Description

[0001] The invention relates to a charging socket device for an electric vehicle or a hybrid vehicle, the charging socket device having a first multi-pole socket, a second two-pole socket and a movable charging cover. The sockets form the charging socket device and are arranged together in a charging slot of a motor vehicle body, and the charging slot can be covered by the charging cover.

[0002] Such a charging socket device is preferably integrated into the body of the motor vehicle and is in most cases arranged in a protected manner behind a movably arranged charging cover. The charging cover serves on the one hand to prevent misuse of the charging socket device and on the other hand to protect the charging socket device from environmental influences. The charging socket device is used in different design variants. The invention relates to a charging socket device having a first socket for an AC voltage and a second socket for a DC voltage connection. The sockets differ in the number of poles provided and primarily in the provision of different charging currents for the motor vehicle.

[0003] The charging socket device according to the present invention has a combined structure consisting of a multi-pole socket and a two-pole socket. Such a socket is used for a dual-type plug for DC charging and AC charging and is known as an EU standard plug connector. The charging socket device is fixedly arranged in the charging slot of the motor vehicle so that the operator can insert the charging plug into the charging socket device of the charging slot. In order to close the charging slot and thus to cover the charging socket device, different solutions are known from the prior art.

[0004] DE 202021 901 685 U1 discloses a movement and pivoting device for a vehicle cover covering a charging socket device. In order to release the charging socket device (also referred to herein as an interface or charging module), the vehicle cover can first be moved by means of a movement device and then pivoted by means of a pivoting device. Thus, the charging socket device is released by a linear movement of the vehicle cover and a subsequent pivoting.

[0005] DE 10 2020 209 607 A1 discloses a closing assembly for closing a fuel tank compartment of a motor vehicle body, wherein a cover element is movable in the body in a manner that can be moved by means of a linear drive. The closing assembly performs two different movements. To open the charging compartment, the charging cover or the cover element is first moved by means of a lifting movement, so that it then performs a longitudinal movement and thus releases the charging socket device.

[0006] From the unpublished DE 10 2021 116 318.8, a device for closing a charging device of an electric vehicle or a hybrid vehicle is known, which has: a plug half arranged in the vehicle and connected to another plug half; an electrically drivable closing device, wherein in the non-operated state of the plug half, the opening of the charging device can be closed by means of the closing device, and the closing device can be mechanically engaged with the other plug half inserted into the plug half, wherein the position of the closing device can be detected by means of a sensor. In two different embodiments, it is described that the charging cover is movably arranged so that the charging socket device or the charging slot can be at least partially closed even during the charging process.

[0007] The solutions known from the prior art have proven themselves in principle. However, the prior art reaches its limits in terms of protecting sockets that are not needed. In particular, when charging is necessary under weather and / or environmental influences, when charging is carried out using one socket, the other socket can only be protected to a limited extent from environmental influences and from being misused. The present invention takes this as its starting point and intends to improve upon this.

[0008] The object of the present invention is to provide an improved charging socket device for an electric vehicle or a hybrid vehicle. In particular, the object of the present invention is to protect the socket that is not needed, so that the reliable operation of the charging process can be ensured as a whole.

[0009] This object is achieved according to the invention by the features of independent claim 1. Advantageous embodiments are given in the dependent claims. However, it should be pointed out that the exemplary embodiments described below are not restrictive, but rather any possible variations of the features described in the description, claims and drawings are possible.

[0010] According to claim 1, the object of the present invention is achieved by providing a charging socket device for an electric vehicle or a hybrid vehicle, a first multi-pole socket, a second two-pole socket and a movable charging cover, the sockets forming the charging socket device and being arranged together in a charging slot of a motor vehicle body, the charging slot being coverable by means of the charging cover, and the sockets, preferably the second two-pole socket, being individually closed. Now, by means of the structure of the charging socket device according to the invention, it is possible to partially close the charging socket device, so that the socket can be kept closed during charging. This provides a number of advantages which are described in detail below in the corresponding embodiments.

