DETAILED DESCRIPTION

[0030] The technical solutions in the present application will be described clearly and exhaustively below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B: "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0031] Hereinafter, the terms "first" and "second" are used only for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features.

[0032] In related art, a camera module includes a bracket, a lens, and a light-emitting assembly. Both the lens and the light-emitting assembly are mounted on the bracket. The light-emitting assembly includes a light-emitting diode (LED) light board and light beads mounted on the light board. A light-transmitting plate is connected to the bracket to allow light emitted by the light beads to be transmitted.

[0033] However, in the above-mentioned camera module, the fill light range of the lamp beads is relatively large, which may cause overexposure of certain areas within the lens field of view, thereby causing loss of details in the video data captured by the camera module.

[0034] Based on this, the embodiments of the present application provide a camera module and a vehicle that can reduce the fill light range of the lamp beads. In this way, it can avoid overexposure of certain areas within the lens field of view to a certain extent, thereby improving the integrity of the video data captured by the camera module.

[0035] The embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0036] Please combine Figures 1 to 3 , Figure 1 This is a structural diagram of a first partial structure of a camera module provided in an embodiment of the present application, Figure 2 for Figure 1 Schematic diagram of the structure along direction A, Figure 3 This is an exploded view of a second partial structure of a camera module provided in an embodiment of the present application. As shown in the figure, this embodiment provides a camera module, including a bracket assembly 1, a light emitting assembly 2, a first circuit board 3 and a light concentrator 4.

[0037] In this embodiment, the bracket assembly 1 includes a bracket 11 and a cover plate 12 connected together, and the cover plate 12 is a light-transmitting cover plate. For example, the cover plate 12 can be made of glass. Here, there is no specific limitation on the material of the cover plate 12.

[0038] Furthermore, the light-emitting assembly 2 includes a lamp board 21 and lamp beads 22. The lamp board 21 is disposed on and electrically connected to the first circuit board 3. The lamp beads 22 are disposed on the side of the lamp board 21 facing away from the first circuit board 3. The lamp board 21 may be an LED lamp board, and the lamp beads 22 may be round, spherical, square, or the like. In the specific implementation of this embodiment, the lamp beads 22 are spherical. Of course, in other implementations, the lamp beads 22 may also have other shapes, and the shape of the lamp beads 22 is not specifically limited herein.

[0039] From the above, it can be seen that since the fill light range of the lamp beads in the related art is large, the camera module provided in this embodiment is provided with the following Figure 4 The light concentrating element 4 shown, Figure 4An exploded view of the third partial structure of the camera module provided in the embodiments of the present application is shown. By providing the light collecting member 4, the light collecting range of the lamp bead 22 is reduced by using the refraction principle of light. Therefore, it can be understood that the light collecting member 4 also needs to be transparent, i.e., the light collecting member 4 is a transparent member. Of course, the material of the light collecting member 4 can be consistent with the material of the cover plate 12. In this regard, the material of the light collecting member 4 is not specifically limited.

[0040] Please continue to combine Figure 5 and Figure 6 , Figure 5 A perspective view of the support of the camera module provided in the embodiments of the present application is shown, Figure 6 A plan view of the fourth partial structure of the camera module provided in the embodiments of the present application is shown.

[0041] Specifically, the light collecting member 4 includes a connecting portion 41 and a light collecting portion 42. The connecting portion 41 is connected to the cover plate 12, and the light collecting portion 42 is connected to the side of the connecting portion 41 facing the first circuit board 3. The light collecting portion 42 is formed with a relief groove 421 for avoiding the lamp bead 22, as shown in Figure 6 The radial dimension of the light collecting portion 42 decreases in the front-to-back direction, i.e., the direction from the cover plate 12 to the first circuit board 3. In this way, by limiting the size of the light collecting portion 42, the light emitted by the lamp bead 22 can be refracted, thereby reducing the light collecting range of the lamp bead 22, avoiding overexposure in some areas within the field of view of the lens, and improving the integrity of the video material captured by the camera module, thereby improving the use performance of the camera module.

[0042] It should be noted that in the front-to-back direction, the front refers to the side of the camera module facing the target object after assembly, and the back refers to the side of the camera module away from the target object. For details, please refer to the front-to-back direction in Figures 2 to 5 .

