[0046] The existing camera 200 is fixed on the top surface of the mounting carrier through the mounting frame 100; the existing camera 200 is fixed on the side wall surface of the mounting carrier through the mounting frame 100. In both of the existing methods, one end of the mounting frame 100 is fixed to the mounting carrier, and the other end of the mounting frame 100 is fixed to the top surface or the bottom surface of the barrel camera 200. Since the mounting frame 100 and the camera 200 have only one contact surface, and the contact surface is far away from the center of gravity of the camera 200, when the camera 200 is working, it is easy to cause the vibration of the camera 200 to intensify, affecting the image stability.

[0047] Reference Figures 1 to 3 The present invention provides a camera device 1000 with a shock-absorbing structure. In one embodiment, the camera device 1000 with a shock-absorbing structure includes a camera 200 and a mounting frame 100. The mounting frame 100 includes a base 110 and a first mounting ear 120 that are integrally connected, and a second mounting ear 130 that is detachably connected to the base 110. The first mounting ear 120 and the second mounting ear 130 are arranged opposite to each other, and the first mounting ear 120 and the second mounting ear 130 are provided with a first connecting structure (not marked in the figure) on the opposite surfaces of the first mounting ear 120 and the second mounting ear 130. The camera 200 is fixed to the mounting frame 100 through flexible cooperation between the first connecting structure and the second connecting structure. The camera device 1000 with a shock-absorbing structure is fixed to a mounting surface through the surface of the base 110 that is away from the camera 200. The central axes of the two second connecting structures are arranged in a colinear manner, and the center of gravity of the camera 200 is located on the central axes of the two second connecting structures.

[0048] The camera device 1000 with a shock-absorbing structure of the technical solution of the present invention comprises a camera 200 and a mounting frame 100, wherein the base 110, the first mounting ear 120, and the second mounting ear 130 of the mounting frame 100 enclose a mounting space for mounting the camera 200, and the two opposite sides of the camera 200 are provided with a second connection structure, and the center of gravity of the camera 200 is between the two second connection structures. Thus, in the technical solution of the present invention, two contact surfaces are formed between the camera 200 and the mounting frame 100, and the center of gravity of the camera 200 is also between the two force-bearing contact surfaces. Thus, the center of gravity position of the camera 200 is closer to the force-bearing contact point between the mounting frame 100 and the camera 200 compared with the existing installation method, which can effectively avoid the vibration generated when the camera 200 is working and reduce its influence on the image stability of the camera 200. In addition, the first connection structure and the second connection structure are flexibly connected, which can further reduce the vibration transmission between the camera 200 and the mounting frame 100 and improve the shock-absorbing effect.

[0049] In this embodiment, the base 110 and the first mounting ear 120 of the mounting frame 100 are an integrated structure, which can reduce the number of parts, reduce the assembly process of the parts in the camera device 1000 with a shock-absorbing structure, avoid assembly errors between the base 110 and the first mounting ear 120, and improve the structural strength between the base 110 and the first mounting ear 120. The second mounting ear 130 and the base 110 can be detachably connected by screws or by buckles, which is not limited here.

[0050] The mounting frame 100 formed by the base 110, the first mounting ear 120 and the second mounting ear 130 has a U-shaped structure, and the mounting space is also a U-shaped mounting space with an opening. The second mounting ear 130 is detachably connected to the base 110 to facilitate the installation of the camera 200, and it is also convenient to remove the camera 200 from the mounting frame 100 for maintenance.

[0051] During installation, the surface of the base 110 facing away from the camera 200 is fixed to the installation surface, and then the camera 200 is connected to the first installation ear 120, and then the second installation ear 130 and the base 110 are locked, so as to achieve the installation and fixation of the camera 200. It can be understood that the installation surface can be the top surface or side wall surface of the wall, or the installation surface can also be the surface of other installation carriers, which is not limited here.

