Description

Motor vehicle and blocking device for a storage compartment of a motor vehicle

Technical Field

The invention relates to a blocking device for a storage compartment of a motor vehicle. The invention further relates to a motor vehicle having a storage compartment and such a closure device.

Background

Motor vehicles often have a large number of storage compartments in which different items can be placed. Usually, such storage compartments are also equipped with a removable cover, so that they can be closed and opened when required. In particular, it is desirable in the event of an accident to keep such a storage compartment closed so that the articles accommodated in the storage compartment are not rolled up by the passenger compartment. In different countries there are also regulations that determine: such a cover must remain closed to the respective storage compartment in the event of an accident.

Disclosure of Invention

The object of the present invention is to provide a particularly simple and reliable solution by means of which a movable cover for closing a storage compartment can be kept closed if required.

The blocking device according to the invention for a storage compartment of a motor vehicle comprises a movable cover for closing the storage compartment. The blocking device furthermore has a blocking element and a longitudinal guide, by means of which the blocking element is guided in a linearly movable manner between a retracted release position, in which an opening movement of the cover is effected, and an extended blocking position, in which the opening movement of the cover is blocked. Furthermore, the blocking device according to the invention comprises a spring device which exerts a spring force on the blocking element as follows: the spring force holds the blocking element in the release position, wherein the spring force is smaller than a force acting on the blocking element in the direction of the blocking position, which force is obtained with a predetermined acceleration of the blocking element in the direction of the blocking position.

The longitudinal guidance is a positive guidance, by means of which it is possible to ensure: the blocking element can be moved translationally in one direction only, i.e. between a retracted release position and an extended blocking position. The spring device is designed in such a way that the spring force acting on the blocking element from which the blocking element is held in the release position is smaller than the force acting on the blocking element in the direction of the blocking position in the event of a predetermined acceleration of the blocking element. The predetermined acceleration is understood to be a specific threshold value which is determined for the acceleration of the blocking element along the longitudinal guide. The force resulting from the mass of the blocking element and the acceleration acting on the blocking element in the direction of the blocking position, at a predetermined acceleration of the blocking element in the direction of the blocking, is greater than the spring force acting on the blocking element by the spring device, wherein the spring force ensures that: the blocking element is held in the release position in other cases, i.e. as long as a predetermined acceleration of the blocking element in the blocking direction is not reached.

By varying the mass of the blocking element and the configuration of the spring device, it is possible to determine in a particularly simple and precise manner: when the blocking element is triggered, i.e. moved from the retracted release position into the extended blocking position, in which it blocks the opening movement of the cover. In the extended blocking position, the blocking element protrudes from the longitudinal guide to such an extent or even has already left the longitudinal guide that the opening movement of the cover is impeded by the blocking element. In the extended blocking position, at least a part of the blocking element comes into contact with the movable cover in such a way that the movable cover can no longer be opened. In this way, it is possible to ensure in a reliable manner, for example in the event of a crash of the motor vehicle: the movable cover reliably closes the storage compartment as long as it is in its closed position in the event of a collision.

It is irrelevant here for the blocking device according to the invention whether the displaceable cover is a pivotable cover or a linearly displaceable cover. The cover can thus be, for example, a pivotable flap, by means of which the storage compartment can be closed. Alternatively, however, it is also possible for the cover to be linearly movable, for example along a guide, between a position in which it closes the storage compartment and a position in which it releases the storage compartment. The storage compartment can be located, for example, in the region of a center console, in the region of an instrument panel, in the region of an armrest, or also, for example, on the inside of a door of a motor vehicle. By means of the blocking device according to the invention, it is possible to reliably ensure, at any time and regardless of the type of storage unit and the type of removable cover: the blocking element is moved autonomously or automatically into an extended blocking position in which the opening movement of the cover is blocked if a predetermined acceleration is exceeded. The blocking device is thus self-locking.

Advantageous embodiments of the invention provide for: the longitudinal guide at least partially encloses the blocking element in its retracted release position in the manner of a sleeve. A particularly reliable and precise longitudinal guidance of the blocking element can thereby be ensured by means of the longitudinal guide. For example, the longitudinal guide may be a bore in a vehicle-side carrier or in a carrier member, wherein the blocking element is embedded in the carrier member. Alternatively, it is also possible, for example, for the longitudinal guide to be constructed as a separate sleeve which at least partially encloses the blocking element in its retracted release position. Such a longitudinal guide configured as a sleeve can in turn be inserted into a vehicle-side opening suitable for this purpose, for example, a carrier component of a motor vehicle.

