Description

Technical Field

[0001] This application belongs to the technical field of camera design, and particularly relates to a camera. Background Art

[0002] As one of the imaging devices, cameras have now been widely used in various industries. At the same time, cameras can also be used in many aspects of people's work, life, and entertainment, such as using cameras for security monitoring, etc.

[0003] According to the installation environment of the camera, it can be divided into indoor cameras and outdoor cameras. Among them, outdoor cameras are usually equipped with a wiper assembly for removing water stains on the shooting window of the camera to improve the clarity of the camera's shooting picture. Usually, the rotating shaft of the wiper assembly is arranged on the outer shell of the camera. At this time, the distance between the rotating shaft and the central area of the shooting window is relatively far, resulting in a relatively long wiper length of the wiper assembly, thus affecting the wiping performance of the wiper assembly. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a camera that can solve the problem that the distance between the rotating shaft of the wiper assembly of the current camera and the central area of the shooting window is relatively long, resulting in poor wiping performance of the wiper assembly.

[0005] To solve the above technical problems, this application is implemented as follows:

[0006] In a first aspect, the embodiments of this application provide a camera, including a housing, a wiper assembly, and a driving member.

[0007] The housing has a receiving cavity. The housing includes a connected housing body and a shooting window, and through holes are provided at the edge of the shooting window.

[0008] The wiper assembly includes a connected rotating shaft and a wiper. The wiper is movably arranged on the outer surface of the shooting window. One end of the rotating shaft extends through the through hole into the receiving cavity, and the rotating shaft is rotatably and sealingly fitted with the shooting window.

[0009] The driving member is arranged in the receiving cavity. The output shaft of the driving member is connected to the rotating shaft. The driving member can drive the wiper to rotate along the outer surface of the shooting window through the rotating shaft, and the wiper is adaptively pressed against the shooting window.

[0010] In a second aspect, the embodiments of this application also provide another camera, including a shooting window and a wiper assembly. Through holes are provided at the edge of the shooting window, and the through holes penetrate the shooting window.

[0011] The wiper assembly includes a rotating shaft. One end of the rotating shaft passes through the through hole, and the rotating shaft is sealingly fitted with the shooting window.

[0012] The structure for the sealing fit includes a sealing assembly, and the sealing assembly includes a sealing ring, a sealing pressing ring and a sealing shaft sleeve;

[0013] Wherein, the sealing ring includes a first annular portion, a sleeve structure and a second annular portion connected in sequence, and the first annular portion is opposite to the second annular portion;

[0014] Wherein, the sealing pressing ring includes an annular pressing plate and a connecting sleeve connected thereto, and the inner wall of the connecting sleeve has internal threads;

[0015] Wherein, the sealing shaft sleeve includes external threads, a sealing end face and a limiting end face, and both the sealing end face and the limiting end face form stepped surfaces;

[0016] The camera is configured as:

[0017] The inner wall of the through hole receives the sealing ring, the sealing shaft sleeve is arranged from the inside to the outside along the thickness direction of the shooting window, and the sealing pressing ring is arranged from the outside to the inside along the thickness direction of the shooting window, so that the external threads of the sealing shaft sleeve are locked with the internal threads of the sealing pressing ring, the connecting sleeve abuts against the limiting end face, the annular pressing plate abuts against the second annular portion, and the sealing end face abuts against the first annular portion, thereby forming the sealing fit.

[0018] In the embodiment of the present application, a through hole is provided at the edge of the shooting window. One end of the rotating shaft of the wiper assembly passes through the through hole and extends into the accommodation cavity and is connected to the output shaft of the driving member. The rotating shaft is rotatably and sealingly fitted with the shooting window to prevent water stains from entering the inside of the camera. The driving member can drive the wiper to rotate along the outer surface of the shooting window through the rotating shaft, so as to scrape off the water stains on the outer surface of the shooting window to ensure the clarity of the shooting picture of the camera. This solution shortens the distance between the rotating shaft and the central area of the shooting window by providing a through hole at the edge of the shooting window, thereby moving the rotating shaft of the wiper assembly from the housing of the camera to the shooting window, and at this time, the length of the wiper can be reduced, so as to improve the scraping performance of the wiper; and, during the process that the driving member drives the wiper to rotate relative to the shooting window through the rotating shaft, the wiper can be adaptively pressed against the shooting window, so that the wiper is always in full contact with the shooting window, thereby further improving the scraping performance of the wiper.

