Description

Theft-protecting arrangement for a vehicle headlight, vehicle headlight, vehicle, and method for hindering detachment of a vehicle headlight Technical Field The present disclosure relates to the area of vehicle headlights, and in particular to theft-protecting arrangements for hindering detachment of vehicle headlights from the vehicle.

Background Vehicle headlights have become desirable items to steal from vehicles because of their high value on the aftermarket. Design facilitating service and replacement of the headlight also makes unauthorized detachment of the headlights easier. Regarding heavy vehicles, the headlights are often stolen while the driver is sleeping in the vehicle. The detachment may only include unscrewing a few screws whereby the theft operation can be performed fast and quiet.

Several solutions have been proposed to hinder theft of headlights. FR253566OA1 and FR2699335A1 describe examples of anti-theft devices. However, these devices are directed to older designs of headlights. A more recent solution is to install a lower front grill lock that makes detachment of the headlight more difficult. Such grill lock is however expensive and does not seem to hinder theft of the headlamps efficiently enough. There is therefore a need for an improved solution to prevent theft of headlights from vehicles.

Summary lt is an object of the disclosure to alleviate at least some of the drawbacks associated with the prior art. ln particular it is an object to provide an anti-theft arrangement that complicates unauthorized detachment of vehicle headlights from a vehicle.

These object and others are at least partly achieved by the arrangement, vehicle headlight and vehicle according to the independent claims, and by the embodiments according to the dependent claims. 2 According to a first aspect, the disclosure relates to a theft-protecting arrangement for hindering detachment of a vehicle headlight from a vehicle. The vehicle headlight is pivotally attached to a front part of a vehicle via a hinge mechanism. The hinge mechanism comprises a vehicle bracket, a headlight bracket, and a vehicle knuckle connected to the vehicle bracket, a headlight knuckle connected to the headlight bracket and a hinge pin inserted through the vehicle knuckle and the headlight knuckle. The vehicle bracket is fastened to a front part of the vehicle via a fastening element and the headlight bracket is fastened to the vehicle headlight. The theft-protecting arrangement comprises a protecting device including a rigid elongated body with a housing part at a first end and a socket at a second end. The housing part is constructed to cover a head of the hinge pin and the socket is constructed to enclose a head of the fastening element. The theft-protecting arrangement further comprises a securing element configured to be arranged inside the socket. The theft-protecting arrangement is configured such that when assembled on the hinge mechanism, the housing part covers the head of the hinge pin to hinder removal of the hinge pin, while the socket encloses the head of the fastening element and the securing element is arranged inside the socket to hinder removal of the fastening element.

The theft-protecting arrangement makes it more difficult to remove the headlight from the vehicle. The headlight is pivotally arranged to the front part of the vehicle via a hinge mechanism such that the headlight can easily be given service. The hinge mechanism is fastened both to the headlight itself and to the vehicle whereby the headlight can pivot in relation to the vehicle. The headlight can be disassembled from the vehicle by either removing the pin that secures the headlight to the hinge mechanism, or by detaching the whole hinge mechanism from the vehicle by manipulating one or more fastening elements that secures the hinge mechanism to the front part of the vehicle. The protecting device and the securing element are constructed such that when assembled to the hinge mechanism, they simultaneously hinder access to the hinge pin and access to the fastening element. Thereby, neither the hinge pin nor the fastening element can be easily removed and protection against theft is established. The theft-protecting 3 arrangement is rather small and uncomplicated to produce, making it an attractive solution for theft prevention.

According to a second aspect, the disclosure relates to a vehicle headlight comprising a hinge mechanism and a theft-protecting arrangement according to any embodiment of the first aspect.

According to a third aspect, the disclosure relates to a vehicle comprising a vehicle headlight according to any embodiment of the second aspect.

