DETAILED DESCRIPTION

[0027] With reference to the accompanying drawings and specific embodiments, the structure, composition, features and advantages of the vehicle lamp of the present invention and the vehicle having the same will be described below in an exemplary manner. However, all descriptions shall not be used to form any limitation on the present invention.

[0028] In addition, for any single technical feature described or implied in the embodiments mentioned in this document, or any single technical feature displayed or implied in the accompanying drawings, the present invention still allows for continued arbitrary combination or deletion between these technical features (or their equivalents) without any technical obstacles, and thus it should be considered that these more embodiments according to the present invention are also within the scope of the description of this document.

[0029] It should also be noted that the terms "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships of the vehicle lights and their components as shown in the accompanying drawings. They are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present disclosure.

[0030] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.

[0031] In the description of the present disclosure, “plurality” means at least two, such as two, three or more, etc., unless otherwise clearly and specifically defined.

[0032] from Figure 1 as well as Figure 2 It can be seen that the vehicle lamp 1 of the present invention comprises a vehicle lamp base 11 and a lampshade 2. The vehicle lamp base 11 is used to install the vehicle lamp 1 on a vehicle, and the lampshade 2 is installed on the vehicle lamp base 11. A dot matrix screen 3 is installed inside the lampshade 2. The dot matrix screen 3 can be used as a functional signal light to remind surrounding vehicles and pedestrians of the vehicle's upcoming driving intentions, including turning, braking, parking, etc. The dot matrix screen 3 can also be used as an information interaction screen to display interactive information such as text and patterns.

[0033] Specifically, Figure 2 As shown, Figure 2 The lamp 1 in the figure has the right half of the lampshade removed, and it can be seen that the dot matrix screen 3 of the present invention includes a plurality of circuit plates 4, which are arranged side by side and arranged along the inner shape and curvature of the lampshade 2.

[0034] Each circuit board 4 is provided with an LED light source point 44, and each LED light source point 44 can be controlled individually, so that a functional signal or interactive information such as text, pattern, etc. can be displayed through a combination of multiple LED light source points 44. The multiple circuit boards 4 are arranged side by side and along the inner shape and curvature of the lampshade 2, so that the distance between each LED light source point 44 and the lampshade 2 can be the same, so that the lighting effect of each LED light source point 44 through the lampshade 2 can be consistent, thereby realizing the interaction of vehicle functional signals and information.

[0035] The multiple circuit boards 4 are more durable and less prone to damage than the flexible screen panel, and the multiple circuit boards 4 can be installed and disassembled separately, which is convenient for maintenance and replacement. In addition, the low price of the circuit boards 4 can save the production cost of the dot matrix screen 3.

[0036] In order to further ensure the lighting effect of the LED light source points 44 of the dot matrix screen 3, as Figure 3 As shown, the present invention defines the spacing between two adjacent LED light source points 44 in the arrangement direction of the circuit board 4 to be the same as d, that is, the distance between two adjacent LED light source points 44 on the same circuit board 4, and the distance between two adjacent LED light source points 44 between two adjacent circuit boards 4 are all the same as d, so as to evenly distribute the LED light source points 44 in the arrangement direction, thereby visually eliminating the dark area of ​​light formed by the interval between the two circuit boards 4, making the interactive information display smoother.

[0037] It is understandable that the smaller the distance between two adjacent LED light source points 44 , that is, the denser the dot matrix arrangement of the LED light source points 44 , the better the interactive information effect of the combined light display of multiple LED light source points 44 .

[0038] The LED light source point 44 is installed on the circuit board 4, and the minimum distance L from the edge of the circuit board 4 is 0.4 mm. In order to make the circuit board 4 fit the shape of the inside of the lampshade 2, the minimum distance s between two adjacent circuit boards 4 is 0.5 mm.

[0039] Therefore, further, the spacing d between two adjacent circuit plates 4 can be set to the sum of the distance L between the edge of the LED light source point 44 and the circuit plate 4 and the distance s between the circuit plates 4, that is, d=L+S+L=1.3 mm, that is, the distance d between the LED light source points 44 is set to 1.3 mm. The spacing between the circuit plates 4 set in this way can ensure that the LED light source points 44 are arranged as densely as possible within the limited space of the circuit plate 4, while eliminating the visual dark area, making the interactive information display effect more delicate.

[0040] It should be noted that the circuit board 4 of the dot matrix screen 3 of the headlight 1 of the present invention is installed on the headlight base 11 (such as Figure 7 as shown).

[0041] The dot matrix screen support 5 has the same internal cross-sectional shape as the lampshade 2 (eg Figure 2 and Figure 4 as shown), has an arc.

[0042] The dot matrix screen bracket 5 includes a circuit board mounting portion 7, which is used to mount the circuit board 4, and the circuit board mounting portion 7 is arranged at different heights to ensure the installation angle of the circuit board 4 and the installation spacing between each other, thereby ensuring that the circuit board 4 is arranged along the internal shape structure of the lampshade 2 while ensuring the spacing between the LED light source points 44 between two adjacent circuit boards 4.

