Description

Technical Field Figure 2

[0001] The utility model relates to the field of imaging devices, particularly to an imaging apparatus. Background Art

[0002] Known imaging devices usually have multiple degrees of freedom in order to cover a larger imaging range. For example, through the linkage of multiple motors, the camera of the imaging device can be driven at multiple angles, thereby increasing the imaging range that the imaging device can cover.

[0003] In known imaging devices, in order to achieve the linkage of multiple motors, usually one motor is placed on another motor. For example, one motor (such as a swing motor) drives the camera to swing, and another motor (a rotary motor) carries the swing motor and drives the swing motor to rotate, thereby achieving the linkage of the motors and driving the camera accordingly. The imaging device with this layout has a relatively high height in the height direction of the imaging device, and thus the overall height of the imaging device is relatively high. When the imaging device is used, for example, in pet monitoring, the imaging device with a relatively high height is likely to be knocked or bumped by pets. Summary of the Utility Model

[0004] In view of this, the utility model proposes an imaging device that can reduce the overall height.

[0005] The imaging device of the utility model includes: a rotary part, a swing part, and an actuator. The rotary part has a base and a rotary motor, the base is rotatably held, and the rotary motor is arranged on the first side of the base in a manner that enables the base to rotate when driven. The swing part is arranged on the first side of the base and rotates together with the base, and has a mounting bracket and a swing motor. The swing motor and the rotary motor are arranged in a flat and offset manner. The mounting bracket is driven by the swing motor to swing relative to the base. The actuator includes a camera, which is mounted to the end of the mounting bracket.

[0028] Reference Figures 1 to 13 and mainly refer to Figure 1 The camera device 100, used for monitoring pet behavior, is typically mounted in a suspended manner, such as on a wall or in a pet house. Specifically, this camera device 100 generally includes a base 101, a receiving portion 102 mounted on the base 101, and an actuator 103 extending from the receiving portion 102, including a camera 103a. Furthermore, the receiving portion 102 houses a rotary motor 202 for rotating the actuator 103 and a swing motor 203 for oscillating the actuator 103. The camera device 100 is mounted on the wall or in the pet house in a generally tilted position via the base 101. In this state, the receiving portion 102 and the actuator 103 are suspended laterally. The overall height of the receiving portion 102 and the actuator 103 from the base 101 is approximately equivalent to the overall length of the camera device 100 suspended laterally. When the dimensions of the housing 102 and the actuator 103 protruding excessively from the base 101, it can lead to an excessively long lever arm of the camera device 100's center of gravity relative to the horizontal direction of the point of application, potentially causing instability in the camera device 100. Furthermore, if the portion of the housing 102 and the actuator 103 protruding too far from the wall, it can easily attract the attention of pets, potentially causing them to bump into or touch the camera device 100. Therefore, it is necessary to reduce the overall height of the camera device 100.

[0029] Continue to refer to Figures 1 to 8The camera device 100 of the embodiment can be lowered in height overall. Specifically, the camera device 100 of the embodiment includes: a rotating part 200a, a swinging part 200b, and an actuator 103. The rotating part 200a has a base 201 and a rotating motor 202. The base 201 is rotatably held, and the rotating motor 202 is configured to rotate the base 201 in a driven state on a first side 201a of the base 201. The swinging part 200b is configured on the first side 201a of the base 201 and rotates together with the base 201. The swinging part 200b has a mounting bracket 250 and a swinging motor 203. The swinging motor 203 and the rotating motor 202 are laid flat and offset, and the mounting bracket 250 is driven by the swinging motor 203 to swing relative to the base 201. The actuator 103 includes a camera 103a, which is mounted to the end portion 250c of the mounting bracket 250.

[0030] The camera device 100 of this embodiment can be lowered in overall height. Specifically, in the camera device 100 of this embodiment, the rotary motor 202 can rotate the base 201 while in a driven state, thereby allowing the swing portion 200b disposed on the base 201 to rotate as a whole. Furthermore, since the actuator 103 is mounted to the mounting bracket 250 driven by the swing motor 203, the actuator 103 and the mounting bracket 250 are driven together by the swing motor 203 to swing relative to the base 201. Therefore, the camera device 100 as a whole can realize the rotation and / or swinging action of the actuator 103, thereby enabling the actuator 103 to cover a larger working range, for example, enabling the camera 103a to cover a larger imaging range.

[0031] Furthermore, in the camera device 100 of this embodiment, since the rotary motor 202 and the swing motor 203 are laid flat and misaligned on the same side (i.e., the first side 201a) of the base 201, it is possible to avoid the situation where one of the rotary motor 202 and the swing motor 203 is mounted on top of the other, thereby significantly reducing the height of the camera device 100. Therefore, the camera device 100 of this embodiment can reduce its overall height while allowing the camera 103a to cover a larger working range.

[0032] Continue to refer to Figures 1 to 3As described above, the camera device 100 includes a base 101, a receiving portion 102 mounted on the base 101, and an actuator 103 extending from the receiving portion 102. The base 101 can be fixed to various locations such as a wall or a pet house panel. The method of fixing the base 101 is not particularly limited; for example, it can be installed on a wall or panel by various methods such as threaded connection, adhesive tape, snap-fit, or magnetic adsorption. The receiving portion 102 includes a first housing 104 and a second housing 105 that cover each other, and the receiving portion 102 is fixed to the base 101 by the first housing 104. Similarly, the method of fixing the first housing 104 is not particularly limited; for example, it can be fixed to the base 101 by various methods such as threaded connection, adhesive tape, snap-fit, or magnetic adsorption. The rotating portion 200a is fixed to the first housing 104 in such a way that the base 201 can rotate relative to the first housing 104 (described later).

[0033] The second housing 105 is installed on the base 201 to cover the rotating part 200a and the swinging part 200b, and rotates relative to the first housing 104 as the base 201 rotates. The method of installing the second housing 105 on the base 201 is not particularly limited; for example, it can be installed on the base 201 by various methods such as threaded connection, adhesive tape bonding, snap-fit, or magnetic adsorption. The second housing 105 and the first housing 104 are coaxially fitted together; in other words, during rotation, the second housing 105 rotates around the axial centerline of the first housing 104.

[0034] On the side of the second housing 105 opposite to the first housing 104, a clearance groove 113 is formed, extending from the top 111 of the second housing 105 towards both sides. The clearance groove 113 is used to avoid the end portion 250c of the mounting bracket 250 of the swinging part 200b. The length of the clearance groove 113 is not particularly limited, as long as it is within the range that does not restrict the swing angle of the actuator 103. When closed with the first housing 104, the second housing 105 is mounted to the base 201 in such a way that the clearance groove 113 and the swing direction of the actuator 103 are aligned. Furthermore, the end portion 250c of the mounting bracket 250 protrudes from the clearance groove 113.

[0035] Therefore, when the camera 103a included in the actuator 103 is working, there are two actions when observing the camera device 100 from the outside: the second housing 105 rotates around the center of the first housing 104, and the mounting bracket 250 on which the actuator 103 is mounted swings within the clearance groove 113. Through these two actions, the camera device 100 can cover a larger imaging range.

[0036] The rotating part 200a of the camera device 100 will be described in more detail below.

[0037] Continue to refer to Figures 4 to 10 The base 201 of the rotating part 200a is generally circular in shape. The base 201 is mounted approximately coaxially to the first housing 104 and rotates relative to the first housing 104 with the center of rotation 201c at the center of the first housing 104. A first side 201a of the base 201, which houses the rotary motor 202 and the oscillating motor 203, is located on one side in the thickness direction and faces the second housing 105. Furthermore, the base 201 has a second side 201b located on the other side in the thickness direction (opposite to the first side 201a) and facing the first housing 104. A first mounting portion 205, coaxial with the rotation center 201c, is formed in the middle of the base 201. The first mounting portion 205 is circular in shape and extends axially from the first side 201a of the base 201 toward the second side 201b. A rotary bearing 206 is embedded in the first mounting portion 205, and the base 201 is rotatably mounted to the first housing 104 via the rotary bearing 206. More specifically, the first mounting portion 205 of the base 201 is rotatably mounted to the first transmission member 223 (described later) fixed to the first housing 104 via the rotary bearing 206. The depth of the first mounting portion 205, which is in the shape of a circular hole, is greater than the axial height of the rotary bearing 206. Although not particularly limited, the depth of the first mounting portion 205 can be 0.1 mm or more but less than 0.7 mm greater than the axial height of the rotary bearing 206. With the rotary bearing 206 housed in the first mounting portion 205, the end face of the rotary bearing 206 is slightly lower than the surface of the first side portion 201a.