According to a fourth aspect, the disclosure relates to a method for hindering detachment of a vehicle headlight from a vehicle using a theft-protecting arrangement. The method comprises arranging a housing part of a protecting device over a head of a hinge pin of a hinge mechanism. The hinge mechanism comprises a vehicle bracket, a headlight bracket, a vehicle knuckle connected to the vehicle bracket, a headlight knuckle connected to the headlight bracket and the hinge pin inserted through the vehicle knuckle and the headlight knuckle. The headlight bracket is fastened to the vehicle headlight. The protecting device includes a rigid elongated body with the housing part at a first end and a socket at a second end. The method further comprises inserting a body of a fastening element through the socket and through a through hole of the vehicle bracket, and screwing the fastening element to a front part of the vehicle, the socket enclosing the head of the fastening element. The method further comprises inserting a securing element inside the socket to hinder access to the head of the fastening element.

Detailed description Theft of vehicle headlights has increasingly become a problem in many regions.

The herein presented anti-theft arrangement efficiently hinders unauthorized detachment without compromising any function related to the vehicle headlight. As described, the headlight in question is normally pivotally arranged to the front part of the vehicle via a hinge mechanism. The headlight can be removed from the vehicle by either unhinging the headlight (including removing a hinge pin) or by detaching the entire hinge mechanism from the vehicle. The anti-theft arrangement prevents both unhinging and detachment of the entire hinge mechanism. More specifically, the anti-theft arrangement comprises a protecting device with a housing that prevents unhinging and a socket that together with a securing element prevents a hinge fastening element from being removed without special tools and/or knowledge. As long as the protecting device is assembled, the headlight cannot easily be removed from the vehicle. The anti-theft arrangement is easy to assemble and has a low production cost due to its rather straightforward design. ln the following, the anti-theft arrangement will be described in isolation and when assembled to a vehicle headlight and a vehicle with reference to the Figs. 1A to 5.

The anti-theft arrangement 1 comprises two main parts, a protecting device 1a that is illustrated in Figs. 1A-1C and a securing element 1b illustrated in Figs. 2A- 2B. Fig. 1A illustrates the protecting device 1a in an angled front view, Fig. 1B illustrates the protecting device 1a in front view, Fig. 1C illustrates the protecting device 1a from a side view, and Fig. 1D illustrates the protecting device 1a from an angled back view. As can be seen from the figures, the protecting device 1a includes a rigid elongated body 9 with a housing part 5 at a first end 6 and a socket 7 at a second end 8. Hence, the protection device 1a comprises the housing part 5 and the socket 7 joined by the rigid elongated body 9, such that their relative positions are fixed. The housing part 5 is constructed to cover the head 3ca of a hinge pin 3c of a hinge mechanism 3 (Fig. 4). Thereby the housing part 5 enables preventing unhinging of the vehicle headlight 2, hereinafter referred to as "the headlight 2". The housing part 5 is here constructed as a hollow rectangu|ar prism with three sides and a top side, where the body 9 makes up one of the sides. The housing part 5 is here open at its back (Fig. 1D) and downwards (facing the socket 7), but in other embodiments (not shown) it comprises another side at its back and is then not open at its back. The housing part 5 may have other shapes such as hollow cuboid shape, hollow spheric shape or a hollow rectangu|ar prism with four sides and a top side. A housing center|ine 5a defines a center of the housing part 5. The housing part 5 comprises a wall segment 5c that enc|oses an inner space 5b. The wall segment 5c makes up two of the three sides, and the top side, of the hollow rectangu|ar prism. The wall segment 5c is here made from a leaf metal sheet that has been cut to form the sides whereafter it has been bent towards the housing center|ine 5a to form the inner space 5b. However, this is only one example and the housing part 5 may be constructed in various ways. As understood, the housing part 5 is open at one side facing the socket 7 such that it can receive part of or the whole head 3ca of the hinge pin 3c (Fig. 4) in its inner space 5b. Hence, the inner space 5b at least partly corresponds to a size of the head 3ca of the hinge pin 3c such that the housing part 5 can at least partly enclose the head 3ca.

