Detailed Implementation

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0029] The reference to "embodiment" in this application means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0030] Furthermore, the technical solutions of the various embodiments can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0031] This application describes a monitoring device that limits the rotation angle. This monitoring device can be used for video surveillance, and also for other scenarios requiring video recording. It can also be connected to electronic devices such as computers, mobile phones, and servers via wired and / or wireless and / or network connections, enabling the electronic devices to store and play videos.

[0032] Please see Figure 1 , Figure 1This is a schematic diagram of the structure of a monitoring device for limiting rotation angle in some embodiments of this application. The monitoring device 100 for limiting rotation angle may include a mounting frame 101, a camera module 102, and a solar panel 103. The mounting frame 101 can be used to support the structure in which the monitoring device 100 for limiting rotation angle is installed, and can be installed on environmental objects such as columns, utility poles, piles, walls, frames, mountains, and rock formations. The specific environmental object can be selected or adjusted according to the needs of those skilled in the art, as long as it can accommodate the monitoring device 100 for limiting rotation angle, and is not limited thereto. The camera module 102 can be installed on the mounting frame 101 for video recording. Of course, in some embodiments, the camera module 102 may not be installed on the mounting frame 101, but on other structures or used directly alone. The solar panel 103 can be installed on the mounting frame 101 to generate electricity using sunlight. Of course, in some embodiments, the solar panel 103 may not be installed on the mounting frame 101, but on other structures or directly on environmental objects. The solar panel 103 can be electrically connected to the camera module 102, thereby powering the camera module 102. It is understood that in some embodiments, the camera module 102 may not be powered by the solar panel 103, but rather by a built-in power supply or an external power supply. Furthermore, in some embodiments, the solar panel 103 may be omitted.

[0033] In some embodiments, the solar panel 103 may be positioned vertically above the camera module 102, thereby ensuring that the camera module 102 does not block sunlight from shining on the solar panel 103, thus improving the power generation efficiency of the solar panel 103. In some embodiments, the vertical projection of the solar panel 103 may be at least partially located on the camera module 102, thereby shielding the camera module 102 from falling objects such as raindrops and debris, ensuring the safety of the camera module 102.

[0034] The mounting bracket 101 may be a frame structure, a linkage structure, a base structure, or other structures well known to those skilled in the art, which will not be described in detail.

[0035] Please see Figure 1The mounting bracket 101 may include a fixing base 10, a mounting component 20, and an assembly component 30. The fixing base 10 can be installed on an environmental object via screwing, snap-fitting, welding, plugging, binding, or other installation methods well known to those skilled in the art, which will not be elaborated further. The mounting component 20 may be disposed on the fixing base 10 for mounting the camera module 102. Of course, in some embodiments, the camera module 102 may also be directly disposed on the fixing base 10 without being disposed on the mounting component 20. The assembly component 30 may be disposed on the fixing base 10 for mounting the solar panel 103. Of course, in some embodiments, the solar panel 103 may also be directly disposed on the fixing base 10 without being disposed on the assembly component 30. In some embodiments, the mounting component 20 or the assembly component 30 may be omitted. In some embodiments, there may be two fixing bases 10, one for mounting the mounting component 20 and one for mounting the assembly component 30.

[0036] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 2 for Figure 1 The illustrated embodiment shows a schematic diagram of the structure of the fixing base 10 in some embodiments. Figure 3 for Figure 2 The illustrated embodiment shows a sectional view of the fixing base 10 along line III-III. Figure 4 for Figure 2 The schematic diagram of the fixing base 10 in the embodiment shown is from another perspective. Figure 5 for Figure 4 The illustrated embodiment shows a cross-sectional view of the fixing base 10 along line VV. The fixing base 10 may include a fixing body 11. The fixing body 11 may be a plate-like structure, a block-like structure, a frame structure, or other shapes and structures, etc., which will not be described in detail.

[0037] The fixing base 10, such as the fixing body 11, may have a first surface 111, a second surface 112, and a side surface 113. The first surface 111 and the second surface 112 are disposed on opposite sides of the fixing base 10, such as the fixing body 11. The side surface 113 may surround the fixing base 10, such as the fixing body 11, and may connect to the first surface 111 and the second surface 112, thereby cooperating with the first surface 111 and the second surface 112 as at least a portion of the outer surface of the fixing base 10, such as the fixing body 11. In some embodiments, the first surface 111 and the second surface 112 may be disposed on opposite sides of the fixing base 10, such as the fixing body 11, in a horizontal direction.

[0038] In some embodiments, the side surface 113 may include a first side surface 1131, a second side surface 1132, a third side surface 1133, and a fourth side surface 1134. In some embodiments, the first side surface 1131 and the second side surface 1132 may be disposed on opposite sides of the fixing base 10, such as the fixing body 11. In some embodiments, the first side surface 1131 and the second side surface 1132 may be disposed on opposite sides of the fixing base 10, such as the fixing body 11, in a vertical direction. In some embodiments, the third side surface 1133 and the fourth side surface 1134 may be disposed on opposite sides of the fixing base 10, such as the fixing body 11. In some embodiments, the third side surface 1133 and the fourth side surface 1134 may be disposed on opposite sides of the fixing base 10, such as the fixing body 11, in a horizontal direction. In some embodiments, the first side surface 1131, the third side surface 1133, the second side surface 1132, and the fourth side surface 1134 may be connected sequentially. In some embodiments, the first side surface 1131 is connected to the first surface 111 and the second surface 112. In some embodiments, the second side surface 1132 may be connected to the first surface 111 and the second surface 112. In some embodiments, the third side surface 1133 may be connected to the first surface 111 and the second surface 112. In some embodiments, the fourth side surface 1134 may be connected to the first surface 111 and the second surface 112.

[0039] In some embodiments, the fixing base 10, such as the fixing body 11, may be provided with a first fixing part 12. The first fixing part 12 can be installed on the environmental object by screwing, snapping, welding, plugging, binding, or other installation methods well known to those skilled in the art, which will not be elaborated further. Thus, the first fixing part 12 can realize the installation of the fixing base 10, such as the fixing body 11, on the environmental object. In some embodiments, the first fixing part 12 may be provided with a first fixing hole 1201 located on the first surface 111, so that a connector can be passed through the first fixing hole 1201 to connect with the environmental object, thereby fastening the fixing base 10, such as the fixing body 11, to the environmental object. It is understood that the connector may be a nail (e.g., a screw for screwing, a nail driven into the environmental object, a bolt, etc.), a strap, a wire, a metal ring, etc.

[0040] In some embodiments, there may be multiple first fixing parts 12, which can more stably mount the fixing seat 10, such as the fixing body 11, onto the environment. In some embodiments, there may be four first fixing parts 12, so that the fixing seat 10, such as the fixing body 11, is subjected to uniform force.

[0041] In some embodiments, the first fixing hole 1201 may include multiple hole segments, such as a third hole segment 1202 and a fourth hole segment 1203. The third hole segment 1202 may be disposed on a first surface 111. The fourth hole segment 1203 may be disposed on a second surface 112. The third hole segment 1202 and the fourth hole segment 1203 may communicate with each other. In some embodiments, because the diameter of the third hole segment 1202 is larger than the diameter of the fourth hole segment 1203, or because the third hole segment 1202 and the fourth hole segment 1203 are misaligned, or because the cross-sectional area of ​​the third hole segment 1202 is larger than the cross-sectional area of ​​the fourth hole segment 1203, the hole wall of the third hole segment 1202 and the hole wall of the fourth hole segment 1203 are fitted together to form a limiting portion, such as a third limiting portion. When the connector is inserted into the first fixing hole 1201, it can extend into the third hole section 1202. However, part of the structure of the connector is limited by the third limiting part at the connection between the third hole section 1202 and the fourth hole section 1203, and cannot enter the fourth hole section 1203. Therefore, it will not slip out of the first fixing hole 1201, which helps to improve the reliability of the connection between the connector and the environment.

