Description

Fixed structure and camera device

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on December 7, 2023, with application number: CN202311679787.4, and invention name: “Fixed structure and camera device”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the technical field of vehicle-mounted electronics, and in particular to a fixing structure and a camera device. Background Art

[0003] When using a streaming rearview mirror, a camera needs to be attached to the windshield to provide the real-time image. The tilt angle of the rear windshield varies significantly between different vehicles. For example, the tilt angle of the rear windshield of a pickup truck is approximately 90 degrees, while that of some sports cars is approximately 20 degrees. This creates significant supply difficulties for streaming rearview mirror manufacturers, as manufacturers do not know whether the end customer's vehicle is a sports car or a pickup truck at the time of shipment. A common practice is to equip each streaming rearview mirror with several cameras to accommodate different vehicle models, but this increases manufacturers' costs.

[0004] In order to adapt to two types of vehicles with different windshield inclination angles, a shell and a camera bracket can be provided, and one end of the camera can be fixed to the shell, so that the camera bracket can be rotated relative to the shell. When the camera needs to adapt to a windshield with a 20-degree inclination, the camera bracket can be rotated to an angle suitable for 20-degree inclination glass. When the camera needs to adapt to 90-degree inclination glass, the camera bracket can be rotated to an angle suitable for 90-degree inclination glass. However, the existing camera is only fixed to the shell at one end. As the vehicle vibrates during driving, there is a problem that the camera rotates around the fixed end and droops, and there is even a risk of detaching from the shell. Therefore, the existing camera fixing device has the problem that the camera is easy to rotate and droop.

[0035] For ease of explanation, a rectangular coordinate system O-XYZ is established in each figure. The X-axis is aligned with the width of the inner housing 12, the Y-axis is aligned with the length of the inner housing 12, and the Z-axis is aligned with the height of the inner housing 12. The X-axis can be coaxial with the screw hole 210 of the camera 2. The positive directions of the X-axis, Y-axis, and Z-axis remain the same in each figure with a coordinate system.

[0036] As shown in FIG1 , this embodiment provides a fixing structure 1 for fixing a camera 2. The camera 2 includes a first portion 20 and a second portion 21, which are located on different sides of the camera 2. The fixing structure 1 includes an outer shell 10, a bracket 11, and an inner shell 12. The outer shell 10 includes a first latching hole 100, into which the first portion 20 is latched. The bracket 11 is rotatably connected to the outer shell 10, and the second portion 21 is rotatably connected to the bracket 11, which is connected to the outer shell 10. The inner shell 12 includes a second latching hole 120, into which the first portion 20 is latched, and the inner shell 12 is connected to the outer shell 10.

[0037] Please refer to Figures 1 and 2 simultaneously. The bracket 11 includes a fitting portion 111 for fitting to the windshield 3 of the automobile (please refer to Figure 8 for the windshield). The right bottom end of the bracket 11 can be rotatably connected to the outer shell 10 and the second portion 21. The camera 2 can be roughly cube-shaped. The camera 2 can acquire images along a direction parallel to the Y-axis. The second portion 21 can be the middle and rear portion of the camera 2. The second portion 21 and the bracket 11 are rotatably connected, that is, the bracket 11 can rotate relative to the second portion 21. The camera 2 and the outer shell 10 are relatively stationary. The second portion 21 and the outer shell 10 can be screwed together by fasteners 13. The camera 2 can include a lens 22 and a camera body 23. The lens 22 is used to acquire images, and the camera body 23 is used to fix the lens 22 and the second portion 21. The cross-section of the lens 22 can be circular. The cross-section of the camera body 23 can be rectangular. The front portion of the lens 22 can be exposed on the front side of the camera body 23.

[0038] Please refer to Figures 1 and 2 simultaneously. Optionally, the front portion of the lens 22 can protrude in the direction of the front side of the camera body 23, that is, the front portion of the lens 22 can protrude from the front side of the camera body 23 in a direction parallel to the Y-axis. The first portion 20 can be the head of the camera 2. The first portion 20 can be located on the front side of the camera 2. The first portion 20 includes the front portion of the lens 22 and the front portion of the camera body 23. As shown in Figure 2, the plane passing through the bottom surface of the first portion 20 and parallel to the XOZ plane is plane A, and the portion of the camera 2 located to the left of plane A is the first portion 20. The first portion 20 can be locked in the second locking hole 120, and the front portion of the camera 2 can be exposed in the second locking hole 120, and the front portion of the camera body 23 can be pressed against the inner edge of the second locking hole 120. The second locking hole 120 can prevent the camera 2 from moving in the positive direction parallel to the Y-axis.

