[0071] The present application provides a camera.

[0072] In this embodiment, the camera includes: a barrel shell 10, a first circuit board 61, a cable 90, a wireless communication component 30 and a cover 20.

[0073] The barrel shell 10 is a metal part, and a accommodating cavity is formed in the barrel shell 10. A cable hole 121 is provided at the tail end 12 of the barrel shell 10, and an opening 11 is provided on the circumferential side wall of the barrel shell 10. The cable hole 121 and the opening 11 are both connected to the accommodating cavity, and the opening 11 is arranged close to the cable hole 121; the first circuit board 61 is arranged in the accommodating cavity, and the extension direction of the first circuit board 61 is parallel to the axial direction of the barrel shell 10, and one side wall surface of the first circuit board 61 is arranged opposite to the opening 11, so that at least one cable docking socket 611 on the side wall surface is exposed from the opening 11; one end of the cable 90 is connected to the cable docking socket 611, and the other end is passed through the barrel shell 10 from the cable hole 121; the wireless communication component 30 is arranged at the opening 11 and is spaced apart from the first circuit board 61; the cover 20 is a plastic part, and the cover 20 can be detachably covered on the opening 11.

[0074] Specifically, see Figure 1, since the cylindrical camera is mainly arranged outdoors. There is an accommodation cavity inside the cylindrical body housing 10, and functional modules such as the lens assembly 70 and the circuit board assembly of the cylindrical camera, as well as the cable 90, are accommodated in this accommodation cavity. The cylindrical body housing 10 includes a cylindrical body and a front cover 40. Axially along the cylindrical body, at the front end of the cylindrical body, that is, the open end 13 is opened to form the accommodation cavity, and at the tail end of the cylindrical body, which is also the tail end 12 of the cylindrical body housing, a cable hole 121 communicating with the accommodation cavity is provided. Specifically, the front end of the cylindrical body is opened for internal functional modules such as the lens assembly 70 and the circuit board assembly to extend into the accommodation cavity therefrom. And the front cover 40 covers the open part of the accommodation cavity. The cable hole is for the cable to pass through from the back to the front and enter the accommodation cavity. Among them, the cross-sectional shape of the cylindrical body is a closed polygon. For example, the polygon can be a quadrilateral or an octagon, etc. Thus, the cylindrical body 10 can be obtained by sequentially enclosing 4 or 8 side plates.

[0075] An opening 11 is provided on the upper wall of the cylindrical body housing 10, and the opening 11 communicates with the accommodation cavity. And the opening 11 is arranged close to the cable hole 121, that is, close to the tail end 12.

[0076] The circuit board assembly includes but is not limited to the first circuit board 61, and at least one cable docking socket 611 is provided on the first circuit board 61. The open end 13 has an installation opening 131 communicating with the accommodation cavity. At this time, the front cover 40 is used to cover the installation opening 131. On the side wall of the front cover 40 facing the cylindrical body housing 10, there are arranged the lens assembly 70 and the first circuit board 61. When the front cover 40 covers the installation opening 131, the lens assembly 70 and the first circuit board 61 extend into the accommodation cavity from the installation opening 131. One end of the first circuit board 61 is fixedly connected to the front cover 40, and the other end extends towards the tail end 12. And the length direction of the first circuit board 61 is parallel to the axial direction of the cylindrical body housing 10, and at least part of one side wall surface of the first circuit board 61 faces the opening 11. That is, the first circuit board 61 extends towards the direction close to the tail end 12 to the opening 11. Please refer to Figure 1 and Figure 4 , the cylindrical body housing 10 is horizontally arranged. At this time, the first circuit board 61 can also horizontally extend to the opening 11, that is, adopt a horizontal layout, so that at least one cable docking socket 611 on one side wall surface is exposed from the opening 11. That is, at this time, the cable docking socket 611 is arranged on the upper wall of the first circuit board 61 and at the rear end of the first circuit board 61 corresponding to the opening 11. Compared with the existing vertical arrangement of the first circuit board 61 assembly, which is affected by the cross-section of the cylindrical body and the arrangement area of electronic components is limited. In this embodiment, the first circuit board 61 adopts a horizontal layout, making full use of the internal space of the cylindrical body housing 10, increasing the board area, with a regular shape, and effectively avoiding the situation that the internal cable connection becomes more complex due to the stacking of multiple small boards. At the same time, the area of the first circuit board 61 is larger, which is also convenient for the assembly operation of workers.

