Description

Technical Field

[0001] This application relates to the field of vehicles, and in particular to a lens assembly for a vehicle and a vehicle. Background Technology

[0002] In related technologies, the lens module of the vehicle headlight adopts a centered positioning method, with the positioning reference of the lens module located in the middle of the corresponding receiving groove. However, due to the possibility of processing errors in the manufactured lens module and receiving groove, a certain positioning gap is reserved to ensure that the lens module can be installed smoothly in the lens module. However, in actual assembly, the centered positioning method will lead to a great uncertainty in the actual assembly position of the lens, resulting in poor consistency of the assembled lens, making it difficult to carry out subsequent mold repair and alignment processes. This will cause errors between the lens and the light source, affecting the light emission effect. Therefore, how to reduce the installation error of the lens assembly has become the technical problem to be solved in this application. Utility Model Content

[0003] This application aims to at least address one of the technical problems existing in the prior art. To this end, one objective of this application is to propose a lens assembly that can reduce lens assembly installation errors.

[0004] This application proposes a vehicle having the aforementioned lens assembly.

[0005] A lens assembly for a vehicle according to an embodiment of this application includes: a mounting housing having a receiving groove formed inside the mounting housing, the inner wall of the receiving groove having a positioning surface and a positioning protrusion disposed opposite to the positioning surface; and a lens body having the lens body received in the receiving groove and the surface of the lens body having a positioning inclined surface formed for cooperating with the positioning protrusion, the positioning inclined surface being inclined toward the corresponding positioning protrusion in a direction close to the positioning surface.

[0006] According to the embodiments of this application, a lens assembly for a vehicle is provided with a positioning slope and a positioning protrusion. When the lens body is installed into the receiving groove, the positioning protrusion contacts the positioning slope. Because the slope is inclined, the force exerted by the positioning protrusion on the positioning slope can be decomposed into vertical and horizontal components. The horizontal component drives the lens body to move towards the positioning surface, so that the lens body is subjected to a force towards the positioning surface, thus achieving a fit with the positioning surface. This avoids the uncertainty of the assembly position caused by gaps, and the actual assembly position of the lens body is more stable, thereby reducing the installation error of the lens assembly.

[0007] According to some embodiments of this application, a lens assembly for a vehicle is provided in a receiving groove, wherein at least two abutment walls facing different directions are provided in the abutment walls, and the positioning protrusions are provided on the abutment walls.

[0008] According to some embodiments of this application, a lens assembly for a vehicle includes a receiving groove having a first wall and a second wall facing each other, a third wall connected to the first wall and the second wall, and a bottom wall connected to the first wall, the second wall and the third wall respectively; wherein the positioning surface is formed on one of the first wall and the second wall, and the positioning protrusion is provided on the bottom wall and the third wall.

[0009] According to some embodiments of the present application, the surface of the positioning protrusion for a vehicle is configured as an arcuate surface.

[0010] According to some embodiments of the present application, in a lens assembly for a vehicle, the positioning protrusion of the third wall gradually decreases in width and / or height in the direction near the bottom wall.

[0011] According to some embodiments of this application, a lens assembly for a vehicle further includes: a pressure plate disposed on the open side of the receiving groove, the pressure plate having a mating protrusion that mates with the lens body, the lens body having a mating inclined surface that abuts against the mating protrusion, the mating inclined surface being inclined toward the corresponding mating protrusion in a direction close to the positioning surface.

[0012] According to some embodiments of this application, in a lens assembly for a vehicle, the surface of the mating protrusion is curved.

[0013] According to some embodiments of this application, a lens assembly for a vehicle has a plurality of limiting surfaces formed on the lens body at intervals in the height direction, and a plurality of limiting protrusions corresponding one-to-one with the plurality of limiting surfaces are provided on the positioning surface of the receiving groove.

[0014] According to some embodiments of this application, in a lens assembly for a vehicle, the cross-sectional area of ​​the receiving groove gradually increases in the opening direction.

[0015] The vehicle according to an embodiment of this application is briefly described below.