[0039] Referring to Figures 2 and 3 , the front side surface area of ​​the camera body 23 is larger than the cross-sectional area of ​​the second engagement hole 120. The cross-sectional area of ​​the front portion of the lens 22 is approximately the same as the diameters of the first and second engagement holes 100, 120. This allows the front portion of the lens 22 to protrude beyond the first and second engagement holes 100, 120, leaving the camera body 23 obstructed by the inner edge of the second engagement hole 120. The second portion 21 can protrude perpendicularly to the left or right side of the camera body 23, that is, the second portion 21 can protrude parallel to the X-axis from the left or right side of the camera body 23. There can be two second portions 21, one located on the left and one located on the right side of the camera body 2.

[0040] As shown in Figure 3, the planes passing through the bottom surfaces of the second parts 21 on the left and right sides and parallel to the YOZ plane are plane B1 and plane B2 respectively. Then, the part of the camera 2 protruding from the camera body 23 from plane B1 is the second part 21 on the left, and the part of the camera 2 protruding from the camera body 23 from plane B2 is the second part 21 on the right.

[0041] Referring to Figures 1 and 2 , the outer housing 10 can be a housing with an upper opening, and the inner housing 12 and camera 2 can be inserted into the outer housing 10 through the upper opening. The bracket 11 can be pivotally connected to the outer housing 10. The bracket 11 can be pivotally connected to the second portion 21. A portion of the bracket 11 can be sandwiched between the second portion 21 and the outer housing 10. The bracket 11 can rotate about the X-axis. The second engaging hole 120 can be located inside the first engaging hole 100.

[0042] Please refer to Figures 1 and 2 at the same time. The inner shell 12 as a whole can be L-shaped. The second card hole 120 can be a circular hole, and the second card hole 120 can be set at the front of the inner shell 12. The second card hole 120 can be set at the second front wall 122 of the inner shell 12 (please refer to Figure 7 for the second front wall 122). The central axis of the second card hole 120 can be parallel to the Y axis. The rear part of the inner shell 12 can be fixed to the outer shell 10 by screws. The inner shell 12 can be set inside the outer shell 10. The bracket 11, the inner shell 12 and the outer shell 10 can be made of plastic (for example, the bracket 11, the inner shell 12 and the outer shell 10 can be made of PC+ABS or PC).

[0043] Referring to Figures 1 and 4 simultaneously, since the camera 2 includes a first portion 20 and a second portion 21 on different sides, the first portion 20 is engaged with the first engagement hole 100 of the outer shell 10 and the second engagement hole 120 of the inner shell 12, and the second portion 21 is connected to the outer shell 10, the camera 2 will not rotate around the first portion 20 and sag, and thus will not fall out of the outer shell 10. Specifically, as shown in Figure 4, since the camera 2, the outer shell 10, and the inner shell 12 have at least four fixing areas C1 to C4, namely, areas C1 and C2 are used to fix the camera 2 using the first engagement hole 100 and the second engagement hole 120, and areas C3 and C4 are used to fix the camera 2 using the fastener 13, the camera 2 will not rotate relative to areas C1 and C2.

[0044] Please refer to Figures 1 and 5 at the same time. Optionally, the outer shell 10 includes a first card hole 100 to expose the camera 2, that is, the outer shell 10 can expose the front of the lens 22 (please refer to Figure 2 for the lens 22). The first card hole 100 can be a circular hole, and the first card hole 100 can be set on the front side of the outer shell 10. The first card hole 100 can be set on the first front wall 102 of the outer shell 10. The first card hole 100 and the second card hole 120 can be coaxially arranged. The first part 20 is clamped in the first card hole 100, which can be an interference fit between the front circumference of the camera 2 and the first card hole 100. The outer shell 10 may include a screw column 104, and the inner shell 12 can be fixed to the screw column 104 of the outer shell 10 by screws. For example, the rear part of the inner shell 12 can be fixed to the screw column 104 by screws. The first portion 20 is locked in the first locking hole 100 to further fix the front of the camera 2 and, at the same time, the inner housing 12 can be fixed by means of the camera 2 to prevent the inner housing 12 from moving in a direction parallel to the X-axis.

