Description

Technical Field

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

[0002] Fasteners are essential basic components in mechanical engineering and are widely used in all walks of life to connect and fix various structural parts. 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 automotive manufacturing industry in the prior art, fasteners are particularly widely used, especially on the assembly line of the main engine factory, where fasteners are used to fix various parts such as body structure, interior parts, electronic equipment, etc.

[0003] With the rapid development of intelligent driving technology, ADAS cameras have gradually become one of the standard configurations of modern cars. In order to ensure the installation quality and stability of the camera, OEMs usually use specially designed fasteners to fix the camera to the front windshield. Specifically, the camera is installed in a double-layer fixing method: first, the cover is fitted on the opening of the front windshield bracket; then, the ADAS camera is inserted into the side slot of the cover in an oblique manner; finally, the auxiliary bracket is covered and the auxiliary bracket is fixed to the snap-in point on the front windshield bracket. This design not only enhances the camera's anti-vibration performance, but also facilitates subsequent calibration and maintenance.

[0004] However, in actual operation, the operator needs to apply a certain amount of pressing force when fitting the cover to the front bracket and fixing the auxiliary bracket in place. However, the pressing force of different operators may vary, resulting in inconsistent tightness of the fitting points. If the pressing force is insufficient, the cover or auxiliary bracket may not be completely fixed, affecting the stability of the camera; and excessive pressing force may damage the camera or other components, resulting in such a double-sleeve straight-buckle pressing structure requiring special verification of the installation insertion force and extraction force of the components. After the structure undergoes long-term creep or stress relaxation, the buckle retention force will decrease, and the assembly fixing effect will loosen or fail. Summary of the invention

[0017] Compared with the prior art, the above technical solution provided by the present invention has at least the following beneficial effects: (1) By integrating the swivel arm module, negative pressure fastening mechanism and secondary fastening module, efficient self-locking and multi-level fixing functions are achieved, significantly improving the stability and reliability of the installation. Ensure that it can be accurately aligned with the reserved opening during the insertion process. Use the pre-pressing trigger inclined plate of the pressed L-shaped fastener to squeeze the fitting frame opening on the other side inward and firmly clamp the two side wing ears of the camera. This design not only simplifies the installation steps, but also completes the initial fixation in one-step pressing operation, greatly improving the installation efficiency. In addition, the elastic design of the pre-pressing trigger inclined plate enables it to generate sufficient rotational force when under pressure, ensuring that the swivel arm module applies uniform pressure to the ADAS camera, avoiding the problem of uneven tightness of the fitting points that may occur in traditional fixing methods.

[0018] (2) Through the negative pressure fastening mechanism and linkage mechanism. When the ADAS camera presses down on the pre-load trigger ramp, the linkage mechanism will start synchronously, pushing the piston sleeve to slide in the sealing tank, generating negative pressure. The negative pressure is transmitted to the rubber suction cup through the air duct, so that it firmly adsorbs the bottom of the pre-load trigger ramp, forming a second fixation. This process not only increases the fixing strength, but also ensures the close fit between the pre-load trigger ramp and the rubber suction cup through the cooperation of the magnetic suction plate. The design of the negative pressure fastening mechanism cleverly utilizes the downward force of the ADAS camera, and can achieve automatic negative pressure adsorption without an additional power source, simplifying the system structure and reducing maintenance costs. At the same time, the introduction of negative pressure adsorption effectively prevents loosening caused by vibration or external force, ensuring that the ADAS camera always maintains a stable installation state during use.

[0019] (3) It is 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 mobile frame to shrink toward the middle, so that the semicircular frames on both sides gradually approach and finally fit tightly to the camera end of the camera. The combined design of the spring telescopic rod and the third magnetic plate enables the semicircular frames to be quickly locked when approaching, forming a complete ring structure to wrap and fix the ADAS camera in all directions. This multi-level fixing mechanism not only improves the overall stability, but also effectively prevents the camera from loosening or falling off during long-term use. Through the integrated self-locking fastening structure, combined with negative pressure adsorption and secondary fastening, efficient, stable and reliable ADAS camera installation and fastening operations are achieved.

