Abstract

A radiator shutter 1 for a motor vehicle for controlled ventilation of the prime mover. The radiator shutter 1 has a frame 2 on which at least two slats 8-11 are rotatably mounted so that they can pivot from a fully closed position (approximately 0°) to an open position (approximately 90°). The slats 8-11 are mounted on bearings on two opposite sides of the frame. A motor 12 for driving a single slat 9 is provided on the motor side 6 of the frame within or on the frame. A linkage member 7 is located on the same motor side 6 of the frame, which transmits the rotation of the driven slat 9 to the other slats 8, 10, 11 in synchronization. The radiator shutter 1 is characterized in that, on the mounting side 5 of the frame 2 that does not face the motor side 6 of the frame, locking discs 18-21 are provided for each slat in the region of the mounting parts of the slats 8-11 provided there, and the locking discs 18-21 have a shape that blocks the rotational movement of the locking discs in a force-fit and form-fit manner if at least one of the locking discs does not rotate synchronously with all the other locking discs 18-21.

Description

Technical Field

[0001] The present invention relates to a radiator shutter for a motor vehicle, made of a thermoplastic material. Further, the present invention relates to a method for manufacturing such a radiator shutter and to the use of such a structure.

Background Art

[0002] A radiator shutter for a motor vehicle is a device that guides outside air flowing into the vehicle through the front part while controlling it towards the prime mover. This reliable control of the air flow is important for the reliable management of the combustion process, i.e., for the efficiency of the prime mover and the emission of pollutants.

[0003] A radiator shutter generally consists of a group of slats arranged horizontally or vertically in parallel. The slats are rotatably or pivotably attached to a frame and can rotate from an open position (where the plane of the leaf part of the horizontal slats facing transversely to the axis of the vehicle is arranged in a substantially horizontal plane) to a closed position at an angle slightly less than 90°. Also, in the closed position, the planes of the slats extend approximately vertically and the slats overlap each other in the edge region.

[0004] The slats attached to such a frame structure are currently controlled by a small electric motor via a controller to a corresponding desired angular position predefined such that there is an optimal air supply for each operating condition.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The problem of the present invention is, in particular, to provide a radiator shutter, in particular, which can operate reliably, can be easily manufactured, in particular, is robust against malfunctions or prevents malfunctions, and / or reports malfunctions to the controller as quickly as possible for a motor vehicle.

Means for Solving the Problem

[0006] Accordingly, the present invention relates to a radiator shutter for controlled ventilation of a prime mover, particularly for a motor vehicle, the radiator shutter having a frame to which at least two slats are rotatably mounted in such a manner.

[0007] These slats are arranged such that the leaf portions of the slats are substantially parallel to the plane of the frame, and in adjacent regions to each other, they partially overlap or are in close contact with each other, and from the fully closed position (about 0°) where the frame opening is substantially closed against the air flow, the leaf portions of the slats are arranged substantially perpendicular to the plane of the frame, and can pivot to the open position (about 90°, usually about 85° in practice) where the frame opening is substantially maximally open to the air flow.

[0008] These slats are attached to bearing points on two opposite side portions of the frame. In addition, a motor for driving a single slat is provided on the motor side portion of the frame, preferably integrated in a suitable frame region within or on the frame. In addition, a connecting member for synchronously transmitting the rotation of the driven slat to other slats is provided on the same motor side portion of the frame.

[0009] The proposed design provides a locking member for each slat in the region of the attachment portion of the slat provided there, on the attachment side portion of the frame facing away from the motor side portion of the frame. This locking member preferably realizes the function that when a single slat stops rotating out of synchronization with other slats (including the driven slat), the rotational movement is automatically locked by these locking members at this attachment side portion facing away from the motor. This is recognized by the motor because an increased torque necessarily occurs suddenly as a result of an abnormal stop not expected in the normal operating state.

[0010] Thus, in the mounting side portion of the frame facing the side opposite to the motor side portion of the frame, in the region of the mounting portion of the slats provided therein, locking members are provided for each slat, and the locking members are directly or indirectly connected such that when at least one of the locking members does not rotate synchronously with all the other locking members, the rotational movement of the locking members is blocked in at least one direction, preferably in a manner of force fit and / or form fit.

[0011] The locking members can be formed as separate members from the actual slats, so that when the slats are damaged, the locking members still remain within the frame and the locking function can be ensured, for example, by means of locking rods or by interaction with adjacent locking members. Alternatively, the slats can be designed to be connected to the actual slats or even formed as an integral part with the actual slats. Thereby, it is preferable that the locking members are surely retained within the frame even if the slats are damaged. For this purpose, for example, the connection portion (e.g., in the form of a connection pin) between the locking members and the slats can be formed as a removable plug connection or as an intended breaking point, whereby in any case the locking members remain within the frame even if the slats are damaged. To assist this, the locking members can be held at least partially within the frame or within an additional cover of the frame (e.g., by corresponding contours in the cover) such that the locking members cannot be completely removed from the frame or this cover in case of damage to the slats.

