[0026] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0027] Reference Figures 1 to 5 , Figures 1 to 5A specific embodiment of the network camera 100 of this utility model is shown. In the embodiment shown in the accompanying drawings, the network camera 100 includes a housing 10, a heat-conducting component, and a camera module 20. The camera module 20 is mounted on the housing 10 and includes, from front to back, a lens barrel 21, a lens module 22, and a main board 23. 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 inside the housing 10, and the lens 222 of the lens module 22 faces the lens barrel 21 and is correspondingly inserted 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, the motherboard 23 experiences the highest temperature rise during network camera 100 operation, followed by the lens module 22. In this invention, the lens barrel 21, lens module 22, and motherboard 23 are arranged sequentially on the housing 10, with the lens module 22 directly inserted into the rear end of the lens barrel 21. This significantly shortens the assembly dimension chain from the lens 222 to the lens barrel 21, allowing for a tighter connection of all components in the network camera 100. This makes efficient use of the internal space of the housing 10, resulting in a smaller size and lighter weight, meeting the requirements for product miniaturization. The smaller assembly tolerance between the lens 222 and the lens barrel 21 ensures better concentricity between them. Furthermore, while achieving product miniaturization, the heat generated by both the lens module 22 and the motherboard 23 can be dissipated, which is beneficial for the internal heat dissipation of the network camera 10. Specifically, most of the heat generated by the motherboard 23 during operation is conducted to the housing 10 through heat-conducting components, and then radiated to the external environment by the housing 10 for heat dissipation. The heat generated by the lens module 22 is directly conducted to the lens barrel 21 for heat dissipation, thus solving the internal heat dissipation problem of the small network camera 100 and meeting the overall heat dissipation requirements of the product. In some embodiments, the lens barrel 21 can be a metal or plastic lens barrel, both of which can directly or indirectly contact the lens module 22 for heat dissipation. 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 conducted to the lens barrel 21 and dissipated quickly, further solving the problem of heat dissipation inside the small network camera 100 and further meeting the heat dissipation requirements of the whole product.

[0028] In this utility model, the motherboard 23 is used to control the operation of the lens module 22, which is used for shooting and imaging. The lens module 22 includes a PCBA 221 and a lens 222 connected to the PCBA 221. A dustproof foam 25 can also be provided between the lens barrel 21 and the lens 222 to effectively prevent dust from entering the lens and to provide cushioning and shock absorption.

[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. The PCBA 221 of the lens module 22 is provided with a connector 223, which is connected to the lens barrel 21 by correspondingly inserting into the first positioning hole 211. In this invention, one or more first positioning holes 211 can be provided according to installation requirements. Preferably, as shown in the figure... Figure 4 As shown in the attached figure, in the embodiment, two first positioning holes 211 are provided. The two first positioning holes 211 are respectively opened in the upper and lower parts of the inner peripheral portion 212 of the lens barrel 21. Continuing to refer to... Figure 2 In this embodiment, the insertion part 223 is a copper pillar protruding towards the lens barrel 21. The copper pillar is correspondingly arranged with the first positioning hole 211, and after insertion, the lens barrel 21 and the PCBA 221 can be further fixed by locking screws. In this utility model, the copper pillar can be soldered onto the PCBA 221 by SMT process for positioning and insertion. Understandably, in some other embodiments, the first positioning hole 211 can be opened on the PCBA 221 of the lens module 22, and the insertion part 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 and insertion connection between the lens module 22 and the lens barrel 21. Based on the above design, this utility model ensures a higher degree of concentricity between the lens 222 and the lens barrel 21 in the lens module 22 through the positioning and insertion cooperation of the insertion part 223 and the first positioning hole 211. It has better concentricity, and even if it is affected by drops, the deviation between the lens 222 and the lens barrel 21 is small. Moreover, the lens module 22 is directly fixed on the lens barrel 21, which can greatly shorten the assembly dimension chain from the lens 22 to the lens barrel 21, making the assembly tolerance smaller. It can give full play to the optical performance of the lens module 22, improve the photo and video effects of the network camera 100, and bring people a better visual experience.

