[0030] A wiper assembly, which includes a second housing, a driving assembly and a wiper. The top of the second housing supports the first housing. A cable passing through the second housing extends into the first housing and is electrically connected to the camera. Wherein the driving assembly includes a rotating shaft with an axis, and the axis is parallel to the optical axis of the camera. The middle part of the rotating shaft extends out of the front end face of the second housing and is then fixedly connected to the wiper to drive the wiper to swing against the window;
[0031] Wherein, the front end face of the second housing includes a through hole extending along the axis, and the through hole sequentially includes a second limiting hole and a third limiting hole.

The minimum radius of the first sealing section is greater than the minimum radius of the second limiting hole, and the radius of the protrusion of the second sealing section is greater than the maximum radius of the third limiting hole, so that the outer surface of the first sealing sleeve and the inner surface of the through hole are sequentially subjected to a first radial force formed by the second limiting hole and the first sealing section and a second radial force formed by the third limiting hole and the second sealing section, thereby forming a sealed cavity inside the second housing.
[0034] The present application also provides a camera system, including:
[0035] A camera, the camera includes a first housing and a window disposed at the front end of the first housing;
[0036] A wiper assembly, the wiper assembly includes a second housing, a rotating shaft and a wiper. The top end of the second housing supports the first housing. The axis of the rotating shaft is parallel to the optical axis of the camera. Under the action of a driving force, the rotating shaft drives the wiper to swing along the window;
[0037] Wherein, the wiper assembly further includes:

Wherein, the through hole accommodates the first sealing sleeve so that the inner circumference of the through hole and the outer circumference of the first sealing sleeve form a first sealing area and a second sealing area. The first sealing area is formed by the radial abutment of the second limiting hole and the first sealing section, and the second sealing area is formed by the radial abutment of the third limiting hole and the second sealing section. The sealing bracket is relatively fastened to the second housing, thereby preventing substances in water from entering the second housing through the first sealing area, the second sealing area, the sealing bracket, and the two second sealing sleeves.

The radial radius of any truncated cone is less than the radial radius of the rotating shaft.
[0048] The compression screw is sleeved on the rotating shaft and is located at one end of the wiper away from the second housing to compress the wiper;
[0049] The wiper assembly is configured such that: along the inward direction of the axis of the rotating shaft, the first limiting hole houses the shaft sleeve, the second limiting hole houses the first sealing section, and the third limiting hole houses the second sealing section, so that the inner circumference of the through hole is sequentially abutted against the first limiting hole by the outer circumference of the shaft sleeve, abutted against the second limiting hole by the first sealing section, and abutted against the third limiting hole by the second sealing section, thereby sealing the through hole. At the same time, the rotating shaft is sequentially subjected to the pressing forces of the inner wall of the shaft sleeve, the inner wall of the first sealing section, and the inner wall of the second sealing section, so that the axis of the rotating shaft does not deviate during rotation.
[0050] The present application also provides a camera system, including:

[0056] The second sealing sleeve is sleeved on the rotating shaft and inserted into the mounting hole to be clamped between the rotating shaft and the hole wall of the mounting hole.
[0057] The camera system of the present invention includes a camera and a wiper assembly. The wiper of the wiper assembly can swing along the plane where the viewing window of the camera is located under the drive of the driving assembly, so that the viewing window can be wiped and cleaned when debris adheres to the viewing window.
[0058] Meanwhile, a sealing assembly is provided on the second housing which serves as the support base of the wiper assembly. The second housing is successively provided with a first limiting hole, a second limiting hole and a third limiting hole which are interconnected from outside to inside. Among them, the second limiting hole is a trumpet hole structure with a gradually expanding aperture from the outside to the inside of the second housing; the sealing assembly includes a bushing and a first sealing sleeve. The bushing is inserted into the first limiting hole from outside to inside. The first sealing sleeve includes a connected first sealing section and a second sealing section. The outer diameter of the first sealing section gradually contracts in a direction away from the second sealing section. When the first sealing sleeve is inserted into the second limiting hole and the third limiting hole from inside to outside, the first sealing section is inserted into the second limiting hole, and the second sealing section is inserted into the third limiting hole. Then, the first sealing pressing plate presses and fixes the first sealing sleeve. Under the action of water pressure, the first sealing section deforms from outside to inside to tightly hold the rotating shaft, playing a good sealing role; when the rotating shaft of the wiper passes through the bushing and the first sealing sleeve, the bushing can fix the position of the rotating shaft, and the first sealing sleeve is respectively squeezed by the hole walls of the second limiting hole and the third limiting hole at the first sealing section and the second sealing section, so that the inner wall of the first sealing sleeve squeezes and tightly adheres to the rotating shaft, making the position and axis of the rotating shaft stable under the squeezing of the inner first sealing sleeve and the limiting action of the outer bushing, effectively avoiding the inclination and bending of the rotating shaft during rotation, thus avoiding the problem of sealing failure at the rotating shaft due to uneven circumferential compression of the sealing sleeve, improving the sealing performance of the wiper assembly at the rotating shaft position, so that the camera system can be applied to the underwater environment.

[0063] The realization, functional features and advantages of the present invention will be further described in conjunction with embodiments and with reference to the accompanying drawings. Detailed implementation manners
[0064] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0065] The present invention provides a camera system 1000.
[0066] Please refer to Figure 1 and Figures 14 to 16 , in some embodiments of the present application, the camera system 1000 includes:
[0067] A camera 100, the camera 100 includes a first housing 110 and a lens assembly 30 disposed in the first housing 110, and a viewing window 40 is provided on the first housing 110; and
[0068] A wiper assembly 200, the wiper assembly 200 supports the camera 100, the wiper assembly 200 includes a second housing 210, a driving assembly 220 disposed in the second housing 210, and a wiper 230 disposed outside the second housing 210. A rotating shaft 240 of the driving assembly 220 is parallel to the optical axis of the lens assembly 30 and passes through the second housing 210 to be connected to the wiper 230, so as to drive the wiper 230 to swing against the viewing window 40;
[0069] The second housing 210 is provided with a first limiting hole 2111c, a second limiting hole 2111b and a third limiting hole 2111a that are sequentially communicated from outside to inside. Both the first limiting hole 2111c and the third limiting hole 2111a are straight holes, the aperture of the second limiting hole 2111b gradually increases from outside to inside, and the apertures of both the first limiting hole 2111c and the third limiting hole 2111a are larger than the minimum aperture of the second limiting hole 2111b;
[0070] The windshield wiper assembly 200 further includes a sealing assembly 300. The sealing assembly 300 includes a bushing 380 fixed to the first limiting hole 2111c, a first sealing sleeve 320, and a first sealing pressure plate 340 fixed to the inner wall of the second housing 210 and extruding the first sealing sleeve 320 outward. The first sealing sleeve 320 has a first sealing section 321 inserted into the second limiting hole 2111b and a second sealing section 322 inserted into the third limiting hole 2111a. The outer diameter of the first sealing section 321 gradually increases from outside to inside.
[0071] The rotating shaft 240 sequentially passes through the first sealing pressure plate 340, the first sealing sleeve 320, and the bushing 380. The bushing 380 and the first sealing pressure plate 340 limit the rotating shaft 240 from both sides of the second housing 210 to prevent the central axis of the rotating shaft 240 from shifting. The first sealing sleeve 320 is evenly and elastically compressed between the surface of the rotating shaft 240 and the hole walls of the third limiting hole 2111a and the second limiting hole 2111b.
[0072] The camera system 1000 proposed in this application mainly includes a camera 100 and a wiper assembly 200. The camera 100, as the main functional component for image acquisition, includes a first housing 110 as the bearing base, a fill light 90 and a lens assembly 30 disposed within the first housing 110. It is defined that the camera 100 has a front-back direction, and the front end of the camera 100 is set towards the position to be observed. A window 40 is provided on the front end face of the first housing 110. It can be only the lens window 40, and in some embodiments, the fill light window 40 and the lens window 40 can also be provided simultaneously. The fill light 90 within the first housing 110 is set towards the fill light window 40, and the lens assembly 30 is set towards the lens window 40. Thus, 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, improving the brightness of the position to be observed and making the image collected by the lens assembly 30 clearer. The setting of the wiper assembly 200 is intended to clean the lens window 40 and the fill light window 40 through the swinging wiper 230. The wiper assembly 200 includes a second housing 210 as the bearing base, a drive assembly 220 and a wiper 230 disposed on the first housing 110. The second housing 210 is disposed below the first housing 110 for carrying the first housing 110. And in order to improve the relative position stability between the second housing 210 and the first housing 110, at least the outer contour of the front end portion of the first housing 110 is set to be circular. An arc-shaped groove adapted to the front end portion of the first housing 110 is provided on the top surface of the second housing 210, so that the front end portion of the first housing 110 is received within the arc-shaped groove. At this time, the deviation of the first housing 110 and the second housing 210 in the horizontal direction parallel to the front end face can be avoided. At this time, the first housing 110 and the second housing 210 can be connected and fixed by means such as bolt connection or snap connection 213 as in the following embodiments. After the first housing 110 and the second housing 210 are relatively fixed, the front end face of the first housing 110 and the front end face of the second housing 210 are substantially flush. In the wiper assembly 200, the drive assembly 220 is disposed within the second housing 210, so that the rotating shaft 240 of the drive assembly 220 passes through the front end face of the second housing 210 and is parallel to the optical axis of the lens assembly 30 in the camera 100, that is, perpendicular to the front end face of the first housing 110. The wiper 230 of the wiper assembly 200 is disposed on the front side of the front end face of the second housing 210, and one end of the wiper 230 is connected to the rotating shaft 240 to swing under the drive of the drive assembly 220. At the same time, the swinging path of the wiper 230 passes through the front end face of the first housing 110, so that the wiper 230 fits against the lens window 40 and the fill light window 40 during the swinging process. With such a setting, 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.
[0073] In the wiper assembly 200 of the camera system 1000, since the rotating shaft 240 of the driving assembly 220 passes outwards from within the second housing 210, if the sealing performance between the rotating shaft 240 and the second housing 210 is poor, it is easy for foreign objects from the outside to enter the second housing 210. When the camera system 1000 is applied to an underwater environment, under the action of water pressure, water and foreign objects in the water are more likely to enter the second housing 210.
[0074] In this embodiment, a sealing assembly 300 is provided in the wiper assembly 200. The sealing assembly 300 includes a bushing 380, a first sealing sleeve 320, and a first sealing pressure plate 340. Correspondingly, a through hole 2111 that penetrates into the second housing 210 is formed in the front end face of the second housing 210. The through hole 2111 includes a first limiting hole 2111c, a second limiting hole 2111b, and a third limiting hole 2111a that are connected in sequence from outside to inside. Among them, the second limiting hole 2111b is a flared hole with a gradually increasing hole diameter from outside to inside. The first sealing sleeve 320 includes a connected first sealing section 321 and a second sealing section 322. The outer diameter of the first sealing section 321 increases from outside to inside, so that the first sealing sleeve 320 is inserted into the through hole 2111 from the inside of the second housing 210. Then, the first sealing pressure plate 340 is fixed to the inner wall of the second housing 210 to press 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. 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 first sealing sleeve 320 is made of an 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 undergoes elastic deformation to closely adhere to the hole wall of the through hole 2111. In addition, the bushing 380 is inserted into the first limiting hole 2111c from the outside of the second housing 210, so that the rotating shaft 240 passes through the first sealing pressure plate 340, the first sealing sleeve 320, and the bushing 380. An interference fit is provided between the first sealing sleeve 320 and the rotating shaft 240 so that the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240. It is clamped between the rotating shaft 240 and the hole wall of the through hole 2111 and is compressed so that the first sealing sleeve 320 completely seals the gap between the rotating shaft 240 and the hole wall of the through hole 2111, preventing foreign objects from entering the second housing 210 from the through hole 2111. Further, since the outer diameter of the first sealing section 321 increases from outside to inside and the second limiting hole 2111b has a flared hole structure and presses against the outer wall of the first sealing section 321, the first seal is deformed inward by the inward squeezing force of the hole wall of the second limiting hole 2111b from outside to inside, thereby pre-clamping the rotating shaft 240 to ensure that the inner wall of the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240, achieving a better sealing effect. Refer to Figure 20When the camera 100 is applied to an underwater environment, the first sealing section 321 is subjected to the water pressure acting from the outside to the inside, further deforms into the second housing 210 and closely adheres to the rotating shaft 240, improving the sealing performance and effectively isolating foreign objects from entering the second housing 210; the function of the first sealing pressing plate 340 can prevent the first sealing sleeve 320 from being disengaged from the through hole 2111 when subjected to an external force acting from the outside to the inside.
