Description

Technical Field

[0001] This invention relates to the field of battery technology, specifically to a battery charging and discharging device. Background Technology

[0002] Battery charging and discharging equipment is a professional device used to charge and discharge various types of batteries. It is widely used in battery research and development, production, quality testing and maintenance. Battery charging and discharging equipment features multifunctionality, high-precision control, high degree of automation, good safety and data analysis capabilities.

[0003] Publication No. CN219611370U discloses a battery charging and discharging device, which includes: a housing, a charging and discharging assembly, and a cover. The housing has an accommodating space, the charging and discharging assembly is disposed within the accommodating space, and the cover is movably connected to the housing. The battery charging and discharging device further includes a sealing ring and a pressure relief assembly. The sealing ring is disposed on the side of the housing facing the cover. When the housing and the cover are in an engaged state, the sealing ring contacts the housing and the cover respectively. The pressure relief assembly is disposed on the housing and / or the cover.

[0004] While the aforementioned applications and prior art can improve overall lifespan and stability, making them adaptable to complex and ever-changing outdoor environments, they require additional charging cables when charging excessively large batteries. These charging cables can be tripping hazards, and during the winding process, external particles adhere to the cable's surface. This friction between the particles and the cable's sheath after winding causes scratches, affecting subsequent use. Furthermore, when cleaning the surface, particles accumulate inside the brush bristles, leading to repeated particle buildup upon subsequent brush cleaning. Therefore, we propose a battery charging and discharging device. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a battery charging and discharging device that has advantages such as preventing tripping and breakage, preventing scratches, and preventing accumulation. It solves the problems of the aforementioned applications and existing technologies, which require the use of an additional charging cable when charging excessively large batteries. This charging cable can easily cause tripping hazards, and during the winding process, external particles adhere to the surface of the charging cable. This leads to friction between the particles and the cable's outer sheath after winding, causing scratches and affecting subsequent use. Furthermore, when cleaning the surface of the charging cable, particles accumulate inside the bristles, leading to repeated particle accumulation on the surface when the bristles clean the cable again.

[0016] Furthermore, the cleaning assembly includes a T-shaped toothed plate fixedly connected inside the drive box and a rotating tooth rotatably connected to the surface of the restraint block. The rotating tooth meshes with the T-shaped toothed plate for transmission. Several bristles are fixedly connected inside the rotating tooth. The bottom of the drive box has a slot for the rotating tooth to move.

[0017] Furthermore, the anti-stacking assembly includes a T-shaped strip fixedly connected to the surface of the transmission bar and an air supply cylinder fixedly connected to the inside of the drive box.

[0018] Furthermore, the anti-stacking assembly also includes a fixed cylinder fixedly connected inside the drive box. The fixed cylinder is fixedly connected to the gas supply pipe.

The top of the extension cylinder is fixedly connected to the bottom of the first spring. A movable inclined plate is fixedly connected to the bottom of the extension cylinder.

[0019] Furthermore, the anti-stacking assembly also includes several telescopic rods fixedly connected to the top of the T-shaped block. Each of the telescopic rods has a second spring inside. A fixing plate is fixedly connected to the top of the telescopic rods. A fixing inclined plate is fixedly connected to one side of the fixing plate.

A charging interface is provided on one side of the discharge box.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the present invention provides a battery charging and discharging device, which has the following beneficial effects:

[0025] 1. This battery charging and discharging equipment, through the cooperation of the cable roller and the winding assembly, starts the drive motor, which drives the rotating plate to rotate via the drive rod. The rotating plate then drives the binding block to rotate via the drive box. During the rotation of the binding block, the binding block drives the discharge wire to be wound onto the surface of the cable roller through the opening. This prevents excess discharge wire from accumulating on the ground and becoming entangled, thus preventing the operator from tripping and causing the discharge wire to disconnect from the battery that needs charging. This achieves the effect of preventing tripping and disconnection.

