DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The following descriptions are exemplary embodiments only, and are not intended to limit the scope, applicability or configuration of the invention in any way. Rather, the following description provides a convenient illustration for implementing exemplary embodiments of the invention. Various changes to the described embodiments may be made in the function and arrangement of the elements described without departing from the scope of the invention as set forth in the appended claims.
Referring to FIG. 1-4, which are respectively an exploded view, a cross-sectional view, and partial perspective views of a preferred embodiment according to the present invention, these drawings clearly show that the present invention provides a quick assembling/disassembling structure for motor handle module of electrical gear box, which comprises the following components.
A firearm body 1 is provided with a trigger 11. The firearm body 1 has an end forming a coupling section 12 to be coupled with a grip 2 that will be further described. The coupling section 12 has inside surfaces forming a guide section 13. The guide section 13 is composed of a raised portion and a recessed portion.
The grip 2 is coupled, in a sideways manner, to the firearm body 1. The grip 2 forms a connection slot 21 and a connection section 22 that is coupled to the coupling section 12.
A snap-fitting element 3 is rotatably mounted to the firearm body 1 and is set at a location adjacent one side of the trigger 11 and has an end forming a snap-fitting section 31 that is in retaining engagement with the connection slot 21.
The coupling section 12 has outside surfaces forming at least one slide groove 14 to slidably receive the connection section 22 therein. The coupling section 12 is provided with at least one connector 15 and the connector 15 is located at one side of the guide section 13. The snap-fitting element 3 forms, at a location remote from the snap-fitting section 31, a joint section 32 that is connectable to the firearm body 1. The grip 2 receives therein a motor 25 that is provided with bevel gear 24 and comprises an elastic member 23. The motor 25 is provided with a connector support 26. The firearm body 1 receives therein a disk gear 16 mating the bevel gear 24.
With the above structure and arrangement, the operation of the present invention will be described as follows with reference to FIGS. 2-6, which are respectively a cross-sectional view, partial perspective views, and operation illustrating views, these drawings show that the present invention generally comprises a firearm body 1 that comprises a trigger 11 and a grip 2 that is sideways coupled to the firearm body 1. When a user intends to remove the grip 2, the joint section 32 of the snap-fitting element 3 that is connected to the firearm body 1 is forcibly pulled downward, whereby through a see-saw action, the snap-fitting section 31 formed at the opposite end of the snap-fitting element 3 is moved upward away from the connection slot 21 of the grip and the grip 2 is allowed to slide off the slide groove 14. During the disassembling process, since the disk gear 16 of the firearm body 1 and the bevel gear 24 of the grip 2 are in mated engagement with each other, so that during the operation of sliding off, the raised and recessed arrangement of the guide section 13 is used to force the grip 2, after separating from the firearm body 1, to move in a predetermined direction in order to reduce interference between the disk gear 16 and the bevel gear 24. On the other hand, when the user wishes to re-assemble the grip 2 to the firearm body 1, the grip 2 is positioned to align with the slide groove 14 formed in the firearm body 1 for sideways insertion to couple the grip 2 with the firearm body 1. During such a process, to prevent the motor 25 received in the grip 2 and the bevel gear 24 mounted to the motor 25 from engaging the disk gear 16 of the firearm body 1 in such a direct manner as to cause damage, the guide section 13 that is formed in inside surfaces of the coupling section 12 of the firearm body 1 is used to guide the grip 2, during the insertion process, to move along a predetermined path (namely being guided along the raised and recessed arrangement of the guide section 13) to complete coupling. During the process of coupling, the elastic member 23 that is provided for the motor 25 in the connection section 22 of the grip 2 provides a function of cushioning so as to suppress noise generated during the operation of the motor 25. After the above process is completed, the connection slot 21 of the grip 2 is set in engagement with the snap-fitting section 31 of the snap-fitting element 3 again, so that the connector 15 is connected to the motor 25 of the grip 2 to achieve the purpose of quick assembling and disassembling. Further, the connection of power supply for the motor 25 is also a novel technical feature of the present invention. The conventional way of power supply for a motor is done by electrical wire connecting to a battery and a switch. The wire lay-out and maintenance are troublesome. In the present invention, the quick assembling/disassembling structure for motor handle module comprises a connector 15 arranged at each of two opposite inner sides of the coupling section 12 of the gear box and connected by electrical wire to a power distribution board. A connector support 26 is arranged behind the bevel gear 24 of the motor 25 of the connection section 22 of the grip 2 and the connector support 26 has two ends each provided with a connector 15 connected by an electrical wire to a power terminal under the motor 25. When the grip 2 is sideways coupled to or separated from the firearm body 1, the connectors 15 arranged at inner sides of the coupling section 12 of the gear box are connected to or disconnected from the connectors on the connector support 26 behind the bevel gear 24 of the motor 25 to achieve the purposes of easy replacement of components.
However, it is noted that what described above is illustration of a preferred embodiment and is not intended to impose undue limitation to the scope of the present invention. All simple modifications or equivalent structures of what described and taught in the specification and drawings are considered belonging to the scope of the appended claims.
Thus, referring to all the drawings, when compared to the known techniques, the present invention provides the following advantages in use.
The combined operation of the snap-fitting element 3 and the guide section 13 allows a user to easily replace components so as to achieve quick replacement operation of the grip 2.
It will be understood that each of the elements described above, or two or more together may also find a useful application in other types of methods differing from the type described above.
While certain novel features of this invention have been shown and described and are pointed out in the annexed claim, it is not intended to be limited to the details above, since it will be understood that various omissions, modifications, substitutions and changes in the forms and details of the device illustrated and in its operation can be made by those skilled in the art without departing in any way from the spirit of the present invention.
