Description

Technical Field

[0001] The present invention relates to the technical field of battery charging and discharging, and more specifically, to a charging and discharging device and method for a storage battery. Background Art

[0002] The storage battery charging and discharging device can automatically select a suitable charging mode and parameters according to the type, capacity, and current power of the storage battery, and achieve constant current charging and constant voltage charging. Secondly, it has a discharge management function:

[0003] The device can simulate the actual discharge conditions of the storage battery and perform discharge tests in a constant current or constant power mode.

[0004] In the existing published literature, the patent with the patent announcement number CN209730877U discloses an automatic charging and discharging device for a storage battery. This technology is connected to a current sensor and a voltage sensor through a charging jack circuit; a control box with a code scanning area and a coin slot area is arranged on the upper side of the upper cover. The current sensor and voltage sensor at the charging port position of the device are used to detect whether the storage battery is fully charged. After detecting that it is fully charged, the motor drives the spur gear slide bar to slide, and the spur gear slide bar drives the auxiliary jack to move, pulling out the charging plug to give the charging port to other vehicle owners, making it more convenient to use. However, the following problems still exist when using this technology.

[0005] During the charging and discharging process of the storage battery by the charging and discharging device of the storage battery, the connecting terminal part needs to be inserted into the charging and discharging port of the storage battery. There are multiple charging and discharging ports on the storage battery, and long-term insertion will cause wear on the charging and discharging terminal part of the storage battery, resulting in poor contact in multiple charging and discharging of the storage battery. And for maintenance, it is necessary to wait for the maintenance personnel to disassemble the entire charging and discharging equipment internally and repair them one by one. The maintenance cost is relatively high and it is more time-consuming and laborious. This makes it difficult to automatically achieve uniform force synchronous wrapping repair of the charging and discharging terminal parts of multiple storage batteries. The charging and discharging self-repair not only has a high cost but also low efficiency. Summary of the Invention

[0006] To achieve the above object, the present invention provides the following technical solution: A charge and discharge device for a storage battery, comprising a charge and discharge protection shell, a support frame, and a linkage screw.

A connection terminal is inserted into the gap surrounded by all the energized elastic pieces, and the connection terminal is inserted into the charge and discharge protection shell. A controller is fixedly installed on one side of the charge and discharge protection shell. The top end of the conductive steel wire rope is fixedly connected with a support block, and the support block is fixedly connected to the charge and discharge circuit board.

[0008] When this technology is used for charge and discharge, there is a problem of poor contact between the connection terminal and the energized elastic piece. The reduction motor drives the linkage screw to rotate, and the linkage screw drives a plurality of socket blocks to move synchronously downward under the action of the screw transmission force. The plurality of socket blocks respectively drive a plurality of insulating pressure strips to move synchronously downward, and the socket pressing block moves downward along the outer wall of the conductive steel wire rope. The conductive steel wire rope shrinks and squeezes around the outer wall of a plurality of energized elastic pieces. The conductive steel wire rope can synchronously and equally forcefully wrap and repair a plurality of energized elastic pieces, and a plurality of energized elastic pieces can equally forcefully press against the outer wall of the connection terminal, so that a plurality of energized elastic pieces and the connection terminal continue to conduct electricity.

[0009] Preferably, a charge-discharge guiding, wrapping and repairing assembly is provided below the conductive head; the charge-discharge guiding, wrapping and repairing assembly includes a support ring arranged below the conductive head, and the support ring is fixedly connected to the charge-discharge circuit board.

[0010] When the present technology is used for charge and discharge, when the conductive steel wire rope contracts while wrapping the outer wall of the energized elastic piece, the support ring supports the support column, the arc-shaped block supports the two guiding strips, and the guiding strip guides and limits one side of the outer wall of the conductive steel wire rope. The limiting strip limits and supports the other side of the outer wall of the conductive steel wire rope, enabling multiple energized elastic pieces to be synchronously and evenly force-wrapped and repaired at the specified positions.

[0011] Preferably, two reinforcing blocks are fixedly installed at the bottom end of the inner wall of the charge-discharge protective case, and a uniform-speed guiding assembly is installed at the top end of each reinforcing block; the uniform-speed guiding assembly includes a guiding column fixedly installed at the top end of the reinforcing block, and a socket guide rail is slidably connected to the outer wall of the guiding column.

