TECHNICAL FIELD

[0001] The present application relates to the technical field of camera, more particularly, to a lens protection cover and a camera assembly. BACKGROUND

[0002] ADAS (Advanced Driver Assistance Systems) is also known as automatic driving assistance system, which is an important achievement of modern automobile technology. The ADAS system uses various sensors (such as millimeter wave radar, laser radar, front-view camera and satellite navigation, etc.) installed on the vehicle to perceive the surrounding environment, collect data, and identify, detect and track static and dynamic objects, so as to realize various functions. For example: lane departure warning, lane keeping assistance, adaptive cruise control, forward collision prevention, automatic parking, blind spot monitoring, driver fatigue warning, adaptive light control, etc.

[0003] With the development of ADAS technology, the resolution of the front-view camera is getting higher and higher, and the front-view camera lens is protruding from the lens barrel, which is easy to rub and collide with other external objects during transportation and production, causing damage to the lens.

[0004] In the prior art, in order to prevent external objects from rubbing and colliding with the lens and causing damage to the lens, a lens protection cover is usually buckled on the front-view camera to protect the lens of the front-view camera. The lens protection cover is generally the same color as the front-view camera, and the operator often forgets to remove the lens protection cover when assembling the front-view camera to the vehicle body, resulting in rework.

[0005] Therefore, how to prevent missing the lens protection cover during the assembly of the camera is a problem to be solved by those skilled in the art. Utility model content

[0041] The core of the present application is to provide a lens protection cover to prevent the lens protection cover from being disassembled by mistake when assembling the camera;

[0042] Another purpose of the present application is to provide a camera assembly with the above lens protection cover.

[0043] Hereinafter, the embodiments will be described with reference to the drawings. In addition, the embodiments shown below do not have any limiting effect on the application content recited in the claims. In addition, the entire content of the configuration represented in the following embodiments is not limited to what is necessary as a solution to the application recited in the claims. It should be noted that only the parts related to the application are shown in the drawings for ease of description. In the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0044] As Figure 1 and Figure 2As shown, the lens protection cover disclosed in the embodiments of the present application comprises a buckling cover body 100 and a leakage-proof dismounting body 200. One end of the buckling cover body 100 is a buckling opening for inserting the lens end of the camera. The inner diameter of the buckling opening can be designed to be slightly larger than the outer diameter of the lens barrel of the camera, so as to facilitate the insertion of the camera into the buckling opening. It should be noted that a guide flared portion can also be provided at the end of the buckling opening, which can also facilitate the fitting of the buckling cover body 100 on the camera.

[0045] The inner wall of the buckling cover body 100 is provided with a clamping portion for clamping the outer wall of the camera. The clamping portion protrudes from the inner wall of the buckling cover body 100, that is, after the camera is inserted into the buckling cover body 100, the structure actually cooperating with the outer wall of the camera is the clamping portion. The buckling cover body 100 can be a plastic suction forming structure, and the clamping portion is directly formed on the buckling cover body 100. In order to reduce the thickness at the position of the clamping portion, the clamping portion can protrude from the outer wall to the inner wall of the buckling cover body 100, that is, the clamping portion protrudes into the cavity of the buckling cover body 100, and a corresponding recess is formed on the outside of the buckling cover body 100.

[0046] In order to ensure that the clamping portion has sufficient clamping force on the camera and prevent the lens protection cover from falling off the camera, in the embodiments, the clamping portion can be a plurality of clamping portions arranged at intervals in the circumferential direction. The specific number of clamping portions can be selected by those skilled in the art according to requirements. Each clamping portion can be uniformly arranged along the circumferential direction of the inner wall of the buckling cover body 100, so as to output a more uniform clamping force on the camera in the circumferential direction.

[0047] It should be noted that since each clamping portion needs to be interference-fitted with the outer wall of the lens barrel of the camera, in order to cooperate the camera with the clamping portion. In other words, in order to facilitate the insertion of the camera into the space surrounded by the clamping portion, in the embodiments, a guide structure such as a chamfer structure can be provided at the end of the clamping portion facing the buckling opening, so that the camera can be easily inserted into the space surrounded by the clamping portion under the action of the guide structure, thereby improving the convenience of installation.

[0048] The leakage-proof dismounting body 200 is arranged on the buckling cover body 100, and when the camera with the lens protection cover is installed on the vehicle body, the leakage-proof dismounting body 200 can interfere with other objects of the vehicle body. It should be noted that the position of the leakage-proof dismounting body 200 on the buckling cover body 100 is not limited, as long as when the camera is installed, if the lens protection cover is removed, the leakage-proof dismounting body 200 will interfere with other parts of the vehicle body. The position of the leakage-proof dismounting body 200 on the buckling cover body 100 should be designed according to the corresponding vehicle model, and designed according to the environment near the camera installation position of the vehicle model, so as to cause interference.

