Description

Technical Field

[0001] The present application relates to the technical field of light source reflection, and in particular to a light reflection component and a method for using the same and a vehicle. Background Art

[0002] Light reflection systems are often used in the technical fields of automobiles, solar cells, lighting devices, etc. Light reflection systems are usually formed by combining multiple groups of light reflection components. The light reflection components at least include a light source and a reflector. The light source and the reflector need to have high positioning accuracy to meet the reflection requirements of the system.

[0003] Due to factors such as the structure of the light source, the reflector usually cannot be directly connected and fixed to the light source and needs to be transferred and fixed through a connecting device. The existing connecting device lacks precise positioning function, and it is difficult to adjust the relative position of the light source and the reflector to adapt to the position changes between the two, which makes it easy to generate angle errors and position errors between the light source and the reflector, affecting the reflection control accuracy. Summary of the invention

[0004] The embodiments of the present application provide a light reflecting assembly, a method for using the assembly, and a vehicle, which can achieve fixation between a light source and a reflector and adaptation of six degrees of freedom in space, facilitate adjustment of the positioning relationship between the light source and the reflector, and improve the positioning accuracy of the light source and the reflector as well as the reflection control accuracy.

[0005] In a first aspect, an embodiment of the present application provides a light reflection assembly, including: a light source, a reflector, a fixed axis, a connecting member, and an adjustment mechanism;

[0006] The fixed shaft is fixedly connected to the reflector, and the connecting member is connected to the light source; the connecting member is provided with a first through hole, the fixed shaft is passed through the first through hole, a gap is provided between the fixed shaft and the inner wall surface of the first through hole, and a spherical matching structure is formed between the adjustment mechanism and the connecting member;

[0007] The spherical mating structure enables the fixed shaft and the connecting member to have at least three directions of rotational freedom along the spherical direction; the clearance and the adjusting mechanism cooperate to enable the fixed shaft and the connecting member to have at least two directions of planar freedom along the direction perpendicular to the axial direction of the fixed shaft; the adjusting mechanism and the fixed shaft cooperate to enable the fixed shaft and the connecting member to have at least one direction of linear freedom along the axial direction of the fixed shaft.

[0008] It can be understood that the adjustment mechanism includes a free state and a locked state. In the free state, the connecting member and the fixed shaft are slidably connected, and the adjustment mechanism is used to move to different positions along the axial direction of the fixed shaft and switch to the locked state. In the free state, the connecting member can move relative to the fixed shaft, specifically, the connecting member can slide along the axial direction of the fixed shaft, and the adjustment mechanism can move along the axial direction of the fixed shaft to lock the connecting member in a specific position, so that the position of the connecting member and the fixed shaft is relatively fixed.

[0009] It can be understood that the connection between the reflector and the light source is achieved through the connecting parts and the fixed axis, and the angle and position relationship between the reflector and the light source is adjusted through the adjustment mechanism, so as to achieve the adaptation of the reflector and the light source in six degrees of freedom in space, which is convenient for adjusting the positioning relationship between the reflector and the light source.

[0010] In a possible implementation, the adjustment mechanism includes a first adjustment member and a second adjustment member, and the first adjustment member and the second adjustment member are respectively located on both sides of the connecting member along the axial direction of the first through hole to clamp and fix the connecting member.

[0011] It can be understood that the first adjusting member and the second adjusting member are used to clamp and fix the connecting member when the adjusting mechanism is in a locked state.

[0012] In a possible implementation, the first adjusting member is provided with a first contact surface, the second adjusting member is provided with a second contact surface, the connecting member is provided with a first surface for at least partially contacting the first contact surface, and the connecting member is provided with a second surface for at least partially contacting the second contact surface;

[0013] The first contact surface and / or the first surface is spherical, and the second contact surface and / or the second surface is spherical.

[0014] It can be understood that by setting the first contact surface and / or the first surface to be spherical and the second contact surface and / or the second surface to be spherical, the first adjusting member and the second adjusting member are respectively matched with the spherical surface of the connecting member, while clamping and fixing the connecting member, the connecting member is ensured to have rotational freedom in space, so that the connecting member can adjust its own deflection angle along the spherical surface at a wide angle to adapt to the angular deviation between the reflector and the light source.

[0015] In a possible implementation, the first adjusting member includes a first locking member, and the second adjusting member includes a second locking member. The first locking member is used to press the first surface, and the second locking member is used to press the second surface.

[0016] It can be understood that by providing the first locking member and the second locking member, locking the first surface and the second surface of the connecting member, and clamping and fixing the connecting member in the second direction and the third direction, displacement of the connecting member in the axial direction of the fixed axis is avoided, thereby affecting the positioning accuracy of the reflector and the light source. The second direction and the third direction are located on the same straight line as the axial direction of the fixed axis, and the second direction and the third direction are opposite, the second direction points from the first contact surface to the first surface, and the third direction points from the second contact surface to the second surface.

[0017] In one possible implementation, the first adjusting member further includes a first pressing member, which is located between the first locking member and the connecting member; the first adjusting member further includes a second pressing member, which is located between the second locking member and the connecting member.

[0018] In a possible implementation, the first pressing member is provided with a second through hole, the second pressing member is provided with a third through hole, and the fixed shaft passes through the second through hole, the first through hole, and the third through hole in sequence.

[0019] It can be understood that by providing the second through hole and the third through hole, the assembly and disassembly of the light reflection component are facilitated.

[0020] In a possible implementation manner, there is a gap between the fixed shaft and the inner wall surface of the second through hole, and / or there is a gap between the fixed shaft and the inner wall surface of the third through hole.

[0021] It can be understood that there is a gap between the inner wall surface of at least one of the second through hole and the third through hole and the fixed shaft, which provides a translation space for the fixed shaft along the first direction while pressing the first surface and the second surface of the connecting piece. When the position of the fixed shaft along the first direction changes, the positions of the first pressing piece and the second pressing piece relative to the connecting piece remain unchanged, and the first surface and the second surface are always pressed, thereby ensuring the stability of the connecting piece in the axial direction of the fixed shaft. The first direction is perpendicular to the length direction of the first through hole.