[0038] The rotary bearing 206 is mounted to the first mounting portion 205 by fitting its outer diameter with the first mounting portion 205, which is in the shape of a circular hole. The rotary bearing 206 supports the rotation of the first mounting portion 205 and suppresses wear on the first mounting portion 205. The type of rotary bearing 206 is not particularly limited; for example, it can be a ring-shaped component made of copper alloy, stainless steel, wear-resistant resin material, etc.; in addition, it can also be a commercially available component with an outer ring, balls, and an inner ring, such as a deep groove ball bearing.

[0039] The base 201 has a plurality of first threaded holes 209 formed on its first side portion 201a. These first threaded holes 209 are spaced apart along the circumferential edge of the first mounting portion 205, which is shaped like a circular hole. There may be three or more first threaded holes 209. A plurality of first locking members 210 are detachably mounted on the first side portion 201a of the base 201 to hold the base 201 and the rotary bearing 206 axially relative to each other. The plurality of first locking members 210 are spaced apart circumferentially along the first mounting portion 205. Each first locking member 210 may be a bolt member having a threaded portion (not marked with reference numerals) and a head (not marked with reference numerals). The first locking members 210 are threadedly connected to the first threaded holes 209 of the base 201 via the threaded portion. When the first locking member 210 is locked into the first threaded hole 209, the edge of the head of the first locking member 210 extends axially above the first mounting portion 205, and extends beyond the edge of the first mounting portion 205. With the slewing bearing 206 housed in the first mounting portion 205, by locking the first locking member 210 into the first threaded hole 209, the head of the first locking member 210 can prevent the slewing bearing 206 from falling off at least one side of the base 201 along the axial direction. Thus, the base 201 and at least one side of the slewing bearing 206 along the axial direction are held together.

[0040] The base 201 has a generally annular wall portion 213 formed on the second side portion 201b, which protrudes axially from the second side portion 201b along the base 201. The wall portion 213 and the first mounting portion 205 are coaxial, and the first mounting portion 205, which is in the shape of a circular hole, extends axially from the base 201 to the wall portion 213. The thickness of the base 201 (i.e., the thickness between the first side portion 201a and the second side portion 201b) can be, for example, about 2 mm, and the protrusion height of the wall portion 213 can be, for example, about 4 mm. The depth of the first mounting portion 205 is, for example, about 4.5 mm. In other words, it can also be understood that the inner side of the wall portion 213 also defines a circular hole-shaped portion, and the circular hole-shaped portion on the inner side of the wall portion 213 and the circular hole-shaped first mounting portion 205 are integrally formed. This increases the depth of the first mounting portion 205. Furthermore, the first threaded hole 209 formed on the first side portion 201a of the base 201 also penetrates the wall portion 213 axially. This increases the depth of the first threaded hole 209.

[0041] A first limiting portion 214 is formed at the end of the wall portion 213 opposite to the second side portion 201b. A first through hole 215 is formed in the middle of the first limiting portion 214. The first through hole 215 and the first mounting portion 205 are coaxially connected, and the inner diameter of the first through hole 215 is smaller than the inner diameter of the circular mounting portion 205. Furthermore, the inner diameter of the first through hole 215 is larger than the inner diameter of the rotary bearing 206. The first limiting portion 214 can be formed around the entire circumference of the inner side of the wall portion 213. The first limiting portion 214 and the first locking member 210 are axially opposed to the rotary bearing 206 and restrict the rotary bearing 206.

[0042] The following describes how the rotary bearing 206 is mounted to the base 201.

[0043] First, a rotary bearing 206 is slid into a first mounting portion 205 in the shape of a circular hole on the first side portion 201a of the base 201, and one axial end of the rotary bearing 206 abuts against a first limiting portion 214 formed on the opposite end of the wall portion 213 and the second side portion 201b.

[0044] Then, each of the first locking members 210 is locked into the first threaded hole 209 from the first side portion 201a of the base 201. With the first locking member 210 locked into the first threaded hole 209, the edge of the head of the first locking member 210 extends axially above the first mounting portion 205.

[0045] Thus, the slewing bearing 206 is housed in the first mounting portion 205 and is axially restricted by the first locking member 210 and the first limiting portion 214. Therefore, the base 201 and the slewing bearing 206 are held together as a single unit.

[0046] Since the end face of the rotary bearing 206 is slightly lower than the surface of the first side portion 201a when the rotary bearing 206 is housed in the first mounting portion 205, even if the rotary bearing 206 is restricted axially by the first locking member 210 and the first limiting portion 214, the first mounting portion 205 can float slightly axially, thereby suppressing excessive friction between the first locking member 210 and the end face of the rotary bearing 206 when the base 201 rotates around the rotary bearing 206.

[0047] As described above, the rotary motor 202 is configured to rotate the base 201 in a driven state on the first side 201a of the base 201, and the swing motor 203 is configured on the first side 201a of the base 201, offset relative to the rotary motor 202. That is, the rotary motor 202 and the swing motor 203 are respectively configured on the first side 201a of the base 201 in a flat and offset manner, thereby reducing the overall height of the camera device 100, and the size of the base 201 can be appropriately increased accordingly. When the overall width of the camera device 100 increases and the height decreases, in addition to reducing the overall height of the camera device 100, the center of gravity of the camera device 100 also decreases further.

[0048] The rotary motor 202 has a first output shaft 216, which is parallel to the rotation center 201c of the base 201 and extends to a second side 201b of the base 201 opposite to the first side 201a. The type of rotary motor 202 is not particularly limited; for example, a known stepper motor can be used. The rotary motor 202 has a known motor configuration, for example, in addition to the output shaft (i.e., the first output shaft 216), the rotary motor 202 also has a main body (also referred to as "first main body 217" for distinction), a control box (also referred to as "first control box 218" for distinction), and wires extending from the control box (also referred to as "first wire 219" for distinction, for auxiliary reference). Figure 2 In the camera device 100 of the embodiment, the layout of each arrangement of the rotary motor 202 is adjusted to make the mounting positions of the rotary motor 202 and the swing motor 203, which are laid flat on the base 201, more compact. Specifically, the first output shaft 216 is located at one end of the axial direction of the first main body 217 and extends along the axial direction of the first main body 217. A mounting ear 220 is formed on each of the radial sides of the first main body 217. The first control box 218 is located on the outer periphery of the first main body 217 and is distributed at approximately 90° intervals along the outer periphery of the first main body 217 and the two mounting ears 220.

[0049] The rotary motor 202 is mounted directly to the base 201 in a vertical position. Specifically, the mounting lug 220 of the rotary motor 202 fits against the base 201 on one side of the first side portion 201a, and the rotary motor 202 is locked from the first side portion 201a by screws (not marked in the drawings). Furthermore, the rotary motor 202 is positioned radially on one side of the first mounting portion 205. More specifically, the rotary motor 202 is positioned radially on one side of the first mounting portion 205 such that the first output shaft 216 is offset from the rotation center 201c of the base 201. That is, the rotary motor 202 is mounted offset relative to the first mounting portion 205. In the locked state, the first output shaft 216 extends through a clearance hole (not marked in the drawings) formed in the base 201 to the second side portion 201b of the base 201. Additionally, the first control box 218 faces the center of the base 201, i.e., the side near the first mounting portion 205.