According to a further advantageous embodiment of the invention, provision is made for: the spring device has spring elements which act on the blocking element with a spring force transversely to the longitudinal guide. The spring elements are pressed, for example, in the radial direction against the blocking element, as a result of which they are held in the retracted release position and, more precisely, are held in the retracted release position until an acceleration force acting on the blocking element in the direction of the blocking position is achieved, wherein the acceleration force is derived with a predetermined acceleration of the blocking element in the direction of the blocking position. The blocking element can, for example, have a substantially cylindrical cross section, wherein the spring elements act on the blocking element, for example, from the outside in the radial direction with the spring force described, so that the blocking element is held in the retracted release position. The spring force to be exerted by the spring elements can be set particularly simply and precisely by providing a plurality of spring elements.

In a further advantageous embodiment of the invention, provision is made for: the spring means is a separate member that is slipped onto the longitudinal end of the blocking element, wherein the member is arranged between the blocking element and the longitudinal guide. In this case, the spring means is umbrella-like sleeved onto said longitudinal end of the blocking element, wherein the spring means is arranged between the blocking element and the longitudinal guide along the longitudinal guide with respect to a direction transverse to the provided direction of movement of the blocking element. For example, the blocking element can itself be a metallic component, for example a cast component, wherein the spring device can be an injection-molded component, for example. The complex geometry of the spring device can also be realized in a simple manner in large numbers by injection molding, so that, for example, undercuts or the like for precisely setting the holding force of the spring device can be realized in a particularly simple manner in the course of mass production. The blocking element then only has to be positioned on the spring device, in that the spring device is slipped onto said longitudinal end of the blocking element. The spring device and the blocking element then constitute a structural assembly which can in turn be inserted into the longitudinal guide in order to manufacture said blocking device.

According to an alternative advantageous embodiment of the invention, provision is made for: the spring device is configured as an integral part of the longitudinal guide. In other words, the spring means and the longitudinal guide constitute one and the same component in this case. By integrating the function of the spring device into the longitudinal guide, a component can be saved in the blocking device. For example, it is possible to manufacture the longitudinal guide as an injection-molded component together with the spring device integrated therein. If the longitudinal guide has a spring means, i.e. the longitudinal guide and the spring means are one and the same component, the assembly step, i.e. the insertion of the spring means into the longitudinal guide, can be eliminated. Instead, it is only necessary to insert the blocking element into the longitudinal guide, wherein in the installed position in a defined manner, the spring device then automatically exerts a corresponding retaining force on the blocking element, so that it is reliably held in the retracted release position as long as a predetermined acceleration is not exerted on the blocking element.

A further advantageous embodiment of the invention provides for: in the release position, the spring device bears in a form-fitting manner against the blocking element or the longitudinal guide and thereby holds the blocking element in the release position. In addition to the mere application of a spring force to the blocking element by the spring device, provision is preferably therefore also made for: the blocking element is held in the release position by a form fit between the spring device and the locking element or by a form fit between the spring device and the longitudinal guide. This ensures that: the blocking element is also reliably held in its release position in the event of vibrations which occur frequently during driving operation of the motor vehicle. In the case of a preferred embodiment, in which the blocking element is held in the release position not only by the spring force but also by a form fit, the predefined acceleration of the blocking element in the direction of the blocking position is selected to be so great that, in the event of the occurrence or exceeding of said acceleration, the holding force acting on the blocking element in the manner of the sum of the spring force and the form fit is exceeded, so that the blocking element is then moved from the retracted release position into the extended blocking position.

According to a further advantageous embodiment of the invention, provision is made for: the longitudinal guide is configured as a component of a carrier on which a cover for the storage compartment is mounted in a movable manner. In other words, it can thus be provided that: the longitudinal guide is an integral component of a vehicle-side carrier, on which a cover for the storage compartment is mounted in a movable manner. In this case, the spring device only has to be fitted to the blocking element, for which purpose the structural assembly formed by the spring device and the blocking element has to be simply inserted into the longitudinal guide of the vehicle-side construction. In this case, the longitudinal guide can be aligned in a particularly simple manner to the cover to be blocked if necessary. Since, in this preferred embodiment of the invention, the cover is mounted in a movable manner on the vehicle-side carrier.

