The terminology used herein in the description of the disclosure is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.

Electronic devices such as mobile phones and tablet computers have become essential scientific and technological products in the life, study and entertainment processes of people. With the diversified development of the application scenes of the electronic equipment, the battery adopted by the electronic equipment has higher safety performance requirements.

The battery, as the most representative energy storage device in the new energy field, occupies an irreplaceable position in the power supply device of the electronic equipment. When the battery has abnormal conditions, such as the temperature of the battery is too high, a large amount of gas is generated in the battery, so that the internal gas pressure of the battery is increased sharply. If the generated gas can not be discharged in time and exceeds the pressure bearing capacity of the battery, the battery explodes. Particularly, the steel shell battery has high structural strength and good mechanical load bearing capacity, but when the steel shell battery is in abnormal conditions and explodes, great harm can be caused. Therefore, an explosion-proof device is required to be disposed on the case of the battery to prevent the battery from exploding.

Based on this, this disclosure provides a battery protector, battery and electronic equipment, through set up protection through-hole and protection component on this battery for the battery can smooth pressure release when inside atmospheric pressure is greater than the default, avoids the explosion, is favorable to improving electronic equipment's security performance.

For a better understanding of the battery guard of the present disclosure, a battery to which the battery guard is applied and an electronic device to which the battery is applied will be explained below.

As shown in fig. 1-4. In some embodiments of the present disclosure, an electronic device 10 is provided, which includes a power consumption unit 100 and a battery 200, wherein the battery 200 is connected to the power consumption unit 100 to provide power for the power consumption unit 100. Battery 200 includes a core assembly 2100, an electrolyte, and a battery guard 2200. The battery guard 2200 includes a battery case 2210, the battery case 2210 having a receiving cavity 2211 and being provided with a guard through-hole 2212. The electrolyte and the electric core assembly 2100 of the battery 200 are disposed in the accommodating cavity 2211. The battery guard 2200 also includes a guard assembly 2230. The shield assembly 2230 includes a resilient seal 2220, a clamp member 2231, a tension member 2232, and a connecting member 2233 disposed through the shield through-hole. At least a portion of the resilient seal 2220 is disposed in the protective through-hole 2212. The clamping member 2231 is arranged outside the battery case 2210, the tightening member 2232 is arranged inside the battery case 2210 and connected to the inner side wall 2213 of the battery case 2210, the tightening member 2232 is connected with the clamping member 2231 through the connecting member 2233, and the elastic sealing member 2220 is sleeved outside the connecting member 2233 and at least partially clamped between the clamping member 2231 and the battery case 2210. The tensioning member 2232 is a resilient tensioning member and tensions the clamping member 2231 into the receiving cavity 2211 to seal the protective through-hole 2212 with the resilient seal 2220. When the air pressure in the accommodating cavity 2211 is greater than a preset value, the elastic sealing member 2220 can open the protection through hole 2212, so that the accommodating cavity 2211 is communicated with the outside.

When the battery 200 is in a normal operation state, the clamping member 2231 disposed outside the battery housing 2210 and the tightening member 2232 disposed inside the battery housing 2210 are connected by the connecting member 2233 to clamp the elastic sealing member 2220. Also, the elastic tension 2232 is connected to the inner side wall 2213 of the battery case 2210, and the clamping member 2231 is tensioned in the direction of the inside of the battery case 2210, so that the clamping member 2231 presses the elastic seal 2220. The elastic sealing member 2220 provided between the holder 2231 and the battery case 2210 is slightly deformed to seal the protection through-hole 2212, ensuring the sealability of the battery 200. When the battery 200 state is unusual, when the atmospheric pressure in holding chamber 2211 is greater than the default promptly, the atmospheric pressure in holding chamber 2211 acts on protection component 2230, with protection component 2230 back-opened from former sealed position, elastic sealing element 2220 opens protection through-hole 2212, make holding chamber 2211 and external intercommunication carry out the pressure release, the atmospheric pressure in holding chamber 2211 descends, thereby avoid battery 200 to explode because of holding chamber 2211 internal pressure is too big, ensure that the atmospheric pressure in holding chamber 2211 is in the safety range. In battery protection device 2200 that can safe pressure release was arranged in to electric core subassembly 2100 and electrolyte of battery 200, guaranteed the normal operation of electric core subassembly 2100 and electrolyte, and then made battery 200 can be steadily for the power supply of power consumption unit 100, be favorable to improving electronic equipment 10's security performance.

