Description

Technical Field

[0001] The present invention relates to the technical field of device fasteners, and more specifically, to a self-locking fixing structure for electronic components on an automotive windshield. Background Art

[0002] Fasteners are essential basic components in mechanical engineering and are widely used in various industries for connecting and fixing various structural components. In modern industry, fasteners not only need to have high strength and durability but also must adapt to different materials, environments, and application requirements. For example, in the existing automotive manufacturing technology, fasteners are particularly widely used, especially on the assembly lines of vehicle manufacturers, where fasteners are used to fix various components such as body structures, interior parts, and electronic devices.

[0003] With the rapid development of intelligent driving technology, ADAS cameras have gradually become one of the standard configurations of modern vehicles. To ensure the installation quality and stability of the cameras, vehicle manufacturers usually use specially designed fasteners to fix the cameras on the front windshield. Specifically, the cameras are installed using a double-layer fixing method: First, the cover is sleeved over the opening of the front windshield bracket; then, the ADAS camera is inserted into the side slot of the cover in an oblique insertion manner; finally, the auxiliary bracket is covered, and the camera is fixed by docking the engaging points on the auxiliary bracket and the front windshield bracket. This design not only enhances the anti-vibration performance of the camera but also facilitates subsequent calibration and maintenance.

[0004] However, during actual operation, when sleeving the cover onto the front windshield bracket and fixing the auxiliary bracket in place, the operator needs to apply a certain pressing force. However, the pressing forces applied by different operators may vary, resulting in inconsistent tightness at the sleeving points. If the pressing force is insufficient, the cover or the auxiliary bracket may not be fully fixed, affecting the stability of the camera; while if the pressing force is too large, it may damage the camera or other components, resulting in the need for special verification of the insertion force and extraction force of such a double-sleeve straight-button pressing structure for component installation. Moreover, after the structure undergoes long-term creep or stress relaxation, the snap-holding force will decrease, and the assembly fixing effect will become loose or ineffective. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a self-locking fixing structure for electronic components on an automotive windshield, aiming to solve the above technical problems.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

[0007] A self-locking fixing structure for electronic components on an automotive windshield, including a support plate. At the positions of both sides of the upper surface of the support plate, wing plates are fixedly connected. At the positions in the middle of both sides of the support plate, swivel arm rotation shaft modules are fixedly installed, and a swivel arm module is movably sleeved on each side of the swivel arm rotation shaft module. At the positions of the ends of the wing plates on both sides of the support plate, away from the swivel arm rotation shaft module, a first limit stop point and a second limit stop point arranged one above the other are fixedly installed.

[0008] At the middle position of the upper surface of the support plate, a first reserved opening for inserting a lid and a second reserved opening for inserting an ADAS camera are provided. At the middle position of the outer side of the second reserved opening on the upper surface of the support plate, a third limit stop point is fixedly installed. The third limit stop point has a side fixedly connected with an extended base plate. At the positions of both sides of the upper surface of the extended base plate, close to the swivel arm module, a negative pressure fastening mechanism and a linkage mechanism are configured.

[0009] Among them, the swivel arm module includes an L-shaped fastener and arms on both sides of the L-shaped fastener for movably clamping in the swivel arm rotation shaft module. On the side edge of the L-shaped fastener close to the support plate, a pre-pressure trigger inclined plate is fixedly connected. On the other side, a fitting frame opening is fixedly installed. When the bottom of the ADAS camera inserted into the second reserved opening presses against one side of the pre-pressure trigger inclined plate of the L-shaped fastener, the fitting frame opening on the other side is inwardly extruded and sleeved on the two side wing ears of the ADAS camera. And as the pre-pressure trigger inclined plate is further pressed down, it will push down the linkage mechanism to make the negative pressure fastening mechanism generate negative pressure to adsorb the bottom of the pre-pressure trigger inclined plate.

