Description

TECHNICAL FIELD

[0001] The application relates to the technical field of vehicle-mounted lenses, and particularly relates to a vehicle-mounted camera module fixing device. BACKGROUND

[0002] Most rearview mirrors of low-configured vehicles do not have a streaming media function, and currently, a streaming media rearview mirror is convenient to use, so many vehicles will choose to increase the streaming media rearview mirror.

[0003] The streaming media rearview mirror is divided into a replacement type and a covering fixed type. The replacement type needs to open a support box, remove an existing rearview mirror support, and then install a brand-new streaming media rearview mirror support and a rearview mirror. A front camera of the streaming media rearview mirror is installed at the front of the vehicle head or the front of the streaming media rearview mirror, and a rear camera of the streaming media rearview mirror is installed at the tail of the vehicle. The lines of the streaming media rearview mirror are hidden in the support, and after the support box is opened, the data lines are inserted into the support box to enter the vehicle body to connect the two cameras. The design has the advantages that the space in the vehicle is more tidy, and the disadvantages that each streaming media rearview mirror corresponds to the model of the vehicle.

[0004] The covering fixed type is fixed by buckling the streaming media rearview mirror with the existing rearview mirror. The method has the advantages that it is suitable for many vehicle models, and the disadvantages are as follows: I: If the front camera is synchronously set with the streaming media rearview mirror, the rearview mirror needs to be adjusted to the angle at which the driver can conveniently and clearly observe due to different heights and postures of the driver. After the angle of the rearview mirror is adjusted, the collection angle of the front camera also changes synchronously.

[0005] II: The camera cannot be set at the center of the streaming media rearview mirror because the rear of the covering fixed type streaming media rearview mirror is the original rearview mirror. The front camera cannot be collected if it is set at the top of the center line of the covering fixed type streaming media rearview mirror due to the obstruction of the support box. The front camera can only be installed at the bottom of the center line of the covering fixed type streaming media rearview mirror. If the front camera is installed at the bottom of the center line of the covering fixed type streaming media rearview mirror, the protrusion below the covering fixed type streaming media rearview mirror reduces the observation area of the glass.

[0006] III: On the basis of problems II and I, the driver observes the rear passengers and the rear glass outside during driving, and the observed rear image is not comprehensive due to the angle problem of the streaming media rearview mirror. The streaming media is used to increase the convenience of observation, and therefore, it is particularly important to increase the rear observation image after the streaming media rearview mirror. In order to overcome the problem, an in-vehicle rear camera needs to be additionally arranged. At this time, the in-vehicle rear camera and the in-vehicle front camera conflict with each other in position. If the in-vehicle rear camera and the in-vehicle front camera are not located at the center line, the images collected by the in-vehicle rear camera and the in-vehicle front camera will have a visual dead angle.

[0007] IV: The front camera in the car is fixed by the way of suction cup adhesion, which can make the front camera fixed on the glass, avoiding the interference between the rear camera and the front camera. However, the long time suction of the windshield glass can cause trace, film discoloration and film discoloration problems, which will also affect the observation. SUMMARY

DETAILED DESCRIPTION

[0022] Please refer to Figures 1-6 : In order to solve the interference problem between indoor front and rear cameras and fixed stream media rearview mirror, the front and rear cameras are fixed in the triangular area formed by the bracket box 100 and the fixed mirror rod 200 in the original rearview mirror in the following structure.

[0023] The reasons for selecting the triangular area as the fixing area are as follows: Please refer to Figure 3The bracket box 100 is fixedly connected to the mirror rod 200, and the mirror rod 200 is rotatably connected to the rearview mirror via a universal joint. A triangular area is formed between the bracket box 100 and the mirror rod 200. The triangular area is a light-proof area, so fixing in the triangular area will not affect the observation of the windshield. Secondly, the area outside the triangular area is the glass and ceiling cloth area, and it is difficult to set up a fixing device in such areas. The glass has been explained in the background technology, and the ceiling cloth can only be fixed by bonding. After the bonding fixation is removed, the ceiling cloth will be damaged and stained. The triangular area is basically made of plastic material, so the triangular area has little impact as a fixing area.

[0024] In order to fix the front and rear cameras in the triangle area, the following improvements are made: In this embodiment: the camera assembly 300 includes an upper buckle frame 1 and a lower buckle frame 2 that are interlocked and surround the mirror rod 200. The upper buckle frame 1 and the lower buckle frame 2 are slidably connected by two top pull pins 3 and two push-pull pins 4. The top of the upper buckle frame 1 is rotatably connected to the corner rod 5, and one end of the corner of the corner rod 5 provides pulling force by rotating the top pull pin 3. The bottom surface of the corner rod 5 is rotatably connected to the inclined sliding rod 7, and the end of the inclined sliding rod 7 is movably connected to the inclined insertion block 71. The inclined insertion block 71 slides on the surface of the upper buckle frame 1, and the inclined insertion block 71 provides pulling force to the push-pull pin 4 by sliding. The surface of the corner rod 5 is vertically fixedly connected to the telescopic support rod 6, and the telescopic end of the telescopic support rod 6 is rotatably connected to the contact plate 61 that contacts the bracket box 100.