[0012] A locking disk is provided, and the locking disk preferably has a shape that blocks the rotational movement of the locking disk, particularly in a manner of force fit and / or form fit, when at least one of the locking disks does not rotate synchronously with all the other locking disks.

[0013] According to the first preferred embodiment, this design is characterized in that at least three, preferably at least four, particularly preferably exactly four slats are attached in parallel in the frame.

[0014] A further preferred embodiment is characterized in that each locking disk is connected to the associated slat in both rotational directions, and the locking disk preferably has at least one locking plate disposed substantially perpendicular to the respective slat axis.

[0015] A further preferred embodiment is characterized in that at least the first locking plate has a radius that is larger in the first circumferential region, preferably than in the second circumferential region substantially opposite thereto.

[0016] A further preferred embodiment is characterized in that there are preferably two adjacent locking plates offset with respect to the shaft of the locking disk, and in particular, the second locking plate preferably has a lateral protrusion on the side.

[0017] A further preferred embodiment is characterized in that at least one locking disk, preferably all locking disks, are designed to be mirror-symmetrical with respect to a mirror plane including the shaft.

[0018] A further preferred embodiment is characterized in that in the non-locking operating state, the minimum distance between the locking disks is always maintained, and this minimum distance is preferably in the range of 0.1 mm to 5 mm or 0.1 mm to 4 mm, preferably in the range of 0.1 mm to 1 mm, particularly in the range of 0.25 mm to 0.75 mm.

[0019] A further preferred embodiment is that the locking member has at least one engagement pin offset radially with respect to the rotation axis of the slat, the at least one engagement pin extends parallel to the rotation axis of the slat, and during rotation of the slat, it moves in an arc synchronously with the slat, and the engagement pins of all the locking members are connected via a common locking rod extending perpendicular to the axis of the slat.

[0020] Preferably, the engagement pin extends into a locking recess in the locking rod, and the locking recess is preferably configured as a slot or an elongated recess whose longer axis extends perpendicular to the main extension direction of the locking rod. The slot or the elongated recess can be configured as a through-opening or a groove, particularly in the form of a slot-shaped guide. The slot or the elongated recess is not closed on at least one side for easy attachment to the locking rod, and this open side can also be closed later by additional parts for operation. Particularly with regard to this open design, it is advantageous when the slot or the elongated recess is designed in the form of a groove rather than a through-opening. The locking rod can be further preferably attached such that it can be displaced only substantially along the main extension direction and cannot be displaced in a direction perpendicular to the main extension direction. For this purpose, corresponding guide grooves arranged along the main extension direction of the locking rod, or corresponding through-openings with which stationary guide pins engage, can be provided.

[0021] Preferably, in the fully closed position or the fully open position, the engagement pin is deflected substantially maximally in the main extension direction of the locking rod with respect to the rotation axis of the respective slat, and during rotation to the fully open position or the fully closed position, it rotates to a position located in the main extension direction of the locking rod substantially at the height of the rotation axis of the respective slat. In the fully open position or the fully closed position, the engagement pin preferably comes to be located in the end region of the slot or the elongated recess respectively.

[0022] The slot or elongated recess preferably has a retaining depression and / or a lateral offset portion in the maximum deflection direction of the engagement pin, preferably in the middle of the slot or elongated recess, respectively.

[0023] The locking rod can be displaced in the locking guide only in a single direction perpendicular to the rotation axis of the slat and cannot be displaced in a direction perpendicular to the plane covered by the rotation axis of the slat, and can be guided accordingly.

[0024] A further preferred embodiment is characterized in that the locking disk is formed as a separate part from the slat, and the bearing pin of the slat is preferably inserted into the locking disk so as to be fixed exclusively against rotation.

[0025] A further preferred embodiment is that the locking disk is arranged within the enclosed area of the frame, separated from the through-opening of the frame by a partition wall, and preferably, the bearing pin of the slat engages through the through-opening in the partition wall. The mounting projections of the locking disk can further engage with the through-openings in the partition wall, and these mounting projections can be configured to have blind holes or through-openings, and the corresponding bearing pins of the respective slats are adapted to engage with these holes. It is preferred that there is a corresponding structuring of the interior of this opening and the outer contour of the mounting pins of the respective slats, whereby the slats are inserted so as to be fixed against rotation. In addition, axially extending sliding webs can be provided outside such mounting projections, and these sliding webs slide only in the corresponding receiving openings in the frame or in the area of the corresponding partition wall, so that they are less affected by contamination.

[0026] A further preferred embodiment is characterized in that the slats have a length in the range of at least 10 cm or at least 20 cm or at least 50 cm, preferably more than 60 cm or more than 1 m, particularly preferably in the range of 10 cm to 150 cm or 20 cm to 120 cm, or else in the range of 1.2 m to 2 m, and in particular, a vertical intermediate web that supports the intermediate mounting region of the slats is preferably provided on the frame.