At the same time, the charge-discharge protective case supports the two reinforcing blocks. At the same time, the socket guide rail drives the socket support plate to move downward, and the sensing shaft makes the connecting block move downward, and the connecting block will drive the speed sensor to move downward synchronously. The outer wall of the friction roller makes rolling friction contact with the inner wall of the charge-discharge protective case, and the sensing shaft rotates on the sensing end of the speed sensor until the sensing speed of the speed sensor is the same as the speed set by the controller. Ensure that multiple insulating pressure strips can move downward evenly under force at the specified speed, the insulating pressure strip drives the socket pressing block to move downward evenly under force at the specified speed, and the conductive steel wire rope can evenly force and evenly speed to synchronously wrap and repair multiple energized elastic pieces.

[0013] A charge-discharge method for a storage battery, the method comprising the following steps:

[0014] Step 1: When in charge and discharge use, if charging is required, connect one end of the connection terminal to the power supply device. After detecting the charging signal through the charge and discharge circuit board, charge and store energy in the storage battery.

The socket pressing block moves downward along the outer wall of the conductive steel wire rope, and the conductive steel wire rope contracts and squeezes around the outer walls of multiple energized elastic pieces. When the torque force value sensed by the torque force sensor is the same as the value set by the controller, the reduction motor is turned off by the controller, and synchronous equal-force wrapping can be realized on the outside of multiple energized elastic pieces, so that the positions of the charge and discharge energized elastic pieces of multiple storage batteries can be automatically wrapped and repaired with equal force synchronously. The charge and discharge self-repair not only has lower cost, but also greatly improves the charge and discharge self-repair efficiency;

The conductive steel wire rope can be accurately limited and wrapped in the outer wall grooves of multiple energized elastic pieces and perform synchronous equal-force wrapping and repair according to the specified position. The charge and discharge self-repair not only has lower cost, but also greatly improves the charge and discharge self-repair efficiency;

[0021] The present invention adopts a constant-speed guiding component. The insulating strip will drive the socket guide rail to move downward synchronously. The socket guide rail drives the socket support plate to move downward, and the socket support plate drives the sensing shaft to move downward. The friction roller is driven to move downward by the sensing shaft. The outer wall of the friction roller makes rolling friction contact with the inner wall of the charge and discharge protection shell. The friction roller drives the sensing shaft to rotate until the sensing speed of the speed sensor is the same as the speed set by the controller, ensuring that multiple insulating strips can move downward with uniform force at a specified speed. The conductive steel wire rope can evenly apply force and wrap and repair multiple energized elastic pieces at a uniform speed. The charge and discharge self-repair not only has a lower cost, but also has higher accuracy and a significantly improved efficiency of charge and discharge self-repair.

[0041] One end of the sensing shaft 26 is fixedly connected coaxially with a friction roller 27, and a speed sensor 28 is installed at the other end of the sensing shaft 26.

[0042] The usage method of the charge and discharge device of the storage battery of the present invention is as follows:

[0043] First of all, when the present invention is used for charge and discharge, one end of the connection terminal 14 is connected to the power supply device, and then the other end of the connection terminal 14 is inserted into the gap surrounded by a plurality of energized elastic pieces 9. The connection terminal 14 is conductively connected to the energized elastic pieces 9. The connection terminal 14 conducts electricity to the energized elastic pieces 9, the energized elastic pieces 9 conduct electricity to the conductive head 10, and the conductive head 10 conducts electricity to the charge and discharge circuit board 11. In this way, after the charge and discharge circuit board 11 detects the charging signal, the storage battery 13 is charged and stored with energy. When one end of the connection terminal 14 is docked to the electrical equipment, the charge and discharge circuit board 11 conducts the electrical energy of the storage battery 13 to the conductive head 10, the conductive head 10 conducts to a plurality of energized elastic pieces 9, the energized elastic pieces 9 conduct to the connection terminal 14, and the connection terminal 14 conducts to the electrical equipment, realizing the discharge function. In this way, the storage battery 13 forms a charge and discharge function.