[0042] In some embodiments, the fixing base 10, such as the fixing body 11, may be provided with a second fixing part 13. The second fixing part 13 can be installed on the environmental object by screwing, snapping, welding, plugging, binding, or other installation methods well known to those skilled in the art, which will not be elaborated further. Thus, the second fixing part 13 can realize the installation of the fixing base 10, such as the fixing body 11, on the environmental object. In some embodiments, the installation method of the second fixing part 13 may be different from the installation method of the first fixing part 12, that is, the way the second fixing part 13 is installed on the environmental object is different from the way the first fixing part 12 is installed on the environmental object.

[0043] Understandably, in order to install the mounting base 10, such as the mounting body 11, on an environmental object, it can be installed using the first fixing part 12 and / or the second fixing part 13. Of course, there are other methods as well, which will not be elaborated here. The cooperation of the first fixing part 12 and the second fixing part 13 can realize various installation methods for the mounting base 10, such as the mounting body 11, to better adapt to the environmental object and reduce the occurrence of installation problems caused by the environmental object.

[0044] In some embodiments, the second fixing part 13 may be provided with a second fixing hole 1301 located on the side surface 113, such as the first side surface 1131 or the second side surface 1132. A connector can then pass through the second fixing hole 1301 to connect with an environmental object, thereby fastening the fixing seat 10, such as the fixing body 11, to the environmental object. It is understood that the connector may be a nail (e.g., a screw for threading, a nail driven into the environmental object, a bolt, etc.), a strap, a wire, a metal ring, etc. In some embodiments, the second fixing hole 1301 on the first side surface 1131 may be the same as the second fixing hole 1301 on the second side surface 1132; that is, the second fixing hole 1301 may extend from the first side surface 1131 to the second side surface 1132.

[0045] In some embodiments, the first fixing hole 1201 can be used to pass through a rigid fixing member (e.g., a nail, a metal part, etc.), and the second fixing hole 1301 can be used to pass through a flexible fixing member (e.g., a strap, a wire, a metal ring).

[0046] In some embodiments, the length of the second fixing hole 1301 extending on the surface of the fixing seat 10, such as the fixing body 11, may be greater than the length of the first fixing hole 1201 extending on the surface of the fixing seat 10, such as the fixing body 11, thereby making the first fixing hole 1201 more adaptable to wider flexible fasteners, so that the fixing seat 10, such as the fixing body 11, is subjected to uniform force and improves the connection stability with environmental objects.

[0047] In some embodiments, the first fixing holes 1201 may be distributed on both sides of the second fixing holes 1301 along their length, so that the second fixing holes 1301 are located at the stress points. The wider connector ensures that the fixing seat 10, such as the fixing body 11, experiences uniform stress, thus improving the connection stability with the environment. Since the fixing method of rigid fasteners differs from that of flexible fasteners, the distribution of the first fixing holes 1201 is necessary to ensure uniform stress on the fixing seat 10, such as the fixing body 11, thereby improving the connection stability between the connector and the environment.

[0048] It is understood that in some embodiments, the second fixing hole 1301 may also be provided on the first surface 111. Specifically, the setting method of the second fixing hole 1301 on the side surface 113 can be referred to, and will not be described in detail.

[0049] In some embodiments, the second surface 112 may be provided with a first recessed area 1121. The first recessed area 1121 facilitates the insertion of some environmental objects, thereby enabling the positioning of the fixing base 10, such as the fixing body 11, and also improving connection stability. Furthermore, the provision of the first recessed area 1121 allows for space for environmental objects, facilitating the installation of the fixing base 10, such as the fixing body 11, on different environmental objects. Moreover, the provision of the first recessed area 1121 can reduce the overall weight of the fixing base 10, such as the fixing body 11, and reduce the load-bearing capacity requirements on the environmental objects.

[0050] In some embodiments, the settling depth and location of the first sinking zone 1121 can enable the first sinking zone 1121 to communicate with the second fixing hole 1301. Furthermore, in some embodiments, the connector can extend from the first sinking zone 1121 into the second fixing hole 1301 and then connect with the environment.

[0051] In some embodiments, the first recessed area 1121 may extend towards the side closer to the fourth side surface 1134 to form a limiting notch 1001 on the fourth side surface 1134. The limiting notch 1001 facilitates the insertion of a connector to position the mounting base 10, such as the mounting body 11. It also facilitates circuit routing, allowing the circuit wires to enter the mounting bracket 101 through the limiting notch 1001, and then into the camera module 102 and / or the solar panel 103 to achieve electrical connection. In some embodiments, the limiting notch 1001 may also allow space for environmental objects, facilitating the mounting of the mounting base 10, such as the mounting body 11, on different environmental objects.

[0052] In some embodiments, the fourth side surface 1134 may be referred to as the third side surface, and the first recessed area 1121 extends to the third side surface to form a limiting notch 1001 on the third side surface.

[0053] In some embodiments, the sidewall of the first recessed area 1121 may be configured as a limiting portion, such as a first limiting portion, to cooperate with the wall of the second fixing hole 1301. When the connector is inserted into the second fixing hole 1301, the structure may be partially limited by the first limiting portion at the connection between the first recessed area 1121 and the second fixing hole 1301, thus preventing it from entering the second fixing hole 1301 and preventing it from slipping out of the second fixing hole 1301, which is beneficial for the stable connection between the connector and the environment.

[0054] In some embodiments, to better adapt to environmental objects, the first sinking area 1121 may include a first sub-sinking area 1122 and a second sub-sinking area 1123. Compared to the first sub-sinking area 1122, the second sub-sinking area 1123 is closer to the fourth side surface 1134. The sinking depth of the first sub-sinking area 1122 may be greater than that of the second sub-sinking area 1123 to better adapt to different environmental objects and make way for them. Furthermore, the first sub-sinking area 1122 and the second sub-sinking area 1123 may also be set at locations that do not affect the overall structure and strength, based solely on weight requirements. This can reduce the overall weight of the fixing base 10, such as the fixing body 11, and reduce the load-bearing capacity requirements on the environmental objects.

[0055] In some embodiments, the first sub-sinking area 1122 may be connected to the second sub-sinking area 1123.

[0056] In some embodiments, the second fixing hole 1301 may communicate with the second sub-sinking area 1123 or with the first sub-sinking area 1122.

[0057] In some embodiments, the second fixing hole 1301 may include multiple hole segments, such as a first hole segment 1302 and a second hole segment 1303. The second hole segment 1303 may connect the first recessed area 1121 and the first hole segment 1302. In some embodiments, because the diameter of the second hole segment 1303 is larger than the diameter of the first hole segment 1302, or the second hole segment 1303 is misaligned with the first hole segment 1302, or the cross-sectional area of ​​the second hole segment 1303 is larger than the cross-sectional area of ​​the first hole segment 1302, the hole wall of the second hole segment 1303 and the hole wall of the first hole segment 1302 are fitted together to form a limiting portion, such as a second limiting portion. When the connector passes through the first recessed area 1121 into the first fixing hole 1201, it can extend into the second hole section 1303. However, part of the connector's structure is limited by the second limiting part at the connection between the second hole section 1303 and the first hole section 1302, and thus cannot enter the first hole section 1302. Consequently, it will not slip out of the second fixing hole 1301, which is beneficial for the stable connection between the connector and the environment.

[0058] In some embodiments, a first hole segment 1302 is disposed on a side surface 113, such as a first side surface 1131 or a second side surface 1132. In some embodiments, the width of the first hole segment 1302 is smaller than the width of the second hole segment 1303, so that the hole wall of the first hole segment 1302 and the hole wall of the second hole segment 1303 are fitted together to form a second limiting portion.

[0059] In some embodiments, the second surface 112 may be provided with a second recessed area 1124. The second recessed area 1124 facilitates the insertion of some environmental objects, thereby enabling the positioning of the fixing base 10, such as the fixing body 11, and also improving connection stability. Furthermore, the provision of the second recessed area 1124 allows for space for environmental objects, facilitating the installation of the fixing base 10, such as the fixing body 11, on different environmental objects. Moreover, the provision of the second recessed area 1124 can reduce the overall weight of the fixing base 10, such as the fixing body 11, and reduce the load-bearing capacity requirements on the environmental objects.

[0060] In some embodiments, the second recessed area 1124 may be distributed around the first recessed area 1121 to assist the first recessed area 1121 in adapting to environmental objects. Of course, the second recessed area 1124 may also be set at a position that does not affect the overall structure and strength, depending only on weight requirements, thereby reducing the overall weight of the fixing base 10, such as the fixing body 11, and reducing the load-bearing capacity requirements on environmental objects.

