Description

Technical Field

[0001] The present invention relates to the technical field of cameras, and in particular to a camera. Background Art

[0002] At present, the application of cameras in underwater environments is becoming more and more common. In order to facilitate disassembly and assembly, the shells of most cameras are mostly composed of spliced structures. However, since the camera is subject to water pressure in water, when there is a pressure difference between the inside and outside of the camera, the shell will be compressed and deformed toward the side with lower pressure. Since the force-bearing area or shape of the components spliced to form the shell are different, the deformation amount of each component when under pressure may be different, resulting in gaps, affecting the sealing between the two connected components.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] The present invention provides a camera 100 .

[0040] Please refer to Figures 1 to 3 In some embodiments of the present application, the camera 100 includes:

[0041] The housing 110 and the lens assembly 30 are provided in the mounting cavity of the housing 110 and are disposed toward the window 40 of the housing 110. The housing 110 includes:

[0042] The front shell 11 is provided with a viewing window 40;

[0043] The rear shell 13 and the front shell 11 cover each other to enclose a mounting cavity. The end surface of the front shell 11 facing the rear shell 13 is provided with one of the plug-in portion 111 and the plug-in slot 131. The end surface of the rear shell 13 facing the front shell 11 is provided with the other of the plug-in portion 111 and the plug-in slot 131. The plug-in portion 111 and the plug-in slot 131 are both arranged around the circumference of the mounting cavity, and the plug-in portion 111 is inserted into the plug-in slot 131.

[0044] The seal 15 includes a first sealing portion 151 and a second sealing portion 153. The first sealing portion 151 is sandwiched between at least one of the two side walls 1332 of the insertion groove 131 and the insertion portion 111. The second sealing portion 153 is sandwiched between the groove bottom wall 1331 of the insertion groove 131 and the insertion portion 111.

[0045] A glue potting portion is provided on the outer side of the connection position between the front shell 11 and the rear shell 13 . The glue potting portion is arranged around the circumference of the installation cavity, and a glue potting cavity 139 is formed in the glue potting portion.

[0046] The camera 100 proposed in the present application is used for image acquisition, and includes a shell 110 as a supporting base and a lens assembly 30 arranged in the shell 110. It is defined that the camera 100 has a front-to-back direction. The shell 110 includes a front shell 11 and a rear shell 13 covering each other. The front shell 11 of the camera 100 is set with the end face facing away from the rear shell 13 toward the position to be observed, and is provided with a window 40. Only the lens window 40 can be set. In some embodiments, the fill light window 40 and the lens window 40 can also be set at the same time, so that the fill light 90 in the shell 110 is set toward the fill light window 40, and the lens assembly 30 is set toward the lens window 40, so that the lens assembly 30 can collect image information of the position to be observed through the lens window 40, and the light emitted by the fill light 90 can be emitted forward through the fill light window 40, thereby increasing the brightness of the position to be observed, so that the image collected by the lens assembly 30 is clearer.

[0047] In addition, the front shell 11 and the rear shell 13 are plugged into each other, and both the front shell 11 and the rear shell 13 are configured as a cylindrical structure with one end open. The open end surface of the front shell 11 is provided with a surrounding plug-in portion 111 or a plug-in groove 131. Correspondingly, a surrounding plug-in groove 131 or a plug-in portion 111 is provided on the open end surface of the rear shell 13, so that the plug-in portion 111 is plugged into the plug-in groove 131. Furthermore, a seal 15 is provided between the front shell 11 and the rear shell 13. The seal 15 includes a first sealing portion 151 and a second sealing portion 153 connected to each other. The first sealing portion 151 is provided between at least one groove side wall 1332 of the plug-in groove 131 and the plug-in portion 111. The setting position of the first sealing portion 151 can be selected and set according to the ambient pressure of the location where the camera 100 is placed and the size of the internal pressure of the camera 100. For example, when the ambient pressure is greater than the camera 100, When the internal pressure is low, the first sealing portion 151 is arranged between the groove side wall 1332 on the outside and the plug-in portion 111. When the ambient pressure is lower than the internal pressure of the camera 100, the first sealing portion 151 is arranged between the groove side wall 1332 on the inside and the plug-in portion 111. Of course, the first sealing portion 151 can be arranged between both groove side walls 1332 and the plug-in portion 111, which is not limited here. The arrangement of the first sealing portion 151 can make up for the problem of insufficient compression of one side of the front shell 11 and the rear shell 13 when the side wall 1332 of the shell 110 is subjected to pressure from the inside to the outside or from the outside to the inside, so as to avoid the gap between the groove side wall 1332 and the plug-in portion 111 causing sealing failure. The arrangement of the second sealing portion 153 can fill the gap between the plug-in portion 111 and the groove bottom wall 1331 when the shell 110 is subjected to pressure in the front and rear directions, so as to achieve a better sealing effect. Furthermore, a glue filling part is provided on the outside of the plug-in part 111 and the plug-in groove 131, and the glue filling part is used to fill the sealant, which can not only enhance the sealing performance, but also play a buffering role, reduce the pressure on the shell 110, reduce the deformation of the front shell 11 and the rear shell 13 at the connection position, and improve the sealing.

[0048] It can be understood that according to the technical solution of the present invention, the shell 110 of the camera 100 is configured as a combined structure of a front shell 11 and a rear shell 13, and the front shell 11 and the rear shell 13 are connected to each other through the plug-in relationship between the plug-in portion 111 and the plug-in slot 131. With this configuration, when the front shell 11 and the rear shell 13 are compressed and deformed, at least one groove side wall 1332 of the plug-in slot 131 will abut against the plug-in portion 111, thereby reducing the gap between the front shell 11 and the rear shell 13; further, a sealing member 15 is provided in the plug-in slot 131, and the sealing member 15 includes a first sealing member 151 and a second sealing member 153. The first sealing member 151 is sandwiched between the groove side wall 1332 of the plug-in slot 131 and the plug-in portion 111. The first sealing member 151 can be pre-sealed according to the relationship between the external pressure of the detection position of the camera 100 and the internal pressure of the camera 100. The part 151 is arranged at a corresponding position. For example, when the external pressure of the target detection position is greater than the internal pressure of the camera 100, the first sealing part 151 is arranged between the groove side wall 1332 located on the outside and the plug-in part 111. In this way, the front shell 11 and the rear shell 13 are subjected to the pressure into the shell 110 to deform inward. At this time, the outward compression can be achieved by the first sealing part 151, thereby compensating for the problem of insufficient inner compression; when the external pressure of the target detection position is less than the internal pressure of the camera 100, the first sealing part 151 is arranged between the groove side wall 1332 located on the inside and the plug-in part 111 to compensate for the problem of insufficient outer compression; of course, the first sealing part 151 can also be arranged between the two groove side walls 1332 of the plug-in groove 131 and the plug-in part 111 to improve the convenience of use and applicability. The second sealing portion 153 is sandwiched between the bottom wall 1331 of the insertion groove 131 and the insertion portion 111 , and can withstand the pressure in the arrangement direction of the front shell 11 and the rear shell 13 , effectively playing a role of water stopping.

[0049] Furthermore, a glue filling part is provided on the outside of the plug-in part 111 and the plug-in groove 131, and the glue filling part is used to fill the sealant, which can not only enhance the sealing performance, but also play a buffering role, reduce the pressure on the shell 110, reduce the deformation of the front shell 11 and the rear shell 13 at the connection position, and improve the sealing.

[0050] Please refer to Figure 3 In some embodiments of the present application, the slot side wall 1332 of the plugging slot 131 is inclined toward the other slot side wall 1332 along the depth direction of the plugging slot 131 .

