Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This patent application claims the priority of Italian Patent Application No. 102019000001797 filed on February 7, 2019, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] The invention relates to a motion transmission device having a force limiter function between a first component and a second component, which is particularly suitable for a lighting device of a vehicle, wherein the first component is an electric motor and the second component is a reflector or a lighting element of the lighting device, which must be moved in order to guide a light beam generated by the lighting device while turning a corner and / or to adjust the direction of the light beam depending on the load (passengers / luggage) measured on the vehicle. Background Art

[0004] As is known, vehicle lighting devices include a cup-shaped body or housing usually molded from a synthetic plastic material, at least one lighting element housed in the cup-shaped body and equipped with or without a reflector, and a transparent element arranged to close the front opening of the cup-shaped body and face the driving direction of the vehicle in use.

[0005] In order to prevent unintended glare for other vehicles, in particular in the presence of luggage and / or passengers in the rear compartment, it is necessary to be able to adjust the vertical output direction of the light beam generated by the lighting device relative to the respective weight of the vehicle. For this purpose, an electromechanical device is used which appropriately moves the reflector or lighting element (on command by a user or a sensor) and comprises an electric motor or a linear actuator acting on the reflector or lighting element via a mechanical transmission device.

[0006] However, especially after repeated and frequent use, the mechanical transmission device may unexpectedly become stuck, thereby overloading the electric motor or the actuator, resulting in their premature wear or failure.

[0007] This problem exists in particular in the case of adaptive lighting systems, in which, for example, reflectors or lighting elements are routinely rotated in order to direct the light beam, for example, depending on the curve that the vehicle is executing.

[0008] Finally, it should be noted that there are also projectors without external lenses, in which the adjustment mechanism can be stressed not only by accidental jamming but also by external events (such as vandalism) or in any other situation where excessive forces are exerted on the lighting element. Summary of the invention

[0009] The object of the invention is to provide a device for transmitting movement between a first component and a second component which is particularly suitable for a lighting device of a vehicle, does not have the disadvantages of the prior art, in particular has a force limiter function, and is also simple and economical to manufacture, highly reliable and small in size.

[0010] According to the invention, a motion transmission device as defined below is therefore provided, which is particularly suitable for a lighting device for a vehicle and has a force limiter function between a first component and a second component.

[0011] The motion transmission device according to the present invention comprises: a bracket for fixedly receiving a first component; an output shaft of the first component that is axially movable relative to the bracket; a first shaft that is constructed to be constrained to a second component during use; and a mechanical connection device located between the axially movable output shaft and the first shaft.

[0012] According to the present invention, the mechanical connection device further includes: a cup-shaped body, which is fixed on the first shaft and slidably coupled to the bracket parallel to the output shaft and coaxially with the output shaft through at least one pair of side guides fixed on the bracket; a bushing installed inside the cup-shaped body, which is coaxial with the cup-shaped body and can slide relative to the cup-shaped body, and the bushing is axially constrained on the output shaft in a fixed manner so as to move integrally with the output shaft; at least one pair of radial holes formed in the radial inner side surface of the cup-shaped body, which side surface cooperates with the bushing; at least one pair of opposing pins, which are accommodated so that they can slide in corresponding radial receptacles of the bushing set in the bushing until they pass through the radial outer side wall of the bushing. The radial seat also accommodates a first spring that cooperates with the pin, and the first spring and the radial seat are constructed to enable the pin to be selectively in an extended position and a retracted position. In the extended position, the first end of the pin radially extends from the bushing in a cantilever manner so as to engage with the radial hole of the cup-shaped body and fix the cup-shaped body on the bushing, and in the retracted position, the first end of the pin resists the action of the first spring and is at least partially accommodated in the radial seat in a hidden manner so as not to engage with the radial hole of the cup-shaped body; and a second spring encapsulated between the bracket and the cup-shaped body and between the bracket and the corresponding shoulder element, the shoulder element is fixed relative to the cup-shaped body and is arranged on a side opposite to the cup-shaped body relative to the bracket.

[0013] Furthermore, the first end of the pin is defined by a corresponding surface which is arranged obliquely relative to the axis of symmetry of the output shaft and the bushing and is configured to cooperate with the periphery of the radial hole so as to urge the pin to the retracted position against the action of the first spring by any axial load exceeding a threshold applied to the first shaft during use.

