Description

Technical Field

[0001] The present invention relates to the technical field of new energy batteries, and in particular to a battery casing, a battery and an electrical device. Background Art

[0002] With the development of social technology, more and more devices are becoming intelligent and electronic, and rechargeable batteries have become the energy center of these devices. Currently, most electronic products that carry rechargeable batteries use embedded batteries, which directly encapsulate lithium batteries inside the device. This type of built-in electronic product has the following two main disadvantages: first, it is difficult to replace the damaged battery, and the host needs to be replaced, resulting in a waste of resources; second, the battery cannot be disassembled and recycled when the product is discarded, which pollutes the environment.

[0003] Traditional electronic products with replaceable batteries are complicated to operate and have many parts (batteries need to be installed and the back cover needs to be tightened), such as the old-fashioned traditional flashlight that uses No. 1 dry cell batteries.

[0004] At present, traditional electronic products have the following main disadvantages: First, it is difficult to repair the damaged battery, and the host needs to be disassembled for repair. At present, the host of many electronic devices is difficult to disassemble, and many consumers directly discard the host after the host is used, resulting in a waste of resources; second, it is difficult to remove the battery when the product is discarded for classified recycling, and the battery is often discarded with the product, causing environmental pollution. Third, the volume utilization rate of the product is low. The same volume requires a battery cover, which reduces the space that can accommodate the battery, resulting in a reduction in the space that the product can actually provide energy to the battery, resulting in a decrease in the battery life of the device; fourth, the traditional remote control-style power replacement method, due to the large number of connection points of the device, causes the overall internal resistance of the energy storage component to be high. Moreover, with the latest battery bill announced in Europe, the batteries of digital products are required to be removable. Since this can protect the environment (discarding used batteries will pollute the environment) and extend the life of electronic products, traditional electronic products with built-in batteries are directly discarded after the device cannot be used. There are two main reasons: first, many electronic products are glued during production for the sake of beauty and stability, which is not conducive to subsequent disassembly and recycling; second, disassembling these products requires professional knowledge, many users lack the corresponding professional knowledge, and the cost of repairing them at repair shops is high. Therefore, in the future, the battery of electronic products will be separated and made into a detachable independent component. This will not only increase the service life of electronic products, but also because the battery circuit is separated from the circuit of the whole machine, when the battery is damaged, the user can replace a battery without professional knowledge to determine whether it is the host or the battery that is damaged. When the device is damaged, the battery can be directly removed and recycled separately.

[0005] In the future, it will be a new technological trend to make the energy storage part of traditional electronic products detachable as a whole. The electronic products include but are not limited to handheld fans, flashlights, atomizers, shavers, laser pens and other devices.

[0006] Therefore, the present technology designs a detachable battery with a simple structure. The battery does not have a complicated detachable structure, and the battery can be detached by utilizing simple friction force in physics. Summary of the invention

[0045] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] It should be understood that when used in this specification and the appended claims, the terms "include" and "comprises" indicate the presence of described features, integers, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or combinations thereof.

[0047] It should also be understood that the terms used in this description of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, unless the context clearly indicates otherwise, the singular forms of "a", "an" and "the" are intended to include plural forms.

[0048] See also Figure 1-18 The embodiment of the present invention provides a battery housing. The battery housing includes a housing 1, a positive terminal 2 and a negative terminal 3; a base 11 is fixedly provided at the bottom of the housing 1, and the outer diameter of the base 11 is larger than the outer diameter of the housing 1; at least one pressure-bearing portion 12 is provided on the outer surface of the housing 1; the positive terminal 2 and the negative terminal 3 are respectively provided at the top of the housing 1. The specific description of each component is as follows:

[0049] The cross-section of the shell 1 is any one of circular, elliptical, and prismatic. It should be noted that the cross-section of the shell 1 is any one of circular, elliptical, and prismatic, which is only an example. Those skilled in the art may also adopt a shell 1 with other cross-sectional shapes, which does not exceed the protection scope of the present invention. In this embodiment, the cross-section of the shell 1 is circular and is made of any one of steel, aluminum, polycarbonate (PC for short), polyethylene (PE for short), and polytetrafluoroethylene (PTFE). The shell 1 and the internal chemical system constitute a complete single battery cell. In one embodiment, the shell 1 can be loaded with a complete core body, such as a battery cell, a stacked core, or a rolled core. The shell 1 plays a role in fixing and fully sealing the internal electrochemical system. A positive terminal 2 and a negative terminal 3 are respectively provided on the top of the shell 1, that is, the positive terminal 2 and the negative terminal 3 are installed on the same side of the shell 1. In one embodiment, the positive terminal 2 and the negative terminal 3 adopt a concentric circle structure with positive inside and negative outside to effectively avoid reverse connection of positive and negative electrodes, or the positive terminal 2 and the negative terminal 3 are distributed on the left and right, and the distances from the center of the circle are unequal, forming a non-centrally symmetrical shape, which can effectively avoid reverse connection of positive and negative electrodes. In this embodiment, the number of the pressure-bearing parts 12 is multiple, and the multiple pressure-bearing parts 12 are evenly spaced and arranged around the shell 1. The pressure-bearing parts 12 are arranged on the outer surface of the shell 1 and on one side of the shell 1 close to the bottom. In one embodiment, the number of the pressure-bearing parts 12 is one, for example: Figure 13-14The pressure-bearing portion 12 is a strip-shaped structure, and the radial height of the pressure-bearing portion 12 on the housing 1 is 0.05 mm, and it is distributed along the circumference of the housing 1. It can be understood that the closer the pressure-bearing portion 12 is to the base 11, the easier it is for the housing 1 to be separated from the housing of the electronic device. For another example: See Figure 15-16 The pressure-bearing part 12 is a sheet-like structure, distributed along the circumference of the shell 1. It can be understood that the greater the thickness of the pressure-bearing part 12, the more difficult it is to separate the shell 1 from the shell of the electronic device. Usually, the minimum thickness of the pressure-bearing part 12 is 0.05mm. When the battery made of the shell 1 is inserted into the electronic device, the pressure-bearing part 12 of the raised part is squeezed and deformed, so that the battery is firmly embedded in the shell of the electronic device, and the battery will not fall out without a certain external force. It should be noted that those skilled in the art can flexibly adjust the number, shape and position of the pressure-bearing part 12 on the shell 1, thereby changing the embedding effect, for example: the pressure-bearing part 12 is a continuous thread shape, and for example: the pressure-bearing part 12 is arranged at the shell 1 near the base 11, and the pressure-bearing part 12 is connected to the base 11, so that the shell 1 can be easily inserted / pulled out of the shell of the electronic device; the pressure-bearing part 12 is arranged at the shell 1 away from the base 11, which can enhance the firmness of the shell 1 in the shell of the electronic device. The base 11 can be made of an insulating material, or the base 11 can be made of steel or aluminum, and is fixedly connected to the bottom of the shell 1. In one embodiment, the base 11 and the shell 1 are integrally die-cast, and the positive terminal 2 is a cover member with a convex shape at the center, which is made of a conductive metal material. The negative terminal 3 is a member with an annular notch at the center, which is made of a conductive metal material. The annular notch is connected to the connecting port of the microphone (gas sensor) on the circuit board. The radial width of the notch is within 1 mm, and the surface tension of the liquid can prevent the liquid from entering the circuit board. When used on the atomizer, the liquid at the connecting port can be sucked out. Usually, insulating material is filled between the positive terminal 2 and the negative terminal 3 to prevent the positive terminal 2 from contacting the negative terminal 3 and causing a short circuit. It should be noted that the length and shape of the base 11 are not specifically limited. It can be understood that the longer the length of the base 11, the more convenient it is for the user to pull it out. See. Figure 17-18 , Fig.17 A schematic diagram of a housing structure provided by an embodiment of the present invention, Fig.18 A schematic diagram of another housing structure provided by an embodiment of the present invention.

