Description

Technical Field

[0001] This utility model relates to the field of electronic rearview mirror structure, and further to a baffle and electronic rearview mirror for commercial vehicles. Background Technology

[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] Although it has many advantages over traditional glass rearview mirrors, such as reducing direct and indirect blind spots, providing better visibility in adverse conditions, and improving driving safety, electronic rearview mirrors can provide drivers with clearer and more effective indirect visibility in complex environments such as at night, in rainy or snowy weather, and when turning, thanks to advanced sensor and optical lens technology and optimized image algorithms.

[0004] However, when driving at night, the electronic rearview mirror's display is brighter than the ambient light outside the vehicle due to the darkness outside. This causes reflective virtual images to form on the driver's side side window and the passenger side windshield, affecting the driver's direct view of the outside world and potentially leading to driver misoperation and causing driving safety issues. Utility Model Content

[0005] The purpose of this utility model is to provide a baffle and electronic rearview mirror for commercial vehicles, which solves the problem in the prior art where the display forms a reflective virtual image area on the driver's side side window and the passenger side windshield, affecting the driver's direct vision outside the vehicle and causing driving safety issues. By using the baffle of this commercial vehicle electronic rearview mirror, the reflection of the display is physically blocked, preventing the display from forming a reflective virtual image on the driver's side side window and the passenger side windshield, optimizing nighttime driving visibility and improving driving safety.

[0006] To achieve the above objectives, this utility model provides a baffle and an electronic rearview mirror for commercial vehicles. The baffle is connected to a display screen support, and the bottom of the display screen is mounted on the display screen support. The baffle includes a shielding plate, a conforming plate, and a limiting plate connected in sequence. The baffle is connected to the display screen support through the conforming plate, and the conforming plate conforms to the contours of the display screen and the display screen support at corresponding locations. The limiting plate conforms to the end face of the display screen support away from the display screen. The vertical distance from the end of the shielding plate away from the conforming plate to the screen surface of the display screen is 50mm-100mm.

[0007] In some embodiments, the shield is located on the side of the display screen and extends contourally along the corresponding side of the display screen and covers the corresponding side of the display screen.

[0008] In some embodiments, the thickness of the baffle plate, conformal plate, and limiting plate is 5mm-10mm.

[0009] In some embodiments, the conformal plate has a connecting hole, and the baffle is detachably connected to the display screen support through the connecting hole and the connector.

[0010] In some embodiments, there are multiple connection holes, and the connection holes are arranged along the extension direction of the corresponding side of the display screen support.

[0011] In some embodiments, the conformal plate protrudes in a direction away from the display screen support, corresponding to the position of the connecting hole, to form a first protrusion. The inner surface of the first protrusion has a first preset distance from the display screen support, and the connecting hole is located on the first protrusion.

[0012] In some embodiments, stiffening ribs are provided on both sides of the first protrusion.

[0013] In some embodiments, the baffle and the electronic rearview mirror for commercial vehicles further include: a second protrusion, wherein the second protrusion is formed by the baffle and the conformal plate protruding synchronously in a direction away from the display screen support, and the inner surface of the second protrusion has a second preset distance from the display screen support, wherein the second preset distance is greater than the first preset distance;

[0014] In some embodiments, at least one side of the first protrusion is provided with the second protrusion; and / or; at least a portion of the edge of the second protrusion transitions to the baffle via an inclined surface.

[0015] This utility model also provides an electronic rearview mirror, including a monitor assembly and a camera. The monitor assembly includes the aforementioned baffle, display screen, and display screen bracket for a commercial vehicle electronic rearview mirror. The camera is communicatively connected to the display screen. When the monitor assembly is installed on the driver's side of the commercial vehicle, the baffle for the commercial vehicle electronic rearview mirror is located between the display screen and the side window glass; and / or, when the monitor assembly is installed on the passenger side of the commercial vehicle, the baffle for the commercial vehicle electronic rearview mirror is located between the display screen and the windshield.

[0016] Compared with the prior art, the baffle and electronic rearview mirror for commercial vehicles provided by this utility model have the following beneficial effects:

[0017] 1. The present invention provides a baffle and electronic rearview mirror for commercial vehicles. The baffle for the electronic rearview mirror for commercial vehicles physically blocks the image displayed on the screen from forming a reflective virtual image on the driver's side side window and the passenger side windshield, thereby improving the driver's direct vision when driving at night, reducing the possibility of driver error, improving driving safety, and having low manufacturing and usage costs. When the monitor component of the electronic rearview mirror is installed on the driver's side of the commercial vehicle, the baffle for the electronic rearview mirror for commercial vehicles is located between the display screen and the side window; when the monitor component is installed on the passenger side of the commercial vehicle, the baffle for the electronic rearview mirror for commercial vehicles is located between the display screen and the windshield. Simultaneously, the end of the baffle protrudes 50mm-100mm above the screen surface of the display screen to minimize the formation of reflective virtual images on the glass. Compared to other existing solutions, such as using a brightness sensor on the display to collect brightness and then using software algorithms to reduce the display brightness, this method can also lead to driver misjudgment or misoperation, thus causing driving safety issues.