[0056] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0057] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally represents an "or" relationship between the associated objects before and after.

[0058] Next, the camera provided in the embodiments of the present application will be described in detail in conjunction with the accompanying drawings through specific embodiments and their application scenarios.

[0059] As Figures 1 to 32 shown, an embodiment of the present application discloses a camera, which includes a housing 100, a wiper assembly 200 and a driving member 300. Optionally, the camera can be an outdoor camera. Optionally, the driving member 300 can be a driving device such as a motor, and the embodiments of the present application do not make specific limitations thereto.

[0060] The housing 100 has a receiving cavity. The housing 100 includes a connected housing body 110 and a shooting window 120. Optionally, the housing body 110 and the shooting window 120 can be hermetically connected through a sealing member to prevent impurities such as water stains and dust in the external environment from entering the receiving cavity, thereby protecting the structures arranged in the receiving cavity, such as lenses, speakers, etc. Optionally, the shooting window 120 can be a light-transmitting structure, specifically, it can be glass, etc., and no specific limitation is made here. Through holes 121 are provided at the edge of the shooting window 120.

[0061] The wiper assembly 200 includes a connected rotating shaft 210 and a wiper 220. The wiper 220 is movably arranged on the outer surface of the shooting window 120, that is, the wiper 220 can move relative to the outer surface of the shooting window 120 to scrape off impurities such as water stains and dust on the shooting window 120, thereby improving the clarity of the picture captured by the lens. One end of the rotating shaft 210 passes through the through hole 121 and extends into the receiving cavity of the housing 100. The rotating shaft 210 is rotatably and hermetically fitted with the shooting window 120 to prevent impurities such as water stains and dust from entering the interior of the camera.

[0062] The driving member 300 is arranged in the receiving cavity of the housing 100. The output shaft of the driving member 300 is connected to the rotating shaft 210. The driving member 300 can drive the wiper 220 to rotate along the outer surface of the shooting window 120 through the rotating shaft 210, thereby scraping off impurities such as water stains and dust on the outer surface of the shooting window 120 to ensure the clarity of the picture captured by the camera, and the wiper 220 is adaptively pressed against the shooting window 120, that is, during the process that the driving member 300 drives the wiper 220 to rotate along the outer surface of the shooting window 120, the wiper 220 can be adjusted according to the curvature change of the outer surface of the shooting window 120 so that the wiper 220 is always in full contact with the shooting window 120.

[0063] In the embodiment of the present application, by opening the through hole 121 at the edge of the shooting window 120, the rotating shaft 210 of the wiper assembly 200 is moved from the housing body 110 of the camera to the shooting window 120, so as to shorten the distance between the rotating shaft 210 and the central area of the shooting window 120. At this time, the length of the wiper 220 can be reduced, thereby improving the scraping performance of the wiper 220; and, during the process that the driving member 300 drives the wiper 220 to rotate relative to the shooting window 120 through the rotating shaft 210, the wiper 220 is adaptively pressed against the shooting window 120 so that the wiper 220 is always in full contact with the shooting window 120, thereby further improving the scraping performance of the wiper 220. Therefore, the embodiment of the present application can solve the problem that the distance between the rotating shaft 210 of the wiper assembly 200 of the current camera and the central area of the shooting window 120 is relatively long, resulting in poor scraping performance of the wiper assembly 200.

[0064] Optionally, the camera further includes a circuit board 800 disposed in the receiving cavity of the housing 100, and the circuit board 800 is electrically connected to the driving member 300.