[0051] In this embodiment, each groove side wall 1332 of the plug-in groove 131 is arranged at an angle and gradually approaches the other groove side wall 1332. In this way, when the shell 110 is simultaneously subjected to the radial pressure of the opening and the front-to-back pressure of the shell 110, the first sealing portion 151 can withstand part of the front-to-back pressure, thereby producing adaptive deformation to compensate for the problem of mismatched compression amount of the front shell 11 and the rear shell 13 in the front-to-back direction, and avoid the gap between the front shell 11 and the rear shell 13 causing sealing failure.

[0052] Please refer to Figure 3 In some embodiments of the present application, a first rib 155 is protruded from the surface of the first sealing portion 151 facing the corresponding groove side wall 1332 . The first rib 155 is arranged around the circumference of the installation cavity and abuts against the groove side wall 1332 .

[0053] In the technical solution of the present application, a first sealing portion 151 of the sealing member 15 is interposed between the slot sidewall 1332 of the insertion slot 131 and the insertion portion 111 to compensate for insufficient compression on the outside or inside when the housing 110 is pressurized, thereby sealing the gap between the slot sidewall 1332 of the insertion slot 131 and the insertion portion 111. In this embodiment, a first rib 155 is provided on the surface of the first sealing portion 151 facing the slot sidewall 1332. The first rib 155 is arranged along the circumference of the housing 110 along with the first sealing portion 151, so that the first rib 155 abuts against the slot sidewall 1332 and generates elastic compression. This arrangement increases the thickness of the first sealing portion 151 at the location of the first rib 155, resulting in greater compression at that location, allowing it to better fit the slot sidewall 1332, thereby sealing the gap between the slot sidewall 1332 and the insertion portion 111 and improving sealing performance.

[0054] Please refer to Figure 3 In some embodiments of the present application, a second rib 157 is protruded from the surface of the second sealing portion 153 facing the groove bottom wall 1331 . The second rib 157 is arranged around the circumference of the installation cavity and abuts against the groove bottom wall 1331 .

[0055] Similarly, the second sealing portion 153 is used to withstand the pressure of the housing 110 in the front-to-back direction and produce corresponding compression deformation to provide a better sealing effect. In this embodiment, a second rib 157 is provided on the surface of the second sealing portion 153 facing the groove bottom wall 1331. This increases the thickness and compression of the second sealing portion 153 at the location where the second rib 157 is provided. Therefore, when the front shell 11 and the rear shell 13 are subjected to front-to-back pressure and the deformation of the front shell 11 and the rear shell 13 is unequal, the second sealing portion 153 can compensate for the insufficient compression, and the second sealing portion 153 is tightly fitted with the plug-in portion 111 and the groove bottom wall 1331 of the plug-in groove 131, thereby improving the sealing performance.

[0056] Please refer to Figure 3 In some embodiments of the present application, a surface of the second sealing portion 153 facing the plug-in portion 111 is provided with an engaging protrusion 159 , and the engaging protrusion 159 is embedded in the plug-in portion 111 .

[0057] In this embodiment, a fitting protrusion 159 is provided on the surface of the second sealing portion 153 facing the plug-in portion 111, and the fitting protrusion 159 is embedded in the plug-in portion 111, so that the sealing member 15 is connected and fixed to the plug-in portion 111, which can improve the position stability of the sealing member 15 and avoid the sealing failure caused by the displacement of the sealing member 15.

[0058] Please refer to Figure 2 In some embodiments of the present application, a glue-containing wall 113 is protruding from the outer wall of the front shell 11. The glue-containing wall 113 is arranged around the circumference of the front shell 11 and extends toward the rear shell 13.

[0059] A sealing wall 133 is protruded from the outer wall of the rear shell 13. The sealing wall 133 is arranged around the circumference of the rear shell 13 and extends toward the front shell 11 to connect with the glue-containing wall 113, thereby enclosing a glue-filling cavity 139 with the glue-containing wall 113, the outer wall of the front shell 11, and the outer wall of the rear shell 13. The sealing wall 133 is provided with a glue-filling port 1333 that communicates with the glue-filling cavity 139.

[0060] The technical solution of the present application is to set a glue filling part on the outside of the plug-in position of the front shell 11 and the rear shell 13, for filling sealant to play a buffering and protective role on the connection position, reduce the external pressure on the connection position, thereby reducing the difference in deformation and compression between the front shell 11 and the rear shell 13 at the connection position, so that the front shell 11 and the rear shell 13 maintain a good sealing effect at the connection position. In this embodiment, the outer wall of the front shell 11 is provided with a glue-containing wall 113, which is spaced apart from the outer wall 1332 of the front shell 11 and extends to one side of the rear shell 13. The outer wall of the rear shell 13 is provided with a sealing wall 133, which is spaced apart from the outer wall 1332 of the rear shell 13 and extends to the front shell 11, so that the sealing wall 133 is connected to the glue-containing wall 113, thereby forming a glue filling cavity 139 set around the connection position between the glue-containing wall 113, the sealing wall 133 and the outer walls of the front shell 11 and the rear shell 13. With this arrangement, the glue pouring portion and the glue pouring cavity 139 can be formed simultaneously when the front shell 11 and the rear shell 13 are assembled. The sealant can then be injected into the glue pouring cavity 139 from the glue pouring port 1333 opened on the sealing wall 133, thereby improving assembly efficiency.

[0061] Please refer to Figure 2 In some embodiments of the present application, the adhesive wall 113 extends to the rear shell 13 .

[0062] It is understandable that the present application requires that the glue filling portion be covered on the outside of the connection position between the front shell 11 and the rear shell 13 to improve the sealing performance of the front shell 11 and the rear shell 13 at the connection position, and the glue filling port 1333 of the glue filling portion is opened on the sealing wall 133 of the rear shell 13. In this embodiment, the glue-containing wall 113 is extended to one side of the rear shell 13 across the connection position between the front shell 11 and the rear shell 13. With such an arrangement, when the end face of the front shell 11 is placed on the bearing surface for glue filling, it can be ensured that the poured glue submerges the connection position between the front shell 11 and the rear shell 13, thereby ensuring that there is a protective layer formed by the sealant on the outside of the connection position between the front shell 11 and the rear shell 13, thereby ensuring that the arrangement of the glue filling portion can play the expected protective and buffering role.

[0063] Please refer to Figure 4 In some embodiments of the present application, the end surface of the glue-containing wall 113 facing the sealing wall 133 is provided with one of the protrusion 115 and the groove 134, and the end surface of the sealing wall 133 facing the glue-containing wall 113 is provided with the other of the protrusion 115 and the groove 134. The protrusion 115 and the groove 134 are both arranged around the circumference of the installation cavity, and the protrusion 115 is inserted into the groove 134.

[0064] It is understandable that the present application requires that the glue potting portion be coated on the outside of the connection position between the front shell 11 and the rear shell 13, so as to improve the sealing performance of the front shell 11 and the rear shell 13 at the connection position through the glue potting sealing structure. In this embodiment, a plug-in structure is provided between the docking position of the glue-containing wall 113 and the sealing wall 133. Such a configuration forms multiple bending paths at the connection position between the glue-containing wall 113 and the sealing wall 133, thereby increasing the difficulty of the sealant overflowing from the connection position between the glue-containing wall 113 and the sealing wall 133, and preventing the sealant from overflowing outward from the connection position between the glue-containing wall 113 and the sealing wall 133.

[0065] Please refer to Figure 9 and Figure 10 In some embodiments of the present application, the sealing wall 133 is provided with an exhaust port 1334 communicating with the glue pouring cavity 139 , and the exhaust port 1334 and the glue pouring port 1333 are spaced apart along the circumference of the installation cavity.