[0061] In some embodiments, the second recessed area 1124 may be disposed adjacent to the first fixing hole 1201 to assist the first fixing hole 1201 in positioning the fixing seat 10, such as fixing the body 11, and to improve connection stability. In some embodiments, there may be multiple second recessed areas 1124 and first fixing holes 1201, with at least one second recessed area 1124 disposed around each first fixing hole 1201.

[0062] Please see Figure 1 , Figure 2 and Figure 5 The mounting base 10, for example, the mounting body 11, may be provided with a mounting part 14 to install the mounting component 20 and the assembly component 30. Of course, the mounting part 14 may not install the mounting component 20 and the assembly component 30, but directly install the camera module 102 and the solar panel 103. Or the mounting part 14 may cooperate with the camera module 102 and the solar panel 103 by cooperating with the mounting component 20 and the assembly component 30.

[0063] In some embodiments, the mounting portion 14 may be disposed on the first surface 111.

[0064] In some embodiments, the mounting portion 14 may include a rotating connector 141 disposed on the fixing base 10, such as the fixing body 11. The rotating connector 141 may have a rotation axis, such as a second rotation axis. In some embodiments, the third side surface 1133 and the fourth side surface 1134 may be located on opposite sides of the fixing body 11 along the second rotation axis. In some embodiments, the second rotation axis may be parallel to or intersect with the vertical direction.

[0065] In some embodiments, the mounting base 10, for example, the rotatable connector 141, can be rotatably connected to the mounting assembly 20, thereby allowing the mounting assembly 20 to rotate about a second rotation axis. This further adjusts the camera angle of the camera module 102, enabling the monitoring device 100, which limits the rotation angle, to better adapt to environmental objects and minimize the impact of environmental factors on video recording. Of course, the mounting base 10, for example, the rotatable connector 141, can also be connected to the mounting assembly 20 using screwing, snap-fitting, welding, plugging, bonding, or other connection methods well known to those skilled in the art, which will not be elaborated further.

[0066] In some embodiments, the rotating connector 141 may protrude from the fixed base 10, such as the fixed body 11, and may have an installation space 1401. The second rotation axis may be located within the installation space 1401, allowing the mounting assembly 20 to extend into the installation space 1401 to achieve a rotational connection. That is, the second rotation axis passes through the installation space 1401.

[0067] It is understandable that when object a is mounted on surface c of object b, object a protrudes from surface c, which can be considered a protrusion setting.

[0068] In some embodiments, the rotating connector 141 may include a first sub-protrusion 143 and a second sub-protrusion 144 disposed opposite to each other. The first sub-protrusion 143 and / or the second sub-protrusion 144 may be rotatably connected to the mounting assembly 20. Furthermore, in some embodiments, the first sub-protrusion 143 or the second sub-protrusion 144 may be omitted.

[0069] In some embodiments, the first sub-protrusion 143 and the second sub-protrusion 144 may be spaced apart in the direction of the second rotation axis.

[0070] In some embodiments, the mounting space 1401 may be disposed between the first sub-protrusion 143 and the second sub-protrusion 144. That is, in some embodiments, the mounting space 1401 is formed by the first sub-protrusion 143 and the second sub-protrusion 144.

[0071] In some embodiments, the rotating connector 141 may have a rotating shaft 145 extending along a second rotation axis, the rotating shaft 145 being configured to rotate about the second rotation axis. The rotating shaft 145 may be connected to the mounting assembly 20, thereby realizing a rotating connection between the rotating connector 141 and the mounting assembly 20. In some embodiments, the rotating shaft 145 may also not rotate and be directly fixed to the rotating connector 141. In some embodiments, the rotating shaft 145 may be part of the mounting assembly 20. In some embodiments, the rotating shaft 145 may also be partially located on the rotating connector 141 and partially located on the mounting assembly 20. It is understood that in order to realize the rotating connection between the rotating connector 141 and the mounting assembly 20, the rotating shaft 145 may also be configured with other forms of structure, or even without the rotating shaft 145, other structures may be used to realize the rotating connection. Specific rotating connection settings can be made according to the technical solutions described in the art, and will not be elaborated further.

[0072] In some embodiments, the rotating shaft 145 is rotatably connected to the first sub-protrusion 143 and / or the second sub-protrusion 144.

[0073] In some embodiments, the rotating connector 141 can be used to directly mount the camera module 102.

[0074] In some embodiments, in order to fix the mounting component 20 after it has been rotated and adjusted, the fixing base 10 may further include an elastic fastener 16 disposed on the fixing body 11. The elastic fastener 16 is provided with a locking part 161, which is used to lock the mounting component 20 to fix the mounting component 20 and prevent the mounting component 20 from rotating.

[0075] The elastic fastener 16 may be made of an elastic material, or have a portion of its structure made of an elastic material, or be a component that uses an elastic material to provide power. The elastic fastener 16 can be elastically deformed due to the elastic material, for example, elastic deformation of the elastic material, elastic deformation of the part that uses the elastic material, or elastic deformation of the elastic material in the component.

[0076] Due to the elastic deformation of the elastic fastener 16, the locking part 161 can be located in a first position, a second position, or a position between the first and second positions. In the first position, the locking part 161 can be locked with the mounting component 20, thereby achieving a limiting engagement with the rotating connector 141. Under user operation, the elastic fastener 16 is subjected to force, causing the locking part 161 to move from the first position to the second position. When the user is not operating, the elastic fastener 16 is not subjected to force, and based on the elastic deformation of the elastic fastener 16, the locking part 161 moves from the second position to the first position.

[0077] In some embodiments, the elastic fastener 16 in the first position may be in a natural state (i.e., without elastic deformation, or in a stable state), or it may be in an elastically deformed state. In some embodiments, the degree of elastic deformation of the elastic fastener 16 in the first position may be less than the degree of elastic deformation of the elastic fastener 16 in the second position. The elastic deformation of the elastic fastener 16 is used to reset the elastic fastener 16 and reset it to a state where it is secured to the mounting component 20.

[0078] In some embodiments, the resilient fastener 16 may be disposed opposite to the second rotation axis, thereby limiting the mounting assembly 20 in a direction perpendicular to the second rotation axis.

[0079] In some embodiments, the distance between the locking part 161 and the second rotation axis in the first position may be less than the distance between the locking part 161 and the rotation axis in the second position. The elastic deformation of the elastic locking part 16 is used to reset the elastic locking part 16 and reset it to a state of being locked with the mounting component 20.

[0080] In some embodiments, the fixing base 10, such as the fixing body 11, may be provided with a mounting groove 1002 communicating with the mounting space 1401. A resilient fastener 16 may be disposed within the mounting groove 1002. In some embodiments, the mounting groove 1002 may be a through groove. In some embodiments, the resilient fastener 16 may obstruct the mounting groove 1002. In some embodiments, the resilient fastener 16 may be located within the mounting groove 1002 when it elastically deforms, and may move within the mounting groove 1002 when the degree of elastic deformation changes, thus allowing the mounting groove 1002 to accommodate the resilient fastener 16. Furthermore, in a further embodiment, the mounting groove 1002 may be omitted. In some embodiments, the resilient fastener 16 may be an integral structure with the fixing body 11.

[0081] In some embodiments, the mounting groove 1002 may be provided on the fixing seat 10, for example, on the part of the fixing body 11 located between the first sub-protrusion 143 and the second sub-protrusion 144.

[0082] In some embodiments, the mounting groove 1002 may be disposed on the first surface 111. In some embodiments, the mounting groove 1002 may be connected to a first recessed area 1121, such as a first sub-recessed area 1122. In some embodiments, the settling depth of the first recessed area 1121, such as the first sub-recessed area 1122, is adjustable, such that the first recessed area 1121, such as the first sub-recessed area 1122, is directly connected to the mounting space 1401, thereby making the first recessed area 1121, such as the first sub-recessed area 1122, a mounting groove.

[0083] In some embodiments, the mounting groove 1002 may extend to the fourth side surface 1134, thereby forming a limiting notch 1001 on the fourth side surface 1134.

