Description

Technical Field

[0001] This invention relates to the field of camera-related technology, specifically to a camera that is easy to assemble. Background Technology

[0002] Cameras are the front-end component of a surveillance system, serving as the "eyes" of the entire system. Cameras generally have basic functions such as video recording / transmission and still image capture. They acquire images through a lens, and then the camera's internal photosensitive components and control components process the images and convert them into digital signals that a computer can recognize. These signals are then input to a computer via a parallel port or USB connection, where software reconstructs the image.

[0003] In existing technology, cameras are mainly composed of a camera module, a control module, and a housing. The housing is used to protect the internal structures such as the camera module and control module. Therefore, the sealing performance of the housing is particularly important for protecting the performance and lifespan of the internal components. Thus, sealing rings are often used to ensure the waterproofness of the camera.

[0004] However, the following problems still exist in actual assembly: the housing is mostly composed of a front cover, a base shell, and a rear cover, and the sealing ring is set between the front cover and the base shell, as well as between the rear cover and the base shell. In the existing technology, the front cover, base shell, and rear cover are fixed by bolts. It is difficult to control the tightening force during assembly. If the tightening force is too large, it will increase the pressure of the front cover and the rear cover on the sealing ring, which can easily damage the sealing ring. If the sealing ring and the sealing surface cannot fit tightly, the sealing effect will be poor. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a camera that is easy to assemble.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] The present invention provides a camera that is easy to assemble, comprising a housing, which is composed of a front shell, a base shell and a rear shell. The base shell is provided with a support bracket. The front shell and the rear shell are both composed of a support cylinder and a connecting cylinder screwed to the base shell. The connecting cylinder is sleeved on the outside of the support cylinder, and an installation groove is formed between the outer wall of the support cylinder and the inner wall of the connecting cylinder.

[0008] A camera module located on one side of the support bracket and a main control board located on the other side of the support bracket;

[0009] A sealing airbag is installed in the mounting groove;

[0010] An annular encapsulation body fitted onto the outside of the support cylinder;

[0011] An air storage component is disposed within an annular encapsulation body and can inflate a sealed airbag. The air storage component is an airbag or an elastic air storage element, and an air storage cavity is formed between the elastic air storage element and the connecting cylinder.

[0012] A compression component located on one side of the gas storage component compresses the gas storage component, causing the gas to flow into the sealing airbag.

[0013] As a preferred technical solution of the present invention, the extrusion assembly includes an annular extrusion plate, a transmission rod, and an operating cylinder. The annular extrusion plate is slidably disposed inside the annular package body. The transmission rod is mounted on the annular extrusion plate. A return spring is sleeved on the transmission rod. The two ends of the return spring are respectively connected to the annular package body and the annular extrusion plate.

[0014] An annular mating platform is provided on the inner wall of one end of the operating cylinder. An annular mating groove that mates with the transmission rod is provided on the annular mating platform. Several mating guide posts are also installed on the inner wall of the annular mating platform.

[0015] As a preferred embodiment of the present invention, the elastic gas storage component is a ring structure, comprising a middle connecting part and two fixing parts. The two fixing parts are respectively connected to the annular encapsulation body and the support cylinder. The middle connecting part is connected to the annular extrusion plate. Deformation parts are provided on both the inner and outer sides of the middle connecting part. The two ends of the deformation parts are respectively connected to the middle connecting part and the fixing parts.

[0016] As a preferred embodiment of the present invention, the airbag is connected to an inflation port, and one side of the airbag is provided with annular sealing protrusions from the inside to the outside.

[0017] As a preferred embodiment of the present invention, the connecting cylinder is provided with a vent hole, which is used to communicate with the air storage bag or with the inflation interface.

[0018] As a preferred embodiment of the present invention, the annular package has a through hole that slides with the transmission rod, and the annular package is connected to the support cylinder and the connecting cylinder.