[0075] In addition, the rotating shaft 240 has a clearance fit with both the first sealing pressing plate 340 and the bushing 380. The first sealing pressing plate 340 and the bushing 380 can play a role in limiting the rotating shaft 240, keeping the central axis of the rotating shaft 240 in a stable position, preventing the rotating shaft 240 from tilting and bending during rotation, so as to ensure that the circumferential compression amount of the first sealing sleeve 320 remains uniform, and avoiding the sealing failure caused by the clearance 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.
[0076] Therefore, it can be understood that the camera system 1000 of the present invention includes a camera 100 and a wiper assembly 200. The wiper 230 of the wiper assembly 200 can swing along the plane of the window 40 of the camera 100 under the drive of the drive assembly 220, so as to wipe and clean the window 40 when debris adheres to the window 40.
[0077] Meanwhile, a sealing assembly 300 is provided on the second housing 210 which serves as the support base of the wiper assembly 200. A first limiting hole 2111c, a second limiting hole 2111b, and a third limiting hole 2111a which are in communication with each other are successively formed in the second housing 210 from outside to inside. Among them, the second limiting hole 2111b is a flared hole structure with a gradually expanding aperture from the outside to the inside of the second housing 210; the sealing assembly 300 includes a bushing 380 and a first sealing sleeve 320. The bushing 380 is inserted into the first limiting hole 2111c from outside to inside. The first sealing sleeve 320 includes a connected first sealing section 321 and a second sealing section 322. The outer diameter of the first sealing section 321 gradually contracts in a direction away from the second sealing section 322. When the first sealing sleeve 320 is inserted into the second limiting hole 2111b and the third limiting hole 2111a from inside to outside, the first sealing section 321 is inserted into the second limiting hole 2111b, and the second sealing section 322 is inserted into the third limiting hole 2111a. Then, the first sealing pressing plate 340 presses and fixes the first sealing sleeve 320. Under the action of water pressure, the first sealing section 321 deforms from outside to inside to tightly hold the rotating shaft 240, playing a good sealing role; when the rotating shaft 240 of the wiper 230 passes through the bushing 380 and the first sealing sleeve 320, the bushing 380 can fix the position of the rotating shaft 240, while the first sealing sleeve 320 is respectively pressed by the hole walls of the second limiting hole 2111b and the third limiting hole 2111a at the first sealing section 321 and the second sealing section 322, so that the inner wall of the first sealing sleeve 320 presses against and closely adheres to the rotating shaft 240, ensuring that the position and axis of the rotating shaft 240 are stable under the extrusion of the internal first sealing sleeve 320 and the limiting effect of the external bushing 380, effectively avoiding the inclination and bending of the rotating shaft 240 during rotation, thereby avoiding the problem of sealing failure at the rotating shaft 240 caused by uneven circumferential compression of the sealing sleeve, improving the sealing performance of the wiper assembly 200 at the position of the rotating shaft 240, so that the camera system 1000 can be applicable to the underwater environment.
[0078] Please refer to Figures 2 to 6 , in some embodiments of the present application, the camera system 1000 further includes a cable assembly 80. 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 penetrates into the second housing 210 and is connected to the driving assembly 220, and the other end penetrates into the first housing 110 and is electrically connected to the camera 100. One of the SR structures 83 is fixed to the first housing 110, and the other SR structure 83 is fixed to the second housing 210.
[0079] In this embodiment, the wiper assembly 200 and the camera 100 are electrically connected through the cable assembly 80. One end of the cable 81 of the cable assembly 80 is threaded into the second housing 210 and electrically connected to the drive assembly 220, and the other end is threaded into the first housing 110 and connected to the camera 100. It can be connected to a battery provided in the first housing 110, or a device or circuit board 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 setting program of the circuit board or the received signal. In addition, an SR structure 83 can be sleeved outside the cable 81, so that the cable 81 of the SR structure 83 is connected to the first housing 110 and the second housing 210. The setting of the SR structure 83 can eliminate the stress of the cable 81 during swinging, prevent the core wire at the connection position of the cable 81 and the first housing 110 or the second housing 210 from breaking, and can also be used for the clamping and fixing of the cable 81 and the device structural member.
[0080] Please refer to Figure 6 , in some embodiments of the present application, the first housing 110 and the second housing 210 are both provided with insertion holes 135 for threading the SR structure 83;
[0081] A first potting area 85 is formed between the inner wall of the SR structure 83 and the cable 81, and a second potting area 87 is formed between the hole wall of the insertion hole 135 and the outer wall of the SR structure 83.
[0082] In the camera system 1000 proposed by the present application, the wiper assembly 200 and the camera 100 are connected through the cable assembly 80. In order to avoid damage to the cable 81 of the cable assembly 80, the SR structure 83 is provided for connection 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 threaded into the insertion holes 135 of the first housing 110 and the second housing 210. Each SR structure 83 includes two connected segments. One segment of the SR structure 83 close to the outside of the housing 110 is in close fit with the cable 81, and the segment close to the inner cavity of the housing 110 is in clearance fit with the cable 81. Thus, a first potting area 85 is formed between the SR structure 83 and the cable 81, which can be used for pouring 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, avoiding foreign objects from entering the first housing 110 and the second housing 210 between the SR structure 83 and the cable 81.
[0083] Taking the connection between the SR structure 83 and the first housing 110 as an example, the section of the insertion hole 135 close to the outside of the first housing 110 is in close fit with the SR structure 83, and the section of the insertion hole 135 close to the inner cavity of the first housing 110 is in clearance fit with the SR structure 83, that is, a section of the hole wall of the insertion hole 135 is spaced from the SR structure 83 to form a second sealant injection area 87, which can be used for injecting sealant. That is, the bonding effect of the sealant can be used to improve the connection strength between the SR structure 83 and the first housing 110, and can also improve the sealing performance between the SR structure 83 and the hole wall of the insertion hole 135, preventing foreign objects from entering the first housing 110 from between the SR structure 83 and the hole wall of the insertion hole 135. In addition, a sealing ring 360 can be provided between the hole wall of the section of the insertion hole 135 close to the outside of the first housing 110 and the SR structure 83 to further improve the sealing performance between the SR structure 83 and the hole wall of the insertion hole 135. In some embodiments, a peripheral edge 137 surrounding the SR structure 83 can be convexly provided 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 sealant injection area 87, so that more sealant can be injected between the SR structure 83 and the hole wall of the insertion hole 135, further improving the sealing performance. The connection structure between the second housing 210 and the SR structure 83 is similar to the connection structure between the first housing 110 and the SR structure 83, and will not be elaborated here.
[0084] Further, in some embodiments, a locking portion is convexly provided on the side wall 1332 of the end of the SR structure 83 located outside the first housing 110 and the second housing 210. The locking portion is pressed and locked on the outer walls of the first housing 110 and the second housing 210 through locking members such as bolts. With such a setting, when the camera 100 is applied to image acquisition in an underwater environment, under the action of water pressure, the locking portion is subjected to an inward pressure from the outside, so that the locking portion is closely attached to the first housing 110 and the second housing 210, preventing the SR structure 83 from entering the first housing 110 and the second housing 210 under the action of water pressure and causing the sealing failure of the position of the insertion hole 135, so as to improve the sealing performance of the camera system 1000 in the underwater environment.
[0085] Please refer to Figure 2 , in some embodiments of the present application, a first wire groove 136 extending to the bottom surface of the first housing 110 is recessed at one end of the first housing 110 facing away from the lens window 40;
[0086] A second wire groove 2122 extending to the top surface of the second housing 210 is recessed at one end of the second housing 210 facing away from the wiper 230. The second wire groove 2122 is communicated with the first wire groove 136, and part of the cable 81 is embedded in the first wire groove 136 and the second wire groove 2122.
[0087] In the camera system 1000 proposed in this application, the wiper assembly 200 and the camera 100 are connected through the cable assembly 80. In this embodiment, at the rear end of the first housing 110, that is, at one end of the first housing 110 facing away from the fill light window 40 and the lens window 40, a first wire groove 136 is recessed. At the rear end of the second housing 210, that is, at the end facing away from the wiper 230, a second wire groove 2122 is recessed, and the first wire groove 136 and the second wire groove 2122 are made to communicate with each other for embedding the cable 81, so as to limit the cable 81 and prevent the cable 81 from swinging under the action of external force, resulting in the loosening of the connection between the SR structure 83 and the first housing 110 and the second housing 210.
[0088] Please refer to Figure 2 , in some embodiments of this application, the camera 100 further includes a first wire cover 19, and the first wire cover 19 is covered on the first wire groove 136;
[0089] The wiper assembly 200 further includes a second wire cover 216, and the second wire cover 216 is covered on the second wire groove 2122.
[0090] In this embodiment, the first wire cover 19 and the second wire cover 216 are provided to cover the first wire groove 136 and the second wire groove 2122 respectively, so as to hide the cable 81 embedded in the first wire groove 136 and the second wire groove 2122, which can protect the cable 81 and prevent the cable 81 from being directly exposed to the outside, thereby reducing the risk of damage to the cable 81 and preventing the cable 81 from being cut or worn by external objects. Among them, the first wire cover 19 and the first housing 110 can be connected by a buckle 213 or fastened by a bolt, and the second wire cover 216 and the second housing 210 can also be connected by a buckle 213 or fastened by a bolt, which is not specifically limited here.
[0091] Please refer to Figure 3 , in some embodiments of this application, a first connection hole 18 is formed in the bottom wall 1331 of the first housing 110, and a second connection hole 214 is formed in the top wall of the second housing 210, and the first connection hole 18 and the second connection hole 214 are arranged opposite to each other;
[0092] The camera system 1000 further includes a locking member, and the locking member passes through the first connection hole 18 and the second connection hole 214 to connect the camera 100 and the wiper assembly 200.
[0093] It can be understood that the camera system 1000 of the present application is composed of a connected camera 100 and a wiper assembly 200, and the camera 100 is carried on the wiper assembly 200. In this embodiment, the camera 100 and the wiper assembly 200 are fixedly connected by locking members such as bolts. Among them, a first connection hole 18 is opened on the bottom wall 1331 of the first housing 110 of the camera 100, and a second connection hole 214 opposite to the first connection hole 18 is opened on the top wall of the second housing 210 of the wiper 230. It can be such that one of the first connection hole 18 and the second connection hole 214 is a threaded hole, and the locking member is set as a bolt, so that the bolt passes through the first connection hole 18 and the second connection hole 214 and is bolt-connected to the threaded hole therein. It can also be set as a combined connection structure of a bolt and a nut to connect the first housing 110 and the second housing 210 through the bolt, improve the structural stability of the camera system 1000, avoid the deviation of the camera 100 and the wiper assembly 200, and ensure 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 swing process.
[0094] It should be noted that in the technical solution of the present application, the cross-section of the front end portion in the first housing 110 is set to be circular so that the front end portion of the first housing 110 is accommodated in the arc-shaped groove on the top surface of the second housing 210. At this time, if the entire first housing 110 is set as a cylindrical structure, it is difficult to align the first connection hole 18 and the second connection hole 214 when connecting with the second housing 210 because the first housing 110 and the second housing 210 can rotate relative to each other in the circumferential direction. In this embodiment, the bottom surface of the rear end portion of the first housing 110 can be set to be a plane, and the top surface of the rear end portion of the second housing 210 is set to be a plane, so that the first housing 110 and the second housing 210 are circumferentially limited by the abutment of the two planes, which is also beneficial to the alignment of the first connection hole 18 and the second connection hole 214. Of course, the alignment between the first connection hole 18 and the second connection hole 214 can also be assisted by the positioning structure in the following embodiments, which will not be elaborated here.