[0027] This structure can also be a radiator shutter having two or more slat regions, for example, two slat regions on both sides. The slat regions can be individually driven by motors respectively, or preferably, both can also be driven by the same motor. In the latter situation, this motor is preferably arranged in the middle between the two slat regions, and the locking mechanism is individually arranged outside each slat package in any case. In this situation, when a central motor is used, it is possible to select a connecting rod that moves both slat packages as an integral part or at least in a firmly joined state.

[0028] In particular, when the individual slats have a torsional stability unsuitable for feedback to the motor, in order to ensure sufficient feedback to the motor in case of blockage or failure of the slats, one of the slats in the slat package can be selectively formed to have a higher torsional stability than the other slats, or an appropriate separate transmission member having torsional stability can be provided instead of or in addition to the slats (for example, arranged above or below the slat package in the frame).

[0029] A further preferred embodiment is characterized in that the slats have cavities related to manufacturing extending along the axis of each slat inside.

[0030] A further preferred embodiment is that the connecting member is formed as a connecting rod, and the motor preferably drives the driven slat directly through its axis, and preferably the connecting rod arranged parallel to the plane of the frame and perpendicular to the axis of the slat moves through a connecting lever, and the other slats move synchronously through the corresponding connecting levers connected to the connecting rod.

[0031] In addition, the present invention relates to a method of operating or controlling the above radiator shutter, characterized in that the motor controller is designed such that when the motor moves to a locked stop position not corresponding to the closed end position or the open end position of the slat due to the locking of the locking disk, an error message is output, and reaching such a locked stop position is detected by an increase in the torque generated by the motor.

[0032] Furthermore, the present invention relates to a method of manufacturing the above radiator shutter, characterized in that the frame, the slat, and the locking disk are individually manufactured in an injection molding process from a thermoplastic material, preferably a glass fiber reinforced thermoplastic material, particularly preferably a glass fiber reinforced thermoplastic polyamide, and then assembled to form the radiator shutter.

[0033] Finally and importantly, the present invention relates to the use of the above radiator shutter as an air inlet control member for performing a specific air supply to a prime mover (internal combustion engine, electric motor), prime mover parts, an energy storage unit (e.g., a battery of an electric vehicle), or another heat generating component in a motor vehicle or generally in a means of transportation, particularly in a motor vehicle.

[0034] Further embodiments of the present invention are described in the dependent claims.

Embodiments for Carrying Out the Invention

[0037] Figure 1 shows a radiator shutter 1 having a frame 2. The frame has two horizontally opposed long sides and two vertically opposed frame sections. The vertical frame section shown on the right side of Figure 1 has a side fastening region 4, and an attachment region 5 for horizontally extending slats is provided in this frame section shown on the right side. In Figure 1, such a radiator shutter attached to a motor vehicle is shown from the prime mover side. Before attaching to the vehicle, an inner cover is additionally attached, but in Figure 1 and subsequent drawings, the inner cover is not reproduced in order to show the internal functions of the frame.

[0038] The slats 8 - 11 extend horizontally over a length longer than 1 m. The slats 8 - 11 are attached to and driven at the vertical frame side part shown on the left side of Figure 1, i.e., the motor area. The slats 8 - 11 are further attached to the other side part, i.e., the attachment region 5 of the frame. Due to the long length of the slats 8 - 11, there is a vertical intermediate web 3 in the frame, and further slats are also attached to the vertical intermediate web 3. For this purpose, as can be seen from the exploded view shown in Figure 2, the slats each have intermediate attachment parts 8'' - 11''. Here, the slats are each formed in a cylindrical shape and do not have actual slat leaf parts 17 extending on both sides of the central axis of the slat. At the motor side part 6, the frame has appropriate recesses, and the motor 12 can first be inserted into a motor holder 15 which is an injection - molded part so that it can be inserted into the recesses. Since the motor shaft is directly or indirectly connected to the bearing head 9''', the motor directly drives the second - from - the - top slat having the reference numeral 9. The slats are attached at the motor side via such bearing heads 8''' - 11''', and at the opposite side via bearing pins 8' - 11'.

[0039] For installation, first insert the slat together with the bearing pins 8’ to 11’ into the corresponding mounting recesses in the mounting area 5 and then into the corresponding bearing points in the motor holder 15. For this purpose, it is preferable to pre-insert the motor 12 into the holder 15 and then insert it into the frame together with the slat package until the intermediate support parts 8’’ to 11’’ engage with the corresponding recesses 17 in the vertical intermediate web 3. Subsequently, the intermediate mounting part can be closed from the front side by the cover 16.

[0040] As already described above, the motor 12 is connected to the bearing head 9’’ of the driven slat 9. The motor moves the slat between a fully closed position (0°) where the lateral ends of the slats just slightly overlap each other and a fully open position (about 90°) where the plane of the slat is substantially perpendicular to the plane of the frame and the air passage is maximally open. The closed position is shown in Figure 1.

