[0031] The technical solutions provided by the embodiments of the present invention are described below with reference to the accompanying drawings.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this application provides an image acquisition device 10, which is installed on the windshield of a vehicle. The image acquisition device 10 includes a mounting bracket 100 and an image acquisition mechanism 200. The mounting bracket 100 includes a base 110, a docking frame 120, and a mounting channel 130. The base 110 has a first mounting side 111 and a second mounting side 112 disposed opposite to each other. The first mounting side 111 is used to fit against the windshield, and the docking frame 120 is disposed on the second mounting side 112. The mounting channel 130 passes through the base 110 and the docking frame 120. In a specific configuration, the mounting bracket 100 is preferably made of high-strength, lightweight engineering plastic material to ensure structural strength while reducing costs.

[0033] The image acquisition mechanism 200 is installed in the installation channel 130. The image acquisition mechanism 200 includes a camera module for acquiring the driving conditions inside and outside the vehicle and an image recognition module for acquiring the driver's driving conditions.

[0034] The aforementioned image acquisition device 10, by setting the first mounting side 111 of the base 110 in the mounting bracket 100 to fit against the windshield, provides a stable mounting foundation and reduces the need for additional fasteners; by setting the docking frame 120 on the second mounting side 112, and the mounting channel 130 passing through the base 110 and the docking frame 120, the image acquisition mechanism 200 is internally installed, which not only protects the image acquisition mechanism 200, but also integrates and fixes the image acquisition mechanism 200, including the camera module and the image recognition module, to the windshield through the mounting bracket 100, eliminating the space occupation of scattered installations, simplifying the installation process and saving vehicle interior space, while also reducing wiring complexity and eliminating safety hazards.

[0035] In order to protect the mounting bracket 100 and the image acquisition mechanism 200 without affecting the operation of the image acquisition mechanism 200, the image acquisition device 10 also includes a protective cover 300 disposed on the side of the mounting bracket 100 away from the windshield. The protective cover 300 covers the mounting bracket 100 and the image acquisition mechanism 200, and the protective cover 300 has an expansion groove 310 and a clearance through hole 320 disposed on the groove wall of the expansion groove 310. The clearance through hole 320 is connected to the mounting channel 130. The clearance through hole 320 allows the image acquisition mechanism 200 to acquire images, and the expansion groove 310 facilitates the image acquisition mechanism 200 to form an acquisition field of view area 330 through the clearance through hole 320.

[0036] In a specific configuration, the image acquisition mechanism 200 includes an acquisition mounting base 210 and an image acquisition device disposed within the acquisition mounting base 210. The image acquisition device includes a camera module and an image recognition module disposed within the camera module. Specifically, the acquisition mounting base 210 has a contoured cavity for mounting the image acquisition device. The acquisition mounting base 210 is mounted in the mounting channel 130, avoiding potential mechanical damage when directly mounting the image acquisition device in the mounting channel 130, thereby simplifying the installation process and improving structural stability. It should also be noted that both the camera module and the image recognition module are mature technologies and will not be elaborated upon here.

[0037] Combination Figure 4 As shown, to facilitate the formation of an installation channel 130 for installing the acquisition mounting base 210, specifically, the base 110 has a first through hole 113 extending through its own thickness along its thickness direction. The docking frame 120 includes a top plate 121 and a side wall 122 connected to the top plate 121. The top plate 121 and the side wall 122 form a receiving space 123 communicating with the first through hole 113. In a specific configuration, the side wall 122 includes side plates 1221 disposed on opposite sides of the top plate 121, and the receiving space 123 is formed between the top plate 121 and the two side plates 1221, directly opposite the first through hole 113. The top plate 121 has a second through hole 1211 extending through itself along its own thickness direction. The first through hole 113, the receiving space 123, and the second through hole 1211 form the installation channel 130. During installation, the mounting base 210 passes through the first through hole 113 and is fixed to the receiving space 123 and the second through hole 1211.

[0038] Combination Figure 5 and Figure 6To facilitate the installation of the acquisition mounting base 210 and the docking seat through the mounting channel 130, more specifically, the acquisition mounting base 210 includes a main mounting shell 211 and a first snap-fit ​​protrusion 212 disposed on the outer side of the main mounting shell 211; the side wall 122 has a first snap-fit ​​hole 1222 communicating with the receiving space 123, the first snap-fit ​​hole 1222 is disposed near the second through hole 1211, and the first snap-fit ​​hole 1222 is adapted to the first snap-fit ​​protrusion 212. In a specific configuration, there are multiple first snap-fit ​​protrusions 212, preferably two in this application, the two first snap-fit ​​protrusions 212 are symmetrically disposed on the two side walls 122 of the main mounting shell 211, and the two side plates 1221 in the side wall 122 respectively have first snap-fit ​​holes 1222 adapted to the two first snap-fit ​​protrusions 212.

