[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0027] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections, electrical connections, or mutual communication; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or the interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0028] The following will describe in detail the method for calculating the assembly spacing between the vehicle lamp module and adjacent light-emitting modules in the present application with reference to the accompanying drawings and specific embodiments.

[0029] In the prior art, when a combination of multiple printed circuit boards is used to meet the lighting requirements of a large area of ​​a vehicle lamp, light sources between adjacent printed circuit boards are easily misaligned when observed at a close distance, resulting in poor visual effects.

[0030] To solve the above technical problems, the embodiment of the present application provides a vehicle lamp module, which comprises a support and a printed circuit board, the printed circuit board is fixed on the support through a fixing structure, and a light emitting unit is arranged on the surface of the printed circuit board away from the support; wherein the printed circuit board is at least provided with two, the two outer edges of the two adjacent printed circuit boards close to each other are a first edge and a second edge, the maximum distance between the first edge and the second edge is h1 mm, the maximum distance from the light emitting unit close to the second edge on the printed circuit board where the first edge is located to the first edge is h2 mm, and the maximum distance from the light emitting unit close to the first edge on the printed circuit board where the second edge is located to the second edge is h3 mm, and the following is met: 0.1≤h1+h2+h3<D, wherein D is the minimum size that can be distinguished by the human eye when a preset following distance condition is met, 0.67≤D≤1.16, and the unit is mm.

[0031] By controlling the distance between the first edge and the second edge, the distance from the light emitting unit to the first edge, and the distance from the light emitting unit to the second edge, the adjacent two printed circuit boards will not produce obvious misalignment, and the overall visual effect of the vehicle lamp is improved, and the light source misalignment will not be observed when following the vehicle at a close distance. The following is described in detail.

[0032] Referring to Figure 1 and Figure 3-5 In an embodiment, the vehicle lamp module comprises a support 10 and a printed circuit board 20, the printed circuit board 20 is fixedly arranged on the support 10 through a fixing structure 30, and a light emitting unit 21 is arranged on the surface of the printed circuit board 20 away from the support 10, the light emitting unit 21 is used to provide a light source; the printed circuit board 20 is at least provided with two, the number of the printed circuit board 20 is not limited in the embodiment, and the modeling requirement of the vehicle lamp can be met; the two outer edges of the two adjacent printed circuit boards 20 close to each other are a first edge 22 and a second edge 23, the maximum distance between the first edge 22 and the second edge 23 is h1 mm, the maximum distance from the light emitting unit 21 close to the second edge 23 on the printed circuit board 20 where the first edge 22 is located to the first edge 22 is h2 mm, and the maximum distance from the light emitting unit 21 close to the first edge 22 on the printed circuit board 20 where the second edge 23 is located to the second edge 23 is h3 mm, and the following is met: 0.1≤h1+h2+h3<D, wherein D is the minimum size that can be distinguished by the human eye when a preset distance condition is met, 0.67mm≤D≤1.16mm.

[0033] It should be noted that the maximum distance between the first edge 22 and the second edge 23 is h1 mm, in the embodiment, the first edge 22 and the second edge 23 are parallel, the distance between the two is h1 mm from top to bottom Figure 5The maximum distance is the constant value. In some embodiments, the first edge 22 is not parallel to the second edge 23, and the value of h1 is the maximum distance between the first edge 22 and the second edge 23. The maximum distance will not cause the light source to be misaligned, and the remaining places will not cause the light source to be misaligned. In addition, the maximum distance from the light-emitting unit 21 close to the second edge 23 on the printed circuit board 20 to the first edge 22 is h2 mm. In this embodiment, the edge of the light-emitting unit 21 close to the first edge 22 is parallel to the first edge 22, that is, the distance between the two is equal from top to bottom, and the maximum distance is the constant value. In some embodiments, the edge of the light-emitting unit 21 close to the first edge 22 is not parallel to the first edge 22, and the value of h2 is the maximum distance between the two. The maximum distance will not cause the light source to be misaligned, and the remaining places will not cause the light source to be misaligned. Similarly, the value of h3 is also the same, which will not be described here.

[0034] D is the minimum size that can be distinguished (seen) by the human eye when the preset distance (the distance between the human eye and the object being observed) is met, and the unit is mm. The value of D is different at different preset distances. In this embodiment, the preset distance is the distance from the driver of the rear vehicle to the tail light of the front vehicle. For example, when the preset distance is X1, the minimum size of the object that can be distinguished by the human eye is D1. When the preset distance is X2 (X2 is limited to be greater than X1 here), that is, the distance from the driver of the rear vehicle to the tail light of the front vehicle increases, the minimum size of the object that can be distinguished by the human eye increases from D1 to D2. Because when the preset distance is X1, the minimum size of the object that can be distinguished by the human eye is D1, the object with a size of D1 is moved away from the driver of the rear vehicle (that is, the preset distance increases), and the human eye cannot see the object with a size of D1 after the preset distance increases. In order for the human eye to see the object after the preset distance increases, the size of the object with a size of D1 needs to be increased, that is, when the preset distance increases, the minimum size that can be seen by the human eye will also increase accordingly.

