In practice, a vehicle headlamp usually comprises a low-beam module provided with a low-beam reflector and a high-beam module provided with a high-beam reflector.

At present, in the lamps of motor vehicles, by suitably designing the light path, it is possible, for example, to integrate the high beam reflector of the high beam module and the low beam reflector of the low beam module into one large common support; however, in this case, since both the high beam reflector and the low beam reflector are configured to share one aiming (aiming) system, for example, it is necessary to accommodate both the high beam module and the low beam module in a limited installation space with as little space consumption as possible to save space. The large volume of the common support makes it difficult to meet the requirements of such a spatial arrangement, and the provision of such an integrated arrangement of both high-beam and low-beam reflectors entails the risk that the support is susceptible to impacts from the outside and the entire structure vibrates.

To this end, there is a need in the art for a light source assembly comprising a high beam module and a low beam module, with a simple construction, for fitting in the limited space of a lighting and/or signalling system, which is provided with an adjustment function for the respective reflectors, and which is constructed so as to reduce the risk of vibrations and deformations.

Detailed Description

The technical solution of the present disclosure is further specifically described below by way of examples and with reference to the accompanying drawings. In the description, the same or similar reference numerals denote the same or similar components. The following description of the embodiments of the present disclosure with reference to the accompanying drawings is intended to explain the general inventive concept of the present disclosure and should not be construed as limiting the present disclosure. Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments of the disclosure. It may be evident, however, that one or more embodiments may be practiced without these specific details.

In view of the foregoing problems of the prior art, embodiments of the present disclosure propose to utilize the technical concept that one of two ends of a coupling mechanism is fixedly coupled to a first bracket for a first reflector, and the other opposite end is rotatably coupled to a second reflector by means of a spherical kinematic pair, so that the first bracket serves as a common bracket for the first reflector and the second reflector to be coupled to each other integrally, and the adjustment of the relative positioning can be performed by means of the spherical kinematic pair. Thus, embodiments of the present disclosure schematically provide a light reflecting structure of a vehicle lamp, and a motor vehicle for achieving these objects.

Fig. 1(a) schematically shows an exploded perspective view of a light reflection structure 100 in an assembled state in which a first holder 10 and a second reflector 20 are coupled to each other via a coupling mechanism 30; fig. 1(b) shows a schematic structural view illustrating the light reflection structure 100 shown in fig. 1(a) in a front view.

According to one general technical concept of the embodiments of the present disclosure, as shown in fig. 1(a), there is provided a light reflecting structure 100 of a vehicle lamp, including: a first support 10; a first reflector 12 integrated in the first support 10, for example integrally formed with said first support 10; and a second reflecting member 20. And, the first supporter 10 supports the second reflecting member 20.

With the above arrangement, since the second reflecting member 20 is directly supported by the first bracket 10 integrally formed with the first reflecting member 12, the second reflecting member 12 does not require a dedicated bracket, whereby the light reflecting structure for a vehicle lamp reduces required components as a whole, resulting in reduced cost and space saving; and because the first bracket 10 is integrated with the first reflector 12, the connection is more stable and reliable compared with a split connection.

In a further embodiment, for example, the light reflecting structure 100 further comprises a coupling mechanism 30, the coupling mechanism 30 comprising: the three

coupling assemblies

31, 31' or 32 are arranged in a non-collinear arrangement, i.e., they are not aligned in a straight line but arranged in a triangular arrangement as shown in the figure, and are coupled between the first bracket 10 and the second reflector 20, respectively. And, corresponding to three coupling assemblies in a non-collinear arrangement, fig. 3(a) shows a structural schematic view of a first bracket in the light reflecting structure 100 according to one embodiment of the present disclosure in a front view; and fig. 3(b) shows a top view of the first bracket as shown in fig. 3 (a). As shown, the structural features on the first support 10 to be used for coupling with said second reflector 20 via the coupling mechanism 30 are schematically shown. As shown, the three coupling assemblies are fixedly coupled at one end to the engaging

portions

11, 11 ', 11 ″ on the side of the first support 10 facing the second reflector 20, respectively, and rotatably coupled with spherical kinematic pairs provided at the opposite ends to the receiving

structures

21, 21', 21 ″ on the side of the second reflector 20 facing the first support 10, respectively.

In a further embodiment, for example, one of the three coupling assemblies 31 "or 32 is configured with its spherical kinematic pair in a fixed state to effect fixation of the second reflecting member 20 with respect to the first reflecting member 12; and the spherical kinematic pairs of the other two coupling assemblies 31, 31' of said three coupling assemblies are configured to effect vertical and horizontal adjustment, respectively, of the second reflecting member 20 with respect to the first reflecting member 12 by rotation in the vertical and horizontal directions, respectively.

