring 310 can increase the compression of the waterproof gasket 300, providing greater sealing pressure when the first discharge seat 100 is locked, thereby further improving the sealing and waterproofing effect.

[0030] In some embodiments, please continue reading Figure 3 In this embodiment, the number of waterproof protrusions 310 can be two, and the two waterproof protrusions 310 are arranged concentrically around each other.

[0031] Understandably, the double-layer waterproof ring 310 can form a double sealing barrier. Even if the outer waterproof ring 310 fails partially, the inner waterproof ring 310 can still maintain a reliable sealing effect, significantly improving waterproof reliability.

[0032] In some embodiments of this application, please refer to Figure 4 In this embodiment, the first discharge base 100 has a first protrusion 110 on the side near the outer casing 10 (i.e., the internal connection end), and a first connection terminal 120 for electrical connection with the first discharge base 100 is provided on the first protrusion 110. A blocking platform 130 is provided at least one side of the first protrusion 110 at a distance. At least a portion of the waterproof gasket 300 is engaged between the first protrusion 110 and the blocking platform 130.

[0033] It should be explained that the first protrusion 110 is the plug-in structure of the internal connection end of the first discharge base 100, used to pass through the electrical connection port 11 and plug into the second discharge base 200. The first connection terminal 120 is disposed on the first protrusion 110 and is used to achieve electrical connection with the conductive terminal inside the second discharge base 200. The blocking platform 130 is disposed on the side of the first protrusion 110, forming a certain gap with the first protrusion 110.

[0034] It is understood that the waterproof gasket 300 in this embodiment is positioned and held in the gap between the first protrusion 110 and the blocking platform 130 during installation, ensuring that the waterproof gasket 300 will not shift or fall off during the installation of the first discharge seat 100, thereby improving the convenience of assembly and the reliability of sealing.

[0035] Please refer to the embodiments described in this application. Figure 4 And see Figure 5 In this embodiment, the waterproof gasket 300 is provided with an avoidance notch 320, which is adapted to the blocking platform 130.

[0036] Understandably, the clearance notch 320 allows the waterproof gasket 300 to be smoothly fitted onto the first discharge base 100, while cooperating with the blocking platform 130 to achieve circumferential positioning and prevent the waterproof gasket 300 from rotating or shifting during installation.

[0037] In some embodiments of this application, please refer to Figure 6 and Figure 7 The first protrusion 110 is provided with a foolproof protrusion structure 140, and the second discharge base 200 is provided with a foolproof notch 210, which is adapted to the foolproof protrusion structure 140.

[0038] It should be explained that the anti-mistake protrusion structure 140 and the anti-mistake notch 210 are mutually cooperating physical anti-mistake structures used to ensure that the second discharge base 200 and the first discharge base 100 can only be inserted and mated in the correct direction, preventing the conductive terminals from being misaligned due to incorrect orientation, thereby causing problems such as short circuits or poor contact.

[0039] It is understood that the foolproof protrusion 140 can be configured as a key, ridge, or other shaped protrusion, while the foolproof notch 210 is configured as a groove or notch structure that mates with it. When the first discharge base 100 is inserted in the correct direction, the foolproof protrusion 140 smoothly enters the foolproof notch 210, achieving normal insertion; when the direction is incorrect, the foolproof protrusion 140 interferes with the housing of the second discharge base 200, preventing insertion, thus providing foolproof protection.

[0040] Please refer to the embodiments described in this application. Figure 1 And see Figure 8 , Figure 9 The outer casing 10 is provided with a mounting groove 12, and the electrical connection port 11 is located at the bottom of the mounting groove 12. The mounting groove 12 is used to be installed and adapted to the first discharge base 100.

[0041] It should be explained that the mounting groove 12 is a groove-shaped structure formed by recessing from the outer surface of the outer shell 10 inward. Its shape matches the shape of the first discharge base 100 and is used to accommodate and position the first discharge base 100. The electrical connection port 11 is opened at the bottom of the mounting groove 12 and is a through hole that penetrates the wall thickness of the outer shell 10, allowing the internal connection end (first protrusion 110) of the first discharge base 100 to pass through and be inserted into the first discharge base 100 inside the outer shell 10.

