Description

Technical Field

[0001] This application belongs to the field of camera technology, and in particular relates to a camera. Background Technology

[0002] In the field of outdoor security monitoring, cameras need to have good waterproof performance to cope with complex weather conditions. Currently, conventional outdoor cameras are mostly installed using universal ball joints, a structure that allows users to manually adjust the camera's monitoring angle during deployment. However, this solution only supports static adjustment; once installed, the camera cannot be dynamically adjusted according to real-time monitoring needs. To achieve dynamic monitoring capabilities, some solutions introduce motor-driven mechanisms. However, in practical applications, it is difficult to achieve an effective dynamic seal between the motor-driven moving parts and the fixed housing, resulting in generally poor waterproof performance. Utility Model Content

[0031] In the field of outdoor security monitoring, cameras need to have good waterproof performance to cope with complex weather conditions. Currently, conventional outdoor cameras are mostly installed using universal ball joints, a structure that allows users to manually adjust the camera's monitoring angle during deployment. However, this solution only supports static adjustment; once installed, the camera cannot be dynamically adjusted according to real-time monitoring needs. To achieve dynamic monitoring capabilities, some solutions introduce motor-driven mechanisms. However, in practical applications, it is difficult to achieve an effective dynamic seal between the motor-driven moving parts and the fixed housing, resulting in generally poor waterproof performance.

[0032] This application provides a camera to solve the problem that existing cameras cannot simultaneously meet the requirements of dynamic rotation adjustment and waterproofing. The following will be discussed in conjunction with the accompanying drawings. Figures 1-7 Please provide an explanation.

[0033] The camera provided in this application embodiment is referenced from... Figure 1 and Figure 2As shown, the device includes a mounting base 100, a housing 200, a drive unit 300, and an elastic sealing plug 400. The mounting base 100 includes a first bracket 110. The housing 200 is used to mount the camera module. The drive unit 300 is disposed in the housing 200. The output shaft 310 of the drive unit 300 is connected to the first bracket 110. The elastic sealing plug 400 is installed in the housing 200. The elastic sealing plug 400 is provided with an annular first sealing rib 410. The elastic sealing plug 400 is sleeved on the output shaft 310, and the first sealing rib 410 abuts against the outer periphery of the output shaft 310.

[0034] In this embodiment, the basic frame of the camera consists of a mounting base 100 and a housing 200. The mounting base 100 is used to fix the entire camera to a wall, pole, or other support, and a first bracket 110 is provided on it as a rotating connection base. The housing 200 serves as the main body of the camera, and its interior is used to house and protect the core camera module and related electronic components.

[0035] To enable real-time angle adjustment of the camera, a drive unit 300 (which can be a stepper motor, a DC geared motor, or other drive components) is fixedly mounted inside the housing 200. The power output of the drive unit 300 extends to the outside of the housing 200 via an output shaft 310, the end of which is mechanically connected to a first bracket 110 on the mounting base 100. When the drive unit 300 is working, it can drive the entire housing 200, along with the internal camera module, to tilt or rotate around the axis of the output shaft 310, thereby achieving dynamic adjustment of the monitoring angle.

[0036] The elastic sealing plug 400 is made of silicone, rubber, or other polymer materials with good elasticity. The elastic sealing plug 400 is securely mounted on the housing 200, located where the output shaft 310 protrudes. The elastic sealing plug 400 has a through hole in its center, allowing it to fit tightly onto the output shaft 310 of the drive device 300. More importantly, on the side of the elastic sealing plug 400 facing the interior of the housing 200, one or more annular first sealing ribs 410 are integrally formed. When the elastic sealing plug 400 is in place, these first sealing ribs 410, due to their elastic deformation, form a continuous, uniform, and tight contact with the outer circumferential surface of the output shaft 310.

[0037] The annular first sealing rib 410, utilizing its elasticity, tightly embraces the continuously rotating output shaft 310, forming a waterproof barrier. Whether the output shaft 310 is stationary or rotating, the first sealing rib 410 effectively prevents external rainwater, moisture, dust, and other impurities from intruding into the housing 200 through the rotational gap, thus providing continuous and stable protection for the precision camera module and drive unit 300, meeting IPX5 waterproof requirements. Unlike traditional rigid interference fit seals, the elastic sealing plug 400 and the first sealing rib 410 used in this embodiment have an elastic contact with the output shaft 310. This contact method ensures sealing while reducing frictional torque to a low level. The drive unit 300 does not need to provide a large amount of additional torque to overcome sealing friction, thereby reducing energy consumption, motor load, and heat generation. This makes the camera rotation smoother and more stable, with a faster response speed, perfectly balancing the dual requirements of waterproofing and rotation.

