[0042] It is understandable that the above description only describes the structure of the rearview display device located on one side of the vehicle width direction. In actual applications, the rearview display device located on the other side of the vehicle width direction also has the above structure and the same technical effect.

[0043] Regarding the connection between the acquisition unit 1 and the extension bracket 222, in one embodiment, please refer to [link to relevant documentation]. Figure 2, Figure 2 This diagram illustrates a structural schematic of the camera housing from a first-view perspective in an embodiment of the present invention. The camera housing 11 includes a mounting shell 111 and a connecting rod 112, with the camera module 12 mounted inside the mounting shell 111. The mounting shell 111 has a side wall, and the connecting rod 112 has a hollow structure. One end of the connecting rod 112 is connected to the side wall near the rear-view housing 22, and the other end of the connecting rod 112 is connected to the second end of the extension bracket 222. The shape of the second end of the extension bracket 222 is adapted to the connecting rod 112.

[0044] For example, the connecting rod 112 has an upward protrusion 1121 on the side near the rearview housing 22, and the second end of the extension bracket 222 has a downward recess 2221, which cooperates with the upward protrusion 1121. In one embodiment, such as Figure 2 and Figure 3 As shown, Figure 3 This diagram illustrates a rear-view rear shell structure in a first-view perspective according to an embodiment of the present invention. Figure 2 The upper protrusion 1121 of the middle connecting rod 112 is in the shape of a "┌". Figure 3 The second end of the extension bracket 222 is shaped like an "X". Specifically, the upper protrusion 1121 makes the end of the connecting rod 112 have a first stepped structure, with the first stepped surface 11211 facing downwards; the lower concave portion 2221 makes the second end of the extension bracket 222 have a second stepped structure, with the second stepped surface 22211 facing upwards; the first stepped structure and the second stepped structure overlap and cooperate, and the relative portions of the two on the axial direction of the extension bracket 222 have an arc-shaped curved surface structure. Specifically, the upper protrusion 1121 of the connecting rod 112 and the lower concave portion 2221 of the extension bracket 222 can be fixedly connected, and the central control structure of both the connecting rod 112 and the extension bracket 222 is provided with mutually cooperating locking structures (such as...). Figure 4 The first locking hole 2222 and Figure 8 The second locking hole 1122 allows the camera housing 11 and the rearview housing 22 to be fixed together by a locking screw passing through the first locking hole 2222 and the second locking hole 1122. The upper protrusion 1121 of the connecting rod 112 and the lower recess 2221 of the extension bracket 222 can also be rotatably connected. Both the connecting rod 112 and the extension bracket 222 have mutually cooperating rotating shaft structures (not shown in the figure) within their respective central control structures. In another embodiment, such as... Figure 6 and Figure 7 As shown, Figure 6 This diagram illustrates another structural schematic of the camera housing in a first-view perspective, according to an embodiment of the present invention. Figure 7This diagram illustrates another structural schematic of the rear shell in a first-view perspective according to an embodiment of the present invention. The upper protrusion 1121 of the connecting rod 112 also has a first-step structure, and a downwardly extending protrusion 1123 is also present on the first-step surface 11211 formed by the first-step structure; correspondingly, the lower recess 2221 of the extension bracket 222 has a second-step structure, and a groove structure 2223 adapted to the protrusion 1123 is also present on the second-step surface 22211 formed by the second-step structure. In the scheme where the upper protrusion 1121 and the lower recess 2221 rotate in conjunction, the acquisition unit 1 can rotate about the protrusion 1123 as an axis.

[0045] It is understood that, in addition to the above-described embodiments, the connecting rod 112 and the extension bracket 222 can also have other matching methods. For example, the connecting rod 112 has an upper protrusion 1121 in the shape of an "I" (not shown in the figure) on the side near the rearview housing 22, and the second end of the extension bracket 222 has a lower concave portion 2221 in the shape of an "I" (not shown in the figure). The "I" shaped structures of the connecting rod 112 and the extension bracket 222 are misaligned in the height direction. Alternatively, the connecting rod 112 may be in the shape of an "∟" (not shown in the figure) on the side near the rearview housing 22, and the second end of the extension bracket 222 may be in the shape of an "𠃍" (not shown in the figure) to match it.