[0024] The following is a detailed description of a self-locking fixing structure for electronic components on a car windshield provided by the present invention in conjunction with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 10 As shown, the embodiment of the present invention provides a self-locking fixing structure of electronic components on a car windshield, comprising a bracket plate 1, wing plates 3 are fixedly connected at positions on both sides of the upper surface of the bracket plate 1, a rotating arm rotating shaft module 2 is fixedly installed at a position located in the middle of both sides of the bracket plate 1, and the rotating arm rotating shaft module 2 on each side is movably sleeved with a rotating arm module 6, and a first limit point 4 and a second limit point 5 arranged one above the other are fixedly installed at a position on one side end of the wing plates 3 on both sides of the bracket plate 1 away from the rotating arm rotating shaft module 2; A first reserved opening 7 for inserting a cover and a second reserved opening 8 for inserting an ADAS camera are provided at the middle position of the upper surface of the bracket plate 1, and a third limit point 9 is fixedly installed at the position of the middle end of the outer side of the second reserved opening 8 on the upper surface of the bracket plate 1, and an extended base plate 11 is fixedly connected to the side of the third limit point 9, and a negative pressure fastening mechanism 12 and a linkage mechanism 13 are arranged at positions near the rotating arm module 6 on both sides of the upper surface of the extended base plate 11; Among them, the swing arm module 6 includes an L-shaped fastener 61 and support arms 62 on both sides of the L-shaped fastener 61 for movably clamping in the swing arm rotating shaft module 2. The side of the L-shaped fastener 61 close to the bracket plate 1 is fixedly connected with a pre-pressure trigger inclined plate 63, and the other side is fixedly installed with a fitting frame opening 65. When the ADAS camera is inserted into one side of the second reserved opening 8, the bottom is pressed downward against one side of the pre-pressure trigger inclined plate 63 of the L-shaped fastener 61, and the fitting frame opening 65 on the other side is squeezed inward and sleeved on the two side wing ears of the ADAS camera, and as the pre-pressure trigger inclined plate 63 is further pressed downward, the linkage mechanism 13 is pushed down to make the negative pressure fastening mechanism 12 generate negative pressure to adsorb the bottom of the pre-pressure trigger inclined plate 63.

[0026] In order to solve the problem of uneven tightness of the fitting points during the double-layer fixed installation of the ADAS camera, the problem is solved by adopting the above-mentioned technical solution. The above-mentioned technical solution is mainly composed of a bracket plate 1, a swivel arm rotating shaft module 2, a wing plate 3, and a swivel arm module 6. The bracket plate 1 is a plate structure similar to the front windshield bracket a in the prior art, and a plurality of hollow frames for assembly are opened at the side angle positions on the surface. The wing plate 3 and the bracket plate 1 are an integral structure for configuring a first limit support point 4 and a second limit support point 5, and the first limit support point 4 and the second limit support point 5 are an inclined U-shaped sleeve structure as a whole for the side end of the ADAS camera to be inserted. The so-called ADAS camera, that is, the intelligent sensing system for assembly on the windshield in the prior art, is equipped with a corresponding acquisition camera for real-time capturing the situation inside and outside the car, and a corresponding locking pile is arranged on the outer surface. The first reserved opening 7 and the second reserved opening opened on the surface of the bracket plate 1 8 is a hollow opening structure, wherein 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, and the second reserved opening 8 on the outside is reserved for the camera end of the ADAS camera, and the swivel arm rotating shaft module 2 is composed of a round sleeve shaft 21 and a semi-open sleeve shaft 22 as a whole, wherein the round sleeve shaft 21 is a sleeve shaft structure with an insertion opening at the center of the circle, and the semi-open sleeve shaft 22 is a sleeve shaft structure with a semicircular opening, in order to facilitate the insertion of the support arm 62 of the swivel arm module 6. When inserting, the support arm 62 on one side is first inserted into the round mouth of the round sleeve shaft 21 at an inclined angle, and then the support arm 62 on the other side is pressed into the side opening of the semi-open sleeve shaft 22, so that one side of the opening of the semi-open sleeve shaft 22 is facing the middle side of the bracket plate 1, which is convenient for the rotation of the L-shaped fastener 61, and the so-called L-shaped fastener 61 is an L-shaped fastener structure as a whole; Among them, the swivel arm rotating axis module 2 plays the role of providing a rotating axis, with the round mouth of the round mouth sleeve shaft 21 as the origin, so that the angle between the pre-stressing point and the locking point is less than 90 degrees, that is, the inner angle between one side of the pre-stressing trigger inclined plate 63 and the fitting frame mouth 65 is less than 90 degrees. After the ADAS camera is pre-installed, the camera is pressed down until one end of the locking point fitting frame mouth 65 is fitted. Since one side of the pre-stressing trigger inclined plate 63 is elastic and has a large elasticity, the pre-stressing point is subjected to pressure when the ADAS camera is pressed down, and the swivel arm locking point with the rotating axis as the origin applies pressure constraints on the ADAS in the Y-axis and Z-axis directions. At this time, the swivel arm locking point and the pre-stressing point cooperate with the first limit support point 4 and the second limit support point 5 of the front block bracket to perform front and rear clamping and fixing, and combined with the third limit support point 9, the swivel arm and the front block bracket are constrained in six degrees of freedom in space, and the ADAS or the electronic components in front of the phase are completely fixed, so that one-step pressing can achieve firm self-locking and fixing.