[0041] To make the movement of the other slats 8, 10, 11 interlock with the movement of the driven slat 9, a connecting rod 7 is provided. The connecting rod is driven via an eccentric on the driving slat 9 and synchronously moves the other slats 8, 10, 11 which also have similar eccentrics.

[0042] A radiator shutter with a locking member is shown in Figure 3. The corresponding exploded view is reproduced in Figure 4. Similar or identical elements already described with respect to Figures 1 and 2 will not be described again below.

[0043] In the attachment region 5, here, the OBD disks 18-21 (OBD represents On-Board Diagnosis, an in-vehicle fault diagnosis device) are fitted to the ends of the slats here. The functions of these disks will be described in more detail below. Therefore, the ends of the slats facing away from the motor, shown on the right side, are no longer directly attached to the frame but are attached to these OBD disks 18-21. The OBD disks 18-21 are used as the locking members mentioned at the beginning. Preferably, all of these disks 18-21 have the same dimensions and are manufactured from a thermoplastic material, preferably polyamide 6 with a glass fiber content of about 50%, in an injection molding process, just like the frame and the slats.

[0044] When a defect occurs on the side facing away from the motor, a reinforcing member 39 is provided in the region of the slat facing the motor here so that it is possible to absorb the increased torque caused by being locked. Here, the reinforcing member is formed as a separate part to be screwed, but preferably, it may be manufactured as an integral part simultaneously with the slat in an injection molding process. On the other hand, the locking members, i.e., the disks 18-21, are formed as separate members from the slats 8-11. This is important because if the entire slat is damaged, the related OBD disk may also be damaged, and the locking function cannot be detected in the event of a defect. Here, also in the event of a defect, due to the larger torque that may exist due to locking, the connecting rod is also formed more strongly than in the example shown in FIG. 1.

[0045] Somewhat different further designs of such radiator shutters having locking members are shown in FIG. 5. The corresponding exploded view is reproduced in FIG. 7. In this exemplary embodiment, as can be particularly seen with reference to FIGS. 6 a) and b), there is no reinforcing member 39 in the form of a separate part screwed to the motor side. Here, each eccentric wheel is more firmly designed in the form of a connecting lever 25 of each slat. The connecting lever 25 each has a connecting pin 26 facing the connecting rod 7. These connecting pins 26 each engage in a corresponding connecting groove of the connecting rod 7. Again, the motor 12 directly drives the corresponding bearing head 9''' of the driven slat 9. Correspondingly, the interlocking with the other slats is effected via the connecting lever 25 of the slat 9 with respect to the connecting rod 7 and then from the connecting rod 7 via the corresponding connecting lever 25 of the other slats with respect to the other slats.

[0046] FIG. 6 b) shows the locking members 18 - 21 arranged in an enclosed space 22 for protection against dust etc. Thus, it becomes impossible for water, dust etc. to act on these locking members which are important for the diagnosis. The enclosed area 22 is closed on the front side and, similarly, on the back side, which is further closed when finally assembling the frame cover not shown here. Thus, the enclosed area 22 of the locking members is substantially completely separated from the frame opening 37 where air and further dust and water etc. could flow in by the partition wall 23.

[0047] The functions and shapes of the locking members 18 to 21 can be best explained with reference to FIG. 8. Here, in the top view, a series of locking members 18 to 21 are shown from the frame opening side, and in b), it is shown as a pseudo-turned-over view from the outside. In FIG. 8 c), a perspective view of this series of locking members is shown. In principle, it is preferable that all the locking members have the same configuration. Here, the locking members 18 and 21 that are completely arranged on the outside are slightly modified (compare the notch region 34). Otherwise, the housing provided within the frame will cause a collision at a certain specific rotational position. However, it is preferable that all the locking members 18 to 21 are the same (see FIGS. 9 and later).

[0048] Each locking member has two guide shafts 28 or guide pins that protrude in both directions. Here, the side facing the slat is formed such that there is a guide collar 29 having a cutout that extends in the axial direction with which the leaf portion 17 of the slat engages. However, alternatively, it is possible to omit such a guide collar 29, and on this side, it is possible to directly provide the pins 28 with axial holes or recesses for the respective bearing pins 8' to 11' of the associated slats. This recess has an internal structure that can insert the corresponding pins of the slat into this recess and fix them against rotation.

[0049] The two shafts 28 that protrude on both sides engage with corresponding bearing recesses at the through openings 27 on the sides of the frame opening. Therefore, the locking members are, so to speak, individually attached independently of the slat 8. This is important because when the slat 8 is damaged, the corresponding locking disks 18 to 21 must not fall off the frame in the same way. If they do fall off, the locking function will not be executed, and correspondingly, the diagnostic function will not be provided either.

