Description

Locking device of a wheelhouse in a transport position, wheelhouse subassembly and wheelhouse having such a locking member, and method of positioning this locking member on a wheelhouse

The present invention relates to the field of wheelhouses of wiping mechanisms, in particular for a motor vehicle, and more particularly to the locking of these wheelhouses in a transport position. More specifically, the present invention relates to a locking member of a wheelhouse comprising at least one crank and at least one connecting rod in a transport position. The present invention also relates to a wheelhouse subassembly and to a wheelhouse having such a locking member, and also to a method of placing such a locking member on a wheelhouse.

Motor vehicle wiper linkages are hinged systems in different locations. This articulation is necessary for the proper functioning of the wiping system once the wheelhouse is installed on the motor vehicle. However, such an articulation presents problems in particular for the transport of this wheelhouse and for the installation thereof on the motor vehicle. Thus, it is necessary to limit the degrees of freedom of the wheelhouse both during transport and during installation.

Locking elements are known which make it possible to connect the connecting rod to bearings allowing the wheelhouse to be attached to the motor vehicle so that the wheelhouse is in a transport position. The locking elements known in the prior art can be in different forms, such as for example in the form of a clamp, in order to ensure the locking of this wheelhouse in a transport and installation position, that is to say ie a position in which any movement of a bearing of the wheelhouse with respect to the connecting rod is prevented.

However, these blocking elements described in this document are for single use and are removed, by cutting for example, after installation of the wheelhouse on the motor vehicle. Thus, it is necessary to use tools, generally cutting, in order to be able to free the wheelhouse. Furthermore, such blocking elements generate debris which will have to be treated subsequently, which generates additional costs.

The present invention aims to at least partially overcome the drawbacks of the prior art set out above.

Another objective of the present invention, different from the previous objective, is to provide a locking element for a wheelhouse of a wiping mechanism, in particular for a vehicle, which can be removed without requiring tools.

Another object of the present invention, different from the previous objectives, is to provide a blocking element which can remain on the wheelhouse of the wiping mechanism, once it is installed, so as to reduce the production of waste to be treated.

Another objective of the present invention, different from the preceding objectives, is to propose a blocking element which is simple to install on a wheelhouse of a wiping mechanism.

Yet another object of the present invention, different from the previous objectives, is to provide a locking element which allows simple release of the wheelhouse from the wiping mechanism.

The locking member locks the wheelhouse in the transport position by blocking the relative position between the connecting rod and the crank. Advantageously, the blocking member is installed on the connecting rod and on the crank without requiring the use of tools. Furthermore, the release of the wheelhouse is also carried out without requiring the use of tools.

The first housing is arranged near the second end of the crank and the second housing is arranged near the ball joint.

At least the first housing or the second housing has a narrowed opening leading to a circular opening, said narrowed opening being less than the diameter of the elastic axis of the locking member so as to block the elastic axis inside this circular opening.

Alternatively, the narrowed opening has two converging chamfers on either side and leading to the circular opening so as to facilitate the insertion of the elastic axis into the circular opening and to block the elastic axis at inside this circular opening.

According to this variant, the converging chamfers define a convergent insertion channel for the elastic axis.

At least the first housing or the second housing has a slot intended to cooperate with the elastic axis of the locking member in a reversible manner.

• insertion of the elastic axis in the first housing, • rotation of the connecting rod around the ball joint in order to place the wheelhouse in the transport position, • passage of the second protuberance between the crank and the connecting rod, and • insertion of the elastic axis in the second housing in order to maintain the relative position of the fixed rod relative to the first end of the crank when the wheelhouse is in the transport position, the first protrusion protruding from the crank and being in contact with a face of the crank opposite to that disposed opposite the connecting rod, and the second protrusion protruding from the connecting rod and being in contact with a surface of the connecting rod opposite to that disposed opposite the crank.

The locking member is removed from the second notch to release the wheelhouse by pressing the second protrusion.

The second protuberance comes into contact with the second face of the crank opposite the connecting rod when the locking member is removed from the second notch.

Advantageously, the blocking member remains on the wheelhouse at the level of the crank after its release.

Alternatively, the locking member is removed from the crank after release from the wheelhouse.

The following embodiments are examples. Although the description refers to one or more embodiments, this does not necessarily mean that each reference relates to the same embodiment, or that the characteristics apply only to a single embodiment. Simple features of different embodiments can also be combined or interchanged to provide other embodiments.

In the following description, reference is made to a first and a second side of the wheelhouse, to a first and a second end of the crank, to a first and to a second side of the crank, to a first and a second connecting rod surfaces, first and second protrusions, first and second housings, and first and second linkage subassemblies. It is a simple indexing to differentiate and name similar but not identical elements. This indexing does not imply a priority of one element over another and one can easily interchange such names without departing from the scope of this description. This indexing also does not imply an order in time for example to assess the arrangement of the wheelhouse on the motor vehicle, its operation, or its installation, or even to assess the shape of the locking member or its installation. on the wheelhouse to keep it in its transport position.