[0022] In a possible implementation manner, a gap between an inner wall surface of the second through hole and / or the third through hole and the fixed shaft is annular.

[0023] It is understandable that by setting the gap between the inner wall surface of the second through hole and / or the third through hole and the fixed shaft to be annular, the fixed shaft has a wide angle adjustment range, which is convenient for adapting the position or angle deviation of the fixed shaft and the reflector.

[0024] In one possible implementation, the fixed shaft is provided with an external thread and / or an internal thread, and the first locking member and / or the second locking member are threadedly connected to the fixed shaft to facilitate the assembly connection between the first locking member and / or the second locking member and the fixed shaft.

[0025] In one possible implementation, one of the first contact surface and the first surface is spherical, and the other is truncated cone-shaped, and / or one of the second contact surface and the second surface is spherical, and the other is truncated cone-shaped.

[0026] It can be understood that the frustum surface is the shape of the outer wall of the frustum. By setting two sets of ball-table fits, the adaptability of the connector in any posture of three rotational degrees of freedom in space is satisfied.

[0027] In a possible implementation manner, the gap between the inner wall surface of the first through hole and the fixed shaft is annular.

[0028] It can be understood that by setting the gap between the inner wall surface of the first through hole and the fixed shaft to be annular, the fixed shaft has a wide angle adjustment range, which is convenient for adapting the position or angle deviation of the fixed shaft and the reflector.

[0029] In one possible implementation, the light reflecting assembly also includes a positioning member, on which a first fixing groove and a second fixing groove are provided, the first fixing groove and the second fixing groove are fixed in relative position, the first fixing groove is used to fix the reflector, and the second fixing groove is used to fix the light source.

[0030] It can be understood that the positioning member is used to perform preliminary positioning of the reflector and the light source to determine the relative position of the reflector and the light source.

[0031] In a possible implementation, the light source includes a body and a terminal, the terminal is connected to the body, and the connecting member includes a clamping mechanism, and the clamping mechanism and the terminal are detachably connected.

[0032] It can be understood that there are one or more terminals, and the clamping mechanism includes a clamping arm, which is used to embrace the terminal to ensure that the relative position of the connector and the light source is fixed, and the clamping arm can be opened or closed to loosen or clamp the terminal.

[0033] In one possible implementation, the clamping mechanism is rotatably connected to the terminal post.

[0034] It is understandable that the clamping arm and the terminal of the light source can rotate relatively around the axis of the terminal to adapt to the processing error of the terminal or the positioning error between the reflector and the light source, thereby ensuring the positioning accuracy of the reflector and the light source.

[0035] In one possible implementation, the connecting member includes a first connecting member and a second connecting member, the first connecting member and the second connecting member are stacked along the axial direction of the fixed axis, the first connecting member and the second connecting member are both provided with the first through hole, and the first connecting member and the second connecting member are respectively connected to the light source.

[0036] It can be understood that the first connecting member has a first surface, and when the adjustment mechanism is locked, the first contact surface contacts the first surface of the first connecting member; the second connecting member has a second surface, and when the adjustment mechanism is locked, the second contact surface contacts the second surface of the second connecting member.

[0037] In a possible implementation, the first connecting member has a third surface, and the second connecting member has a fourth surface in contact with the third surface; the third surface and / or the fourth surface is spherical.

[0038] It can be understood that by setting the third surface and / or the fourth surface to be spherical, the spherical fit of the third surface and the fourth surface is achieved, so that the first connecting member and the second connecting member have three rotational degrees of freedom in space, which is convenient for adjusting their own deflection angle relative to the fixed axis and adapting to the angular deviation between the reflector and the light source.

[0039] In a second aspect, an embodiment of the present application provides a method for using a light reflecting assembly, which is applied to the light reflecting assembly described in the first aspect, and includes: positioning a light source and a reflector; installing a connecting piece and an adjusting mechanism to fix the connecting piece and the light source; adjusting the relative positions of the connecting piece, the adjusting mechanism and the fixed axis to adapt to the relative positions of the light source and the reflector; and fixedly connecting the connecting piece, the adjusting mechanism and the fixed axis to fixedly connect the light source and the reflector.

[0040] In a third aspect, an embodiment of the present application provides a vehicle comprising a light reflecting assembly as described in the first aspect. BRIEF DESCRIPTION OF THE DRAWINGS

[0059] In the description of the embodiments of the present application, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, "connection" can be detachably connected or non-detachably connected; it can be directly connected or indirectly connected through an intermediate medium. Among them, "fixed connection" means that the relative position relationship after connection remains unchanged. The orientation terms mentioned in the embodiments of the present application, such as "top", "bottom", "side", "up", "down", "left" or "right", etc., are only reference directions of the accompanying drawings. Therefore, the orientation terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application. In the following, the terms "first", "second", etc. are used only for descriptive purposes, and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In addition, multiple refers to at least two.

[0060] It should be clear that the embodiments described in this application are only some embodiments, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0061] The terms used in the embodiments of the present application are only for the purpose of describing specific embodiments, and are not intended to limit the present application. The singular forms "a", "said" and "the" used in the embodiments of the present application and the appended claims are also intended to include plural forms, unless the context clearly indicates other meanings.

[0062] It should be understood that the term "and / or" used in this article is only a description of the same field of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0063] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application.

[0064] like Figures 1 to 8 As shown, the light reflection assembly provided in the embodiment of the present application includes: a light source 10, a reflector 20, a fixed axis 30, a connecting member 40 and an adjustment mechanism.