[0050] The locking members 18 to 21 are formed as eccentric wheels and are formed with corresponding locking plates 30, 31 that extend perpendicular to the shaft 28. The shapes of these locking plates are selected such that only synchronized simultaneous rotation is possible without collision due to the locking of the front and rear locking plates. If one of the locking plates or one of the locking members 18 to 21 does not rotate simultaneously while the other locking members rotate, in either case, regardless of the starting position, at the latest after a full cycle (e.g., starting from the open state, closing, and opening again), the radially outer contour of the moving locking member will contact the outer contour of the non-moving locking member. This has the effect of locking by pseudo shape fitting. For this purpose, there is a first locking plate 30 having a sweeping area 32 and, on the opposite side, a low-sweeping area with a cutout 33. These first locking plates are all at the same axial height in adjacent locking members. For all starting positions where one of the slats fails, in order to ensure that locking occurs immediately or, at least, at the latest after one or two complete operating cycles, here there is a further second locking plate 31 having a lateral protrusion 35 on the side. This second locking plate 31 can push the adjacent non-simultaneously rotating locking plate during one cycle to change the rotational position, and then, at this changed rotational position, the first locking plate or otherwise the second locking plate will move into the locked state.

[0051] FIG. 9 shows a perspective view of the locking disks 18-21 according to a further exemplary embodiment. The shape can be seen more accurately here. The locking disk has a through opening in the form of a shaft hole 40, in which a contour part, here a flat flange 41, is present, and the flat flange 41 is used to compress the shaft member 8' of the slat inserted into this hole so that the locking disk is connected to the corresponding slat with respect to bidirectional rotation. Further, there is a circumferential flange 44 where a sliding web 43 is provided. The circumferential flange 45 extends into a corresponding recess in the frame, and the flange 44 provided on the opposite side of the disk extends into the through opening 27 in the partition wall 23. Thus, this type of flange is present not only on the side of the second locking plate 31 but also on the side of the opposite first locking plate 30. Here, this flange 40 is designed to be higher than the opposite flange. First, the high flange 45 is inserted into a suitable opening, and then the disk is inserted by the mobility or flexibility of the partition wall 23 until the opposite flanges 54 are clamped in their respective through openings 27, whereby the disks 18-21 are inserted into the enclosed space 22. The sliding web 43 makes it less susceptible to the influence of dust. Dust can accumulate especially in the region formed with a smaller radius provided between the sliding webs, and thus does not interfere with the rotational movement.

[0052] As described above, the first locking plate 30 has a sweeping area 32 on one side. The contour of this area is bounded by each of the two block areas 46, and the two block areas 46 are connected via a transition area 49 and two lateral areas 47 with a gradually decreasing radius. These two lateral areas 47 are connected by a cut-in area 48, and the cut-in area 48 is indicated by reference numeral 33 in relation to FIG. 8.

[0053] In the following plane, directly adjacent to the first locking plate 30, there is a second locking plate 31. Here, there is a circumferential cylindrical region 50 with a small radius provided in the sweeping area of the first locking plate 30. In order to reduce weight or avoid distortion during manufacturing, a recess 42 can be provided in the cylindrical region 50. On the opposite side of this cylindrical region 50, there is also a sweeping area having the laterally protruding portion 35 already described above. In the sweeping area, in both cases, these two protruding portions 35 are first connected through a concave transition region 52 and a convex block region 51 located therebetween. Regarding the cylindrical region 50, a concave second transition region 53 follows the laterally protruding portion 35. Both the first locking plate 30 and the second locking plate 31 contribute to locking, but the first locking plate 30 is also used, in particular, to move a disk that does not operate together during the cycle to a position where locking can occur in a further operating sequence.

[0054] The locking function of the disks 18 - 21 can be described with reference to FIGS. 10 - 17.

[0055] The starting point in each case is the normal position. This is shown from the side of the first locking plate 30 in FIG. 10 and from the side of the second locking plate 31 in FIG. 11. Three normal positions of closed (0°), semi - open (42.2°), and open (85°) are shown. In each of these positions, the disks do not contact each other. The minimum distances are 0.1 mm - 5 mm, or 3 mm, or 0.5 mm respectively.

[0056] Next, FIG. 12 shows what happens starting from the closed position (0°) when there is a defect in the lowermost slat and the corresponding disk 55 does not rotate simultaneously. As shown in FIG. 12 a), here the disk viewed from the side of the first locking plate 30 starts to rotate counterclockwise (refer to the arrow) for opening. At a position of about 12° (refer to FIG. 12 b), the lateral region 47 of the disk adjacent to the disk 55 is already in a blocked state of contact with the block region 46 of the faulty disk 55.

[0057] Thus, so to speak, immediately, a block occurs after only a 12° rotation. The same sequence of steps is shown in c of FIG. 12 as seen from the side of the second locking plate 31. Here, the disk rotates in the corresponding clockwise direction.

[0058] FIG. 13 shows what happens when the disk rotates in the direction of the closed position starting from the open position (85°). Here too, a) and b) of the figure are shown from the side of the first locking plate, and c) and d) of the figure are shown from the side of the second locking plate. Here too, the lowermost disk 55 is not functioning. Here, a block occurs after the upper three disks have rotated approximately 42°.