[0018] 2. The baffle and electronic rearview mirror for commercial vehicles provided by this utility model have shapes of baffle and conformal plate designed according to the edge shape of the display screen and display screen support on which they are installed, i.e. conformal design, and the setting of limiting plate, which play a role in quick positioning and limiting during the process of installing the baffle for commercial vehicle electronic rearview mirror on the display screen support, thereby improving installation efficiency.

[0019] 3. The baffle and electronic rearview mirror for commercial vehicles provided by this utility model, by providing stiffening ribs and / or second protrusions on both sides of the first protrusion, prevents deformation of the conformal plate after it is connected to the display screen bracket through the connector and connecting hole, thereby improving the structural strength at that point. The first protrusion also increases the thickness of the connector's pressing surface, preventing excessive installation torque from causing the conformal plate to crack at that point.

[0034]

Example 1

[0035] Example 1 discloses a specific implementation of an electronic rearview mirror, including a monitor assembly and a camera (not shown in the figure), wherein, as Figure 3 As shown, the monitor assembly includes a baffle for a commercial vehicle electronic rearview mirror, a display screen 10, and a display screen bracket 11. A camera is communicatively connected to the display screen 10, thereby displaying the image captured by the camera on the display screen 10 to show the driver the rear and side views of the vehicle. In this embodiment, the display screen 10 is a single piece, and the monitor assembly is installed on the driver's side inside the commercial vehicle. In this case, the baffle for the commercial vehicle electronic rearview mirror is located between the display screen 10 and the side window glass.

[0036] like Figures 1-3 As shown, the baffle is connected to the display screen support 11, and the bottom of the display screen 10 is mounted on the display screen support 11. The baffle includes a shielding plate 1, a conformal plate 2, and a limiting plate 3 connected in sequence, and the shielding plate 1, conformal plate 2, and limiting plate 3 are all made of high-strength plastic with a thickness of 8mm. The conformal plate 2 conforms to the contours of the display screen 10 and the display screen support 11 at the corresponding locations, that is, the conformal plate 2 is set according to the contours of the display screen 10 and the display screen support 11. The limiting plate 3 is attached to the end face of the display screen support 11 away from the display screen 10. The conformal design of the conformal plate 2 and the setting of the limiting plate 3 play a role in quick positioning and limiting during the installation of the baffle for the electronic rearview mirror of commercial vehicles on the display screen support 11, thereby improving installation efficiency.

[0037] Even better, the shield 1 is also designed to conform to the corresponding side of the display screen 10, which can also play a role in quick positioning and limiting during installation.

[0038] like Figures 1-3As shown, the baffle is connected to the display screen support 11 via a conformal plate 2. Specifically, the conformal plate 2 has two connecting holes 5, which are arranged along the extension direction of the corresponding side of the display screen support 11. The baffle is detachably connected to the display screen support 11 via the connecting holes 5 and screws 7. In other embodiments, the screws 7 can be replaced with other detachable connectors, such as clips, bolt assemblies, etc., which will not be described in detail here.

[0039] To ensure that the baffle can minimize the reflection of virtual images of the display screen 10 on the side window glass, the vertical distance A from the end of the baffle 1 away from the conformal plate 2 to the screen surface of the display screen 10 (see...) Figure 3 The diameter is 75mm.

[0040] This baffle for commercial vehicle electronic rearview mirrors improves the driver's direct field of vision at night, reduces the possibility of driver error, and enhances driving safety, while also having lower manufacturing and usage costs. In contrast, other existing solutions, such as those that use a brightness sensor on the display to collect brightness and then employ software algorithms to reduce the display's brightness, can also lead to driver misjudgment or misoperation, thus causing driving safety issues.

[0041] In other embodiments, the thickness of the shielding plate 1, the conformal plate 2, and the limiting plate 3 can be any value between 5mm and 10mm, such as 5mm, 6mm, etc., designed according to actual structural strength requirements; the vertical distance from the end of the shielding plate 1 away from the conformal plate 2 to the screen surface of the display screen 10 can also be any value between 50mm and 100mm, designed according to the actual situation such as the size of the display screen 10, the installation angle and position of the display screen 10; the number of connecting holes 5 is not limited to this example, and can also be one, three or even more, designed according to the actual situation, which will not be elaborated here.

[0042] More preferably, the baffle 1 is located on the side of the display screen 10 and extends along the corresponding side of the display screen 10 and covers the corresponding side of the display screen 10, thereby making the baffle completely avoid the reflection of the display screen 10 on the side window glass.