[0027] like Figures 6 to 10As shown, the negative pressure fastening mechanism 12 includes a sealing tank 121, the top of which is fixedly connected to a ball-mouth sealing sleeve 122, and a cavity ball buckle 123 is movably sleeved in the ball-mouth sealing sleeve 122, and one end of the cavity ball buckle 123 which is sleeved into the ball-mouth sealing sleeve 122 is fixedly connected to an air guide tube 126 which is communicated with the interior of the cavity ball, a third reserved opening 127 is opened at the center position of the upper surface of the sealing tank 121, and one end of the air guide tube 126 away from the cavity ball buckle 123 extends into the interior of the sealing tank 121 through the third reserved opening 127.

[0028] Among them, the configured sealing tank 121 and the ball-mouth sealing sleeve 122 are an integrated structure, wherein the ball-mouth sealing sleeve 122 is a hemispherical sleeve structure as a whole, and a cavity ball buckle 123 is movably sleeved inside the hemispherical sleeve, and a sealing ring is provided on the inner wall of the hemispherical sleeve to ensure the sealing of the sleeve end, and the outer surface of the cavity ball buckle 123 is also provided with a sealing sleeve, on the one hand to ensure the sealing of the sleeve end, on the other hand to ensure that when the cavity ball buckle 123 rotates inside the ball-mouth sealing sleeve 122, sufficient damping is provided so that it can stop when it rotates to a certain angle, and the interior of the cavity ball buckle 123 is set as a cavity structure, so as to communicate with the connected air guide tube 126 so that the two structures can communicate with each other.

[0029] like Figures 1 to 10 As shown, a rubber suction cup 124 is fixedly installed on one end of the cavity ball buckle 123 that is exposed from the ball mouth sealing sleeve 122, and a suction port that communicates with the cavity inside the cavity ball buckle 123 is opened at the center position of the circle of the rubber suction cup 124, and a first magnetic attraction plate 125 is fixedly installed on the outer circular edge of the rubber suction cup 124, and a magnetic attraction coating that is attracted to the first magnetic attraction plate 125 is configured on the side where the bottom of the pre-pressure trigger inclined plate 63 is in contact with the rubber suction cup 124, and a piston sleeve 128 is slidably installed inside the sealing tank 121, and a pull rod 129 is fixedly connected to the bottom axial position of the piston sleeve 128, and the pull rod 129 passes through the bottom of the sealing tank 121.

[0030] Among them, the configured rubber suction cup 124 is fixedly connected to one end of the cavity ball buckle 123 that exposes the ball mouth sealing sleeve 122, and a suction port that communicates with the cavity inside the cavity ball buckle 123 is opened at the center position of the circle of the rubber suction cup 124. When the piston sleeve 128 is pulled downward along with the pulling rod 129, the structure of the needle tube syringe in the prior art can be simulated, and negative pressure will be generated during the pulling process. The cavity ball buckle 123 located on the upper side of the sealing tank 121 is connected with its interior through the air guide tube 126, so the generated negative pressure area can be transmitted to the inner side of the rubber suction cup 124, and the pressing end is adsorbed by the rubber suction cup 124. In order to ensure the sealing of the piston sleeve 128 during the pulling process, the outer surface of the piston sleeve 128 is configured with a sealing ring.