[0077] It can be seen that in this embodiment, since the cable docking socket 611 is exposed by the opening 11 and the opening 11 is arranged near the tail end 12, the cable only needs a short length to complete the connection with the cable docking socket 611 after extending from the cable hole at the tail end into the accommodating cavity, and will not touch the electronic components arranged near the open end 13 of the first circuit board 61, thereby avoiding the redundancy of the cable 90 and the poor electromagnetic shielding caused by the overlap of the cable 90 and the electronic components. In addition, the cables are concentrated in the rear space near the barrel shell 10, which is convenient for combing the cables, and can effectively prevent the occurrence of wire pressing, wire clamping and wire winding.

[0078] To ensure the camera's environmental adaptability meets the required requirements, the barrel housing 10 of the cylindrical camera is made of metal. A wireless communication component 30 is located at the opening 11, and the cover 20 covers the opening 11, thereby sealing the barrel housing 10. The wireless communication component 30 is a functional component with wireless transmission capabilities, which can emit electromagnetic waves to the outside world to perform corresponding functions such as communication or distance measurement. It is understood that EMC (Electromagnetic Compatibility) refers to the fact that the electromagnetic interference generated by a device in its environment during operation cannot exceed a certain limit, and the device also has a certain degree of immunity to electromagnetic interference in the environment, namely electromagnetic sensitivity. Therefore, if the wireless communication component 30 is placed in the barrel housing 10 made of metal, the barrel housing 10 will form an electromagnetic shield, which will cause the wireless communication component 30 to malfunction. In this embodiment, however, the cover 20 is made of plastic. Since plastic does not have electromagnetic shielding capabilities, the EMC performance of the wireless communication component 30 is not affected. Therefore, in this embodiment, the placement of the wireless communication component 30 at the opening 11 does not affect the normal operation of the wireless communication component 30.

[0079] Furthermore, the camera provided in this embodiment is compatible with the wireless communication component 30 at the cover 20 , that is, the wireless communication component 30 is located inside the barrel housing 10 . This not only facilitates the expansion and upgrading of the barrel camera's functions, but also protects the wireless communication component 30 from damage due to abnormal factors such as rain and storms, thereby extending its service life. Thus, this embodiment also improves the performance of the wireless communication component 30 after installation.

[0080] Specifically, the shape of the cover member 20 matches the shape of the opening 11, and thus it can be configured as a strip-shaped cover plate, or alternatively, as an arc-shaped plate. The cover member 20 can be fixed or detachably mounted to the opening 11 using snaps, screws, or other equivalent means. In some embodiments, a sealing assembly such as a sealing ring is provided at the opening 11 to enhance the sealing performance of the barrel housing 10, for example, to improve the waterproof and dustproof rating of the barrel camera.

[0081] In a possible embodiment of the present application, the camera further includes: a second circuit board 62, which is stacked with the first circuit board 61. The second circuit board 62 is disposed on the side of the first circuit board 61 away from the opening 11, and a power module is provided on the second circuit board 62. Wherein, the second circuit board 62 is electrically connected to the cable through the first circuit board 61.

[0082] Specifically, due to the limited length of the cylindrical camera, it is difficult for a single first circuit board 61 to install all the electronic components, and there may be other second circuit boards 62 at this time. In order to prevent the second circuit board 62 from affecting the maintenance personnel from disassembling, installing or maintaining the cable 90 connected to the cable docking socket 611 on the first circuit board 61 through the opening 11. At this time, refer to Figure 2 , the second circuit board 62 is stacked with the first circuit board 61 and is disposed on the side of the first circuit board 61 away from the opening 11, that is, the first circuit board 61 and the second circuit board 62 are arranged up and down, wherein the first circuit board 61 is located above.

[0083] Among them, the first circuit board 61 has a cable docking socket 611, so that it can be connected to the cable 90 entering from the tail end 12, and can also be connected to the connection lines of internal functional modules such as the lens assembly 70 on the front cover 40. That is, in this embodiment, all the cable docking sockets 611 that need to be disassembled and installed inside the barrel housing 10 in the camera are integrated on the first circuit board 61 to facilitate later maintenance. And the electronic components such as the power module that can be disassembled and installed outside the barrel housing 10 are integrated on the stacked second circuit board 62 to reduce the length of the first circuit board 61 and improve the utilization rate of the space in the accommodation cavity. Then the second circuit board 62 is electrically connected to the cable 90 through the first circuit board 61.

