Detailed Description
As shown in fig. 1 to 4, a battery includes a case 100, a battery cell 200, a chip 300, a case cover 400, an insulating tape 500, and a fixing collar 600.
The housing 100 is preferably a steel shell with good structural stability, and is formed into a design specification size by punching a 304 steel deep drawing material through a plurality of progressive stamping dies; an upper end of the casing 100 is open 101, the battery cell 200 occupies a main space within the casing 100 and is biased toward a lower end of the casing 100, the chip 300 is located above the battery cell 200, the casing cover 400 is located above the chip 300, and the opening 101 is closed by the casing cover 400.
A layer of insulating film 500 is laid between the chip 300 and the battery cell 200, so that direct contact between the battery cell 200 and the chip 300 can be isolated, and interference is avoided, wherein the insulating film 500 can be prefabricated on the lower end surface of the chip 300, in order to perform stable electrical connection between the chip 300 and the battery cell 200, a positive plate 200a is led out from the upper end of the battery cell 200, and the chip 300 is provided with a first connecting plate 301, wherein the first connecting plate 301 penetrates through the insulating film 500 to be connected with the positive plate 200 a; the positive plate 200a and the first connecting plate 301 both have good compression resistance, and in the packaging process, the positive plate 200a and the first connecting plate 301 are pressed on the lower end face of the insulating rubber sheet 500, so that the packaging structure is not influenced while the stable electrical connection relationship is achieved.
The fixing collar 600 is disposed along the periphery of the chip 300, and provides a space for the chip 300 in the vertical height direction, wherein the fixing collar 600 and the casing 100 are tightly fitted, and the fixing collar 600 and the casing 100 form a tight connection by using elastic pressure generated after the assembly between the fixing collar 600 and the casing 100 while the battery cell 200, the insulating adhesive sheet 500 and the chip 300 are encapsulated in the casing 100.
The hardness of the fixing collar 600 in this example is smaller than that of the housing 100, and is made of copper, for example, which has a strong plasticity and is convenient for manufacturing, and on the other hand, has a good thermal conductivity, so that the heat of the chip 300 can be sufficiently transferred and dissipated, and the chip 300 is prevented from being damaged due to the heat concentration at the chip 300.
Wherein the surface of the fixing collar 600 of the present example may be further coated with an insulating material to electrically insulate the housing 100 from the chip 300; in order to perform stable electrical connection between the chip 300 and the housing 100, a second connecting pad 302 is led out from the chip 300 and is directly pressed on the housing 100 through the fixing collar 600.
As shown in fig. 4, the preferable structure of the fixing collar 600 is that the fixing collar 600 includes an upper section 601 and a lower section 602, wherein the upper section 601 is in interference fit with the casing 100, the lower section 602 is in clearance fit with the casing 100, the upper section 601 and the lower section 602 are in a step shape, during the assembling time, the lower section 602 is first placed in the casing 100, and at this time, the lower section 602 does not generate compression deformation with the casing 100, and as the lower section 602 extends into the casing 100, the upper section 601 gradually contacts with the casing 100, and since the hardness of the upper section 601 is less than that of the casing 100, the upper section 601 is compressed and deformed, and finally, the tight fit relationship in fig. 2 is formed.
Further, in order to prevent the conductivity of the second connection piece 302 from being affected during the assembly process of the fixing collar 600, a notch 602a may be further provided on the lower section 602 for placing the second connection piece 302 so as to allow sufficient contact between the second connection piece 302 and the housing 100.
Still further, the second connecting piece 302 has a first section 302a and a second section 302b in an L shape, the first section 302a is horizontal and located on the insulating rubber 500, and is directly connected to the chip 300, and the second section 302b is vertical and located between the fixing collar 600 and the housing 100.
The lower end of the shell 100 is closed, a groove body 102 which is sunken downwards is preformed at the lower end of the shell 100, and the depth of the groove body 102 is 0.2-1.0 mm, such as 0.65mm in fig. 2; a negative plate 200b and a third connecting plate 303 connected with the negative plate 200b are led out from the lower end of the battery cell 200, and when the battery cell 200 is assembled, the third connecting plate 303 can be compressed by the battery cell 200 in the up-down direction to form an elastic supporting connection.
Specifically, the third connecting piece 303 is provided with a Z-shaped shape, as shown in fig. 2 and 3, the third connecting piece 303 includes an upper supporting piece 303a, a lower supporting piece 303b and an inclined elastic piece 303c, wherein the upper supporting piece 303a is attached to the lower end portion of the battery cell 200, the lower supporting piece 303b is attached to the inner side of the lower bottom wall of the tank body 102, the elastic piece 303c is compressed in the process of assembling the fixing collar 600 and the casing 100, the upper supporting piece 303a and the lower supporting piece 303b have larger attaching areas, and the electrical connection stability is better.
In this example, the upper end of the battery is used as the positive terminal 100a, and the lower end is used as the negative terminal 100b, and accordingly, an overvoltage and overcurrent protection circuit and a voltage stabilizing circuit may be disposed in the chip 300 to ensure the stability and continuity of the output voltage of the battery.
The positive terminal 100a of the present example is connected to the chip 300 by the terminal connection nail 103, wherein the terminal connection nail 103 is provided to penetrate the case cover 400, preferably integrally formed with the case cover 400, having a more stable structure.
Compared with the conventional charging method, in this example, the USB type charging interface 104 is disposed on the chip 300, and the housing cover 400 is disposed with a hole adapted to the charging interface 104, so as to complete charging through a quick plug, referring to fig. 3, the USB type charging interface 104 is connected to the chip 300 through the charging circuit, the chip 300 is connected to the battery cell 200 through the first connecting piece 301, and the chip 300 is connected to the battery cell 200 through the second connecting piece 302, the housing 100, and the third connecting piece 303, so as to form a stable loop, thereby completing the charging process of the battery cell 200.
The retaining collar 600 in this example provides space for the chip 300 to fit in a package, which is more effective in protecting the chip 300 than the prior art (e.g., 201510321435.0, fig. 2 b) in which the chip 300 is directly adjacent to other components, and the chip 300 is nearly completely packaged without damage during the assembly process of the battery.
The fixed lantern ring 600 in this example has played explosion-proof effect simultaneously, can be through selecting the cooperation tolerance between casing 100 and the fixed lantern ring 600, obtain the biggest axial force that the fixed lantern ring 600 can bear, bear destructive event inflation back at electric core 200, can produce the effort and destroy the tight fit relation between the fixed lantern ring 600 and the casing 100, the fixed lantern ring 600 is rushed out or the part rushes out casing 100, carry out the pressure release and lose air, and then prevent the explosion of electric core 200, need not to set up the anomalous joint structure among the prior art, make the product structure more normalized, be convenient for the shaping of battery.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to limit the scope of the invention. It will be appreciated by those skilled in the art that various modifications may be made without departing from the scope of the invention, and it is intended to cover all such modifications as fall within the true scope of the invention.
