Abstract
Description
Technical Field
[0001] The present invention relates to the field of electronic products, and more specifically, to a battery and a battery compartment with a power-off protection function. Background Art
[0002] In existing batteries, since the positive and negative electrodes are exposed externally, when the positive and negative electrodes of the battery come into contact with a conductor simultaneously, it is easy to cause a short circuit of the battery. A large amount of heat will be generated inside the battery, which may lead to a rapid increase in the battery temperature. This will not only damage the internal structure of the battery, but may also cause safety accidents such as fires. In addition, the short circuit will also cause the battery power to be consumed rapidly, thereby shortening the service life of the battery.
[0003] Therefore, it is necessary to provide a battery that has no voltage on the two electrodes at both ends of the battery when the battery is placed alone and cannot discharge externally, thereby preventing the short circuit of the positive and negative electrodes of the battery to solve the above technical problems. Summary of the Invention
[0004] The purpose of the present invention is to provide a battery with a power-off protection function. When the battery is in the process of transportation or other situations without actual use, the conductive contact points of the battery itself are not charged, thereby overcoming the technical problem of accidental short circuit of the positive and negative electrodes of the battery in the prior art.
[0005] The battery with a power-off protection function includes a battery module and a housing arranged outside the battery module. The battery module is provided with two electrodes on two opposite side surfaces respectively, and the polarities of the two electrodes are opposite.
[0006] Wherein, the housing has a cover, and the battery further includes a power-off protection component. The power-off protection component is located outside the two side surfaces and is electrically connected to the two electrodes respectively to realize power supply and charging. The cover is used to close the side surface;
[0007] The power-off protection component includes:
[0008] A controlled conductive part, which includes a fixed end, a connection end and a push switch. One end of the fixed end is connected to the electrode, and the other end is connected to the push switch. One end of the connection end is connected to the push switch. The fixed end and the connection end are made of metal;
[0009] A fixed electrode plate, which is fixed on the surface of the cover facing the battery module. At least one perforation is provided on the cover, and at least a part of the fixed electrode plate is located in the perforation, so that the fixed electrode plate is exposed outside the cover;
[0010] The other end of the connection end is connected to the fixed electrode plate;
[0011] The cover is also provided with a flexible push button, which is opposite to the push switch and used to shield the push switch. When the flexible push button is pressed, it touches the push switch to make the push switch conduct.
[0012] In the present invention, after the battery is manufactured and installed, the push switch in the controlled conductive part is relative to the flexible push button on the cover. When the flexible push button is pressed or squeezed, the flexible push button presses the push switch to make the push switch conduct. At the same time, the connection end and the fixed electrode plate conduct, and the electric energy from the battery assembly is transported to the fixed electrode plate through the electrode and the controlled conductive part. A part of the fixed electrode plate is exposed on the cover, so that the two ends of the battery on the cover have electricity. When the external force applied to the flexible push button disappears, the push switch returns to the unpressed state. At this time, the push switch is cut off, and the conductive path from the electrode plate to the fixed electrode plate is disconnected, so as to achieve power-off protection.
[0013] During the transportation and placement of this battery, the flexible push button is in the unpressed state, so the fixed electrode plate on the cover itself is not charged and is relatively safe.
[0014] The battery made of this structure is not charged on its electrode plate during transportation, and can overcome the accidents caused by the accidental open circuit of the positive and negative electrodes of the battery in the prior art.
[0015] The present invention also discloses a battery compartment used in cooperation with the battery to realize charging and discharging of the battery. The battery compartment includes:
[0016] A receiving part for receiving the battery;
[0017] Two end parts, which are opposite to each other and located at both ends of the receiving part;
[0018] The two end parts are provided with protruding pressing parts and conductive contact points, and the pressing parts face the receiving part;
[0019] After the battery is placed in the battery compartment, the pressing part is relative to the flexible push button to press the flexible push button; the conductive contact point is relative to the fixed electrode plate and contacts the fixed electrode plate.
[0020] In the present invention, only when the battery is placed in the battery compartment, the flexible push button is squeezed by the protruding pressing part, so that the push switch conducts to connect the controlled conductive part and the fixed electrode plate inside the battery, and the conductive contact point contacting the fixed electrode plate can obtain electric energy from the inside of the battery. The structure is relatively simple, only the pressing part interface needs to be set, and it is only necessary to ensure that the pressing part is opposite to the flexible push button and the push switch of the battery.

[0024] The present invention will be further described and explained below in conjunction with specific embodiments and the accompanying drawings of the specification:
[0025] Please refer to Figure 1 and Figure 2 The present invention discloses a battery compartment 100 and a battery 200 for being installed in the battery compartment 100. The battery compartment 100 is used to charge the battery 200 or the battery 200 supplies power to the outside through the battery compartment 100.
[0026] Among them, the battery compartment 100 includes: a receiving portion 11 and two end portions 12.
[0027] The receiving portion 11 is used to receive the battery 200; the two end portions are opposite to each other and are located at both ends of the receiving portion 11; protruding pressing portions 121 and conductive contact points 122 are provided on the two end portions 12, and the pressing portions 121 face the receiving portion 11.
[0028] Among them, the battery 200 includes: a battery module 21 and a housing 22 provided outside the battery module 21.
