Definitions
- the invention relates to an electromotive locking unit for an electric charging device of a motor vehicle, in particular an electric or hybrid motor vehicle, with an electric motor and a subsequent transmission, furthermore with a locking element that can be acted upon linearly by the gear for releasably locking a charging plug in a charging socket of the electrical charging device, and with at least a stop for the locking element.
- a charging infrastructure is generally used for this purpose, which typically includes charging stations that are equipped with a charging plug connected to an extension cable.
- the charging plug of the charging station is generally coupled and releasably locked to the charging socket on the motor vehicle. This is ensured by the locking element moved by an electric motor.
- the interlock is necessary to avoid health hazards, for example, since high voltage is generally used at this point.
- the locking also ensures that only previously identified users lawfully draw the electrical energy provided by the charging station and misuse is prevented.
- an identification of the operator and an authorization check with the help of an identification signal usually takes place before such a loading process. This is described in principle and by way of example in WO 2010/149426 A1.
- the locking element is adjusted in the prior art according to CN 2020695855 U with the aid of an electric motor drive, which consists of an electric motor and a downstream multi-stage gearbox assembled.
- the multi-stage gearing works via a cam on the locking element, which can be acted upon in a linear manner as a result.
- DE 10 2013 008 550 A1 deals with an electromechanical locking unit for the vehicle sector.
- this has a mechanical stop assigned to the locking mechanism, which blocks its movement at a defined end position.
- the stop has an elastic element which is arranged in such a way that it is mechanically deformed before the defined end position is reached. In this way, the movement of a movement element, in particular the locking element, is delayed.
- a locking device for locking an electrical plug in a socket is described.
- the locking device in question can also be used in connection with an electric charging device in electric or hybrid motor vehicles.
- a locking bolt realized at this point is equipped with stops that interact with driver stops on a driver element.
- the driver stops and counter-stops are obviously not elastic, so that the well-known locking bolt runs against hard end stops.
- the invention is based on the technical problem of further developing such an electromotive locking unit for an electric charging device of a motor vehicle in such a way that there is perfect functionality and, in particular, damage to the locking element in the area of its stops is reliably avoided.
- a generic electromotive locking unit within the scope of the invention is characterized in that the stop for the locking element is designed as an elastic end stop buffer which is held in a recess in the locking element.
- a special stop is used as a stop for the locking element, namely an elastic end stop buffer which, due to its elasticity, absorbs and dampens stress peaks from the outset when the stop or end stop for the locking element is approached.
- the end stop buffer Due to the additional attachment of the end stop buffer in a recess of the locking element, the end stop buffer can also be equipped with a significant size that is sufficient for the desired functionality and consequently with a damping effect.
- the attachment of the end stop buffer in the recess of the locking element opens up the further advantage that the overall height in a housing accommodating the electromotive locking unit can be kept low and is not negatively influenced by the provided end stop buffer.
- the recess is typically connected to the locking element via a cantilever, preferably on the head side, also contributes to this.
- the recess can be placed “next to” the locking element, for example, in a free area already observed inside the housing for accommodating the electromotive locking unit.
- This favors a compact design and at the same time offers the possibility of making the end stop buffer projecting and of the desired size in order to provide a significant damping path in the area of the end stop of the locking element.
- the end stop buffer is generally made of an elastomer, ie an elastomeric plastic, also contributes to this.
- elastomers such as acrylate rubber (ACM), acrylonitrile butadiene rubber (NBR), ethylene propylene rubber (EPDM), natural rubber (NR), styrene butadiene rubber (SBR) can be used come, just to name an example of individual suitable elastomers or elastomeric plastics.
- ACM acrylate rubber
- NBR acrylonitrile butadiene rubber
- EPDM ethylene propylene rubber
- NR natural rubber
- SBR styrene butadiene rubber
- the locking element is also made of a (thermoplastic) plastic and the recess, including the arm, generally defines a one-piece component together with the locking element, the locking element or the recess and the one in the recess can recorded end stop buffers are always manufactured as a one-piece component.