When the battery 200 is in a sealed state, the air pressure in the accommodating cavity 2211 is lower than the air pressure outside. The external air pressure is applied to the holder 2231, further pressing the elastic sealing member 2220, thereby enhancing the sealability of the battery 200.

It should be noted that the electronic device 10 may include, but is not limited to, a mobile phone, a tablet computer, a notebook computer, a smart watch, a new energy automobile, and the like.

Specifically, the electronic device 10 may include a handheld device, a vehicle-mounted device, a cellular phone (cellular phone), a smart phone (smart phone), a Personal Digital Assistant (PDA) computer, a tablet computer, a portable computer, a laptop computer (laptop computer), a vehicle-mounted computer, and other electronic devices 10 having the battery 200 built therein.

The power consumption unit 100 includes, but is not limited to, electrical components such as a CPU, a camera module, a display screen, a sensor, and a speaker.

Specifically, in some embodiments, the holder 2231 may be configured as a circular sheet or an elongated strip, and the elastic seal 2220 has a suitable contact area to generate sufficient pressure. The tensioning member 2232 may be an elastic member such as an elastic sheet or rubber, and generates a tensile force on the elastic sealing member 2220 through deformation. The shape of the tension member 2232 is designed according to an actual use situation, for example, the tension member 2232 is designed according to the shape of the elastic sealing member 2220, the structure of the battery case 2210, the shape of the protection through hole 2212, and the like. The shielding through-hole 2212 may have a generally cylindrical shape (as shown in fig. 5) or a truncated cone shape. The elastic seal 2220 may be T-shaped or cylindrical with an outer diameter larger than the diameter of the protection through hole so as to press and seal the cylindrical protection through hole, and the elastic seal 2220 abuts against the outer side wall 2214 around the protection through hole 2212 or is in interference fit with the peripheral side wall of the protection through hole to perform sealing. The elastic sealing element 2220 may also be formed in a truncated cone shape in cooperation with the truncated cone-shaped protection through hole, and may be sealed by interference fit with the peripheral side wall of the protection through hole. Clamping member 2231 and connecting member 2233 may be made of a rigid material such as steel, so as to ensure the pressing effect thereof on resilient seal 2220. The elastic sealing element 2220 may be formed by directly molding elastic rubber such as silicone rubber or rubber, or by wrapping an elastic layer around a rigid material such as a gasket. The present disclosure does not specifically limit the structure and materials of the shield assembly 2230.

In some embodiments, as shown in fig. 4 and 5, the tensioning member 2232 includes a bar spring 2234, a first end of the bar spring 2234 is connected to the battery case 2210, and a second end is connected to the connecting member 2233, so as to tension the clamping member 2231 via the connecting member 2233. In this way, the bar-shaped elastic pieces 2234 can pull the holder 2231, thereby generating a pressing effect on the elastic sealing member 2220 and enhancing the sealability of the battery 200. Moreover, the bar-shaped elastic sheet 2234 is in a bar shape, so that the thickness space in the accommodating cavity 2211 can be saved, and the battery 200 can be thinned conveniently.

Further, the resilient seal 2220 can also be repositioned by the resilient strip 2234 to a position that seals the shield through-hole 2212. In this way, the elastic sealing element 2220 is returned to the position for sealing the protection through hole 2212 from the position for opening the protection through hole 2212, so that the battery 200 can maintain the sealing property after the pressure is released, thereby ensuring the normal operation and supplying power to the power unit 100.

In some embodiments, the elastic sealing member 2220 seals the protection through hole 2212, and the second end of the bar-shaped elastic piece 2234 and the battery case 2210 have a deformation gap therebetween in the radial direction of the protection through hole 2212. Thus, when the protection component 2230 is pushed open by the gas in the accommodating cavity 2211, the bar-shaped elastic sheet 2234 may have a sufficient deformation space, so that the elastic sealing element 2220 can completely open the protection through hole 2212, and the pressure relief efficiency is high.

It should be noted that the tensile force of the strip-shaped elastic sheet 2234 pulling the clamping member 2231 is F1, the pushing force generated by the air pressure in the accommodating cavity 2211 acting on the protecting component 2230 to push outwards is F2, and the pressure of the external air pressure acting on the clamping member 2231 is F3. When F2 < F1+ F3, the resilient seal 2220 seals the shielded through-hole 2212. When F2 > F1+ F3, the resilient seal 2220 opens the shielded through-hole 2212. When the elastic sealing element 2220 opens the protection through hole 2212 and F2 is less than or equal to F1+ F3, the elastic sealing element 2220 is reset to the position for sealing the protection through hole 2212 through the strip-shaped elastic sheet 2234.

