[0019] In the embodiments of this application, since the first protrusion of the first bracket is sleeved within the first accommodating cavity of the second bracket, the second bracket can rotate relative to the first bracket when the first threaded connector is loosened. Therefore, the orientation of the camera module of the camera device can be adjusted by rotating the second bracket relative to the first bracket.

[0020] Furthermore, since the first uneven portion of the end face of the first protrusion faces the second uneven portion of the cavity wall of the first accommodating cavity, the first threaded connector can be tightened to push against the first annular abutment surface, thereby tightly connecting the first uneven portion and the second uneven portion, resulting in a locking fit between the first uneven portion and the second uneven portion. Thus, after adjusting the camera module of the camera device to a suitable orientation, tightening the first threaded connector can prevent the second bracket from rotating relative to the first bracket.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0052] Furthermore, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application specification may have been selected by the applicant at his or her own discretion, and their detailed meanings are explained in the relevant sections of this description.

[0053] Furthermore, this application is required to be understood not only through the actual terms used, but also through the meaning implied by each term.

[0054] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0055] This application provides a support mechanism for a camera device. (See reference...) Figures 1 to 4 The camera device support mechanism 100 provided in this application embodiment includes: a first bracket 110, a second bracket 120 and a first threaded connector 130.

[0056] refer to Figures 1 to 3 , Figure 4and Figure 7 The first support 110 has a first protrusion 111 extending along a first direction. The second support 120 has a first receiving cavity 121. The first protrusion 111 is fitted into the first receiving cavity 121 so that the second support 120 can rotate relative to the first support 110 about a first axis 100a. The first axis 100a is parallel to the first direction.

[0057] The end face of the first protrusion 111 is provided with a first undulating portion 1111. The cavity wall of the first receiving cavity 121 is provided with a second undulating portion 1211, which is opposite to the first undulating portion 1111. The first protrusion 111 is also provided with a first annular abutment surface 1112. The first threaded connector 130 is threadedly connected to the second bracket 120, and the end of the first threaded connector 130 abuts against the first annular abutment surface 1112, so that the first undulating portion 1111 and the second undulating portion 1211 are engaged.

[0058] In this manner, in the embodiments of this application, since the first protrusion 111 of the first bracket 110 is fitted into the first receiving cavity 121 of the second bracket 120, the second bracket 120 can rotate relative to the first bracket 110 when the first threaded connector 130 is loosened. Furthermore, the orientation of the camera module of the camera device can be adjusted by rotating the second bracket 120 relative to the first bracket 110.

[0059] Furthermore, since the first uneven portion 1111 of the end face of the first protrusion 111 is opposite to the second uneven portion 1211 of the cavity wall of the first receiving cavity 121, the first threaded connector 130 can be tightened to push against the first annular abutment surface 1112, thereby making the first uneven portion 1111 and the second uneven portion 1211 tightly connected, thus making the first uneven portion 1111 and the second uneven portion 1211 locked together. In this way, after the camera module of the camera device is adjusted to a suitable orientation, the second bracket 120 can be prevented from rotating relative to the first bracket 110 by tightening the first threaded connector 130.

[0060] Since the solution provided in this application embodiment can be adopted, the rotation of the rotating part between the second bracket 120 and the first bracket 110 can be restricted, thus preventing the support mechanism of the camera module from rotating on its own due to accident.

[0061] refer to Figures 3 to 6 In some embodiments, the first protrusion 111 includes a first body 1113 and a first metal ring 1114 clamped around the outer periphery of the first body 1113. The end of the first threaded connector 130 abuts against the outer surface of the first metal ring 1114.

[0062] For example, the first main body of the first bracket 110 is made of plastic, and thus the first body 1113 of the first protrusion 111 is also made of plastic. The first metal ring 1114 can be bonded to the outer periphery of the first body 1113, or it can be fitted onto the outer periphery of the first body 1113 by means of insert molding. Furthermore, the first annular abutment surface 1112 is located on the outer surface of the first metal ring 1114.

[0063] In this way, by setting a first metal ring 1114 on the outer periphery of the first body 1113, the end of the first threaded connector 130 abuts against the outer surface of the first metal ring 1114, thereby improving the service life of the first bracket 110.

[0064] In some embodiments, the outer surface of the first metal ring 1114 has a tapered structure with one end larger than the other. Specifically, the diameter of the end of the outer surface of the first metal ring 1114 facing the first undulating portion 1111 is larger than the diameter of the end of the outer surface of the first metal ring 1114 away from the first undulating portion 1111. Exemplarily, the first metal ring 1114 is formed by sheet metal processing, that is, the first metal ring 1114 is a first sheet metal ring. The inclination angle of the outer surface of the first metal ring 1114 is 15 to 20 degrees. The screwing direction of the first threaded connector 130 is perpendicular to the first axis 100a.

