[0002] Two-wheeled vehicles have become an important part of people's travel due to their flexibility, convenience and low pollution, and have also alleviated traffic pressure to a certain extent. Among them, shared two-wheeled vehicles provide people with a convenient way to travel and are popular with people. However, while shared two-wheeled vehicles are flexible to use, they also bring difficulties in management. Some users park their vehicles at random after using the shared two-wheeled vehicles, which easily hinders road order and also brings difficulties to the maintenance and management of shared two-wheeled vehicles. At present, a solution to regulate the parking order of shared two-wheeled vehicles is to use the camera on the vehicle to shoot the surrounding environment of the vehicle for comparison when the user parks to determine whether the vehicle is parked in an area where parking is allowed.

[0046] The present invention provides an image acquisition device 1, referring to Figures 1 to 3 The image acquisition device 1 includes a housing 10, a circuit board assembly 20 and a lens assembly 30 disposed in the housing 10. The housing 10 includes a front housing 11 and a rear housing 12 connected to each other, and the front housing 11 and the rear housing 12 are connected to form a cavity. The side of the front housing 11 opposite to the rear housing 12 has a first receiving groove 111 that is recessed in a direction away from the rear housing 12. The circuit board assembly 20 is disposed in the cavity of the housing 10 and is at least partially disposed in the first receiving groove 111. Figure 3 and Figure 7 The front shell 11 is provided with a through lens hole 112 at the bottom of the first accommodating groove 111. The circuit board assembly 20 includes a first circuit board 21. The first circuit board 21 is arranged opposite to the lens hole 112 with an interval and has a lens mounting area 211 opposite to the lens hole 112. The lens assembly 30 is installed in the lens mounting area 211 so that the lens assembly 30 can be aligned with the lens hole 112.

[0047] The lens mounting area 211 may be provided with an image sensor, and the lens assembly 30 includes a base 31 and a lens 32 provided on the base 31, and the base 31 is fixed to the lens mounting area 211, so that the image sensor is provided on the optical path of the lens 32. For example, the base 31 may be screwed to the first circuit board 21. The light entering the lens 32 is converted into an electrical signal by the image sensor, and the first circuit board 21 may further process the electrical signal converted by the sensor to realize image acquisition.

[0048] Figures 4 to 6 The structure of the circuit board assembly 20 is shown. Figures 2 to 6 In this embodiment, the circuit board assembly 20 may further include a second circuit board 22, which is spaced apart from the side of the first circuit board 21 close to the lens through hole 112, that is, the second circuit board 22 is disposed between the first circuit board 21 and the bottom of the first accommodating groove 111. The second circuit board 22 is provided with a lens avoidance hole 221, and the position of the lens avoidance hole 221 corresponds to the position of the lens installation area 211 of the first circuit board 21 and the lens through hole 112 of the front shell 11. The lens 32 can pass through the lens avoidance hole 221 and extend toward the lens through hole 112. This design is conducive to making the structure of the image acquisition device 1 more compact.

[0049] The second circuit board 22 is electrically connected to the first circuit board 21. In this embodiment, the circuit board assembly 20 further includes at least one first board-to-board connector 24, and the first circuit board 21 and the second circuit board 22 are electrically connected through the first board-to-board connector 24. Optionally, the first board-to-board connector 24 can be a corresponding pin header and a female header. One of the first circuit board 21 and the second circuit board 22 is provided with a pin header, and the other of the two is provided with a female header corresponding to the pin header at a corresponding position. The electrical connection between the first circuit board 21 and the second circuit board 22 can be achieved by plugging the pin header and the female header. At the same time, the first board-to-board connector 24 is also conducive to ensuring that there is an appropriate spacing between the first circuit board 21 and the second circuit board 22.

[0050] In this embodiment, the image acquisition device 1 further includes a first connecting member 40, which connects the first circuit board 21 and the front shell 11. The specific form of the first connecting member 40 can be selected according to the installation requirements of the circuit board assembly 20. Optionally, the first connecting member 40 can be a threaded fastener such as a screw, Figure 4 and Figure 6 The first circuit board 21 has a first fixing hole 212, and the front shell 11 is provided with a first threaded hole corresponding to the first connector 40. The first circuit board 21 can be fixed in the housing 10 by passing the first connector 40 through the first fixing hole 212 and then connecting with the first threaded hole. In addition, since the first circuit board 21 and the second circuit board 22 are electrically connected through the first board-to-board connector 24, the first board-to-board connector 24 can play a certain role in relative fixing between the first circuit board 21 and the second circuit board 22. When the first circuit board 21 is fixed in the housing 10 through the first connector 40, the second circuit board 22 can also be relatively fixed in the housing 10.