[0050] In a specific implementation, the interior of the shell 1 may also be loaded with a power storage module, such as: a capacitor battery cell, an aluminum shell battery cell, a polymer battery cell, a winding core, a stacked core, etc. The shell 1 is used to fix the power storage module, and is electrically connected to the power storage module through the positive terminal 2 and the negative terminal 3 respectively. In actual scenarios, according to the distribution position of the positive and negative terminal ears of the battery cell, the positive terminal 2 can be connected to the positive terminal ear by pre-setting a conductive lead in the shell 1, or the negative terminal 3 can be connected to the negative terminal ear by pre-setting a conductive lead. The shell 1 made of conductive metal material can also be directly connected to the negative terminal ear of the battery cell, so that the entire shell 1 can be used as a negative terminal. When the shell 1 is used in an atomizer, a circuit board is also provided inside the shell 1, and a start-up module such as a gas sensor microphone is provided on the circuit board. Further, the positive terminal 2 is provided with a hollow structure, and the diameter of the hollow structure is less than 1 mm. In this embodiment, the larger the surface tension of the liquid, the closer the diameter of the hollow structure is to 1 mm, and the smaller the surface tension of the liquid, the farther the diameter of the hollow structure is from 1 mm. It should be noted that the calculation principle of the surface tension of the liquid can be determined by referring to existing data, and the present invention does not make specific restrictions on this. The diameter of the hollow structure is equal from bottom to top, or the diameter of the hollow structure gradually increases from bottom to top (the place close to the gas sensor is the bottom, and the place far from the gas sensor is the top). The positive terminal 2 designed in this way, because the liquid has surface tension, water droplets will form on the metal surface, and will not enter the interior of the shell 1 without external force. Therefore, when the diameter of the hollow structure of the positive terminal 2 is relatively small, when the surface tension is greater than the gravity of the liquid, the liquid stays on the surface of the positive terminal 2 and does not enter the interior of the shell 1 along the hole. In addition, the hollow structure is made into a structure with equal diameters from bottom to top, or a structure with a diameter that gradually increases from bottom to top. Even if the liquid is subjected to forces other than gravity, the liquid can be discharged by external force each time it is started, thereby protecting the sensor. Further, the hollow structure is made into a structure with a gradually increasing aperture from bottom to top, which increases the difficulty of liquid entering the sensor and reduces the difficulty of liquid discharge. Since the gas sensor works by sensing changes in gas, it must be connected up and down to conduct gas to control the start and closure of the circuit. Therefore, it is impossible to make the gas sensor completely waterproof and oil-proof. The microphone of the gas sensor will be damaged if it is immersed in liquid for a long time. If the hollow structure is made into a structure with a hole diameter larger than the hole diameter at the top, water and oil will enter the interior of the housing 1 and cannot escape, eventually damaging the gas sensor.

[0051] The technical effects that the battery housing can achieve are as follows:

[0052] The connection method between the electronic product and the battery is simplified. The positive terminal 2 and the negative terminal 3 are arranged on the same side to avoid the battery short circuit and fire caused by the reverse installation of the battery. The structure of the shell 1 is simple. The top of the shell 1 is electrically connected to the electronic product. The base 11 at the bottom of the shell 1 can be pulled to separate the shell 1 from the electronic product, thereby simplifying the structure of the detachable battery.

[0053] Continue to see Figure 1-18 In this embodiment, a charging module 4 is further included. A charging port 13 is also provided on the outer surface of the shell 1 . The charging module 4 is arranged in the shell 1 , and the charging port 13 is connected to the charging module 4 .

[0054] Specifically, the charging module 4 includes a circuit board, on which are disposed a plurality of components for charging, such as a charging interface (Micro USB, Type-C, Lightning, and pin contact), a charging port 13 is reserved on the housing 1, and the charging port 13 is an opening of the housing 1. In this embodiment, the charging module 4 is disposed inside the housing 1 and on one side of the housing 1 near the top. In one embodiment, see Fig.10 The charging module 4 and the charging port are respectively arranged on one side of the shell 1 near the bottom. For example, the charging port 13 is arranged on the base 11, so that the battery can be charged without being removed from the product. In some other embodiments, the base 11 and the shell 1 are detachably connected, the base 11 covers the lower opening of the shell 1, and the charging port 13 is arranged on the base 11.