[0042] In some embodiments, please continue reading Figure 1 , Figure 8 and Figure 9 And see Figure 10 The bottom of the mounting groove 12 is provided with a first threaded hole 121, and the second discharge base 200 is provided with a second threaded hole 150. The second threaded hole 150 is provided corresponding to the first threaded hole 121, and can be screwed to the first threaded hole 121 and the second threaded hole 150 to install the second discharge base 200 onto the mounting groove 12.

[0043] Understandably, the first discharge base 100 is inserted into the mounting groove 12 from outside the housing 10, with its internal connecting end (first protrusion 110) passing through the electrical connection port 11. The position of the first discharge base 100 is adjusted so that its second threaded hole 150 is aligned with the first threaded hole 121 at the bottom of the mounting groove 12. Then, a screw is passed through the second threaded hole 150 and tightened into the first threaded hole 121. As the screw is tightened, the first discharge base 100 is pressed into the mounting groove 12, while the waterproof gasket 300 is compressed, achieving reliable mechanical fixation and waterproof sealing.

[0044] In some embodiments of this application, please refer to Figures 11 to 13In this embodiment, the second discharge base 200 is provided with a third threaded hole 220, and the inner wall of the outer shell 10 is provided with a stud 13 (i.e., the mounting post structure corresponding to the third threaded hole 220). The third threaded hole 220 and the stud 13 are correspondingly provided, and the third threaded hole 220 and the stud 13 can be screwed together by screws to install the second discharge base 200 onto the inner wall of the outer shell 10.

[0045] It should be explained that, corresponding to the position of the mounting groove 12, the inner surface of the outer casing 10 is provided with an inwardly protruding mounting post, and the mounting post has a third threaded hole 220 for fixing the second discharge base 200. The second discharge base 200 is provided with a stud 13 corresponding to the position of the third threaded hole 220. By passing a screw through the third threaded hole 220 and locking it in the stud 13, the second discharge base 200 is firmly fixed to the inner side of the outer casing 10.

[0046] Understandably, the second discharge socket 200 and the first discharge socket 100 are respectively fixed to the inner and outer sides of the housing 10 by independent screws, and the two are independent detachable structures. When it is necessary to replace the damaged first discharge socket 100, simply unscrew the screws fixing the first discharge socket 100 to remove it, without disassembling the second discharge socket 200 and its connected high-voltage wiring harness, making the maintenance operation simple and quick.

[0047] Please refer to the embodiments described in this application. Figures 11 to 13 In this embodiment, the second discharge base 200 is also provided with a positioning hole 230, and the inner wall of the outer shell 10 is provided with a positioning post. The positioning hole 230 is inserted and matched with the positioning post to pre-position the second discharge base 200 and the outer shell 10.

[0048] It should be explained that the positioning post and positioning hole 230 are auxiliary installation structures. When installing the second discharge base 200 onto the inner wall of the housing 10, the positioning hole 230 is first aligned with the positioning post and inserted to achieve pre-positioning of the second discharge base 200. After pre-positioning, the third threaded hole 220 of the second discharge base 200 automatically aligns with the third threaded hole 220 on the inner wall of the housing 10, facilitating the subsequent insertion and tightening of screws, and improving assembly efficiency and accuracy.

[0049] Furthermore, to better implement the battery connector 20 in any of the above embodiments, based on the battery connector 20 described above, this application embodiment also provides a battery, which includes a housing 10, a battery energy storage device, and the battery connector 20 as described in any of the above embodiments. The battery energy storage device is disposed inside the housing 10 and is electrically connected to the device to be powered through the battery connector 20 on the housing 10. The housing 10 includes a top cover, and the battery connector 20 is disposed on the top cover.

[0050] It should be explained that a battery energy storage device is a unit inside a battery used to store and release electrical energy, such as a lithium-ion cell or battery module. The housing 10 surrounds and protects the battery energy storage device internally. The top cover is a component of the housing 10, such as the top or side cover of a battery pack. The battery connector 20 is mounted on the top cover, serving as an interface for power transfer between the battery's internal components and external devices.

