Description

Technical Field

[0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a battery capable of preventing reverse insertion of positive and negative electrodes. Background Art

[0002] Polymer lithium battery is an advanced form of lithium-ion battery. Compared with traditional liquid lithium battery, polymer lithium battery has many obvious advantages such as high energy density, smaller size, ultra-thin, lightweight and high safety. They usually use lithium alloy as positive electrode, polymer conductive material as negative electrode, and organic solvent as electrolyte.

[0003] The polymer lithium battery contains electrode terminals, which are divided into positive and negative electrodes. In the prior art, there is no protection device for the positive and negative electrodes of the battery, while some chargers are equipped with automatic protection devices to prevent the positive and negative electrodes from being connected in reverse. Usually, when the positive and negative electrodes are connected in reverse, the charging switch is automatically disconnected. The cost of such chargers with automatic protection devices is relatively high, and users cannot promptly detect and correct the reverse connection of the electrodes. Secondly, when the lithium battery is plugged in for use, the positive and negative ears will be stuck in the ports of the electrical equipment. During the plugging and unplugging process, due to space limitations, the positive and negative electrodes are easily bent during operation, or the ports and the positive and negative electrodes are excessively worn due to the shaking of the battery and the electrical equipment, which affects the battery life and has poor stability in use. Summary of the invention

[0004] In order to overcome the above-mentioned defects, the present invention provides a battery that prevents the positive and negative poles from being inserted reversely, which solves the problem that the positive and negative electrodes of the battery have no protective device. When the lithium battery is plugged in and used, the positive and negative pole ears will be stuck in the ports of the electrical equipment. During the plugging and unplugging process, due to space limitations, the positive and negative poles are easily bent during operation, or the ports and the positive and negative poles are excessively worn due to the shaking of the battery and the electrical equipment, which affects the battery life and has poor stability in use.

[0006] By adjusting the plugging angle of the positive or negative ear, the battery can be plugged in and used conveniently, and the plugging work can be prevented from being affected by limited space, thereby preventing the positive or negative ear from bending. After the plugging work is completed, due to the shaking of the polymer lithium battery body or the electrical equipment, the two connecting seats can move relative to each other through the telescopic rod, and cooperate with the force of the buffer spring to play a buffering role for the positive and negative ears, weakening the force generated by the polymer lithium battery body or the electrical equipment on the connection part, reducing structural wear, ensuring the battery life and improving the stability of use;

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. In the present invention, the lower plug-in box is sleeved on the positive electrode sheet or the negative electrode sheet so that the positive electrode sheet or the negative electrode sheet is located in the lower conductive cover, and then the locking assembly is operated to clamp it in the card slot in the top cover to achieve the purpose of locking the lower plug-in box, and the positive electrode ear or the negative electrode ear is installed in the upper plug-in box and fixed by fastening bolts, so that the positive electrode ear or the negative electrode ear is plugged into the upper conductive cover. Since the two conductive covers are connected by a flexible connecting wire, the two conductive covers can be connected, and the purpose of connecting the positive electrode sheet and the positive electrode ear, and the negative electrode sheet and the negative electrode ear can be achieved. When using the battery, the connector is used to connect the electrical equipment or the wires on the positive electrode ear and the negative electrode ear are removed, and the positive electrode ear and the negative electrode ear are inserted into the terminal of the electrical equipment. In the mouth, because the lower plug-in box and the upper plug-in box are connected to the connecting seat through a pin shaft, the connecting seat and the upper plug-in box can deflect freely, so that the plug-in angle of the positive ear or the negative ear can be adjusted, which is convenient for plugging and using the battery and prevents the plug-in work from being affected by limited space, thereby causing the positive ear or the negative ear to bend. After the plug-in work is completed, due to the shaking of the polymer lithium battery body or the electrical equipment, the two connecting seats can move relative to each other through the telescopic rod, and cooperate with the force of the buffer spring to play a role in buffering the positive ear and the negative ear, thereby weakening the force generated by the polymer lithium battery body or the electrical equipment on the connecting part, reducing structural wear, ensuring the battery life while improving the stability of use.

