Description

Technical Field

[0001] 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

[0002] When using a streaming media rearview mirror, you need to stick a camera on the windshield to provide real-time images for the streaming media rearview mirror. The inclination angle of the rear windshield varies greatly for different cars. For example, the inclination angle of the rear windshield of a pickup truck is about 90 degrees, while the inclination angle of the rear windshield of some sports cars is about 20 degrees. This causes great trouble for streaming media rearview mirror manufacturers, because manufacturers do not know whether the end customer's car is a sports car or a pickup truck when shipping. The common practice is to equip each streaming media rearview mirror with several cameras to adapt to different models, but this increases the manufacturer's cost.

[0003] In order to adapt to two types of vehicles with different windshield inclination angles, a shell and a camera bracket can be set, and one end of the camera is fixed to the shell, so that the camera bracket can rotate 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 the 20-degree inclination glass. When the camera needs to adapt to a glass with a 90-degree inclination, the camera bracket can be rotated to an angle suitable for the 90-degree inclination glass. However, only one end of the existing camera is fixed to the shell. As the vehicle vibrates during driving, there is a problem of rotating around the fixed end and sagging, 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 sag. Utility Model Content

[0071] Please also refer to Figure 1 and Figure 4Since the camera 2 includes a first portion 20 and a second portion 21 on different sides, the first portion 20 is clamped in the first clamping hole 100 of the outer shell 10 and the second clamping 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 droop, and will not fall out of the outer shell 10. Specifically, Figure 4 As shown, since there are at least four fixing areas C1 to C4 between the camera 2 and the outer shell 10 and the inner shell 12, namely, the C1 area and the C2 area use the first clamping hole 100 and the second clamping hole 120 to fix the camera 2, and the C3 area and the C4 area use the fastener 13 to fix the camera 2, the camera 2 will not rotate relative to the C1 area and the C2 area.

[0072] Please also refer to Figure 1 and Figure 5 Optionally, the outer shell 10 includes a first card hole 100 to allow the camera 2 to be exposed, that is, the outer shell 10 allows the lens 22 (see the lens 22 for details) to be exposed. Figure 2 ) is exposed at the front. The first clamping hole 100 may be a circular hole, and the first clamping hole 100 may be arranged at the front side of the outer shell 10. The first clamping hole 100 may be arranged at the first front wall 102 of the outer shell 10. The first clamping hole 100 and the second clamping hole 120 may be coaxially arranged. The first part 20 clamped in the first clamping hole 100 may be an interference fit between the front circumference of the camera 2 and the first clamping hole 100. The outer shell 10 may include a screw column 104, and the inner shell 12 may be fixed to the screw column 104 of the outer shell 10 by a screw. For example, the rear part of the inner shell 12 may be fixed to the screw column 104 by a screw. The first part 20 is clamped in the first clamping hole 100, which can further fix the front part of the camera 2, and at the same time, the inner shell 12 can be fixed with the help of the camera 2 to prevent the inner shell 12 from moving in a direction parallel to the X-axis.

[0073] Please also refer to Figure 1 , Figure 2 and Figure 5 When installing the camera 2, first insert the camera 2 between the second clamping hole 120 and the first limit portion 121 of the inner shell 12, then insert the camera 2 and the inner shell 12 as a whole into the outer shell 10 from the opening above the outer shell 10 and fix the inner shell 12 to the screw column 104 of the outer shell 10. Finally, put the two arms 110 of the bracket 11 (see the arm 110 for details) Figure 6 ) are respectively clamped on the left inner wall and the right inner wall of the outer shell 10, and are aligned with the first clamping tooth portion 101 and the second clamping tooth portion 1100 (the second clamping tooth portion 1100 is shown in FIG. Figure 6 ) and the screw hole 210, and then the 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 to complete the fixing of the camera 2.

[0074] Please also refer to Figure 1 , Figure 5 and Figure 6 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, and the second latching tooth portion 1100 and the first latching tooth portion 101 are coaxially arranged and meshed with each other. The number of the first latching tooth portion 101 can be two and they 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 pivoting 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 of 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 used as the pivot is 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 .

[0075] Please also refer to Figure 1 , Figure 5 and Figure 6 Optionally, the first latching tooth portion 101 includes a plurality of first latching teeth 1010, and the plurality of first latching teeth 1010 can be evenly distributed with reference to the X-axis. The first latching tooth portion 101 is disposed on the inner side of the outer shell 10, and the second latching tooth portion 1100 is disposed on the outer side of the bracket 11, so that the left inner side and the right inner side of the bracket 11 can respectively abut against the second portion 21 on the left side and the second portion 21 on the right side. Since the second portion 21 is usually made of metal material (for example, the second portion 21 can be made of aluminum alloy or zinc alloy), and the bracket 11 is usually made of plastic, compared with the existing plastic bracket component and the plastic outer shell that can be rotatably connected, the friction coefficient of the bracket 11 relative to the second portion 21 in the former is larger, thereby making the friction between the bracket 11 and the second portion 21 larger.