[0044] Secondly, when the present invention performs charge and discharge synchronous equal force wrapping and repair, when the connection terminal 14 is inserted into the energized elastic piece 9 multiple times, the internal arc-shaped block 19 will become loose, resulting in a problem of poor contact between the connection terminal 14 and the energized elastic piece 9. The controller 15 is used to start the reduction motor 4, and the reduction motor 4 drives the linkage screw 3 to rotate. The linkage screw 3 rotates inside the support frame 2, and the linkage screw 3 drives a plurality of socket blocks 5 to move synchronously downward under the action of the screw transmission force.

[0045] Multiple socket blocks 5 drive multiple insulating pressure strips 6 to move downward synchronously. The insulating pressure strips 6 drive multiple socket pressing blocks 7 to move downward, and the socket pressing blocks 7 move downward along the outer wall of the conductive steel wire rope 8. At the same time, the storage battery 13 supports the charge and discharge circuit board 11, the charge and discharge circuit board 11 supports the support block 16, and the support block 16 supports the conductive steel wire rope 8. In this way, the conductive steel wire rope 8 shrinks and squeezes around the outer wall of multiple energized elastic pieces 9. At the same time, the torque force sensor 12 senses the torque force of the linkage screw 3, and the conductive steel wire rope 8 can perform synchronous and uniform force wrapping repair on multiple energized elastic pieces 9. Multiple energized elastic pieces 9 can uniformly squeeze on the outer wall of the connection terminal 14. Thus, multiple energized elastic pieces 9 continue to conduct electricity with the connection terminal 14, avoiding the problem of poor contact between the connection terminal 14 and the energized elastic piece 9, and can perform synchronous and uniform force wrapping repair on the energized elastic pieces 9 outside multiple connection terminals 14.

[0046] At the same time, when the present invention performs charge and discharge guiding and wrapping repair, when the conductive steel wire rope 8 shrinks and wraps around the outer wall of the energized elastic piece 9, the charge and discharge circuit board 11 supports the support ring 17, the support ring 17 supports the support column 18, the support column 18 supports the arc-shaped block 19, and the arc-shaped block 19 supports two guiding strips 20. The guiding strips 20 guide and limit one side of the outer wall of the conductive steel wire rope 8. At the same time, the arc-shaped block 19 supports two limiting strips 21, and the limiting strips 21 limit and support the other side of the outer wall of the conductive steel wire rope 8. The conductive steel wire rope 8 can be accurately limited and wrapped in the outer wall groove of multiple energized elastic pieces 9, enabling multiple energized elastic pieces 9 to perform synchronous and uniform force wrapping repair according to the specified position, and the automatic repair effect of charge and discharge faults is better.

[0047] At the same time, when the present invention performs uniform speed guiding, when the insulating pressure strip 6 moves downward, the insulating pressure strip 6 drives the socket guide rail 24 to move downward synchronously. The socket guide rail 24 slides downward along the outer wall of the guide post 23. At the same time, the charge and discharge protective shell 1 supports two reinforcing blocks 22, and the reinforcing blocks 22 support the guide post 23 to increase the stability of the guide post 23. At the same time, the socket guide rail 24 drives the socket support plate 25 to move downward, the socket support plate 25 drives the sensing shaft 26 to move downward, and the sensing shaft 26 causes the connection block 29 to move downward, and the connection block 29 drives the speed sensor 28 to move downward synchronously.

[0048] The friction roller 27 is driven to move downward by the sensing shaft 26, and the outer wall of the friction roller 27 makes rolling friction contact with the inner wall of the charge and discharge protection shell 1, so that the friction roller 27 drives the sensing shaft 26 to rotate. The sensing shaft 26 rotates on the sensing end of the speed sensor 28 until the sensing speed of the speed sensor 28 is the same as the speed set by the controller 15. Ensure that the multiple insulating strips 6 can move downward with uniform force at the specified speed, the insulating strips 6 drive the socket pressing blocks 7 to move downward with uniform force at the specified speed, and the conductive steel wire ropes 8 can wrap and repair the multiple energized elastic pieces 9 with uniform force and at a uniform speed. The torque force sensor 12 senses the torque force of the linkage screw 3. When the torque force value sensed by the torque force sensor 12 is the same as the value set by the controller 15, the controller 15 turns off the reduction motor 4. The conductive steel wire ropes 8 can wrap and repair the multiple energized elastic pieces 9 with uniform speed and uniform force, ensuring that the multiple energized elastic pieces 9 can be evenly attached to the outer wall of the connection terminal 14 to achieve the conductive restoration connection of charge and discharge.
