The auxiliary driver includes a gear device housing with an output shaft and a worm wheel and an electric motor. The electric motor is disposed within the pawl housing and includes an armature shaft, the armature shaft interacting with the worm wheel of the output shaft. The connection plug is fixed to the gear unit housing and the connection plug projects from the gear unit housing and is offset laterally with respect to the electric motor. The connection plug is used to connect the supply cable of the vehicle side and the corresponding plug of the control cable.

The gear device housing, the connecting plug connected to the housing, the pawl housing and the gear device housing cover are arranged in a fixed manner. Since several vehicle manufacturers pre-determine the different plug positions of the corresponding plugs for the vehicle electronics, the manufacturer of the auxiliary driver has to ensure that in the gear housing, the gear housing cover or the pole housing, The locations of the plugs must be specially designed, manufactured and prepared for different vehicle manufacturers. Thus, the auxiliary driver with the gear device housing must be provided with a customized plug device corresponding to each vehicle manufacturer.

It is an object of the present invention to provide an auxiliary driver including a plug device and a plug device that can have various plug positions, for example, to meet the needs of the customer.

This object is achieved by the plug device according to claim 1 and the auxiliary driver according to claim 10. The plug device according to the invention has the advantage that the plug members can be arranged in at least one housing member formed rotatably. The housing member is rotatably formed in predetermined positions, in which the plug member is disposed differently according to respective customer requirements. This allows a variety of plug devices to be obtained with one auxiliary driver, so that a separate auxiliary driver for a given plug device by the customer need not be developed and manufactured.

In the case of the preferred embodiment, one housing member is rotatably disposed within the receiving portion, or alternatively is rotatably disposed on another positioning member, e.g., one housing member. The rotatable arrangement on the other housing member has the advantage of not requiring additional receptacles. Alternatively, the receiving portion has the advantage that the housing member can be rotatably disposed even where a rotatable connection with another housing member is not possible or suitable.

In another preferred embodiment, the housing member, e.g., the pole housing, comprises at least one or more recesses. A pawl housing including a recess is rotatably disposed within a receiving portion having a corresponding protrusion that can be received in the recess. The recesses may be provided in the wall of the pawl housing. The recesses have the advantage that they can be formed particularly simply in the wall of the housing.

In another preferred embodiment of the present invention, the housing member is rotatably secured to, for example, another housing member using at least one or more hook members such as crimp hooks. The hook members of one housing member are engaged in the recesses of the other rotatably formed housing member and then bent to secure the housing member in the rotated position. This embodiment has the advantage that the two housing members can be connected to each other simply and inexpensively.

In another preferred embodiment of the present invention, the housing member is rotatably connected to, for example, another housing member using at least one or a plurality of clamping hooks. To this end, the housing member, for example the pawl housing, includes openings through which the clamping hook can be engaged. These openings can be simply implemented in a pawl housing. The clamping hook is secured to the other side of the other correspondingly rotated housing member to secure the housing member in the rotated position. These clamping hooks include simple fastening means that allow one housing member to be rotatably mounted to the other housing member and do not require additional assembly space.

Figure 1 shows a prior art auxiliary driver 2. The auxiliary driver 2 includes a gear unit housing 4, which is connected to the pole housing 6 of the electric motor. The rear surface of the gear unit housing 4 is closed by the gear unit housing cover 7 and the cover is shown in Fig.

The plug members 8 are disposed on the gear housing housing 4, the gear housing cover 7 and the pole housing 6 and the plug members are connected to the corresponding plugs of the connecting cable. The plug members 8 are provided for various positions in which the plug can be arranged. The gear unit housing 4, the gear unit housing cover 7, the pawl housing 6 and the plug members 8 disposed thereon are disposed in a fixed position and assembled into the vehicle in this position.

The position of the plug members 8 is determined by the respective cable harness wiring concept of the vehicle manufacturer, which is different for each vehicle type. Accordingly, the plug members 8 should be arranged in various ways as shown in Fig. Usually only one plug member 8 is provided on one of the housing members.

For each of the predetermined plug devices, one respective unique auxiliary driver 2 with a corresponding plug device must be provided. This results in considerable manufacturing labor, since various embodiments for the auxiliary driver 2 must be designed and manufactured. Special tools are required for each manufacturing process, which increases manufacturing costs.

Alternatively, the present invention provides a plug device, and an auxiliary driver 12, from which various plug devices can be achieved with one plug member 18.

3 schematically shows a first embodiment of an auxiliary driver 12 according to the present invention. The auxiliary driver 12 includes the gear unit housing 14 and the pawl housing 16 as housing members. After the pawl housing 16 is rotatably secured in the receiving portion 26, the gear device housing 14 is rotatably secured to the pawl housing 16. Alternatively, only one of the housing members may be rotatably formed and the other housing member may be stationary.

