Battery-and-charger assembling structure for a handheld power tool

Abstract

A battery-and-charger assembling structure includes a battery and a charger. The battery is detachably mounted on the handheld seat or in the charger. The battery has two first grooves formed on two side surfaces. Each first groove has a transverse segment and a longitudinal segment connected to each other vertically or substantially vertically. The handheld seat has two first assembling segments. The charger has two first charger assembling segments. The first assembling segments or the first charger assembling segments are selectively mounted in the two transverse segments respectively. Each of the first assembling segments or each of the first charger assembling segments engages with or disengages from the corresponding first groove, thereby strengthening the connection between the battery with the handheld seat or the charger.

What is claimed is: 
     
         1 . A battery-and-charger assembling structure for a handheld power tool comprising:
 a charger having
 a battery groove formed on a top surface of the charger; and 
 two first charger assembling segments formed on two side walls of the battery groove toward each other; and 
   a battery detachably mounted on the charger and having
 a casing having
 a connecting surface mounted in and connected to the battery groove of the charger; and 
 two first grooves formed on two side surfaces of the casing respectively; each of the first grooves having
 a transverse segment extending toward a front end of the casing and a rear end of the casing; a front end of the transverse segment being closed; and 
 a longitudinal segment extending toward a top end of the casing and a bottom end of the casing; the longitudinal segment connected to and communicating with a rear end of the transverse segment, extending to the connecting surface of the casing, and forming a first opening on the connecting surface of the casing; the two first charger assembling segments of the charger selectively mounted in the two transverse segments of the two first grooves of the casing respectively; each of the first charger assembling segments entering or departing from the corresponding first groove through the corresponding first opening. 
 
 
   
     
     
         2 . The battery-and-charger assembling structure as claimed in  claim 1 , wherein
 the transverse segment of each of the first grooves of the casing is located adjacent to the connecting surface; and   the longitudinal segment of each of the first grooves of the casing is located adjacent to a middle between the front end of the casing and the rear end of the casing.   
     
     
         3 . The battery-and-charger assembling structure as claimed in  claim 1 , wherein
 the casing of the battery further has
 two second grooves respectively formed on two side surfaces of the casing, located in the back of the two first grooves, and spaced apart from the two first grooves; each of the second grooves extending toward the front end of the casing, extending to a rear surface of the casing, and forming a second opening on the rear surface of the casing; and 
   the charger further has
 two second charger assembling segments respectively formed on the two side walls of the battery groove toward each other, located in the back of the two first charger assembling segments, and spaced apart from the two first charger assembling segments; the two second charger assembling segments selectively mounted in the two second grooves of the casing respectively; each of the second charger assembling segments entering or departing from the corresponding second groove through the corresponding second opening; 
   when each of the first charger assembling segments of the charger enters the corresponding first groove through the corresponding first opening, each of the second charger assembling segments is aligned to the second opening of the corresponding second groove;   when each of the first charger assembling segments is moved into the transverse segment of the first groove, each of the second charger assembling segments is moved into the second groove.   
     
     
         4 . The battery-and-charger assembling structure as claimed in  claim 2 , wherein
 the casing of the battery further has
 two second grooves respectively formed on two side surfaces of the casing, located in the back of the two first grooves, and spaced apart from the two first grooves; each of the second grooves extending toward the front end of the casing, extending to a rear surface of the casing, and forming a second opening on the rear surface of the casing; and 
   the charger further has
 two second charger assembling segments respectively formed on the two side walls of the battery groove toward each other, located in the back of the two first charger assembling segments, and spaced apart from the two first charger assembling segments; the two second charger assembling segments selectively mounted in the two second grooves of the casing respectively; each of the second charger assembling segments entering or departing from the corresponding second groove through the corresponding second opening; 
   when each of the first charger assembling segments of the charger enters the corresponding first groove through the corresponding first opening, each of the second charger assembling segments is aligned to the second opening of the corresponding second groove;   when each of the first charger assembling segments is moved into the transverse segment of the first groove, each of the second charger assembling segments is moved into the second groove.   
     
     
         5 . The battery-and-charger assembling structure as claimed in  claim 1 , wherein the battery groove of the charger further has
 a front end configured to accommodate the front end of the transverse segment of the battery; and   a rear end configured to accommodate the rear end of the transverse segment of the battery; a height above ground level of the rear end of the charger is lower than a height above ground level of the front end of the charger so that the battery inclines when the battery is mounted on the charger.   
     
     
         6 . The battery-and-charger assembling structure as claimed in  claim 4 , wherein the battery groove of the charger further has
 a front end configured to accommodate the front end of the transverse segment of the battery; and   a rear end configured to accommodate the rear end of the transverse segment of the battery; a height above ground level of the rear end of the charger is lower than a height above ground level of the front end of the charger so that the battery inclines when the battery is mounted on the charger.
