Description

Technical Field

[0001] This invention relates to the field of battery technology, and particularly to an electrode assembly, a battery cover, and a battery. Background Technology

[0002] Energy storage batteries not only play a crucial role in ensuring a stable energy supply and improving energy efficiency, but also drive the vigorous development of the new energy industry, profoundly impacting our lives and future. Existing energy storage batteries generally have terminal assemblies on the outside of the casing. These assemblies consist of a positive terminal and a negative terminal, used for external power transmission or charging. When charging and discharging using conductive wires with terminals, existing terminal assemblies typically have threaded holes at the top, and the top surface of the terminal is horizontal (0° slope), secured with bolts. Existing terminal assemblies generally have the following drawbacks: they only have one positive and one negative terminal. When the energy storage battery transmits power externally using conductive wires, if there are multiple electrical devices, multiple conductive wire terminals need to be connected to the same positive and negative terminal. This overlapping contact of multiple conductive wire terminals may lead to increased resistance and uneven current distribution. Summary of the Invention

[0026] refer to Figures 1 to 6This embodiment discloses a terminal assembly, including a terminal base 400, a conductive block 410, a fixing member, and at least two terminals 420. The conductive block 410 is electrically connected to the terminal base 400. The terminal 420 is fixedly mounted on the conductive block 410 and electrically connected to the conductive block 410. The fixing member is connected to the terminal 420 and used to fix the terminals to the conductive block 410. A conventional approach involves a threaded hole in the upper part of the terminal 420, with the top surface of the terminal 420 designed horizontally (slope angle of 0°). When multiple devices need power, the terminals 510 on multiple conductive wires 500 are stacked, aligned with the threaded hole, and fixed with bolts. However, the stacked terminals 510 on multiple conductive wires 500 can sag due to their own weight and external loads. Under vibration conditions, the terminals 510 and the terminal 420 can easily loosen. In this embodiment, at least two pole posts 420 are provided. The terminals 510 on different conductive wires 500 can be connected to different pole posts 420 respectively. One terminal 510 corresponds to one pole post 420. The outer peripheral wall of the pole post 420 is provided with threads, and the fastener is a nut. Then, the nut is used to lock it, which avoids the problem of increased contact resistance and uneven current distribution caused by multiple terminals stacked on a single pole post.

[0027] In one embodiment, the conductive block 410 is L-shaped and includes two fixedly connected conductive bars. The connection point of the two conductive bars is electrically connected to the electrode base 400. There are two electrodes 420, each disposed on one of the two conductive bars. The L-shaped conductive block 410 and the two electrodes 420, with a certain distance between them, allow terminals 510 on different conductive wires 500 to be connected to different electrodes 420, reducing the risk of different terminals 510 touching each other and reducing the risk of conductive wires 500 crossing, tangling, or colliding with other components.

[0028] In one embodiment, the system further includes a locking conductive post 430, which has a locking hole 431; the connection of the conductive busbar has a rotating through hole 411; the pole base 400 has a conductive shoulder surface 403, the upper part of the conductive shoulder surface 403 is the locking post 401; the conductive block 410 is sleeved in the locking post 401 through the rotating through hole 411; the lower end face of the conductive block 410 abuts against the conductive shoulder surface 403; and the locking conductive post 430 is detachably connected to the locking post 401 through the locking hole 431. The conductive block 410 can rotate around the locking post 401. The locking conductive post 430 locks or releases the conductive block 410. The lower end face of the conductive block 410 abuts against the conductive shoulder surface 403. When the locking conductive post 430 locks the conductive block 410, the lower end face of the conductive block 410 and the conductive shoulder surface 403 are in surface contact, which increases the effective conductive area between the conductive block 410 and the terminal base 400. The conductive block 410 can rotate around the locking post 401, causing the terminal 420 to point in different directions. The conductive wire 500 can flexibly adjust its outlet direction according to the equipment layout. When the battery's installation position inside the equipment is limited, the conductive block 410 can be rotated to make the terminal 420 face the maintenance port or wiring trough. During maintenance, the terminal 420 can be rotated to an open position to facilitate the installation and removal of the terminal 510 without disassembling surrounding components. When the locking conductive post 430 locks the conductive block 410, the locking conductive post 430 is electrically connected to the electrode base 400. The locking conductive post 430 can also output power or be used to charge the battery. Either the locking conductive post 430 or the electrode 420 can be selected for outputting power as needed. The locking conductive post 430 can be frustum-shaped with anti-slip texture. Other conductive wires are connected to clips and held onto the locking conductive post 430 by the clips.