[0084] In this embodiment, the first circuit board 61 is the main platform of the circuit board assembly, and the second circuit board 62 is the power board of the circuit board assembly.

[0085] As a possible embodiment, in the axial direction of the barrel housing 10, the length dimension of the opening 11 is A, and the length dimension of the barrel housing 10 is B, satisfying: In this embodiment, the length dimension of the opening 11 does not exceed half of the barrel housing 10 at most to avoid affecting the overall strength of the barrel.

[0086] In a possible embodiment of the present application, the orthographic projection of the second circuit board 62 on the first circuit board 61 does not exceed the contour of the first circuit board 61.

[0087] Specifically, please refer to Figure 2, the contour edges of the second circuit board 62 do not exceed those of the first circuit board 61. That is, in order to make full use of the space inside the barrel housing 10 and avoid interference between the electronic components on the second circuit board 62 and the barrel housing 10, the second circuit board 62 is configured as a small board, while the first circuit board 61 is configured as a large board.

[0088] In a possible embodiment of the present application, the camera further includes a lens bracket 41, which is placed in the accommodation cavity and close to the front end of the barrel housing 10; the camera further includes a sheet metal support member 63, which is disposed between the first circuit board 61 and the second circuit board 62. Both the first circuit board 61 and the second circuit board 62 are parallel to the sheet metal support member 63 and are both fixed to the sheet metal support member 63. Wherein, one end of the sheet metal support member 63 is fixedly connected to the lens bracket 41, and the other end of the sheet metal support member 63 extends axially towards the tail end 12 along the barrel housing 10, and one side wall of the sheet metal support member 63 faces the opening, so that the length direction of the first circuit board 61 is parallel to the axial direction of the barrel housing 10 and one side wall surface of the first circuit board 61 faces the opening 11.

[0089] Specifically, please continue to refer to Figure 1 , in this embodiment, the lens bracket 41 is a support structure fixedly connected to the front cover 40, and the lens bracket 41 is close to the front end, that is, close to the lens arrangement, so that there is a space between the lens bracket 41 and the inner wall of the tail end 12 to leave enough installation space for installing the circuit board assembly. Both the first circuit board 61 and the second circuit board 62 in the circuit board assembly are installed and fixed through the sheet metal support member 63. The sheet metal support member 63 can be configured as a plate-like structure, and its structural strength is higher than that of the circuit board. Specifically, the sheet metal support member 63 is disposed between the first circuit board 61 and the second circuit board 62, and one end of the sheet metal support member 63 is fixedly connected to the lens bracket, and the other end of the sheet metal support member 63 extends axially towards the tail end of the barrel housing along the barrel housing. That is, in this embodiment, the sheet metal support member 63 extends horizontally, so that the first circuit board 61 fixed on the upper wall of the sheet metal support member 63 is also horizontally arranged, and the second circuit board 62 arranged on the lower wall of the sheet metal support member 63 can also be horizontally arranged. It can be understood that both the first circuit board 61 and the second circuit board 62 can be fastened to the sheet metal support member 63 by 3 or more screws.

[0090] Since the first circuit board 61 is relatively long, if it is directly arranged in the accommodation cavity in a cantilever beam structure, it is easy to break. Therefore, in this embodiment, the first circuit board 61 is supported by the sheet metal support member 63, so that the first circuit board 61 is more firm.

[0091] In a possible embodiment of the present application, at least part of the end face of the sheet metal support member 63 near the front end is bent and extended to form at least one first fastening portion 64, and the first fastening portion 64 is fixedly connected to the lens bracket 41.

[0092] Specifically, please refer to Figure 1 and Figure 2 , the lens bracket 41 is a columnar structure extending along the axial direction of the barrel housing. At this time, in order to facilitate the fixing of the plate-shaped sheet metal support member 63 on the rear end face of the lens bracket 41, at least a part of the end face of one end of the sheet metal support member 63 close to the front end can be bent vertically upward to form at least one first fastening portion 64. At this time, the first fastening portion 64 and the sheet metal support member 63 are perpendicular to each other to form an L-shaped structure. It can be understood that in order to increase the mating area between the sheet metal support member 63 and the lens bracket 41 and make the connection between the two more firm, the first fastening portion 64 can also be provided in multiple numbers, and the multiple first fastening portions 64 can be spaced apart along the width direction of the sheet metal support member 63. At this time, the lower half of the lens bracket 41 is used to fix the lens assembly 70.