- the end stop buffer made of the elastomeric plastic may be molded onto the thermoplastic plastic of the recess, for example, or may be produced together with this in a two-component injection molding process.
- the locking element including the recess and extension is a separate (thermoplastic) component made of plastic, which is detachably coupled to the separate end stop buffer made of the elastomer or elastomeric plastic.
- the procedure is usually such that the end stop buffer is detachably connected to a web in the recess.
- the web can divide the recess approximately in half.
- a horizontal division of the recess is usually observed here.
- the bridge regularly has a receiving slot.
- the receiving slot is usually designed to run in the direction of assembly of the end stop buffer.
- a V-shaped tapered receiving slit is usually observed here.
- two end stop buffers located opposite one another in relation to the web are advantageously implemented.
- the two end stop buffers interact on the one hand with a counter stop in a housing and on the other hand with another counter stop in a cover for the housing.
- the overall design is such that the electromotive locking unit is accommodated in its entirety in the housing, with the housing being closed at the head with the aid of the cover.
- the electromotive locking unit can define a component part of the electric charging device as a structural unit or module. In fact, this is a key ingredient.
- the design is also such that the locking element, which can be retracted and extended relative to the housing, can more or less protrude through a seal from the housing in question and can be withdrawn again.
- the two end stop buffers are generally of the same design and usually have a ring-shaped character, comparable to a "donut".
- the two end stop buffers are regularly coupled to one another with the aid of a connecting web. The connecting web generally engages in the receiving slot of the web dividing the recess approximately in half.
- the end stop buffer Due to the ring-shaped shape of the end stop buffer with a central recess, which is followed by the connecting web coupling the two end stop buffers, a particularly favorable damping behavior is observed, which is also able to accommodate large damping paths. Because the annular character of the end stop buffer not only allows an intramolecular deformation of the end stop buffer made of the elastomer, but the end stop buffer can also deform spatially or macromolecularly or with regard to its external shape, for example it can be almost "pressed flat". This is because the central recess of the ring-shaped end stop buffer allows material to escape into the recess when it is compressed.
- an electromotive locking unit for an electric charging device of a motor vehicle is made available overall, which offers both functional and acoustic advantages. Because of the special end stop buffer, the locking element is prevented from running “hard” against the respective counter stop interacting with the end stop buffer in the housing or in the cover at the end of its travel. Rather, the interposed end stop buffer ensures a soft impact at the end of the travel path and thereby avoids any stress peaks introduced into the material (made of plastic). This significantly increases the service life and functionality of the locking element.
- the soft start-up in the area of the respective counter-stops is acoustically optimized and thus the noise development could be reduced to a minimum compared to the state of the art.
- the attachment of the end stop buffer in the recess via the cantilever ensures that the overall height of the locking element does not increase, but rather the recess together with the end stop buffer as it were “next” to the locking element in a cavity of the housing.
- the compact structure of the electromotive locking unit according to the invention is not adversely affected compared to previous embodiments. This is where the main advantages can be seen.
- FIG. 1 schematically shows the electromotive locking unit according to the invention together with the electric charging device
- Fig. 2 shows the electromotive locking unit in a general overview
- FIG. 3 shows a detail from FIG. 2 in the area of the locking element.
- FIG. 1 shows an electromotive locking unit for an electric charging device of a motor vehicle.
- the electromotive locking unit is accommodated in a housing 1, which is the subject of FIG. 2 in the open state.
- the housing 1 is closed with a cover 2, which is not expressly shown in FIG. 2, and is usually hermetically sealed. Inside the housing 1 you can see an electric motor 3, which works on a subsequent gear 4, 5.
- the transmission 4 , 5 consists essentially of a gear wheel 4 meshing with a worm on the output shaft of the electric motor 3 on the one hand and a crank wheel 5 on the other hand, which interacts with a locking element 6 .