[0050] As described above, in the driving state, the rotary motor 202 causes the base 201 to rotate. Specifically, the rotating part 200a also includes a first transmission part 222, through which the rotary motor 202 causes the base 201 to rotate around the axis of the first mounting part 205, i.e., the rotation center 201c. That is, the first transmission part 222 causes the rotary motor 202 and the rotation center 201c of the first mounting part 205 of the base 201 to be misaligned. The first transmission part 222 is located on the second side 201b of the base 201, and more specifically, the first transmission part 222 is located in the space between the second side 201b of the base 201 and the first housing 104. One end of the first transmission part 222 is fixed and coaxial with the first mounting part 205, and the other end is connected to the first output shaft 216 of the rotary motor 202. When the rotary motor 202 is driven by the first transmission part 222, the first output shaft 216 of the rotary motor 202 rotates around one end of the first transmission part 222 which is in a fixed state. At the same time, the base 201, which is fixed to the rotary motor 202, also rotates around one end of the first transmission part 222.

[0051] The first transmission unit 222 includes a first transmission member 223, which is fixed and coaxial with the first mounting portion 205. The base 201 is rotatably held in the first transmission member 223 via the first mounting portion 205. Furthermore, the first transmission member 223 is locked to the first housing 104 by screws, thereby also rotatably holding the base 201 held in the first transmission member 223 relative to the first housing 104. The first transmission member 223 has a base 224, which is cylindrical and has an outer diameter smaller than the inner diameter of the first through hole 215 formed in the base 201. The first transmission member 223 may be a gear component, with teeth integrally formed around the outer periphery of the base 224. The first transmission member 223 has a second mounting portion 227 at one axial end adjacent to the base 201, which is coaxially formed with the base 224. The second mounting portion 227 is cylindrical, and its outer diameter is smaller than that of the base 224. The first mounting portion 205 and the second mounting portion 227 of the base 201 are coaxially mounted to the second mounting portion 227 and rotate freely. The slewing bearing 206 mounted on the first mounting portion 205 is also fitted onto the second mounting portion 227, and the base 201 is rotated freely onto the second mounting portion 227 via the slewing bearing 206 mounted on the first mounting portion 205. The first transmission member 223 has a plurality of second threaded holes 228 formed on the axial end face of the second mounting portion 227, and the second threaded holes 228 are distributed along the circumferential edge of the cylindrical second mounting portion 227. There may be more than three second threaded holes 228.

[0052] A plurality of second locking members 229 are detachably mounted on the axial end face of the first transmission member 223 and the second mounting portion 227. The second locking members 229 axially restrict the rotary bearing 206 so that the rotary bearing 206 is held in place by the first transmission member 223. The plurality of second locking members 229 are distributed circumferentially at intervals along the first transmission member 223. The second locking members 229 may be components with the same structure as the first locking member 210, i.e., the second locking member 229 is also a bolt member having a threaded portion (not marked with reference numerals) and a head (not marked with reference numerals). The second locking members 229 are threadedly connected to the threaded portion and the second threaded hole 228, and when the second locking member 229 is locked into the second threaded hole 228, the edge of the head of the second locking member 229 extends radially outward from the second mounting portion 227, thereby restricting the axial movement of the rotary bearing 206 relative to the second mounting portion 227. Thus, at least one side of the first transmission member 223 and the rotary bearing 206 are held in place by each other axially.

[0053] The first transmission member 223 has a second limiting portion 230 formed on one side of the second mounting portion 227 along the axial direction. The second limiting portion 230 is formed on the side where the base 224 and the second mounting portion 227 are adjacent along the axial direction. More specifically, the first transmission member 223 forms the second limiting portion 230 by making the outer diameter of the second mounting portion 227 smaller than the outer diameter of the base 224, thus forming a step at the junction of the base 224 and the second mounting portion 227. When the rotary bearing 206 is mounted to the second mounting portion 227, the rotary bearing 206 abuts against the second limiting portion 230. Furthermore, the second locking member 229 is mounted on the other side (end face) of the second mounting portion 227 along the axial direction, so that the second locking member 229 and the second limiting portion 230 are axially opposed to and hold the rotary bearing 206 apart.

[0054] The first transmission member 223 has a second through hole 231 extending along the axial direction, and the second through hole 231 and the second mounting portion 227 are coaxial. When the first transmission member 223 and the base 201 are mounted together, the second through hole 231 communicates with the first mounting portion 205, which is in the shape of a circular hole. More specifically, the second through hole 231 communicates with the first mounting portion 205, which is in the shape of a circular hole, through a first through hole 215 formed in the middle of the first limiting portion 214 of the base 201.

[0055] The first transmission unit 222 includes a second transmission member 232, which is coaxially mounted to the first output shaft 216 of the rotary motor 202 on the second side 201b and is connected to the first transmission member 223 in a transmission connection. The second transmission member 232 is also a gear component, and when mounted to the first output shaft 216 of the rotary motor 202, the second transmission member 232 and the first transmission member 223 engage with each other as gears.

[0056] Continue to refer to Figures 5 to 6 and supplementary reference Figure 7 The following describes the main steps for assembling the main components of the rotating part 200a. It should be noted that the installation steps described below are merely an example; other installation steps may also be used if installation is possible.

[0057] With the slewing bearing 206 installed on the base 201, the slewing bearing 206 is fitted onto the second mounting portion 227 of the first transmission member 223 and abuts against the second limiting portion 230 of the first transmission member 223.

[0058] Next, the second locking member 229 is locked into the second threaded hole 228, so that the second locking member 229 and the second limiting part 230 are axially opposed to and hold the rotary bearing 206 apart. With the rotary bearing 206 held in the first transmission member 223, the base 201 and the first transmission member 223 are held together as a whole.

[0059] Next, the rotary motor 202 is locked vertically to the first side 201a of the base 201 by screws. In the installed state of the rotary motor 202, the first output shaft 216 of the rotary motor 202 extends to the second side 201b, and the first control box 218 of the rotary motor 202 faces the side of the first mounting part 205.

[0060] Then, on the second side 201b of the base 201, while adjusting the meshing position of the second transmission member 232 and the first transmission member 223, the second transmission member 232 of the first transmission unit 222 is coaxially locked to the first output shaft 216 of the rotary motor 202 by screws. Thus, the base 201, the rotary motor 202, and the first transmission unit 222 become a whole.

[0061] Reference Figures 11 to 13 and supplementary reference Figures 5 to 10 The swinging part 200b of the camera device 100 will be described in more detail below.

[0062] As described above, the swinging part 200b is disposed on the first side 201a of the base 201 and rotates together with the base 201. Furthermore, the swing motor 203 is disposed on the first side 201a of the base 201 and is offset relative to the rotary motor 202. Additionally, the swing motor 203 is disposed on the opposite side of the first mounting part 205 in the radial direction relative to the rotary motor 202. The swinging part 200b has a mounting base 233, and the swinging part 200b is mounted to the base 201 via the mounting base 233. The swing motor 203 is mounted to the mounting base 233. In the installed state, the output shaft of the swing motor 203 (also referred to as "second output shaft 234" for easy distinction, see reference 234) is... Figure 8 The direction of the second output shaft 234 is orthogonal to the rotation center 201c of the base 201, and the second output shaft 234 is located on the first side 201a.

[0063] Mounting base 233 is mounted to base 201 on the first side 201a. Mounting base 233 is used to mount swing motor 203, mounting bracket 250, and second transmission part 246 (described later). Mounting base 233 has a first mounting base 233a and a support part 233b provided on the first mounting base 233a. The first mounting base 233a is mounted to base 201 as the main body, and the support part 233b is mainly used to support mounting bracket 250. The first mounting base 233a of mounting base 233 includes a first mounting wall 235 and a second mounting wall 236 that are spaced apart and opposite each other, and a connecting wall 237 that connects the first mounting wall 235 and the second mounting wall 236. The first mounting wall 235, the second mounting wall 236, and the connecting wall 237 are integrally formed and together define a space for accommodating swing motor 203 and rotary motor 202. With the swing motor 203 mounted on the mounting base 233, the first mounting wall 235 is located on one side of the second output shaft 234 of the swing motor 203, while the second mounting wall 236 is located on the opposite side of the swing motor 203 from the second output shaft 234.

