Definitions

• the present invention relates to a mechanical module, in particular for a key of a vehicle, and a key.
• Vehicle keys are generally known. They are intended for example to lock or unlock the opening of the vehicle, for example doors, control a tailgate, a lock and / or a starter of the vehicle.
• vehicle keys are known, in particular according to the French patent application FR 2,815,521 A1, which comprise a key body forming a housing for electronic means for remote locking means of the opening of the vehicle.
• the housing is often provided in two parts which each form about half of the housing.
• the housing can be provided so that both parts of the housing can be undone or so that both parts of the housing can not be undone without destroying or at least damaging the housing.
• the international patent application WO 2007/140119 A2 describes a car key with a housing, the housing being provided in two parts each forming about half of the housing, the parts being connectable to each other in such a way that a separation of the parts can be detected later.
• known keys comprise an insert mounted on the key body so as to be able to pivot about an axis of rotation, on the one hand, between a position of use, and on the other hand, a position storage
• the body of the key may have various shapes depending in particular on the desired aesthetic effect.
• a disadvantage of such keys is the need to have to open the key body when the battery inside the key body has to be changed. In such a battery exchange situation, having to open the key body e normally leads to accessibility to the components of the printed circuit board that is inside the key body.
• the present invention is intended in particular to overcome the drawbacks of the prior art, and in particular those mentioned above, and also aims to provide a mechanical module, particularly for a key to a vehicle that is inexpensive and which However avoids that during an exchange of the battery access to the components that are on the printed circuit board is allowed.
• a mechanical module in particular for a key, comprising a body, the body comprising a first body part, a second body part, a printed circuit board and a battery, the first and second parts of body being mechanically fixed relative to each other, the printed board being fixed to the first body part by means of a permanent fixing, the battery being positioned between the printed board and the second body part, the body being provided such that the battery can be exchanged without giving access to the body compartment between the printed board and the first part of the body.
• the housing of the mechanical module such that it is possible to exchange the battery but without access to the components on the printed circuit board.
• the various elements of the key it is advantageously possible for the various elements of the key to be maintained when the key body is opened, the opening being necessary because of an exchange of the battery.
• a preferred improvement of the invention lies in the fact that the permanent attachment is a snap fastener.
• Another preferred refinement of the invention lies in the fact that the permanent fixation is an ultrasonic welding attachment.
• Another preferred refinement of the invention lies in the fact that the permanent attachment is a bonding attachment.
• a preferred development of the invention lies in the fact that the mechanical module comprises at least one sealing element between the first body portion and the printed circuit board.
• the module is a key module comprising an insert mounted on the body.
• the insert is able to pivot about an axis of rotation between a position of use and a storage position, the mechanical module preferably being of the type comprising a pivoting support, carrying the insert and cooperating with a control button.
• a preferred refinement of the invention lies in the fact that the first and second body parts are mechanically fixed relative to each other through a form connection which allows a high stability of the key body.
• the present invention also relates to a key, in particular a vehicle key, the key comprising a mechanical module according to the present invention.
• Figure 1 is a schematic view of a vehicle key according to the present invention, the key comprising an example by an insert and the insert being in a storage position.
• Figure 2 is a schematic view of the vehicle key according to the present invention, the key comprising an example by an insert and the insert being in a position of use.
• Figure 3 schematically shows a sectional view of the mechanical key module comprising a first portion and a second body portion according to the present invention.
• Figures 1 and 2 of the accompanying drawing show by way of example a key 1 comprising a mechanical module according to the present invention.
• the key 1 is intended, for example, to lock or unlock the opening of the vehicle, to control a lock and a starter of this vehicle, etc.
• the key 1 comprises a key body 2, generally clevis-shaped, comprising at least a first portion 21 of a key body housing 2 and a second portion 22 of a body housing 2 of key.
• the first and second portions 21, 22 are preferably made by molding.
• the key may comprise an insert 8 and a control button 5 controlling the rotary movements of the insert 8 relative to the key body 2 around an imaginary axis of rotation (or pivoting) of the insert 8 relative to the key body 2.
• the insert 8, also called bit, is provided, for example, of generally planar shape. The rotational movement about the axis of rotation allows the displacement of the insert 8 between a storage position, as illustrated in particular in FIG. 1, and a position of use, as illustrated in particular in FIG. .
• Figure 3 shows a schematic sectional view of a housing or a mechanical moduie comprising a first portion 21 and a second portion 22 according to the present invention.
• the key body 2 comprises a printed circuit board 3 with electronic elements or components K.
• the electronic elements or components K comprise conventional electronic means intended for example to remotely control means for locking the doors of the vehicle or means of identification of the vehicle. a user who is authorized to use the vehicle.
• the printed circuit board 3 is fixed to one of the parts 21, 22 of the key body 2 via a permanent fastener 9. In the example shown in FIG. 3, the printed circuit board 3 is fixed to the first part 21. of body. It is also possible according to the present invention that the printed circuit board 3 is fixed to the second body part 22.
• the electronic elements or components K are preferably provided in the compartment 11 and the battery 6 is provided in the other compartment 12.
• compartment 11 forms a sealed space with respect to the outside of the key body 2 but also with respect to the other compartment 12. This sealing is achieved by means of sealing elements D1, D2, D3, for example elements provided in an elastic material.
• the permanent attachment 9 of the printed circuit board 3 to the first body portion 21 can be achieved through a peeling process.
• This is a low-temperature welding process (normally up to 300 ° C) that allows assembly of high mechanical quality, while ensuring high quality of appearance and high assembly repeatability.
• the permanent attachment 9 is made via ultrasonic welding or by gluing.