[0051] In this embodiment, refer to Figure 4 and Figure 6 , the shape of the second circuit board 22 is configured to avoid the first connector 40. For example, the second circuit board 22 can be set smaller to avoid the area where the first connector 40 is located; or, avoidance structures such as avoidance holes and avoidance grooves are set at the positions corresponding to the second circuit board 22 and the first connector 40 to avoid contact between the first connector 40 and the second circuit board 22. This arrangement can avoid the difficulty of assembly caused by the first connector 40 connecting the first circuit board 21, the second circuit board 22 and the housing 10 at the same time, and the situation that the first circuit board 21 or the second circuit board 22 is easily deformed or damaged due to stress.

[0052] Figure 7 is a schematic structural diagram of the front housing 11 viewed from the open side of the first receiving groove 111. Figure 7The bottom of the first accommodating groove 111 has a contoured groove 1111 matching the shape of the second circuit board 22, and the lens through hole 112 is opened in the contoured groove 1111.

By selecting a nut of appropriate length, a predetermined distance between the second circuit board 22 and the third circuit board 23 can be maintained.

[0058] Optionally, the image acquisition device 1 further includes an antenna 100, which may be a short-range communication antenna or a mobile communication antenna, and may be selected according to the needs of the application scenario. The image acquisition device 1 may realize wireless communication with other external devices through the antenna 100. In one embodiment, referring to Figure 3 The antenna 100 is arranged on the inner wall of the rear shell 12, so that the space in the shell 10 can be fully utilized. The specific arrangement position of the antenna 100 on the inner wall of the rear shell 12 can be selected according to the shape of the antenna 100, the shape of the rear shell 12, the radiation direction required by the antenna 100, and other specific conditions. Figure 3 and Fig. 9 As shown, the third circuit board 23 has a feeding pin 231 , which is opposite to the antenna 100 . When the circuit board assembly 20 is installed in the housing 10 , the feeding pin 231 contacts the antenna 100 to feed the antenna 100 .

When the circuit board assembly 20 is installed in the housing 10, the first circuit board 21 and the second circuit board 22 can be plugged in through the first board-to-board connector 24, and then the first circuit board 21 and the second circuit board 22 can be placed in the first receiving groove 111 of the front shell 11 and connected to the front shell 11 through the first connector 40, and then the third circuit board 23 and the first circuit board 21 can be connected through the second connector 50 to complete the connection between the circuit board assembly 20 and the front shell 11 (refer to Fig. 9 ), and finally, the rear shell 12 is buckled onto the outside of the third circuit board 23 and connected to the front shell 11. This arrangement can facilitate the assembly of the image acquisition device 1 and is conducive to the miniaturization of the image acquisition device 1.

[0060] In this embodiment, the rear shell 12 includes a receiving portion 122 and a mounting wing 123. The second receiving groove 121 is provided in the receiving portion 122 and the receiving portion 122 bulges in a direction away from the front shell 11.

[0061] A sealing structure is provided at the connection between the front shell 11 and the rear shell 12 to achieve waterproofing of the image acquisition device 1. Figure 3 and Fig.10 The rear housing 12 has a sealing groove 124, and the sealing groove 124 surrounds the outer circumference of the second receiving groove 121. Figure 3 , Figure 7 and Fig. 9 The front shell 11 has a sealing flange 113 corresponding to the sealing groove 124, and the image acquisition device 1 also includes a sealing ring 60. The sealing flange 113 presses the sealing ring 60 into the sealing groove 124 to achieve sealing between the front shell 11 and the rear shell 12. Since the image acquisition device 1 can be used to acquire images of the ground, when the image acquisition device 1 is used, the lens 32 faces downward and the rear shell 12 is located above the front shell 11. The design of this sealing structure can better prevent liquid from penetrating into the housing 10 from the connection between the front shell 11 and the rear shell 12.

[0062] Furthermore, in one embodiment, the inner sidewall of the sealing groove 124 at least partially protrudes from the outer sidewall of the sealing groove 124, wherein the inner sidewall of the sealing groove 124 is the sidewall close to the second receiving groove 121, and the outer sidewall of the sealing groove 124 is the sidewall away from the second receiving groove 121. Fig.10 As shown, a side wall 125 is formed between the inner side wall of the sealing groove 124 and the second containing groove 121, and a first positioning structure 1251 is disposed on the side wall 125.
