Description
Title of the invention: LAND VEHICLE WITH OPTICAL BLOCK(S) IN PRE-MAINTAINED POSITION ON AN ARMATURE Technical field of the invention
[0001] The invention relates to land vehicles comprising a frame on which at least one optical unit must be fixed. State of the art
[0002] Some land vehicles, often of the automobile type, include, generally in a front section, a frame to which at least one optical unit is attached. For example, the frame may be part of a bumper, and two optical units, right and left, may need to be attached to right and left sections of it.
[0003] In some of these vehicles, the frame includes an upper face which is provided in at least a first location with a first fixing interface (optionally a hole for screwing in a fixing screw), and each optical block includes a fixing tab having in a second location a second fixing interface (optionally a through hole) which cooperates with the first fixing interface to participate in the final fixing of the optical block on the frame.
[0004] Currently, once a technician has partially fixed an optical block to the frame using a partially tightened fixing screw passing through the first and second fixing interfaces, they must connect the optical block connectors to the corresponding electrical harnesses. However, when the connector environment is (very) cluttered and / or (very) cramped, the connection operations prove very difficult and ergonomically unappealing for the technician. Furthermore, the technician's hand and / or forearm movements against the optical block can damage the first fixing interface, which can degrade the quality of the fixing and subsequently cause annoying noises in the presence of vibrations and / or shocks.
[0005] It should be noted that when the upper face of the armature also includes at least one first indexing interface (such as a pin) and the fixing tab of an optical block also includes a second indexing interface (such as a through hole) cooperating with the first indexing interface during final fixing, the aforementioned movements can also cause damage to the first indexing interface, which can sometimes prevent correct positioning of the optical block relative to the armature.
[0006] The invention therefore aims in particular to improve the situation. Presentation of the invention
[0007] It proposes in particular for this purpose a land vehicle comprising an armature, having an upper face provided in at least a first place with a first fixing interface, and at least one optical block, having a fixing tab comprising in a second place a second fixing interface cooperating with the first fixing interface to participate in a final fixing of the optical block on the armature.
[0008] This vehicle is characterized by the fact that:
[0009] - the upper face of the frame comprises at least one third place, offset relative to the first corresponding location along a longitudinal direction of the vehicle and / or a transverse direction of the vehicle, a first pre-holding interface, and
[0010] - the fixing tab includes in a fourth place, offset from the second location along the longitudinal and / or transverse direction, a second pre-holding interface cooperating with the first pre-holding interface to ensure pre-holding of the optical block relative to the frame before final fixing.
[0011] Thus, the optical block is temporarily held in the pre-holding position away from its final fixing position, which leaves more space for the technician who installs it in the vehicle to connect its connectors to the corresponding electrical harnesses.
[0012] The vehicle according to the invention may include other features which may be taken separately or in combination, and in particular:
[0013] - the third location can be offset relative to the first location following the longitudinal direction and the transverse direction, and the fourth place can be offset from the second place along at least the transverse direction;
[0014] - the first pre-holding interface can be a first pawn, and the second The pre-holding interface can be a through hole suitable for housing part of this first pawl;
[0015] - the first fixing interface can be a hole adapted for the passage of a screw fixing, and the second fixing interface can be a through hole suitable for the passage of the fixing screw;
[0016] - the upper face of the frame may include in a fifth place, offset relative to the first location following at least the longitudinal direction, a first indexing interface, and the fixing lug may include in a sixth a second indexing interface cooperating with the first indexing interface during final fixation;
[0017] - in the presence of the last option, the first indexing interface can be a second pawl, and the second indexing interface can be a through hole adapted to house part of this second pawl;
[0018] - in the presence of the last sub-option, the sixth location can be shifted by report to the second location following at least the longitudinal direction;
[0019] - the upper face of the frame may include two first places in right and left sections. In this case, the vehicle may include two right and left headlight assemblies;
[0020] - the frame may be part of a bumper, possibly a front bumper;
[0021] - each optical block can perform at least one photometric function lighting selected from a photometric high beam function and a photometric low beam function;
[0022] - it can be of the automotive type. Brief description of the figures

[0027] [Fig.4] schematically illustrates, in a top view, the fixing position of the optical block of [Fig.2] on the right end of the armature of [Fig.1]. Detailed description of the invention
[0028] The invention aims in particular to provide a land vehicle comprising an AP frame on which at least one BO optical block must be fixed after a pre-fixing phase enabling a technician to proceed with the connection of the electrical harnesses on the connectors of this BO optical block.