[0038] In one alternative implementation, refer to Figure 2 As shown, there are multiple first sealing ribs 410, such as two or three, and the multiple first sealing ribs 410 are spaced apart along the axial direction of the elastic sealing plug 400.

[0039] In this embodiment, to further enhance the reliability of the seal, the elastic sealing plug 400 is provided with multiple first sealing ribs 410. These first sealing ribs 410 are all annular and are arranged side by side with a certain distance between them along the axial direction of the elastic sealing plug 400, that is, along the length direction of the output shaft 310.

[0040] Specifically, when the elastic sealing plug 400 is fitted onto the output shaft 310, these multiple first sealing ribs 410 will form a series of independent, parallel sealing rings on the outer circumferential surface of the output shaft 310. Each first sealing rib 410 utilizes its own elasticity to independently form a tight contact seal with the outer circumferential surface of the output shaft 310, thereby significantly improving the reliability and service life of the seal.

[0041] In one optional embodiment, the first sealing rib 410 on the outer side of the elastic sealing plug 400 has a first interference fit with the output shaft 310, and the first sealing rib 410 on the inner side of the elastic sealing plug 400 has a second interference fit with the output shaft 310, and the first interference fit is greater than the second interference fit.

[0042] In this embodiment, the multiple first sealing ribs 410 on the elastic sealing plug 400 adopt an asymmetrical interference fit design. Specifically, the sealing plug is divided axially into an outer side (i.e., the side closer to the external environment) and an inner side (i.e., the side closer to the interior of the housing 200).

[0043] The first sealing rib 410 located on the outer side has a first interference fit with the outer circumferential surface of the output shaft 310. This interference fit is relatively large, meaning that the first sealing rib 410 will be compressed more tightly after installation, thereby generating a greater radial clamping force on the output shaft 310. In contrast, the first sealing rib 410 located on the inner side has a second interference fit with the outer circumferential surface of the output shaft 310. The second interference fit is set smaller than the first interference fit, making the clamping force of the inner first sealing rib 410 on the output shaft 310 relatively smaller and gentler. While ensuring sealing and waterproof performance, it can minimize friction and make the rotation process of the elastic sealing plug 400 relative to the output shaft 310 smoother.

[0044] For example, when there are two first sealing ribs 410, the interference between the inner first sealing rib 410 and the output shaft 310 is 0.05 mm. The interference between the outer first sealing rib 410 and the output shaft 310 is 0.15 mm.

[0045] Furthermore, lubricating oil can be applied to the entire outer circumference of the output shaft 310 to further reduce rotational friction.

[0046] In one alternative implementation, refer to Figure 2 As shown, the elastic sealing plug 400 also includes an end plate 420, and the end plate 420 is provided with a second sealing rib 421. When the elastic sealing plug 400 is installed on the housing 200, the second sealing rib 421 abuts against the housing 200.

[0047] In this embodiment, the end plate 420 is a plate-like structure extending radially outward from the main body of the elastic sealing plug 400. At least one ring of second sealing ribs 421 is integrally formed on the surface of the end plate 420. These second sealing ribs 421 are raised annular structures, with their protrusion direction facing the housing 200. When the elastic sealing plug 400 is assembled onto the housing 200, the end plate 420 will achieve a tight fit with a corresponding mounting plane on the housing 200 (such as the outer wall of the housing 200). Through fasteners (such as screws) or the structural compression of the housing 200 itself, the second sealing ribs 421 on the end plate 420 will undergo elastic deformation, thereby forming a strong static seal with the mounting plane of the housing 200. This enhances structural rigidity and installation stability, and optimizes static sealing performance.

[0048] In one optional implementation, combined with Figure 2 and Figure 4As shown, the first bracket 110 is provided with a first mounting groove 111. The camera also includes a transmission rod 112 and a first hanging ear 120. One end of the transmission rod 112 is connected to the output shaft 310, and the other end is fixedly connected to the first bracket 110. The first hanging ear 120 is sleeved in the first mounting groove 111, and the first hanging ear 120 is fixedly connected to the housing 200. The first hanging ear 120 abuts against the end plate 420 of the elastic sealing plug 400.

