[0026] In order to more fully understand the technical content of the present invention, the technical solution of the present invention is further introduced and illustrated below in conjunction with schematic diagrams, but is not limited thereto.

[0027] Reference Figures 1 to 5 , Figures 1 to 5 A specific embodiment of the network camera 100 of the present invention is shown. In the embodiment shown in the drawings, the network camera 100 includes a housing 10, a heat-conducting component and a camera module 20, wherein the camera module 20 is mounted on the housing 10, and includes a lens barrel 21, a lens module 22 and a main board 23 from front to back, the lens barrel 21 is mounted on the front panel 111 of the housing 10, the lens module 22 and the main board 23 are located in the housing 10, and the lens 222 of the lens module 22 faces the lens barrel 21 and is correspondingly plugged into the rear end of the lens barrel 21, the main board 23 is electrically connected to the lens module 22, and the main board 23 is thermally connected to the housing 10 through the heat-conducting component. Understandably, when the network camera 100 is working, the temperature rise of the main board 23 is the highest, and the temperature rise of the lens module 22 is second. In the present invention, the lens barrel 21, the lens module 22 and the main board 23 are arranged on the housing 10 in sequence, and the lens module 22 is directly plugged into the rear end of the lens barrel 21, which greatly shortens the assembly dimension chain from the lens 222 in the lens module 22 to the lens barrel 21, so that the components of the network camera 100 of the present invention are closely arranged and connected, and the internal space structure of the housing 10 is reasonably utilized, so that its volume can be reasonably reduced, the weight is light, and the demand for product miniaturization can be met, and the lens can be made The assembly tolerance of the head 222 to the lens barrel 21 is smaller, ensuring good concentricity between the lens 222 and the lens barrel 21, and while meeting the miniaturization of the product, the heat generated by the lens module 22 and the main board 23 can be dissipated, which is beneficial to the internal heat dissipation of the network camera 10, that is, by conducting most of the heat generated by the main board 23 during operation to the housing 10 through the heat conduction component, and radiating from the housing 10 to the external environment for heat dissipation, the heat generated by the lens module 22 is directly conducted to the lens barrel 21 for heat dissipation, which can meet the problem of internal heat dissipation of the small network camera 100 and meet the heat dissipation requirements of the whole product. In some embodiments, the lens barrel 21 can be a metal lens barrel or a plastic lens barrel, both of which can directly / indirectly contact with the lens module 22 to dissipate heat. Preferably, the plastic lens barrel is made of modified plastic with thermal conductivity. When the lens barrel 21 is a metal lens barrel or a modified plastic lens barrel, the heat generated by the lens module 22 can be quickly dissipated after being conducted to the lens barrel 21, further solving the problem of internal heat dissipation of the small network camera 100 and further meeting the heat dissipation requirements of the entire product.

[0028] In the present invention, the main board 23 is used to control the operation of the lens module 22. The lens module 22 is used for shooting images and includes a PCBA 221 and a lens 222 connected to the PCBA 221. A dustproof foam 25 can also be arranged between the lens barrel 21 and the lens 222 to effectively prevent dust from entering the lens and also to play a role in buffering and shock reduction.

[0029] Specifically, in this embodiment, at least one first positioning hole 211 is provided on the side of the lens barrel 21 opposite to the lens module 22, and a plug-in portion 223 is provided on the PCBA 221 of the lens module 22, and the plug-in portion 223 is connected to the lens barrel 21 in a manner that the plug-in portion 223 is correspondingly plugged into the first positioning hole 211. In the present invention, one or more first positioning holes 211 can be provided according to installation requirements, preferably, as shown in FIG. Figure 4 As shown, in the embodiment shown in the accompanying drawings, two first positioning holes 211 are provided, and the two first positioning holes 211 are respectively opened at the upper part and the lower part of the inner circumference 212 of the lens barrel 21. Figure 2 In this embodiment, the plug-in portion 223 is a copper column protruding toward the lens barrel 21, and the copper column is arranged one-to-one with the first positioning hole 211, and after plugging, the lens barrel 21 and the PCBA 221 can be further fixed by a locking screw. In the present invention, the copper column can be welded on the PCBA 221 by the SMT process for positioning and plugging. It can be understood that in some other embodiments, the first positioning hole 211 can be opened on the PCBA 221 of the lens module 22, and the plug-in portion 223 can be correspondingly arranged on the side of the lens barrel 21 opposite to the lens module 22, which can also realize the positioning plug-in connection between the lens module 22 and the lens barrel 21. Based on the above design, the present invention ensures that the positioning concentricity between the lens 222 and the lens barrel 21 in the lens module 22 is higher through the positioning plug-in cooperation of the plug-in portion 223 and the first positioning hole 211, and has better concentricity. Even if it is affected by falling during use, the deviation between the lens 222 and the lens barrel 21 is also small, and the lens module 22 is directly fixed on the lens barrel 21, which can greatly shorten the assembly dimension chain of the lens 22 to the lens barrel 21, making the assembly tolerance smaller, and can give full play to the optical performance of the lens module 22, improve the photo-taking and video-taking effects of the network camera 100, and bring people a better visual experience.

