Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, and in particular to an electronic device and an expansion assembly. BACKGROUND

[0002] Cameras are widely used in people's daily life. For example, cameras can be applied in roads, parks, indoor environments, etc. to realize image acquisition and other functions. With the development of technology and the continuous improvement of people's needs, users hope that cameras can have more functions. For example, some users hope that cameras can have wireless communication functions; some users hope that cameras can have face recognition, license plate recognition, etc. To meet the different needs of different customers, the required functional circuits (such as communication circuits, processors, etc.) can be added to the camera. However, in actual application, the required functional circuits are usually added to the camera before leaving the factory, and cannot be added after leaving the factory or in the application site, which may result in incomplete or redundant functions of the camera. SUMMARY

[0003] The present application provides an electronic device and an expansion assembly which can be flexibly expanded and installed.

[0004] In one aspect, the present application provides an electronic device, which includes a main device assembly and an expansion assembly. The main device assembly includes a first housing and a main circuit. The first housing has a first accommodating cavity, and the main circuit is arranged in the first accommodating cavity. The expansion assembly includes a second housing and an expansion circuit. The second housing has a second accommodating cavity, and the expansion circuit is arranged in the second accommodating cavity. The expansion circuit is signal connected with the main circuit to expand or improve the functionality of the main device assembly. In order to realize the quick installation and disassembly between the expansion assembly and the main device assembly, the first housing has a first mounting structure, and the second housing has a second mounting structure. The first mounting structure is detachably connected with the second mounting structure to realize the detachable connection between the expansion assembly and the main device assembly.

[0005] In specific implementation, the types and quantities of the expansion circuit included in the expansion assembly can be various. For example, the expansion circuit can be a radar, a WiFi module, a 4G communication module, a 5G communication module, a Bluetooth module, etc. It can also be a graphics processor, an Ai processing chip, a memory, etc.

[0006] In actual application, the required expansion circuit can be added to the expansion assembly before leaving the factory, or can be added to the expansion assembly in the engineering site, which has great flexibility and will not cause incomplete or redundant functions, etc. In addition, when the expansion circuit is added, the main device assembly does not need to be disassembled, so as not to affect the air tightness of the main device assembly itself.

[0007] In a specific configuration, the first mounting structure can include a slot arranged along the first direction; and the second mounting structure can include a tongue arranged along the first direction. Specifically, the tongue can be inserted into the slot along the first direction, so as to realize the fixed connection between the first shell and the second shell. When assembling the expansion assembly and the main device assembly, the tongue and the slot can be inserted and matched with each other, so as to realize the quick mounting and dismounting between the expansion assembly and the main device assembly, and the mounting and dismounting steps are simple, thereby facilitating the convenience and efficiency during the mounting and dismounting.

[0008] In an implementation manner, in order to improve the connection stability between the expansion assembly and the main device assembly, other connection structures can also be used to realize the detachable connection between the two.

[0009] For example, the first shell can be provided with a first connecting hole, and the second shell can be provided with a second connecting hole, and the first connecting hole and the second connecting hole can be connected through a fastener.

[0010] In a specific configuration, the first connecting hole can be a threaded hole, the second connecting hole can be a through hole, and the fastener can be a bolt. During the mounting, the fastener can be inserted from one end of the second connecting hole, and then the fastener is screwed with the first connecting hole, so as to realize the detachable connection between the first connecting hole and the second connecting hole.

[0011] In addition, in other embodiments, the specific types of the first connecting hole, the second connecting hole and the fastener can be adaptively adjusted according to actual needs. For example, the first connecting hole and the second connecting hole can also be pin holes, and correspondingly, the fastener can be a pin.

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

[0013] Specifically, the tongue and the slot are arranged along a first direction, and the first connecting hole and the second connecting hole are arranged along a second direction. After the tongue is inserted into the slot, the first shell and the second shell can be positionally limited in the second direction, preventing the second shell from being positionally offset relative to the first shell in the second direction. After the fastener is fixedly connected to the first connecting hole and the second connecting hole, the first shell and the second shell can be positionally limited in the first direction, effectively preventing the second shell from being positionally offset relative to the first shell in the first direction, thereby effectively improving the relative stability between the first shell and the second shell and preventing positional offset therebetween. In addition, since the tongue and the slot can positionally limit the first shell and the second shell in the second direction, the fastener can be prevented from being loosened and other adverse problems from occurring between the first connecting hole and the second connecting hole.

[0014] In a specific configuration, an included angle between the first direction and the second direction can be reasonably set according to different situations. Specifically, the included angle between the first direction and the second direction can be between 0° and 90°.

[0015] In addition, in order to facilitate signal connection between the host device assembly and the expansion assembly, the host device assembly can further include a first connector, and the expansion assembly can further include a second connector. When the expansion assembly is assembled with the host device assembly, the signal connection between the host device assembly and the expansion assembly can be achieved through the docking of the first connector and the second connector.

