In addition, for the convenience and clarity of the description, the thickness or size of each element in the drawings is expressed in an exaggerated, omitted or schematic manner for the understanding and reading of those skilled in the art, and the size of each element is not completely its actual size, and is not used to limit the limiting conditions that the present invention can be implemented, so it has no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the efficacy and purpose that the present invention can produce, should still fall within the scope of the technical content disclosed by the present invention. The same reference numerals will be used to represent the same or similar elements in all drawings.

[0078] Figure 1 FIG. 4 is a side view of an image acquisition module according to an embodiment of the present invention. Figure 2 yes Figure 1 A stereoscopic view of a steering base. Figure 3 yes Figure 1Cross-sectional view of the steering base. Figures 1 to 3 The image acquisition module 10 of this embodiment includes a steering base 100 and an image acquisition unit 200. The image acquisition module 10 is, for example, an outdoor monitor, which can acquire images of the external environment through the image acquisition unit 200, and adjust the position and angle of the image acquisition unit 200 through the steering base 100, but the application scope of the image acquisition module 10 is not limited thereto.

[0079] The steering base 100 of the present embodiment includes a first housing 110, a second housing 120, a steering assembly 130, an elastic tube 140 ( Figure 3 ) and at least one annular elastic member 150 ( Figure 3 ). The first shell 110 can be set on the ceiling or the wall, for example, but the present invention is not limited to this. The image acquisition unit 200 is set in the second shell 120, and the steering assembly 130 is connected between the first shell 110 and the second shell 120. The elastic tube 140 is inserted into the steering assembly 130 and extends from the first shell 110 to the second shell 120. The annular elastic member 150 is sleeved on the elastic tube 140 and is compressed between the first shell 110 and the elastic tube 140. Thereby, the intrusion of external moisture into the steering base 100 can be effectively prevented, an excellent waterproof effect is achieved, and the mobility of the steering base 100 is taken into account. The following is a detailed description of this design.

[0080] Figure 4 yes Figure 2 Exploded view of the steering base. Figure 3 and Figure 4 The first housing 110 has an annular structure 112 and an opening H. The annular structure 112 protrudes from the upper surface S of the first housing 110 and surrounds a receiving space SP, which can accommodate the annular elastic member 150. The opening H is located in the receiving space SP and allows the elastic tube 140 to pass through.

[0081] The annular elastic member 150 includes two semi-annular elastic bodies 151 and 152 ( Figure 4 ), the two semi-annular elastic bodies 151 and 152 are close to each other to form an annular shape. The annular structure 112 surrounds the elastic tube 140, and the elastic tube 140 passes through the opening H and the central hole H1 of the annular elastic member 150. The annular elastic member 150 is compressed between the annular structure 112 of the first shell 110 and the elastic tube 140 along the radial direction D1 of the elastic tube 140.

[0082] Furthermore, the material of the elastic tube 140 and the material of the annular elastic member 150 are, for example, rubber, which is elastic and deformable. The material of the annular elastic member 150 of the present embodiment is different from the material of the elastic tube 140, for example, the elastic coefficient of the annular elastic member 150 is greater than the elastic coefficient of the elastic tube 140. Since the elastic coefficient of the elastic tube 140 is relatively low, the elastic tube 140 is easy to deform and can bend with the steering of the steering assembly 130 without affecting the mobility of the steering base 100. On the other hand, since the elastic coefficient of the annular elastic member 150 is relatively high, the annular elastic member 150 is not easy to deform and can be tightly pressed between the elastic tube 140 and the annular structure 112 of the first shell 110 to prevent external moisture from entering the first shell 110 through the accommodating space SP, thereby achieving good waterproof performance.

[0083] The specific structure of the steering assembly 130 of the present embodiment is described in detail below. The steering assembly 130 of the present embodiment includes a steering member 131 and a fixing member 132. The fixing member 132 is fixed to the first housing 110, the steering member 131 is movably connected to the fixing member 132, and the second housing 120 is fixed to the steering member 131. Specifically, the fixing member 132 includes a bearing member 135, a limiting member 136 and a cover 137. The bearing member 135 is locked and fixed to the upper surface S of the first housing 110. The cover 137 is screwed to the bearing member 135 to buckle the limiting member 136 on the bearing member 135.

[0084] The stopper 136 has a ball joint groove G and a stopper opening L ( Figure 4 ), the steering member 131 has a ball joint 133. The ball joint 133 is ball-connected to the ball joint groove G, and a portion of the steering member 131 extends from the limit opening L and can rotate along the limit opening L relative to the fixing member 132, so that the second housing 120 is turned relative to the first housing 110, thereby adjusting the image acquisition unit 200 ( Figure 1 ) relative to the position and angle of the first shell 110.