[0016] The vehicle according to the embodiments of this application includes the lens assembly of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the lens assembly of any of the above embodiments, the relative position accuracy between the lens body and the light source is significantly improved due to the reduced installation error of the lens assembly. The optical center of the lens body and the light emission center of the light source can maintain a stable correspondence, avoiding the refraction and reflection path offset caused by installation errors. This allows the light emitted by the light source to exit along the preset design path after passing through the lens body. The consistency of optical parameters such as the shape, angle, and illuminance distribution of the light beam is guaranteed, reducing problems such as local overbrightness, underbrightness, or light spot distortion caused by light offset. This improves the light emission quality and reduces the risk of visual misjudgment caused by uneven illumination.

[0033] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0034] The following is for reference. Figures 1-3 A lens assembly 100 for a vehicle according to an embodiment of this application is described.

[0035] According to an embodiment of this application, a lens assembly 100 for a vehicle includes a mounting housing 1 and a lens body 2. The mounting housing 1 has a receiving groove 11 inside. The inner wall of the receiving groove 11 is provided with a positioning surface 111 and a positioning protrusion 112 disposed opposite to the positioning surface 111. The lens body 2 is received in the receiving groove 11, and the surface of the lens body 2 is formed with a positioning inclined surface 21 for cooperating with the positioning protrusion 112. The positioning inclined surface 21 is inclined toward the corresponding positioning protrusion 112 in the direction close to the positioning surface 111.

[0036] In related technologies, the lens module of the vehicle headlight adopts a centered positioning method. The positioning reference of the lens module is located in the middle of the corresponding receiving groove. However, due to the possibility of processing errors in the lens module and receiving groove and other components, a certain positioning gap is reserved to ensure that the lens module can be installed smoothly in the lens module. However, in actual assembly, the centered positioning method will lead to a great uncertainty in the actual assembly position of the lens, resulting in poor consistency of the assembled lens, making it difficult to carry out subsequent mold repair and alignment processes. This will cause errors between the lens and the light source, affecting the light emission effect.

[0037] It is understood that the mounting housing 1 receiving groove 11 of this application is provided with a positioning surface 111 and a positioning protrusion 112 on the opposite side. The lens body 2 is provided with a positioning inclined surface 21 that cooperates with the positioning protrusion 112. The positioning inclined surface 21 is inclined toward the positioning protrusion 112 in the direction close to the positioning surface 111. Specifically, when the lens body 2 is installed into the receiving groove 11, the positioning protrusion 112 contacts the positioning inclined surface 21. Because the positioning inclined surface 21 is inclined, the force exerted by the positioning protrusion 112 on the positioning inclined surface 21 can be decomposed into a component force perpendicular to the inclined surface and a component force along the positioning inclined surface 21. The component force along the positioning inclined surface 21 will cause the lens body 2 to be subjected to a force toward the positioning surface 111 and drive the lens body 2 to move toward the positioning surface 111.

[0038] Under the action of the component force along the positioning inclined surface 21, the lens body 2 will gradually move towards the positioning surface 111 and eventually fit into the positioning surface 111. At this time, the position of the lens body 2 in the receiving groove 11 no longer changes arbitrarily due to the positioning gap, but is determined by the positioning surface 111 as a reference. This avoids the problem of uncertainty in the assembly position caused by the original centering positioning and gap. The actual assembly position of the lens body 2 is more stable and uniform, thereby reducing the installation error of the lens assembly 100.

[0039] According to some embodiments of this application, a lens assembly 100 for a vehicle has at least two abutment walls 12 facing different directions in a receiving groove 11, and positioning protrusions 112 are provided on the abutment walls 12.

[0040] Setting at least two abutment walls 12 with different orientations means that the force exerted by the positioning protrusions 112 on the lens body 2 toward the positioning surface 111 comes from different directions. The forces from different directions act together on the lens body 2, forming a multi-directional constraint. Under the action of the multi-directional force, as the lens body 2 moves toward the positioning surface 111, the displacement of the lens body 2 in the receiving groove 11 is restricted to a specific dimension, avoiding the swaying or rotation that may occur when only a single direction of force is applied.