[0065] In the light reflection assembly in the prior art, the light source has a terminal, a clamp is provided to clamp the terminal of the light source, and then the clamp is fixedly connected to the C-shaped part by threaded fasteners, the C-shaped part is connected to the mounting plate by threaded fasteners, and then the mounting plate and the reflector are fixedly connected by threaded fasteners to complete the fixation of the reflector and the light source. Since the clamp and the C-shaped part, the C-shaped part and the mounting plate, and the mounting plate and the reflector are all connected by threaded fasteners, there is a lack of precise positioning structure, which easily leads to angle or position errors between the reflector and the light source, affecting the accuracy and working effect of the light reflection assembly. In addition, the reflector and the light source themselves have certain processing errors and positioning errors. It is difficult to adapt and correct the position error between the reflector and the light source in the prior art, which makes it difficult to ensure the positioning accuracy of the reflector and the light source.

[0066] The light reflection assembly provided in the embodiment of the present application, the fixed shaft 30, the connecting member 40 and the adjusting mechanism connect the light source 10 and the reflector 20 together to achieve connection and position adaptation between the two to meet the working requirements of the actual light reflection system.

[0067] Among them, the light source 10 can be an artificial light source lamp in the shape of a bar, a sphere, a rectangle, etc., and the reflector 20 is used to reflect the light emitted by the reflective light source 10 so that it presents a specific emission form, for example, reflecting the light emitted by the light source 10 as parallel light. Exemplarily, the light reflection component is applied to the automotive field, and the light source 10 can be a headlight, a taillight, a turn signal light, a backlight, an emergency light, a fog light, and other automotive lamps. It can be understood that the light reflection component is not only applicable to the automobiles as described above, but also to any equipment that requires light reflection, and the embodiments of the present application do not strictly limit this.

[0068] The fixed shaft 30 is fixedly connected to the reflector 20. Specifically, the reflector 20 is fixedly connected to the fixed shaft 30 by welding, bonding, fastener connection, etc., so that the relative spatial position of the fixed shaft 30 and the reflector 20 is determined, and the two remain relatively stationary and move synchronously.

[0069] The fixed shaft 30 has an axis extending along its length direction, and the axis can be in a straight line, a curve or other irregular shapes. Preferably, the fixed shaft 30 is a straight line axis. The cross-sectional shape of the fixed shaft 30 along the longitudinal direction is circular, elliptical, rectangular, triangular or any other irregular shape. The above-mentioned "longitudinal direction" is a direction perpendicular to the length direction of the fixed shaft 30.

[0070] The connector 40 is connected to the light source 10. The connector 40 and the light source 10 can be connected by movable connection, detachable connection, fixed connection, etc., so long as the relative spatial position of the connector 40 and the light source 10 is determined when the assembly is completed.

[0071] The connecting member 40 is provided with a first through hole 41, the fixed shaft 30 is passed through the first through hole 41, a gap is provided between the fixed shaft 30 and the inner wall surface of the first through hole 41, and a spherical matching structure is formed between the adjusting mechanism and the connecting member 40. The adjusting mechanism is used to adapt the angle and / or position error of the reflector 20 and the light source 10 when the relative position between the reflector 20 and the light source 10 is determined, so as to ensure the positioning accuracy between the reflector 20 and the light source 10. The adjusting mechanism is connected to the connecting member 40, a spherical matching structure is formed between the adjusting mechanism and the connecting member 40, the adjusting mechanism and the connecting member 40 are in contact, the surface in contact between the adjusting mechanism and the connecting member 40 is spherical, and / or the surface in contact between the connecting member 40 and the adjusting mechanism is spherical.

[0072] The reflector 20 is connected to the fixed shaft 30 , the light source 10 is connected to the connecting member 40 , and the adjusting mechanism adjusts the relative position between the connecting member 40 and the fixed shaft 30 .

[0073] The spherical matching structure allows the fixed shaft 30 and the connecting member 40 to have at least three degrees of rotational freedom along the spherical direction. For example, the connecting member 40 has three degrees of rotational freedom in space, and the connecting member 40 and / or the fixed shaft 30 can rotate within a range of 360° along the spherical surface, which is convenient for adapting to the angle change of the reflector 20 and the light source 10.

[0074] The gap between the fixed shaft 30 and the inner wall surface of the first through hole 41 cooperates with the adjustment mechanism so that the fixed shaft 30 and the connecting member 40 have at least two directions of planar freedom along the direction perpendicular to the axial direction of the fixed shaft 30. Specifically, by setting a gap between the fixed shaft 30 and the inner wall surface of the first through hole 41, a fine-tuning space is formed, so that the fixed shaft 30 can translate in the space surrounded by the first through hole 41 to adjust the relative position of the fixed shaft 30 and the connecting member 40, so that the fixed shaft 30 has two translational degrees of freedom in the first direction, thereby adapting to the position change of the reflector 20 and the light source 10 in the first direction, and ensuring the positioning accuracy of the reflector 20 and the light source 10. Among them, the first direction is perpendicular to the length direction of the first through hole 41, for example Figure 3 As shown, the length direction of the first through hole 41 is the vertical direction, and the first direction is the horizontal direction.

[0075] In a specific embodiment, the gap between the inner wall surface of the first through hole 41 and the fixed shaft 30 is annular. The shape of the gap can be a circular ring, an elliptical ring, a square ring, or a ring of any other shape, as long as the inner contour line and the outer contour line of the gap are closed figures respectively. The gap between the inner wall surface of the first through hole 41 and the fixed shaft 30 is in a continuous ring shape, so that the fixed shaft 30 has a 360° adjustment range, which is convenient for adapting the position or angle deviation of the fixed shaft 30 and the reflector 20.

[0076] The cooperation between the adjusting mechanism and the fixed shaft 30 enables the fixed shaft 30 and the connecting member 40 to have at least one linear degree of freedom along the axial direction of the fixed shaft 30 .

