Description

The invention relates to a door handle, in particular of a vehicle, with a gripping part to be gripped by the user, wherein the gripping part has a cavity in which at least one functional part is arranged, on which at least one electronic component is arranged, wherein the electronic component is encapsulated with a potting compound. In addition, the invention relates to a functional part for a door handle and to a method for introducing a potting compound in a door handle.

In the DE 10 2008 058 341 discloses a motor vehicle door handle having a handle portion comprising a cavity in the interior, in which at least one functional part is arranged with an electronic component. Here, a potting compound is introduced into the cavity for fixing the electronic component and for sealing. It has been shown that in some cases of use of the door handle weight savings are necessary, which can reduce the cost of a door handle.

The object of the present invention is to prevent the above-mentioned disadvantages, in particular to provide a door handle, which has a good functionality and can be produced with a low production cost.

The object of the present invention is achieved by all features of independent claims 1, 17 and 19. In the associated dependent claims preferred embodiments are shown.

For this purpose, the invention provides that the functional part is designed such that within the cavity at least two separate spaces are formed, wherein in a first space, the encapsulated with the potting electronic component is located and the cavity has a second space, which is executed Vergussmassenfrei. An essential core of the invention is that a first space is provided within the handle portion in which the electronic component is located. Since the electronic components always decrease in size, the first space within the cavity of the handle part can only have a small volume. By contrast, the second space can have a larger, casting mass-free volume, wherein the geometry of the functional part ensures that no potting compound from the first room gets into the second room. In this simple way, a weight-reduced door handle can be created. The electronic component is completely protected by the potting compound from external influences. Another advantage is seen in terms of a crash barrier that acts on the door handle. A crash barrier is for example in the DE 10 2008 053 877.9 . DE 10 2009 045 843 . DE 10 2010 037 070 described. Known manner provides a crash barrier in the event of an accident that the door handle does not move out of the door due to its inertia, which would be connected to an unwanted opening of the door. Since the door handle now has a lower mass according to the present invention, the weight for the mass balance at the crash barrier can be adjusted accordingly, in particular be reduced accordingly, whereby the weight saving in the handle is connected simultaneously with a weight saving at the crash barrier. Thus, the total weight saving can be "doubled".

According to the invention, it can be provided that the functional part has a carrier on which the electronic component is arranged, and a channel through which the potting compound can be brought into the first space. For example, the carrier may include fastening aids to easily and inexpensively secure the electronics component to the functional part before the functional part is brought into the cavity. For example, the carrier may have latching elements, clip elements, corresponding surfaces or recesses which are adapted to the shape of the electronic component, so that a simple attachment of the electronic component to the carrier can be realized. Here, the electronic component can be positively and / or positively and / or materially secured to the carrier. For example, the electronic component may be clipped to the carrier. Also, an adhesive bond between the electronic component and the carrier is possible. Likewise, the electronic component can be welded to the carrier, in particular laser-welded.

In a further conceivable embodiment of the invention, the functional part can have a separating element which is located between the first space and the second space, wherein in particular the separating element seals the two spaces from each other in such a way that the casting compound remains only within the first space. So that the second, casting compound-free space is sealed from the first room, the separator can ensure that only the potting compound remains in the first room.

The design of the functional part with a channel has the advantage that without any additional parts, the filling of the handle part can be done with the potting compound on the functional part, wherein the potting compound is conveyed through the channel in the direction of the first room. The channel may extend depending on the geometric shape of the functional part, the door handle and / or the handle part by the Vergussmassenfreien second space without the risk that the potting compound enters this second space.

In a measure improving the invention it can be provided that the carrier and / or the channel are arranged on the separating element, in particular that the separating element forms a common component, in particular a monolithic component, with the carrier and / or with the channel. It is conceivable that the carrier and the channel are firmly connected to the separating element, wherein the possibility is included that the carrier, the channel and the separating element are integrally connected to each other and are made of the same material. The functional part can thus be produced in one process step, wherein it is designed simultaneously with the carrier, the channel and with the separating element, whereby a reduction in the component of the door handle can be achieved.