[0046] Regarding the connection between the mounting shell 111 and the connecting rod 112 in the camera housing 11, in one embodiment, please refer to [link to relevant documentation]. Figure 2 The camera housing 11 also includes a connecting plate 113. The top of the mounting housing 111 protrudes towards the extension bracket 222 to form a protrusion 114. The connecting plate 113 connects the protrusion 114 and the connecting rod 112. The connecting rod 112 is connected to the protrusion 114 through the connecting plate 113, so that the mounting housing 111 and the connecting rod 112 form an integral whole, which improves the structural strength of the connecting rod 112.

[0047] Specifically, please refer to Figure 4 , Figure 4 This diagram illustrates a rearview housing structure in a second-view perspective according to an embodiment of the present invention. The extension bracket 222 in this embodiment is a curved bracket, with its central axis forming a smooth convex curve, extending upwards and in directions away from the rearview housing 22 at the end furthest from it.

[0048] Specifically, please refer to Figure 5 , Figure 5The figure shows a schematic diagram of the rearview front shell in a first viewing angle according to an embodiment of the present invention. As shown, the rearview front shell 21 has a planar structure. In a specific embodiment, the main electronic components of the rearview unit 2 are all located in the central region of the rearview rear shell 22. Therefore, the thickness of the rearview rear shell 22 gradually increases from the edge to the center in at least a part of the region.

[0049] This utility model embodiment also provides a vehicle equipped with the aforementioned rearview display device. Regarding the specific functions and structure of the rearview display device, please refer to the specific embodiments described above, which will not be repeated here. In this utility model embodiment, the rearview display device can be implemented in two ways within the vehicle:

[0050] In the first implementation, please refer to Figure 9 , Figure 9 This diagram illustrates a structural schematic of a rearview unit disposed on the center console in an embodiment of the present invention. The rearview unit 2 in the diagram is disposed on the vehicle's center console, and the rearview units 2 on both sides are connected to the center display unit 3 to form an integrated structure. This facilitates the installation of various components. Furthermore, since the center display unit 3 and the rearview unit 2 are integrated, the position of the rearview unit 2 is determined once the center display unit 3 is installed, eliminating the need for separate adjustments to the two components. Therefore, the position of the rearview mirror relative to the vehicle body is easily controlled, improving assembly efficiency and the positioning accuracy of the rearview mirror. Specifically, the rearview front shell 21 and the rearview rear shell 22 form a rearview housing. The rearview housing includes an upper edge 241, a first pair of side edges 242, a lower edge 243, and a second pair of side edges 245 connected in sequence. The first pair of side edges 242 is closer to the second pair of side edges 245 at one end near the upper edge 241 than at the other end. The upper edge 241 is inclined relative to the lower edge 243, and the end near the second pair of side edges 245 is farther from the lower edge 243 than at the other end. The extension bracket 222 extends toward the side where the first pair of side edges 242 are located.

[0051] In the second implementation, please refer to Figure 10 , Figure 10 This diagram illustrates a structural schematic of a rearview unit 2 disposed in a vehicle door according to an embodiment of the present invention. In this embodiment, since the interior space of the vehicle door is narrower than the interior space of the center console, the edge portion of the rearview unit 2 can be made with a curved transition, that is, the rearview unit 2 can be set to be thicker in the middle and the thickness gradually decreases from the center to the edge, in order to adapt to the thinner interior space of the edge portion of the vehicle door.

[0052] It should be noted that the use of step numbers (letters or numbers) to refer to certain specific method steps in this utility model is merely for the purpose of convenience and brevity in description, and is by no means intended to restrict the order of these method steps. Those skilled in the art will understand that the order of the relevant method steps should be determined by the technology itself and should not be unduly restricted by the existence of step numbers. Those skilled in the art can determine various permissible and reasonable order of steps based on the technology itself.

[0053] It is particularly important to note that the selection of these specific values, the relationships between them, and the ranges of values ​​requires not only a theoretical foundation far exceeding that of ordinary technicians in the field, but also creative attempts and selections based on the expected target design results, supplemented by several arduous experiments, in order to finally obtain the expected target results.

[0054] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0055] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
