[0002] An electronic rearview mirror is a system consisting of a camera and a monitor. Within a specified field of view, it is required to clearly see the rear and side views of the vehicle. It is a new type of indirect vision device, which the national standard calls "camera-monitor system" or CMS for short.
[0003] To meet actual transportation needs, commercial vehicles may carry standard cargo boxes with a width of no more than 2.55 meters or extra-wide cargo boxes with a width of 3.2 meters. However, the current fixed structure for mounting the camera components of electronic rearview mirrors on the sides of commercial vehicles is designed according to the size of standard cargo boxes. Therefore, when a commercial vehicle carries an extra-wide cargo box, the edges of the left and right sides of the extra-wide cargo box extend significantly beyond the field of vision of the electronic rearview mirror, forming obvious blind spots. During vehicle operation, the rearview mirror's field of vision is obstructed by the extra-wide cargo box, making it difficult for the driver to fully observe the situation of vehicles approaching from behind and to the sides, resulting in serious safety hazards during driving.

[0007] In some embodiments, the camera mounting housing has a cavity for accommodating a camera assembly, and the inner surface of the bottom of the camera mounting housing has a first protrusion extending toward the interior of the camera mounting housing, wherein the third, fourth, and fifth connecting holes all pass through the first protrusion.
[0008] In some embodiments, the camera mounting housing has a cavity for receiving a camera assembly, and the outer surface of the bottom of the camera mounting housing has a second protrusion extending toward the distance from the camera mounting housing, through which the third connection hole passes.
[0009] In some embodiments, the connecting rod includes a hollow region, and the upper end face of the connecting rod has a first through hole for the second protrusion to pass through, the second protrusion extending into the hollow region of the connecting rod through the first through hole; the first connecting hole is formed on the lower end face of the connecting rod.

[0014] This utility model also discloses an electronic rearview mirror for commercial vehicles, including a camera assembly and the aforementioned adjustment mechanism for the electronic rearview mirror for commercial vehicles.
[0015] Compared with the prior art, the adjustment mechanism and electronic rearview mirror for commercial vehicles provided by this utility model have the following advantages:
[0016] 1. The adjustment mechanism and electronic rearview mirror for commercial vehicles provided by this utility model address the issue that the width of the cargo box on a commercial vehicle affects the field of vision of the electronic rearview mirror. In this utility model, by rotatably connecting the two ends of the connecting rod to the mounting base and the camera mounting housing respectively, the angle of the axis of the connecting rod relative to the length of the vehicle body and the optical axis of the camera lens can be adjusted to a suitable angle when the commercial vehicle carries cargo boxes of different widths. This ensures that the field of vision of the electronic rearview mirror of the commercial vehicle is always good, allowing the driver to better observe the situation of vehicles approaching from behind and to the sides, thus improving driving safety.
[0017] 2. The adjustable connection structure of the electronic rearview mirror for commercial vehicles and the electronic rearview mirror for commercial vehicles provided by this utility model has two states, each state matching a cargo box. Specifically, the first connecting hole is always coaxially connected to the third connecting hole through the first bolt assembly. When it is necessary to rotate the camera fixing shell relative to the connecting rod with the center of the first connecting hole as the center to adjust the setting angle of the camera fixing shell, the second connecting hole can be connected to the fourth connecting hole through the second bolt assembly to adapt to the width of the standard cargo box; the second connecting hole can be connected to the fifth connecting hole through the second bolt assembly to adapt to the width of the extra-wide cargo box.
[0018] 3. The adjustment mechanism and electronic rearview mirror for commercial vehicles provided by this utility model can increase the depth of the third, fourth and fifth connecting holes opened thereon by the first and second protrusions, thereby improving the structural strength at that point and preventing cracking at the opening when connected by the first and second bolt assemblies.