[0095] Please refer to Figure 3 , in some embodiments of the present application, one of the positioning portion 215 and the positioning hole 3172 is provided on the bottom wall 1331 of the first housing 110, and the other of the positioning portion 215 and the positioning hole 3172 is provided on the top wall of the second housing 210, and the positioning portion 215 is inserted into the positioning hole 3172.
[0096] In the technical solution of the foregoing embodiment, the locking member passes through the relatively arranged and communicating first connection hole 18 and second connection hole 214 to connect and fix the first housing 110 and the second housing 210. In order to accurately align the first connection hole 18 and the second connection hole 214 and keep the wiper assembly 200 and the camera 100 in a fixed relative position, in this embodiment, a positioning portion 215 and a positioning hole 3172 for plug-in cooperation are provided between the first housing 110 and the second housing 210. The positioning portion 215 can be arranged on the bottom wall 1331 of the first housing 110 or on the top wall of the second housing 210, and correspondingly, the positioning hole 3172 is arranged on the top wall of the second housing 210 and the bottom wall 1331 of the first housing 110. When assembling the camera system 1000, only by inserting the positioning portion 215 into the positioning hole 3172 can it be ensured that the camera 100 and the wiper assembly 200 are already aligned, and the swinging 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 connection hole 18 and the second connection hole 214 are already relatively arranged, and only the locking member needs to be passed through for connection and fixation, improving the assembly efficiency of the camera system 1000.
[0097] Please refer to Figure 3 , in some embodiments of the present application, one of the clamping holes 16 and the buckle 213 is provided on the bottom wall 1331 of the first housing 110, and the other of the clamping holes 16 and the buckle 213 is provided on the top wall of the second housing 210, and the buckle 213 is clamped in the clamping hole 16.
[0098] In this embodiment, a buckle 213 and a clamping hole 16 for clamping cooperation are provided between the first housing 110 and the second housing 210. Taking the buckle 213 arranged on the top wall of the second housing 210 and the clamping hole 16 arranged on the bottom wall 1331 of the first housing 110 as an example, the buckle 213 is set to have a structure with a hook at one end, the hook is arranged towards the top wall of the second housing 210, and a clamping portion is convexly provided on the hole wall of the clamping hole 16 or a clamping groove is recessed. When the buckle 213 is inserted into the clamping hole 16, the hook is hooked on the clamping portion or the groove wall of the clamping groove to prevent the buckle 213 from coming out of the clamping hole 16, so as to connect the second housing 210 and the first housing 110. At this time, the camera 100 and the wiper assembly 200 are already aligned, and the swinging 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 connection hole 18 and the second connection hole 214 are already relatively arranged, and only the locking member needs to be passed through for connection and fixation, which can not only improve the assembly efficiency of the camera system 1000, but also the first housing 110 and the second housing 210 are connected and fixed by two methods of buckle 213 connection and bolt connection, and the connection strength between the first housing 110 and the second housing 210 can be improved, and the structural stability of the camera system 1000 can be improved.
[0099] Please refer to Figures 14 to 16 , in some embodiments of the present application, the hole wall inclination angle of the second limiting hole 2111b is greater than the outer wall inclination angle 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 0.2 mm to 0.5 mm.
[0100] In order to make the first sealing section 321 hold the rotating shaft 240 tightly, it is necessary to make the first sealing section 321 have a holding force that holds the rotating shaft 240 tightly along the radial direction of the rotating shaft 240. In this embodiment, the outer wall inclination angle of the first sealing section 321 is made smaller than the hole wall inclination angle of the second limiting hole 2111b. With such a setting, when the first sealing section 321 is squeezed by the hole wall of the second limiting hole 2111b, the second limiting hole 2111b applies force to the first sealing section 321 in both the axial and radial directions of the rotating shaft 240 at the same time, so that the first sealing section 321 can deform from the outside to the inside and hold the rotating shaft 240 tightly.
[0101] In addition, when the first sealing section 321 is squeezed by the hole wall of the second limiting hole 2111b, the outer wall compression amount of the first sealing section 321 is limited to be between 0.5 mm and 1.2 mm, which can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 09 mm, 1.0 mm, 1.1 mm, 1.2 mm or any value between 0.5 mm and 1.2 mm, and is not limited herein; with such a setting, it can be ensured that the first sealing section 321 fully adheres to the hole wall of the second limiting hole 2111b, ensuring good sealing performance between the first sealing sleeve 320 and the through hole 2111, and effectively isolating foreign substances from entering the second housing 210.
[0102] In some embodiments, a limiting portion surrounding the first sealing section 321 is provided on the end surface of the second sealing section 322 close to the first sealing section 321. The aperture of the third limiting hole 2111a is larger than the maximum aperture of the second limiting hole 2111b, so as to form a limiting step surrounding the second limiting hole 2111b 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 section 321 and the hole wall of the second limiting hole 2111b can be restricted, so that the compression amount of the first sealing section 321 is within a preset compression amount range.
[0103] Please refer to Figure 16 and Figure 20, in some embodiments of the present application, at least two sealing lips 326 are convexly provided on the inner wall of the first sealing sleeve 320 and are arranged at intervals along the axial direction of the rotating shaft 240. Each sealing lip 326 encloses a through hole for the rotating shaft 240 to pass through, and the aperture of the through hole gradually increases from outside to inside, so that the sealing lip 326 can deform from outside to inside and tightly hold the rotating shaft 240.
[0104] In this embodiment, at least two sealing lips 326 are convexly provided on the inner wall of the first sealing sleeve 320. The sealing lips 326 extend from inside to outside and gradually approach the rotating shaft 240 until the end of the sealing lip 326 fits against the surface of the rotating shaft 240. At this time, each sealing lip 326 is circumferentially arranged around 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 outside to inside. With such a setting, when the sealing lip 326 receives an external pressure such as water pressure, the sealing lip 326 deforms into the second housing 210 and tightly holds the rotating shaft 240 to play a good sealing role and prevent foreign objects from entering the second housing 210. The setting of the through hole enables the sealing lip 326 to avoid being subjected to a large resistance when deforming. It can be understood that the setting of at least two sealing lips 326 can form a multi-stage barrier sealing effect and effectively improve the sealing performance. In some embodiments, it can be such that the sealing lip 326 is convexly provided on the inner wall of the second sealing section 322. When the sealing lip 326 closest to the wiper 230 in the second sealing section 322 extends outward, the first sealing section 321 is formed.
[0105] In some embodiments of the present application, the compression amount when the sealing lip 326 is in extrusion fit with the rotating shaft 240 is 0.5 mm to 1.2 mm.
[0106] 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 receives an external force from outside to inside, the sealing lip 326 undergoes elastic compression to closely adhere to the rotating shaft 240. At this time, the compression amount of the sealing lip 326 is between 0.5 mm and 1.2 mm, which can be 0.5 mm, 0.6 mm, 0.7 mm, 0.8 mm, 0.9 mm, 1.0 mm, 1.1 mm, 1.2 mm or any value between 0.5 mm and 1.2 mm, which is not limited herein; with such a setting, it can be ensured that the sealing lip 326 tightly holds and adheres to the rotating shaft 240, ensuring good sealing performance between the first sealing sleeve 320 and the rotating shaft 240 and effectively isolating foreign objects from entering the second housing 210.
[0107] Please refer to Figure 16 , in some embodiments of the present application, a first crimping rib 324 is convexly provided on the outer wall of the second sealing section 322. The first crimping rib 324 is circumferentially arranged around the first sealing sleeve 320 and is in extrusion fit with the hole wall of the third limiting hole 2111a.
[0108] In this embodiment, a first crimping rib 324 protrudes from the outer wall of the second sealing section 322. The first crimping rib 324 is arranged around the second sealing section 322. When the first sealing sleeve 320 is inserted into the through hole 2111, the first crimping rib 324 is squeezed and fitted with the wall of the third limiting hole 2111a. Such a setting is to increase the local outer diameter of the second sealing section 322 through the first crimping rib 324, so that the second sealing section 322 can fully block between the third limiting hole 2111a and the rotating shaft 240, increase the compression amount of the second sealing section 322, improve the sealing performance, and avoid the difficulty of inserting the first sealing sleeve 320 into the through hole 2111 due to the increase of the outer diameter of the whole section of the second sealing section 322. Among them, at least two first crimping ribs 324 can be provided, and at least two first crimping ribs 324 are arranged in sequence along the axial direction of the rotating shaft 240, so as to play a role of multi-stage sealing and improve the sealing performance.
[0109] Please refer to Figure 16 , in some embodiments of the present application, a crimping portion 323 protrudes from the outer wall of the end of the second sealing section 322 away from the first sealing section 321. The crimping portion 323 is arranged around the circumference of the first sealing sleeve 320;
[0110] A second crimping rib 325 protrudes from the inner wall of the crimping portion 323 facing the second housing 210. The first sealing pressing plate 340 presses the crimping portion 323 so that the second crimping rib 325 is squeezed and abutted against the inner wall of the second housing 210.
[0111] In the technical solution of the foregoing embodiment, the first sealing sleeve 320 is pressed in the through hole 2111 by the first sealing pressing plate 340 fixed to the inner wall of the second housing 210. In this embodiment, a crimping portion 323 protrudes from the side wall 1332 of the end of the second sealing section 322 away from the first sealing section 321. The crimping portion 323 is located outside the through hole 2111 and is clamped between the first sealing pressing plate 340 and the inner wall of the second housing 210. Such a setting can limit the insertion depth of the first sealing sleeve 320 through the crimping portion 323, avoid the first sealing sleeve 320 from completely entering the inside of the through hole 2111, and make the compression portion be clamped to prevent the first sealing sleeve 320 from rotating with the rotating shaft 240. It can also limit the compression amount between the first sealing section 321 and the wall of the second limiting hole 2111b.
[0112] Further, a second crimping rib 325 protrudes from the surface of the compression part facing the inner wall of the second housing 210. The second crimping rib 325 is arranged in a circumferential direction around the rotating shaft 240, so that the second crimping rib 325 is in pressing fit with the inner wall of the second housing 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 objects from entering the second housing 210 between the first sealing sleeve 320 and the through hole 2111.

The locking member sequentially passes through the first locking hole and the second locking hole from the inside to the outside of the second housing 210 to lock the first sealing pressing plate 340 to the inner wall of the second housing 210.
[0114] In this embodiment, the first sealing pressing plate 340 is locked to the inner wall of the second housing 210 by a locking member such as a bolt. Among them, a first locking hole is provided on the first sealing pressing plate 340, the first locking hole is a through hole, a second locking hole is provided on the inner wall of the second housing 210, the second locking hole is a threaded hole and a blind hole, the locking member is set as a bolt, and the locking member passes through the first locking hole from the side of the first sealing pressing plate 340 facing away from the first sealing sleeve 320 and is inserted into the second locking hole to be threadedly connected with the second locking hole, so as to lock the first sealing pressing plate 340 to the inner wall of the second housing 210, so that the first sealing pressing plate 340 is subjected to a pressure from the inside to the outside to press the first sealing sleeve 320.
[0115] In some embodiments, an extension portion 2115 protrudes from the inner wall of the second housing 210, and the through hole 2111 penetrates through the extension portion 2115 to prevent the depth of the through hole 2111 from being limited by the wall thickness of the second housing 210, so that the through hole 2111 has sufficient length for installing the bushing 380 and the first sealing sleeve 320. At this time, the first sealing pressing plate 340 is pressed against the end face of the extension portion 2115.
[0116] Please refer to Figure 15 , in some embodiments of the present application, the sealing assembly 300 further includes:
[0117] A sealing bracket 310, the sealing bracket 310 forms a cylindrical structure with one end open, the opening of the sealing bracket 310 covers the inner wall of the second housing 210, so that a sealing space is formed inside the sealing bracket 310, and an installation hole 311 is provided at the end of the sealing bracket 310 facing away from the wiper 230; and
[0118] The second seal sleeve 330 is inserted into the mounting hole 311. The rotating shaft 240 passes through the second seal sleeve 330 and elastically presses the second seal sleeve 330 between the rotating shaft 240 and the hole wall of the mounting hole 311.