[0035] In this embodiment, D = 10 3 *2*(d1+d2)*tan(θ / 2), wherein d1 is the following distance between the rear vehicle and the front vehicle, with the unit m, satisfying: 0.3≤d1≤1; d2 is the distance from the driver of the rear vehicle to the front of the rear vehicle, with the unit m, satisfying: 2≤d2≤3; θ is the resolution of the visual angle of the human eye, with the unit rad (radian unit), satisfying: θ = 2.91*10 -4 ; d1+d2 is the preset distance, and the calculation result is 0.67≤D≤1.16.

[0036] When the value of h1+h2+h3 is less than 0.1, i.e. the distance between the two adjacent light units 21 (two light units 21 on two adjacent printed circuit boards 20, the same below) is too small, when the printed circuit board 20 is installed, the two adjacent light units 21 are easy to collide, which reduces the service life and yield of the vehicle lamp;

[0037] Regarding the D value of the present application, taking the case that the preset following distance reference d1+d2 is 2.3 m as an example: when d1+d2 is 2.3 m, the calculated value of D is 0.67 mm, and when the value of h1+h2+h3 is designed to be less than 0.67 mm, the light source between the adjacent printed circuit boards 20 will not be observed to be misaligned, which improves the overall visual effect of the vehicle lamp.

[0038] Further, as a preferred, in an embodiment, 0.1≤h1+h2+h3≤0.5, at this time, the distance between the adjacent light units 21 is in a smaller range, the visual effect is better, and the misalignment will not be observed in closer following (less than 2.3 m). This is because, when the value of h1+h2+h3 is greater than 0.5 and less than 0.67, under the condition of the preset normal following distance of 2.3 m, although it does not affect the observation of the rear driver to the front tail lamp, it can also ensure that the light source will not be obviously misaligned, however, due to the distance between the two adjacent light units 21 is larger than 0.5, in the case of closer following driving or extremely close observation (such as less than 2.3 m), the light source between the adjacent printed circuit boards 20 may be observed to be misaligned, that is, when 0.5

[0039] It should be noted that, Figure 4 In the visual angle, in the longitudinal column of the plurality of light units 21 on the printed circuit board 20 close to the first edge 22 (or the second edge 23) of the first edge 22, each individual light unit 21 satisfies 0.1≤h1+h2+h3≤0.5; similarly, in the longitudinal column of the plurality of light units 21 on the printed circuit board 20 close to the second edge 23 (or the first edge 22) of the second edge 23, each individual light unit 21 satisfies 0.1≤h1+h2+h3≤0.5.

[0040] In an embodiment, the values of h2 and h3 can both be 0.2, which can ensure that the adjacent two light emitting units 21 are not prone to damage during installation, improve the yield and service life, and also will not make the spacing between the two light emitting units 21 too large to have a significant sense of misplacement; at this time, the value of h1 can be no more than 0.1, and the spacing between the adjacent two printed circuit boards 20 can be 0.1 mm, which provides some installation allowance for the installation of the two printed circuit boards 20, protects the adjacent two light emitting units 21 (avoids collision) while also facilitating the installation of the printed circuit board 20 on the fixing structure 30; the adjacent two printed circuit boards 20 can also be in close contact with each other (h1 value is 0), and the adjacent printed circuit boards 20 will support each other, improving the overall stability and thus improving the visual effect of the light. In some embodiments, h2 and h3 can also take other values, which are determined according to actual installation process and other needs, and are not limited thereto.

[0041] In an embodiment, each printed circuit board 20 is arranged on the same bracket 10, i.e., a plurality of printed circuit boards 20 are fixed on one bracket 10, and the large-area lighting demand is completed on one bracket 10. Such an arrangement does not exist in the state of indirect positioning, and the positioning of the plurality of printed circuit boards 20 is completed by a single bracket 10, which reduces the deviation between the adjacent two light emitting units 21 on the adjacent two printed circuit boards 20, reduces the misplacement of the light source, and effectively improves the visual effect of the vehicle lamp.

[0042] Referring to Figure 1 and Figure 6 In an embodiment, the fixing structure 30 includes a positioning column 31, a mounting column 32, a connecting through hole 33, and a connecting screw, the end face of the mounting column 32 toward the printed circuit board 20 has a threaded hole 321, the connecting through hole 33 is arranged at least at the four corners of the printed circuit board 20, and the positioning column 31 and the mounting column 32 are arranged on the bracket 10; the positioning column 31 is inserted into at least two connecting through holes 33 to preliminarily position the printed circuit board 20, and the connecting screw is connected with the threaded hole 321 after passing through the remaining connecting through hole 33 to fix the printed circuit board 20 on the end face of the mounting column 32.