[0010] As a further scheme of the present invention: The negative pressure fastening mechanism includes a sealed tank. At the top of the sealed tank, a spherical port sealing socket is fixedly connected, and a cavity ball buckle is movably sleeved in the spherical port sealing socket. One end of the cavity ball buckle sleeved into the spherical port sealing socket is fixedly connected with an air duct communicating with the inside of the cavity ball. At the center position of the upper surface of the sealed tank, a third reserved opening is provided, and the end of the air duct away from the cavity ball buckle extends into the inside of the sealed tank through the third reserved opening.

[0011] As a further scheme of the present invention: On the end of the cavity ball buckle exposed from the spherical port sealing socket, a rubber suction cup is fixedly installed. At the center position of the rubber suction cup, an adsorption port communicating with the inner cavity of the cavity ball buckle is provided. On the outer circular ring edge of the rubber suction cup, a first magnetic attraction plate is fixedly installed. On the side of the bottom of the pre-pressure trigger inclined plate that fits with the rubber suction cup, a magnetic attraction coating for adsorbing with the first magnetic attraction plate is configured. A piston sleeve disc is slidably installed inside the sealed tank. At the center position of the bottom of the piston sleeve disc, a pull rod is fixedly connected, and the pull rod passes through the bottom of the sealed tank.

[0012] As a further solution of the present invention: The linkage mechanism includes a linkage ejector rod movably inserted and installed on the side of the sealed tank. A torsion spring rod is movably installed on the top of the linkage ejector rod, and ring sleeve plates are fixedly installed on the torsion ends of the torsion spring rods. The inner opening of the ring of the ring sleeve plate is larger than the body of the sealed tank, and a second magnetic attraction plate corresponding to the adsorption of the bottom of the pre-pressure trigger inclined plate is arranged on the upper surface of the ring sleeve plate. Cross plates are fixed to the bottoms of the linkage ejector rods, and the sides of the cross plates are fixedly connected to the bottoms of the draw rods on the same side.

[0013] As a further solution of the present invention: The swivel arm rotation shaft module includes a round opening sleeve shaft and a semi-opening sleeve shaft. The round opening sleeve shaft and the semi-opening sleeve shaft are fixedly connected to the side of the support plate in pairs, and swivel arm limiting inclined plates are fixedly installed at positions between the round opening sleeve shaft and the semi-opening sleeve shaft. A number of reinforcing rib plates are fixedly installed at the position where the pre-pressure trigger inclined plate intersects with the nested frame opening.

[0014] As a further solution of the present invention: A camera secondary fastening module is further installed at the bottom of the extended base plate. The camera secondary fastening module includes square frames fixedly installed at both side ends of the bottom of the extended base plate. Slots flush with the extended base plate are opened in the frames of the square frames, and movable frames are sleeved in the slots. Sleeve wheels that fit with the slots in the square frames are movably installed at both side ends of the movable frames.

[0015] As a further solution of the present invention: Pulling ropes are fixedly connected to the sides of the movable frames facing the center of the bottom of the extended base plate. The sides of the pulling ropes away from the movable frames pass through the sides of the square frames, and the passing ends are fixedly connected to the bottoms of the cross plates on the same side. Bending extension rods are fixedly connected to the bottoms of the cross plates.

[0016] As a further solution of the present invention: The bending extension rods extend from one end of the bottom of the extended base plate to one side of the bottom of the second reserved opening, and semi-circular holding frames are fixedly installed at the extending ends. The inner diameter length of the semi-circular holding frames is the same as the outer diameter length of the imaging end of the ADAS camera.

[0017] As a further solution of the present invention: Sponge cushions are fixedly installed on the inner ring edges of the semi-circular holding frames, extension plates are fixedly connected to both side ends of the semi-circular holding frames, and spring telescopic rods are slidably sleeved on each extension plate.

[0018] As a further solution of the present invention: The spring reset ends of the spring telescopic rods extend towards the center point side of the extended base plate, and third magnetic attraction plates are fixedly installed at the extending ends. The third magnetic attraction plates on both sides of the bottom of the extended base plate attract each other with opposite magnetic poles.