[0052] In one embodiment, the camera 200 is a cylindrical model, and a second connecting structure is provided on two opposite side walls of the camera 200. The second connecting structure is roughly located in the middle position between the front and rear ends of the cylinder, and also in the middle position between the bottom and top surfaces of the camera 200. The extension lines of the central axes of the two second connecting structures can pass through the center of gravity of the camera 200, so that the center of gravity of the camera 200 is close to the two second connecting structures on the surface of the camera 200; that is, the connection force points between the camera 200 and the mounting frame 100 are located on both sides of the center of gravity of the camera 200, which can effectively avoid the situation where the camera 200 is intensified due to the center of gravity of the camera 200 being far away from the connection force points between the camera 200 and the mounting frame 100 when working, thereby effectively avoiding the impact of the intensified vibration on the image of the camera 200.

[0053] In one embodiment, the first connection structure and the second connection structure have a variety of matching forms, such as an axis and hole structure, a mortise and tenon structure, etc. As long as the connection structure between the camera 200 and the mounting bracket 100 can be realized, it is not limited here.

[0054] Please refer to Figures 1 to 6 In one embodiment of the present invention, the first connection structure is a connection hole 131 recessed in the first mounting ear 120 and the second mounting ear 130, and the second connection structure is a connection shaft 211 protruding on two opposite sides of the camera 200. In the technical solution of this embodiment, the first mounting ear 120 and the second mounting ear 130 are provided with connection holes 131 on two opposite surfaces, and the connection holes 131 are formed as the first connection structure, and the connection holes 131 are blind holes. The connection shaft 211 is formed as the second connection structure, and the connection shaft 211 and the camera 200 can be an integral structure, the outer wall of the connection shaft 211 is matched with the inner wall surface of the connection hole 131, and the end of the connection shaft 211 is in contact with the bottom wall of the connection hole 131, so as to limit the spatial position of the camera 200 and improve the reliability of the assembly between the camera 200 and the mounting bracket 100.

[0055] In another embodiment of the present invention, the first connection structure is a connection shaft 211 protruding from the surface of the first mounting ear 120 and the second mounting ear 130 , and the second connection structure is a connection hole 131 recessed on two opposite side surfaces of the camera 200 .

[0056] In another technical solution of the present embodiment, a connecting shaft 211 may be protrudingly provided on the mounting frame 100, a connecting column (not shown in the figure) may be protrudingly provided on the surface of the camera 200, and a connecting hole 131 may be recessed on the end face of the connecting column. In this way, the mounting frame 100 and the camera 200 may still be connected by means of a shaft and a hole.

[0057] Please refer to Figures 3 to 5 In one embodiment of the present invention, the outer diameter of the connecting shaft 211 gradually decreases from a position away from its end face toward its end face, and the inner diameter of the connecting hole 131 gradually increases from a position away from its opening toward its opening, so that the side wall surface of the connecting shaft 211 and the inner wall surface of the connecting hole 131 fit each other to form a self-locking structure.

[0058] In the technical solution of this embodiment, the self-locking structure formed between the outer diameter of the connecting shaft 211 and the inner diameter of the connecting hole 131 is a wedge-shaped structure with an inclination, please refer to Figure 6 The outer diameter of the connecting shaft 211 decreases from the end close to the camera 200 to the end far away from the camera, and the connecting shaft 211 is in a wedge shape that is inclined and becomes smaller; correspondingly, the inner diameter of the connecting hole 131 gradually increases toward the direction of the camera 200. When the camera 200 and the mounting bracket 100 are fixed, the two ends of the connecting shaft 211 are fixed, and the outer wall of the connecting shaft 211 and the inner wall of the connecting hole 131 are also pressed and matched with each other, so that the camera 200 can be tightly connected with the first mounting ear 120 and the second mounting ear 130 to form a self-locking, prevent the body of the camera 200 from rotating, reduce the movement in the radial direction, thereby improving the reliability of the fixation between the entire mounting bracket 100 and the camera 200 and reducing vibration.