[0065] Optionally, an annular groove may be provided on one of the outer surface of the rotating shaft 210 and the inner surface of the through hole 121, and an annular protrusion may be provided on the other. At this time, the annular protrusion cooperates with the annular groove to enable the rotating shaft 210 to be sealingly fitted with the inner wall of the through hole 121, thereby preventing impurities such as water stains and dust in the external environment from entering the receiving cavity of the housing 100; or, in an alternative embodiment, the camera further includes a sealing assembly 400 sleeved on the rotating shaft 210. The sealing assembly 400 is disposed on the shooting window 120. The rotating shaft 210 can rotate relative to the sealing assembly 400. The rotating shaft 210 is sealingly fitted with the shooting window 120 through the sealing assembly 400. The sealing assembly 400 includes a sealing shaft sleeve 410 and a sealing ring 420. At least part of the sealing ring 420 and at least part of the sealing shaft sleeve 410 are both disposed in the through hole 121 of the shooting window 120. The sealing shaft sleeve 410 is rotatably sleeved on the rotating shaft 210, that is, the rotating shaft 210 is in direct contact with the sealing shaft sleeve 410. Optionally, the sealing shaft sleeve 410 can be a rigid structure with good wear resistance. The sealing shaft sleeve 410 is sealingly fitted with the shooting window 120 through the sealing ring 420. In this solution, the rotating shaft 210 is in direct contact with the sealing shaft sleeve 410, and the sealing ring 420 is sealingly disposed between the sealing shaft sleeve 410 and the shooting window 120, which can prevent the sealing ring 420 from being worn during the rotation of the rotating shaft 210, thereby protecting the sealing ring 420 and further extending the service life of the sealing ring 420. Of course, the sealing shaft sleeve 410 may not be provided, and the rotating shaft 210 is directly sealingly fitted with the shooting window 120 through the sealing ring 420.

[0066] Optionally, the width of the sealing ring 420 may be unchanged in the extending direction of the rotating shaft 210; alternatively, in other embodiments, the sealing ring 420 includes a first annular portion 421, a sleeve structure 422, and a second annular portion 423 that are connected in sequence. The first annular portion 421 is opposite to the second annular portion 423, and the width of the first annular portion 421 (i.e., the diameter of the outer ring surface of the first annular portion 421) and the width of the second annular portion 423 (i.e., the diameter of the outer ring surface of the second annular portion 423) are both greater than the width of the sleeve structure 422 (i.e., the diameter of the outer ring surface of the sleeve structure 422). At least a part of the sleeve structure 422 is disposed in the through hole 121. The first annular portion 421 and the second annular portion 423 are respectively in limit fit with the shooting window 120 in the axial direction of the rotating shaft 210. That is, in the axial direction of the rotating shaft 210, the first annular portion 421 is in limit fit with the inner surface of the shooting window 120, and the second annular portion 423 is in limit fit with the outer surface of the shooting window 120, thereby preventing the sealing ring 420 from moving axially along the rotating shaft 210 relative to the shooting window 120 to improve the stability of the sealing ring 420; and the sealing area between the sealing ring 420 and the shooting window 120 can be increased, thereby improving the sealing performance of the sealing ring 420.

[0067] Optionally, the sealing assembly 400 further includes a sealing pressure ring 430. The wiper assembly 200 is pressed against the second annular portion 423 through the sealing pressure ring 430, and a part of the wiper 220 overlaps the sealing pressure ring 430, thereby further improving the stability of the sealing ring 420.

[0068] Optionally, the diameter of the sealing bushing 410 may be unchanged in the extending direction of the rotating shaft 210; alternatively, in other embodiments, the sealing bushing 410 includes a connected first bushing section 411 and a second bushing section 412. The first bushing section 411 is located in the accommodation cavity of the housing 100. The diameter of the first bushing section 411 is greater than the diameter of the second bushing section 412. A sealing end face 413 is formed at the connection between the first bushing section 411 and the second bushing section 412. A part of the second bushing section 412 is disposed in the through hole 121. The second bushing section 412 is in sealing fit with the shooting window 120 (i.e., the inner wall of the through hole 121) through the sleeve structure 422. The sealing end face 413 of the sealing bushing 410 is in sealing fit with the shooting window 120 (i.e., the inner surface of the shooting window 120) through the first annular portion 421. At this time, the sealing end face 413 of the sealing bushing 410 presses on the first annular portion 421 of the sealing ring 420, which is beneficial to improving the sealing performance between the sealing ring 420 and the inner surface of the shooting window 120, as well as the stability of the sealing ring 420, thereby preventing its movement; and the contact area between the sealing bushing 410 and the sealing ring 420 is also relatively large, which is beneficial to improving the sealing performance between the two.

