Description of the embodiments
Fig. 1 shows an exemplary drive unit 100 having an electric motor 120 and a gear mechanism 130 that can be driven by the electric motor. The drive unit 100 can be used, for example, as a drive device for a sun roof in a motor vehicle. The drive unit 100 here illustratively has three fastening flanges 112 for arrangement in a motor vehicle, for example. However, the drive unit 100 may also have fewer or more than three fastening flanges 112.
Preferably, a motor housing 125 is assigned to the electric motor 120 and, for example, a gear housing 135 is assigned to the gear 130. Preferably, the motor housing 125 is fastened to the gear housing 135, for example screwed, riveted, welded, glued or fastened in any other way. Preferably, the gear mechanism 130 is designed as a worm gear, wherein a gear mechanism axis 137 assigned to the gear mechanism 130 is preferably arranged perpendicular to a motor axis 127 assigned to the electric motor 120.
It is indicated that: the configuration of the drive unit 100 with one transmission 130 has merely exemplary characteristics and should not be considered as a limitation of the present invention. Alternatively, the drive unit 100 may therefore also be designed without the transmission 130. The gear mechanism 130 or the gear mechanism axis 137 may also be arranged at any other angle relative to the motor axis 127.
According to one specific embodiment, the electric motor 120 is designed as an electronically commutated motor 120 having a motor coil 128. It is pointed out, however, that this type of electronically commutated motor is sufficiently well known from the prior art that a detailed description of the electronically commutated motor 120 is omitted here for the sake of brevity and simplicity of description.
Preferably, an electronics unit 140 is assigned to the drive unit 100, which electronics unit is preferably arranged in a housing 141. Illustratively and preferably, the housing 141 is formed integrally with the gear housing 135, but can also be connected to the gear housing 135 via any desired connection, for example via a screw connection, similar to the motor housing 125.
The electronics unit 140 is preferably assigned at least one circuit board 142, which is at least designed to make contact with the motor coil 128. The circuit board 142 is preferably oriented orthogonally to the motor axis 127 of the electronically commutated motor 120. However, the circuit board 142 can also be arranged in any other arrangement relative to the motor axis 127.
Preferably, the housing 141 has at least one (illustratively two) fixing element 152 for securely arranging the circuit board 142 in the housing 141. For contacting, the motor coil 128 preferably has at least one, preferably three, contact elements 129, which are connected to the circuit board 142 in an electrically conductive manner. Here, the preferably three contact elements 129 are arranged at least partially in the housing 141 of the electronics unit 140. For contacting, the circuit board 142 has at least one contact element 144, preferably a number of contact elements which is assigned to the number of contact elements 129, illustratively three contact elements.
According to one specific embodiment, the contact elements 144 are embodied as Surface-Mounted contact elements or SMD (Surface-Mounted Device) contact elements. In this case, the SMD connecting element 144 has at least one (illustratively two) contact section 146, 147 for connecting a contact region of the circuit board 142.
Preferably, the SMD connecting element 144 is designed as a clip connection and is electrically conductively connected to the at least one contact element 129. The SMD connecting element 144 is illustratively embodied as a double-clip terminal (Doppelklemme). The SMD connecting element 144 preferably has a U-shaped base body (Grundk) 145. However, the base 145 may have any other shape, such as a V-shape.
But it is indicated that: the embodiment of the SMD connecting element 144 as a double-clip terminal is not to be regarded as limiting the invention. The SMD connecting element 144 can therefore also be designed as a single-clip terminal (Einzelnklemme). In this case, for example, it is also possible to design one SMD connecting element 144 as a single clip terminal and the other SMD connecting element as a double clip terminal.
When mounting the circuit board 142 or during a contacting process, the SMD connecting elements 144 are first fixed on the circuit board 142. The circuit board 142 is then arranged in the housing 141, the contact of the contact element 129 with the SMD connecting element 144 being simultaneously achieved. Here, tolerances can be compensated for by the contact element 129, which is preferably made of a coated or uncoated wire. Furthermore, during assembly, a step of removing insulation is eliminated by the SMD connecting element 144, which is designed as a clip connection. Furthermore, a thermal expansion is compensated for by the contact element 129.
Fig. 2 shows the drive unit 100 of fig. 1 and illustrates the contact of the contact element 129 with the SMD connecting element 144. Here, three contact elements 129 and 252, 253, 254 are preferably visible, wherein a contact element 252 is connected to an SMD connecting element 262 and a contact element 254 is connected to an SMD connecting element 263. In this case, the contact elements 252, 253 are arranged in a positioning recess 229 assigned to the housing 141 of the electronics unit 140.
Fig. 2 also shows an SMD connecting element 144, which is preferably designed as a double-clip terminal and which is arranged on a side 203 of the circuit board 142 facing the housing 141 and has illustratively two contact sections 146, 147 thereof. As described above, the SMD connecting element 144, which is designed as a clip connection, preferably has a U-shaped base body 145, which preferably has a first and a second planar section 246, 247. The two planar sections 246, 247 are preferably arranged at least substantially parallel to one another and are connected to one another via a preferably arcuate section 245. It is pointed out, however, that the portion 245 can also have any other shape, for example an angular shape.
Preferably, the two planar sections 246, 247 each have a contact section 146, 147 at their free ends facing the side 203 of the circuit board 142 for connection to a contact region of the circuit board 142. Furthermore, the two planar portions 246, 247 form the longitudinal direction 201 of the respective SMD connecting element 144 along their longitudinal extension. The individual SMD connecting elements 144 preferably have a recess 241, which is embodied as a clip-type region, in a transverse direction 202 running transversely to the longitudinal direction 201. Such a recess 241 is preferably configured for arranging at least one of the contact elements 129 of the motor coil 128. It is pointed out that the recess 241 can also accommodate a plurality of contact elements 129 according to one embodiment.
The SMD connecting element 144 or the recess 241 is preferably designed in such a way that sufficient shock resistance is produced and an undesired loosening of the contact element 129 is prevented. In addition, a clamping force is introduced into the printed circuit board 142 during the contacting process, so that the electronically commutated motor 120 from fig. 1 is not subjected to any load during the contacting process. It is indicated that: in one embodiment of the SMD connecting element 144, the planar sections 246, 247 are designed as single-clip terminals only.
Fig. 2 also illustrates a motor shaft 212 assigned to the electronically commutated motor 120 from fig. 1, which motor shaft 212 forms the motor axis 127. The circuit board 142 is here preferably oriented orthogonally to the motor axis 127, as described above.
Fig. 3 shows the drive unit 100 of fig. 1 and 2 and illustrates a support element 305 assigned to an SMD connecting element 263 or to a contact element 254. Preferably, the housing 141 assigned to the electronics unit 140 has at least one supporting element 305, which is assigned to at least one SMD connecting element 144. The support element 305 here preferably has at least one positioning recess 229 for positioning the motor coil 128 or for positioning the contact element 129 or 254 assigned to the motor coil 128.
According to one embodiment, the support element 305 can also be designed to arrange a plurality of contact elements 129. In this case, the support element 305 can be formed integrally with the housing 141 or can be fixed to it by means of an arbitrary connection, for example an adhesive connection.
The support element 305 is preferably configured for this purpose: the contact elements 129 or 254 for contacting are positioned and/or fixed. Alternatively or optionally, the support element 305 is designed to position the SMD connecting element 144 or 263 in the housing 141.