[0020] 2. In the present invention, by squeezing the handles in the locking assembly, the two handles respectively drive the two card blocks to approach each other until the card blocks are out of the card connection state with the card slot, and then the mounting seat and the lower plug-in box can be removed from the polymer lithium battery body, so that the positive electrode sheet and the negative electrode sheet are out of the conductive assembly and exposed to the outside, so as to facilitate the maintenance or disassembly of the positive electrode sheet and the negative electrode sheet. When installing the lower plug-in box, the conductive cover in the lower plug-in box is sleeved on the positive electrode sheet or the negative electrode sheet. In this process, the inclined surface of the bottom of the card block contacts the top of the card slot. As the mounting seat is continuously pressed down, the two card blocks can slide in the sliding hole and approach each other. The lower plug-in box is locked with the positive electrode sheet or the negative electrode sheet, thereby improving the convenience of operation and the conduction stability between the conduction component and the positive electrode sheet or the negative electrode sheet. The positive electrode ear and the negative electrode ear are installed in the upper plug-in box. Because the positive electrode ear is a cross-shaped design and the negative electrode ear is a straight-line design, the positive electrode ear and the negative electrode ear are distinguished by changing the structural shape. The cross shape and the straight-line shape represent the positive and negative electrode symbols. Therefore, the positive and negative electrodes of the battery can be clearly distinguished to prevent the positive and negative electrodes from being inserted in reverse.

The ear plate 112 is hinged to the connection seat 111 through the pin 113. Since the lower plug-in box 4 and the upper plug-in box 5 are connected to the connection seat 111 through the pin 113, the connection seat 111 and the upper plug-in box 5 can be freely deflected, which is convenient for adjusting the plug-in angle of the positive ear 6 or the negative ear 7;

The limiting column 17 is T-shaped and is slidably connected in the limiting groove 18. When the two connecting seats 111 move relative to each other, the upper connecting seat 111 can drive the limiting column 17 to slide in the limiting groove 18 of the lower connecting seat 111, thereby supporting and connecting the two connecting seats 111 and preventing misalignment during the movement of the two connecting seats 111.

[0032] Two grooves 12 and two wire grooves 13 are provided in the deflection assembly 11, and the two wire grooves 13 are located between the two grooves 12. A conduction assembly 14 is provided in the two opposite wire grooves 13, and the conduction assembly 14 includes two conductive covers 141, which are respectively installed in the upper plug-in box 5 and the lower plug-in box 4, the positive electrode ear 6 or the negative electrode ear 7 is plugged into the upper conductive cover 141, and the positive electrode sheet 3 or the negative electrode sheet 24 is plugged into the lower conductive cover 141. Two flexible connecting wires 142 are connected between the two conductive covers 141, and the flexible connecting wire 142 passes through the through hole 15 and the middle part is located in the wire groove 13. Because the conductive cover 141 is provided, and the two conductive covers 141 are connected through the flexible connecting wire 142, the two conductive covers 141 can be conducted, and the purpose of connecting the positive electrode sheet 3 and the positive electrode ear 6, and the negative electrode sheet 24 and the negative electrode ear 7 can be achieved;

[0033] A through hole 15 is provided in the wire groove 13, the top of the conduction component 14 passes through the through hole 15 and is installed in the upper plug-in box 5, the bottom of the conduction component 14 passes through the through hole 15 and is installed in the lower plug-in box 4, the positive electrode sheet 3 and the negative electrode sheet 24 are plugged into the bottom of the conduction component 14, and a buffer component 16 is installed in the two opposite grooves 12, and the buffer component 16 includes a telescopic rod 161, and the two ends of the telescopic rod 161 are respectively fixed to the inner walls of the two opposite grooves 12, and the telescopic rod 161 is outer-mounted with a buffer spring 162, and the end of the buffer spring 162 is fixedly connected to the inner wall of the groove 12. Through the mutual cooperation between the telescopic rod 161 and the buffer spring 162, the two connecting seats 111 can move relative to each other through the telescopic rod 161, and cooperate with the force of the buffer spring 162 to play a role in buffering the positive ear 6 and the negative ear 7, thereby weakening the force exerted by the polymer lithium battery body 1 or the electrical equipment on the connecting part;