[0064] The support portion 233b includes a first support shaft 238 and a second support shaft 239. The first support shaft 238 and the first mounting base 233a are integrally formed on one side of the first mounting base 233a. More specifically, the first support shaft 238 is formed on the outer side of the first mounting wall 235, and extends outward of the mounting base 233 along the direction in which the first mounting wall 235 and the second mounting wall 236 are opposite to each other. The way in which the first support shaft 238 and the first mounting wall 235 are integrally formed is not particularly limited; for example, the first support shaft 238 and the first mounting wall 235 can be integrally formed by injection molding, insert molding, or other methods. An axially extending threaded hole (not marked in the drawings) is formed at the end of the first support shaft 238 for axially locking the first swing bearing 260 and the mounting bracket 250 of the first support shaft 238. The second support shaft 239 and the first mounting base 233a are integrally formed on the other side of the first mounting base 233a. More specifically, the second support shaft 239 is formed on the outer side of the second mounting wall 236. The second support shaft 239 and the first support shaft 238 are coaxial and extend outward toward the mounting base 233. The manner in which the second support shaft 239 and the second mounting wall 236 are integrally formed is not particularly limited. For example, the second support shaft 239 and the second mounting wall 236 can be integrally formed by various methods such as injection molding or insert molding. The end of the second support shaft 239 has an axially extending threaded hole (not marked in the drawing), which is used for axially locking the second swing bearing 261 and the mounting bracket 250 mounted on the second support shaft 239. Furthermore, with the mounting base 233 installed on the base 201, the axes of the first support shaft 238 and the second support shaft 239 (i.e., the rotation center of the supported part 250b of the mounting bracket 250 relative to the support part 233b, which is also the swing center 247 of the swing part 200b) are orthogonal to and intersect with the rotation center 201c of the base 201 (i.e., the swing center 247 passes through the rotation center 201c of the base 201).

[0065] As described above, the mounting bracket 250 has a second mounting base 250a, a supported portion 250b, and an end portion 250c. The mounting bracket 250 can be made from a material that combines rigidity and elasticity. These materials are not particularly limited, but examples include: plastic materials such as polycarbonate (PC), polyamide (nylon, PA), polyoxymethylene (POM), polypropylene (PP), ABS (acrylonitrile-butadiene-styrene copolymer), polyetheretherketone (PEEK), thermoplastic polyurethane (TPU), polyphenylene sulfide (PPS), polyethylene terephthalate (PET), polytetrafluoroethylene (PTFE), and glass fiber (GF); and metallic materials such as stainless steel; etc. Furthermore, these materials can be used alone or in combination. For example, glass fiber (GF) can be added to polycarbonate (PC) to further improve the strength and rigidity of the mounting bracket 250 as mechanical properties.

[0066] The second mounting base 250a includes an integrally formed first arm 251, a second arm 252, and a connecting arm 253 connecting the first arm 251 and the second arm 252. The second mounting base 250a is generally U-shaped. The mounting bracket 250 is mounted to the mounting base 233 from the outside of the mounting base 233. With the mounting bracket 250 mounted to the mounting base 233, the first arm 251 and the second arm 252 of the second mounting base 250a are located on the outside of the first mounting base 233a along the axial direction of the support portion 233b (which can also be generally regarded as the direction in which the first mounting wall 235 and the second mounting wall 236 are opposite to each other), and the connecting arm 253 spans the first mounting base 233a along the axial direction of the support portion 233b. With the mounting bracket 250 installed on the mounting base 233, the first arm 251 and the first mounting wall 235 are opposite each other, the second arm 252 and the second mounting wall 236 are opposite each other, and the connecting arm 253 and the connecting wall 237 are opposite each other.

[0067] The supported portion 250b of the mounting bracket 250 is formed at one end (cantilever end) of the first arm portion 251 and the second arm portion 252. The supported portion 250b includes a first hole portion 262 and a second hole portion 263. The first hole portion 262 is formed at the cantilever end of the first arm portion 251, through which the first arm portion 251 is pivotally mounted on the first support shaft 238. The second hole portion 263 is formed at the cantilever end of the second arm portion 252, through which the second arm portion 252 is pivotally mounted on the second support shaft 239.

[0068] The end portion 250c of the mounting bracket 250 is formed at approximately the middle position along the length of the connecting arm 253, and the end portion 250c extends in the direction opposite to that of the first arm portion 251 and the second arm portion 252. Various known mounting structures for mounting the mounting box 254 of the actuator 103 can be formed on the end face of the end portion 250c, for example.

[0069] The mounting bracket 250 is oscillatingly mounted to the mounting base 233 such that the first hole 262 and the second hole 263 of the supported portion 250b rotate around the first support shaft 238 and the second support shaft 239 of the support portion 233b of the mounting base 233. Furthermore, a first oscillating bearing 260 is fitted between the first hole 262 and the first support shaft 238, and a second oscillating bearing 261 is fitted between the second hole 263 and the second support shaft 239. The type of oscillating bearing is not particularly limited; for example, it can be a ring-shaped component made of copper alloy, stainless steel, wear-resistant resin material, etc.; or it can be a commercially available component with an outer ring, balls, and an inner ring, such as a deep groove ball bearing.

[0070] With the first swing bearing 260 fitted between the first hole 262 and the first support shaft 238, it is locked to a threaded hole (not marked) formed in the first support shaft 238 by a screw. The screw and the limiting surface (not marked) on the first support shaft 238 used to restrict the first swing bearing 260 together fix the first swing bearing 260 axially. Similarly, with the second swing bearing 261 fitted between the second hole 263 and the second support shaft 239, it is locked to a threaded hole (not marked) formed in the second support shaft 239 by a screw. The screw and the limiting surface (not marked) on the second support shaft 239 used to restrict the second swing bearing 261 together fix the second swing bearing 261 axially. Furthermore, the first swing bearing 260 and the second swing bearing 261 together axially restrict the mounting bracket 250. Thus, when the mounting bracket 250 is mounted to the mounting base 233 via the first swing bearing 260 and the second swing bearing 261, the first arm 251 and the second arm 252 are respectively fixed axially relative to the first mounting base 233a, and the mounting bracket 250 swings freely relative to the mounting base 233 via the first swing bearing 260 and the second swing bearing 261.

[0071] The type of the swing motor 203 is not particularly limited. For example, the swing motor 203 can use the same configuration as the rotary motor 202, that is, in addition to the output shaft (i.e., the second output shaft 234), the swing motor 203 also has a main body (also referred to as "second main body 240" for distinction), a control box (also referred to as "second control box 241" for distinction), and wires leading out from the control box (also referred to as "second wires 242" for distinction). However, as described above, in the camera device 100 of the embodiment, in order to make the mounting positions of the rotary motor 202 and the swing motor 203 laid flat on the base 201 more compact, the layout of each configuration of the swing motor 203 is adjusted. Specifically, the second output shaft 234 is located at one end of the axial direction of the second main body 240 and extends along the axial direction of the second main body 240. The second control box 241 is located on the outer periphery of the second main body 240, and the swing motor 203 is mounted to the mounting base 233 with the second control box 241 facing the base 201, that is, facing the side opposite to the connecting wall 237 of the mounting base 233.

[0072] The oscillating motor 203 is arranged side-by-side with the rotary motor 202 on the radial side of the first mounting portion 205, with its second output shaft 234 and rotation center 201c offset. Furthermore, the axial extension direction of the second output shaft 234 is orthogonal to the direction in which the rotary motor 202 and the oscillating motor 203 are arranged side-by-side. In other words, as... Figure 8 As shown, with the mounting base 233 installed on the base 201, the second output shaft 234 of the swing motor 203 mounted on the mounting base 233 is misaligned relative to the rotation center 201c of the base 201. Furthermore, assuming a first dotted line 244 passes through the rotation center 201c of the base 201 and is orthogonal to the line of the rotation center 201c of the base 201, the swing motor 202 is configured such that, in a top view, the center line of the first output shaft 216 (also called the first center line 259) is parallel to the rotation center 201c and passes through the first dotted line 244, while the swing motor 203 is configured such that, in a top view, the second dotted line 245 passing through the center of its second main body 240 passes through the first dotted line 244. Furthermore, the second output shaft 234 of the swing motor 203 is configured such that, in a top-view perspective, the center line of the second output shaft 234 (here, the second dashed line 245) is orthogonal to the first dashed line 244.

