Description

[Technical Field]

[0001] The present application relates to the technical field of electronic devices, and more particularly to electronic devices and expansion assemblies. [Background technology]

[0002] Cameras are widely used in people's daily lives. For example, cameras can be used in environments such as roads, campuses, and indoor environments to implement functions such as imaging. With the development of science and technology and the continuous improvement of people's needs, users expect cameras to have richer functions. For example, some users expect cameras to have wireless communication functions; and some users expect cameras to have functions such as face recognition or vehicle license plate recognition. To meet different needs of different users, required functional circuits (e.g., communication circuits or processors) can be added to cameras. However, in actual applications, the required functional circuits are usually installed in cameras before delivery, but cannot be installed after delivery or at the application site. As a result, the functions of the cameras are incomplete or redundant.

[0003] The present application provides an electronic device and expansion assembly that can facilitate flexible expansion and installation.

[0004] According to one aspect, the present application provides an electronic device including a primary device assembly and an expansion assembly. The primary device assembly includes a first housing and a primary body circuit, the first housing having a first receiving cavity, the primary body circuit disposed within the first receiving cavity. The expansion assembly includes a second housing and an expansion circuit, the second housing having a second receiving cavity, the expansion circuit disposed within the second receiving cavity, the expansion circuit signal-connected to the primary body circuit to expand or enhance functionality of the primary device assembly. To facilitate quick installation and disassembly between the expansion assembly and the primary device assembly, the first housing has a first mounting structure, and the second housing has a second mounting structure, the first mounting structure detachably connected to the second mounting structure to facilitate detachable connection between the expansion assembly and the primary device assembly.

[0005] In a particular implementation, the type and number of expansion circuits included in the expansion assembly may vary. For example, the expansion circuit may be a communication circuit, such as a radar, a Wi-Fi module, a 4G communication module, a 5G communication module, or a Bluetooth module, or may be a device, such as a graphics processing unit, an AI processing chip, or a memory.

[0006] During actual application, required expansion circuits may be installed in the expansion assembly before delivery or at the manufacturing site, thereby achieving greater flexibility and avoiding disadvantageous problems such as incomplete or redundant functions. In addition, when the expansion circuits are installed, the primary device assembly does not need to be disassembled or assembled, thereby preventing the airtightness of the primary device assembly from being affected.

[0007] In a specific configuration, the first mounting structure may include a slot arranged along a first direction, and the second mounting structure may include a tongue arranged along the first direction. Specifically, the tongue may be inserted into the slot along the first direction to implement a fixed connection between the first housing and the second housing. When the expansion assembly and the primary device assembly are assembled, quick installation and disassembly between the expansion assembly and the primary device assembly may be implemented through mutual plugging and mating between the tongue and the slot. In addition, the disassembly and assembly steps are simple, which helps improve the convenience and efficiency of the disassembly and assembly.

[0008] In one implementation, to improve the stability of the connection between the expansion assembly and the primary device assembly, the detachable connection between the expansion assembly and the primary device assembly can be further implemented by using another connection structure.

[0009] For example, the first connection hole may be provided with a first housing, and the second connection hole may be provided with a second housing, and the first connection hole and the second connection hole are connected by using a fastener.

[0010] In a specific arrangement, the first connecting hole may be a threaded hole, the second connecting hole may be a through hole, and the fastener may be a bolt. During installation, to implement a detachable connection between the first connecting hole and the second connecting hole, the fastener may be inserted from one end of the second connecting hole and then threadedly connected to the first connecting hole.

[0011] In addition, in another implementation, the specific types of the first connecting hole, the second connecting hole, and the fastener can be adaptively adjusted based on actual requirements. For example, the first connecting hole and the second connecting hole can alternatively be pin holes, etc., and the fastener can correspondingly be pins, etc.

[0012] In a specific configuration, in order to improve the effect of the connection between the first housing and the second housing, the arrangement direction of the tongue (or slot) and the arrangement direction of the first connection hole (or second connection hole) may be arranged at an included angle.

[0013] Specifically, both the tongue and the slot are arranged along a first direction, and both the first connecting hole and the second connecting hole are provided along a second direction. After the tongue is inserted into the slot, a position limit may be formed on the first housing and the second housing in the second direction, thereby preventing the second housing from generating a position offset relative to the first housing in the second direction. After the fastener is fixedly connected to the first connecting hole and the second connecting hole, the position limit may be formed on the first housing and the second housing in the first direction to effectively prevent the second housing from generating a position offset relative to the first housing in the first direction, effectively improve the relative stability between the first housing and the second housing, and avoid a position offset between the first housing and the second housing. In addition, the mutual fit between the tongue and the slot can form a positional limit on the first housing and the second housing in the second direction, so that disadvantageous problems, such as loosening between the fastener and the first connecting hole or loosening between the fastener and the second connecting hole, can be avoided to a certain extent.

[0014] In a specific configuration, the angle between the first direction and the second direction can be appropriately set based on different circumstances. Specifically, the angle between the first direction and the second direction can be 0° to 90°.

[0015] Additionally, to facilitate a signal connection between the primary device assembly and the expansion assembly, the primary device assembly may further include a first connector, and the expansion assembly may further include a second connector. When the expansion assembly and the primary device assembly are assembled, the signal connection between the primary device assembly and the expansion assembly may be implemented through docking between the first connector and the second connector.