[0119] In this embodiment, the sealing assembly 300 further includes a sealing bracket 310 and a second seal sleeve 330. The sealing bracket 310 is a cylindrical structure with an open end. The cross-sectional shape of the sealing bracket 310 can be polygonal, circular, or other regular or irregular shapes, which is not limited here. The sealing bracket 310 is fixed to the inner wall of the second housing 210, so that the inner wall of the second housing 210 with the through hole 2111 seals the opening of the sealing bracket 310 to form a sealed space inside the sealing bracket 310. At the same time, a mounting hole 311 for passing through the rotating shaft 240 is opened on the bottom wall 1331 of the cylinder of the sealing bracket 310 opposite to the inner wall of the second housing 210. The second seal sleeve 330 is inserted into the mounting hole 311 and sleeved on the rotating shaft 240. The second seal sleeve 330 is made of an elastic material such as silica gel or rubber. When it is clamped between the hole wall of the mounting hole 311 and the rotating shaft 240, the second seal sleeve 330 undergoes compressive deformation, so that the second seal sleeve 330 closely adheres to the hole wall of the mounting hole 311 and the outer surface of the rotating shaft 240, effectively blocking the gap between the hole wall of the mounting hole 311 and the rotating shaft 240, playing a good sealing role and avoiding damaging the sealing performance of the sealed space. With such a setting, the rotating shaft 240 passes through the first seal sleeve 320, the sealing bracket 310, and the second seal sleeve 330 in sequence to form multiple-stage seals axially from the inside to the outside along the rotating shaft 240 in the second housing 210, effectively improving the sealing performance of the position of the rotating shaft 240 and preventing foreign objects from entering the second housing 210 along the rotating shaft 240.

At least one second seal sleeve 330 is provided in each sealing groove, so that at least two-stage seals can be formed at the mounting hole 311 to improve the sealing performance of the sealing bracket 310. The setting of the sealing ring can also play a role in limiting the rotating shaft 240, keeping the central axis of the rotating shaft 240 in a stable position, thereby preventing the rotating shaft 240 from tilting during rotation and making the circumferential compression amounts of the first seal sleeve 320 and the second seal sleeve 330 uniform.

The second fixing hole 2112 can be set as a threaded hole and a blind hole, and a bolt is used as the locking member, so that the locking member passes through the first fixing hole 3171 and is threadedly connected to the second fixing hole 2112 to fix the sealing bracket 310 on the inner wall of the second housing 210. At this time, the locking member presses the sealing bracket 310 against the inner wall of the housing 110 from the inside outwards, which is more beneficial to improving the sealing performance of the sealing bracket 310.
[0123] Please refer to Figure 19 and Figure 21 , one of a positioning hole 3172 and a positioning post 2113 is provided on the surface of the fixing ear 317 facing the inner wall of the housing assembly, and the other of the positioning hole 3172 and the positioning post 2113 is provided on the inner wall of the second housing 210, and the positioning post 2113 is inserted into the positioning hole 3172.

Among them, the second sealing pressure plate 370 can be arranged inside the sealing bracket 310, outside the sealing bracket 310, or second sealing pressure plates 370 can be arranged at both ends of the mounting hole 311 at the same time. The rotating shaft 240 is in clearance fit with the second sealing pressure plate 370. The arrangement of the second sealing pressure plate 370 can both limit the rotating shaft 240 to prevent the rotating shaft 240 from tilting and bending during rotation, so as to ensure that the circumferential compression amounts of the first sealing sleeve 320 and the second sealing sleeve 330 are uniform and avoid the problem of sealing failure. At the same time, the second sealing pressure plate 370 can prevent the second sealing sleeve 330 from coming out of the mounting hole 311, improve the position stability of the second sealing sleeve 330, and ensure the sealing effect of the second sealing sleeve 330 on the mounting hole 311.
[0127] Please refer to Figure 17 , in some embodiments of the present application, the second sealing sleeve 330 includes:

The seal section 3321 extends from the connection with the outer mounting sleeve 331 toward the rotating shaft 240 from outside to inside. The limiting section 3322 extends from the end of the seal section 3321 from outside to inside away from the rotating shaft 240, so that a limiting groove 3323 is formed between the seal section 3321 and the limiting section 3322. At the same time, a circular spring 350 is sleeved on the first seal lip 332 and the circular spring 350 is limited in the limiting groove 3323. With this setting, the circular spring 350 is in an elastically expanded state, and the circular spring 350 has an elastic force that contracts inward and is applied to the first seal lip 332 to hold the rotating shaft 240 tightly, improving the sealing performance between the second seal sleeve 330 and the rotating shaft 240; and the circular spring 350 is limited in the limiting groove 3323, which can prevent the circular spring 350 from coming off the first seal lip 332.

[0149] Please refer to Figures 4 to 6 , in some embodiments of the present application, the first housing 110 includes a seal 15 and a front housing 11 and a rear housing 13 that are covered with each other. The front housing 11 is provided with a window 40; one of a plug-in portion 111 and a plug-in groove 131 is provided on the end face of the front housing 11 facing the rear housing 13, and the other of the plug-in portion 111 and the plug-in groove 131 is provided on the end face of the rear housing 13 facing the front housing 11. The plug-in portion 111 and the plug-in groove 131 are both arranged around the circumference of the installation cavity, and the plug-in portion 111 is inserted into the plug-in groove 131; the seal 15 includes a first seal portion 151 and a second seal portion 152. At least one of the two groove side walls 1332 of the plug-in groove 131 and the plug-in portion 111 is clamped with the first seal portion 151, and the second seal portion 152 is clamped between the groove bottom wall 1331 of the plug-in groove 131 and the plug-in portion 111.
[0150] In this embodiment, the first housing 110 of the camera 100 is configured as a combined structure of a front housing 11 and a rear housing 13, and the front housing 11 and the rear housing 13 are connected to each other through the plug-in relationship between the plug-in portion 111 and the plug-in groove 131. With such a setting, when the front housing 11 and the rear housing 13 are deformed under pressure, at least one groove side wall 1332 of the plug-in groove 131 will abut against the plug-in portion 111, thereby reducing the generation of the gap between the front housing 11 and the rear housing 13; further, a seal 15 is provided in the plug-in groove 131. The seal 15 includes a first sealing portion 151 and a second sealing portion 152. The first sealing portion 151 is clamped between the groove side wall 1332 of the plug-in groove 131 and the plug-in portion 111. The first sealing portion 151 can be set at the corresponding position in advance according to the relationship between the external pressure at the detection position of the camera 100 and the internal pressure of the camera 100. For example, when the external pressure at the target detection position is greater than the internal pressure of the camera 100, the first sealing portion 151 is set between the outer groove side wall 1332 and the plug-in portion 111. With such a setting, the front housing 11 and the rear housing 13 are subjected to pressure towards the inside of the housing 110 and deform inwards. At this time, the outer lateral compression can be realized through the first sealing portion 151, thereby making up for the problem of insufficient inner lateral compression; when the external pressure at the target detection position is less than the internal pressure of the camera 100, the first sealing portion 151 is set between the inner groove side wall 1332 and the plug-in portion 111 to make up for the problem of insufficient outer lateral compression; of course, the first sealing portion 151 can also be provided between the two groove side walls 1332 of the plug-in groove 131 and the plug-in portion 111 to improve the use convenience and applicability. The second sealing portion 152 is clamped between the groove bottom wall 1331 of the plug-in groove 131 and the plug-in portion 111, and can withstand the pressure in the arrangement direction of the front housing 11 and the rear housing 13, effectively playing a role in water stopping.
[0151] In some embodiments, an encapsulating portion surrounding the first housing 110 is further provided outside the connection position of the front housing 11 and the rear housing 13. An encapsulating cavity 139 is formed in the encapsulating portion, which can be used for pouring sealant, which can not only enhance the sealing performance, but also play a buffering role, reduce the pressure on the first housing 110, reduce the deformation of the front housing 11 and the rear housing 13 at the connection position, and improve the sealing performance.
[0152] Please refer to Figure 5 , in some embodiments of the present application, a glue-containing wall 113 protrudes from the outer wall of the front housing 11. The glue-containing wall 113 is arranged around the circumference of the front housing 11 and extends towards the rear housing 13;
[0153] The outer wall of the rear shell 13 is convexly provided with a sealing wall 133. The sealing wall 133 is arranged around the circumference of the rear shell 13 and extends forward to the front shell 11 to dock with the glue-containing wall 113, so as to enclose a glue injection 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 injection port 1333 communicating with the glue injection cavity 139.
[0154] In some embodiments, the glue-containing wall 113 extends across the connection position of the front shell 11 and the rear shell 13 to the rear shell 13. Such a setting is to ensure that when glue is injected through the glue injection port 1333 on the sealing wall 133 of the rear shell 13, the glue in the glue injection cavity 139 can fully cover the outside of the connection position of the front shell 11 and the rear shell 13.
[0155] One of the convex portion 115 and the groove 134 is provided on the end face of the glue-containing wall 113 facing the sealing wall 133, and the other of the convex portion 115 and the groove 134 is provided on the end face of the sealing wall 133 facing the glue-containing wall 113. The convex portion 115 and the groove 134 are both arranged around the circumference of the installation cavity. The convex portion 115 is inserted into the groove 134. Such a setting makes a plurality of bending paths formed at the connection position between the glue-containing wall 113 and the sealing wall 133, increasing the difficulty of the sealing glue overflowing from the connection position between the glue-containing wall 113 and the sealing wall 133, and avoiding the sealing glue from overflowing outward from the connection position between the glue-containing wall 113 and the sealing wall 133.
[0156] Please refer to Figure 6 , in some embodiments of the present application, a first convex rib 155 is convexly provided on the surface of the first sealing portion 151 facing the corresponding groove side wall 1332. The first convex rib 155 is arranged around the circumference of the installation cavity and abuts against the groove side wall 1332.
[0157] In the technical solution of the present application, by sandwiching the first sealing portion 151 of the seal 15 between the groove side wall 1332 of the insertion groove 131 and the insertion portion 111, the problem of insufficient compression on the outside or inside when the first housing 110 is pressed is compensated, so that the groove side wall 1332 of the insertion groove 131 and the insertion portion 111 are blocked by the first sealing portion 151. In this embodiment, a first convex rib 155 is convexly provided on the surface of the first sealing portion 151 facing its corresponding groove side wall 1332. At this time, the first convex rib 155 is arranged around the circumference of the first housing 110 along with the first sealing portion 151, so that the first convex rib 155 abuts against the groove side wall 1332 and generates elastic compression. Such a setting is to increase the thickness of the first sealing portion 151 at the position of the first convex rib 155, so that the compression amount at this place is larger, and it can better fit the groove side wall 1332 to block the gap between the groove side wall 1332 and the insertion portion 111, improving the sealing performance.
[0158] Please refer to Figure 6, in some embodiments of the present application, a second rib 157 protrudes from the surface of the second sealing portion 152 facing the bottom wall 1331 of the groove. The second rib 157 is arranged to surround the circumferential direction of the installation cavity and abuts against the bottom wall 1331 of the groove.
[0159] Similarly, the second sealing portion 152 is used to bear the pressure of the first housing 110 in the front - rear direction and generate corresponding compressive deformation to play a better sealing role. In this embodiment, a second rib 157 protrudes from the surface of the second sealing portion 152 facing the bottom wall 1331 of the groove, increasing the thickness and compression amount of the second sealing portion 152 at the position where the second rib 157 is provided. Thus, when the front housing 11 and the rear housing 13 are subjected to pressure in the front - rear direction and the deformation amounts of the front housing 11 and the rear housing 13 are not equal, the insufficiently compressed part can be compensated by the second sealing portion 152, and the second sealing portion 152 is closely attached to the plug - in portion 111 and the bottom wall 1331 of the plug - in groove 131, improving the sealing performance.
[0160] Please refer to Figure 6 , in some embodiments of the present application, a fitting protrusion 159 protrudes from the surface of the second sealing portion 152 facing the plug - in portion 111, and the fitting protrusion 159 is embedded in the plug - in portion 111.
