Abstract

A car jump start power source comprises a casing assembly having an accommodating chamber as well as a press key, an optical condenser, a light guide bar, an electrical device assembly and a battery pack provided in the accommodating chamber; the casing assembly comprising a top casing, a bottom casing, a rubber cover covering a three-hole socket, a top aluminum casing and a bottom aluminum casing; and the top casing being mounted on the bottom casing in a non-detachable manner, and the accommodating chamber being collectively surround by the top casing and the bottom casing. One first mounting hole is provided in a top of the bottom casing, and the rubber cover is mounted at the first mounting hole. A separation plate is provided on the bottom casing, and the separation plate separates the accommodating chamber into a front chamber in which the press key, the optical condenser, the light guide bar and the electrical device assembly are mounted and a rear chamber in which the battery pack is mounted. Power from the battery pack is led out via a three-hole socket to an electric accumulator of a motorcar through an intelligent cable for a jump start.

Claims

1. A car jump start power source, characterized in that it comprises a casing assembly having an accommodating chamber as well as a press key, an optical condenser, a light guide bar, an electrical device assembly and a battery pack provided in the accommodating chamber, the casing assembly comprising a top casing, a bottom casing, a rubber cover, a top aluminum casing and a bottom aluminum casing, the top casing being mounted on the bottom casing in a non-detachable manner, and the accommodating chamber being collectively surrounded by the top casing and the bottom casing;

wherein one first mounting hole is provided in a top of the bottom casing, and the rubber cover is mounted at the first mounting hole, and

wherein a separation plate is provided on the bottom casing, and the separation plate separates the accommodating chamber into a front chamber in which the press key, the optical condenser, the light guide bar and the electrical device assembly are mounted and a rear chamber in which the battery pack is mounted.

2. The car jump start power source of claim 1, wherein the casing assembly comprises a top casing assembly and a bottom casing assembly, the top casing assembly having the top aluminum casing, a double-sided adhesive sheet, the top casing and the light guide bar;

wherein the top aluminum casing is bonded and fixed to the top casing via the double-sided adhesive sheet;

wherein the light guide bar is composed of four light guide columns arranged in a row and connected integrally and provided with a mounting piece configured to fix the light guide bar, four light guide bar mounting holes are provided in the mounting piece, and light guide bar fixing posts configured to mate with the light guide bar mounting holes are provided in the front chamber of the top casing; and

wherein four light guide bar mounting holes are opened in the top casing, one end of the light guide bar protrudes out of the light guide bar mounting holes of the top casing, and the light guide bar is fixedly mounted in the top casing via the light guide bar fixing posts.

3. The car jump start power source of claim 1, wherein the casing assembly comprises a top casing assembly and a bottom casing assembly, the bottom casing assembly having the bottom aluminum casing, a double-sided adhesive sheet, the bottom casing, the press key and the rubber cover;

wherein the bottom aluminum casing is bonded and fixed to the bottom casing via the double-sided adhesive sheet;

wherein an elastic hook tab for fixation is provided on the press key;

wherein a fixing hook configured to mate with a mounting hole of the press key is provided in the front chamber of the bottom casing, and the press key is fixedly mounted in the bottom casing by the fixing hook; and

wherein an elongate back catch for fixation is provided on the rubber cover, and an oblong hole configured to mate with the rubber cover is provided in the front chamber of the bottom casing.

4. The car jump start power source of claim 1, wherein the electrical device assembly comprises a circuit board as well as a USB port, a power switch, a spotlight and an LED indicator fixed to the circuit board;

wherein the circuit board, the USB port, the power switch, the spotlight and the LED indicator are mounted in the front chamber; and

wherein a USB port mounting hole located at a position corresponding to the USB port and an optical condenser mounting hole located at a position corresponding to the spotlight are opened in an end face of the front chamber of the bottom casing.

5. The car jump start power source of claim 4, wherein the optical condenser is provided between the spotlight and the optical condenser mounting hole.

6. The car jump start power source of claim 1, wherein convex ribs are provided on both end edges of the top casing, and concave slots configured to mate with the convex ribs of the top casing are provided on both end edges of the bottom casing;

and wherein rabbet convex ribs are provided on both side edges of the bottom casing, and concave slots configured to mate with the rabbet convex ribs of the bottom casing are provided on both side edges of the top casing.

7. The car jump start power source of claim 1, wherein at least four projections are provided on each of both side edges of the bottom casing, and recesses configured to mate with the projections are provided on both side edges of the top casing.