[0045] Referring to Figures 1, 2, and 5, when installing the camera 2, first insert the camera 2 between the second latching hole 120 and the first stopper 121 of the inner housing 12. Then, insert the camera 2 and inner housing 12 as a whole into the outer housing 10 through the top opening of the outer housing 10 and secure the inner housing 12 to the screw post 104 of the outer housing 10. Finally, the ends of the two arms 110 (see Figure 6 for arms 110) of the bracket 11 are respectively secured to the left and right inner walls of the outer housing 10, aligning the first latching tooth 101 and the second latching tooth 1100 (see Figure 6 for the second latching tooth 1100) with the screw hole 210. Finally, the ends of the fastener 13 are passed through the first through-hole 103 and the second through-hole 1101 and screwed into the screw hole 210 to secure the camera 2.

[0046] Please refer to Figures 1, 5, and 6 simultaneously. Optionally, the inner side of the outer shell 10 includes a first latching tooth portion 101, and the outer side of the bracket 11 includes a second latching tooth portion 1100. The second latching tooth portion 1100 and the first latching tooth portion 101 are coaxially arranged and mesh with each other. There can be two first latching tooth portions 101, which are respectively arranged in the middle of the left inner wall of the outer shell 10 and the middle of the right inner wall of the outer shell 10. The second latching tooth portion 1100 can be pivotally connected to the first latching tooth portion 101. For example, the pivot connecting the first latching tooth portion 101 and the second latching tooth portion 1100 can be a fastener 13. When the fastener 13 serves as the pivot between the first latching tooth portion 101 and the second latching tooth portion 1100, threads can be provided only at the end of the fastener 13, and the section of the fastener 13 serving as the pivot can be smooth. The fastener 13 serves as a pivot of the first latching tooth portion 101 and the second latching tooth portion 1100 , that is, the fastener 13 simultaneously connects the camera 2 , the bracket 11 and the outer shell 10 and provides a pivot for the bracket 11 .

[0047] Referring to Figures 1, 5, and 6, the first latching portion 101 optionally includes a plurality of first latching teeth 1010, which can be evenly distributed about the X-axis. The first latching portion 101 is disposed on the inner side of the outer shell 10, and the second latching portion 1100 is disposed on the outer side of the bracket 11. This allows the left and right inner sides of the bracket 11 to abut against the left and right second portions 21, respectively. Since the second portion 21 is typically made of metal (e.g., aluminum alloy or zinc alloy), and the bracket 11 is typically made of plastic, the friction coefficient of the bracket 11 relative to the second portion 21 is greater in the former than in conventional rotatable connections between a plastic bracket component and a plastic outer shell, thereby increasing the friction between the bracket 11 and the second portion 21.

[0048] Referring to Figures 5 and 6 , the first latching tooth portion 101 optionally includes a plurality of first latching teeth 1010, and the second latching tooth portion 1100 includes a plurality of second latching teeth 11000. The number of first latching teeth 1010 is less than the number of second latching teeth 11000. The plurality of second latching teeth 11000 can be evenly distributed about the X-axis. Having fewer first latching teeth 1010 than second latching teeth 11000 ensures that the bracket 11 (see Figure 1 for bracket 11) has multiple adjustable angles while minimizing the chance of the first latching teeth 1010 jamming against the second latching teeth 11000 (because the second latching teeth 11000 can rotate between the two first latching teeth 1010 without being blocked or jammed).

[0049] Please refer to Figures 1, 5, and 6 simultaneously. The adjustable angle of the bracket 11 can be determined by the angle between adjacent second latch teeth 11000 and the number of rotated second latch teeth 11000. The number of second latch teeth 1100 can be two, and they can be respectively provided on the left outer wall and the right outer wall of the bracket 11. For example, the two second latch teeth 1100 can be provided on the outer side surface of the left support arm 110 and the outer side surface of the right support arm 110, respectively. The thickness of the second latch tooth 1100 is approximately the same as the distance between the end surface of the second portion 21 and the first latch tooth 101 to prevent the camera 2 from shaking. The thickness direction of the second latch tooth 1100 is parallel to the X-axis.

[0050] Referring to Figures 1, 5, and 6 simultaneously, the outer shell 10 optionally includes an escape groove 1020, the bracket 11 includes a support arm 110, and the second latching tooth portion 1100 is disposed on the support arm 110. The escape groove 1020 is used to escape the support arm 110. The escape groove 1020 can be disposed at the upper end of the first front wall 102. There can be two escape grooves 1020, each corresponding to one of the support arms 110. The cross-section of the escape groove 1020 can be rectangular. The two escape grooves 1020 can be disposed on the left and right sides of the first latching hole 100.

