The switch circuit board 17 and the switch key 18 are provided with switch support blocks 9 for connecting the switch support blocks 9 in the circular recesses provided by the switch keys 18. An end of the circuit board support 26 facing the battery case is provided with an annular bottom cover conductive member 25 which is capable of communicating the wiring of the switch assembly 15. A conductive member 6 is also disposed at one end of the battery case adjacent to the switch assembly, which communicates with the circuitry within the battery case 2. The switch assembly 15 is electrically connected to the conductive member of the battery case 2 by a spring provided thereon, and the spring can make the switch assembly and the battery case more in contact and provide a conductive function. The user can control the switch of the LED light of the flashlight through the action opening key 18. The switch assembly 15 is disposed at an end of the housing 1 away from the lens cover 7 to facilitate the user to operate the opening key 18, and can also be used to fix the position of the battery case 2 in the flashlight housing 1 and to simplify the layout of the parts in the housing. It can be said that it is more than one thing.

The battery case 2 is housed in the cavity of the housing 1, and the bottom cover 16 of the switch assembly 15 is screwed to the housing 1. Then the position of the battery case 2 is fixed. Due to the expansion and contraction of the spring 4, the battery case 2 can be in full contact with the conductive contacts 5 and the switch assembly 15, ensuring a sufficient electrical connection between the components. Since the through hole of the fixing frame 3 can be designed with the aperture and the length as needed, and the length and diameter of the fixing frame 3 and the mounting position in the middle of the flashlight can have a certain design freedom, so that the spring 4 selected by the flashlight can be selected to be larger. The amount of expansion and contraction further enables the battery case 2 to be more fully contacted with the switch assembly 15, and on the other hand, the manufacturing accuracy requirements of the components such as the battery case, the switch assembly, and the like are reduced, thereby reducing the cost. The arrangement of the conductive contacts 5, that is, the position of the spring can be fixed, and the conductive member 6 of the battery case has excellent electric power. Connection effect. The spring 4 and the conductive contact 5 are disposed in the through hole of the fixing frame 3, thereby avoiding excessive contact between the conductive spring 4 and the conductive contact 5 and the outside, so that the corrosion effect of the two is reduced, and the two are improved. The service life of the person is very important for the conductive parts. The conductive contact of this embodiment has a cylindrical structure, and may of course be replaced by other solutions, such as a contact form or a small piece designed in the form of a sheet.

A rubber ring 27 may be disposed outside the casing 1 for anti-slip.

The flashlight can be charged to the battery of the battery case 2 through the charging stand 20, as shown in FIG. 1 and FIG.

Inside the charging stand 20, a second induction coil 21 is disposed along the charging hole 24, and a plug 22 is provided at one end of the charging stand 20, and the second induction coil 21 is electrically connected through a charging circuit board 23 provided in the charging stand 20. When the flashlight is inserted into the charging hole of the charging stand 20, when the first induction coil is opposite to the second induction coil, the charging stand 20 can chuck and fix the position of the flashlight, because the first induction coil is disposed in the middle of the casing 1, that is, The locking position of the flashlight and the charging base is in the middle of the casing, the weight distribution of the flashlight relative to the charging seat is relatively uniform, and the clamping has a fixed position, so that the position of the plug 22 of the charging stand 20 after insertion into the socket is not restricted, the flashlight The housing can be fixed to the charging stand 20. That is, the plug 22 can be inserted into the wall socket, so that the flashlight can be vertically placed and charged, or can be inserted into the flat socket, the flashlight can be placed horizontally, or the plug 22 can be inserted into the socket of another position without affecting the charging of the flashlight. At this time, the position of the second induction coil 21 and the first induction coil 8 are opposite to each other, so that after the charging stand is energized, the second induction coil and the first induction coil generate electromagnetic force, and the battery of the battery case 2 is wirelessly charged. Moreover, when carrying, the flashlight can be directly carried into the charging stand and then carried together, which is convenient for the user to carry. It should be noted that the middle portion of the present embodiment does not specifically refer to the middle position of the casing 1, but refers to the main body portion of the casing, that is, the non-end portions, including the middle portion and the middle portion of the casing 1.

Of course, the flashlight of the present invention also adopts other solutions. For example, the casing of the flashlight of the preferred embodiment is cylindrical, and may also be a cylindrical structure with a square, a polygonal cross section, etc., and a non-column structure, such as a football. Shaped. It is also possible to arrange the switch assembly in the middle of the housing or elsewhere. In addition to the LED circuit board, the lighting component can also be in the form of a bulb or the like. The flashlight housing 1 and the charging stand 20 are also connected in addition to the charging stand 20 The limiter limit can be connected.

The above is a further detailed description of the present invention in connection with the specific preferred embodiments, and the specific embodiments of the present invention are not limited to the description. It will be apparent to those skilled in the art that the present invention may be made without departing from the spirit and scope of the invention.