[0016] In certain configurations, the first connector and the second connector can be plugged in a second orientation to improve convenience and reliability of installation between the primary device assembly and the expansion assembly. The first housing includes a housing body and a bracket.

[0017] In some implementations, the first housing may include a housing body and a bracket, the housing body being detachably connected to the bracket.

[0018] In a particular configuration, the first receiving cavity may be disposed within the housing body; and the first mounting structure may be disposed on the housing body or the bracket.

[0019] According to another aspect, the present application further provides an extension assembly configured with a shielding cover assembly, which can be disposed on the top and sides of the second housing in a covering manner to provide good shielding effect on the second housing and prevent the second housing from being affected by exposure to the sun, rain, sand or dust, etc.

[0020] In a specific configuration, the shielding cover assembly may include a shielding cover body for covering the outer periphery of the second housing. The shielding cover body may be fixedly connected to the second housing in a clamping manner. A clamp hook may be disposed on the second housing, and the shielding cover body may be provided in a slot, and a quick connection between the shielding cover body and the second housing may be implemented through clamping and engagement between the clamp hook and the slot.

[0021] To facilitate removal of the shielding cover body from the second housing, the shielding cover assembly may further include a button. A user can press the button to separate the clamp hook from the slot and separate the shielding cover body from the second housing. In a specific configuration, the button may include a pressing portion for manual operation and a pressing portion for pressing the clamp hook. When the shielding cover assembly is to be removed from the second housing, a user's hand acts on the pressing portion of the button to press the button. The pressing portion of the button presses the clamp hook, causing the clamp hook to elastically deform and separate from the slot, thereby facilitating removal of the shielding cover assembly from the second housing.

[0022] In addition, to ensure that the button can be positioned on the correct movement path when pressed, a positioning rod may be further arranged for the button, and a shielding cover body may be provided in the slide hole, and the positioning rod may be slidably arranged in the slide hole. When pressure is applied to the button by hand, the button may slide along the length direction of the positioning rod (or slide hole), so that the use effect of the button can be effectively improved.

[0023] In addition, the shielding cover assembly may further include a return spring to enable the button to automatically return to a position that would be used if the button were not pressed after being pressed. One end of the return spring is connected to the button and the other end is connected to the shielding cover body. The return spring is configured to apply a force to the button in a direction opposite to the pressing direction.

[0024] Additionally, the present application further provides an expansion assembly that can be configured to adjust the orientation of an expansion circuit, the expansion assembly including a rotation assembly, the expansion circuit connected to the second housing using the rotation assembly, and the rotation assembly configured to drive and rotate the expansion circuit to change the orientation or position of the expansion circuit.

[0025] In a specific configuration, the rotating assembly may include a motor having a stator fixed on the second housing and a rotor fixedly connected to the expansion circuit, and when the rotor rotates, the orientation of the expansion circuit may change, thereby improving the performance of the expansion circuit.

[0026] According to another aspect, the present application further provides an expansion assembly configured to be detachably connected to a primary device assembly, the expansion assembly including an expansion circuit and a housing, and the expansion circuit electrically connected to a primary body circuit in the primary device assembly.

[0027] In one implementation, a shielding cover assembly may be mounted on the extension assembly, and the shielding cover assembly may be disposed on the top and sides of the housing in a covering manner to provide good shielding effect on the housing and prevent the housing from being affected by sun exposure, rain, sand or dust, etc.

[0028] In a specific configuration, the shielding cover assembly may include a shielding cover body for covering the outer periphery of the housing. The shielding cover body may be fixedly connected to the housing in a clamping manner. A clamp hook may be disposed on the housing, and the shielding cover body may be provided in a slot, and a quick connection between the shielding cover body and the housing may be implemented through clamping and engagement between the clamp hook and the slot.

[0029] To facilitate removal of the shielding cover body from the housing, the shielding cover assembly may further include a button. A user can press the button to separate the clamp hook from the slot and separate the shielding cover body from the housing. In a specific configuration, the button may include a pressing portion for manual operation and a pressing portion for pressing the clamp hook. When the shielding cover assembly is to be removed from the housing, a person's hand acts on the pressing portion of the button to press the button. The pressing portion of the button presses the clamp hook, causing the clamp hook to elastically deform and separate from the slot, thereby facilitating removal of the shielding cover assembly from the housing.

[0030] In addition, to ensure that the button can be positioned on the correct movement path when pressed, a positioning rod may be further arranged for the button, and a shielding cover body may be provided in the slide hole, and the positioning rod may be slidably arranged in the slide hole. When pressure is applied to the button by hand, the button may slide along the length direction of the positioning rod (or slide hole), so that the use effect of the button can be effectively improved.

[0031] In addition, the shielding cover assembly may further include a return spring to enable the button to automatically return to a position that would be used if the button were not pressed after being pressed. One end of the return spring is connected to the button and the other end is connected to the shielding cover body. The return spring is configured to apply a force to the button in a direction opposite to the pressing direction.

[0032] Additionally, the present application further provides an expansion assembly that can be configured to adjust the orientation of an expansion circuit, the expansion assembly including a rotation assembly, the expansion circuit connected to the housing using the rotation assembly, and the rotation assembly configured to drive and rotate the expansion circuit to change the orientation or position of the expansion circuit.