[0030] In some embodiments, the housing 10 may be a plastic housing, including a front housing 11 and a rear cover 12 disposed at the rear end of the front housing 11 and forming an accommodation space 113 with the front housing 11. In this embodiment, the lens barrel 21 is mounted at the front end of the front housing 11, that is, mounted on the front panel 111, and the lens module 22, the main board 23 and the heat conducting component are all located in the accommodation space 113. Preferably, as Figure 2and Figure 3 As shown, in this embodiment, the network camera 100 may also include a heat sink 40 located in the accommodating space 113, the heat sink 40 includes a metal plate 41 and a plurality of heat sink fins 42 extending outward from the back of the metal plate 41, the heat sink 40 is located between the main board 23 and the back cover 12 of the housing 10, and the front of the metal plate 41 is close to the main board 23. Based on the above design, the heat sink fins 42 can further increase the heat dissipation area. Since the heat sink 40 has a large thermal conductivity, the heat generated by the main board 23 can also be concentrated and stored on the heat sink 40. The heat sink 40 can be equivalent to a heat storage device, which is in contact with the air in the housing 10 and can gradually conduct the heat to the back cover 12 through the heat sink fins 42. The back cover 12 is made of plastic, and its thermal resistance is lower than that of metal materials. When the network camera 100 is working, it can avoid making the overall temperature of the back cover 12 in the housing 10 too high, thereby avoiding burns.

[0031] Furthermore, if Figure 2 , Figure 3 and Figure 5 As shown, the network camera 100 further includes a fourth heat-conducting member 50, and the mainboard 23 is thermally connected to the heat sink 40 through the fourth heat-conducting member 50. In this embodiment, the mainboard 23 contacts the metal plate 41 in the heat sink 40 through the fourth heat-conducting member 50, and the fourth heat-conducting member 50 can be thermal grease or other thermal conductive medium materials. It can be understood that the heat sink 40 can be attached to the back cover 12 of the housing 10 through the thermal conductive adhesive 43, that is, it can be installed on the back cover 12 by gluing, and the heat can also be slowly conducted to the back cover 12 through the thermal conductive adhesive 43.

[0032] In the embodiment shown in the drawings, the heat-conducting assembly includes a first heat-conducting member 31 and a heat-conducting metal member 32, the first heat-conducting member 31 and the heat-conducting metal member 32 are respectively located on both sides of the lens module 22, the first heat-conducting member 31 is connected between the main board 23 and the lens module 22, and the lens module 22 is thermally connected to the housing 10 through the heat-conducting metal member 32. Preferably, in this embodiment, the lens module 22 is thermally connected to the front panel 111 of the housing 10 through the heat-conducting metal member 32, the heat-conducting metal member 32 is preferably a heat-conducting aluminum member, and the first heat-conducting member 31 can be a thermally conductive silicone grease. Based on the above design, when the lens module 22 is working, the main heat is mainly generated by the PCBA 221. The heat on the PCBA 221 can be directly transferred to the lens barrel 21 for heat dissipation, and can also be transferred to the front panel 111 for heat dissipation through the heat-conducting metal piece 32. The main board 23 is thermally connected to the lens module 22 through the first heat-conducting piece 31. The heat generated by the main board 23 can not only be dissipated through the heat sink 40, but also part of the heat generated by the main board 23 can be quickly transferred through the lens module 22 and the heat-conducting metal piece 32 to the lens barrel 21 and the front panel 111, which is less contacted by the user, through the first heat-conducting piece 31. The panel 111 radiates to the external environment to meet the heat dissipation requirements. The heat generated by the mainboard 23 and the lens module 22 can produce a thermal conductivity difference in the front and rear directions of the network camera 100 through the heat-conducting component and the heat sink 40. Targeted and quantitative heat conduction is performed on the areas that the user may touch, so that the temperature around the front shell 11 and the back cover 12 that the user mainly touches when taking the camera is lower, which can provide the user with a more suitable touch temperature. While meeting the product miniaturization and heat dissipation requirements of the whole machine, different areas of the shell 10 can have a suitable heat dissipation temperature, so that the touch temperature when the user takes the camera is more suitable, which can improve the user experience.