[0077] In a specific embodiment, the adjustment mechanism includes a free state and a locked state. In the free state, the connecting member 40 and the fixed shaft 30 are slidably connected, and the adjustment mechanism is used to move to different positions along the axial direction of the fixed shaft 30 and switch to the locked state. In the free state, the connecting member 40 can move relative to the fixed shaft 30. Specifically, the connecting member 40 can slide along the axial direction of the fixed shaft 30, and the adjustment mechanism can move along the axial direction of the fixed shaft 30 to lock the connecting member 40 in a specific position, so that the position of the connecting member 40 and the fixed shaft 30 is relatively fixed.

[0078] In the locked state, the adjustment mechanism and the fixed shaft 30 are relatively fixed, and the adjustment mechanism and the connecting member 40 are relatively fixed, so that the relative positions of the fixed shaft 30 and the adjustment mechanism remain fixed, and the relative positions of the reflector 20 and the light source 10 remain fixed, thereby achieving locking between the reflector 20 and the light source 10.

[0079] By setting the adjustment mechanism to have a free state and a locked state, the position of the connecting member 40 in the axial direction of the fixed shaft 30 can be adjusted and the connecting member 40 can be locked and fixed, so that the connecting member 40 has a linear degree of freedom in the axial direction of the fixed shaft 30, thereby adapting to the position change of the reflector 20 and the light source 10 in the axial direction of the fixed shaft 30.

[0080] The light reflecting assembly provided in the embodiment of the present application realizes the connection between the reflector 20 and the light source 10 through the connecting member 40 and the fixed axis 30, and adjusts the angle and position relationship between the reflector 20 and the light source 10 through the adjusting mechanism, thereby realizing the adaptation of the reflector 20 and the light source 10 in six degrees of freedom in space, and facilitating the adjustment of the positioning relationship between the reflector 20 and the light source 10.

[0081] For example, if the reflector 20 or the light source 10 has a position deviation in the horizontal direction due to processing errors or positioning errors after assembly, since there is a gap between the first through hole 41 of the connecting member 40 and the fixed axis 30, the relative position and position deviation of the reflector 20 and the light source 10 in the horizontal direction can be adapted and corrected by fine-tuning the horizontal position of the connecting member 40 or the fixed axis 30 to ensure the positioning accuracy of the reflector 20 and the light source 10 in the horizontal direction.

[0082] For example, if the reflector 20 or the light source 10 has an angular deviation in space due to processing errors or positioning errors after assembly, since the adjustment mechanism and the connecting member 40 are spherically connected and there is a gap between the first through hole 41 of the connecting member 40 and the fixed axis 30, the angular deviation of the reflector 20 and the light source 10 in space can be adapted and corrected by adjusting the offset angle of the connecting member 40 or the fixed axis 30.

[0083] For example, if the reflector 20 or the light source 10 has a position deviation in the vertical direction due to processing errors or positioning errors after assembly, since the adjustment mechanism includes a free state and a locked state, the relative position relationship between the connecting member 40 and the fixed axis 30 in the vertical direction can be adjusted in the free state of the adjustment mechanism, and then the adjustment mechanism is switched to the locked state after the adjustment is completed to fix the position of the connecting member 40 and the fixed axis 30, so as to adapt and correct the relative position and position deviation of the reflector 20 and the light source 10 in the vertical direction, thereby ensuring the positioning accuracy of the reflector 20 and the light source 10 in the vertical direction.

[0084] In a further embodiment, the adjustment mechanism includes a first adjustment member and a second adjustment member, which are respectively located on both sides of the connecting member 40 along the axial direction of the first through hole 41 to clamp and fix the connecting member 40 when the adjustment mechanism is in a locked state.

[0085] Exemplarily, the first adjusting member is located on a side of the connecting member 40 relatively far from the light source 10, and the second adjusting member is located on a side of the connecting member 40 relatively close to the light source 10. In the locked state of the adjusting mechanism, the first adjusting member and the second adjusting member are respectively in contact with both sides of the connecting member 40 along the axial direction of the first through hole 41 to clamp and fix the connecting member 40, thereby preventing the connecting member 40 from being displaced and affecting the positioning accuracy between the reflector 20 and the light source 10. Optionally, the first adjusting member may also be located on a side of the connecting member 40 relatively close to the light source 10, and the second adjusting member may be located on a side of the connecting member 40 relatively far from the light source 10, so that the connecting member 40 can be clamped and fixed on both sides of the connecting member 40 along the axial direction of the first through hole 41.

[0086] Exemplarily, the first adjusting member and / or the second adjusting member is installed with an elastic member in the axial direction of the first through hole 41. In a free state, the first adjusting member and / or the second adjusting member can move along the axial direction of the first through hole 41 through the deformation of the elastic member; in a locked state, the first adjusting member and / or the second adjusting member maintains close contact and compression with the connecting member 40 under the action of the elastic member, thereby clamping and fixing the connecting member 40.

[0087] Exemplarily, the first adjusting member and / or the second adjusting member are installed with a locking nut in the axial direction of the first through hole 41. In the free state, the locking nut does not lock the first adjusting member and / or the second adjusting member, and the first adjusting member and / or the second adjusting member can move along the axial direction of the first through hole 41; in the locked state, the locking nut locks the first adjusting member and / or the second adjusting member to limit the movement of the first adjusting member and / or the second adjusting member in the axial direction of the first through hole 41, thereby clamping and fixing the connecting member 40.

[0088] In a further embodiment, the first adjusting member is provided with a first contact surface, the second adjusting member is provided with a second contact surface, the connecting member 40 is provided with a first surface 42 for at least partially contacting the first contact surface, and the connecting member 40 is provided with a second surface 43 for at least partially contacting the second contact surface. The first contact surface and / or the first surface 42 are spherical, and the second contact surface and / or the second surface 43 are spherical.