[0016] In a specific configuration, the first connector and the second connector can be connected in the second direction, so as to improve the installation convenience and reliability between the host device assembly and the expansion assembly. The first shell includes a shell body and a support.

[0017] In some implementations, the first shell can include a shell body and a support, and the shell body and the support are detachably connected.

[0018] In a specific configuration, the first accommodating cavity can be arranged in the shell body, and the first mounting structure can be arranged on the shell body or the support.

[0019] On the other hand, the application also provides an expansion assembly configured with a shielding cover assembly. The shielding cover assembly can be arranged on the top and side of the second shell to shield the second shell, preventing the second shell from being exposed to the sun, rain, sand, and the like.

[0020] In a specific configuration, the shielding cover assembly can include a shielding cover body for covering the second housing. The shielding cover body and the second housing can be fixedly connected in a clamping manner. The second housing can be provided with a clamping hook, and the shielding cover body can be provided with a clamping groove. The clamping hook and the clamping groove can be clamped and matched to quickly connect the shielding cover body and the second housing.

[0021] To facilitate the removal of the shielding cover body from the second housing, the shielding cover assembly can further include a button. The user can press the button to separate the clamping hook from the clamping groove, so as to separate the shielding cover body from the second housing. In a specific configuration, the button can include a pressing portion for manual operation and a pushing portion for pushing the clamping hook. When the shielding cover assembly is removed from the second housing, the pressing portion of the button is pressed by the hand, and the pushing portion of the button pushes the clamping hook to make the clamping hook elastically deform and separate from the clamping groove, thereby facilitating the removal of the shielding cover assembly from the second housing.

[0022] In addition, when the button is pressed, in order to ensure that the button is on the correct moving path, the button can be provided with a positioning column, and the shielding cover body can be provided with a sliding hole. The positioning column is slidably arranged in the sliding hole. When the hand exerts pressure on the button, the button can slide along the length direction of the positioning column (or the sliding hole), thereby effectively improving the use effect of the button.

[0023] In addition, when the button is pressed, in order to ensure that the button is on the correct moving path, the button can be provided with a positioning column, and the shielding cover body can be provided with a sliding hole. The positioning column is slidably arranged in the sliding hole. When the hand exerts pressure on the button, the button can slide along the length direction of the positioning column (or the sliding hole), thereby effectively improving the use effect of the button.

[0024] In addition, the application also provides an expansion assembly capable of adjusting the direction of the expansion circuit. The expansion assembly includes a rotating assembly. The expansion circuit is connected with the second housing through the rotating assembly. The rotating assembly is used to drive the expansion circuit to rotate, so as to change the orientation or position of the expansion circuit.

[0025] In a specific configuration, the rotating assembly can include a motor. The stator of the motor is fixed on the second housing, and the rotor is fixedly connected with the expansion circuit. When the rotor rotates, the orientation of the expansion circuit can be changed, thereby improving the use performance of the expansion circuit.

[0026] On the other hand, the application also provides an expansion assembly for detachable connection with a main device assembly. The expansion assembly includes an expansion circuit and a housing. The expansion circuit is electrically connected with the main circuit in the main device assembly.

[0027] In an implementation, the extension assembly can be equipped with a shielding cover assembly. The shielding cover assembly can cover the top and side of the shell to shield the shell from the sun, rain, sand and dust.

[0028] In a specific configuration, the shielding cover assembly can include a shielding cover body for covering the periphery of the shell. The shielding cover body and the shell can be fixedly connected in a clamping manner. The shell can be provided with a clamping hook, and the shielding cover body can be provided with a clamping groove. The clamping hook and the clamping groove can be clamped and matched to quickly connect the shielding cover body and the shell.

[0029] To facilitate the removal of the shielding cover body from the shell, the shielding cover assembly can further include a button. The user can press the button to separate the clamping hook from the clamping groove to facilitate the separation of the shielding cover body and the shell. In a specific configuration, the button can include a pressing portion for manual operation and a pushing portion for pushing the clamping hook. When the shielding cover assembly is removed from the shell, the user presses the button by acting on the pressing portion of the button. The pushing portion of the button pushes the clamping hook to elastically deform and separate from the clamping groove, thereby facilitating the removal of the shielding cover assembly from the shell.

[0030] In addition, when the button is pressed, in order to ensure that the button is on the correct moving path, the button can be provided with a positioning column, and the shielding cover body can be provided with a sliding hole. The positioning column is slidably arranged in the sliding hole. When the user applies pressure to the button, the button can slide along the length direction of the positioning column (or the sliding hole), thereby effectively improving the use effect of the button.

[0031] In addition, when the button is pressed, in order to ensure that the button is on the correct moving path, the button can be provided with a positioning column, and the shielding cover body can be provided with a sliding hole. The positioning column is slidably arranged in the sliding hole. When the user applies pressure to the button, the button can slide along the length direction of the positioning column (or the sliding hole), thereby effectively improving the use effect of the button.