[0065] refer to Figure 1 , Figure 2 , Figures 8 to 10 In some embodiments, the support mechanism 100 further includes a third bracket 140 and a second threaded connector 150. The second bracket 120 includes a first side portion 122 and a second side portion 123 disposed opposite each other along a second direction. One end of the third bracket 140 is disposed between the first side portion 122 and the second side portion 123.

[0066] The first side portion 122 is provided with a first hole 1221. The third bracket 140 is provided with a first threaded hole 141 on the side facing the first side portion 122, and the axis of the first threaded hole 141 is parallel to the second direction. The second threaded connector 150 passes through the first hole 1221 and is threadedly connected to the first threaded hole 141. The third bracket 140 can rotate relative to the second bracket 120 about the second axis 100b, wherein the second axis 100b is collinear with the axis of the first threaded hole 141.

[0067] Thus, when the support mechanism 100 includes a third bracket 140, and the third bracket 140 is rotatable relative to the second bracket 120, when it is necessary to restrict the rotation of the third bracket 140 relative to the second bracket 120, the friction between the first side 122 and the third bracket 140 can be increased by tightening the second threaded connector 150, so as to restrict the rotation of the third bracket 140 relative to the second bracket 120.

[0068] refer to Figure 8 In some embodiments, the end of the second threaded connector 150 opposite to the first threaded hole 141 is provided with a stop portion 151, and the first side portion 122 is sandwiched between the stop portion 151 and the third bracket 140.

[0069] refer to Figures 8 to 10 In some embodiments, the first side portion 122 has a third undulating portion 1222 on its side facing the third bracket 140, and the third bracket 140 has a fourth undulating portion 142, which is opposite to the third undulating portion 1222. The fourth undulating portion 142 and the third undulating portion 1222 are engaged under the locking force of the second threaded connector 150. In this way, by providing the third undulating portion 1222 and the fourth undulating portion 142 between the first side portion 122 and the third bracket 140, the performance of restricting the rotation of the third bracket 140 of the support mechanism 100 relative to the second bracket 120 can be further improved.

[0070] refer to Figures 8 to 10 In some embodiments, the support mechanism 100 further includes a third threaded connector 160. The second side portion 123 has a second threaded hole 1231, the axis of which is collinear with the axis of the first threaded hole 141. The third bracket 140 has a second hole 143 on the side facing the second side portion 123. The third threaded connector 160 is threadedly connected to the second threaded hole 1231. The third threaded connector 160 has a rotating shaft portion 161 on the side facing the second hole 143, which is inserted into the second hole 143 and engages with the shaft hole of the second hole 143. Thus, when the second threaded connector 150 is released, the third bracket 140 can rotate relatively smoothly relative to the second bracket 120.

[0071] refer to Figures 11 to 13 In some embodiments, the third support 140 has a second protrusion 144 at one end opposite to the second support 120. The support mechanism 100 also includes a fourth support 170, which has a second receiving cavity 171. The second protrusion 144 is sleeved in the second receiving cavity 171 so that the fourth support 170 can rotate relative to the third support 140 about the third axis 100c.

[0072] In some embodiments, the end face of the second protrusion 144 is provided with a fifth undulating portion 1441, and the cavity wall of the second receiving cavity 171 is provided with a sixth undulating portion 1711. The sixth undulating portion 1711 is opposite to the fifth undulating portion 1441, and the second protrusion 144 is also provided with a second annular abutment surface 1442. The support mechanism 100 also includes a fourth threaded connector 180, which is threadedly connected to the fourth bracket 170. The end of the fourth threaded connector 180 abuts against the second annular abutment surface 1442, so that the fifth undulating portion 1441 and the sixth undulating portion 1711 are engaged.

[0073] Thus, since the second protrusion 144 of the third bracket 140 is fitted into the second receiving cavity 171 of the fourth bracket 170, the fourth bracket 170 can rotate relative to the third bracket 140 when the fourth threaded connector 180 is loosened. Furthermore, the orientation of the camera module of the camera device can be adjusted by rotating the fourth bracket 170 relative to the third bracket 140.

[0074] Furthermore, since the fifth undulating portion 1441 of the end face of the second protrusion 144 is opposite to the sixth undulating portion 1711 of the cavity wall of the second accommodating cavity 171, the fourth threaded connector 180 can be tightened to push against the second annular abutment surface 1442, thereby making the fifth undulating portion 1441 and the sixth undulating portion 1711 tightly connected, thus making the fifth undulating portion 1441 and the sixth undulating portion 1711 locked together. In this way, after the camera module of the camera device is adjusted to a suitable orientation, the fourth bracket 170 can be prevented from rotating relative to the third bracket 140 by tightening the fourth threaded connector 180.