[0019] As a preferred embodiment of the present invention, the support cylinder is provided with a plurality of mating grooves that can slide with the mating guide post. The mating grooves consist of two locking grooves for locking the mating guide post and a moving groove for connecting the locking grooves.

[0020] As a preferred embodiment of the present invention, the camera module includes a support bracket, in which a zoom mechanism and a lens are installed, and the moving end of the zoom mechanism is detachably connected to the lens.

[0021] As a preferred embodiment of the present invention, the support bracket has several support columns on both sides, and the support columns are detachably connected to the support bracket or the main control board by bolts. The support bracket also has several positioning rods on one side, and the main control board has several positioning notches that match the positioning rods.

[0022] As a preferred embodiment of the present invention, the front shell has a reserved hole at the closed end, and a protective lens is provided in the reserved hole.

[0023] The beneficial effects of this invention are:

[0024] 1. This type of easily assembled camera uses threaded connections to assemble the front shell, rear shell, and base shell together. By moving the operating cylinder, the transmission rod can drive the annular extrusion plate close to the gas storage component. The annular extrusion plate squeezes the gas storage component, causing gas to flow into the sealing airbag, which expands and fits tightly against the sealing surface, achieving a seal. This effectively avoids damage to the sealing airbag caused by the front and rear shells during assembly. The gas storage component inflates the sealing airbag, causing it to expand and fit tightly against the sealing surface, ensuring a tight seal. Furthermore, the base shell is connected to the front and rear shells using a threaded connection, which not only facilitates assembly but also eliminates the need for additional tools.

[0025] 2. This type of easily assembled camera uses an air storage component, which is either an air bladder or an elastic air storage element. When the air bladder is compressed, the gas inside it enters the sealed air bladder, causing it to expand. By moving the intermediate connecting part on the elastic air storage element, the deformation part deforms, reducing the volume of the air storage chamber. The gas inside the chamber then enters the sealed air bladder, causing it to expand. Therefore, manufacturers can flexibly choose between an air bladder or an elastic air storage element as the air storage component according to actual needs, which helps meet different user requirements.

[0026] 3. This type of camera, which is easy to assemble, has a compression assembly consisting of an annular compression plate, a transmission rod, a return spring, and an operating cylinder. By moving the annular compression plate, the gas storage bag can be compressed to inflate the sealing gas bag. The middle connecting part of the elastic gas storage component needs to be connected to the annular compression plate. By moving the annular compression plate, the middle connecting part can be driven to deform the deformation part, thus inflating the sealing gas bag. Therefore, the compression assembly can be well adapted to the gas storage bag and the elastic gas storage component, and has high versatility.

[0027] 4. This type of camera, which is easy to assemble, can limit the transmission rod through the set annular mating groove, and the presence of the annular mating groove allows the operating cylinder to rotate smoothly around the support cylinder. Attached Figure Description

Detailed Implementation

[0043] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0044] Example: Figures 1-4 and Figures 6-8 As shown, the present invention provides a camera that is easy to assemble, comprising a housing consisting of a front shell 1, a base shell 2, and a rear shell 3. The base shell 2 is provided with a support bracket 21. Both the front shell 1 and the rear shell 3 are composed of a support cylinder 12 and a connecting cylinder 13 screwed to the base shell 2. The connecting cylinder 13 is sleeved on the outside of the support cylinder 12, and an installation groove 14 is formed between the outer wall of the support cylinder 12 and the inner wall of the connecting cylinder 13.

[0045] A camera module 5 is located on one side of the support bracket 21, and a main control board 6 is located on the other side of the support bracket 21;

[0046] A sealing airbag 10 is installed in the mounting groove 14;

[0047] An annular encapsulation body 4 is fitted over the support cylinder 12;

[0048] An air storage component 7 is disposed within the annular encapsulation body 4 and can inflate the sealing airbag 10. The air storage component 7 is an air storage airbag or an elastic air storage component. An air storage cavity 8 is formed between the elastic air storage component and the connecting cylinder 13.