[0043] Specifically, in Figure 1The vehicle lamp in the embodiment is a vehicle position lamp. As can be seen from the figure, the lampshade 2 of the dot matrix screen of the position lamp is L-shaped. Therefore, the shapes of the dot matrix screen 3 and the dot matrix screen bracket 5 are both L-shaped (such as Figure 4 and Figure 5 As shown), to fit the internal cross-sectional shape of the lampshade 2.

[0044] like Figure 4 As shown, the dot matrix screen 3 is composed of three circuit plates 4, and the shapes of the three circuit plates 4 are different, such as L-shaped and trapezoidal shapes, and the width gradually decreases from one end to the other end to conform to the cross-sectional shape of the lampshade 2. In an optional embodiment, the number of circuit plates 4 of the dot matrix screen 3 is not limited, and can be multiple, and can be set according to the shape of the actual lampshade 2.

[0045] The LED light source points 44 on the circuit board 4 are also evenly distributed according to the shape of the lampshade 2, so that the light of each LED light source point 44 can pass through the lampshade 2 to achieve the desired lighting effect. There are no redundant LED light source points 44, and there is no mutual interference between the LED light source points 44, so there is no need for shading.

[0046] Combination Figure 4 and Figure 5 It can be seen that a mounting hole 41 is provided on one side of the circuit board 4. Figure 5 As shown, the dot matrix screen bracket 5 has a first surface 54 and a second surface 55 . The first surface 54 of the dot matrix screen bracket 5 is provided with a circuit board mounting portion 7 . The circuit board mounting portion 7 includes a mounting groove 71 .

During installation, the bolt is inserted into the corresponding mounting groove 71 through the mounting hole 41 to fix the circuit board 4.

[0048] Furthermore, if Figure 4 As shown, the circuit board 4 is provided with a limiting hole 42 near the mounting hole 41. Figure 5 As shown, the circuit board mounting portion 7 further includes a limiting pin 72 , and the limiting pin 72 can pass through the limiting hole 42 and be positioned in the limiting hole 42 .

[0049] The limiting hole 42 may be circular, conforming to the shape of the limiting pin 72. Optionally, the limiting hole 42 may also be elliptical, and the limiting pin 72 may be limited to any position within the range defined by the elliptical limiting hole 42 to adjust the installation position and angle of the circuit board 4 to meet the installation spacing requirements.

[0050] In other embodiments, the shape of the limiting hole 42 is not limited, and may be a polygon, an irregular shape, etc., as long as it can cooperate with the limiting pin 72 to limit the position.

[0051] Furthermore, a mounting portion 43 (such as Figure 4 As shown in FIG. 4 , the mounting portion 43 extends out of the edge of the circuit board 4 . Accordingly, the first surface 54 of the dot matrix screen bracket 5 may also be provided with a fixing boss 73 and a fixing rib 74 .

[0052] The fixing boss 73 is disposed at the edge of the dot matrix screen bracket 5 and protrudes from the first surface 54 . The fixing boss 73 has a mounting through hole 75 to correspond to the mounting portion 43 of the circuit board 4 .

[0053] The fixing ridge 74 is installed at the edge of the first surface 54 near the fixing boss 73 . The fixing ridge 74 is used to abut against the edge of the circuit board 4 . The fixing ridge 74 can cooperate with the fixing boss 73 to further define the position of the circuit board 4 .

[0054] During installation, if Figure 7 As shown, the mounting portion 43 of the circuit plate 4 can extend into the mounting through hole 75 and be snapped onto the fixing boss 73 , while the edge of the circuit plate 4 abuts against the fixing boss 73 , thereby fixing the side edge of the circuit plate 4 .

Specifically, the dot matrix screen bracket 5 is provided with a heat dissipation port 53 corresponding to each circuit board 4.

[0058] The dot matrix screen bracket 5 is provided with a wire outlet slot 9, combined with Figure 6It can be seen that the wire outlet groove 9 is recessed toward the second surface 55, and the edge of the wire outlet groove 9 is provided with a wire harness protrusion 92 and a wire harness clamping portion 93. Specifically, the wire harness protrusion 92 protrudes toward the first surface 54, and is used to guide the wire harness from the wire outlet groove 9 to the second surface 55, and to limit the wire harness within the notch range of the wire outlet groove 9 to regularize the wire harness. The side of the wire harness clamping portion 93 extends toward the notch of the wire outlet groove 9, and is used to clamp the wire harness, thereby achieving the purpose of wire harness arrangement.

[0059] Alternatively, if Figure 6 As shown, the dot matrix screen bracket 5 may also be provided with a harness groove 91 near the wire outlet groove 9 , and the wire outlet groove 9 is lower than the harness groove 91 , and the harness groove 91 is used to guide the wire harness to the wire outlet groove 9 .

[0060] In an optional embodiment, the dot matrix screen bracket 5 may also be provided with a wire harness organizing portion 8 , which protrudes toward the second surface 55 to clamp the wire harness at the second surface 55 .

[0061] from Figure 5 It can also be seen that the dot matrix screen bracket 5 also has a base mounting portion 6, and the base mounting portion 6 can be recessed toward the second surface 55 or protruded toward the first surface 54. Figure 7 It can be seen that the depression and protrusion of the base mounting portion 6 correspond to the shape of the lamp base 11. The base mounting portion 6 is provided with a base mounting hole 61, through which a bolt can pass to mount the dot matrix screen bracket 5 on the lamp base 11 during installation.
