Description

[0001] Description Charging socket for an electric or hybrid vehicle The invention relates to a charging socket for an electric or hybrid vehicle comprising a first multi-pin socket, a second two-pin socket, wherein the sockets form the charging socket and are arranged together in a charging recess of a motor vehicle body, and a movable charging flap, wherein the charging recess can be covered by means of the charging flap. Such charging sockets are preferably integrated in the body of motor vehicles and are usually arranged in a protected manner behind a movably arranged charging flap. The charging flap serves, on the one hand, to prevent misuse of the charging socket and, on the other hand,to protect the charging socket from environmental influences. The charging socket is used in different design variants. The invention relates to a charging socket with a first socket for an alternating voltage and a second socket for a direct voltage connection. The sockets differ in the number of available poles and essentially in the fact that different charging currents are available for the motor vehicle. The charging socket according to the invention has a combination of a multi-pole and a two-pole socket. Such sockets are also referred to as Type 2 plugs for DC and AC charging and are known as EU standard plugs. The charging socket is permanently arranged in a charging recess of a motor vehicle so that an operator is able toInsert the charging plug into the charging socket of the charging recess. Various prior art solutions have become known for closing the charging recess and thus covering the charging socket. DE 202021 901 685 U1 discloses a sliding and pivoting device for a vehicle lid to cover a charging socket. To release the charging socket, which is also referred to here as an interface or charging module, the vehicle lid can first be moved using a sliding device and then moved using a pivoting device. The charging socket is thus released via a linear displacement followed by pivoting of the vehicle lid. DE 10 2020 209 607 A1 discloses a closure arrangement for closing a fuel tank recess of a motor vehicle body.wherein a cover element is displaceably moved within the body by means of a linear drive. The closure arrangement performs two different movements. To open the charging recess, the charging flap or cover element is first moved by means of a lifting movement, in order to then perform a longitudinal movement and thus release the charging socket. From the unpublished DE 10 2021 116 318.8, a device for closing a charging device of an electric or hybrid vehicle has become known, comprising a connector half arranged in the vehicle, for connection to another connector half, an electrically driven closure device, wherein, in an unactuated state of the connector half, an opening of the charging device can be closed by means of the closure device.and wherein the locking device is mechanically engageable with the further connector half inserted into the connector half, wherein a position of the locking device is detectable by means of a sensor. In two different exemplary embodiments, it is described that the charging flap is arranged displaceably, so that the charging socket or the charging recess can be closed at least partially even during the charging process. The solutions known from the prior art have generally proven themselves. However, the prior art reaches its limits when it comes to protecting the unused socket. This is especially true when charging must take place under weather and / or environmental influences.When charging via one socket, the other socket can only be protected to a limited extent from environmental influences and misuse. This is where the invention comes in and aims to demonstrate improvements. The object of the invention is to provide an improved charging socket for an electric or hybrid vehicle. In particular, the object of the invention is to create protection for an unused socket so that overall safe operation of the charging process can be guaranteed. The object is achieved according to the invention by the features of independent patent claim 1. Advantageous embodiments are specified in the subclaims. However, it is pointed out that the exemplary embodiments described below are not restrictive; rather, any possible variations of the embodiments described in the description,The features described in the patent claims and the drawings are possible. According to patent claim 1, the object of the invention is achieved by providing a charging socket for an electric or hybrid vehicle, comprising a first multi-pin socket, a second two-pin socket, wherein the sockets form the charging socket and are arranged together in a charging recess of a motor vehicle body, and a movable charging flap, wherein the charging recess can be covered by means of the charging flap, and wherein one socket, preferably the second two-pin socket, can be closed separately. The inventive design of the charging socket now creates the possibility of partially closing the charging