Since the three coupling assemblies are disposed in a non-collinear manner and are respectively coupled to the first bracket 10, a spatial triangular linkage mechanism is substantially formed, and in the case that the spherical pair of one coupling assembly is in a fixed state, the spherical pairs of the other two coupling assemblies can be adjusted in precession directions around the pivot point by taking the spherical pairs as pivot points respectively during respective rotation processes, so as to respectively realize rotation in a vertical direction and rotation in a horizontal direction. Thus, the three coupling assemblies are used to achieve a fixed state, vertical direction rotation, and horizontal direction rotation of the second reflecting member with respect to the first reflecting member, respectively, thereby achieving adjustment of the relative sweeping direction between the respective outgoing light between the first reflecting member and the second reflecting member. Thus, with one of the first and second reflecting members as a reference, discrete adjustment at the three coupling members is achieved with a simple structure, thereby facilitating adjustment of the relative light exit direction of the other reflecting member.

And (4) overall adjustment mode.

FIG. 2(a) schematically illustrates an exploded perspective view of a coupling assembly according to an embodiment of the present disclosure; fig. 2(b) schematically illustrates an exploded perspective view of a coupling assembly according to another embodiment of the present disclosure.

As shown, each coupling assembly comprises, for example: a ball cup 310, 310' and a cap piece 311. The ball cup is for example provided with a ball head at one end and coupled to the first support 10 at the opposite end. The ceiling member 311 includes, for example: a ball socket 3110 at one end of the top cover member and configured to cooperate with the ball head to form a spherical kinematic pair capable of pivoting in place, and a cylindrical protrusion 3111 at the other end of the top cover member opposite to the ball socket 3110 and housed within the second reflector 20.

In one embodiment, for example, the cap member 311 and the second reflector 20 are respectively formed as separate members coupled to each other. Or, in alternative embodiments, for example, the cap 311 is in a single piece with the second reflector 20, for example assembled in a single piece, thereby facilitating subsequent assembly.

By rotatably receiving the ball head in the ball socket, a spherical kinematic pair coupling having a rotational freedom in place (i.e., capable of rotating in place) of the ball socket with respect to the cap member 311 is achieved. Thereby, a light reflecting structure 100 of a vehicle lamp capable of performing angular adjustment of the second reflecting member 20 with respect to the first bracket 10 by means of a spherical kinematic pair coupling is realized. The working principle of the spherical kinematic pair is that the degree of translational freedom in all directions of the spherical kinematic pair is eliminated through the matching between the ball head and the ball socket in the spherical kinematic pair so as to realize the limitation of radial deviation, and the spherical kinematic pair only has the degree of rotational freedom in situ through enabling the ball head to axially rotate around the rotation center of the ball head in the ball socket in situ. With the above arrangement, the assembly between the first support 10 integrated with the first reflector and the second reflector 20 is achieved by means of a spherical kinematic pair and a flexible adjustment of the angles relative to each other can be achieved by a pivot of the spherical pair.

In a further embodiment, as shown, each of the coupling assemblies is fixedly coupled at one end to a joint on a side of the first support 10 facing the second reflector 20, and is pivotably coupled to a receiving structure on a side of the second reflector 20 facing the first support 10 with a spherical kinematic pair at the other end opposite to the one end.

Specifically, for example, as shown in the figure, the first bracket 10 is formed with three engaging

portions

11, 11', 11 ″ in a non-collinear arrangement on a side thereof facing the second reflecting member 20, and the three engaging portions are each arranged, shaped and sized so as to be fitted to the three coupling assemblies 31, respectively; 31'; 31 ", 32 of the ball socket 310, 310'; and the second reflector 20 has three receiving

structures

21, 21 ', 21 "formed on a side thereof facing the first support 10 in a non-collinear arrangement, and the three receiving

structures

21, 21', 21" are respectively arranged, shaped and sized to receive the three coupling assemblies 31 in alignment; 31'; 31 ", 32, and a cylindrical protrusion 3111 of the cap member 311.

With this particular arrangement, in particular, the three coupling assemblies of the coupling mechanism 30 are respectively coupled with the three joints of the first support 10 and with the three receiving structures of the second reflector 20, and since the three connecting assemblies, the three joints and the three receiving structures are all in a non-collinear arrangement, such as the illustrated triangular arrangement, a secure coupling of the first support 10 with the second reflector 20 via the coupling mechanism 30 is achieved. The first bracket 10 and the second reflector 20 integrated with the first reflector are coupled to each other by means of the coupling mechanism 30, whereby the first bracket 10 serves as a mounting frame for the first reflector, thereby achieving integrated coupling and fixing of the first reflector and the second reflector in the vehicle lamp in a limited mounting space; and the relative positioning of the first and second reflectors can be adjusted by a revolutionary spherical kinematic pair formed at said other end of each coupling assembly coupled between the first and second supports, respectively, to the second reflector to facilitate respective movable local adjustment positioning, and the assembly thus coupled is configured to be sufficiently strong to be suitable for reducing the risk of vibration and deformation.