[0033] In certain configurations, the rotating assembly may include a motor having a stator fixed on the housing and a rotor fixedly connected to the expansion circuit, and when the rotor rotates, the orientation of the expansion circuit may change, thereby improving the performance of the expansion circuit.

[0034] In certain applications, the primary device assembly may be a camera or an outdoor base station (e.g., a base station configured to receive and transmit wireless signals), etc. The type of the primary device assembly is not limited in this application. [Brief explanation of the drawings]

[0052] To make the objectives, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings.

[0053] To facilitate understanding of the expansion assembly provided in one embodiment of the present application, an application scenario of the expansion assembly is first described below.

[0054] The expansion assemblies provided herein can be used in a primary device assembly, such as a camera or an outdoor base station, to expand and improve the functionality of the corresponding primary device assembly. A camera is used as an example. A camera generally includes a lens assembly, which is configured to implement an image information collection function. Currently, some manufacturers typically add an additional processor to a camera to enable the camera to have information processing capabilities (such as facial recognition or vehicle license plate recognition). However, to ensure the hermeticity of the lens assembly, the processor can only be installed before the camera is delivered. Therefore, the installation of the processor cannot be properly adjusted at the manufacturing site. In addition, some manufacturers typically add a wireless communication circuit to a camera to enable the camera to have a wireless communication function. However, in practical applications, to meet the heat dissipation requirements of the camera, the camera usually uses a metal housing, such as an aluminum alloy housing. Therefore, to prevent the signal of the wireless communication circuit from being blocked by the metal housing, the wireless communication circuit can only be installed on the camera housing, but not inside the camera. If the wireless communication circuit is installed on the housing, it occupies a portion of the housing's area, thereby reducing the heat dissipation of the camera. In addition, during practical application, the wireless communication circuit needs to be connected to the camera body by using a cable, and the position where the cable is connected to the camera body needs to be sealed to ensure the hermeticity of the lens assembly. In addition, after the sealing is completed, a hermeticity test also needs to be performed on the lens assembly. Therefore, the installation of the wireless communication circuit can only be performed before delivery, but cannot be performed at the manufacturing site (or after the camera is delivered). As a result, there is a significant limitation.

[0055] In actual applications, cameras have multiple different application scenarios, and different users have different functional requirements for cameras, so the types and number of functional circuits added to cameras also vary greatly. However, due to the airtightness requirements of the lens assembly (or camera), the functional circuits installed in the camera can only be configured before delivery. This may cause incomplete or redundant functions during actual applications. It can be understood that the above-mentioned cameras include, but are not limited to, types such as spherical cameras, hemispherical cameras, and barrel cameras. In addition, the above uses cameras as an example for simple explanation. However, in actual applications, when functional circuits are installed in a primary device assembly, such as an outdoor base station (e.g., a base station configured to receive and transmit wireless signals), the primary device assembly also faces the same or similar technical problems as those of the above-mentioned camera.

[0056] Therefore, embodiments of the present application provide an expansion assembly that can be implemented for flexible and rapid installation, and an electronic device equipped with the expansion assembly.

[0057] To make the objectives, technical solutions and advantages of the present application clearer, the following further describes the present application in detail with reference to the accompanying drawings and specific embodiments.

[0058] The terms used in the following embodiments are intended to describe specific embodiments only and are not intended to limit the present application. As used in this specification and the appended claims, the singular terms "one," "a," and "this" are intended to include expressions such as "one or more," unless the context clearly dictates otherwise. It should be further understood that in the following embodiments, "at least one" and "one or more" refer to one, two, or more. The term "and / or" describes a correspondence relationship for describing related objects, and indicates that three relationships may exist. For example, A and / or B may represent the cases where only A is present, where both A and B are present, and where only B is present. A and B may be singular or plural. The character " / " typically indicates an "or" relationship between related objects.

[0059] References to "one embodiment" or "some embodiments" or the like described herein mean that a particular feature, structure, or characteristic described with reference to one or more embodiments is included in one or more embodiments of the present application. Thus, statements such as "in one embodiment," "in some embodiments," "in some other embodiments," and "in other embodiments" appearing in different places in this specification do not necessarily refer to the same embodiment. Instead, these statements mean "one or more, but not all, of several embodiments," unless specifically emphasized otherwise. The terms "include," "have," and variations thereof all mean "including, but not limited to," unless specifically emphasized otherwise.

[0060] 1 , one embodiment of the present application provides an electronic device including a primary device assembly 10 and an expansion assembly 20. The primary device assembly 10 includes a first housing 11 and a primary body circuit 12, where the first housing 11 has a first receiving cavity 1111 and the primary body circuit 12 is disposed within the first receiving cavity 1111. The expansion assembly 20 includes a second housing 21 and an expansion circuit 22. The second housing 21 has a second receiving cavity 211 and the expansion circuit 22 is disposed within the second receiving cavity 211, where the expansion circuit 22 is signal-connected to the primary body circuit 12 to expand or improve the functionality of the primary device assembly 10. In order to implement quick installation and disassembly between the expansion assembly 20 and the primary device assembly 10, the first housing 11 has a first installation structure (not shown in the figure), and the second housing 21 has a second installation structure (not shown in the figure), and the first installation structure is detachably connected to the second installation structure in order to implement a detachable connection between the expansion assembly 20 and the primary device assembly 10.