[0093] In a possible embodiment of the present application, in the radial direction of the barrel housing 10, both the first circuit board 61 and the sheet metal support member 63 are located between the cable hole 121 and the opening 11; a part of the inner side wall of the tail end 12 protrudes along the direction close to the front end to form two spaced-apart support protrusions 80. One end of the sheet metal support member 63 close to the tail end is fixed to the support protrusion 80 and is spaced apart from the inner side wall of the tail end 12; wherein, the two support protrusions 80 are respectively located on the left and right sides of the cable hole, so that the sheet metal support member 63, the two support protrusions 80 and the inner side wall of the tail end 12 jointly define a threading channel for the cable 90 to pass through the threading channel and then connect to the cable docking socket 611.

[0094] Specifically, in the radial direction of the barrel housing 10, both the sheet metal support member 63 and the first circuit board 61 are arranged close to the opening 11. Please refer to Figure 1, the opening 11 is provided at the upper part of the barrel body 10, and the cable hole 121 is provided in the middle of the tail end 12. At this time, the first circuit board 61 is located between the opening 11 and the cable hole 121, that is, it is arranged close to the upper part of the barrel body 10. It is easy to understand that if the opening 11 is provided at the top of the barrel housing 10 and the circuit board assembly is arranged at the bottom of the barrel, at this time, the user needs to have a line of sight higher than the opening by a certain height and then adopt a top-down perspective to observe the various components or cable plugging points on the circuit board through the opening. However, generally, the cylindrical camera is installed at a high place. At this time, the cylindrical camera may be close to the ceiling or the protruding eaves on the wall or the bottom of the balcony. That is, the existing installation position of the cylindrical camera does not provide enough observation space for the user to perform maintenance. Or, when the cylindrical camera is installed at a high place, tools such as maintenance ladders do not provide enough height for the user to observe the various components or cable plugging points on the circuit board well through the opening. And it is easy to understand that in the above cases, it is also difficult for the user to quickly perform maintenance operations on the various components or cable plugging points on the circuit board through tools. In this embodiment, both the sheet metal support 63 and the first circuit board 61 are arranged close to the opening 11. That is, at this time, the height required for the user to observe the various components or cable plugging points on the circuit board through the opening 11 from a top-down perspective is smaller. Thus, after the cylindrical camera is installed at the working position, such as on the wall, the maintenance personnel can directly observe the conditions of the various cable docking sockets 611 on the first circuit board 61 after opening the cover member at the opening, and it is convenient for them to perform maintenance through tools or directly by hand, thereby improving the man-machine efficiency of the cylindrical camera and reducing the maintenance difficulty.

[0095] Part of the inner side wall of the tail end 12 protrudes to form two spaced-apart support protrusions 80. Among them, the support protrusion 80 and the tail end 12 are integrally formed parts to reduce the overall number of components of the cylindrical camera. And the integral formation of the support protrusion 80 and the tail end 12 can also improve the structural strength at the tail end 12, so as to better support the wireless communication component 30 at the opening 11.

[0096] The cable of the cylindrical camera enters the accommodation cavity through the cable hole 121 at the tail end 12. Refer to Figure 3 and Figure 4 , in the width direction of the sheet metal support 63, the two support protrusions 80 are spaced apart from each other and are located on both sides of the cable hole 121. The support effect of the two support protrusions 80 on the sheet metal support 63 is not only better, and the two support protrusions 80 are spaced apart from each other. In addition, at least part of the rear end of the sheet metal support 63 is spaced apart from the inner side wall of the tail end 12, which can also facilitate the cable to extend upward through the gap between the two support protrusions 80, so as to facilitate the routing of the cable.

[0097] In a possible embodiment of the present application, two second fastening portions 65 are formed by the end face of one end of the sheet metal support member 63 near the tail end protruding. The two second fastening portions 65 are spaced apart in the width direction of the sheet metal support member 63, so that the two second fastening portions 65 and the two support protruding portions 80 are arranged in one-to-one correspondence. The second fastening portion 65 is lapped and fixed to the side wall of the corresponding support protruding portion 80 facing the opening, so that the sheet metal support member 63 and the support protruding portion 80 are fixedly connected.