socket, so that one socket can be kept closed during charging. This offers a multitude of advantages,which are described in more detail below in the respective embodiments. A significant advantage of the charging socket design according to the invention is that the second socket not used for charging is closed during the charging process. This protects the unused socket from environmental influences and, moreover, from improper or misuse. For example, in the case of humidity or precipitation in the form of rain or snow, no moisture can penetrate the other socket. The charging flap usually covers and / or seals the charging recess.However, if a charging plug is inserted, the charging recess may not be closed or may only be partially closed. The inventive use of a separate cover for the socket not assigned to the charging process ensures secure and complete closure of the additional socket, thus protecting the additional socket during the charging process. A charging socket according to the invention is used in motor vehicles, such as passenger cars, vans, industrial trucks, trucks, etc. This list is, of course, not limiting; rather, the charging socket can be used wherever electric or hybrid-powered vehicles or means of transport equipped with a traction battery are used. Driverless transport vehicles, such as buses, work equipment, etc., are also suitable.are included. As already explained above, the charging socket has two sockets, one of which can be used for charging with an alternating current (AC) and a second socket that can be supplied with a direct current (DC). Such sockets are known and, for example, certified by EU standards. The sockets are arranged next to each other in a charging recess. This offers the advantage that a charging flap can close the charging recess, so that the passenger vehicle, for example, can form a flat surface with the charging flap. The term charging recess is not to be understood as restrictive, but can also include another opening or a loading space of the vehicle. For example, if the charging socket is installed in the trunk of a vehicle,In this case, the loading recess would be designed as a trunk, and the loading flap would be formed by the trunk lid. It is essential to the invention that at least one socket, preferably the second DC socket, can be closed separately. If the second socket can be closed or covered by a cover flap, this results in an advantageous embodiment of the invention. Closing the additional socket with a cover flap offers the advantage of enabling a sealed closure of the socket. The cover flap can fit completely around the socket and thus prevent the penetration of environmental influences. The cover flap can follow the shape of the socket and thus ensure protection for the socket with the smallest possible design. The cover flap serves as protection,so that the cover flap can also be referred to as a protective cap or protective flap or cover cap. The function of the cover flap is to seal the socket on its outer circumference. The cover flap is advantageously made of a plastic. Plastics have the advantage of being lightweight, easy to form into any shape, and, moreover, as a cost-effective material, have a positive effect on the cost of the charging socket. It is also conceivable for the cover flap to have a seal, whereby the seal can be formed all the way around one edge of the socket. The seal can be mounted in one piece on the cover flap or formed as an integral part of the cover flap. In this case, the cover flap would, for example, be formed as a two-component component. If the second socket can be closed in this way,that a charging plug can be inserted into the first socket, this again results in an advantageous embodiment of the invention. The cover flap closes the socket in such a way that the first socket is freely accessible and can function as a socket. Consequently, charging via the first socket is possible, wherein the charging flap is preferably designed in such a way that it follows the shape of the opening of the first socket. The first socket is thus completely enclosed by the housing of the charging socket and the cover flap, so that a completely open first socket is available to the operator. In other words, the cover flap follows the shape of the opening of the first socket. This offers the advantagethat a plug inserted into the first socket is sealed all the way around. Thus, neither dirt nor moisture can penetrate into the second socket nor the first socket during the charging process. In a further embodiment of the invention, the cover flap is electrically actuated. The cover flap is moved by means of an electric drive, and preferably by means of an electric drive and at least one gear stage. Electrical energy is available in the motor vehicle,so that a movement can be introduced into the cover flap by means of a microdrive. The cover flap can be moved in a linear pivoting motion or in a combined movement, for example, of linear movement and pivoting movement. Depending on the arrangement of the cover flap, the cover