(16) In reference to FIG. 3 and according to the first embodiment, the cavity 21 is located between the coupling and clamping housings.

(17) In reference to FIGS. 2, 3 and 4, the fork crown 2 also has a means for coupling 24 to the steering shaft. This coupling means 24 is formed by the joining of the body 20 and of the cover 22.

(18) According to FIGS. 2 and 3, the body 20, in complement to the coupling and clamping housings 23, has two clamping pads 230, each intended to be re-clamped onto the body by way of complementary screws of two tapped holes 231 located on these clamping pads. By screwing the complementary screws in the two tapped screws, the fork tubes previously inserted in the coupling and clamping housings 23 are surrounded.

(19) Such as illustrated by FIGS. 2, 3 and 6, the body 20 also has: a first communication space 25 with a space located in front and above the fork crown, the fork crown comprising, at the level of this second communication space, an excrescence with means for fixing 250 to a complementary member; a second communication passage 26 with a space located above the body 20 of the fork crown 2; a third communication passage 27 with a space located at the front and below the fork crown, the fork crown comprising, at the level of this third communication space, a camera 270 intended to film towards the front of the motorised vehicle.

(30) In case of an electricity provision failure from the electrical supply circuit of the motorised vehicle, the emergency battery 5 can bridge and continue to supply the electronic board located in the cavity of the body of the fork crown.

(31) Thanks to these components and according to this embodiment where the motorised vehicle is a motorcycle, the electronic board can achieve a geolocation of the motorcycle. This geolocation makes it possible to monitor the motorbike in real time. In case of suspecting a theft of the motorbike, an alert is sent to the driver, and a silent monitoring of the motorcycle can be achieved thanks to the sending of a signal over the narrowband cell network.

(32) The electronic board located in the fork crown can also achieve an automatic detection of the status of the motorised vehicle (stopped, started, or moving, etc.) and makes it possible to adapt, according to the pre-set parameters, the functionalities available to the driver of the motorised vehicle.

(33) Thanks to the wireless communication module able to create a computerised network, the driver can also connect this computerised equipment to a private Wi-Fi network generated by the electronic board located in the fork crown.

(35) In reference to FIG. 5, the cavity 21 can also comprise a memory 45. This memory makes it possible to store data collected and/or transmitted by the electronic components.

(36) Such as mentioned above, the motorised vehicle also comprises a camera 270. In reference to FIG. 5, this camera 270 is integrated in the fork crown 2.

(37) More specifically, a camera lens which passes through the third communication passage presented by the fork crown is observed, and the electronic board 4 comprises a camera controller 271 coupled with this camera lens.

(38) According to an application example, the camera and the memory make it possible to store photos or videos of a motorised vehicle path.

(39) Finally, such as mentioned above, the accelerometer also makes it possible for the fork crown and for the electronic board to have fall and/or theft detection functions. More specifically, dangerous events for the motorised vehicle can be detected, that is: a fall; a movement of the motorcycle; a lifting of the motorcycle; etc.

(40) In reference to FIGS. 7 to 10, a second embodiment of the fork crown is described below.

(41) The upper fork crown 2 has a body 20.

(42) This body 20 has a cavity 21. The cavity is closed by a cover 22.

(43) The body 20 also comprises: coupling and clamping housing 23 intended to receive fork tubes 100; a means for coupling 24 to the steering shaft.

(44) Different from the first embodiment, the body 20 has a cavity 21 which is not located between the coupling and clamping housings 23.

(45) Indeed, the cavity 21 is positioned offset with respect to a central portion 200 of the fork crown 2.

(46) More specifically, according to this embodiment, the body 20 of the fork crown 2 comprises: a central portion 200, having coupling and clamping housings 23 as well as the means for coupling 24 to the steering shaft; a remote portion 201, having the cavity 21; an arm 202 coupling the remote portion 201 to the central portion 200.

(47) Preferably, the central portion 200, the remote portion 201 and the arm 202 form a single-piece assembly.

(48) This body 20 is advantageously made of aluminium.

(49) The remote portion 201 is intended to be located at the front of the fork crown 2.

(50) According to the present embodiment illustrated by FIGS. 7 to 10, the cover 22 takes a tank form. In this manner, the cavity arranged in the body 20 of the fork crown, the more specifically in the remote portion 201 of the body 20, has a significant volume when the cover 22 closes the cavity 21.

(51) In reference to FIG. 10, the remote portion 201 of the body 20 of the fork crown 2 has a complementary lower peripheral edge 2010 of the cover 22.

(52) During the implementation of the cover, the latter must be returned on this lower peripheral edge 2010, then, such as illustrated by FIG. 9, complementary screws 220 with tapped holes 2200 located on the cover 22 are used to fix the cover to the body 20 of the fork crown. These screws are in particular screwed from an upper face of the remote portion 201 of the fork crown 2.

(53) According to the principle of an exemplary embodiment of the invention, an electronic board (not represented) is housed in the cavity. This electronic board is able to centralise and/or process data supplied by said electronic component(s), and comprises control means coupled with at least one member of the motorised vehicle, the control means being able to start, and/or stop and/or modify the performance of the member from the electronic board.