[0049] The extrusion assembly 9, located on one side of the gas storage assembly 7, extrudes the gas storage assembly 7 to make the gas flow to the sealing airbag 10.

[0050] In this embodiment, the gas storage bag can be fixed to the connecting cylinder 13 by adhesive bonding, or other connection methods such as snap-fit ​​connection can be used. The specific installation method of the gas storage bag is not limited here, so it is not marked in the figure. In addition, the air outlet of the gas storage bag can be connected to the vent 131. Therefore, after the gas storage bag is compressed, the gas inside the gas storage bag can enter the sealing bag 10 through the vent 131, causing the sealing bag 10 to expand.

[0051] In this embodiment, a wire hole is provided at the closed end of the rear shell 3, through which the power cord can pass. In order to ensure waterproofing, a waterproof seal is required at the wire hole after the power cord passes through.

[0052] In addition, an anti-slip ring is also fitted on the outside of the support cylinder 12. The anti-slip ring can be connected to the support cylinder 12 by a snap-fit ​​method and is detachable. The anti-slip ring can limit the operation cylinder 94 and effectively prevent the operation cylinder 94 from detaching from the support cylinder 12.

[0053] Among them, such as Figure 8 and Figures 10-12 As shown, the extrusion assembly 9 includes an annular extrusion plate 91, a transmission rod 92, and an operating cylinder 94. The annular extrusion plate 91 is slidably disposed inside the annular encapsulation body 4. The transmission rod 92 is mounted on the annular extrusion plate 91. A return spring 93 is sleeved on the transmission rod 92. The two ends of the return spring 93 are respectively connected to the annular encapsulation body 4 and the annular extrusion plate 91.

[0054] An annular mating platform 941 is provided on the inner wall of one end of the operating cylinder 94. An annular mating groove 942 that mates with the transmission rod 92 is provided on the annular mating platform 941. Several mating guide posts 943 are also installed on the inner wall of the annular mating platform 941.

[0055] By rotating the operating cylinder 94, the mating guide post 943 moves from the locking groove 121 into the moving groove. Then, the operating cylinder 94 is pushed towards the connecting cylinder 13. At this time, the mating guide post 943 moves from one end of the moving groove to the other. The operating cylinder 94 pushes the transmission rod 92, causing the return spring 93 to be in a stretched state. Simultaneously, the transmission rod 92 drives the annular extrusion plate 91 towards the gas storage assembly 7. The annular extrusion plate 91 extrudes the gas storage assembly 7, causing the gas to flow into the sealing airbag 10. Finally, the sealing airbag 10 expands and tightly seals against the sealing surface. The system is sealed first, and then the operating cylinder 94 is rotated to move the mating guide post 943 from the moving groove to another locking groove 121. The mating guide post 943 is locked by the locking groove 121, thus fixing the operating cylinder 94. This can effectively prevent the front shell 1 and the rear shell 3 from damaging the sealing airbag 10 during assembly. The sealing airbag 10 is inflated by the air storage component 7, so that the sealing airbag 10 expands and fits tightly against the sealing surface to ensure the sealing performance. The base shell 2 is connected to the front shell 1 and the rear shell 3 by a threaded connection, which not only facilitates assembly but also eliminates the need for additional tools.

[0056] During the process of moving the operating cylinder 94 back to its original position, the elastic force of the return spring 93 drives the transmission rod 92, which in turn drives the annular extrusion plate 91 back to its original position, so that the gas storage component 7 is no longer compressed. At this time, the gas in the sealing airbag 10 flows to the gas storage component 7, the sealing airbag 10 retracts to its original shape, separates from the sealing surface, and releases the sealing state. Then the front shell 1 and the rear shell 3 can be removed from the base shell 2. The extrusion component 9 can be used for gas storage airbags and elastic gas storage components, so it has high versatility.