Alternative advantageous embodiments of the invention provide for: the longitudinal guide and the blocking element inserted therein and held in the release position by means of the spring device form a structural assembly in the form of a sleeve which is fixed in a recess of a carrier on which a cover for a storage compartment is mounted in a movable manner. The longitudinal guide and the carrier are thus in this case two separate components. On the vehicle side, only bores or openings have to be provided in the region of the carrier, into which bores or openings the structural assemblies, which are designed in the form of a bush, are then inserted. The longitudinal guide is preferably fixed firmly in the recess of the carrier in such a way that, when a predetermined acceleration is reached or also exceeded, only the blocking element is guided along the longitudinal guide and the longitudinal guide is not removed from the recess of the carrier. This preferably ensures that: the longitudinal guide is pressed into the recess, fixed in the recess by means of a snap connection or screwed into the recess. Other fixation patterns are possible.

In a further advantageous embodiment of the invention, provision is made for: the cover has a recess which is arranged opposite the blocking element in a position of the cover which closes the storage compartment. As soon as the triggering condition for the blocking element is fulfilled, i.e. at least a predefined acceleration acts on the blocking element in the direction of the blocking position, the blocking element reaches into the recess of the cover and, more precisely, reaches such a way that the cover can no longer be opened and the compartment is reliably held closed. Irrespective of whether the cover now has a recess, the blocking element arranged in the extended blocking position and the cover always cooperate in a form-fitting manner such that the blocking element reliably blocks the opening movement of the cover.

The motor vehicle according to the invention comprises a storage compartment which is arranged in the region of a door trim panel of the motor vehicle and a blocking device according to the invention or an advantageous embodiment of a blocking device according to the invention. Alternatively or additionally, as already mentioned above, it is also possible to arrange the storage compartment together with the movable cover at different locations in the vehicle interior of the motor vehicle. The blocking device is always arranged in the region of the storage compartment and the associated cover in such a way that the blocking element of the blocking device reliably closes the cover, i.e., the opening movement of the cover is impeded as soon as a predetermined acceleration of the blocking element in the direction of the blocking position is reached or exceeded.

Detailed Description

Fig. 1 shows a motor vehicle 1 in a schematic plan view. In this and the following figures, the longitudinal direction of the vehicle is marked with x, the transverse direction of the vehicle is marked with y and the vertical direction of the vehicle is marked with z. A storage compartment 4, which is shown in a perspective view in fig. 2, is arranged in the region 2 of the driver's door 3 of the motor vehicle 1.

The storage compartment 4 can be arranged, for example, in the region 2 of a door trim panel of the motor vehicle 1. The storage compartment 4 can be released and closed by means of a rotatable cover 5. The rotatable cover 5 is mounted on a carrier 8 on the vehicle side by an arm 6 in a rotatable manner about a rotation axis 7. The carrier 8 may be, for example, a component of the driver's door 3.

In the present illustration, the rotatable cover 5 is shown in its closed position, in which it closes the storage compartment 4. The articles arranged in the storage compartment 4 are therefore not accessible in the vehicle interior in the position of the cover 5. By rotating the cover 5 in the direction indicated by the arrow 9, the storage compartment 4 can be released, so that a vehicle occupant can, for example, remove an item from the storage compartment 4 or also place an item into the storage compartment 4. The arm 6 has a recess in the form of an opening 10, which is part of a blocking device 12, not shown here, which serves to ensure that the closed cover 5 does not open if required, for example in the event of an accident in the motor vehicle 1.

Fig. 3 shows the storage compartment 4 and the rotatable cover 5 in a further perspective view, wherein a part of the rotatable cover 5 and a part of the carrier 8 are left free, so that the view to the longitudinal guides 11 arranged in the carrier 8 is released.