[0098] Specifically, please refer to Figures 2 to 4 , the end face of one end of the sheet metal support member 63 near the tail end horizontally protrudes to form two second fastening portions 65, so that each second fastening portion 65 can be directly lapped on the corresponding support protruding portion 80. That is, the second fastening portion 65 on the left is lapped on the support protruding portion 80 on the left, and the second fastening portion on the right is lapped on the support protruding portion 80 on the right. The gap between the two is the aforementioned wire threading channel.

[0099] In this embodiment, the sheet metal support member 63 is connected to the support protruding portion 80 through the two second fastening portions 65, which can make the gap size between the end face of the sheet metal support member 63 and the inner side wall of the tail end larger, so as to leave enough space for the wire 90 to route, making the routing of the wire 90 cleaner, and also facilitating the operator to comb the wire and facilitating their operation.

[0100] In a possible embodiment of the present application, a positioning groove 81 is formed by the end face of one side of one of the support protruding portions 80 away from the tail end being recessed; a positioning portion 66 is formed by the end face of one end of the sheet metal support member 63 near the tail end protruding, and one end of the positioning portion 66 away from the front end extends in a direction away from the opening 11; wherein, the positioning portion 66 extends into the positioning groove 81 and one end of the positioning portion 66 away from the front end abuts against the bottom wall of the positioning groove 81, and in the width direction of the sheet metal support member 63, at least one side edge of the positioning portion 66 abuts against the corresponding groove side wall of the positioning groove 81.

[0101] Specifically, please refer to Figures 2 to 4, a part of the front end face of the support protrusion 80 on the right side is recessed to form a positioning groove 81. In the axial direction of the barrel body housing 10, that is, in the front-rear direction, there is a height difference between the bottom wall of the positioning groove 81 and the front end face of the support protrusion 80, so that a positioning step is formed between the positioning groove 81 and the support protrusion 80. At this time, in order to cooperate with this positioning step, correspondingly, the right side part of the end face of one end of the sheet metal support member 63 close to the tail end 12 also has an L-shaped positioning portion 66. That is to say, the positioning portion 66 includes a horizontal section, the horizontal section is connected to the sheet metal support member 63, and the vertical section is perpendicular to the horizontal section and extends vertically downward. In this way, when installing the camera, the sheet metal support member 63 extends into the accommodation cavity from the installation opening of the open end 13, and the operator positions through the positioning portion 66 and the positioning groove 81. When a part of the positioning portion 66 extends into the positioning groove 81, that is, in the width direction of the sheet metal support member 63, when at least one side edge of the positioning portion 66 abuts against the corresponding groove side wall of the positioning groove 81, the left-right positioning of the second fastening portion 65 is completed. Then the operator continues to push the sheet metal support member 63. When the end face of the vertical section of the positioning portion 66 abuts against the bottom wall of the positioning groove 81, the front-rear positioning of the sheet metal support member 63 is completed. At this time, the two second fastening portions 65 are overlapped with the corresponding support protrusion portions 80.

[0102] In this embodiment, the positioning of the sheet metal support member 63 is realized through the positioning portion 66 and the positioning groove 81 to facilitate the operator to install the camera.

[0103] In addition, in this embodiment, one end of the positioning portion 66 away from the front end is bent and extended in the direction away from the opening 11, that is, vertically downward, which can also prevent the positioning portion 66 from bending upward and affecting the safety and operation of the operator's operation space between the first circuit board 61 and the opening 11.

[0104] In a possible embodiment of the present application, the support protrusion 80 is exposed by the opening 11; a mating hole 82 is provided on the side wall of the support protrusion 80 facing the opening 11; the camera further includes a fastener (not shown), and the fastener passes through the second fastening portion 65 and is threadedly engaged with the mating hole.

[0105] Specifically, please refer to Figure 4 , in order to facilitate the operator to disassemble and assemble the sheet metal support member 63 through the opening 11, the support protrusion 80 extends to be exposed by the opening 11, that is, it extends deep into the operation space corresponding to the opening 11. At this time, a mating hole 82 is provided on the upper wall surface of the support protrusion 80, and the operator can fasten the second fastening portion 65 to the support protrusion 80 through the threaded engagement of fasteners such as screws and bolts and the mating hole 82.