[0032] In addition, the application also provides an extension assembly capable of adjusting the direction of the extension circuit. The extension assembly includes a rotating assembly. The extension circuit is connected with the shell through the rotating assembly. The rotating assembly is used to drive the extension circuit to rotate to change the orientation or position of the extension circuit.

[0033] In a specific configuration, the rotating assembly can include a motor. The stator of the motor is fixed on the shell, and the rotor is fixedly connected with the extension circuit. When the rotor rotates, the orientation of the extension circuit can be changed, thereby improving the use performance of the extension circuit.

[0034] In a specific application, the main device assembly can be a camera, an outdoor base station (such as a base station for transmitting and receiving wireless signals), etc. The type of the main device assembly is not limited in the application. BRIEF DESCRIPTION OF DRAWINGS

[0052] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings.

[0053] In order to facilitate the understanding of the expansion assembly provided by the embodiments of the present application, the application scenario thereof will be introduced first below.

[0054] The expansion assembly provided by the present application can be applied in main device assemblies such as video cameras and outdoor base stations, so as to expand and improve the functionality of the corresponding main device assemblies. Taking a video camera as an example, the video camera generally comprises a lens assembly, which is used to realize the image information acquisition function. At present, in order to enable the video camera to have certain information processing capability (such as face recognition, license plate recognition, etc.), some manufacturers usually increase an additional processor inside the video camera. However, in order to ensure the air tightness of the lens assembly, the installation work of the processor can only be performed before the video camera is shipped, and thus cannot be reasonably adjusted in the engineering site. In addition, in order to enable the video camera to have wireless communication function, some manufacturers usually increase a wireless communication circuit on the video camera. However, in actual application, in order to meet the heat dissipation requirement of the video camera itself, the video camera usually adopts a metal shell such as aluminum alloy, and thus in order to prevent the signal of the wireless communication circuit from being shielded by the metal shell, the wireless communication circuit can only be installed on the shell of the video camera, and cannot be installed inside the video camera. When the wireless communication circuit is installed on the shell, it will occupy part of the area of the shell, and thus will reduce the heat dissipation of the video camera. In addition, in actual application, the wireless communication circuit needs to be connected with the camera body through a cable, and the position where the cable is connected with the camera body needs to be sealed to ensure the air tightness of the lens assembly. On the other hand, after the sealing work is completed, the lens assembly also needs to be tested for air tightness, and thus the installation work of the wireless communication circuit can only be performed before the shipment, and cannot be performed in the engineering site (or after the video camera is shipped), thereby existing great limitation.

[0055] In practical applications, due to different application scenarios of the camera and different functional requirements of different users, the types and quantities of the functional circuit added to the camera are also different. However, due to the air tightness requirement of the lens assembly (or the camera itself), the functional circuit added to the camera can only be configured before leaving the factory, which may cause incomplete functions or redundant functions in practical applications. It can be understood that the camera described above includes but is not limited to a spherical camera, a semi-spherical camera, a cylindrical camera, and the like, and the above is only a simple description taking the camera as an example. However, in practical applications, the main device assembly such as an outdoor base station (e.g., a base station for transmitting and receiving wireless signals) also faces the same or similar technical problems as the camera when adding a functional circuit.

[0056] Therefore, an embodiment of the present application provides an expansion assembly capable of flexible and rapid installation and an electronic device equipped with the expansion assembly.

[0057] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0058] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms “a,” “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “at least one,” “one or more,” as used in the following embodiments, mean one, two, or more than two. The term “and / or” is used to describe the association relationship of the associated objects, which means that there can be three relationships; for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character “ / ” generally represents an “or” relationship between the associated objects.

[0059] In the present specification, the reference to “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in one or more embodiments of the present application. Therefore, the statements “in one embodiment,” “in some embodiments,” “in other some embodiments,” “in yet some embodiments,” and the like appearing in various places in the specification are not necessarily all referring to the same embodiment, but mean “one or more but not all embodiments,” unless otherwise specifically stated. The terms “include,” “contain,” “have” and their variants mean “including but not limited to,” unless otherwise specifically stated.

[0060] As Figure 1 shown, the embodiment provided by the present application provides an electronic device, which comprises a main device assembly 10 and an expansion assembly 20; the main device assembly 10 comprises a first shell 11 and a main body circuit 12, the first shell 11 has a first accommodating cavity 1111, and the main body circuit 12 is arranged in the first accommodating cavity 1111. The expansion assembly 20 comprises a second shell 21 and an expansion circuit 22. The second shell 21 has a second accommodating cavity 211, the expansion circuit 22 is arranged in the second accommodating cavity 211, and the expansion circuit 22 is signal connected with the main body circuit 12 to expand or improve the functionality of the main device assembly 10. In order to realize the quick installation and disassembly between the expansion assembly 20 and the main device assembly 10, the first shell 11 has a first mounting structure (not marked in the figure), the second shell 21 has a second mounting structure (not marked in the figure), and the first mounting structure and the second mounting structure are detachably connected to realize the detachable connection between the expansion assembly 20 and the main device assembly 10.