[0033] Furthermore, in some embodiments, one side of the heat-conducting metal member 32 surrounds the lens 222 and is attached to the PCBA 221, and the other side is attached to the inner wall of the front panel 111, and the PCBA 221 is electrically connected to the main board 23. In this embodiment, the PCBA 221 is electrically connected to the main board 23 via a flat cable 90, which is a flexible flat cable that is easy to connect and can save space; in some other embodiments, the PCBA 221 can also be electrically connected to the main board 23 via a board-to-board connector. Figure 2 and Figure 3 As shown, in this embodiment, a groove 112 is opened on the inner wall of the front panel 111 corresponding to the heat-conducting metal part 32, and the heat-conducting metal part 32 can be adhered to the groove 112 on the inner wall of the front panel 111 in an adhesive manner through a heat-conducting thin layer material 34, and the heat-conducting thin layer material 34 can be a heat-conducting adhesive, etc.

[0034] Furthermore, the heat-conducting component also includes at least two heat-conducting metal sheets 33. The left inner wall and / or the right inner wall of the front shell 11 are provided with at least one of the heat-conducting metal sheets 33; the top wall and / or the bottom wall of the front shell 11 are provided with at least one of the heat-conducting metal sheets 33, and the heat-conducting metal sheets 33 are in contact with the lens module 22, that is, at least one of the long sides (top wall, bottom wall) and at least one of the short sides (left inner wall, right inner wall) of the shell 10 is provided with at least one heat-conducting metal sheet 33. The heat-conducting metal sheets 33 are provided to accelerate the heat dissipation of the lens module 22 on the one hand, and on the other hand, they can cooperate with external supporting equipment through magnetic attraction to realize the rapid switching of the horizontal and vertical shooting of the lens 222. Figure 2 As shown, in this embodiment, the heat-conducting component also includes four heat-conducting metal sheets 33. The left inner wall and the right inner wall of the front shell 11 are each provided with a heat-conducting metal sheet 33, and the bottom wall of the front shell 11 is provided with two heat-conducting metal sheets 33. The four heat-conducting metal sheets 33 are all in contact with the lens module 22, so that part of the heat generated by the lens module 22 and part of the heat conducted to the lens module 22 can also be dissipated through the heat-conducting metal sheets 33, thereby further accelerating the heat dissipation. Understandably, in some embodiments, four heat-conducting metal sheets 33 can also be respectively arranged on the left inner wall, right inner wall, top wall and bottom wall of the front shell body 11; and in some other embodiments, the number of the heat-conducting metal sheets 33 can be increased or decreased according to the size of the shell body 10 of the network camera 100. For example, it can also be set to three sheets, and the three heat-conducting metal sheets 33 can be respectively distributed on the left inner wall, right inner wall and bottom wall of the front shell body 11; or, it can also be set to five or six sheets, etc., and the specific distribution position of the heat-conducting metal sheets 33 can be adjusted according to actual needs.

[0035] Preferably, in some embodiments, the network camera 100 also includes a conductive component, and the conductive component includes a first conductor 61 and a second conductor 62. The first conductor 61 and the second conductor 62 are respectively fixed between the main board 23 and the camera module 20 and between the main board 23 and the metal plate 41, and the first conductor 61 and the second conductor 62 are respectively located on both sides of the main board 23 to avoid malfunctions caused by poor conductivity, can prevent static electricity, and can also play a role in buffering and shock absorption when the network camera 100 falls.

[0036] In some embodiments, the network camera 100 further includes a MIC component 70, which is installed on the inner wall of the housing 10 and connected to the mainboard 23 via a first cable to provide a sound receiving function. Figure 2As shown, the camera module 20 also includes a light guide column 224 and an LED lamp bead, the LED lamp bead is arranged on the main board 23 and connected to the main board 23, one end of the light guide column 224 is fixed on the main board 23 and covers the LED lamp bead, then the PCBA 221 of the lens module 22 is provided with a notch corresponding to the position of the light guide column 224, the other end of the light guide column 224 passes through the notch and is exposed to the front panel 111 of the shell 10, so as to control and guide the light, so that the light emitted by the LED lamp bead is emitted outward through the light guide column 224, so as to indicate the working status of the network camera 100, for example, a red light can indicate that the network camera 100 is in a video recording state at this time, and a blue light can indicate that the network camera 100 is in a photo taking state, etc. It is understandable that in some other embodiments, the LED lamp bead can also be set on the PCBA221 of the lens module 22 and connected to the lens module 22, one end of the light guide column 224 can be fixed on the PCBA221 and covered on the LED lamp bead, and the other end is exposed on the front panel 111.

