Technical Field

The present invention relates to a holding device for holding an electrical charging device according to the preamble of claim 1. The invention also relates to a holding system, a motor vehicle comprising a holding device, and a method for mounting a charging device using a holding device.

Background

As described in WO 2014/053221 a1, differently configured charging devices may be required for vehicles having an electric drive. Such a demand arises, for example, from country-specific standards relating to charging stations or different vehicle systems. According to the technique described in WO 2014/053221 a1, the charging device is constructed as a modular system. The intermediate module is provided with general versatility and is used for fixing on a vehicle. The intermediate module has an interface on the input side and an interface on the output side for the installation of end modules which can be selected from different modules.

A disadvantage of the technique described in WO 2014/053221 a1 is that a compact construction of the charging device is difficult to achieve by means of a modular embodiment. Furthermore, for all applications of the charging device, the same fastening of the intermediate module to the vehicle body is used, so that it is difficult to optimize for different vehicle types. In addition, the intermediate module of the charging device needs to be directly fixed on the vehicle body, which increases the difficulty of mounting the charging device.

DE 102011004834 a1 describes a charging device for an electric vehicle, in which an adapter board is provided in order to attach standardized electrical components to different vehicle bodies.

The technique described in WO 2014/053221 a1 has the disadvantage that the adapter plate needs to be screwed to the electrical component, so that the installation of the charging device is likewise difficult.

Detailed Description

Fig. 1 is a schematic view of a holding device 100 for holding an electrical charging device (not shown). The holding device 100 is suitable for holding a charging device for an electrically driven automobile, for example.

The holding device 100 comprises a base plate 110, on the top side 112 of which several hooks 114 are provided. The catch 114 is adapted to engage with a snap profile of the charging device when the charging device is held in the holding device 100. In the illustrated example, the catch 114 is disposed in the base plate 110 around a gap 116. By means of the cutout 116, the side of the charging device facing the top side 112 can be accessed from the bottom side of the holding device 100. Furthermore, the base plate 110 comprises several fixing elements 118 for fixing the holding device 100 and, as the case may be, a charging device held in the base plate, for example on the body of an electrically driven motor vehicle.

The retention device 100 also includes a locking frame 150. The locking frame 150 is movably installed on the base plate 110. In the example shown, the latching frame 150 substantially encloses the latching hook 114, wherein the latching frame 150 is movable in the vertical direction relative to the base plate 110.

The lock frame 150 includes a plurality of operating pieces 158. The handle tabs 158 facilitate manual movement of the lock frame 150 relative to the top side 112 of the base plate 110. Furthermore, the locking frame 150 has at least one locking hook 160 which is adapted to engage with a locking snap profile of the charging device.

The locking frame 150 has a recess 156 in the region of each of the hooks 114 and, adjacent to each of the recesses 156, a tensioning profile 152 and a locking profile 154, respectively. Furthermore, the locking frame 150 is arranged such that in the position shown, each of the hooks 114 extends partially into a corresponding recess 156 of the locking frame 150. Wherein each catch 114 also bears with the outside against the locking contour 154. Furthermore, each of the hooks 114 rests with the inner side of the section which projects into the recess 156 on a corresponding tensioning contour 152 of the locking frame 150.

The lock frame 150 is movable relative to the base plate 110 between a first position and a second position, such as by pulling on the operating tab 158. In the first position, the locking frame 150 is lowered. In this case, the locking frame 150 abuts, for example, onto the top side 112 of the base plate 110. In this position, each of the tensioning profiles 152 tensions the catch 114 abutting there outwards into the open position. To this end, in the example shown, each of the tensioning profiles 152 has an outwardly inclined profile which presses the upper section of the latching hook 114 outwards. Furthermore, each of the notches 156 in this case provides the space required for tensioning the catch 114 into the open position.

Based on the first position of the locking frame 150, the charging device can be inserted into the holding device 100 in a simplified manner, for example without any force. In particular, the force required to open the catch 114 need not be applied, or only partially applied, during installation. For example, the fitting operation may be performed after the holding device 100 is fixed to the vehicle body.

