[0035] Reference Figure 1 , Figure 2 and Figure 3 The camera device provided by the embodiment of the utility model includes a front shell 10, a rear cover 20, a first circuit board 30 and a lens assembly 40. The front shell 10 has a receiving cavity 11, and the first circuit board 30 is arranged in the receiving cavity 11 and connected to the front shell 10. The rear end of the receiving cavity 11 has an opening, and the rear cover 20 is arranged at the opening and connected to the front shell 10 to close the opening of the front shell 10 and protect the components in the receiving cavity 11. The front shell 10 has a lens mounting hole 121 that penetrates. The lens assembly 40 is penetrated in the lens mounting hole 121 so that light can enter the lens assembly 40. The lens assembly 40 is fixedly connected to the side of the first circuit board 30 opposite to the lens mounting hole 121. The light entering the lens assembly 40 is converted into an electrical signal by the sensor. The first circuit board 30 can also further process the electrical signal converted by the sensor to realize image acquisition.

[0036] The front shell 10 has a front wall 12 opposite to the opening, a lens mounting hole 121 passes through the front wall 12, the first circuit board 30 is arranged opposite to the front wall 12, and the base of the lens assembly 40 is fixed to the side of the first circuit board 30 opposite to the front wall 12, and the other end passes through the lens mounting hole 121. In an optional embodiment, the outer surface of the front wall 12 (i.e., the side surface opposite to the accommodating cavity 11) has a protruding side wall 127, and the side wall 127 surrounds the outer periphery of the lens mounting hole 121, so that the position of the lens assembly 40 can be appropriately extended beyond the outer surface of the front wall 12, which is conducive to reducing obstruction and expanding the viewing angle of image acquisition. The camera device also includes a protective lens 90 made of resin or other light-transmitting materials. The protective lens 90 is arranged at one end of the lens mounting hole 121 away from the first circuit board 30 and is arranged opposite to the lens assembly 40, which is used to protect the lens assembly 40. Optionally, in the area surrounded by the side wall 127 , a fixing groove 128 corresponding to the shape of the protective lens 90 is provided at one end of the lens mounting hole 121 away from the first circuit board 30 , and the protective lens 90 is fixed in the fixing groove 128 .

[0037] Reference Figure 4In this embodiment, the lens assembly 40 is disposed at the corner of the first circuit board 30. The end surface of the first circuit board 30 can be approximately rectangular, rhombus, circular or other shapes, which can be selected according to the application scenario of the camera device and the shape of the front shell 10. The lens assembly 40 is disposed near the edge or corner of the first circuit board 30. For example, referring to Figure 4 In this embodiment, the end face of one side of the first circuit board 30 where the lens assembly 40 is arranged is approximately rectangular, and the rectangular first circuit board 30 has four corners, and the lens assembly 40 is arranged at one of the corners of the first circuit board 30. Compared with arranging the lens assembly 40 at the middle position of the first circuit board 30, this arrangement of arranging the lens assembly 40 at the corner of the first circuit board 30 is conducive to ensuring the width and continuity of the remaining part of the first circuit board 30 except the position where the lens assembly 40 is arranged, facilitating the arrangement of electrical components and connecting wires on the first circuit board 30, and is conducive to reducing the overall size of the first circuit board 30, thereby facilitating the miniaturization of the camera device.

[0038] Reference Figure 3 and Figure 7 The front housing 10 has a lens mounting column 126, which is convexly arranged on the inner surface of the front wall 12, and the lens mounting hole 121 passes through the lens mounting column 126. The length of the lens mounting column 126 can be set accordingly according to the length of the lens assembly 40 and the position of the first circuit board 30. Preferably, the end surface of the lens mounting column 126 does not contact the first circuit board 30 to avoid mutual compression and damage to the first circuit board 30. The setting of the lens mounting column 126 can make the length of the lens mounting hole 121 longer, which can better realize the positioning and support of the lens assembly 40.

[0039] In one embodiment, the front shell 10 is made of metal material, which is conducive to ensuring the structural strength of the front shell 10 and providing better protection for the components in the accommodating cavity 11. The rear cover 20 can be made of plastic, which is conducive to reducing manufacturing costs.

