Description

[0001] The invention relates to a charging device for a vehicle, in particular for charging a mobile phone.

[0002] DE 10 2017 210 641.7 discloses a charging device for a motor vehicle which has rod elements which are movable along a main extension direction by an actuating device, wherein the rod elements partially have an energy emission element.

[0003] DE 10 2011 110 680.8 shows a charging arrangement for a vehicle which includes an inductively chargeable mobile electronic device which can be charged via a coil.

[0004] One of the purposes of the invention is to provide a new charging device.

[0005] The problem is solved by the subject matter of claim 1.

[0006] A vehicle charging device for charging a mobile phone comprises an induction device, a plurality of boundary elements, and a storage area for a mobile phone. The induction device includes an induction plate and at least one induction loop associated with the induction plate. The induction plate forms a first area of ​​the storage area on its outer side and is slidably guided between an outer and an inner induction plate position. The boundary elements, each forming a second area of ​​the storage area at an outer first end, are arranged outside the induction plate and are slidably guided between an outer and an inner boundary element position. The provision of an induction plate enables the use of an induction loop with good efficiency.Because both the induction device and the limiting elements are movable between an outer and inner position, a well-defined support surface is created, and when a mobile phone is placed on it, the limiting elements can hold it laterally in a predetermined position. Different sizes of mobile phones can be held laterally by the limiting elements.

[0007] According to a preferred embodiment, the limiting elements are arranged around the induction plate. This allows a placed mobile phone to be held in place in all directions along the surface.

[0008] According to a preferred embodiment, the induction plate and the induction loop are slidably guided. This design ensures that the distance between the induction plate and the induction loop remains the same or at least similar when the induction device is moved.

[0009] According to a preferred embodiment, a first spring element is associated with the induction plate, which is designed to exert a force on the induction plate in an outward direction. This allows the induction plate to move automatically outwards when no mobile phone is placed on it. This reduces the height difference to the boundary elements when no mobile phone is present.

[0010] According to a preferred embodiment, each limiting element is associated with a second spring element, which is designed to exert an outward force on the induction plate. This force allows those limiting elements not subjected to the mobile phone load to move outwards and act as stops.

[0011] According to a preferred embodiment, the charging device is oriented such that an object placed on the outside of the induction plate and the boundary elements allows gravity to cause the induction plate and the boundary elements to shift. The storage surface must therefore be at least partially directed upwards, and it need not be horizontal but can also be inclined.

[0012] According to a preferred embodiment, the charging device is designed to form a stop when a first limiting element is in the inner limiting element position and a second limiting element adjacent to the first is in the outer limiting element position. This stop is designed to limit the movement of a mobile phone along the charging surface towards the stop. This design prevents mobile phones of different sizes from moving along the charging surface.

[0013] According to a preferred embodiment, the first area is at least 10 times larger than the second area of ​​at least one part of the boundary elements, preferably 30 times larger, and particularly preferably 50 times larger. This allows, on the one hand, a comparatively large induction loop, and on the other hand, a mobile phone can be held quite precisely in its position by the comparatively small boundary elements.

[0014] According to a preferred embodiment, the outer surface of the induction plate in the outer induction plate position and the outer first ends of the boundary elements adjacent to the induction plate in the outer boundary element position are arranged at the same height in order to avoid steps between the induction plate and the adjacent boundary elements. This design allows the mobile phone to be easily positioned on the surface.

[0015] According to a preferred embodiment, the outer first ends of the boundary elements have at least a partially hexagonal shape, and the boundary elements are at least partially surrounded by six further adjacent boundary elements. This arrangement allows for a large ratio between the closed portion of the storage area and the open portion, for example, by gaps. Furthermore, the individual boundary elements can be protected from strong tilting movements by the surrounding boundary elements, as the surrounding boundary elements can act as guides. The outermost boundary elements, for example, are not surrounded by six further boundary elements.

[0016] According to a preferred embodiment, the charging device has guide elements, and the limiting elements or the induction device each have a recess into which the guide elements project at least partially to guide the limiting elements or the induction device during displacement. This results in a guide that is easy to mount.

[0017] According to a preferred embodiment, the guide elements have a hexagonal cross-section at least in some areas, and the recesses also have a hexagonal cross-section at least in some areas. This prevents incorrect assembly, as the hexagonal cross-section correctly defines the position.

[0018] According to a preferred embodiment, the charging device has guide elements that define a recess. The limiting elements or the induction device project at least partially into the recess, at least in certain areas, to guide the limiting elements or the induction device during displacement. This design is very stable because the sections can be made relatively large.