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

[0031] Furthermore, such as Figure 2 , Figure 3 and Figure 5 As shown, the network camera 100 also includes a fourth heat-conducting component 50, and the motherboard 23 is thermally connected to the heat sink 40 through the fourth heat-conducting component 50. In this embodiment, the motherboard 23 contacts the metal plate 41 in the heat sink 40 through the fourth heat-conducting component 50. The fourth heat-conducting component 50 can be thermal grease or other thermally conductive media. Understandably, the heat sink 40 can be attached to the back cover 12 of the housing 10 by thermally conductive adhesive 43, that is, it can be installed on the back cover 12 by adhesive method. At the same time, heat can also be slowly conducted to the back cover 12 through the thermally conductive adhesive 43.

[0032] In the embodiment shown in the accompanying drawings, the heat-conducting component includes a first heat-conducting element 31 and a heat-conducting metal element 32. The first heat-conducting element 31 and the heat-conducting metal element 32 are respectively located on both sides of the lens module 22. The first heat-conducting element 31 is connected between the motherboard 23 and the lens module 22. The lens module 22 is thermally connected to the housing 10 through the heat-conducting metal element 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 element 32. The heat-conducting metal element 32 is preferably a heat-conducting aluminum element, and the first heat-conducting element 31 can be thermal grease. Based on the above design, when the lens module 22 is working, the main heat is generated by the PCBA 221. The heat on the PCBA 221 can be directly conducted to the lens barrel 21 for heat dissipation, or it can be conducted to the front panel 111 for heat dissipation through the heat-conducting metal component 32. The motherboard 23 is thermally connected to the lens module 22 through the first heat-conducting component 31. The heat generated by the motherboard 23 can not only be dissipated through the heat sink 40, but also through the first heat-conducting component 31, which can quickly conduct some of the heat generated by the motherboard 23 to the lens barrel 21 and the front panel 111, which is less frequently touched by the user, through the lens module 22 and the heat-conducting metal component 32. The panel 111 radiates heat to the external environment to meet the heat dissipation requirements. The heat-conducting components and heat sink 40 can create a heat conduction difference in the front and rear directions of the network camera 100, so that the heat generated by the motherboard 23 and the lens module 22 can be directed and quantitatively conducted to the areas that the user may touch. This results in a lower temperature around the front shell 11 and the rear cover 12 that the user mainly touches when picking it up, providing the user with a more suitable touch temperature. While meeting the requirements of product miniaturization and overall heat dissipation, it can also ensure that different areas of the shell 10 have a suitable heat dissipation temperature, making the touch temperature more suitable when the user picks it up, thus improving the user experience.

[0033] Furthermore, in some embodiments, one side of the heat-conducting metal component 32 is attached to the PCBA 221 around the lens 222, and the other side is attached to the inner wall of the front panel 111. The PCBA 221 is electrically connected to the motherboard 23. In this embodiment, the PCBA 221 is electrically connected to the motherboard 23 via a ribbon cable 90. The ribbon cable 90 is a flexible ribbon cable, which is easy to connect and saves space. In some other embodiments, the PCBA 221 can also be electrically connected to the motherboard 23 via a board-to-board connector. Figure 2 and Figure 3 As shown, in this embodiment, a groove 112 is provided on the inner wall of the front panel 111 corresponding to the heat-conducting metal part 32. The heat-conducting metal part 32 can be attached to the groove 112 on the inner wall of the front panel 111 by means of a heat-conducting thin layer material 34. The heat-conducting thin layer material 34 can be heat-conducting adhesive, etc.