[0069] In a further optional embodiment, the sealing sleeve 410 further includes a third sleeve section 414 connected to an end of the second sleeve section 412 away from the first sleeve section 411, and the third sleeve section 414 is disposed in the through hole 121. The sealing assembly 400 further includes a sealing pressure ring 430, which includes a connected annular pressure plate 431 and a connecting sleeve 432, a portion of the connecting sleeve 432 is disposed in the through hole 121, and the connecting sleeve 432 is threadedly sleeved on the third sleeve section 414, that is, the connecting sleeve 432 is threadedly connected to the third sleeve section 414, which can further improve the sealing performance of the sealing assembly 400; the annular pressure plate 431 is pressed on the second annular portion 423, thereby improving the sealing performance between the sealing ring 420 and the outer surface of the shooting window 120, and at the same time, the stability of the sealing ring 420 can be further improved. Part of the wiper 220 is superimposed on the annular pressure plate 431, and the two are in contact, and the wiper 220 can rotate relative to the annular pressure plate 431.

[0070] Optionally, the diameter of the second shaft sleeve segment 412 can be equal to the diameter of the third shaft sleeve segment 414; or, in another optional embodiment, the diameter of the second shaft sleeve segment 412 is larger than the diameter of the third shaft sleeve segment 414, and a limiting end face 415 is formed at the connection between the second shaft sleeve segment 412 and the third shaft sleeve segment 414. The connecting sleeve 432 cooperates with the limiting end face 415 in the axial upper limit of the rotating shaft 210 to determine the distance between the annular pressure plate 431 and the end face of the third shaft sleeve segment 414 of the sealing shaft sleeve 410, thereby preventing the annular pressure plate 431 from exerting excessive pressing force on the second annular portion 423 and damaging the sealing ring 420, thereby extending the service life of the sealing ring 420.

[0071] Optionally, the compression amount of the sealing ring 420 can be 25-35% to form a good sealing effect.

[0072] Optionally, the sealing assembly 400 further includes a protective pad 450 , which is stacked on the second annular portion 423 , and the annular pressure plate 431 is pressed against the second annular portion 423 through the protective pad 450 , thereby protecting the second annular portion 423 .

[0073] Optionally, the end faces of the first annular portion 421 and the second annular portion 423 facing away from the sleeve structure 422 are respectively provided with annular ribs 421a, the sealing end face 413 is pressed on the annular rib 421a of the first annular portion 421, and the protective pad 450 is pressed on the annular rib 421a of the second annular portion 423, so that the annular rib 421a is deformed, thereby further improving the sealing performance of the sealing ring 420.

[0074] In another optional embodiment, the inner surface of the sealing sleeve 410 is provided with a receiving groove 416, and the receiving groove 416 extends to the end surface of the sealing sleeve 410 facing the driving member 300. The sealing assembly 400 also includes an oil seal structure 440, which is arranged in the receiving groove 416, that is, the oil seal structure 440 is arranged in the receiving cavity of the housing 100, and the oil seal structure 440 is sealed with the rotating shaft 210. Since the oil seal structure 440 has good sealing performance, wear resistance, corrosion resistance, and convenient installation, the sealing sleeve 410 in this solution is sealed with the rotating shaft 210 through the oil seal structure 440, which is conducive to improving the sealing between the sealing sleeve 410 and the rotating shaft 210. Of course, the oil seal structure 440 may not be provided.

[0075] In a further optional embodiment, the camera further includes an annular baffle 500 and a limiting ring 600. The annular baffle 500 is sleeved on the rotating shaft 210. Optionally, the annular baffle 500 can be sleeved on the rotating shaft 210. In this case, the annular baffle 500 and the rotating shaft 210 are relatively fixed, and the two rotate together. There can be a certain gap between the annular baffle 500 and the oil seal structure 440; or, the annular baffle 500 and the rotating shaft 210 can rotate relative to each other. The rotating shaft 210 is provided with a mounting groove 211, and part of the limiting ring 600 is arranged in the mounting groove 211. In this case, the limiting ring 600 and the rotating shaft 210 are relatively fixed, and the two rotate together. Optionally, the limiting ring 600 can be a retaining spring, which is corrosion-resistant and easy to disassemble and assemble. The limiting ring 600 can cooperate with the oil seal structure 440 in the axial upper limit of the rotating shaft 210 through the annular baffle 500, so as to prevent the oil seal structure 440 from being separated from the receiving groove 416, thereby improving the stability of the oil seal structure 440; and, the rotating shaft 210 can be prevented from axially moving along the through hole 121 during the rotation process. Of course, only one of the annular baffle 500 and the limiting ring 600 can also be provided.