[0061] In a specific implementation, the type and number of expansion circuits 22 included in the expansion assembly 20 may vary. For example, the expansion circuit 22 may be a communication circuit, such as a radar, a Wi-Fi module, a 4G communication module, a 5G communication module, or a Bluetooth module, or may be a device, such as a graphics processing unit, an AI processing chip, or a memory. During actual application, the required expansion circuit 22 may be installed in the expansion assembly 20 before delivery or at the manufacturing site, thereby achieving greater flexibility and avoiding disadvantageous problems such as incomplete or redundant functions. In addition, when the expansion circuit 22 is installed, the primary device assembly 10 does not need to be disassembled or assembled, and therefore the hermeticity of the primary device assembly 10 is not affected.

[0062] In a particular implementation, the specific structure and configuration of the expansion assembly 20 and the primary device assembly 10 may vary.

[0063] 1 , in the embodiment provided herein, the first housing 11 includes a housing body 111 and a bracket 112. The first accommodating cavity 1111 is located within the housing body 111. The bracket 112 is configured to fix the housing body 111 at an installation position (e.g., on a wall or a road monitoring pole) and can further be detachably connected to the second housing 21. That is, the housing body 111 is detachably connected to the second housing 21 by using the bracket 112. It can be understood that in another implementation, the second housing 21 can alternatively be directly and fixedly connected to the housing body 111.

[0064] During practical application, if the function of the primary device assembly 10 needs to be extended or improved, the required extension assembly 20 can be installed on the primary device assembly 10 by using the first installation structure and the second installation structure.

[0065] 2 , in one embodiment provided herein, the first mounting structure includes a slot 1121 provided along the first direction; and the second mounting structure includes a tongue 212 arranged along the first direction. Specifically, the tongue 212 can be inserted into the slot 1121 along the first direction to implement a fixed connection between the bracket 112 and the second housing 21. When the expansion assembly 20 and the primary device assembly 10 are assembled, quick installation and disassembly between the expansion assembly 20 and the primary device assembly 10 can be implemented through mutual plugging and fitting between the tongue 212 and the slot 1121. In addition, the disassembly and assembly steps are simple, which helps to improve the convenience and efficiency of the disassembly and assembly.

[0066] In a specific implementation, the contours of the tongue 212 and the slot 1121 may be substantially the same, thereby improving the relative stability between the tongue 212 and the slot 1121. For example, when the tongue 212 has a rectangular sheet-shaped structure, the slot 1121 may alternatively have a rectangular groove-shaped structure. After the tongue 212 is inserted into the slot 1121, the side of the tongue 212 may abut against the inner wall of the slot 1121, or a small gap may be maintained between the side of the tongue 212 and the inner wall of the slot 1121, to prevent an unfavorable situation, such as the tongue 212 obviously wobbling in the slot 1121. It may be understood that in another implementation, the tongue 212 may alternatively have a plate-shaped structure having a contour, such as a semicircular or triangular shape. Correspondingly, the slot 1121 may alternatively have a groove-shaped structure having a contour, such as a semicircular or triangular shape.

[0067] In some implementations, the tongue 212 and the slot 1121 may alternatively be assembled in an interference fit manner. For example, the size of the tongue 212 may be slightly larger than the size of the slot 1121, so that when the tongue 212 is inserted into the slot 1121, a tight fit is formed between the tongue 212 and the inner wall of the slot 1121, preventing undesirable situations such as loosening.

[0068] During manufacturing, the tongue 212 and the second housing 21 may be two independent mechanical parts or may be an integrated mechanical part. Specifically, if the tongue 212 and the second housing 21 are two independent mechanical parts, the tongue 212 and the second housing 21 may be manufactured and formed separately, and the tongue 212 is installed on the second housing 21 through welding or by using fasteners such as screws. If the tongue 212 and the second housing 21 are an integrated mechanical part, the tongue structure may be formed directly on the second housing 21 through injection molding or the like.

[0069] It can be seen that in the above-described embodiment, the tongue 212 is disposed on the second housing 21, and the bracket 112 is provided in the slot 1121. In another implementation, the position of the tongue 212 can alternatively be interchanged with the position of the slot 1121. That is, the tongue 212 can be disposed on the bracket 112, and the second housing 21 can be provided in the slot 1121.

[0070] In addition, in a specific arrangement, the number of tongues 212 may be two or more. Correspondingly, the number of slots 1121 may alternatively be adaptively adjusted based on the number of tongues 212. This is not specifically limited in the present application.

[0071] In order to improve the stability of the connection between the expansion assembly 20 and the primary device assembly 10 during certain configurations, a detachable connection between the expansion assembly 20 and the primary device assembly 10 may be implemented by using a different connection structure.

[0072] For example, as shown in FIG. 3, in one embodiment provided in the present application, the first connecting hole 1122 is provided with a bracket 112, the second connecting hole 213 is provided with a second housing 21, and the first connecting hole 1122 and the second connecting hole 213 are connected using a fastener 30.