[0084] In some embodiments, the mounting groove 1002 is configured to extend to the side of the second sub-protrusion 144 opposite to the first sub-protrusion 143, that is, to extend towards the side near the fourth side surface 1134, so that the portion of the elastic fastener 16 (e.g., the touch portion, the free end) can be located on the side of the second sub-protrusion 144 opposite to the first sub-protrusion 143, extending out of the mounting space 1401 for easy user operation. For example, when the elastic fastener 16 is secured to the mounting assembly 20, the user can squeeze the portion of the elastic fastener 16 located on the side of the second sub-protrusion 144 opposite to the first sub-protrusion 143, so that the locking portion 161 is in a second position, or a position between the first position and the second position, so that the elastic fastener 16 and the mounting assembly 20 are not secured, and then the mounting assembly 20 can be rotated for angle adjustment.

[0085] In some embodiments, the mounting groove 1002 is provided such that the fixing seat 10, for example the fixing body 11, connects the second sub-protrusion 144 to both sides of the mounting groove 1002.

[0086] Understandably, when the locking part 161 is in the first position, the elastic fastener 16 is in the first state. When the locking part 161 is in the second position, the elastic fastener 16 is in the second state. When the locking part 161 is in a position between the first and second positions, the elastic fastener 16 is in a state between the first and second states.

[0087] In some embodiments, the mounting part 14 may include a mounting body 142. The mounting body 142 may be disposed on the fixed body 11 and connected and fixed to the assembly assembly 30. The connection may be made by screwing, snap-fitting, welding, plugging, bonding or other connection methods known to those skilled in the art, which will not be described in detail.

[0088] In some embodiments, the mounting body 142 may have a connecting groove 1402 provided on the fixing base 10, such as the fixing body 11. The connecting groove 1402 allows the assembly component 30 to be partially placed within the connecting groove 1402 for connection. In some embodiments, the connecting groove 1402 may be a through groove. In some embodiments, a pin may be inserted into the connecting groove 1402 to connect the mounting body 142 and the assembly component 30.

[0089] In some embodiments, the mounting body 142 may have a third sub-protrusion 1421 disposed on the fixing base 10, such as the fixing body 11. The third sub-protrusion 1421 can be used to position the assembly component 30, and can also assist the connecting groove 1402 in limiting the installation of the assembly component 30.

[0090] In some embodiments, there may be two third sub-protrusions 1421, spaced apart, to form a limiting space 1403 between the two third sub-protrusions 1421, further positioning and limiting the assembly assembly 30, and improving the connection stability with the assembly assembly 30. In some embodiments, the limiting space 1403 may be a groove, and thus, a groove may be provided on the surface of the third sub-protrusion 1421 to form the limiting space 1403. In a further embodiment, the groove may be a through groove. In a further embodiment, the groove may divide one third sub-protrusion 1421 into two. It is understood that there may be multiple third sub-protrusions 1421, or it may not be limited to two.

[0091] In some embodiments, the mounting body 142 can directly mount the solar panel 103.

[0092] In some embodiments, the third sub-protrusion 1421 and the connecting groove 1402 may be disposed on the third side surface 1133. In some embodiments, the third side surface 1133 may be referred to as the first side surface, and the mounting body 142, such as the third sub-protrusion 1421 and the connecting groove 1402, may be disposed on the first side surface.

[0093] In some embodiments, the third side surface 1133 may extend onto the rotating connector 141, for example, the first sub-protrusion 143. Furthermore, the mounting body 142 may be at least partially disposed on the rotating connector 141. In some embodiments, the included angle A between the first surface 111 and the third side surface 1133 may be greater than or equal to 15° and less than or equal to 80° to adjust the position of the solar panel 103.

[0094] Please see Figure 1 The mounting component 20 may be in the form of a frame structure, or may be configured as a structural type known to those skilled in the art, which will not be elaborated further.

[0095] In some embodiments, the mounting assembly 20 may include a fixed body 21 rotatably connected to the mounting base 10, such as the fixed body 11, a first connecting rod 22 pluggably connected to the fixed body 21, and a second connecting rod 23 connected to the first connecting rod 22. The first connecting rod 22 allows the fixed body 21 to be connected to the second connecting rod 23 via the first connecting rod 22. In some embodiments, the mounting assembly 20, for example, the second connecting rod 23, may be connected to the camera module 102. Of course, the fixed body 21 may also be installed with the first connecting rod 22 using other detachable installation methods, or even directly fixedly connected, which will not be elaborated further.

[0096] Understandably, in some embodiments, the fixing body 21 may also be referred to as a connecting rod. Furthermore, in a further embodiment, the number of connecting rods in the mounting assembly 20 may be multiple, and may not be limited to the fixing body 21, the first connecting rod 22, and the connecting rod 22.

[0097] In some embodiments, the fixing body 21 can rotate about a second rotation axis, thereby allowing the mounting components 20, such as the first link 22 and the second link 23, to also rotate about the second rotation axis. In some embodiments, the second link 23 can be configured to adjust the camera angle of the camera module 102. Furthermore, the first link 22 and the second link 23 can also be rotatably connected, for example, through a shaft, universal joint, or other structures well known to those skilled in the art. In some embodiments, the second link 23 can rotate relative to the first link 22 about an axis perpendicular to the second rotation axis.

[0098] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 , Figure 6 for Figure 1 The illustrated embodiment shows a partial structural diagram of the mounting component 20 in some embodiments. Figure 7 for Figure 6 A schematic diagram of the structure of the fixing body 21 in the embodiment shown. Figure 8 for Figure 6 The schematic diagram of the first connecting rod 22 in the embodiment shown is as follows. Figure 9 for Figure 1 The cross-sectional view of the fixing base 10 and the fixing body 21 in the embodiment shown is shown. Figure 10 for Figure 9 The illustrated embodiment shows a cross-sectional view of the mounting base 10 and the mounting body 21 in some other embodiments. The mounting assembly 20, such as the mounting body 21, is rotatably connected to the mounting base 10, such as the rotatable connector 141, to rotate about a second rotation axis. In some embodiments, the mounting assembly 20, such as the mounting body 21, may extend into the mounting space 1401 and be rotatably connected to the mounting base 10, such as the rotatable connector 141. In some embodiments, the mounting assembly 20, such as the mounting body 21, may be disposed between the first sub-protrusion 143 and the second sub-protrusion 144, and be rotatably connected to the first sub-protrusion 143 and / or the second sub-protrusion 144. In some embodiments, the mounting body 21 may be part of the mounting base 10, thereby allowing the mounting assembly 20 to be connected to the mounting base 10 via a plug-in connection, although other methods of connection are also possible.

[0099] In some embodiments, the mounting component 20, such as the fixing body 21, may have at least one sub-fixing part 211, which can be engaged with the elastic fastener 16, such as the locking part 161, to limit the mounting component 20 and / or the camera module 102. In some embodiments, the locking method between the sub-fixing part 211 and the locking part 161 may be a limiting method in which a locking block is placed in a hole, or a limiting method in which a protrusion is located in a slot, or of course, other methods that can be connected, fixed, and detached, which will not be elaborated further.

[0100] In some embodiments, the elastic fastener 16 in the first state can be locked and limited with the mounting component 20, such as the fixing body 21, so that the locking part 161 is in the first position and locked and limited with the sub-fixing part 211.

[0101] In some embodiments, at least one sub-fixing part 211 may be arranged in the rotation direction of the mounting assembly 20, such as the fixing body 21, and each sub-fixing part 211 may correspond to a rotation angle of the mounting assembly 20 and / or the camera module 102 about the second rotation axis, thereby enabling multi-level angle adjustment.

[0102] In some embodiments, two adjacent sub-fixing portions 211 may limit the rotation angle of the mounting assembly 20 and / or the camera module 102 to 10-75°. That is, when the mounting assembly 20 and / or the camera module 102 rotates, if the elastic fastener 16, such as the locking portion 161, engages with one of the two adjacent sub-fixing portions 211 and then engages with the other, the mounting assembly 20 and / or the camera module 102 may rotate 10-75°.