[0076] like Figures 20 to 32As shown, in another alternative embodiment, the windshield wiper 220 includes a bushing 221, a wiper body 222, and an elastic driving member 223. The bushing 221 is connected to the rotating shaft 210. Optionally, the bushing 221 is provided with a connection hole 226, and the bushing 221 is sleeved on the rotating shaft 210 through the connection hole 226. The wiper body 222 is rotatably connected to the bushing 221. One end of the elastic driving member 223 abuts against the wiper body 222, and the other end of the elastic driving member 223 abuts against the bushing 221. The elastic driving member 223 can drive the wiper body 222 to adaptively press against the shooting window 120. That is, by using the elastic potential energy of the elastic driving member 223, during the rotation of the windshield wiper 220 relative to the outer surface of the shooting window 120, the elastic driving member 223 provides a reset torque for the wiper body 222 through its own deformation, so that the wiper body 222 adjusts itself according to the curvature change of the outer surface of the shooting window 120 to ensure that the wiper body 222 always contacts the shooting window 120, thereby improving the wiping performance of the windshield wiper 220. The structure of the windshield wiper 220 in this solution is simple and easy to manufacture.

[0077] Optionally, the elastic driving member 223 can be a torsion spring, which has a large elastic potential energy and is beneficial to stably pressing the wiper body 222 against the shooting window 120.

[0078] In a further alternative embodiment, the bushing 221 is provided with a first avoidance opening 221a, the wiper body 222 is provided with a second avoidance opening 222a, the windshield wiper 220 further includes a rotating shaft 224 and a limiting member 225. The first end of the rotating shaft 224 is provided with a limiting groove 224a, and the second end of the rotating shaft 224 is provided with a limiting flange 224b. The first end of the rotating shaft 224 passes through the opposite side walls of the first avoidance opening 221a and the opposite side walls of the second avoidance opening 222a, so that the wiper body 222 is rotatably connected to the bushing 221. The limiting member 225 is arranged in the limiting groove 224a, and the limiting member 225 and the limiting flange 224b are respectively in axial limiting cooperation with the opposite two surfaces of the bushing 221. The elastic driving member 223 is sleeved on the rotating shaft 224. The second avoidance opening 222a and the first avoidance opening 221a can be arranged side by side; or at least part of the second avoidance opening 222a is located within the first avoidance opening 221a, and at least part of the elastic driving member 223 is arranged within the second avoidance opening 222a. At this time, it is possible to avoid the elastic driving member 223 occupying extra space, make the bushing 221, the elastic driving member 223, and the wiper body 222 arranged more compactly, thereby reducing the size of the windshield wiper 220, and further reducing the area of the shooting window 120 it blocks; in addition, when at least part of the second avoidance opening 222a is located within the first avoidance opening 221a, the size of the bushing 221 is larger, which is not only convenient for connecting with the rotating shaft 210, but also has greater structural strength and better stability.

[0079] Optionally, at least one of the first avoidance opening 221a and the second avoidance opening 222a is provided with a positioning groove 221a1. One end of the elastic driving member 223 can abut against the positioning groove 221a1 of the first avoidance opening 221a, and the other end of the elastic driving member 223 can abut against the positioning groove 221a1 of the second avoidance opening 222a, thereby improving the positioning stability of the elastic driving member 223.

[0080] Optionally, the rotating shaft 224 can be a pin, and of course it can also be other structures, and the embodiments of the present application do not make specific limitations on this.

[0081] Optionally, the limiting member 225 can be a circlip, which has corrosion resistance and is convenient for disassembly and assembly.