[0049] It should be noted that the leak-proof disassembly body 200 and the buckling cover body 100 can be formed by plastic injection molding, that is, the lens protection cover is an integrated structure. The leak-proof disassembly body 200 can be a closed structure, that is, the cavity surrounded by the buckling cover body 100 cannot communicate with the outside through the leak-proof disassembly body 200, so that after the lens protection cover is installed on the camera, external dust cannot enter the cavity of the buckling cover body 100 through the leak-proof disassembly body 200 to contaminate the lens of the camera, causing the lens of the camera to be dirty.

[0050] The leak-proof disassembly body 200 can be designed as a gripping handle structure, that is, its shape is designed as a structure convenient for an operator to grip, so that when the lens protection cover is assembled on the camera, the operator can grip the leak-proof disassembly body 200 with his hand, align the buckling opening with the camera, and then push the lens protection cover towards the camera until the lens protection cover is sleeved on the camera. When disassembling the lens protection cover, the operator can grip the leak-proof disassembly body 200 with his hand to pull the lens protection cover out of the camera.

[0051] The lens protection cover provided by the present application can buckle the buckling cover body 100 on the lens end of the camera through the buckling opening to protect the lens of the camera. The inner wall of the buckling cover body 100 is provided with a clamping portion for clamping the outer wall of the camera, so that when the buckling cover body 100 is buckled on the camera, the inner wall of the buckling cover body 100 does not contact the outer wall of the camera, and only plays a role of isolation and shielding from the outside. During assembly, only the clamping portion contacts the outer wall of the camera, which has a smaller contact area, so that the friction force during assembly can be reduced under the premise of ensuring assembly reliability, and the lens protection cover is more convenient to assemble and disassemble. When the buckling cover body 100 is buckled on the camera, the clamping portion is extruded by the camera, which will cause the clamping portion to deform outward, and the extrusion force generated by the deformation will cause the clamping portion to tightly fit with the outer wall of the camera, so that there is a suitable assembly and disassembly force during assembly and disassembly.

[0052] The buckling cover body 100 is provided with the leak-proof disassembly body 200, which can interfere with other objects of the vehicle body, so that when the camera is assembled on the vehicle body, only by removing the lens protection cover can the camera be smoothly assembled on the vehicle body, otherwise the installation of the camera cannot be completed due to the interference of the leak-proof disassembly body 200. The present application can prevent rework caused by missing the lens protection cover.

[0053] In an embodiment of the present application, the buckling opening is located at the first end of the buckling cover 100, the anti-leakage disassembly body 200 is arranged at the second end of the buckling cover 100, and the first end and the second end of the buckling cover 100 are opposite ends. That is, in this embodiment, the buckling opening and the anti-leakage disassembly body 200 are located at the two ends of the buckling cover 100, respectively. In this way, when the operator holds the anti-leakage disassembly body 200 and installs the lens protection cover, only needs to apply a pushing force along the axis direction of the lens protection cover, and the installation of the lens protection cover is more easily realized

[0054] In an embodiment of the present application, the clamping portion is an arc surface structure protruding in the axial direction of the buckling cover 100. Specifically, the clamping portion can be a cylindrical arc surface structure, or other curved surface. It can be understood by those skilled in the art that the arc surface structure is in line contact with the outer wall of the lens barrel of the camera, and the friction is small, so that it is more labor-saving when buckling the lens protection cover. Moreover, the clamping portion is designed as an arc surface structure, which is more easily deformed by the extrusion of the camera lens barrel, thereby ensuring a better clamping force on the camera.

[0055] In order to improve the use range of the lens protection cover, in an embodiment of the present application, the buckling cover 100 comprises a plurality of protection portions, and each protection portion is arranged in sequence from the end close to the buckling opening to the end away from the buckling opening. Each protection portion is used for cooperating with a camera of different size, so that the lens protection cover can be covered on a camera of different size.

[0056] In the direction from the end close to the buckling opening to the end away from the buckling opening, the size of the camera cooperated by each protection portion decreases in sequence, that is, the inner diameter of the protection portion close to the buckling opening is larger, and the inner diameter of the protection portion away from the buckling opening is smaller, that is, the depth of the camera of larger size inserted by the buckling opening is shallower, and the depth of the camera of smaller size inserted by the buckling opening is deeper.

[0057] The inner wall of each protection portion is provided with a clamping portion, so as to clamp different cameras. When assembling a large-size camera, the protection portion for cooperating with a small-size camera does not work and does not contact the large-size camera; when assembling a small-size camera, the small-size camera passes through the protection portion for cooperating with a large-size camera and cooperates with the small-size protection portion, thereby playing a connecting protection role. The lens protection cover disclosed in the embodiment of the present application has the advantages of simple structure, low price, and can simultaneously protect multiple cameras.

[0058] In this embodiment, the cover 100 includes two protection parts. For ease of understanding, the two protection parts are defined as a first protection part 110 and a second protection part 120 along a direction from an end close to the fastening opening to an end away from the fastening opening. An inner wall of the first protection part 110 is defined as a first protection inner wall 111, and an inner wall of the second protection part 120 is defined as a second protection inner wall 121.