[0039] To facilitate the first snap-fit ​​protrusion 212 reaching the first snap-fit ​​hole 1222, the sidewall 122 is further provided with a guide channel 1223 connected to the first through hole 113 and the receiving space 123. The guide channel 1223 is located at the bottom of the first snap-fit ​​hole 1222, and is spaced apart from and not connected to the first snap-fit ​​hole 1222. With this arrangement, the first snap-fit ​​protrusion 212 passes through the first through hole 113 into the guide channel 1223, reaches directly below the first snap-fit ​​hole 1222 via the guide channel 1223, and then continues to move upwards through the inner wall of the receiving space 123 to reach the first snap-fit ​​hole 1222. In specific configurations, the number of guide channels 1223 is the same as the number of first snap-fit ​​protrusions 212.

[0040] To facilitate the first snap-fit ​​protrusion 212's entry into the first snap-fit ​​hole 1222 via the guide channel 1223 and the inner wall of the receiving space 123, the first snap-fit ​​protrusion 212 further includes an abutment portion 2121 and a plurality of guide portions 2122 spaced apart from the abutment portion 2121. In specific configuration, the number of guide portions 2122 is preferably two, but not limited to two; specifically, it can be three, four, or more. To more easily achieve the guiding function of the guide portions 2122, the guide portions 2122 gradually narrow towards the main mounting shell 211 along the direction away from the abutment portion 2121. Through the above configuration, the first snap-fit ​​protrusion 212 can naturally transition to the guide channel 1223 along the inner wall of the receiving space 123.

[0041] To enhance the connection between the acquisition mounting base 210 and the docking seat, the acquisition mounting base 210 further includes a second snap-fit ​​protrusion 213 disposed on the outer side of the main mounting shell 211. The side wall 122 also has a guide snap-fit ​​hole 1224 connected to the first through hole 113 and the receiving space 123, the guide snap-fit ​​hole 1224 being adapted to the second snap-fit ​​protrusion 213. In specific configurations, the number of second snap-fit ​​protrusions 213 is multiple; preferably, two are used. The two second snap-fit ​​protrusions 213 are symmetrically disposed on both side walls 122 of the main mounting shell 211, and the two side plates 1221 in the side wall 122 each have a guide snap-fit ​​hole 1224 adapted to the two second snap-fit ​​protrusions 213.

[0042] To ensure that the second latching protrusion 213 and the first latching protrusion 212 can slide smoothly into the corresponding guide latching hole 1224 and guide channel 1223 simultaneously, the guide latching hole 1224 and guide channel 1223 are spaced apart and parallel. In a specific configuration, the outer periphery of the guide channel 1223 and the guide latching hole 1224 are respectively provided with a first reinforcing rib 1225 and a second reinforcing rib 1226. The first reinforcing rib 1225 and the second reinforcing rib 1226 are respectively arranged around the outer contour shape of the guide channel 1223 and the guide latching hole 1224. The shape of the guide channel 1223 and the guide latching hole 1224 can be any geometric shape, and no further limitations are imposed here.

[0043] To ensure the connection stability between the acquisition mounting base 210 and the docking seat, the acquisition mounting base 210 further includes a camera extension shell 214 disposed at one end of the main mounting shell 211. The camera extension shell 214 has a third snap-fit ​​protrusion 215, and the inner wall of the second through hole 1211 has a snap-fit ​​groove 1212 adapted to the third snap-fit ​​protrusion 215. When the second through hole 1211 allows the camera extension shell 214 to pass through, the third snap-fit ​​protrusion 215 on the camera extension shell 214 is adapted to the snap-fit ​​groove 1212. In a specific configuration, a third reinforcing rib 1213 is provided on the outer contour formed by the second through hole 1211 and the snap-fit ​​groove 1212, increasing the contact area between the third snap-fit ​​protrusion 215 and the snap-fit ​​groove 1212, thereby increasing the connection stability between the two.

[0044] To prevent noise and loosening after the acquisition mounting base 210 is installed on the docking frame 120, the acquisition mounting base 210 further includes an elastic buffer pad 220 disposed in the receiving space 123. The elastic buffer pad 220 has a contoured groove 221 adapted to the camera extension shell 214 and the third snap-fit ​​protrusion 215, and the contoured groove 221 is directly opposite the second through hole 1211. In specific installation, the elastic buffer pad 220 is preferably foam to optimize the fitting tolerance between the camera extension shell 214 and the third snap-fit ​​protrusion 215 and the corresponding second through hole 1211 and snap-fit ​​groove 1212.

[0045] To facilitate user monitoring of vehicle status, the image acquisition unit specifically includes a control module that communicates with the camera module and image recognition module. The control module processes and transmits received vehicle and interior / exterior driving data signals and driver driving status data signals to the central control unit and / or mobile terminal device. In a specific configuration, the camera module is a high-definition dual-lens camera with wide-angle shooting capabilities, enabling panoramic in-vehicle shooting for in-vehicle photography and driving recording. The image recognition module includes an infrared sensor and an image recognition chip that converts the light signals from the infrared sensor into electrical signals for subsequent communication with the central control unit and / or mobile terminal device.

[0046] Infrared sensors are used to detect the driver's condition, monitoring facial expressions, eye movements, and body posture in real time to determine if the driver is fatigued or inattentive. This system allows for timely detection of abnormal driver conditions, providing early warnings, effectively preventing traffic accidents, and improving driving safety.

[0047] This application also provides a windshield assembly, which includes the image acquisition device as described in any of the above embodiments.

[0048] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