[0043]

Example 2

[0044] like Figures 1-3As shown, Embodiment 2 discloses another specific implementation of a baffle for a commercial vehicle electronic rearview mirror. Embodiment 2 has a basically the same baffle structure as Embodiment 1 for a commercial vehicle electronic rearview mirror, except that in Embodiment 2, the conformal plate 2 protrudes in a quadrilateral shape from the position corresponding to the connecting hole 5, moving away from the display screen support 11. The inner surface of the first protrusion 4 has a first preset distance from the display screen support 11, and the connecting hole 5 is located on the first protrusion 4. This first protrusion 4 can increase the thickness of the screw 7 pressing surface, preventing excessive screw 7 installation torque from causing the conformal plate 2 to crack at this location.

[0045] The first preset distance in this embodiment can be designed according to actual conditions, such as 0.5mm, 0.8mm, 1mm, etc., and is not limited here.

[0046] More preferably, stiffening ribs 6 are provided on both sides of the two first protrusions 4. The stiffening ribs 6 located on both sides of the same first protrusion 4 form a preset angle, which can be designed according to the structural strength requirements and is not limited here. The stiffening ribs 6 prevent the conformal plate 2 from deforming after it is connected to the display screen support 11 by screws 7 and connecting holes 5, thereby improving the structural strength at this point.

[0047] like Figures 1-2 As shown, in order to prevent the stiffening rib 6 from interfering with other parts inside the vehicle, the edge of the stiffening rib 6 away from the baffle is arc-shaped.

[0048]

Example 3

[0049] Example 3 discloses another specific implementation of a baffle for a commercial vehicle electronic rearview mirror. The baffle for the commercial vehicle electronic rearview mirror in this example is applicable to the case where there are two display screens 10. The long sides of the two display screens 10 are placed perpendicular to each other, and the monitor component of the electronic rearview mirror is installed on the passenger side inside the vehicle. The baffle of the commercial vehicle electronic rearview mirror is located between the display screen 10 and the windshield.

[0050] like Figures 4-6 As shown, the baffle for the electronic rearview mirror of a commercial vehicle in Embodiment 3 has a basically the same structure as the baffle for the electronic rearview mirror of a commercial vehicle in Embodiment 2, and the vertical distance A from the end of the baffle 1 away from the conformal plate 2 to the screen surface of the display screen 10 (see...) Figure 6 The diameter is also 75mm, but the difference is that it also includes a second protrusion 8, and there are three connecting holes 5, and the two connecting holes 5 are not provided with stiffening ribs 6 on both sides of the first protrusion 4.

[0051] Specifically, such as Figures 4-6As shown, in this embodiment, there are two second protrusions 8. The second protrusions 8 are formed by the simultaneous protrusion of the baffle plate 1 and the conformal plate 2 towards the direction away from the display screen support 11. The inner surface of the second protrusion 8 has a second preset distance from the display screen support 11, which is greater than a first preset distance. The first and second second protrusions 8 are respectively located on both sides of the connecting hole 5 in the middle, meaning that a second protrusion 8 is provided on both sides of the first protrusion 4 in the middle. The second protrusion 8 is more prominent than the first protrusion 4, and its concave-convex shape forms a reinforcing wall effect on both sides of the first protrusion 4, thereby improving the structural strength and preventing baffle deformation. Even if the third first protrusion 4 only has a second protrusion 8 on one side, it can still provide a certain degree of structural strength enhancement.

[0052] Of course, in other embodiments, a second protrusion 8 may be provided on one or both sides of a first protrusion 4 to enhance structural strength.

[0053] Furthermore, such as Figure 4 As shown, in order to reduce stress concentration at the connection between the second protrusion 8 and the baffle plate 1, which could easily lead to breakage, at least a portion of the edge of the second protrusion 8 is connected to the baffle plate 1 via an inclined surface 9, that is, the second protrusion 8 is quadrilateral, and the upper edge of the second protrusion 8 is connected to the baffle plate 1 via an inclined surface 9.

[0054] In other embodiments, the vertical distance from the end of the baffle plate 1 away from the conformal plate 2 to the screen surface of the display screen 10 can also be any value between 50mm and 100mm, which can be designed according to the actual situation such as the size of the display screen 10, the installation angle and position of the display screen 10, etc., and will not be described in detail here.

[0055] It should be noted that when both the driver's side and the passenger side of the vehicle are equipped with monitor components, the baffles for the electronic rearview mirror of commercial vehicles in the above embodiments can be arranged and used simultaneously. That is, the driver's side uses the baffles for the electronic rearview mirror of commercial vehicles in Embodiments 1 and 2, and the passenger side uses the baffles for the electronic rearview mirror of commercial vehicles in Embodiment 3.