[0031] like Figures 6 to 10 As shown, the linkage mechanism 13 includes a linkage push rod 131 which is movably inserted and installed on the side of the sealed can 121, a torsion spring rod 132 is movably installed on the top of the linkage push rod 131, and a circular ring plate 133 is fixedly installed on the torsion end of the torsion spring rod 132, the inner opening of the circular ring plate 133 is larger than the can body of the sealed can 121, and the upper surface of the circular ring plate 133 is provided with a second magnetic attraction plate 134 corresponding to the bottom adsorption of the pre-pressure trigger inclined plate 63, the bottom of the linkage push rod 131 is fixed with a horizontal plate 135, and the side surfaces of the horizontal plate 135 are fixedly connected to the bottom of the pull rod 129 on the same side.

[0032] Among them, the torsion spring rod 132 configured at the top of the linkage push rod 131 is to make the circular ring sleeve 133 connected to the outside have a certain reset toughness. On the one hand, it is used to ensure that when one end of the circular ring sleeve 133 is attached to the extrusion end, that is, when the pre-pressure triggering inclined plate 63 of the swing arm modules 6 on both sides is pressed, it can be tightly attached to the bottom of the pre-pressure triggering inclined plate 63. Therefore, the torsion angle of the torsion spring rod 132 is within the range lifted outward from one side of the linkage push rod 131, and the lifting angle is less than 90 degrees. In this state, the annular sleeve 133 is tilted toward one end of the linkage push rod 131 as a whole, and in order to prevent the annular sleeve 133 from over-turning by more than 90 degrees under the torsional force of the torsion spring rod 132, a limiting mechanism is further arranged on the side angle of the linkage push rod 131 to prevent the annular sleeve 133 from turning outward by more than 90 degrees. In order to further ensure the tightness of the fit between the annular sleeve 133 and the bottom of the pre-pressure trigger inclined plate 63, a second magnetic suction plate 134 is arranged so as to be adsorbed on the bottom of the pre-pressure trigger inclined plate 63.

[0033] like Figures 6 to 10 As shown, the swing arm rotating axis module 2 includes a round sleeve shaft 21 and a semi-open sleeve shaft 22, and the round sleeve shaft 21 and the semi-open sleeve shaft 22 are fixedly connected to the side of the bracket plate 1 in pairs, and a swing arm limiting inclined plate 10 is fixedly installed at the position between the round sleeve shaft 21 and the semi-open sleeve shaft 22, and a plurality of reinforcing rib plates 64 are fixedly installed at the position where the pre-pressure trigger inclined plate 63 and the sleeve frame mouth 65 intersect.

[0034] The configured reinforcing rib plate 64 is used to strengthen the strength of the angle on the one hand, and on the other hand, the raised bumps can be used to isolate the bonding end, thereby increasing the heat dissipation performance of the bonding end. In order to improve the shock absorption performance of the bonding end, the reinforcing rib plate 64 can be selected not only as a common plastic structure, but also as a rubber cotton structure; The specific working principle of the configured linkage mechanism 13 and the cooperation arm module 6 of the negative pressure fastening mechanism 12 is as follows: First, the ADAS camera is obliquely inserted into the inner side of the wing plate 3, slides between the first limit point 4 and the second limit point 5, and then presses downward on the pre-pressure triggering inclined plate 63 of the L-shaped fastener 61, so that when the pre-pressure triggering inclined plate 63 is squeezed and rotated, it will synchronously contact one end of the annular sleeve 133 downward, and under the adsorption effect of the second magnetic plate 134 of the annular sleeve 133, the pre-pressure triggering inclined plates 63 on both sides are adsorbed; Then, as the pre-pressure triggering inclined plate 63 further rotates and presses down, the linkage push rods 131 on both sides extend downward under the action of the squeezing force, so that the horizontal plate 135 at the bottom of the linkage push rod 131 pulls the pull rod 129 in the sealing tank 121 to be pressed down synchronously, and cooperates with the piston sleeve 128 inside the sealing tank 121 to generate negative pressure; Finally, as the pre-stress triggering inclined plate 63 is further pressed downward, the annular sleeve 133 is lower than the sealing can 121, and the pre-stress triggering inclined plate 63 will contact the rubber suction cup 124 on the cavity ball buckle 123, and finally, as the L-shaped fastener 61 is completely fastened on both sides of the ADAS camera, the pressed pre-stress triggering inclined plate 63 will also be firmly adsorbed by the rubber suction cup 124, forming a second fixation; Furthermore, because the pre-stress triggering inclined plate 63 is pressed downward in a rotational manner, one end of the cavity ball buckle 123 is in a movable spherical shape so as to move along with the movement of the pre-stress triggering inclined plate 63 .