[0029] In one embodiment, the lower part of the conductive block 410 is provided with a downward-facing annular insertion edge 415 surrounding the rotating through hole 411. The annular insertion edge 415 is conical in shape, wider at the top and narrower at the bottom. The conductive shoulder surface 403 is provided with an annular groove 406 with an opening in a conical shape, wider at the top and narrower at the bottom. The lower end face of the conductive block 410 is also circumferentially distributed with elastic conductive fingers 416. The conductive shoulder surface 403 is also provided with a conductive annular groove 407. The elastic conductive fingers 416 and the conductive annular groove 407 are respectively located around the annular insertion edge 415. The elastic conductive finger 416, located around the annular groove 406, includes a root, an S-shaped elastic arm, and an arc-shaped contact at the end. The conductive block 410 is fitted onto the locking post 401 through a rotating through-hole 411. When the locking conductive post 430 is locked, the annular insertion edge 415 inserts into the annular groove 406 to form a first conductive path. The arc-shaped contact of the elastic conductive finger 416 elastically abuts against the conductive annular groove 407 to form a second conductive path. A gap is maintained between the lower end face of the conductive block 410 and the upper end face of the conductive shoulder surface 403. The conductive annular groove 407 is located around the annular groove 406 and is concentrically arranged with the annular groove 406. The conductive annular groove 407 is an annular groove structure with a circular arc cross-section, used to accommodate the arc-shaped contact of the elastic conductive finger 416 and define its contact position. The depth of the conductive annular groove 407 is less than the protrusion height of the elastic conductive finger 416 in its free state, ensuring appropriate elastic compression during locking. The width of the conductive ring groove 407 is slightly larger than the width of the arc-shaped contact, allowing for a certain radial tolerance. However, the groove width should not be too large to prevent the arc-shaped contact from sliding within the groove and causing poor contact. An inlet angle can be provided at the lower end of the annular insertion edge 415 to facilitate quick alignment with the annular groove 406 during insertion. Elastic conductive fingers 416 are circumferentially distributed on the lower end face of the conductive block 410, located around the annular insertion edge 415. The number of elastic conductive fingers 416 is 4 to 12, preferably 6 to 8, arranged at equal intervals along the circumference. Each elastic conductive finger 416 includes a root, an S-shaped elastic arm, and an arc-shaped contact at the end. The S-shaped structure has a larger elastic stroke than a straight or L-shaped arm, providing more sustained contact pressure under the same preload. The arc-shaped contact matches the bottom of the conductive ring groove 407. The small contact area and concentrated contact pressure of the arc-shaped contact facilitate piercing the surface oxide film to form direct metal-to-metal contact. The installation of the conductive block 410 includes the following steps: 1. The conductive block 410 is fitted onto the locking post 401 of the pole base 400 through the rotating through hole 411. At this time, the conductive block 410 can rotate freely around the locking post 401, the annular insertion edge 415 is inserted into the annular groove 406, and the elastic conductive finger 416 abuts against the conductive ring groove 407; 2. According to the internal spatial layout of the equipment and the direction of the wires, rotate the conductive block 410 to the target position; 3. Align the locking hole 431 of the locking conductive post 430 with the locking post 401, screw it in and tighten it.As the locking conductive post 430 moves downward, its lower end face first contacts the upper end face of the conductive block 410. The conductive block 410 moves downward, and the annular insertion edge 415 gradually inserts into the annular groove 406. Since the annular groove 406 is wider at the top and narrower at the bottom, the outer conical surface of the annular insertion edge 415 contacts the inner conical surface of the groove wall. Simultaneously, the arc-shaped contact of the elastic conductive finger 416 contacts the bottom of the conductive ring groove 407, and the S-shaped elastic arm begins to compress and deform. Tightening continues until the specified torque is reached, the annular insertion edge 415 is fully inserted, the elastic conductive finger 416 reaches the designed compression amount, and the conductive block 410 stops moving downward. The following describes the working principle of dual-path conductivity: Current mainly flows from the pole base 400 through the conductive shoulder surface 403, the annular groove 406, and the annular insertion edge 415 to the conductive block 410, forming the first conductive path; a portion of the current flows through the conductive ring groove 407 and the elastic conductive finger 416 to the conductive block 410, forming the second conductive path. Compared to the scheme where the lower end face of the conductive block 410 and the conductive shoulder surface 403 are in direct surface contact, the surface contact scheme has the following drawbacks: only micro-protrusions are in actual contact; the current is concentrated in the micro-protrusions, resulting in extremely high current density and localized heating; vibration / thermal cycling leads to fatigue, oxidation, and cold solder joint fracture of the micro-protrusions; once the planes separate, the circuit is broken, with no fault tolerance. The scheme in this embodiment uses a dual-path conduction, which has the following advantages: a conical interference fit forms the first main conduction path; the elastic conductive finger 416 makes multi-point contact with the conductive ring groove 407, forming a redundant backup second path. Under vibration, because the elastic conductive finger 416 has an S-shaped elastic arm, it can continue to maintain the electrical connection between the conductive block 410 and the conductive shoulder surface 403.

