The SIM card on connector 300 can be used to electrically connect to the controller for communication.

[0038] Based on the above configuration, the image acquisition device 10 of this application embodiment further includes a cover 200, which is disposed at the mounting port 110 and is detachably connected to the housing 100. Thus, the cover 200 can be installed on the housing 100 to close the mounting port 110, thereby protecting the memory card, connector 300, controller, camera module, etc., inside the accommodating cavity 120; the cover 200 can also be removed from the housing 100 to open the mounting port 110, allowing the memory card to enter the accommodating cavity 120 through the mounting port 110 and be installed on the connector 300.

[0039] The cover 200 includes a cover plate 210 and a column 220. The column 220 is disposed on one side of the cover plate 210, and one end of the column 220 is connected to the cover plate 210. When the cover 200 is installed on the housing 100, the column 220 passes through the mounting opening 110 and faces the receiving cavity 120. The cover plate 210 covers the outside of the mounting opening 110 and is exposed in the mounting opening 110.

[0040] The column 220 can be cylindrical or approximately cylindrical; the mounting opening 110 can be circular. When the column 220 is inserted into the mounting opening 110, the centerline of the column 220 is parallel to the centerline of the mounting opening 110, and the cross-section of the mounting opening 110 can also be circular along a direction perpendicular to the centerline of the column 220. This arrangement facilitates the insertion of the column 220 into the mounting opening 110 and allows the column 220 to rotate within the mounting opening 110, with the axis of rotation of the column 220 parallel to its centerline.

[0041] The column 220 is detachably connected to the housing 100, so that the cover 200 is detachably connected to the housing 100. For example, the mounting port 110 includes a mounting port wall 111, and the sidewall of the column 220 can be detachably connected to the mounting port wall 111.

[0042] In one optional embodiment, the sidewall of the column 220 is threadedly connected to the mounting opening wall 111. For example, the sidewall of the column 220 is provided with an external thread, and the mounting opening wall 111 is provided with an internal thread. The internal thread and the external thread mate to thread the sidewall of the column 220 and the mounting opening wall 111.

[0043] In another alternative embodiment, the sidewall of the column 220 is connected to the mounting port wall 111 by a snap-fit ​​structure.

[0044] Please combine Figure 3 and Figure 4 In some implementations, the snap-fit ​​structure includes a snap-fit ​​groove 410 and a snap-fit ​​block 420, which are respectively disposed on the cover 200 and the housing 100. In one example, the snap-fit ​​groove 410 is disposed on the side wall of the column 220, and the snap-fit ​​block 420 is disposed on the mounting opening wall 111. In another example, the snap-fit ​​groove 410 is disposed on the mounting opening wall 111, and the snap-fit ​​block 420 is disposed on the side wall of the column 220. This application embodiment will be described with the snap-fit ​​groove 410 disposed on the cover 200 and the snap-fit ​​block 420 disposed on the housing 100 as an example.

[0045] The snap-fit ​​slot 410 includes a first opening 411 through which the snap-fit ​​block 420 enters the snap-fit ​​slot 410. The snap-fit ​​slot 410 includes a bottom 412 and a wall 413, with the wall 413 adjacent to the bottom 412. The wall 413 includes a first wall 414, a second wall 415, and a third wall 416, wherein the second wall 415 connects the first wall 414 and the third wall 416, and the first wall 414 faces the third wall 416. The locking block 420 within the locking groove 410 is located between the first locking groove wall 414 and the third locking groove wall 416. The first locking groove wall 414 and the third locking groove wall 416 abut against the locking block 420 to lock the locking block 420 within the locking groove 410 and prevent the column 220 from moving out of the mounting opening 110, thereby mounting the cover 200 onto the housing 100. The locking block 420 can also leave the locking groove 410 through the first opening 411 to remove the cover 200 from the housing 100.

[0046] In the above example, the first opening 411 is located at one end of the latching groove 410, and the second latching groove wall 415 is located at the other end of the latching groove 410. The direction of the first opening 411 pointing to the second latching groove wall 415 has a preset angle with the center line of the column 220. Thus, as the latching block 420 moves from the first opening 411 to the second latching groove wall 415, the column 220 rotates relative to the cover 200. When the cover 200 is installed on the housing 100, the latching block 420 can abut against the second latching groove 410 to move away from the first opening 411 and prevent it from sliding out of the latching groove 410.