[0019] The above technical solutions provided by the present invention have at least the following beneficial effects compared with the prior art:

[0020] (1) By integrating the swivel arm module, the negative pressure fastening mechanism, and the secondary fastening module, efficient self-locking and multi-stage fixing functions are achieved, significantly enhancing the stability and reliability of installation. Ensure that it can accurately align with the reserved opening during insertion. By pressing the pre-pressure trigger ramp of the L-shaped fastener, the fitting frame opening on the other side is squeezed inward to firmly clamp the two side wings of the camera. This design not only simplifies the installation steps but also completes the initial fixation in a single pressing operation, greatly improving the installation efficiency. In addition, the elastic design of the pre-pressure trigger ramp enables it to generate sufficient rotational force when pressed, ensuring that the swivel arm module applies uniform pressure to the ADAS camera and avoiding the problem of uneven tightness at the fitting points that may occur in traditional fixing methods.

[0021] (2) Through the negative pressure fastening mechanism and the linkage mechanism. When the ADAS camera presses down on the pre-pressure trigger ramp, the linkage mechanism is synchronously activated, pushing the piston sleeve disc to slide within the sealed tank to generate negative pressure. The negative pressure is transmitted through the air duct to the rubber suction cup, causing it to firmly adsorb the bottom of the pre-pressure trigger ramp, forming a second fixation. This process not only increases the fixing force but also ensures the tight fit between the pre-pressure trigger ramp and the rubber suction cup through the cooperation of the magnetic attraction plate. The design of the negative pressure fastening mechanism cleverly utilizes the downward pressure of the ADAS camera to achieve automatic negative pressure adsorption without an additional power source, simplifying the system structure and reducing the maintenance cost. At the same time, the introduction of negative pressure adsorption effectively prevents loosening caused by vibration or external forces, ensuring that the ADAS camera always maintains a stable installation state during use.

[0022] (3) Connected to the linkage mechanism through a pulling rope, during the process of inserting and pressing down the ADAS camera, the linkage mechanism will pull the moving frame to contract towards the middle, causing the two semi-circular holding frames on both sides to gradually approach and finally tightly fit around the imaging end of the camera. The combined design of the spring telescopic rod and the third magnetic attraction plate enables the semi-circular holding frames to quickly lock when approaching, forming a complete ring structure to wrap and fix the ADAS camera in all directions. This multi-stage fixing mechanism not only improves the overall stability but also effectively prevents the camera from loosening or falling off during long-term use. Through an integrated self-locking fastening structure, combined with negative pressure adsorption and secondary fastening, efficient, stable, and reliable installation and fastening operations for the ADAS camera are achieved.

[0044] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure. However, this is only for illustrative purposes and is not intended to limit the present invention to this specific structure, device and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs Detailed implementation manners

[0045] The following describes in detail a self-locking fixing structure for electronic components on an automotive windshield provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. Those skilled in the art in some well-known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention

[0046] As Figures 1 to 10 shown, an embodiment of the present invention provides a self-locking fixing structure for electronic components on an automotive windshield, including a support plate 1. Wing plates 3 are fixedly connected to both sides of the upper surface of the support plate 1. Rotary arm rotation shaft modules 2 are fixedly installed at the positions in the middle of both sides of the support plate 1, and a rotary arm module 6 is movably sleeved on each rotary arm rotation shaft module 2 on each side. First limit points 4 and second limit points 5 arranged one above the other are fixedly installed at the ends of the wing plates 3 on both sides of the support plate 1 away from the rotary arm rotation shaft modules 2

[0047] A first reserved opening 7 for inserting a lid and a second reserved opening 8 for inserting an ADAS camera are formed in the middle position of the upper surface of the support plate 1. A third limit point 9 is fixedly installed at the middle end outside the second reserved opening 8 on the upper surface of the support plate 1. A negative pressure fastening mechanism 12 and a linkage mechanism 13 are arranged at the positions close to the rotary arm module 6 on both sides of the upper surface of the extended base plate 11

[0048] Among them, the swing arm module 6 includes an L-shaped fastener 61 and two arms 62 on both sides of the L-shaped fastener 61 for movably clamping in the swing arm rotation shaft module 2. A pre-pressure trigger inclined plate 63 is fixedly connected to the side of the L-shaped fastener 61 close to the support plate 1, and a fitting frame opening 65 is fixedly installed on the other side. When the ADAS camera is inserted into one side of the second reserved opening 8, the bottom presses against one side of the pre-pressure trigger inclined plate 63 of the L-shaped fastener 61, squeezing the fitting frame opening 65 on the other side inward and sleeving it on both side wings of the ADAS camera. Moreover, as the pre-pressure trigger inclined plate 63 is further pressed down, it will push down the linkage mechanism 13 to cause the negative pressure fastening mechanism 12 to generate negative pressure to adsorb the bottom of the pre-pressure trigger inclined plate 63.

