Description: "Electromechanical device with computerized control and method for performing and checking automatically the opening and closing of motor car doors". The present invention is inserted into the motor car industrial branch, in particular into the one of the manufacture of accessories for motor cars. In fact, the invention concerns an accessory device which, although not indispensable for the motor car operation on which it is fitted, contributes to increase the aestetic effect, already positive by itself, of the car and furthermore qualifies its image in its whole. The technical task the invention must solve, in fact, in te one of performing tha automatical shutting and opening of a motor car doors. The invention purpose,therefore, is to propose a device for performing automatically the opening and closing of a motor car doors, so as to guarantee the continuous operation of the elements which compose it and as free of errors as possible, the whole supplying the required security for the user. This purpose is obtained * in accordance with what is claimed in the claim 1) . -The characteristics of the invention are more evident with spe¬ cial reference to the attached drawing tables, in which: Fig. 1 sc ema ca y us ra es rom a ove a par o a motor car with a fitted door; Fig. 2 and 3 illustrate the particular D of fig. 1 in enlargement respectivelty seen from above and from lateral view; fig. 4 illustrates the particular E of fig. 1 in enlargement; fig. 5 shows a simplified block scheme of the unit for electronic control. With reference to the above figures is possible to note the car 1 with its door 2 which can turn around axle R according to opposite senses respectively on opening A and closing C. The device 3 foreseen for the door opening and closing, is made evident by particular D and is seen enlarged in figures 2 and 3. The device consists of organs 63 and organs 67, described in the next pages, the operation of which, in mutual coopera- tion, is checked and controlled by a central electronic unit 60 (fig. 5). A for instance rectangular shape base 10 is supporting the components of the device and is horizon¬ tally fitted inside the car near the hinge axle of door 2. On base 10, a longitudinale guide 11 is fitted along which a sled 12 is sliding coupled to it, according to well known tecniques, with, a 1 rack 9 on its upper side. The sled 12 can slide longitudinally to the plate according to opposite advancement senses AA and back move AC (fig. 1 * and 3). At one end of the sled 12, corresponding to door 2, the end of a stem 13 is hinged, the remaining end of which is articula¬ ted on the inside part of the door 2 by means of a connecting element 4. On the side of the guide 11, on the base 10, two small vertical colomns 14a and 14b are fitted which pass into the inside of as many compasses 16a and 16b fixed on the side walls of the involucre of a speed reduction gear 15 which thus can vertically translate according to opposite senses ~rispectively of lifting S and lowering B. On the upper side of the reduction gear 15, a first motor 20 is fitted with its shaft connected to the same reduction gear. On the outlet shaft 19 of the reduction gear and by •* a gear wheel 18 is keyed, on the upper side of which an "encoder" 21 is coupled by means of a gear 22, the task of which is described here after. At one side of the reduction gear 15, a small block 17 is fitted in a internal thread. With the internal thread of block 17, a threaded bar 23 is engaged which, by means of a flexible coupling 24, is connected to a second motor 25 supported by a vertical plate 26 connected to base 10. On plate 26 two limit switches are fitted too, the one above the other, respectively the higher one 27 and the lower one 28, between the two limit switches, and appendix of block 17 is located. The particular E of fig. 1, on the contrary individuates organs 64 and organs 53 which are illustrated enlarged in fig. 4 and fitted inside door 2 near lockset 47. The organs 64 include a motor 30 which carries over a cam 32 according to a fixed sense M, through a suited speed reduction gear 3, the above cam can act on two limit switches 33 and 34 respectively, according to its position. On cam 32 the end of a line 35 is hinged to form a pisto rod-crank system, the remaining end of which is clamped to the unhooking device of lockset 47. The organs 53 task is to complete the door 2 closing up to when this last one is blocked by lockset 47. The organs 53 include a motor-coaxial reducer assembly 54, on the outlet shaft of which a flange 55 is keyed which turningly supports a roller 56 on its opposite side as to the motoreducer S . According to the flange position, the roller comes in corre¬ spondence with tally plane 57, properly positioned on part 58 defining either the beating for the door 2 or above the same plane. The control electronic unit is fitted with a microprocessor '61 connected, by means of proper electrical /electronic circuits, with a memory unit 62 of the type with onl reading (EPR0M) , in which the programme has been previously located according to which the checking unit foreseen of the reading/writing type (RAM) , which the micropro¬ cessor uses for stationing the transit and service data. The device working is as described by the modalities as follows. The programme implemented by the microprocessor 95 first of all foresees the independent check of more door opening devices (two in the present case) performed by only one central unit 60, by means of a tecnique known as "multita¬ sking" or "time-sharing", which foresees the subdivision in time terms, of the central unity activity among the different 100 devices fitted in the car. For brevity and clearness reasons, reference will now be made to only one device, with the obvious consequence that the same considerations have to be considered in force also concerning other devices if any. First of all, the microprocessor picks up the condition 105 of the car by the sounding of a movement sensor and, if the car is running, it breaks out the device working. Subse¬ quently,' the microprocessor performs a scan of two keyboards 49 and 51 fitted inside the car an on a distance control device respectively (via radio for instance) . If the keys 110 of one of the keyboards 49 and 51 are pressed in a previously fixed sequence, the microprocessor 61 causes the motor 25 start which imposes the axial rotation according to a sense fixed in advance (anticlockwise for instance) to the threaded bar 23 and causes the block 17 movement and, therefore, 115 the one of the reducer 15 according to the lowering B sense. When the block 17 acts with the appendix on the lower limit switch 28 causing the motor 25 stop, the gear wheel 18 is engaged with the rack 9 of sled 12. Furthermore the micropro¬ cessor 61 avails itself of a time counter 6 properly sected, 120 in accordance 'with the programme instructions, for each mechanical movement controlled by the central unit 60. By means of a periodical checking of the time counter 6, the microprocessor anyhow cuts out the motor 25 feeding after ; a time fixed in advance (2 seconds for istance). In the 125 case of an uncorrect working of the lower limit switch 28, the stop of the operation is anyhow assured after a reasonable time. At this point, the microprocessor 61 checks the non-in¬ terference of roller 56 with plane 57; in case of the roller interferences with the checking plane, motor* 54 is started 130 until the flange is brought in a position so that the roller is above the same plane. Said position is individuated by a limit switch 48 on which can act the flange. Subsequently according to the programme instructions, the microprocessor activates the third motor inside door 2 of the car. Therefore, 135 the cam 32 turns according the sense M as long as it reaches the limit switch 34 which stops the motor 30 and, therefore, cam 32. The line 36 acting on the unhooking device of the lockset, disengages the door 2. If the microprocessor get no consentment from the limit switch 34 within a time fixed 140 in advance (1 second for istance), the operation is interrupted and the faulty operation is warned. In this case, the time inspection does not carry out an accessory check but an operational one. As soon as the microprocessor has received the limit switch 34 consentment, it lets the motor 20 start 145 which, through the reducer 15 and the gear wheel 18, causes the transfer of sled 12 according to the advancement sense AA. For a short interval of time (0,3 second for instance), the highest tension is given to the motor in order to obtain such a deflecting torque on the motor shaft 20 to shift 150 readily and quickly the inertial mass of the door, which in a rest state, and to overcome the door frictions against the walls of the respective seat in the car side. When the motor 20 feeding tension has been restored up to the working value, corresponding to a proper opening speed of the door, 155 the microprocessor carries out an iterative sequence . of checkings by means of photcells 8a and 8b, fitted in correspon¬ ding seats properly carried out and located on the outer surface of the door 2, as well as of the encoder 21, to detect possible obstacles to the door opening, and contempora- 160 rily it carries out a scan of the keyboards 49 and 51 -fitted inside the car and the radio control respectively- testing, at the same time, the opening limit switch 41, the car motion sensor 46 an the time counter 6. If a positive checking is obtained from one of the photocells 8a or 8b, or from 165 the e coder 21, the microprocessor controls the inversion of the motor 20 for a period of time fixed in advance (0.7 second for instance), by shutting the door for a short time, and stops the door opening. In instead the microprocessor has a positive checking