[0041] Specifically, the positioning protrusions 112 on the abutment walls 12 with different orientations cooperate with the corresponding positioning inclined surfaces 21, so that the lens body 2 is subjected to component forces pointing towards the positioning surface 111 in multiple directions. These component forces work together to counteract the lateral offset tendency of the lens body 2 that may occur due to processing errors or assembly. It can be understood that if one abutment wall 12 is set along the X-axis direction and the other along the Y-axis direction, then the lens body 2 will be subjected to forces towards the positioning surface 111 in both the X-axis and Y-axis directions, thereby ensuring that the lens body 2 can stably approach and eventually fit towards the positioning surface 111 in both directions. This further reduces the fluctuation range of the assembly position of the lens body 2, improves the consistency of the relative position of the lens body 2 and the light source, and thus more effectively reduces installation errors and ensures the stability of the light emission effect.

[0042] According to some embodiments of this application, a lens assembly 100 for a vehicle has a receiving groove 11 in which a first wall 13 and a second wall 14 facing each other, a third wall 15 connected to the first wall 13 and the second wall 14, and a bottom wall 16 connected to the first wall 13, the second wall 14 and the third wall 15 respectively; wherein a positioning surface 111 is formed on one of the first wall 13 and the second wall 14, and a positioning protrusion 112 is provided on the bottom wall 16 and the third wall 15.

[0043] Understandably, when the lens body 2 is inserted into the receiving groove 11, the positioning protrusion 112 on the bottom wall 16 will contact the positioning inclined surface 21 corresponding to the bottom of the lens body 2, and the positioning protrusion 112 on the third wall 15 will contact the positioning inclined surface 21 corresponding to the side of the lens body 2. Due to the inclined characteristics of the positioning inclined surface 21, the force exerted by the positioning protrusion 112 on the positioning inclined surface 21 it contacts can be decomposed into a normal component perpendicular to the positioning inclined surface 21 and a tangential component along the inclined surface pointing towards the positioning surface 111. This tangential component will drive the lens body 2 to move towards the positioning surface 111. Similarly, the force exerted by the positioning protrusion 112 on the positioning inclined surface 21 it contacts will also be decomposed into a tangential component along the inclined surface pointing towards the positioning surface 111, further pushing the lens body 2 towards the positioning surface 111.

[0044] Meanwhile, the first wall 13 and the second wall 14 face each other, providing an installation boundary for the lens body 2 in this direction and preventing excessive offset of the lens body 2 in this direction. The bottom wall 16, as a structure connecting with the first wall 13, the second wall 14, and the third wall 15, has positioning protrusions 112 on its side and the third wall 15 on its side, respectively, applying forces pointing towards the positioning surface 111 to the lens body 2 from different directions, forming a multi-directional driving force. Under the combined action, the lens body 2 will not only move towards the positioning surface 111, but also, under the constraint of the bottom wall 16 and the third wall 15, avoid unnecessary displacement in other non-target directions. When the lens body 2 is finally aligned with the positioning surface 111, its position within the receiving groove 11 is determined with the positioning surface 111 as the reference. The positioning protrusions 112 on the bottom wall 16 and the third wall 15 apply forces to the lens body 2 from different directions, pointing towards the positioning surface 111. Combined with the boundary constraints of the first wall 13 and the second wall 14, the assembly position of the lens body 2 becomes more stable and unique, significantly reducing the installation error caused by positioning gaps and processing errors, improving the consistency of the lens body 2 assembly, and thus facilitating the smooth progress of subsequent mold repair and alignment processes. This ensures the relative positional accuracy between the lens body 2 and the light source, and can improve the light emission effect.

[0045] According to some embodiments of this application, the lens assembly 100 for a vehicle has a positioning protrusion 112 with a surface configuration of an arcuate surface 113.

[0046] The arc-shaped surface 113 of the positioning protrusion 112 contacts the positioning inclined surface 21 of the lens body 2. The contact between the arc-shaped surface 113 and the positioning inclined surface 21 is either a point contact or a line contact, depending on the curvature of the arc-shaped surface 113 and their relative positions. The separate contact form between the arc-shaped surface 113 and the positioning inclined surface 21 makes the stress distribution in the contact area more concentrated, and when the lens body 2 is displaced by a force toward the positioning surface 111, the relative sliding between the arc-shaped surface 113 and the positioning inclined surface 21 is smoother and the frictional resistance is smaller.