[0089] Exemplarily, the first adjusting member is located on a side of the connecting member 40 relatively far from the light source 10, and the lower surface of the first adjusting member is the first contact surface; the second adjusting member is located on a side of the connecting member 40 relatively close to the light source 10, and the upper surface of the second adjusting member is the second contact surface. The upper surface of the connecting member 40 is the first surface 42, which is at least partially in contact with the first contact surface; the lower surface of the connecting member 40 is the second surface, which is at least partially in contact with the second contact surface.

[0090] At least one of the first contact surface and the first surface 42 is spherical, so that the first adjusting member and the connecting member 40 form a spherical matching structure. At least one of the second contact surface and the second surface 43 is spherical, so that the second adjusting member and the connecting member 40 form a spherical matching structure. By setting the first adjusting member and the second adjusting member to spherically match the connecting member 40 respectively, while clamping and fixing the connecting member 40, it is ensured that the connecting member 40 has a rotational freedom in space, so that the connecting member 40 can adjust its own deflection angle along the spherical surface at a wide angle to adapt to the angle deviation between the reflector 20 and the light source 10.

[0091] Optionally, one of the first contact surface and the first surface 42 is spherical, and the other is in a plane, an arcuate surface, a truncated cone, a prism, etc. As long as one of the first contact surface and the first surface 42 is spherical, a spherical fitting connection between the first adjusting member and the connecting member 40 can be achieved. The fitting between the second contact surface and the second surface 43 is the same as the above description and will not be repeated here.

[0092] Optionally, the first contact surface and the first surface 42 are both spherical, and the sizes of the first contact surface and the first surface 42 can be matched, or the spherical radius of the first contact surface can be larger than the spherical radius of the first surface 42. It should be noted that the above-mentioned embodiment in which the spherical radius of the first contact surface is larger than the spherical radius of the first surface 42 is applicable to the case where the first contact surface is located above the first surface 42. If the first contact surface is located below the first surface 42, the spherical radius of the first surface 42 is larger than the spherical radius of the first contact surface to avoid limiting the rotation adjustment of the connecting member 40. The coordination between the second contact surface and the second surface 43 is the same as described above and will not be repeated here. For example Figure 3 or Figure 4 As shown, the first contact surface, the first surface 42, the second contact surface, and the second surface 43 are all spherical. By matching the two sets of spherical surfaces, it is ensured that any posture of the connecting member 40 in at least three rotational directions in space can fit with the first contact surface and the second contact surface, thereby satisfying the adaptation of the connecting member 40 in any posture of the three rotational degrees of freedom in space.

[0093] In a specific embodiment, one of the first contact surface and the first surface 42 is spherical, and the other is truncated cone-shaped, and / or one of the second contact surface and the second surface 43 is spherical, and the other is truncated cone-shaped. It can be understood that the truncated cone-shaped is the shape of the outer wall of a truncated cone.

[0094] like Figure 4 As shown, the first surface 42 is spherical, the first contact surface is truncated cone, and a ball-table fit is presented above the connector 40, ensuring that the first surface 42 and the first contact surface can be fitted in any posture of the connector 40 in at least three rotational directions in space. At the same time, the second surface 43 is truncated cone, the second contact surface is spherical, and a ball-table fit is presented below the connector 40, ensuring that the second surface 43 and the second contact surface can be fitted in any posture of the connector 40 in at least three rotational directions in space. In this embodiment, two sets of ball-table fits are used to meet the adaptation of the connector 40 in any posture of three rotational degrees of freedom in space.

[0095] It can be understood that, between the first contact surface and the first surface 42, the one relatively located above is in the shape of a truncated cone, and the one relatively located below is in the shape of a spherical surface; between the second contact surface and the second surface 43, the one relatively located above is in the shape of a truncated cone, and the one relatively located below is in the shape of a spherical surface, so as to ensure that the connecting member 40 can contact and fit with the first contact surface or the second contact surface in any posture in at least three rotation directions in space.

[0096] In a further embodiment, the first adjusting member includes a first locking member 51, and the first adjusting member includes a second locking member 52, the first locking member 51 is used to press the first surface 42 in the locked state, and the second locking member 52 is used to press the second surface 43 in the locked state.

[0097] By providing the first locking member 51 and the second locking member 52, the first surface 42 and the second surface 43 of the connecting member 40 are locked, and the connecting member 40 is clamped and fixed in the second direction and the third direction, so as to prevent the connecting member 40 from being displaced in the axial direction of the fixed shaft 30, thereby affecting the positioning accuracy of the reflector 20 and the light source 10. The second direction and the third direction are located on the same straight line as the axial direction of the fixed shaft 30, and the second direction and the third direction are opposite, the second direction points from the first contact surface to the first surface 42, and the third direction points from the second contact surface to the second surface 43.

[0098] Optionally, the first locking member 51 and the second locking member 52 are locking nuts, and the first locking member 51 and the second locking member 52 are respectively threadedly connected to the fixed shaft 30. By adjusting the height of the first locking member 51 and the second locking member 52 in the axial direction of the fixed shaft 30 in the free state, the relative position of the connecting member 40 and the fixed shaft 30 can be changed. By tightening the first locking member 51 in the second direction and tightening the second locking member 52 in the third direction, the adjustment mechanism is switched to the locked state, the first surface 42 and the second surface 43 are locked, and the connecting member 40 and the fixed shaft 30 remain relatively fixed.

[0099] Optionally, the first locking member 51 and the second locking member 52 are clamping members, and the first locking member 51 and the second locking member 52 are respectively clamped on the fixed shaft 30. The first locking member 51 and the second locking member 52 have a loosened state and a clamped state. In the loosened state, the connecting member 40 can move along the axial direction of the fixed shaft 30, thereby changing the relative position of the connecting member 40 and the fixed shaft 30; in the clamped state, the first locking member 51 and the second locking member 52 are fixed and locked on both sides of the connecting member 40, so that the connecting member 40 and the fixed shaft 30 remain relatively fixed.

[0100] It is understandable that the structures of the first locking member 51 and the second locking member 52 may be the same or different.