[0051] Please refer to Figures 1, 5 and 6 at the same time. Optionally, the bracket 11 may include two arms 110, and a second latch portion 1100 is provided on the outer side surface of the end of each arm 110. The end of the arm 110 may be located inside the outer shell 10. The inner side surface of the end of the arm 110 may abut against the second portion 21. The avoidance groove 1020 may provide an avoidance space for the arm 110 to continue rotating when the bracket 11 needs to be rotated to a position suitable for installation on the windshield 3 of a car at 90 degrees. At the same time, the bottom of the avoidance groove 1020 may also stop the arm 110 to prevent the bracket 11 from being excessively rotated. The two arms 110 may rotate around the X-axis. The thickness of the arm 110 may be approximately equal to the width of the avoidance groove 1020. The thickness direction of the arm 110 is parallel to the X-axis.

[0052] Referring to Figures 1, 5, and 6 simultaneously, the fixing structure 1 optionally further includes a fastener 13, the second portion 21 includes a screw hole 210, the outer shell 10 includes a first through hole 103, and the bracket 11 includes a second through hole 1101. One end of the fastener 13 passes through the first through hole 103 and the second through hole 1101 and is screwed into the screw hole 210, while the other end of the fastener 13 abuts against the edge of the first through hole 103. The fastener 13 may be a screw. The number of fasteners 13, the screw hole 210, the first through hole 103, and the second through hole 1101 may each be two, and they may be arranged in a one-to-one correspondence.

[0053] Two screw holes 210 can be provided on the left and right sides of the camera 2, respectively. Two first through holes 103 can be provided on either side of the outer shell 10, respectively. The ends of the fasteners 13 can be screwed into the screw holes 210, and the heads of the fasteners 13 can abut against the outer edges of the first through holes 103. The edge of the first through hole 103 can be the portion of the outer shell 10 surrounding the outer ends of the first through hole 103. The diameter of the edge of the first through hole 103 and the diameter of the heads of the fasteners 13 can be substantially the same.

[0054] Please refer to Figures 1, 5 and 6 simultaneously. Each first through hole 103 can be coaxially arranged with the corresponding first latching tooth portion 101. The two second through holes 1101 can be respectively arranged at the ends of the two support arms 110. Each second through hole 1101 can be coaxially arranged with the corresponding second latching tooth portion 1100. One end of the fastener 13 passes through the first through hole 103 and the second through hole 1101 and is screwed into the screw hole 210. That is, the screw hole 210, the first through hole 103 and the second through hole 1101 can be coaxially arranged. That is, only one fastener 13 is needed on the left and right sides of the outer shell 10 to simultaneously fix the bracket 11 and the camera 2. There is no need to use screws to fix the bracket 11 and the outer shell 10 and to fix the outer shell 10 and the camera 2, thereby saving the number of fasteners 13 required.

[0055] Referring to Figures 1, 5, and 6, the number of fasteners 13 used is reduced, which can also save the installation steps required to tighten the fasteners 13. The screw holes 210 can be the original ones of the camera 2. The second part 21 can be made of a metal material (such as an aluminum alloy or a zinc alloy), which can provide a more secure screw connection between the fasteners 13 and the screw holes 210 of the second part 21.

[0056] Referring to Figures 1, 2, and 7 simultaneously, the inner housing 12 optionally includes a first limiting portion 121, spaced apart from the second engaging hole 120, with the camera 2 being retained between the edge of the second engaging hole 120 and the first limiting portion 121. The first limiting portion 121 can be in the shape of an elongated rectangular parallelepiped. The first limiting portion 121 can be disposed on the inner surface of the upper side wall of the inner housing 12. The length of the first limiting portion 121 can be parallel to the second front wall 122. For example, the length of the first limiting portion 121 can be parallel to the X-axis. The first limiting portion 121 can be integrally formed with the inner housing 12. The first limiting portion 121 can prevent the camera 2 from moving in a negative direction parallel to the Y-axis. The edge of the second engaging hole 120 can be the area surrounding the second engaging hole 120 on the inner surface of the second front wall 122. The camera 2 can be retained between the inner surface of the second front wall 122 and the front surface of the first limiting portion 121.

[0057] Please refer to Figures 1 and 7 at the same time. Optionally, the inner shell 12 includes a second limiting portion 123, and the second limiting portion 123 and the first limiting portion 121 are spaced apart, and the second portion 21 abuts against the second limiting portion 123. The second limiting portion 123 can be two side plates of the inner shell 12, that is, the second limiting portion 123 can be parallel to the YOZ plane. The second limiting portion 123 can be integrally formed with the inner shell 12. The second limiting portion 123 may include a transition section 1230 whose direction is adapted to the side edge of the second portion 21 so that the second limiting portion 123 can clamp the second portion 21 more accurately. The second limiting portion 123 can prevent the camera 2 from moving in the positive direction parallel to the Y axis.

