[0076] Figure 1 is a perspective view of an image acquisition module according to an embodiment of the present invention. Figure 2 is Figure 1 a side view of the image acquisition module of Figure 3 is Figure 2 a cross-sectional view of the image acquisition module of Figures 1 to 3 Please refer to

[0077] In this embodiment, the steering base 100 of the image acquisition module includes a first housing 110, a second housing 120, a steering assembly 130, two seals 140 ( Figure 3 ) and an electrical wire harness 150 ( Figure 3)。The image acquisition unit 20 is disposed in the first housing 110. The steering assembly 130 is connected between the first housing 110 and the second housing 120, wherein the connecting end 131 of the steering assembly 130 is connected to the second housing 120 and the other connecting end 138 of the steering assembly 130 is connected to the first housing 110. In addition, the image acquisition module 10 further includes two circuit boards 30, the two circuit boards 30 are respectively disposed inside the first housing 110 and inside the second housing 120, and the two circuit boards 30 are electrically connected through electrical wires 150.

[0078] Figure 4A is Figure 3 a three-dimensional view of the seal. Figure 4B is Figure 4A a three-dimensional view of the seal from another perspective. Figure 5A is Figure 3 a partial sectional view of the steering base in region A. Figure 5B is Figure 3 a partial sectional view of the steering base in region B. Please refer to Figure 4A and Figure 4B , each seal 140 includes a main body portion 141 and a tubular portion 142, the main body portion 141 is an annular structure, and the tubular portion 142 is connected to the main body portion 141 and extends outward from the center of the main body portion 141. The main body portions 141 of the two seals 140 are respectively disposed between the first housing 110 and the steering assembly 130 as shown in Figure 5A and between the inner space of the second housing 120 and the steering assembly 130 as shown in Figure 5B inside the second housing 120.

[0079] In this embodiment, the number of the seals 140 is two as described above, but the number of the seals 140 is not limited thereto. In other embodiments, the user can, according to the actual waterproofing requirements, dispose the seals 140 at the places where waterproofing is required. For example, when the circuit board 30 is only disposed inside the first housing 110 or the second housing 120, the seal 140 can be disposed only between the first housing 110 and the steering assembly 130 or only inside the second housing 120. In this embodiment, the main body portion 141 of the seal 140 is sealed in the gap G1 between the steering assembly 130 and the first housing 110 as shown in Figure 5A , and the main body portion 141 of the other seal 140 is sealed in the gap G2 at the connecting end 131 of the steering assembly 130 as shown in Figure 5B .

[0080] It should be noted that the shape and thickness of the annular structure of the main body portion 141 can be adjusted according to the shape and size of the gaps G1 and G2 to achieve a good waterproof effect, and the present invention does not limit the shape and thickness of the annular structure of the main body portion 141.

[0081] Continuing from the above, the electrical wire 150 extends from the inside of the first housing 110 through the steering assembly 130 to the inside of the second housing 120. Moreover, the electrical wire 150 passes through the tubular portion 142 and abuts against the inner wall of the tubular portion 142.

[0082] As described above, in the steering base 100 of the present embodiment, a seal 140 is provided between the first housing 110 and / or the second housing 120 and the steering assembly 130, and the seal 140 has a tubular portion 142 for sleeving the electrical wire 150. Accordingly, the close combination of the electrical wire 150 and the tubular portion 142 can prevent external water from entering the inside of the first housing 110 and the second housing 120, thereby making the steering base 100 have good waterproof performance. In addition, since the steering base 100 is waterproof by providing the seal 140 instead of by gluing, it is easy to disassemble, assemble and rework. Moreover, in the present embodiment, by providing the seal 140 in the above manner at the connection between the first housing 110 and / or the second housing 120 and the steering assembly 130, the waterproof effect can be achieved without completely covering the electrical wire 150 with a waterproof sleeve inside the steering base 100, which has the effects of saving material costs and being easy to assemble.