[0059] A clamping part provided on the first protection inner wall 111 of the first protection part 110 is defined as a first clamping part 112, and a clamping part provided on the second protection inner wall 121 of the second protection part 120 is defined as a second clamping part 122.

[0060] The inner diameter of the first protection part 110 is greater than the inner diameter of the second protection part 120. The first clamping part 112 is used to clamp a first camera, and the second clamping part 122 is used to clamp a second camera. The outer diameter of the first camera is greater than the outer diameter of the second camera. The outer wall of the lens barrel of the first camera is in clearance fit with the first protection inner wall 111 and in interference fit with the first clamping part 112. The outer wall of the lens barrel of the second camera is in clearance fit with the second protection inner wall 121 and in interference fit with the second clamping part 122.

[0061] It should be noted that the number of protection parts is not limited to two in the above embodiment. Those skilled in the art can design more protection parts according to requirements, as long as each protection part is arranged in a descending order along a direction from an end close to the fastening opening to an end away from the fastening opening.

[0062] In an embodiment of the present application, the first protection part 110 includes a first thrust limiting part 113, which is used to limit abutment with the first camera. When the lens protection cover is applied to the first camera (the camera cooperating with the first protection part 110 is defined as the first camera), the lens protection cover is sleeved on the first camera from the fastening opening, and the lens protection cover is continuously pushed along the extension direction of the first camera until the first camera abuts against the first thrust limiting part 113. At this time, the first clamping part 112 is clamped on the outer wall of the lens barrel of the first camera. When the first camera abuts against the first thrust limiting part 113, the lens protection cover cannot be continuously pushed. That is, when the operator installs the lens protection cover on the first camera, the lens protection cover can be stopped when it cannot be continuously pushed. At this time, it indicates that the lens protection cover has been installed in place.

[0063] The first thrust limiting portion 113 can be designed as a stepped surface at the transition of the first protective inner wall 111 and the second protective inner wall 121, as understood by those skilled in the art. That is, the first protective inner wall 111 and the second protective inner wall 121 have different diameters, and the diameter of the first protective inner wall 111 is greater than that of the second protective inner wall 121. Therefore, a stepped surface is formed at the transition of the two, which is the end surface of the second protective inner wall 121 facing the clamping opening.

[0064] It should be noted that the first thrust limiting portion 113 is provided on the first protective inner wall 111, and is not limited to the end surface of the second protective inner wall 121.

[0065] Similarly, the second clamping portion 122 can also include a second thrust limiting portion 123 for abutting against the second camera. When the lens protection cover is applied to the second camera (the camera cooperating with the first protective portion 110 is defined as the second camera), the clamping opening is sleeved into the second camera, and the lens protection cover is continuously pushed along the extension direction of the second camera until the second camera abuts against the second thrust limiting portion 123. At this time, the second clamping portion 122 is clamped to the outer wall of the lens barrel of the second camera. When the second camera abuts against the second thrust limiting portion 123, the lens protection cover cannot be continuously pushed. That is, when the operator installs the lens protection cover on the second camera, the lens protection cover can be stopped when it cannot be continuously pushed, which indicates that the lens protection cover has been installed in place.

[0066] As understood by those skilled in the art, the second thrust limiting portion 123 can be designed as a stepped surface provided on the second protective inner wall 121 away from one end of the second protective inner wall 121. That is, a structure with a smaller aperture can be provided on the end of the second protective inner wall 121 away from the clamping opening, so that the stepped surface is formed thereon for limiting the cooperation depth of the second camera.

[0067] Since the current cameras all have lens glasses protruding outward, in order to prevent the lens protection cover from colliding with the outwardly protruding lens glass, in an embodiment of the present application, a lens avoiding portion 300 is provided between the leakage prevention body 200 and the clamping cover body 100, and the lens avoiding portion 300 communicates with the clamping cover body 100 and is used for avoiding the outwardly protruding lens of the camera. That is, the protective portion cooperating with the smallest size camera cannot be directly closed at the end away from the clamping opening, and a transition cavity portion (i.e. the lens avoiding portion 300) should be provided, which can prevent the smallest size camera from contacting the solid portion of the lens protection cover after being installed in place. Since the outwardly protruding lens glass of the camera has a spherical structure, the side wall of the lens avoiding portion 300 can also be designed as a spherical structure to prevent stress concentration and facilitate demolding.

[0068] It should be noted that the lens protection cover is designed for the lens avoidance part 300 of the smallest size camera, because in addition to the smallest size camera, the inner wall of the protection part adjacent to the end away from the buckling opening can be used as an avoidance space for other cameras. In other words, in addition to the smallest size camera, other cameras do not have the risk of the lens glass being knocked outwards.

[0069] The application further discloses a camera assembly, which comprises a camera and a lens protection cover buckled to the lens end of the camera, and the lens protection cover is the lens protection cover disclosed in the above embodiment. Since the lens protection cover has all the technical effects of the lens protection cover, this document will not be repeated here.
