Description

Technical Field

[0001] The invention relates to the technical field of rearview mirror assembly, in particular to an automobile rearview mirror assembly device and method. Background Art

[0002] The existing automobile rearview mirror can not only be retracted and extended, but also the lens of the rearview mirror can be adjusted. A driving assembly is installed in the rearview mirror housing. Generally, the lens is clamped with the tray on the driving assembly through a clamp ring (composed of a plurality of clamp joints arranged in a ring shape) on the back. The driving assembly adjusts the deflection of the tray to adjust the angle of the lens in a small range of pitch angle, which makes up for the lack of angle adjustment of the rearview mirror housing, so that the field of view of the rearview mirror lens can be adjusted more flexibly. In the existing assembly device, when assembling the lens, the lens and the chuck are mostly directly pressed and clamped. However, since the driving assembly will be powered on and tested in the pre-process to check whether the adjustment tray can run smoothly, the adjustment tray is partially not reset after the test, so that the adjustment tray is in a tilted state after the driving assembly is installed on the housing. At this time, when the mirror surface is directly clamped with the adjustment tray in one posture, since a large pressure needs to be applied to the lens, the contact between the lens and the two sides of the adjustment tray is uneven, which easily causes the adjustment tray to be forced to deflect, thereby damaging the worm in the driving assembly.

[0022] Step 1: Place the rearview mirror housing in the receiving mold, use the robotic arm to drive the mounting frame to move, use the fixed tube to adsorb the center of the mirror surface, and transfer the mounting frame to the top of the receiving mold;

[0023] Step 2: The lifting drive module drives the two transmission arm assemblies to deflect downward, so that the two touch-pressure rods rotate to below the mirror surface, and then the mechanical arm drives the mounting frame to move downward, so that the two touch-pressure rods contact the adjustment tray, and the touch-pressure rods are squeezed and retracted relative to the mounting frame.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. Through the setting of the differential deflection mechanism, after the suction cup adsorbs the center position of the mirror, the lifting drive module drives the two touch-pressure rods to rotate to the bottom of the mirror, and then the mechanical arm drives the mounting frame to move downward, so that the two touch-pressure rods are in contact with the adjustment tray. When the adjustment tray is tilted, the two touch-pressure rods are squeezed and moved upward by different amounts, and then the touch-pressure rods drive the two offset push rods to move up and down through the differential deflection mechanism. When the tilt angle of the adjustment tray is larger, the distance that the two offset push rods move toward each other is larger, and the offset push rods contact the mirror to tilt it, so that the tilt angle of the mirror is consistent with the tilt angle of the tray, which facilitates the parallel clamping of the mirror and the tray, and avoids the tray being forced to deflect due to uneven contact when the mirror and the tray are squeezed and clamped, thereby damaging the internal gears or structures of the adjustment tray;