[0075] For example, the first undulating portion 1111 is a first tooth-shaped portion, and the second undulating portion 1211 is a second tooth-shaped portion. The shape of the second tooth-shaped portion is adapted to the shape of the first tooth-shaped portion, so that the second protruding tooth of the second tooth-shaped portion can be engaged with the first tooth groove between two adjacent first protruding teeth of the first tooth-shaped portion.

[0076] The third undulating portion 1222 is the third tooth-shaped portion, and the fourth undulating portion 142 is the fourth tooth-shaped portion. The shape of the fourth tooth-shaped portion is adapted to the third tooth-shaped portion so that the fourth protruding tooth of the fourth tooth-shaped portion can be engaged with the third tooth groove between the two adjacent third protruding teeth of the third tooth-shaped portion.

[0077] The fifth undulating portion 1441 is the fifth tooth-shaped portion, and the sixth undulating portion 1711 is the sixth tooth-shaped portion. The shape of the sixth tooth-shaped portion is adapted to the fifth tooth-shaped portion so that the sixth protruding tooth of the sixth tooth-shaped portion can be engaged with the fifth tooth groove between the two adjacent fifth protruding teeth of the fifth tooth-shaped portion.

[0078] In some embodiments, the second protrusion 144 includes a second body 1443 and a second metal ring 1444 clamped around the outer periphery of the second body 1443. The end of the fourth threaded connector 180 abuts against the outer surface of the second metal ring 1444.

[0079] For example, the third main body of the third bracket 140 is made of plastic, and thus the second body 1443 of the second protrusion 144 is also made of plastic. The second metal ring 1444 can be bonded to the outer periphery of the second body 1443, or it can be fitted onto the outer periphery of the second body 1443 by insert molding. Furthermore, the second annular abutment surface 1442 is located on the outer surface of the second metal ring 1444.

[0080] In this way, by setting a second metal ring 1444 on the outer periphery of the second body 1443, the end of the fourth threaded connector 180 abuts against the outer surface of the second metal ring 1444, thereby improving the service life of the third bracket 140.

[0081] In some embodiments, the outer surface of the second metal ring 1444 has a tapered structure with one end larger than the other. Specifically, the diameter of the end of the outer surface of the second metal ring 1444 facing the fifth undulating portion 1441 is larger than the diameter of the end of the outer surface of the second metal ring 1444 away from the fifth undulating portion 1441. Exemplarily, the second metal ring 1444 is formed by sheet metal processing, that is, the second metal ring 1444 is a second sheet metal ring. The inclination angle of the outer surface of the second metal ring 1444 is 15 to 20 degrees. The screwing direction of the fourth threaded connector 180 is perpendicular to the first axis 100a.

[0082] refer to Figure 2 , Figure 3 and Figure 8 In some embodiments, the first axis 100a is perpendicular to the second axis 100b, and the third axis 100c is perpendicular to the second axis 100b.

[0083] refer to Figure 4 In some embodiments, the first main body of the first support 110 is made of plastic. In other words, the first main body of the first support 110 is specifically a first plastic main body. The first metal ring 1114 is connected to the first main body by means of insert molding to form the first support 110.

[0084] refer to Figure 3 The second main body of the second bracket 120 is made of plastic; in other words, the second main body of the second bracket 120 is specifically a second plastic main body. A first metal nut 124 is embedded in the second main body. A first threaded connector 130 is threadedly connected to the first metal nut 124. (Reference) Figure 8 The second main body is also fitted with a second metal nut 125. The threaded hole of the second metal nut 125 forms a second threaded hole 1231, and the third threaded connector 160 is threadedly connected to the second metal nut 125.

[0085] refer to Figure 8 In some embodiments, the third main body of the third bracket 140 is made of plastic; in other words, the third main body of the third bracket 140 is specifically a third plastic main body. A third metal nut 145 is embedded in the third main body. The second threaded connector 150 is threadedly connected to the third metal nut 145.

[0086] refer to Figure 11 In some embodiments, the fourth main body of the fourth bracket 170 is made of plastic; in other words, the fourth main body of the fourth bracket 170 is specifically a fourth plastic main body. A fourth metal nut 172 is embedded in the fourth main body. The fourth threaded connector 180 is threadedly connected to the fourth metal nut 172.

[0087] In this way, by making the main body of the first bracket 110, the second bracket 120, the third bracket 140, and the fourth bracket 170 all made of plastic, the corrosion resistance of each bracket can be improved. In addition, the weight and production cost of each bracket can be reduced.

[0088] refer to Figure 14 This application provides a camera device. The camera device 1 provided in this application includes: a camera module 200 and any of the support mechanisms 100 provided in this application, wherein the camera module 200 is connected to the support mechanism 100.