[0061] In specific implementation, the types and quantities of the expansion circuit 22 contained in the expansion assembly 20 can be various. For example, the expansion circuit 22 can be: a radar, a WiFi module, a 4G communication module, a 5G communication module, a Bluetooth module and the like communication circuit. It can also be: a graphic processor, an Ai processing chip, a memory and the like device. In actual application, the required expansion circuit 22 can be added in the expansion assembly 20 before leaving the factory, or the required expansion circuit 22 can be added in the expansion assembly 20 in the engineering site, so that greater flexibility is achieved, and adverse problems such as incomplete function or function redundancy will not occur. In addition, when the expansion circuit 22 is added, the main device assembly 10 does not need to be disassembled, so that the air tightness and the like of the main device assembly 10 itself will not be affected.

[0062] In specific implementation, the specific structural configuration of the expansion assembly 20 and the main device assembly 10 can be various.

[0063] For example, as Figure 1 shown, in the embodiment provided by the present application, the first shell 11 comprises a shell body 111 and a support 112; wherein the second accommodating cavity 1111 is located in the shell body 111; the support 112 is used for fixing the shell body 111 at a mounting position (such as a wall, a road monitoring rod and the like), and the support 112 can also be detachably connected with the second shell 21. That is, the shell body 111 and the second shell 21 are detachably connected through the support 112. It can be understood that in other embodiments, the second shell 21 can also be directly fixedly connected with the shell body 111.

[0064] In practical applications, when it is necessary to expand or enhance the functionality of the main device component 10, the required expansion component 20 can be installed on the main device component 10 through the first mounting structure and the second mounting structure.

[0065] like Figure 2 As shown, in one embodiment provided in this application, the first mounting structure includes a slot 1121 disposed along a first direction; the second mounting structure includes a tongue 212 disposed along the first direction. Specifically, the tongue 212 can be inserted into the slot 1121 along the first direction, thereby realizing a fixed connection between the bracket 112 and the second housing 21. When assembling the expansion component 20 with the main device component 10, the mutual insertion and cooperation of the tongue 212 and the slot 1121 can realize quick installation and disassembly between the expansion component 20 and the main device component 10, and the disassembly and assembly steps are simple, thereby improving the convenience and efficiency of disassembly and assembly.

[0066] In practical implementation, the shapes and contours of the tongue 212 and the slot 1121 can be approximately the same, thereby improving the relative stability between them. For example, when the tongue 212 is a rectangular plate structure, the slot 1121 can also be a rectangular groove structure. After the tongue 212 is inserted into the slot 1121, the side of the tongue 212 can abut against or maintain a small gap with the inner wall of the slot 1121 to prevent significant shaking or other adverse situations from occurring within the slot 1121. It is understood that in other embodiments, the tongue 212 can also be a plate structure with a semi-circular, triangular, or other similar shapes. Correspondingly, the slot 1121 can also be a groove structure with a semi-circular, triangular, or other similar shapes.

[0067] In some embodiments, the tongue 212 and the slot 1121 can also be assembled by an interference fit. For example, the size of the tongue 212 can 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 can be formed between the tongue 212 and the inner wall of the slot 1121 to prevent loosening or other defects.

[0068] During manufacturing, the tongue 212 and the second housing 21 can be either two independent structural components or an integral structural component. Specifically, when the tongue 212 and the second housing 21 are two independent structural components, the tongue 212 and the second housing 21 can be manufactured separately, and then the tongue 212 can be installed on the second housing 21 using fasteners such as welding or screws. When the tongue 212 and the second housing 21 are an integral structural component, the tongue structure can be directly molded onto the second housing 21 using methods such as injection molding.

[0069] It can be understood that in the above embodiment, the tongue 212 is arranged on the second shell 21, and the slot 1121 is arranged on the support 112. In other embodiments, the positions of the tongue 212 and the slot 1121 can also be interchanged. That is, the tongue 212 can be arranged on the support 112, and the slot 1121 can be arranged on the second shell 21.

[0070] In addition, in a specific arrangement, the number of tongues 212 is two or more, and accordingly, the number of slots 1121 can also be adjusted adaptively according to the number of tongues 212, which is not limited in the present application.

[0071] In a specific configuration, in order to improve the connection stability between the expansion assembly 20 and the main device assembly 10, other connection structures can also be used to achieve detachable connection between the two.