[0073] The swing section 200b also includes a second transmission section 246 located on the first side section 201a, which is mounted to the mounting base 233. More specifically, the second transmission section 246 is mounted to the first mounting wall 235 of the first mounting base 233a of the mounting base 233. The second transmission section 246 drives the swing motor 203 and the mounting bracket 250 in such a way that the swing center 247 of the mounting bracket 250 and the rotation center 201c of the base 201 are orthogonal and intersecting (i.e., the swing center 247 of the mounting bracket 250 passes through the rotation center 201c of the base 201). Furthermore, the second transmission section 246 positions the swing motor 203 on one radial side of the support section 233b of the mounting base 233, and further on the other radial side of the first mounting section 205 of the base 201, opposite to the rotary motor 202 across the first mounting section 205. Additionally, the reduction ratio of the second transmission section 246 (transmission mechanism) is greater than 1 and less than 3. In other words, the swing speed of the mounting bracket 250 is less than the output speed of the swing motor 203.

[0074] The second transmission unit 246 includes a third transmission member 248 and a fourth transmission member 249, which may be gear components. The third transmission member 248 is coaxially fixed to the second output shaft 234 of the oscillating motor 203. Specifically, with the oscillating motor 203 mounted on the mounting base 233 and the second output shaft 234 of the oscillating motor 203 extending outside the first mounting wall 235 of the mounting base 233, the third transmission member 248 is mounted from outside the first mounting wall 235 of the mounting base 233 to the second output shaft 234 of the oscillating motor 203. The fourth transmission member 249 is coaxially fixed to the mounting bracket 250 along the oscillation center 247 of the mounting bracket 250. For example, the fourth transmission member 249 is fixed to the cantilever end of the first arm 251 of the mounting bracket 250 by screws. The fourth transmission member 249 is located between the first arm 251 of the mounting bracket 250 and the first mounting wall 235 of the mounting base 233, along the axial direction of the first support shaft 238.

[0075] Therefore, when the swing motor 203 is driven, the output force of the swing motor 203 is transmitted to the mounting bracket 250 via the third transmission member 248 and the fourth transmission member 249, thereby causing the mounting bracket 250 to swing relative to the mounting base 233, and thus driving the actuator 103 mounted on the mounting bracket 250.

[0076] Due to the transmission clearance between the third transmission member 248 and the fourth transmission member 249 of the second transmission unit 246, i.e., the transmission clearance between the gear components, the mounting bracket 250 does not stop immediately when the oscillating motor 203 stops, but continues to oscillate at a small angle due to gravity. Therefore, as described above, the oscillating unit 200b also includes a damping mechanism 300. The damping mechanism 300 is disposed between the mounting base 233 and the mounting bracket 250 and applies force to both the mounting base 233 and the mounting bracket 250 respectively, so that when the oscillating motor 203 stops, the mounting bracket 250 stops relative to the mounting base 233 at a preset position (i.e., the position where the mounting bracket 250 stops immediately when the oscillating motor 203 stops driving). Through this damping mechanism 300, without the driving force of the oscillating motor 203, the mounting bracket 250 and the mounting base 233 are kept stationary due to friction.

[0077] Continue to refer to Figure 12 as well as Figure 13 The following is a detailed description of the damping mechanism 300.

[0078] In some embodiments, the damping mechanism 300 is clamped between the mounting base 233 and the mounting bracket 250 in such a way that it applies force to the mounting base 233 and the mounting bracket 250 respectively in the direction of the rotation center (i.e., the swing center 247) of the supported portion 250b relative to the support portion 233b. The damping mechanism 300 may include a pad member 301, which may be clamped between the first arm portion 251 and the first mounting wall 235 of the first mounting base 233a along the axial direction of the first support shaft 238 (which is also the direction of the swing center 247), or the pad member 301 may be clamped between the second arm portion 252 and the second mounting wall 236 of the first mounting base 233a along the axial direction of the second support shaft 239 (which is also the direction of the swing center 247). It should be noted that multiple pad members 301 may be included and installed in multiple positions, for example, one of which is clamped between the first arm portion 251 and the first mounting wall 235, and another is clamped between the second arm portion 252 and the second mounting wall 236.

[0079] The configuration of the pad member 301 is not particularly limited as long as it can be sandwiched between the mounting base 233 and the mounting bracket 250. For example, the pad member 301 can be a separate component installed between the mounting base 233 and the mounting bracket 250; or, the pad member 301 can be an integral component formed with the mounting bracket 250 by, for example, insert molding; or, the pad member 301 can be an integral component formed with the mounting base 233 by, for example, insert molding.

[0080] The pad member 301 can be an elastic element, and the material forming the pad member 301 is not particularly limited. Examples include: rubbers such as natural rubber (NR), nitrile rubber (NBR), silicone rubber (VMQ), fluororubber (FKM), and ethylene propylene diene monomer (EPDM); polyurethane (PU); thermoplastic elastomers (TPE); and metals such as stainless steel and Q235A. When an elastic material such as rubber is selected as the pad member 301, the pad member 301 can be processed into a flat pad in the shape of a ring. When a rigid material such as a metal is selected as the pad member 301, the pad member 301 can be processed into a spring pad with an opening, or the pad member 301 can also be a compression type coil spring.

[0081] Furthermore, when an elastic material such as rubber is selected as the pad member 301, in order to allow the pad member 301 to be sufficiently compressed, the pad member 301 has a contact portion 302 and an abutment portion 303. The contact portion 302 is formed on one side of the pad member 301 and is planar. The abutment portion 303 is formed on the side of the pad member 301 opposite to the contact portion 302. The abutment portion 303 is formed to protrude along the axial direction of the pad member 301, surrounding the entire pad member 301. Additionally, an overflow space 304 is formed on one side of the abutment portion 303. The overflow space 304 is formed, for example, by making the radial length of the cross-section of the abutment portion 303 smaller than the difference between the outer diameter and the inner diameter of the pad member 301.

[0082] The following description uses an example where the pad member 301 is clamped between the second arm portion 252 and the second mounting wall 236 of the first mounting base portion 233a in a compressed state.

[0083] The pad member 301 is clamped in a compressed state between the second arm 252 and the second mounting wall 236 of the first mounting base 233a. The pad member 301 is made of natural rubber and is formed into a ring shape, which is fitted onto the second support shaft 239 located on the second mounting wall 236. When the second arm 252 of the mounting bracket 250 is axially mounted to the second support shaft 239 by screws, the second arm 252 and the second mounting wall 236 compress the pad member 301 axially. Because the pad member 301 is compressed, it also exerts an axial reaction force on the second arm 252 and the second mounting wall 236, thereby increasing the friction between the pad member 301 and the second arm 252, and also increasing the friction between the pad member 301 and the second mounting wall 236. Therefore, when the frictional forces are greater than or equal to the downward force acting on the mounting bracket 250 and the actuator 103 mounted on the end portion 250c of the mounting bracket 250 as a whole, the mounting bracket 250 is stably held relative to the mounting base 233 when the swing motor 203 does not output force on the mounting bracket 250.

[0084] With the pad member 301 sandwiched between the second arm portion 252 and the first mounting base 233a, the fitting portion 302 fits against one of the second arm portion 252 and the first mounting base 233a, while the abutting portion 303 abuts against the other of the second arm portion 252 and the second mounting base 250a and is compressed, overflowing into the overflow space 304. For example, the fitting portion 302 of the pad member 301 abuts against the second mounting wall 236, while the abutting portion 303 of the pad member 301 is opposite to the second arm portion 252. When the mounting bracket 250 is installed onto the mounting base 233, the second arm portion 252, along the axial direction of the second support shaft 239, faces the second mounting wall 236, abutting against and compressing the abutting portion 303. After being compressed, the abutting portion 303 remains in contact with the second arm portion 252 while overflowing into the overflow space 304. Thus, while fully compressing the pad member 301, the contact area between the pad member 301 and the second arm portion 252 is increased. It should be noted that when the pad member 301 is made of an elastic material such as rubber, the contact portion 302 is actually compressed together with the abutment portion 303.