[0019] According to a preferred embodiment, the induction plate has at least four recesses or at least four sections designed to interact with the guide elements. The at least four recesses or sections reduce the risk of the mobile phone tipping when placed on the plate.

[0020] According to a preferred embodiment, the recesses or sections of the induction plate are formed in the edge region of the induction plate. This reduces the risk of the induction plate tipping over.

[0021] According to a preferred embodiment, a vehicle has such a charging device. Due to the acceleration that occurs, the charging device is particularly advantageous in vehicles.

[0022] Further details and advantageous embodiments of the invention will become apparent from the exemplary embodiments described below and illustrated in the drawings, which are in no way to be understood as limiting the invention, as well as from the dependent claims. It shows Fig. 1. In a spatial representation, a charging device in a first state, Fig. 2 in a spatial representation the charging device of Fig. 1 in a second state, Fig. 3. A further embodiment of the charging device is shown in a three-dimensional representation. Fig. 4 a detail IV of Fig. 3, Fig. 5 in a spatial representation another embodiment of the charging device with a schematically depicted mobile phone placed on it, Fig. 6 in a longitudinal section through another embodiment of the loading device three limiting elements, Fig. 7 in a longitudinal section through another embodiment of the charging device three limiting elements, and Fig. 8 in a longitudinal section through a further embodiment of the charging device an induction device.

[0023] In the following, identical or similarly functioning parts are designated with the same reference symbols and are usually described only once. The description builds upon itself across figures to avoid unnecessary repetition.

[0024] Fig. Figure 1 schematically shows a vehicle 10 with a charging device 20 for a mobile phone provided in the vehicle 10. The charging device can be located, for example, in the area of ​​the center console or in the area of ​​the dashboard. The charging device can also be provided in the glove compartment.

[0025] The charging device 20 has an induction device 30 and a plurality of limiting elements 40 as well as a storage area 22 for a mobile phone.

[0026] The induction device 30 has an induction plate 32 and at least one induction loop 34 associated with the induction plate 32. The induction plate 32 forms a first area 31 of the storage surface 22 on an outer side 36, and it is located between an outer induction plate position 38 and an inner induction plate position 39 (see figure). Fig. 2) guided in a sliding manner.

[0027] The limiting elements 40 are arranged outside the induction plate 32 and are slidably guided between an outer limiting element position 51 and an inner limiting element position 52, cf. Fig. 6 and Fig. 7.

[0028] In the exemplary embodiment, the limiting elements 40 are arranged around the induction plate 32.

[0029] The induction loop 34 can also be called a coil, and it enables inductive charging of a mobile phone.

[0030] Fig. Figure 2 shows the charging device 20 of Fig. 1, wherein the induction device 30 is pressed downwards into an inner induction plate position 39. The downward or inward displacement of the induction device 30 can be effected, for example, by pressing down on the induction plate 32.

[0031] Fig. Figure 3 shows another embodiment of the charging device 20, in which the induction device 30 has an outer induction plate position 38.

[0032] Fig. 4 shows detail IV of Fig. 3, wherein the induction device 30 differs from that in Fig. 3 is in an inner induction plate position 39.

[0033] Four recesses 35 are provided in the edge region of the induction plate 32, and the limiting elements 40 also have recesses 43. The recesses 35 and 43 enable the induction device 30 and the limiting elements 40 to be guided, as shown in Fig. 6 to Fig. 8 is described in more detail.

[0034] In the exemplary embodiment, the recesses 35 are provided with a hexagonal base shape. This prevents incorrect assembly, as the hexagonal base shape of the recesses 35 corresponds to the hexagonal base shape of the boundary elements 40.

[0035] Fig. Figure 5 shows the charging device 20 with a mobile phone 100 placed on the storage surface 22, the mobile phone 100 being shown schematically and transparently. The weight of the mobile phone 100 causes the induction device 30 and the limiting elements 40 located under the mobile phone 100 to move downwards and inwards, respectively. Since limiting elements 40 are provided around the mobile phone 100, which are located in the outer limiting element position 51, these form a stop 44, which is designed to limit the movement of the mobile phone 100 along the storage surface 22 towards the respective stop 44. This prevents the mobile phone 100 from moving along the storage surface 22 towards the respective stop 44 when the vehicle 10 accelerates or brakes (see Figure 5). Fig. 1) The mobile phone slipped 100.

[0036] By placing the mobile phone 100 on the induction device 30, both safe storage of the mobile phone 100 and charging of the mobile phone 100 can be made possible.