At least one plug member 18 may be disposed in the pawl housing 16 and / or the gear device housing 14, and the plug member is connected to the electrical functional member 20. This electrical function member 20 provided in the pawl housing 16 may be, for example, a brush holder, through which current is applied to the brush of an electric motor (not shown). Alternatively, the plug member 18 may be connected to a sensor, such as a Hall sensor, which is an electrical functional member 20, or to a conductor or contacts on a printed circuit board, for example, do. These are only a few examples for a plurality of electrical functional members 20. [

According to the present invention, the pawl housing 16 is rotatably formed. The pawl housing 16 includes at least one or a plurality of recesses 22 (shown in dashed lines in FIG. 3). A single recess 22 is sufficient to obtain the prescribed position. The pawl housing 16 is received in the receiving portion 26. The receptacle 26 includes at least one protrusion 24 as a coding and the protrusion can engage with the recesses 22 so that the pawl housing 16 can be fixed or disposed in a corresponding position . The recesses 22 are disposed in the pawl housing 16 at predetermined intervals to obtain predetermined plug devices, as will be described in more detail below with reference to Figs. 4 and 5. The receiving portion 26 may be fixedly disposed on an assembly line (not shown) or alternatively may be rotatably provided on an assembly line in a predetermined grid. In the latter case, it is sufficient that the receiving portion 26 includes only one protrusion 24 and the pole housing 16 includes only one recess 22. In both cases, after the pawl housing 16 is positioned in the receiving portion 26 in the predetermined rotated position, the pawl housing is connected to the gear device housing 14 so that the two housing members 14, 16 ) Are assembled in the vehicle. The accommodation portion 26 remains on the assembly line without being assembled into the vehicle.

Optionally, in addition to the pawl housing 16, the gear unit housing 14 is also rotatably formed and, conversely, as shown in Fig. In this case, the gear device housing 14 is preferably formed to be substantially rotationally symmetric, and Fig. 3 is schematic. The gear unit housing 14 includes a flange portion 28, which contacts the pole housing. At least one or a plurality of recesses (30) are provided in the flange portion (28). The recess 30 is indicated by a broken line in Fig. At least one hook member 32, for example a crimp hook, is provided on the pole housing 16 or on the wall of the housing and the crimp hook is connected to the corresponding flange portion 28 of the flange portion 28 of the gear device housing 14 May be received within the seth 30. 3 shows a hook member 32, for example. The gear device housing 14 is configured such that when the hook member 32 engages into the corresponding recess 30 and the gear device housing 14 and the plug member 18 connected to the housing are positioned in a predetermined, As shown in FIG. For example, a hook member 32, such as a crimp hook, is bent to secure the gear unit housing 14 to the position of the pawl housing 16. Various positions for the plug member 18 of the gear unit housing 14 are obtained by providing a plurality of recesses 30 that are preferably rotationally symmetric on the flange portion 28.

Unlike the pawl housing 16, in the case of the gear housing 14, the gear housing 14 is secured directly to the pawl housing 16 in a pivoted position without providing a separate receiving portion 26. This solution is particularly economical because additional accommodations can be omitted.

To obtain the various plug positions for the plug member 18 of the pawl housing 16, the receiving portion 26 includes a protrusion 24, as shown in Fig. 4, which protrudes, for example, May be received by a recess of one of the three recesses 22 of the pawl housing 16, respectively. Thereby, as shown in Fig. 5, the plug member 18 can be disposed at three different positions. In this case, the pawl housing 16 can be rotated until each of the recesses 22 engages with the projection 24 of the receiving portion 26 in the receiving portion 26. The pawl housing 16 is then connected to the gear unit housing 14 in a rotated position and separated from the receiving portion 26 to assemble a unit of the pawl housing and gear unit housings 16 and 14 into the vehicle. The receiving portion 26 and the housing members 14, 16 are shown very schematically in Figures 3, 6 and 7. Basically, one or optionally a plurality of recesses 22 may be provided in the pawl housing 16 to obtain a plurality of plug devices, depending on the purpose of use. The recesses 22 may be disposed in the pawl housing 16 regularly or irregularly, depending on the purpose of use. The receiving portion 26 is fixedly disposed on the assembly line. Alternatively, the receptacle 26 may be rotatably formed on the assembly line, so that in order to obtain a plurality of plug positions, the pawl housing 16 has only one recess 22 for securing, In this case, the accommodating portion 26 rotates correspondingly.

5 shows three plug devices in which one recess of each of the three recesses 22 of the pawl housing 16 is formed by engaging the protrusions 24 of the receiving portion 26. [ The advantage of this embodiment is that only one auxiliary driver 12 is provided for the plug devices and one auxiliary driver is not provided for one plug device, respectively. This is also applied to the plug member 18 of the gear unit housing 14 as well. Since the gear unit housing 14 and the pawl housing 16 are rotatably formed, further plug arrangements can be obtained, since the positions of the two housing members are mutually variable.