[0057] In this embodiment, the transmission rod 92 can be limited by the annular groove 942, and the presence of the annular groove 942 allows the operating cylinder 94 to rotate smoothly around the support cylinder 12.

[0058] It should be noted that, in addition to the connection structure formed by the guide post 943 and the groove provided in this embodiment, the operating cylinder 94 and the support cylinder 12 can also be connected by threads. By rotating the operating cylinder 94, the operating cylinder 94 can be rotated and moved, thereby allowing the transmission rod 92 to slide in the through hole.

[0059] Among them, such as Figure 8 , Figure 10 and Figure 11As shown, the elastic gas storage component has a ring-shaped structure. The elastic gas storage component includes a middle connecting part 73 and two fixing parts 72. The two fixing parts 72 are respectively connected to the annular encapsulation body 4 and the support cylinder 12. The middle connecting part 73 is connected to the annular extrusion plate 91. Deformation parts 71 are provided on both the inner and outer sides of the middle connecting part 73. The two ends of the deformation parts 71 are respectively connected to the middle connecting part 73 and the fixing parts 72. The elastic gas storage component can be made of metal materials or elastic materials such as rubber and silicone rubber. Among them, compared with the elastic gas storage component made of rubber and silicone rubber, the elastic gas storage component made of metal materials has a longer service life in theory.

[0060] When the operating cylinder 94 is pushed toward the connecting cylinder 13, the annular extrusion plate 91 will drive the intermediate connecting part 73 to move into the gas storage chamber 8. The moving intermediate connecting part 73 causes the deformation part 71 to deform. With the help of the deformation part 71, the volume of the gas storage chamber 8 becomes smaller, and the gas in the gas storage chamber 8 will enter the sealing airbag 10, causing the sealing airbag 10 to expand and fit tightly against the sealing surface to achieve a seal. When the operating cylinder 94 is pushed away from the connecting cylinder 13, the annular extrusion plate 91 will drive the intermediate connecting part 73 back to its original position, causing the elastic gas storage component to return to its original shape. At this time, the gas in the sealing airbag 10 flows into the gas storage chamber 8, and the sealing airbag 10 also detaches from the sealing surface, releasing the sealing state.

[0061] In this embodiment, in order to inflate the air storage chamber 8, an inflation tube can be provided on the fixing part 72 located on the outside. The inflation tube needs to pass through the operating cylinder 94. In addition, when the sealing airbag 10 is not installed, the air storage chamber 8 can also be inflated using the vent hole 131.

[0062] Among them, such as Figure 13 As shown, the sealing airbag 10 is connected to an inflation port 102. An annular sealing protrusion 101 is provided on one side of the sealing airbag 10 from the inside to the outside. The annular sealing protrusion 101 is integrally formed with the sealing airbag 10 and is made of the same material. The annular sealing protrusion 101 can be inserted into the gap between the connecting cylinder 13 and the base shell 2 and fits against the sealing surface, which is beneficial to improving the sealing performance.

[0063] Among them, such as Figure 5 , Figure 6 and Figure 9 As shown, the connecting cylinder 13 is provided with a vent hole 131. The vent hole 131 is used to communicate with the air storage bladder or the inflation interface 102. The vent hole 131 enables the air storage bladder and the air storage chamber 8 to communicate with the sealing bladder 10. Therefore, when the gas in the air storage bladder and the air storage chamber 8 does not flow to the sealing bladder 10, there is also a suitable amount of gas in the sealing bladder 10, so that the sealing bladder 10 and the air storage bladder and the air storage chamber 8 maintain the same air pressure.

[0064] Among them, such as Figure 8 and Figure 10 As shown, the annular encapsulation body 4 has a through hole that slides with the transmission rod 92. The annular encapsulation body 4 is connected to the support cylinder 12 and the connecting cylinder 13. The through hole is used to install the transmission rod 92. The annular encapsulation body 4 provides support for the transmission rod 92. The cross-sectional shape of the annular encapsulation body 4 is L-shaped. The installation space formed between the annular encapsulation body 4, the support cylinder 12, and the connecting cylinder 13 is used to install the gas storage component 7 and also provides space for the movement of the annular extrusion plate 91.