It can also be provided that the channel is movably and / or removably arranged on the separating element, in particular that the channel is hinged to the separating element. Depending on the geometry of the cavity or of the gripping part, it may be necessary for the channel to be designed to be movable on the functional part in order to guide the functional part into the corresponding position or position within the cavity in the gripping part. In one possible embodiment of the invention, a film hinge for articulated connection of the channel may be provided on the separating element.

The positioning of the first and the second, Vergussmassenfreien space can be done in different ways. This means that both rooms can be arranged in different places within the cavity. For example, the separating element may be arranged such that the separation of the cavity in the longitudinal direction or in the transverse direction of the handle part is present. For example, the first space may be located adjacent to the second space, or the first space may be positioned above, laterally offset, toward the second space. At this point, it should be noted that depending on the geometric configuration of the cavity of the handle portion of the first room and the second room may have different positions, always the partition both spaces reliably sealingly separated from each other, so that escape of potting from the first Room in the second room is avoided as possible.

Furthermore, it can be provided that a cable element is provided, which is arranged on the channel or extends within the channel, wherein the cable element is connected to the electronic component. Of course, it is conceivable that the electronic component wirelessly exchanges data, signals, etc. with electronic components arranged outside the door handle.

The door handle may include sensor elements that, for example, detect an authorized user who is in the vicinity of the door handle. The sensor element (s) may, for example, be connected to the electronic component. The sensor element may be designed, for example, as an electrode. The detection of the user can be done for example via a capacitive sensor, piezo sensor, optical sensor, etc. The sensor element may, for one, be located in the first room and, secondly, in the second room.

Advantageously, the gripping part can have at least one first opening, which is closed by a first closing element of the channel. The grip part can be designed, for example, to be open on one side, wherein the first opening can lie on the open side, through which the functional part can be introduced into the cavity. So that the cavity is reliably sealed, the first closing element closes the first opening of the handle part, so that no moisture, dirt, dust particles etc. can penetrate from the outside into the door handle. The closing element is preferably adapted to the geometry of the first opening, so that in the inserted state of the functional part, the first opening is completely filled by the first closing element.

In addition, the handle part may have a second opening which is closed by a second end element of the carrier. Thus, it is conceivable that the handle part has two openings, wherein both openings are reliably filled in each case by a matching first and second end element of the functional part, so that both the first space and the second space reliably closed from the outside world by the respective end element and are sealed.

The invention may further be formed in that the first and / or the second closing element and / or the separating element have sealing means. The sealing means may be, for example, a static seal, which is in particular a metallic seal, a soft material seal or a sealant. The sealant may, for example, by pressing the unevenness of the present sealing surfaces, which arise in particular in the cavity and on the first, second end element and on the separating element adapt. The sealing means may be formed as a rubber-elastic sealing lip.

Advantageously, the channel which runs through the Vergussmassenfreien space, rigidly executed. It is also conceivable that the channel consists of a deformable and / or elastic material, so that the channel can be adapted in its leadership of the geometry of the cavity.

It may be particularly advantageous that the channel has an inlet opening and an outlet opening, wherein in particular the outlet opening is located on the separating element. The potting compound can thus be conveyed through the inlet opening into the channel, wherein the potting compound then leaves the channel at the outlet opening and flows into the first space, at the same time the electronic component is enveloped by the potting compound, whereby the components of the electronic component protection against moisture, Dust, foreign bodies, water, etc. obtained after the potting compound is cured. In this case, the separating element can be designed with the outlet opening.

The potting compound may be formed of synthetic resin. The potting compound may be a polyester resin, polyurethane resin, epoxy resin, silicone resin or a vinyl ester resin. It is also conceivable that the potting compound is a one-component resin of a premixed resin system in which the curing reaction begins only above a starting temperature. Storage below the starting temperature may delay hardening. In addition, the potting compound can be designed as a multicomponent resin in which resin and hardener and possibly other additives such as fillers, paint, accelerator, etc. are brought together by mixing immediately before potting. Depending on the product, the resin system can then react at room temperature or only after heating. In addition, it is alternatively conceivable that the potting compound has filled resin, the mineral additives such as quartz, sand, chalk, etc., whereby advantageously the shrinkage during curing and the expansion coefficient of the finished molding material is reduced. Likewise, the resin of the potting compound can be designed such that curing takes place only after irradiation, for example with ultraviolet radiation or upon contact with a catalyst or moisture.

