Detailed Description
Fig. 1 and 2 show a tool battery 10a of a system with a tool battery 10a and a hand tool not shown in detail. The tool battery 10a has a coupling device 30a which is mechanically and electrically coupled to the hand tool in a functional state. The tool battery 10a also has a battery cell unit 12a, a sealing film 14a and a battery housing 26 a.
The battery cell unit 12a includes an electrical equipment receiving area 16a, a battery holder 18a, a plurality of batteries 20a, and a battery circuit 22 a. The battery holder 18a secures the battery 20a and the battery circuit 22a within the electrical equipment receiving area 16 a. The battery holder 18a furthermore defines an electrical device receiving region 16a in this direction, which is perpendicular to the mounting direction of the battery 20a in the battery holder 18 a. The battery holder 18a is formed of two parts. The battery 20a and the battery circuit 22a should be in the first portion 32a of the battery holder 18 a. The electrical device receiving area 16a of the battery holder 18a is then largely covered by the second section 34a of the battery holder 18 a. The battery holder 18a thus divides the electrical equipment housing area 16a into a plurality of areas.
The sealing film 14a completely encloses the battery cell unit 12 a. The not-shown superposition of the two regions of the sealing film 14a and the not-shown joint of the two regions of the sealing film 14a are bonded to each other. The sealing film 14a thus seals the electrical equipment housing region 16a of the battery cell unit 12a against dust and water. The battery holder 18a holds the battery 20a and the battery circuit 22a in the region protected by the sealing film 14 a. The battery cell unit 12a has a cable exit hole 36 a. A cable 38a of the tool battery 10a, which connects the battery cell unit 12a to the coupling device 30a, is led out through the cable outlet opening 36 a. The sealing film 14a is formed as a double layer. Having a soft layer formed of a polyamide of higher crack strength and a layer formed of a polyethylene of higher elasticity. The sealing film 14a is pressed against the battery cell 12a by the low pressure. This is achieved by closing the sealing membrane 14a at a pressure of less than 0.9 bar.
The battery case 26a prevents external machinery from affecting the battery cell unit 12a and the sealing film 14 a. The battery case 26a is formed of thermoplastic. Which surrounds the battery cell unit 12a and the sealing film 14 a. The battery case 26a has a plurality of ventilation holes 28a through which air can flow around the sealing film 14 a. The battery case 26a can thereby discharge the moisture that has entered from the battery case 26 a. Even if the battery case 26a is mechanically damaged, moisture does not enter the battery case 26a, but does not leak out.
Three further embodiments of the invention are shown in figures 3 to 6. The following description and the drawing description are primarily limited to the differences between the exemplary embodiments, wherein the reference numerals of the components having the same reference numerals, in particular with reference to components having the same reference numerals, can be substantially referred to the drawing description and/or the description of the further exemplary embodiments, in particular fig. 1 and 2.
The reference numerals of the embodiment of fig. 1 and 2 are adjusted backwards in order to distinguish the embodiment letter a. The letter a is replaced by letters b to d in the embodiments of figures 3 to 6.
Fig. 2 and 4 show a tool battery 10b with a battery cell unit 12b, a sealing film 14b and a battery housing 26 b. The battery cell unit 12b includes a battery holder 18b and a plurality of batteries 20 b. The sealing film 14b seals the electrical equipment housing region 16b of the battery cell unit 12b against dust and water. The battery holder 18b holds the battery 20b in the electrical equipment housing area 16 b. The battery 20b is inserted into the battery holder 18 b. The battery holder 18b has two open sides 24b, which are perpendicular to the insertion direction. The batteries 20b are conductively connected to each other on the open side. The sealing film 14b is joined together by fusion to the cell holder 18 b. And sealing film 14b is connected to region 40b adjacent to open side 24 b. The regions 40b each enclose one of the open sides 24 b. The sealing foil 14b thus seals the open side 24b of the battery holder 18b in a dust-tight and water-tight manner.