[0028] 2. Through the arrangement of the transmission arm assembly, when the mounting frame moves downward, the touch pressure rod contacts and squeezes the tray, and the touch pressure rod drives the gear rod 2 to move upward relative to the outer tube, driving the corresponding bevel gear 1 to rotate, and the bevel gear 1 drives the adjacent flat gear 2 to rotate. Since the two transmission arm assemblies in the same group are arranged symmetrically, when the two touch pressure rods are retracted, the two flat gears 2 on the differential deflection mechanism rotate in opposite directions, and the rotation angle of the flat gear 2 is related to the retraction amount of the corresponding touch pressure rod, and since the bevel gear 2 is located between the two flat gears 2 and is aligned with the two flat gears 2 When the adjustment tray is tilted, the two pressure rods have different upward retraction amounts, resulting in different rotation angles of the two flat gears 2, thereby driving the bevel gear 2 to rotate and revolve at the same time, thereby driving the central axis to rotate, and the rotation angle of the central axis is positively correlated with the difference in the retraction amount of the two pressure rods. The rotation of the central axis drives the two offset push rods to move up and down, thereby tilting the mirror surface to be parallel to the adjustment tray, so that the parallelism of the mirror surface and the adjustment tray is achieved by mechanical transmission, and this process is completed in the project where the mirror surface is close to the adjustment tray, reducing process time and improving efficiency.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 to Figure 6In an embodiment of the present invention, a vehicle rearview mirror assembly device includes a mechanical arm, a mounting frame 100, a lifting drive module 200, a differential deflection mechanism 300, an offset push rod 400, a transmission arm assembly 500, a touch pressure rod 600 and a receiving mold 700, wherein the receiving mold 700 is used to clamp and limit the rearview mirror housing, a connecting rod 110 is fixedly connected to the middle position of the mounting frame 100, a fixing plate 120 is fixedly connected to the bottom end of the connecting rod 110, a fixing tube 130 is fixedly connected to the bottom end of the fixing plate 120, a suction cup is fixedly connected to the bottom end of the fixing tube 130, and the number of differential deflection mechanisms 300 is two, and the two differential deflection mechanisms 300 are respectively installed at the two end positions of the fixing plate 120, and the number of transmission arm assemblies 500 is four, and the plurality of transmission arm assemblies 500 Two are arranged in a group, and the two groups of transmission arm assemblies 500 correspond to the two differential deflection mechanisms 300 respectively, and a touch-pressure rod 600 is fixedly connected between the bottom ends of the two transmission arm assemblies 500 located on the same side. There are two lifting drive modules 200, and the two lifting drive modules 200 correspond to the two groups of transmission arm assemblies 500 respectively. The lifting drive modules 200 are fixedly installed on the mounting frame 100, and the lifting drive modules 200 are used to drive the corresponding transmission arm assemblies 500 to deflect. There are two offset push rods 400, and the two offset push rods 400 are respectively slidably installed at the two end positions of the side bracket 140, and the offset push rods 400 are used to tilt the mirror surface. The mechanical arm is fixedly installed between the mounting frame 100, and the mechanical arm is used to drive the mounting frame 100 to move.

[0033] Specifically, after the rearview mirror housing is placed in the receiving mold 700, the mounting frame 100 is moved by the mechanical arm, the center position of the mirror surface is adsorbed by the suction cup under the fixing tube 130, and the mounting frame 100 is moved to the top of the receiving mold 700, and the lifting drive module 200 drives the two transmission arm assemblies 500 to deflect downward, so that the two touch-pressure rods 600 rotate to the bottom of the mirror surface, and then the mechanical arm drives the mounting frame 100 to move downward, so that the two touch-pressure rods 600 are in contact with the adjustment tray, and the touch-pressure rods 600 are squeezed and retracted relative to the mounting frame 100. When the adjustment tray is tilted, the retraction amounts of the two touch-pressure rods 600 are different, and then the touch-pressure rods 600 drive the two offset push rods 4 through the differential deflection mechanism 300. 00 moves up and down, and the up and down movement distance of the offset push rod 400 is only related to the difference in the retraction amount of the two contact pressure rods 600, that is, when the inclination angle of the adjustment tray is larger, the distance that the two offset push rods 400 move toward each other is larger, one offset push rod 400 moves up, and the other offset push rod 400 moves down to tilt the mirror surface, so that the inclination angle of the mirror surface is consistent with the inclination angle of the tray, which is convenient for the mirror surface and the tray to be parallelly connected, and avoids the tray being forced to deflect due to uneven contact when the mirror surface and the tray are squeezed and connected, thereby damaging the internal gears or structures of the adjustment tray. Embodiment 1