flap is then moved over the preferably second socket and ultimately brought into sealing contact with an opening of the second socket. A further embodiment of the invention arises when the cover flap can be lifted from the second socket by means of a lifting movement and moved out of an overlap area with the second socket by means of a second pivoting movement. The combined movement of a lifting movement and a pivoting movement makes it possible to achieve the best possible fit of the cover flap over the opening of the second socket. The cover flap covers the opening of the second socket in such a way thatthat a sealing cover can be realized. According to the invention, it is also conceivable that the cover flap fits positively into the opening of the second socket, so that the cover flap is flush with a housing of the charging socket. It is also conceivable that, for example, a circumferential recess is arranged in the housing of the charging socket, into which the cover flap can be inserted. Due to the first lifting movement, the cover flap is then able to detach itself from the system with the housing of the charging socket and then reach an area in which the cover flap can be pivoted. A pivoting movement can be an angle of more than 90°, preferably 120°.so that the cover flap can be pivoted completely out of the area of ​​the socket openings. In the case of a linear movement and / or a pivoting movement and / or a folding movement of the cover flap, the cover flap is always moved far enough so that the second socket is freely accessible. In an advantageous design variant of the invention, the cover flap is connected to a drive shaft, wherein the drive shaft is actuated by means of a drive wheel. The drive shaft is preferably arranged at a lateral end of the cover flap, so that a pivoting movement of the cover flap allows the cover flap to be pivoted out of the area of ​​the socket openings. By using a drive shaft, it is possible to arrange the electrical drive at a distance from the socket area.so that a structurally advantageous and space-saving arrangement of the electric drive is possible. A drive wheel works together with the drive shaft, whereby the drive wheel engages via an electric motor and a downstream gear. The drive wheel enables the movement of the drive shaft in the axial direction as well as 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 an area behind the socket. If the drive shaft has a control contour and the cover flap can be moved linearly by means of the control contour and a linear guide, a safe, fast, and precise movement of the cover flap can be achieved. The drive shaft and drive wheel work together in such a way thatthat a linear movement of the drive shaft can be realized by means of the control contour attached to the drive shaft. The drive wheel can engage the control contour in such a way that the drive shaft can be displaced along its central axis. For this purpose, the drive shaft is pivotally and linearly displaceably mounted in a linear guide in a housing. In continuation of the inventive concept, the drive shaft has at least one stop and the linear guide has a freewheel area, wherein a pivoting movement of the loading flap can be limited and guided by means of the stop. In connection with the exemplary embodiment, the drive shaft can also be referred to as a control shaft in cooperation with the linear guide. A stop and guide means are provided on the drive shaft.which can be guided through the linear guide in a linear movement. After the cover flap is raised, the stop reaches a stop point in the linear guide, preventing further linear displacement. At the same time, the stop reaches a freewheeling area through which the drive shaft can be pivoted. The linear guide thus also serves as a guide for the pivoting movement. This pivoting movement is realized by the drive wheel continuing to be driven and the drive wheel reaching a stop surface on the control contour of the drive shaft, by means of which the drive shaft can be pivoted. If the drive shaft is moved linearly via the control contour of the drive shaft, a pivoting movement can be initiated in the drive shaft simultaneously by means of the drive wheel. Drive wheel,The drive shaft and the guide in the housing thus enable a lifting movement of the cover flap as well as a pivoting of the cover flap out of the opening area of ​​the sockets. In a further embodiment of the invention, the drive wheel has at least one further stop and / or at least one locking means, so that a closing movement of the cover flap can be realized by means of the drive wheel. The drive wheel can, for example, move the cover flap back to its original position by means of a backward movement. For this purpose, the drive wheel has a locking means or interacts with the locking means in such a way that when the end position of the cover flap is reached, i.e., in the fully pivoted position, the locking means engages a contour of the drive shaft. If the drive wheel is now moved back by means of the electric drive,The pivoting