[0073] In a specific arrangement, the first connecting hole 1122 may be a threaded hole, the second connecting hole 213 may be a through hole, and the fastener 30 may be a bolt. During installation, to implement a detachable connection between the first connecting hole 1122 and the second connecting hole 213, the fastener 30 may be inserted from the top end of the second connecting hole 213 and threadedly connected to the first connecting hole 1122.

[0074] 2 and 3 , during installation, the tongue 212 can be first inserted into the slot 1121 to implement a relative fixation between the bracket 112 and the second housing 21. Then, the fastener 30 is inserted into the first connecting hole 1122 and the second connecting hole 213 to implement a fixed connection between the first connecting hole 1122 and the second connecting hole 213, thereby implementing a fixed connection between the bracket 112 and the second housing 21.

[0075] In a particular configuration, in order to improve the connection effect between the bracket 112 and the second housing 21, the arrangement direction of the tongue 212 (or slot 1121) and the arrangement direction of the first connection hole 1122 (or second connection hole 213) may be arranged at an included angle.

[0076] For example, in the embodiment provided herein, both the tongue 212 and the slot 1121 are arranged along a first direction, and both the first connecting hole 1122 and the second connecting hole 213 are arranged along a second direction, and the first direction and the second direction are perpendicular to each other. After the tongue 212 is inserted into the slot 1121, a position limit is formed on the second housing 21 and the bracket 112 in the second direction, which can prevent the second housing 21 from generating a position offset with respect to the bracket 112 in the second direction. After the fastener 30 is configured to be fixedly connected to the first connecting hole 1122 and the second connecting hole 213, in order to effectively prevent the second housing 21 from generating a position offset relative to the bracket 112 in the first direction, in order to effectively improve the relative stability between the second housing 21 and the bracket 112 and to avoid a position offset between the second housing 21 and the bracket 112, a position limit may be formed on the second housing 21 and the bracket 112 in the first direction. In addition, due to the mutual fitting between the tongue 212 and the slot 1121, a position limit may be formed on the second housing 21 and the bracket 112 in the second direction, so that disadvantageous problems, such as loosening between the fastener 30 and the first connecting hole 1122 or loosening between the fastener 30 and the second connecting hole 213, may be avoided to a certain extent.

[0077] In a specific configuration, the angle between the first direction and the second direction can be appropriately set based on different circumstances. Specifically, the angle between the first direction and the second direction can be 0° to 90°.

[0078] It may be understood that in another implementation, the first connecting hole 1122 may be a through-hole structure, and the second connecting hole 213 may be a threaded hole. During installation, to implement a detachable connection between the first connecting hole 1122 and the second connecting hole 213, the fastener 30 may be inserted from one end of the first connecting hole 1122 and then threadedly connected to the second connecting hole 213.

[0079] In addition, in another implementation, the specific types of the first connecting hole 1122, the second connecting hole 213, and the fastener 30 can be adaptively adjusted based on actual requirements. For example, the first connecting hole 1122 and the second connecting hole 213 can alternatively be pin holes, etc., and the fastener 30 can correspondingly be pins, etc.

[0080] 4 , to facilitate a signal connection between the primary device assembly 10 and the expansion assembly 20, the primary device assembly 10 may further include a first connector 1123, and the expansion assembly 20 may further include a second connector 214. When the expansion assembly 20 and the primary device assembly 10 are assembled, the signal connection between the primary device assembly 10 and the expansion assembly 20 may be implemented through docking between the first connector 1123 and the second connector 214.

[0081] Specifically, in one embodiment provided herein, the first connector 1123 is disposed on the bracket 112, and a lower end of the first connector 1123 is electrically connected to the primary body circuit 12. The second connector 214 is disposed on the second housing 21, and an upper end of the second connector 214 is electrically connected to the expansion circuit 22. After the first connector 1123 is docked with the second connector 214, a signal connection between the primary body circuit 12 and the expansion circuit 22 can be implemented.

[0082] In certain configurations, the first connector 1123 can be plugged into the second connector 214 in the second orientation. When the expansion assembly 20 is installed on the primary device assembly 10, both a fixed connection between the expansion assembly 20 and the primary device assembly 10 and docking between the first connector 1123 and the second connector 214 can be implemented.

[0083] 4 to 6 , during installation, a relative tilted attitude may be maintained between the expansion assembly 20 and the primary device assembly 10, so that the insertion end of the tongue 212 is positioned at the opening of the slot 1121. The expansion assembly 20 is pressed downward, so that the tongue 212 is gradually inserted into the slot 1121 and the first connector 1123 is gradually docked with the second connector 214. After the tongue 212 is fully inserted into the slot 1121, the first connector 1123 is docked with the second connector 214, and the first connecting hole 1122 and the second connecting hole 213 remain coaxially aligned. Finally, the fastener 30 is inserted into the first connecting hole 1122 and the second connecting hole 213, so that the first connecting hole 1122 and the second connecting hole 213 are fixedly connected. Finally, the assembly between the expansion assembly 20 and the primary device assembly 10 is implemented.