[0083] In the present embodiment, the material of the seal 140 is, for example, rubber or other elastic materials, but the present invention does not limit the material of the seal 140.

[0084] The structure of the steering base 100 will be described in more detail below. Please continue to refer to Figure 5A , the steering base 100 of the present embodiment further includes at least one fastener 160, and the first housing 110 and the steering assembly 130 are fastened to each other by the fastener 160. In addition, the main body portion 141 of the seal 140 provided between the first housing 110 and the steering assembly 130 has a plurality of through holes 1413 as shown in Figure 4A . When the fastener 160 fastens the first housing 110 and the steering assembly 130 to each other, the fastener 160 passes through one of the through holes 1413. In addition, the steering assembly 130 has at least one positioning post 132, and the positioning post 132 passes through another of the through holes 1413 to position the seal 140.

[0085] In the present embodiment, the main body portion 141 has six through holes 1413, and these through holes 1413 are equidistantly arranged around the main body portion 141 and surround the tubular portion 142, but the number and position of the through holes 1413 are not limited to the above.

[0086] Please continue to refer to Figure 5A and Figure 5B, the steering assembly 130 of this embodiment includes a fixing structure 133, a steering member 134, a housing 135, and an adjusting member 136. The steering member 134 is fixed to the first housing 110 by a fastener 160, the fixing structure 133 is fixed to the second housing 120 by a fastener 170, and the steering member 134 is movably connected to the fixing structure 133. The adjusting member 136 is rotatably disposed in the housing 135.

[0087] In this embodiment, the adjusting member 136 is, for example, disposed on the part of the adjusting member 136 near the inner side of the housing 135 through a C-shaped buckle 137, so that the adjusting member 136 is rotatably disposed in the housing 135, but the present invention does not limit the fixing manner of the adjusting member 136.

[0088] Please continue to refer to Figure 5B , the fixing structure 133 further has a ball joint groove 1331, a seat body 1332, a pressing structure 1333, a fixing plate 1334, and a fixing piece 1335. The steering member 134 has a ball joint 1341. The ball joint 1341 is ball-jointed in the ball joint groove 1331 and is movably connected to the seat body 1332. The pressing structure 1333 is disposed between the second housing 120 and the seat body 1332, and one end of the pressing structure 1333 faces the seat body 1332. The fixing plate 1334 is fixed to the second housing 120 by a fastener 170, and the fixing plate 1334 stops the other end of the pressing structure 1333. The pressing structure 1333 can press the seat body 1332 toward the steering member 134 along the first direction D1. The fixing piece 1335 is fixed to the fixing plate 1334 by a fastener 180.

[0089] In addition, the pressing structure 1333 includes a first pressing block P1 and a second pressing block P2. The adjusting member 136 is screwed to the first pressing block P1 and is adapted to rotate to drive the first pressing block P1 to move along the second direction D2. The first pressing block P1 is movably disposed between the seat body 1332 and the second pressing block P2 along the second direction D2 and has a first inclined surface S1 inclined to the second direction D2. The second pressing block P2 has a second inclined surface S2 parallel to and abutted against the first inclined surface S1. The first pressing block P1 is adapted to move along the second direction D2 to make the first inclined surface S1 move along the second inclined surface S2, thereby changing the pressing force of the pressing structure 1333 on the seat body 1332 along the first direction D1.

[0090] For example, when the first pressing block P1 moves along the second direction D2, the acting force of mutual pushing between the first inclined surface S1 and the second inclined surface S2 in the first direction D1 increases, and thus the pressing force of the pressing structure 1333 on the seat body 1332 along the first direction D1 becomes larger, and the fixing force between the ball joint 1341 and the ball joint groove 1331 becomes larger to fix, such as Figure 1The position and angle of the image acquisition unit 20 shown. Conversely, when the first pressing block P1 moves in the reverse direction along the second direction D2, the acting force pushing against each other between the first inclined surface S1 and the second inclined surface S2 in the first direction D1 decreases. As a result, the abutting force of the abutting structure 1333 against the seat body 1332 in the first direction D1 becomes smaller, and the fixing force between the ball joint 1341 and the ball joint groove 1331 becomes smaller, making it easier for the user to adjust the position and angle of the image acquisition unit 20.