Fig. 4 shows a partial sectional side view of a storage compartment 4 with a rotatable cover 5. The individual elements of the blocking device 12 already mentioned are clearly visible in this illustration. The blocking device 12 comprises a cover 5 and a blocking element 13 for blocking an opening movement of the cover 5. The blocking device 12 furthermore comprises the already mentioned longitudinal guide 11, by means of which the blocking element 13 is guided in a linearly displaceable manner. The blocking element 13 can thus be moved between a retracted release position, which is shown here, and a blocking position, which is not shown here, and which projects partially from the longitudinal guide 6. In the retracted release position, the blocking element 13 effects an opening movement, i.e. a rotational movement, of the cover 5. In contrast, in the extended blocking position, which is not shown here, the extended blocking element 13 blocks the opening movement of the cover 5.

Furthermore, the blocking device 12 comprises a spring device 14 which, according to the present illustration, is pushed onto the blocking element 13 from the right, so that the blocking element 13 is arranged partially within the spring device 14 with respect to its main direction of extension. The blocking element 13 and the spring means 14 are fixed to each other. The spring device 14 acts a spring force directed radially outwards on the longitudinal guide 11. The blocking element 13 is thereby held in the release position shown here. This spring force is smaller than the acceleration force acting on the blocking element 13 in the direction 15 of the blocking position, which is obtained with a predetermined acceleration of the blocking element 13 in the direction 15.

As can be seen, the blocking element 13 with the spring device 14 fitted thereto is positively guided by means of the longitudinal guides 11 in the transverse direction y of the vehicle. The blocking element 13 can therefore be moved only in the transverse direction y of the vehicle. In the release position shown here, the blocking element 13 together with the spring device 14 is arranged so far away from the edge 16 surrounding the opening 10 that the cover 5 can be rotated without any problem counterclockwise according to the present illustration.

If a side impact, for example, now occurs, the blocking element 13 accelerates in the direction 15, i.e., in the transverse direction y of the vehicle. The holding force set by the spring device 14, which ensures that the blocking element 13 remains in the retracted release position shown here, is set here to a predefined acceleration value in the transverse direction y of the vehicle. As long as the acceleration value is not reached or exceeded, the spring device 14 holds the blocking element 13 in the retracted release position shown here, since the spring device 14 tensions itself and thus tensions the blocking element 13 in the longitudinal guide 11 in the radial direction.

As soon as the acceleration occurring in the transverse direction y of the vehicle reaches or exceeds this predefined acceleration value, the holding force exerted by the spring device 14 is no longer sufficient to hold itself, together with the blocking element 13 fastened thereto, in the retracted release position shown here. The blocking element 13 is thus moved further into the opening 10 in the direction 15. As a result, the blocking element 13 is moved into the engagement region of the edge 16. The closed cover 15 can then no longer be rotated counterclockwise according to the present illustration. In the extended blocking position, the blocking element 13 thus prevents an opening movement of the cover 5. In the event of a side impact of the motor vehicle 1, it can thus be ensured that the closed cover 5 also remains closed, so that the items arranged in the storage compartment 4 cannot reach into the vehicle interior.

In fig. 5, the blocking element 13 and the spring device 14 are shown only in a side view. As should be apparent, the spring device 14 is umbrella-like fitted over the longitudinal end of the blocking element 13, which is not further shown. The hook-shaped element 17 of the blocking element 13 is in this case passed through a corresponding opening 18 of the spring device 14, thereby fixing the spring device 14 on the blocking element 13.

The spring device 14 furthermore has a plurality of spring elements 19. These spring elements 19 are radially outwardly directed away from the blocking element 13. In the installed position of the blocking element 13 and the spring device 14 in a defined manner (as shown in fig. 4), the spring element 19 is pressed radially against the blocking element 13 and thus exerts the retaining force with which the blocking element 13 together with the spring device 14 is retained in the longitudinal guide 11. The spring element 14 is pretensioned in the position pressed against the blocking element 13 and exerts a spring force radially outward on the longitudinal guide 11. In the installed position in a defined manner, the respective radial projection 20 of the spring device 14 also bears on the inner side against the longitudinal guide 11.

In fig. 6, the spring device 14 is shown separately in a side view. The spring device 14 has overall four of the radial projections 20, by means of which the spring device 14 is radially centered within the longitudinal guide 11.

In fig. 7, the spring device 14 is seen in a partial sectional side view. In this illustration, the cavity 21 for partially accommodating the blocking element 13 is well visible. Furthermore, one of the two openings 18, through which the hook-shaped element 17 of the blocking element 13 is drilled, is to be seen in the present illustration, so that the blocking element 13 is secured to the spring device 14.