[0161] In this embodiment, a fitting protrusion 159 protrudes from the surface of the second sealing portion 152 facing the plug - in portion 111 and is embedded in the plug - in portion 111, so that the seal 15 is fixedly connected to the plug - in portion 111, which can improve the position stability of the seal 15 and prevent the seal 15 from being displaced and causing sealing failure.
[0162] Please refer to Figure 5 , in some embodiments of the present application, the glue - containing wall 113 extends to the rear housing 13.
[0163] It can be understood that in the present application, the potting portion needs to cover the outside of the connection position of the front housing 11 and the rear housing 13 to improve the sealing performance at the connection position of the front housing 11 and the rear housing 13, and the potting port 1333 of the potting portion is opened on the sealing wall 133 of the rear housing 13. In this embodiment, the glue - containing wall 113 extends across the connection position of the front housing 11 and the rear housing 13 to the side of the rear housing 13. With this setting, when the end face of the front housing 11 is placed on the bearing surface for potting, it can ensure that the poured glue submerges the connection position of the front housing 11 and the rear housing 13, so as to ensure that there is a protective layer formed by the sealing glue outside the connection position of the front housing 11 and the rear housing 13, thus ensuring that the setting of the potting portion can play the expected protection and buffering roles.
[0164] Please refer to Figure 12 and Figure 13, in some embodiments of the present application, the sealing wall 133 is provided with an exhaust port 1334 communicating with the potting cavity 139, and the exhaust port 1334 and the potting port 1333 are arranged at intervals along the circumferential direction of the installation cavity.
[0165] In the technical solution of the foregoing embodiment, after the front shell 11 and the rear shell 13 are assembled, a potting part is naturally formed on the outside of the connection position, and the potting port 1333 of the potting part is opened on the sealing wall of the rear shell 13. It can be understood that in order to avoid glue leakage, the sealing performance of the potting cavity 139 is relatively good. In this embodiment, an exhaust port 1334 communicating with the potting cavity 139 is opened on the sealing wall 133. With this setting, the air in the potting cavity 139 can be discharged outward while potting the potting cavity 139, avoiding the influence of the gas in the potting cavity 139 on potting.
[0166] Please refer to Figure 12 , in some embodiments of the present application, the sealing wall 133 includes a connected bottom wall 1331 and a side wall 1332. The bottom wall 1331 protrudes from the outer wall of the rear shell 13, and the side wall 1332 extends from the bottom wall 1331 toward the front shell 11. At least two potting ports 1333 are opened on the surface of the bottom wall 1331 facing away from the front shell 11, and the at least two potting ports 1333 are arranged at intervals along the circumferential direction of the installation cavity. An overflow groove 1336 is also opened on the surface of the bottom wall 1331 facing away from the front shell 11, and both ends of the overflow groove 1336 are respectively communicated with two adjacent potting ports 1333.
[0167] In this embodiment, the sealing wall 133 includes a bottom wall 1331 and a side wall 1332. The bottom wall 1331 is substantially parallel to the front end face of the front shell 11 and is provided with a potting port 1333. With this setting, when the front end face is placed on the bearing surface, the potting port 1333 is arranged upward, so as to facilitate the user to inject glue into the potting cavity 139. At the same time, an overflow groove 1336 is opened on the surface of the bottom wall 1331 facing away from the potting cavity 139, and at least two potting ports 1333 are arranged along the circumferential direction on the bottom wall 1331. Both ends of the overflow groove 1336 are respectively communicated with the two potting ports 1333. With this setting, when the glue overflows from one of the potting ports 1333, the overflowed glue can flow along the overflow groove 1336 to the other potting port 1333, so that the glue level in the potting cavity 139 is kept consistent along the circumference of the rear shell 13, avoiding uneven distribution of glue in the potting cavity 139.
[0168] In some embodiments, a processing step is convexly provided on the surface of the bottom wall 1331 facing away from the potting cavity 139. At this time, the surface flush with the potting port 1333 forms an overflow surface 1335, and an overflow groove 1336 is opened on the step surface higher than the overflow surface 1335, so as to ensure that the glue can fill the potting cavity 139 until it overflows onto the overflow surface 1335.
[0169] Please refer toFigure 5 and Figure 10 In some embodiments of the present application, the first housing 110 further includes a glue shielding ring 17, and the glue shielding ring 17 covers the outer wall of the rear housing 13 and shields the glue injection port 1333.
[0170] In this embodiment, the first housing 110 further includes a glue shielding ring 17. After the glue injection cavity 139 is filled with glue, the glue shielding ring 17 can be used to cover the outside of the sealing wall 133 and seal the glue injection port 1333, preventing the glue injection port 1333 from being exposed to the outside and causing the glue to overflow from the glue injection port 1333, and also preventing foreign objects from entering the glue injection cavity 139 from the glue injection port 1333. In some embodiments, the camera 100 is applied to an underwater environment. At this time, it can prevent the glue injection port 1333 from being exposed, resulting in direct contact between the sealant in the glue injection cavity 139 and water, which speeds up the failure of the sealant, thereby ensuring the storage life of the sealant.
[0171] Please refer to Figure 8 and Figure 11 In some embodiments of the present application, the front housing 11 is provided with an installation opening 119 communicating with the outside and the installation cavity. The window 40 includes a window main body 41 and a stop portion 43. Part of the window main body 41 is inserted into the installation opening 119, and a stop portion 43 surrounding the window main body 41 is convexly provided on the side surface of the window main body 41 located in the installation cavity;
[0172] The camera 100 further includes:
[0173] A window pressing cover 50, the window pressing cover 50 presses the stop portion 43, and the window pressing cover 50 is provided with an avoidance hole 51 for exposing the window main body 41; and
[0174] A first sealing ring 60, the first sealing ring 60 is clamped between the stop portion 43 and the inner wall of the front housing 11 and is arranged in a circumferential direction around the window 40.
[0175] In the camera 100, a transparent window 40 for light transmission is provided on the end face of the front shell 11. It is possible to only provide the lens window 40, or to provide the fill light window 40 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 an installation opening 119. The window 40 includes a window body 41 and a stop portion 43 protruding from the rear side wall 1332 of the window body 41, so that the window body 41 is inserted into the installation opening 119 from the inside out. The stop portion 43 abuts against the inner wall of the first housing 110 to limit the installation position of the window 40 and prevent the window 40 from disengaging from the installation opening 119. At the same time, a window gland 50 is provided. The window gland 50 is connected and fixed to the inner wall of the first housing 110 and presses on the stop portion 43 to fix the window 40. At the same time, an avoidance hole 51 is provided on the window gland 50 opposite to the window body 41, so that the lens assembly 30 or the fill light 90 is arranged toward the window body 41 from the avoidance hole 51.
[0176] In this embodiment, a first sealing ring 60 is clamped between the stop portion 43 and the inner wall of the first housing 110. The first sealing ring 60 is made of an elastic material such as silica gel or rubber. When the stop portion 43 is tightly pressed against the inner wall of the first housing 110 by the window gland 50, the first sealing ring 60 is compressed and deformed to closely adhere to the stop portion 43 and the inner wall of the first housing 110, thereby filling the gap between the stop portion 43 and the inner wall of the first housing 110, playing a sealing role, preventing foreign objects from entering the first housing 110 from the window 40 area, improving the sealing performance of the camera 100, enabling the camera 100 to be applicable to underwater environments or other similar environments, and improving the applicability of the camera 100.
[0177] Please refer to Figure 8 , in some embodiments of the present application, a first sealing rib 61 protrudes from the surface of the first sealing ring 60 facing the inner wall of the front shell 11. A sealing groove is provided on the inner wall of the front shell 11. Both the first sealing rib 61 and the sealing groove are arranged in a circumferential direction around the window 40, and the first sealing rib 61 is embedded in the sealing groove.
[0178] In this embodiment, a first sealing pressing rib protrudes from the surface of the first sealing ring 60 facing the inner wall of the first housing 110 to increase the thickness of the first sealing ring 60. And the first sealing pressing rib is elastically compressed under the pressing of the inner wall of the first housing 110, so that the first sealing ring 60 better closely adheres to the inner wall of the first housing 110, thereby improving the sealing performance between the stop portion 43 of the window 40 and the inner wall of the first housing 110 and preventing foreign objects from flowing into the first housing 110.
[0179] Please refer to Figure 8, in some embodiments of the present application, a second sealing rib 62 is convexly provided on the surface of the first sealing ring 60 facing the stopper 43. The second sealing rib 62 is arranged to surround the circumference of the window 40 and abuts against the window gland 50.
[0180] In this embodiment, a second sealing rib 62 is convexly provided on the surface of the first sealing ring 60 facing the stopper 43 to increase the thickness of the first sealing ring 60. And the second sealing rib 62 is elastically compressed under the pressing of the stopper 43, so that the first sealing ring 60 can better fit tightly with the stopper 43, thereby improving the sealing performance between the stopper 43 of the window 40 and the inner wall of the first housing 110, and preventing foreign substances from flowing into the first housing 110 from the outside.
[0181] Please refer to Figure 8 and Figure 10 , in some embodiments of the present application, the camera 100 further includes a second sealing ring 70. The second sealing ring 70 is clamped between the window gland 50 and the stopper 43 and is arranged to surround the circumference of the window 40.
[0182] In this embodiment, a second sealing ring 70 is provided between the window gland 50 and the stopper 43 to form a closed area between the inner surface of the window 40, the relief hole 51 of the window gland 50, and the supplementary light 90 or the lens assembly 30, preventing foreign objects or moisture from entering the closed area, which may cause the inner surface of the window 40 to be contaminated with foreign objects or fogged, 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 clamped between the stopper 43 and the window gland 50. The connecting portion is convexly provided on the inner ring 361 of the sealing portion and is inserted into the relief hole 51 to fit with the hole wall of the relief hole 51, improving the connection strength between the second sealing ring 70 and the window gland 50 and the window 40, and limiting the second sealing ring 70 to prevent the problem of the second sealing ring 70 being displaced and blocking the window 40.
[0183] Please refer to Figure 8 , in some embodiments of the present application, a glue-blocking ring 117 is convexly provided on the inner wall of the front shell 11 and is arranged to surround the window 40. The glue-blocking ring 117 is spaced from the side wall 1332 of the stopper 43 to form a glue-filling space.
[0184] 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 between the glue-blocking ring 117 and the side wall 1332 of the window 40. Sealant can be poured into the glue-filling space, which can not only improve the connection strength between the window 40 and the first 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 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 first shell 110 from the window 40 area.
[0185] Please refer to Figure 14 In some embodiments of the present application, the second shell 210 includes a front cover 211 and a rear cover 212 that cover each other, the front cover 211 is provided with a through hole 2111, and the outer side wall 1332 of the front cover 211 is provided with a second glue-containing wall 2118, which is arranged around the circumference of the front cover 211 and extends to the rear cover 212; the outer wall of the rear cover 212 is provided with a second sealing wall 2123, which is arranged around the circumference of the rear cover 212 and extends toward the front cover 211 and connects with the second glue-containing wall 2118, so as to enclose a second glue-filling cavity 217 with the second glue-filling wall 2118, the outer wall of the front shell 11 and the outer wall of the rear shell 13, and the second sealing wall 2123 is provided with a second glue-filling port 2124 that communicates with the second glue-filling cavity 217.
[0186] In this way, a glue pouring portion is provided around the second shell 210 on the outside of the connection position between the front cover 211 and the rear cover 212, and a second glue pouring cavity 217 is formed in the glue pouring portion, which can be used to pour sealant, which can not only enhance the sealing performance, but also play a buffering role, reduce the pressure on the second shell 210, reduce the deformation of the front cover 211 and the rear cover 212 at the connection position, and improve the sealing performance.
[0187] Please refer to Figures 22 to 25 In some embodiments of the present application, the camera system 1000 further includes a sensor assembly 400 , and an external wire 430 of the sensor assembly 400 extends to the outside of the camera 100 and is connected to the cable 81 to be electrically connected to the camera 100 .