[0085] Figure 5A yes Figure 2 A partial 3D cutaway view of the steering base. The electrical wires are hidden to clearly show the elastic tube. Please refer to Figure 5A The fixing member 132 can limit the annular elastic member 150 on the first housing 110 along the axial direction D2 of the elastic tube 140. In detail, the steering base 100 further includes an annular fixing sheet 160, and the material of the annular fixing sheet 160 is, for example, metal, but the material of the annular fixing sheet 160 is not limited thereto.

[0086] The annular fixing sheet 160 is adjacent to the carrier 135 and the annular elastic member 150. When the carrier 135 is locked to the upper surface S of the first shell 110, the carrier 135 presses against the annular fixing sheet 160 and limits the annular elastic member 150 in the accommodation space SP of the first shell 110 along the axial direction D2 of the elastic tube 140. In another embodiment, the annular fixing sheet 160 can be integrally formed with the carrier 135.

[0087] In addition, the annular elastic member 150 is sleeved on one end E1 of the elastic tube 140. The end E1 of the elastic tube 140 has an annular step 141. The annular step 141 is formed on the outer peripheral surface CS of the elastic tube 140. The annular elastic member 150 is located between the annular step 141 and the bearing member 135 of the steering assembly 130 and blocks the annular step 141 along the axial direction D2 of the elastic tube 140 to prevent the elastic tube 140 from being pulled away from the annular elastic member 150 when the steering member 131 rotates, thereby affecting the waterproof effect of the steering base 100.

[0088] Figure 5B yes Figure 2 Another partial stereoscopic sectional view of the steering base. Figure 6 yes Figure 2 Please refer to the enlarged view of the elastic tube. Figure 5B and Figure 6 The other end E2 of the elastic tube 140 has an annular extension portion 142 , which extends from the outer circumferential surface CS of the elastic tube 140 along the radial direction D1 of the elastic tube 140 and is compressed between the second housing 120 and the steering member 131 of the steering assembly 130 .

[0089] Specifically, the annular extension portion 142 includes an annular flange portion 143 and two opposite surfaces S1 ( Figure 6 ), S2, and the annular flange portion 143 is formed on the surface S1 of the annular extension portion 142. The steering member 131 of the steering assembly 130 has an annular structure 134, which extends toward the second housing 120 and surrounds the elastic tube 140.

[0090] When the elastic tube 140 passes through the steering member 131 and the steering member 131 is locked in the second shell 120, the annular structure 134 of the steering member 131 presses against the surface S2 of the annular extension portion 142, and the annular flange portion 143 presses against the second shell 120, so that the annular extension portion 142 is compressed between the second shell 120 and the annular structure 134 along the axial direction D2 of the elastic tube 140, preventing external moisture from entering the second shell 120 from the gap between the steering member 131 and the second shell 120, thereby achieving excellent waterproof performance.

[0091] In addition, the annular extension portion 142 further has a curved section 144, which is curvedly connected to the outer circumferential surface CS of the elastic tube 140 and is located between the outer circumferential surface CS and the annular flange portion 143. The curved section 144 provides a margin for the elastic tube 140 to stretch, so as to prevent the elastic tube 140 from being excessively pulled and loosened or damaged when the steering member 131 rotates, thereby affecting the waterproof function of the steering base 100.

[0092] Please go back Figure 3 The turning base 100 further includes an electrical wire 170 and two circuit boards 180A and 180B. The circuit boards 180A and 180B are respectively disposed inside the first housing 110 and inside the second housing 120. The electrical wire 170 extends from the inside of the first housing 110 through the inside of the elastic tube 140 to the inside of the second housing 120, and the circuit boards 180A and 180B are electrically connected to each other through the electrical wire 170. By designing that the annular elastic member 150 is tightly pressed between the first shell 110 and the elastic tube 140, and the annular extension portion 142 of the elastic tube 140 is tightly pressed between the second shell 120 and the steering member 131, the interior of the first shell 110, the interior of the elastic tube 140 and the interior of the second shell 120 can form a sealed space together to prevent external moisture from entering the steering base 100 (for example, external moisture enters the interior of the first shell 110 of the steering base 100 through the fixing member 132 and the accommodating space SP of the steering assembly 130, or enters the interior of the second shell 120 through the gap between the steering member 131 and the second shell 120) and damaging the electrical wire 170 and the circuit boards 180A, 180B, so that a good waterproof effect can be achieved.