[0076] Please also refer to Figure 5 and Figure 6 Optionally, the first latching tooth portion 101 includes a plurality of first latching teeth 1010, the second latching tooth portion 1100 includes a plurality of second latching teeth 11000, and the number of the first latching teeth 1010 is less than the number of the second latching teeth 11000. The plurality of second latching teeth 11000 can be evenly distributed with the X axis as a reference. The number of the first latching teeth 1010 is less than the number of the second latching teeth 11000 to ensure that the bracket 11 (please refer to the bracket 11 Figure 1 ) has multiple adjustable angles while reducing the jamming of the first latching tooth 1010 on the second latching tooth 11000 (because the second latching tooth 11000 will not be blocked or jammed when rotating between the two first latching teeth 1010).

[0077] Please also refer to Figure 1 , Figure 5 and Figure 6 , the adjustable angle of the bracket 11 can be determined by the angle between adjacent second latch teeth 11000 and the number of the rotated second latch teeth 11000. The number of the second latch teeth 1100 can be two and they are respectively arranged on the left outer wall and the right outer wall of the bracket 11. For example, the two second latch teeth 1100 can be respectively arranged on the outer side surface of the left support arm 110 and the outer side surface of the right support arm 110. The thickness of the second latch teeth 1100 is substantially the same as the distance between the end surface of the second portion 21 and the first latch teeth 101 to prevent the camera 2 from shaking. The thickness direction of the second latch teeth 1100 is parallel to the X-axis.

[0078] Please also refer to Figure 1 , Figure 5 and Figure 6 Optionally, the outer shell 10 includes an avoidance groove 1020, the bracket 11 includes a support arm 110, the second latching tooth portion 1100 is arranged on the support arm 110, and the avoidance groove 1020 is used to avoid the support arm 110. The avoidance groove 1020 can be arranged at the upper end of the first front wall 102. The number of the avoidance grooves 1020 can be two and they are arranged one by one with the support arm 110. The cross section of the avoidance groove 1020 can be rectangular. The two avoidance grooves 1020 can be arranged on the left and right sides of the first latch hole 100.

[0079] Please also refer to Figure 1 , Figure 5 and Figure 6 Optionally, the bracket 11 may include two arms 110, and a second tooth 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 be suitable for being installed on the windshield 3 of the car at 90 degrees, and the bottom of the avoidance groove 1020 may also stop the arm 110 to prevent the bracket 11 from being excessively turned. 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 direction of the X-axis.

The fastener 13 can be a screw. The number of the fastener 13, the screw hole 210, the first through hole 103, and the second through hole 1101 can be two each and be arranged one-to-one.

[0081] The two screw holes 210 can be respectively arranged on the left and right sides of the camera 2. The two first through holes 103 can be respectively arranged on the two sides of the outer shell 10. The end of the fastener 13 can be screwed with the screw hole 210, and the head of the fastener 13 can abut against the edge of the outer end of the first through hole 103. The edge of the first through hole 103 can be a portion of the outer shell 10 surrounding the outer end of the first through hole 103, and the diameter of the edge of the first through hole 103 and the diameter of the head of the fastener 13 can be substantially the same.

[0082] Please also refer to Figure 1 , Figure 5 and Figure 6 , each first through hole 103 can be coaxially arranged with the corresponding first latching tooth portion 101 in a one-to-one correspondence. Two second through holes 1101 can be respectively arranged at the ends of the two arms 110. Each second through hole 1101 can be coaxially arranged with the corresponding second latching tooth portion 1100 in a one-to-one correspondence. One end of the fastener 13 passes through the first through hole 103 and the second through hole 1101 and is screwed to 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 fix the bracket 11 and the camera 2 at the same time, and 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, respectively, thereby saving the number of fasteners 13 required.

[0083] Please also refer to Figure 1 , Figure 5 and Figure 6 , the number of fasteners 13 used is reduced, and the installation steps required when fastening the fasteners 13 can be saved. The screw hole 210 can be the original one of the camera 2. The second part 21 can be made of metal material (such as aluminum alloy or zinc alloy), so that the fastener 13 and the screw hole 210 of the second part 21 are more firmly screwed together.