[0043] During the installation process of the printed circuit board 20, some of the connecting through-holes 33 on the printed circuit board 20 are aligned with the positioning posts 31 on the bracket 10. The positioning posts 31 are inserted into the connecting through-holes 33 until the surface of the printed circuit board 20 facing the bracket 10 contacts the end surface of the mounting posts 32 (the surface facing the printed circuit board 20). The printed circuit board 20 is then installed in place. Finally, connecting screws are passed through the connecting through-holes 33 and tightened into the threaded holes 321 to secure the printed circuit board 20. During installation, the printed circuit board 20 is pre-positioned by at least two positioning posts 31, ensuring the stability of the printed circuit board 20 while also positioning the connecting through-holes 33 not connected to the positioning posts 31 with the threaded holes 321 on the mounting posts 32. This results in a simple structure and ease of use.

[0044] It should be noted that positioning the printed circuit board 20 at the four corners can ensure the stability of the printed circuit board 20. In some embodiments, when a single printed circuit board 20 is long or wide, connecting holes 33 can be added between the four corners to strengthen the fixation of the printed circuit board 20. In this embodiment, the height of the mounting post 32 ( Figure 1 The horizontal dimension of the mounting post 32 is set to adjust the surfaces of the two adjacent printed circuit boards 20 provided with the light emitting units 21 to be flush, thereby avoiding the horizontal dimension between the two adjacent printed circuit boards 20 ( Figure 1 The deviation in viewing angle) effectively improves the visual effect of the headlights.

[0045] In some embodiments, four connecting through holes 33 are provided, one at each corner of the printed circuit board 20. Two connecting through holes 33 at one diagonal position are connected to the positioning post 31, while the other two connecting through holes 33 are secured by screws. This diagonal arrangement further improves the positioning of the printed circuit boards 20 and prevents misalignment between adjacent printed circuit boards 20.

[0046] In some embodiments, one of the two diagonally arranged connecting through holes 33 connected to the positioning post 31 is in an elongated strip shape, which can facilitate the installation of the printed circuit board 20. The connection operation between the positioning post 31 and the connecting through hole 33 improves assembly efficiency.

[0047] In some embodiments, other connecting through holes 33 are provided diagonally near the connecting through holes 33 for connecting to the positioning posts 31, and corresponding mounting posts 32 are provided on the brackets 10 opposite these connecting through holes 33, which are connected to the threaded holes 321 on the mounting posts 32 by connecting screws to further fix the printed circuit board 20.

[0048] See Figure 2In an embodiment, the maximum distance between the hole wall of the connecting through hole 33 and the column surface of the positioning column 31 opposite to the hole wall is d mm, satisfying: 0≤d≤0.1, for example, 0, 0.1, etc.; when d is 0-0.1, the positioning column 31 is inserted into the connecting through hole 33, which can ensure the stability of the printed circuit board 20; when the value of d is greater than 0.1, the distance between the hole wall of the connecting through hole 33 and the column surface of the positioning column 31 opposite to the hole wall is too large, which is not conducive to the positioning of the printed circuit board 20, and is easy to cause the misalignment of the light source between the adjacent two printed circuit boards 20, thereby reducing the visual effect of the vehicle lamp.

[0049] It should be noted that when the connecting through hole 33 connected with the positioning column 31 is long strip-shaped, the positioning column 31 is limited by the inner wall with longer length of the connecting through hole 33, and the distance d is the distance between the inner wall with longer length of the connecting through hole 33 and the positioning column 31.

[0050] In an embodiment, the surface of each printed circuit board 20 provided with the light emitting unit 21 is located on the same plane or curved surface, that is, the surfaces of each printed circuit board 20 provided with the light emitting unit 21 are connected to form a smooth surface, which can reduce the misalignment of the light source between the adjacent printed circuit boards 20, and the specific shape of the surface is determined according to the actual vehicle lamp modeling requirements.

[0051] On the other hand, the present application also relates to a vehicle lamp, comprising any one of the foregoing vehicle lamp modules.

[0052] On the other hand, the present application also relates to a vehicle, comprising the foregoing vehicle.

[0053] On the other hand, the present application also relates to a method for calculating the assembly distance of adjacent light emitting modules, comprising the following steps: determining the following distance between a rear vehicle and a front vehicle as d1 m (m is the unit of length, the same below), satisfying: 0.3≤d1≤1; determining the distance from the driver of the rear vehicle to the front of the rear vehicle as d2 m, satisfying: 2≤d2≤3; determining the visual resolution of the human eye as θ rad, satisfying: θ=2.91*10 -4 ; calculating the minimum size D mm that can be distinguished by the human eye when satisfying the preset following distance condition (d1+d2), satisfying:

[0054] D=10 3 *2*(d1+d2)*tan(θ / 2), and it is calculated that: 0.67≤D≤1.16; finally, determining the assembly distance H mm of the adjacent light emitting modules, satisfying: 0.1≤H<D.