[0188] In this embodiment, the camera system 1000 also includes a sensor component 400, so that the external line of the sensor component 400 extends to the position of the camera 100 and is connected to the cable 81 of the cable component 80 so that the sensor is electrically connected to the camera 100. In this way, the sensor component 400 can be powered by the camera 100 or the sensed information can be transmitted to the camera 100.
[0189] Among them, the sensor assembly 400 can be fixedly connected to the camera 100 or the wiper assembly 200, and there is no limitation here.
[0190] Please refer to Figure 22 and Figure 23 In some embodiments of the present application, the sensor assembly 400 includes a mounting base 411, a first sensor 412, and a buffer pad 413. The mounting base 411 includes a base body and a gland. The base body is fixed to the first housing 110 and forms a mounting groove 315. The first sensor 412 is carried in the mounting groove 315 and is fixed by pressing with the gland. The buffer pad 413 is sleeved on the first sensor 412 and is clamped between the first sensor 412 and the base body and the gland, playing a protective role for the first sensor 412 to prevent the first sensor 412 from directly abutting against the base body and the gland and being worn.
[0191] Please refer to Figure 24 and Figure 25 In some embodiments of the present application, the sensor assembly 400 includes a sensor bracket 421, a second sensor 422, a sensor front cover 423, and a retaining ring 424. The sensor bracket 421 includes two oppositely arranged mounting portions and a bottom plate disposed between the two mounting portions and connected to the two mounting portions. The bottom plate extends outward from the two mounting portions for connection with the second housing 210. The second sensor 422 passes through the two mounting portions. The front end of the second sensor 422 is covered with a sensor front cover 423, and the rear end of the second sensor 422 is sleeved with a retaining ring 424, so that the two mounting portions are clamped between the sensor front cover 423 and the retaining ring 424, thereby fixing the second sensor 422 to the sensor bracket 421.
[0192] Refer to Figure 15 and Figure 16 The present application also provides a camera system 1000, which includes:
[0193] A camera 100, the camera 100 includes a first housing 110 and a lens assembly 30 disposed in the first housing 110. A window 40 for transmitting light is provided on the end face of the first housing 110;
[0194] A wiper assembly 200, the wiper assembly 200 includes a second housing 210, a driving assembly 220, and a wiper 230. The top end of the second housing 210 supports the first housing 110. The cable 81 extending out of the second housing 210 extends into the first housing 110 and is electrically connected to the camera 100. Among them, the driving assembly 220 includes a rotating shaft 240 having an axis, and the axis is parallel to the optical axis of the camera 100. The middle part of the rotating shaft 240 extends out of the front end face of the second housing 210 and is then fixedly connected to the wiper 230 to drive the wiper 230 to swing against the window 40;
[0195] Among them, the front end face of the second housing 210 includes a through hole 2111 extending along the axis. The through hole 2111 sequentially includes a second limiting hole 2111b and a third limiting hole 2111a. The second limiting hole 2111b and the third limiting hole 2111a are circular in a cross-section perpendicular to the axis. The cross-sectional radius of the second limiting hole 2111b increases along the extension direction of the axis.
[0196] The first sealing sleeve 320 includes a first sealing section 321 and a second sealing section 322. The outer surface of the first sealing section 321 is trumpet-shaped, and a first crimping rib 324 is provided on the outer surface of the second sealing section 322.
[0197] Among them, the first sealing sleeve 320 is defined as follows: after the rotating shaft 240 sequentially passes through the first sealing sleeve 320, the through hole 2111 and is fastened to the wiper 230, the second limiting hole 2111b of the through hole 2111 accommodates the first sealing section 321 and the third limiting hole 2111a accommodates the second sealing section 322. The minimum radius of the first sealing section 321 is greater than the minimum radius of the second limiting hole 2111b, and the radius of the protrusion of the second sealing section 322 is greater than the maximum radius of the third limiting hole 2111a, so that the outer surface of the first sealing sleeve 320 and the inner surface of the through hole 2111 are sequentially subjected to a first radial force formed by the second limiting hole 2111b and the first sealing section 321 and a second radial force formed by the third limiting hole 2111a and the second sealing section 322, thereby forming a sealed cavity inside the second housing 210.
[0198] The camera system 1000 proposed in this embodiment mainly includes a camera 100 and a wiper assembly 200. The camera 100, as the main functional component for image acquisition, includes a first housing 110 as the bearing base, a supplementary light 90 and a lens assembly 30 disposed within the first housing 110. It is defined that the camera 100 has a front-back direction, and the front end of the camera 100 is oriented towards the position to be observed. A viewing window 40 is provided on the front end face of the first housing 110. It can be only the lens viewing window 40, and in some embodiments, a supplementary light viewing window 40 and a lens viewing window 40 can also be provided simultaneously. The supplementary light 90 within the first housing 110 is oriented towards the supplementary light viewing window 40, and the lens assembly 30 is oriented towards the lens viewing window 40. Thus, the lens assembly 30 can collect image information of the position to be observed through the lens viewing window 40, and the light emitted by the supplementary light 90 can be emitted forward through the supplementary light viewing window 40 to increase the brightness of the position to be observed, making the image collected by the lens assembly 30 clearer. The setting of the wiper assembly 200 is intended to clean the lens viewing window 40 and the supplementary light viewing window 40 through the swinging wiper 230. The wiper assembly 200 includes a second housing 210 as the bearing base, a driving assembly 220 and a wiper 230 disposed on the first housing 110. The second housing 210 is disposed below the first housing 110 for carrying the first housing 110. And in order to improve the relative position stability between the second housing 210 and the first housing 110, at least the outer contour of the front end portion of the first housing 110 is set to be circular. An arc-shaped groove adapted to the front end portion of the first housing 110 is provided on the top surface of the second housing 210, such that the front end portion of the first housing 110 is received within the arc-shaped groove. At this time, the deviation of the first housing 110 and the second housing 210 in the horizontal direction parallel to the front end face can be avoided. At this time, the first housing 110 and the second housing 210 can be connected and fixed by means such as bolt connection or snap connection 213 as in the following embodiments. After the first housing 110 and the second housing 210 are relatively fixed, the front end faces of the first housing 110 and the second housing 210 are substantially flush. In the wiper assembly 200, the driving assembly 220 is disposed within the second housing 210, such that the rotating shaft 240 of the driving assembly 220 passes through the front end face of the second housing 210 and is parallel to the optical axis of the lens assembly 30 in the camera 100, that is, perpendicular to the front end face of the first housing 110. The wiper 230 of the wiper assembly 200 is disposed on the front side of the front end face of the second housing 210, and one end of the wiper 230 is connected to the rotating shaft 240 to swing under the drive of the driving assembly 220, and at the same time, the swinging path of the wiper 230 passes through the front end face of the first housing 110, such that the wiper 230 fits against the lens viewing window 40 and the supplementary light viewing window 40 during the swinging process. With such a setting, when the lens viewing window 40 and the supplementary light viewing window 40 are contaminated with dust and other debris, the wiper 230 can scrape off the debris.
[0199] In the wiper assembly 200 of the camera system 1000, since the rotating shaft 240 of the driving assembly 220 passes outwards from inside the second housing 210, if the sealing performance between the rotating shaft 240 and the second housing 210 is poor, it is easy for foreign objects from the outside to enter the second housing 210. When the camera system 1000 is applied to an underwater environment, under the action of water pressure, water and foreign objects in the water are more likely to enter the second housing 210.
[0200] In this embodiment, a first sealing sleeve 320 is provided in the wiper assembly 200. The first sealing sleeve 320 includes a connected first sealing section 321 and a second sealing section 322, and the outer diameter of the first sealing section 321 increases from outside to inside. Correspondingly, a through hole 2111 penetrating into the second housing 210 is formed in the front end face of the second housing 210. The through hole 2111 includes a second limiting hole 2111b and a third limiting hole 2111a that are connected in sequence from outside to inside. Among them, the second limiting hole 2111b is a flared hole with a gradually increasing aperture from outside to inside, so that the first sealing sleeve 320 is inserted into the through hole 2111 from inside the second housing 210, and then the first sealing pressing plate 340 is fixed to the inner wall of the second housing 210 to press 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 first sealing sleeve 320 is made of an elastic material such as silica gel or rubber, so that when the first sealing sleeve 320 abuts against the hole wall of the through hole 2111, it undergoes elastic deformation to closely adhere to the hole wall of the through hole 2111. In addition, the first sealing sleeve 320 and the rotating shaft 240 are in an interference fit so that the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240, and is clamped between the rotating shaft 240 and the hole wall of the through hole 2111 and is compressed, so that the first sealing sleeve 320 completely seals the gap between the rotating shaft 240 and the hole wall of the through hole 2111, preventing foreign objects from entering the second housing 210 from the through hole 2111. Further, since the outer diameter of the first sealing section 321 increases from outside to inside and the second limiting hole 2111b is in a flared hole structure and squeezes the outer wall of the first sealing section 321, the first seal is deformed inwards by the squeezing force from outside to inside of the hole wall of the second limiting hole 2111b, thereby pre-clamping the rotating shaft 240, ensuring that the inner wall of the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240 and playing a good sealing role. When the camera 100 is applied to an underwater environment, the first sealing section 321 is deformed towards the inside of the second housing 210 under the action of the water pressure from outside to inside and closely adheres to the rotating shaft 240, improving the sealing performance and effectively blocking foreign objects from entering the second housing 210.
[0201] Further, a first crimping rib 324 protrudes from the outer side wall 1332 of the second sealing section 322. The first crimping rib 324 is arranged to surround the circumference of the second sealing section 322. When the first sealing sleeve 320 is inserted into the through hole 2111, the first crimping rib 324 is pressed against and fits with the hole wall of the third limiting hole 2111a. With such an arrangement, the local outer diameter of the second sealing section 322 is increased by the first crimping rib 324, so that the second sealing section 322 can fully block between the third limiting hole 2111a and the rotating shaft 240, increasing the compression amount of the second sealing section 322, improving the sealing performance, and preventing the entire outer diameter of the second sealing section 322 from increasing, which may cause difficulty in inserting the first sealing sleeve 320 into the through hole 2111. Among them, at least two first crimping ribs 324 can be provided, and at least two first crimping ribs 324 are arranged in sequence along the axial direction of the rotating shaft 240, so as to play a role in multi-stage sealing and improve the sealing performance.
[0202] Referring Figures 15 to 17 , the present application also proposes a camera system 1000, and the camera system 1000 includes:
[0203] A camera 100, which includes a first housing 110 and a window 40 provided at the front end of the first housing 110;
[0204] A wiper assembly 200, which includes a second housing 210, a rotating shaft 240, and a wiper 230. The top end of the second housing 210 supports the first housing 110. The axis of the rotating shaft 240 is parallel to the optical axis of the camera 100. Under the action of a driving force, the rotating shaft 240 drives the wiper 230 to swing along the window 40;
[0205] Among them, the wiper assembly 200 further includes:
[0206] A through hole 2111 penetrating the second housing 2, and the through hole 2111 includes a second limiting hole 2111b and a third limiting hole 2111a along the axial direction. The radial radius of the second limiting hole 2111b increases along the axial direction, and the radial radius of the third limiting hole 2111a remains unchanged along the axial direction;
[0207] A first sealing sleeve 320, which includes a first limiting section 3322 with a flared shape and a second limiting section 3322 with a first crimping rib 324 on the outer side wall 1332 along the axial direction;
[0208] A sealing bracket 310 with a closed cavity;
[0209] Two second sealing sleeves 330, which are arranged at both ends of the sealing bracket 310 along the axial direction;
[0210] When the camera system 1000 is disposed in water, the wiper assembly 200 is configured such that the rotating shaft 240 sequentially passes through two second seal sleeves 330, a seal bracket 310, and a first seal sleeve 320 and is fastened to the wiper 230. The through hole 2111 accommodates the first seal sleeve 320 such that the inner circumference of the through hole 2111 and the outer circumference of the first seal sleeve 320 form a first seal area and a second seal area. The first seal area is formed by the radial abutment of the second limiting hole 2111b and the first seal section 321, and the second seal area is formed by the radial abutment of the third limiting hole 2111a and the second seal section 322. The seal bracket 310 is relatively fastened to the second housing 210, so that substances in water are blocked outside the second housing 210 by the first seal area, the second seal area, the seal bracket 310, and the two second seal sleeves 330.