[0103] In some embodiments, the mounting component 20, such as the fixing body 21, may have an end face 213. The end face 213 may be formed on the side of the mounting component 20, such as the fixing body 21, opposite to the resilient fastener 16. In some embodiments, the resilient fastener 16 in a first state may be disposed opposite to the end face 213 and opposite to a second rotation axis. In some embodiments, at least one sub-fixing portion 211 is disposed on the end face 213.

[0104] In some embodiments, the fixing body 21 may have a sub-plug portion 212 for plugging into the first connecting rod 22 to achieve a detachable connection. In some embodiments, the sub-plug portion 212 may have a tongue 214 for plugging into the first connecting rod 22. In some embodiments, the sub-plug portion 212 may have a socket 2101 provided on the fixing body 21 for plugging into the first connecting rod 22. In some embodiments, the tongue 214 may cooperate with the socket 2101 to achieve a plugging connection between the fixing body 21 and the first connecting rod 22.

[0105] In some embodiments, the first link 22 may have a insertion space 2102 to accommodate a tongue 214, such that the tongue 214 is placed in the insertion space 2102 and inserted into the first link 22.

[0106] In some embodiments, the first link 22 may have an elastic tab 221, which may pass through the insertion hole 2101 and be snapped into the fixing body 21, for example, the sub-insertion portion 212. In some scenarios, when the fixing body 21 and the first link 22 are inserted and connected, the user can move the elastic tab 221 to cause the elastic tab 221 to elastically deform, thereby releasing the snap-fit ​​connection with the fixing body 21. The elastic tab 221 can then be pulled out of the insertion hole 2101, and the tongue 214 can be pulled out of the insertion space 2102, thus achieving disassembly.

[0107] In some embodiments, the camera module 102 may be connected to the fixed body 21 by means of the first connecting rod 22 and the fixed body 21.

[0108] In some embodiments, the camera module 102 may be connected to the fixed base 10 by means of a connection between the fixed body 21 and the fixed base 10. For details, please refer to the connection method between the fixed body 21 and the fixed base 10, which will not be described in detail.

[0109] Please see Figure 1 , Figure 11 and Figure 12 , Figure 11 for Figure 1 The diagram shown illustrates the structural arrangement of the assembly component 30 and the fixing base 10 in some embodiments. Figure 12 for Figure 11 A cross-sectional view of the assembly component 30 mating with the fixing base 10 in the illustrated embodiment. Please refer to [link / reference]. Figure 1 The assembly component 30 may be in the form of a frame structure, or may be configured as a structural type known to those skilled in the art, which will not be elaborated here.

[0110] In some embodiments, the assembly 30 may include an assembly body 31 connected to the mounting base 10, such as the mounting body 11. In some embodiments, the assembly 30, such as the assembly body 31, may be connected to the solar panel 103.

[0111] In some embodiments, the assembly component 30, such as assembly body 31, may be connected to the fixed base 10, such as mounting body 142. In some embodiments, the assembly component 30, such as assembly body 31, may have a positioning space 3001. When the assembly component 30, such as assembly body 31, is connected to the fixed base 10, such as mounting body 142, a third sub-protrusion 1421 may extend into the positioning space 3001 for positioning. In some embodiments, the inner wall of the assembly component 30, such as assembly body 31, within the positioning space 3001 may be in close contact with the surface of the third sub-protrusion 1421 to achieve positioning. In some embodiments, the assembly component 30, such as assembly body 31, may have a positioning part 311 provided in the positioning space 3001. When the assembly component 30, such as assembly body 31, is connected to the fixed base 10, such as mounting body 142, the positioning part 311 may be placed within the limiting space 1403 for positioning.

[0112] In some embodiments, the assembly component 30, such as the assembly body 31, may have a fixing groove 312 to cooperate with the connecting groove 1402 to achieve connection and fixation. For example, a nail body passes through the fixing groove 312 and is placed in the connecting groove 1402 to achieve connection and fixation with the fixing seat 10, such as the mounting body 142.

[0113] In some embodiments, the solar panel 103 can be directly fixed to the mounting base 10, such as the mounting body 11. In some embodiments, the solar panel 103 can be directly fixed to the mounting base 10, such as the mounting body 142. In a further embodiment, the solar panel 103 can be fixed to the mounting base 10, such as the mounting body 142, using an assembly component 30, such as an assembly 31, and the mounting base 10, such as the mounting body 142, which will not be described in detail.

[0114] Please see Figure 1 and Figure 13 , Figure 13 for Figure 1 The illustrated embodiment shows a schematic diagram of the camera module 102. The camera module 102 may include a camera housing 40, a first camera 50 mounted on the camera housing 40, and a second camera 60 mounted on the camera housing 40. The camera housing 40 may be connected to the mounting assembly 20 via screwing, snap-fitting, welding, plugging, bonding, or other connection methods well known to those skilled in the art, which will not be elaborated upon. Alternatively, the camera housing 40 may be directly mounted on the mounting base 10.

[0115] In some embodiments, the camera housing 40 may include a first housing 41 and a second housing 42 connected together. In some embodiments, the first housing 41 and the second housing 42 may be connected by screwing, snap-fitting, welding, plugging, bonding, or other connection methods well known to those skilled in the art, which will not be elaborated further. In some embodiments, the first housing 41 and the second housing 42 are snap-fitted together.

[0116] In some embodiments, the first housing 41 may include a first sub-housing 411 and a second sub-housing 412 arranged side-by-side and connected. The second housing 42 may be located on the same side of the first sub-housing 411 and the second sub-housing 412, and may be connected to the first sub-housing 411 and the second housing 412. In some embodiments, the first sub-housing 411 and the second housing 42 may be snap-fitted together. In some embodiments, the second sub-housing 412 and the second housing 42 may be snap-fitted together.

[0117] In some embodiments, the second sub-housing 412 may have a first mounting surface 4121 on the side near the first sub-housing 411. In some embodiments, the second sub-housing 412 may have a second mounting surface 4122 on the side opposite to the second housing 42. In some embodiments, the first mounting surface 4121 and the second mounting surface 4122 may be connected.

[0118] In some embodiments, the second mounting surface 4122 and the first camera 50 and the second camera 60 may be located on the same side of the connecting housing 44 on the first rotation axis.

[0119] In some embodiments, the first sub-housing 411 may protrude from the second sub-housing 412, for example, the first mounting surface 4121.

[0120] In some embodiments, the first sub-housing 411 and the second sub-housing 412 cooperate to form an assembly space 4101 on the side of the first sub-housing 411 opposite to the first housing 41, for mounting the first camera 50 and the second camera 60. That is, the assembly space 4101 is located on the side of the second sub-housing 412 close to the first sub-housing 411. Furthermore, the connecting housing 44 is located on the same side of the first camera 50 and the second camera 60, and the first camera 50 and the second camera 60 are located on the same side of the main housing 43.

[0121] In some embodiments, the camera housing 40 may include a main housing 43 and a connecting housing 44. The main housing 43 may be formed by connecting a second sub-housing 412 and a second housing 42. The connecting housing 44 may be formed by connecting a first sub-housing 411 and a second housing 42. Furthermore, the connecting housing 44 may protrude from a first mounting surface 4121. The first mounting surface 4121 and the second mounting surface 4122 may be disposed on the main housing 43. That is, the first mounting surface 4121 is disposed on the side of the main housing 43 closest to the first camera 50 and the second camera 60.

[0122] In some embodiments, the second housing 42 is configured such that the surface of the connecting housing 44 on the side opposite to the first camera 50 and the second camera 60 is flush with the surface of the main housing 43.

[0123] In some embodiments, the main housing 43 may be used to house a circuitry for processing and / or storing video recorded by the first camera 50 and the second camera 60. Even in some embodiments, the circuitry may power the camera module 102.

[0124] In some embodiments, the camera housing 40, such as the connecting housing 44, may have a mounting hole, such as a first mounting hole 4111, so that the first camera 50 can be inserted into the first mounting hole 4111, thereby achieving a rotatable connection between the first camera 50 and the camera housing 40, such as the connecting housing 44, and allowing it to rotate about a rotation axis, such as a first rotation axis. In some embodiments, the first mounting hole 4111 may be provided on the connecting housing 44, such as a first sub-housing 411. In some embodiments, the first camera 50 may be partially placed inside the camera housing 40, such as the connecting housing 44. In some embodiments, the first rotation axis may extend through the connecting housing 44, such as the first sub-housing 411. In some embodiments, the first camera 50 may be rotatably connected to the connecting housing 44, such as the first sub-housing 411.