[0082] In another alternative embodiment, the wiper body 222 includes a bracket 222b, a protective cover 222c, and a strip-shaped wiping member 222d. Optionally, the strip-shaped wiping member 222d can be a rubber strip, and of course it can also be other structures, and specific limitations are not made here. The bracket 222b is rotatably connected to the bushing 221. The bracket 222b is provided with a second avoidance opening 222a. The first part of the strip-shaped wiping member 222d is arranged inside the protective cover 222c, and the second part of the strip-shaped wiping member 222d is located outside the protective cover 222c and presses against the shooting window 120. At least part of the protective cover 222c is arranged in the accommodating space of the bracket 222b, and the protective cover 222c is rotatably connected to the bracket 222b. Optionally, the rotation center axis of the protective cover 222c can be located in the middle part of the protective cover 222c in its length direction. The protective cover 222c can rotate relative to the bracket 222b around its rotation center axis to make the strip-shaped wiping member 222d fit the shooting window 120. The rotation center axis of the protective cover 222c extends along the width direction of the wiper 220. During the rotation of the wiper 220 relative to the shooting window 120, the elastic driving member 223 acts on the bracket 222b, and the force is transmitted at the rotation connection between the bracket 222b and the protective cover 222c. When the curvature of the outer surface of the shooting window 120 changes, the protective cover 222c rotates relative to the bracket 222b around its rotation center axis, so that the distances between the first part and the second part of the protective cover 222c on the opposite sides of its rotation center axis and the shooting window 120 are basically the same, so that the strip-shaped wiping member 222d acts on the shooting window 120 evenly. At this time, the strip-shaped wiping member 222d can fit the shooting window 120, thereby increasing the wiping area of the strip-shaped wiping member 222d and further improving its wiping efficiency.

[0083] Optionally, on both opposite sides of the protective cover 222c in the length direction of the brush body 222, connecting convex portions 222c1 are provided. On both opposite side walls of the accommodation space of the bracket 222b, mounting holes 222b1 are provided. At least a part of the connecting convex portion 222c1 is inserted into the mounting hole 222b1, and there is a clearance fit between the two. At the same time, the outer surface of the protective cover 222c and the inner surface of the accommodation space of the bracket 222b also have a clearance fit to ensure that the protective cover 222c is rotatably connected to the bracket 222b. It should be noted that the connecting convex portion 222c1 has a certain deformation performance and can deform during the installation process. When at least a part of the connecting convex portion 222c1 is inserted into the mounting hole 222b1, it restores its deformation.

[0084] Optionally, at one end of the protective cover 222c facing away from the bushing 221, a mounting guiding opening 222c2 is provided. The strip-shaped wiping member 222d is partially mounted in the protective cover 222c through the mounting guiding opening 222c2.

[0085] Optionally, the length of the protective cover 222c and the length of the strip-shaped wiping member 222d can both be selected according to the size of the shooting window 120, and the embodiments of the present application do not make specific limitations in this regard.

[0086] Optionally, the wiper 220 and the rotating shaft 210 can be positioned by friction; or, in another alternative embodiment, the wiper 220 is provided with a connecting hole 226. The wiper 220 is sleeved on the rotating shaft 210 through the connecting hole 226. The rotating shaft 210 is provided with a first positioning surface 212, and the connecting hole 226 is provided with a second positioning surface 226a. The first positioning surface 212 and the second positioning surface 226a are positioned and matched in the circumferential direction of the rotating shaft 210, so as to prevent relative rotation between the wiper 220 and the rotating shaft 210 and ensure that the two rotate together.

[0087] Optionally, the number of the first positioning surfaces 212 can be at least one, or the number of the first positioning surfaces 212 is at least two, and the first positioning surfaces 212 are distributed at intervals in the circumferential direction of the rotating shaft 210, thereby improving the positioning stability between the wiper 220 and the rotating shaft 210.

[0088] Optionally, the camera further includes a positioning member 700 provided outside the accommodation cavity. Optionally, the positioning member 700 can be a nut. The positioning member 700 is threadedly connected to the rotating shaft 210. The positioning member 700 is located on the side of the wiper 220 facing away from the shooting window 120. The positioning member 700 and the wiper 220 are positioned and matched in the axial direction of the rotating shaft 210 to prevent the wiper 220 from tilting, so as to ensure that the wiper 220 can be stably pressed on the outer surface of the shooting window 120 and the wiping performance of the wiper 220 is good.