[0025] Improvement principle: Please refer to Figure 5 The upper buckle frame 1 and the lower buckle frame 2 are designed to be split up and down. The upper buckle frame 1 and the lower buckle frame 2 are buckled together to clamp the mirror rod 200. If you want the upper buckle frame 1 and the lower buckle frame 2 to clamp the mirror rod 200 stably, the upper buckle frame 1 and the lower buckle frame 2 must always be subjected to the radial force of the mirror rod 200.

[0026] In order to apply radial force to the upper buckle frame 1 and the lower buckle frame 2, the following methods are used: The top of the upper buckle frame 1 is rotatably connected to the corner rod 5. The corner rod 5 has a corner, and the corner of the corner rod 5 is rotatably connected to the upper buckle frame 1. A telescopic support rod 6 is vertically arranged above the corner rod 5. The contact plate 61 contacts the bracket box 100. After the telescopic support rod 6 is extended, the telescopic support rod 6 generates downward pressure on the corner rod 5. One end of the corner rod 5 rotates upward to press against the top pull pin 3, and the top pull pin 3 is fixed to the lower buckle frame 2. The top pull pin 3 pulls upward at the upper buckle frame 1, and the corner rod 5 generates an upward pulling force on the top pull pin 3. The lower buckle frame 2 and the upper buckle frame 1 always move toward the mirror rod 200, and the lower buckle frame 2 and the upper buckle frame 1 generate a clamping force at one end.

[0027] See also Figures 5-6When the corner rod 5 descends, the corner rod 5 and the inclined sliding rod 7 increase the angle, the inclined plug 71 at the end of the inclined sliding rod 7 slides on the top surface of the upper buckle 1, the inclined plug 71 pushes the push-pull pin 4 to ascend, when the push-pull pin 4 ascends, the lower buckle 2 is stretched to move upward, and the lower buckle 2 and the upper buckle 1 at the other end generate clamping force.

[0028] Improvement advantage: The technical scheme utilizes the counter thrust of the support box 100 to convert into the clamping force of the upper buckle 1 and the lower buckle 2 on the mirror rod 200 to realize fixing. The whole fixing mode does not rely on destructive procedures such as bonding and screwing, and utilizes the triangular area feature of the automobile to realize fixing. The clamping area of the upper buckle 1 and the lower buckle 2 on the mirror rod 200 and the contact area of the top pull pin 3 on the support box 100 can be contacted through a buffer structure to realize nondestructive connection.

[0029] In order to reduce the damage caused by fixing the mirror rod 200, the following improvements are made: In the embodiment, the top surface of the lower buckle 2 is fixedly connected with a lower buckle plate 21, the bottom surface of the upper buckle 1 is fixedly connected with an upper buckle plate 11, and the upper buckle plate 11 and the lower buckle plate 21 are both provided with a hook plate for buckling the recessed part of the mirror rod 200.

[0030] Please refer to Figure 5 Many vehicles have recessed areas at the mirror rod 200, so the lower buckle plate 21 and the upper buckle plate 11 are buckled with the recessed areas of the mirror rod 200, the lower buckle 2 and the upper buckle 1 exert a small amount of friction force on the mirror rod 200, and the lower buckle plate 21 and the upper buckle plate 11 limit the recessed areas to realize fixing, which is more stable.

[0031] Supplementary explanation: If the vehicle does not have the recessed area in Figure 5 The hook plates of the upper buckle plate 11 and the lower buckle plate 21 are reversely arranged. The connection part of the rearview mirror and the mirror rod 200 must have a ball head. The ball head provides a rotation center for the universal rotation structure of the rearview mirror, the diameter of the mirror rod 200 must be smaller than that of the ball head, and the universal rotation structure cannot completely cover the ball head. Therefore, the upper buckle plate 11 and the lower buckle plate 21 can be arranged at the connection part of the ball head and the mirror rod 200 for limiting.

[0032] Improvement advantage: The clamping damage to the mirror rod 200 is reduced, and the structure limiting mode is more stable.

[0033] In the embodiment, the top pull pin 3 and the push-pull pin 4 are both slidably connected with the upper buckle 1, the bottom end of the top pull pin 3 and the bottom end of the push-pull pin 4 are both fixedly connected with the lower buckle 2, the top end of the top pull pin 3 is a planar boss, and the top end of the push-pull pin 4 is an inclined boss.