[0059] Here, one of the block regions 51 of the lowermost disk comes into contact with one of the lateral protrusions 35 of the second disk from the bottom, and thus the upper three disks are blocked. Thus, starting from the open position, it is inevitable that a blocked state will already occur after passing through less than a quarter of a cycle. Thus, here too, a diagnostic block occurs very rapidly.

[0060] FIG. 14 shows what happens when rotating from the semi-open position (42.5°) to the closed position (0°), as seen from the side of the first locking plate. In FIG. 15, the same is shown from the side of the second locking plate. As can be seen in the transition from a) to b), initially nothing happens until the closed position (0°) is reached. The lower disks simply do not rotate simultaneously. Next, when the upper disks rotate in the reverse direction again (see c of the figure), at approximately 45°, the lateral region 47 of the second disk from the bottom comes into contact with the corresponding lateral region 47 of the lowermost disk, and when the open position is reached (see d of the figure), the lowermost disk is rotated by pushing it to another rotational position.

[0061] Also, when the upper three disks rotate again in the direction of the closed position, since the lateral protrusion 35 of the second disk from the bottom blocks the block region 51 of the lowermost disk 55, locking occurs again at approximately 40° (see e in the figure).

[0062] Finally, importantly, FIGS. 16 and 17 show the behavior of the disks when starting from the semi-open position (42.5°), first rotating towards the closed position, and the lowermost disk 55 does not rotate simultaneously.

[0063] Here, after reaching a position of approximately 45°, the lowermost disk comes into contact with the adjacent lateral region 47 (see b in the figure) and is pushed towards the semi-open position (see c in the figure), and thus starts to rotate simultaneously immediately. Here, when rotating in the opening direction together with the upper three disks, the lowermost two disks are also locked via the protrusion 35 and the block region 51 (see d in the figure).

[0064] Therefore, as a result of the disk shape, it is ensured that it is not necessary to go through more than one full cycle until the block is reliable, whereby a larger torque is measured on the disk drive motor, and thus diagnosis regarding the operating state of the slat package becomes possible via the motor.

[0065] FIG. 18 shows a further exemplary embodiment of a radiator shutter with five slats here. In a perspective view from the motor 12, the attachment of the slats can be seen. The motor directly drives the rightmost slat, i.e., slat 11a, at its axis of rotation, and the four subsequent slats arranged further to the left rotate simultaneously via the connecting rod 7 in the same manner as in the exemplary embodiments already described when the motor rotates the first slat 11a. The closed position is shown. Here, for the purpose of illustration, the entire radiator shutter is arranged on the mounting plate 68. The radiator shutter is usually mounted in the housing in a component connected upstream of the prime mover.

[0066] A locking housing 67 is provided on the opposite side of the motor 12. In the locking housing 67, bearing pins are attached on the side opposite to the drive side of the slats 8 - 11a. In Fig. 19 a), in this locking housing 67, the cover plate 69 has been removed (refer to the exploded view according to Fig. 19b), providing a view into the locking housing 67. In the locking housing, here, a locking rod 61 extending in a transverse direction with respect to the plane of the slats can be seen. This locking rod can be displaced only parallel to the plane covered by the axis of the slats and perpendicular to the extending direction of the slat axis in the housing 67.

[0067] At the height of each slat, there are locking recesses 64 extending in the direction of the main extension of the vertical and locking rod 61. Engagement pins 63 engage with these locking recesses 64. These engagement pins 63 are arranged on the rotating plate 60. These rotating plates 60 have storage openings 70. The rotating plate 60 is pressed against the bearing pins of the slats by this storage opening 70 and fixed against rotation. In these rotating plates 60, the engagement pins 63 are in all cases arranged eccentrically with respect to the rotation axis of the slats, and the rotating plate 60 rotates simultaneously with the slats as a result of, for example, a form - fit connection between each bearing pin 77 and each storage opening 70.

[0068] All the rotating plates 60 are aligned with the engagement pins 63 in the same direction. In each rotating plate 60, the engagement pin 63 points in the direction from the slat towards the locking rod 61.

[0069] To improve the guidance of the locking rod 61, the locking rod 61 has parallel slots 74 extending along the main extension direction between the locking recesses 64 of the engagement pins 63. Guide pins 75 provided on the rear wall of the housing slide in these slots 74.

[0070] A lower guide web 72 is provided on the lower wall of the housing, and the locking rod 61 is held between this upper housing wall 73 and the guide web 72 and can only displace along the displacement direction shown in FIG. 20 and the opposite direction thereof. However, the locking rod 61 can displace freely in this one direction within this housing.

[0071] Here, FIG. 20 shows how various components move relative to each other when all the slats are intact and not damaged. The top 0° indicates the closed state, and the leftmost slat is driven by a motor. Then, when the slat rotates to the 30° open position, the guide pin 63 moves upward counterclockwise in synchronization, drawing a quarter circle to the fully open position. At 30°, it only displaces slightly in the displacement direction 76, but at 45° and during further rotation from 60° up to 90°, the locking rod 61 advances in the displacement direction 76. During closing, the same thing happens in the reverse direction, that is, the engaging pin 63 draws a quarter circle in the clockwise direction. The locking rod 61 advances in the left direction in this figure during the movement from 0° to 90°, and the engaging pin 63 moves from the bottom position to the top position of the corresponding locking recess 64.

