Description

Technical Field

[0001] This utility model relates to the field of battery-related technology, and in particular to an assembly casing for a 1.5V lithium-to-dry battery. Background Technology

[0002] Currently, most dry cell batteries on the market are 1.5V alkaline batteries or carbon-zinc batteries, but they have low energy density and are not rechargeable. 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, namely the assembly casing for lithium-to-dry cell batteries, which can convert the voltage of lithium batteries to 1.5V.

[0003] For example, the existing patent publication number CN216354379U discloses a structure for converting a lithium battery to a dry cell battery by connecting a screw and a nut. Because this utility model is divided into modules, the entire structure is easy to assemble and maintain. It can be adjusted according to usage requirements, reducing the overall production cost and improving the reliability of use.

[0004] However, in the process of using the lithium-to-dry battery assembly casing disclosed in the above patent, when the charging interface is not in use, dust, moisture and other impurities can easily enter the interior of the charging interface, causing corrosion and damage to the charging interface, resulting in poor contact and affecting the normal charging of the lithium-to-dry battery. Therefore, we propose an assembly casing for a 1.5V lithium-to-dry battery to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an assembly shell for a 1.5V lithium-to-dry battery, which can solve the problem that in the existing assembly shells for lithium-to-dry batteries, when the charging interface is not in use, dust, moisture and other impurities can easily enter the interior of the charging interface, causing corrosion and damage to the charging interface, resulting in poor contact and affecting the normal charging of the lithium-to-dry battery.

[0007] To solve the above technical problems, this utility model provides an assembly shell for a 1.5V lithium-to-dry battery, which adopts the following technical solution: it includes a shell and a ring, the ring is movably fitted on the outer ring of the top of the shell, a notch is fixedly opened on the side of the ring, a charging interface is placed inside the notch, a protective component is provided on the outer ring of the ring, and a voltage reduction component is provided inside the ring.

[0008] The protective assembly includes a fixing ring, which is fixedly disposed on the outer ring of a circular ring. A sliding groove is fixedly formed inside the fixing ring, and the sliding groove penetrates the upper surface of the fixing ring. A slider is movably disposed inside the sliding groove. A movable plate is fixedly disposed on the top of the slider. A rubber plate is fixedly disposed on the side of the movable plate near the circular ring. The rubber plate is movably fitted with the outer wall of the circular ring, and the lower surface of the rubber plate is movably fitted with the upper surface of the fixing ring. The height of the upper surface of the rubber plate is the same as the height of the upper surface of the circular ring.

[0009] Preferably, a heat dissipation cavity is fixedly provided in the middle of the rubber plate.

[0010] Preferably, the movable plate has a first anti-slip texture fixedly provided on the side away from the rubber plate, and a second magnetic plate is fixedly provided on both sides of the movable plate. Two first magnetic plates are fixedly provided on the outer wall of the ring, and the two first magnetic plates are respectively located on both sides of the slide groove.

[0011] Preferably, the top edge of the outer shell is rounded, and a tapered elastic ring is provided at the bottom of the ring, with the tapered elastic ring and the outer shell having an interference fit.

[0012] Preferably, a second anti-slip texture is fixedly provided on the outer ring of the fixing ring.

[0013] Preferably, the step-down assembly includes a circuit board, which is fixedly disposed on the inner wall of the top of the housing. The charging interface is fixedly disposed on one side of the bottom of the circuit board. A positive terminal of a dry cell battery is disposed in the middle of the top of the circuit board. Circuit elements are disposed on the other side of the bottom of the circuit board. An installation cavity is disposed inside the housing for placing a lithium battery.

[0015] In summary, this utility model has at least one of the following beneficial effects:

[0016] 1. By installing the protective components, when the charging interface is not in use, pushing the movable plate will cause the slider to slide inside the groove, which in turn will cause the rubber plate to move on the outer wall of the ring. The rubber plate will cover the charging interface, preventing dust, moisture and other impurities from entering the interior of the charging interface. Furthermore, the rubber plate is in close contact with the ring, which strengthens the isolation between the charging interface and the outside. This solves the problem that in the existing lithium-to-dry battery assembly shell, when the charging interface is not in use, dust, moisture and other impurities can easily enter the interior of the charging interface, causing corrosion and damage to the charging interface, resulting in poor contact and affecting the normal charging of the lithium-to-dry battery.

[0017] 2. When assembling this utility model, place the lithium battery into the mounting cavity, then push the conical elastic ring on the ring downwards through the rounded edge of the outer shell until the conical elastic ring and the outer wall of the outer shell are completely in contact. Then place the circuit board inside the ring and let the charging interface engage inside the notch, pressing the circuit board and compressing the spring. The outer wall of the circuit board is fixedly connected to the ring with silicone. When it is necessary to replace the lithium battery or repair the circuit board, the ring can be pulled out from the top of the outer shell, improving the disassembly and assembly efficiency of the device.

[0018] 3. By coating the surface of the circuit board with conformal coating, the waterproof performance of the circuit board is improved, and the silicone sealant ensures the sealing of the mounting cavity. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 This utility model provides an embodiment of a 1.5V lithium-to-dry battery assembly housing, comprising a housing 1 and a ring 2. The ring 2 is movably fitted onto the outer ring of the top of the housing 1. A notch is fixedly opened on the side of the ring 2, and a charging interface 4 is placed inside the notch. A voltage reduction component is arranged inside the ring 2, which includes a circuit board 3. The circuit board 3 is fixedly arranged on the inner wall of the top of the housing 1. The charging interface 4 is fixedly arranged on one side of the bottom of the circuit board 3. The positive electrode 15 of the dry battery is arranged in the middle of the top of the circuit board 3, and a circuit element 16 is arranged on the other side of the bottom of the circuit board 3. An installation cavity is arranged inside the housing 1 for placing a lithium battery 14. A spring is arranged between the top of the lithium battery 14 and the circuit board 3. The upper end of the spring is fixedly connected to the circuit board 3, and the lower end of the spring is movably attached to the lithium battery 14. The voltage of the lithium battery 14 is converted to 1.5V by the circuit board 3 before being output. The circuit and control of the circuit board 3 and the lithium battery 14 in this utility model are existing technologies and will not be described in detail here.

