Embodiment approach 1

[0039] Implementation mode one: if Figure 1-5 As shown, the car rechargeable LED torch includes a casing composed of a barrel body 1 and a lamp cap 2. A rechargeable battery 3 is provided inside the barrel body 1, a car cigarette lighter plug is provided at the rear, and the lamp cap 2 is connected at the front. The battery 3 is connected to form a lighting circuit, the car cigarette lighter plug is connected to the rechargeable battery 3 to form a charging circuit, and the cylinder body 1 and the lamp cap 2 can be rotated relative to each other. Parts of the lighting circuit and the charging circuit are arranged in the lamp cap 2, and pass through the lamp cap 2 respectively. Two pairs of sliding contacts are connected with corresponding parts arranged in the cylinder body 1, and the lighting circuit and the charging circuit are conducted at different indexing positions.

[0040] The sliding contact on the cylinder body 1 is an elastic contact, and the contact on the lamp ca...

Embodiment approach 2

[0043] Implementation mode two: if Figure 6-10Shown: the total number of the elastic contacts is three (A, B, C), the rear end of the rechargeable battery 3 and the central joint 5 of the automobile cigarette lighter plug are jointly connected with the elastic contacts (A), and the elastic contacts (B ) is connected to the front end of the rechargeable battery 3, and the elastic contact (C) is connected to the outer joint of the automobile cigarette lighter plug—the metal ring 4; the total number of the contact pieces is four (a, b, c, d), and two of them The pieces (a, b) are connected to the discharge circuit, corresponding to the elastic contacts (A, B), and the remaining two contacts (c, d) are connected to the charging circuit, corresponding to the elastic contacts (C, A). Wherein the contact pieces (a, d) are all on the rotation track of the elastic contact point (A), and the elastic contact point (C) and the contact piece (c) are respectively on the axis of the cylinde...

Embodiment approach 3

[0044] Implementation mode three: if Figure 11-20 As shown, two opposite arc-shaped grooves 6 are provided on the inner side of the front end of the cylinder body 1, and two opposite protrusions 7 are arranged on the lamp cap 2, and the protrusions 7 are snapped into the arc-shaped grooves 6, and the two arc-shaped grooves 6 The end is provided with a positioning protrusion 8, and the protruding block 7 is provided with a corresponding positioning depression 9.

[0045] The lamp head is provided with an optical alignment mirror 10 , the white light LED is arranged at the center of the optical alignment mirror 10 , and the red light LED is arranged at an eccentric position of the optical alignment mirror 10 . The remaining components and structures are as described in Embodiment 1.

[0046] Compared with the second embodiment, the contact piece (d) is not fan-shaped, and only when the charging circuit is turned on, the elastic contact (B) and the contact piece (b) are in cont...

Abstract

The invention relates a rechargeable flashlight, especially to a vehicular rechargeable LED flashlight capable of being charged by the vehicular cigar lighter socket. The current vehicular LED illuminators have big volume, inconvenient portability, and unattractive appearance. For solving the technical problems above, the flashlight comprises a housing composed of a flashlight body and a head, with storage batteries inside, provided with a vehicular cigar lighter plug in the rear, and connected to the head in the front, an illuminating circuit formed by LEDs and the storage batteries, a charging circuit formed by connected the vehicular cigar lighter plug and the storage batteries, wherein the flashlight body and the head can be rotated relatively, the illuminating circuit, charging circuit is arranged in the head partially, connected to the relative parts in the flashlight body through 2 pairs of sliding contacts, and conducted in the different rotation positions. The invention has the advantages of ultra-small size, convenient use, high brightness and indicative charging, suitable for most vehicles with cigar lighter socket.

Description

technical field [0001] The invention relates to a rechargeable torch, in particular to a car rechargeable LED torch which can be charged by a car cigarette lighter socket. Background technique [0002] The Chinese invention patent authorized by the announcement on March 21, 2007, with the announcement number CN2881346Y, discloses a kind of LED lighting lamp for vehicles, which can utilize the cigarette lighter socket of the automobile to provide power. However, this kind of LED lighting lamp for vehicles is bulky and inconvenient to carry. When the power is supplied through the cigarette lighter socket, it needs to be connected with wires, which is inconvenient and unattractive. [0003] Somebody abroad installs rechargeable batteries and LEDs in the car cigarette lighter plug to make a car rechargeable LED flashlight that can be charged by the car cigarette lighter socket. But the volume is still relatively large, and when it is inserted into the car cigarette lighter sock...