The lock frame 150 may be moved from the first position to the second position, for example, by pulling on one or more of the tabs 158. In the second position, the locking frame 150 is further away from the top side 112 of the base plate 110. At the same time, the lock frame 150 is partially pulled out from the hook 114. This results in the hook 114 being bent to a lesser extent in the second position than in the first position as a result of the tensioning profile 152. In this way, the catch 114 enters the closed position during movement of the locking frame 150 from the first position to the second position. For this purpose, the latching hook 114 can be made of an elastic material, for example an elastic plastic, and is prestressed in the closed position. Furthermore, in the second position of the locking frame, the locking contour 154 abuts in a outwardly abutting manner against the upper region of the latching hook 114. The locking profile 154 thereby prevents the catch 114 from bending outwards. Thereby locking the catch 114 in its closed position.

If a suitable charging device is inserted into the holder 100, while the locking frame 150 is in the first position, the movement of the locking frame 150 into the second position causes the catch 114 to engage with the locking contour of the charging device in the manner described. At the same time, the thus formed engagement is locked by the locking frame 150, preventing the release of accidental separation. Furthermore, the locking hook 160 can lock the locking frame 150 in the second position by engaging with a locking snap profile of the charging device. This prevents the locking frame 150 from accidentally moving back to the first position and thus prevents accidental opening of the catch 114.

Fig. 2 is an exploded view of the holding device 100. Wherein the base plate 110 is shown separated from the locking frame 150. As hereinafter, the same reference numerals as in fig. 1 are used here to denote the same features of the retaining device 100.

Fig. 2 shows in particular a recess 156 in the locking frame 150, and the contour formed by the tensioning contour 152 and the locking contour 154 adjoining the recess 156. In addition, the arrangement of the latching hook 160 on the locking frame 150 can be seen. The locking hook 160 causes the locking frame 150 to be engaged with the embedded charging device, and the hook 114 is used to engage the base plate 110 with the charging device.

It can also be seen that in the example shown, the top side 112 of the base plate 110 is countersunk relative to the fixing element 118. This facilitates, for example, the protection of the held charging device by the base plate 110 or the installation of the holding device 110 in a motor vehicle. In other examples, the bottom plate 110 is otherwise constructed, for example, having a different arrangement of the top side 112 relative to the securing elements 118 than the illustrated sunken arrangement of the top side 112. In addition, other examples of retention devices 100 have fixation elements that are different than the fixation elements 118.

The holder 100 may be used for mounting in any orientation, for example in an electrically powered car. The orientations shown, as well as the spatial concepts used herein, such as "top side", "above", "upper", "bottom side", "lower", "vertical", etc., are merely used to illustrate the position and orientation of the elements in question with respect to each other, and should not be construed as limiting the layout or orientation of the holding device as a whole. In some examples, a charging device suitable for use with the holding device 100 has, in particular, contact elements on a side of the charging device facing the top side 112 of the base plate 110 for making contact by a charging power source. Furthermore, in some of these examples, the holding device is mounted in the vehicle in such a way that the opening 116 and the contact element of the charging device that can be accessed by it face one side of the vehicle, for example the front side.

Fig. 3A to 3C are fragments of cross-sectional views of the holding device 100 in different positions, in conjunction with the mounting of the electrical charging device.

Fig. 3A shows the holding device 100 in the region of the latching hook 114. In this case, the locking frame 150 is in the first position, i.e., near the top side of the base plate 110. It can be seen therein that in this position of the locking frame 150 the latching hook 114 is tensioned by means of the tensioning profile 152 into the open position. As described in connection with fig. 1, the upper section of the latching hook 114 in this case projects partially into the recess of the locking frame 150. It can furthermore be seen that in this position of the locking frame 150 the locking contour 154 allows a bending of the latching hook 114, since the locking contour 154 does not bear against the outside of the latching hook 114 in the upper region of the latching hook 114.

Fig. 3B shows the holding device 100 in the same position as in fig. 3A. Fig. 3B also shows charging device 200 embedded in holding device 100. The charging device 200 has a latching contour 210 in the region close to the catch 114, which is adapted to engage with the catch 114. The charging device 200 can be inserted almost without applying force based on the open position of the hook 114. An easy pre-engagement of the latching contour 210 with the catch 114 and/or the locking frame 150 takes place in the example shown. In some examples, this simplifies installation of the charging device 200. In the illustrated example, the charging device 200 is constructed to extend partially through the cutout 116 in the base plate 110.