from the car movement sensor 46, 170 n this cas too the door opening operation is interrupted, but the door is completely closed again. The opening operation of the door is interrupted in the same way if the key of the keyboards 49 and 51 are pressed in a second sequence fixed in advance, according to the user's intention to stop 175 opening, or by opening limit switch 41 • (intercepted by a first checking 39) after the door has reached its maximum opening, with the operation completion. The pressure of the same keys in a third sequence fixed in advance or the car start let the device pass directly to the closing phase 180 of the door. If, on the contrary, the time counter 6 "informs" the microprocessor 61 that a time fixed in advance, certainly longer than the one required to perform the opening operation (6 seconds for instance) has elapsed from the beginning of the motor 20 start, a defective operation is warned and 185 the feeding to motor 20 is interrupted. Also in this case, the time checking becomes an operational purpose. The micropro¬ cessor 61 subsequently carries out a new iterative scan of the keyboards 49 and 51 pushbuttons, both of the car inside and of the one fitted on the radio control, of the 90 car movement sensor 46, of a weight sensor 45 fitted under the seat concerning the door 2, and of the time counter 6. If the microprocessor 61 has a positive checking from an opening pushbuttom, it arranges the operation completion of door opening, also if interrupted before the end of the 195 previous phase, or it ignores the received control and resumes the scan if' the door is already completely opened. If the keys of the keyboards 49 and 51 are pressed in.a third sequence fixed in advance, or if the microprocessor has a positive checking from the movement sensor 46 of the car, the device 200 passes directly to the door closing phase. If, on the contrary the microprocessor has a negative checking from the weight sensor 45 (the person has got up from the seat), it continues the scan for an additional time fixed in advance (2 seconds for instance) and if no changes intervene on the tested 205 components, it arranges itself in advance in a waiting phase and continues scan. If the pushbuttons of the keyboards 49 and 51 are pressed in either first or third sequence, the microprocessor passes directly to the relevant phases, respectively according to what described as follows. If, 210 on the contrary, a person seats down on the seat, the weight sensor 45 "informs" the microprocessor which, after a waiting time fixed in advance (2 seconds for instance) to allows to this person to adjust himself, passes to the door closing phase. The microprocessor 61 arranges the immediate shutting 215 of the door if it feels the car movement. The shutting opera¬ tions begins by the organs 64 checking. If the cam 32 acts on the limit switch 34, the microprocessor intervenes to activate the driving motor 30 which lets the cam 32 rotate as long as this one interests again the limit switch 33. 220 Normally, however, this last operation is carried out immedia¬ tely after the door 2 disengagement during its opening phase. The lockset can thus in any case block again the door 2. In want of a positive checking of the initial switch_ 33, after a time fixed in advance (for instance 1 second), the 225 defective operation is warned and the programme is resumed from the beginning. Is the signal from the limit switch 34 received, the microprocessor 61 checks again the non¬ interference of roller 56 with plane 57; in the case of interference of the roller with the checking plane, the motor 54 is activated so as to bring the fiance in such a position that the roller is ' fitted above the same plane. At this stage, the microprocessor activates the motor 20 with a rotation sense contrary to the one foreseen for opening, thus causing the transfer of .the sled 12 according to the set-back towards. The motor 20 is activated, in accordance with the program instructions, according to phases in succession. At first, for a length of time fixed in advance, the motor 20 is fed with the highest tension to shift the door inertiual mass. Subsequently, the door continues with standard speed as long as a second checking 40 intercepts a closing limit switch 42. During this phase, an iterative scan of the keyboards 49 and 51 as well as of the encoder 21 is carried out, so that the closing phase of the door is affected like what...happens during the opening phase in consequence of an event (for instance pressure on the keys). Even in this case, the parallel checking of the time for carrying out the door movement enables to point out a defective operation, if any. In particular, if during the scan in the second phase, the microprocessor has a positive checking from the encoder 21, the motor 20 is immediately stopped and the door is re-opened, retaking the program execution from the point already