[0089] Based on the camera provided by the embodiments of the present application, the assembly process of its sealing component 400 is as follows:

[0090] The sealing ring 420 is sleeved on the through hole 121 of the shooting window 120. The protective pad 450 is placed above the sealing ring 420. The sealing shaft sleeve 410 is inserted into the through hole 121 from one side of the shooting window 120. The annular pressing plate 431 is pressed onto the protective pad 450. The annular pressing plate 431 and the sealing shaft sleeve 410 are connected by threads. The annular pressing plate 431 compresses the second annular portion 423 of the sealing ring 420 through the protective pad 450 to form a seal. The sealing end face 413 of the sealing shaft sleeve 410 compresses the first annular portion 421 of the sealing ring 420 to form a seal. Then, the oil seal structure 440 is installed into the receiving groove 416 of the sealing shaft sleeve 410, and a seal is formed between the outer ring of the oil seal structure 440 and the sealing shaft sleeve 410.

[0091] Then, the annular baffle 500 and the limit ring 600 are both installed on the rotating shaft 210. The rotating shaft 210 passes through the inner ring of the oil seal structure 440 and extends to the outside of the shooting window 120. A rotating seal is formed between the rotating shaft 210 and the inner ring of the oil seal structure 440. The driving member 300 is fixed to the rotating shaft 210 through a coupling sleeve. On the outside of the shooting window 120, the wiper 220 is installed on the rotating shaft 210, and the wiper 220 and the rotating shaft 210 are fixed together through the positioning member 700, thus completing the assembly of the wiper assembly 200.

[0092] The working principle of the wiper assembly 200 is as follows: The wiper assembly 200 is fixed to the shooting window 120 of the camera through the rotating shaft 210. One end of the rotating shaft 210 realizes the axial locking of the wiper assembly 200 through the positioning member 700, and the other end of the rotating shaft 210 is connected to the output shaft of the driving member 300 to realize the transmission of the swinging torque; the torque generated by the elastic driving member 223 between the shaft sleeve 221 and the brush body 222 of the wiper assembly 200 realizes the reset adjustment. There is a clearance fit between the bracket 222b of the brush body 222 and the protective cover 222c, so that during the rotation of the entire wiper assembly 200, the strip-shaped wiping member 222d fixed on the protective cover 222c can always be adaptively pressed against the outer surface of the shooting window 120 in contact, thereby effectively removing water from the outer surface of the shooting window 120.

[0093] The embodiments of the present application also provide another camera, which includes a shooting window 120 and a wiper assembly 200. A through hole 121 is provided at the edge of the shooting window 120, and the through hole 121 penetrates the shooting window 120. Optionally, the camera further includes a housing 110, and the shooting window 120 is disposed on the housing 110, and the two are hermetically connected to form a closed receiving cavity.

[0094] The wiper assembly 200 includes a rotating shaft 210. One end of the rotating shaft 210 passes through the through hole 121, and the rotating shaft 210 is in sealed cooperation with the shooting window 120. Optionally, the wiper assembly 200 further includes a wiper 220 connected to the rotating shaft 210. The wiper 220 is movably disposed on the outer surface of the shooting window 120, and the rotating shaft 210 is rotatably and sealedly cooperated with the shooting window 120.

[0095] The structure for the above-mentioned sealed cooperation includes a sealing assembly 400. The sealing assembly 400 includes a sealing ring 420, a sealing pressure ring 430 and a sealing bushing 410;

[0096] Among them, the sealing ring 420 includes a first annular portion 421, a sleeve structure 422 and a second annular portion 423 connected in sequence. The first annular portion 421 is opposite to the second annular portion 423. Optionally, the widths of both the first annular portion 421 and the second annular portion 423 are greater than the width of the sleeve structure 422. At least part of the sleeve structure 422 is disposed in the through hole 121. The first annular portion 421 and the second annular portion 423 are respectively in limit cooperation with the shooting window 120 in the axial direction of the rotating shaft 210, so as to prevent the sealing ring 420 from moving axially relative to the shooting window 120 along the rotating shaft 210, thereby improving the stability of the sealing ring 420; and the sealing area between the sealing ring 420 and the shooting window 120 can be increased, thereby improving the sealing performance of the sealing ring 420.