[0072] Here, in FIG. 21a, the starting situation when the slat 11a, that is, the rightmost slat, is damaged is shown. Starting from the fully closed position at 0° shown here, the engaging pins 63 are respectively positioned in the lower end region 66 in the locking recess 64. The lower end region 66 forms a kind of stop, but is usually not reached.

[0073] Here, as shown in b of FIG. 21, although the slat package is rotated via a motor, if the damaged slat 11a does not rotate simultaneously, the engagement pin 63 of the intact slat moves upward within the locking recess 64 and begins to advance the locking rod 61 to the left. Here, since the damaged slat 11a shown on the far right does not rotate simultaneously, its engagement pin 63 remains at the very bottom of the end region 66 of its locking recess 64, and the circumferential region on the right side of the engagement pin is pinched and contacts the inner contour of the locking recess just below the holding depression 65. As a result, the locking rod 61 cannot be displaced further to the left here. Therefore, the engagement pins 63 of the slats arranged further to the left are also prevented from further rotation, and consequently, the corresponding slats are also prevented from further rotation. Thus, the motor 12 is blocked, and as a result, it is detected that the slat is damaged.

[0074] This locking functions when starting from the fully closed position and reaching a deflection angle of approximately 11.3°, as shown in c of FIG. 21. In other words, as long as the damaged slat is located in the range of 0° to approximately 11° as the starting position, locking occurs as shown in b and c of FIG. 21.

[0075] Also, as can be seen in FIG. 22, when starting from a starting position of 30°, the damaged slat remains in this position and is held, so to speak, in the holding depression 65. Then, the slat shown at 45° further to the left cannot rotate simultaneously, and thus, the entire slat package is blocked.

[0076] FIG. 23 shows the situation of the entire package when starting from the closed state with the rightmost slat, i.e., slat 11a, damaged, as already described above. Here, the slat package can only rotate up to the position of 15° shown in the lower figure at most. This is because at this position, further displacement of the locking rod to the left is blocked by the engagement pin 63 of the rightmost slat 11a.

[0077] Figure 24 shows the situation starting from the fully open position where the rightmost slat, i.e., slat 11a, is damaged. Here, all the slats, including the damaged one, rotate simultaneously until the fully closed position of 0°. Only when the package is reopened during the next opening operation, as described in relation to Figure 23, the system is blocked at 15°.

[0078] Figure 25 shows the situation when the slat package is closed starting from the semi-open position of 45° (topmost figure). Here too, initially, the damaged slat is advanced to the closed state (0°), and only when the slat package is reopened again, as already described in relation to Figure 23, the damaged slat 11a locks the system at 15°.

[0079] Finally and importantly, Figure 26 shows the situation where the slat package is further opened starting from the semi-open position, here 42.5°. Here too, first, the leftmost damaged slat 11a is advanced to the fully open position, and here too, it reaches the locking position shown in the bottommost figure of Figure 26 only when it is fully closed or at least closed to the position of 30° and then reopened.

[0080] Figure 27 shows an alternative form of the locking rod 61. Figure 27a) shows a side view of an embodiment in which the locking recess 64 is not formed as a simple vertical slot with a lateral holding recess 65. Here, the locking recess 64 has a lateral offset portion 79 between a lower end region 66 and an upper end region 78. The offset portion 79 has the same effect as the holding recess 65 when the slat stops at 0° (see Figure 21), and has a similar effect to the holding recess 65 when the slat stops at 30° (see Figure 22). The advantage of a design with a lateral offset portion 79 is, firstly, that the engagement pin 63 is always laterally guided within the slot-shaped guide of the locking recess 64 without play. A further advantage is that, when comparing with the situation of Figure 22 for illustration purposes (where a corresponding locking recess with an offset portion has to be imagined), depending on the height of the offset portion, starting from the block of the slat at 90° or 45°, during an attempt to rotate the slat further in the 0° direction, locking and corresponding feedback of malfunctions to the motor also occur.

[0081] A further alternative form of the locking rod 61 is shown in Figures 27b and c. It may be advantageous for the locking recess 64 to be open at the top or bottom so that the slat can be inserted following the insertion of the locking rod 61 (see also Figure 28). In that case, the open side is closed by a further component (a cover in Figure 28). In addition, it is not necessary to configure the locking recess 64 as a through-opening. The locking recess 64 can also be formed as a groove, i.e., on the side not facing the slat, the locking rod 61 has a closed rear wall 81 or a groove bottom. This can be advantageous, especially when the locking recess 64 is open on one side, for reasons of stability.