[0011] The main advantage of the design of the charging socket device according to the invention is that the second socket that is not used for charging is closed during the charging process. The unused socket is thus protected from environmental influences and, moreover, from improper misuse. Thus, in the case of moisture or condensation, for example in the form of rain or snow, moisture cannot enter the other socket. The charging cover usually covers and / or seals the charging slot, but cannot or can only partially close the charging slot when the charging plug is inserted. By using a separately existing cover for the socket that is not relevant to the charging process according to the invention, it can be ensured that the other socket is reliably and completely closed and is therefore protected during the charging process.

[0012] The charging socket device according to the present invention is applied to motor vehicles, such as passenger cars, light trucks, land transport vehicles, commercial vehicles, etc. Of course, these examples are not restrictive, and more specifically, the charging socket device can be used in any position of an electric vehicle equipped with an electric vehicle battery or a vehicle or a transportation vehicle with a hybrid drive device. It can also include unmanned transportation vehicles, such as buses, working machinery, etc.

[0013] As described above, the charging socket device has two sockets, namely, a socket that can be charged using an alternating voltage (AC) and a second socket that can be charged using a direct voltage (DC). Such sockets are known and certified, for example, by EU standards. The sockets are arranged side by side in the charging slot. This has the advantage that the charging slot can be closed by a charging cover, so that, for example, a passenger car can form a flat surface with the charging cover. Here, the term "charging slot" should not be understood restrictively, but can also include other openings or charging cavities of the vehicle. For example, if the charging socket device is installed in the luggage compartment of the vehicle, the charging slot can be designed as a luggage compartment, for example, and the charging cover can be formed by a luggage compartment cover. It is important for the present invention that at least one socket, preferably the second DC voltage socket, can be closed individually.

[0014] If the second socket can be closed or covered by means of a cover, an advantageous design variant of the invention is obtained. The advantage of "closing the other socket by means of a cover" is that the socket can be closed in a sealed manner. The cover can be completely placed against the socket and thus prevent the intrusion of environmental influences. In this case, the cover can follow the shape of the socket and thus ensure protection for the socket with the smallest possible structure. In this case, the cover serves as a protective structure, so that the cover can also be called a protective cover or protective cover or cover plate. In this case, the task of the cover is to close the socket in a sealed manner on the periphery.

[0015] Advantageously, the cover is made of plastic. The advantage of plastic is that it is lightweight, can be designed in any form in the simplest form, and, as a cost-effective material, has a positive effect on the costs of the charging socket device. It is also conceivable that the cover has a seal, wherein the seal can be designed circumferentially on the edge of the socket. The seal can be mounted integrally on the cover or designed as a fixed component of the cover. In this case, the cover can be designed, for example, as a two-component component.

[0016] If the second socket can be closed in such a way that the charging plug can be inserted into the first socket, an advantageous design variant of the present invention is obtained. The cover closes the socket in such a way that the first socket can be freely accessed and can be used as a socket. Charging can therefore be carried out via the first socket, wherein the charging cover is preferably designed so that it follows the shape of the opening of the first socket. Therefore, the first socket is completely surrounded by the housing and the cover of the charging socket device, thereby providing the operator with a first socket that can be fully opened. In other words, the cover follows the shape of the opening of the first socket. The advantage is that the plug inserted into the first socket is completely sealed. Therefore, dirt and / or moisture cannot enter either the second socket or the first socket during the charging process.

[0017] In another design variant of the invention, the cover can be operated in an electrically driven manner. The cover can be moved by means of an electric drive, preferably by means of an electric drive and at least one transmission stage. Electrical energy is provided in the motor vehicle so that the movement can be introduced into the cover by means of a micro drive. In this case, the cover can perform a linear movement, or can be swiveled, or can perform a combination of linear and swiveling movements, for example. In this case, depending on the arrangement of the cover, the cover preferably passes through the second socket and finally rests sealingly against the opening of the second socket.

