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.

[0021] Please see Figure 1-5 One embodiment provided by this utility model:

[0022] A 1.5V lithium-to-dry battery structure includes a battery compartment 1, a lithium battery 3, and a DC-DC step-down chip 44. A metal cover 11 is fixedly connected to the surface of the battery compartment 1. A base plate 12 is threadedly connected to the end of the battery compartment 1 away from the metal cover 11. A limiting member 2 is slidably connected inside the battery compartment 1. A support plate 21 is fixedly connected to the surface of the limiting member 2. A placement plate 22 is fixedly connected to the surface of the support plate 21. A fixing plate 23 is fixedly connected to the surface of the placement plate 22. A support spring 24 is fixedly connected to the surface of the fixing plate 23. A stop plate 25 is fixedly connected to the surface of the support spring 24. A connection port 31 is provided on the surface of the lithium battery 3. A step-down chamber 4 is fixedly connected to the side of the limiting member 2 away from the support plate 21. A base plate 43 is provided inside the step-down chamber 4. The surface is provided with a first contact plate 41 and a second contact plate 42. A DC-DC step-down chip 44 is electrically connected to the surface of the substrate 43. A connecting plate 5 is provided inside the battery compartment 1. A third contact plate 51 is provided at one end of the connecting plate 5. A contact rod 52 is elastically slidably connected to the other end of the connecting plate 5. Through the sliding connection between the battery compartment 1 and the limiting member 2, and with the connection between the support plate 21 and the placement plate 22, the position of the lithium battery 3 in the battery compartment 1 is limited. Through the action of the DC-DC step-down chip 44, the voltage of the lithium battery 3 is reduced. The DC-DC step-down chip 44 is an existing product, and its principle is existing technology, which will not be described in detail here. Under the action of the second contact plate 42 and the contact rod 52, the lithium battery 3 completes the voltage reduction operation.

[0023] Furthermore, the limiting member 2 is plate-shaped and slides against the inner wall of the battery compartment 1. The support plate 21 is evenly distributed in four groups on the surface of the limiting member 2. The placement plate 22 and the support plate 21 are connected accordingly. Through the sliding connection between the limiting member 2 and the battery compartment 1, the installation position of the lithium battery 3 in the battery compartment 1 is limited by the connection between the support plate 21 and the limiting member 2.

[0024] Furthermore, the fixing plate 23 is plate-shaped and fixedly connected to the placement plate 22. The placement plate 22 is fixed to the surface of the support plate 21 in an inclined state. Through the connection between the placement plate 22 and the fixing plate 23, the inclined connection between the placement plate 22 and the support plate 21 achieves the support effect for the installation position of the lithium battery 3 in the battery compartment 1.

[0025] Furthermore, the abutment plate 25 is elastically connected to the placement plate 22 via the support spring 24. The surface of the abutment plate 25 abuts against the outer surface of the lithium battery 3 via the support spring 24. Through the connection of the fixing plate 23 and the support spring 24, and the connection of the support spring 24 and the abutment plate 25, the lithium battery 3 is ensured to be on the central axis of the battery compartment 1 under the abutment contact between the abutment plate 25 and the lithium battery 3, ensuring the accurate insertion of the connection port 31 and the insertion interface on the limiting member 2.

[0026] Furthermore, the surface of the limiting member 2 is provided with an insertion interface. The lithium battery 3 is connected to the insertion interface through the connection port 31. The lithium battery 3 and the substrate 43 are electrically connected through the insertion interface and the connection port 31. Through the connection of the lithium battery 3 and the connection port 31, the electrical connection between the lithium battery 3 and the substrate 43 is achieved by inserting the insertion interface on the connection port 31 and the limiting member 2.

[0027] Furthermore, both the first contact plate 41 and the second contact plate 42 are electrically connected to the substrate 43. The second contact plate 42 abuts against the inner wall of the metal cover 11, and the first contact plate 41 abuts against the third contact plate 51. Through the abutting contact of the first contact plate 41 and the third contact plate 51, and the abutting contact of the second contact plate 42 and the inner wall of the metal cover 11, the voltage output operation after stepping down the lithium battery 3 is realized.

[0028] Furthermore, a circuit board is provided inside the connecting plate 5. The third contact plate 51 and the contact rod 52 are electrically connected through the circuit board. A spring is provided on the surface of the contact rod 52. The contact rod 52 is in elastic contact with the inner wall of the base plate 12 through the spring. Under the electrical connection between the contact rod 52 and the third contact plate 51, the voltage output effect of the metal cover 11 and the base plate 12 is realized when in use.

[0029] Working principle: When performing voltage reduction operation on lithium battery 3, lithium battery 3 is installed on placement plate 22. With the connection between placement plate 22 and fixing plate 23, and the connection between support spring 24 and abutment plate 25, lithium battery 3 slides on the central axis of battery compartment 1, ensuring that connection port 31 and insertion interface on limiter 2 are accurately inserted. Under the action of substrate 43 and DC-DC step-down chip 44, the voltage reduction operation of lithium battery 3 is completed. With the abutting contact of first contact plate 41 and third contact plate 51, the abutting contact of second contact plate 42 and metal cover 11, the electrical connection of third contact plate 51 and contact rod 52, and the abutting contact of contact rod 52 and base plate 12, the voltage reduction effect of lithium battery 3 is achieved.
