## Background
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to a car flashlight structure, and more particularly to a flashlight that is able to provide car interior illumination, and that facilitates using a car charger to replenish electric power. Moreover, a unique assembly of the flashlight effectively minimizes the physical size, thereby reducing the space occupied by the flashlight and facilitating storing away when not in use.
(b) Description of the Prior Art
Modern people attach great importance to the quality of life, thus, when choosing a car, buying a car or purchasing car accessories, apart from the requirements for operability and comfort, importance has also began to be attached to car interior accessories that function together. However, when driving or riding in a car at night, because of the surrounding darkness, if the driver or passenger needs to carry out some task in the car, for instance, look for an article, adjust the interior air conditioning or car stereo, change a music disc or even take some food, an auxiliary light source is usually required to illuminate the car interior to assist in carrying out the task.
The absence of an auxiliary light source is currently resolved by fitting an overhead night light in the roof of the car interior. However, the overhead night light is of a fixed type that only projects light downwards, thereby leaving many dead angles where the light does not illuminate. Moreover, if the user wants to conduct tasks outside the car where there is no lighting, the user is unable to use the overhead night light in the car interior for auxiliary illumination. Hence, some people may carry a flashlight when traveling in a car, which can be used for auxiliary illumination when inside the car or when outside the car in unlit surroundings. However, auxiliary illumination provided by a conventional flashlight relies on ancillary batteries. If battery power is exhausted when using the flashlight, then electric power required by the flashlight cannot be replenished.
Currently, a car, cigarette lighter connector can be bought for use as a charger to charge a car flashlight. However, the conventional car flashlight is oversized, and the majority of conventional car cigarette lighter connectors are fitted at a side of the gear lever, which takes up space when charging the flashlight, and hinders driving the car, thus increasing the risk of a car accident.
In light of the aforementioned shortcomings of the conventional car flashlight during practical usage, having accumulated years of experience in related arts, attentively and circumspectly carried out extensive study and exploration to ultimately design a new structure for a car flashlight.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIGS. 1, 2 and 3, which show the present invention structured to comprise a cylindrical body 1, a cap 2, a casing cover 3, an illumination assembly 4 and an outer cylinder 5.
Referring to FIGS. 2, 3 and 4, the cylindrical body 1 comprises a first casing 11 reciprocally combined with a corresponding second casing 12. At least one first slide track 111 is defined on a surface of the first casing 11, and at least one second slide track 121 is defined on a surface of the second casing 12. Moreover, a set of positioning grooves 122 are respectively defined on two ends within the second slide track 121, and a through hole 112 is defined at an appropriate position in the first casing 11. Furthermore, a protruding catch 113 is configured on a surface of a rear end of the first casing 11 of the cylindrical body 1.
Referring to FIGS. 2, 3, 7, 8, 9, 10, 14 and 15, the cap 2 is disposed on a front end of the aforementioned cylindrical body 1. The cap is provided with a sleeve 21, and a transparent cover 22 provided with a convex lens seals a front end thereof. First slide strips 23 corresponding to the aforementioned first slide tracks 111 and second slide strips 24 corresponding to the aforementioned second slide track 121 extend from a rear end of the sleeve 21. The slide strips 23, 24 enable the cap 2 to slide along the lengths of the first slide tracks 111 and the second slide track 121 of the cylindrical body 1 respectively. Moreover, two sets of flanges 241 are respectively configured on two ends of the second slide strips 24 of the cap 2 so as to correspond to the positioning grooves 122, and a rear end of the sleeve 21 forms an acting face 25.
Referring to FIGS. 2, 3, 4, 5, 6 and 13, an end of the casing cover 3 is provided with a holding cavity 31, which provides for socket joining the rear ends of the aforementioned first casing 11 and second casing 12 of the cap 2 therein. A curved slide groove 311 is defined within the holding cavity 31 of the casing cover 3 so as to correspond to the protruding catch 113. Thus, after socket joining the first casing 11 and the second casing 12 of the cylindrical body 1 within the holding cavity 31 of the casing cover 3, the protruding catch 113 is securely positioned within the curved slide groove 311, thereby positionally retaining the casing cover 3. Furthermore, another end of the casing cover 3 is provided with a storage groove 32, center of which is defined a through hole 33. Two ends of the through hole 33 penetrate the holding cavity 31 and the storage groove 32 respectively. A contact bar 34 is disposed in the through hole 33, penetrates through the holding cavity 31, and protrudes from the storage groove 32. Moreover, an elastic electrically conducting contact member 341 extends from a front end of the contact bar 34, which is used to make an electrical contact with a first contact point 61 within a charger 6. Furthermore, a strong magnetic ring 35 is disposed within the storage groove 32.