[0018] In another design variant of the present invention, the cover can be lifted from the second socket by means of a lifting movement and can be moved away from the region overlapping the second socket by means of a second pivoting movement. The combined lifting and pivoting movements achieve the best possible seating of the cover on the opening of the second socket. The cover covers the opening of the second socket in such a way that a sealed covering can be achieved. However, it is also conceivable according to the present invention that the cover is inserted into the opening of the second socket in a form-fitting manner, so that the cover is flush with the housing of the charging socket device.

[0019] It is also conceivable that, for example, a circumferential recess is arranged in the housing of the charging socket device, into which the cover can be inserted. In this case, the contact with the housing of the charging socket device can be released by a first lifting movement in order to then enter the area in which the cover can be swung. The angle of the swiveling movement can be greater than 90°, preferably 120°, so that the cover can be swung completely out of the opening area of ​​the socket. In the case of a linear movement and / or a swiveling movement and / or a tilting movement of the cover, the cover always moves to such an extent that the second socket is freely accessible.

[0020] In an advantageous structural design variant of the invention, the cover is connected to a drive shaft, wherein the drive shaft can be manipulated by means of a drive wheel. The drive shaft is preferably arranged at the lateral end of the cover, so that a swinging movement of the cover can swing the cover out of the opening area of ​​the socket. By using the drive shaft, it is achieved that the electric drive device is arranged spaced apart from the socket area, so that a structurally advantageous and space-saving arrangement of the electric drive device can be achieved. The drive wheel cooperates with the drive shaft, wherein the drive wheel acts by means of an electric motor and a downstream transmission. In this case, the drive wheel can achieve an axial movement of the drive shaft and a rotational movement of the drive shaft. The drive shaft itself preferably extends along the socket, so that the drive mechanism can be arranged in the area behind the socket.

[0021] If the drive shaft has a control profile, by means of which the cover can be moved linearly, a reliable, rapid and accurate movement of the cover can be achieved. In this case, the drive shaft and the drive wheel cooperate in such a way that a linear movement of the drive shaft can be achieved by means of the control profile mounted on the drive shaft. In this case, the drive wheel can be coupled to the control profile in such a way that the drive shaft can be moved along its center axis. For this purpose, the drive shaft is supported in a linear guide of the housing in a pivotable and linearly movable manner.

[0022] In the continuation of the inventive concept, the drive shaft has at least one stop, and the linear guide has an idle zone, wherein the swinging motion of the charging cover can be limited and guided by means of the stop. In relation to the embodiment, the drive shaft can also be referred to as a control shaft that acts together with the linear guide. A stop and a guide device are provided on the drive shaft, which can generate a linear motion under the guidance of the linear guide. After the cover is erected, the stop reaches the stop point in the linear guide, thereby terminating further linear motion. At the same time, the stop reaches the idle zone, and the drive shaft can swing through the idle zone. Therefore, the linear guide also serves as a guiding structure for the swinging motion. If the swinging motion is achieved by further driving the drive wheel, the drive wheel reaches the stop surface along the control profile of the drive shaft, and the drive shaft can be swung by means of the stop surface. If the drive shaft is moved linearly by the control profile of the drive shaft, the swinging motion can be introduced into the drive shaft by means of the drive wheel at the same time. Therefore, the drive wheel, the drive shaft and the guide in the housing can achieve the lifting motion of the cover, and can swing the cover away from the opening area of ​​the socket.

[0023] In another design variant of the present invention, the drive wheel has at least one additional stop and / or at least one locking device, so that the closing movement of the cover can be achieved by means of the drive wheel. The drive wheel can, for example, move the cover back to its initial position by means of a return movement. For this purpose, the drive wheel has a locking device, or cooperates with the locking device in the following manner, that is, when the final position of the cover is reached, that is, in the fully swung position, the locking device is locked into the profile of the drive shaft. If the drive wheel is moved back by means of an electric drive device, the swinging movement of the cover can be guided in a linear guide or a swinging guide until the final position is reached. As the linear portion of the linear guide is reached, the locking device is disengaged, and the drive wheel can be moved back to the initial position again in a straight line by another control profile on the drive shaft. In this case, the cover closes the socket again. The structure of the charging socket device according to the present invention achieves that the socket is protected even during the charging process, so that the charging socket device can be used reliably and for a long time.