[0026] 2. This battery charging and discharging equipment, through the coordinated use of the cable assembly and the cleaning assembly, works as follows: During the rotation of the drive box, the cable roller drives the drive gear to rotate via teeth. The drive gear, through the transmission assembly, drives the rotating rod to rotate, which in turn drives the limit rod to rotate via the drive disc. This causes the limit rod to drive the transmission bar to slide inside the limit block. The transmission bar, through the T-shaped block, drives the restraining block to move, which in turn drives the rotating teeth to move. During the movement of the rotating teeth, the T-shaped tooth plate meshes with the rotating teeth, causing them to rotate. This causes the brush bristles to rotate, thus sweeping away particles from the surface of the discharge wire during rotation. This prevents particles from being squeezed against the wire's outer sheath after winding, which could cause scratches on the wire's outer sheath and affect subsequent use, thereby achieving the effect of preventing scratches.

[0027] 3. This battery charging and discharging equipment, through the combined use of the cable assembly and the anti-stacking assembly, utilizes the following: During the sliding of the transmission bar, the transmission bar drives the sealing disc to slide inside the gas cylinder via the T-shaped bar. This allows the gas inside the gas cylinder to enter the fixed cylinder through the gas pipe, which in turn causes the extension cylinder to move out and stretches the first spring, bringing the moving inclined plate and the fixed inclined plate to the same horizontal height. As the T-shaped block moves the fixed plate and the fixed inclined plate via the telescopic rod, the moving inclined plate presses against the fixed inclined plate, compressing the telescopic rod. When the moving inclined plate and the fixed plate are no longer in contact, the telescopic rod quickly returns to its original state. The vibration generated by the retraction of the telescopic rod is then transmitted to the rotating teeth through the T-shaped block and the restraining block, causing particles between the bristles to be discharged from the interior of the rotating teeth through the through groove. This prevents particles from continuously accumulating and affecting subsequent normal use, thus achieving the effect of preventing accumulation.

[0028] 4. This battery charging and discharging equipment, through the cooperation of the cable assembly and the cable roller, during the rotation of the drive box, the cable roller drives the drive gear to rotate through the teeth, the drive gear drives the rotating rod to rotate through the transmission assembly, and the rotating rod drives the limit rod to rotate through the drive disc, which in turn drives the transmission bar to slide inside the limit block. The transmission bar drives the binding block to move back and forth through the T-block, and the binding block drives the discharge wire to move back and forth through the opening, so that the discharge wire can be smoothly wound onto the surface of the cable roller, thereby achieving a stable winding effect.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The devices or elements referred to in the embodiments of this application or implied herein must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the embodiments of this application. In the description of the embodiments of this application, "a plurality of" means two or more, unless otherwise precisely specified.

[0046] For a specific implementation example, please refer to Implementation Example 1. Figures 1 to 7 A battery charging and discharging device includes: a discharge box 1 and a cable roller 14 fixedly connected to the back of the discharge box 1.

[0047] A discharge wire 141 is disposed on the surface of the cable roller 14. A control panel 11 is disposed on the surface of the discharge box 1. A power-off switch 12 is disposed on the surface of the discharge box 1. An audible and visual alarm 13 is fixedly connected to the top of the discharge box 1. Several energy storage blocks are disposed inside the discharge box 1. The energy storage blocks are connected to each other by connecting wires. One end of the discharge wire 141 is connected to the energy storage block. A connector is disposed at the end of the discharge wire 141 away from the energy storage block. A charging interface is disposed on one side of the discharge box 1.

[0048] The winding assembly 2 is disposed inside the cable roller 14 and is used to wind the discharge wire 141 onto the surface of the cable roller 14. The winding assembly 2 includes a drive motor 21 fixedly connected to the back of the discharge box 1. A drive rod 211 is fixedly connected to the output end of the drive motor 21. A rotating plate 212 is fixedly connected to the surface of the drive rod 211. A drive box 22 is fixedly connected to the top of the rotating plate 212. A moving groove 221 is provided at the bottom of the drive box 22. A restraining block 23 is slidably connected inside the moving groove 221. An opening 231 is provided on the surface of the restraining block 23. The discharge wire 141 is disposed inside the opening 231.

[0049] The cable assembly 3 is located inside the drive box 22 and is used to arrange the discharge wires 141 in an orderly manner on the surface of the cable roller 14.