[0019] 4. The adjustment mechanism and electronic rearview mirror for commercial vehicles provided by this utility model have the camera component set in the cavity formed by the bottom cover and the top cover to avoid damage to the camera component during driving. At the same time, the wires of the camera component can extend into the interior of the commercial vehicle through the second through hole, the third through hole and the hollow area of the connecting rod in sequence to avoid the wires being exposed.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0036] In one embodiment, such as Figures 1-4 As shown, this embodiment discloses a specific implementation of an electronic rearview mirror for commercial vehicles, including a camera assembly 4 and an adjustment mechanism for the electronic rearview mirror. The adjustment mechanism can be directly switched between two states, so that when the commercial vehicle carries cargo boxes of different widths, the angle of the axis B of the connecting rod relative to the length direction A of the commercial vehicle and the optical axis C of the lens of the camera assembly 4 can be adjusted to a suitable angle, thereby ensuring that the electronic rearview mirror of the commercial vehicle always has a good field of vision, allowing the driver to better observe the situation of vehicles approaching from behind and to the sides, thus improving driving safety.
[0037] Specifically, such as Figures 1-4 As shown, the adjustment mechanism for the electronic rearview mirror of a commercial vehicle is used to mount the camera assembly 4 on the outer side surface of the commercial vehicle. It includes a mounting base 1, a camera mounting bracket, and a connecting rod 2. The mounting base 1 is connected to the outer side surface of the commercial vehicle. The camera assembly 4 is mounted on a camera mounting housing 3. The first end of the connecting rod 2 (i.e....) Figure 1 The right end of the connecting rod 2 is rotatably connected to the mounting base 1, and the second end of the connecting rod 2 (i.e., Figure 1 The left end of the connecting rod 2 is rotatably connected to the camera mounting housing 3. The axis B of the connecting rod forms a first angle with the length direction A of the commercial vehicle. The first angle can be switched between a first preset angle and a second preset angle. The axis B of the connecting rod forms a second angle with the optical axis C of the lens of the camera assembly 4. The second angle can be switched between a third preset angle and a fourth preset angle. The first preset angle is less than the second preset angle, the third preset angle is less than the fourth preset angle, and the first preset angle, the second preset angle, the third preset angle and the fourth preset angle are all less than or equal to 90°.
[0038] like Figures 5-8As shown, the second end of the connecting rod 2 is rotatably connected to the camera mounting housing 3 through an adjustable connecting structure. Specifically, the camera mounting housing 3 includes a bottom cover 3a and a top cover. The bottom cover 3a and the top cover together form a cavity for accommodating the camera assembly 4. The bottom cover 3a and the top cover are detachably connected, which facilitates the installation of the camera assembly 4 and prevents the camera assembly 4 from being damaged by collision during driving.
[0039] In other specific embodiments, the camera mounting housing 3 can also be assembled from different housing components, or the camera assembly 4 can be directly connected to the outside of the camera mounting housing 3, which will not be elaborated here.
[0040] like Figure 6 As shown, the adjustable connection structure includes a first connection hole 2b and a second connection hole 2c opened at the second end of the connecting rod 2, and the first connection hole 2b and the second connection hole 2c pass through the connecting rod 2 in a direction perpendicular to the connecting rod 2.
[0041] like Figure 5 and Figures 7-8 As shown, the adjustable connection structure also includes a through third connection hole 3c, a fourth connection hole 3e and a fifth connection hole 3f opened at the bottom of the camera mounting housing 3. The third connection hole 3c is coaxially arranged with the first connection hole 2b and connected by the first bolt assembly.
[0042] Figure 1 and Figure 3 The two different states of the adjustment mechanism for the electronic rearview mirror in commercial vehicles were demonstrated.
[0043] like Figure 3 As shown, when a commercial vehicle carries a standard cargo box, the second connecting hole 2c and the fourth connecting hole 3e are coaxially arranged and connected by the second bolt assembly. At this time, the first included angle is the first preset angle and the second included angle is the third preset angle.
[0044] like Figure 1 As shown, when a commercial vehicle carries an extra-wide cargo box, the second connecting hole 2c and the fifth connecting hole 3f are coaxially arranged and connected by the second bolt assembly. At this time, the first included angle is the second preset angle, and the second included angle is the fourth preset angle.