[0085] Furthermore, when it is necessary to increase or decrease the compression degree of the pad member 301 to increase or decrease the friction between the mounting base 233 and the mounting bracket 250, the thickness of the pad member 301 can be increased or decreased while keeping the distance between the second arm 252 and the second mounting wall 236 along the axial direction of the second support shaft 239 constant, or the number of adjusting shims (not shown) can be increased or decreased if they are present. Alternatively, the distance between the second arm 252 and the second mounting wall 236 along the axial direction of the second support shaft 239 can be decreased in various ways. In addition, when it is necessary to increase or decrease the friction between the mounting base 233 and the mounting bracket 250, the pad member 301 can be added between the first arm 251 and the first mounting wall 235, or the pad member 301 between the first arm 251 and the first mounting wall 235 can be removed.

[0086] Therefore, by providing a damping mechanism 300 that is clamped between the mounting base 233 and the mounting bracket 250 in a manner that applies force to the mounting base 233 and the mounting bracket 250 respectively along the swing center 247, the mounting bracket 250 can be more stably maintained in the preset position of the mounting base 233. For example, refer to Figure 7 At the instant the swing motor 203 stops driving the mounting bracket 250 to a position where the first arm 251 and the rotation center 201c are parallel, the mounting bracket 250 also immediately stops and remains in the position where the first arm 251 is parallel to the rotation center 201c, and will not shift relative to the rotation center 201c due to the transmission backlash of the second transmission part 246. (Continue referring to...) Figures 1 to 13The following describes the main steps for assembling the main components of the swing unit 200b. It should be noted that the installation steps described below are merely an example; other installation steps may also be used if installation is possible.

[0087] The oscillating motor 203 is placed within the space defined by the first mounting wall 235, the second mounting wall 236, and the connecting wall 237 of the mounting base 233, such that the second output shaft 234 of the oscillating motor 203 extends outward from the outside of the first mounting wall 235, and the oscillating motor 203 is locked inside the first mounting wall 235. At this time, the second output shaft 234 is parallel to the directions of the first mounting wall 235 and the second mounting wall 236, and the second control box 241 faces the side of the base 201.

[0088] Next, on the first mounting wall 235 side of the mounting base 233, the third transmission member 248 of the second transmission unit 246 is coaxially locked to the second output shaft 234 of the swing motor 203. Then, while adjusting the meshing position of the third transmission member 248 and the fourth transmission member 249, the fourth transmission member 249 is fitted into the first support shaft 238.

[0089] Then, on the second mounting wall 236 side of the mounting base 233, the pad member 301 of the damping mechanism 300 is fitted into the second support shaft 239.

[0090] Next, the first arm 251 and the second arm 252 of the mounting bracket 250 are expanded outward in opposite directions, and the first arm 251 is mounted on the first support shaft 238, and the second arm 252 is mounted into the second support shaft 239.

[0091] Then, the first swing bearing 260 is fitted between the first hole 262 and the first support shaft 238, and the second swing bearing 261 is fitted between the second hole and the second support shaft 239.

[0092] Then, the first swing bearing 260 and the second swing bearing 261 are locked with screws. In addition, the first arm 251 and the fourth transmission member 249 are locked.

[0093] Thus, the swing motor 203, mounting base 233, mounting bracket 250, second transmission unit 246, and damping mechanism 300 become a whole.

[0094] Continue to refer to Figures 1 to 3Additionally, the actuator 103 of the camera device 100 includes a mounting box 254, which is mounted to the end portion 250c of the mounting bracket 250. The camera 103a of the actuator 103 is housed within the mounting box 254. Furthermore, the actuator 103 may also include other electrical components (e.g., various components for controlling the camera 103a). The mounting box 254 is also provided with a cover plate 264, which is slidable relative to the mounting box 254 to expose or cover the camera 103a. The cover plate 264 can be slidably mounted to the mounting box 254, for example, via a guide rail (not marked in the drawings).

[0095] The camera device 100 also includes a control unit 255, which includes a control plate 256 mounted on a first side 201a of the base 201. More specifically, the control plate 256 is mounted on one side of the second mounting wall 236 of the mounting base 233. The control plate 256 is mounted such that its length is along the direction in which the rotary motor 202 and the oscillating motor 203 are aligned, and its width is along the direction of the rotation center 201c of the base 201. In other words, the thickness direction of the control plate 256 is parallel to the axial direction of the second output shaft 234. Furthermore, the assembly method of the control plate 256 is not particularly limited; for example, the control plate 256 can be snapped onto the base 201.

[0096] The control unit 255 also includes multiple wires, among which at least the first wire 219, the second wire 242, the third wire 257, and the fourth wire 258 are mentioned above. The first wire 219 serves as the control line for the rotary motor 202, with one end connected to the first control box 218 of the rotary motor 202 (see reference). Figure 9The first wire 242 serves as the control line for the swing motor 203, with one end connected to the side of the second control box 241 of the swing motor 203 opposite to the control board 256, and the other end connected to the control board 256. The third wire 257 serves as the control line for the overall electrical connection between the camera device 100 and the external environment, connecting from the second side 201b of the base 201 via the second through hole 231 and the first mounting portion 205 in the shape of a circular hole to the control board 256. More specifically, the third wire 257 connects to the control board 256 from the power interface and / or signal transmission interface on the side of the side wall 107 of the first housing 104, via the second through hole 231 of the first transmission member 223, the first through hole 215 of the base 201, the first mounting portion 205 in the shape of a circular hole, and through the first side 201a of the first housing 104. The fourth wire 258 serves as the wire electrically connected to the control board 256 of the actuator 103. One end is connected to the actuator 103 mounted on the mounting bracket 250, and the other end is connected to the control board 256 via the second arm 252. More specifically, the fourth wire 258 passes through the mounting box 254 and the connecting arm 253 of the mounting bracket 250 and connects to the control board 256 along the second arm 252.

[0097] Next, the main steps of assembling the camera device 100 as a whole will be explained. It should be noted that the installation steps described below are only an example, and other installation steps may also be used as long as installation is possible.

[0098] First, the swing section 200b, which mainly includes the swing motor 203, mounting base 233, mounting bracket 250, second transmission section 246, and damping mechanism 300, is mounted to the rotary section 200a, which includes the base 201, rotary motor 202, and first transmission section 222. That is, the mounting base 233 is locked to the base 201 with screws. Next, the clearance groove 113 of the second housing 105 is aligned with the end portion 250c formed in the middle of the connecting arm 253 of the mounting bracket 250, so that the end portion 250c protrudes from the clearance groove 113, and the second housing 105 covers the base 201. Then, the second housing 105 and the base 201 are locked together from the second side 201b side of the base 201 with screws.

[0099] Then, the first housing 104 and the first transmission member 223 are locked, thereby locking the first housing 104 and the second housing 105 together. Next, the mounting box 254 of the actuator 103 is locked to the end portion 250c of the mounting bracket 250 that exposes the second housing 105. In addition, when mounting the box 254, the magnitude of the friction force of the damping mechanism 300 can be adjusted to ensure that the actuator 103 can be stably held. Finally, the base 101 is installed onto the first housing 104 by means of a snap-fit, thereby completing the assembly of the camera device 100.

[0100] In the camera device 100 of this embodiment, since the rotary motor 202 and the swing motor 203 are laid flat and misaligned on the same side (i.e., the first side 201a) of the base 201, it is possible to avoid the situation where one of the rotary motor 202 and the swing motor 203 is mounted on top of the other, thereby significantly reducing the height of the camera device 100. Therefore, the camera device 100 of this embodiment can reduce the overall height while allowing the camera 103a to cover a larger working range.