[0066] In the technical solution of the aforementioned embodiment, after the front shell 11 and the rear shell 13 are assembled, they naturally combine outside the connection point to form a glue pouring portion, and the glue pouring port 1333 of the glue pouring portion is opened on the sealing wall of the rear shell 13. As can be understood, to prevent glue leakage, the glue pouring cavity 139 has better sealing performance. In this embodiment, the sealing wall 133 is opened to the vent port 1334 connected to the glue pouring cavity 139. This arrangement allows the air in the glue pouring cavity 139 to be discharged while glue is being poured into the glue pouring cavity 139, preventing the presence of gas in the glue pouring cavity 139 from affecting the glue pouring.

[0067] Please refer to Figure 9 In some embodiments of the present application, the sealing wall 133 includes a bottom wall 1331 and a side wall 1332 connected to each other. The bottom wall 1331 is protruded from the outer wall of the rear shell 13, and the side wall 1332 and the bottom wall 1331 extend toward the side of the front shell 11. The surface of the bottom wall 1331 facing away from the front shell 11 is provided with at least two glue filling ports 1333, and the at least two glue filling ports 1333 are arranged at intervals along the circumference of the installation cavity. The surface of the bottom wall 1331 facing away from the front shell 11 is also provided with a glue overflow groove 1336, and the two ends of the glue overflow groove 1336 are respectively connected to the two adjacent glue filling ports 1333.

[0068] In this embodiment, the sealing wall 133 includes a bottom wall 1331 and side walls 1332. The bottom wall 1331 is generally parallel to the front face of the front housing 11 and defines a glue injection port 1333. When the front face is placed on a support surface, the glue injection port 1333 faces upward, facilitating the user's injection of glue into the glue injection cavity 139. Furthermore, a glue overflow groove 1336 is defined on the surface of the bottom wall 1331 facing away from the glue injection cavity 139. At least two glue injection ports 1333 are circumferentially disposed on the bottom wall 1331, with the ends of the glue overflow groove 1336 communicating with the two glue injection ports 1333. This arrangement allows glue to overflow from one of the glue injection ports 1333, allowing the overflowed glue to flow along the glue overflow groove 1336 to the other glue injection port 1333. This maintains a consistent glue level within the glue injection cavity 139 along the circumference of the rear housing 13, thereby preventing uneven glue distribution within the glue injection cavity 139.

[0069] In some embodiments, a processed step is provided on the surface of the bottom wall 1331 facing away from the glue filling cavity 139. At this time, a glue overflow surface 1335 is formed on the surface flush with the glue filling port 1333, and a glue overflow groove 1336 is provided on the step surface higher than the glue overflow surface 1335, thereby ensuring that the glue can fill the glue filling cavity 139 until it overflows onto the glue overflow surface 1335.

[0070] Please refer to Figure 2 and Figure 7 In some embodiments of the present application, the housing 110 further includes a glue-shielding ring 17 , which is disposed on the outer wall of the rear housing 13 and shields the glue injection port 1333 .

[0071] In this embodiment, the housing 110 further includes a sealant cover ring 17. After the sealant is injected into the sealant cavity 139, the sealant cover ring 17 can be used to cover the outside of the sealing wall 133 and seal the sealant opening 1333. This prevents the sealant opening 1333 from being exposed to the outside world and causing the sealant to overflow from the sealant opening 1333. It also prevents foreign matter from entering the sealant cavity 139 through the sealant opening 1333. In some embodiments, the camera 100 is used in an underwater environment. In this case, the sealant opening 1333 is prevented from being exposed, causing the sealant in the sealant cavity 139 to come into direct contact with water and accelerate its failure, thereby ensuring the shelf life of the sealant.

[0072] Please refer to Figure 5 and Figure 8 In some embodiments of the present application, the front housing 11 is provided with an installation opening 119 for connecting the outside and the installation cavity. The window 40 includes a window body 41 and a stopper 43. A portion of the window body 41 is inserted into the installation opening 119. The side of the window body 41 located in the installation cavity is provided with a stopper 43 that surrounds the window body 41.

[0073] The camera 100 further includes:

[0074] The window pressing cover 50 presses the stopper 43 and is provided with a avoiding hole 51 for exposing the window body 41; and

[0075] The first sealing ring 60 is sandwiched between the stopper 43 and the inner wall of the front shell 11 and is disposed around the circumference of the window 40 .

[0076] In the camera 100 , a transparent window 40 for light transmission is provided on the end face of the front shell 11 . Only the lens window 40 may be provided, or a fill light window 40 may be provided at the same time. Since the window 40 and the front shell 11 are mostly made of different materials, the window 40 is mostly installed on the front shell 11 . In this embodiment, the front shell 11 is provided with a mounting opening 119, and the window 40 includes a window body 41 and a stopper 43 protruding from the rear end side wall 1332 of the window body 41, so that the window body 41 is inserted into the mounting opening 119 from the inside to the outside, and the stopper 43 abuts against the inner wall of the shell 110 to limit the installation position of the window 40 to prevent the window 40 from falling out of the mounting opening 119; at the same time, a window pressure cover 50 is provided, and the window pressure cover 50 is connected and fixed to the inner wall of the shell 110 and pressed on the stopper 43 to fix the window 40. At the same time, a avoidance hole 51 arranged opposite to the window body 41 is provided on the window pressure cover 50, so that the lens assembly 30 or the fill light 90 is arranged from the avoidance hole 51 toward the window body 41.

[0077] In this embodiment, a first sealing ring 60 is sandwiched between the stop portion 43 and the inner wall of the shell 110. The first sealing ring 60 is made of an elastic material such as silicone or rubber. When the stop portion 43 is pressed against the inner wall of the shell 110 by the window cover 50, the first sealing ring 60 is compressed and deformed to fit tightly against the stop portion 43 and the inner wall of the shell 110, thereby filling the gap between the stop portion 43 and the inner wall of the shell 110, playing a sealing role, preventing foreign matter from entering the shell 110 from the window 40 area, improving the sealing performance of the camera 100, and making the camera 100 suitable for underwater environments or other similar environments, thereby improving the applicability of the camera 100.

[0078] Please refer to Figure 5In some embodiments of the present application, a first sealing rib 61 is protruding from the surface of the first sealing ring 60 facing the inner wall of the front shell 11, and a sealing groove is provided on the inner wall of the front shell 11. The first sealing rib 61 and the sealing groove are both arranged around the circumference of the window 40, and the first sealing rib 61 is embedded in the sealing groove.

[0079] In this embodiment, a first sealing rib is protruding from the surface of the first sealing ring 60 facing the inner wall of the shell 110 to increase the thickness of the first sealing ring 60, and the first sealing rib is elastically compressed by the pressure of the inner wall of the shell 110, so that the first sealing ring 60 can better fit closely with the inner wall of the shell 110, thereby improving the sealing performance between the stop portion 43 of the window 40 and the inner wall of the shell 110, and preventing foreign matter from entering the shell 110.

[0080] Please refer to Figure 5 In some embodiments of the present application, a second sealing rib 62 is protruding from the surface of the first sealing ring 60 facing the stop portion 43. The second sealing rib 62 is arranged around the circumference of the window 40 and abuts against the window cover 50.

[0081] In this embodiment, a second sealing rib is protruded on the surface of the first sealing ring 60 facing the stop portion 43 to increase the thickness of the first sealing ring 60, and the second sealing rib is elastically compressed by the pressure of the stop portion 43, so that the first sealing ring 60 can better fit closely with the stop portion 43, thereby improving the sealing performance between the stop portion 43 of the window 40 and the inner wall of the shell 110, and preventing foreign matter from entering the shell 110.

[0082] Please refer to Figure 5 In some embodiments of the present application, the camera 100 further includes a second sealing ring 70 , which is sandwiched between the window pressure cover 50 and the stopper 43 and is arranged around the circumference of the window 40 .