[0059] Please refer to Figure 4 In one embodiment of the present invention, the angle formed by the side wall surface of the connecting shaft 211 and the axis of the connecting shaft 211 is θ, and the angle value of θ is related to the friction coefficient between the connecting shaft 211 and the surface of the connecting hole 131.

[0060] In this embodiment, the wedge-shaped connecting shaft 211 and the wedge-shaped connecting hole 131 are adapted to each other, which can be understood as the angle formed by the inner wall surface of the connecting hole 131 and its central axis is equal to θ. The angle value of θ is designed according to the friction coefficient of the connecting shaft 211 and the surface forming the connecting hole 131. Generally, the greater the friction coefficient of the two surfaces, the smaller the allowable wedge angle θ can be.

[0061] For example, in one embodiment, the material of the wedge-shaped connecting shaft 211 and the wedge-shaped connecting hole 131 are both metal, and the metal surface is polished. At this time, the friction coefficient between the surface of the wedge-shaped connecting shaft 211 and the wedge-shaped connecting hole 131 is small, and the larger the required angle θ, the value of θ should be at least greater than or equal to 10°, such as 12°, 15°, 20°, etc.

[0062] In another embodiment, the material of the wedge-shaped connecting shaft 211 and the wedge-shaped connecting hole 131 are both plastic materials, and the surfaces of the connecting shaft 211 and the connecting hole 131 are not polished. At this time, the friction coefficient of the surfaces of the connecting shaft 211 and the connecting hole 131 is relatively large, and the corresponding required angle θ is smaller, and the value of θ should be less than 10°, such as 9°, 8°, 6°, 5°, etc.

[0063] The wedge-shaped connecting shaft 211 must not only satisfy the function of realizing self-locking, but also ensure the connection strength of the connecting shaft 211 itself. The wedge-shaped connecting shaft 211 and the wedge-shaped connecting hole 131 must realize self-locking. In one embodiment, the connecting shaft 211 can also be divided into a fixed section and a wedge-shaped section connected to each other, wherein the outer diameter of the fixed section remains unchanged, and the outer diameter of the fixed section is greater than the maximum outer diameter of the wedge-shaped section, the fixed section is arranged close to the camera 200, and the wedge-shaped section is connected to the end of the fixed section; correspondingly, the inner wall surface of the connecting hole 131 is also formed into a structure of two sections with different inner diameters adapted to the connecting shaft 211, so that the connection strength between the connecting shaft 211 and the connecting hole 131 can be ensured, and the size design of the wedge-shaped self-locking between the connecting shaft 211 and the connecting hole 131 can also be affected. At the same time, a limit platform is formed between the fixed section and the wedge-shaped section of the connecting shaft 211, and the surfaces of the first mounting ear 120 and the second mounting ear 130 can also abut against the surface of the limit platform for limiting.

[0064] Reference Figure 3 and Figure 5 In one embodiment of the present invention, a through hole 133 is further provided on the first mounting ear 120 and the second mounting ear 130, and the through hole 133 passes through the first connecting structure. The second connecting structure is also provided with a threaded hole 213, and the camera 200 is fixed to the mounting bracket 100 by locking the screws with the through hole 133 and the threaded hole 213.

[0065] In the technical solution of the present embodiment, the aperture of the through hole 133 is smaller than the aperture of the connecting hole 131, and the through hole 133 is connected to the connecting hole 131. In this way, a screw can be used to pass through the first mounting ear 120 / the second mounting ear 130, and the connecting shaft 211 can be locked and connected to the first mounting ear 120 / the second mounting ear 130. In this way, the locking force of the screw squeezes the first mounting ear 120 and the second mounting ear 130 in the axial direction, thereby ensuring that the end of the connecting shaft 211 abuts against the bottom wall of the connecting hole 131, thereby improving the reliability of the connection between the connecting shaft 211 and the connecting hole 131.