[0049] In this embodiment, a transmission rod 112 is installed at the end of the output shaft 310, and the transmission rod 112 can be locked onto the first bracket 110 by two screws, thereby realizing the rotational power transmission of the drive device 300.

[0050] The first lug 120 is roughly in the form of a sleeve or bearing seat. It is movably fitted onto the first mounting groove 111 of the transmission rod 112 and can rotate freely around the transmission rod 112. Simultaneously, the first lug 120 is fixedly connected to the camera housing 200 by bolts, welding, or other methods, forming a single unit. During assembly, the elastic sealing plug 400 is placed between the housing 200 and the first lug 120, with one side of its end plate 420 tightly against the end face of the first lug 120. After the entire assembly is hooked into the first mounting groove 111 of the first bracket 110 via the first lug 120, tightening the nuts or other fasteners at the end of the transmission rod 112 sequentially and firmly presses the first bracket 110, the first lug 120, the end plate 420 of the elastic sealing plug 400, and the housing 200 together. This ensures that the second sealing rib 421 tightly abuts against the housing 200, achieving a seal and significantly enhancing the stability and durability of the seal.

[0051] In an optional embodiment, the interference fit between the second sealing rib 421 and the housing 200 is greater than the interference fit between the first sealing rib 410 and the output shaft 310.

[0052] In this embodiment, the second sealing rib 421 located on the end plate 420 of the elastic sealing plug 400 has a relatively large interference fit with the mounting plane of the housing 200, for example, 0.25 mm. When the end plate 420 is pressed against the housing 200, the second sealing rib 421 undergoes significant elastic compression, thereby generating strong sealing pressure. Since the elastic sealing plug 400 rotates with the housing 200 during rotation, and there is no relative movement between them, the interference fit at this location can be set larger to improve sealing performance. However, the output shaft 310 and the elastic sealing plug 400 will move relative to each other, so the interference fit at the first sealing rib 410 is designed to be smaller to reduce frictional resistance, perfectly matching the different sealing requirements of the static sealing area and the dynamic sealing area.

[0053] In one alternative implementation, refer to Figure 1As shown, the mounting base 100 also includes a second bracket 130, which is located on opposite sides of the mounting base 100, and the housing 200 is rotatably connected between the first bracket 110 and the second bracket 130.

[0054] In this embodiment, a first bracket 110 and a second bracket 130 are respectively provided on opposite sides of the mounting base 100 to form a stable support frame. The two sides of the housing 200 are rotatably connected to the first bracket 110 and the second bracket 130 respectively. The driving device 300 is located on the side closer to the first bracket 110 to realize power transmission, and the second bracket 130 is rotatably connected only by a rotating joint. When the driving device 300 is working, it will drive the housing 200 to rotate synchronously around the first bracket 110 and the second bracket 130, which greatly improves the structural rigidity and deformation resistance of the camera, and enhances the overall vibration resistance and impact resistance of the camera.

[0055] In one alternative implementation, refer to Figure 3 and Figure 5 As shown, the second bracket 130 has a second mounting groove 131. The camera also includes: a second hook 140, which is sleeved in the second mounting groove 131. The second hook 140 is fixedly connected to the housing 200, and the second hook 140 has a first sealing groove 141 along the circumference; and a first sealing ring 150, which is installed in the first sealing groove 141 and abuts against the groove wall of the first sealing groove 141 and the groove wall of the second mounting groove 131.

[0056] In this embodiment, to achieve all-around protection for the camera, the second bracket 130 at the non-drive end also employs a sealing structure. The second hook 140 is fixedly connected to the housing 200, and the second hook 140 is fitted into the second mounting groove 131 of the second bracket 130, allowing the second hook 140 and the housing 200 to rotate relative to the second bracket 130. The first sealing ring 150 can be an O-ring. When the second hook 140 is fitted into the second mounting groove 131 of the second bracket 130, the first sealing ring 150 is compressed, and its outer surface tightly abuts against the inner wall (groove wall) of the second mounting groove 131. At the same time, the inner surface and two sides of the first sealing ring 150 are also tightly fitted against the groove wall of the first sealing groove 141. Thus, a reliable dynamic sealing structure is formed between the relative rotating surfaces of the second hook 140 and the second bracket 130, improving the sealing and waterproof performance at the connection between the second bracket 130 and the housing 200.