[0030] In one embodiment, the upper end face 413 of the conductive block 410 is horizontally arranged, and the upper end face 413 of the conductive block 410 is provided with a slope 412. The slope 412 has an inclined surface 414, and the electrode post 420 is vertically fixed on the inclined surface 414. The electrode post 420 is electrically connected to the conductive block 410 through the slope 412. The inclined surface 414 and the upper end face 413 of the conductive block 410 form an acute angle. The upper end face 413 of the conductive block 410 is generally horizontally arranged, and the slope 412 is provided on the upper end face 413 of the conductive block 410, and the electrode post 420 is vertically fixed on the inclined surface 414. In a conventional approach, multiple terminals 510 of multiple conductive wires 500 are stacked and installed on the top surface of the pole post 420. When the conductive wires 500 droop, under vibration conditions, the terminals 510 are prone to loosening, leading to poor contact. A ramp 412 is provided on the upper end surface 413 of the conductive block 410, and the pole post 420 is vertically fixed on the ramp 414. In this embodiment, the pole post 420 is cylindrical, and the central axis of the pole post 420 forms an acute angle with the horizontal plane. After the terminals 510 on the conductive wires 500 are sleeved on the outer peripheral wall of the pole post 420, the nut presses the terminals 510 onto the conductive block 410, and the terminals 510 are also supported on the conductive block 410. When the conductive wires 500 droop, under vibration conditions, the inner hole of the terminal 510 and the outer peripheral surface of the pole post 420 still maintain contact, reducing the possibility of the terminals 510 and the pole post 420 loosening and causing poor contact.

[0031] In one embodiment, the cross-section of the pole post 420 is stepped, with a smaller top and a larger bottom, and includes at least two sections of different diameters. The fixing member includes multiple nuts with different inner diameters, and the poles are provided with external threads, with the nuts engaging with the threads of the poles. The fixing member includes nuts of M10, M8, and M6, and the terminal 510 also has M10, M8, and M6 specifications, where M10, M8, and M6 refer to diameters of 10 mm, 8 mm, and 6 mm, respectively. The cross-section of the pole post 420 is stepped, with a smaller top and a larger bottom. It can be configured with three sections of different diameters: a first pole post 421, a second pole post 422, and a third pole post 423. These three poles are coaxially aligned. The diameters of the first pole post 421, the second pole post 422, and the third pole post 423 are respectively used to accommodate M10, M8, and M6 terminals 510. For example, the M10 terminal 510 can be fitted onto the first pole post 421. The nut presses the M10 terminal 510 onto the conductive block 410; the M8 terminal 510 can be sleeved on the second post 422, and the M8 terminal 510 can be pressed onto the upper surface of the first post 421 using the M8 nut; the M6 ​​terminal 510 can be sleeved on the third post 423, and the M6 ​​terminal 510 can be pressed onto the upper surface of the second post 422 using the M6 ​​nut. This eliminates the need to replace the pole or add an adapter, thus eliminating intermediate parts such as adapters and adapter sleeves and reducing costs.