[0024] In another design variant of the invention, the drive wheel is designed as part of a screw drive. The advantage of a screw drive is that a very uniform and precise linear movement can be generated. The screw drive also exhibits high smoothness and thus enables a continuous movement of the drive shaft. Thus, the adjustment movement of the cover can be realized with the simplest structural measures and with a minimal structure.

[0025] The drive with the smallest structure and thus the advantageous design is achieved in particular when the drive shaft is designed as a spindle nut and the drive wheel is designed as a spindle. The drive shaft is thus used directly as a transmission component, whereby the smallest possible number of components are required to provide a linear drive. Furthermore, by designing the drive shaft as a spindle nut, a very precise and uniform movement of the cover can be achieved. Furthermore, a large adjustment force can be achieved with the spindle drive, so that weather influences, such as icing, can also be eliminated and thus adhesion of the cover can be eliminated.

[0026] The drive shaft itself can be moved, in particular linearly and rotationally, by means of the guide element. As in the first embodiment, the drive shaft can be linearly and rotationally guided by means of the guide element. For this purpose, the guide element has a linear groove in which the drive shaft can be linearly moved and at least one further groove, by means of which the rotational movement of the drive shaft can be guided. The guide element thus determines the movement of the drive shaft and thus the position of the cover, which is connected to the drive shaft in such a way that the cover follows the movement of the drive shaft.

[0027] The movement of the drive shaft can be realized by means of a guide device. Here, the drive shaft has a guide device, in particular a stop, wherein the drive shaft can move in the guide element by means of the guide device. This movement is introduced into the drive shaft by means of a screw drive. The guide device is a part of the guide element or acts together with the guide element. The guide device can be designed as a groove or a protrusion, for example, and acts together with the guide element in the following manner, that is, the drive shaft performs a linear motion and / or a swinging motion. For this purpose, for example, a stop can be constructed on the drive shaft as a guide device, so that the stop forms a protrusion on the drive shaft. In this case, the stop itself is guided in a guide element, for example a linear groove, so that the movement introduced into the drive shaft by the screw drive causes the linear motion of the drive shaft. If the stop or protrusion reaches the end of the linear guide, the rotational motion of the screw drive is no longer converted into a linear motion, but the drive shaft rotates in the direction of the groove that triggers the rotation. Therefore, a linear guide formed along the longitudinal direction of the drive shaft is constructed in the guide element, and a groove arranged around the guide element, wherein the surrounding groove realizes the swinging motion of the drive shaft, and thus the cover. In this respect, the guide element of the screw drive is coordinated with the guide element of the drive device via the control profile. Finally, in this exemplary embodiment, only an alternative drive device is shown for moving the cover.

[0028] In both embodiments, the cover is moved linearly and / or rotationally by means of a motor, a transmission and a guide element. Of course, the movement is not limited to a linear movement and a subsequent swinging movement, but according to the embodiment and the existing space requirements, the swinging movement can also start immediately as the cover is detached from the housing of the charging socket device, so that parallel swinging and linear movements can be introduced into the cover. It has been proven to be advantageous to use a two-stage transmission. It is also conceivable that more than two transmission stages can be used so that a suitable adjustment movement or adjustment speed can be introduced into the cover. For example, it is conceivable that a worm gear is directly arranged on the motor, wherein the worm gear terminates at another transmission stage, and the second transmission stage drives a lead screw nut, for example. Different transmissions can be used according to the space requirements, the force required for moving the cover, the adjustment speed and / or the necessary rotation angle or swinging movement.

[0029] The present invention is described in detail below according to a preferred embodiment with reference to the accompanying drawings. However, the following principle applies, that is, the embodiment does not limit the present invention, but only shows an advantageous design form. The features shown can be implemented alone or in combination with other features of the specification and the claims. The figure shows:

[0036] Figure 7 A three-dimensional view showing an alternative embodiment of a drive device of a spindle drive in the form of a cover,

[0037] Figure 8 Show according to Figure 7 1. View of a spindle drive in FIG. 1, wherein the spindle drive is shown in a position during a pivoting movement of the cover.

