Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic products, in particular to a battery and a battery compartment with a power-off protection function. Background Art
[0002] Because existing batteries have exposed positive and negative electrodes, a short circuit can easily occur when both electrodes come into contact with a conductor. This generates significant heat inside the battery, potentially causing it to rapidly heat up. This can damage the battery's internal structure and potentially lead to safety hazards such as fire. Furthermore, a short circuit can cause a rapid depletion of battery power, shortening the battery's lifespan.
[0003] Therefore, it is necessary to provide a battery that has no voltage on the electrodes at both ends of the battery when the battery is placed alone, and cannot discharge to the outside, thereby preventing the positive and negative electrodes of the battery from short-circuiting, so as to solve the above technical problems. Utility Model Content
[0004] The purpose of the utility model is to provide a battery with a power-off protection function. When the battery is not actually used during transportation, 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 poles of the battery in the prior art.
[0005] The battery with power-off protection function comprises a battery module and a shell arranged outside the battery module. The battery module is provided with two electrodes on two opposite sides, and the polarities of the two electrodes are opposite to each other.
[0006] The housing has a cover, and the battery further includes a power-off protection component, which is located outside the two side surfaces and is electrically connected to the two electrodes respectively to achieve power supply and charging, and the cover is used to close the side surfaces;
[0007] The power-off protection component includes:
[0008] A controlled conductive member, the controlled conductive member comprising a fixed end, a connecting end, and a push switch, one end of the fixed end being connected to the electrode and the other end being connected to the push switch, one end of the connecting end being connected to the push switch, the fixed end and the connecting end being made of metal;
[0009] a fixed electrode sheet, the fixed electrode sheet being fixed to a surface of the cover facing the battery module, the cover being provided with at least one through-hole, at least a portion of the fixed electrode sheet being located within the through-hole, such that the fixed electrode sheet is exposed from the cover;
[0010] The other end of the connecting end is connected to the fixed electrode sheet;
[0011] The cover is further provided with a flexible pressing key, which is opposite to the pressing switch and is used to shield the pressing switch. When the flexible pressing key is pressed, it triggers the pressing switch to make it conductive.
[0012] In the utility model, 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, causing the push switch to be turned on. At the same time, the connecting end and the fixed electrode sheet are turned on, and the electric energy from the battery assembly is transmitted to the fixed electrode sheet through the electrode and the controlled conductive part, and a part of the fixed electrode sheet is exposed on the cover, so that the covers at both ends of the battery have electricity; when the external force applied to the flexible push button disappears, the push switch returns to an unpressed state. At this time, the push switch is cut off, and the conductive path from the electrode sheet to the fixed electrode sheet is disconnected, thereby realizing power-off protection.
[0013] During the transportation and placement of the battery, the flexible pressing key is in an unpressed state, so that the fixed electrode sheet on the cover is not charged and is relatively safe.
[0014] The battery made of this structure does not carry electricity on its own electrode sheets during transportation, which can overcome the accidents caused by accidental disconnection of the positive and negative poles of the battery in the prior art.
[0015] The utility model also discloses a battery compartment used in conjunction with the battery to realize charging and discharging of the battery, the battery compartment comprising:
[0016] a receiving portion, the receiving portion being used to receive the battery;
[0017] two end portions, the two end portions being opposite to each other and located at two ends of the accommodation portion;
[0018] A protruding extrusion portion and a conductive contact point are provided on both ends, and the extrusion portion is arranged toward the accommodation portion;
[0019] After the battery is placed in the battery compartment, the pressing portion is opposite to the flexible pressing key to press the flexible pressing key; the conductive contact point is opposite to the fixed electrode sheet and contacts the fixed electrode sheet.
[0020] In this utility model, only when a battery is placed in the battery compartment and the flexible push button is squeezed by the protruding squeeze portion, turning on the push switch, can the controlled conductive element inside the battery and the fixed electrode sheet be connected, and the conductive contact point with the fixed electrode sheet can obtain electrical energy from the battery. The structure is relatively simple, requiring only the squeeze portion interface to be provided and ensured that the squeeze portion is aligned with the flexible push button and the push switch.

[0024] The present invention will be further described and explained below in conjunction with specific embodiments and accompanying drawings:
[0025] Please refer to Figure 1 and Figure 2 The utility model discloses a battery compartment 100 and a battery 200 for installation 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] The battery compartment 100 includes a receiving portion 11 and two end portions 12 .
[0027] The accommodating portion 11 is used to accommodate the battery 200 ; two ends are opposite to each other and are located at both ends of the accommodating portion 11 ; protruding extrusion portions 121 and conductive contact points 122 are provided on the two ends 12 , and the extrusion portions 121 are arranged toward the accommodating portion 11 .
[0028] The battery 200 includes a battery module 21 and a housing 22 disposed outside the battery module 21 .
[0029] The battery module 21 is provided with two electrodes 211 on two opposing side surfaces 210, each with opposite polarities. The housing 22 has a cover 221. The battery 200 also includes a power-off protection assembly 23, which is located outside the two side surfaces 210 and electrically connected to the two electrodes 211 to provide power supply and charging. The cover 221 is used to seal the side surfaces.