[0066] In one embodiment, since the first connection structure and the second connection structure are flexibly connected, a rigid connection between the connection shaft 211 and the connection hole 131 can be avoided, the vibration transmission between the camera 200 and the mounting bracket 100 can be reduced, and the stability of the fixing of the camera 200 can be improved. Specifically, the flexible connection between the two can be that the connection shaft 211 and the connection hole 131 are both directly flexible structures. For example, the end surface of the connection shaft 211 can be flexible, or the end surface of the connection hole 131 can be flexible, or the first connection structure and the second connection structure are both rigid, and a flexible structure can be clamped between the first connection structure and the second connection structure.

[0067] Reference Figure 3 and Figure 5 In one embodiment of the present invention, a first flexible pad 140 is further provided in the connection hole 131, the end surface of the connection shaft 211 abuts against the first flexible pad 140, the maximum outer diameter of the first flexible pad 140 is smaller than the minimum outer diameter of the connection shaft 211, and the first flexible pad 140 is further provided with a through hole 141. In this embodiment, the thickness of the first flexible pad 140 may be between 2 and 5 mm, the first flexible pad 140 may be a rubber pad, a silicone pad, a plastic pad or other flexible pads, the outer diameter of the first flexible pad 140 is smaller than the minimum outer diameter of the connection shaft 211, so as to ensure that the first flexible pad 140 can be accommodated in the connection hole 131, and avoid the outer diameter of the first flexible pad 140 being too large, resulting in a gap between the outer wall of the connection shaft 211 and the inner wall of the connection hole 131, and the outer wall of the connection shaft 211 cannot be fitted with the inner wall of the connection hole 131, resulting in radial movement. There is a certain amount of compression between the first flexible pad 140 and the connecting shaft 211 and the connecting hole 131. After the screws are tightened, the reliability of the connection between the camera 200 and the mounting bracket 100 can be guaranteed to avoid a connection void between the two. At the same time, the rigid connection is also converted into a flexible connection, thereby reducing the vibration transmission between the mounting bracket 100 and the camera 200 and improving the shock absorption effect.

[0068] Please refer to Figure 3 , Figure 5 and Figure 6In one embodiment of the present invention, a clamping platform 111 is provided on the surface of the base 110 facing the second mounting ear 130, a clamping block 135 is formed on the surface of the second mounting ear 130 facing the base 110, a second flexible pad 150 is sandwiched between the clamping platform 111 and the clamping block 135, a fixing hole 113 is provided on the clamping platform 111, a mounting hole 137 is provided on the clamping block 135, the second mounting ear 130 is fixed to the base 110 by screws, the fixing holes 113 and the mounting holes 137, a positioning structure (not shown in the figure) is formed between the base 110 and the second mounting ear 130, a positioning column 139 and a positioning hole 115 of the positioning structure, the positioning column 139 is provided on one of the base 110 and the second mounting ear 130, the positioning hole 115 is provided on the other of the base 110 and the second mounting ear 130, and the second flexible pad 150 is further provided with a second clearance hole 153 for the positioning column 139 to pass through.

[0069] In one embodiment of the present invention, the shapes of the clamping platform 111 formed on the base 110 and the clamping block 135 on the second mounting ear 130 are adapted to each other. When the clamping platform 111 and the clamping block 135 cooperate with each other, the second mounting ear 130 has been fixed to the base 110, and then the second mounting ear 130 is locked on the base 110 through the cooperation between the screw and the fixing hole 113 and the mounting hole 137.

[0070] There are many shapes for the card platform 111 and the card block 135 to match. For example, in one embodiment, the card platform 111 is L-shaped, and the card block 135 is formed into an inverted L structure; in another embodiment, the card platform 111 can be an inverted L shape, and the card block 135 is formed into an L structure; as long as the card platform 111 can match the card block 135, the shapes of the two are not limited. By providing the card platform 111 and the card block 135, the assembly efficiency and assembly accuracy between the second mounting ear 130 and the base 110 can be effectively improved.