[0038] Figure 1 A three-dimensional view of a charging socket device 1 is shown. The charging socket device 1 is partially closed by a cover 2, so that only the first socket 3 is in the open position. The charging socket device 1 is presented separately from the motor vehicle, wherein the charging socket device 1 can usually be arranged in a charging compartment (also not shown) behind a charging cover of the motor vehicle. The charging socket device 1 has a housing 4, wherein two different sockets 3, 5 are arranged in the housing 4. The first socket 3 is preferably a socket for charging with an alternating voltage, while the second socket 5 is suitable for charging with a direct current.

[0039] A plastic drive shaft 6 is preferably integrally formed on the cover 2, and the drive shaft extends from the surface 7 of the housing 4 to the inside of the housing 4. The drive shaft 6 cooperates with the drive wheel 8. For example, the toothed portion of the transmission device meshes with the drive wheel 8, and the transmission device in turn cooperates with the motor, or is driven by the motor. The transmission device and the electric drive device for driving the drive wheel 8 are not shown in this view. The drive shaft 6 has a first control molding 9, which acts together with the drive wheel 8, especially the drive pin 10. In addition, a guide element 11 can be seen, which guides the cover 2 so that it can move linearly and swing. The guide element 11 can be fixedly received in the housing of the charging socket device 1 or the body of the motor vehicle, for example. In any case, the guide element is arranged in the motor vehicle in a fixed position relative to the drive shaft 6.

[0040] If the drive wheel 8 is now acted upon by the force of the motor, the drive wheel 8 moves in the direction of the arrow P, in the present embodiment, in the counterclockwise direction.

[0041] By the movement of the drive wheel (such as Figure 2 ), the drive pin enters the Figure 2 As can be clearly seen from the figure, the rotation angle of the drive wheel 8 is about 80°-120° or about 90°. In this case, the drive pin 10 cooperates with the control molding 9 and moves the drive shaft 6 along the center axis M of the drive shaft 6. The cover 2 performs a lifting movement due to the linear movement of the drive shaft 6, so that the cover 2 is lifted from the surface 7 of the housing 4. As a result, the cover is lifted from Figure 1 The sealing position in Figure 2 When the linearly movable final position is reached, the drive pin 10 abuts against the stop surface 12 on the control profile. Figure 5 It can be seen more clearly in FIG. 1 that the stop 13 moves into the idle region 14 , wherein the idle region 14 is arranged at the end of the linear guide 15 .

[0042] If the drive wheel 8 is further driven in the counterclockwise direction in the direction of arrow P, the stop surface 12 and the drive pin 10 drive the drive shaft in combination, so that the drive shaft 6 also rotates in the counterclockwise direction. Figure 3 In this regard, Figure 3 The final position of the cover 2 after the drive shaft has been rotated by about 120° is shown. As the cover 2 is rotated, the second socket 5 is completely exposed. Now, the operator can use the DC socket 5.

[0043] As the final position of the cover 2 is reached, the locking device 16 engages in the locking molding 17 in the drive shaft 6. The drive wheel 8 is now locked to the drive shaft 6. If the drive wheel 8 is now driven in the clockwise direction in the direction of the arrow P1 starting from the offset position of the cover 2, the drive wheel 8 drives the drive shaft 6, and the cover rotates to its initial position above the second socket 5. As the final position or initial position of the cover 2 is reached and the drive wheel 5 is further driven, the stop 13 contacts the linear guide 15, so that the locking device 16 can be moved out of the locking molding. During further movement in the clockwise direction in the direction of the arrow P1, the drive cam 18 engages in another control molding 19 on the drive shaft 6, so that when the drive wheel 8 is further driven, the drive shaft 6 and therefore the cover 2 move again in the direction of the surface 7 of the housing. At this time, the cover is again in the initial position, in which the cover 2 covers the opening 20 of the socket 5. As shown in FIG. Figure 1 As can be clearly seen, the cover 2 completely covers the opening 20 and has a recess 21 , thereby enabling complete sealing of the charging plug engaged with the first socket 3 .