[0028] When assembling this utility model, the lithium battery 14 is placed inside the mounting cavity. Due to the rounded corners of the top edge of the outer shell 1, and the bottom of the ring 2 being provided with a conical elastic ring, the conical elastic ring and the outer shell 1 are interference-fitted. The conical elastic ring on the ring 2 is pushed down through the rounded edge of the outer shell 1 until the conical elastic ring and the outer side wall of the outer shell 1 are completely fitted together, and the ring 2 can no longer be pressed down. Then, the circuit board 3 is placed inside the ring 2, and the charging interface 4 is engaged inside the notch, pressing the circuit board 3, so that the spring is compressed. The outer side wall of the circuit board 3 is fixedly connected to the ring 2 through silicone. This completes the assembly of the outer shell, improving the assembly efficiency of this utility model.

[0029] The surface of circuit board 3 is coated with conformal coating to improve its waterproof performance, and the silicone sealant ensures the sealing of the mounting cavity.

[0030] When it is necessary to replace the lithium battery 14 or repair the circuit board 3, simply pull the ring 2 out from the top of the outer casing 1 to improve the efficiency of disassembly and assembly of the device.

[0031] Considering that when the charging interface 4 is not in use, dust, moisture and other impurities can easily enter the interior of the charging interface 4, causing corrosion and damage, resulting in poor contact and affecting the normal charging of the lithium-to-dry battery, this utility model provides a protective component on the outer ring of the circular ring 2. The protective component includes a fixing ring 5, which is fixedly set on the outer ring of the circular ring 2. A sliding groove 6 is fixedly opened inside the fixing ring 5, which penetrates the upper surface of the fixing ring 5. A slider 7 is movably set inside the sliding groove 6. A movable plate 8 is fixedly set on the top of the slider 7. A rubber plate 9 is fixedly set on the side of the movable plate 8 near the circular ring 2. The rubber plate 9 is movably attached to the outer wall of the circular ring 2, and the lower surface of the rubber plate 9 is movably attached to the upper surface of the fixing ring 5. The height of the upper surface of the rubber plate 9 is the same as the height of the upper surface of the circular ring 2.

[0032] Specifically, when the charging port 4 is not in use, pushing the movable plate 8 causes the slider 7 to slide inside the groove 6, which in turn causes the rubber plate 9 to move on the outer wall of the ring 2. This allows the rubber plate 9 to cover the charging port 4, preventing dust, moisture, and other impurities from entering the interior of the charging port 4. Furthermore, the rubber plate 9 fits closely to the ring 2, enhancing the isolation between the charging port 4 and the outside. This solves the problem in existing lithium-to-dry battery assembly casings where, during use, dust, moisture, and other impurities easily enter the interior of the charging port 4 when it is not in use, causing corrosion and damage, resulting in poor contact and affecting the normal charging of the lithium-to-dry battery.

[0033] When you need to use charging port 4, simply reverse the process to open charging port 4.

[0034] Furthermore, a heat dissipation cavity 10 is fixedly provided in the middle of the rubber plate 9. When the charging interface 4 has just finished using it and the temperature is still high, the heat dissipation cavity 10 facilitates the heat dissipation of the charging interface 4. Since the heat dissipation cavity 10 is a thermally conductive material, the heat is dissipated outward through the heat dissipation cavity 10.

[0035] Furthermore, a first anti-slip texture 11 is fixedly provided on the side of the movable plate 8 away from the rubber plate 9, and a second magnetic plate 13 is fixedly provided on both sides of the movable plate 8. Two first magnetic plates 12 are fixedly provided on the outer wall of the ring 2. The two first magnetic plates 12 are respectively located on both sides of the slide groove 6. The first anti-slip texture 11 facilitates the displacement of the movable plate 8, and the first magnetic plates 12 and the second magnetic plates 13 facilitate the fixation of the position of the movable plate 8.

[0036] Furthermore, a second anti-slip texture 17 is fixedly provided on the outer ring of the fixing ring 5. By setting the second anti-slip texture 17, the friction between the hand and the ring 2 can be increased when the conical elastic ring is pulled out, thereby making it easier to pull the ring 2 out of the outer shell 1.

[0037] Working principle: When assembling this utility model, the lithium battery 14 is placed inside the mounting cavity, and the conical elastic ring on the ring 2 is pushed down through the rounded edge of the outer shell 1 until the conical elastic ring and the outer wall of the outer shell 1 are completely in contact. Then, the circuit board 3 is placed inside the ring 2, and the charging interface 4 is engaged inside the notch, pressing the circuit board 3 and compressing the spring. The outer wall of the circuit board 3 is fixedly connected to the ring 2 by silicone. This completes the assembly of the outer shell. When the charging interface 4 is not in use, the movable plate 8 is pushed, which causes the slider 7 to slide inside the slide groove 6, thereby causing the rubber plate 9 to move on the outer wall of the ring 2. The rubber plate 9 covers the charging interface 4, preventing dust, moisture and other impurities from entering the interior of the charging interface 4. Furthermore, the rubber plate 9 is closely attached to the ring 2, strengthening the isolation between the charging interface 4 and the outside.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