[0055] Furthermore, the housing 1 is further provided with an air hole 14 and an air passage 15 , and the air passage 15 is communicated with the air hole 14 and the charging port 13 respectively.

[0056] Specifically, an air hole 14 can be reserved at the bottom of the shell 1, and the inside of the shell 1 is connected to the outside through the air hole 14, so that gas conduction between the inside of the shell 1 and the outside is realized. In one embodiment, the shell 1 is used in an atomizer, and the air hole 14 is added to the bottom of the shell 1 to conduct the gas generated by the atomizer to prevent the gas generated by the atomizer from being blocked in the shell 1. The air channel 15 is provided on the outer surface of the shell 1. It should be noted that those skilled in the art can flexibly adjust the shape of the air channel 15 and the distribution position on the shell 1 to realize that the charging module 4 inside the shell 1 is connected to the outside of the shell 1.

[0057] Furthermore, the housing 1 is further provided with a limiting portion 16 , and the negative terminal 3 is arranged on the limiting portion 16 .

[0058] Specifically, the limiting portion 16 is on the inner wall of the shell 1. In this embodiment, the negative terminal 3 is a ring-shaped component with a gap at the center and is made of a conductive metal material. The preset limiting portion 16 can prevent the internal structure of the battery from being damaged when the negative terminal 3 is installed.

[0059] Furthermore, it also includes a sleeve 5 , the shell 1 and the pressure-bearing portion 12 are respectively embedded in the sleeve 5 , and the outer diameter of the sleeve 5 is less than or equal to the outer diameter of the base 11 .

[0060] Specifically, the sleeve 5 is used to be installed on an electrical device. In one embodiment, the sleeve 5 is fixedly mounted on an electrical device such as an atomizer. The outer diameter of the housing 1 is smaller than the inner diameter of the sleeve 5. The housing 1 and the sleeve 5 are detachably connected through the pressure-bearing portion 12 of the housing 1. In one embodiment, the distance between the outer diameter of the housing 1 and the inner diameter of the sleeve 5 is in the range of 0.05 mm to 0.4 mm. When the distance between the outer diameter of the housing 1 and the inner diameter of the sleeve 5 is 0.05 mm, the elastic pressure-bearing portion 12 can be deformed and snapped into the sleeve 5. Without the action of external force, the housing 1 and the sleeve 5 have a high-strength connection stability. When an external force is applied, the housing 1 can be easily removed from the sleeve 5. The outer diameter of the base 11 is greater than the outer diameter of the sleeve 5, and the outer diameter difference between the base 11 and the sleeve 5 is ≤0.8mm. For example, after the battery housing is embedded in the sleeve 5, the outer diameter difference between the base 11 and the sleeve 5 is 0.8mm, and a 0.8mm force point is formed at the joint between the base 11 and the sleeve 5. The user can hold the sleeve 5 with one hand and pull the force point outward with the other hand to achieve quick separation from the housing 1 and the sleeve 5. For another example, the outer diameter difference between the base 11 and the sleeve 5 is 0mm, and the length of the base 11 can be increased adaptively. The user can hold the sleeve 5 with one hand and pull the base 11 outward with the other hand to achieve quick separation from the housing 1 and the sleeve 5. In some other embodiments, the base 11 can also reserve an annular groove, and the rope is set on the annular groove of the base 11, and then the housing 1 is pulled out of the electrical device by holding the rope. The rope is set on the annular groove to provide a more solid force point, so that the battery can be quickly separated from the electrical device. The specific numerical settings of the outer diameter of the shell 1 and the inner diameter of the sleeve 5 can be determined according to the material of the shell 1. When the shell 1 is made of one or more of metal materials such as alloy materials, steel, aluminum, etc., the outer diameter of the shell 1 is close to the inner diameter of the sleeve 5, and the radial height range of the pressure-bearing part 12 on the shell 1 is 0.05-0.15mm, usually 0.1mm; when the shell 1 is made of plastic, resin and rubber materials, the outer diameter of the shell 1 is far away from the inner diameter of the sleeve 5, and the radial height range of the pressure-bearing part 12 on the shell 1 is 0.15mm-0.35mm, usually 0.3mm.

