Definitions

  • the invention relates to a locking system of the type mentioned in the preamble of claim 1.
  • This system comprises an access authorization device which consists of a stationary part arranged in the vehicle and a handset in the possession of the authorized person. If a successful data exchange between the handset and the stationary part is started and is successful, then a certain function is triggered on the lock or in the vehicle.
  • the invention has for its object to develop a reliable locking system of the type mentioned in the preamble of claim 1, which is designed to save space and can be manufactured conveniently and inexpensively. This is achieved according to the invention by the measures set out in claim 1, which have the following special significance.
  • the individual parts of the board can be easily manufactured because they are in a flat, unfolded position. Then the plate parts take up a large area, whereby the manufacture of the two electrodes and the shielding can be carried out without interfering with one another. This enables inexpensive, convenient manufacture.
  • the plate parts are folded against each other and thus brought into a compact folded position. The result is a three-layer folded product with a small footprint. You get a space-saving, compact folding product that can be easily integrated into the tight space inside the handle. This enables convenient, quick installation.
  • this folded product by integrally forming the circuit board parts in the form of three adjacent sections in an overall circuit board. These three sections are separated from one another by film hinges. Then at least one conductor track, as recommended in claim 5, can also cross the area of the film hinges and thereby electrically connect two or three adjacent sections of the folded product to one another.
  • FIG. 1 is a schematic plan view of a vehicle with an integrated locking system according to the invention
  • Fig. 4 the assembly located outside of the handle in Fig. 2 in a previous manufacturing stage, namely the top view of a preliminary product, where three hinge-like with each other connected parts of the board are in their unfolded position in a smooth, flat state,
  • FIG. 8 shows a longitudinal section through the intermediate product of FIG. 7 along the section line VIII - VIII and
  • Fig. 9 also enlarged, a partial cross section through the finished assembly of Fig. 5, along the section line IX - IX.
  • the locking system according to the invention is not only particularly space-saving, but also enables the authorized person to obtain access to the vehicle 10 particularly conveniently and quickly, but reliably prevents unauthorized third parties from doing so.
  • access to the vehicle is possible via two doors 11, 12, a tailgate 13 and a bonnet 14. All of these movable parts 11 to 14 are held in their closed position by the same or different locks 15 on the body.
  • the locks can be transferred together between their locking and unlocking positions by means of a known central control. It is sufficient to explain this in more detail using a handle 20 belonging to the door 11.
  • the handle can be formed in two parts and consist, for example, of a base shell 21 and a cover shell 22, between which there is a space 23 to accommodate a special electrical assembly 30.
  • the handle 20 is designed as a so-called pull handle, which has a pivot bearing 25 at one end and has a shaft 26 at its other end, which acts on the associated lock 15 in the door 11 via intermediate members.
  • the handle 20 is expediently arranged in the region of a recessed grip 16 of the outer paneling of the door 11, so that there is a space 17 between the handle 20 and the outer door paneling of the vehicle 10.
  • FIG. 4 shows, in a prefabrication stage 30 ', the flat initial state of the later finished assembly 30, which can be seen in FIG. 5.
  • This functioning as an overall board, includes a bendable sheet 35 on its one surface side 36, which can be seen in FIGS three conductor surfaces 41, 42 and 43 and conductor tracks 44, 45, 46 are located.
  • the sheet 35 is penetrated by two linear, mutually parallel film hinges 37, 38, which divide the entire circuit board into three strip-shaped sections 31, 32, 33. These hinges 37, 38 allow the individual sections 31, 32, 33 to be folded over 19, 29 twice to form a three-layer folded product 40 which can be seen in FIG. 6.
  • the finished folded product 40 can be held together by snap fasteners 27, 28, the two halves of which in the present case consist of a flexible hook 27 integral with the entire circuit board and a hole 28 in the sheet 35. After the folding 19, 29, the hook 27 moves through the hole 28 and automatically engages behind the outer edge region of the hole 28.
  • snap fasteners 27, 28 are arranged distributed over the longitudinal edges of the sections 32, 33.
  • fourth section 34 which, however, is formed here as an extension of the third section 33 and is therefore located outside the actual folding zone identified by 39.
  • This fourth section 34 is also formed from the sheet material 35 and likewise has conductor tracks 47.
  • various electrical components 48 are connected to the conductor tracks 47, which are part of a complex control of the locking system according to the invention. Therefore, the aforementioned conductor tracks 44, 45 and 46, which lead to the various conductor surfaces 41, 42, 43 lead from the electrical components 48 of the extended section 34.
  • the conductor tracks 44, 45 leading to the neighboring sections 31, 32 are continued without interruption over the area of the film hinges 37, 38 and therefore for contacting the conductor surfaces 42, 41 there with the corresponding components 48 of the section extension 34 worries.
  • the three conductor surfaces 41, 42, 43 each result from mutually crossing conductor tracks, which each produce a grid 49 on each of the sections 31, 32, 33.
  • the conductor tracks can be formed over the entire surface and can have any geometry.
  • the conductor surfaces 41 to 43 have different functions to perform from one another. As will be explained in more detail with reference to FIGS. 3 and 6, they each form the one electrode 51 or 52 of two different capacitive sensors 61, 62 when the finished assembly 30 is installed in the handle 20 and attached to the required components in the vehicle 10 is connected. For this purpose, electrical cables 58 and contact parts 59 protrude from the assembly 30 according to FIGS. 2 and 5.