[0211] The camera system 1000 proposed in this embodiment mainly includes a camera 100 and a wiper assembly 200. The camera 100, as the main functional component for image acquisition, includes a first housing 110 as the bearing base, a fill light 90 and a lens assembly 30 disposed within the first housing 110. It is defined that the camera 100 has a front-back direction, and the front end of the camera 100 is oriented towards the position to be observed. A viewing window 40 is provided on the front end face of the first housing 110, which can be only the lens viewing window 40, and in some embodiments, the fill light viewing window 40 and the lens viewing window 40 can also be provided simultaneously. The fill light 90 within the first housing 110 is oriented towards the fill light viewing window 40, and the lens assembly 30 is oriented towards the lens viewing window 40, so that the lens assembly 30 can collect image information of the position to be observed through the lens viewing window 40, and the light emitted by the fill light 90 can be emitted forward through the fill light viewing window 40, improving the brightness of the position to be observed and making the image collected by the lens assembly 30 clearer. The setting of the wiper assembly 200 is intended to clean the lens viewing window 40 and the fill light viewing window 40 through the swinging wiper 230. The wiper assembly 200 includes a second housing 210 as the bearing base, a driving assembly 220 and a wiper 230 disposed on the first housing 110. The second housing 210 is disposed below the first housing 110 for carrying the first housing 110. In order to improve the relative position stability between the second housing 210 and the first housing 110, at least the outer contour of the front end portion of the first housing 110 is set to be circular, and an arc-shaped groove adapted to the front end portion of the first housing 110 is provided on the top surface of the second housing 210, so that the front end portion of the first housing 110 is received within the arc-shaped groove. At this time, the deviation of the first housing 110 and the second housing 210 in the horizontal direction parallel to the front end face can be avoided. At this time, the first housing 110 and the second housing 210 can be connected and fixed by means such as bolt connection or snap connection 213 as in the following embodiments. After the first housing 110 and the second housing 210 are relatively fixed, the front end faces of the first housing 110 and the second housing 210 are substantially flush. In the wiper assembly 200, the driving assembly 220 is disposed within the second housing 210, so that the rotating shaft 240 of the driving assembly 220 passes through the front end face of the second housing 210 and is parallel to the optical axis of the lens assembly 30 in the camera 100, that is, perpendicular to the front end face of the first housing 110. The wiper 230 of the wiper assembly 200 is disposed on the front side of the front end face of the second housing 210, and one end of the wiper 230 is connected to the rotating shaft 240 to swing under the drive of the driving assembly 220, and at the same time, the swinging path of the wiper 230 passes through the front end face of the first housing 110, so that the wiper 230 fits on the lens viewing window 40 and the fill light viewing window 40 during the swinging process. With such a setting, when the lens viewing window 40 and the fill light viewing window 40 are contaminated with dust and other debris, the wiper 230 can scrape off the debris.
[0212] In the wiper assembly 200 of the camera system 1000, since the rotating shaft 240 of the drive assembly 220 passes outwards from within the second housing 210, if the sealing performance between the rotating shaft 240 and the second housing 210 is poor, it is easy for foreign objects from the outside to enter the second housing 210. When the camera system 1000 is applied to an underwater environment, under the action of water pressure, water and foreign objects in the water are more likely to enter the second housing 210.
[0213] In this embodiment, a sealing assembly 300 formed by combining a first sealing sleeve 320, a sealing bracket 310, and a second sealing sleeve 330 is provided in the wiper assembly 200. Among them, the sealing bracket 310 is a cylindrical structure with an open end, and the cross-sectional shape of the sealing bracket 310 can be polygonal, circular, or other regular or irregular shapes, which is not limited herein; the sealing bracket 310 is fixed on a part of the inner wall of the second housing 210 where a through hole 2111 is provided, so that the inner wall of the second housing 210 where the through hole 2111 is provided seals the opening of the sealing bracket 310 to form a sealed space inside the sealing bracket 310. At the same time, an installation hole 311 for passing through the rotating shaft 240 is provided on the bottom wall 1331 of the cylinder of the sealing bracket 310 opposite to the inner wall of the second housing 210, so that the first sealing sleeve 320 is inserted into the through hole 2111, and the first sealing sleeve 320 includes a connected first sealing section 321 and a second sealing section 322. The outer diameter of the first sealing section 321 increases from outside to inside. The through hole 2111 includes a second limiting hole 2111b and a third limiting hole 2111a that are sequentially connected from outside to inside. Among them, the second limiting hole 2111b is a flared hole with a gradually increasing aperture from outside to inside, so that the first sealing sleeve 320 is inserted into the through hole 2111 from the inside of the second housing 210, and then the first sealing pressing plate 340 is fixed on the inner wall of the second housing 210 to press 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 first sealing sleeve 320 is made of an elastic material such as silica gel or rubber, so that when the first sealing sleeve 320 abuts against the hole wall of the through hole 2111, it undergoes elastic deformation to closely adhere to the hole wall of the through hole 2111; in addition, the first sealing sleeve 320 and the rotating shaft 240 are in an interference fit so that the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240, and is clamped between the rotating shaft 240 and the hole wall of the through hole 2111 and is compressed so that the first sealing sleeve 320 completely seals the gap between the rotating shaft 240 and the hole wall of the through hole 2111, preventing foreign objects from entering the second housing 210 from the through hole 2111; further, since the outer diameter of the first sealing section 321 increases from outside to inside, the second limiting hole 2111b has a flared hole structure and presses the outer wall of the first sealing section 321, so that the first seal is deformed inward by the squeezing force of the hole wall of the second limiting hole 2111b from outside to inside to pre-clamp the rotating shaft 240, ensuring that the inner wall of the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240 and playing a good sealing role. When the camera 100 is applied to an underwater environment, the first sealing section 321 is deformed further into the second housing 210 under the action of the water pressure from outside to inside and closely adheres to the rotating shaft 240, improving the sealing performance and effectively isolating foreign objects from entering the second housing 210.
[0214] In addition, at least two second sealing sleeves 330 are sequentially arranged along the axial direction of the rotating shaft 240 in the mounting hole 311. When each second sealing sleeve 330 is clamped between the hole wall of the mounting hole 311 and the rotating shaft 240, the second sealing sleeve 330 undergoes compressive deformation, so that the second sealing sleeve 330 closely adheres to the hole wall of the mounting hole 311 and the outer surface of the rotating shaft 240, effectively blocking the gap between the hole wall of the mounting hole 311 and the rotating shaft 240, playing a good sealing role and avoiding damaging the sealing performance of the sealed space. With such an arrangement, the rotating shaft 240 sequentially passes through the first sealing sleeve 320, the sealing bracket, and at least two second sealing sleeves 330, so as to form multiple-stage seals in sequence from the inside to the outside along the axial direction of the rotating shaft 240 in the second housing 210, effectively improving the sealing performance at the position of the rotating shaft 240 and preventing foreign objects from entering the second housing 210 along the rotating shaft 240.
[0215] Referring to Figures 14 to 16 , the present application further provides a camera system 1000, and the camera system 1000 includes:
[0216] A camera 100, the camera 100 includes a viewing window 40;
[0217] A wiper assembly 200 for supporting the camera 100, the wiper assembly 200 includes a second housing 210 with a through hole 2111, a rotating shaft 240 passing through the through hole 2111, and a wiper 230. The rotating shaft 240 drives the wiper 230 to swing and adhere to the viewing window 40. The through hole 2111 includes a first limiting hole 2111c, a second limiting hole 2111b, and a third limiting hole 2111a. The radial radius of the second limiting hole 2111b gradually increases along the axial inward direction, the radial radius of the first limiting hole 2111c remains unchanged and the radial radius of the first limiting hole 2111c also remains unchanged and is smaller than the radial radius of the third limiting hole 2111a;
[0218] The wiper assembly 200 further includes a first sealing sleeve 320, a shaft sleeve 380, and a compression screw 250;
[0219] The first sealing sleeve 320 is defined as: the first sealing sleeve 320 includes a first sealing section 321 and a second sealing section 322. The outer peripheral surface shape of the first sealing section 321 is adapted to the second limiting hole 2111b, and the outer peripheral surface of the second sealing section 322 has a first crimping rib 324; the inner surface of the first sealing sleeve 320 includes two truncated cones that are sequentially penetrated along the axial inward direction, and the radial radius of any truncated cone is smaller than the radial radius of the rotating shaft 240;
[0220] The compression screw 250 is sleeved on the rotating shaft 240 and is located at one end of the wiper 230 facing away from the second housing 210 to compress the wiper 230;
[0221] The wiper assembly 200 is configured such that: along the inward direction of the axis of the rotating shaft 240, the first limiting hole 2111c houses the bushing 380, the second limiting hole 2111b houses the first sealing section 321, and the third limiting hole 2111a houses the second sealing section 322, so that the inner circumference of the through hole 2111 is successively abutted by the outer circumference of the bushing 380 against the first limiting hole 2111c, the first sealing section 321 against the second limiting hole 2111b, and the second sealing section 322 against the third limiting hole 2111a, thereby sealing and plugging the through hole 2111. At the same time, the rotating shaft 240 is successively subjected to the pressing forces of the inner walls of the bushing 380, the first sealing section 321, and the second sealing section 322, so that the axis of the rotating shaft 240 does not deviate during rotation.
[0222] The camera system 1000 proposed in this embodiment mainly includes a camera 100 and a wiper assembly 200. The camera 100, as the main functional component for image acquisition, includes a first housing 110 as the bearing base and a fill light 90 and a lens assembly 30 disposed within the first housing 110. It is defined that the camera 100 has a front-back direction, and the front end of the camera 100 is arranged towards the position to be observed. A window 40 is provided on the front end face of the first housing 110. It can be only the lens window 40, and in some embodiments, the fill light window 40 and the lens window 40 can also be provided simultaneously, so that the fill light 90 within the first housing 110 is arranged towards the fill light window 40, and the lens assembly 30 is arranged towards the lens window 40. Thus, 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, improving the brightness of the position to be observed and making the image collected by the lens assembly 30 clearer.The wiper assembly 200 is arranged to clean the lens window 40 and the fill light window 40 by the swinging wiper 230. The wiper assembly 200 includes a second housing 210 as a bearing base, a driving assembly 220 and a wiper 230 arranged on the first housing 110. The second housing 210 is arranged below the first housing 110 for bearing the first housing 110. In order to improve the relative position stability between the second housing 210 and the first housing 110, at least the outer contour of the front end portion in the first housing 110 is set to be circular, and an arc-shaped groove adapted to the front end portion of the first housing 110 is arranged on the top surface of the second housing 210, so that the front end portion of the first housing 110 is accommodated in the arc-shaped groove. At this time, the deviation of the first housing 110 and the second housing 210 in the horizontal direction parallel to the front end surface can be avoided. At this time, the first housing 110 and the second housing 210 can be connected and fixed by means such as bolt connection or snap connection 213 as in the following embodiments. After the first housing 110 and the second housing 210 are relatively fixed, the front end surface of the first housing 110 and the front end surface of the second housing 210 are arranged to be substantially flush. In the wiper assembly 200, the driving assembly 220 is arranged in the second housing 210, so that the rotating shaft 240 of the driving assembly 220 passes through the front end surface of the second housing 210 and is parallel to the optical axis of the lens assembly 30 in the camera 100, that is, perpendicular to the front end surface of the first housing 110. The wiper 230 of the wiper assembly 200 is arranged on the front side of the front end surface of the second housing 210, and one end of the wiper 230 is connected to the rotating shaft 240, and a pressing screw 250 is sleeved on the end of the rotating shaft 240 away from the second housing 210, so that the wiper 230 is pressed and locked on the rotating shaft 240 by the pressing screw 250 to swing under the drive of the driving assembly 220, and at the same time, the swinging path of the wiper 230 passes through the front end surface of the first housing 110, so that the wiper 230 fits on 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 sundries, the wiper 230 can scrape off the sundries.