Thus, when the battery 200 normally works, the elastic sealing element 2220 slightly deforms under the combined action of the tension F1 and the pressure F3 to press the battery case 2210 on the peripheral side of the protection through hole 2212, so as to seal the protection through hole 2212, thereby preventing external moisture and impurities from entering the accommodating cavity 2211 from the gap between the elastic sealing element 2220 and the protection through hole 2212, and keeping the accommodating cavity 2211 in a normal working state. When the battery 200 is out of order, the air pressure in the accommodating cavity 2211 is greatly increased and exceeds a preset value. At this time, the pushing force F2 is greater than the sum of the pulling force F1 and the pressing force F3, and the pushing force F2 acting on the protection component 2230 pushes the protection component 2230 open to the outside, so that the elastic seal 2220 clamped between the clamping member 2231 and the tightening member 2232 opens the protection through hole 2212, and the excess atmospheric pressure in the accommodating cavity 2211 can be discharged from the protection through hole 2212. Then, as the air pressure in the accommodating cavity 2211 decreases, the pushing force F2 acting on the protection assembly 2230 decreases until the pushing force F2 is less than or equal to the sum of the pulling force F1 and the pressing force F3, and the protection assembly 2230 returns under the combined action of the pulling force F1 and the pressing force F3 until the elastic sealing element 2220 returns to the state of being pressed by the clamping element 2231, thereby sealing the protection through hole 2212 again. In the above process, the external moisture and impurities cannot enter the accommodating cavity 2211 all the time, so as to ensure the normal operation of the battery 200.

The electrolyte in the battery has the characteristics of high activity, inflammability and the like, and a large amount of inflammable gas is generated inside the battery under abnormal conditions of overcharge, short circuit and the like of the battery. The battery protection device 2200 of the present disclosure can rapidly discharge the inflammable gas in the accommodating cavity 2211 when the pressure is released, and simultaneously, the temperature in the accommodating cavity 2211 is reduced, and the explosion of the battery 200 is avoided.

In some embodiments, referring to fig. 4 and 5, the elastic sealing member 2220 includes an elastic gasket 2221 and a plug body 2222 fixedly connected to the elastic gasket 2221, the elastic gasket 2221 is sandwiched between the holder 2231 and the battery housing 2210, and the plug body 2222 is inserted into the protection through hole 2212. In this way, the elastic gasket 2221 can be sufficiently in contact with the battery case 2210 around the protection through hole 2212, and the sealing performance of the elastic seal 2220 can be enhanced. The plug 2222 functions as a positioning member to facilitate the installation of the elastic sealing member 2220.

Further, the plug 2222 is clearance fit with the protection through hole 2212. Therefore, when the battery 200 is decompressed, the elastic gasket 2221 and the battery shell 2210 are slightly separated, and the gas in the accommodating cavity 2211 can be directly and quickly released from the gap between the plug-in body 2222 and the protection through hole 2212, so that the decompression efficiency is high. The small separation distance between the elastomeric seal 2220 and the shield through-hole 2212 allows the elastomeric seal 2220 to be quickly repositioned. Moreover, during pressure relief, part of the plug body 2222 can still be retained in the protection through hole 2212, so that the matching and positioning between the elastic sealing element 2220 and the protection through hole 2212 are ensured, and accurate reset is realized.

Alternatively, in some embodiments, as shown in fig. 4 and 5, the elastic sealing member 2220 is provided with a mounting hole 2223 penetrating the elastic gasket 2221 and the plug body 2222, the connecting member 2233 is inserted into the mounting hole 2223, and the connecting member 2233 and the clamping member 2231 are sealingly connected with the elastic sealing member 2220. In this way, the connection between the connecting member 2233 and the elastic sealing member 2220 can be stabilized, so that the clamping of the elastic sealing member 2220 by the clamping member 2231 and the tensioning member 2232 is more reliable, and the elastic sealing member 2220 can be ensured to seal the protection through hole 2212 well. In addition, the connecting member 2233 and the clamping member 2231 are hermetically connected to the elastic sealing member 2220, so that external moisture and impurities are prevented from entering the accommodating cavity 2211 through gaps between the clamping member 2231 and the connecting member 2233 and the elastic sealing member 2220, and the sealing performance of the battery protection device 2200 is further ensured.

The clamping member 2231 and the connecting member 2233 may be connected to the elastic sealing member 2220 in a sealing manner by injection molding or adhesive bonding, which is not limited in this disclosure.