[0040] In some embodiments, Figure 2 and Figure 3As shown, the camera device also includes a second circuit board 50, and the first circuit board 30 is electrically connected to the second circuit board 50. Since the lens assembly 40 has a certain length, there is a certain space between the first circuit board 30 and the inner surface of the front wall 12, and the second circuit board 50 can be arranged between the first circuit board 30 and the front wall 12 and connected to the front shell 10, thereby making full use of the space of the accommodating cavity 11, which is conducive to the miniaturization of the camera device. Preferably, the second circuit board 50 is arranged substantially parallel to the first circuit board 30 and has a certain interval, which can prevent the installation of the first circuit board 30 and the second circuit board 50 from interfering, and can make the overall structure of the camera more compact. The size of the second circuit board 50 can be smaller than that of the first circuit board 30, so as to be arranged in the space between the first circuit board 30 and the front wall 12. Optionally, the second circuit board 50 has an avoidance structure 51 for avoiding the lens assembly 40, for example, referring to Figure 2 , Figure 6 and Figure 7 The second circuit board 50 is provided with a notch as an avoidance structure 51 corresponding to the position of the lens assembly 40 .

[0041] Reference Figure 1 The camera device further includes a wire harness 60. The side wall of the front shell 10 is provided with a wire harness through hole 13. One end of the wire harness 60 is provided in the accommodating cavity 11 and is electrically connected to the first circuit board 30 or the second circuit board 50. The other end of the wire harness 60 passes through the front shell 10 through the wire harness through hole 13. A sealing structure may also be provided in the wire harness through hole 13 to prevent liquid or dust from entering the accommodating cavity 11 through the gap between the wire harness through hole 13 and the wire harness 60.

[0042] Reference Figure 3 and Figure 7 , the first circuit board 30 and the second circuit board 50 can be connected to the front shell 10 by fasteners to be fixed in the accommodating cavity 11. In one embodiment, the inner surface of the front wall 12 is provided with a first connecting column 122 and a second connecting column 123 protruding in the direction close to the opening of the accommodating cavity 11, the first connecting column 122 and the second connecting column 123 are spaced apart, and the length of the first connecting column 122 is greater than the length of the second connecting column 123. The length of the first connecting column 122 and the length of the second connecting column 123 respectively refer to the distance from the end face of the first connecting column 122 to the front wall 12 and the distance from the end face of the second connecting column 123 to the front wall 12. The first connecting column 122 is used to connect to the first circuit board 30, and the second connecting column 123 is used to connect to the second circuit board 50. The camera device includes a first threaded fastener 81 and a second threaded fastener 82, and the first connecting column 122 and the second connecting column 123 respectively have threaded holes. Referring to Figure 3 and Figure 5 , the first circuit board 30 is fixed to the first connecting column 122 by the first threaded fastener 81; Figure 3 and Figure 7 , the second circuit board 50 is fixed to the second connection column 123 by the second threaded fastener 82. The arrangement of the first connection column 122 and the second connection column 123 can provide a corresponding structure for the installation of the first circuit board 30 and the second circuit board 50 in the accommodating cavity 11, and can play a role in ensuring the relative positions of the first circuit board 30 and the second circuit board 50. The first threaded fastener 81 and the second threaded fastener 82 can be selected from screws, bolts, studs or other threaded fasteners, respectively, and the first threaded fastener 81 and the second threaded fastener 82 can be the same or different.