Referring to FIGS. 2, 3, 4, 5, 6, 13, 14 and 15, the illumination assembly 4 is configured between the first casing 11 and the second casing 12 within the aforementioned cylindrical body 1. The illumination assembly 4 is provided with at least a base plate 41, on top of which is configured at least one accumulator unit 42, and at least one LED light 43. Furthermore, an electrical conducting contact portion 44 extends from a rear end of the base plate 41, and makes an electrical connection with the elastic electrical conducting contact member 341. Moreover, a second electrical conducting contact portion 45 extends from a side of the base plate 41, and penetrates the through hole 112 of the first casing 11. The second electrical conducting contact portion 45 is used to make an electrical contact with a second contact point 62 within the charger 6. A contact switch 46 is further configured on the base plate 41 so as to correspond to the aforementioned acting face 25. The contact switch 46 is provided with a rear end first contact piece 461 and a front end second contact piece 462, wherein the first contact piece 461, is disposed at a side of the acting face 25 of the cap 2. When the cap 2 is moved forward, the first contact piece 461 is made to come in contact with the second contact piece 462, thereby forming an electrical connection with the illumination assembly 4.
Referring to FIGS. 1, 4, 6, 11, 12 and 12A, the outer cylinder 5 is made from conductor material, and is disposed on an outer end of the cylindrical body 1, thereby covering the first casing 11 and the second casing 12, and enabling the second electrical conducting contact portion 45 to make an electrical connection with the outer cylinder 5. Moreover, elastic pieces 51 are respectively configured on two sides of the outer cylinder 5, which are used to make electrical contact with the second contact point 62 within the charger 6.
Referring to FIGS. 1, 2, 3, 4, 6, 7, 8, 9, 10, 14, 15, 16 and 17, the aforementioned structure can be plugged into the charger 6 as generally provided as a car interior accessory. Because aperture diameter of the charger 6 is not necessarily the same in all cars, If the aperture diameter of the charger 6 is relatively large, then the elastic pieces 51 on the outer cylinder 5 and the contact bar 34 of the cover 3 can be used to make contact with the second contact point 62 and the first contact point 61 within the charger 6 respectively, thereby charging the accumulator unit 42 within the illumination assembly 4. When electric power in the accumulator unit 42 is replenished, the user can take out the flashlight from the charger 6 and directly push the cap, 2 forward, thereby causing the cap 2 to slide along the first slide tracks 111 of the first casing 11 and the second slide track 121 of the second casing 12 of the cylindrical body 1, which actuates the acting face 25 at the rear end of the sleeve 21 of the cap 2, and causes the first contact piece 461 of the contact switch 46 to make electrical contact with the second contact piece 462, thereby providing an electric current to the LED light of the illumination assembly 43, which thus projects light out from the transparent cover 22 at the front end of the cap 2 that provides the user with auxiliary illumination. Whereas, when the cap 2 is pushed back to its original position, the first contact piece 461 is made to separate from the second contact piece 462, which causes the LED light to extinguish. Moreover, sliding distance of the cap 2 can be adjusted to vary the distance between the LED light 43 and the transparent cover 22, thereby adjusting focus of the light source and illumination range of the light beam. When the cap 2 is adjusted to an appropriate distance, then the flanges 241 of the second slide strips 24 are clasped within the positioning grooves 122, thereby securely positioning the cap 2. When the user is looking for an article or carrying out some task inside a car, then the strong magnetic ring 35 at the end of the cover 3 can be used to magnetically attract and secure the flashlight to an appropriate position in the car interior, thereby freeing both hands of the user to carry out tasks without the need to divide his attention to handling the flashlight.
According to the aforementioned embodiment, the present invention can be seen to have the following advantages:
1. The car flashlight, configured from the cylindrical body 1 structured by reciprocally combining the first casing 11 and the corresponding second casing 12, and the cap 2 joined therein, provides an effective compact flashlight that does not take up space when not in use.
2. The car flashlight can conveniently use the charger 6 in a car to replenish electric power, thereby achieving the need for convenience of use.
3. The strong magnetic ring 35 at the end of the cover 3 of the car flashlight can be used to magnetically attract and secure the flashlight to any position in the car interior, thereby providing the user with a fixed auxiliary light source that frees both hands to carry out tasks.
In conclusion, the aforementioned detailed disclosures of the structural art of the present invention clearly show that the present invention achieves the objectives of convenience and safety when driving.
