Description

Technical Field

[0001] This application relates to the field of lithium batteries, and in particular to a novel lithium battery-to-dry cell structure. Background Technology

[0002] Currently, most dry cell batteries on the market are 1.5V alkaline batteries or carbon-zinc batteries. However, alkaline batteries or carbon-zinc batteries have low energy density, and most alkaline batteries or carbon-zinc batteries are not easy to recharge, making them difficult to reuse. They are often discarded after use, which can easily cause environmental pollution. Lithium batteries have the advantages of high energy density and rechargeability, but their voltage is usually 3.7V, which cannot directly replace 1.5V dry cell batteries. Therefore, a structural component is needed to convert the voltage of lithium batteries to 1.5V. Summary of the Invention

[0003] In order to convert the voltage of a lithium battery to 1.5V, this application provides a novel lithium battery to dry cell structure.

[0004] This application provides a novel lithium-ion battery-to-dry cell structure using the following technical solution:

[0005] A novel lithium battery to dry cell structure includes a housing, a base, and a conversion assembly. The housing is snapped and fixed to the base. The housing is fixedly provided with discharge contacts, and the base is fixedly provided with discharge plates.

[0006] The conversion assembly includes a conversion shell and a conversion module. The conversion shell is disposed inside the shell, and the conversion module is fixedly disposed in the conversion shell. One output terminal of the conversion module is electrically connected to a discharge contact, and the other input terminal of the conversion module is electrically connected to a discharge plate. When the lithium battery is placed inside the conversion shell, one input terminal of the conversion module is electrically connected to the positive electrode of the lithium battery, and the other input terminal of the conversion module is electrically connected to the negative electrode of the lithium battery.

[0007] By adopting the above technical solution, when it is necessary to convert a lithium battery into a 1.5V dry cell battery, the lithium battery is placed inside the conversion casing and electrically connected to the conversion module. Thus, when the lithium battery discharges, it is converted by the conversion module, so that the voltage output from the discharge contacts and discharge plates has been converted to 1.5V, which improves the problem that lithium batteries with excessively high voltage cannot easily replace 1.5V dry cells.

[0008] Optionally, the conversion assembly further includes multiple limiting rods, each of which is rotatably connected to the conversion shell. The limiting rods are evenly distributed around the axis of the conversion shell. When the lithium battery is placed inside the conversion shell, each limiting rod is pressed and fixed against the outer peripheral surface of the lithium battery.

[0009] Optionally, the conversion assembly further includes multiple drive gears and a drive gear ring, each drive gear being rotatably connected to the conversion housing, and each drive gear being coaxially fixed to each of the limiting rods. The drive gear ring is coaxially fixedly disposed in the housing, and each drive gear meshes with the drive gear ring.

[0010] Optionally, the outer circumferential surface of the housing is provided with a through-hole rotating groove, through which the conversion housing is rotated.

[0011] Optionally, the outer peripheral surface of the conversion shell is engraved with rotational grooves.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When it is necessary to convert a lithium battery to a 1.5V dry cell battery, place the lithium battery inside the conversion case and make the lithium battery electrically connected to the conversion module. When the lithium battery discharges, it is converted by the conversion module, so that the voltage output from the discharge contacts and discharge plates is already 1.5V, which improves the problem that lithium batteries with too high voltage are not easy to replace 1.5V dry cells.

[0021] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0022] This application discloses a novel lithium-ion battery-to-dry cell structure. (Refer to...) Figure 1 and Figure 2 A novel lithium battery to dry cell structure includes a housing 1, a base 2, and a conversion component 3. A discharge contact 11 is fixedly provided on the top of the housing 1, a conversion cavity 12 is provided at the bottom of the housing 1, and a through rotating groove 13 is provided on the outer circumferential surface of the housing 1, which is connected to the conversion cavity 12.