[0051] In the battery of this embodiment, since the battery connector 20 is used, when the external first discharge socket 100 is damaged due to long-term use, the maintenance personnel only need to remove and replace the first discharge socket 100 from the outside of the top cover, without having to open the outer casing 10 or operate the internal high-voltage wiring harness, which greatly improves the convenience of battery maintenance and maintenance efficiency.

[0052] The assembly process of the battery connector in this embodiment will be described below.

[0053] First, place the second discharge base 200 in the corresponding installation position on the inner surface of the upper cover, and insert the positioning pin into the positioning hole 230 for pre-positioning. Then, use a screw to pass through the third threaded hole 220 of the second discharge base 200 and lock it into the third threaded hole 220 on the inner surface of the upper cover, thereby firmly fixing the second discharge base 200 to the inside of the upper cover. Next, fit the waterproof gasket 300 onto the first discharge base 100. The clearance notch 320 of the waterproof gasket 300 is aligned with the blocking platform 130 on the first discharge base 100 to achieve circumferential positioning of the waterproof gasket 300 and to make the waterproof gasket 300 snap between the first protrusion 110 and the blocking platform 130.

[0054] Next, the first discharge socket 100, equipped with the waterproof gasket 300, is inserted from the outside into the mounting groove 12 of the upper cover, so that its internal connecting end (first protrusion 110) passes through the electrical connection port 11 at the bottom of the mounting groove 12. The position of the first discharge socket 100 is adjusted so that its second threaded hole 150 is aligned with the first threaded hole 121 at the bottom of the mounting groove 12. At the same time, the anti-foolproof protrusion 140 on the first discharge socket 100 is aligned with the anti-foolproof notch 210 on the second discharge socket 200 to ensure the correct insertion direction. Finally, a screw is passed through the second threaded hole 150 of the first discharge socket 100 and tightened into the first threaded hole 121. As the screw is tightened, the first discharge socket 100 is pressed into the mounting groove 12, and the waterproof gasket 300 is compressed between the first discharge socket 100 and the bottom surface of the mounting groove 12, achieving a reliable waterproof seal.

[0055] Simultaneously, the internal connecting end of the first discharge base 100 is fully inserted into the second discharge base 200, and the first connecting terminal 120 achieves a reliable electrical connection with the conductive terminals inside the second discharge base 200. In this structure, the housing of the second discharge base 200 and the housing of the first discharge base 100 are isolated from each other and do not contact each other in the plugged-in state. The electrical connection is achieved only through the conductive terminals inside both. This design ensures that even if the external first discharge base 100 is burned due to electric arcing, the damage is usually limited to the first discharge base 100 itself and its internal terminals, while the second discharge base 200, which is plugged into it and located inside the housing 10, remains intact because it does not directly bear the insertion and extraction stress and arc impact.

[0056] In some embodiments, the housing 10 is formed using a metal die-casting process, resulting in high structural strength and good heat dissipation performance. The top cover is part of the housing 10, and the mounting groove 12 on its outer surface is formed by die casting or machining.

[0057] In some embodiments, the second discharge base 200 includes an insulating base and conductive terminals encapsulated within the base. One end of the base is provided with an interface for insertion into the first discharge base 100, and the other end is used to connect to the high-voltage wiring harness of the battery energy storage device.

[0058] In some embodiments, the first discharge base 100 has an internally encapsulated conductive terminal and an externally insulating shell, the shape of which is designed to fit the mounting groove 12 to ensure stability and aesthetics after installation.

[0059] In some embodiments, the waterproof gasket 300 is made of rubber or silicone, has good elasticity and weather resistance, and can maintain reliable sealing performance over a wide temperature range.

[0060] In the battery connector of this application, the battery can be a battery for electric bicycles, a battery for electric motorcycles, or a battery for energy storage devices. The device to be powered can be a motor controller for an electric bicycle, a drive system for an electric motorcycle, or an inverter for an energy storage device, etc.

[0061] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.