[0125] In some embodiments, to prevent raindrops, dust, etc., from entering the camera housing 40, such as the connecting housing 44, a protrusion 4113 may be provided on the edge of the first mounting hole 4111 for shielding. In some embodiments, the protrusion 4113 may be provided in a position lower than the first mounting hole 4111 (the lowest point in the vertical direction) in the camera housing 40, such as the connecting housing 44, so that when raindrops flow on the camera housing 40, such as the connecting housing 44, they can flow onto the protrusion 4113 and are less likely to accumulate at the first mounting hole 4111.

[0126] In some embodiments, the protrusion 4113 may include a first sub-protrusion 4114 disposed on the side of the edge of the first mounting hole 4111 facing away from the main housing 43 and a second sub-protrusion 4115 disposed on the side of the edge of the first mounting hole 4111 facing away from the reinforcing housing 45, wherein the first sub-protrusion 4114 and the second sub-protrusion 4115 are connected. Since the positions where the first sub-protrusion 4114 and the second sub-protrusion 4115 are disposed are unobstructed, it is very easy for raindrops, dust and other objects to enter the camera housing 40, such as the connecting housing 44, and thus the first sub-protrusion 4114 and the second sub-protrusion 4115 provide protection.

[0127] In some embodiments, the camera housing 40, such as the connecting housing 44, may have a mounting hole, such as a second mounting hole 4112, so that the second camera 60 can be inserted into the second mounting hole 4112, thereby realizing a rotatable connection between the second camera 60 and the camera housing 40, such as the connecting housing 44, and allowing it to rotate about a rotation axis, such as a first rotation axis. It is understood that the cooperation method between the second camera 60 and the camera housing 40, such as the connecting housing 44, can be referred to the cooperation method between the first camera 50 and the camera housing 40, such as the connecting housing 44, and will not be described in detail. Additionally, a protrusion 4113 may be provided at the second mounting hole 4112. This will not be described in detail. In some embodiments, the second camera 60 can be rotatably connected to the connecting housing 44, such as the first sub-housing 411.

[0128] In some embodiments, the connecting housing 44, such as the first sub-housing 411, can be used to mount the first camera 50 and the second camera 60. In a further embodiment, to achieve a thinner connecting housing 44, the thickness of the connecting housing 44 is controlled, which may result in the connecting housing 44 failing to guarantee the stability of the first camera 50 and the second camera 60. Furthermore, the camera housing 40 may also include a reinforcing housing 45. The reinforcing housing 45 may protrude from the first mounting surface 4121 and may be connected to the connecting housing 44, such as the first sub-housing 411, thereby connecting and supporting the connecting housing 44, such as the first sub-housing 411, improving the stability of the first camera 50 and the second camera 60, while also achieving a thinner connecting housing 44.

[0129] In some embodiments, the reinforced housing 45 may be located between the first camera 50 and the second camera 60, thereby better connecting and supporting the connecting housing 44, such as the first sub-housing 411, ensuring the overall force balance of the connecting housing 44, such as the first sub-housing 411, and also enhancing the appearance of the camera housing 40.

[0130] In some embodiments, the reinforced housing 45 is located on the side of the plane defined by the two first rotation axes (i.e., the first rotation axes corresponding to the first camera 50 and the second camera 60, respectively) that is away from the main housing 43, so as to enhance the appearance of the camera housing 40.

[0131] Please see Figure 13 and Figure 14 , Figure 14 for Figure 13 The illustrated embodiment shows a cross-sectional schematic diagram of the camera housing 40 in some embodiments. The reinforced housing 45 may include a body 451 and a decorative element 452. The decorative element 452 is disposed on the body 451 to enhance the appearance of the camera housing 40, and may also be used for information transmission.

[0132] In some embodiments, the body 451 may be connected to a main housing 43, such as a second sub-housing 412. In some embodiments, the body 451 may be connected to a connecting housing 44, such as a first sub-housing 411. In some embodiments, a mounting opening 4102 may be provided on the side of the body 451 opposite to the main housing 43, such as the second sub-housing 412, for mounting a decorative element 452. In some embodiments, the mounting opening 4102 may also extend toward the side of the connecting housing 44, such as the first sub-housing 411, and may extend onto the side of the body 451 opposite to the connecting housing 44, such as the first sub-housing 411.

[0133] In some embodiments, the decorative element 452 may be disposed at the mounting port 4102. For example, the decorative element 452 may be disposed at the mounting port 4102 on the side of the body 451 opposite to the main housing 43, such as the second sub-housing 412. For example, the decorative element 452 may be disposed at the mounting port 4102 on the side of the body 451 opposite to the connecting housing 44, such as the first sub-housing 411.

[0134] In some embodiments, the decorative element 452 may be connected to the body 451 by screwing, snap-fitting, welding, plugging, bonding or other connection methods known to those skilled in the art, which will not be elaborated further.

[0135] Please see Figure 14 and Figure 15 , Figure 15 for Figure 14 The illustrated embodiment shows a schematic diagram of the structure of the decorative element 452 in some embodiments. The decorative element 452 may include a first sub-decorative element 4524 and a second sub-decorative element 4525. The first sub-decorative element 4524 may be located on the side of the body 451 opposite to the main housing 43, such as the second sub-housing 412. The second sub-decorative element 4525 may be located on the side of the body 451 opposite to the connecting housing 44, such as the first sub-housing 411. In some embodiments, the first sub-decorative element 4524 and the second sub-decorative element 4525 may be an integral structure. In some embodiments, the first sub-decorative element 4524 may be bonded and fixed to the body 451. In some embodiments, the second sub-decorative element 4525 may be detachably connected to the body 451. In some embodiments, the second sub-decorative element 4525 may be snap-fit ​​connected to the body 451. In some embodiments, the first sub-decorative element 4524 achieves its connection with the body 451 by relying on the connection between the second sub-decorative element 4525 and the body 451.

[0136] In some embodiments, decorative element 452, such as the first sub-decorative element 4524, may include a decorative body 4521, a light guide 4522, and a light source 4523. It is understood that the second sub-decorative element 4525 may also be configured according to the first sub-decorative element 4524. In a further embodiment, the decorative body of the second sub-decorative element 4525 and the decorative body 4521 of the first sub-decorative element 4524 are integrally formed. In a further embodiment, the light guide of the second sub-decorative element 4525 and the light guide 4522 of the first sub-decorative element 4524 are integrally formed. In a further embodiment, the light source of the second sub-decorative element 4525 and the light source 4523 of the first sub-decorative element 4524 are the same.

[0137] In some embodiments, the decorative body 4521 is disposed at the mounting opening 4102 to serve as the main structure of the decorative element 452. In some embodiments, the decorative body 4521 may be provided with a through hole 4103 to cooperate with the light guide 4522 and / or the light source 4523.

[0138] In some embodiments, the light guide 4522 may be disposed on the side of the decorative body 4521 near the main housing 43 and at least partially placed within at least a portion of the through holes 4103, thereby enabling light transmission. Of course, when light transmission is not required, the light guide 4522 may be replaced with other materials, allowing the material to fill the through holes 4103. Even materials that enhance aesthetic appeal may be used to fill the through holes 4103.

[0139] In some embodiments, the light source 4523 may be disposed on the side of the decorative body 4521 near the main housing 43. The light source 4523 can be used for information transmission or to enhance the aesthetic appeal. In some embodiments, the light source 4523 can transmit light through the light guide 4522 or through a through hole 4103 not filled by the light guide 4522.

[0140] In some embodiments, a sound outlet 4104 is provided on the second mounting surface 4122. Furthermore, the camera module 102 may also include a speaker 83 disposed within the camera housing 40, such as the main housing 43, and the speaker 83 may transmit sound through the sound outlet 4104. In some embodiments, the sound outlet 4104 is disposed adjacent to the reinforced housing 45.