movement of the cover flap can be pivoted until it reaches an end position in the linear guide or the pivoting guide. Upon reaching the linear part of the linear guide, the locking means disengages, and the drive wheel can be moved linearly back to its starting position via another control cam on the drive shaft. The cover flap then closes the socket again. The inventive design of the charging socket creates the possibility of protecting the sockets even during the charging process, thus enabling safe and long-term use of the charging socket. In a further embodiment of the invention, the drive wheel is designed as part of a spindle drive. A spindle drive offers the advantage ofthat very smooth and precise linear movements can be generated. Spindle drives also exhibit a high degree of smoothness and thus enable continuous movement of the drive shaft. An actuating movement of the cover flap can thus be realized with the simplest design means and in a very small construction. A very small drive and thus a structurally advantageous design is particularly achieved when the drive shaft is designed as a spindle nut and the drive wheel as a spindle. The drive shaft thus functions directly as a gear component, whereby the smallest possible number of components is necessary to provide a linear drive. In addition, by designing the drive shaft as a spindle nut, a very precise and smooth movement of the cover flap can be realized. In addition, large actuating forces can be realized using a spindle drive, so that even weather influences,such as frost, and thus the adhesion of the cover flap, can be overcome. The drive shaft itself is movable by means of a guide element, in particular linearly and rotationally. The drive shaft can be guided linearly and rotationally by means of a guide element, just as in the first embodiment. For this purpose, the guide element has a linear groove within which the drive shaft can be moved linearly, and at least one further groove by means of which a rotational movement of the drive shaft can be guided. The guide element thus determines the movement sequence of the drive shaft and thus the position of the cover flap, which is connected to the drive shaft in such a way that the cover flap follows the movement of the drive shaft. The movement of the drive shaft can be realized by means of a guide means. The drive shaft has a guide means, in particular a stop,The drive shaft is movable in the guide element by means of the guide means. The movement is introduced into the drive shaft by means of the spindle drive. The guide means is part of the guide element or interacts with the guide element. The guide means can be designed, for example, as a groove or elevation and interacts with the guide element such that the drive shaft executes a linear and / or pivoting movement. For this purpose, a stop can be formed on the drive shaft as a guide means, for example, so that the stop forms an elevation on the drive shaft. The stop itself is then guided in the guide element, for example, a linear groove, so that the movement introduced into the drive shaft by the spindle drive results in a linear movement of the drive shaft. If the stop or elevation reaches the end of the linear guide,Thus, the rotary motion of the spindle drive is no longer converted into a linear motion, but the drive shaft rotates in the direction of the groove that enables rotation. Consequently, the guide element incorporates a linear guide formed in the longitudinal direction of the drive shaft and a groove arranged circumferentially in the guide element, with the circumferential groove implementing a rotational movement of the drive shaft and thus of the cover flap. In this respect, the guide element of the spindle drive coincides with the guide element of the drive via the control cam. Ultimately, only an alternative drive for moving the cover flap is shown in this embodiment. In both embodiments, the cover flap is moved linearly and / or rotationally by means of an electric motor, a gear, and the guide element. The movement is, of course, not limited to a linear followed by a rotational movement.But depending on the design and the available space requirements, a rotational movement can also begin immediately upon detaching the cover flap from the charging socket housing, so that a parallel rotary and linear movement can be introduced into the cover flap. The use of a two-stage gear mechanism has proven advantageous in this case. It is also conceivable that more than two gear stages can be used in order to be able to introduce suitable actuating movements or actuating speeds into the cover flap. For example, it is conceivable that a worm drive is provided directly on the electric motor, with the worm drive ending in a further gear stage, and the second gear stage driving, for example, the spindle nut. Depending on the space requirements, the force required to move the cover flap,Different gears can be used depending on the setting speed and / or the required swivel angle or swivel movement. The invention is explained