[0050] Cleaning component 4 is located inside drive box 22 and is used to clean impurities on the surface of discharge wire 141;

[0051] Anti-stacking component 5 is installed inside the drive box 22 to prevent impurities from accumulating inside the cleaning component 4;

[0052] It should be noted that the control panel 11 is electrically connected to the audible and visual alarm 13 and the drive motor 21. The power-off switch 12 can prevent the discharge line 141 from being de-energized when the energy storage block inside the discharge box 1 fails. The audible and visual alarm 13 can remind the operator to de-energize when the energy storage block inside the discharge box 1 fails. One end of the drive box 22 is rotatably connected to the back of the discharge box 1. Several ball bearings are installed inside the opening 231. The ball bearings can prevent the opening 231 from scratching the surface of the discharge line 141.

[0053] When it is necessary to wind the excess discharge wire 141 onto the surface of the cable roller 14, the drive motor 21 is started. The drive motor 21 drives the rotating plate 212 to rotate through the drive rod 211. The rotating plate 212 drives the binding block 23 to rotate through the drive box 22. During the rotation of the binding block 23, the binding block 23 drives the discharge wire 141 to wind onto the surface of the cable roller 14 through the opening 231, so that the excess discharge wire 141 will not accumulate on the ground and become tangled, which would cause the operator to trip and cause the discharge wire 141 to disconnect from the battery that needs to be charged.

[0054] For a specific embodiment two, please refer to Figures 1 to 8 Based on the battery charging and discharging device provided in Specific Embodiment 1, this embodiment provides a further technical solution:

[0055] The cable assembly 3 includes several teeth 31 fixedly connected to the surface of the cable roller 14, a drive gear 32 rotatably connected to the inside of the drive box 22, and a rotating rod 34 rotatably connected to the inside of the drive box 22. The drive gear 32 meshes with the several teeth 31 for transmission, and the rotating rod 34 and the drive gear 32 are transmitted through a transmission assembly 33. The cable assembly 3 also includes a limiting block 35 fixedly connected to the inside of the drive box 22. A drive disk 341 is fixedly connected to the surface of the rotating rod 34, a limiting rod 342 is fixedly connected to the surface of the drive disk 341, a transmission bar 343 is rotatably connected to the surface of the limiting rod 342, a T-shaped block 344 is fixedly connected to the surface of the transmission bar 343, the bottom of the T-shaped block 344 is fixedly connected to the top of the restraint block 23, and the transmission bar 343 is slidably connected inside the limiting block 35.

[0056] It should be noted that the transmission assembly 33 includes a rotating rod rotatably connected inside the drive box 22 and a driven bevel gear fixedly connected to the surface of the rotating rod 34. The driven gear and the driving bevel gear are fixedly connected to the surface of the rotating rod. The driven gear meshes with the driving gear 32 for transmission, and the driving bevel gear meshes with the driven bevel gear for transmission. The transmission bar 343 includes a main rotating bar rotatably connected to the surface of the limiting rod 342. A secondary rotating bar is rotatably connected to the surface of the main rotating bar. The secondary rotating bar is slidably connected inside the limiting block 35.

[0057] When the discharge wire 141 needs to be wound in an orderly manner on the surface of the cable roller 14, during the rotation of the drive box 22, the cable roller 14 drives the drive gear 32 to rotate through the teeth 31. The drive gear 32 drives the rotating rod 34 to rotate through the transmission assembly 33. The rotating rod 34 drives the limiting rod 342 to rotate through the drive disc 341. In turn, the limiting rod 342 drives the transmission bar 343 to slide inside the limiting block 35. The transmission bar 343 drives the binding block 23 to move through the T-block 344. The binding block 23 drives the discharge wire 141 to be wound in an orderly manner on the surface of the cable roller 14 through the opening 231, thereby preventing the discharge wire 141 from always accumulating on a certain surface of the cable roller 14.

[0058] For a specific embodiment three, please refer to Figures 1 to 10 Based on the battery charging and discharging device provided in Specific Embodiment Two, this embodiment provides a further technical solution:

[0059] The cleaning component 4 includes a T-shaped toothed plate 41 fixedly connected inside the drive box 22 and a rotating tooth 42 rotatably connected to the surface of the restraint block 23. The rotating tooth 42 meshes with the T-shaped toothed plate 41 for transmission. Several bristles 421 are fixedly connected inside the rotating tooth 42. The bottom of the drive box 22 is provided with a slot 222 for the rotating tooth 42 to move.