[0141] Understandably, gaps are formed between the first camera 50 and the second camera 60 and the first mounting surface 4121. During ventilation, air will pass through these gaps, causing the first camera 50 and / or the second camera 60 to wobble against the camera housing 40 due to these gaps. This necessitates very strict control over these gaps. The reinforced housing 45 can cut off these gaps, thus minimizing the wobble of the first camera 50 and / or the second camera 60 caused by the gaps and reducing the requirements for gap control.

[0142] Please see Figure 16 , Figure 16 for Figure 13 The illustrated embodiment shows a partial structural diagram of the camera module 102 in some embodiments. The camera module 102 may further include a driving member 70 and a clearance control member 80. The driving member 70 and the clearance control member 80 may be installed inside the camera housing 40. The driving member 70 may be used to drive the first camera 50 to rotate. The clearance control member 80 may be used to abut against the side peripheral surface of the first camera 50 to control the clearance of the first camera 50 at a mounting hole, such as the first mounting hole 4111. It is understood that a driving member and a clearance control member may also be provided for the second camera 60, thereby driving the second camera 60 to rotate through the driving member, and controlling the clearance of the second camera 60 at a mounting hole, such as the second mounting hole 4112, through the clearance control member abutting against the side peripheral surface of the second camera 60. For the specific cooperation between the second camera 60 and the driving member, the clearance control member, and the camera housing 40, please refer to the cooperation between the first camera 50 and the driving member 70, the clearance control member 80, and the camera housing 40, which will not be described in detail here. Furthermore, the configuration of the second camera 60 can be referenced from that of the first camera 50, and will not be elaborated further. Additionally, the driving component 70 that drives the first camera 50 to rotate and the driving component that drives the second camera 60 to rotate can be the same. Furthermore, the clearance control component 80 can also be a single component, simultaneously abutting against the side peripheral surface of both the first camera 50 and the second camera 60, to control the clearance of the first camera 50 at a mounting hole, such as the first mounting hole 4111, and the clearance of the second camera 60 at a mounting hole, such as the second mounting hole 4112.

[0143] Please see Figure 16 The driving component 70 may include a driving assembly 71 and a transmission assembly 72. The driving assembly 71, the transmission assembly 72, and the first camera 50 are sequentially connected by a transmission mechanism, so that the driving assembly 71 can drive the first camera 50 to rotate through the transmission assembly 72.

[0144] Please see Figure 16 and Figure 17 , Figure 17 for Figure 16 The exploded view shows the driving component 71 in the illustrated embodiment. The driving component 71 can be installed within the main housing 43 to reduce the footprint on the connecting housing 44, thereby making the connecting housing 44 thinner and lighter. Of course, in other embodiments, the driving component 71 can also be disposed on other housings of the camera housing 40, such as the connecting housing 44 or the reinforcing housing 45, which will not be elaborated further. Furthermore, when the driving component 71 is driveably connected to the first camera 50 within the main housing 43, the transmission component 72 can be omitted.

[0145] In some embodiments, the drive assembly 71 may be disposed between the second sub-housing 412 and the second housing 42. In some embodiments, the drive assembly 71 may be mounted on the second sub-housing 412.

[0146] In some embodiments, the drive assembly 71 may include a motor 711, a transmission gear 712, and an isolation cover 713. The transmission gear 712 may be mounted on the motor 711 and driven to rotate by the motor 711. The transmission gear 712 may mesh with the transmission assembly 72 for transmission. The isolation cover 713 isolates the rotating parts of the motor 711 and the transmission gear 712, preventing interference between the circuit system and the rotating parts of the motor 711 and the transmission gear 712, and ensuring that the circuit system is not damaged by the rotating parts of the motor 711 and the transmission gear 712. In some embodiments, the isolation cover 713 is configured such that the transmission gear 712 is located inside the isolation cover 713.

[0147] In some embodiments, the isolation cover 713 may be disposed on the side of the drive assembly 71 facing away from the first camera 50 to isolate it from the circuit system as much as possible. In some embodiments, the motor 711 may be disposed on the isolation cover 713 so that the drive assembly 71 becomes a module, facilitating overall installation and disassembly. In some embodiments, the motor 711 and / or the isolation cover 713 may be connected to the camera housing 40, such as the main housing 43.

[0148] Please see Figure 17 and Figure 18 , Figure 18 for Figure 16 The schematic diagram of the isolation cover 713 in the illustrated embodiment shows that one side of the transmission gear 712 can be mounted on the rotating shaft of the motor 711, and the isolation cover 713 can be provided with a rotating shaft 7131 rotatably connected to the transmission gear 712 on the other side of the transmission gear 712. The rotating shaft of the motor 711 and the rotating shaft 7131 of the isolation cover 713 are coaxially arranged so that the transmission gear 712 is placed between the two rotating shafts to achieve stable rotation.

[0149] Please see Figure 16 and Figure 19 , Figure 19 for Figure 16 The illustrated embodiment shows a partial structural diagram of the camera module 102 in other embodiments. The transmission component 72 can be installed within the connecting housing 44 and is connected to the drive component 71, such as the transmission gear 712, so that the drive component 71 can drive the first camera 50 to rotate via the transmission component 72.

[0150] In some embodiments, the transmission assembly 72 may be installed between the first sub-housing 411 and the second housing 42. In some embodiments, the transmission assembly 72 may be installed on the first sub-housing 411.

[0151] In some embodiments, the transmission assembly 72 may include a gear 721. The gear 721 may be disposed between the second sub-housing 412 and the second housing 42. In some embodiments, the gear 721 may be disposed on the first sub-housing 411.

[0152] In some embodiments, gear 721 may include a core 7211 and teeth 7212, the teeth 7212 being distributed on the side circumferential surface of the core 7211. The teeth 7212 may mesh with a drive assembly 71, such as a transmission gear 712, to drive the first camera 50 to rotate. In some embodiments, gear 721 rotates about a first rotation axis.

[0153] In some embodiments, since the first camera 50 does not rotate at a large angle, not all the teeth 7212 on the gear 721 will be used. The excess teeth 7212 will increase the weight of the gear 721, and the load-bearing capacity requirement of the connecting housing 44 will also increase accordingly. Therefore, the side peripheral surface of the core 7211 can be divided into a toothed area 7201 and a toothless area 7202, with the teeth 7212 arranged in the toothed area 7201.

[0154] In some embodiments, the toothed area 7201 is configured to match the rotation angle of the first camera 50. Furthermore, the toothed area 7201 can allow the first camera 50 to rotate at an angle less than or equal to 180°, or less than or equal to 150°, or less than or equal to 120°, or less than or equal to 90°.

[0155] In some embodiments, the toothed region 7201 may allow the gear 721 to rotate at an angle less than or equal to 180°, or less than or equal to 150°, or less than or equal to 120°, or less than or equal to 90°.

[0156] In some embodiments, the toothed region 7201 may cause the rotation angle of the drive assembly 71 driving the gear 721 to be less than or equal to 180°, or less than or equal to 150°, or less than or equal to 120°, or less than or equal to 90°.

[0157] In some embodiments, the camera housing 40, for example, the connecting housing 44, may have an abutment portion 413. In some embodiments, the abutment portion 413 may be disposed on the first sub-housing 411. In some embodiments, the abutment portion 413 allows the first camera 50 to rotate to a position abutting against the abutment portion 413, thereby constraining the rotation angle of the first camera 50 and improving the problem of external wiring entanglement.

[0158] In some embodiments, the abutment portion 413 allows the gear 721 to rotate to a position abutting against the abutment portion 413, thereby constraining the rotation angle of the first camera 50 and improving the problem of external wiring tangling.

[0159] In some embodiments, the abutment portion 413 may be disposed adjacent to the toothless area 7202 and used to abut and limit the gear tooth 7212 to prevent the gear 721 from rotating, thereby limiting the rotation of the first camera 50.

[0160] In some embodiments, the abutment portion 413 may be adapted to the rotation angle of the first camera 50. Therefore, the abutment portion 413 may allow the first camera 50 to rotate at an angle less than or equal to 180°, or less than or equal to 150°, or less than or equal to 120°, or less than or equal to 90°.