[0030] The power-off protection component 23 includes: a controlled conductive member 231 , a fixed electrode sheet 232 , and a flexible pressing key 233 .
[0031] like Figure 3The controlled conductive member 231 includes a fixed end 231a, a connecting end 231b, and a press switch 231c. One end of the fixed end 231a is connected to the electrode 211, and the other end is connected to the press switch 231c. One end of the connecting end 231b is connected to the press switch 231c. The fixed end 231a and the connecting end 231b are made of metal. The fixed electrode sheet 232 is fixed to the surface of the cover 221 facing the battery module 23. The cover 221 is provided with at least one through-hole a. At least a portion of the fixed electrode sheet 232 is located in the through-hole a, so that the fixed electrode sheet 232 is exposed from the cover 221.
[0032] Among them, the other end of the connecting end 231b is connected to the fixed electrode sheet 232; a flexible press key 233 is also provided on the cover 221, and the flexible press key 233 is opposite to the press switch 231c and is used to shield the press switch 231c. When the flexible press key 231c is pressed, it touches the press switch 231c to make the press switch 231c conductive.
[0033] After the battery 200 is placed in the battery compartment 100 , the pressing portion 121 is opposite to the flexible pressing key 233 to press the flexible pressing key 233 ; the conductive contact point 122 is opposite to the fixed electrode sheet 232 and contacts the fixed electrode sheet 232 .
[0034] In the present invention, after the battery is manufactured and installed, the press switch 231c in the controlled conductive member 231 is relative to the flexible press key 233 on the cover 221. When the flexible press key 233 is pressed or squeezed, the flexible press key 233 presses the press switch 231c, so that the press switch 231c is turned on, and at the same time, the connecting end 231b and the fixed electrode sheet 232 are turned on, and the electric energy from the battery assembly 200 is transmitted to the fixed electrode sheet 232 through the electrode 211 and the controlled conductive member 231, and a part of the fixed electrode sheet 232 is exposed on the cover 221, so that the covers 221 at both ends of the battery 200 have electricity; when the external force applied to the flexible press key 233 disappears, the press switch 231 returns to the unpressed state, at this time the press switch 231 is turned off, and the conductive path from the electrode sheet to the fixed electrode sheet 232 is disconnected, thereby achieving power-off protection.
[0035] In this utility model, only when the battery 200 is placed in the battery compartment 100 and the flexible push button 233 is squeezed by the protruding pressing portion 121, the press switch 231 is turned on, and the controlled conductive member 231 inside the battery and the fixed electrode sheet 232 are connected. The conductive contact point 122 in contact with the fixed electrode sheet 232 can then receive electrical energy from the battery. The structure is relatively simple, requiring only the pressing portion 121 to be positioned relative to the flexible push button 233 and the press switch 231.
[0036] The battery compartment 100 is provided with a wire, and the wire is electrically connected to the conductive contact point 122 .
[0037] The power-off protection component 23 further includes a bottom cover 234 , which is mounted on the side 210 . The controlled conductive member 231 is fixed to 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 sheet 232 .
[0038] In the present invention, the controlled conductive member 231 is fixed to the side 210 of the battery 200 through the bottom cover 234, and the fixed electrode sheet 232 and the flexible press key 233 are fixed to the cover 221; when making the battery 200 of the present invention, first fix the bottom cover 234 to the side 210 of the battery, and fix the controlled conductive member 231 to the bottom cover 234, while ensuring that one end of the controlled conductive member 231 is connected to the battery motor 211, and the connection end 231b of the controlled conductive member 231 is opposite to the fixed electrode sheet 232 to be installed; then install the fixed electrode sheet 232 and the flexible press key 233 on the cover 221; then pass the battery 21 through the shell 22, and basically ensure that it is flush with the end face of the shell 22; then install the cover 221 on the two end faces of the shell 22 to seal it. When the cover 221 is installed, the controlled conductive member 231 is just in contact with the fixed electrode sheet 232. The most common method is to directly fasten the cover 221 to the housing 22 by snapping. The entire installation and manufacturing process is relatively simple. In addition to the fixed electrode sheet 232 and the flexible pressing button 233, no other structure of the battery is exposed, and the battery 21 has an aesthetically pleasing appearance.
[0039] The connecting end 231b includes a bent portion b extending from one side of the push switch 231c and disposed toward the fixed electrode sheet 232. The bent portion b is connected to the fixed electrode sheet 232. The connecting end 231b is elastic.
[0040] In the present invention, the connecting end 231b is a bent structure and is elastic. When no external force is applied, the bent portion b is offset toward the side of the fixed electrode sheet 232. When the cover 221 is installed, the fixed electrode sheet 232 on the cover 221 is abutted against the bent portion b. The elasticity of the bent portion b can ensure that the connecting end 231b and the fixed electrode sheet 232 are in close contact to prevent separation.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
