[0017] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of the present application is:

[0019] See also Figure 1-3 , Figure 1 This is a schematic diagram of the overall structure of a metal shell of a handheld instrument battery with a heat dissipation structure according to the first embodiment of the utility model. Figure 2It is a structural schematic diagram of the radiator of the first embodiment of the utility model. Figure 3 It is a structural schematic diagram of a battery housing according to the first embodiment of the utility model.

[0020] The utility model provides a handheld instrument battery metal shell with a heat dissipation structure: comprising a battery shell 101, a mounting plate 102 and a spring 103, and also comprising a heat dissipation device, wherein the heat dissipation device comprises a top plate 105 and a radiator 106, wherein the radiator 106 comprises a fixing plate 107 and a fin 108, wherein the fin 108 is further provided with an arc groove 109, and the battery shell 101 is further provided with a drainage groove 110. The above-mentioned scheme solves the above-mentioned problem that a large amount of heat is released during charging and discharging of the battery, and the heat dissipation performance of the conventional battery shell is poor, which causes the accumulation of heat inside the battery, thereby affecting the service life of the battery. It can be understood that the present scheme can also be used to solve the problem of improving the stability of battery installation.

[0021] In this embodiment, through the cooperation of the top plate 105 and the radiator 106, the heat generated by the battery during the charging and discharging process can be quickly discharged, thereby avoiding the accumulation of battery heat and thus improving the service life of the battery.

[0022] The top plate 105 is fixedly mounted on the battery housing 101 and is located in the groove 104. The radiator 106 is mounted on the battery housing 101 and is located on the side of the battery housing 101 close to the top plate 105. The battery housing 101 is U-shaped. The number of the mounting sheet 102 and the spring 103 are three groups, respectively, and are close to the three groups of grooves 104. The mounting sheet 102 is a metal sheet. The spring 103 is welded on the mounting sheet 102. The number of the top plate 105 is three groups, and they are respectively located in the three groups of grooves 104. The cross-section of the top plate 105 is rectangular. The heat sink 106 is distributed between every two groups of the grooves 104. When in use, the batteries are placed above the top plate 105 in the grooves 104 respectively. At the same time, the ends of the batteries are abutted against the springs 103 to fix the batteries. The top plate 105 lifts the batteries so that the bottom of the batteries is an overhead structure, so that the heat generated by the batteries can circulate with the air. At the same time, the heat sink 106 can conduct the heat generated by the batteries to the air by heat conduction, so that the heat generated by the batteries during the charging and discharging process can be quickly discharged, avoiding the accumulation of heat in the batteries and thus increasing the service life of the batteries.

[0023] Secondly, the fixing plate 107 is fixedly mounted on the battery housing 101; the fins 108 are fixedly mounted on the fixing plate 107, and multiple groups of the fins 108 are linearly distributed on both sides of the fixing plate 107. The fixing plate 107 and the fins 108 are both made of aluminum, which has good thermal conductivity. Through the good heat conduction effect of the fins 108, the heat generated by the battery can be discharged.

[0024] Again, the arc groove 109 runs through the fin 108 . The arrangement of the arc groove 109 makes it easier for the fin 108 to fully contact with the battery.

[0025] Finally, the drainage groove 110 runs through the groove 104 . The drainage groove 110 is perpendicular to the groove 104 and is interconnected. Through the arrangement of the drainage groove 110 , the heat flow accumulated in the groove 104 can be discharged through the drainage groove 110 .

[0026] In this embodiment, when in use, the batteries are respectively inserted into the grooves 104 so that one end of the battery abuts against the spring 103. Since the top plate 105 is fixed in the grooves 104, the top plate 105 lifts the battery so that the bottom of the battery is suspended to facilitate air circulation. At the same time, the fins 108 on the fixing plate 107 are in contact with the battery, so that the heat generated by the battery can be guided into the air through the fins 108. At the same time, the drainage grooves 110 can guide the heat flow accumulated in the grooves 104, so that the heat generated by the battery during the charging and discharging process can be quickly discharged, avoiding the accumulation of battery heat, thereby increasing the service life of the battery.

[0027] The second embodiment of the present application is:

[0028] See also Figure 4 ,in Figure 4 It is a schematic diagram of the overall structure of a metal battery shell of a handheld instrument with a heat dissipation structure according to the second embodiment of the utility model. Based on the first embodiment, the metal battery shell of a handheld instrument with a heat dissipation structure in this embodiment further includes an insert 201 .

[0029] In this embodiment, the installation stability of the battery is improved by the cooperation between the inserting piece 201 and the wedge-shaped protrusion 203 .

[0030] Among them, a movable groove 202 is provided on the side of the battery housing 101 away from the mounting plate 102, the plug-in sheet 201 is slidably mounted on the battery housing 101 and is located in the movable groove 202, a wedge-shaped protrusion 203 is provided on the plug-in sheet 201, the number of the plug-in sheets 201 is three groups, and they are respectively close to the three groups of the grooves 104, the cross-section of the plug-in sheet 201 is L-shaped, the wedge-shaped protrusion 203 is located at the bottom of the plug-in sheet 201, and is trapezoidal. When the battery is installed in the groove 104, the plug-in sheet 201 is inserted into the groove 104, so that the wedge-shaped protrusion 203 at the bottom of the plug-in sheet 201 contacts the end of the battery, and the battery is pushed to the other side of the groove 104, so that the battery is pressed into contact with the spring 103, thereby improving the installation stability of the battery.

[0031] In this embodiment, after the battery is installed in the groove 104, the inserting piece 201 is inserted into the groove 104 so that the wedge-shaped protrusion 203 at the bottom of the inserting piece 201 contacts the end of the battery, and the battery is pushed to the other side of the groove 104 so that the battery contacts the spring 103, thereby improving the installation stability of the battery.