[0161] In some embodiments, the abutment portion 413 may be adapted to the rotation angle of the first camera 50. Furthermore, the abutment portion 413 may cause the gear 721 to rotate at an angle less than or equal to 180°, or less than or equal to 150°, or less than or equal to 120°, or less than or equal to 90°.

[0162] Please see Figure 16 , Figure 19 , Figure 20 and Figure 21 , Figure 20 for Figure 16 A schematic diagram of the structure of the first camera 50 and the transmission component 72. Figure 21 for Figure 16 The illustrated embodiment shows a partial structural diagram of the camera module 102. The first camera 50 may be partially housed within the camera housing 40, for example, the connecting housing 44, for rotatable connection to the camera housing 40, for example, the connecting housing 44. In some embodiments, the first camera 50 may be driveably connected to the transmission assembly 72, so that the transmission assembly 72 drives the first camera 50 to rotate.

[0163] In some embodiments, the first camera 50 may be connected and engaged with the gear 721. In some embodiments, the first camera 50 may be connected and engaged with the core 7211. In some embodiments, the core 7211 is provided with a wiring hole 7203, and the external wiring of the first camera 50 may pass through the wiring hole 7203, thereby being electrically connected to the circuit system.

[0164] In some embodiments, the first camera 50 may include a camera body 51. The camera body 51 may be inserted into the first mounting hole 4111 and connected and engaged with a gear 721, such as a core 7211, to be rotatably connected to the camera housing 40.

[0165] In some embodiments, the first camera 50 may further include a bearing 52. The bearing 52 may be disposed at the first mounting hole 4111. The outer ring of the bearing 52 may be fixed to the camera housing 40, for example, the connecting housing 44, so that the first camera 50, for example, the camera body 51, is rotatably connected to the camera housing 40.

[0166] In some embodiments, the first camera 50, such as the camera body 51, may be fixed on the inner ring of the bearing 52, so that the first camera 50, such as the camera body 51, is rotatably connected to the camera housing 40. In some embodiments, the inner ring of the bearing 52 rotates about a first rotation axis.

[0167] In some embodiments, the gear 721 may be fixed on the inner ring of the bearing 52 so that the first camera 50, such as the camera body 51, is rotatably connected to the camera housing 40.

[0168] In some embodiments, the camera housing 40, for example, the connecting housing 44, may be provided with a screw connector 4116, which is used to press and fix the outer ring of the bearing 52 onto the connecting housing 44. The screw connector 4116 reduces the design complexity of the camera housing 40, for example, the connecting housing 44. In some embodiments, the screw connector 4116 may be screwed (i.e., threaded) to the first sub-housing 411 to press and fix the outer ring of the bearing 52 onto the first sub-housing 411. That is, the screw connector 4116 is provided on the first sub-housing 411.

[0169] In some embodiments, the camera housing 40, for example, the connecting housing 44, is surrounded by a retaining plate 4117 around the first mounting hole 4111. The retaining plate 4117 surrounds the bearing 52, thereby limiting the bearing 52 and reducing the clearance of the first camera 50 at the first mounting hole 4111. In some embodiments, the presence of the retaining plate 4117 is particularly important for securing the bearing 52. The screw connector 4116 facilitates the installation of the bearing 52 within the retaining plate 4117 and also facilitates the removal of the bearing 52. In some embodiments, the retaining plate 4117 also enhances the strength of the connecting housing 44, for example, the first sub-housing 411, and improves the load-bearing capacity of the connecting housing 44, for example, the first sub-housing 411. In some embodiments, the retaining plate 4117 may be omitted.

[0170] In some embodiments, the abutment portion 413 may be disposed adjacent to the enclosure 4117.

[0171] In some embodiments, the gear teeth 7212 may extend toward the side of the first camera 50, such as the camera body 51, to surround the enclosure 4117, or they may surround the bearing 52, thereby balancing the force on the bearing 52 and minimizing the radial clearance of the bearing 52.

[0172] In some embodiments, the extended gear teeth 7212 may also engage with the abutment portion 413, thereby reducing the protrusion height of the abutment portion 413 and making the connecting housing 44 thinner.

[0173] In some embodiments, the extended gear teeth 7212 can also make the structure of the gear 721 cooperating with the first camera 50 more compact, so that the thickness of the connecting housing 44 does not increase due to the setting of the gear 721, thereby making the connecting housing 44 thinner and lighter.

[0174] In some embodiments, the bearing 52 may not be part of the first camera 50. In some embodiments, the gear 721 may be part of the first camera 50, thereby omitting the transmission assembly 72.

[0175] Please see Figure 16 and Figure 19 The clearance control member 80 may be disposed within the camera housing 40, for example, the connecting housing 44. In some embodiments, the clearance control member 80 may be disposed on the first sub-housing 411. The clearance control member 80 may elastically abut against the side peripheral surface of the first camera 50 to press the first camera 50 against the hole wall of the first mounting hole 4111, thereby controlling the clearance of the first camera 50 at the first mounting hole 4111.

[0176] In some embodiments, the clearance control member 80 may include a rotating member 81 and an elastic member 82. The rotating member 81 is rotatably connected to the camera housing 40, for example, the connecting housing 44, and abuts against the side peripheral surface of the first camera 50. The elastic member 82 is mounted on the camera housing 40, for example, the connecting housing 44, and connected to the rotating member 81. Under the elastic deformation of the elastic member 82, the rotating member 81 abuts against the side peripheral surface of the first camera 50, thereby controlling the clearance of the first camera 50 at the first mounting hole 4111.

[0177] In some embodiments, the rotating member 81 may have an abutting end 812 and a connecting end 811. The elastic member 82 may be connected to the connecting end 811, thereby causing the abutting end 812 to elastically abut against the side peripheral surface of the first camera 50.

[0178] In some embodiments, the clearance control member 80, such as the rotating member 81, may elastically abut against the toothless region 7202 to press the camera body 51 against the wall of the first mounting hole 4111.

[0179] In some embodiments, the clearance control member 80, such as the rotating member 81, may elastically abut against the toothless region 7202 to control the radial clearance of the bearing 52.

[0180] In some embodiments, the toothless region 7202 has a contact point 73 in the rotational direction of the gear 721 that contacts the clearance control member 80, such as the rotating member 81. In some embodiments, the contact point 73 may abut against the rotating member 81, such as the abutment end 812.

[0181] In some embodiments, the contact point 73 may include a first contact point 731, a second contact point 732, and a third contact point 733 located between the first contact point 731 and the second contact point 732. The contact point 73 gradually increases in perpendicular distance from the first rotation axis along the path from the first contact point 731 to the second contact point 732. This allows the rotating member 81 to rotate, further increasing the elastic deformation of the elastic member 82, and consequently strengthening the abutting force of the rotating member 81, for example, its abutting end 812, at the contact point 73. This further allows the rotating member 81, for example, its abutting end 812, to tend to move from the second contact point 732 to the first contact point 731.

[0182] Since the gear teeth 7212 are only distributed in the toothed area 7201, there is a possibility that the drive assembly 71 may disengage from the gear 721. Furthermore, in a further embodiment, the first contact point 731 and the second contact point 732 allow the clearance control member 80, such as the rotating member 81, to slide in the toothless area 7202 along the direction from the second contact point 732 to the first contact point 731, thereby driving the gear 721 to rotate until it engages with the drive assembly 71.

[0183] In some embodiments, the elastic member 82 may be made of an elastic material. In some embodiments, the clearance control member 80 may also be configured in the same manner as the elastic fastener 16, that is, the clearance control member 80 may include an elastic member. The elastic member may have a fixed end and a free end. The fixed end is fixed to the camera housing 40, for example, the connecting housing 44, and the free end or the portion of the elastic member 82 between the free end and the fixed end elastically abuts against the side peripheral surface of the first camera 50 to press the first camera 50 against the wall of the first mounting hole 4111. In some embodiments, the elastic member may be fixed to the first sub-housing 411.

[0184] In some embodiments, the elastic fastener 16 can be configured as a clearance control member 80, that is, the elastic fastener 16 can also include a rotating member and an elastic member. The rotating member is rotatably connected to the fixed base 10, such as the fixed body 11. One end of the elastic member is connected to the fixed base 10, such as the fixed body 11, and the other end is connected to the rotating member. The locking part 161 is disposed on the rotating member.