[0037] In some embodiments, the lens barrel 21 is equipped with a lens 24, and the network camera 100 further includes an annular magnet 80. The peripheral surface of the lens barrel 21 near the lens 24 is inwardly concave to form an annular placement groove 213. The annular magnet 80 is installed in the placement groove 213 of the lens barrel 21, and the magnetic poles of the two half rings of the annular magnet 80 are different (such as Figure 2As shown in the figure, N and S respectively represent the magnetic poles of the annular magnet 80). Preferably, in this embodiment, the annular magnet 80 is composed of two arc-shaped magnets connected end to end, and the polarities of the magnetic poles of the two arc-shaped magnets are different by magnetizing the left and right halves, and the lens barrel 21 can be made of stainless iron material. In some other embodiments, the magnetic poles of the two half rings in the annular magnet 80 can also be the same. The annular magnet 80 can be an integrated annular magnet, or an annular magnet composed of three or more arc-shaped magnets connected end to end in sequence. By adopting different magnetizing methods, the polarities of the magnetic poles of the two half rings in the annular magnet 80 can also be different or the same; and the lens barrel 21 can also be made of a metal material with good magnetic conductivity. Based on the above design, the annular magnet 80 in the present invention is installed in the placement groove 213 of the lens barrel 21 and contacts with the lens barrel 21. The lens barrel 21 has good magnetic conductivity, which is equivalent to a magnetic conductive sheet and plays a magnetic conductive role. The leakage magnetic flux of the end face of the annular magnet 80 in contact with the lens barrel 21 can form a complete short-distance magnetic conductive loop through the lens barrel 21, which effectively improves the magnetic circuit, can greatly reduce the leakage magnetic flux of the annular magnet 80, and enhance the magnetic strength of the annular magnet 80. Without changing the volume of the magnet 80, it can also provide a stronger magnetic attraction, and achieve the effect of a small magnet having a large magnetic force, that is, the size of the magnet 80 can be reduced under the same magnetic strength, thereby reducing the magnet cost, and at the same time, it can also save space to a greater extent, so that the overall size of the camera module 20 is reduced, making the structural design of the product more compact and more competitive; and the entire annular magnet 80 is magnetized in a half-magnetization manner, so that the magnetic poles of the two half rings in the annular magnet 80 are different in polarity, and the two half rings in the annular magnet 80 can also form a magnetic loop through the lens barrel 21 to further reduce the leakage magnetic flux of the magnet.

[0038] In summary, in the network camera of the present invention, the lens barrel, the lens module and the mainboard electrically connected to the lens module are arranged on the shell from front to back in sequence, and the lens module is plugged into the rear end of the lens barrel, and the various components are closely arranged and connected, so that the internal space of the network camera is reasonably utilized, so that its volume can be reasonably reduced, and the lens module is directly plugged into the lens barrel, which not only greatly shortens the assembly dimension chain from the lens in the lens module to the lens barrel, further reduces the shell volume, and can also reduce the weight. It can be put into a pocket or bag when carried, and can also make the assembly tolerance smaller, ensuring that the lens in the lens module and the lens barrel have good concentricity. At the same time, part of the heat generated by the lens module and part of the heat conducted to the lens module by the mainboard can be directly conducted to the lens barrel, so that the heat is quickly dissipated through the lens barrel, and the remaining very small part of the heat can also be dissipated by the surrounding heat-conducting metal sheets, and part of the heat generated by the mainboard can be transferred to the heat sink provided with heat dissipation fins for heat dissipation. The first heat-conducting component can also gradually conduct heat to the back cover, and the back cover is made of plastic, and its thermal resistance is lower than that of metal materials. When the network camera is working, the overall temperature of the back cover in the shell can be prevented from being too high, so as to avoid burns. The other part of the heat generated by the mainboard can be quickly conducted to the lens module through the first heat-conducting component, and then conducted to the lens barrel and the front panel that the user rarely touches through the heat-conducting metal component and the heat-conducting thin layer material, so as to radiate to the external environment, meet the heat dissipation requirements, avoid heat accumulation causing severe heating or local overheating to damage internal components, and generate heat conductivity differences in the front and back directions of the network camera, and carry out targeted and quantitative heat conduction for the areas that the user may touch, so that the temperatures around the front shell and the back cover that the user mainly touches when taking the camera are lower, so as to give the user a more suitable touch temperature. While meeting the miniaturization of the product and the heat dissipation requirements of the whole machine, different areas of the shell can have a suitable heat dissipation temperature, so that the touch temperature when the user takes the camera is more suitable, which can improve the user experience.