[0061] Furthermore, the base 11 is provided with a pull ring 111 .

[0062] Specifically, see Fig.11The pull ring 111 and the base 11 can be formed by integral die-casting, or an axial hole is reserved in the base 11, and the pull ring 111 is passed through the axial hole to achieve a fixed connection between the pull ring 111 and the base 11. The pull ring 111 is used to more conveniently pull the housing 1 to separate the battery from the electrical product. It should be noted that the pull ring 111 is a structure for assisting disassembly. Considering that the user includes a group of users with weak strength and does not have enough strength to remove the battery from the electronic device, in some other embodiments, see Fig.12 , there is also provided an I-shaped pull ring 17, which is sleeved inside the I-shaped pull ring 17 through a rope, and the housing 1 can be separated from the electrical product by pulling the rope.

[0063] Furthermore, the width of the pressure-bearing portion 12 gradually increases from top to bottom.

[0064] Specifically, the top of the shell 1 is the upper side, and the bottom of the shell 1 is the lower side. Usually, the top of the shell 1 enters the electrical equipment first, and the width of the pressure-bearing part 12 gradually increases from top to bottom to form a wedge shape. The wedge is a solid object used to strengthen, support or maintain a fixed position. It is mostly used to insert into mortise and tenon joints or gaps to fix or block the connection. The wedge-shaped pressure-bearing part 12 can effectively strengthen the connection between the shell 1 and the electrical equipment, and make it easier to embed the battery into the casing of the electronic device.

[0065] Furthermore, the radial height of the pressure-bearing portion 12 on the housing 1 is in the range of 0.05 to 0.35 mm.

[0066] Specifically, multiple pressure-bearing parts 12 are evenly distributed on the side of the shell 1. The radius of the shell 1 is r, and the distance range from the pressure-bearing part 12 to the axis of the shell 1 is within r+0.05mm~r+0.35mm. For example: the radial height of the pressure-bearing part 12 on the shell is 0.3mm, and the distance between the outer diameter of the shell 1 and the inner diameter of the sleeve 5 is 0.2mm. The pressure-bearing part 12 can be fully squeezed between the shell 1 and the sleeve 5 to achieve fixation of the shell 1 and the sleeve 5 to avoid loosening and detachment.

[0067] Typically, the pressure-bearing portion 12 is made of elastic material.

[0068] Specifically, the elastic material includes silicone, styrene-butadiene rubber, chloroprene rubber, polyurethane, propylene-based elastomer, and polyester elastomer. In one embodiment, when the elastic pressure-bearing part 12 is installed in the sleeve 5, the wear of the sleeve 5 on the pressure-bearing part 12 can be reduced, which can effectively increase the number of times the battery can be disassembled. In addition, the pressure-bearing part 12 is squeezed by the housing 1 and the sleeve 5, which can improve the connection stability between the battery and the sleeve 5.

[0069] In one embodiment, the pressure-bearing portion 12 is made of a heat shrink tube, generally a heat shrink tube made of PVC material. PVC material is a plastic material with insulating properties. The pressure-bearing portion 12 is formed by stacking multiple layers of PVC material after heat shrinkage.

[0070] The present invention also provides a battery, comprising the battery casing as described in any one of the above embodiments.

[0071] Specifically, when the battery is loaded into an electrical device, the pressure-bearing portion 12 on the side of the shell 1 will clamp the battery into the outer shell of the electrical device, so that the battery will not slide out of the outer shell of the electrical device without the action of external force. Under the action of external force, since the battery and the electrical device are not locked, they can be easily separated from the outer shell of the electrical device. This battery structure is simple and simplifies the structure of the detachable battery.

[0072] The present invention further provides an electrical device, comprising a battery as described in any one of the above embodiments, wherein the battery is used to provide electrical energy.

[0073] Specifically, the electrical device includes a mobile phone, an atomizer, a flashlight, etc. In one embodiment, the sleeve 5 can be fixedly mounted on the electrical device to achieve a detachable connection between the battery and the sleeve 5.

[0074] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