[0089] For example, combined Figure 1 The camera module 200 can be connected to the fourth bracket 170. Additionally, the first bracket 110 can be connected to a mounting base, such as a wall.

[0090] This application provides another imaging device. (See reference...) Figures 1 to 14 The camera device 1 provided in this application embodiment includes: a support mechanism 100 and a camera module 200.

[0091] The support mechanism 100 includes a first bracket 110, a second bracket 120, a first threaded connector 130, a third bracket 140, a second threaded connector 150, and a fourth bracket 170. The first bracket 110 has a mounting section 112 for mechanically coupling the camera device 1 to the monitored scene. The fourth bracket 170 is connected to the camera module 200.

[0092] The camera device 1 has a first rotation state and a second rotation state. In the first rotation state, the first support 110 remains stationary, while the second support 120, third support 140, fourth support 170, and camera module 200 rotate synchronously about a first axis 100a relative to the first support 110. In the second rotation state, the first support 110 and second support 120 remain stationary, while the third support 140, fourth support 170, and camera module 200 rotate synchronously about a second axis 100b relative to the second support 120.

[0093] The second bracket 120 is provided with a third threaded hole 1241 and a first threaded hole 141. The locking force between the first threaded connector 130 and the third threaded hole 1241 limits the camera module 200 to be held at a first preset angle around the first axis 100a. The locking force between the second threaded connector 150 and the first threaded hole 141 limits the camera module 200 to be held at a second preset angle around the second axis 100b.

[0094] In this way, the locking force generated by the first threaded connector 130 and the second threaded connector 150 can keep the support mechanism 100 in a preset posture, so as to prevent the support mechanism 100 from rotating on its own due to accident, thereby causing the camera module 200 to shift.

[0095] In some embodiments, the second support 120 is provided with a first receiving cavity 121, and the first support 110 is provided with a first protrusion 111 extending in a first direction, the first receiving cavity 121 receiving the first protrusion 111. The second support 120 and the first support 110 are configured to engage in a locking fit in the first direction. In this way, after the support mechanism 100 is adjusted to the correct position, rotation of the second support 120 relative to the first support 110 can be prevented.

[0096] In some embodiments, the second support 120 includes a first side portion 122 and a second side portion 123 disposed opposite to each other along a second direction. The third support 140 is configured to engage with the first side portion 122 and / or the second side portion 123 in the second direction. In this way, rotation of the third support 140 relative to the second support 120 can be prevented after the support mechanism 100 has been adjusted to the correct position.

[0097] In some embodiments, the portion of the first bracket 110 that abuts against the first threaded connector 130 is made of metal, while the other portions of the first bracket 110 are made of plastic. The metal portion and the plastic portion of the first bracket 110 are formed by in-mold injection molding. It should be noted that since in-mold injection molding is a prior art technology, it will not be described in detail here.

[0098] In some embodiments, the camera device 1 further has a third rotation state in which it rotates about a third axis 100c. When the camera device 1 is in the third rotation state, the first bracket 110, the second bracket 120, and the third bracket 140 remain stationary, while the fourth bracket 170 and the camera module 200 rotate synchronously about the third axis 100c relative to the third bracket 140. Exemplarily, the third axis 100c is parallel to the optical axis of the camera module 200.

[0099] In some embodiments, the fourth support 170 is provided with a second receiving cavity 171, and the third support 140 has a second protrusion 144 at one end opposite to the second support 120, with the second receiving cavity 171 receiving the second protrusion 144. The fourth support 170 and the third support 140 are configured in a locking engagement in a direction parallel to the third axis 100c. This prevents the fourth support 170 from rotating relative to the third support 140 after the support mechanism 100 has been properly positioned.

[0100] In some embodiments, the fourth bracket 170 is provided with a fourth threaded hole 1721, and the support mechanism 100 further includes a fourth threaded connector 180. The portion of the third bracket 140 that abuts against the fourth threaded connector 180 is made of metal, and the remaining portion of the third bracket 140 is made of plastic. The metal portion and the plastic portion of the third bracket 140 are formed by in-mold injection molding.

[0101] In some embodiments, the first bracket 110 has a first wire-through hole, the second bracket 120 has a second wire-through hole, the third bracket 140 has a third wire-through hole, and the fourth bracket 170 has a fourth wire-through hole. Cables electrically connected to the camera module 200 can be passed through the first, second, third, and fourth wire-through holes, respectively. Exemplarily, the extending directions of the first and second wire-through holes are parallel to the first axis 100a, and the extending directions of the third and fourth wire-through holes are parallel to the third axis 100c.

[0102] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0103] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the embodiments of this application, the scope of which is defined by the appended claims and their equivalents.