More specifically, as shown, particularly in the case of fig. 2(b), the same components are also illustrated as in the other related figures, for example, at least two coupling assemblies 31, 31 'of the three

coupling assemblies

31, 31', 32 are first coupling assemblies, each of which includes the cap member 311 and a first ball mount 310 serving as the ball mount, the first ball mount 310 includes a key 3102 and a screw 3101, the key 3102 having a threaded hole 31021 formed therein, the screw 3101 includes: a ball head 31001 located at a first end of the threaded member 3101; a pin 31002 at a second end opposite the first end and shaped and sized for insertion into the threaded hole 31021; and a threaded body portion 31003 located between the ball head 31001 and the pin 31002, having external threads configured to engage with the internal threads of the threaded hole 31021 to screw the ball head 31001 against the inner wall of the socket. And the other coupling assembly 32 of the three coupling assemblies (31; 31 '; 32) is a second coupling assembly comprising a cap member 311 and a second ball socket 310 ' acting as the ball socket, the second ball socket 310 ' comprising: a seat main body portion 3101A and a second ball head 31011A formed integrally with and protruding from the seat main body portion 3101A and configured to form the spherical kinematic pair with the ball and socket of the overcap 311 to be pivotably coupled to each other in situ.

In the embodiment described above, in the first coupling assembly, the integral fixed coupling of the screw 3101 and the key 3102 is achieved by inserting the pin of the screw 3101 and the intermediate portion having the external thread into the threaded hole of the key 3102. In the second coupling assembly, the ball socket 310' is fixedly coupled to the corresponding engaging portion 11 ″ of the first supporter 10 and received in the corresponding receiving structure 21 ″ of the second reflector 20 with the cylindrical protrusion 3111 of the top cover 311 of the second coupling assembly, thereby realizing a specific light reflection structure 100 capable of performing an angular adjustment of the first supporter 10 with respect to the second reflector 20 using a spherical kinematic pair coupling.

In fact, in the present embodiment as shown in fig. 2(b), the light reflection structure has not only relative angle adjustment achieved by the in-situ rotational freedom of the spherical kinematic pair. By means of the first bracket 10 fixedly coupled with the other two coupling assemblies, i.e., the two first coupling assemblies 31, 31 ', and the second reflecting member 20 to which the two first coupling assemblies are respectively pivotally coupled, and with the second coupling assembly 32 coupled between the first bracket 10 and the second reflecting member 20 in a fixed position as a pivot point, combined motions of pivoting about the second coupling assembly 32 and pivoting about a ball pivot center, and axial displacement of the ball following the screw feeding, respectively, can be actually generated at the joint of each of the two first coupling assemblies 31, 31' and the second reflecting member 20 without generating displacement at the second coupling assembly 32, thereby achieving adjustment of displacement and angle between the first bracket 10 and the second reflecting member 20 with a simple structure; and, when the ball head is extended and retracted along with the screw advance of the screw main body portion of the screw member, it is driven to move back and forth along the length direction of the screw member, i.e., the axial direction of the ball head, while being rotatably pushed against the inner wall of the ball socket, thereby adjusting the displacement and rotation of the second reflecting member 20 with respect to the first bracket 10, thereby adjusting the high beam and the low beam to achieve the relative displacement and angle adjustment therebetween, respectively.

The embodiment of the present disclosure utilizes the above-mentioned motion characteristics of the spherical kinematic pair formed by the ball of the screw 3101 and the ball socket of the cap 311, so as to convert the screw feeding motion of the middle portion of the screw 3101 integrally coupled with the ball and having the external thread into the rotation of the cap 311 and the second reflector (e.g., the high beam reflector) coupled thereto, and can realize self-locking at any position, thereby ensuring the positioning accuracy of the second reflector with respect to the first bracket fixedly coupled with the screw 3101.

In addition, since the second coupling component does not have a thread engagement feature, the second coupling component does not push the ball against the ball socket by the thread feeding motion to realize the displacement adjustment function between the two brackets, and the second coupling component 32 does not displace and does not interfere with the adjustment of the other two first coupling components 31 and 31', so that the optimized adjustment control is realized.

In an alternative embodiment of the present disclosure, as shown for example in fig. 2(a), each of the three

coupling assemblies

31, 31', 31 "is configured to couple the second reflector 20 to the first bracket 10 in a displaceable manner in at least one of the horizontal and vertical directions.

More specifically, as shown in fig. 2(a), for example, each of the three

coupling assemblies

31, 31', 31 ″ is a first coupling assembly, each of which includes the cap member 311 and a first ball seat 310 serving as the ball seat, the first ball seat 310 includes a key 3102 and a screw 3101, the key 3102 has a threaded hole 31021 formed therein, and the screw 3101 includes: a ball head 31001 located at a first end of the threaded member 3101; a pin 31002 at a second end opposite the first end and shaped and sized for insertion into the threaded hole 31021; and a threaded body portion 31003 located between the ball head 31001 and the pin 31002, having external threads configured to engage with the internal threads of the threaded hole 31021 to screw the ball head 31001 against the inner wall of the socket. Thereby, another specific light reflecting structure 100 capable of performing angular adjustment of the first support 10 with respect to the second reflecting member 20 using a spherical kinematic pair coupling is realized.