[0084] In the aforementioned implementation, quick installation between the expansion assembly 20 and the primary device assembly 10 can be implemented through plug connection and engagement between the tongue 212 and the slot 1121, and engagement between the first connecting hole 1122 and the second connecting hole 213. In addition, during assembly, docking between the first connector 1123 and the second connector 214 can be implemented to implement signal connection between the expansion assembly 20 and the primary device assembly 10. The simplicity of the installation stage facilitates improved convenience and efficiency of assembly.

[0085] In some implementations, to ensure the structural safety of the tongue 212 and prevent adverse situations, such as breakage of the tongue 212, the tongue 212 may have elasticity. When the expansion assembly 20 and the primary device assembly 10 maintain a relative tilted posture for assembly, the tongue 212 can better match with the slot 1121 through elastic deformation of the tongue 212, thereby effectively improving the installation effect and structural safety.

[0086] In a particular arrangement, the housing body 111 and the bracket 112 may be connected in a variety of ways.

[0087] 7 , in the embodiment provided herein, housing body 111 is rotatably and adjustably disposed on bracket 112. That is, housing body 111 can rotate relative to bracket 112. Lens assembly 110 is installed within housing body 111. To change and increase the imaging range of lens assembly 110, the orientation of lens assembly 110 can be adjusted by adjusting the rotation angle of housing body 111.

[0088] Specifically, the housing body 111 includes a base 1112 and a connecting plate 1113 , and the base 1112 and the connecting plate 1113 are fixedly connected to each other by using screws 31 .

[0089] Three through holes (not shown) are provided in the connection plate 1113. Three screw holes (not shown) are provided on the surface (top surface) of the base 1112 facing the connection plate 1113. The three through holes are provided in one-to-one correspondence with the three screw holes. After three screws 31 are respectively passed through the corresponding through holes and the corresponding screw holes and fixed into the corresponding through holes and the corresponding screw holes, a fixed connection between the connection plate 1113 and the base 1112 can be implemented.

[0090] It can be understood that in other implementations, the number and positions of the through holes and the number and positions of the screw holes can be adaptively adjusted based on different requirements. Alternatively, the connecting plate 1113 and the base 1112 can be fixedly connected in some manner, for example, through a clamp or through welding. This is not limited in the present application.

[0091] To implement rotatable adjustment between the housing body 111 and the bracket 112,

[0092] As shown in Figure 8, a bracket 112 is provided in a through hole 1124 provided along the second direction, and a convex shaft 11131 arranged along the second direction is placed on the connecting plate 1113, and the convex shaft 11131 is inserted into the through hole 1124, so that the connecting plate 1113 can rotate around the axis of the convex shaft 11131 (or the through hole 1124) as the center of rotation.

[0093] The first friction surface 1126 disposed below is disposed on the bottom of the bracket 112, the second friction surface 11132 disposed above is disposed on the connecting plate 1113, and the friction ring 13 is disposed between the first friction surface 1126 and the second friction surface 11132. After the upper surface of the friction ring 13 is attached to the first friction surface 1126, the lower surface of the friction ring 13 is attached to the second friction surface 11132, so that the connecting plate 1113 can be prevented from rotating relative to the bracket 112 under the action of a friction force. When the first friction surface 1126 is out of contact with the friction ring 13 or the second friction surface 11132 is out of contact with the friction ring 13, the connecting plate 1113 can be rotated manually, so that the connecting plate 1113 rotates relative to the bracket 112.

[0094] Additionally, in order to enable the first friction surface 1126 and the friction ring 13 to maintain an attached state under normal conditions, and to enable the second friction surface 11132 and the friction ring 13 to maintain an attached state, in the embodiment provided in the present application, a compression spring 14 is further disposed between the bracket 112 and the connecting plate 1113.

[0095] Please refer to both Figures 8 and 9. Specifically, an inwardly extending flange 1125 is disposed on the inner wall of the through hole 1124, a retaining ring 11133 is installed on the upper part of the convex shaft 11131, and a compression spring 14 is sleeve-connected to the outer periphery of the convex shaft 11131. The upper end of the compression spring 14 abuts against the lower surface of the retaining ring 11133, and the lower end of the compression spring 14 abuts against the flange 1125. In other words, the compression spring 14 is disposed between the connecting plate 1113 and the bracket 112 to apply an upward elastic force to the retaining ring 11133. Since the retaining ring 11133 is fixedly connected to the connecting plate 1113, the compression spring 14 can exert an upward elastic force on the connecting plate 1113 to press the friction ring 13 between the first friction surface 1126 and the second friction surface 11132, so that the first friction surface 1126 and the friction ring 13 remain attached, and the second friction surface 11132 and the friction ring 13 remain attached. When the rotation angle of the connecting plate 1113 (or the housing body 111) needs to be adjusted, a person's hand acts on the connecting plate 1113 (or the housing body 111) to lift the connecting plate 1113, so that the first friction surface 1126 is out of contact with the friction ring 13, and the second friction surface 11132 is out of contact with the friction ring 13. In this way, the connecting plate 1113 (or the housing main body 111) can be easily rotated, and as a result, the rotation angle of the connecting plate 1113 (or the housing main body 111) can be adjusted.

[0096] In a specific configuration, the friction ring 13 may be a ring-shaped structure made of a material such as silicone or foam, so that a large coefficient of friction exists between the friction ring 13 and the first friction surface 1126 and between the friction ring 13 and the second friction surface 11132. In addition, the friction ring 13 can also have a shock-absorbing effect, which can effectively reduce the shock transmission between the connecting plate 1113 and the bracket 112.