[0035] like Figures 6 to 10 As shown, a secondary camera fastening module 14 is also installed at the bottom of the extended base plate 11, and the secondary camera fastening module 14 includes a square frame 141 fixedly installed at the two side ends of the bottom of the extended base plate 11, and the square frame 141 is provided with a slot flush with the extended base plate 11, and a movable frame 142 is sleeved in the slot, and the two side ends of the movable frame 142 are movably installed with a wheel 143 that fits with the slot in the square frame 141.

[0036] The configured moving frame 142 and the sleeve wheels 143 on both sides are integrally sleeved inside the square frame 141 . The sleeve wheels 143 are provided to make the moving frame 142 smoother during movement.

[0037] like Figures 6 to 10 As shown, a pulling rope 144 is fixedly connected to one side of the movable frame 142 facing the bottom axis of the extended base plate 11, and the pulling rope 144 passes through the side of the square frame 141 away from the movable frame 142, and the passing end is fixedly connected to the bottom of the horizontal plate 135 on the same side, and a bent extension rod 145 is fixedly connected to the bottom of the horizontal plate 135.

[0038] like Figures 6 to 10As shown, the bent extension rod 145 as a whole extends 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 a semicircular frame 146 is fixedly installed on the extended end, and the inner diameter length of the semicircular frame 146 is the same as the outer diameter length of the camera end of the ADAS camera.

[0039] 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 opening 8, so as to extend the semicircular frame 146 at the extended end to the positions on both sides of the camera end of the ADAS camera.

[0040] like Figures 6 to 10 As shown, a sponge cushion layer 147 is fixedly installed on the inner ring edge of the semicircular frame 146, and expansion plates 148 are fixedly connected at both side ends of the semicircular frame 146, and a spring telescopic rod 149 is slidably sleeved on each expansion plate 148.

[0041] like Figures 6 to 10 As shown, the spring return end of the spring telescopic rod 149 extends toward the midpoint of the extended base plate 11, and a third magnetic plate 1410 is fixedly installed on the extended end, and the magnetic poles of the third magnetic plate 1410 located on both sides of the bottom of the extended base plate 11 attract each other.

[0042] The spring telescopic rod 149 is a support rod structure with a reset spring coil in the prior art, and the reset spring coil on the spring telescopic rod 149 is used to make one end of the third magnetic attraction plate 1410 have a force to extend toward the midpoint of the extended base plate 11; The secondary fastening principle of the camera secondary fastening module 14 is: During the process of the ADAS camera being installed, the pre-pressure of the rotating arm module 6 is triggered by pressing down the inclined plate 63 to press down the linkage mechanism 13, so that the sleeve frame opening 65 is fastened to the outside of the ADAS camera. The linkage mechanism 13 not only unilaterally drives the negative pressure fastening mechanism 12 to generate negative pressure, but also pulls the camera secondary fastening module 14 to perform secondary fastening on the ADAS camera on one side of the second reserved opening 8. Furthermore, the pre-pressure triggering inclined plate 63 presses down the linkage push rod 131, and in the process of the linkage push rod 131 moving downward, the moving frame 142 in the square frame 141 on both sides will be pulled toward the middle side by the pulling rope 144 to cooperate with the set wheel 143, and in the process of moving the moving frame 142 on both sides toward the middle, the semicircular holding frame 146 on both sides will be moved closer and move toward one end of the ADAS camera, and because the expansion plates 148 on both sides of the semicircular holding frame 146 are provided with spring telescopic rods 149 extending outward, when the semicircular holding frames 146 on both sides are close, the third magnetic suction plates 1410 on both sides will be close first, and in a close state, the semicircular holding frames 146 on both sides will be tightly attached together by the adsorption force of the third magnetic suction plates 1410, so as to perform secondary fastening on one end of the ADAS camera; The negative pressure fastening mechanism 12 and the camera secondary fastening module 14 do not need to be fixed with an additional driving force. When the ADAS camera 3 cooperates with the arm rotating shaft module 2 to press down and the arm module 6 is used to press, multi-level fixing can be completed in one step.