[0097] The sealing pressure ring 430 includes a connected annular pressing plate 431 and a connecting sleeve 432. The inner wall of the connecting sleeve 432 has internal threads. Part of the connecting sleeve 432 is disposed in the through hole 121, and the annular pressing plate 431 presses on the second annular portion 423, thereby improving the sealing performance between the sealing ring 420 and the outer surface of the shooting window 120, and at the same time, the stability of the sealing ring 420 can be further improved.

[0098] The sealing bushing 410 includes an external thread, a sealing end face 413 and a limiting end face 415, and both the sealing end face 413 and the limiting end face 415 form stepped faces. Optionally, the sealing bushing 410 includes a first bushing section 411, a second bushing section 412 and a third bushing section 414 connected in sequence. The first bushing section 411 is located in the accommodation cavity, the diameter of the first bushing section 411 is greater than that of the second bushing section 412, and a sealing end face 413 is formed at the connection between the first bushing section 411 and the second bushing section 412. A part of the second bushing section 412 and the third bushing section 414 are arranged in the through hole 121. The second bushing section 412 is in sealing fit with the shooting window 120 (i.e., the inner wall of the through hole 121) through a sleeve structure 422. The sealing end face 413 of the sealing bushing 410 is in sealing fit with the shooting window 120 (i.e., the inner surface of the shooting window 120) through a first annular portion 421. At this time, the sealing end face 413 of the sealing bushing 410 presses on the first annular portion 421 of the sealing ring 420, which is beneficial to improving the sealing performance between the sealing ring 420 and the inner surface of the shooting window 120, as well as the stability of the sealing ring 420, thereby preventing it from moving; and, the contact area between the sealing bushing 410 and the sealing ring 420 is also relatively large, which is beneficial to improving the sealing performance between the two; the diameter of the second bushing section 412 is greater than that of the third bushing section 414, and a limiting end face 415 is formed at the connection between the second bushing section 412 and the third bushing section 414. The connecting sleeve 432 and the limiting end face 415 are in limiting fit in the axial direction of the rotating shaft 210 to determine the distance between the annular pressing plate 431 and the end face of the third bushing section 414 of the sealing bushing 410, so as to prevent the pressing force of the annular pressing plate 431 on the second annular portion 423 from being too large and damaging the sealing ring 420, thereby extending the service life of the sealing ring 420.

[0099] The camera in the embodiment of the present application is configured as:

[0100] The inner wall of the through hole 121 of the shooting window 120 receives the sealing ring 420. The sealing bushing 410 is inserted through the shooting window 120 in the thickness direction from the inside to the outside (here, from the inside to the outside specifically refers to from the inside of the accommodation cavity to the outside of the accommodation cavity), and the sealing pressure ring 430 is inserted through the shooting window 120 in the thickness direction from the outside to the inside (here, from the outside to the inside specifically refers to from the outside of the accommodation cavity to the inside of the accommodation cavity), so that the external thread of the sealing bushing 410 is locked with the internal thread of the sealing pressure ring 430. The connecting sleeve 432 abuts against the limiting end face 415, the annular pressing plate 431 abuts against the second annular portion 423, and the sealing end face 413 abuts against the first annular portion 421, thereby forming the above-mentioned sealing fit to improve the sealing performance of the sealing assembly 400.

[0101] In the embodiment of the present application, by opening a through hole 121 at the edge of the shooting window 120, the rotation shaft 210 of the wiper assembly 200 is moved from the housing 110 of the camera to the shooting window 120, so as to shorten the distance between the rotation shaft 210 and the central area of the shooting window 120. At this time, the length of the wiper 220 can be reduced, thereby improving the scraping performance of the wiper 220. Therefore, the embodiment of the present application can solve the problem that the distance between the rotation shaft 210 of the wiper assembly 200 of the current camera and the central area of the shooting window 120 is relatively long, resulting in poor scraping performance of the wiper assembly 200.

[0102] The embodiments of the present application have been described above in conjunction with the accompanying drawings. However, the present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative and not restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them fall within the protection scope of the present application.