[0045] contrast Figure 1 and Figure 3 The two different states of the adjustment mechanism for the electronic rearview mirror of the commercial vehicle on display are clearly... Figure 1 In this state, the field of view of camera component 4 is compared to Figure 3 A broader perspective.
[0046] More preferably, in one embodiment, such as Figure 7As shown, the inner surface of the bottom of the camera mounting housing 3 has a first protrusion 3b extending toward the interior of the camera mounting housing 3. That is, the bottom of the bottom cover 3a has a first protrusion 3b extending toward the interior of the camera mounting housing 3. The aforementioned third connecting hole 3c, fourth connecting hole 3e and fifth connecting hole 3f all pass through the first protrusion 3b, thereby increasing the depth of the third connecting hole 3c, fourth connecting hole 3e and fifth connecting hole 3f opened thereon, improving the structural strength at this point, and preventing cracking at the opening when connected by the first bolt assembly and the second bolt assembly.
[0047] In other specific embodiments, only one or two of the third connecting hole 3c, the fourth connecting hole 3e, and the fifth connecting hole 3f may be provided on the first protrusion 3b, while the others may be directly provided on the bottom cover 3a. This can also serve to increase the structure at the corresponding holes, which will not be elaborated here.
[0048] More preferably, in one embodiment, such as Figure 1 As shown, the outer surface of the bottom of the camera mounting housing 3 has a second protrusion 3g extending away from the camera mounting housing 3, that is, the outer surface of the bottom of the bottom of the bottom cover 3a has a second protrusion 3g extending away from the camera mounting housing 3. The third connecting hole 3c passes through the second protrusion 3g, thereby further improving the structural strength at the third connecting hole 3c.
[0049] More preferably, in one embodiment, such as Figure 6 and Figure 8 As shown, the connecting rod 2 includes a hollow region. A first through hole is provided on the upper end face of the connecting rod 2 for the aforementioned second protrusion 3g to pass through. The second protrusion 3g extends into the hollow region of the connecting rod 2 through the first through hole. At this time, the first connecting hole 2b is located on the lower end face of the connecting rod 2. During the installation of the camera mounting housing 3 on the connecting rod 2, the second protrusion 3g can extend into the first through hole, thereby achieving rapid positioning of the first connecting hole 2b and the third connecting hole 3c, improving installation efficiency.
[0050] More preferably, in one embodiment, such as Figure 6 and Figure 7 As shown, a second through hole 3d is also provided at the bottom of the camera mounting housing 3, that is, a second through hole 3d is also provided at the bottom of the bottom housing, and a third through hole 2a is also provided at the upper end face of the connecting rod 2.
[0051] When a commercial vehicle carries a standard or extra-wide cargo box, the projections of the second through hole 3d and the third through hole 2a in the vertical direction always overlap. The wires 5 of the camera assembly 4 are connected to the interior of the commercial vehicle through the hollow area of the second through hole 3d, the third through hole 2a and the connecting rod 2 in sequence, so as to avoid the wires 5 being exposed.
[0052] In other specific embodiments, a hollow pipe through which the power supply line 5 passes can also be set up, and the two ends of the hollow pipe can be connected to the interior of the commercial vehicle and the cavity of the camera mounting housing 3, respectively. Thus, the wires 5 of the camera assembly 4 can also be connected to the interior of the commercial vehicle through the hollow pipe. This will not be elaborated here.
[0053] More preferably, in order to increase the structural strength at the second through hole 3d, the first protrusion 3b extends to the second through hole 3d, so that the second through hole 3d penetrates the first protrusion 3b in a direction perpendicular to the bottom of the camera mounting housing 3, that is, the second through hole 3d penetrates the first protrusion 3b in a direction perpendicular to the bottom cover 3a.
[0054] Even better, the connection between the wall of the second via 3d and the inner end face of the first protrusion 3b is smooth, which can reduce the friction and damage to the wire 5 when it passes through the second via 3d. In addition, the inner wall of the second via 3d can also be designed to have a smooth transition, which can also reduce the friction and damage to the wire 5 when it passes through the second via 3d, which will not be elaborated here.