[0101] In a further embodiment, the first adjusting member further comprises a first pressing member 53, which is located between the first locking member 51 and the connecting member 40. The first adjusting member further comprises a second pressing member 54, which is located between the second locking member 52 and the connecting member 40.

[0102] Exemplarily, the first pressing member 53 and the second pressing member 54 are elastic members such as springs, and the first pressing member 53 and the second pressing member 54 have elastic deformation capability in the axial direction of the fixed shaft 30. The first surface 42 and the second surface 43 are pressed by the elastic force of the first pressing member 53 and the second pressing member 54.

[0103] Exemplarily, the first pressing member 53 and the second pressing member 54 are rigid pressing blocks, and the first pressing member 53 and the second pressing member 54 have at least two surfaces, one of which is in contact with the connecting member 40, and the other is in contact with the first locking member 51 or the second locking member 52. The first pressing member 53 has a first contact surface, and the first pressing member 53 is in contact with the first surface 42, and is used to press the first surface 42. The first locking member 51 abuts against the surface of the first pressing member 53 away from the first contact surface, thereby locking the first pressing member 53 and locking the first surface 42 along the second direction. The second pressing member 54 has a second contact surface, and the second pressing member 54 is in contact with the second surface 43, and is used to press the second surface 43. The second locking member 52 abuts against the surface of the second pressing member 54 away from the second contact surface, thereby locking the second pressing member 54 and locking the second surface 43 along the third direction.

[0104] In a further embodiment, the first pressing member 53 is provided with a second through hole 530, the second pressing member 54 is provided with a third through hole 540, and the fixing shaft 30 passes through the second through hole 530, the first through hole 41 and the third through hole 540 in sequence. Figure 3 As shown, the first pressing member 53 and the second pressing member 54 are both sleeved on the fixed shaft 30 .

[0105] Optionally, the second pressing member 54 is a split structure and is disposed around the fixed shaft 30 .

[0106] The second through hole 530 and the third through hole 540 are provided to facilitate assembly and disassembly of the light reflection assembly. The inner wall surfaces of the second through hole 530 and the third through hole 540 may be closely fitted with the fixed shaft 30 or may be spaced apart from the fixed shaft 30.

[0107] In a further embodiment, there is a gap between the fixed shaft 30 and the inner wall surface of the second through hole 530 , and / or there is a gap between the fixed shaft 30 and the inner wall surface of the third through hole 540 .

[0108] In this embodiment, there is a gap between the inner wall surface of at least one of the second through hole 530 and the third through hole 540 and the fixed shaft 30, which provides a translational space for the fixed shaft 30 along the first direction while compressing the first surface 42 and the second surface 43 of the connecting member 40. When the position of the fixed shaft 30 along the first direction changes, the positions of the first clamping member 53 and the second clamping member 54 relative to the connecting member 40 remain unchanged, and the first surface 42 and the second surface 43 are always compressed, thereby ensuring the stability of the connecting member 40 in the axial direction of the fixed shaft 30.

[0109] In a further embodiment, the gap between the inner wall surface of the second through hole 530 and / or the third through hole 540 and the fixed shaft 30 is annular.

[0110] In the longitudinal cross-sectional view along the fixed axis 30 , the shape of the gap can be a circular ring, an elliptical ring, a square ring or any other ring shape, as long as the inner contour line and the outer contour line of the gap are closed figures respectively.

[0111] Specifically, the gap between the inner wall surface of the second through hole 530 and / or the third through hole 540 and the fixed shaft 30 is in a continuous ring shape, so that the fixed shaft 30 has a 360° adjustment range, which is convenient for adapting the position or angle deviation of the fixed shaft 30 and the reflector 20.

[0112] Optionally, the gap between the inner wall surface of the second through hole 530 and / or the third through hole 540 and the fixed shaft 30 can also be in a semi-annular shape, so that the fixed shaft 30 has an adjustment range less than 360°, adapting to the position or angle deviation of the fixed shaft 30 and the reflector 20 to a certain extent.

[0113] In a further embodiment, the fixed shaft 30 is provided with an external thread and / or an internal thread, and the first locking member 51 and / or the second locking member 52 are threadedly connected to the fixed shaft 30 to facilitate the assembly connection between the first locking member 51 and / or the second locking member 52 and the fixed shaft 30.

[0114] Exemplarily, the fixed shaft 30 has an external thread, and the first locking member 51 and the second locking member 52 are locking nuts, both of which have internal threads, so that the first locking member 51 and the second locking member 52 are respectively threadedly connected to the fixed shaft 30. By screwing the first locking member 51 and the second locking member 52, the first pressing member 53 and the second pressing member 54 can be loosened or clamped, so that the fixed shaft 30 can be moved along its own axial direction or fixed in position along its own axial direction.

[0115] Exemplarily, the fixed shaft 30 has an internal thread, and the first locking member 51 and the second locking member 52 are locking nuts, both of which have external threads, so that the first locking member 51 and the second locking member 52 are respectively threadedly connected to the fixed shaft 30. It should be noted that, in this embodiment, the first locking member 51 and the second locking member 52 have a threaded portion and a locking portion extending along the axial direction thereof, and the locking portion is located outside the threaded portion. As the threaded connection length of the threaded portion in the fixed shaft 30 changes, the position of the locking portion along the axial direction of the fixed shaft 30 changes accordingly, thereby compressing or loosening the first locking member 51 or the second locking member 52, so that the fixed shaft 30 can move along its own axial direction or be fixed in its own axial direction.

[0116] In a further embodiment, the light reflecting assembly also includes a positioning member 60, on which a first fixing groove 61 and a second fixing groove 62 are provided. The first fixing groove 61 and the second fixing groove 62 are fixed in relative positions. The first fixing groove 61 is used to fix the reflector 20, and the second fixing groove 62 is used to fix the light source 10.