Fig. 5 shows a tool battery 10c having a battery cell unit 12c, a sealing film 14c and a battery housing 26 c. The battery cell unit 12c includes a battery holder 18c and a plurality of batteries 20 c. The battery holder 18c holds the battery 20c in the electrical equipment housing area 16 c. The battery 20c is inserted into the battery holder 18 c. The battery housing 26c has a first housing portion 42c and a second housing portion 44 c. The housing portions 42c, 44c are connected to one another in a usable condition in an assembly method. The coupling means 30c of the tool battery 10c is arranged on the first housing part 42 c. The coupling device 30c is sealed in a material-fusing manner.
The sealing film 14c seals the electrical equipment housing region 16c of the battery cell unit 12c against dust and water. The first housing part 42c and the sealing film 14c are joined together by material fusion. The battery cell unit 12c is enclosed in a pouch formed by a sealing film 14c when mounted. The sealing film 14c is then bonded to the first housing part 42c and in the region 46c, it adjoins the region where the housing parts 42c, 44c impact one another in a usable state. To this end, the battery holder 18c presses the sealing film 14c against the housing part 42 c. The sealing film 14c then clings to the battery cell 12c during the shrinking process. To this end, the sealing film 14c fixes the battery cell 12c to the battery housing 26 c. In a usable state, the electrical equipment accommodation area 16c is filled with an overpressure, which prevents moisture and dust from entering the electrical equipment accommodation area. An overpressure is generated when the sealing film 14c is arranged by the volume change of the region enclosed by the sealing film 14 c.
Fig. 6 shows a tool battery 10d having a battery cell unit 12d, a sealing film 14d and a battery housing 26 d. The battery cell unit 12d includes a battery holder 18d, a plurality of batteries 20d, and an energy transfer coil 48 d. The battery holder 18d holds the battery 20 d. The battery 20d is inserted into the battery holder 18 d. The energy transfer coil 48d inductively transfers energy during charging and during operation of the hand tool. The sealing film 14d seals the electrical equipment housing region 16d of the battery cell unit 12d against dust and water. The sealing film 14d is formed in three layers. The sealing film 14d, which is not shown in detail here, is formed by a water-vapor-permeable membrane and two textile layers. The textile layer is glued on both sides to the water vapour permeable membrane. The textile layer thus protects the water vapour permeable membrane from mechanical damage. The sealing film 14d completely encloses the battery cell unit 12 d. The sealing film 14d has no cable exit hole. The coupling means 30d of the battery housing 26d is only mechanically coupled to the hand tool.
Fig. 7 and 8 show a tool battery 10e with a battery cell unit 12e, a sealing film 14e, a battery housing 26e and a coupling device 30 e. The battery cell unit 12e includes one battery holder 18e, four batteries 20e, and one battery circuit 22 e. The battery holder 18e secures the battery 20e of the battery cell unit 12e in the electrical equipment housing area 16 e. The battery holder 18e includes a first battery holder portion 52e and a second battery holder portion 54e formed separately from the first battery holder 52 e. The two battery holder portions 52e, 54e define the electrical equipment accommodation region 16e on two sides opposite to each other. The first battery clamp portion 52e is formed integrally with the first housing portion 42e of the battery housing 26 e. The first battery clamp portion 52e secures the battery circuit 22 e. The battery circuit 22e is cleaved into the void of the first battery clamp portion 52 e. The coupling means 30e of the tool battery 10e is arranged on the first housing part 42 e. The second battery clamp portion 54e is formed substantially plate-like.
The sealing film 14e seals the electrical equipment housing region 16e of the battery cell unit 12e against dust and water. To this end, the sealing film 14e defines the electrical equipment housing area 16 on four sides, which do not define the battery holder portions 52e, 54 e. The sealing film 14e defines an electrical equipment housing area on this side, which is perpendicular to the side defining the first battery holder portion 52 e. The first battery clamp portion 52e has a membrane securing edge 56 e. The membrane securing edge 56e is part of the slot. The membrane securing edge 56e surrounds the first battery clamp portion 52 e. The second battery clamp portion 54e also has a membrane securing edge 58 e. The film fixing edge 58e of the second battery holder portion 54e is plate-shaped. The edges of the sealing film 14e each surround one of the film securing edges 56e, 58e during the shrinking process. The sealing film 14e thus connects the first cell holder portion 52e and the second cell holder portion 54e to each other.