[0014] Thus, when an axial stress greater than a threshold selected in the design phase is applied to the first axis, the pin is brought into the retracted position by the radial component of the axial stress due to the arrangement of the inclined surfaces at the ends of the pin.

[0015] In this retracted position of the pin, the bushing is no longer axially constrained on the cup-shaped body and is therefore free to move axially relative to the cup-shaped body, and the bracket connected to the bushing via the output shaft also moves against the action of the second spring.

[0016] As a result, even if the output shaft continues to move under the action of the first component, typically an electric motor or an actuator, it does not receive axial stress above a set threshold, thereby protecting the first component.

[0017] The set threshold value is determined at the design stage by appropriately determining the dimensions of the first and second springs and the inclination angle of the inclined surface relative to the axis of motion of the output shaft.

[0018] According to a preferred embodiment of the present invention, the mechanical connection device also includes a second shaft, which is constructed to be fixedly coupled to the output shaft of the first component on one side and to the bushing on the opposite side; in addition, the second shaft is connected to the bushing by a ball joint and preferably by a snap action.

[0019] The bushing preferably includes: an annular or cup-shaped barrel, preferably cylindrical, having a first end facing the first shaft and provided with a radial receptacle for the pin and the first spring; a cover for closing the second end of the barrel, the second end being opposite to the first end and open toward the bracket, the cover being provided with a hole to receive the output shaft into the barrel through the hole; and a ball joint, which fixedly receives the output shaft and is mated in contact with the first inner side surface of the barrel, the ball joint being blocked in the barrel in the axial direction by the cover.

[0020] Finally, in order to facilitate the assembly of the transfer device, the cup-shaped body is divided into two elements, including an annular element and a cup-shaped element coupled to its front part, which are integrally connected to each other by a detachable connecting member, preferably a screw; the cup-shaped element is provided with a radial hole, and both the annular element and the cup-shaped element are coaxial and constructed to receive the sleeve slidably inside them.

[0028] Reference Figure 1 , reference numeral 1 denotes as a whole a headlamp for a motor vehicle, which is configured to be fixed to a chassis (also known and not shown) of the vehicle by known means (not shown for the sake of simplicity).

[0029] The lighting device 1 comprises a substantially cup-shaped housing 2, a light source 3, a reflector 4 and a lens 5 closing the housing 2 at the front, the lens 5 being transparent (ie not modifying the light beam L generated by the light source 3) or optically active.

[0030] In order to guide the light beam L so as to simply compensate for changes in the vehicle's payload (passengers and / or luggage) (balance adjustment) or / and, for example, to make the light beam L follow a turn made by the vehicle (adaptive lighting function), the reflector 4 or (in the absence of a reflector 4) directly the light source 3 can be rotated vertically and / or horizontally by an adjustment device 6, the general structure of the adjustment device 6 is known, including an electric motor or actuator 7, a linear motion transmission device 8 from the motor / actuator 7 to the reflector 4 (or directly to the light source 3) and a manual balance adjuster 9, which is known and for simplicity is only schematically shown by a dotted box.

[0031] Generally speaking, the motion transfer device 8 is used to transfer linear motion between a first component (including the motor / actuator 7 in the example shown) and a second component whose orientation / balance must be changed, in the example shown, the second component including the reflector 4, but generally only including the light source 3.

[0032] According to the invention, the transmission device 8 is designed to have a force limiter function in order to protect the first component or the motor / actuator 7 from any overloads which could damage it.

[0033] For this purpose, the transfer device 8 ( Figure 2 ) comprises: a bracket 10 for fixedly receiving a first component 7; an output shaft 11 of the first component, which can move axially relative to the bracket 10; a first shaft 12, which is constructed to be constrained on the second component 4 (or 3) during use; and a mechanical connection device 13 located between the axially movable output shaft 11 and the first shaft 12.

[0034] According to the invention, the mechanical connection device 13 comprises a cup-shaped body 14, which in the example shown is delimited by a cylindrical side wall 15 and is coupled to the bracket 10 parallel to and coaxially with the output shaft 11 and slidably relative thereto by at least one pair of side guides 16, which are attached to the bracket 10 and protrude axially from the bracket 10 in a cantilevered manner toward the cup-shaped body 14. According to one aspect of the invention, the cup-shaped body 14 is fixed to the first shaft 12.

[0035] The mechanical connection device 13 further comprises a bushing 18 which is installed in the cup-shaped body 14, arranged coaxially with the cup-shaped body 14 and slidably received therewith, and the bushing 18 is axially integrated with the output shaft 11 in any known manner so as to move integrally therewith.