[0117] like Figure 4 As shown, the first fixing groove 61 and the second fixing groove 62 are connected to each other to avoid obstruction of the connection between the reflector 20 and the light source 10. The positioning member 60 is used to preliminarily position the reflector 20 and the light source 10 to determine the relative position of the reflector 20 and the light source 10. Specifically, the reflector 20 and the light source 10 are first fixed to the positioning member 60, and then the adjustment mechanism is installed.

[0118] Furthermore, the positioning member 60 is detachably connected to the reflector 20 and the light source 10. After the adjustment mechanism is installed, the position and angle between the reflector 20 and the light source 10 are adjusted by the adjustment mechanism to ensure the positioning accuracy of the reflector 20 and the light source 10, and then the positioning member 60 can be removed to facilitate the assembly of the light reflection assembly to other devices, equipment or systems.

[0119] In a further embodiment, the connecting member 40 includes a clamping mechanism 46 , and the clamping mechanism 46 and the light source 10 are detachably connected.

[0120] Specifically, the light source 10 includes a body and a terminal 11 , the terminal 11 is connected to the body, and the clamping mechanism 46 and the terminal 11 are detachably connected.

[0121] For example, there are two terminals 11, the main body is in a strip shape, and the two terminals 11 are perpendicular to the main body and spaced apart along the length direction of the main body. The clamping mechanism 46 includes two sets of clamping arms 461, which are used to embrace the terminals 11 to ensure that the relative positions of the connector 40 and the light source 10 are fixed. The clamping arms 461 can be opened or closed to loosen or clamp the terminals 11. Figure 1As shown, the clamping mechanism 46 also includes a fixing nut 462 for fixing the clamping arm 461 so that the clamping arm 461 embraces and clamps the terminal 11. By removing the fixing nut 462, the clamping arm 461 can be moved to facilitate the release of the terminal 11.

[0122] Optionally, the clamping mechanism further includes an adjusting nut 463, which is fixedly connected to the clamping arm 461 and is used to drive the clamping arm 461 to move so as to open or close the clamping arm 461. By setting the adjusting nut 463, it is convenient to manually adjust the state of the clamping arm 461. It is understandable that the number of the terminal 11 is not limited to Figure 2 Two are shown. In other embodiments, the number of the terminals 11 may be one or more, depending on the product requirements.

[0123] By providing a detachable connection between the clamping mechanism 46 and the light source 10, it is not only convenient to install, disassemble or replace the connecting member 40, but also convenient to adapt to light sources 10 of different models or sizes, thereby improving the applicability of the light reflection component.

[0124] In a further embodiment, the clamping mechanism 46 is rotatably connected to the light source 10 .

[0125] Specifically, the clamping arm 461 and the terminal post 11 of the light source 10 can rotate relative to each other around the axis of the terminal post 11 to adapt to the processing error of the terminal post 11 or the positioning error between the reflector 20 and the light source 10, thereby ensuring the positioning accuracy of the reflector 20 and the light source 10.

[0126] An implementation manner of the structure of the connecting member 40 is specifically introduced above in conjunction with the relevant drawings, and another implementation manner of the structure of the connecting member 40 is specifically introduced below in conjunction with the relevant drawings.

[0127] like Figures 5 to 8 As shown, the connecting member 40 includes a first connecting member 410 and a second connecting member 420. Figure 8 As shown, the first connecting member 410 and the second connecting member 420 are stacked along the axial direction of the fixing shaft 30 , and both the first connecting member 410 and the second connecting member 420 are provided with a first through hole 41 , and the first connecting member 410 and the second connecting member 420 are respectively connected to the light source 10 .

[0128] Specifically, Figure 5 or Figure 6 As shown, the first connecting member 410 clamps one terminal 11, the second connecting member 420 clamps another terminal 11, the first connecting member 410 is located above the second connecting member 420, and the fixing shaft 30 is respectively penetrated through the first through hole 41 of the first connecting member 410 and the second connecting member 420.

[0129] The first connecting member 410 has a first surface 42, and when the adjustment mechanism is locked, the first contact surface contacts the first surface 42 of the first connecting member 410; the second connecting member 420 has a second surface 43, and when the adjustment mechanism is locked, the second contact surface contacts the second surface 43 of the second connecting member 420.

[0130] In a further embodiment, the first connecting member 410 has a third surface 44, and the second connecting member 420 has a fourth surface 45 in contact with the third surface 44. The third surface 44 and / or the fourth surface 45 is spherical.

[0131] Specifically, Figure 7 As shown, a side surface of the first connecting member 410 close to the second connecting member 420 is the third surface 44, and the third surface 44 and the first surface 42 are separated from each other; a side surface of the second connecting member 420 close to the first connecting member 410 is the fourth surface 45, and the fourth surface 45 and the second surface 43 are separated from each other. By setting the third surface 44 and / or the fourth surface 45 to be spherical, the spherical fit of the third surface 44 and the fourth surface 45 is achieved, so that the first connecting member 410 and the second connecting member 420 have three rotational degrees of freedom in space, which is convenient for adjusting the deflection angle relative to the axis of the fixed shaft 30, and adapting to the angle deviation between the reflector 20 and the light source 10.

[0132] Furthermore, one of the third surface 44 and the fourth surface 45 is spherical, and the other is conical. The third surface 44 and the fourth surface 45 are spherical-conical, so that the third surface 44 and the fourth surface 45 always keep in contact, and the matching relationship between the two will not be affected by the change in the deflection angle of one.

[0133] It can be understood that the third surface 44 and the fourth surface 45, the one located relatively above is in a frustum shape, and the one located relatively below is in a spherical shape. Figure 7 As shown, the third surface 44 is located above the fourth surface 45, the third surface 44 is in the shape of a truncated cone, the fourth surface 45 is in the shape of a spherical surface, and the first connecting member 410 and the second connecting member 420 are both in the shape of a spherical upper surface and a truncated cone lower surface. The first surface 42 and the first contact surface, the second surface 43 and the second contact surface, and the third surface 44 and the fourth surface 45 are all ball-table matches, and the three sets of ball-table matches can meet the adaptation of the light source 10 and the reflector 20 in any posture of the three rotational degrees of freedom in space.