[0083] In this embodiment, a second sealing ring 70 is provided between the window cover 50 and the stopper 43 to form a sealed area between the inner surface of the window 40, the avoidance hole 51 of the window cover 50, and the fill light 90 or the lens assembly 30. This prevents foreign matter or moisture from entering the sealed area, which could cause the inner surface of the window 40 to become contaminated or fogged, thereby affecting the light transmission effect of the window 40. In some embodiments, the second sealing ring 70 includes a sealing portion and a connecting portion. The sealing portion is sandwiched between the stopper 43 and the window cover 50. The connecting portion protrudes from the inner ring 361 of the sealing portion and is inserted into the avoidance hole 51, affixing to the wall of the avoidance hole 51 to improve the connection strength between the second sealing ring 70, the window cover 50, and the window 40. The second sealing ring 70 is also limited in position to prevent the second sealing ring 70 from being offset and blocking the window 40.

[0084] Please refer to Figure 5 and Figure 8 In some embodiments of the present application, a glue retaining ring 117 is protruding from the inner wall of the front shell 11 and arranged around the window 40 . The glue retaining ring 117 is spaced apart from the side wall 1332 of the stopper 43 to form a glue filling space 2117 .

[0085] In this embodiment, a glue blocking ring 117 is protruded from the inner wall of the front shell 11 and is arranged around the window 40 to form a glue filling space 2117 between the glue blocking ring 117 and the side wall 1332 of the window 40. Sealant can be poured into the glue filling space 2117, which can not only improve the connection strength between the window 40 and the shell 110 and improve the structural stability of the camera 100; but also form a sealing area in the circumference of the window 40 to construct a multi-stage sealing structure formed by the first sealing ring 60 and the glue filling space 2117 between the window 40 and the front shell 11, thereby improving the sealing performance of the installation position of the window 40 and effectively isolating foreign matter from entering the shell 110 from the window 40 area.

[0086] Please refer to Figure 2 and Figure 6 In some embodiments of the present application, the rear housing 13 is provided with a plug hole 135, and the camera 100 further includes a cable assembly 80, the cable assembly 80 including a cable 81 and an SR structure 83 sleeved on the cable 81, the SR structure 83 being passed through the plug hole 135 so that one end of the cable 81 is passed through the mounting cavity and connected to the lens assembly 30;

[0087] The cable 81 and the inner wall of the SR structure 83 form a first glue-filling area 85 , and the hole wall of the plug hole 135 and the SR structure 83 form a second glue-filling area 87 .

[0088] In this embodiment, electronic components inside the camera 100, such as the lens assembly 30 or the fill light 90, are connected to an external power supply or other electronic devices through a cable assembly 80; wherein, the cable assembly 80 includes a cable 81 and an SR structure 83 sleeved on the cable 81, and the SR structure 83 is passed through the shell 110 and fixedly connected to the shell 110, so that one end of the cable 81 can extend into the shell 110 to be electrically connected to the internal components of the shell 110. The setting of the SR structure 83 can eliminate the stress of the cable 81 when it swings, prevent the core wire at the connection position between the cable 81 and the shell 110 from breaking, and can also be used to fix the cable 81 to the device structure.

[0089] In some embodiments, the SR structure 83 includes two connected sections, wherein a section of the SR structure 83 close to the outside of the shell 110 is tightly fitted with the cable 81, and a section close to the inner cavity of the shell 110 is loosely fitted with the cable 81, so that a first glue filling area 85 is formed between the section of the SR structure 83 and the cable 81, which can be used for filling sealant, that is, the connection strength between the SR structure 83 and the cable 81 can be improved through the bonding effect of the sealant, and the sealing performance between the SR structure 83 and the cable 81 can also be improved to prevent foreign matter from entering the shell 110 from between the SR structure 83 and the cable 81.

[0090] A section of the plug hole 135 close to the outside of the shell 110 is tightly fitted with the SR structure 83, and a section of the plug hole 135 close to the inner cavity of the shell 110 is loosely fitted with the SR structure 83, that is, the hole wall of this section of the plug hole 135 and the SR structure 83 are spaced apart to form a second glue pouring area 87, which can be used for pouring sealant, that is, the connection strength between the SR structure 83 and the shell 110 can be improved through the bonding effect of the sealant, and the sealing performance between the SR structure 83 and the hole wall of the plug hole 135 can also be improved to prevent external foreign matter from entering the shell 110 from between the SR structure 83 and the hole wall of the plug hole 135; in addition, a sealing ring 360 can be set between a section of the hole wall of the plug hole 135 close to the outside of the shell 110 and the SR structure 83 to further improve the sealing performance between the SR structure 83 and the hole wall of the plug hole 135. In some embodiments, a rim 137 surrounding the SR structure 83 can be protruded from the inner wall of the shell 110 to extend the length of the plug hole 135 and increase the volume of the second glue pouring area 87, so that more sealant can be poured between the SR structure 83 and the hole wall of the plug hole 135, further improving the sealing performance.

[0091] Furthermore, in some embodiments, a locking portion is protruded from the side wall 1332 at one end of the SR structure 83 located outside the shell 110, and the locking portion is pressed and locked to the outer wall of the shell 110 by a locking member such as a bolt. With such a configuration, when the camera 100 is used for image acquisition in an underwater environment, under the action of water pressure, the locking portion is subjected to pressure from the outside to the inside, so that the locking portion is tightly attached to the shell 110, thereby preventing the SR structure 83 from entering the shell 110 under the action of water pressure, resulting in failure of the seal at the position of the plug hole 135, thereby improving the sealing performance of the camera system 1000 in an underwater environment.

[0092] Please refer to Figures 11 to 14In some embodiments of the present application, the camera 100 is provided with a wiper mechanism, such that the oscillating path of the wiper 230 of the wiper mechanism passes through the viewing window 40 of the camera 100, thereby cleaning the viewing window 40 of the camera 100. The wiper mechanism and the camera 100 may share the same housing 110, i.e., the drive assembly 220 of the wiper mechanism and the lens assembly 30 of the camera 100 are disposed within the same housing 110. Alternatively, the wiper mechanism may be separately mounted on a housing 110 to form the wiper assembly 200, which is not limited herein.

[0093] Taking the example of the lens assembly 30 and the wiper mechanism being installed in different housings 110 respectively, the lens assembly 30 is installed on the first housing 110 to form a camera 100, and the wiper mechanism is installed on the second housing 210 to form a wiper assembly 200. The two are electrically connected through a cable assembly 80 to form a camera system 1000.

[0094] In some embodiments, the second shell 210 is arranged below the first shell 110 for supporting the first shell 110, and in order to improve the relative position stability between the second shell 210 and the first shell 110, the outer contour of at least the front end portion of the first shell 110 is set to be circular, and an arc-shaped groove adapted to the front end portion of the first shell 110 is set on the top surface of the second shell 210, so that the front end portion of the first shell 110 is accommodated in the arc-shaped groove. At this time, the first shell 110 and the second shell 210 can be prevented from being offset in the horizontal direction parallel to the front end surface. At this time, the first shell 110 and the second shell 210 can be connected and fixed by bolt connection or snap connection 213 in the following embodiment; after the first shell 110 and the second shell 210 are relatively fixed, the front end surface of the first shell 110 and the front end surface of the second shell 210 are roughly flush, and in the wiper assembly 200, the drive The assembly 220 is arranged in the second shell 210, so that the rotating shaft 240 of the driving assembly 220 passes through the front face of the second shell 210 and is parallel to the optical axis of the lens assembly 30 in the camera 100, that is, perpendicular to the front face of the first shell 110. The wiper 230 of the wiper assembly 200 is arranged on the front side of the front end of the second shell 210, and one end of the wiper 230 is connected to the rotating shaft 240, and a clamping screw 250 is sleeved on the end of the rotating shaft 240 away from the second shell 210, so that the wiper 230 is pressed and locked on the rotating shaft 240 by the clamping screw 250, so that it swings under the drive of the driving assembly 220, and at the same time, the swinging path of the wiper 230 passes through the front face of the first shell 110, so that the wiper 230 is in contact with the lens window 40 and the fill light window 40 during the swinging process; with such an arrangement, when the lens window 40 and the fill light window 40 are contaminated with dust and other debris, the wiper 230 can scrape off the debris.