[0057] For example, the second loop 140 can be made of self-lubricating POM material, and the surface of the first sealing ring 150 needs to be coated with lubricating oil to reduce friction. Considering a lifespan of 100,000 rotations, the first sealing ring 150 needs to be made of wear-resistant HNBR material, not silicone. After 100,000 rotations, and while also meeting IPX5 waterproof requirements, the compression ratio of the first sealing ring 150 needs to be 15%.

[0058] In an optional embodiment, the camera further includes a waterproof adhesive layer 160, one end of which abuts against the end face of the second hook 140, and the other end of which abuts against the end face of the housing 200.

[0059] In this embodiment, the waterproof adhesive layer 160 is a material with strong adhesion and excellent waterproof performance. Its properties can be annular or sheet-like, with moderate thickness, which can fill gaps and maintain its shape under pressure.

[0060] During assembly, the waterproof adhesive layer 160 is placed between the contact surfaces of the second hook 140 and the housing 200. Specifically, one end face of the waterproof adhesive layer 160 is tightly fitted and bonded to the end face of the second hook 140 facing the housing 200; while its other end face is tightly fitted and bonded to the corresponding mounting end face on the housing 200. When the second hook 140 is fixed to the housing 200 by bolts or other means, this waterproof adhesive layer 160 is firmly sandwiched in the middle, bonding the second hook 140 to the housing 200, while simultaneously achieving a static waterproof seal between the second hook 140 and the housing 200.

[0061] In one optional implementation, combined with Figure 6 and Figure 7 As shown, the housing 200 includes a front housing 210, a rear housing 220, and a second sealing ring 230. The front housing 210 has a second sealing groove 211 along its circumferential side. The rear housing 220 is installed on the front housing 210. The second sealing ring 230 is disposed in the second sealing groove 211 and abuts against the groove wall of the second sealing groove 211 and the inner wall of the rear housing 220.

[0062] In this embodiment, the front shell 210 is the main body of the housing 200 and can be used to install the lens module of the camera. A second sealing groove 211 is formed along the entire circumference (i.e., around the perimeter) at the opening edge of the front shell 210. The rear shell 220 is a cover-like component used to close the opening of the front shell 210, thereby enclosing all electronic components such as the internal camera module, drive device 300, and circuit board.

[0063] The second sealing ring 230 is precisely placed within the second sealing groove 211 of the front housing 210. When the rear housing 220 is installed onto the front housing 210 and secured with screws, clips, or other means, the inner wall of the rear housing 220 presses against the second sealing ring 230. At this time, the second sealing ring 230 undergoes elastic deformation, with its inner ring tightly abutting against the groove wall of the second sealing groove 211 and its outer ring tightly abutting against the inner wall of the rear housing 220. This forms a continuous and reliable static sealing barrier between the mating surfaces of the front housing 210 and the rear housing 220, further improving the camera's sealing and waterproof performance.

[0064] The camera provided in this application embodiment includes a mounting base 100, a housing 200, a driving device 300, and an elastic sealing plug 400. It is mounted on a first bracket 110. The housing 200 is used to mount the camera module. The driving device 300 is disposed on the housing 200. The output shaft 310 of the driving device 300 is connected to the first bracket 110. The elastic sealing plug 400 is mounted on the housing 200. The elastic sealing plug 400 is provided with an annular first sealing rib 410. The elastic sealing plug 400 is sleeved on the output shaft 310. The first sealing rib 410 abuts against the outer periphery of the output shaft 310. By fitting an elastic sealing plug 400 with an annular first sealing rib 410 onto the output shaft 310 of the drive device 300, and utilizing the elastic contact between the first sealing rib 410 and the outer circumferential surface of the output shaft 310, a reliable dynamic waterproof barrier is formed. This barrier can tightly fit the output shaft 310 with sufficient preload, effectively preventing moisture and dust from entering the housing 200 and ensuring a high level of waterproof performance. At the same time, its elastic contact avoids the huge friction caused by traditional rigid interference fits, thereby minimizing rotational resistance. Therefore, this camera can achieve smooth and reliable real-time angle adjustment without sacrificing motor drive performance, thus meeting the dual requirements of dynamic waterproofing and smooth rotation.