[0034] A mounting seat 20 is fixed to the bottom of the lower plug-in box 4, and sliding holes 21 are respectively provided on both sides of the mounting seat 20. A locking component 22 is installed in the sliding hole 21. A card slot 23 is provided in the top cover 2 at a position corresponding to the locking component 22. The bottom end of the locking component 22 is clamped in the card slot 23, and an isolation membrane 19 is provided in the top cover 2. The locking component 22 includes a card block 221. The bottom of the card block 221 is designed in a barb shape, and the cross-sectional shape of the card block 221 is designed in a cross shape. The card block 221 is slidably connected in the sliding hole 21. Because the bottom of the card block 221 is in a barb shape, it can be firmly embedded in the card slot 23 to prevent the card block 221 from detaching from the card slot 23. Because the cross-sectional shape of the card block 221 is in a cross shape, the stability of the horizontal movement of the card block 221 in the sliding hole 21 is improved, and the card block 221 will not deviate.

[0036] The working principle of the present invention is:

[0037] When in use, the conductive cover 141 in the lower plug-in box 4 is sleeved on the positive electrode sheet 3 or the negative electrode sheet 24. During this process, the inclined surface of the bottom of the block 221 contacts the top of the slot 23. As the mounting seat 20 continues to press down, the two blocks 221 can slide in the slide hole 21 and approach each other until the mounting seat 20 contacts the bottom of the inner wall of the top cover 2. The block 221 is supported by the elastic force of the support spring 223, so that the block 221 can be embedded in the slot 23, thereby realizing the connection between the lower plug-in box 4 and the positive electrode sheet 3. For the purpose of locking the positive electrode sheet 3 and the negative electrode sheet 24, the positive electrode ear 6 or the negative electrode ear 7 is installed in the upper plug-in box 5 and fixed by tightening the bolt 10, so that the positive electrode ear 6 or the negative electrode ear 7 is plugged into the upper conductive cover 141. Since the two conductive covers 141 are connected by the flexible connecting wire 142, the two conductive covers 141 can be connected, so that the positive electrode sheet 3 and the positive electrode ear 6, the negative electrode sheet 24 and the negative electrode ear 7 can be connected. When the battery is used, the connector 9 is used to connect the electrical equipment or remove the positive electrode ear 6 and the negative electrode. The positive ear 6 and the negative ear 7 are inserted into the port of the electrical equipment. Since the lower plug-in box 4 and the upper plug-in box 5 are connected to the connection seat 111 through the pin 113, the connection seat 111 and the upper plug-in box 5 can be freely deflected, so that the plug-in angle of the positive ear 6 or the negative ear 7 can be adjusted. After the plug-in work is completed, due to the shaking of the polymer lithium battery body 1 or the electrical equipment, the two connection seats 111 can move relative to each other through the telescopic rod 161, and cooperate with the force of the buffer spring 162 to play To buffer the positive ear 6 and the negative ear 7, and weaken the force exerted on the connection part by the polymer lithium battery body 1 or the electrical equipment, when taking out the lower plug-in box 4, squeeze the handle 222 in the locking assembly 22, so that the two handles 222 respectively drive the two card blocks 221 to approach each other until the card blocks 221 are out of the card connection state with the card slot 23, and then the mounting seat 20 and the lower plug-in box 4 can be removed from the polymer lithium battery body 1, so that the positive electrode sheet 3 and the negative electrode sheet 24 are out of the conductive assembly 14 and exposed to the outside.