[0095] In the wiper assembly 200 of the camera system 1000, since the rotating shaft 240 of the driving assembly 220 extends outward from the second shell 210, if the sealing performance between the rotating shaft 240 and the second shell 210 is poor, it is easy for foreign matter to enter the second shell 210. When the camera system 1000 is used in an underwater environment, water and foreign matter in the water are more likely to enter the second shell 210 under the action of water pressure.

[0096] In this embodiment, a sealing assembly 300 is provided in the wiper assembly 200, and the sealing assembly 300 includes a shaft sleeve 380, a first sealing sleeve 320 and a first sealing pressure plate 340; correspondingly, a through hole 2111 is opened on the front end surface of the second shell 210, which passes through the second shell 210, and the through hole 2111 includes a first limiting hole 2111c, a second limiting hole 2111b and a third limiting hole 2111a which are connected in sequence from the outside to the inside, and wherein the second limiting hole 2111b is a horn hole whose aperture gradually increases from the outside to the inside, and the first sealing sleeve 320 includes a first sealing ... The outer diameter of the first sealing section 321 increases from the outside to the inside, so that the first sealing sleeve 320 is inserted into the through hole 2111 from the inside of the second shell 210, and then the first sealing pressure plate 340 is fixed to the inner wall of the second shell 210 to compress the first sealing sleeve 320. At this time, the first sealing section 321 is inserted into the second limiting hole 2111b and the outer wall of the first sealing section 321 abuts against the hole wall of the second limiting hole 2111b, and the second sealing section 322 is inserted into the third limiting hole 2111a and the outer wall of the second sealing section 322 abuts against the hole wall of the third limiting hole 2111a. The hole wall abuts, and the first sealing sleeve 320 is made of elastic material such as silicone or rubber, so that when the first sealing sleeve 320 abuts against the hole wall of the through hole 2111, it generates elastic deformation to fit tightly against the hole wall of the through hole 2111; in addition, the shaft sleeve 380 is checked from the outside of the second shell 210 in the first limiting hole 2111c, so that the rotating shaft 240 is passed through the first sealing pressure plate 340, the first sealing sleeve 320 and the shaft sleeve 380, wherein the first sealing sleeve 320 and the rotating shaft 240 are interference fit so that the first sealing sleeve 320 is tightly attached to the surface of the rotating shaft 240, and is clamped between the rotating shaft 240 and the through hole 2111 The walls are compressed so that the first sealing sleeve 320 completely blocks the gap between the rotating shaft 240 and the wall of the through hole 2111, preventing foreign matter from entering the second shell 210 through the through hole 2111; further, since the outer diameter of the first sealing section 321 increases from the outside to the inside, the second limiting hole 2111b has a trumpet hole structure and squeezes the outer wall of the first sealing section 321, so that the first seal is deformed inward by the squeezing force from the outside to the inside of the wall of the second limiting hole 2111b, thereby pre-tightening the rotating shaft 240, ensuring that the inner wall of the first sealing sleeve 320 is close to the surface of the rotating shaft 240, thereby playing a better sealing role. When the camera 100 is used in an underwater environment, the first sealing section 321 is subjected to water pressure from the outside to the inside, further deforming toward the inside of the second shell 210 and clinging to the rotating shaft 240, thereby improving the sealing performance and effectively isolating foreign matter from entering the second shell 210; the first sealing pressure plate 340 can prevent the first sealing sleeve 320 from falling out of the through hole 2111 when subjected to external force from the outside to the inside.

[0097] In addition, the rotating shaft 240 and the first sealing pressure plate 340 and the shaft sleeve 380 are all clearance-fitted. The first sealing pressure plate 340 and the shaft sleeve 380 can serve as a limiter for the rotating shaft 240, so that the central axis of the rotating shaft 240 maintains a stable position, avoiding the rotating shaft 240 from tilting and bending during rotation, thereby ensuring that the circumferential compression of the first sealing sleeve 320 remains uniform, avoiding the gap between the first sealing sleeve 320 and the hole wall of the through hole 2111 at some circumferential positions due to the deviation of the rotating shaft 240, resulting in sealing failure.

[0098] Please refer to Figure 23 In some embodiments of the present application, the cable assembly 80 includes a cable 81 and SR structures 83 respectively provided on the surface of the cable 81, one end of the cable 81 is inserted into the second shell 210 and connected to the drive assembly 220, and the other end is inserted into the first shell 110 and electrically connected to the camera 100, wherein one SR structure 83 is fixed to the first shell 110, and the other SR structure 83 is fixed to the second shell 210.

[0099] In this embodiment, the wiper assembly 200 and the camera 100 are electrically connected via a cable assembly 80. One end of a cable 81 of the cable assembly 80 is passed through the second housing 210 and electrically connected to the drive assembly 220, while the other end is passed through the first housing 110 and connected to the camera 100. The cable 81 can be connected to a battery, a device or a circuit board provided in the first housing 110 for external power supply, etc., so that the wiper assembly 200 can be powered by the camera 100 or the wiper 230 can be driven to swing according to the program set on the circuit board or the received signal. In addition, an SR structure 83 can be sheathed on the outside of the cable 81, so that the cable 81 SR structure 83 is connected to the first housing 110 and the second housing 210. The provision of the SR structure 83 can eliminate stress on the cable 81 during swinging, prevent the core wire of the cable 81 from breaking at the connection point between the cable 81 and the first housing 110 or the second housing 210, and can also be used to fix the cable 81 to the device structure.

[0100] In some embodiments of the present application, both the first shell 110 and the second shell 210 are provided with a plug hole 135 for passing the SR structure 83;

[0101] A first glue potting area 85 is formed between the inner wall of the SR structure 83 and the cable 81 , and a second glue potting area 87 is formed between the hole wall of the plug hole 135 and the outer wall of the SR structure 83 .

[0102] In the camera system 1000 proposed in this application, the wiper assembly 200 and the camera 100 are connected via a cable assembly 80. To prevent damage to the cable 81 of the cable assembly 80, an SR structure 83 is provided for connecting to the first housing 110 and the second housing 210. In this embodiment, the two SR structures 83 on the cable assembly 80 are respectively inserted into the insertion holes 135 of the first housing 110 and the second housing 210. Each SR structure 83 includes two connected sections. The section of the SR structure 83 near the exterior of the housing 110 tightly fits the cable 81, while the section near the interior of the housing 110 loosely fits the cable 81. This creates a first glue-filling area 85 between the SR structure 83 and the cable 81, which can be used to inject sealant. This can improve the connection strength between the SR structure 83 and the cable 81 through the adhesive effect of the sealant, and can also improve the sealing performance between the SR structure 83 and the cable 81, preventing foreign matter from entering the first housing 110 and the second housing 210 through the gap between the SR structure 83 and the cable 81.