[0097] During installation, the friction ring 13 may first be sleeve-connected onto the outer periphery of the convex shaft 11131, the convex shaft 11131 passes through the through-hole, and the compression spring 14 is sleeve-connected onto the outer periphery of the convex shaft 11131. Finally, the retaining ring 11133 is fixed to the top of the convex shaft 11131 by using the screw 32 to implement a fixed connection between the retaining ring 11133 and the convex shaft 11131, and the compression spring 14 is pressed between the retaining ring 11133 and the flange 1125.

[0098] It can be understood that in another implementation, roughening can be further performed on the first friction surface 1126 and the second friction surface 11132 to increase the friction between the first friction surface 1126 and the friction ring 13, and between the second friction surface 11132 and the friction ring 13. In a specific configuration, in addition to a ring-shaped structure, the friction ring 13 can be arranged in a sheet-shaped structure, a block-shaped structure, or the like. The specific shape and material of the friction ring 13 are not limited in this application. Alternatively, in another implementation, the friction ring 13 can be omitted, so that the first friction surface 1126 directly contacts the second friction surface 11132. Alternatively, to improve the locking effect between the connecting plate 1113 and the bracket 112, interlocking tooth structures can be arranged on the first friction surface 1126 and the second friction surface 11132.

[0099] In a particular arrangement, the shape and configuration of the expansion assembly 20 may alternatively vary.

[0100] 10 and 11, in one embodiment provided herein, the second housing 21 includes two parts: an inner housing 215 and an outer housing 216. The outer housing 216 is sleeve-connected to the outer periphery of the inner housing 215, so that the inner housing 215 and the outer housing 216 enclose a second accommodating cavity 211 for installing the expansion circuit 22.

[0101] Specifically, the inner housing 215 is constructed as a hollow structure. The cross section of the inner contour is circular, and the cross section of the outer contour is quadrilateral. The space enclosed by the inner contour forms a vertically connected ventilation channel 217. The expansion circuit 22 may be fixedly connected to the quadrilateral side of the inner housing 215, and the heat dissipation element in the expansion circuit 22 may be thermally connected to the inner housing 215 using a medium such as thermally conductive silicone, so that the heat generated by the heat dissipation element can be effectively transferred to the inner housing 215 for heat dissipation.

[0102] In certain implementations, multiple extension circuits 22 may be arranged, and the multiple extension circuits 22 may be arranged on different surfaces of the inner housing 215. For example, if the number of arranged extension circuits 22 is four, the four extension circuits 22 may be distributed on the four side surfaces of the inner housing 215. It can be understood that in other implementations, the number and positions of the arranged extension circuits 22 may be adaptively adjusted based on actual conditions. In addition, the shape contour of the inner housing 215 may alternatively have another shape structure. For example, the cross section of the inner contour of the inner housing 215 may have a circular structure, an elliptical structure, a square structure, or another polygonal structure. The cross section of the outer contour may have a circular structure, an elliptical structure, a square structure, or another polygonal structure. In addition, the shape of the cross section of the inner contour and the shape of the cross section of the outer contour of the inner housing 215 may be the same or different. For example, both the cross sections of the inner and outer contours of the inner housing 215 may be circular. Alternatively, the inner profile within the inner housing 215 has a circular cross section and the outer profile has a square cross section.

[0103] According to another aspect, an embodiment of the present application further provides an expansion assembly 20 that can be configured to adjust the orientation of the expansion circuit 22 .

[0104] 12 and 13, in one embodiment provided herein, the outer housing 216 is buckled onto the top surface of the inner housing 215, thereby enclosing the second accommodating cavity 211. A rotating assembly (not shown) is further disposed within the expansion assembly 20, and the expansion circuit 22 is fixed within the second accommodating cavity 211 by using the rotating assembly.

[0105] Specifically, the rotating assembly includes a motor 218. A stator of the motor 218 is fixed on the inner housing 215, and a rotor is fixedly connected to the expansion circuit 22. When the rotor rotates, the orientation of the expansion circuit 22 may change, thereby improving the performance of the expansion circuit 22. For example, if the expansion circuit 22 includes a device such as a Wi-Fi module or a radio frequency module, the propagation direction of the electromagnetic waves may be adjusted by adjusting the orientation of the Wi-Fi module or the radio frequency module, thereby effectively improving the performance of the expansion circuit 22.

[0106] In a specific configuration, the rotation direction of the expansion circuit 22 can be set correspondingly based on different requirements. For example, in the embodiment provided herein, the motor 218 is disposed vertically, so that the expansion circuit 22 can rotate around the rotation center of the motor. It can be understood that in a specific configuration, the motor 218 can alternatively be disposed diagonally or horizontally.

[0107] Additionally, in another implementation, a transmission connection may be implemented between the output shaft of the motor 218 and the expansion circuit 22 using a transmission mechanism, such as a belt, gear, or chain, so that the motor 218 can drive and rotate the expansion circuit 22.

[0108] According to another aspect, an embodiment of the present application further provides an extension assembly 20 having a shielding cover assembly 23 configured thereon.