in more detail below with reference to the accompanying drawings using a preferred embodiment. However, the principle applies that the embodiment does not limit the invention, but merely represents an advantageous embodiment. The features shown can be implemented individually or in combination with further features of the description as well as the patent claims. It shows: Figure 1 is a three-dimensional view of a charging socket designed according to the invention, with the cover flap shown in a closed position. Figure 2 is the charging socket shown according to the invention in Figure 1, with the cover flap shown in a position lifted from the second socket.Figure 3 shows the charging socket according to the invention, wherein the cover flap is shown in a fully pivoted position, Figure 4 shows a detailed view of the drive shaft and the drive wheel in a position in which the cover flap is fully pivoted, Figure 5 shows a detailed view of the linear guide in engagement with the drive shaft, Figure 6 shows a detailed view of the drive wheel and one end of the drive shaft in a position in which the cover flap is in the fully pivoted position, Figure 7 shows a three-dimensional view of an alternative embodiment of a drive for the cover flap in the form of a spindle drive, and Figure 8 shows a view of the spindle drive according to Figure 7,The spindle drive is shown in a position during the pivoting movement of the cover flap. Figure 1 shows a three-dimensional view of a charging socket 1. The charging socket 1 is partially closed by a cover flap 2, so that only a first socket 3 is in an open position. The charging socket 1 is shown detached from a motor vehicle, wherein the charging socket 1 can usually be arranged behind a charging flap of a motor vehicle in a charging recess (again not shown). The charging socket 1 has a housing 4, wherein the housing 4 contains two different sockets 3, 5. The first socket 3 is preferably a socket for charging using an alternating voltage.whereas the second socket 5 is suitable for charging via direct current. A drive shaft 6, preferably in one piece and made of plastic, is attached to the cover flap 2 and extends from a surface 7 of the housing 4 toward the housing 4. The drive shaft 6 cooperates with a drive wheel 8. The drive wheel 6 is engaged, for example, by a gearing of a transmission, which in turn cooperates with an electric motor or is driven by an electric motor. The transmission for driving the drive wheel 8 and the electric drive are not shown in this illustration. The drive shaft 6 has a first control contour 9,which interacts with the drive wheel 8 and in particular a drive pin 10. Also visible is a guide element 11 for the linear and pivotal guidance of the cover flap 2. The guide element 11 can, for example, be fixedly received in a housing of the charging socket 1 or a body of the motor vehicle. In any case, the guide element is arranged stationary with respect to the drive shaft 6 in the motor vehicle. If the drive wheel 8 is now acted upon by a force from an electric motor, the drive wheel 8 moves in the direction of arrow P, in the present embodiment counterclockwise. Due to the movement of the drive wheel, as shown in Figure 2, the drive pin reaches the pivoted position shown in Figure 2. As can be clearly seen from the figures,This involves a pivoting angle of the drive wheel 8 of approximately 80-120° or approximately 90°. The drive pin 10 interacts with the control contour 9 and moves the drive shaft 6 along a central axis M of the drive shaft 6. The linear displacement of the drive shaft 6 causes the cover flap 2 to undergo a lifting movement, so that the cover flap 2 lifts off the surface 7 of the housing 4. As a result, the cover flap moves from the sealing system in Figure 1 to the lifted position in Figure 2. When the linearly movable end position is reached, the drive pin 10 comes into contact with a stop surface 12 on the control contour. At the same time, and this can be seen more clearly in Figure 5, a stop 13 is moved into a freewheel area 14, wherein the freewheel area 14 is arranged at one end of a linear guide 15. If the drive wheel 8 is now driven further counterclockwise in the direction of arrow P,The stop surface 12, in combination with the drive pin 10, takes the drive shaft with it and also pivots the drive shaft 6 counterclockwise. The resulting pivoting movement of the cover flap 2 is shown in its final position in Figure 3. Figure 3 shows the end position of the cover flap 2 after pivoting the drive shaft by approximately 120°. When the cover flap 2 pivots, the second socket 5 is completely exposed. The operator is now able to use the DC socket 5 as well. When the cover flap 2 reaches its end position, a locking means 16 engages a locking contour 17 in the drive shaft 6. The drive wheel 8 is now locked to the drive shaft 6. If, starting from this deflected position of the cover flap 2, the drive wheel 8 is driven clockwise in the direction of arrow P1,The drive wheel 8 then takes the drive shaft 6 with it and pivots