mentioned above, which corresponds to the blocking of the opening operations (in consequence of an interruption or of the operation completion) . The closing of the limit switch 42 causes the encoder 21 disability by the microprocessor 61 and imposes again the maximum feeding tension of the motor 20 with a view to increasing the shutting speed according to C in the last part. However, the accelera¬ tion of the closing movement of the door is not indispensable 260 and, consequently, it can be excluded from • the program. As soon as the door has reached the nearly closed position, i.e. when the microprocessor has received the confirmation that the door has approached the car side, by means of the limit switch 42 on which the second checking 40 is acting, 265 the microprocessor ativates the moto reducer 54 up to let the flange rotate by 360°. By performing a circumference, roller 56 running on an arch of this one fixed in advance, presses on the checking plane 57. Therefore, on the door a direct traction is made towards the car inside, which 270 traction causes the final blocking of • .the door by means of lockset 47. Whena proximity sensorium 43 has confirmed to the microprocessor 61 that the door closing has been completed, this sensorium controls the motor 25 starting with an anticlockwise rotation, thus lifting according to 275 S of the motoreducer until the block 17 goes to affect the upper limit switch 27. In a parallel way, a check on the time is effected and, if after a time fixed in advance (2,5 seconds for istance) the microprocessor receives no positive checking from the upper limit switch 27, the defective operatio 280 tion is signaled and the execution is resumed from the beginn¬ ing of the program. When the lifting of the motoreducer 15 has been completed, with consequent disengagement of the gear wheel 18 from the rack 9 of the sled 12, the program execution is resumed from the beginning. By-procedures may 285 obviously be foreseen, properly inserted in the program. If for istance, the device is mounted on collapsible hood cars, before the opening and closing of a door, the micropro¬ cessor must control the lowering of the relevant glass for a length fixed in advance, and to then foresee its lifting 290 after the operation has been completed. This in order to disengage the glss from the relevant seals which, otherwise, would hinder opening and closing on account of the high frictions with the door windows. The central unit 60, futhermo- , of the car motor by properly modifyingthe program which is fitted into the EPROM memory unit and by arranging in advance the proper interconnection devices, in well known types, between the central unit and motor starting device, through proper interfacing units. From what precedes, it is evident that the device meets the requirements of the premise, by offering a safe and trustworthy operation. Furthermore, the sizes of the device enable its fitting without affecting the spaciousness. This is possible through the central unit and the program implementation just foreseen for the micropro- cessor. By means of proper mechanic and/or electronic regula¬ tions of the device components (which have bot been described because obvious for a techician of this sector) , it is possible to change the speed and width of the door opening, as well as the performance times of the different operation phases. The high versatility of the device thus enables to fit it on different car models, even very different the one from the other. Furthermore, it is to point out that the organs 53, which complete the: door shutting, as per description, do not interfere with the normal operation of the lock fitted on the door by the car manufacturer. They do = not require either modifications of the original opening and closing systems of the doors. At last, by pressing the keys of the boards 49 and 51 according to any different sequence whatever than the ones mentioned above, all open or in opening doors are immediately closed, as well as the positioning of flange 55 by activating the motoreducer 54 in a position so that the roller interferes with the checking plane 57. This position is located by means of a limit switch 50 on which the flange can act. Therefore, all doors are blocked and cannot be opened in any way but by introducing a code fixed in advance through the keyboards 49 and 51. Not even by means of the mechanical orignal lock of the car the doors can be open ed since they are blocked by a mechanism quite independent 330 is thus performed, system which obviously can be further improved, as for instance the parallel disactivation of the motor starting system, all well known to the branch technicians. What precedes obviously has been described as an example and not a limitng one consequently any modifica- 335 tion are understood to be within the invention protection as described before and according to the following claims.