[0032] This embodiment also provides a battery cover, including a cover body 100, and a terminal post assembly as described above. The terminal post assembly has two sets. The cover body 100 has two terminal post mounting holes 140, and the two sets of terminal post assemblies are respectively disposed within the two terminal post mounting holes 140. It also includes a sealing ring 440. The upper and lower parts of the terminal post base 400 are respectively provided with an upper abutment shoulder 405 and a lower abutment shoulder 402. The sealing ring 440 is sleeved on the terminal post base 400, and the sealing ring 440 is located between the upper abutment shoulder 405 and the lower abutment shoulder 402. Between the terminals, an upper shoulder 142 and a lower shoulder 141 are respectively provided from top to bottom within the terminal mounting hole 140. The upper and lower end faces of the sealing ring 440 abut against the lower end face of the upper abutment shoulder 405 and the upper end face of the upper shoulder 142, respectively. The lower end face of the lower abutment shoulder 402 abuts against the upper end face of the lower shoulder 141. An anti-rotation protrusion 143 is also provided on the inner wall between the upper shoulder 142 and the lower shoulder 141, and an anti-rotation opening 404 is provided on the outer side wall of the lower abutment shoulder 402. The anti-rotation protrusion 143 is engaged with the anti-rotation opening 404. A battery generally has two sets of terminals, a positive terminal and a negative terminal. In this embodiment, there are two sets of terminal assembly, which serve as the positive and negative terminals of the battery, respectively. The cover 100 is provided with two terminal mounting holes 140, and the two sets of terminal assembly are respectively located in the two terminal mounting holes 140. The center of the cover 100 is the inner side, and the edge of the cover 100 is the outer side. The upper end face 413 of the conductive block 410 is provided with a slope 412. The slope 412 has an inclined surface 414. The height of the slope 412 gradually decreases from the inner side to the outer side. The inclined surface 414 forms an angle with the upper end face 413 of the conductive block 410. The angle is an acute angle, preferably 5° to 20°. If the angle is less than 5°, the slope is too gentle and cannot effectively compensate for the sag of the conductive wire 500. If the angle is greater than 20°, the pole post 420 will have a noticeable tilt. The angle is further preferably 10°. The nut fixes the terminal 510 to the pole post 420. The locking force of the nut and the component of gravity work together to maintain the fit. The conductive wire 500 and the terminal 510 are generally electrically connected by welding. The pole mounting hole 140 is located at the edge of the cover 100. The pole assembly is located at the edge of the cover 100. The pole 420 is cylindrical, and the central axis of the pole 420 forms an acute angle with the horizontal plane. After the terminal 510 on the conductive wire 500 is sleeved on the outer peripheral wall of the pole 420, when the conductive wire 500 hangs down, under vibration conditions, the inner hole of the terminal 510 and the outer peripheral surface of the pole 420 still maintain contact, reducing the possibility of poor contact caused by the loosening of the terminal 510 and the pole 420. The conductive wire 500 is supported by the edge of the cover 100, reducing the bending vibration force between the conductive wire 500 and the terminal 510, and extending the service life of the conductive wire 500.First, the sealing ring 440 is fitted onto the cylinder of the terminal base 400. The terminal base 400 is then installed inside the terminal mounting hole 140. The lower end face of the sealing ring 440 abuts against the upper end face of the upper shoulder 142, and the lower end face of the lower abutting shoulder 402 abuts against the upper end face of the lower shoulder 141, thus preventing the terminal base 400 from moving downwards. Multiple anti-rotation protrusions 143 are also provided on the inner wall between the upper shoulder 142 and the lower shoulder 141, and multiple anti-rotation slots 404 are provided on the outer wall of the lower abutting shoulder 402. The anti-rotation protrusions 143 engage with the anti-rotation slots 404, constraining the terminal base 400 from rotating and also providing a certain degree of friction, increasing the frictional force between the terminal base 400 and the terminal mounting hole 140. The sealing ring 440 can prevent external moisture and dust from entering the battery, preventing short circuits or corrosion of the cell.

[0033] In one embodiment, a raised ring 144 is provided around the upper end face of the pole mounting hole 140. The raised ring 144 protrudes from the upper end face of the cover 100, and the upper end face of the sealing ring 440 is flush with the upper end face of the raised ring 144. The raised ring 144 protrudes from the upper end face of the cover 100, and the upper end face of the sealing ring 440 is flush with the upper end face of the raised ring 144, forming a physical barrier to prevent external liquid from flowing directly to the sealing interface along the end face. It also provides visual inspection convenience, and after assembly, the height of the raised ring 440 can be used to visually determine whether the sealing ring 440 is installed in place.