[0106] In a possible embodiment of the present application, the communication component 30 includes: a module bracket 31, a wireless communication module 32, and a connecting line. The module bracket 31 is detachably connected to the opening 11, and the module bracket 31 is spaced apart from the side wall of the cover member 20 facing the accommodation cavity to jointly define a module accommodation area; the wireless communication module 32 is disposed in the module accommodation area, and the wireless communication module 32 includes at least one of an antenna module or a radar module. One end of the connecting line is connected to the module bracket, and the other end passes through the through hole and extends into the accommodation cavity to cooperate with a connecting line docking socket on the side wall of the first circuit board 61 facing the opening, so as to be electrically connected to the second circuit board 62 through the first circuit board 61.

[0107] It can be understood that the communication component 30 can be directly installed on the side wall of the cover member 20 facing the accommodation cavity, that is, on the inner side wall of the cover member 20, so as to dispose the communication component 30 at the opening 11. Alternatively, referring to Figure 1 , Figure 5 and Figure 6 , since the cover member 20 is a plastic part and its structural strength is limited, in order to better support the communication component 30, this embodiment further provides a module bracket 31. The module bracket 31 is a support component, and the wireless communication module 32 is an execution component. The wireless communication module 32 is fixed at the opening 11 through the module bracket 31. Among them, the module bracket 31 can be configured as a sheet metal part, and its shape matches the shape of the opening 11. Thus, as an option in this embodiment, its outer edge can be lapped at the opening 11, and then when the cover member 20 is fastened to the barrel body housing 10 by screws, the module bracket 31 is fixed at the opening 11. Alternatively, as another option in this embodiment, the module bracket 31 can also be detachably connected to the barrel body housing 10 independently through snap-fit, slot insertion, etc., and then the cover member 20 is connected to the module bracket 31 or the barrel body housing 10.

[0108] In addition, as an option in this embodiment, the module bracket 31 can be configured as a flat sheet metal part. Alternatively, as another option in this embodiment, referring to Figure 5 , in order to improve the structural strength of the module bracket 31, the cross-section of the module bracket 31 can also be configured as a "ji" shape, that is, the module bracket 31 includes a middle horizontal support plate and side vertical plates respectively connected to both sides of the middle support plate, and the side of the side vertical plate away from the middle vertical plate is bent away from the middle support plate to form a connecting flange. At this time, the wireless communication module 32 can be fixed on the middle horizontal support plate by screws, bonding or other equivalent methods.

[0109] The wireless communication module 32 includes, but is not limited to, an antenna module or a radar module, and can include at least one of an antenna module or a radar module. At this time, corresponding connection ports can be provided on the module bracket 31 to facilitate function expansion of the cylindrical camera.

[0110] At this time, in order to facilitate wire routing, through holes are provided on the module support 31, and the module accommodation area communicates with the accommodation cavity through the through holes; the connecting wire 33 required by the wireless communication module 32 passes through the through holes and extends into the accommodation cavity to cooperate with the connecting wire docking socket on the side wall of the first circuit board 61 facing the opening, so as to be electrically connected to the second circuit board 62 through the first circuit board 61. That is, the power module of the second circuit board 62 supplies power to the wireless communication module through the second circuit board 62, the first circuit board 61, the connecting wire docking socket and the connecting wire 33.

[0111] It can be understood that the connecting wire docking socket is also exposed by the opening 11, which facilitates the user to disassemble and assemble the connecting wire. That is, when the first circuit board 61 needs to be repaired, the operator opens the covering member 20 and then removes the fasteners on the module support 31 to separate the module support 31 from the barrel body housing 10 at the opening 11. At this time, due to the connection of the connecting wire 33, the module support 31 is still suspended on the barrel body housing 10 by the connecting wire. However, it does not affect the opening of the opening 11. The operator can visually observe each structure in the accommodation cavity and separate the connecting wire 33 and the connecting wire docking socket by using tools or manually. Only then can the module support 31 be removed.

[0112] Alternatively, the connecting wire 33 can also be detachably connected to the wireless communication module 32. At this time, after the operator opens the covering member 20, the connecting wire 33 is first separated from the wireless communication module 32, and then the fasteners on the module support 31 are removed to completely separate the module support 31 from the barrel body housing 10 at the opening 11.

[0113] The above are only optional embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the inventive concept of the present application by using the content of the specification and drawings of the present application, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present application.