Thus, with the coupling mechanism including three first coupling components as shown in fig. 2(a), the key 3102 of each first coupling component is fixedly coupled to the corresponding engaging portion of the first bracket 10, and the columnar protrusion 3111 of the top cover piece 311 of each first coupling component is accommodated in the corresponding accommodating structure of the second reflector 20, thereby realizing a headlamp mounting structure 100 capable of angular adjustment of the first bracket 10 with respect to the second reflector 20 with a spherical kinematic pair coupling. The working principle of the spherical kinematic pair is that the degree of translational freedom in all directions of the spherical kinematic pair is eliminated through the matching between the ball head and the ball socket in the spherical kinematic pair so as to realize the limitation of radial deviation, and the spherical kinematic pair only has the degree of rotational freedom in situ through enabling the ball head to axially rotate around the rotation center of the ball head in the ball socket in situ. And, when the ball head is extended and retracted along with the screw advance of the screw main body portion of the screw member, it is driven to move back and forth along the length direction of the screw member, i.e., the axial direction of the ball head, while being rotatably pushed against the inner wall of the ball socket, thereby adjusting the displacement and rotation of the second reflecting member 20 with respect to the first bracket 10, thereby adjusting the high beam and the low beam to achieve the relative displacement and angle adjustment therebetween, respectively. As in the embodiment shown in fig. 2(a), not only the relative angular adjustment of the spherical pairs, but also the adjustment of the relative displacement can be achieved separately at the three first coupling assemblies, giving more flexible adjustment capabilities.

Various exemplary embodiments of the present disclosure are specifically explained below.

In an embodiment according to the present disclosure, as shown in fig. 2(a) and 2(b), for example, the coupling mechanism 30 includes three

coupling assemblies

31, 31', 31 "(or 32) therein, each including, for example: a ball mount 310, 310 ', and a cap member 311 that mates with the ball mount 310, 310' in a spherical kinematic pair. Wherein the cap member 311 has a ball socket 3110, and an end of the ball socket 310, 310 'to be joined to the cap member 311 is formed in a ball head 31001 and the ball head 31001 is configured to be rotatably received within the ball socket 3110 of the ball socket 310, 310' to form a rotatable coupling.

In a further embodiment of the present disclosure, for example, as shown in fig. 2(a) and 2(b), at least two first coupling assemblies 31, 31' are included in the three coupling assemblies of the coupling mechanism 30. For example, as shown in fig. 2(a), the three coupling assemblies of the coupling mechanism 30 are the same three

first coupling assemblies

31, 31', 31 "; as shown in fig. 2(b), the three coupling assemblies of the coupling mechanism 30 include the same two first coupling assemblies 31, 31' and a different second coupling assembly 32.

In a particular embodiment, for example, as shown in fig. 2(a), in each of said

first coupling assemblies

31, 31 ', 31 ″ as said coupling assembly, and as shown in fig. 2(b), in each of said first coupling assemblies 31, 31' and different second coupling assemblies 32 as coupling assemblies, said cap 311 is, for example, a table provided with a cylindrical protrusion, for example, insert-fitted into a receiving structure provided on a side of said second reflector 20 facing said first support 10, to achieve a secure coupling of said cap 311 and said coupling assembly comprising said cap 311 with respect to said second reflector 20; preferably, the cylindrical protrusion is formed with an external thread, for example, and thereby acts as a nut to be screwed into the receiving structure of the second reflector 20 provided with an internal thread, to achieve a secure and detachable threaded coupling of the cap 311 and the coupling assembly comprising the cap 311 with respect to the second reflector 20. And the table body has the ball socket 3110 formed therein on a side opposite the cylindrical protrusion, the ball socket 3110 being adapted to receive the ball head 31001 and enable the ball head 31001 to rotate in the ball socket 3110.

In one specific embodiment, for example, as shown in fig. 2(a), in each of the

first coupling assemblies

31, 31', 31 ″ as the coupling assembly, the ball mount 310 includes, for example: a threaded member 3101, and a key 3102, wherein the key 3102 has a threaded hole 31021 formed therein (e.g., centrally disposed), the threaded member 3101 further comprising: a first end 31001 formed as the ball head 31001 and configured to be rotatably received within the socket 3110 of the cap 311; a second end 31002 opposite to the first end 31001, formed as a pin, for example, a pin having a rectangular cross section and configured to be shaped and sized to be inserted into the threaded hole 31021 of the key 3102; and a threaded body portion 31003 interposed between the first end 31001 and the second end 31002 and provided with an external thread configured to be adapted to be engaged with an internal thread of the threaded hole 31021 for screw feeding.

With this arrangement, the threaded element 3101 is inserted with the second end 31002 and the threaded body portion 31003 into the hole 31021 of the key 3102 to form a fixed coupling that is form-fitting to each other, thereby forming an integral ball cup 310. And is freely rotatably received in the cap member 311 by a first end of the screw member 3101 in the ball head seat 310, thereby forming a

first coupling assembly

31, 31', 31 ″ having a spherical kinematic pair at an end to be coupled with the second reflective member 20. Thereby, once assembled, said cap 311 and said screw 3101, and thus said headstock 310, are engaged with each other by means of a rotatable ball-and-socket coupling, providing only rotational freedom in situ at the ball-and-socket coupling, while constraining translational freedom in all directions there.

In a further embodiment, said second end 31002 of said screw 3101 is formed as a pin, for example a pin of rectangular cross-section, shaped and sized to be pin-fit into the engagement portion of said first bracket 10 to be coupled with said coupling assembly, for example tightly fit into a pin hole formed therein by means of a pin-pin hole shape fit, whereby, upon assembly, said key 312 and said screw 310 clampingly engage each other by means of a pin-pin hole shape fit to form an integral socket 310 where all translational and rotational degrees of freedom are constrained, thereby achieving a non-disengageable coupling with said key 3102 at the pin 31002 of the screw 3101.