[0034] like Figures 4 to 8 As shown, in this embodiment, the transmission arm assembly 500 also includes an arm 510, the top of the arm 510 is transmission-connected to the top of the differential deflection mechanism 300, the bottom of the arm 510 is fixedly connected to an outer tube 540, the bottom of the outer tube 540 is slidably sleeved with a gear rod 2 541, the top inner wall of the arm 510 is rotationally connected to a circular shaft 1 520, the bottom of the arm 510 is rotationally connected to a circular shaft 2 530, the circular shaft 1 520 is transmission-connected to the circular shaft 2 530, the outer wall of the circular shaft 1 520 is fixedly connected to The transmission gear 1 521, the outer wall of the circular shaft 2 530 is fixedly connected with the transmission gear 2 531, the transmission gear 2 531 is meshed with the gear rod 2 541, the gear rod 2 541 is fixedly connected with the adjacent touch-pressure rod 600, the lifting drive module 200 includes a telescopic cylinder 210, the top of the telescopic cylinder 210 is fixedly connected with the mounting frame 100, the outer wall of the arm 510 is rotatably connected with the crank arm 230, the output end of the telescopic cylinder 210 is fixedly connected with the connecting seat 220, the crank arm 230 is connected with the adjacent connecting seat 2 20 are rotatably connected, the differential deflection mechanism 300 includes a fixing frame 310, the fixing frame 310 is fixedly connected to the fixing plate 120, both ends of the fixing frame 310 are rotatably connected with sleeves 311, the top of the arm 510 is rotatably sleeved with the adjacent sleeve 311, and the two transmission arm assemblies 500 of the same group are designed to be centrally symmetrical, the inner walls of the two sleeves 311 are rotatably connected with the central axis 320, the middle position of the sleeve 311 is fixedly sleeved with the right bevel gear 1 313, and one end of the sleeve 311 A flat gear 2 312 is fixedly sleeved on the outer wall, a sleeve seat 330 is fixedly sleeved on the middle position of the central shaft 320, one end of the sleeve seat 330 is rotatably connected to a bevel gear 2 331, the bevel gear 2 331 is located between the two flat gears 2 312, and the bevel gear 2 331 is meshed with the two flat gears 2 312, the arm 510 is in a broken line shape, the circular shaft 1 520 and the circular shaft 2 530 are transmission connected and rotate synchronously, and a reset spring is installed between the top end of the gear rod 2 541 and the inner top wall of the outer tube 540.

[0035] In this embodiment, the output end of the telescopic cylinder 210 drives the connecting seat 220 to move downward, and the connecting seat 220 drives the arm 510 to deflect downward through the curved arm 230, so that the two touch-pressure rods 600 deflect to the bottom of the mirror surface. When the mounting frame 100 moves downward, the touch-pressure rod 600 contacts and squeezes the tray, so that the touch-pressure rod 600 moves upward and retracts relative to the mounting frame 100, and the touch-pressure rod 600 drives the gear rod 2 541 to move upward relative to the outer tube 540. The outer tube 540 moves upward through the transmission gear 2 531. The second circular shaft 530 is driven to rotate, the rotation of the second circular shaft 530 drives the first circular shaft 520 to rotate, and the rotation of the first circular shaft 520 drives the transmission gear 1 521 to rotate. At this time, since the deflection angle of the arm 510 is fixed by the telescopic cylinder 210, the arm 510 keeps the angle unchanged, so the rotation of the transmission gear 1 521 directly drives the corresponding bevel gear 1 313 to rotate, and the bevel gear 1 313 drives the adjacent flat gear 2 312 to rotate. Since the two transmission arm assemblies 500 of the same group are centrally symmetrically arranged, When the two touch-pressure rods 600 are both retracted, the two flat gears 312 on the differential deflection mechanism 300 rotate in opposite directions, and the rotation angle of the flat gear 312 is related to the retraction amount of the corresponding touch-pressure rod 600. Since the bevel gear 331 is located between the two flat gears 312 and meshes with the two flat gears 312, when the adjustment tray is tilted, the upward retraction amounts of the two touch-pressure rods 600 are different, resulting in different rotation angles of the two flat gears 312, thereby driving the bevel gear 331 to rotate and revolve simultaneously, thereby driving the central shaft 320 to rotate, and the rotation angle of the central shaft 320 is positively correlated with the difference in the retraction amounts of the two touch-pressure rods 600. The rotation of the central shaft 320 drives the two offset push rods 400 to move up and down, thereby tilting the mirror surface to be parallel to the adjustment tray. The suction cup is generally made of rubber or other soft materials and can withstand a certain degree of deformation. Therefore, a certain degree of tilting of the mirror surface when the suction cup is adsorbed on the mirror surface will not cause the mirror surface to fall off.