[0134] In a specific embodiment, the installation process of the light reflection component includes:

[0135] S1: Fix the light source 10 to the first fixing groove 61 of the positioning member 60, and fix the reflector 20 to the second fixing groove 62 of the positioning member 60, so as to complete the initial positioning of the light source 10 and the reflector 20. The fixing shaft 30 and the reflector 20 are fixedly connected.

[0136] S2: Install the second locking member 52 and the second pressing member 54 in sequence;

[0137] S3: The connecting member 40 is arranged above the second pressing member 54 so that the fixing shaft 30 passes through the first through hole 41 ; the clamping mechanism is adjusted to surround the terminal post 11 to achieve the connection between the light source 10 and the connecting member 40 .

[0138] S4: Install the first pressing member 53 and the first locking member 51 above the connecting member 40 .

[0139] After the light reflection assembly is installed, the connector and the adjustment mechanism are adjusted to adapt the relative position between the light source 10 and the reflector 20 in six directions in space to prevent the positioning relationship between the two from changing and affecting the positioning accuracy.

[0140] Furthermore, the disassembly process of the light reflection assembly includes:

[0141] T1: Remove the first locking member 51 and the first pressing member 53 from above the connecting member 40 .

[0142] T2: Adjust the clamping mechanism to loosen the terminal 11 and remove the connecting piece 40 from above the reflector 20.

[0143] T3: Remove the second pressing member 54 and the second locking member 52 from the fixed shaft 30 .

[0144] T4: Take the light source 10 and the reflector 20 out of the positioning member 60 .

[0145] The present application also provides a method for using a light reflection assembly, which is applied to the light reflection assembly provided in any of the above embodiments, and the method includes:

[0146] P1: Initially position the light source 10 and the reflector 20.

[0147] P2: Install the connecting piece 40 and the adjusting mechanism.

[0148] P3: Adjust the connector 40 and the adjustment mechanism of the light reflection assembly to adapt the relative positions of the light source 10 and the reflector 20.

[0149] In one embodiment, step P1 specifically includes: fixing the light source 10 to the first fixing groove 61 of the positioning member 60, fixing the reflector 20 to the second fixing groove 62 of the positioning member 60, and completing the initial positioning of the light source 10 and the reflector 20. The fixing shaft 30 and the reflector 20 are fixedly connected.

[0150] In one embodiment, step P2 specifically includes: installing the second locking member 52 and the second pressing member 54 in sequence; setting the connecting member 40 above the second pressing member 54 so that the fixing shaft 30 passes through the first through hole 41; adjusting the clamping mechanism to embrace the terminal 11 to achieve the connection between the light source 10 and the connecting member 40; and installing the first pressing member 53 and the first locking member 51 above the connecting member 40.

[0151] Step P3 specifically includes: adjusting the connector 40 and the adjusting mechanism along the spherical direction, the direction perpendicular to the axial direction of the fixed axis 30 and the axial direction of the fixed axis 30 respectively, so as to meet the adaptation of the light source 10 and the reflector 20 in any posture in at least six directions in space.

[0152] For example, if the reflector 20 or the light source 10 has a position deviation in a direction perpendicular to the axial direction of the fixed axis 30 due to processing errors or positioning errors after assembly, since there is a gap between the first through hole 41 of the connecting member 40 and the fixed axis 30, the relative position and position deviation of the reflector 20 and the light source 10 in a direction perpendicular to the axial direction of the fixed axis 30 can be adapted and corrected by fine-tuning the horizontal position of the connecting member 40 or the fixed axis 30, thereby ensuring the positioning accuracy of the reflector 20 and the light source 10 in a direction perpendicular to the axial direction of the fixed axis 30.

[0153] For example, if the reflector 20 or the light source 10 has an angular deviation in space due to processing errors or positioning errors after assembly, since the adjustment mechanism and the connecting member 40 are spherically connected and there is a gap between the first through hole 41 of the connecting member 40 and the fixed axis 30, the angular deviation of the reflector 20 and the light source 10 in at least three directions in space can be adapted and corrected by adjusting the offset angle of the connecting member 40 or the fixed axis 30.

[0154] For example, if the reflector 20 or the light source 10 has a position deviation in the axial direction of the fixed axis 30 due to processing errors or positioning errors after assembly, the relative position of the connecting member 40 and the fixed axis 30 in the axial direction of the fixed axis 30 can be adjusted by an adjustment mechanism to adapt and correct the relative position and position deviation of the reflector 20 and the light source 10 in the axial direction of the fixed axis 30, thereby ensuring the positioning accuracy of the reflector 20 and the light source 10 in the vertical direction.

[0155] The embodiment of the present application also provides a vehicle with a light reflection component, including the light reflection component provided by any of the above embodiments. The vehicle can be a car, a train, an electric car, a bicycle, a ship, etc., and the present application does not make specific limitations.

[0156] Specifically, the light source 10 can be a headlight, taillight, turn signal light, backlight, emergency light, fog light or other lamps, and the reflector 20 is used to reflect the light emitted by the light source 10 so that it presents a specific emission form, for example, reflecting the light emitted by the light source 10 into parallel light.

[0157] An embodiment of the present application also provides a device having a light reflecting component, including the light reflecting component provided by any of the above embodiments.

[0158] Exemplarily, the device is any device that has a need for light reflection, such as a solar cell, a photographing device, an illuminator, a laser transmitter, etc. By setting the device to include a light reflection component, not only the working requirements of light reflection are met, but also the positioning error between the light source 10 and the reflector 20 is improved, and the reflection control accuracy of light is improved.

[0159] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application, and should all be included in the protection scope of the present application.