Fig. 3C shows the holding device 100 with the charging device 200 embedded, as described in connection with fig. 3B. But differs from the arrangement shown in fig. 3B in that the lock frame 150 is in the second position. As described in connection with fig. 1, the movement of the locking frame 150 from the first position into the second position causes the latching of the catch 114 with the latching contour 210 and at the same time causes this latching to be locked by the locking contour 154, which now in the higher section bears against the outer side of the catch 114 and thereby prevents a bending of the catch 114. Furthermore, in the movement of the locking frame 150 into the second position, the engagement of the locking hook 160 with the locking snap profile of the charging device 200 occurs. This locks the lock frame 150 against accidental movement in the second position.

Fig. 4 is an exploded view of a retention system 300 for mounting a charging device, such as in an automobile. The retention system 300 includes the base plate 110 and the locking frame 150, which together make up the retention device 100 as previously described. The retention system 300 further includes an electrical charging device 200 adapted to be retained by the retention device 100. To this end, the charging device 200 includes a snap profile 210, and the hook 114 of the base plate 110 is adapted to be engaged with the snap profile 210. Electric charging device 200 is a charging device for an electrically driven automobile, for example.

Fig. 5A to 5C are different schematic views of the retention system 300 in an assembled state.

Fig. 5A is a perspective view of retention system 300. It can be seen that the charging device 200 is partially surrounded by the base plate 110 and by the locking frame 150. In the case of the illustrated charging device 200, contact areas for contacting by means of a charging power source are provided on the underside of the charging device 200, which contact areas are accessible by means of the cutouts 116 of the base plate 110.

Fig. 5B is a top view of retention system 300. The arrangement of the fixing element 118 relative to the base plate 110 and the arrangement of the operating element 158 of the locking frame 150 relative to the base plate can be seen.

Fig. 5C is a bottom view of retention system 300. Several contact elements 214 are shown on the bottom side of the charging device 200. The contact elements 214 are accessible through the cutouts 116 of the base plate 110, for example for making contact with a charging power source. Furthermore, an adjusted arrangement of the cutouts 116 and the contact elements 214 relative to one another can be seen. In the example shown, the plugging direction of the charging device extends parallel to the direction of extension of the latching hook 114 of the holding device. This helps to improve the stability of the retention system 300, for example during the process of making or breaking a plug-in connection with a charging power supply.

Fig. 6 is a schematic view of an automobile 600. The automobile 600 includes a retention system 630 for retaining an electrical charging device as previously described. The holding system 630 comprises in particular a holding device 610 and an electrical charging device 620 held in the holding device 610. The electrical charging device 620 is suitable, for example, for charging an energy store in the vehicle 600 for driving the vehicle 600 by contact with a charging power source.

Fig. 7 is a flow chart of a method 700 of installing a charging device in an automobile. The charging device is, for example, a charging device for charging an energy store in a motor vehicle as described above.

The method 700 includes providing a holding device, step 710. The holding means are for example as described in connection with the previous figures. The method 700 further includes providing a charging device, step 720. The charging device has at least one latching contour, and the at least one hook of the holding device is adapted to engage with the latching contour of the charging device. The method 700 further includes securing 730 the retaining device to the body of the vehicle. After securing the holding device, the method 700 includes disposing the charging device in the holding device, step 740. During the arrangement of the charging device in the holding device, the locking frame of the holding device is in the first position. The method 700 further includes moving the locking frame into a second position, step 750. This operation is performed in such a manner that the hook of the holding device is lockingly engaged with the snap profile of the charging device.

With the aid of the aforementioned technology, the charging device can be installed in a motor vehicle in a simple manner, for example without force. Since the charging device fitted into the holding device can be easily pre-engaged, the mounting of the charging device can be further simplified. The technique simultaneously ensures a reliable connection of the charging device with the retaining device. Furthermore, the technology is widely used. In particular, when the same charging device is used with different vehicle types, only different chassis need be provided for the holding device as the case may be in order to optimize the application. At the same time, the technology can be used with different charging devices, wherein, as the case may be, only a correspondingly constructed base plate and/or locking frame need be provided.