[0043] In some specific embodiments, the support 11 includes a support body 111 and a protruding portion 112. The support body 111 is formed with a first mounting cavity 1111 and a second mounting cavity 1112 arranged at intervals. Part of the structure of the light collecting member 4 is located in the first mounting cavity 1111, and part of the structure of the lens (not shown in the figure) is located in the second mounting cavity 1112. The protruding portion 112 is arranged on the side of the support body 111 away from the first circuit board 3, and the cover plate 12 is formed with a positioning groove 121 for embedding the protruding portion 112, and the positioning groove 121 is arranged around part of the connecting portion 41.

[0044] As shown in Figure 4As shown, since the connecting portion 41 is connected with the cover plate 12 through the connecting short plate 13, the positioning groove 121 has the sidewall of the connecting short plate 13 at the starting end and the ending end of the extending direction of the positioning groove 121. In addition, it should be noted that the support 11 can be a plastic part. In the specific embodiment of the present embodiment, the support 11, the cover plate 12 and the light collecting part 4 are integrally formed. Thus, during the process of integral forming, the protruding part 112 interferes with the connecting short plate 13, and part of the structure of the protruding part 112 is integrated with the connecting short plate 13. For details, please refer to Figure 1 .

[0045] Specifically, the support body 111 includes a supporting part 1113 and a separating part 1114. The supporting part 1113 extends along the contour of the cover plate 12 and is connected with the cover plate 12. The cover plate 12 has a positioning cavity 122 matched with the supporting part 1113. The assembly efficiency between the support 11 and the cover plate 12 can be improved by the cooperation of the positioning cavity 122 and the supporting part 1113.

[0046] The protruding part 112 is connected to the supporting part 1113. The separating part 1114 is connected to the side of the supporting part 1113 facing the first circuit board 3, so as to separate the first mounting cavity 1111 and the second mounting cavity 1112.

[0047] In some specific embodiments, in order to improve the structural strength of the support 11, the opposite sides of the separating part 1114 are provided with first reinforcing plates 1115. In this way, the structural strength of the support 11 can be improved, and the structural strength of the support assembly 1 can be improved.

[0048] It can be understood that, since the volume of the lens is large, the occupied space of the second mounting cavity 1112 should be larger than that of the first mounting cavity 1111.

[0049] Therefore, in some specific embodiments, the separating part 1114 is an arc-shaped plate, and the middle part of the separating part 1114 protrudes towards the side of the first mounting cavity 1111. In this way, the inner volume of the second mounting cavity 1112 is larger than that of the first mounting cavity 1111, so as to facilitate the installation of the lens.

[0050] Further, the side of the supporting part 1113 facing the first circuit board 3 is also provided with a plurality of second reinforcing plates 1116 distributed at intervals. The second reinforcing plates 1116 extend along the contour of the cover plate 12. At least one of the second reinforcing plates 1116 is provided with a weight-reducing hole 1117. In this way, the structural strength of the support 11 can be further improved by the plurality of second reinforcing plates 1116.

[0051] Specifically, the support 11 has a length direction and a width direction, and the length direction of the support 11 is perpendicular to the width direction of the support 11. Figure 1 ,Figures 3 to 5 The xx-axis direction is consistent with the width direction of the bracket 11. Figure 1 、 Figures 2 to 5 The yy-axis direction is consistent.

[0052] In this embodiment, the plurality of second reinforcing plates 1116 include two curved reinforcing plates 1118, which are distributed along the length of the bracket 11 at opposite ends of the support portion 1113, with the two curved reinforcing plates 1118 protruding in opposite directions. Each curved reinforcing plate 1118 is provided with a weight-reducing hole 1117. The inner wall of one of the two curved reinforcing plates 1118 forms a portion of the sidewall of the first mounting cavity 1111, while the inner wall of the other of the two curved reinforcing plates 1118 forms a portion of the sidewall of the second mounting cavity 1112.

[0053] Furthermore, the plurality of second reinforcing plates 1116 further include short reinforcing plates 1119 distributed on both sides of the curved reinforcing plate 1118. One of the two short reinforcing plates 1119 is in close contact with and connected to the curved reinforcing plate 1118, while a gap exists between the other of the two short reinforcing plates 1119 and the curved reinforcing plate 1118. Furthermore, the inner wall surfaces of the short reinforcing plates 1119 can form portions of the side walls of the first installation cavity 1111 and portions of the side walls of the second installation cavity 1112.