[0049] To solve the problem of uneven tightness of the fitting points during the double-layer fixed installation of the ADAS camera, the above technical solution is now adopted to solve it. The above technical solution mainly consists of a support plate 1, a swing arm rotation shaft module 2, a wing plate 3, and a swing arm module 6. The support plate 1 is a plate structure similar to the front windshield support a in the prior art, and a plurality of hollow frames for assembly are provided at the side angle positions on the surface. The wing plate 3 and the support plate 1 are of an integral structure and are used to configure the first limit contact point 4 and the second limit contact point 5. The first limit contact point 4 and the second limit contact point 5 are both inclined U-shaped socket structures for the side end of the ADAS camera to be inserted. The so-called ADAS camera is an intelligent sensing system used to be assembled on the front windshield in the prior art, equipped with a corresponding acquisition camera for real-time capturing of the situation inside and outside the vehicle, and corresponding engaging posts are provided on the outer surface. The first reserved opening 7 and the second reserved opening 8 provided on the surface of the support plate 1 are hollow opening structures. The first reserved opening 7 is used to engage the cover b in the prior art. After the cover b is engaged, it can provide a lifting force for the subsequent insertion of the ADAS camera. The second reserved opening 8 on the outside is reserved for the camera end of the ADAS camera. The swing arm rotation shaft module 2 is composed of a round socket shaft 21 and a semi-open socket shaft 22. The round socket shaft 21 is a socket shaft structure with an insertion opening at the center of the circle, and the semi-open socket shaft 22 is a socket shaft structure with a semi-circular opening, which is to facilitate the insertion of the arm 62 of the swing arm module 6. When inserting, first insert one side of the arm 62 into the round opening of the round socket shaft 21 at an inclined angle, and then press the other side of the arm 62 into the side opening of the semi-open socket shaft 22. Therefore, the opening sides of the semi-open socket shaft 22 all face the middle side of the support plate 1 to facilitate the rotation of the L-shaped fastener 61. The so-called L-shaped fastener 61 is an L-shaped fastener structure as a whole;

[0050] Among them, the swivel arm rotation axis module 2 serves to provide a rotation axis. Taking the circular opening of the circular opening sleeve shaft 21 as the origin, the angle between the preloading point and the locking point is less than 90 degrees, that is, the inner included angle between one side of the preloading trigger slant plate 63 and the inner included angle side of the fitting frame opening 65 is less than 90 degrees. After the ADAS camera is pre-installed, the camera is pressed down until one end of the fitting frame opening 65 of the locking point is sleeved. Since one side of the preloading trigger slant plate 63 has elasticity and a large amount of elasticity, when the ADAS camera is pressed down, the preloading point is subjected to pressure and the swivel arm locking point applies pressure constraints in the Y-axis direction and the Z-axis direction to the ADAS with the rotation axis as the origin. At this time, the swivel arm locking point and the preloading point cooperate with the first limit contact point 4 and the second limit contact point 5 of the front windshield bracket to perform front and rear snap-fitting fixation, and in combination with the third limit contact point 9, the swivel arm and the front windshield bracket are constrained in all six degrees of freedom in space, and the ADAS or the front electronic components are completely fixed, realizing firm self-locking fixation with one-step pressing.