[0036] The present invention also provides a method for assembling a rearview mirror for an automobile, which specifically comprises the following steps: Step 1: Place the rearview mirror housing in the receiving mold 700, drive the mounting frame 100 to move by the robot arm, adsorb the center of the mirror surface by the fixing tube 130, and transfer the mounting frame 100 to the top of the receiving mold 700; Step 2: The lifting drive module 200 drives the two transmission arm assemblies 500 to deflect downward, so that the two touch-pressure rods 600 rotate to below the mirror surface, and then the mechanical arm drives the mounting frame 100 to move downward, so that the two touch-pressure rods 600 contact the adjustment tray, and the touch-pressure rods 600 are squeezed and retracted relative to the mounting frame 100. When the adjustment tray is tilted, the retraction amounts of the two touch-pressure rods 600 are different, and then the touch-pressure rods 600 drive the two offset push rods 400 to move up and down through the differential deflection mechanism 300; Step 3: The two offset push rods 400 are driven to move toward each other, thereby driving the mirror surface to tilt, so that the tilt angle of the mirror surface is consistent with the tilt angle of the tray; Step 4: The lifting drive module 200 drives the transmission arm assembly 500 to rise and return to the initial position, and the mounting frame 100 moves downward to buckle the mirror on the pallet in a posture parallel to the pallet. Embodiment 2

[0037] like Figure 2 to Figure 6 As shown, in this embodiment, a transmission module 150 is arranged between the central shaft 320 and the two offset push rods 400. The central shaft 320 rotates through the transmission module 150 to drive the two offset push rods 400 to move up and down toward each other. The transmission module 150 includes two fixed seats 151. The top of the fixed seat 151 is fixedly connected to the side bracket 140, and the bottom end of the fixed seat 151 is rotatably connected to a flat gear 152. One end of the central shaft 320 is fixedly connected to a flat gear 340, which meshes with the flat gear 152. Both sides of the offset push rod 400 are fixedly connected to a gear rod 1 410, which meshes with the adjacent flat gear 152. The bottom end of the fixed plate 120 is fixedly connected to an electric push rod 160, and the bottom end of the electric push rod 160 is fixedly connected to a limiting seat 161. The limiting seat 161 is used to contact the central shaft 320 and limit the rotation of the central shaft 320.

[0038] In specific implementation, when the central shaft 320 rotates, the central shaft 320 drives the flat gears 152 on both sides to rotate through the flat gear 340, and the flat gear 152 drives the corresponding offset push rod 400 to move up and down through the gear rod 1 410, and makes the two offset push rods 400 move toward each other, so as to drive the mirror surface to tilt. When the mirror surface is level with the adjustment tray, the electric push rod 160 drives the limit seat 161 to move downward, so that the limit seat 161 conflicts with the central shaft 320, thereby limiting the rotation of the central shaft 320, and then makes the bevel gear 2 331 maintain the orbital position, and the offset push rod 400 and the mirror surface maintain the current posture, and then the telescopic cylinder 210 drives the transmission arm assembly 500 to rise, and the transmission arm assembly 500 revolves around the central shaft 320 When the arm 510 revolves upward, it drives the bevel gear 1 313 to rotate through the transmission gear 1 521, and since the position of the bevel gear 2 331 is fixed, the two bevel gears 1 313 rotate synchronously in opposite directions. When the mirror surface and the adjustment tray are engaged, the electric push rod 160 drives the limit seat 161 to release the restriction on the central axis 320, and 341 is reset under the drive of the reset spring, thereby driving the bevel gear 2 331 and the central axis 320 to reset.

[0039] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0040] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