[0101] In the embodiment of the camera device 100, the first output shaft 216 is parallel to the rotation center 201c of the base 201 and extends to the second side 201b of the base 201 opposite to the first side 201a. Thus, even when the overall height of the camera device 100 is reduced and made more compact, the first transmission unit 222 can be installed more easily on the second side 201b opposite to the first side 201a where the rotary motor 202 and the swing motor 203 are installed, and the rotation of the base 201 can be achieved by a transmission structure that uses two simple spur gear components for transmission.

[0102] In the imaging device 100 of the embodiment, the second output shaft 234 and the rotation center 201c of the base 201 are orthogonal in direction, and the second output shaft 234 is located on the first side 201a. Therefore, even when the overall height of the imaging device 100 is reduced and made more compact, the swinging part 200b can be mounted more easily on the first side 201a of the base 201. Furthermore, the axial extension direction of the second output shaft 234 is orthogonal to the direction in which the rotary motor 202 and the swinging motor 203 are parallel. Therefore, the second transmission part 246 mounted on the second output shaft 234 can be more easily configured, and the swinging of the mounting bracket 250 relative to the rotation center 201c of the base 201 can be realized by a transmission structure that uses two simple spur gear members for transmission.

[0103] In the camera device 100 of the embodiment, by configuring the first transmission unit 222 and the second transmission unit 246, the rotary motor 202 and the swing motor 203 are respectively arranged on both sides of the first mounting part 205 and the support part 233b in the radial direction. This allows for a more compact arrangement of the rotary motor 202 and the swing motor 203. Furthermore, by configuring the camera device 100 with the rotation center 201c and the swing center 247 orthogonal and intersecting through the first transmission unit 222 and the second transmission unit 246, the rotation and swing movements of the camera device 100 can be balanced and superimposed, thereby improving the control accuracy of the camera device 100 and reducing the control difficulty of the camera device 100.

[0104] In the imaging device 100 of the embodiment, by fixing the first transmission member 223 to the first housing 104, and holding the base 201 coaxially and rotatably on the first transmission member 223, the base 201 can be held using the structure of the first transmission part 222 itself, which can further reduce the height of the imaging device 100 and make the structure of the imaging device 100 more compact. Furthermore, by using a gear member, the center distance of the first transmission part 222 can be shortened, making the structure of the imaging device 100 even more compact.

[0105] In the camera device 100 of the embodiment, by mounting the first mounting portion 205 of the base 201 to the second mounting portion 227 of the first transmission member 223 via the rotary bearing 206, the base 201 can rotate more smoothly relative to the first transmission member 223, and the wear of the base 201 and / or the first transmission member 223 can be reduced.

[0106] In the imaging device 100 of the embodiment, the first mounting portion 205, which is in the shape of a circular hole, extends along the direction of the rotation center 201c of the base 201 to the wall portion 213 formed on the second side portion 201b. This increases the depth of the first mounting portion 205, thereby appropriately increasing the height of the rotating bearing 206, thereby improving the reliability of the rotation of the base 201 and suppressing the shaking of the base 201 during rotation.

[0107] In the imaging device 100 of the embodiment, a first locking member 210 is detachably mounted on the first side portion 201a to hold the base 201 and the rotary bearing 206 axially relative to each other, and a first limiting portion 214 is formed on the wall portion 213. The first locking member 210 and the first limiting portion 214 are axially spaced apart from and restrict the rotary bearing 206, thereby reliably holding the base 201 and the rotary bearing 206 relative to each other. Furthermore, since the detachable first locking member 210 is used, it is also possible to suppress the increase in the overall height of the imaging device 100. For example, by reducing the thickness of the head of the first locking member 210 as much as possible, the superimposed size of the first locking member 210 and the rotary motor 202 or the swing motor 203 in the height direction can be reduced, thereby suppressing the increase in the overall height of the imaging device 100.

[0108] In the camera device 100 of the embodiment, a first through hole 215 is formed in the middle of the first limiting part 214 of the base 201, and a second through hole 231 is formed in the first transmission member 223. As a result, the third wire 257, which serves as the wire for electrical connection between the camera device 100 as a whole and the outside, can be connected to the control board 256 via the vicinity of the rotation center 201c of the base 201, and the situation where the third wire 257 becomes entangled as the base 201 rotates is suppressed.

[0109] In the imaging device 100 of the embodiment, a second locking member 229 is detachably mounted on the first transmission member 223. The second locking member 229 and the second mounting portion 227 formed on the first transmission member 223 are axially spaced apart from and restrict the rotation bearing 206, thereby reliably holding the first transmission member 223 and the rotation bearing 206 together. Furthermore, since the detachable second locking member 229 is used, an increase in the overall height of the imaging device 100 can be suppressed. For example, by minimizing the thickness of the head of the second locking member 229, the superimposed dimensions of the second locking member 229 and the rotary motor 202 or the swing motor 203 in the height direction can be reduced, thereby suppressing an increase in the overall height of the imaging device 100.

[0110] In the camera device 100 of the embodiment, the swing unit 200b further includes a mounting base 233. The mounting base 233 is mounted to the base 201 on the first side 201a. The swing motor 203 and the second transmission unit 246 are mounted to the mounting base 233 and are also mounted to the base 201 via the mounting base 233. This strengthens the overall strength of the camera device 100. Furthermore, modular installation of the camera device 100 is possible, the installation steps of the camera device 100 are refined, and the installation difficulty of the camera device 100 is reduced.

[0111] In the camera device 100 of the embodiment, by having the mounting bracket 250 have a first arm 251 and a second arm 252, when the mounting bracket 250 is mounted to the mounting base 233, the first arm 251 and the second arm 252 are located on the outside of the first mounting base 233a of the mounting base 233 along the axial direction of the support portion 233b (i.e., the direction of the swing center 247 of the mounting bracket 250), so that the mounting bracket 250 can be stably and reliably mounted on the mounting base 233 in a manner that clamps the mounting base 233.

[0112] In the camera device 100 of this embodiment, by making the support portion 233b of the mounting base 233 include a first support shaft 238 and a second support shaft 239, and the supported portion 250b of the mounting bracket 250 includes a first hole portion 262 mounted on the first support shaft 238 and a second hole portion 263 mounted on the second support shaft 239, the mounting bracket 250 can be easily installed into the mounting base 233 by deformation, and the mounting bracket 250 can swing smoothly and stably relative to the mounting base 233.

[0113] Furthermore, by clamping the pad member 301 included in the damping mechanism 300 between the mounting base 233 and the mounting bracket 250 such that it applies force to the mounting base 233 and the mounting bracket 250 respectively along the axial direction of the support portion 233b, the damping mechanism 300 can be easily configured. For example, since the damping mechanism 300 is clamped between the mounting base 233 and the mounting bracket 250, the magnitude of the frictional force generated by the damping mechanism 300 can be changed simply by changing the clamping force between the mounting base 233 and the mounting bracket. This makes it easy to adjust the damping mechanism 300, and the required magnitude of the frictional force can be determined through limited testing, further facilitating implementation.

[0114] Furthermore, since the damping mechanism 300 is arranged axially along the support portion 233b, it will not affect the swinging action or swing accuracy of the mounting bracket 250.

[0115] Furthermore, by clamping the pad member 301 between the first arm portion 251 and the first mounting base 233a, and / or between the second arm portion 252 and the first mounting base 233a, along the axial direction of the support portion 233b, the pad member 301 can be installed or replaced more easily and at a lower cost. In addition, since the pad member 301 is close to the swing center of the mounting bracket 250, the mounting bracket 250 can swing smoothly while maintaining the friction between the mounting bracket 250 and the mounting base 233, thus suppressing jamming of the mounting bracket 250 as a whole.

[0116] In the camera device 100 of the embodiment, by fixing the first arm 251 and the second arm 252 axially relative to the first mounting base 233a, the mounting bracket 250 and the mounting seat 233 can clamp the pad member 301 with a substantially constant clamping force, thereby ensuring that the frictional force generated by the damping mechanism 300 between the mounting bracket 250 and the mounting seat 233 is substantially constant, and ensuring that the mounting bracket 250 is reliably held in a preset position without the driving force of the swing motor 203.