[0071] Reference Figure 6In one embodiment of the present invention, a positioning structure is formed between the base 110 and the second mounting ear 130, which is a positioning hole 115 and a positioning column 139. The positioning hole 115 can be set on the base 110, and the second mounting ear 130 is correspondingly provided with a positioning column 139; in another embodiment, the positioning hole 115 can be set on the second mounting ear 130, and the base 110 is correspondingly provided with a positioning column 139.

The second flexible pad 150 is also provided with a first clearance hole 151 at the position corresponding to the screw, and a second clearance hole 153 is provided at the position corresponding to the positioning column 139, so that the screw and the positioning column can smoothly pass through the second flexible pad 150. The second flexible pad 150 can transform the rigid connection between the second mounting ear 130 and the base 110 into a flexible connection, thereby avoiding the transmission of vibration between the second mounting ear 130 and the base 110, and further reducing the impact of vibration on the camera 200.

[0073] Reference Figure 1 and Figure 3 In one embodiment of the present invention, a third flexible pad 160 is further provided on the surface of the base 110 away from the camera 200. In this embodiment, the third flexible pad 160 may be one or more, and the third flexible pad 160 may be a rubber pad, a silicone pad, a plastic pad or other flexible pads; the third flexible pad 160 corresponds to the position of the base 110 and the mounting surface screw, and the third flexible pad 160 can convert the rigid connection between the mounting frame 100 and the mounting surface into a flexible connection, which improves the reliability of the connection between the two on the one hand, and reduces the vibration transmission between the mounting surface and the mounting frame 100 on the other hand, further improving the stability of the camera 200.

[0074] Please refer to Figure 2In one embodiment of the present invention, the surface of the base 110 facing away from the camera 200 is connected with an elastic bracket 170, and the base 110 is fixed by fixing the elastic bracket 170. In this embodiment, the elastic bracket 170 can be an elastic steel bracket, and the elastic bracket 170 includes a first fixed part (not shown in the figure), an elastic structure (not shown in the figure) and a second fixed part (not shown in the figure) connected to each other. The first fixed part is fixed to the base 110 by screws, and the second fixed part is fixed to the mounting surface by screws. The elastic structure includes a plurality of elastic steel wires, and the elastic steel wires can absorb the vibration between the first fixed part and the second fixed part, reduce the vibration transmission between the mounting surface and the mounting frame 100, and further improve the stability of the camera 200.

[0075] In another embodiment, the third flexible pad 160 and the elastic bracket 170 can also be provided at the same time, wherein the first fixing portion of the elastic bracket 170 is fixed to the surface of the third flexible pad 160 away from the base, and the second fixing portion is directly fixed to the mounting surface. It can be understood that when the first fixing portion and the second fixing portion meet their own rigidity requirements, the surfaces of the first fixing portion and the second fixing portion can also be wrapped with a flexible material to further achieve a shock-absorbing effect.

[0076] Please refer to Figures 7 to 10 In one embodiment of the present invention, the camera 200 comprises:

[0077] A cylindrical shell 210, one end of which is an open structure, and two opposite side surfaces of the cylindrical shell 210 are provided with a second connection structure;

[0078] A front end cover 220, the front end cover 220 is connected to the open end of the cylindrical shell 210, a viewing window 221 is provided at one end of the front end cover 220 away from the cylindrical shell 210, and a mounting groove 223 is formed at one end of the front end cover 220 facing the cylindrical shell 210;

[0079] A first bracket 230, wherein the first bracket 230 is fixed to the bottom wall of the mounting groove 223, and the first bracket 230 is further formed with a clamping hole 231;

[0080] A lens assembly 240, wherein the front end of the lens assembly 240 is inserted into the clamping hole 231, and the window of the lens assembly 240 is disposed toward the viewing window 221;

[0081] The second bracket 250 includes a fixing plate 251 and bending arms 253 connected to opposite sides of the fixing plate 251, the bending arms 253 are fixed to the surface of the front end cover 220 facing the cylindrical shell 210 by screws, and the end of the lens assembly 240 away from the window is fixed to the fixing plate 251 by screws.