In an alternative embodiment, for example as shown in fig. 2(b), the coupling assembly comprises, in addition to two of the first coupling assemblies 31, 31', an additional second coupling assembly 32 to serve as a replacement for one of the first coupling assemblies 31 ". In the second coupling assembly 32, the ball seat 310' includes, for example: a seat body portion 3101A, and a second ball head 31011A protruding from the seat body portion 3101A, the second ball head 31011A being integrally formed with the seat body portion 3101A. With this arrangement, the second ball head 31011A in the ball head seat 310' is freely rotatably received in the cap member 311, thereby forming the second coupling assembly 32 having a spherical kinematic pair at one end to be joined with the second reflective member 20. Thereby, once assembled, said cap 311 and said ball cup 310' are joined to each other by means of a rotatable ball-and-socket coupling, so that there is only rotational freedom in place at the ball-and-socket coupling, while translational freedom in all directions is constrained there.

As an exemplary embodiment, for example, as shown in fig. 3(a) to 3(c), in the first bracket 10 fitted with each of the coupling assemblies, specifically, for example, on the side of the first bracket 10 facing the second reflector 20, three grooves or holes (for example, keyways or keyholes for fitting with keys) in a non-collinear arrangement, i.e., in a triangular arrangement, are provided to serve as the

joints

11, 11', 11 "; and each coupling component of the coupling mechanism 30 is, for example, the same three

first coupling components

31, 31 ', 31 "as shown in fig. 2(a), their respective keys 3102 snap-fit into the three keyways or

keyholes

11, 11', 11", respectively, for example, in a form-fitting manner.

Further, for example, in each of the engaging

portions

11, 11 ', 11 ", for example, a central hole 111 is further provided, the central hole 111 being, for example, centrally provided in each of the engaging

portions

11, 11', 11", and being, for example, a smooth hole, or a threaded hole, or a partially threaded hole, the partially threaded hole being, for example, a pin hole in a front section (located near the first bracket 10 of the key 3102) and a threaded hole in a rear section (located away from the first bracket 10 of the key 3102); and is shaped and sized, for example, to allow the screw 3101 of each of the

first coupling assemblies

31, 31', 31 "to enter, after passing through the threaded hole 31021 of the key 3102, at least with a pin, for example, of rectangular cross-section, at the second end 31002; of course, alternatively, the threaded body portion 31003 immediately adjacent the pin 31002 may also enter partially into the central bore 111, for example. Also, it is more preferable that, for example, a groove 1110 is further formed transversely through the central hole in the width direction of each of the engaging

portions

11, 11', 11 ″ perpendicular to the respective length direction for the purpose of forming a pin-and-groove joint when a pin is inserted into the groove and is held in place therein.

Thus, by snapping the key 3102 into the corresponding key way or

keyhole

11, 11', 11 ", and then passing the threaded member 3101 through the threaded hole 31021 of said key 3102 with the pin at its second end entering into said central hole 111 and being held in place by said slot 1110, a secure fit and fixation is created between the coupling mechanism 30 and the first bracket 10, thereby eliminating all translational and rotational freedom at the junction thereof. Thereby, a secure fit is formed between the coupling mechanism 30 and the first bracket 10.

Preferably, for example, as shown in fig. 1(a), 3(b) and 3(c), of three

engaging portions

11, 11 ', 11 ″ formed on a side (i.e., the illustrated upper surface) of the first bracket 10 facing the second reflector 20 in a non-collinear arrangement, each of the engaging portions configured to receive the first coupling component (e.g., at least two engaging portions 11 and 11' to be engaged with the key 3102) is formed as a counter bore in a rectangular parallelepiped depression shape as shown in the drawing to serve as the key groove/key hole. Accordingly, the key 3102 is, for example, block-shaped as shown and is shaped and sized to fit within the keyway or keyhole.

Or, as an alternative exemplary embodiment, in the first bracket 10 cooperating with each of said coupling assemblies, in particular, for example, on the side of said first bracket 10 facing said second reflecting member 20, three slots or holes in a non-collinear arrangement, i.e. in a triangular arrangement, are still provided to act as the

aforementioned junctions

11, 11', 11 "; and the respective coupling components of the coupling mechanism 30 are, for example, the keys 3102 of the two first coupling components 31, 31 'and the different second coupling component 32 as shown in fig. 2(b), and the keys 3102 of the first coupling components 31, 31' and the seat main body portion 3101A of the ball seat 310 'in the second coupling component 32 are, for example, snap-fitted into the three

engaging portions

11, 11', 11 ″ embodied as grooves or holes, respectively, in a form-fitting manner. For example, the joint portions 11 and 11' may further include, for example, the center hole 111; and more preferably, the central hole 111 is also provided with a slot part transversely penetrating through the central hole as described above, so as to be used for forming a combination of the pin and the slot part when the pin is inserted into the slot part and clamped in place in the slot part, and the same technical effects are achieved, and are not described herein again.