[0117] In the camera device 100 of the embodiment, the control board 256 is mounted on the first side 201a of the base 201, and is mounted with its length along the direction in which the rotary motor 202 and the swing motor 203 are parallel, and its width along the direction of the rotation center 201c of the base 201. As a result, the routing of the first wire 219, the second wire 242, the third wire 257 and the fourth wire 258 can be easily arranged, and the installation space required for the control board 256 can be reduced.

[0118] Furthermore, in the above embodiment, the first transmission unit 222 is described as including a first transmission member 223 and a second transmission member 232, which are gear components, but it is not limited thereto. For example, the first transmission member 223 and the second transmission member 232 may also be synchronous pulleys or belt pulleys. In addition, the first transmission unit 222 is not limited to the first transmission member 223 and the second transmission member 232, and may also have other intermediate transmission members.

[0119] In the above embodiment, the first output shaft 216 of the rotary motor 202 and the rotation center 201c of the base 201 are misaligned and connected via the first transmission part 222, but this is not a limitation. For example, the rotary motor 202 can also be mounted to the base 201 in a manner where the first output shaft 216 and the rotation center 201c of the base 201 are coaxial. In this manner, for example, the output shaft of the rotary motor 202 can be directly fixed to the first housing 104 without the need to add the first transmission part 222.

[0120] In the above embodiment, an example was described where the first mounting portion 205 of the base 201 is in the shape of a circular hole, and the second mounting portion 227 is in the shape of a cylinder; however, this is not a limitation. For example, the first mounting portion 205 may also be cylindrical, and correspondingly, the second mounting portion 227 may be in the shape of a circular hole, with the rotary bearing 206 housed in the second mounting portion 227, and the first mounting portion 205 inserted into the rotary bearing 206. This allows the base 201 to rotate relative to the first transmission member 223. Furthermore, although an example with a rotary bearing 206 between the first mounting portion 205 and the second mounting portion 227 was described, this is not a limitation. In fact, as long as the base 201 and the first transmission member 223 are formed of a sufficiently wear-resistant material, the rotary bearing 206 may not be present between the first mounting portion 205 and the second mounting portion 227.

[0121] In the above embodiment, an example was described in which a plurality of first locking members 210 are detachably mounted on the first side portion 201a of the base 201, and the first locking members 210 and the first limiting portion 214 are axially spaced relative to and limit the rotary bearing 206. However, this is not a limitation. For example, the base 201 may not form the first limiting portion 214 on the second side portion 201b, but instead, a plurality of first locking members 210 may be detachably mounted on the second side portion 201b, and the rotary bearing 206 may be jointly limited by the first locking members 210 located on both sides of the base 201. Furthermore, although an example of using bolts as first locking members 210 was described, this is not a limitation. For example, retaining rings may also be used as first locking members 210.

[0122] In the above embodiment, an example was described in which a second limiting portion 230 is formed on one axial side of the second mounting portion 227 of the first transmission member 223, and a plurality of second locking members 229 are detachably mounted on the other axial side, with the second locking members 229 and the second limiting portion 230 jointly limiting the rotary bearing 206. However, this is not a limitation. For example, the second limiting portion 230 may not be formed on one axial side of the second mounting portion 227 of the first transmission member 223, but the second locking members 229 may be detachably mounted in the same manner, and the rotary bearing 206 may be jointly limited by the second locking members 229 located on both axial sides of the second mounting portion 227. Furthermore, although an example of using a bolt as the second locking member 229 was described, this is not a limitation. For example, a retaining ring may also be used as the second locking member 229.

[0123] In the above embodiment, an example was described whereby the swing motor 203 is mounted to the mounting base 233 and then to the base 201 via the mounting base 233, but this is not a limitation. For example, the camera device 100 may not have the mounting base 233, but instead have the first mounting wall 235 and the second mounting wall 236 of the mounting base 233 integrally formed with the base 201, and the swing motor 203, the second transmission part 246, and the mounting bracket 250, etc., are mounted on the base 201.

[0124] In the above embodiment, the second transmission unit 246 is described as including a third transmission member 248 and a fourth transmission member 249 of gear components, but it is not limited thereto. For example, the third transmission member 248 and the fourth transmission member 249 may also be a synchronous pulley or a belt pulley. Furthermore, the second transmission unit 246 is not limited to the third transmission member 248 and the fourth transmission member 249, and may also have other intermediate transmission members.

[0125] In the above embodiment, an example was described in which the second transmission unit 246 connects the swing motor 203 and the mounting bracket 250 such that the swing center 247 of the actuator 103 is orthogonal to the rotation center 201c of the base 201, and the swing center 247 of the actuator 103 passes through the rotation center 201c of the base 201. However, this is not a limitation. For example, the swing motor 203 may be directly positioned at a position where the second output shaft 234 is orthogonal to and intersects with the rotation center 201c of the base 201 (passing through the rotation center 201c of the base 201). In this case, the second transmission unit 246 may be omitted, and the mounting bracket 250 may be directly mounted to the second output shaft 234 of the swing motor 203.

[0126] In the above embodiment, although an example has been described in which the mounting bracket 250 has a first arm 251 and a second arm 252, and the first arm 251 and the second arm 252 are located outside the mounting base 233, it is not limited to this. For example, the mounting base 233 may be U-shaped in general, and the mounting bracket 250 may be mounted inside the mounting base 233.

[0127] In the above embodiments, although an example has been described where the support portion 233b includes a first support shaft 238 and a second support shaft 239, and the supported portion 250b includes a first hole 262 and a second hole 263, the embodiments are not limited thereto. For example, the support portion 233b of the mounting base 233 may include a first hole 262 and a second hole 263, while the supported portion 250b of the mounting bracket 250 may include a first support shaft 238 and a second support shaft 239.

[0128] Furthermore, while the above embodiments illustrate an example of the first mounting base 233a and the support portion 233b being integrally formed, the embodiments are not limited thereto. When the support portion 233b includes a first support shaft 238 and a second support shaft 239, the first support shaft 238 and the second support shaft 239 can also be mounted to the first mounting base 233a as separate components. Alternatively, the first support shaft 238 and the second support shaft 239 can be a single, integral long shaft spanning the entire first mounting base 233a.

[0129] Similarly, when the supported portion 250b of the mounting bracket 250 includes a first support shaft 238 and a second support shaft 239, the first support shaft 238 and the second support shaft 239 can be integrally formed with the second mounting base 250a of the mounting bracket 250, or they can be installed as separate components on the first mounting base 233a.

[0130] In the above embodiments, although examples have been described where the pad member 301 is sandwiched between the first arm 251 and the first mounting base 233a along the axial direction of the support portion 233b, and / or between the second arm 252 and the first mounting base 233a, the embodiments are not limited thereto. For example, when the mounting bracket 250 has a connecting arm 253 that spans the first mounting base 233a of the mounting seat 233 along the axial direction of the support portion 233b, the damping mechanism 300 may also be sandwiched between the connecting arm 253 and the first mounting base 233a, and apply force to the connecting arm 253 and the first mounting base 233a respectively. Furthermore, the pad member 301 may be disposed separately between the connecting wall 237 of the connecting arm 253 and the first mounting base 233a, or it may be used with the pad member 301 between the first arm 251 and the first mounting base 233a, and / or between the second arm 252 and the first mounting base 233a.

[0131] In the above embodiment, although the pad member 301 of the damping mechanism 300 is described as an example of an elastic element, it is not limited thereto. For example, the pad member 301 may also have a friction surface formed on its surface, such as knurling, and be sandwiched between the mounting bracket 250 and the mounting base 233.

[0132] Furthermore, while the above embodiments illustrate an example of using the camera device 100 for pet monitoring, it is not limited to this. The camera device 100 can also be used in various applications such as dashcams, home surveillance equipment, and outdoor surveillance equipment.

[0133] Although embodiments of this implementation have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this implementation, the scope of which is defined by the claims and their equivalents.