Alternatively, in some embodiments, as shown in fig. 4 and 5, the clamping member 2231 and the connecting member 2233 form a rivet structure 2235, one end of the rivet structure 2235 being fixedly connected to the tension member 2232 and clamping the resilient seal 2220. Thus, the rivet structure 2235 can firmly clamp the elastic sealing element 2220, and the rivet structure 2235 is simple in structure, easy to implement and low in cost.

The rivet structure 2235 can directly nail the tension member 2232 to form a flange, and the back hook tension member 2232 is fixed. The tail portion of the rivet structure 2235 and the tension member 2232 may be fixed by gluing or screwing.

Optionally, in some embodiments, the shield assembly 2230 is an electrode assembly and is insulated from the cell housing 2210 by an elastomeric seal 2220. Alternatively, referring to fig. 2, battery guard 2200 further includes an electrode assembly 2240 disposed in insulation with battery case 2210, and electrode assembly 2240 is disposed in battery case 2210 in spaced relation to guard assembly 2230. The protection assembly 2230 is directly adopted as an electrode assembly, and the elastic sealing member 2220 plays an insulating role to ensure the safety of the battery 200 during use, so that the protection assembly 2230 can play an explosion-proof role and can also be used as an electrode to conduct electricity, thereby realizing the integration of functions, optimizing the structure of the battery 200, reducing the installation steps and saving the cost. Alternatively, the battery 200 maintains the original electrode assembly 2240, and the original production platform can be directly applied without modifying the original related design of the connection between the inside of the battery and the electrode.

Specifically, in some embodiments, as shown with reference to fig. 2, 3, and 5, battery housing 2210 includes end cap 2215 and housing 2216, with a protective through-hole 2212 provided in end cap 2215, and/or housing 2216. In this manner, the machining of the shield throughbore 2212 and the assembly of the shield assembly 2230 with the elastomeric seal 2220 is facilitated.

Further, the electrode assembly 2240 is generally disposed at the end surface of the end cap 2215 or the housing 2216, the electrode assembly 2240 protrudes from the battery case 2210 with a distance, the shield assembly 2230 and the elastic sealing member 2220 also protrude from the battery case 2210 with a distance, and the shield assembly 2230 and the electrode assembly 2240 are disposed at the same end of the battery case 2210, so that the length of the battery 200 can be reduced, and the installation space of the battery 200 in the electronic device 10 can be saved.

In some embodiments, battery housing 2210 includes at least one end cap 2215 and a housing 2216, which are sealingly assembled to form a receiving cavity 2211. End cap 2215 can be manufactured separately and assembled with shield assembly 2230 and elastomeric seal 2220, which is finally assembled with housing 2216 for ease of assembly and installation.

In some embodiments, the battery housing 2210 includes a first shell and a second shell that forms a receiving cavity 2211 in sealing fit with the first shell, and the protection through hole 2212 is disposed on the first shell and/or the second shell. Thus, the arrangement of the protection through holes 2212 can be performed according to the actual structural design of the applied electronic device 10, and the flexibility is high.

Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include at least one of the feature. In the description of the present disclosure, "a plurality" means at least two, e.g., two, three, etc., unless explicitly specifically limited otherwise.

In the present disclosure, unless otherwise explicitly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly, e.g., as meaning fixedly connected, detachably connected, or integral with; can be mechanically or electrically connected; they may be directly connected or indirectly connected through intervening media, or they may be interconnected within two elements or in a relationship where two elements interact with each other unless otherwise specifically limited. The specific meaning of the above terms in the present disclosure can be understood as a specific case by a person of ordinary skill in the art.

In the present disclosure, unless otherwise expressly stated or limited, the first feature "on" or "under" the second feature may be directly contacting the first and second features or indirectly contacting the first and second features through an intermediate. Also, a first feature "on," "over," and "above" a second feature may be directly or diagonally above the second feature, or may simply indicate that the first feature is at a higher level than the second feature. A first feature "under," "beneath," and "under" a second feature may be directly under or obliquely under the second feature, or may simply mean that the first feature is at a lesser elevation than the second feature.

It will be understood that when an element is referred to as being "fixed," "disposed," "secured" or "disposed" to another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. Further, when one component is considered to be "fixedly connected" to another component, the two components may be fixed by way of detachable connection, or may be fixed by way of non-detachable connection, such as socket connection, snap connection, integrally formed fixation, welding, etc., which can be realized in the conventional art, and is not cumbersome.