[0047] Due to manufacturing errors in the components, there may be slight deviations in size and shape between the positioning inclined surface 21 of the lens body 2 and the positioning protrusion 112 of the mounting housing 1. If the positioning protrusion 112 is flat, the contact between the flat surface and the positioning inclined surface 21 may experience local interference or poor contact due to the deviation, resulting in unstable force applied to the lens body 2 or deviation from the preset direction. However, the curved surface 113 has curvature, and during the contact process, the position of the contact point with the positioning inclined surface 21 can be adjusted through the adaptability of the curved surface, compensating for the slight deviations caused by manufacturing errors, ensuring that the direction of the force exerted by the positioning protrusion 112 on the positioning inclined surface 21 is always along the tangent of the positioning inclined surface 21, and ensuring the stability and accuracy of the driving force.

[0048] According to some embodiments of the present application, in a lens assembly 100 for a vehicle, the positioning protrusion 112 of the third wall 15 gradually decreases in width and / or height in the direction near the bottom wall 16.

[0049] When the lens body 2 is inserted into the receiving groove 11, it must first contact the positioning protrusion 112 of the third wall 15 and move relative to it to its final position. Since the width and / or height of the positioning protrusion 112 gradually decreases in the direction near the bottom wall 16, its initial contact area with the positioning inclined surface 21 of the lens body 2 is small. In the early stage of assembly, the contact point between the lens body 2 and the positioning protrusion 112 is located at the upper part of the larger protrusion. At this time, the force generated by the contact is mainly used to guide the lens body 2 to move towards the bottom wall 16. Moreover, due to the small contact area, the frictional resistance is small, which facilitates the smooth entry of the lens body 2 into the receiving groove 11, reduces jamming during the assembly process, and reduces the assembly difficulty.

[0050] According to some embodiments of this application, the lens assembly 100 for a vehicle further includes a pressure plate 3, which is disposed on the open side 17 of the receiving groove 11. The pressure plate 3 is provided with a mating protrusion 31 that mates with the lens body 2. The lens body 2 is provided with a mating inclined surface 22 that abuts against the mating protrusion 31. The mating inclined surface 22 is inclined toward the corresponding mating protrusion 31 in the direction close to the positioning surface 111.

[0051] After the lens body 2 is received in the receiving groove 11, the pressure plate 3 is set on the open side 17 of the receiving groove 11. At this time, the mating protrusion 31 on the pressure plate 3 contacts the mating inclined surface 22 of the lens body 2. Since the mating inclined surface 22 is inclined towards the corresponding mating protrusion 31 in the direction close to the positioning surface 111, the force exerted by the mating protrusion 31 on the mating inclined surface 22 can be decomposed into a normal component perpendicular to the mating inclined surface 22 and a tangential component along the direction of the mating inclined surface 22 pointing towards the positioning surface 111. The tangential component will drive the lens body 2 to continue towards the positioning surface. The movement in direction 111 works in conjunction with the force applied by the positioning protrusion 112 in the receiving groove 11. The positioning protrusion 112 in the receiving groove 11 applies a force toward the positioning surface 111 from below or the side, while the mating protrusion 31 of the pressure plate 3 applies a force toward the positioning surface 111 from the open side 17. The multi-directional force can counteract the lateral offset tendency that may occur in the lens body 2 during assembly, avoid the lens body 2 from tilting due to uneven force in a single direction, and ensure that the lens body 2 fits the positioning surface 111 more tightly and stably.

[0052] Meanwhile, the setting of the pressure plate 3 can also limit the displacement of the lens body 2 in the direction of the open side 17 of the receiving groove 11. During the vehicle's operation, the lens body 2 may undergo slight displacement due to vibration. The continuous contact between the mating protrusion 31 and the mating inclined surface 22 can, through the above-mentioned force component mechanism, promptly pull the lens body 2 back to the position of the mating positioning surface 111, maintain the stability of its assembly position, and reduce the recurrence of installation errors caused by vibration.

[0053] According to some embodiments of this application, a lens assembly 100 for a vehicle has a surface configuration of a protrusion 31 as an arc surface 311.