[0091] In this embodiment, during the assembly process, the electrical wire 150 is adapted to be sequentially passed through the tubular portion 142 of the seal 140 and the tubular portion 142 of another seal 140 along the passing direction PD. Accordingly, the tubular portions 142 of the two seals 140 both extend from the corresponding main body portion 141 along the passing direction PD. That is, the tubular portions 142 of the two seals 140 extend in the same direction. Such a design can improve the convenience and efficiency of the electrical wire 150 passing through the tubular portion 142. It should be noted that in this embodiment, the passing direction PD is parallel to the first direction D1, and the first direction D1 is perpendicular to the second direction D2, but the present invention does not limit the relative relationship between the passing direction PD, the first direction D1, and the second direction D2.

[0092] In this embodiment, in order to enable the seal 140 to effectively exert the sealing effect, the main body portion 141 has at least one annular flange 1411 (as Figure 4A , Figure 4B shown), the annular flange 1411 surrounds the tubular portion 142 and is compressed by at least one of the first housing 110 and the steering assembly 130 as Figure 5A shown and is compressed by at least one of the fixing piece 1335 and the fixing plate 1334 as Figure 5B shown. Specifically, the size of the seal 140 in this embodiment can be designed such that in the absence of the annular flange 1411, Figure 5A the first surface A1 of the main body portion 141 of the seal 140 shown abuts against the steering member 134 without being compressed and the second surface A2 abuts against the first housing 110 without being compressed, Figure 5B the first surface A1 of the main body portion 141 of another seal 140 shown abuts against the fixing piece 1335 without being compressed and the second surface A2 abuts against the fixing plate 1334 without being compressed. Thus, the additionally formed annular flange 1411 on the main body portion 141 can be effectively compressed to exert the sealing effect.

[0093] In this embodiment, the number of annular flanges 1411 of the main body portion 141 of each seal 140 is four, and each surface of the main body portion 141 has two annular flanges 1411, and these two annular flanges 1411 are concentrically arranged. The number of annular flanges 1411 is not limited to the above.

[0094] In addition, the main body portion 141 of this embodiment, as Figure 4A shown, has an annular concave groove 1412, and the annular concave groove 1412 surrounds the tubular portion 142. By forming the annular concave groove 1412 in the main body portion 141 in this embodiment, the tubular portion 142 can have an elastic deformation ability sufficient to withstand the pulling during assembly and / or when the steering component 130 is actuated, so that a good sealing performance can be maintained between the electrical wire 150 and the tubular portion 142.

[0095] On the other hand, as Figure 5B shown, the steering base 100 of this embodiment further includes a waterproof ring 190, which is disposed between the second housing 120 and the fixing plate 1334 to prevent external water from entering the interior of the second housing 120 through the gap between the second housing 120 and the fixing plate 1334.

[0096] To sum up, in the steering base of the present invention, a seal is provided between the first housing and / or the second housing and the steering component, and the seal has a tubular portion for sleeving the electrical wire. Accordingly, by the tight combination of the electrical wire and the tubular portion, external water can be prevented from entering the interiors of the first housing and the second housing, and thus the steering base has good waterproof performance. In addition, since the waterproofing of the steering base is achieved by providing a seal rather than by gluing, it is easy to disassemble, assemble and rework. Moreover, by providing the seal in the above manner at the connection between the first housing and / or the second housing and the steering component, the waterproof effect can be achieved in the present invention, without the need to completely cover the electrical wire with a waterproof sleeve inside the steering base, resulting in the effects of saving material costs and being easy to assemble.

[0097] Although the technical content of the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art, without departing from the spirit of the present invention, makes some modifications and refinements, and all should be covered within the scope of the present invention.