Fig. 8 shows the spring device 14 in a plan view. Here it is seen that: the spring device 14 has eight of the spring elements 19, which are arranged uniformly distributed in relation to the circumferential direction of the spring device 14. The four radial projections 20 and the two openings 18 are also clearly visible in the present illustration.

The blocking element 13 is shown separately in a side view in fig. 9. The blocking element 13 comprises two stops 22, on which the spring device 14 (as can be seen in fig. 5) is supported in the longitudinal direction of the blocking element 13. Furthermore, the two hook-shaped elements 17, which protrude outward from the central axis of the blocking element 13, which is not further marked, are also clearly visible in the present illustration. As soon as the spring device 14 is slipped over the hook-shaped element 17, the hook-shaped element 17 is moved radially inwards, and as soon as the hook-shaped element 17 has penetrated through the opening 18 of the spring device 14, a portion is again largely blocked radially outwards. The hook-shaped element 17 and the opening 18 thus form a snap connection, whereby the blocking element is fixed to the spring device 14.

Furthermore, the blocking element 13 has two cylindrical regions 23, 24 and a conical region 25. The pretension of the spring elements 19 of the spring device 14 can be set by the length of the conical region 25 and the degree of the inclined position of the conical region 25 relative to the cylindrical region 23. The holding force exerted by means of the spring element 19 can thereby be set. Furthermore, it is of course also possible to set by the material composition of the spring element 19: the spring means 14 exert what retaining force on the blocking element 13 in order to retain it in the retracted release position.

In fig. 10, the blocking element 13 is shown in a top view. It should now also be well seen how the two hook-shaped elements 17 and the two stops 22 are arranged.

In fig. 11, the blocking element 13 is shown in its installed position within the longitudinal guide 11 in a defined manner in a partially transparent side view. First, the spring means 14 is fitted over the blocking element 13. Subsequently, the structural assembly consisting of the blocking element 13 and the spring element 14 can be inserted into the longitudinal guide 11 through the outlet opening 26. For this purpose, a tool, not shown here, can be used, for example, in order to press the spring element 19, which in the unloaded state projects radially outward, radially against the blocking element 13, so that it can be introduced into the longitudinal guide 11 through the outlet opening 26.

In fig. 12, the blocking element 13 inserted into this longitudinal guide 11 is shown in a partially sectional side view. The longitudinal guide 11 has at least two different inner diameters, so that an annular undercut 27 is formed. The respective free end 28 of the spring element 19 is shaped in such a way that it surrounds the annular undercut 27. The free ends 28 of the spring elements 19 thus bear in a form-fitting manner against the annular undercut 27 of the longitudinal guide 11. This results in an easy braking of the spring element 19 within the longitudinal guide 11. As a result, an undesired sliding out of the blocking element 13 from the outlet opening 26, which could otherwise be caused, for example, in the event of vibrations occurring during operation of the vehicle, is prevented.

Furthermore, a support 29 is provided in the longitudinal guide 11, against which the end face 30 of the blocking element 13 rests. The bearing 29 is arranged in the axial direction in such a way that it is matched to the annular undercut 27 in such a way that the free end 28 of the spring element 19 surrounds the annular undercut 27 in a form-fitting manner when the blocking element 13 rests with its end face 30 on the bearing 29. In this way, the blocking element 13 with the spring device 14 fitted thereon can be positioned in the longitudinal guide 11 in a particularly simple manner. Since, as soon as the retracted release position of the blocking element 13 shown here is reached, the free ends 28 brake on the annular undercut 27 and fix the blocking element 13 together with the spring device 14 in said position.

In fig. 13, an alternative embodiment of the longitudinal guide 11 is shown, wherein the blocking element 13 is inserted in the longitudinal guide 11. The longitudinal guide 11 has spring means 14. In other words, in the present embodiment, the spring device 14 is configured as an integral part of the longitudinal guide 11. The spring means 14 and the longitudinal guide 11 are therefore not separate components. The longitudinal guide 11 and the blocking element 13 inserted therein and held in the release position shown here by means of the spring device 14 form a structural assembly in the form of a bushing, wherein the structural assembly can be inserted into a recess of the carrier 8, thus for example in the region 2 of the door trim panel. For this purpose, the longitudinal guide 11 can be pressed into the recess, for example in the region 2 of the door trim panel, fixed by means of a snap connection or screwed into the door trim panel.