[0036] The side wall 15 of the cup-shaped body 14 has a radially inner side surface 19 ( Figure 4 ) is provided with at least one pair of opposite radial holes 20 (through holes in the example shown, but blind holes may also be used), and the shape of the radial holes 20 is preferably conical.

[0037] The side surface 19 also cooperates with the bushing 18 , in the example shown coming into contact therewith, and is preferably cylindrically symmetrical.

[0038] The mechanical connection means 13 also includes at least one pair of opposed pins 21 which are received in corresponding radial receptacles 22 ( Figure 4 and Figure 5 ) until it passes through the radially outer side wall 23 of the bushing 18.

[0039] The radial receptacle 22 also accommodates a first spring 24 cooperating with the pin 21 .

[0040] The spring 24 and the radial receptacle 22 are configured to allow the pin 21 to be selectively in the extended position ( Figure 3 ) and retracted position ( Figure 6 and Figure 7 ).

[0041] In the extended position of the pin 21 , the first end 25 of the pin 21 radially projects from the bushing 18 in a cantilevered manner to engage with the radial hole 20 of the cup-shaped body 14 and thus secure the cup-shaped body 14 to the bushing 18 .

[0042] In the retracted position, the first end 25 of the pin is at least partially housed in a concealed manner in the radial seat 20 , counter to the action of the first spring 24 , so as not to engage with the radial hole 20 of the cup-shaped body 14 .

[0043] In order to facilitate the introduction of the pin 21 into the receptacle 22 and to prevent its accidental release, the pin 21 ( Figure 5 ) and the receptacle 20 have a bayonet-type coupling portion.

[0044] The mechanical connection means 13 finally comprise a connection enclosed between the support 10 and the cup-shaped body 14 and between the support 10 and the corresponding shoulder element 27 ( Figure 5 ), a second spring 26 between the shoulder element 27 is fixed to the cup-shaped body 14 and is arranged on the side opposite to the cup-shaped body 14 relative to the bracket 10.

[0045] According to another important aspect of the present invention, the first end 25 of the pin 21 is formed by a corresponding surface 28 ( Figure 4 ) and, in the non-limiting example shown, is defined by a conical surface coaxial with the pin 21.

[0046] The inclined (conical) surface 28 is configured to be aligned with the peripheral edge 29 ( Figure 4 , which is also conical in the non-limiting example shown) so that any axial stress F ( Figure 6 and Figure 7 ) pushes the pin 21 to the retracted position against the action of the first spring 24, so that in the retracted position of the pin 21, the bushing 18 is no longer axially constrained to the cup-shaped body 14 and is therefore free to move axially relative to the cup-shaped body 14. For the same reason, the bracket 10 is also free to move relative to the cup-shaped body 14 together with the bushing 18 (but not necessarily with the same magnitude) against the action of the spring 26.

[0047] The mechanical connection device 13 further includes a second shaft 29 which is configured to be integrally coupled with the output shaft 11 of the first component 7 on one side and to be integrally coupled with the bushing 18 on the other side.

[0048] According to one aspect of the invention, the shaft 29 is connected to the bushing 18 via a ball joint 30 , which is preferably designed to allow a snap-fit ​​connection with the shaft 29 .

[0049] According to a preferred embodiment of the invention, the bushing 18 comprises: an annular or cup-shaped barrel 31, preferably cylindrical, having a first end 32 facing the first shaft 12 and provided with a radial receptacle 22 for the pin 21 and the spring 24; a cap 33 for closing a second end 34 of the barrel 31, opposite the end 32 and open towards the support 10; and a spherical joint 35 ( Figure 5 ), which fixedly receives the output shaft 11 and is in contact with the first inner side surface 36 of the cylinder 31.

[0050] The cover 33 is provided with a hole 37 for receiving the output shaft 11 therethrough into the barrel 31 , and the ball joint 35 is blocked in the barrel 31 in the axial direction by the cover 33 .

[0051] According to a preferred embodiment illustrated by way of non-limiting example, the output shaft 11 is integrally coupled to a second shaft 29 which is arranged coaxially with the output shaft 11 and which is also housed in the barrel 31 .

