FIG. 4 b shows a perspective view of the cover 170 with the coupling unit 180. The cover 170 completely surrounds the energy supply unit 160 in a closed state. In this embodiment, the lid 170 encloses the handheld power tool battery pack 164 and protects it from environmental influences. The lid 170 forms a hollow volume 172. The handheld power tool battery pack 164 can essentially be arranged completely in the hollow volume 172, see also FIGS. 2 and 3. Here, the coupling unit 180 has, in addition to the locking device 188 with the locking element 189, at least one spring element 181, at least one closing element 182, at least one stop element 185, at least one guide element 186 and at least one sealing element 187. In this embodiment form two spring elements 181 are provided, wherein the two spring elements 181 are formed as two coil springs. In addition, two closing elements 182 are each formed with a coupling element 184, wherein the two closing elements 182 are formed as two closing slides 183. The two spring elements 181 act on the two closing elements 182. The coupling element 184 is designed as a coupling pin. Next four stop elements 185 are formed, which are formed out as four stop webs. The four stop elements 185 are provided to provide at least one on impact for the spring elements 181 and the closing elements 182. In addition, the four stop elements 185 receive the guide element 186. The guide element 186 is formed as a guide rod. The guide element 186 guides the two closing elements 182. The sealing element 187 seals the lid 170 with respect to the housing 110. Here, the sealing element 187 is formed as a sealing ring.

In Fig. 5 are two perspective views of two embodiments of the protective device 200 is shown. The frame 210 comprises at least one receiving element 230. Here, four receiving elements 230 are formed, wherein the four Aufnahmeele elements are formed as four notches 232. The four receiving elements 230 receive the housing 110 at least partially positively. This will then become a Four point storage of the housing 110 in the frame 210 allows. Preferably, the frame 210 forms the four receiving elements 230 such that they are integral with the frame 210. FIG. 5a shows a perspective view of the protective device 200 in a first embodiment

Embodiment in which the frame 210 is integrally formed. FIG. 5b illustrates a front view of the protection device 210 in a second embodiment in which the frame 210 is two-piece. Here, the frame 210 at least one connec tion element 240. The connecting element 240 connects a first part 242 of the frame 210 to a second part 244 of the frame 210 and forms a positive and non-positive connection from the first part 242 to the second part 244. Here four connecting elements 240 are formed. Two Verbindungsele elements 240 are formed as a plug-in element 246, wherein the plug-in elements 246 are formed as a plug. Two connecting elements 240 are formed as coupling elements 248, wherein the coupling elements 248 are formed out as a coupling receptacles. The two plug-in element 246 are in the two coupling element 248 plug bar, so then the first part 242 is connected to the second part 244.