As shown in Fig. 6, in the second embodiment of the present invention, both the gear device housing 14 and the pawl housing 16 are rotatably connected to each other. The pawl housing 16 can be fixed in a rotated position within the receiving portion 26, as described with reference to Figs. The pawl housing 16 includes at least one recess 22 or a plurality of recesses 22 for this purpose and the receiving portion 26 may be rotatable or stationary on the assembly line. Accordingly, the receiving portion 26 includes at least one protrusion 24, and the protrusion can be inserted into the recesses 22. Rotation of the pawl housing 16 allows the protrusions 24 to engage the various recesses 22, thereby resulting in various arrangements of the plug member 18. Alternatively, the receiving portion 26 can be rotated to various positions where the protrusions 24 engage the recesses 22.

Optionally, the gear unit housing 14 may also be rotatably formed. To this end, the gear unit housing 14 is preferably formed substantially rotationally symmetrical, and only the portion of the gear unit housing 14 is shown in Fig. The flange portion 28 of the gear unit housing 14 rests on the wall of the pawl housing 16.

In this embodiment, the gear device housing 14 is fixed on the pawl housing 16 at a predetermined arbitrary position without being rotated by predetermined intervals. A clamping hook 36, for example, is used to secure the gear unit housing 14 in the rotated position, and the clamping hook engages corresponding openings 34 in the wall of the pawl housing 16. After the flange portion 28 of the gear unit housing 14 is rotated to a predetermined position, the clamping hook 36 engages the corresponding opening 34 and clamps with the flange portion 28. A plurality of openings 34 and corresponding clamping hooks 36 may be provided to securely secure the gear unit housing 14 to the pawl housing 16. An annular protrusion 27 may optionally be provided on the flange portion 28 to prevent the clamping hook 36 from inadvertently slipping away from the flange portion 28 and a clamping hook 36 ). In the embodiment shown in Fig. 6, the gear housing 14 and the pawl housing 16 can be rotated, whereby various plug devices for the plug members 18 are obtained on the housing members.

7 shows a third embodiment of the present invention. The gear housing 14 is formed in a stationary manner, while the pawl housing 16 is rotatably received in the receiving portion 26. The pawl housing 16 includes a protrusion 38 instead of a recess. The projections 38 are inserted into corresponding recesses 40 in the receptacle 26 to secure the pawl housing 16 in a predetermined,

The receptacle 26 includes at least one or a plurality of recesses 40. 9, for example, the receptacle may include five recesses 40 and protrusions 38 of the pawl housing 16 may be inserted into the recesses. The receiving portion 26 is fixedly disposed on the assembly line. Thereby, five plug devices for the plug member 18 connected to the pole housing 16 can be obtained. The pawl housing 16 may also include a plurality of protrusions 38 that are inserted into corresponding recesses 40 when the pawl housing 16 is rotated. Whereby the pawl housing 16 can be additionally supported in the radial direction. Alternatively, the accommodating portion 26 may be formed on the assembly line including only one recess 40 and rotatable at predetermined intervals.

The embodiments shown in Figs. 7 to 9 are not limited to the pawl housing but can also be applied to the gear device housing 14. The gear device housing 14 shown in Fig. 7 is fixed. However, the gear unit housing may be rotatably formed. As described in detail with respect to the embodiment of Figs. 3 and 6, the gear unit housing is preferably also formed in rotational symmetry and fixed to the pawl housing 16 in this case.

According to the present invention, at least one or both of the housing members are rotatably formed with respect to the other housing member. Here, a further rotatable or stationary housing may be used or the two housing members may be rotatably connected directly to one another.

As shown in Figures 1 and 3-9, the pawl housing 16 is preferably rotationally symmetrically formed. This facilitates rotation of the pawl housing 16 to secure it in its rotated position and assembly into the vehicle. This also applies to the gear device housing 14 when the gear device housing is also to be rotatably formed. In theory, the present invention is not limited to the case where the pawl housing 16 or the gear device housing 14 is rotatably formed. The gear unit housing cover 7 (FIG. 2) including other parts, for example, including the plug member 8, may also be rotatably formed to form various plug devices. Wherein the gear housing housing cover 7 is rotatable relative to the gear housing housing 14 in a similar manner to the previously described embodiments of Figures 3 and 6 in which the pawl housing 16 and the gear housing 14 are rotatably directly connected to one another. .

In the described embodiment, the pawl housing 16 can be inserted into the stationary receiving portion 26 at various prescribed positions to provide various plug member positions. Alternatively, the pawl housing 16 and the receiving portion 26 may be formed such that the pawl housing 16 can be inserted into the receiving portion 26 at only one prescribed position. 4, the pawl housing 16 includes only one recess 22 and the receiving portion 26 includes only one protrusion 24 and the protrusions are formed in the recess 22, Lt; / RTI > The receiving portion 26 is preferably disposed on the assembly line so as to be rotatable at predetermined intervals. This prevents the operator from placing the pawl housing 16 with the recess 22 in the receiving portion 26 so that the recess 22 is engaged with the wrong projecting portion 24 during the manufacture of one charge. do. Instead, the operator rotates the receiving portion 26 in a radial direction to a predetermined position to insert and fix the pawl housing 16. This applies correspondingly to all the embodiments described above in which the receptacle is used.
