Description

Charging device

Technical Field

The utility model relates to a charger, especially, be a charger of flashlight.

Background

U.S. patent application No. 2006181865 discloses the construction of a flashlight. The flashlight is powered by conventional batteries mounted within the three support rods of the flashlight. When the electric energy of the battery is exhausted, the battery needs to be taken out, and the battery is placed into a common charger to be fully charged and then is placed into the supporting rod, so that the flashlight can work again. Such operation steps are relatively many and the operation is also relatively troublesome. And the flashlight cannot be used while the battery is charging.

In order to solve the above problems, a rechargeable battery is first used to provide electric energy to the flashlight without taking out the battery, and a novel charger is also needed to enable the flashlight to be used while charging. However, since the flashlight is elongated in shape, when inserted into a conventional charger, the flashlight may tip over with the charger due to the center of gravity being too high. Because of the above problems, the charger of the present invention is improved to some extent. Such safety problems are not limited to flashlights, and all elongated objects to be charged have the problem that they may tilt together with the charger due to the high center of gravity during charging.

In addition, most of the chargers currently sold on the market can only be placed on the ground or on a table to charge the object to be charged, but when the ground is level or uneven, which causes charging errors, it is necessary to provide a charger capable of charging the object without being placed on the ground or on the table.

Detailed Description

As shown in fig. 1, the utility model discloses a charger, including a body 1 to and set up in body 1, can be to the charging circuit 2 (shown in fig. 2) that is charged by the thing that charges, this charging circuit adopts the charging circuit of ordinary charger, just this is not adding the unnecessary redundancy. The charger body 1 comprises a top surface 3 and a bottom surface 4, a circular side surface 5 is connected between the top surface 3 and the bottom surface 4, and a part of the side surface 5 is a plane part 51 in the embodiment. The top surface 3 is provided with a charging indicator lamp 31 for indicating that the charger is in the process of charging or charging is completed.

On the side 5 of the charger, as in the prior art, there is a power cord 8 and a plug 9 for the ac current. The utility model discloses a place that the thing was placed to the charger is different with prior art, is a through-hole 6 that extends to bottom surface 4 from top surface 3, and the thing that is charged can be placed in through-hole 6 to reduce the height by the thing that charges, make its focus can be located the inside of charger. The top surface 3 and the bottom surface 4 of the charger are arranged at an angle, so that objects to be charged can be more easily put into the through holes 6.

Fig. 2 to 4 illustrate two charging methods of the charger of the present invention.

The charger of the present invention is suitable for charging the elongated object to be charged, as shown in fig. 2, the object to be charged in this embodiment is a flashlight 7. The rear end of the flashlight 7 is provided with a battery pack 71 and a support rod 72, as can be seen from fig. 4, the battery pack 71 is located in the center of the lower end of the flashlight 7, and a rechargeable battery 75 is arranged in the battery pack 71 to provide electric energy for the flashlight 7; three support rods 72 are arranged around the battery pack 71, and each support rod 72 can be opened with respect to the battery pack 71. The purpose of the support bar 72 is to enable the flashlight 7 to stand upright on the ground while it is open and supported on the ground, thereby generating an upward light beam.

As shown in fig. 3, the through hole 6 includes a first receiving portion 61 and a second receiving portion 62, which are respectively matched with the outer contours of the battery pack 71 and the support rod 72. The first receiving portion 61 and the second receiving portion 62 are connected together at intervals to form a whole through hole, and the positions of the first receiving portion and the second receiving portion are staggered and distributed as the positions of the battery pack 71 and the support bar 72 when the flashlight 7 is not opened in the support bar 72. The first accommodating part 61 and the battery pack 71 are matched tightly, so that the flashlight 7 cannot shake left and right after being inserted into the through hole 6, and the flashlight 7 cannot axially rotate in the through hole 6 due to the fact that the outer contour of the battery pack 71 is in a combination of three arc shapes. As shown in fig. 2, the first receiving portion 61 of the through hole 6 is further provided with a step 63. When the battery pack 71 is inserted into the through hole 6, the end 73 of the battery pack can abut against the step 63, so that the flashlight 7 is fixed with the axial position of the through hole 6 after being inserted into the through hole 6.

As shown in fig. 3, two contact holes 74 are formed in the battery pack 71, and when current flows through the contact holes 74 to form a loop, the current can charge three groups of batteries 75 in the battery pack 71. In order to charge the battery 75, the charging contact 64 is provided on the first receiving portion 61 of the charger through-hole 6, and a spring 65 is provided therein so that the charging contact 64 always has an inward tendency. The charging contact 64 is electrically connected with the charging circuit 2, and when the battery pack 71 is inserted into the through hole 6, the charging contact 64 can extend into the contact hole 74 of the battery pack under the action of the spring 65, so as to charge the battery 75.

As shown in fig. 2 and 3, the charger of the present invention is in the first charging mode. The support bar 72 of the flashlight 7 is now not open and abuts against the battery pack 71. When the flashlight needs to be recharged, the battery pack 71 is inserted into the through hole 6 along with the support rod 72. Since the support rod 72 and the battery pack 71 of the flashlight 7 are elongated and the support rod 72 is slightly longer than the battery pack 71, when the two are inserted into the through hole 6, the flashlight 7 needs to be extended into the charger as far as possible in order to locate the center of gravity of the flashlight inside the charger. At this time, the end of the support rod 72 extends from the bottom surface 4 of the charger body 1, so that the bottom surface 4 of the charger body 1 cannot be laid on the ground. In view of this, the present embodiment is provided with a hook 52 that can suspend the charger from a wall or a round hole 53 into which a pin can be inserted, on a plane portion 51 of the side face 5 of the charger. When a projection, such as a screw, is inserted into the circular hole 53 of the charger on the wall, the charger and the flashlight can be hung on the wall for charging. Similarly, the hook 52 serves this purpose to allow the charger to be suspended in a supported position. This charging mode is mainly suitable for the situation that the charger can not be placed on the ground. Because the utility model provides a flashlight 7 has emergency circuit, even do not plug the power to 9 of charger, and just place flashlight 7 according to first mode of charging and hang on the wall in the charger, also enable flashlight 7 and produce the function of emergency light after the outage.

As shown in fig. 4 and 5, the charger of the present invention is in the second charging mode. At this point, the three support rods 72 of the flashlight 7 are opened, and form an angle with the battery pack 71. When the flashlight needs to be charged, the battery pack 71 is inserted into the through hole 6, and the support rods 72 are diverged to be located outside the charger body 1. Since the support rod 72 of the flashlight 7 is not inserted into the through hole 6, the tip 73 of the battery pack 71 does not protrude from the bottom surface 4 of the charger body 1. And the tail end of the support rod 72 and the bottom surface 4 of the charger are positioned in the same plane, so that the charger can be placed on a horizontal ground, and the support rod 72 and the bottom surface 4 of the charger play a supporting role, so that the charger cannot incline, and is safer and more reliable.

The utility model has a plurality of specific implementation modes. All technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the scope of the present invention.