[0223] In the wiper assembly 200 of the camera system 1000, since the rotating shaft 240 of the driving assembly 220 passes outwards from the second housing 210, if the sealing performance between the rotating shaft 240 and the second housing 210 is poor, it is easy to cause foreign objects from the outside to enter the second housing 210. When the camera system 1000 is applied to an underwater environment, under the action of water pressure, water and foreign objects in the water are more likely to enter the second housing 210.
[0224] In this embodiment, a sealing assembly 300 formed by combining a first sealing sleeve 320, a sealing bracket 310, and a second sealing sleeve 330 is provided in the wiper assembly 200. Among them, the sealing bracket 310 is a cylindrical structure with an open end. The cross-sectional shape of the sealing bracket 310 can be polygonal, circular, or other regular or irregular shapes, which is not limited herein; the sealing bracket 310 is fixed on a part of the inner wall of the second housing 210 where a through hole 2111 is provided, so that the inner wall of the second housing 210 where the through hole 2111 is provided seals the opening of the sealing bracket 310 to form a sealed space inside the sealing bracket 310. At the same time, an installation hole 311 for passing through the rotating shaft 240 is provided on the bottom wall 1331 of the cylinder of the sealing bracket 310 opposite to the inner wall of the second housing 210. The first sealing sleeve 320 is inserted into the through hole 2111, and the first sealing sleeve 320 includes a connected first sealing section 321 and a second sealing section 322. The outer diameter of the first sealing section 321 increases from outside to inside. The through hole 2111 includes a second limiting hole 2111b and a third limiting hole 2111a that are connected in sequence from outside to inside. Among them, the second limiting hole 2111b is a flared hole with a gradually increasing aperture from outside to inside, so that the first sealing sleeve 320 is inserted into the through hole 2111 from the inside of the second housing 210, and then the first sealing pressing plate 340 is fixed to the inner wall of the second housing 210 to press 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 first sealing sleeve 320 is made of an elastic material such as silica gel or rubber, so that when the first sealing sleeve 320 abuts against the hole wall of the through hole 2111, it undergoes elastic deformation to closely adhere to the hole wall of the through hole 2111; in addition, the first sealing sleeve 320 and the rotating shaft 240 are in an interference fit so that the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240, and is clamped between the rotating shaft 240 and the hole wall of the through hole 2111 and is compressed so that the first sealing sleeve 320 completely seals the gap between the rotating shaft 240 and the hole wall of the through hole 2111, preventing foreign objects from entering the second housing 210 from the through hole 2111; further, since the outer diameter of the first sealing section 321 increases from outside to inside and the second limiting hole 2111b is in a flared hole structure and squeezes the outer wall of the first sealing section 321, the first seal is deformed inward by the squeezing force from outside to inside of the hole wall of the second limiting hole 2111b to pre-clamp the rotating shaft 240, ensuring that the inner wall of the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240 and playing a good sealing role. When the camera 100 is applied to an underwater environment, the first sealing section 321 is deformed further into the second housing 210 under the action of the water pressure from outside to inside and closely adheres to the rotating shaft 240, improving the sealing performance and effectively isolating foreign objects from entering the second housing 210.Furthermore, the inner surface of the first sealing sleeve 320 includes two cones that pass through one another in the axial inward direction, and the radial radius of any cone is smaller than the radial radius of the rotating shaft 240; wherein, the inclined side wall 1332 of each cone gradually approaches the rotating shaft 240 from the inside to the outside to form a sealing lip 326. With such an arrangement, when the cone is subjected to water pressure from the outside to the inside, it further deforms into the second shell 210 and fits tightly against the rotating shaft 240, thereby further improving the sealing performance and effectively isolating external foreign matter from entering the second shell 210.
[0225] 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.
[0226] Reference Figure 14 The present application further proposes a camera system 1000, which includes:
[0227] The housing assembly is provided with a viewing window 40 and a shaft hole, and the inner wall of the housing assembly is provided with a shaft hole and a communicating sealing hole;
[0228] The lens assembly 30 is disposed in the housing assembly and faces the viewing window 40;
[0229] The wiper mechanism includes a wiper 230, a rotating shaft 240, and a drive assembly 220. The rotating shaft 240 is disposed in the rotating shaft hole. The wiper 230 is disposed outside the housing assembly and connected to the rotating shaft 240. The drive assembly 220 is disposed inside the housing assembly and is in driving connection with the rotating shaft 240 to drive the wiper 230 to swing in the area of the window 40.
[0230] The sealing assembly 300 is disposed within the housing assembly and includes a sealing bracket 310, a first sealing sleeve 320, and a second sealing sleeve 330. The sealing bracket 310 and the inner wall of the housing assembly enclose a sealed space. The sealing bracket 310 has a mounting hole 311 that communicates with the sealing hole, and the rotating shaft 240 is disposed through the mounting hole 311.
[0231] The first sealing sleeve 320 is sleeved on the rotating shaft 240 and inserted into the sealing hole to be sandwiched between the rotating shaft 240 and the hole wall of the sealing hole;
[0232] The second sealing sleeve 330 is sleeved on the rotating shaft 240 and inserted into the mounting hole 311 so as to be sandwiched between the rotating shaft 240 and the wall of the mounting hole 311 .
[0233] The camera system 1000 proposed in this embodiment mainly includes a housing assembly, a lens assembly 30, a wiper mechanism, and a sealing assembly 300. The housing assembly can be an integral structure or a split structure. When the housing 110 is an integral structure, the lens assembly 30, the sealing assembly 300, and at least part of the wiper mechanism are all arranged in the same cavity of the housing assembly. Of course, the housing assembly can be a split structure, including a first housing 110 and a second housing 210. The lens assembly 30 is installed in the first housing 110 to form a camera 100 as the main functional component for image acquisition, and the wiper mechanism and the sealing assembly 300 are installed in the second housing 210 to form a wiper assembly 200, so that different functional components have independent accommodation cavities to reduce interference; the specific implementation of the housing assembly is not limited here. Taking the housing assembly as a split structure as an example, at this time the camera system 1000 includes a split camera 100 and a wiper assembly 200, and the two are electrically connected through a cable assembly 80. Among them, the camera 100 includes a first housing 110 as a bearing base and a supplementary light 90 and a lens assembly 30 arranged in the first housing 110. It is defined that the camera 100 has a front-back direction, and the front end of the camera 100 is arranged towards the position to be observed. A viewing window 40 is arranged on the front end face of the first housing 110. It can be only the lens viewing window 40 arranged, and in some embodiments, the supplementary light viewing window 40 and the lens viewing window 40 can also be arranged at the same time, so that the supplementary light 90 in the first housing 110 is arranged towards the supplementary light viewing window 40, and the lens assembly 30 is arranged towards the lens viewing window 40, so that the lens assembly 30 can collect image information of the position to be observed through the lens viewing window 40, and the light emitted by the supplementary light 90 can be emitted forward through the supplementary light viewing window 40 to increase the brightness of the position to be observed, making the image collected by the lens assembly 30 clearer.The wiper assembly 200 is arranged to clean the lens window 40 and the fill light window 40 by the swinging wiper 230. The wiper assembly 200 includes a second housing 210 as a bearing base, a drive assembly 220 and a wiper 230 arranged on the first housing 110. The second housing 210 is arranged below the first housing 110 for bearing the first housing 110. In order to improve the relative position stability between the second housing 210 and the first housing 110, at least the outer contour of the front end portion in the first housing 110 is set to be circular, and an arc-shaped groove adapted to the front end portion of the first housing 110 is arranged on the top surface of the second housing 210, so that the front end portion of the first housing 110 is accommodated in the arc-shaped groove. At this time, the deviation of the first housing 110 and the second housing 210 in the horizontal direction parallel to the front end face can be avoided. At this time, the first housing 110 and the second housing 210 can be connected and fixed by means such as bolt connection or snap connection 213 as in the following embodiments. After the first housing 110 and the second housing 210 are relatively fixed, the front end faces of the first housing 110 and the second housing 210 are arranged to be substantially flush. In the wiper assembly 200, the drive assembly 220 is arranged in the second housing 210, so that the rotating shaft 240 of the drive assembly 220 passes out from the front end face of the second housing 210 and is parallel to the optical axis of the lens assembly 30 in the camera 100, that is, perpendicular to the front end face of the first housing 110. The wiper 230 of the wiper assembly 200 is arranged on the front side of the front end face of the second housing 210, and one end of the wiper 230 is connected to the rotating shaft 240 to swing under the drive of the drive assembly 220, and at the same time, the swinging path of the wiper 230 passes through the front end face of the first housing 110, so that the wiper 230 fits on 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 sundries, the wiper 230 can scrape off the sundries.
[0234] In the wiper assembly 200 of the camera system 1000, since the rotating shaft 240 of the drive assembly 220 passes out from the second housing 210 to the outside, if the sealing performance between the rotating shaft 240 and the second housing 210 is poor, it is easy to cause foreign objects from the outside to enter the second housing 210. When the camera system 1000 is applied to an underwater environment, under the action of water pressure, water and foreign objects in the water are more likely to enter the second housing 210.
[0235] In this embodiment, a sealing assembly 300 formed by combining a first sealing sleeve 320, a sealing bracket 310, and a second sealing sleeve 330 is provided in the wiper assembly 200. Among them, the sealing bracket 310 is a cylindrical structure with an open end. The cross-sectional shape of the sealing bracket 310 can be polygonal, circular, or other regular or irregular shapes, which is not limited herein. The sealing bracket 310 is fixed to a part of the inner wall of the second housing 210 where a sealing hole is provided, so that the inner wall of the second housing 210 where the sealing hole is provided seals the opening of the sealing bracket 310 to form a sealed space inside the sealing bracket 310. At the same time, an installation hole 311 for passing through the rotating shaft 240 is provided on the bottom wall 1331 of the cylinder of the sealing bracket 310 opposite to the inner wall of the second housing 210. The first sealing sleeve 320 is inserted into the sealing hole and sleeved on the rotating shaft 240, so that the first sealing sleeve 320 is clamped between the rotating shaft 240 and the hole wall of the sealing hole. The first sealing sleeve 320 is made of materials such as silica gel or rubber and can be squeezed and deformed, so that the first sealing sleeve 320 can closely adhere to the hole wall of the sealing hole and the outer surface of the rotating shaft 240 to completely seal the gap between the sealing hole and the rotating shaft 240, playing a good sealing role. When the second sealing sleeve 330 is clamped between the hole wall of the installation hole 311 and the rotating shaft 240, the second sealing sleeve 330 undergoes compressive deformation, so that the second sealing sleeve 330 closely adheres to the hole wall of the installation hole 311 and the outer surface of the rotating shaft 240, effectively sealing the gap between the hole wall of the installation hole 311 and the rotating shaft 240, playing a good sealing role and avoiding damaging the sealing performance of the sealed space. With such a setting, the rotating shaft 240 sequentially passes through the first sealing sleeve 320, the sealing bracket, and the second sealing sleeve 330 to form multiple levels of sealing in sequence along the axial direction of the rotating shaft 240 from the inside to the outside in the second housing 210, effectively improving the sealing performance of the position of the rotating shaft 240 and preventing foreign objects from entering the second housing 210 along the rotating shaft 240.
[0236] In some embodiments, the sealing hole includes a second limiting hole 2111b and a third limiting hole 2111a that are sequentially communicated from outside to inside. The first sealing sleeve 320 includes a connected first sealing section 321 and a second sealing section 322. The outer diameter of the first sealing section 321 increases from outside to inside. 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. 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 first sealing sleeve 320 is made of an elastic material such as silica gel or rubber, so that when the first sealing sleeve 320 abuts against the hole wall of the sealing hole, elastic deformation occurs to closely adhere to the hole wall of the sealing hole. Additionally, the first sealing sleeve 320 and the rotating shaft 240 are in an interference fit, so that the first sealing sleeve 320 closely adheres to the surface of the rotating shaft 240 and is clamped between the rotating shaft 240 and the hole wall of the sealing hole to be compressed, so that the first sealing sleeve 320 completely blocks the gap between the rotating shaft 240 and the hole wall of the sealing hole, preventing foreign objects from entering the second housing 210 from the rotating shaft hole and the sealing hole.
[0237] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields, is included in the patent protection scope of the present invention.