[0054] It is understandable that in order to install the lens, the camera module provided in this embodiment should also include a base (not shown in the figure). The base is snapped together with the bracket 11 to form an installation space for accommodating the lens. Among them, the second installation cavity 1112 is formed as part of the installation space. In order to snap the bracket 11 and the base together, the side of the support portion 1113 facing the first circuit board 3 is also provided with two snap-in plates 1120 arranged opposite to each other along the width direction of the bracket 11, and the opposite sides of the two snap-in plates 1120 are provided with snap-in protrusions 1121 that are snap-in together with the base. Of course, in some other embodiments, the bracket 11 can also be of other shapes, and here, there is no specific limitation on the shape and structure of the bracket 11.

[0055] Please continue to combine Figure 7 , Figure 7 for Figure 6 Cross-sectional view along direction BB. As shown in the figure, in order to improve the focusing effect of the focusing portion 42, that is, to reduce the amount of light loss during the refraction process. In this embodiment, the shape of the focusing portion 42 is further restricted. Specifically, the outer wall surface of the focusing portion 42 is a revolution surface, and any point on the revolution surface satisfies the following formula in the two-dimensional coordinate system: y = -0.012 × x 3 -0.68×x 2 -12.65×x-68.25.

[0056] Referring to Figure 7 The outer wall surface of the light collecting portion 42 is an arc-shaped wall surface. In this way, by limiting the shape of the outer wall surface of the light collecting portion 42, the loss of light in the refraction process can be reduced, so that the camera module maintains good use performance.

[0057] For example, in a two-dimensional coordinate system, if x is 1, the coordinates of the point are (1, -81.592); if x is 2, the coordinates of the point are (2, -96.366). Here, the positions of the points on the outer wall surface of the light collecting portion 42 in the two-dimensional coordinate system are not exemplified one by one.

[0058] As can be seen from the above, in order to avoid the lamp bead 22, the light collecting portion 42 is provided with an avoidance groove 421. Since the lamp bead 22 is a spherical lamp bead in the embodiment, in the specific implementation manner of the embodiment, the cross-sectional shape of the avoidance groove 421 is circular.

[0059] Further, the rear end of the avoidance groove 421 forms a groove opening 4211 of the avoidance groove 421. In the direction from the groove opening 4211 to the groove bottom of the avoidance groove 421, the diameter of at least part of the groove section of the avoidance groove 421 gradually decreases. In this way, on the one hand, the lamp bead 22 can be avoided, and on the other hand, the influence of the setting of the avoidance groove 421 on the structural strength of the light collecting member 4 can be avoided, so that the structural strength of the light collecting member 4 is high.

[0060] Further, in the specific implementation manner of the embodiment, in the direction from the groove opening 4211 to the groove bottom of the avoidance groove 421, the diameter of the avoidance groove 421 gradually decreases, and the longitudinal cross-sectional shape of the avoidance groove 421 is isosceles trapezoidal. It should be noted that in some other implementation manners, the shape of the avoidance groove 421 can also be other shapes. For example, the cross-sectional shape is square, and the specific shape of the avoidance groove 421 is determined according to the specific shape of the lamp bead 22, which is not limited here.

[0061] For example, if the light supplementing range of the lamp bead of the camera module in the related art is 60 degrees, the light supplementing range of the lamp bead 22 in the camera module provided in the embodiment can be reduced to 30 degrees.

[0062] The embodiment also provides a vehicle, which comprises a multimedia host and the camera module described above; the camera module further comprises a second circuit board electrically connected with the first circuit board 3, and the second circuit board is electrically connected with the multimedia host. It should be noted that the structure of the camera module has been described in detail in the above embodiment, and will not be repeated here.

[0063] In addition, the vehicle provided by the embodiment should also include other components or modules capable of enabling the vehicle to be normally used, and here, the other components or modules are not introduced one by one.

[0064] The vehicle provided by the embodiment has better use performance by using the camera module in the above embodiment.

[0065] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