In the following description, the term “transport position” means in particular a position in which at least one end of the connecting rod and a crank to which this end of the connecting rod forms a minimum angle, more precisely at least this end of the connecting rod is in a position close to the bearing on which the crank is articulated so that the wheelhouse has minimal bulk when it is in its transport position.

Referring to Figures 1 to 4, there is shown a wheelhouse 7 of a wiping mechanism of a motor vehicle. The wheelhouse 7 comprises a first sub-assembly 9 (better visible in FIGS. 2 and 3), a second sub-assembly 9 ', and in addition a motor 71 configured to allow the displacement in translation of a connecting rod 3 connecting the first 9 and second 9 'subsets.

The first 9 and second 9 ’sub-assemblies each include a bearing 91 and a crank 5 articulated on the bearing 91.

The crank 5 has a first end 53 connected to the bearing 91, by a pivot link for example, and a second end 55 carrying a ball joint 57. On the other hand, one end of the rod 3 is connected to this ball joint 57 of so as to allow the articulation of the connecting rod 3 on this ball joint 57. Furthermore, the crank 5 has a first face 5a opposite to a second face 5b arranged opposite the connecting rod 3. Similarly, the connecting rod 3 has a first surface 3a opposite to a second surface 3b disposed opposite the crank 5.

When the wheelhouse 7 is in the transport position, the relative position of at least one end of the connecting rod 3 is kept fixed relative to the crank 5 of the first 9 or of the second 9 ′ subassembly using a locking device 1.

Referring to Figure 4, there is shown in more detail the locking member 1. The locking member 1 comprises a first protrusion 11, a second protrusion 13, and an elastic axis 15 connecting the first 11 and the second 13 growths between them. This locking member 1 cooperates with a first housing 51 formed in the crank 5 and a second housing 31 (visible in FIG. 3) formed in the connecting rod 3 in order to maintain the first sub-assembly 9 for example in the transport position of the wheelhouse 7. More particularly, the elastic axis 15 is arranged to pass through the first 51 and second 31 housings. As can be seen in FIG. 3, the first housing 51 is disposed near the second end 55 of the crank 5 and the second housing 31 is disposed at the connecting rod 3 near the ball joint 57.

The first 51 and second 31 housings are arranged opposite one another with respect to the central axis A (visible in particular in FIG. 2) of the connecting rod 3 when the wheelhouse 7 is in the transport position . In fact, with such an arrangement of the first 51 and second 31 housings, the blocking member 1 tends to bring the crank 5 and the rod 3 closer together by elastic effect and maintains the distance between these first 51 and second 31 fixed housings, so as to reversibly freeze the relative position of the connecting rod 3 relative to the first end 53 of the crank 5.

Furthermore, as visible in FIG. 3, the first housing 51 and / or the second housing 31 have a narrowed opening 58 which has two chamfers 60 converging towards the center of the crank 5 thus defining a convergent channel for inserting the blocking member 1 and more particularly of the elastic axis 15. The converging channel opens onto a circular opening 59. Thus, the elastic axis 15 of the blocking member 1 can be blocked inside this circular opening 59 The blocking of the elastic axis 15 inside the circular opening 59 allows the blocking member 1 to remain on the wheelhouse 7 after release of the first sub-assembly 9 for example, which makes it possible to reduce the waste generated during the installation of this wheelhouse 7 on the motor vehicle. On the other hand, one of the first 51 or second 31 housings has a U-shaped slot 33 (visible in FIG. 3) intended to cooperate with the elastic axis 15 of the locking member 1 in a reversible manner so that the locking of the wheelhouse 7 in the transport position is reversible.

According to the particular embodiment of Figure 1, the wheelhouse 7 has a first side 7a and a second side 7b. According to this embodiment, the first sub-assembly 9 is arranged on the first side 7a and the second sub-assembly 9 ’is arranged on the second side 7b. The motor 71 is installed on the second side 7b of the wheelhouse 7. Furthermore, only the first sub-assembly 9 comprising the locking member 1 is disposed on the first side 7a. According to this embodiment, an arrow M indicates the movement of the first end 53 of the crank 5 towards the connecting rod 3 during the positioning of the locking member 1. The second side 7b of the wheelhouse 7 generally corresponds to the driver side of the motor vehicle once the wheelhouse 7 is installed on the motor vehicle. According to a variant, the second side 7b can correspond to the passenger side of the motor vehicle once the wheelhouse 7 is installed thereon.