[0054] During the process of the lens body 2 moving towards the positioning surface 111 under the driving force, the relative sliding between the arc surface 311 and the mating inclined surface 22 is smoother. The rounded transition of the arc surface 311 reduces the frictional resistance during sliding, avoids the jamming phenomenon that may occur in the plane contact, and enables the lens body 2 to move smoothly towards the positioning surface 111, reducing the positional deviation caused by poor sliding and ensuring that the lens body 2 can reliably fit the positioning surface 111.

[0055] According to some embodiments of this application, a lens assembly 100 for a vehicle has a lens body 2 having a plurality of limiting surfaces 23 spaced apart in the height direction, and a plurality of limiting protrusions 18 corresponding one-to-one with the plurality of limiting surfaces 23 are provided on the positioning surface 111 of the receiving groove 11.

[0056] When the lens body 2 moves toward the positioning surface 111 under the action of multi-directional force, multiple limiting protrusions 18 will contact the corresponding limiting surfaces 23. Since the limiting surfaces 23 are spaced apart in the height direction and the limiting protrusions 18 correspond one-to-one, the contact points between the limiting protrusions 18 and the limiting surfaces 23 form multiple constraint points in the height direction. The multiple constraint points together constitute multi-point positioning of the lens body 2 in the direction of the positioning surface 111. Compared with single-point positioning, it can more comprehensively restrict the attitude of the lens body 2.

[0057] Specifically, if only a single limiting surface 23 engages with the limiting protrusion 18, the lens body 2 may experience slight rotation or tilting around that contact point, resulting in insufficient fit with the positioning surface 111 and the existence of local gaps. However, when multiple spaced limiting surfaces 23 engage with the limiting protrusion 18, each contact point constrains the local position of the lens body 2, and the interaction between adjacent contact points can counteract the rotational tendency of the lens body 2. For example, the upper limiting protrusion 18 contacting the limiting surface 23 can limit the upper displacement of the lens body 2, while the lower one limits the lower displacement. The combination of both ensures that the lens body 2 as a whole is parallel and fitted to the positioning surface 111, avoiding local positional deviations caused by tilting.

[0058] According to some embodiments of this application, in a lens assembly 100 for a vehicle, the receiving groove 11 has a gradually increasing cross-sectional area in the opening direction.

[0059] When the lens body 2 is inserted into the receiving slot 11, it needs to enter from the open side 17 and move inward. Since the cross-sectional area of ​​the receiving slot 11 gradually increases along the opening direction, the entrance size of its open side 17 is relatively larger, providing more space for the initial insertion of the lens body 2. Even if there are slight dimensional deviations in the lens body 2 or the receiving slot 11 due to processing, the larger entrance can reduce the risk of interference during initial contact, reduce jamming caused by alignment difficulties in the early stages of assembly, and make it easier for the lens body 2 to enter the receiving slot 11, reducing the difficulty of assembly operations. At the same time, the gradually increasing cross-sectional area can compensate for assembly deviations caused by processing errors. When there are slight dimensional deviations in the lens body 2, the large cross-sectional area of ​​the open side 17 can accommodate these deviations, while the gradually narrowing internal structure can still guide the lens body 2 to the correct position through a guiding action, ensuring that the lens body 2 can ultimately reliably fit with the positioning surface 111, further reducing installation errors caused by instability in the assembly process and improving the assembly consistency of the lens assembly 100.

[0061] The vehicle according to the embodiments of this application includes the lens assembly 100 of any of the above embodiments. Since the vehicle according to this embodiment is equipped with the lens assembly 100 of any of the above embodiments, the vehicle according to this application has a reduced installation error of the lens assembly 100, and the relative position accuracy between the lens body 2 and the light source is significantly improved. The optical center of the lens body 2 and the light emission center of the light source can maintain a stable correspondence, avoiding the refraction and reflection path offset caused by installation error. This allows the light emitted by the light source to exit according to the preset design path after passing through the lens body 2. The consistency of optical parameters such as the shape, angle, and illuminance distribution of the light beam is guaranteed, reducing problems such as local overbrightness, underbrightness, or light spot distortion caused by light offset, improving the light emission quality, and reducing the risk of visual misjudgment caused by uneven illumination.