[0051] As Figures 6 to 10 shown, the negative pressure fastening mechanism 12 includes a sealed tank 121. A spherical port sealing sleeve head 122 is fixedly connected to the top of the sealed tank 121, and a cavity spherical buckle 123 is movably sleeved in the spherical port sealing sleeve head 122. One end of the cavity spherical buckle 123 sleeved into the spherical port sealing sleeve head 122 is fixedly connected to an air duct 126 communicated with the inside of the cavity sphere. A third reserved port 127 is opened at the center position of the upper surface of the sealed tank 121, and one end of the air duct 126 away from the cavity spherical buckle 123 extends into the sealed tank 121 through the third reserved port 127.

[0052] Among them, the configured sealed tank 121 and the spherical port sealing sleeve head 122 are of an integral structure. The spherical port sealing sleeve head 122 is a hemispherical sleeve structure as a whole. A cavity spherical buckle 123 is movably sleeved inside the hemispherical sleeve opening. A sealing ring is arranged on the inner wall of the hemispherical sleeve opening to ensure the sealing performance of the fitting end. A sealing sleeve is also configured on the outer surface of the cavity spherical buckle 123. On the one hand, it is used to ensure the sealing performance of the fitting end, and on the other hand, it is used to ensure that when the cavity spherical buckle 123 rotates inside the spherical port sealing sleeve head 122, sufficient damping is provided so that it can stop when rotating to a certain angle. The inside of the cavity spherical buckle 123 is arranged as a cavity structure to communicate with the connected air duct 126 so that the two structures can communicate with each other.

[0053] As Figures 1 to 10As shown, a rubber suction cup 124 is fixedly installed at one end of the cavity ball buckle 123 exposed from the ball mouth sealing sleeve head 122. An adsorption port communicating with the inner cavity of the cavity ball buckle 123 is opened at the center position of the rubber suction cup 124. A first magnetic attraction plate 125 is fixedly installed on the outer circular ring edge of the rubber suction cup 124. A magnetic attraction coating for adsorbing the first magnetic attraction plate 125 is arranged on the side of the bottom of the pre-pressure trigger inclined plate 63 that fits the rubber suction cup 124. A piston sleeve disc 128 is slidably installed inside the sealed can 121. A draw rod 129 is fixedly connected to the center position of the bottom of the piston sleeve disc 128, and the draw rod 129 passes through the bottom of the sealed can 121.

[0054] Among them, the configured rubber suction cup 124 is fixedly connected to one end of the cavity ball buckle 123 exposed from the ball mouth sealing sleeve head 122. An adsorption port communicating with the inner cavity of the cavity ball buckle 123 is opened at the center position of the rubber suction cup 124. During the process of the piston sleeve disc 128 being pulled downward along with the draw rod 129, the structure of a syringe in the prior art can be simulated. A negative pressure will be generated during the pulling process. The cavity ball buckle 123 located above the sealed can 121 communicates with its interior through a gas guide pipe 126. Therefore, the generated negative pressure area can be transmitted to the inner side of the rubber suction cup 124, and the pressing end can be adsorbed by the rubber suction cup 124. In order to ensure the sealing performance of the piston sleeve disc 128 during the pulling process, a sealing ring is arranged on the outer surface of the piston sleeve disc 128.

[0055] As Figures 6 to 10 As shown, the linkage mechanism 13 includes a linkage ejector rod 131 movably inserted and installed on the side of the sealed can 121. A torsion spring rod 132 is movably installed at the top of the linkage ejector rod 131. Ring-shaped sleeve plates 133 are fixedly installed at the torsion ends of the torsion spring rods 132. The inner opening of the ring of the ring-shaped sleeve plate 133 is larger than the body of the sealed can 121. A second magnetic attraction plate 134 corresponding to the adsorption at the bottom of the pre-pressure trigger inclined plate 63 is arranged on the upper surface of the ring-shaped sleeve plate 133. Cross plates 135 are fixedly installed at the bottoms of the linkage ejector rods 131, and the sides of the cross plates 135 are fixedly connected to the bottoms of the draw rods 129 on the same side.