[0082] In a technical solution of an embodiment of the present invention, the space enclosed by the cylindrical shell 210 and the front cover 220 is used to install core components of the camera 200, such as the lens assembly 240, the circuit board, and the motor.

[0083] The front end of the lens assembly 240 refers to the end close to the shooting window, and the rear end of the lens assembly 240 refers to the end away from the shooting window. Among them, the front and rear ends of the lens assembly 240 are fixed by the first bracket 230 and the second bracket 250. Compared with the existing solution, only one bracket is used to fix the rear end of the lens assembly 240, resulting in a cantilevered situation of the lens assembly 240. By respectively arranging the first bracket 230 and the second bracket 250 at the front and rear ends of the lens assembly 240, the first bracket 230 and the second bracket 250 can form force support points at the front and rear ends of the lens assembly 240, respectively, thereby improving the reliability of the connection between the lens assembly 240 and the front cover 220.

[0084] The first bracket 230 and the second bracket 250 are both fixed to the front cover 220 by screws. The first bracket 230 is a plastic part, which can reduce the weight of the front end of the camera 200. The end surface of the first bracket 230 is formed with a reinforcing rib 233 arranged around the outer periphery of the clamping hole 231 to effectively strengthen the structural strength of the first bracket 230. The second bracket 250 is a sheet metal part, which can ensure the structural strength of the second bracket 250 and facilitate the processing of the second bracket 250 into a complex structure adapted to the front cover 220. For example Fig.10 As shown, the bending arm 253 of the second bracket 250 is L-shaped, so that the plane of the locking screw on the bending arm 253 is parallel to the plane where the fixing plate 251 is located. This makes it easy for the second bracket 250 to be locked with the front end cover 220, while the fixing plate 251 also abuts against the rear end of the lens assembly 240 under the action of the locking force, thereby improving the reliability of the locking of the lens assembly 240 and the fixing plate 251.

[0085] Please refer to Figures 8 to 10In one embodiment of the present invention, the camera 200 further includes a shock-absorbing rubber ring 260, which includes: a main body 261 and a fixing part 263, and is in a cylindrical structure. The main body 261 is sandwiched between the inner wall surface of the clamping hole 231 and the outer wall surface of the lens assembly 240, and the inner wall surface of the main body 261 is also provided with a plurality of annular convex ribs 2611 at intervals along its axial direction; the fixing part 263 is connected to one end of the main body 261, and the fixing part 263 includes a plurality of fixing pieces 2631, each of which is extended in the axial direction of the main body 261, and a plurality of fixing pieces 2631 are arranged around the outer peripheral surface of the main body 261, and one of the fixing pieces 2631 is inserted between the two reinforcing ribs 233 on the end surface of the first bracket 230 to fix the shock-absorbing rubber ring 260.

[0086] In the technical solution of an embodiment of the present invention, the material of the shock-absorbing rubber ring 260 is a flexible material. The main body 261 of the shock-absorbing rubber ring 260 is assumed to be between the inner wall surface of the clamping hole 231 and the outer wall surface of the lens assembly 240, which can further improve the stability of the lens assembly 240 and reduce the vibration transmission between the lens assembly 240 and other components. At the same time, the inner wall surface of the main body 261 is also provided with a plurality of annular convex ribs 2611 along its axial direction, which are used to partially contact with the outer wall of the front end of the lens assembly 240 to avoid excessive friction resistance that makes the assembly of the lens assembly 240 difficult. At the same time, it can also provide flexible support for the front end of the lens assembly 240, while reducing the shaking of the lens assembly 240 and improving reliability, and further shock reduction. The plurality of fixing pieces 2631 on the fixing part 263 cooperate with the end face reinforcing ribs 233 of the first bracket 230, which can not only fix the shock-absorbing rubber ring 260, but also prevent the shock-absorbing rubber ring 260 from rotating along its axial direction, and realize the limit rotation.
