Technical Field

[0001] The present invention relates to an electronic key housing for a motor vehicle, and a key for a motor vehicle latch including such a housing. Background Technology

[0002] An electronic key housing is known in the prior art, which includes a control panel with one or more control buttons for remotely actuating a vehicle.

[0003] The control buttons on these housings are structurally different from each other and are assembled independently on the housings to ensure that the control buttons are not interfered with during the actuation of other control buttons.

[0004] If these control housings are intended to prevent the risk of accidental triggering of control buttons, their manufacture would require individual configuration for each control button. Summary of the Invention

[0005] The present invention aims, in particular, to provide an electronic key housing for a vehicle that includes an improved control board that reduces the number of components used for its setup while limiting the risk of interference during the actuation of the control buttons.

[0006] Therefore, the present invention relates to an electronic key housing for a vehicle, the electronic key housing comprising a body for housing an electronic control device, the housing comprising a control board comprising a first group and a second group of control buttons.

[0007] The control buttons of the first group are interconnected by fastening parts, and the first and second groups are stacked and assembled on the main body by snap-fit ​​components.

[0008] The first group rests against the main body at the level of the fastening part to form the first zone where the buttons of the first group pivot relative to the main body.

[0009] It should be understood that the first pivot area forms a support area for the shell to support the first and second groups.

[0010] The assembly of the first and second groups allows the control buttons of the first group to pivot relative to each other and relative to the housing simultaneously.

[0011] This greatly limits the risk of interference from another control button when one control button is being used.

[0012] According to an embodiment of the housing of the present invention, the fastening portion of the first group includes a protrusion, the first group resting against the body via the protrusion, or alternatively, the body includes a protrusion, the body resting against the fastening portion of the first group via the protrusion.

[0013] This protrusion facilitates the pivoting of each group relative to the main body.

[0014] According to another embodiment of the housing of the invention, the second group is a bit group of control buttons, the second group abutting the fastening portion to form a second pivot area of ​​the buttons of the second group relative to the first group.

[0015] Each group of bits in the control buttons forms a single unit. In other words, the control buttons that make up the board are inseparable from each other. This facilitates the assembly of the control board onto the housing.

[0016] In another embodiment of the housing according to the invention, the first pivot region and the second pivot region pass through the same axis perpendicular to the first pivot region.

[0017] In another embodiment of the housing according to the invention, a snap-fit ​​element is movably mounted in the through-window of the housing to ensure the mobility of the control button.

[0018] According to another embodiment of the housing of the invention, the first and second position groups of the control buttons are mounted without gaps in a direction perpendicular to the first pivot area.

[0019] This gapless installation further reduces the risk of interference between control buttons.

[0020] According to another embodiment of the housing of the present invention, the outer surfaces of the first group and the second group are flush with each other.

[0021] According to another embodiment of the housing of the invention, the fastening portion 12A1 has a curved shape that allows the second set 12B to pivot.

[0022] According to another aspect, the present invention relates to a key for a motor vehicle latch, the key comprising an electronic key housing according to any of the foregoing features.

[0023] Advantageously, the vehicle latch key does not have a metal insert designed to be inserted into the vehicle latch.

[0024] Advantageously, the vehicle latch key has a metal insert designed to be inserted into the vehicle latch. Attached Figure Description

[0032] Reference Figure 1 The figure shows an electronic key housing 1 for a motor vehicle according to the present invention.

[0033] The housing 1 is formed by assembling a body 2, 3 comprising first and second half-shells 2, 3. Each half-shell 2, 3 includes complementary connecting edges 20, 30 for assembling them to each other. These connecting edges 20, 30 of the two half-shells 2, 3 are assembled together to hold the two half-shells 2, 3 in the connecting plane P.

[0034] Reference Figure 2 and 3 A compartment 8 is provided within the first half-shell 2 to accommodate an electronic control device 9. This electronic control device 9 is formed of an electronic card of the printed circuit board (PCB) type. The electronic control device 9 is powered by a battery 11 located inside the shell 1. The internal battery 11 can be, for example, a battery.

[0035] The compartment 8 is closed by a retaining plate 10, which has an opening 10' for accessing the internal battery 11.

[0036] exist Figure 4 The image shows the first half-shell 2, and... Figure 6 Unlike other shells, the first half-shell 2 is not equipped with... Figure 5 The control panel 12 shown.

[0037] The control board 12 is provided for controlling the electronic control device 9.

[0038] As shown in the figure, the control board 12 includes a first bit set 12A and a second bit set 12A and 12B of control buttons that are different from each other.

[0039] Each control button controls remote functions of the vehicle, such as locking or unlocking the doors, and even pre-ignition the vehicle.

[0040] The first and second groups 12A and 12B of the control buttons are complementary shapes.

[0041] In addition, each bit group of the control buttons includes two control buttons and has a shape that is symmetrical along an axis passing through its center.

[0042] Each bit group of the control buttons includes a snap-fit ​​element 13, which is configured to engage in the through window 26 of the first half-shell 2.

[0043] These snap-fit ​​elements 13 are movably mounted in these through windows 26 to ensure the mobility of the control buttons when pressed.

[0044] like Figure 2 and 3 As shown, the first group 12A and the second group 12B are stacked on top of each other during assembly into the shell portion 20 of the main body 2, 3 of the housing 1. In this case, the shell portion 20 is the first half-shell 2. The assembly of the first and second groups 12A, 12B onto the main body 2, 3 of the housing 1 is achieved by snap-fit ​​element 13.

[0045] In this assembly position, the outer surfaces 12A' and 12B' of the first and second groups 12A and 12B are flush with each other.

[0046] In addition, each bit group 12A, 12B of the control buttons includes a terminal 14 for each control button, which is configured to engage in a through opening 27 in the first half-shell 2 to allow the corresponding switch of the electronic control device 9 to be carried.

[0047] The control buttons of the first group are attached to each other via fastening part 12A1.

[0048] In the assembled state, the first group 12A is sandwiched between the second group 12B and the main bodies 2 and 3 of the housing 1. Then, the fastening part 12A1 is held against the main bodies 2 and 3 of the housing 1 by the second group 12B.

[0049] Then, the first group 12A abuts against the main body 2, 3 of the housing 1 through the protrusion 12A11 of the fastening part 12A1, forming the first pivot area Z1 of the button of the first group relative to the main body 2, 3 of the housing 1, and the second group 12B itself abuts against the fastening part 12A1 to form the second pivot area Z2 of the button of the second group 12B relative to the first group 12A.

[0050] The fastening portion 12A1 advantageously has a curved shape that allows the second set 12B to pivot.

[0051] It should be understood that the control buttons of the first and second groups 12A and 12B are then pivotally installed according to the same pivot point formed by the first pivot zone Z1.

[0052] The first and second groups 12A and 12B of the control buttons are mounted without clearance in a direction perpendicular to the first pivot zone Z1. This clearance-free mounting prevents untimely actuation of one of the control buttons in the group when the other is actuated.

[0053] In the assembled state, the first pivot region Z1 and the second pivot region Z2 pass through the same axis perpendicular to the first pivot region Z1.

[0054] This configuration also allows for a reduction in the risk of one control button interfering with another when actuating a control button.

[0055] Obviously, the present invention is not limited to the examples just described, and many modifications can be made to these examples without departing from the scope of the invention. In particular, different features, shapes, variations, and embodiments of the present invention can be associated with each other in various combinations, as long as they are not incompatible or mutually exclusive. In particular, all the above variations and embodiments can be combined with each other.