[0034] In the embodiment, please refer to Figure 6When the corner bar 5 rotates, the short side of the corner bar 5 is in sliding contact with the top pull pin 3, and thus the top end of the top pull pin 3 is a planar boss. The inclined block 71 slides on the top surface of the upper buckle 1, and the top end of the push-pull pin 4 is a beveled boss. The beveled surface of the inclined block 71 is in sliding cooperation with the beveled boss, and the inclined block 71 upwardly lifts the push-pull pin 4.

[0035] Supplementary explanation: The short side of the corner of the upper buckle 1 and the beveled surface of the inclined block 71 are both provided with a groove for accommodating the sliding of the top pull pin 3 and the push-pull pin 4.

[0036] The inclined block 71 and the upper buckle 1 can be connected through a sliding rail and a sliding block to realize directional sliding of the inclined block 71. Or the inclined block 71 is provided with a groove with an open top and bottom, and the rod part of the push-pull pin 4 is located inside the groove of the inclined block 71, so that the rod part of the push-pull pin 4 is surrounded by the groove and cannot be separated.

[0037] The adjustment mode of the collection position of the front lens 302 is as follows: In this embodiment, the lower lens bar 8 is rotationally connected to the end of the lower buckle 2 away from the support box 100, and the front lens 302 is rotationally connected to the end of the lower lens bar 8. The bottom surface of the lower buckle 2 has a groove for accommodating the lower lens bar 8 and the front lens 302.

[0038] The rotation angles of the lower lens bar 8 and the lower buckle 2 and the lower lens bar 8 and the front lens 302 can be fixed by locking. The locking modes include but are not limited to clamping friction force locking, hole-pin cooperation locking, gear-tooth block cooperation locking, etc. The lower lens bar 8 is rotated downward to adjust the position of the front lens 302, and the front lens 302 is angle-adjusted again with the lower lens bar 8. The top surface of the front lens 302 is flush with the bottom surface of the rearview mirror, which does not affect the observation area of the glass, and the image collected by the front lens 302 is collinear with the vertical center line of the vehicle.

[0039] The bottom surface of the lower buckle 2 has a groove for accommodating the lower lens bar 8 and the front lens 302. On the one hand, this can make the front lens 302 have a small accommodation volume. On the other hand, if the vertical extension distance of the bottom edge of the support box 100 is short, the front lens 302 can intrude into the groove, so that the front lens 302 is close to the bottom edge of the support box 100, and the bottom edge of the support box 100 does not affect the collection of the front lens 302.

[0040] The adjustment mode of the collection position of the rear lens 301 is as follows: The corner bar 5 is rotationally connected to the end away from the top pull pin 3, the upper lens bar 9 is rotationally connected to the end of the upper lens bar 9, and the upper buckle 1 is provided with a groove for accommodating the rear lens 301.

[0041] After the corner rod 5, the inclined slide rod 7 and the upper buckle frame 1 form a triangular support, the upper lens rod 9 is rotationally connected with the corner rod 5, the upper lens rod 9 is rotationally connected with the rear lens 301, and the upper lens rod 9 adjusts the rear lens 301 to be in the triangular area and above the rearview mirror. The rear lens 301 collects the image behind the driving position and transmits the information to the streaming media rearview mirror for the driver to observe. The rotation angle of the upper lens rod 9 and the upper buckle frame 1 and the rotation angle of the upper lens rod 9 and the rear lens 301 can be fixed by locking. The locking mode includes but is not limited to clamping friction force locking, hole pin cooperation locking, gear and block cooperation locking and the like.

[0042] Supplementary explanation: The number of corner rods 5 is two, and the rear lens 301 is located between the two corner rods 5. The advantage of two corner rods 5 is that the area between the two corner rods 5 can accommodate the rear lens 301, so that the rear lens 301 can invade the area to obtain a larger range of activity. Secondly, the rear lens 301 located in the triangular area will not affect the observation area of the glass.

[0043] The telescopic part of the telescopic support rod 6 is provided with a locking structure, and the telescopic support rod 6 can realize telescopic by adopting the form of screw rod pushing matched with self-locking structure. The screw rod pushing makes the telescopic distance of the telescopic support rod 6 more linear.

[0044] The contact surface of the contact plate 61 and the support box 100, the contact surface of the upper buckle plate 11 and the mirror rod 200, and the contact surface of the lower buckle plate 21 and the mirror rod 200 are all provided with a contact layer. The contact layer can be silicone, rubber, sponge and the like, which reduces the influence of clamping on the plastic parts.

[0045] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