  • the one electrode 51 generates a first electric field 50 according to FIG. 3 with respect to the body of the vehicle 10, which in the space 17 already mentioned between the Handle 20 and the recessed grip 16 arises. This field 50 should, as already mentioned, briefly “inner field” and this electrode
  • This inner electrode 51 are referred to as “inner electrode”. This inner electrode 51 is shielded from the other electrode 52 by a third conductor surface 43, which is located between them in the folded state 40 of FIG. 6 and is grounded. Its function is therefore that of a shield 53.
  • the other electrode 52 When voltage is applied, the other electrode 52 creates a second electrical field 60, as shown in FIG. 3, in relation to the surroundings of the vehicle , are referred to as “outer field”, which is independent of the inner field 50.
  • the sequence of action of the inner and outer fields 50, 60 can best be explained in more detail on the basis of the schematic structure indicated in FIG. 1.
  • the control unit 55 is connected via control lines 56 and supply lines 57 to the above-mentioned electrical cable 58 of the unit 30.
  • the locking system according to the invention also includes an electronic access authorization, which belongs to a stationary part installed in the vehicle, which is partially integrated in the control unit 55 and has one or more transmitting and receiving units 63 at suitable points on the vehicle.
  • the authorized person is in possession of a mobile part 64, schematically indicated in FIG. 1, in the form of a “check card” in which, in a manner known per se, transmitting and receiving units, data storage, power sources and control parts, also not shown, are integrated
  • the stationary part 55 can effect a mono or multidirectional data exchange 65 with the mobile part 64 of the access authorization device 65.
  • the inner field 50 and the outer field 60 then build up at the latest Handle 20. If the authorized person then reaches behind the handle 20 of Fig. 3 with his hand, he changes the electrical inner field 50 located there.
  • this first unlocking sensor 61 is to be referred to as an “opening sensor”.
  • the authorized person When the vehicle 10 is finally left, the authorized person, if he is in possession of the handset 64, can trigger an automatic locking of the locks 15. In order to close the opened door, the hand is guided against the handle 20 from the outside and therefore reaches the area of the outer field 60. Now there is a change in the penetrating hand Capacitance, which is sensed by the second capacitive sensor 62. In this case, the lock 15 or the locks are transferred into their locking position via the control. If the authorized person with the handset 64 is outside the vehicle 10, the slammed doors 11, 12 are locked and cannot be opened by unauthorized persons.
  • the second sensor 62 which is effective in this case, can therefore be referred to in an analogous manner as a “closing sensor”.
  • the control would also be possible through the control to generate the inner field 50 on the one hand and the outer field 60 on the other hand only alternately. If, for example, the lock 15 is in the locked position, the outer field 60 need not be present. Rather, it is sufficient to only build up the inner field 50 and thereby activate the opening sensor 61. If, on the other hand, the lock 15 is already in its unlocked position, the inner field 50 is superfluous. It is then sufficient to generate the outer field 60 and thus to set the closing sensor 62 effectively.
  • the shield 53 in between is also unnecessary. In this case, it would then suffice to form the folded product 30 in two layers, i.e. omit the third section 33.
  • the described section extension 34 would then be positioned on one of the two remaining sections 31, 32.
  • the inner field 50 can then easily extend over areas of the outer field 60, and vice versa.
  • the assembly 30 can be inserted as an insert into the empty injection mold and then overmolded there by the masses on all sides become. Then only electrical cables 58 and contact parts 59 protrude. Finally, it would also be possible to also integrate the transmitting and receiving units 63 belonging to the stationary part of the access authorization device. You can then also be part of the described assembly 30.
  • the bendable sheet 35 for building the described folding product 40 and the assembly 30 naturally also makes the finished assembly 30 flexible. If the handle 20 in the receiving area 23 has, for example, the curvature 66 indicated by dash-dotted lines in FIG. 2, the structural unit 30 can be bent accordingly in the sense of the arrows 67 in FIG. 2 without impairing its function. Because the folded assembly 30 is very thin and made of elastic plastic, it allows a comfortable bend 67. Due to this flexibility, the assembly 30 can be adapted to each grip profile 66 and extend over a large length of the handle 20. This promotes the good construction of the inner and outer fields 50, 60 and optimal use of space on the handle 20.

Abstract

L'invention concerne un système de fermeture comprenant des poignées (20), lesquelles sont destinées à l'actionnement des serrures qui sont désactivées en présence d'une position de verrouillage, et permettent l'ouverture de la serrure seulement si la serrure est en position de déverrouillage. Un détecteur capacitif qui coopère avec un équipement d'autorisation d'accès, détecte préalablement l'approche d'une main sur la poignée (20) et permet ainsi une commutation précoce de la serrure dans la position souhaitée. A cet effet, La poignée (20) renferme deux électrodes (51, 52) séparées par un blindage (53). Une électrode (51) produit un champ interne (50) entre la poignée (20) et le véhicule (10) et fonctionne avec la carrosserie du véhicule comme capteur interne capacitif. Quant à l'autre électrode (52), elle créée un champ externe (60) vis-à-vis de l'environnement du véhicule. Lors d'une utilisation adéquate de la poignée (20), si on glisse la main dans la zone du champ interne (50), un premier fonctionnement est alors exécuté dans la serrure ou le véhicule. Par contre, si on glisse la main de l'extérieur vers la poignée (20), les propriétés diélectriques du champ externe (60) sont modifiées, ce qui entraîne un deuxième fonctionnement de la serrure ou du véhicule.