In further alternative embodiments, for example, since the threaded hole 31021 is provided as a blind hole, or the length of both the threaded main body portion 31003 and the pin 31002 of the screw 3101 is smaller than the depth of the threaded hole 31021, the pin 31002 of the screw 3101 is inserted into the threaded hole 31021 formed in the key 312 but does not extend beyond the key 312 during the fitting of the key 3102 of the first coupling component of the coupling mechanism 30 into the key groove or key hole serving as the engaging portion 11, 11' and/or 11 ″, a guide projection 31023 is additionally provided on the side of the key 3102 to be engaged to the key groove or key hole as shown in fig. 2(a) and 2 (b); and correspondingly, the central hole 111 in the engaging portion 11, 11' and/or 11 "of the first bracket acts as a guide hole, and the central hole 111 is shaped and dimensioned to receive the guide protrusion, and the guide hole is arranged to align with and receive the guide protrusion with the key 3102 aligned with the keyway or keyhole. Whereby the guide hole and the guide protrusion cooperate to guide during insertion of the key 3102 of the coupling assembly into the keyway or keyhole to facilitate smooth insertion; and the guide projection enters the central bore 111 and is held in place by the slot portion, thereby eliminating all translational and rotational degrees of freedom at the junction of the two. Thereby, a firm fit and fixation is formed between the coupling mechanism 30 and the first bracket 10.

In a further alternative embodiment, for example, in the case where each coupling component of the coupling mechanism 30 is, for example, the key 3102 of two first coupling components 31, 31 'as shown in fig. 2(b), and the second coupling component 32 different therefrom, in the case where the seat main body portion 3101A of the ball seat 310' of the second coupling component of the coupling mechanism 30 is not configured to be capable of being directly in firm form-fit with the groove or hole serving as the engaging portion 11 "(for example, both are merely clearance-fit or transition-fit), a second guide protrusion is additionally provided on the side of the seat main body portion 3101A to be engaged to the groove or hole 11" as shown in fig. 2 (b); and correspondingly, the engaging portion 11 "of the first bracket is also additionally provided with a second guide hole shaped and sized to receive the second guide projection, and arranged to align with the second guide projection with the seat body portion 3101A aligned with the slot or hole 11". Thus, the guide hole and the guide protrusion cooperate to guide during insertion of the seat body portion 3101A of the second coupling assembly into the slot or hole 11 "to facilitate smooth insertion.

Or, in a further alternative embodiment, still in case each coupling component of the coupling mechanism 30 is, for example, a key 3102 of two first coupling components 31, 31 'as shown in fig. 2(b), and a second coupling component 32 different therefrom, the first bracket 10 is still provided with three engaging portions in a non-collinear arrangement, i.e. in a triangular arrangement, on the side facing the second reflector 20, the two engaging portions 11, 11' are again keyways or keyholes as previously described, while the other engaging portion 11 "is a boss, or a flat portion formed with a boss; correspondingly, the second coupling assembly 32 in the coupling mechanism 30 shown in fig. 2(b) does not directly engage the other engaging portion 11 "with the seat main body portion 3101A of the ball seat 310' thereof, but instead forms a dimple in the seat main body portion 3101A configured to mate with the boss, or the flat portion formed with the boss. Thereby, while the keys 3102 of the two first coupling components 31, 31 'enter the two engaging portions 11, 11', respectively, the other engaging portion 11 ″ in the form of a boss, or a flat portion formed with a boss, is snap-fitted into the recess of the seat main body portion 3101A of the ball cup 310 'of the second coupling component 32, thereby guiding the other engaging portion 11 ″ of the first bracket 10 into the recess in the seat main body portion 3101A of the ball cup 310' during engagement of the second coupling component 32 with the first bracket 10, and forming a secure fit between the coupling mechanism 30 and the first bracket 10.

In a further embodiment, the engaging portions 11, 11', and/or 11 ″ are further formed with, for example, retaining recesses 112 respectively located on both sides of the central hole 111 in the respective lengthwise directions, the retaining recesses 112 preferably being arranged, for example, symmetrically with respect to the central hole. And correspondingly, as shown in fig. 2(a) and/or 2(b), a side surface of the key 3102 of each of the first coupling components 31, 31 ', and/or 31 ″ facing the engaging part is also formed with a limit protrusion 31022 arranged in alignment with the limit recess 112, respectively, whereby, when the first coupling components 31, 31 ', and/or 31 ″ are guided into position in the engaging parts 11, 11 ', and/or 11 ", respectively, since redundant limit is achieved at two positions where the limit recess 112 and the limit protrusion 31022 on both sides of the central hole 11 are mated in pairs, any translational and rotational freedom at the engaging position of the two is more securely cancelled, and displacement or misalignment is avoided.