The socket 7 comprises a tubular wall segment that enc|oses an inner space 7e. The inner space 7e is large enough to accommodate a head 4aa of a fastening element 4a, such that the fastening element 4a cannot be easily removed, for example unscrewed if it is a screw, when the securing element 1b is arranged in the socket 7. A longitudinal center of the socket 7 is defined by a symmetrical socket center|ine 7a. The socket 7 further includes a bottom part 7b with a 6 through-going hole 7c. The bottom part 7b seals the socket 7 at one end (back end) except for the through-going hole 7c. Hence, the inner space 7e is enclosed also by the bottom part 7. The hole 7c has a cross-section that is larger than a cross-section of a body 4ab of the fastening element 4a. Thereby, the body 4ab of the fastening element 4a can be inserted into the hole 7a. However, the cross- section of the hole 7c is also smaller than a cross-section of a head 4aa of the fastening element 4a. Thereby the fastening element 4a can be inserted into the hole 7c up until the head 4aa reaches the bottom part 7, and it is made sure that the head 4aa stays within the socket 7. ln other words, in some embodiments, the socket 7 includes a bottom part 7b with a through-going hole 7c having a cross- section larger than the cross-section of a body 4ab of the fastening element 4a but smaller than a cross-section of a head 4aa of the fastening element 4a. The socket 6 will thus enclose the head 4aa in the inner space 7e. ln other words, the socket 6 is constructed to enclose the head 4aa of the fastening element 4a.

The rigid elongated body 9 extends from the housing part 5 to the socket 7. The body 9 is for example made from a leaf metal sheet. The body 9 has a dimension with a dept "d1 " (Fig. 1C) in the direction of the socket centerline 7a and a width "w" (Fig. 1C) perpendicular to the socket centerline 7a. The depth and width have been chosen such that the body 9 becomes rigid and is not easily bent by manpower. As can be seen from at least Fig. 1B, the body 9 has a first bending with an angle ß in a plane defined by the housing centerline 5a and an X-axis perpendicular to both the housing centerline 5a and the socket centerline 7a. The housing centerline 5a and the socket centerline 7a do not cross, they are offset along the X-axis. This means that the housing part 5 is offset from the socket 7 along the X-axis. As can be seen from Fig. 1C, the body 9 has a second bending, or is cut with a second bending, with an angle din a plane defined by the housing centerline 5a and the socket centerline 7a. The housing part 5 is thus offset from the bottom part 7b of the socket 7 in a direction of the socket centerline 7a with a distance The offsetting is chosen and made such that the protecting device 1a will fit the hinge arrangement 3 (Fig. 4). ln some embodiments, the offsetting is also made such that the body 9 covers another fastening element 4b (Fig. 4). As 7 the body 9 is rigid the relation between the housing part 5 and the socket 7 is fix. As can be seen from the figures, the housing part 5 and the socket 7 are perpendicularly arranged to each other. ln other words, the protecting device 1a is constructed such that the housing center|ine 5a of the housing part 5 is perpendicular to the socket center|ine 7a of the socket 7.

The socket 7 is attached to the body 9 for example by welding. The housing part 5 may also be attached to the body 9 by welding. ln other embodiments, the body 9 and the housing part 5 are made from the same piece of leaf sheet. The body 9 and housing part 5 may then be a unitary structure, hence made in one continuous piece of material. To produce such unitary structure, the leaf sheet is first cut or punched into appropriate shape and thereafter bent to form the housing part 5 and the body 9. ln other words, in some embodiments, the housing part 5 is made from a cut and bent leaf sheet. The socket 7 may be made by turning or milling. ln other words, the socket 7 is a machined socket. The protection device 1a may be made of steel. Hence, the body 9, the housing 6 and the socket 7 are all made of steel.