Expediently, the first space has a volume V1 to be filled, which amounts to at most 80% of the total volume of the cavity, in particular V1 being at most 50% of the total volume of the cavity and more preferably V1 being at most 50% of the total volume of the cavity. Depending on the position of the separating element, which has a defined distance to the first and the second closing element, determines the volume to be filled of the first space.

Advantageously, the grip part is movably mounted about a pivot axis on the motor vehicle, the first space, which is arranged on the region of the grip part facing the pivot axis, having a greater mass inertia than the inertia of the second space, which is arranged on the region of the grip part is, which is remote from the pivot axis. The displacement of a larger mass inertia in the direction of the pivot axis of the grip part in the event of a possible accident reduces the fact that the grip part is less able to move out of the door due to centrifugal forces that occur. The advantageously acting on the handle part crash lock thus requires less weight for the mass balance to reliably hold the handle immobile at the door in an accident.

The functional part may be embodied in a further embodiment of the invention such that the separating element is arranged variably displaceable on the functional part, so that depending on the application, the volume of the first space to be filled is variable.

The object is further achieved by the independent claim 17. Here, a functional part is provided for a door handle, in particular a vehicle, wherein the functional part is insertable into a cavity of the door handle and has at least one electronic component, wherein the functional part is formed such that within the cavity at least two separate spaces form, thereby a first space in which the electronic component is located, a potting compound can be introduced, and at the same time the second space is Vergussmassenfrei durable.

• a, Einführen des Funktionsteils mit der Elektronikkomponente in die Höhlung, wobei das Funktionsteil gleichzeitig die Höhlung in mindestens einen ersten und einen zweiten Raum abdichtend trennt, wobei die Elektronikkomponente sich lediglich in dem ersten Raum befindet,
• b, Befüllen des ersten Raumes mit der Vergussmasse, wobei der zweite Raum vergussmassenfrei verbleibt.

In addition, the above object is achieved by the patent claim 19. Here, a method for introducing a potting compound is proposed in a door handle, wherein the door handle has a handle to be detected by the user, which has a cavity in which an electronic component is attached to a functional part, the method comprising the steps of

• a, inserting the functional part with the electronic component into the cavity, wherein the functional part sealingly separates the cavity into at least a first and a second space, wherein the electronic component is located only in the first space,
• b, filling the first space with the potting compound, wherein the second space remains Vergussmassenfrei.

It is particularly advantageous that the functional part has a plurality of functions. On the one hand, it serves as a carrier for the electronic component. On the other hand, at least two spaces can be provided within the cavity, which are determined by the geometry and design of the functional part. In addition, the functional part ensures at the same time with its construction that the potting compound only passes into the first room without the potting compound can penetrate into the second space.

The door handle may be a stationary door handle of a motor vehicle. It is also conceivable that the door handle is a folding handle, a swivel handle, etc. The door handle may be designed to a side with a handle dome, which projects into the door and is used to operate a lock arranged on the motor vehicle. On the one hand, the grip dome can only be arranged on the grip part. It is also conceivable that the handle dome is part of the functional part, in particular arranged on an end element of the functional part, molded or fixed.

In the case of a movable door handle, it may be provided that a bearing arm extends from the grip part into the motor vehicle door. The bearing arm is correspondingly movably mounted within the door, so that the door handle can pivot out of the door, turn or move when actuated accordingly. The bearing arm may be a part of the handle part. It is also conceivable that the bearing arm on the functional part, in particular arranged on a closing element of the functional part, molded, fixed, etc. is.

The electronic component can in this case comprise various electronic components which are used, for example, in a "keyless entry" system of a motor vehicle locking system.