[0047] With the above settings, the user can rotate the cover 200 to move the locking block 420 from the first opening 411 to the second locking groove wall 415 to install the cover 200 on the housing 100; the user can also rotate the cover 200 to move the locking block 420 away from the first opening 411 to remove the cover 200 from the housing 100.

[0048] In the above implementation, the snap-fit ​​structure may further include a guide groove 430. The guide groove 430 includes a first guide groove wall 431, and a first opening 411 is disposed on the first guide groove wall 431, so that the snap-fit ​​groove 410 communicates with the guide groove 430. The guide groove 430 also includes a second opening 433, through which the snap-fit ​​block 420 can enter the guide groove 430, and then through the first opening 411 into the snap-fit ​​groove 410. Thus, the snap-fit ​​block 420 enters the snap-fit ​​groove 410 under the guidance of the guide groove 430.

[0049] The second opening 433 faces the inside of the mounting opening 110, so that when the column 220 faces the mounting opening 110, the locking block 420 faces the second opening 433. During the process of installing the cover 200 into the housing 100, the column 220 moves into the mounting opening 110 along the center line of the mounting opening 110, and at the same time, the second opening 433 moves toward the locking block 420, so that the locking block 420 enters the second opening 433.

[0050] In some implementations, the guide groove 430 further includes a second guide groove wall 432, which is disposed opposite to the second opening 433. The second guide groove wall 432 includes a first end near the cover plate 210 and a second end away from the cover plate 210, wherein the first end is near the second opening 433 and the second end is near the first opening 411. With the above arrangement, the locking block 420 can move along the second guide groove wall 432 within the guide groove 430 to enter the first opening 411 under the guidance of the second guide groove wall 432.

[0051] In the above embodiment, the direction from the first end to the second end of the second guide groove wall 432 has a preset angle with the center line of the column 220. Therefore, as the locking block 420 moves along the second guide groove wall 432 from the first end to the second end, the column 220 rotates relative to the mounting opening 110. With this configuration, the second guide groove wall 432 can be used to guide the rotation of the cover 200, facilitating the installation of the cover 200 onto the housing 100.

[0052] In one optional embodiment, the locking block 420 is provided with a first positioning groove, and the locking groove 410 is provided with a first positioning protrusion. The first positioning protrusion can be provided on at least one of the bottom 412 of the locking groove and the wall 413 of the locking groove. When the locking block 420 abuts against the second locking groove wall 415, the first positioning protrusion is engaged in the first positioning groove to prevent the locking block 420 from moving within the locking groove 410, thereby preventing the column 220 from rotating relative to the housing 100 and preventing the cover 200 from falling off the housing 100. Of course, in other optional embodiments, the first positioning groove can be provided within the locking groove 410, and the first positioning protrusion can be provided on the locking block 420.

[0053] In one optional embodiment, multiple locking blocks 420 and locking slots 410 can be provided, with each locking block 420 locking into a different locking slot 410. In one example, two locking blocks 420 and two locking slots 410 are provided, with the two locking slots 410 respectively located on both sides of the cover 200. In other examples, three or more locking blocks 420 and locking slots 410 can be provided, with the multiple locking slots 410 arranged around the central angle of the cover 200.

[0054] For other implementations, please refer to Figure 5The snap-fit ​​structure may further include a first snap-fit ​​460, a second snap-fit ​​470, and an elastic arm 480. The first snap-fit ​​460 is disposed on the elastic arm 480, and the elastic arm 480 and the second snap-fit ​​470 are respectively disposed on the cover 200 and the housing 100. The second snap-fit ​​470 is provided with a snap-fit ​​position 471. When the first snap-fit ​​460 is located in the snap-fit ​​position 471, the second snap-fit ​​470 abuts against the first snap-fit ​​460 to prevent the cover 200 from moving relative to the housing 100. The first snap-fit ​​460 is provided with a first mating surface 461, and the second snap-fit ​​470 is provided with a second mating surface 472. The second mating surface 472 is used to abut against the first mating surface 461 to guide the first snap-fit ​​460 into the snap-fit ​​position 471.