[0056] Among them, the torsion spring rod 132 configured at the top of the linkage ejector rod 131 is to endow the outer-connected ring sleeve plate 133 with a certain resilience for reset. On the one hand, it is used to ensure that when one end of the ring sleeve plate 133 fits against the extrusion end, that is, the pre-pressure trigger ramp 63 of the two-side swing arm module 6, it can closely fit against the bottom of the pre-pressure trigger ramp 63. Therefore, the torsion angle of the torsion spring rod 132 is within the range of lifting outwards from one side of the linkage ejector rod 131, and the lifting angle is less than 90 degrees. In the state without external extrusion, the entire ring sleeve plate 133 is inclined towards one end of the linkage ejector rod 131. And to prevent the ring sleeve plate 133 from flipping over excessively by more than 90 degrees under the action of the torsion force of the torsion spring rod 132, a limiting mechanism is configured at the side corner of the linkage ejector rod 131 to prevent the ring sleeve plate 133 from turning outwards by more than 90 degrees. And to further ensure the tightness of the fit between the ring sleeve plate 133 and the bottom of the pre-pressure trigger ramp 63, the second magnetic attraction plate 134 is arranged to adsorb on the bottom of the pre-pressure trigger ramp 63.

[0057] As Figures 6 to 10 shown, the swing arm rotation shaft module 2 includes a round mouth sleeve shaft 21 and a semi-open mouth sleeve shaft 22. The round mouth sleeve shaft 21 and the semi-open mouth sleeve shaft 22 are fixedly connected to the side of the support plate 1 in pairs, and swing arm limiting ramps 10 are fixedly installed at positions between the round mouth sleeve shaft 21 and the semi-open mouth sleeve shaft 22. A number of reinforcing rib plates 64 are fixedly installed at the position where the pre-pressure trigger ramp 63 and the fitting frame opening 65 are joined.

[0058] Among them, the configured reinforcing rib plates 64 are used on the one hand to strengthen the strength of the included angle, and on the other hand, the raised bumps can isolate the fitting end to increase the heat dissipation performance of the fitting end. And to improve the shock absorption performance of the fitting end, the reinforcing rib plates 64 can be selected not only as ordinary plastic structures but also as rubber cotton structures;

[0059] The specific working principle of the linkage mechanism 13 and the negative pressure fastening mechanism 12 in cooperation with the swing arm module 6 is as follows:

[0060] First, when the ADAS camera is obliquely inserted into the inner side of the wing plate 3 and slides between the first limit contact point 4 and the second limit contact point 5, and then pressed down on the pre-pressure trigger ramp 63 of the L-shaped fastener 61, when the pre-pressure trigger ramp 63 is squeezed and rotated, it will simultaneously contact one end of the ring sleeve plate 133 downward, and under the adsorption action of the second magnetic attraction plate 134 of the ring sleeve plate 133, it will adsorb the pre-pressure trigger ramps 63 on both sides;

[0061] Then, as the pre-pressure trigger ramp 63 further rotates and presses down, the linkage ejector rods 131 on both sides extend downward under the action of the extrusion force, causing the cross plate 135 at the bottom of the linkage ejector rod 131 to pull the draw rod 129 in the sealed tank 121 to press down synchronously, cooperating with the piston sleeve plate 128 inside the sealed tank 121 to generate negative pressure;

[0062] Finally, as the pre-pressure trigger ramp 63 further presses down, the circular ring sleeve plate 133 is lower than the sealed tank 121. At this time, the pre-pressure trigger ramp 63 will contact the rubber suction cup 124 on the cavity ball buckle 123, and finally, when the L-shaped fastener 61 is fully fastened on both sides of the ADAS camera, the pressing pre-pressure trigger ramp 63 will also be firmly adsorbed by the rubber suction cup 124 to form a secondary fixation;

[0063] Moreover, further, because during the downward pressing of the pre-pressure trigger ramp 63, it is a rotary downward pressing, so one end of the cavity ball buckle 123 is a movable spherical shape to facilitate moving along with the movement of the pre-pressure trigger ramp 63.

[0064] As Figures 6 to 10 shown, a camera secondary fastening module 14 is further installed at the bottom of the extended base plate 11. The camera secondary fastening module 14 includes a square frame 141 fixedly installed at both side ends of the bottom of the extended base plate 11. Slots flush with the extended base plate 11 are formed inside the square frame 141, and movable frames 142 are sleeved in the slots. And pulley wheels 143 that fit with the slots inside the square frame 141 are movably installed at both side ends of the movable frame 142.