[0072] For example, as shown in FIG. 1, in an embodiment provided by the present application, the support 112 is provided with a first connecting hole 1122, and the second shell 21 is provided with a second connecting hole 213. The first connecting hole 1122 and the second connecting hole 213 are connected by a fastener 30. Figure 3

[0073] In a specific arrangement, the first connecting hole 1122 can be a threaded hole, the second connecting hole 213 can be a through hole, and the fastener 30 can be a bolt. In installation, the fastener 30 can be inserted from the upper end of the second connecting hole 213, and then the fastener 30 is screwed with the first connecting hole 1122, so as to achieve detachable connection between the first connecting hole 1122 and the second connecting hole 213.

[0074] Please refer to Figure 2 and Figure 3 In installation, the tongue 212 can be inserted into the slot 1121 first, so as to achieve relative fixation between the support 112 and the second shell 21. Then, the fastener 30 is inserted into the first connecting hole 1122 and the second connecting hole 213, so as to achieve fixed connection between the first connecting hole 1122 and the second connecting hole 213, thereby achieving fixed connection between the support 112 and the second shell 21.

[0075] In a specific configuration, in order to improve the connection effect between the support 112 and the second shell 21, the setting direction of the tongue 212 (or the slot 1121) can be arranged at an angle with the setting direction of the first connecting hole 1122 (or the second connecting hole 213).

[0076] ​For example, in the embodiments provided in this application, the tongue 212 and the slot 1121 are both arranged along a first direction, and the first connecting hole 1122 and the second connecting hole 213 are both arranged along a second direction, with the first direction and the second direction being perpendicular to each other. When the tongue 212 is inserted into the slot 1121, it can limit the position of the second housing 21 and the bracket 112 in the second direction, preventing the second housing 21 from shifting relative to the bracket 112 in the second direction. When the fastener 30 is fixedly connected to the first connecting hole 1122 and the second connecting hole 213, it can limit the position of the second housing 21 and the bracket 112 in the first direction, thereby effectively preventing the second housing 21 from shifting relative to the bracket 112 in the first direction, thus effectively improving the relative stability between the second housing 21 and the bracket 112 and preventing positional shift between them. In addition, since the cooperation between the tongue 212 and the slot 1121 can limit the position of the second housing 21 and the bracket 112 in the second direction, it can prevent problems such as loosening between the fastener 30 and the first connecting hole 1122 and the second connecting hole 213 to a certain extent.

[0077] In specific configurations, the angle between the first direction and the second direction can be set appropriately according to different situations. Specifically, the angle between the first direction and the second direction can be between 0° and 90°.

[0078] It is understood that in other embodiments, the first connecting hole 1122 can be a through hole structure, and the second connecting hole 213 can be a threaded hole. During installation, the fastener 30 can be inserted through one end of the first connecting hole 1122, and then the fastener 30 can be screwed into the second connecting hole 213, thereby achieving a detachable connection between the first connecting hole 1122 and the second connecting hole 213.

[0079] In other embodiments, the specific types of the first connecting hole 1122, the second connecting hole 213, and the fastener 30 can be adapted to actual needs. For example, the first connecting hole 1122 and the second connecting hole 213 can also be pin holes, and correspondingly, the fastener 30 can be a pin, etc.

[0080] In addition, such as Figure 4 As shown, to facilitate signal connection between the main device component 10 and the expansion component 20, the main device component 10 may further include a first connector 1123, and the expansion component 20 may further include a second connector 214. When the expansion component 20 is assembled with the main device component 10, signal connection between the main device component 10 and the expansion component 20 can be achieved by mating the first connector 1123 and the second connector 214.

[0081] Specifically, in one embodiment provided in the present application, the first connector 1123 is arranged on the bracket 112, and the lower end of the first connector 1123 is electrically connected with the main body circuit 12. The second connector 214 is arranged on the second shell 21, and the upper end of the second connector 214 is electrically connected with the expansion circuit 22. When the first connector 1123 and the second connector 214 are docked, the signal connection between the main body circuit 12 and the expansion circuit 22 can be realized.

[0082] In a specific configuration, the first connector 1123 and the second connector 214 can be plugged in the second direction. When the expansion assembly 20 is installed on the main device assembly 10, the fixed connection between the expansion assembly 20 and the main device assembly 10 and the docking between the first connector 1123 and the second connector 214 can be realized at the same time.

[0083] Please refer to Figures 4 to 6 When installing, the relative inclined posture between the expansion assembly 20 and the main device assembly 10 can be maintained, so that the tongue 212 is inserted into 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 at the same time, the first connector 1123 and the second connector 214 are gradually docked. When the tongue 212 is completely inserted into the slot 1121, the first connector 1123 and the second connector 214 are docked, and at the same time, the first connecting hole 1122 and the second connecting hole 213 are 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 main device assembly 10 is realized.