The securing element 1b in Figs. 2A and 2B has a shape of a cap or plug. Fig. 2A illustrates the cap in an angled side view, and the Fig. 2B is a side view of the cap. The cap has a bottom segment 1bb and a wall segment 1ba enclosing an inner space 1bc. The cap has a depth d3 that is smaller than a depth d2 (Fig. 1C) of the socket 6. ln one embodiment the cap is a unitary structure, hence made in one piece. The cap has a circular shape. When inserted into the socket 6, the wall segment of the cap fit snuggly to an inside 7d of the wall segment of the socket 6. ln other words, the securing element 1b is a cap that has a size such that when arranged inside the socket 7 it fits tight to an inside 7d of the socket 7 thereby hindering access to a head 4aa of the fastening element 4a. The bottom segment 1bb then hinders access to an inner space formed between the bottom segment 1bb and the bottom part 7b of the socket 6, and thereby also to the head 4aa of the fastening element 4a. ln an alternative embodiment, the securing element 1b is a pin (not shown) that is inserted inside the socket 6 crosswise the socket 8 centerline 7a such that the pin at both its ends fit snuggly to the inside 7d of the wall segment of the socket 6 and is not easily removed. The pin will then hinder access to the head 4aa of the fastening element 4a. ln other words, the securing element 1b is configured to be arranged inside the socket 6. The securing element 1b is for example made of stainless steel. The securing element 1b is for example made by turning or milling. A removal of the securing element 1b that is needed e.g. if the headlight 2 needs to be changed requires special knowledge or access to special tools.

Fig. 3A illustrates a headlight 2 and a front part of a vehicle 10 before the headlight 2 is attached to the front part. The headlight 2 is configured to be pivotally attached to the front part 11 of the vehicle 10 via a hinge mechanism 3. The hinge mechanism 3 comprises a vehicle bracket 3a and a headlight bracket 3b. The vehicle bracket is 3a arranged to be fastened to the front part 11 of the vehicle 10 via a fastening element 4a. The headlight bracket 3b is fastened to the headlight 2. The fastening of the headlight bracket 3b to the headlight 2 is typically shielded or accommodated in the headlight 2 so that it is not accessible from the outside of the vehicle 10 when the headlight 2 is assembled to the vehicle 10. The headlight bracket 3b is fastened to the headlight 2 at one side of the headlight 2. The hinge mechanism 3 further comprises a vehicle knuckle 3c connected to the vehicle bracket 3a, a headlight knuckle 3d connected to the headlight bracket 3b and a hinge pin 3e inserted through the vehicle knuckle 3c and the headlight knuckle 3d (Fig. 4). The vehicle bracket 3a comprises a first through hole 3e and a second through hole 3f. To assemble the headlight 2 to the vehicle 10, a body 4aa of a fastening element 4a is inserted through the first through hole 3e and further into a corresponding hole 11a in the front part 11 of the vehicle 10 as illustrated with a hatched line. The fastening element 4a is for example a screw that thus is screwed into the vehicle 10 at the hole 11a and thereby attaches the headlight 2 to the vehicle 10. Another body 4ba of another fastening element 4b is inserted through the second through hole 3f and further into another corresponding hole 11b in the front part of the vehicle 10 as illustrated with another hatched line. The other fastening element 4b is for example a screw that 9 is screwed into the vehicle 10 at the hole 11b and thereby further attaches the headlight 2 to the vehicle 10. ln some embodiments, only one fastening element 4a is used. When the headlight 2 is assembled to the vehicle 10 as illustrated in Fig. 3B with one of more fastening elements 4a, 4b, the headlight 2 can be pivotally moved around a pivot axis of the hinge mechanism 3 and thereby the headlight 2 can be access from the inside so it can be serviced, e.g., exchange lamp etc. To fully assemble the headlight 2 to the vehicle, the headlight 2 is screwed with one or more screws at an opposite side of the headlight 2 to the vehicle 10 that are easily accessible from the outside.