[0023] Reference Figure 1 and Figure 3 A discharge plate 21 is fixedly installed at the bottom of the base 2, and a snap ring 22 is fixedly connected to the outer circumferential surface of the base 2. The conversion cavity 12 has a snap groove 121. When the base 2 and the housing 1 are connected, the snap ring 22 passes through and snaps into the snap groove 121, thereby realizing the snap fixation between the base 2 and the housing 1. A rotating block 23 is fixedly installed on the side of the base 2 near the housing 1. The rotating block 23 passes through the rotating groove 13 and seals the rotating groove 13. Friction marks are engraved on the outer circumferential surface of the rotating block 23, so that the base 2 can be more easily separated from the housing 1.

[0024] Reference Figure 4 The conversion component 3 includes a conversion shell 31 and a conversion module 32. The conversion shell 31 is disposed inside the housing 1, and the conversion module 32 is fixedly disposed in the conversion shell 31. One output terminal of the conversion module 32 is electrically connected to the discharge contact 11, and the other input terminal of the conversion module 32 is electrically connected to the discharge sheet 21. When the lithium battery is placed inside the conversion shell 31, one input terminal of the conversion module 32 is electrically connected to the positive electrode of the lithium battery, and the other input terminal of the conversion module 32 is electrically connected to the negative electrode of the lithium battery.

[0025] Reference Figure 4 and Figure 5 The rotating shell includes a main body 311 and a base 312, which are connected. The conversion assembly 3 also includes multiple limiting rods 33 and multiple reset torsion springs 34. Each limiting rod 33 is rotatably connected to the main body 311. Each limiting rod 33 is evenly distributed around the axis of the conversion shell 31. One end of each reset torsion spring 34 is fixedly connected to the conversion shell 31, and the other end of each reset torsion spring 34 is fixedly connected to each limiting rod 33. When the lithium battery is placed inside the conversion shell 31, each limiting rod 33 is pressed and fixed against the outer peripheral surface of the lithium battery.

[0026] Reference Figure 1 and Figure 6The housing 1 has multiple fixed protrusions 14 fixedly installed inside, and the outer peripheral surface of the main body 311 has multiple through-hole fixed grooves 3111. Each fixed groove 3111 is evenly distributed around the axis of the main body 311. Each fixed protrusion 14 passes through each fixed groove 3111 and abuts against each limiting rod 33. When the conversion housing 31 rotates around the axis of the housing 1, each fixed protrusion 14 pushes each limiting rod 33 to rotate towards the lithium battery until each limiting rod 33 is abutted and fixed against the outer peripheral surface of the lithium battery.

[0027] Reference Figure 4 The base portion 312 is fixedly connected with multiple connecting blocks 3121. When the main body portion 311 and the base portion 312 are connected, each connecting block 3121 passes through each fixing groove 3111. The outer peripheral surface of the base portion 312 is engraved with rotation marks 3122. When the user needs the main body portion 311 and the housing 1 to rotate relative to each limiting rod 33 to abut against the outer peripheral surface of the lithium battery, the user moves the base portion 312 to rotate through the rotation groove 13, thereby driving the main body portion 311 to rotate, thereby causing the main body portion 311 and the housing 1 to rotate relative to each other, thereby causing each limiting rod 33 to abut against the outer peripheral surface of the lithium battery. This makes the lithium battery to dry cell battery structure suitable for lithium batteries of different diameters, and ensures that the lithium batteries placed inside the conversion housing 31 are all fixed in the center position of the conversion housing 31.

[0028] The implementation principle of the novel lithium battery to dry cell structure in this application embodiment is as follows: When it is necessary to convert the lithium battery to a 1.5V dry cell, the lithium battery is placed inside the conversion shell 31 and electrically connected to the conversion module 32. Thus, when the lithium battery discharges, it is converted by the conversion module 32, so that when the voltage is output from the discharge contact 11 and the discharge plate 21, the voltage has been converted to 1.5V, which improves the problem that the lithium battery voltage is too high to easily replace the 1.5V dry cell.

[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