[0044] exist Figure 5 An enlarged detailed view of the drive shaft 6 and the drive wheel 8 is presented in FIG. The locking means 16 engages with the locking molding 17, from which it can be inferred that the drive shaft 6 is in the end position of the oscillating movement or at least in the rotational stroke of the cover 2. Figure 5 It can be clearly seen in FIG. 1 that the pivoting movement is guided by the idle region 14 or the rotary guide 14. For this purpose, the stop 13 moves through the idle region 14 until the stop 13 abuts against a stop surface 22 in the guide element 11. When the stop surface 22 is reached, the drive cam 18 then engages in the control profile 19 and moves the stop 13 along the linear guide 15, whereby the cover 2 moves along the center axis M, and finally the cover 2 reaches a position in which it is in sealing contact with the surface 7 of the housing.

[0045] Figure 6Another partial view of the axial end 23 of the drive shaft 6 and the drive wheel 8 is shown. It can be seen that the drive pin 10 contacts the stop surface 12 at the end of the control profile 9. The position of the cover 2 can also be inferred from the position of the locking means 16, which is in the raised position and in the open position, i.e., in a position swung away from the opening 20 of the socket 5.

[0046] The design of the charging socket device 1 according to the invention now makes it possible to protect the socket that is not needed during charging and also to enable automatic charging of the motor vehicle in that the cover 2 can be swiveled out of the area of ​​the socket 5 electrically and automatically by means of a control unit.

[0047] Figure 7 An alternative embodiment of a drive for the cover 24 is shown in the form of a spindle drive 25. The electric motor is accommodated in the drive housing and drives a multi-stage transmission 28. The spindle nut 29 is driven by the transmission stages of the transmission 28, wherein the spindle nut acts directly on the drive shaft 30. The drive shaft 30 is in turn connected to the cover 24. In addition, a guide element 31 can be seen, which is operatively connected to the drive shaft 30. A sealing device 32, such as a sealing ring, seals the drive shaft 30, so that the drive housing 27 is protected from external influences. The drive housing 27 can be connected to the housing 4 of the charging socket device, for example, by means of a fixing device 23. The drive housing 27 is preferably made of plastic, and the fixing device 33 can be, for example, a threaded hole, which enables fixing on the charging socket device 1.

[0048] exist Figure 7 In the position of the cover 24 shown, the cover 24 has moved linearly in the direction of the arrow P2. A portion of the thread 34 of the spindle drive 25 can be seen. In other words, the drive shaft 30 has moved in the direction of the arrow P2, so that the cover 24 has been lifted from the surface 6 of the charging socket device 1 in this position.

[0049] exist Figure 8 Another movement of the cover 24 is presented in FIG, in which the cover 24 performs a swinging motion. The spindle nut 29 has been further driven by means of the motor 26, wherein a stop 35 on the drive shaft 30 is guided in a guide element 31. The guide element 31 has a linear guide in which the stop 35 is guided in the direction of the arrow P2. After reaching the end of the linear guide, the stop 35 is no longer prevented from rotating, so that the stop 35 can perform a swinging motion along the idle travel area. Therefore, the stop 35 in combination with the guide element 31 can realize a swinging motion as well as a linear motion of the cover 24. Here, the cover 24 is Figure 8 The drive shaft 30 moves in the direction of the arrow P3 in a pivoting movement about the center axis M of the drive shaft 30 shown in FIG.

[0050] It goes without saying that, for example, a control profile 36 can be provided, by means of which the microswitch can be actuated. However, the control profile can also be used, for example, as an end stop for the linear movement of the drive shaft 30. As an adjustment movement in the direction of the arrow P2, a movement in the range of 2 mm to 12 mm, preferably 3 mm to 10 mm, can be realized. As described above, a swivel movement in an angular range of 80° to 150°, preferably 90° to 120°, can be set or realized. The angle to be set can be set by means of the stop 3, 35 or by means of the control profile 9, 19, 36 and / or by means of other stops, for example on the cover 2, 24.