[0093] In the present embodiment, the annular elastic member 150 and the annular structure 112 are located in the first housing 110, and the annular extension portion 142 of the elastic tube 140 is located in the second housing 120. Of course, in other embodiments, the annular elastic member 150 and the annular structure 112 may be disposed in the second housing 120, and the annular extension portion 142 of the elastic tube 140 may be located in the first housing 110, that is, the configuration is upside down from the present embodiment, and the present invention is not limited thereto.

[0094] In addition, if both ends E1 and E2 of the elastic tube 140 have an integral ring shape (i.e., the ring-shaped extension 142), it will be impossible to demould and difficult to assemble in the manufacturing process. Therefore, one end E1 of the elastic tube 140 is designed to be a structure where the elastic tube 140 of the turning base 100 is separated from the ring-shaped elastic member 150, which is not only convenient for demoulding, but also easy to assemble to the first housing 110. In addition, this design does not need to be glued to the joints of the components to achieve the purpose of waterproofing, so it does not affect the mobility of the turning base 100 and is conducive to rework.

Figure 7B yes Fig. 7A Schematic diagram of an annular elastic member being compressed in the circumferential direction. Fig. 7A The embodiment shown is Figure 4 The main difference between the embodiments shown is that Fig. 7A The annular elastic member 150A is an annular elastic body and has a fracture C. The fracture C is along the radial direction D3 ( Figure 7B ) extends. The annular elastic member 150A may extend in the circumferential direction D4 ( Figure 7B ) is stretched open to facilitate the elastic tube 140 to pass through the annular elastic member 150A.

Figure 8B yes Fig. 8A A partial three-dimensional cross-sectional view of an annular elastic member disposed on a steering base. Fig. 8A The embodiment shown is Figure 4 The main difference between the embodiments shown is that Fig. 8A The annular elastic member 150B is a continuous annular structure and has an annular groove 153. Figure 8B As shown, one of the first shell 110 and the second shell 120 (shown as the first shell 110) has an annular convex rib 114. The elastic tube 140 is sleeved on the annular elastic member 150B and the annular elastic member 150B is located in the accommodation space SP, the annular groove 153 of the annular elastic member 150B is clamped on the annular convex rib 114, and the annular elastic member 150B is compressed between the annular structure 112 of the first shell 110 and the elastic tube 140 along the radial direction D1 of the elastic tube 140.

[0097] Fig. 9 It is a cross-sectional view of a steering base according to another embodiment of the present invention. Fig. 9 The embodiment shown is Figure 2 The main difference between the embodiments shown is that Fig. 9 The steering base 100A in the embodiment has two annular elastic members 150C and 150D. The annular elastic member 150C is compressed between the second housing 120A and the elastic tube 140, while the annular elastic member 150D is compressed between the first housing 110 and the elastic tube 140. That is, in this embodiment, not only the first housing 110 is provided with an annular elastic member 150D, but also the second housing 120A is provided with an annular elastic member 150C to replace Figure 3 In the illustrated embodiment, the second housing 120 is designed to be waterproof by means of the annular extension 142 .

[0098] In detail, the second housing 120A has an annular structure 122 and an opening H. The annular structure 122 surrounds a receiving space SP to accommodate the annular elastic member 150C, and the opening H is located in the receiving space SP. When the steering member 131A is fixed to the second housing 120A, the annular structure 134A of the steering member 131A abuts against the annular fixing sheet 160, and the annular fixing sheet 160 abuts against the annular elastic member 150C in the receiving space to limit the annular elastic member 150C in the receiving space SP of the second housing 120A. The electrical wire 170 can be connected to the circuit board 180B through the inside of the elastic tube 140 and the opening H of the second housing 120A. The elastic tube 140 extends to the second housing 120A, the annular structure 122 surrounds the elastic tube 140, and the elastic tube 140 passes through the central hole H2 of the annular elastic member 150C, so that the annular elastic member 150C is compressed between the annular structure 122 of the second housing 120A and the elastic tube 140 along the radial direction D1 of the elastic tube 140. The configuration of the annular elastic member 150D on the first housing 110 is the same or similar to the configuration of the annular elastic member 150, which will not be repeated here.

[0099] In summary, the steering assembly of the steering base of the present invention is connected between the first shell and the second shell, and the elastic tube body is inserted into the steering assembly. The design that the annular elastic member is sleeved on the elastic tube body and compressed between the elastic tube body and the first shell or the second shell, or the elastic tube body is compressed between the second shell and the steering member can effectively prevent external moisture from entering the steering base through the gap between the elastic tube body and the first shell or the second shell, avoid damage to the circuit board and electrical wires inside the steering base, and achieve good waterproof performance. In addition, since the steering base does not need to be glued to the joints of the components during the manufacturing process, the steering base has good mobility and is easy to rework.