[0065] Among them, the configured movable frame 142 and the pulley wheels 143 on both sides are integrally sleeved inside the square frame 141. The pulley wheels 143 are provided to make the movable frame 142 move more smoothly during the movement.

[0066] As Figures 6 to 10 shown, pulling ropes 144 are fixedly connected to the sides of the movable frame 142 facing the bottom center of the extended base plate 11. And the sides of the pulling ropes 144 away from the movable frame 142 pass through the sides of the square frame 141, and the passing ends are fixedly connected to the bottoms of the cross plates 135 on the same side. Bending and extending rods 145 are fixedly connected to the bottoms of the cross plates 135.

[0067] As Figures 6 to 10 shown, the bending and extending rods 145 extend from one end of the bottom of the extended base plate 11 to one side of the bottom of the second reserved opening 8, and semi-circular holding frames 146 are fixedly installed at the extending ends. The inner diameter length of the semi-circular holding frame 146 is the same as the outer diameter length of the imaging end of the ADAS camera.

[0068] Among them, the configured bent extension rod 145 is a bent rod, and the overall bending angle is bent from one end of the bottom of the extended base plate 11 to one side of the bottom of the second reserved port 8, so that the semi-circular holding frame 146 at the protruding end extends to both sides of the imaging end of the ADAS camera.

[0069] As Figures 6 to 10 shown, sponge cushions 147 are fixedly installed on the inner circular edges of the semi-circular holding frames 146, and extension plates 148 are fixedly connected to both side ends of the semi-circular holding frames 146, and telescopic spring rods 149 are slidably sleeved on each extension plate 148.

[0070] As Figures 6 to 10 shown, the spring return ends of the telescopic spring rods 149 extend towards the midpoint side of the extended base plate 11, and third magnetic attraction plates 1410 are fixedly installed on the protruding ends, and the third magnetic attraction plates 1410 at both sides of the bottom of the extended base plate 11 attract each other magnetically.

[0071] Among them, the configured telescopic spring rod 149 is a support rod structure with a return spring coil in the prior art, and the return spring coil on the telescopic spring rod 149 is used to make one end of the third magnetic attraction plate 1410 have a force to extend towards the midpoint of the extended base plate 11;

[0072] The secondary fastening principle of the camera secondary fastening module 14 is as follows:

[0073] During the installation process of the ADAS camera, when the pre-pressure trigger ramp 63 of the swivel arm module 6 is pressed down to drive the linkage mechanism 13, and the nested frame opening 65 is buckled on the outside of the ADAS camera, the linkage mechanism 13 not only drives the negative pressure fastening mechanism 12 to generate negative pressure unidirectionally, but also can pull the camera secondary fastening module 14 to perform secondary fastening on the ADAS camera on one side of the second reserved port 8;

[0074] Furthermore, when the pre-pressure trigger ramp 63 presses down the linkage ejector rod 131, during the downward movement of the linkage ejector rod 131, the moving frames 142 in the two side square frames 141 will be pulled towards the middle side by the pulling ropes 144 in cooperation with the sleeve wheels 143. When the two side moving frames 142 move towards the middle, the two semi-circular holding frames 146 will approach and move towards one end of the ADAS camera. And since the telescopic spring rods 149 extending outwards are arranged on the extension plates 148 on both sides of the semi-circular holding frames 146, when the two semi-circular holding frames 146 approach, the third magnetic attraction plates 1410 on both sides will approach first. In the approaching state, the two semi-circular holding frames 146 will be tightly attached together under the adsorption force of the third magnetic attraction plates 1410 to perform secondary fastening on one end of the ADAS camera;

[0075] Neither the described negative pressure fastening mechanism 12 nor the camera secondary fastening module 14 requires additional driving force for fixation. When the ADAS camera 3 cooperates with the rotating arm rotating shaft module 2 to press down and the rotating arm module 6 is used for pressing, multi-stage fixation can be completed in one step.