[0052] The shaft 29 is in turn coupled to the spherical joint 35 via the ball joint 30 radially inside the spherical joint 35, the ball joint 30 comprising a spherical head 38 integral with the shaft 29 at its first end opposite to the output shaft 11, and a spherical receiving element 39 for the spherical head 38 integral with the spherical joint 35 and extending axially in a cantilever manner toward the first end 32 of the barrel 31, the spherical receiving element 39 being coupled to the barrel 31 by the outer side surface of its spherical shape being in contact with the second inner side surface 40 of the barrel 31.

[0053] The shaft 12 is preferably integral with the cup-shaped body 14 coaxially with the output shaft 11 and protrudes axially from a bottom wall 41 of the cup-shaped body 14 in a cantilevered manner outside the cup-shaped body 14 on the opposite side of the bushing 18 .

[0054] Furthermore, the shaft 12 is preferably provided at one free end with a ball joint coupling element 42 for the second component 4 or 3 in order to receive stresses from this component.

[0055] In order to allow easy, simple and effective assembly and reliable operation of the spring 26, the bracket 10 has at least one pair of opposite first lugs 43 arranged in a radially cantilevered manner and arranged radially on the outside, each of which is bounded by a first face 44 facing the cup-shaped body 14 and a second face 45 facing the side opposite to the cup-shaped body 14 (only in Figure 5 ).

[0056] The face parts 44, 45 are respectively provided with opposing and coaxial first and second pins 46, 47 in an axially cantilevered manner.

[0057] The pins 46 , 47 are arranged parallel to the symmetry axis A of the output shaft 11 and the bushing 18 and partially support the cantilevered spring 26 , which is a coil spring each mounted on the corresponding first pin 46 or second pin 47 and coupled in contact with the first and second surfaces 44 , 45 of the lug 43 .

[0058] The cup-shaped body 14 is provided with a second lug 48 facing the lug 43 at the first lug 43 of the bracket 10 .

[0059] Corresponding pairs of straight longitudinal beams 49 extend parallel to the pins 46, 47 and extend in cantilevered fashion from the lugs 48 toward the bracket 10 ( Figure 5 ).

[0060] Between each pair of longitudinal beams 49, the corresponding radial outer end 50 of the lug 43 having the corresponding first pin 46 and the second pin 47 is slidably inserted in the axial direction, and the first pin 46 and the second pin 47 together with a pair of second springs 26 each mounted on the first pin 46 or the second pin 47 are also arranged between the pair of longitudinal beams 49.

[0061] The shoulder elements 27 are preferably formed of plates that are each snap-coupled to a respective free end 51 ( Figure 5 ).

[0062] The plate 27 and the lug 48 are preferably provided opposite one another with a cantilevered sleeve 52 coaxial with the pins 46 , 47 , into which the respective end of the spring 26 opposite the first lug 43 is inserted.

[0063] The sleeve 52 is also configured to cooperate with the radially outer end 50 of the lug 43 to serve as an axial end stop element of the bracket 10 when the pin 21 is in the retracted position.

[0064] Preferably, for ease of assembly, the cup-shaped body 14 is composed of two elements, including an annular element 53 and a cup-shaped element 54 coupled to the front of the annular element, which are integrally connected together by a detachable connecting member (preferably a screw 55).

[0065] The cup-shaped element 54 is an element having the radial hole 20 , and both the ring element 53 and the cup-shaped element 54 are coaxial with each other and are configured to slidingly receive the bushing 18 therein.

[0066] It is clear from the above description that the transmission device 13 is specifically configured to be accommodated in the vehicle lighting device 1 to connect the electric motor or actuator 7 with the reflector 4 or the light source 3 to change the orientation thereof.

[0067] For this purpose, the bracket 10 is also provided with a pair of side pads 56 on the opposite side of the side guide portion 16, which are configured to support the entire transfer device 13 inside the lighting device 1, and are specifically configured to be connected only to the side guide portion 16. Figure 1 The element 57 of the manual balance adjuster 9 is coupled, which is schematically shown by a dashed line.

[0068] Finally, the invention therefore also relates to a vehicle comprising a lighting device 1 , ie a headlight or a taillight, provided with a transmission device 13 as described for connecting an electric motor or an actuator 7 with a reflector 4 or a light source 3 in order to change its orientation.

[0069] By means of the described transfer device 13 it becomes clear that the lighting device equipped with this transfer device is protected against damage not only in the event of a jamming of the lighting element but also in the event of a projector without an external lens due to vandalism or in the event of excessive forces being applied to the lighting element.

[0070] Thus, all objects of the invention are achieved.