[0103] Taking the connection between the SR structure 83 and the first shell 110 as an example, a section of the plug hole 135 close to the outside of the first shell 110 is tightly matched with the SR structure 83, and a section of the plug hole 135 close to the inner cavity of the first shell 110 is loosely matched with the SR structure 83, that is, the hole wall of this section of the plug hole 135 and the SR structure 83 are spaced apart to form a second glue pouring area 87, which can be used for pouring sealant, that is, the connection strength between the SR structure 83 and the first shell 110 can be improved through the bonding effect of the sealant, and the sealing performance between the SR structure 83 and the hole wall of the plug hole 135 can also be improved to prevent external foreign matter from entering the first shell 110 from between the SR structure 83 and the hole wall of the plug hole 135; in addition, a sealing ring 360 can be set between a section of the hole wall of the plug hole 135 close to the outside of the first shell 110 and the SR structure 83 to further improve the sealing performance between the SR structure 83 and the hole wall of the plug hole 135. In some embodiments, a raised edge 137 surrounding the SR structure 83 can be formed on the inner wall of the first housing 110 to extend the length of the insertion hole 135 and increase the volume of the second glue potting area 87. This allows more sealant to be poured between the SR structure 83 and the wall of the insertion hole 135, further improving sealing performance. The connection structure between the second housing 210 and the SR structure 83 is similar to that between the first housing 110 and the SR structure 83 and will not be further described here.

[0104] Furthermore, in some embodiments, a locking portion is protruded from the side wall 1332 at one end of the SR structure 83 located outside the first shell 110 and the second shell 210, and the locking portion is pressed and locked to the outer walls of the first shell 110 and the second shell 210 by locking members such as bolts. With such a configuration, when the camera 100 is used for image acquisition in an underwater environment, under the action of water pressure, the locking portion is subjected to pressure from the outside to the inside, so that the locking portion is tightly attached to the first shell 110 and the second shell 210, thereby preventing the SR structure 83 from entering the first shell 110 and the second shell 210 under the action of water pressure, resulting in failure of the seal at the position of the plug hole 135, thereby improving the sealing performance of the camera system 1000 in an underwater environment.

[0105] Please refer to Figure 12 In some embodiments of the present application, a first wiring groove 136 extending to the bottom surface of the first housing 110 is recessed at one end of the first housing 110 away from the lens window 40 ;

[0106] A second wiring groove 2122 extending to the top surface of the second housing 210 is recessed at one end of the second housing 210 away from the wiper 230 . The second wiring groove 2122 is connected to the first wiring groove 136 , and part of the cable 81 is embedded in the first wiring groove 136 and the second wiring groove 2122 .

[0107] In the camera system 1000 proposed in this application, the wiper assembly 200 and the camera 100 are connected via a cable assembly 80. In this embodiment, a first wiring groove 136 is recessed at the rear end of the first housing 110, i.e., the end of the first housing 110 facing away from the fill light window 40 and the lens window 40. A second wiring groove 2122 is recessed at the rear end of the second housing 210, i.e., the end facing away from the wiper 230. The first wiring groove 136 and the second wiring groove 2122 are interconnected for embedding the cable 81. This allows the cable 81 to be positioned, preventing the cable 81 from swinging due to external forces, which could loosen the connection between the SR structure 83 and the first housing 110 and the second housing 210.

[0108] Please refer to Figure 12 In some embodiments of the present application, the camera 100 further includes a first wire shielding cover 19 , and the first wire shielding cover 19 is disposed on the first wire routing groove 136 ;

[0109] The wiper assembly 200 further includes a second wire shielding cover 216 , which is disposed on the second wire routing groove 2122 .

[0110] In this embodiment, a first wire shielding cover 19 and a second wire shielding cover 216 are provided to cover the first wire trough 136 and the second wire trough 2122, respectively, to conceal the cables 81 embedded in the first wire trough 136 and the second wire trough 2122. This protects the cables 81 and prevents them from being directly exposed to the outside world, thereby reducing the risk of damage to the cables 81 and preventing them from being cut or worn by foreign objects. The first wire shielding cover 19 and the first housing 110 may be connected by a buckle 213 or fastened by bolts, and the second wire shielding cover 216 and the second housing 210 may also be connected by a buckle 213 or fastened by bolts, without specific limitations herein.

[0111] Please refer to Figure 13 In some embodiments of the present application, the bottom wall 1331 of the first housing 110 is provided with a first connection hole 18, and the top wall of the second housing 210 is provided with a second connection hole 214, and the first connection hole 18 and the second connection hole 214 are arranged opposite to each other;

[0112] The camera system 1000 further includes a locking member, which is passed through the first connecting hole 18 and the second connecting hole 214 to connect the camera 100 and the wiper assembly 200 .

[0113] It can be understood that the camera system 1000 of the present application is composed of a camera 100 and a wiper assembly 200 that are connected, and the camera 100 is carried on the wiper assembly 200. In this embodiment, the camera 100 and the wiper assembly 200 are connected and fixed by a locking member such as a bolt, wherein a first connecting hole 18 is opened on the bottom wall 1331 of the first shell 110 of the camera 100, and a second connecting hole 214 is opened on the top wall of the second shell 210 of the wiper 230 and is arranged opposite to the first connecting hole 18. One of the first connecting hole 18 and the second connecting hole 214 can be a screw hole, and the locking member is set as a bolt, so that the bolt is passed through the first connecting hole 18 and the second connecting hole 214 and is bolted to the screw holes therein. It can also be set as a combined connection structure of a bolt and a nut, so that the first shell 110 and the second shell 210 are connected by bolts, thereby improving the structural stability of the camera system 1000, avoiding displacement of the camera 100 and the wiper assembly 200, and ensuring that the swing path of the wiper 230 passes through the fill light window 40 and the lens window 40 so that the wiper 230 can wipe and clean the fill light window 40 and the lens window 40 during the swinging process.

[0114] It should be noted that the technical solution of the present application provides for a circular cross-section at the front end of the first housing 110 so that the front end of the first housing 110 is accommodated in the arc-shaped groove on the top surface of the second housing 210. In this case, if the entire first housing 110 is configured as a cylindrical structure, the first and second housings 110, 210 can rotate relative to each other in the circumferential direction when connected to the second housing 210, making it difficult to align the first connection hole 18 with the second connection hole 214. In this embodiment, the bottom surface of the rear end of the first housing 110 can be configured as a flat surface, and the top surface of the rear end of the second housing 210 can be configured as a flat surface. This allows the first and second housings 110, 210 to be circumferentially positioned by the abutment of the two flat surfaces, which also facilitates the alignment of the first and second connection holes 18, 214. Of course, the alignment between the first and second connection holes 18, 214 can also be assisted by positioning structures in the following embodiments, which will not be described in detail here.

[0115] Please refer to Figure 13 In some embodiments of the present application, the bottom wall 1331 of the first shell 110 is provided with one of the positioning portion 215 and the positioning hole, and the top wall of the second shell 210 is provided with the other of the positioning portion 215 and the positioning hole, and the positioning portion 215 is inserted into the positioning hole.

[0116] In the technical solution of the aforementioned embodiment, the first shell 110 and the second shell 210 are connected and fixed by the locking member penetrating the first connecting hole 18 and the second connecting hole 214 which are oppositely arranged and communicated. In order to ensure that the first connecting hole 18 and the second connecting hole 214 are accurately aligned and the wiper assembly 200 and the camera 100 maintain a fixed relative position, in this embodiment, a plug-in positioning portion 215 and a positioning hole are provided between the first shell 110 and the second shell 210. The positioning portion 215 can be provided on the bottom wall 1331 of the first shell 110 or on the top wall of the second shell 210. Correspondingly, positioning holes are provided on the top wall of the second shell 210 and the bottom wall 1331 of the first shell 110. When assembling the camera system 1000, it is only necessary to insert the positioning portion 215 into the positioning hole to ensure that the camera 100 and the wiper assembly 200 are aligned. The swing path of the wiper 230 can pass through the fill light window 40 and the lens window 40 of the camera 100; and it can be ensured that the first connecting hole 18 and the second connecting hole 214 are already relatively arranged. It is only necessary to insert a locking member to connect and fix them, thereby improving the assembly efficiency of the camera system 1000.

[0117] Please refer to Figure 13In some embodiments of the present application, the bottom wall 1331 of the first shell 110 is provided with one of the snap-fit hole 16 and the snap-fit 213, and the top wall of the second shell 210 is provided with the other of the snap-fit hole 16 and the snap-fit 213, and the snap-fit 213 is snapped into the snap-fit hole 16.