[0034] In one embodiment, both sides of the cover 100 are provided with rope grooves 110, and hooks 111 are provided at the openings of the rope grooves 110. A gap 112 for a carrying rope is formed between the hooks 111 and the rope grooves 110. The hooks 111 are composed of a rear cantilever arm 114 and a front cantilever arm 113. The front cantilever arm 113 and the rear cantilever arm 114 are respectively located on the front and rear sides of the rope grooves 110. The rear cantilever arm 114 and the front cantilever arm 113 are arranged facing each other. Both the rear cantilever arm 114 and the front cantilever arm 113 are provided with guide rails. The cover 100 has two guide slopes 115 forming a gap 112. Both sides of the cover 100 also have handle areas, which are divided into a deep-set handle 120 and two shallow-set handles 130. The deep-set handle 120 has a greater recessed depth than the shallow-set handles 130. A cord groove 110 is located on the deep-set handle 120, and its upper and lower ends respectively penetrate and connect the upper surface of the cover 100 and the upper surface of the deep-set handle 120. The two shallow-set handles 130 are located on the front and rear sides of the deep-set handle 120. Energy storage batteries are relatively heavy, making handle design essential. However, existing solutions each have drawbacks: external carrying straps, while supporting one-handed carrying or shoulder carrying, are inconvenient in narrow installation environments such as those for car batteries; while recessed handle grooves are simple, they force two-handed operation, significantly reducing convenience. The carrying cable 200 has snap-fit ​​buckles 210 connected to both ends. The cover 100 has a cable tray 110. Users can pass the carrying cable 200 through the gap 112 into the cable tray 110 to retrieve and transport the battery. During use, the snap-fit ​​buckles 210 are engaged with the lower end face of the cable tray 110. Users can also remove the carrying cable 200 from the cable tray 110 and retrieve the battery through the handle area. This simple and convenient operation solves the problem of inconvenient handles in existing battery storage systems. The snap-fit ​​buckle 210 is rectangular in shape, with a larger lateral area than the cable tray 110. During use, the upper end face of the snap-fit ​​buckle 210 abuts against the lower end face of the cable tray 110. When the carrying cable 200 is not needed, it can be pulled out from the gap 112. The left and right sides of the cover 100 are recessed inward to form a handle area, allowing the user to reach into the handle area to retrieve the battery. The rear cantilever arm 114 and the front cantilever arm 113 are arranged facing each other, with the gap 112 located at the facing point of the rear cantilever arm 114 and the front cantilever arm 113. The rear cantilever arm 114 and the front cantilever arm 113 form a hook, preventing the carrying cable 200 from easily detaching directly from the rope groove 110. Two guide ramps 115 form the gap 112, allowing the carrying cable 200 to enter or exit the rope groove 110 along the guide ramps 115 during installation. The diameter of the carrying cable 200 can be slightly larger than the gap 112, allowing for some compression deformation, which can be used to compress the carrying cable 200 into the gap 112 during installation.In its normal state, the carrying cable 200 is located within the cable groove 110. Since the diameter of the carrying cable 200 is slightly larger than the gap 112, it is not easily detached from the gap 112. The left and right sides of the cover 100 are recessed inwards to form two deeply recessed handles 120, allowing the user's left and right hands to reach into these handles to extract the battery. The left and right sides of the cover 100 are also recessed inwards to form four shallowly recessed handles 130. When the battery is heavy and requires multiple people to lift and move it, these handles can be used for operation. The battery's internal structure is relatively compact, and some cell supports or BMS boards may extend upwards into the cover 100. The recessed depth of the deep handles 120 is greater than the recessed depth of the shallow handles 130 to minimize the area of ​​the handle area formed by the inward recesses of the cover 100, preventing the recessed handle area from obstructing the internal structure of the battery. Furthermore, when using the conductive wire 500, the conductive block 410 can be rotated as needed to adjust the pole 420 to a suitable position. The conductive wire 500 is then secured in the gap 112 or inserted into the cord groove 110. The gap 112 or cord groove 110 serves as a fixing point for the conductive wire 500. Existing gaps 112 or cord grooves 110 can be reused as the fixing structure for the conductive wire 500, eliminating the need for additional clips. The pole 420 is located diagonally above the gap 112 or cord groove 110, providing conductivity. The upper end face 413 of the block 410 is provided with a slope 412. The terminal 510 of the conductive wire 500 abuts against the slope 412 of the conductive block 410. The conductive wire 500 extends along the gap 112 or the cord groove 110 and is then constrained by the gap 112 or the cord groove 110. When the conductive wire 500 hangs down, under vibration conditions, the vibration between the terminal 510 and the pole post 420 is reduced, further reducing the possibility of the terminal 510 and the pole post 420 becoming loose and causing poor contact.

[0035] This embodiment also provides a battery, including a battery cover as described above, and a bottom shell 300, wherein the battery cover is disposed on the bottom shell 300. Battery cells, BMS boards, and other structures can be installed inside the bottom shell 300, and the cover 100 is disposed on the bottom shell 300.

[0036] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