[0084] In the above embodiment, the tongue 212 and the slot 1121 are plugged and matched, and the first connecting hole 1122 and the second connecting hole 213 are matched, so that the rapid installation between the expansion assembly 20 and the main device assembly 10 can be realized; at the same time, during the assembly process, the docking between the first connector 1123 and the second connector 214 can be realized, so that the signal between the expansion assembly 20 and the main device assembly 10 can be realized. The installation steps are simple, which is beneficial to improve the convenience and efficiency during assembly.

[0085] In some embodiments, in order to ensure the structural safety of the tongue 212 and prevent the tongue 212 from being broken or other adverse conditions, the tongue 212 can have a certain elasticity. When the expansion assembly 20 and the main device assembly 10 are assembled in a relative inclined posture, the tongue 212 can better match the slot 1121 through its own elastic deformation, so that the installation effect and the structural safety can be effectively improved.

[0086] In a specific arrangement, the connection between the housing body 111 and the support 112 can be various.

[0087] As shown in the embodiments provided in the present application, the housing body 111 is arranged on the support 112 in a rotatable manner; that is, the housing body 111 can rotate relative to the support 112; the lens assembly 110 is installed in the housing body 111, and by adjusting the rotation angle of the housing body 111, the orientation of the lens assembly 110 can be adjusted to change and improve the image acquisition range of the lens assembly 110. Figure 7

[0088] Specifically, the housing body 111 includes a base 1112 and a connecting disc 1113, and the base 1112 and the connecting disc 1113 are fixedly connected by screws 31.

[0089] The connecting disc 1113 is provided with three through holes (not shown in the figure), and the side (the upper side in the figure) of the base 1112 facing the connecting disc 1113 is provided with three threaded holes (not shown in the figure), and the three through holes and the three threaded holes are arranged one by one. After three screws 31 are respectively inserted and fixed in the corresponding through holes and threaded holes, the fixed connection between the connecting disc 1113 and the base 1112 can be achieved.

[0090] It can be understood that in other embodiments, the number and position of the through holes and threaded holes can be adjusted adaptively according to different needs. Alternatively, the connecting disc 1113 and the base 1112 can also be fixedly connected by clamping, welding or the like, which is not limited in the present application.

[0091] In order to realize the rotatable adjustment between the housing body 111 and the support 112.

[0092] As shown in the embodiments provided in the present application, the housing body 111 is arranged on the support 112 in a rotatable manner; that is, the housing body 111 can rotate relative to the support 112; the lens assembly 110 is installed in the housing body 111, and by adjusting the rotation angle of the housing body 111, the orientation of the lens assembly 110 can be adjusted to change and improve the image acquisition range of the lens assembly 110. Figure 8

[0093] ​​The bottom of the support 112 is provided with a first friction surface 1126 arranged downwardly, the connecting disc 1113 is provided with a second friction surface 11132 arranged upwardly, and the friction ring 13 is arranged between the first friction surface 1126 and the second friction surface 11132. When the upper surface of the friction ring 13 is in contact with the first friction surface 1126 and the lower surface of the friction ring 13 is in contact with the second friction surface 11132, the connecting disc 1113 can be prevented from rotating relative to the support 112 under the action of friction. When the first friction surface 1126 is not in contact with the friction ring or the second friction surface 11132 is not in contact with the friction ring 13, the connecting disc 1113 can be manually rotated to rotate the connecting disc 1113 relative to the support 112.

[0094] In addition, in order to make the first friction surface 1126 and the friction ring 13 maintain the contact state and the second friction surface 11132 and the friction ring 13 maintain the contact state in the normal state, in the embodiments provided in the present application, a compression spring 14 is further arranged between the support 112 and the connecting disc 1113.

[0095] Please refer to Figure 8 and Figure 9 . Specifically, the inner wall of the through hole 1124 has a flange 1125 extending inwardly, the top of the convex shaft 11131 is provided with a stop ring 11133, the compression spring 1414 is sleeved on the outer periphery of the convex shaft 11131, and the upper end of the compression spring 14 abuts against the lower side of the stop ring 11133, and the lower end of the compression spring 14 abuts against the flange 1125. That is, the compression spring 14 is arranged between the connecting disc 1113 and the support 112, and is used for applying an upward elastic force to the stop ring 11133. Since the stop ring 11133 is fixedly connected with the connecting disc 1113, the compression spring 14 can apply an upward elastic force to the connecting disc 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 maintain the contact state and the second friction surface 11132 and the friction ring 13 maintain the contact state. When it is necessary to adjust the rotation angle of the connecting disc 1113 (or the shell body 111), the hand of a person acts on the connecting disc 1113 (or the shell body 111) and lifts upwardly, so that the first friction surface 1126 and the friction ring 13 are in a non-contact state and the second friction surface 11132 and the friction ring 13 are in a non-contact state. The connecting disc 1113 (or the shell body 111) can be easily rotated, so that the rotation angle of the connecting disc 1113 (or the shell body 111) can be adjusted.