According to another embodiment not shown here, the first 9 and second 9 'sub-assemblies each have a blocking member 1 maintaining the relative position of each end of the rod 3 fixed relative to the first end 53 of the crank 5 carried by the first 9 and the second 9 'sub-assemblies. Thus, the first side 7a and the second side 7b of the wheelhouse 7 are locked in the transport position.

According to yet another embodiment, not shown here, only the second sub-assembly 9 ′ has the locking member 1. Thus, only the second side 7b of the wheelhouse 7 is locked in the transport position.

Advantageously, blocking the articulation of the connecting rod 3 on the ball joint 57 makes it possible to facilitate the transport of this linkage 7 by removing degrees of freedom of movement of certain parts of the linkage 7 and by blocking the linkage 7 in a position with minimal bulk. Furthermore, the blocking of this articulation also makes it possible to facilitate the installation of this linkage 7 on the motor vehicle by blocking in particular the articulation of the connecting rod 3 on at least one of the ball joint connections 57 carried by each of the cranks 5 of the first 9 and second 9 'subsets.

In the case where the wheelhouse 7 has a locking member 1 disposed at each end of the connecting rod 3, the second sub-assembly 9 'also has a narrowed opening 58 and a slot 33 arranged for one or the other on the crank 5 or on the connecting rod 3 as described above.

Referring again to FIG. 4 showing the blocking member 1 in detail, the first 11 and second 13 protuberances are configured to keep the blocking member 1 in place when the latter blocks the connecting rod 3 and crank 5 in the transport position. In order to facilitate the installation of the locking member 1 and the release of the linkage 7, at least one of the protrusions 11, 13 has a height H less than the spacing H 'between the crank 5 and the connecting rod 3 ( visible in Figure 6).

According to the particular embodiment of Figure 4, the first 11 and second 13 protuberances are made at least of an elastic material. Advantageously, in order to improve the resistance of the blocking member 1 to the various stresses, in particular of torsion and shear, which it can undergo and also in order to accelerate the process of manufacturing this blocking member 1, the first 11 and second 13 protuberances and the elastic axis 15 are made of material. Furthermore, the blocking member 1 is ideally made of carο rubber because this material is inexpensive and has elasticity and resistance properties, especially in tearing, suitable for the use of the blocking member.

1.

According to another embodiment not shown here, the first 11 and second 13 protuberances are made of a rigid material, that is to say having no elastic properties.

According to the particular embodiment of Figure 4, the elastic axis 15 has a cylindrical shape. The use of a cylindrical shape for the elastic axis 15 makes it easier to insert it inside the narrowed opening 58 and good cooperation with the circular opening 59. Furthermore, the use of a shape cylindrical for the elastic axis 15 also makes it possible to facilitate the cooperation of this elastic axis 15 with the slot 33. According to the particular embodiment of FIG. 3, in order to maintain the locking member 1 inside the circular opening 59, the narrowed opening 58 is less than the diameter D ′ of the elastic axis 15 of the locking member 1. Furthermore, the circular opening 59 has a diameter at least equal to the diameter D of the axis elastic 15, but less than a diagonal of the protrusion 11, 13 carrying the end of the elastic axis 15 cooperating with the circular opening 59 so that this protrusion 11, 13 cannot pass through this e circular opening 59.

Furthermore, according to the particular embodiment of Figure 4, at least one of the first 11 and second 13 protrusions has a cylindrical shape. According to this particular embodiment, the first 11 and the second 13 protuberances have a cylindrical shape. Advantageously, at least one of the protrusions 11, 13, or even both, has at least one dimension among the height H or the diameter D less than the spacing H '(visible in FIG. 6) between the crank 5 and the connecting rod 3 The use of a height H or a diameter D less than the spacing H 'between the connecting rod 3 and the crank 5 makes it easier to install the locking member 1 on the wheelhouse 7 when this this is in the transport position. Furthermore, the release of the wheelhouse 7 can be facilitated by the use of such dimensions for the height H or the diameter D because the first 11 or the second 13 protrusion can pass between the connecting rod 3 and the crank 5 during the release of the wheelhouse 7 as shown with reference to Figure 6.

π

Referring to Figures 5A and 5B, there is illustrated a method of positioning the locking member 1 on the first sub-assembly 9 of Figure 3 in order to lock the wheelhouse 7 in the transport position.

Referring to FIG. 5A, the method comprises a step a of inserting the elastic axis 15 into the first housing 51 in order to install the locking member 1 at the level of the crank 5.

The method then implements a step b of rotation of the connecting rod 3 around the ball joint 57 in order to place the wheelhouse 7 in the transport position, then a step c of passage of the second protrusion 13 between the crank 5 and the connecting rod 3. According to a variant, these two steps b, c can be reversed. According to this variant, a step of traction on the second protrusion 13 along the crank 5 is carried out in order to bring the first protrusion 11 into contact with a first surface 5a of the crank 5 disposed opposite to a second face 5b disposed opposite the connecting rod 3. The connecting rod 3 is then rotated to be placed in the transport position while maintaining traction on the second protuberance

13.