The length direction of the first limiting portion 121 can be parallel to the second front wall 122. For example, the length direction of the first limiting portion 121 can be parallel to the X-axis direction. The first limiting portion 121 can be integrally formed with the inner shell 12. The first limiting portion 121 can prevent the camera 2 from moving in the negative direction parallel to the Y-axis. The edge of the second clamping hole 120 can be an area surrounding the second clamping hole 120 on the inner surface of the second front wall 122. The camera 2 can be clamped between the inner surface of the second front wall 122 and the front surface of the first limiting portion 121.

[0085] Please also refer to Figure 1 and Figure 7 Optionally, the inner shell 12 includes a second limiting portion 123, 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 may be two side plates of the inner shell 12, that is, the second limiting portion 123 may be parallel to the YOZ plane. The second limiting portion 123 may be integrally formed with the inner shell 12. The second limiting portion 123 may include a transition section 1230 that is adapted to the side edge of the second portion 21 so that the second limiting portion 123 may clamp the second portion 21 more accurately. The second limiting portion 123 may prevent the camera 2 from moving in the positive direction parallel to the Y axis.

[0086] Please also refer to Figure 1 and Figure 7 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 at the notch 124. The notch 124 can be provided on the side plate of the inner shell 12, and the second limiting portion 123 can be located at the left edge of the notch 124. For example, a notch 124 can be provided on the left plate and the right plate of the inner shell 12 respectively. The notch 124 on the side wall of the inner shell 12 can save the material required to form the inner shell 12. The direction of 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 plate on the inner shell 12. The second portion 21 is exposed at the notch 124, which can facilitate one end of the fastener 13 to reach the screw hole 210, that is, one end of the fastener 13 does not need to pass through the inner shell 12.

[0087] Please also refer to Figure 1 , Figure 2 and Figure 7Optionally, the number of the second limit portions 123 is two, and the distance between the two second limit portions 123 is substantially the same as the width of the camera body 23. The two second limit portions 123 may be arranged parallel to each other. The distance between the two second limit portions 123 may 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 may be parallel to the X-axis, that is, the width of the camera body 23 may be the distance between the left side and the right side of the camera body 23. The distance between the two second limit portions 123 and the width of the camera body 23 being substantially 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 a central axis parallel to the Y-axis.

[0088] Please also refer to Figure 1 and Figure 8 When the fixing structure 1 is used, the camera 2 can be first fixed to the fixing structure 1. When fixed to the windshield 3 of the pickup truck (the windshield 3 of the pickup truck has an inclination angle of about 90 degrees), the bracket 11 can be rotated to a suitable first angle, and then the bonding portion 111 can be attached to the windshield 3. Fig. 9 As shown, when fixed to the windshield 3 of a sports car (the windshield 3 of the sports car has an inclination angle of about 20 degrees), the bracket 11 can be rotated to a suitable second angle, and then the bonding portion 111 is bonded to the windshield 3. Since the bracket 11 can be rotated relative to the camera 2 and the outer shell 10, the fixing structure 1 can also be adapted to the windshield 3 of other models with an inclination angle between 20 degrees and 90 degrees.

[0089] Please also refer to Figure 1 , Figure 2 and Fig.10 The outer shell 10, the edge of the second clamping hole 120, the first limiting portion 121, the second limiting portion 123 and the inner shell 12 enclose a receiving space, and the camera 2 can be clamped in the receiving space to achieve accurate positioning and fixation of the camera 2, so that the camera 2 is not easy to escape from the receiving space whether it moves or rotates. Moreover, the camera 2 is used as an intermediate connecting member to connect the inner shell 12 and the outer shell 10, avoiding the need to set too many fastening components to connect the inner shell 12 and the outer shell 10, so that the efficiency of assembling the inner shell 12 and the outer shell 10 is higher.

[0090] like Fig.11 As shown, in another embodiment, a portion of the outer shell 10 can be removed to avoid collision between the outer shell 10 and the roof of the car. That is, in this embodiment, only the outer shell 10 is different from the previous embodiment, and the other parts are the same as the previous embodiment. For example, the outer shell 10 in this embodiment can be formed by removing the upper part of the rear end of the outer shell 10 in the previous embodiment, so that the upper top surface of the outer shell 10 after removal is roughly parallel to the XOY plane.

[0091] In another embodiment, a camera device is provided, comprising a camera 2 and the fixing structure 1 in the above embodiment, wherein the camera 2 is fixed to the fixing structure 1. The camera 2 can be arranged in the fixing structure 1, and the fixing structure 1 can be fixed to the windshield 3 of the car by bonding.

[0092] 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, according to the concept of the embodiments of the present application, there will be some changes in the specific implementation and application scope. In summary, the content of this specification should not be understood as a limitation on the present application. All equivalent modifications or changes made according to the spirit and technical ideas of the present application should still be covered by the claims of the present application.