[0096] In a specific configuration, the friction ring 13 can be made of a ring structure of silica gel, foam or other materials, so that the friction ring 13 has a large friction coefficient between the first friction surface 1126 and the second friction surface 11132. In addition, the friction ring 13 can also have a certain damping effect, which can effectively reduce the transmission of vibration between the connecting disc 1113 and the support 112.

[0097] During installation, the friction ring 13 can be sleeved on the outer periphery of the convex shaft 11131, then the convex shaft 11131 is arranged in the through hole, and the compression spring 14 is sleeved on the outer periphery of the convex shaft 11131. Finally, the stop ring 11133 is fixed on the top of the convex shaft 11131 by the screw 32, realizing the fixed connection between the stop ring 11133 and the convex shaft 11131, and the compression spring 14 is compressed between the stop ring 11133 and the flange 1125.

[0098] It can be understood that in other embodiments, the first friction surface 1126 and the second friction surface 11132 can also be roughened to increase the friction between the first friction surface 1126 and the friction ring 13, and the friction between the second friction surface 11132 and the friction ring 13. In a specific configuration, the friction ring 13 can be provided in a ring structure, or in a sheet, block or other structure. The specific shape and material of the friction ring 13 are not limited in the present application. Alternatively, in another embodiment, the friction ring 13 can be omitted, and the first friction surface 1126 and the second friction surface 11132 can be directly contacted. Alternatively, a tooth structure can be provided on the first friction surface 1126 and the second friction surface 11132 to improve the locking effect between the connecting disc 1113 and the support 112.

[0099] In a specific configuration, the shape of the expansion assembly 10 can also be various.

[0100] As shown in Figure 10 and Figure 11 In one embodiment provided by the present application, the second shell 21 includes an inner shell 215 and an outer shell 216, and the outer shell 216 is sleeved on the outer periphery of the inner shell 215, so that the inner shell 215 and the outer shell 216 form a second accommodating cavity 211 for installing the expansion circuit 22.

[0101] Specifically, the inner shell 215 is configured as a hollow structure, and the cross section of the inner contour is circular and the cross section of the outer contour is quadrangular. The space surrounded by the inner contour forms an upper and lower through heat dissipation air duct 217. The expansion circuit 22 can be fixedly connected with the quadrangular side surface of the inner shell 215, and the heat generating elements in the expansion circuit 22 can be in thermal connection with the inner shell 215 through a heat conductive silica gel or other medium, so that the heat generated by the heat generating elements can be effectively transmitted to the inner shell 215 for heat dissipation.

[0102] In a specific implementation, multiple extension circuits 22 can be provided, and multiple extension circuits 22 can be arranged on different surfaces of the inner shell 215. For example, when four extension circuits 22 are provided, the four extension circuits 22 can be arranged on four sides of the inner shell 215. It can be understood that in other implementations, the number and arrangement of the extension circuits 22 can be adjusted as needed. In addition, the shape of the inner shell 215 can also be other shapes. For example, the inner profile of the inner shell 215 can be circular, oval, square, or other polygonal structures. The outer profile can be circular, oval, square, or other polygonal structures. In addition, the shape of the inner profile and the outer profile of the inner shell 215 can be the same or different. For example, the inner profile and the outer profile of the inner shell 215 can both be circular. Alternatively, the inner profile of the inner shell 215 can be circular, and the outer profile can be square.

[0103] In another aspect, the embodiments of the present application also provide an extension assembly 20 capable of adjusting the direction of the extension circuit 22.

[0104] As shown in Figure 12 and Figure 13 In an embodiment provided by the present application, the outer shell 216 is arranged on the upper side of the inner shell 215 to form a second accommodating space 211. The extension assembly 20 further comprises a rotating assembly (not shown in the figure), and the extension circuit 22 is fixed in the second accommodating space 211 by the rotating assembly.

[0105] Specifically, the rotating assembly comprises a motor 218. The stator of the motor 218 is fixed on the inner shell 215, and the rotor is fixedly connected with the extension circuit 22. When the rotor rotates, the orientation of the extension circuit 22 can be changed, thereby improving the use performance of the extension circuit 22. For example, when the extension circuit 22 comprises a WiFi module, a radio frequency module, etc., the orientation of the WiFi module and the radio frequency module can be adjusted to adjust the emission direction of the electromagnetic wave, thereby effectively improving the use performance.

[0106] In a specific configuration, the rotation direction of the extension circuit 22 can be set according to different needs. For example, in an embodiment provided by the present application, the motor 218 is arranged vertically to enable the extension circuit 22 to rotate around the rotation center of the motor. It can be understood that in a specific configuration, the motor 218 can also be arranged obliquely or horizontally.

[0107] In addition, in other implementations, the output shaft of the motor 218 and the extension circuit 22 can also be connected by a transmission mechanism such as a belt, a gear, a chain, etc., to enable the motor 218 to drive the extension circuit 22 to rotate.

