The handheld flashlight comprises a hollow cylinder having a first end and a second end, wherein the hollow cylinder is configured to receive therein and mount thereon a rechargeable battery; a lamp head, connected the first end of the hollow cylinder and comprising a light source; a window breaker, configured to break windows for emergency vehicular escape; a charging-discharging port, selectively connected to an external power source or an external load; a connection port, selectively connected to positive and negative terminals of a vehicle battery through external cables; and a management circuit, selectively applying power from the rechargeable battery to the light source, the charging-discharging port, and the connection, and selectively charging the rechargeable battery from the external power source through the charging-discharging port; wherein the handheld flashlight is of such compact size and low weight as to be suitable for single-handed portable operation by a user.
  • DESCRIPTION OF FIGURES
  • FIG. 1 is an explored drawing of the flashlight in the subject matter.
  • In the FIGURE, all parts numbered are as follows: 1—cylinder; 2—mounting cap; 3—lamp base; 4—punch; 5—acrylic translucent lens; 6—lithium battery; 7—management circuit board; 8—metallic case; 9—button; 10—silicone sealing cap; 11—raised edge; 12—rope; 13—light-collecting cup; 14—circuit board.
  • DETAILED DESCRIPTION
  • Features and advantages of the general inventive concepts will become apparent from the following detailed description made with reference to the accompanying drawings.
  • As shown in FIG. 1, the emergency vehicle start power supply device comprises a hollow cylinder 1, a mounting cap 2 sealed at the bottom of the cylinder 1, and a lamp head connected to the top of the cylinder 1. A light source is provided at a position inside the lamp head. The light source contains a super bright LED light for illumination, a signal light for SOS signals, and a flashing light for quick flashing. The lamp head comprises a metallic lamp base 3. One end of the lamp base 3 is in thread connection with the top end of the cylinder 1; while the other end of the lamp base 3 is open ended and is in thread connection with a metallic punch 4. A light-collecting cup 13 and an acrylic translucent lens 5 are positioned in sequence between the lamp base 3 and the metallic punch 4. The light-collecting cup 13 collects, concentrates, and redirects the light emitted from the light source. Alternatively, one end of the lamp base 3 may be in thread connection with a metallic case 8 instead of being in thread connection with the top end of the cylinder 1. The light-collecting cup 13 is made with metal and its surface is plated with silver. The metallic punch 4 is made by using metal-cutting technology. The open end of the lamp base 3 is installed with an acrylic translucent lens 5 for resisting dust and water. After positioning the metallic silver plated light-collecting cup 13 in the lamp base 3, the punch 4 is connected with the light-collecting cup 13, resulting in a set of lamp head system. The advantageous features of the lamp head system are as follows: the light-collecting cup 13 collects and concentrates light, in the meanwhile, introduces the heat from the light source to the lamp base 3, and emits the heat. The punch 4 is also made from metal and connected with the lamp base 3. They work together to dissipate heat, which can effectively improve safety and reliability.
  • The cylinder 1 is a cylindrical shell formed by fitting two pieces of half cylindrical plastic bases together. A lithium battery 6 and a management circuit board 7 are installed inside the cylinder 1. The lithium battery 6 provides electricity for the light source through the management circuit board 7. The cylinder 1 is sleeved by a metallic case 8 in a way in which the cylinder has an interference fit with the metallic case. As an example, the cylinder 1 is tightly surrounded by the metallic case 8 and is coupled to the metallic case 8 such as through a groove on the cylinder receiving a projection on the metallic case 8. A button 9 is provided on the cylinder 1 wall to control the illumination, and delivers help signals or quick flashing through the management circuit board 7. The button 9 extends upward through the metallic case 8. A rope 12 is attached to the bottom of the cylinder 1, which makes the utility model easy to be carried. In the case of emergency when driving, the LED light can be turned on for illumination through the button 9. the SOS signal light and quick flashing light can be turned on through button 9 in case that people cannot move. Through achieving the emergency illumination and signaling signal for help and quick flashing, rescue teams can find trapped people as quickly as possible. Button 9 is located on the cylinder and close to the lamp head, which meets the requirements of ergonomics and facilitates manual control.
  • A circuit board 14 is installed inside the cylinder 1. A charging-discharging port and a connection port are provided on the mounting cap 2. There may be more than one ports or interfaces (such as USB interface), so as to obtain more functions, such as for charging more devices. The charging-discharging port can be used for charging and discharging purpose. For example, the lithium battery 6 outputs the electricity power, successfully via the circuit board 14 and charging-discharging port. The lithium battery provides electricity power successfully through the circuit board 14, and connection ports, which are connected to the positive and negative terminals of a vehicle battery or the connectors of the positive and negative terminals of a vehicle battery. A silicone sealing cap 10 is provided on the mounting cap 2 for sealing the charging-discharging port and the connection port. It is important for some time that a communication device can be kept in a normal communication. The communication device can be charged through the charging-discharging port so as to be kept in a normal communication with the outside world. When travelling in the wild, if the vehicle's engine is damaged, its battery is empty, and the vehicle cannot be started, the lithium battery can function as a small power supply source to charge the vehicle battery and start the vehicle, through connecting the connection port to the positive and negative terminals of the vehicle battery. As the vehicle carries with itself a lithium battery as an assistant power source, the vehicle can still drive for several miles to reach a service area or garage for repairing.
  • The power supply device is designed as being completely enclosed by metal in the external. The metal concerned contains the punch 4, the lamp base 3 and the metallic case 8, which are abutted and fixed with screw threads. The metallic case 8 and the cylinder 1 work together to strengthen the abutting with the lamp base 3. The lithium battery 6 and the circuit boards (the management circuit board 7 and the circuit board 10) are fixed inside through the plastic cylinder 1 and the mounting cap 2. The silicone sealing cap 10 seals the bottom of the cylinder, resisting dust and water.
  • In view of the many possible embodiments to which the principles of the disclosed invention can be applied, it should be recognized that the illustrated embodiments are only preferred examples of the invention and should not be taken as limiting the scope of the invention. All combinations or subcombinations of features of the foregoing exemplary embodiments are contemplated by this application. The scope of the invention is defined by the following claims. We therefore claim as our invention all that comes within the scope and spirit of these claims.
