[0020] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0021] like Figure 1 and Figure 2As shown, a flashlight battery safety structure includes a body 11, a head 12, and a cap 13. The two ends of the body 11 are respectively connected to the head 12 and the cap 13. The head 12 and the body 11 are fixedly connected. The head 12 is a lamp assembly. The cap 13 and the body 11 are detachably connected. A slot is provided on the circumference of the body 11. The body 11 and the cap 13 are engaged through the slot. A button 14 is provided on one end of the cap 13. The button 14 is a flashlight switch.

[0022] The flashlight has a through-hole battery compartment 21 inside the body 11. The battery compartment 21 has a positive contact 22, which is located at the end of the battery compartment 21 near the head 12 and is connected to the head 12. The cover 13 has a negative contact 15. When a battery is installed in the battery compartment 21, the cover 13 seals the battery compartment 21, and the positive contact 22 and the negative contact 15 come into contact with the positive and negative terminals of the battery, thereby providing power to the flashlight.

[0023] like Figure 3 As shown, a retaining ring 24 is connected to the positive contact 22. A connecting groove 23 is provided at the center of the positive contact 22. The retaining groove 24 is located in the connecting groove 23. One end of the retaining ring 24 is fixedly connected to the connecting groove 23, and the other end of the retaining ring 24 extends out of the connecting groove 23 and can contact the battery.

[0024] The flashlight also includes a lithium battery 31 and a battery holder, which is used to install other batteries. The lithium battery 31 and the battery holder operate within the battery compartment 21.

[0025] Both the lithium battery 31 and the battery holder are fixedly connected to an electrical contact 34. The electrical contact 34 is an additional protrusion that abuts against the retaining spring 24. The electrical contact 34 can contact the positive contact 22 through the retaining spring 24. The electrical contact 34 can also pass through the retaining spring 24 and be embedded in the connecting groove 23, which can ensure the connection stability between the battery and the contact.

[0026] The lithium battery 31 can be used normally in the battery compartment 21, while the battery rack is used to assemble other types of batteries, so that batteries with different signals can work in the same way as the lithium battery 31.

[0027] like Figure 4 As shown, the battery rack includes a first battery rack 32 and a second battery rack 33. The first battery rack 32 is used to install 3AAA batteries, while the second battery rack 33 is used to install 18650 batteries.

[0028] Among them, such as Figure 5As shown, the first battery holder 32 includes a housing 324, and an inner cavity 321 is provided inside the housing 324. The inner cavity 321 is used to hold 3AAA dry batteries. The inner cavity 321 is divided into three parts, and each of the three parts of the inner cavity 321 has an opening 323 for installing and removing the batteries. At the same time, the inner cavity 321 has a contact spring 322 at the bottom of the three parts. The dry batteries are secured in the inner cavity 321 by the contact spring 322.

[0029] A control module 325 is fixedly connected to one end of the outer casing 324. The control module 325 is a simple control circuit. When the flashlight is being charged, the control module 325 restricts the charging of the dry cell battery. The 3AAA battery in the first battery holder 32 can only be discharged.

[0030] The control module 325 and the power contact 34 are fixedly connected, and the other end of the housing 324 is provided with a contact. When the first battery rack 32 is installed in the battery compartment 21, the contact on the housing 324 and the negative contact 15 on the cylinder cover 13 are in contact, and the battery rack 32 can work normally.

[0031] And such Figure 6 As shown, the second battery holder 33 includes a protective sleeve 332 and a protective cover 333. The protective sleeve 332 and the protective cover 333 are threaded together. The inner side of the protective sleeve 332 and the protective cover 333 has a cavity to accommodate the 18650 battery cell. A power contact 34 is fixedly connected to the protective cover 333. The power contact 34 passes through the protective cover 333 and contacts the 18650 battery cell. The bottom of the protective sleeve 332 is provided with a contact hole 331. When the second battery holder 33 is installed in the battery compartment 21, the negative contact 15 can pass through the contact hole 331 and contact the 18650 battery cell, thereby realizing the power supply of the flashlight.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