[0108] On the other hand, embodiments of this application also provide an extension component 20 configured with a masking assembly 23.

[0109] Specifically, such as Figure 14 As shown in the embodiments provided in this application, the shielding assembly 23 can be installed on the top and sides of the second housing 21 to provide good shielding for the second housing 21 and prevent the second housing 21 from being exposed to the sun, rain, sand and dust.

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

[0111] In practice, the connection between the top cover 232 and the shielding body 231 can be varied.

[0112] For example, such as Figure 15 and Figure 16 As shown in the embodiment provided in this application, the upper cover 232 and the shielding body 231 are fixedly connected by a snap-fit ​​method. The upper cover 232 has a downwardly extending hook 2321 on its bottom side, and the shielding body 231 has a slot 2311 on its upper side. During assembly, the upper cover 232 can be placed on the upper side of the shielding body 231, and the upper cover 232 can be pressed downwards to engage the hook 2321 with the slot 2311, thus achieving assembly between the upper cover 232 and the shielding body 231.

[0113] It is understood that in other embodiments, the upper cover 232 and the shielding body 231 can also be fixedly connected by means of bonding, threaded connection, welding, etc. Alternatively, in some other embodiments, the upper cover 232 and the shielding body 231 can also be an integral structure. For example, the upper cover 232 and the shielding body 231 can be directly molded into an integral structure using an injection molding process.

[0114] In addition, in specific implementations, the connection method between the shield body 231 and the second housing 21 can also be various.

[0115] For example, such as Figure 15 and Figure 17 As shown, in one embodiment provided in this application, the shielding body 231 and the second housing 21 are also fixedly connected by a snap-fit ​​method. The top of the second housing 21 has an upwardly extending hook 219, and the lower side of the shielding body 231 has a slot 2312. The hook 219 and the slot 2312 engage to achieve a quick connection between the shielding body 231 and the second housing 21.

[0116] When the shielding cover body 231 is installed on the second shell 21, the shielding cover body 231 can be covered on the second shell 21, and then the shielding cover body 231 is pressed downward, so that the clamping hooks 219 are clamped with the clamping grooves 2312, and the connection between the shielding cover body 231 and the second shell 21 can be realized.

[0117] In order to facilitate the shielding cover body 231 to be taken off from the second shell 21.

[0118] As shown in Figure 15 and Figure 17 In the embodiments provided in the present application, the shielding cover assembly 23 further comprises a button 233. The user can separate the clamping hooks 219 from the clamping grooves 2312 by pressing the button 233, so as to separate the shielding cover body 231 from the second shell 21.

[0119] As shown in Figure 15 Specifically, when the shielding cover assembly 23 is taken off from the second shell 21, the hand of a person acts on the pressing part 2331 of the button 233 and presses the button 233 downward.

[0120] As shown in Figure 17 The pushing part 2332 of the button pushes the clamping hooks 219, so that the clamping hooks 219 are elastically deformed to the right and separated from the clamping grooves 2312. While the button 233 is pressed, the shielding cover body 231 is pulled upward, so that the shielding cover assembly 23 can be taken off from the second shell 21. In the embodiments provided in the present application, the pushing part 2332 is configured as a trapezoidal protruding structure. It can be understood that in other embodiments, the pushing part 2332 can also be configured as a triangular protrusion or other structure, which is not limited in the present application.

[0121] As shown in Figure 16 In order to ensure that the button 233 is on the correct moving path when the button 233 is pressed, in the embodiments provided in the present application, the bottom of the button 233 is further provided with a positioning column 2333, and the shielding cover body 231 is provided with a sliding hole 2313, and the positioning column 2333 is slidably arranged in the sliding hole 2313. When the hand of a person applies pressure to the button 233, the button 233 can slide along the length direction of the positioning column 2333 (or the sliding hole 2313), so as to effectively improve the use effect of the button 233.

[0122] In addition, in order to enable the button 233 to automatically return to the position when it is not pressed, in the embodiments provided in the present application, the shielding cover assembly 23 further comprises a reset spring 234.

[0123] Specifically, the reset spring 234 is sleeved on the outer periphery of the positioning column 2333, the upper end of which abuts against the bottom surface of the button 233, and the lower end of which abuts against the shielding cover body 231. When the button 233 is pressed downward under the action of an external force, the reset spring 234 is compressed and deformed; after the external force is eliminated, the reset spring 234 tends to elongate and push the button 233 to move upward, so that the button 233 is reset to the position before being pressed.

[0124] It can be understood that, in specific configurations, the reset spring 234 can be in the form of a spiral spring, a spring sheet or the like, which is not specifically limited in the present application.

[0125] In addition, the number and arrangement position of the positioning column 2333 and the sliding hole 2313 can be adaptively adjusted according to different requirements.

[0126] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