(54) Such as illustrated by FIGS. 9 and 10, the remote portion 201 of the body 20 has a second communication passage 26 between the cavity 21 and a space located above the body 20 of the fork crown 2.

(55) In reference to FIGS. 7 and 10, the fork crown 2 has a communication opening 222 in particular able to let connection cables intended to connect the electronic board to the electronic components located on the motorised vehicle pass through. Different from the first embodiment, this communication opening 222 is presented by the remote portion 201 of the body 20 and not by the cover 22.

(56) According to FIGS. 8 to 10, the fork crown 2 comprises means for integrating an external computerised unit 7, in particular mobile and communicating, such as a smartphone (telephone). This external computerised unit is intended to engage with the electronic board housed in the cavity, and be used to display information relating to the motorised vehicle by means of the screen of the external computerised unit.

(57) This external computerised unit 7 can, for example, be used to be used as a digital speedometer.

(58) These means for integrating the external computerised unit 7 comprise: an upper face of the remote portion 201 of the body 20 of the fork crown; a support for receiving 70 the external computerised unit 7; a cover 71.

(59) The upper face of the remote portion 201 of the body 20 has a complementary upper peripheral edge 2011 of the cover 71.

(60) Such as illustrated by FIG. 10, complementary assembly screws 710 with holes 711 located on the cover 71 make it possible to assemble the cover on the remote portion 201 of the body 20 of the fork crown 2.

(61) The receiving support 70 is received in a reinforcement presented by the upper face of the remote portion 201, this reinforcement being more specifically delimited by the upper peripheral edge 2011.

(62) The receiving support 70 is specific to the external computerised unit 7 and has, for this purpose, a complementary imprint of the form of the external computerised unit 7. According to another, non-illustrated embodiment, the receiving support could be able to receive external computerised units of different forms by having a sufficiently large deformation capacity.

(63) Such as illustrated in FIG. 8, the receiving support 70 has indentations 700 making it possible to facilitate the removal of the external computerised unit 7 from the receiving support 70.

(64) According to the present embodiment, the receiving support 70 has an elastic deformation capacity. The receiving support 70 is, in particular, made of silicone.

(65) This elastic deformation capacity makes it possible to interlock the external computerised unit 7 inside the imprint.

(66) The elastic deformation capacity of the receiving support 70, as well as the imprint presented by said receiving support form means for holding the external computerised unit 7 in the receiving support 70.

(67) According to a preferable, non-illustrated feature, the fork crown comprises an electrically inductive charger. To this end, the receiving support comprises a housing able to receive an inductive recharging antenna. This recharging antenna is coupled with the electronic board located inside the cavity by way of the second communication passage 26 (illustrated in FIGS. 9 and 10).

(68) The housing is located below the imprint and intended to make it possible for an inductive recharging of the external computerised unit 7.

(69) The cover 71 is hollowed out. It thus makes it possible to insert the external computerised unit into the imprint of the receiving support 70, to access the external computerised unit 7 to interact with, or finally to remove it from the imprint.

(70) During the assembly of the cover 71 on the remote portion 201, the cover confines the receiving support 70 to hold it in position. By confining the receiving support 70, the cover 71 also makes it possible to limit the possible deformations of the receiving support 70 and thus to improve the capacity of the receiving support to hold the external computerised unit 7 inside the imprint.

(71) The cover can be made of aluminium or made of plastic.

(72) According to the present embodiment illustrated by FIG. 8, the remote portion 201 of the body 20 is mainly located in the same plane as the portion 200 of the body 20. The orientation of the screen intended to be presented by the external computerised unit is thus dependent from the orientation of the fork tubes on which the fork crown is assembled.

(73) According to another embodiment, not illustrated, the fork crown can comprise means for modifying the inclination of the screen. To this end, the arm coupling the remote portion to the central portion can have an articulation, or an adapter able to modify the inclination of the screen can be positioned on the upper face of the remote portion, below the receiving support and the cover.

(74) Although this is not described, the first embodiment and the second embodiment can be at least partially combined together.

(75) For example, the cover 22 of the remote portion 201 of the fork crown 2 of the second embodiment (illustrated in FIG. 8) can have a third communication passage 27 with a space located at the front and below the fork crown 2 like for the body 20 of the fork crown 2 of the first embodiment (illustrated in FIG. 6). The fork crown could thus comprise, at the level of this third communication space, a camera intended to film towards the front of the motorised vehicle.

(76) An exemplary embodiment of the invention in particular aims to meet the expectation referred to in the Background section.

(77) More specifically, an exemplary embodiment of the invention proposes a solution making it possible to have a motorised vehicle with a fork crown, which integrate new electronic technologies, in particular in view of communicating or receiving navigation information.

(78) An exemplary embodiment proposes such a solution that does not impact or has little impact on the appearance of the motorised vehicle.

(79) Although the present disclosure has been described with reference to one or more examples, workers skilled in the art will recognize that changes may be made in form and detail without departing from the scope of the disclosure and/or the appended claims.