[0118] In this embodiment, a snap-fitting snap 213 and a snap-fitting hole 16 are provided between the first shell 110 and the second shell 210. Taking the snap 213 being provided on the top wall of the second shell 210 and the snap-fitting hole 16 being provided on the bottom wall 1331 of the first shell 110 as an example, the snap 213 is provided with a hook at one end, the hook is provided toward the top wall of the second shell 210, and the hole wall of the snap-fitting hole 16 is provided with a convex snap-fitting portion or a concave snap-fitting groove. When the snap 213 is inserted into the snap-fitting hole 16, the hook is hooked on the snap-fitting portion or the groove wall of the snap-fitting groove to prevent the snap 213 from coming out of the snap-fitting hole 16, thereby connecting the second shell 210 to the first shell 110. Then, at this time, the camera 100 and the wiper assembly 200 have been aligned, and the swing path of the wiper 230 can pass through the fill light window 40 and the lens window 40 of the camera 100; and it can be ensured that the first connecting hole 18 and the second connecting hole 214 are already relatively set, and only a locking part needs to be inserted to connect and fix them, which can not only improve the assembly efficiency of the camera system 1000, but also the first shell 110 and the second shell 210 are connected and fixed by the buckle 213 connection and the bolt connection, which can also improve the connection strength between the first shell 110 and the second shell 210, thereby improving the structural stability of the camera system 1000.

[0119] Please refer to Figure 15 and Figure 16 In some embodiments of the present application, the inclination angle of the hole wall of the second limiting hole 2111b is greater than the inclination angle of the outer wall of the first sealing section 321, and the compression amount of the first sealing section 321 squeezed by the hole wall of the second limiting hole 2111b is 0.2mm to 0.5mm.

[0120] In order for the first sealing segment 321 to grip the rotating shaft 240 tightly, it is necessary for the first sealing segment 321 to have a gripping force along the radial direction of the rotating shaft 240. In this embodiment, the outer wall inclination angle of the first sealing segment 321 is smaller than the inclination angle of the hole wall of the second limiting hole 2111b. This configuration allows the second limiting hole 2111b to apply force to the first sealing segment 321 in both the axial and radial directions of the rotating shaft 240 when the first sealing segment 321 is squeezed by the hole wall of the second limiting hole 2111b, thereby allowing the first sealing segment 321 to deform inward and grip the rotating shaft 240 tightly.

[0121] In addition, when the first sealing section 321 is squeezed by the hole wall of the second limiting hole 2111b, the compression amount of the outer wall of the first sealing section 321 is between 0.5mm and 1.2mm, which can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 09mm, 1.0mm, 1.1mm, 1.2mm or any value between 0.5mm and 1.2mm, which is not limited here; such a setting can ensure that the first sealing section 321 is fully in close contact with the hole wall of the second limiting hole 2111b, ensure that there is good sealing performance between the first sealing sleeve 320 and the through hole 2111, and effectively isolate external foreign matter from entering the second shell 210.

[0122] In some embodiments, the end surface of the second sealing segment 322 close to the first sealing segment 321 is provided with a limiting portion arranged around the first sealing segment 321, and the aperture of the third limiting hole 2111a is larger than the maximum aperture of the second limiting hole 2111b, so that a limiting step surrounding the second limiting hole 2111b is formed on the bottom wall 1331 of the third limiting hole 2111a. When the first sealing sleeve 320 is inserted into the through hole 2111, the limiting portion abuts against the limiting step to limit the insertion depth of the first sealing sleeve 320, and at the same time, the degree of extrusion between the first sealing segment 321 and the hole wall of the second limiting hole 2111b can be limited, so that the compression amount of the first sealing segment 321 is within a preset compression amount range.

[0123] Please refer to Figure 16 and Figure 20 In some embodiments of the present application, the inner wall of the first sealing sleeve 320 is provided with at least two sealing lips 326 arranged at intervals along the axial direction of the rotating shaft 240. The sealing lips 326 are enclosed to form a through hole for the rotating shaft 240 to pass through. The aperture of the through hole gradually increases from the outside to the inside, so that the sealing lips 326 can deform from the outside to the inside and hold the rotating shaft 240 tightly.

[0124] In this embodiment, at least two sealing lips 326 are protruding from the inner wall of the first sealing sleeve 320. The sealing lips 326 extend from the inside to the outside and gradually approach the rotating shaft 240 until the end of the sealing lips 326 contacts the surface of the rotating shaft 240. At this time, each sealing lip 326 is arranged along the circumference of the rotating shaft 240 to form a through hole for the rotating shaft 240 to pass through, and the aperture of the through hole gradually increases from the outside to the inside. In this arrangement, when the sealing lips 326 are subjected to external pressure, such as water pressure, the sealing lips 326 deform into the second shell 210 and tightly embrace the rotating shaft 240, thereby providing a better sealing effect and preventing foreign matter from entering the second shell 210. The provision of the through hole prevents the sealing lips 326 from encountering large resistance when deforming. It can be understood that the provision of at least two sealing lips 326 can form a multi-level barrier sealing effect, effectively improving the sealing performance. In some embodiments, the sealing lip 326 may be protruded from the inner wall of the second sealing section 322 , and the first sealing section 321 is formed when the sealing lip 326 closest to the wiper 230 in the second sealing section 322 extends outward.

[0125] In some embodiments of the present application, the amount of compression when the sealing lip 326 and the rotating shaft 240 are squeezed and fitted is 0.5 mm to 1.2 mm.

[0126] In this embodiment, when the first sealing sleeve 320 is clamped between the hole wall of the through hole 2111 and the rotating shaft 240, and when the sealing lip 326 is subjected to an external force from the outside to the inside, the sealing lip 326 is elastically compressed to fit tightly against the rotating shaft 240. At this time, the compression amount of the sealing lip 326 is between 0.5mm and 1.2mm, which can be 0.5mm, 0.6mm, 0.7mm, 0.8mm, 09mm, 1.0mm, 1.1mm, 1.2mm or any value between 0.5mm and 1.2mm, which is not limited here; such a setting can ensure that the sealing lip 326 fully hugs the rotating shaft 240 tightly, ensures that there is good sealing performance between the first sealing sleeve 320 and the rotating shaft 240, and effectively isolates external foreign matter from entering the second shell 210.

[0127] Please refer to Figure 16 In some embodiments of the present application, a first crimping rib 324 is protruded from the outer wall of the second sealing section 322. The first crimping rib 324 is arranged around the circumference of the first sealing sleeve 320 and is squeezed and fitted with the wall of the third limiting hole 2111a.

[0128] The cam 324 is provided on the outer wall of the second sealing section 322, and the cam 324 is arranged around the second sealing section 322. When the first sealing sleeve 320 is inserted into the through hole 2111, the cam 324 and the wall of the third limiting hole 2111a are pressed and fitted with each other. In this way, the first cam 324 increases the local outer diameter of the second sealing section 322, so that the second sealing section 322 can be fully blocked between the third limiting hole 2111a and the rotating shaft 240, thereby increasing the compression amount of the second sealing section 322 and improving the sealing performance. It also avoids the outer diameter of the entire second sealing section 322 increasing, which makes it difficult for the first sealing sleeve 320 to be inserted into the through hole 2111. At least two first cam 324 can be provided, and the at least two first cam 324 are arranged in sequence along the axial direction of the rotating shaft 240, so as to play the role of multi-stage sealing and improve the sealing performance.