Fig. 3C, 3D and 4 illustrate how the theft-protecting arrangement 1 can be assembled to the vehicle 10 for hindering detachment of the headlight 2 from the vehicle 10. Fig. 3D illustrate the arrangement 1 assembled to the vehicle 10 and Fig. 4 illustrates an enlarged view of a part of Fig. 3D with the assembled theft- protecting arrangement 1. A method for hindering detachment of the headlight 2 from a vehicle 10 using the theft-protecting arrangement 1 will now be described with reference to this figure and the flow chart of Fig. 6. ln Fig. 3C, the headlight 2 has already been attached to the vehicle 10 with another fastening element 3b as explained in connection with Fig. 3A. ln other words, in some embodiments, the method comprises attaching S1 the headlight 2 to the vehicle 10 by inserting the body 4ba of the other fastening element 4b through the through hole 11b of the vehicle bracket 3a and screwing the other fastening element 4b to the front part 11 of the vehicle 10. The headlight 2 is now attached to the vehicle 10. However, in some embodiments this step is not needed. The method further comprises arranging S2 the housing part 5 of the protecting device 1a over a head 3ca of the hinge pin 3e of the hinge mechanism 3. Hence, the housing part 5 is placed over and on the head 3ca of the hinge pin 3e. The method further comprises inserting S3 the body 4ab of the fastening element 4a through the socket 7 and through the through hole 3e (Fig. 3A) of the vehicle bracket 3a. The method further comprises screwing S4 the fastening element 4a to the front part 11 of the vehicle 10. The socket 6 is now enclosing the head 4aa of the fastening element 4a. The method further comprises inserting S5 a securing element 1b inside the socket 7 to hinder lO access to the head 4aa of the fastening element 4a. The insertion S5 may include pressing the securing element 1 into the socket 7 until the securing element 1 makes contact with the head 4aa, to provide a tight fit. The insertion may include hammering on the securing element 1b with a hammer or using a certain tool to press the securing element 1b into the socket 7 with a certain force or pressure. The theft-protecting arrangement 1 is now assembled on the hinge mechanism 3 and also on the vehicle 10. ln this assembled state, the housing part 5 covers the head 3ca of the hinge pin 3c to hinder removal of the hinge pin 3c, while the socket 7 encloses the head 4aa of the fastening element 4a and the securing element 1b is arranged inside the socket 7 to hinder removal of the fastening element 4a.

From Fig. 4 it can be seen that the protecting device 1a is constructed such when the protecting device 1a is assembled to the hinge mechanism 3 and a vehicle 1, that is positioned in an upright use position on a flat horizontal surface, the housing centerline 5a of the housing part 5 is vertical and the socket centerline 7a of the socket 7 is horizontal. The housing centerline 5a is further aligned with a pivot axis of the headlight 2, hence a pivot axis of the hinge mechanism 3. The housing centerline 5a is thus aligned with a direction of extension of the hinge pin 3c.

The headlight 2 can still be pivoted via the hinge mechanism 3 even of the theft- protecting arrangement 1 is assembled to the hinge mechanism 3. This is possible by means of the slim design of the protecting device 1a that does not hinder any movement, and because the head 3ca of the pin 3c (Fig. 4) is allowed to move inside the housing part 5. Hence, the theft-protecting arrangement 1 is configured such that when it is assembled on the hinge mechanism 3, pivotal movement of the headlight 2 via the hinge mechanism 3 is still allowed.

As can be seen from Fig. 4, the stiff elongated body 9 of the protecting device 1a lies across the head 4ba of the other fastening element 4b and hinders access to the other fastening element 4b. Thereby the other fastening element 4b cannot ll easily be detached from the vehicle 10 while the protecting device 1 is assembled to the vehicle 10. ln other words, the vehicle bracket Sa is configured to be fastened to a front part 11 of the vehicle 10 via the other fastening element 4b. The rigid elongated body 9 further has an extension constructed to least partly cover a head 4ba of the other fastening element 4b, when the theft-protecting arrangement 1 is assembled to the hinge mechanism 3, to hinder removal of the other fastening element 4b.