[0060] When it is necessary to clean the particles on the surface of the discharge wire 141, when the transmission bar 343 drives the binding block 23 to move through the T-shaped block 344, the binding block 23 drives the rotating tooth 42 to move. During the movement of the rotating tooth 42, the T-shaped tooth plate 41 drives the rotating tooth 42 to rotate through meshing, which in turn drives the brush bristles 421 to rotate. This allows the brush bristles 421 to sweep away the particles on the surface of the discharge wire 141 during rotation, thereby preventing the particles from being squeezed against the surface of the discharge wire 141 after it is wound up, which would cause scratches on the surface of the discharge wire 141 and affect its subsequent use.

[0061] For a specific implementation example, please refer to Implementation Example 4. Figures 1 to 13 Based on the battery charging and discharging device provided in Specific Embodiment Three, this embodiment provides a further technical solution:

[0062] The anti-stacking assembly 5 includes a T-shaped bar 51 fixedly connected to the surface of the transmission bar 343 and an air supply cylinder 52 fixedly connected to the inside of the drive box 22. A sealing disc 511 is fixedly connected to one side of the T-shaped bar 51, and the sealing disc 511 is located inside the air supply cylinder 52. An air supply pipe 521 is fixedly connected to the top of the air supply cylinder 52. The anti-stacking assembly 5 also includes a fixed cylinder 53 fixedly connected to the inside of the drive box 22. The fixed cylinder 53 is fixedly connected to the air supply pipe 521. A one-way valve 531 is provided at the top of the fixed cylinder 53. A first spring 532 is fixedly connected inside the fixed cylinder 53. An extension cylinder 533 is slidably connected inside the fixed cylinder 53. The top of the extension cylinder 533... The bottom of the extension tube 533 is fixedly connected to the first spring 532. The bottom of the extension tube 533 is fixedly connected to the movable inclined plate 534. The anti-piling assembly 5 also includes several telescopic rods 54 fixedly connected to the top of the T-shaped block 344. Each of the telescopic rods 54 is provided with a second spring. The top of the telescopic rods 54 is fixedly connected to a fixed plate 541. A fixed inclined plate 542 is fixedly connected to one side of the fixed plate 541. The fixed inclined plate 542 and the movable inclined plate 534 are mutually pressed and engaged. The anti-piling assembly 5 also includes several through slots 55 opened inside the rotating tooth 42. The several through slots 55 are located between every two rows of bristles 421 and pass through the rotating tooth 42.

[0063] It should be noted that when the gas supply pipe 521 supplies gas to the fixed cylinder 53, the one-way valve 531 is in the closed state, and the input gas can drive the first spring 532 to stretch through the extension cylinder 533. When the sealing disc 511 retracts, the one-way valve 531 is in the open state, and the first spring 532 can drive the moving inclined plate 534 to rise rapidly through the extension cylinder 533. Thus, when the restraining block 23 moves from one end to the other end, the moving inclined plate 534 will not block the movement of the fixed plate 541. Furthermore, the telescopic rod 54 is equipped with a second spring inside. When the fixed plate 541 descends, the fixed plate 541 can drive the second spring inside the telescopic rod 54 to compress. When the moving inclined plate 534 is no longer in contact with the fixed plate 541, the second spring inside the telescopic rod 54 can quickly return to its original state and vibrate.