[0065] Among them, such as Figure 5 and Figure 6 As shown, the support cylinder 12 has several mating grooves that can slide with the mating guide post 943. The mating groove consists of two locking grooves 121 for locking the mating guide post 943 and a moving groove for connecting the locking grooves 121. The moving groove allows the operating cylinder 94 to move along the support cylinder 12; the locking groove 121 can lock the mating guide post 943 and fix the operating cylinder 94.

[0066] Among them, such as Figures 2-4 As shown, the camera module 5 includes a support bracket 51, in which a zoom mechanism and a lens 52 are installed. The moving end of the zoom mechanism is detachably connected to the lens 52. The support bracket 51 is used to support the zoom mechanism and the lens 52. The zoom mechanism can be a voice coil motor or other implementation methods. The specific structure of the zoom mechanism is not limited here. The focal length of the lens 52 can be changed by using the zoom mechanism.

[0067] Among them, such as Figure 1 and Figure 2 As shown, the support bracket 21 has several support columns 22 on both sides. The support columns 22 are detachably connected to the support bracket 51 or the main control board 6 by bolts. The support bracket 21 also has several positioning rods 23 on one side, and the main control board 6 has several positioning notches that match the positioning rods 23. The main control board 6 is positioned by the positioning rods 23 and the positioning notches, thereby improving the assembly speed.

[0068] It should be noted that when installing the camera module 5, the positioning structure consisting of the positioning rod 23 and the positioning notch can also be used to position the camera module 5 to further improve the assembly speed. Here, the shape and specific installation position of the positioning rod 23 and the positioning notch used by the support bracket 51 will not be limited, and therefore are not marked in the attached drawings.

[0069] Among them, such as Figure 1 and Figure 2As shown, the front shell 1 has a reserved hole at the closed end, and a protective lens 11 is provided in the reserved hole. The protective lens 11 can not block the lens 52, which is conducive to shooting the picture through the lens 52. The protective lens 11 also plays a role in waterproofing and dustproofing.

[0070] During operation, the camera module 5 and the main control board 6 are first fixed on both sides of the support bracket 21. After the front shell 1 and the rear shell 3 are installed at both ends of the base shell 2, the operating cylinder 94 is rotated to move the mating guide post 943 from the locking groove 121 into the moving groove. Then, the operating cylinder 94 is pushed towards the connecting cylinder 13. At this time, the mating guide post 943 moves from one end of the moving groove to the other end. The operating cylinder 94 pushes the transmission rod 92, so that the return spring 93 is in a stretched state. At the same time, the transmission rod 92 drives the annular extrusion plate 91 to approach the gas storage component 7. The annular extrusion plate 91 extrudes the gas storage component 7, so that the gas flows into the sealing airbag 10. Finally, the sealing airbag 10 expands and fits tightly with the sealing surface to achieve a seal. Then, the operating cylinder 94 is rotated again to move the mating guide post 943 from the moving groove to another locking groove 121. The locking groove 121 locks the mating guide post 943, thus completing the fixation of the operating cylinder 94 and completing the seal between the base shell 2 and the front shell 1 and the rear shell 3.

[0071] When disassembling the camera, during the process of moving the operating cylinder 94 back to its original position, the elastic force of the reset spring 93 is used to drive the transmission rod 92. The transmission rod 92 drives the annular extrusion plate 91 back to its original position, so that the gas storage component 7 is no longer compressed. At this time, the gas in the sealing airbag 10 flows to the gas storage component 7, the sealing airbag 10 retracts to restore its original shape, separates from the sealing surface, and releases the sealing state. Then the front shell 1 and the rear shell 3 can be removed from the base shell 2.

[0072] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
