Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-10, a specific embodiment of the present invention is a combined mobile power supply, including a power supply body 1, where the power supply body 1 is provided with an electrical input end 2 and an electrical output end 3, and a battery cell 4 is disposed in the power supply body 1;

the power supply body 1 side still is provided with two or more than two connecting portion 5 respectively, still be provided with tie point 6 on the connecting portion 5 respectively, can fix together through connecting portion 5 with adjacent power supply body 1, adjacent power supply body 1 can the electrical connection together through tie point 6. The magnet on the connecting portion, upper portion both sides magnetic pole are opposite, and lower part both sides magnetic pole is also opposite, and adjacent portable power source direction all faces up like this and when magnet polarity corresponds, just can magnetism adsorb the connection.

The magnets are arranged below the connection points, if the sides of the two mobile power supplies with opposite magnetic polarities are close to each other, but one of the two mobile power supplies is reversed, the magnets are adsorbed together, but the contacts cannot be contacted (the phenomenon that the positive and negative electrodes of two similar batteries are connected with each other to form a direct short circuit is avoided). To avoid short circuits when attached to horizontal metal, the connection points on the same side are one slightly above the magnet and the other slightly below the magnet.

In order to make the connection more stable, be provided with magnet 7 on connecting portion 5, power supply body one side is provided with two connecting portion 5, and 1 opposite side of power supply body also is provided with two connecting portion 5, and the connecting portion 5 magnetic pole of homonymy is the same, and the connecting portion 5 magnetic pole of both sides is opposite.

In order to ensure the stability of the electrical connection, the connection point 6 is a metal contact or a spring probe. The spring probe is suitable for being made into a part higher than the magnet, and the metal contact is suitable for being made into a part lower than the magnet; because the spring probe has certain elasticity, the spring probe and the combination of metal contact can effectively guarantee the stability of electricity connection.

As shown in fig. 1, the magnet 7 is higher than the surface of the power supply body 1, and the connection points 6 on the same side are one higher than the magnet 7 and the other connection point 6 is lower than the magnet 7. The upper left connecting point is a metal contact (slightly lower than the height of the magnet), and the upper right connecting point is a metal probe (slightly higher than the height of the magnet); the lower right connection point is a metal contact (slightly lower than the height of the magnet), and the lower left connection point is a metal probe (slightly higher than the height of the magnet). With this arrangement, even if the metal sheet is attached to the metal sheet by accident, short circuit does not occur due to the difference in the height of the contacts.

In order to ensure that the magnetic attraction force achieves a strong effect, the magnet 7 is flush with or slightly protrudes from the surface of the power supply body 1. The magnetic force is inversely proportional to the square of the distance, with the closer the magnet is, the greater the magnetic force.

For convenience, the electric output end 3 and the electric input end 2 are both magnetic force interfaces, and both the electric output end 3 and the electric input end 2 can be connected to a magnetic force data line 12 with the magnetic force interfaces or a magnetic force adapter 13.

The reset switch and the electric input end structure are integrated better, and the space is saved; the electrical input end will also be less vulnerable to damage when dropped because it will retract into the housing.

In order to enable the connection between the magnetic data line and the mobile power supply to be more compact and stable, a threaded opening 11 is further formed in the electric input end 2, a threaded sleeve 14 is arranged on the magnetic data line 12, and the threaded opening 11 is fixedly connected with the threaded sleeve 14 correspondingly.

The power supply comprises a power supply body 1, and is characterized in that a protection control module 15 is arranged in the power supply body 1 and comprises a battery cell protection module and a control chip. The electricity input end still electricity is connected with the module 16 that charges, electricity output end still electricity is connected with the module 17 that steps up, still set up the display module who is used for showing the electric quantity on the power body, the display module can be for LED lamp or electronic screen. The display module, the charging module 16, the boosting module 17 and the battery cell are respectively electrically connected with the protection control module 15; all the connection points are connected with the battery cell through the protection control module. Even if the short circuit takes place for the tie point, also can avoid electric core short circuit and damage through electric core protection module.

For example: the connection points on the two connection parts on the upper part of the power supply body are used as positive electrodes and are electrically connected with the positive electrodes of the battery cells, and for safety, the connection points are not directly connected with the two poles of the battery, but the two poles of the battery are connected with the protection control module; the tie points on two connecting portions of the lower portion of the power supply body serve as negative poles and are electrically connected with the negative poles of the battery cells, the two poles of the battery are connected to the battery cell protection module, and the tie points are welded to the battery cell protection module. After adjacent portable power sources are connected through the connecting portion, the battery cores are equivalently connected in parallel. When the parallel charging and discharging are carried out, only the electric cores are connected in parallel, and the boosting and charging modules are not used, so that the charging efficiency is guaranteed, and the charging time is prolonged.

When the portable power supply is used, 1 or a plurality of portable power supplies are carried according to the use requirement, the single weight is light, the capacity is large, 1-3 portable power supplies can be used in one day in daily use, and 3-6 portable power supplies can be carried in business trips. When a plurality of mobile power supplies are carried, the mobile power supplies are electrically connected together through a connection point, a user can charge the mobile power supplies through a data line, and manual switching is not needed if one electric quantity is used up; the mobile power supply in the hand can be separated and lent to other people for independent use. When the electric quantity of the plurality of mobile power supplies is exhausted, all the mobile power supplies can be charged through one data line without being charged one by one, and the magnetic attraction is connected in parallel and can be charged together. Compare traditional many calories of displacement power supply cabinet, this application also need not to correspond one by one and puts appointed charging card position on, and the operation is nimble simple more.

The magnetic attraction type portable power source is simple and compact in structure, the plurality of portable power sources can be simply and effectively magnetically attracted and electrically connected together to form a portable power source with larger capacity, the portable power sources can be used singly or together, and the use methods are flexible and various; the magnets in the application can be connected in a zero distance mode, and when combined magnetic adsorption connection is conducted, the magnetic force is large, and the connection strength is stable; meanwhile, the probability of short circuit caused by error connection can be effectively reduced by adopting reasonably arranged connection points and magnets and by virtue of the relation between magnetic polarity and high and low positions; after adjacent portable power source electricity is connected simultaneously, can use a charging wire to charge together during charging, the operation of charging is more convenient.