[0029] In what follows, the land vehicle is considered, by way of non-limiting example, to be a motor vehicle, such as a car. However, the invention is not limited to this type of land vehicle. It relates to any land vehicle comprising a frame on which at least one optical unit must be fixed.
[0030] Furthermore, in what follows, it is assumed, by way of non-limiting example, that the AP frame and each associated BO optical unit are intended to form part of the front section of a land vehicle. However, this is not mandatory. Indeed, they could be intended to form part of the rear section of a land vehicle.
[0031] Furthermore, in what follows, by way of non-limiting example, each optical unit BO is considered to be a projector (or headlight) providing at least one lighting function, such as a high beam or low beam function. However, the invention is not limited to this type of optical unit.
[0032] Finally, in what follows, by way of non-limiting example, we consider that the AP frame is intended to be part of a bumper (here, a front bumper). But this is not mandatory.
[0033] Taking into account all the assumptions described above, the AP frame comprises two right and left parts on which two optical blocks BO right and left are intended to be fixed respectively.
[0034] In the preceding and following text, the term "front" is defined with respect to the front end of the vehicle, and the term "rear" is defined with respect to the rear end of the vehicle (opposite the front end). Therefore, the front part of an element is oriented towards the front end of the vehicle, while the rear part of that element is oriented towards the rear end of the vehicle.
[0035] In figures 1 to 4, the X direction is the longitudinal direction of the vehicle, which is parallel to the side sides including the side doors, the Y direction is the transverse direction of the vehicle, which is perpendicular to the side sides and to the longitudinal direction X, and the Z direction is the vertical direction of the vehicle, which is perpendicular to the longitudinal direction X and the transverse direction Y.
[0036] Figures 1, 3, and 4 schematically illustrate a portion of the right end of an example embodiment of an AP frame for a land vehicle according to the invention. As illustrated, this AP frame comprises an upper face FS which is provided at least once with a first attachment interface IF1 and at least once with a third attachment interface IPI. Each third location is offset from the corresponding first location along the longitudinal direction X and / or the transverse direction Y.
[0037] It will be noted that, given the assumptions described above, the upper face FS of the AP frame is provided in the right part (or end) with a first first place comprising a first first fixing interface IF1 and a first third place comprising a first first pre-maintaining interface IPI, and in the left part (or end) with a second first place comprising a second first fixing interface IF1 and a second third place comprising a second first pre-maintaining interface IPI.
[0038] Figures 2 to 4 schematically illustrate at least partially an example of the realization of an optical block BO intended to be fixed on the (here) right end of the AP armature of [Fig.1].
[0039] As can be seen more clearly in [Fig. 3], each optical block BO comprises a lens G fixedly attached to a housing BB having a mounting tab PF. As illustrated in Figures 2 to 4, this mounting tab PF includes, at a second location, a second mounting interface IF2 and, at a fourth location, a second pre-retaining interface IP2. This fourth location is offset relative to the second location along the longitudinal direction X and / or the transverse direction Y.
[0040] It should be noted that the PF mounting tab is preferably an integral part of the BB housing, as illustrated, but not limited to, examples. In this case, it can be formed during the molding of the BB housing in a mold. However, in an alternative embodiment not shown, the PF mounting tab could be attached to the BB housing, for example by gluing or screwing.
[0041] The second pre-holding interface IP2 is arranged to cooperate with the first pre-holding interface IPI of the AP frame to ensure pre-holding of the optical block BO relative to this AP frame before the final fixing of the optical block BO onto the AP frame. The pre-holding position of the optical block BO on the right end of the AP frame is schematically illustrated in [Fig. 3].