[0055] In the above embodiments, please refer to Figure 3 and Figure 5 The elastic arm 480 can be set on the column 220. The length direction of the elastic arm 480 can be parallel to the center line of the column 220, or the length direction of the elastic arm 480 can have a preset angle with the center line of the column 220.

[0056] In one optional embodiment, multiple first buckles 460, second buckles 470 and elastic arms 480 can be provided, with each first buckle 460 being provided on a different elastic arm 480, and each first buckle 460 being engaged with a different second buckle 470.

[0057] In the above embodiments, the snap-fit ​​structure simplifies the disassembly and assembly of the cover 200 and avoids the use of fasteners such as screws and bolts, reducing the number of parts in the image acquisition device 10 and lowering material and labor costs.

[0058] In one alternative embodiment, please refer back to Figure 2 The snap-fit ​​structure may further include a second positioning groove 440 and a second positioning protrusion 450, which are respectively disposed on the cover 200 and the housing 100. In one example, the second positioning groove 440 may be disposed on the cover 200, and the second positioning protrusion 450 may be disposed on the housing 100. In another example, the second positioning groove 440 may be disposed on the housing 100, and the second positioning protrusion 450 may be disposed on the cover 200. For example, the second positioning groove 440 may be disposed on the mounting portion, and the second positioning protrusion 450 may be disposed on the cover plate 210. When the cover 200 is mounted on the housing 100, the second positioning protrusion 450 may be engaged within the second positioning groove 440 to prevent the cover 200 from rotating relative to the housing 100 and to prevent the cover 200 from falling off the housing 100.

[0059] In some implementation methods, please combine Figure 2 , Figure 3 and Figure 4When the second positioning protrusion 450 is engaged in the second positioning groove 440, the locking block 420 abuts against the wall 415 of the second engaging groove. Thus, the second positioning protrusion 450 and the second positioning groove 440 can be used to position the cover 200 and the locking block 420, ensuring that the locking block 420 abuts against the wall 415 of the second engaging groove. With the above arrangement, during the process of assembling the cover 200 into the housing 100, when the second positioning protrusion 450 is engaged in the second positioning groove 440, it can be considered that the cover 200 and the housing 100 are assembled. During the process of assembling multiple covers 200 into multiple housings 100, the second positioning groove 440 and the second positioning protrusion 450 can reduce the assembly error between each cover 200 and each housing 100.

[0060] In one alternative embodiment, please refer to Figure 2 The image acquisition device 10 also includes a connecting rope, which may be made of at least one of nylon, polyethylene, and latex. One end of the connecting rope is connected to the cover 200, for example, the connecting rope may be connected to the cover plate 210, or the connecting rope may be connected to the column 220; the other end of the connecting rope is connected to the housing 100 to connect the cover 200 and the housing 100. With the above arrangement, when the cover 200 is removed from the housing 100, the cover 200 can be hung on the housing 100 by the connecting rope, which facilitates operation and prevents the cover 200 from being lost.

[0061] In the embodiment where the connecting rope is connected to the column 220, a clearance groove may be provided on the side wall of the column 220. When the cover 200 is installed on the housing 100, the clearance groove is located between the column 220 and the mounting opening wall 111. The connecting rope may be located within the clearance groove to avoid the connecting rope interfering with the rotation of the cover 200.

[0062] Please combine Figure 2 , Figure 6 and Figure 7 The image acquisition device 10 of this application embodiment also includes a sealing ring 600. The material used to make the sealing ring 600 may include at least one of rubber, polytetrafluoroethylene, and polyurethane. The sealing ring 600 is disposed on the cover 200 and is used to abut against the housing 100 to improve the sealing performance between the cover 200 and the housing 100. In one example, the sealing ring 600 may be disposed at the end of the column 220 away from the cover plate 210. In another example, a sealing groove is provided on the column 220, and the sealing ring 600 is located in the sealing groove and sleeved on the column 220. The sealing groove is used to hold the sealing ring 600 on the column 220 to prevent the sealing ring 600 from being misaligned. The sealing ring 600 is used to abut against the mounting port wall 111 to improve the sealing performance between the cover 200 and the housing 100.

[0063] In the above embodiments, the second positioning groove 440 and the second positioning protrusion 450 can be used to position the cover 200 to ensure that the sealing ring 600 abuts against the housing 100 and to ensure the sealing between the cover 200 and the housing 100.