[0037] Recesses 35 are provided in the edge region of the induction device 30, which enable the induction device 30 to be guided. In the exemplary embodiment, the limiting elements 40 have a hexagonal base shape. This allows for a storage surface 22 without large gaps, and the induction device 30 is well defined in its position and displacement by the outer limiting elements 40. The hexagonal base shape of the limiting elements 40 is advantageous and allows for the arrangement of six further adjacent limiting elements 40 around the respective limiting element 40. Alternatively, a square or round base shape would be possible, for example.

[0038] In the exemplary embodiment, the induction device 30 has hexagonal edge elements 70 at its periphery, each of which contains one of the recesses 35. The edge elements 70 are those hexagonal elements that directly adjoin the large surface of the induction device 30. The edge elements 70 are fixedly connected to the induction device 30 or formed integrally with it, and this allows the induction device 30 to be guided by the edge elements 70 in the same way as the boundary elements 40. This simplifies manufacturing.

[0039] Fig. Figure 6 shows a schematic longitudinal section through the charging device 20, illustrating three of the limiting elements 40A, 40B, and 40C. Each of the limiting elements 40A, 40B, and 40C forms a second area 42 of the storage surface 22 at an outer first end 41. This allows for the storage of a mobile phone 100 (see Figure 6) in a specific way. Fig. 7) A force F is exerted on the limiting element 40A. This force F allows the limiting element 40A to be moved from the outer limiting element position 51 to the inner limiting element position 52. The loading device 20 has guide elements 48 which project at least partially into the recess 43 of the respective limiting element 40, thereby enabling guidance during the movement of the limiting elements 40 in a guide direction 49. The guide direction 49 is preferably parallel for all limiting elements 40, but it can differ in various sub-areas.

[0040] Spring elements 46 are provided in the inner area of ​​the limiting elements 40, which exert a predetermined outward force on the limiting elements 40. The spring force of the spring elements 46 is preferably such that the limiting elements 40 remain in the outer limiting element position 51 without an external force F, but that when a mobile phone 100 is placed on them, the weight force is sufficient to cause the limiting elements 40 to move into the inner limiting element position 52. The recesses 43 can be designed as through-holes, as shown on the left and in the middle, or as blind holes open to the inside, as shown on the right. The blind hole design has the advantage that no dirt or liquids can penetrate the recesses 43 from the outside.

[0041] Fig. Figure 7 shows a further embodiment of the charging device 20, in which guide elements 54 are provided, each defining a recess 56. The limiting elements 40 project at least partially into the recess 56 with a section 60 to guide the limiting elements 40 during displacement. The schematically depicted mobile phone 100 rests against the stop 44, which is formed by the limiting element 40B.

[0042] The induction plate 32 can be guided in the same way.

[0043] Fig.Figure 8 shows the charging device 20 in a longitudinal section. The illustration is foreshortened in the central area, and the induction device 30 is preferably wider than it is tall. The induction loop 34 is integrated into the induction device 30, and the induction plate 32 can therefore be moved together with the induction loop 34. The induction plate 32 is associated with at least one spring element 33, which is designed to exert a force on the induction plate 32 in an outward direction.

[0044] As with the limiting elements 40, recesses 35 and guide elements 48 are provided which enable the induction device 30 to be guided in a guide direction 49 during movement. The guide direction 49 of the induction device 30 is preferably parallel to the guide direction 49 of the limiting elements 30 in order to achieve uniform movement, but it can also be inclined for this purpose.

[0045] The first area 31 is preferably at least 10 times larger than the second area 42 at the first end of the respective boundary element 40, preferably 30 times larger, and particularly preferably 50 times larger. In the outer induction plate position 38, the outer surface 36 of the induction plate 32 is preferably at the same height as the outer first ends 41 of the boundary elements 40 adjacent to the induction plate 32, in order to avoid steps between the induction plate 32 and the adjacent boundary elements 40. This allows the mobile phone 100 to be positioned and moved along the storage surface 22 until it is actually placed on the storage surface 22.

[0046] In the exemplary embodiment, the right-hand recess 35 is closed by a closure 37 on the outer surface 36 of the induction plate 32, thus preventing dirt from entering the recess 35. This makes the recess 35 a blind hole, and this result can also be achieved by designing the recess 35 as a blind hole from the outset, rather than as a through-hole.

[0047] Naturally, various variations and modifications are possible within the scope of the present invention.

[0048] In addition to or as an alternative to the spring elements, an adjustment device can be provided which enables controlled adjustment of the individual limiting elements 40, preferably also of the induction device 30. This allows for a defined setting of the charging device for different types of mobile phones. The type can be entered, for example, by the user, or it can be done automatically by evaluating wirelessly transmitted data (e.g., Bluetooth, WLAN, GSM) or by optically scanning the size of the mobile phone.