In turn, a plurality of spring elements 19 are arranged uniformly distributed with respect to the circumferential direction. Between the individual spring elements 19, corresponding recesses 31 are provided. The width and length of the groove 31 in turn determine the length and width of the respective spring element 19. Depending on how wide and how long the recess 31 is selected, the spring force exerted by the spring element 19 can be determined, which spring force secures the blocking element 13 in the retracted release position shown here. The respective free end 28 of each spring element 19 furthermore bears in a form-fitting manner against the conical region 25 of the blocking element 13. This results in an easy braking, which is particularly impeded by vibrations occurring during driving operation: the blocking element 13 is removed from the longitudinal guide 11.

Fig. 14 shows an embodiment of the longitudinal guide 11 shown in fig. 13 in a side sectional view, wherein the blocking element 13 is arranged outside the longitudinal guide 11. In the present illustration, these two cylindrical regions 23, 24 and the conical region 25 of the blocking element 13 are again well visible. The blocking element 13 is simply inserted axially with its end face 30 forward into the longitudinal guide 11, and to be precise to the extent that: until the free end 28 of the spring element 19 surrounds the conical region 25 and at the same time the end face 30 of the blocking element 13 rests against the corresponding bearing 29 within the longitudinal guide 11.

In fig. 15, the blocking element 13 inserted into the longitudinal guide 11 is shown in a side view. As can be seen well in this illustration, the end face 30 of the blocking element 13 bears on the one hand against the spring-like support 29 and at the same time encloses the conical region 25 of the blocking element 13 with the free end 28.

The embodiment of the longitudinal guide shown in fig. 13 to 15 operates in principle analogously to the embodiment described in connection with fig. 4 to 12, the longitudinal guide 11 and the spring device 14 being constructed as separate components. In both cases, the spring element 19 exerts a predetermined retaining force, so that the blocking element 13 remains in the retracted release position, in which the opening movement of the cover 5 is effected, until a predetermined acceleration acts on the blocking element 13 in the transverse direction y of the vehicle, wherein the acceleration force of the blocking element 13 occurring here exceeds the retaining force of the spring element 19 to such an extent that the blocking element 13 moves autonomously into its extended blocking position, in which the opening movement of the cover 5 is prevented.

However, since the spring device 14 is part of the longitudinal guide 11 in the embodiment shown in fig. 13 to 15, the spring element 19 is not supported on the longitudinal guide 11 as in the embodiment shown in fig. 4 to 12 in order to fix the blocking element 13 in the retracted release position. Instead, the spring element 19 presses radially inwards and thus exerts a retaining force on the blocking element 13. The spring means 14 are also not moved into the blocking position together with the blocking element 13. Alternatively, the blocking element 13 can also be moved relative to the spring element 19 from the release position into the blocking position.

The longitudinal guide 11 may for example be a bushing which can be inserted into a recess of the carrier 8. In the inserted state into the recess, the spring element 19 has sufficient clearance in the radial direction to be able to bend the spring element 19 outwards to such an extent that the blocking element 13 can be removed from the longitudinal guide 11. This can for example ensure thereby that: the recess is made to have a larger diameter in the region of the spring element 19 than in the region of the right-hand side of the longitudinal guide 11. Alternatively, the recess may be configured, for example, as a blind hole in the carrier 8 and, for example, slightly shorter than the longitudinal guides 11, so that the spring element 19 is arranged outside the recess.

Irrespective of whether the spring device 14 and the longitudinal guide 11 are embodied as an integral component or in two parts, the described blocking device 12 is not limited solely to the pivotable cover 5 in the region 2 of the vehicle door. In other words, the blocking device 12 for releasing and blocking different covers, whether they be rotatable covers or linearly displaceable covers, can be used in the vehicle interior. With the described blocking device 12, it is possible to ensure, in particular in the event of an accident in the motor vehicle 1: the most different covers for closing the respective storage compartments in the vehicle interior are also reliably held closed, so that the contents contained in the storage compartments do not reach the vehicle interior.