Referring to FIG. 5B, the method then comprises a step d of inserting the elastic axis 15 into the second housing 31 in order to maintain the relative position of the connecting rod 3 fixed relative to the first end 53 of the crank 5 when the wheelhouse 7 is in the transport position. When the linkage 7 is locked in the transport position, the first protrusion 11 projects from the crank 5 and is in contact with the first face 5a of the crank 5 opposite to the second face 5b disposed opposite the connecting rod 3. By elsewhere, the second protrusion 13 projects from the connecting rod 3 and is in contact with the first surface 3a of the connecting rod 3 opposite to the second surface 3b disposed opposite the crank 5. The linkage 7 is maintained in the transport position by to the elastic stress exerted by the elastic axis 15 between the first 51 and second 31 housings.

Thus, the installation of the locking member 1 in order to maintain this wheelhouse 7 in the transport position is possible without requiring the use of tools.

Referring to Figure 6, there is shown the first sub-assembly 9 of the wheelhouse 7 once the connecting rod 3 released. In order to release the wheelhouse 7, the locking member 1 is removed from the second housing 31 by pressing on the second protrusion 13 in order to allow the exit of the elastic axis 15 from the second housing 31. Following this exit from the second protuberance 13, it comes into contact with the second face 5b of the crank 5. This displacement of the second protrusion 13 is possible due to the elastic return imposed by the elastic axis 15 in response to the extension undergone during the pushing step on the second projection 13 in order to extract it from the second housing 31. Furthermore, the operator carrying out the operation of installing the wheelhouse 7 on the motor vehicle can also pull on the first projection 11 in order to bring the second protrusion 13 into contact with the second face 5b of the crank 5 if necessary. Preferably, the wheelhouse 7 is released from the transport position once it is installed on the motor vehicle. In addition, the blocking member 1 remains in the first housing 51, and more precisely at the level of the circular opening 59 because the narrowed opening 58 prevents the natural passage of the elastic axis 15 and therefore the exit from the locking device 1.

Thus, the release of the wheelhouse 7 is possible in a simple manner and without requiring the use of tools. Indeed, this release is done only by pushing on the second protrusion 13 in order to remove this second protrusion 13 from the second housing 31. Furthermore, this release is simple and easy to implement.

Referring to Figure 7, there is partially shown the wheelhouse 7 installed on the motor vehicle, and more particularly the first side 7a of the wheelhouse 7. According to the particular embodiment of Figure 7, the wheelhouse 7 is fixed on the motor vehicle using fixing screws 73 configured to secure the bearing 91, and in particular a plate 93 carried by this bearing 91, to an element of the motor vehicle. Advantageously, the blocking member 1 remains on the wheelhouse 7 at the first housing 51 of the crank 5 after its release. Thus, the reuse of this blocking member 1 is possible if it is necessary to block this wheelhouse 7 in the transport position later. Furthermore, the fact that the blocking member 1 remains on the wheelhouse 7 after release of the latter makes it possible to limit the waste to be treated due to the installation of this wheelhouse 7 on the motor vehicle. The fact that the locking member 1 remains on the crank 5 following the release of the linkage 7 does not harm the operation of this linkage 7 because the second projection 13 has a height H less than the spacing H 'between the connecting rod 3 and the crank 5 on the one hand, and the wheelhouse 7 does not pass through its transport position during its operation on the other hand.

According to a variant not shown here, the blocking member 1 can be removed from the crank 5 after release of the wheelhouse 7. This removal of the blocking element 1 is carried out by extraction of the elastic axis 15 from the first housing 51 of the crank 5, and more precisely of the circular opening 59 of this first housing 51.

The embodiments described above are examples provided by way of illustration and not limitation. Indeed, it is entirely possible for those skilled in the art to adapt the geometric shape or the dimensions of the first 11 and second 13 protrusions as well as of the elastic axis 15 of the locking member 1 without going out of the framework of this description. Furthermore, those skilled in the art will be able to completely adapt the shape of the first 51 and second 31 housings in order to improve their cooperation with the elastic axis 15 without departing from the scope of the present description.

Thus, the reversible holding in place in a transport position of a wheelhouse 7 is possible thanks to the locking member 1 described above. Advantageously, the blocking member 1 is installed on the wheelhouse 7 without requiring the use of tools and the release of the wheelhouse 7 is also possible without using tools. Furthermore, the use of such a blocking member 1 makes it possible to limit the waste to be treated because it remains on the wheelhouse 7 after its installation on the motor vehicle. On the other hand, such a locking member 1 can allow the wheelhouse 7 to be locked again in the transport position if this proves necessary later.