[0043] In one embodiment, referring to Figure 7 The inner surface of the front wall 12 is provided with a first positioning column 124 and a second positioning column 125, and the first positioning column 124, the first connecting column 122, the second positioning column 125 and the second connecting column 123 are arranged at intervals. Figure 4 and Figure 5 As shown, the first circuit board 30 has a first positioning hole 31, and the first positioning column 124 is inserted into the first positioning hole 31 to realize the positioning of the first circuit board 30. Preferably, the length of the first positioning column 124 is greater than the length of the first connecting column 122, or in other words, the distance between the end of the first positioning column 124 and the front wall 12 is greater than the distance between the end surface of the first connecting column 122 and the front wall 12. When the first circuit board 30 is installed in the accommodating cavity 11, if the first positioning hole 31 and the first positioning column 124 are not aligned, the first positioning column 124 will push against the first circuit board 30, resulting in the first circuit board 30 being unable to contact the first connecting column 122, thereby playing a foolproof role and avoiding the first circuit board 30 from being installed in the wrong direction. Figure 6 and Figure 7 As shown, the second circuit board 50 has a second positioning hole 52, and the second positioning column 125 is passed through the second positioning hole 52 to realize the positioning of the second circuit board 50. Preferably, the length of the second positioning column 125 is greater than the length of the second connecting column 123, or in other words, the distance between the end of the second positioning column 125 and the front wall 12 is greater than the distance between the end surface of the second connecting column 123 and the front wall 12. When the second circuit board 50 is installed in the accommodating cavity 11, if the second positioning hole 52 and the second positioning column 125 are not aligned, the second positioning column 125 will abut against the second circuit board 50, resulting in the second circuit board 50 being unable to contact the second connecting column 123, thereby playing a foolproof role and avoiding the second circuit board 50 from being installed in the wrong direction.

[0044] Reference Figure 2 and Figure 3The camera device further includes a sealing ring 70 for sealing the gap between the rear cover 20 and the front shell 10. In this embodiment, the rear end of the front shell 10 has a sealing flange 14 corresponding to the sealing groove 21, and the sealing flange 14 surrounds the outside of the opening. The side of the rear cover 20 opposite to the front shell 10 has a sealing groove 21 corresponding to the position of the sealing flange 14. When the rear cover 20 is assembled with the front shell 10, the sealing ring 70 is photographed in the sealing groove 21, and the sealing groove 21 is aligned with the sealing flange 14, and then the rear cover 20 is fixedly connected with the front shell 10, and the sealing flange 14 presses the sealing ring 70 into the sealing groove 21 to achieve sealing. The sealing flange 14 is a continuous ring-like structure. The arrangement of the sealing flange 14 and the sealing groove 21 makes the path of the joint between the rear cover 20 and the front shell 10 more tortuous, which is conducive to better achieving the sealing effect.

[0045] The camera device includes a third threaded fastener 83, and the front shell 10 and the rear shell can be detachably fixed by the third threaded fastener 83. The front shell 10 has a first fixing hole 15, and the rear cover 20 has a second fixing hole 22. The first fixing hole 15 is a threaded hole. The third threaded fastener 83 passes through the second fixing hole 22 and is connected to the first fixing hole 15 to connect the rear cover 20 and the front shell 10. Optionally, the first fixing hole 15 is provided on the outside of the sealing flange 14, and the second fixing hole 22 is provided on the outside of the sealing groove 21, which is conducive to better sealing between the front shell 10 and the rear cover 20.

[0046] Reference Figure 8 , the side of the rear cover 20 away from the front shell 10 has a plurality of mounting holes 23 for fixing the camera device to the vehicle body 100, and the mounting holes 23 are threaded blind holes. The camera device can be fixed to the vehicle body 100 by passing screws through the corresponding holes on the camera mounting structure of the vehicle body 100 and the mounting holes 23 on the rear cover 20. The mounting holes 23 are blind holes to prevent liquid from entering the accommodating cavity 11 from the mounting holes 23, which is conducive to achieving a better sealing effect. It can be understood that the above only provides a feasible installation method for the camera device, and other installation methods can also be used to install the camera device on the vehicle according to the specific needs of installing the camera device on the vehicle. The embodiments of the utility model do not impose too many restrictions on this.

[0048] In this embodiment, the camera device is disposed at the front of the vehicle body 100 and is configured to collect images in the direction of the vehicle's travel. Fig. 9 , the camera mounting structure is a basket 101, a handlebar 102 or a frame 103. After the camera device is fixed on the camera mounting structure, the lens faces the forward direction of the vehicle. After the camera device collects an image of the forward direction of the vehicle, the image can be used to determine whether there are violations of traffic regulations or other dangerous behaviors such as running a red light, driving in the wrong direction, and deviating from the lane during the riding of the vehicle. By applying the camera device in at least some of the embodiments above, a necessary detection structure can be provided for the detection of the driving behavior of the vehicle, and the camera device has a compact structure, high structural strength and durability, and is suitable for use in shared vehicles.