[0058] Please refer to Figures 1 and 7 simultaneously. Optionally, the inner shell 12 includes a notch 124, the second limiting portion 123 is located at the edge of the notch 124, and the second portion 21 is exposed in the notch 124. The notch 124 can be provided on the side panel of the inner shell 12, and the second limiting portion 123 can be located at the left edge of the notch 124. For example, the left and right panels of the inner shell 12 can each be provided with a notch 124. The notch 124 in the sidewall of the inner shell 12 can save the material required to form the inner shell 12. The notch 124 can be roughly L-shaped, that is, the second limiting portion 123 can be formed by removing the L-shaped notch 124 from the rectangular side panel of the inner shell 12. The exposure of the second portion 21 in the notch 124 can facilitate the access of one end of the fastener 13 to the screw hole 210, that is, one end of the fastener 13 does not need to pass through the inner shell 12.

[0059] Please refer to Figures 1, 2 and 7 at the same time. Optionally, the number of the second limiting parts 123 is two, and the distance between the two second limiting parts 123 is approximately the same as the width of the camera body 23. The two second limiting parts 123 can be arranged parallel to each other. The distance between the two second limiting parts 123 can be equal to the distance between the inner surface of the left plate and the inner surface of the right plate of the inner shell 12. The width direction of the camera body 23 can be parallel to the X-axis, that is, the width of the camera body 23 can be the distance between the left side and the right side of the camera body 23. The distance between the two second limiting parts 123 and the width of the camera body 23 being approximately the same can prevent the camera 2 from moving left and right in a direction parallel to the X-axis and prevent the camera 2 from rotating around the central axis parallel to the Y-axis.

[0060] Please refer to Figures 1 and 8 simultaneously. When using the fixing structure 1, the camera 2 can be first fixed to the fixing structure 1. When fixed to the windshield 3 of a pickup truck (the windshield 3 of a pickup truck has an inclination angle of approximately 90 degrees), the bracket 11 can be rotated to a suitable first angle, and then the fitting portion 111 can be attached to the windshield 3. As shown in Figure 9, when fixed to the windshield 3 of a sports car (the windshield 3 of a sports car has an inclination angle of approximately 20 degrees), the bracket 11 can be rotated to a suitable second angle, and then the fitting portion 111 can be attached to the windshield 3. Since the bracket 11 can rotate relative to the camera 2 and the outer shell 10, the fixing structure 1 can also adapt to windshields 3 of other models with inclination angles between 20 degrees and 90 degrees.

[0061] Referring to Figures 1, 2, and 10 simultaneously, the outer housing 10, the edge of the second retaining hole 120, the first retaining portion 121, the second retaining portion 123, and the inner housing 12 form a receiving space. The camera 2 can be retained by the receiving space, achieving precise positioning and fixation of the camera 2, making it difficult for the camera 2 to escape from the receiving space regardless of movement or rotation. Furthermore, the camera 2 serves as an intermediate connector connecting the inner housing 12 and the outer housing 10, eliminating the need for excessive fastening components to connect the inner housing 12 and the outer housing 10, thereby increasing the efficiency of assembly of the inner housing 12 and the outer housing 10.

[0062] As shown in Figure 11, in another embodiment, a portion of the outer shell 10 can be removed to prevent collision between the outer shell 10 and the roof of the vehicle. That is, only the outer shell 10 in this embodiment differs from the previous embodiment; all other parts are the same. For example, the outer shell 10 in this embodiment can be formed by removing the upper rear end portion of the outer shell 10 in the previous embodiment, such that the upper surface of the outer shell 10 after removal is approximately parallel to the XOY plane.

[0063] In yet another embodiment, a camera device is provided, comprising a camera 2 and the fixing structure 1 of the aforementioned embodiment, wherein the camera 2 is fixed to the fixing structure 1. The camera 2 may be disposed within the fixing structure 1, and the fixing structure 1 may be fixed to the windshield 3 of the vehicle by bonding.

[0064] The above is a detailed introduction to the fixing structure and camera device provided in the embodiments of the present application. For those skilled in the art, the specific implementation and scope of application may vary based on the concepts of the embodiments of the present application. In summary, the contents of this specification should not be construed as limiting the present application. All equivalent modifications or changes made based on the spirit and technical concepts of the present application shall still be covered by the claims of the present application.