[0029] Two electrodes 211 are respectively provided on two opposite side surfaces 210 of the battery module 21, and the polarities of the two electrodes 211 are opposite. The housing 22 has a cover 221. The battery 200 further includes a power-off protection component 23. The power-off protection component 23 is located outside the two side surfaces 210 and is respectively electrically connected to the two electrodes 211 to realize power supply and charging. The cover 221 is used to close the side surface;
[0030] The power-off protection component 23 includes: a controlled conductive member 231, a fixed electrode piece 232, and a flexible pressing key 233.
[0031] As Figure 3, the controlled conductive member 231 includes a fixed end 231a, a connection end 231b, and a push switch 231c. One end of the fixed end 231a is connected to the electrode 211, and the other end is connected to the push switch 231c. One end of the connection end 231b is connected to the push switch 231c. The fixed end 231a and the connection end 231b are made of metal. The fixed electrode plate 232 is fixed on the surface of the cover 221 facing the battery module 23. At least one through hole a is provided on the cover 221, and at least a part of the fixed electrode plate 232 is located in the through hole a, so that the fixed electrode plate 232 is exposed on the cover 221;
[0032] Wherein, the other end of the connection end 231b is connected to the fixed electrode plate 232. A flexible push button 233 is further provided on the cover 221. The flexible push button 233 faces the push switch 231c and is used to shield the push switch 231c. When the flexible push button 231c is pressed, it touches the push switch 231c to make the push switch 231c conduct.
[0033] After the battery 200 is placed in the battery compartment 100, the pressing portion 121 presses the flexible push button 233 relative to the flexible push button 233. The conductive contact point 122 contacts the fixed electrode plate 232 relative to the fixed electrode plate 232.
[0034] In the present invention, after the battery is manufactured and installed, the push switch 231c in the controlled conductive member 231 is relative to the flexible push button 233 on the cover 221. When the flexible push button 233 is pressed or squeezed, the flexible push button 233 presses the push switch 231c to make the push switch 231c conduct. At the same time, the connection end 231b and the fixed electrode plate 232 conduct, and the electric energy from the battery assembly 200 is transmitted to the fixed electrode plate 232 through the electrode 211 and the controlled conductive member 231. A part of the fixed electrode plate 232 is exposed on the cover 221, so that the cover 221 at both ends of the battery 200 has electricity. When the external force applied to the flexible push button 233 disappears, the push switch 231 returns to the unpressed state. At this time, the push switch 231 is cut off, and the conductive path from the electrode plate to the fixed electrode plate 232 is disconnected, thereby realizing power-off protection.
[0035] In the present invention, only when the battery 200 is placed in the battery compartment 100, the flexible push button 233 is squeezed by the protruding squeezing portion 121, so that the push switch 231 is turned on, and then the controlled conductive member 231 inside the battery and the fixed electrode plate 232 can be conducted. Only then can the conductive contact point 122 in contact with the fixed electrode plate 232 obtain electrical energy from inside the battery. The structure is relatively simple. It only needs to set the squeezing portion 121 and ensure that the squeezing portion 121 is opposite to the flexible push button 233 and the push switch 231 of the battery.
[0036] Wherein, the power-off protection component 23 further includes a bottom cover 234. The bottom cover 234 is installed on the side surface 210. The controlled conductive member 231 is fixed on the bottom cover 234 and connected to the electrode 211. The other end of the controlled conductive key 233 is opposite to the fixed electrode plate 232.
[0037] In the present invention, the controlled conductive member 231 is fixed on the side surface 210 of the battery 200 through the bottom cover 234, while the fixed electrode plate 232 and the flexible push button 233 are fixed on the cover 221. When manufacturing the battery 200 of the present invention, first, the bottom cover 234 is fixed on the side surface 210 of the battery, and the controlled conductive member 231 is fixed on the bottom cover 234. At the same time, ensure that one end of the controlled conductive member 231 is connected to the battery electrode 211, and the connection end 231b of the controlled conductive member 231 is opposite to the fixed electrode plate 232 to be installed. Then, the fixed electrode plate 232 and the flexible push button 233 are installed on the cover 221. After that, the battery 21 is passed through the housing 22 and is basically flush with the end face of the housing 22. Then, the covers 221 are installed on the two end faces of the housing 22 to seal. When the cover 221 is installed, the controlled conductive member 231 just contacts the fixed electrode plate 232. Commonly, the cover 221 and the housing 22 can be directly fixed by a snap-fastening method. The whole installation and manufacturing process is relatively simple. Except for the fixed electrode plate 232 and the flexible push button 233, no other structures of the battery are exposed, and the outside of the battery 21 is beautiful.
[0038] Wherein, the connection end 231b includes a bent portion b extending from one side of the push switch 231c and facing the fixed electrode plate 232. The bent portion b is connected to the fixed electrode plate 232. The connection end 231b has elasticity.
[0039] In the present invention, the connection end 231b is a bent structure and has elasticity. When no external force is applied, the bent portion b deflects toward the fixed electrode plate 232. When the cover 221 is installed, the fixed electrode plate 232 on the cover 221 abuts against the bent portion b. The elasticity of the bent portion b can ensure the close contact between the connection end 231b and the fixed electrode plate 232 and prevent detachment.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