[0055] It should be noted that the following distance between the rear vehicle and the front vehicle includes the following distance in the driving state and the following distance in the parking state (for example, the following distance when waiting for a red light), and the following distance is d1m, which satisfies: 0.3≤d1≤1, for example, 0.3, 0.5, 0.8, 1, etc. When the value of d1 is less than 0.3, the following distance is extremely close, which does not meet the conventional driving condition, and when the value of d1 is greater than 1, the following distance is far enough, and it is not easy to see the misalignment of the tail light source of the front vehicle, so 0.3≤d1≤1 is selected.

[0056] The distance from the rear vehicle driver to the front of the rear vehicle is d2m, which satisfies: 2≤d2≤3, for example, 2, 2.5, 3, etc. The distance from the driver's position to the front of the vehicle may vary between different vehicle models and designs, and the exact value of this distance may be affected by factors such as vehicle type, body length, front windshield inclination, etc. The present application selects a more appropriate range.

[0057] The angular resolution of the human eye is θrad (radian units), and the angular resolution of the human eye is usually measured in terms of angle (in degrees). Generally speaking, the angular resolution of the human eye is about 1 arcminute, i.e. 1 / 60 degrees (i.e. 2.91*10 - 4 This means that the human eye can distinguish the angular difference between adjacent objects by about 1 arcminute.

[0058] At different preset distances, the minimum size Dmm that the human eye can distinguish is different, which satisfies the condition: D=10 3 *2*(d1+d2)*tan(θ / 2); through the calculation of the above d1 and d2, 0.67≤D≤1.16; when the rear vehicle follows the front vehicle, the distance from the rear vehicle driver to the tail light of the front vehicle is d1+d2, and at this preset distance (d1+d2), the minimum object size that the human eye can distinguish is D.

[0059] The assembly distance of the adjacent light emitting modules of the front vehicle is Hmm, which satisfies: 0.1≤H<D; that is, when the assembly distance of the adjacent light emitting modules of the front vehicle is less than D, the misalignment of the tail light of the front vehicle will not be seen when the rear vehicle follows, which improves the visual effect.

[0060] In one embodiment, d1=0.3, d2=2, and D=0.67. When the values of d1 and d2 are the smallest (i.e., the closest following vehicle and the most stringent case are selected as the calculation basis), the minimum size that can be distinguished by the human eye is 0.67; that is, the assembly spacing of the adjacent light emitting modules of the tail light of the preceding vehicle is less than 0.67. Under the size limitation, it is difficult to see the misalignment of the tail light of the preceding vehicle when following the vehicle at a normal distance (the distance between the driver and the preceding vehicle is greater than or equal to 2.3 m). In addition, if the values of d1 and d2 are selected to be larger, i.e., a larger and more relaxed following distance is selected as the calculation basis, the value of D is also increased (greater than 0.67). At this time, it also needs to satisfy: 0.1≤H<D.

[0061] It should be noted that the adjacent light emitting modules in the above embodiments are the spacing between the light emitting units 21 mounted on different printed circuit boards 20 and adjacent to each other; that is, H=h1+h2+h3.

[0062] By using the technical solutions provided in the embodiments of the present application, the spacing between the first edge and the second edge, the spacing of the light emitting unit to the first edge, and the spacing of the light emitting unit to the second edge are controlled, so that no obvious misalignment is generated when viewing the adjacent two printed circuit boards, the overall visual effect of the vehicle lamp is improved, and the light source misalignment cannot be observed when following the vehicle at a close distance.

[0063] In the various embodiments of the present application, the terms or descriptions of different embodiments are consistent and can be mutually referenced if there is no special description and logical conflict. The technical features in different embodiments can be combined to form new embodiments according to their inherent logical relationship. In the present application, "at least one" means one or more, and "multiple" means two or more.

[0064] It can be understood that the various numbers involved in the embodiments of the present application are only for convenient differentiation, and do not limit the scope of the embodiments of the present application. The size of the serial number of the above processes does not mean the order of execution, and the execution order of the processes should be determined according to their functions and inherent logic.

[0065] The calculation method of the assembly spacing of the adjacent light emitting modules of the vehicle lamp module provided in the embodiments of the present application is described in detail above, and the principles and implementation manners of the present application are described by applying specific examples. The above embodiment is only used to help understand the present application and its core idea; at the same time, for those skilled in the art, according to the idea of the present application, the specific implementation manner and application range will be changed, and the above description should not be understood as limiting the present application.