In a still further embodiment, in the case where each coupling component of the coupling mechanism 30 is, for example, a key 3102 of two first coupling components 31, 31' as shown in fig. 2(b), and a second coupling component 32 different therefrom, the engaging portion 11 ″ corresponding to the second coupling component 32 is, for example, further formed with second limit recesses located on both sides of the second guide hole, which are preferably, for example, symmetrically arranged with respect to the second guide hole. And correspondingly, a side surface of the second coupling component 32 facing the joint part 11 'is formed with second limit protrusions respectively aligned with the second limit recesses, thereby, when the second coupling component 32 is guided to the inner position of the joint part 11', as redundant limit is realized at two positions where the second limit recesses respectively positioned at two sides of the second guide hole are matched with the second limit protrusions in pairs, any translational freedom and rotational freedom at the joint position of the two are more firmly and reliably cancelled, and displacement or dislocation is avoided.

In addition, other embodiments of the present disclosure include, but are not limited to, that the second limiting recess may be replaced by a second limiting protrusion, and the second limiting protrusion may also be replaced by a second limiting recess, which performs a similar redundant limiting function, and is not limited herein.

In a still further embodiment, in the case where each coupling component of the coupling mechanism 30 is, for example, a key 3102 of two first coupling components 31, 31' as shown in fig. 2(b), and a second coupling component 32 different therefrom, the engaging portion 11 ″ corresponding to the second coupling component 32 is, for example, further formed with limit bosses on both sides thereof, which are preferably, for example, symmetrically arranged with respect to the bosses. And correspondingly, a side surface of the second coupling component 32 facing the joint part 11 ″ is formed with limit recesses respectively aligned with the limit bosses, thereby, when the second coupling component 32 is guided to the inner position of the joint part 11 ″, since redundant limit is realized at two positions where the limit bosses respectively located at both sides of the boss are paired with the limit recesses, any translational freedom and rotational freedom at the joint position of the two are more firmly and reliably cancelled, and displacement or dislocation is avoided.

In addition, other embodiments of the present disclosure include, but are not limited to, that the limiting boss may be replaced by a limiting recess, and the limiting recess may also be replaced by a limiting boss, which plays a similar redundant limiting role, and is not described herein again.

As an alternative or additional embodiment, a stop feature is also provided similarly, for example on the other side of the first and/or second coupling assembly opposite the above-mentioned stop feature; correspondingly, a matched limit feature is correspondingly arranged on the surface of the second reflection piece facing to the other side of the first coupling component and/or the second coupling component, so that a similar redundant limit effect is achieved, and further description is omitted here.

And, fig. 4(a) illustrates a schematic structure of a second reflector in the light reflection structure 100 according to an embodiment of the present disclosure in a front view; FIG. 4(b) shows a top view of the second reflector shown in FIG. 4 (a); fig. 4(c) shows a perspective view of the second reflecting member shown in fig. 4 (a). As shown, the structural features on the second reflector 20 to be used for coupling with the first support 10 via the coupling mechanism 30 are schematically shown.

For example, as shown in fig. 4(a) to 4(c), correspondingly, the second reflector 20 is also provided with three receiving structures 21, 21 ', 21 ″ in a non-collinear arrangement, for example in a triangular arrangement as shown in the figure, on the side facing the first support 10, and the receiving structures 21, 21', 21 ″ are arranged and shaped and sized to receive the top cover member 311 of the three coupling components 31, 31 ', 31 ″ respectively in alignment, for example, the receiving structures 21, 21', 21 ″ are embodied as hollow columns respectively provided with counterbores (for example, arranged centrally) as shown in the figure, and the respective counterbores are shaped and sized to receive the cylindrical protrusions 3111 of the corresponding top cover member 311, and for example, preferably, the counterbores of the hollow columns serving as receiving structures are provided with internal threads, for example, and the cylindrical protrusions 3111 are correspondingly formed with external threads in threaded engagement with the internal threads, whereby the top cover 311 acts as a screw cap to screw into the inner threaded counterbore of the second reflector 20 to enable a secure and detachable threaded coupling of the top cover 311 and the coupling assembly comprising the top cover 311 and thus the coupling mechanism 30 relative to the second reflector 20.

Thereby, a firmly fixed fit between the second reflective element 20 and the coupling means 30 comprising the three coupling assemblies is facilitated, either by means of a direct form fit or by means of e.g. an internal-external thread engagement.

By providing as above, once assembled, said cap 311 and said screw 3101 are joined to each other by means of a rotatable coupling between ball and socket (i.e. a coupling of a spherical kinematic pair), so that there is only a rotational freedom in place at the ball-socket coupling, while there is a translational freedom constrained in all directions. And since the respective coupling assemblies (

first coupling assembly

31, 31', 31 ″ and second coupling assembly 32) are respectively accommodated with the top cover 311 in the accommodating structure of the second reflecting member 20, such as the hollow column 21, and since the respective coupling assemblies have been fixedly coupled to the first bracket 10, the first bracket 10 and the second reflecting member 20 are coupled to each other via the respective coupling assemblies. Due to the spherical kinematic pair, the rotatable position adjustment of the second reflecting member 20 relative to the coupling mechanism 30 can be realized, and further, the relative position adjustment of the second reflecting member 20 relative to the first support 10 fixedly coupled with the coupling mechanism 30 by means of the coupling mechanism 30 can be realized.