[0129] Please refer to Figure 16 In some embodiments of the present application, a crimping portion 323 is provided on the outer wall of one end of the second sealing segment 322 away from the first sealing segment 321 , and the crimping portion 323 is provided around the circumference of the first sealing sleeve 320 ;

[0130] A second crimping rib 325 is protruded from the inner wall of the crimping portion 323 facing the second housing 210 . The first sealing plate 340 presses the crimping portion 323 so that the second crimping rib 325 is pressed against the inner wall of the second housing 210 .

[0131] In the technical solution of the aforementioned embodiment, the first sealing sleeve 320 is pressed into the through-hole 2111 by a first sealing pressure plate 340 fixed to the inner wall of the second housing 210. In this embodiment, the first sealing sleeve 320 has a crimping portion 323 protruding from the side wall 1332 of the second sealing section 322, which is away from the first sealing section 321. The crimping portion 323 is located outside the through-hole 2111 and is sandwiched between the first sealing pressure plate 340 and the inner wall of the second housing 210. This arrangement allows the crimping portion 323 to limit the insertion depth of the first sealing sleeve 320, preventing the first sealing sleeve 320 from fully entering the through-hole 2111. The compression portion is clamped to prevent the first sealing sleeve 320 from rotating with the rotating shaft 240. The amount of compression between the first sealing section 321 and the wall of the second limiting hole 2111b can also be limited.

[0132] Furthermore, a second crimping rib 325 is protruding from the surface of the compression part facing the inner wall of the second shell 210. The second crimping rib 325 is arranged around the circumference of the rotating shaft 240, so that the second crimping rib 325 is squeezed and fitted with the inner wall of the second shell 210, thereby further playing a sealing role, improving the sealing effect of the first sealing sleeve 320 on the through hole 2111, and preventing foreign matter from entering the second shell 210 from between the first sealing sleeve 320 and the through hole 2111.

[0133] Please refer to Figure 15 In some embodiments of the present application, the first sealing pressure plate 340 is provided with a first locking hole, and the inner wall of the second shell 210 is provided with a second locking hole. The wiper assembly 200 also includes a locking member, which is sequentially passed through the first locking hole and the second locking hole from the inside to the outside of the second shell 210 to lock the first sealing pressure plate 340 to the inner wall of the second shell 210.

[0134] In this embodiment, the first sealing pressure plate 340 is locked to the inner wall of the second shell 210 by a locking member such as a bolt, wherein a first locking hole is opened on the first sealing pressure plate 340, and the first locking hole is a through hole, and a second locking hole is opened on the inner wall of the second shell 210, and the second locking hole is a screw hole and a blind hole. The locking member is set as a bolt, and the locking member is passed through the first locking hole from the side of the first sealing pressure plate 340 away from the first sealing sleeve 320 and inserted into the second locking hole and threadedly connected to the second locking hole to lock the first sealing pressure plate 340 to the inner wall of the second shell 210, so that the first sealing pressure plate 340 is subjected to pressure from the inside to the outside to compress the first sealing sleeve 320.

[0135] In some embodiments, an extension portion 2115 is protruded from the inner wall of the second shell 210, and the through hole 2111 passes through the extension portion 2115 to avoid the depth of the through hole 2111 being limited by the shell wall thickness of the second shell 210, so that the through hole 2111 has sufficient length for installing the shaft sleeve 380 and the first sealing sleeve 320. At this time, the first sealing pressure plate 340 is pressed on the end face of the extension portion 2115.

[0136] Please refer to Figures 15 to 19 In some embodiments of the present application, the sealing assembly 300 further includes:

[0137] A sealing bracket 310 is formed into a cylindrical structure with one end open. The opening of the sealing bracket 310 is disposed on the inner wall of the second housing 210 to form a sealed space within the sealing bracket 310. A mounting hole 311 is formed at one end of the sealing bracket 310 facing away from the wiper 230; and

[0138] The second sealing sleeve 330 is inserted into the mounting hole 311 , the rotating shaft 240 passes through the second sealing sleeve 330 , and the second sealing sleeve 330 is elastically squeezed between the rotating shaft 240 and the hole wall of the mounting hole 311 .

[0139] In this embodiment, the sealing assembly 300 further includes a sealing bracket 310 and a second sealing sleeve 330. The sealing bracket 310 is a cylindrical structure with one end open. The cross-sectional shape of the sealing bracket 310 can be polygonal, circular or other regular or irregular shapes, which are not limited here. The sealing bracket 310 is fixed to the inner wall of the second shell 210, so that the inner wall of the second shell 210 with the through hole 2111 blocks the opening of the sealing bracket 310 to form a sealed space in the sealing bracket 310. At the same time, the bottom wall 1 of the sealing bracket 310, which is arranged opposite to the inner wall of the second shell 210, is provided. A mounting hole 311 is defined in the housing 331 for receiving the rotating shaft 240. A second sealing sleeve 330 is inserted into the mounting hole 311 and then sleeved onto the rotating shaft 240. The second sealing sleeve 330 is made of an elastic material such as silicone or rubber. When sandwiched between the wall of the mounting hole 311 and the rotating shaft 240, the second sealing sleeve 330 compresses and deforms, causing the second sealing sleeve 330 to adhere tightly to the wall of the mounting hole 311 and the outer surface of the rotating shaft 240, effectively blocking the gap between the wall of the mounting hole 311 and the rotating shaft 240, providing a good sealing effect and preventing damage to the sealing space. This arrangement allows the rotating shaft 240 to sequentially pass through the first sealing sleeve 320, the sealing bracket 310, and the second sealing sleeve 330, thereby forming a multi-stage seal within the second housing 210 along the axial direction of the rotating shaft 240 from the inside out. This effectively improves the sealing performance of the rotating shaft 240 and prevents foreign matter from entering the second housing 210 along the rotating shaft 240.

[0140] Please refer to Figure 21 An isolation ring 314 is provided in the mounting hole 311 to separate the mounting hole 311 into two sealing grooves with openings facing back to back. At least one second sealing sleeve 330 is provided in each sealing groove, so that at least two levels of sealing can be formed at the mounting hole 311 to improve the sealing performance of the mounting bracket. The setting of the sealing ring can also limit the rotating shaft 240, so that the central axis of the rotating shaft 240 maintains a stable position, thereby avoiding the rotating shaft 240 from tilting during rotation, and making the circumferential compression of the first sealing sleeve 320 and the second sealing sleeve 330 uniform.

[0141] Please refer to Figure 21 A fixing ear 317 is protruded from the outer wall of the sealing bracket 310, and a first fixing hole 3171 is opened on the fixing ear 317. A second fixing hole 2112 is opened on the inner wall of the second shell 210, and the second fixing hole 2112 is arranged opposite to the first fixing hole 3171. The camera 100 also includes a locking piece, which is passed through the first fixing hole 3171 and the second fixing hole 2112 to fix the sealing bracket 310.

[0142] It can be understood that in the wiper assembly 200, a sealing bracket 310 needs to be covered on the inner wall of the second shell 210 to form a sealing area. In this embodiment, a fixing ear 317 is protruded from the outer wall 1332 of the sealing bracket 310, and a first fixing hole 3171 is opened on the fixing ear 317, and a second fixing hole 2112 is opened on the inner wall of the second shell 210. The second fixing hole 2112 can be set as a screw hole and a blind hole, and a bolt is used as a locking member, so that the locking member is passed through the first fixing hole 3171 and threadedly connected with the second fixing hole 2112 to fix the sealing bracket 310 on the inner wall of the second shell 210, and at this time the locking member presses the sealing bracket 310 against the inner wall of the shell 110 from the inside to the outside, which is more conducive to improving the sealing performance of the sealing bracket 310.

[0143] In some embodiments, the surface of the fixing ear 317 facing the inner wall of the shell 110 component is provided with one of the positioning hole 3172 and the positioning column 2113, and the inner wall of the second shell 210 is provided with the other of the positioning hole 3172 and the positioning column 2113, and the positioning column 2113 is inserted into the positioning hole 3172.
