It is a cross-sectional view showing.

As shown in the drawings, the auxiliary battery device 30 according to an embodiment of the present invention includes a case body 31, an upper cover 39 and a connecting line (3) containing a secondary battery 32 such as a battery or a rechargeable battery ( 65 is connected to the case body 31 and includes a plug portion 71 for electrical connection with the player body.

The inner bottom of the auxiliary battery built-in case body 31 is provided with a compression coil spring 33 that is typically used as a negative electrode terminal. The compression coil spring 33 serves to push up the auxiliary battery 32 when the upper cover 39 is opened. In the drawings, a compression coil spring is used as a negative electrode terminal, but a compression leaf spring may be used instead.

The case body 31 may be formed by dividing the inner cylinder and the outer cylinder or may be formed as a single cylinder. In FIG. 2 and FIG. 3, the inner and outer cylinders are divided, and FIG. 4 is illustrated as a single cylinder for the sake of simplicity. As will be described later, it is preferable to use a case body divided into an inner cylinder and an outer cylinder in order to connect the conducting wire coming out from the positive electrode terminal to the connecting line 65.

As clearly shown in FIG. 4, first and second protrusions 37 and 55 protruding from the case body 31 in the vertical direction of the case body are formed to face each other. The first and second protrusions 37 and 55 may be formed in two parallel plate shapes and the two parallel plates may be horizontally connected to each other at a lower portion thereof. In addition, holes 37 and 57 are formed in the plates of the first and second protrusions 37 and 55, respectively.

The auxiliary battery built-in case upper cover 39 includes a side portion 41 coupled to the first protrusion 37 and an upper portion 49 covering the auxiliary battery built-in case body 31. In the side portion 41 of the upper cover 39, a hole 43 corresponding to the hole 37 of the first protrusion 37 is formed. Accordingly, the side portion 41 and the first protrusion 37 of the upper cover are coupled by two pins 45 connected by the spring 47. As such, the upper cover 49 coupled to the first protrusion 37 by pin coupling becomes a structure capable of rotating about the coupled pin 45 as an axis. Although the shape of the pin is simply represented in FIG. 4, it is very easy for a person having ordinary skill in the art to design a pin in a shape suitable for joining, and thus a detailed description of the pin will be omitted. Shall be.

The upper 49 of the upper cover 39 has a positive electrode terminal 50 formed on an inner surface thereof to be connected to the positive electrode of the built-in auxiliary battery. The positive electrode terminal 50 is connected to the connecting line 65 along the extended lead. The conductive wires extending from the positive electrode terminal 50 may be formed in any shape. In the auxiliary battery device of the present invention, the upper cover 39 has a structure in which the pin 45 can be pivoted about its axis. In contact with the inner cylinder of the case body 31 with the side 41 of the upper cover closed, for example, an extended conductor is formed along the inner cylinder surface of the side 41 of the upper cover and the case body 31. Can be connected to the connecting line 65.

On the other hand, by forming the insulator protrusion rib ribs 53 on the upper cover 39, the negative electrode of the auxiliary battery does not come into contact with the positive electrode terminal when the auxiliary battery is reversely inserted. The reverse voltage can be prevented from forming.

Moreover, the hook 51 is provided in the upper part 49 of the position which opposes the side part 41 of the upper cover 39 downward. The bent direction of the hooks 51 provided is outside of the case.

The push knob portion is coupled to the second protrusion 55 by a pin 63. The push knob portion extends upward from the push knob 59 and the push knob 59, which are touched by the user. 60 and a torsion coil spring 61. The hook 60 of the push knob portion is engaged with the hook 51 of the upper cover and is bent inward to correspond to the bending direction of the hook 51 of the upper cover. The torsion coil spring 61 is mounted inside the push knob part by the ring of the coil being fitted to the pin. In the mounted state, one end is supported by the case body and the other end is supported by the push knob 59.

As shown in FIG. 2, the auxiliary battery device 30 of the present invention having such a structure serves as a door for accommodating the auxiliary battery in the case body, and the hook of the upper cover (when the upper cover is closed). 51) and the hook 60 of the push knob portion is fitted. This hook engagement can be maintained by the effect of the force acting in the outward direction by the elasticity of the torsion coil spring 61 of the push knob portion pushes the hook 60 of the push knob portion inward. If the torsion coil spring 61 is not present, when the auxiliary battery device is inclined in the direction of the second protrusion 55, the hook coupling may be dismantled. Next, in order to replace the hook-up battery and to open the top cover by disassembling the hook as described above, the user simply touches the push knob 59 with a finger. Then, as shown in Figure 3, the push knob 59 enters inward while the hook 60 of the push knob part is opened outwards, and the hook coupling is disassembled. As the hook coupling is dismantled, the auxiliary battery 32 and the upper cover 39 freed from the hook coupling are forced upward by the elasticity of the compression coil spring 33 installed on the inner bottom of the case body 31. 39 is opened and the auxiliary battery 32 is slightly raised. At this time, the torsion coil spring 61 of the push knob portion exerts an elastic force on the push knob 59 in the outward direction in the open state, but the force causes a physical change, that is, the push knob portion is in the closed position. It is better to choose the spring's elasticity so that it doesn't get enough. That is, the torsion coil spring 61 functions to keep the push knob portion in the current state, that is, the position of the open state or the closed state, by appropriate selection of its elasticity. If there is no torsion coil spring 61 in the open state, the auxiliary battery device is inclined in the direction of the first protrusion 37 so that the position of the push knob becomes a closed position, which makes it inconvenient to close the upper cover, that is, the door.

In order to close the upper cover 39 in the open state, the upper cover 39 is simply rotated and pressed downward. Then, as the hook 51 of the upper cover 39 presses down the inner portion of the push knob portion below the hook 60 of the push knob portion, this force and the elastic force of the torsion coil spring 61 are combined to push the push knob portion. Hook 60 is moved inward to form a hook coupling.

Therefore, the auxiliary battery device of the present invention can open and close the upper cover by a simple operation, that is, by pressing the push knob to open the upper cover (door) and pressing the upper cover downward to close the upper cover.

In addition, as an important feature of the present invention, the auxiliary battery device 30 according to an embodiment of the present invention may have a connection plug 67 for electrical connection with the player body. The connection plug 67 is connected to the (+) electrode terminal 50 and the (-) electrode terminal 33 by a connection line 65 provided at the lower portion of the case body 31. The connection plug 67 is coupled to a corresponding connector formed in the player body, and is a connection means for transmitting the power of the auxiliary battery to the player body. The connecting means consisting of only one connecting plug 67 is an element which makes it easy to be separated from the main body by causing the auxiliary battery device to rotate about it. Therefore, the support plug 69 is integrally installed by the plug integrating means 71 together with the connection plug 67 in order to prevent rotation and detachment of the auxiliary battery device. The plug integrating means 71 is a means for integrally moving the support plug 69 and the connecting plug 67, and can be formed in the same way as the means for integrating two headphone or earphone jacks.

As described above, unlike the conventional auxiliary battery device that forms an electrical connection while maintaining a mechanical coupling with the side of the player body, the auxiliary battery device of the present invention is connected with a connection plug that can be mechanically coupled with the electrical connection at the same time. By using a support plug capable of supporting the engagement of the plug, it is possible not only to form a firm coupling with the player body but also to engage the player body of various shapes.
