Abstract

A hand-cranked charger comprising a handle, a left housing (1), a right housing (2), a top housing (3), a motor, and a circuit board. A handle placement position (14) is provided on the left housing (1). The handle is collapsibly placed on the handle placement position (14). The handle and the motor are connected therebetween via a gear set. Because the gear set is provided between the handle and the motor, and torque when rotating the handle weakens as the gear set rotates, adverse effects of torque on the motor when the handle is rotated vigorously or when the handle is just starting to be rotated are prevented, thus making the hand-cranked charger highly stable.

Description

Hand charger

[Technical Field]

The present invention relates to the field of daily necessities, and more particularly to a hand-cranked charger. 【Background technique】

I have designed a hand-cranked charger, including a handle, a left case, a right case, a top case, a motor, a circuit board, and a handle placement position on the housing, the handle being foldably placed on the handle placement position , the handle is directly connected to the motor. This program is not public. Since the handle is directly connected to the motor, the torque is large when the rotation and the turning force are large, which may cause damage to the structure inside the motor, and the stability of the hand charger is low.

[Summary of the Invention]

The technical problem to be solved by the present invention is to provide a hand-cranked charger with high stability.

Preferably, the gear set includes a handle gear, a connecting gear and a motor gear, the connecting gear meshes with the handle and the motor gear, the handle gear is connected with the handle, and the motor gear is connected with the motor.

Preferably, the handle comprises a rotating handle, a connecting shaft and a rotating handle, and the rotating handle is connected to the connecting shaft through a shaft, and the rotating handle is rotatable on the connecting shaft. By connecting the shaft, the shank can be rotated and placed in parallel on the housing.

Preferably, the rotating handle is further provided with a rotating handle fixing hole, and the rotating handle is fixed on the rotating handle by rotating the handle fixing hole. Preferably, the rotating handle is rotated by 0° to 180° with the pin connecting the rotating shaft, and the handle placing position further includes a rotating handle placing position and a rotating handle placing position. When the rotating handle rotates by 0°, the rotating position is rotated. The handle is attached to the rotating handle placement position on the left casing, and the rotating handle is placed on the rotating handle placement position.

Preferably, the turning handle is placed in a groove provided on the left casing, the depth of the groove being equal to the thickness of the rotating handle. In this way, when the rotating handle is placed in the groove, the surface of the casing is flat and convenient to carry.

Preferably, the left shell and the right shell are coupled through the top shell, and LED lights are disposed at the connection of the left and right shells, and the LED lights can be powered by the hand charger. Set the LED light, and the hand charger can also be used as a flashlight.

Preferably, the hand-cranked charger is further provided with a radio integrated circuit, and the top case is provided with a radio button for controlling the radio. A radio integrated circuit is provided, and the hand-cranked charger can also be used as a radio.

Preferably, the right shell is provided with a solar panel, and the solar panel can supply power to the hand charger. A solar panel is placed on the right casing to charge the hand charger under the influence of sunlight.

According to the invention, since the gear set is arranged between the handle and the motor, the torque when the handle is rotated is weakened by the transmission of the gear set, avoiding

Ringing, making the stability of the hand charger high

[Description of the Drawings]

Figure 1 is a schematic overall view of an embodiment of the present invention;

2 is a schematic view of a gear set of an embodiment of the present invention.

Among them: 1, the left shell; 2, the right shell; 3, the top shell; 11, the handle; 12, the connection shaft; 13, the handle; 14, the handle placement; 15, the groove; 4, LED lights; Solar panel; 111, handle gear; 112, connecting gear; 113, motor gear.

【detailed description】 The invention will now be further described with reference to the drawings and preferred embodiments.

As shown in FIG. 1 and FIG. 2, the hand charger of this embodiment includes a handle, a left case 1, a right case 2, a top case 3, a motor, a circuit board, and a handle placement position 14 is disposed on the left case 1. The handle is foldably placed on the handle placement position, and the handle is coupled to the motor through a gear set. According to the present invention, since the gear set is disposed between the handle and the motor, the torque when the handle is rotated is weakened by the transmission of the gear set.