In fact, in the present embodiment as shown in fig. 2(b), by means of the first bracket 10 fixedly coupled with the other two coupling assemblies, i.e., the two first coupling assemblies 31, 31 ', and the second reflecting member 20 to which the two first coupling assemblies are respectively pivotally coupled, and with the second coupling assembly 32 coupled between the first bracket 10 and the second reflecting member 20 at a fixed position as a pivot point, combined motions of pivoting about the second coupling assembly 32 and pivoting about a ball pivot center, respectively, and axial displacement of the ball with screw feeding can be actually produced at the joint of each of the two first coupling assemblies 31, 31' and the second reflecting member 20, without producing displacement at the second coupling assembly 32, thereby achieving adjustment of displacement and angle between the first bracket 10 and the second reflecting member 20 with a simpler structure with respect to fig. 2(a), and the second coupling assembly 32 does not displace itself and thus does not interfere with the adjustment of the other two first coupling assemblies 31, 31', thereby achieving an optimized adjustment control.

Of course, the aspects of the present disclosure are not limited thereto. For example, in an additional embodiment, the hollow cylinder of the second reflector, which acts as the receiving

structure

21, 21', 21 ", is provided with, for example, longitudinal ribs outside, so that the mechanical strength of the joint is increased.

In the embodiment according to the present disclosure, the first reflection member 12 provided on the first bracket 10 is, for example, a Low Beam (LB) reflection member, and the second reflection member on the second reflection member 20 is, for example, a High Beam (HB) reflection member. In one example, the low beam reflector is, for example, a parabolic reflector, but the invention is not limited thereto, and other forms of reflectors known in the art that can achieve the above-described reflective function may be employed, such as an elliptical reflector, or a reflector having a more complex curved shape. In one example, the high beam reflector is, for example, an ellipsoidal reflector, but the present invention is not limited thereto, and other types of reflectors known in the art that can achieve the above-described reflection function may be adopted, such as a parabolic reflector, or a reflector having a more complex curved shape.

It should be noted that the parabolic reflector and the elliptic reflector do not mean that the reflector has to have a complete paraboloid or an elliptic surface, but only need to include a part of the paraboloid or the elliptic surface to realize the reflecting function.

By this arrangement, by virtue of the fact that the three coupling assemblies of the coupling mechanism 30, each provided with a spherical kinematic pair coupling, are coupled between the first bracket 10 and the second reflecting member 20 at three local positions, respectively, a reliable coupling and a facilitated relative positioning and angular adjustment between the first bracket 10 and the second reflecting member 20 are achieved with a more simplified structure and a lighter weight, and with less space occupation, facilitating positioning operations and adjustments within a relatively small installation space, compared to the common bracket of the related art of larger volume.

According to another aspect of the embodiments of the present disclosure, there is provided a vehicle lamp, for example, as shown in the drawing, including: a vehicle body 50; 50'; 50 "according to the light reflecting structure 100 previously described; and a headlamp housed in the light reflecting structure 100, including a light source 40.

The vehicle lamp, including the light reflection structure 100, thus obtains the technical effects as described above, and has all the advantages of the light reflection structure 100, which will not be described herein again.

According to still another aspect of an embodiment of the present disclosure, as shown in fig. 5 for example, there is also provided a motor vehicle including: a vehicle body; and a lamp according to the preceding mounted to the body (i.e. to the body at the location 50; 50'; 50 ") where the lamp is to be mounted.

In a further embodiment, to achieve coupling of the vehicle lamp to the location 50 on the vehicle body where the vehicle lamp is to be mounted; 50'; 50 ", for example, the first bracket 10 further comprises a second coupling mechanism 60, the second coupling mechanism 60 being configured for connecting to a portion 50 of the vehicle body where a lamp is to be mounted; 50'; 50 "and includes: a portion 50 in non-collinear arrangement and respectively coupled to the first bracket 10 and the vehicle body where the lamp is to be mounted; 50'; 50 "; 61'; 61". And, the three coupling assemblies are coupled to the portion 50 of the vehicle body where the lamp is to be mounted, respectively, with threaded ends (shown as respective upper ends); 50'; 50 ″ and are respectively accommodated in the portions 50 of the first bracket 10 facing the vehicle lamp to be mounted on the vehicle body with non-threaded ends (shown as respective lower ends) opposite to the threaded ends; 50'; three second engaging

portions

13, 13', 13 "on one side of 50".

In more specific embodiments, for example, the three coupling assemblies 61; 61'; the threaded ends of 61 "are screwed in a thread-fitting manner into the three

second engagement portions

13, 13', 13", respectively. And, for example, the three coupling assemblies 61; 61'; 61 "is accommodated in the body in a snap-fit manner at its non-threaded end, and the other two coupling assemblies 61'; 61 "are each coupled at their non-threaded ends to the body in such a way as to be able to translate along a single linear direction.

With the above coupling arrangement, it can be ensured that the vehicle lamp is detachably and reliably coupled to the vehicle body via the first bracket 10 thereof via the second coupling mechanism 60 at three locations that are not collinear, respectively.

Since the motor vehicle includes the aforementioned lamp, the technical effects of the light reflecting structure 100 and the lamp as described above are obtained, and will not be described in detail herein.

Although the present invention has been described in connection with the accompanying drawings, the embodiments disclosed in the drawings are intended to exemplify preferred embodiments of the present invention, and should not be construed as limiting the present invention. It would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