[0034] Furthermore, the heat-conducting component also includes at least two heat-conducting metal sheets 33. At least one heat-conducting metal sheet 33 is provided on the left inner wall and / or right inner wall of the front housing 11; at least one heat-conducting metal sheet 33 is provided on the top wall and / or bottom wall of the front housing 11, and the heat-conducting metal sheet 33 contacts the lens module 22. That is, at least one heat-conducting metal sheet 33 is provided on at least one side of the long side (top wall, bottom wall) and at least one side of the short side (left inner wall, right inner wall) of the housing 10. The heat-conducting metal sheets 33 are provided to accelerate heat dissipation from the lens module 22, and can also cooperate with external support devices via magnetic attraction to achieve rapid switching between 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. One heat-conducting metal sheet 33 is provided on the left inner sidewall and the right inner sidewall of the front housing 11, and two heat-conducting metal sheets 33 are provided on the bottom wall of the front housing 11. All four heat-conducting metal sheets 33 are in contact with the lens module 22, so that some of the heat generated by the lens module 22 and some of the heat conducted to the lens module 22 can be dissipated through the heat-conducting metal sheets 33, thereby further accelerating heat dissipation. Understandably, in some embodiments, the four heat-conducting metal sheets 33 may be respectively disposed on the left inner wall, right inner wall, top wall and bottom wall of the front housing 11; while in some other embodiments, the number of heat-conducting metal sheets 33 may be increased or decreased according to the size of the housing 10 of the network camera 100. For example, it may be set to three sheets, and the three heat-conducting metal sheets 33 may be respectively distributed on the left inner wall, right inner wall and bottom wall of the front housing 11; or it may be set to five or six sheets, etc., and the specific distribution position of the heat-conducting metal sheets 33 may be adjusted according to actual needs.

[0035] Preferably, in some embodiments, the network camera 100 further includes a conductive component, which includes a first conductor 61 and a second conductor 62. The first conductor 61 and the second conductor 62 are respectively fixed between the motherboard 23 and the camera module 20 and between the motherboard 23 and the metal plate 41. The first conductor 61 and the second conductor 62 are respectively located on one side of the motherboard 23 to avoid failures caused by poor conductivity, prevent static electricity, and also play a role in cushioning and shock absorption when the network camera 100 is dropped.

[0036] In some embodiments, the network camera 100 further includes a microphone component 70, which is mounted on the inner sidewall of the housing 10 and connected to the motherboard 23 via a first ribbon cable to provide audio recording functionality. And as... Figure 2As shown, the camera module 20 also includes a light guide post 224 and LED beads. The LED beads are disposed on the motherboard 23 and connected to the motherboard 23. One end of the light guide post 224 is fixed on the motherboard 23 and covers the LED beads. The PCBA 221 of the lens module 22 has a notch corresponding to the position of the light guide post 224. The other end of the light guide post 224 passes through the notch and is exposed on the front panel 111 of the housing 10 to control and guide the light, so that the light emitted by the LED beads passes through the light guide post 224 and is emitted outward to indicate the working status of the network camera 100. For example, a red light can indicate that the network camera 100 is in video recording mode, and a blue light can indicate that the network camera 100 is in photo taking mode, etc. Understandably, in some other embodiments, the LED beads may also be disposed on the PCBA221 of the lens module 22 and connected to the lens module 22. One end of the light guide post 224 may be fixed on the PCBA221 and covered on the LED beads, while the other end is exposed on the front panel 111.