the cover flap back to its starting position above the second socket 5. Upon reaching the end position or starting position of the cover flap 2 and further driving of the drive wheel 5, the stop 13 comes into contact with the linear guide 15, so that the locking means 16 can be moved out of the locking contour. In a further clockwise movement in the direction of arrow P1, a drive cam 18 engages another control contour 19 on the drive shaft 6, so that upon further driving of the drive wheel 8, the drive shaft 6 and thus the cover flap 2 are moved back towards the surface 7 of the housing. The cover flap is now back in its starting position, in which the cover flap 2 covers the opening 20 of the socket 5. As can be clearly seen in Figure 1,The cover flap 2 completely covers the opening 20, and the cover flap 2 has a recess 21, allowing complete sealing of a charging plug in engagement with the first socket 3. Figure 5 shows an enlarged detailed view of the drive shaft 3 and the drive wheel 8. The locking means 16 is in engagement with the locking contour 17, from which it can be concluded that the drive shaft 6 is in the end position of the pivoting movement or at least on the way to pivoting the cover flap 2 back. As can be clearly seen in Figure 5, the pivoting movement is guided by the freewheel area 14 or a pivot guide 14. For this purpose, the stop 13 moves through the freewheel area 14,until the stop 13 comes against a stop surface 22 in the guide element 11. When the stop surface 22 is reached, the drive cam 18 then engages the control contour 19 and moves the stop 13 along the linear guide 15, which results in the cover flap moving along the central axis M and the cover flap 2 coming into sealing contact with the surface 7 of the housing. Figure 6 shows a further detailed view of an axial end 23 of the drive shaft 6 and the drive wheel 8. The drive bolt 10 can be seen in contact with the stop surface 12 at the end of the control contour 9. The position of the cover flap 2, which is in the raised position and in an open position, i.e. pivoted away from the opening 20 of the socket 5, can again be seen from the position of the locking means 16. The inventive design of the charging socket 1 now creates the possibilityto provide protection for the unused socket during charging and, in addition, to enable automated charging of a motor vehicle by allowing the cover flap 2 to be pivoted out of the area of ​​the socket 5 by an electric motor and by means of a control system. Figure 7 shows an alternative drive form for the cover flap 24 in the form of a spindle drive 25. An electric motor is accommodated in a drive housing and drives a multi-stage gear 28. A spindle nut 29 is driven via the gear stages of the gear 28, with the spindle nut acting directly on the drive shaft 30. The drive shaft 30, in turn, is connected to the cover flap 24. Also visible is a guide element 31, which is operatively connected to the drive shaft 30. A sealing means 32, for example a sealing ring, seals the drive shaft 30.so that the drive housing 27 is protected against external influences. The drive housing 27 can be connected, for example, via fastening means 23 to the housing 4 of the charging socket. The drive housing 27 is preferably made of plastic, and the fastening means 33 can, for example, represent screw openings that enable attachment to the charging socket 1. Figure 7 shows the position assumed by the cover flap 24 in which the cover flap 24 has been moved linearly in the direction of arrow P2. A portion of the thread 34 of the spindle drive 25 can be seen. In other words, the drive shaft 30 has already been moved in the direction of arrow P2, so that the cover flap 24 is already lifted off the surface 6 of the charging socket 1 in this position. Figure 8 shows a further movement of the cover flap 24.whereby the cover flap 24 performs a pivoting movement. The spindle nut 29 is further driven by the electric motor 26, whereby a stop 35 on the drive shaft 30 is guided in the 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 rotary movement along a freewheeling area. The stop 35 in combination with the guide element 31 thus enables a linear movement as well as a pivoting movement of the cover flap 24. In the rotational movement shown in Figure 8, the cover flap 24 is moved around a central axis M of the drive shaft 30 in the direction of the arrow P3. It is understood that, for example, a control contour 36 may be present,by means of which a microswitch can be actuated. The control contour can also serve as an end stop, for example, for a linear movement of the drive shaft 30. Adjustment movements in the direction of arrow P2 can be realized in the range between 2 mm and 12 mm, preferably between 3 and 10 mm. Swivel movements are, as described above, adjustable or realizable between an angle of 80-150°, preferably between 90° and 120°. The angles to be adjusted can be adjusted using the stop 3, 35 or using the control contour 9, 19, 36 and / or using additional stops, for example, on the cover flap 2, 24.