[0042] The second fixing interface IF2 is arranged to cooperate with the first fixing interface IF1 of the AP frame to participate in the final fixing of the optical block BO onto this AP frame. The fixing position of the optical block BO on the right end of the AP frame is schematically illustrated in [Fig.4].
[0043] Thanks to this pre-holding position, made possible by the cooperation of the first IPI and second IP2 pre-holding interfaces, the BO optical unit is temporarily held away from its final mounting position. This gives the technician installing it in the vehicle more space to connect its connectors to the corresponding electrical harnesses. The result is easier connection with improved ergonomics, and also prevents damage to the first mounting interface IF1 because it is no longer under stress during the connection, thus avoiding any degradation in the quality of the mounting.
[0044] For example, and as illustrated without limitation in Figures 1, 3 and 4, the third location can be offset from the first location along the longitudinal direction X (here forward) and the transverse direction Y (here to the left for the right optical block BO). In this case, and as illustrated without limitation in Figures 2 to 4, the fourth location can be offset from the second location at least along the transverse direction Y (here to the left for the optical block BO). BO right). This arrangement is particularly advantageous because in the pre-maintenance position ([Fig.3]) it allows the optical block BO to be moved longitudinally and transversely away from the AP frame relative to the fixing position ([Fig.4]).
[0045] But in an alternative embodiment not shown, the third location could be offset from the first location along the only longitudinal direction X. This alternative arrangement allows the optical block BO to be moved longitudinally away from the armature AP in the pre-holding position relative to the fixing position.
[0046] In an alternative embodiment not shown, the third location could be offset from the first location along the only transverse direction Y. This alternative arrangement allows, in the pre-holding position, the optical block BO to be moved transversely away from the armature AP relative to the fixing position.
[0047] Also, for example, and as illustrated without limitation in Figures 1, 3 and 4, the first pre-holding interface IPI can be a first pin. In this case, and as illustrated without limitation in Figures 2 to 4, the second pre-holding interface IP2 is a through hole that is adapted to house a portion of the first pin IPI.
[0048] By way of example, and as illustrated, the first IPI pawn may have a section in the general shape of a cross.
[0049] Also, for example, and as illustrated without limitation in Figures 1, 3 and 4, the first fastening interface IF1 can be a hole adapted for the passage of a fastening screw VF. In this case, and as illustrated without limitation in Figures 2 to 4, the second fastening interface IF2 is a through hole adapted for the passage of this fastening screw VF.
[0050] It should be noted that the hole IF1 can be threaded in order to avoid having to add a nut (possibly by welding or gluing) on the lower face of the AP reinforcement (opposite to its upper face FS).
[0051] Also, for example, and as illustrated without limitation in Figures 1, 3, and 4, the upper face FS of the AP frame may include, at a fifth location offset from the first location along at least the longitudinal direction X (here towards the rear), a first indexing interface III. In this case, and as illustrated without limitation in Figures 2 to 4, the fixing tab PF includes, at a sixth location offset from the second and fourth locations, a second indexing interface 112 arranged to cooperate with the first indexing interface III during final fixing. It will be understood that the indexing here is positional. It ensures that, when the first IF1 and second IF2 fixing interfaces cooperate together (as well as here with the fixing screw VF) and the first III and second 112 indexing interfaces cooperate together, the optical block BO is correctly positioned relative to the armature AP.
[0052] It should be noted that in the presence of this option, the pre-holding position of the optical block BO makes it impossible to damage the first indexing interface III because it is no longer stressed during the connection, which prevents incorrect final positioning.
[0053] For example, and as illustrated without limitation in Figures 1, 3 and 4, the first indexing interface III may be a second pin. In this case, and as illustrated without limitation in Figures 2 to 4, the second indexing interface 112 is a through hole that is adapted to house a portion of the second pin III.
[0054] By way of example, and as illustrated, the second pawn III may have a section in the general shape of a cross.
[0055] For example, and as illustrated non-limitingly in Figures 2 to 4, the sixth location can be offset from the second location along at least the longitudinal direction X. It should be noted that in the illustrated example, the sixth location is offset from the second location along the longitudinal direction X (here towards the rear) and very slightly along the transverse direction Y (here towards the right for the right optical block BO).