[0064] When it is necessary to prevent the cleaned particles from accumulating inside the bristles 421, during the sliding of the drive bar 343, the drive bar 343 drives the sealing disc 511 to slide inside the air supply cylinder 52 via the T-shaped bar 51. This allows the gas inside the air supply cylinder 52 to enter the fixed cylinder 53 through the air supply pipe 521. The gas then causes the extension cylinder 533 to move out and stretch the first spring 532, bringing the moving inclined plate 534 and the fixed inclined plate 542 to the same horizontal height. As the T-shaped block 344 moves the fixed plate via the telescopic rod 54... 541 moves with the fixed inclined plate 542, so that the moving inclined plate 534 presses the fixed plate 541 through the fixed inclined plate 542, thus compressing the telescopic rod 54. When the moving inclined plate 534 and the fixed plate 541 are no longer in contact, the telescopic rod 54 quickly returns to its original state, and then transmits the vibration generated by the retraction of the telescopic rod 54 to the rotating tooth 42 through the T-block 344 and the restraint block 23, so that the particles between the bristles 421 are discharged from the interior of the rotating tooth 42 through the through groove 55, thereby avoiding the continuous accumulation of particles and affecting subsequent normal use.

[0065] Working principle: When excess discharge wire 141 needs to be wound onto the surface of cable roller 14, drive motor 21 is started. Drive motor 21 drives rotating plate 212 to rotate via drive rod 211. Rotating plate 212 drives binding block 23 to rotate via drive box 22. During the rotation of binding block 23, binding block 23 drives discharge wire 141 to be wound onto the surface of cable roller 14 through opening 231, preventing excess discharge wire 141 from accumulating on the ground and becoming tangled, which could cause the operator to trip and disconnect the discharge wire 141 from the battery that needs to be charged. When the discharge wire 141 needs to be wound onto the surface of cable roller 14 in an orderly manner, during the rotation of drive box 22, cable roller 14 is wound onto the surface of cable roller 14 through teeth. The tooth 31 drives the drive gear 32 to rotate, and the drive gear 32 drives the rotating rod 34 to rotate through the transmission assembly 33. The rotating rod 34 drives the limiting rod 342 to rotate through the drive disc 341. In turn, the limiting rod 342 drives the transmission bar 343 to slide inside the limiting block 35. The transmission bar 343 drives the binding block 23 to move through the T-block 344. The binding block 23 drives the discharge wire 141 to be wound in an orderly manner on the surface of the cable roller 14 through the opening 231, thereby preventing the discharge wire 141 from always accumulating on a certain surface of the cable roller 14. When it is necessary to clean the particles on the surface of the discharge wire 141, when the transmission bar 343 drives the binding block 23 to move through the T-block 344, the binding block 23 drives the rotating tooth 42 to move. During the movement of tooth 42, the T-shaped tooth plate 41 meshes with and drives the rotating tooth 42 to rotate, causing the rotating tooth 42 to drive the bristles 421 to rotate. This allows the bristles 421 to sweep away particles from the surface of the discharge wire 141 during rotation, preventing particles from being squeezed against the surface of the discharge wire 141 after winding, which could cause scratches and affect subsequent use. To prevent the cleaned particles from accumulating inside the bristles 421, during the sliding of the transmission bar 343, the transmission bar 343 drives the sealing disc 511 to slide inside the air supply cylinder 52 via the T-shaped bar 51. This allows the gas inside the air supply cylinder 52 to enter the fixed cylinder 53 through the air supply pipe 521, thereby driving the extension... The cylinder 533 moves out and causes the first spring 532 to stretch, so that the moving inclined plate 534 and the fixed inclined plate 542 are at the same horizontal height. As the T-block 344 moves the fixed plate 541 and the fixed inclined plate 542 through the telescopic rod 54, the moving inclined plate 534 squeezes the fixed plate 541 through the fixed inclined plate 542, and the telescopic rod 54 is compressed. When the moving inclined plate 534 and the fixed plate 541 are no longer in contact, the telescopic rod 54 quickly returns to its original state, and then transmits the vibration generated by the retraction of the telescopic rod 54 to the rotating tooth 42 through the T-block 344 and the restraint block 23, so that the particles between the bristles 421 are discharged from the interior of the rotating tooth 42 through the through groove 55, thereby avoiding the continuous accumulation of particles and affecting subsequent normal use.

[0069] Perpendicularity: The perpendicularity defined in this application is not limited to an absolute perpendicular intersection (with an included angle of 90 degrees). It is permissible for non-absolute perpendicular intersections caused by factors such as assembly tolerances, design tolerances, and structural flatness. It is permissible for errors within a small angular range, such as an assembly error range of 80 to 100 degrees, which can all be understood as a perpendicular relationship.

[0070] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