[0109] Specifically, as shown in FIG. 14, in the embodiment of the present application, in order to provide a good shielding effect on the second housing 21 and to prevent the second housing 21 from being affected by exposure to the sun, rain, sand or dust, etc., the shielding cover assembly 23 may be arranged in a covering manner on the top and sides of the second housing 21.

[0110] In the embodiment provided herein, the shielding cover assembly 23 includes a shielding cover body 231 and an upper cover 232. Specifically, the shielding cover body 231 is constructed as a cylindrical structure, and the upper cover 232 is disposed on the upper end of the shielding cover body 231 to prevent dust, rain, etc. from entering the shielding cover body 231.

[0111] In a particular implementation, the top cover 232 and the shielding cover body 231 may be connected in various ways.

[0112] 15 and 16, in the embodiment provided herein, the top cover 232 and the shielding cover body 231 are fixedly connected in a clamping manner. A downwardly extending clamp hook 2321 is disposed on the lower surface of the top cover 232, and a slot 2311 is provided on the upper surface of the shielding cover body 231. During assembly, the top cover 232 may be disposed on the upper surface of the shielding cover body 231 and pressed downward with force, so that the clamp hook 2321 and the slot 2311 are clamped together. In this manner, assembly between the top cover 232 and the shielding cover body 231 may be implemented.

[0113] It may be understood that in another implementation, the top cover 232 and the shielding cover body 231 may alternatively be fixedly connected through bonding, threaded connection, welding, or the like. Alternatively, in some other implementations, the top cover 232 and the shielding cover body 231 may be of an integrated structure. For example, the top cover 232 and the shielding cover body 231 may be directly molded into an integrated structure by using an injection molding process.

[0114] Additionally, during a particular implementation, the shielding cover body 231 and the second housing 21 may alternatively be connected in multiple ways.

[0115] 15 and 17, in one embodiment provided herein, the shielding cover body 231 and the second housing 21 are alternatively fixedly connected in a clamping manner. An upwardly extending clamp hook 219 is disposed on the top of the second housing 21, and a slot 2312 is provided on the underside of the shielding cover body 231. The clamp hook 219 and the slot 2312 are clamped and fitted together to implement a quick connection between the shielding cover body 231 and the second housing 21.

[0116] When the shielding cover body 231 is installed on the second housing 21, the shielding cover body 231 may be placed on the second housing 21 in a covering manner, and the shielding cover body 231 may be pressed downward, so that the clamp hook 219 is clamped with the slot 2312, and the connection between the shielding cover body 231 and the second housing 21 may be implemented.

[0117] 15 and 17, in the embodiment provided herein, the shielding cover assembly 23 further includes a button 233 to facilitate removal of the shielding cover body 231 from the second housing 21. A user can press the button 233 to separate the clamp hook 219 from the slot 2312, thereby separating the shielding cover body 231 from the second housing 21.

[0118] Specifically, as shown in FIG. 15, when the shielding cover assembly 23 is removed from the second housing 21, a person's hand acts on the pressing portion 2331 of the button 233, and presses the button 233 downward.

[0119] 17 , the pressing portion 2332 of the button presses the clamp hook 219, causing the clamp hook 219 to elastically deform to the right and separate from the slot 2312. The shielding cover assembly 23 can be removed from the second housing 21 by lifting the shielding cover body 231 upward while pressing and holding the button 233. In the embodiment provided herein, the pressing portion 2332 is configured as a trapezoidal convex structure. It can be understood that in another implementation, the pressing portion 2332 can alternatively be configured as a triangular convex structure or another structure. This is not specifically limited in the present application.

[0120] 16 , to ensure that the button 233 is in the correct movement path when pressed, in the embodiment provided herein, a positioning rod 2333 is further disposed on the bottom of the button 233, and a shielding cover body 231 is provided in the slide hole 2313, and the positioning rod 2333 is slidably disposed in the slide hole 2313. When pressure is applied to the button 233 by hand, the button 233 may slide along the length direction of the positioning rod 2333 (or the slide hole 2313), so that the use effect of the button 233 may be effectively improved.

[0121] Additionally, in the embodiment provided herein, the shielding cover assembly 23 further includes a return spring 234 to enable the button 233 to automatically return to the position that would be used if the button were not pressed after the button 233 has been pressed.

[0122] Specifically, the return spring 234 is sleeved on the outer periphery of the positioning rod 2333, with the upper end of the return spring 234 abutting the bottom surface of the button 233 and the lower end abutting the shielding cover body 231. When the button 233 is pressed downward under the action of an external force, the return spring 234 is compressed and deformed. When the external force is removed, the return spring 234 tends to stretch and pushes the button 233 to move upward, thereby allowing the button 233 to return to the position used when the button is not pressed.

[0123] It can be appreciated that in a particular configuration, the return spring 234 can be in the form of a structure such as a coil spring or a spring plate, for example, which is not specifically limited herein.

[0124] In addition, the number and layout positions of the positioning rods 2333 and the number and layout positions of the slide holes 2313 can be adaptively adjusted based on different requirements.

[0125] The above description is merely a specific implementation of the present application and is not intended to limit the scope of protection of the present application. Any modifications or replacements that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application shall be included in the scope of protection of the present application. Therefore, the scope of protection of the present application shall be subject to the scope of protection of the claims.