[0037] In some embodiments, a lens 24 is mounted on the lens barrel 21, and the network camera 100 further includes an annular magnet 80. An annular placement groove 213 is formed by an inwardly recessed circumferential surface of the lens barrel 21 near the lens 24. The annular magnet 80 is installed within the placement groove 213 of the lens barrel 21, and the magnetic poles of the two halves of the annular magnet 80 have opposite polarities (e.g., ...). Figure 2As shown in the figure, N and S represent the magnetic poles of the ring magnet 80, respectively. Preferably, in this embodiment, the ring magnet 80 is composed of two arc-shaped magnets connected end to end, and is magnetized in a left-right half manner. The magnetic poles of the two arc-shaped magnets have opposite polarities. The lens barrel 21 can be made of stainless iron. In some other embodiments, the magnetic poles of the two halves of the ring magnet 80 can also be the same. The ring magnet 80 can be a one-piece ring magnet, or it can be a ring magnet composed of three or more arc-shaped magnets connected end to end in sequence. By using different magnetization methods, the magnetic poles of the two halves of the ring magnet 80 can also be made of opposite or the same polarities. The lens barrel 21 can also be made of a metal material with good magnetic permeability. Based on the above design, in this utility model, the annular magnet 80 is installed in the placement groove 213 of the lens barrel 21 and contacts the lens barrel 21. The lens barrel 21 has good magnetic conductivity, which is equivalent to a magnetic sheet and plays a magnetic guiding role. The magnetic leakage of the end face of the annular magnet 80 in contact with the lens barrel 21 can form a complete short-distance magnetic conduction circuit through the lens barrel 21, which effectively improves the magnetic circuit, can greatly reduce the magnetic leakage of the annular magnet 80, enhance the magnetic strength of the annular magnet 80, and can provide stronger magnetic attraction without changing the volume of the magnet 80. It achieves the effect of a small magnet with a large magnetic force, that is, the size of the magnet 80 can be reduced under the same magnetic strength, thereby reducing the cost of the magnet. At the same time, it can also save space to a greater extent, making the overall size of the camera module 20 smaller, making the product structure design more compact and more competitive. Furthermore, the entire annular magnet 80 is magnetized by half-magnetizing, so that the magnetic poles of the two halves of the annular magnet 80 are opposite. The two halves of the annular magnet 80 can also form a magnetic circuit through the lens barrel 21 to further reduce the magnetic leakage of the magnet.

[0038] In summary, in this utility model of a network camera, the lens barrel, lens module, and mainboard electrically connected to the lens module are arranged sequentially from front to back on the housing, with the lens module inserted into the rear end of the lens barrel. The components are tightly connected, making efficient use of the internal space of the network camera and allowing for a reasonable reduction in size. Furthermore, the direct insertion of the lens module into the lens barrel significantly shortens the assembly dimension chain from the lens to the lens barrel, further reducing the housing volume and weight, making it easy to carry in a pocket or bag. It also allows for smaller assembly tolerances, ensuring better concentricity between the lens and the lens barrel in the lens module. Simultaneously, some of the heat generated by the lens module and some heat conducted from the mainboard to the lens module can be directly conducted to the lens barrel for rapid heat dissipation. The remaining minimal heat can be dissipated by the surrounding heat-conducting metal plates, and some heat generated by the mainboard can be transferred to a heat sink with cooling fins for further heat dissipation. The heat-conducting component can also gradually conduct heat to the back cover, which is made of plastic with lower thermal resistance than metal materials. This prevents the overall temperature of the back cover from becoming too high during network camera operation, thus avoiding burns. Another portion of the heat generated by the motherboard can be quickly conducted to the lens module through the first heat-conducting component, and then through the heat-conducting metal components and thin heat-conducting material to the lens barrel and the front panel, which is less frequently touched by the user. This radiates heat to the external environment, meeting heat dissipation requirements and preventing heat buildup that could cause severe overheating or localized overheating that could damage internal components. Furthermore, the heat conduction difference in the front and rear directions of the network camera allows for targeted and quantitative heat conduction in areas that the user might touch. This ensures that the areas around the front housing and the back cover, which are the main points of contact when the user handles the camera, are at a lower temperature, providing a more comfortable touch temperature. This design satisfies the requirements for product miniaturization and overall heat dissipation while ensuring that different areas of the housing have suitable temperatures, resulting in a more comfortable touch temperature and improved user experience.

[0039] The above preferred embodiments should be regarded as illustrative examples of the implementation of the present utility model. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present utility model should be considered within the scope of protection of this patent.