[0082] Figure 28 shows a further radiator shutter with locking members. In this case, two slat packages are driven and controlled via a motor 12 arranged centrally. Here, the frame 2 has a vertical intermediate web 3 which is used not only for the attachment of the slats already described above but also for housing the motor 12. In contrast to the example described above, the slats do not extend over the full width of the frame. Instead, two individual slat packages are arranged in two recesses provided on the sides of the vertical intermediate web. The first group of slats 86 is arranged in the left-hand region shown, and the second group of slats 87 is arranged in the right-hand region shown.

[0083] The motor 12, which is arranged so as to be protected behind the vertical intermediate web 3 in the direction of movement, drives the two slat packages 86 / 87 together in synchronism. This is done by the motor driving the slats or the transmission shaft 85 (see the following description), and further slats moving via a common connecting member 7. For this purpose, the connecting member 7 has two connecting regions 83 and a bridging region 84 located therebetween. The locking members already described above are also provided here, in the form of respective locking rods 61, on the outside of the frame via respective rotary plates 60 provided on the respective slats 86 / 87. An eccentric engagement pin 63 is fixed to the rotary plate 60 or the rotary plate 60 is formed as an integral part with the eccentric engagement pin 63. These engagement pins 63 engage in the grooves of the locking rods 61. This locking rod 61 is the locking rod 61 already described above in connection with FIGS. 27 b) and c). In other words, this locking rod 61 has an open upper side of the groove or, more preferably here, a locking rod 61 which is open towards the rear in the direction of movement. This design enables the frame to be installed, so to speak, from the rear. This is done by first inserting the locking rod 61, then inserting the slats and finally closing via a cover 82 which is fixed, for example, by the screws shown. Also here, the locking rods are mounted so as to be displaceable only along the main direction of extension.

[0084] In the case of such a slat package with a relatively large number of slats, for reasons of weight and to maximize the flow cross-section when the slats are open, slats of a thin configuration are preferred. This can lead to insufficient torsional stability of the slats if a slat fails and becomes blocked. In this case, since the slats can simply be rotated by a motor, even if the rotation of the slats is blocked on the side not facing the motor, this blockage is not transmitted to the motor side and thus may not be transmitted as feedback to the motor.

[0085] In this exemplary embodiment, this problem is solved by the presence in the frame 2 of respective horizontal intermediate webs 88 provided at the same height as the slats. At the vertical height of this intermediate web 88, and protected behind the intermediate web 88 on both sides of the frame, there is a transmission shaft 85 that has sufficient torsional stability, rather than a slat. This transmission shaft 85 is similarly connected to the locking rod 61 in the same way as the slats, and when a blockage occurs via the locking rod 61, this transmission shaft 85 is also blocked. Further, this transmission shaft 85 is, in particular, connected to the motor 12 and is also a member that actuates the connecting rod 7. In that case, direct feedback is returned to the motor when a blockage occurs. If the transmission shaft 85 is connected to the motor not directly but via the connecting rod 7, the feedback is effected indirectly via this connecting rod 7. However, proper safeguarding of the feedback can also be done in another way, for example, by specially forming one slat with respect to torsional stability.

[0086] Figure 28b) shows in detail the configuration of the side where the rotating plate 60 of the slat 87 is arranged in the details related to the details of a). The rotating plate 60 is formed as an integral part with the slat 87 in this example and is connected to the slat 87 via a bearing pin 89. Each engaging pin 63 is provided eccentrically on each rotating plate 60.

[0087] Figure 28 c) shows the detailed configuration of the side portion of the slat 86 that is connected to the motor 12 in the details related to the details of a). The bearing pin 89 is arranged on the shaft and attached to the corresponding recess in the vertical intermediate web 3 of the frame 2. Each connecting pin 26 that engages with the corresponding recess in the connecting rod 7 is provided via a connecting lever 25. Here too, the connecting lever and the connecting pin are formed as an integral part with the slat.

[0088] Figure 29 d) shows a locking rod 61 having a locking recess 64 in the details related to the details of a) of Figure 28. The locking recess 64 is formed in this figure such that the rear portion is open by an insertion opening 80, and as described above, it has a lateral offset portion 79 approximately in the middle. A cover 82 is attached to this locking rod 61 and then connected to the frame. The cover 62 has a rear wall 90 that guides the locking rod 61 and a cover wall 91 that closes the upper insertion opening 80 when the cover is attached and fixed to the frame. On the front wall of this cover facing the slat, there is a contour portion 92 here, and each of the contour portions 92 is provided with a recess 93 for the bearing pin 89. Behind the contour portion 92, the rotating plate 60 of the slat is held. Due to these contour portions, when the slat is damaged, the area of the corresponding bearing pin 89 between the actual slat and the rotating plate 60 is damaged. Therefore, even if there is a damaged slat, it is ensured that the rotating plate remains within the frame and the connection to the locking rod 61 is guaranteed. Without this means, the slat may be damaged together with the rotating plate, and thus, since the rotating plate does not rotate simultaneously, there is a possibility that locking cannot be performed via the locking rod 61.