- the crank wheel 5 engages with a crank pin in a corresponding pin receptacle of the locking element 6 and in this way ensures that the locking element 6 can perform linear movements in the linear direction L shown in FIG. 1 in particular.
- the locking element 6 emerges more or less from the housing 1 in the region of a recess shown, the recess being closed with the aid of a seal through which the locking element 6 passes.
- the locking element 6 moves into a recess of a charging module 7, so that in this way a charging plug 8 of the charging station infrastructure already described in the introduction can be releasably locked to a charging socket 9 on the motor vehicle.
- the electromotive locking unit or the locking actuator realized in this way with the housing 1 including the cover 2 and the locking element 6 which can be moved in relation thereto is the main component of the electric charging device 1, 2, 6; 7, 9.
- FIG. 7 now shows the internal structure of the electromotive locking unit inside the housing 1 with the cover 2 removed.
- the locking element 6 which can be moved in the linear direction L as shown in FIG. 7, 9 lock.
- a stop 10 associated with the locking element 6 can also be seen.
- the stop 10 of the locking element 6 interacts with an associated counter-stop 11 at the end of the travel path of the locking element 6 in the linear direction L.
- FIG. 3 shows that a counter-stop 11 is provided inside the housing 1 .
- Another counter-stop 1 1 is found on the other hand inside the cover 2 and is indicated in FIG.
- the locking element 6 can be moved back and forth with its stop 10 in the linear direction L between the two counter-stops 11. As a result, the travel of the locking element 6 is specified and limited.
- end stop buffer 10 is formed, which is held in a recess 12 of the locking element 6.
- the recess 12 is connected to the locking element 6 via a cantilever 13 . That is, the recess 12 moves together with the locking element 6 also in the linear direction L, as indicated in Fig. 3, but at a distance from a pin-shaped extension 6a of the locking element 6, which is ultimately responsible for the releasable locking of the Charging plug 8 in the charging socket 9 provides.
- the recess 12 accommodating the end stop buffer 10 is located on the locking element 6 inside the housing 1, specifically in a cavity which is defined and specified by the gear wheel 4 on the one hand and the crank wheel 5 on the other hand.
- its movement in the linear direction L is limited with the aid of the end stop buffer 10 of the locking element 6, specifically without the housing 1 thereby having an increasing structural height.
- the locking element 6 including the extension arm 13 and the recess 12 as a whole define a one-piece component made of a thermoplastic material in the example.
- the stop buffer 10 is a separate component made of an elastomeric plastic.
- the end stop buffer 10 To mount the end stop buffer 10, it is detachably connected to a web 14 in the recess 12.
- the web 14 ensures that the recess 12, which is U-shaped in plan view, is divided approximately in half.
- the web 14 is equipped with a receiving slot 15 tapering in a mounting direction M of the end stop buffer 10 .
- the receiving slot 15 is designed tapering in a V-shape in the mounting direction M in question.
- two opposite end stop buffers 10 are realized in relation to the web 14, which runs mostly horizontally.
- the two end stop buffers 10 interact on the one hand with the counter stop 11 in the housing 1 and on the other hand with the further counter stop 11 in the cover 2 for the housing 1 indicated in FIG.
- the two end stop buffers 10 are designed the same overall and engage in the receiving slot 15 with the aid of a connecting web 10a that couples them of the bridge 14.
- the connecting web 10a between the two end stop buffers 10 extends in each case starting from a recess 10b in the associated end stop buffer 10.
- the respective end stop buffer 10 according to the exemplary embodiment is ring-shaped in the manner of a “donut”. This results in the previously mentioned recess 10b in its center, which continues in the connecting web 10a to the other second end stop buffer 10.
- the cutout 10b enables large damping paths of the end stop buffer 10, because it can deviate into the cutout 10b when it is deformed and can thus be almost “pressed flat”.
