Detailed Description
Referring to fig. 1-7, a folding rearview mirror bracket comprises a mounting seat assembly, a folding structure assembly and a bracket main body.
The mounting seat combination consists of a mounting box and a positioning sleeve, wherein the mounting box is in a box shape with four or five closed surfaces, and the embodiment is four-sided closed. The space of the mounting box is sized to be capable of being assembled with a lower spring, a bolt and a gasket, and for assembly, any two symmetrical surfaces are turned into a flange (connecting plate) and bolt holes for assembly are machined on the flange. The surface opposite to the flanging is processed into a large round hole, and the locating sleeve passes through the hole and is located by steps to be welded with the mounting box. The center of the locating sleeve is provided with a proper through hole, and the outer end of the locating sleeve is provided with four first limit grooves with certain angles according to design requirements, in this example, symmetrical grooves with 90 degrees.
The folding structure combination is composed of a rotating structure and a first tension spring hanging pin. One end of the rotary structure is cylindrical (cylindrical section), the size of the cylinder is matched with the inner hole of the positioning sleeve, the rotary structure can rotate but cannot shake, the length of the rotary structure exceeds a proper amount of the positioning sleeve after the first tension spring hanging pin is limited, and a blind hole with internal threads is designed for installing a spring through a bolt; the cylindrical section is also provided with an axial through hole for assembling a first tension spring hanging pin, the first tension spring hanging pin has a positioning function, and annular grooves are formed at the two ends of the first tension spring hanging pin, so that the assembled tension spring can not fall off; the other end of the rotary structure is in a cuboid state, a strip-shaped hole is processed in a direction parallel to the axis of the cylindrical section through hole, the length and the width of the strip-shaped hole are determined according to design requirements, and the length and the position of the strip-shaped hole must be ensured to be positioned by a first tension spring hanging pin after assembly; the other direction of the cuboid is perpendicular to the axis, a straight groove is formed, half of the straight groove can not be opened due to the requirement of strength, and the width of the straight groove is matched with the machining width of the mounting rod of the bracket main body, so that the bracket main body can not shake after being mounted; symmetrical grooves (second limiting grooves) for limiting are designed on the end parts of the grooves in the direction perpendicular to the straight grooves; the direction of opening the straight groove is chamfered so as to ensure that the bracket main body is free from obstruction when being folded.
The bracket main body consists of a mounting rod, a second extension spring hanging pin, a rearview mirror supporting tube and a reinforcing tube. The mounting rod is in a cylindrical shape, one end of the mounting rod is processed into a flat square shape, the width of the mounting rod is matched with the width of the straight groove on the folding structure combination, the mounting rod cannot shake after being assembled, and the length of the mounting rod is shorter than that of the straight groove of the rotating structure; a round through hole is machined at the proper position of the tail end of the flat square, and the pin shaft is matched with the strip-shaped hole of the rotating structure through the through hole, so that the two parts are assembled and rotate by taking the pin shaft as the axis; the other end is also provided with a through hole for installing a second tension spring hanging pin which has a positioning function; the other end of the mounting rod is a cylinder with a positioning step, the cylinder is inserted into a hole of the rearview mirror support tube to be welded into a whole, the rearview mirror support tube is bent into a round angle L shape, and the axis of the round through hole is required to be coplanar with a plane formed by the L-shaped axis during welding, so that the inclination of the mounting part of the rearview mirror support bracket is ensured; the reinforcing pipe is welded on the rearview mirror support pipe to form a triangle, so that the strength of the rearview mirror support pipe is enhanced.
The installation method comprises the following steps:
The rotary structure 5-1 of the folding structure combination is assembled on the positioning sleeve 4-2 of the mounting seat combination, the compression spring 3 is arranged outside the rotary structure, then the gasket A2 is assembled on the bolt 1, and then the rotary structure is assembled on the internal threaded hole of the rotary structure 5-1, so that the compression spring 3 bears a certain precompression until the first tension spring hanging pin 5-2 of the folding structure combination falls into the positioning groove of the end surface of the positioning sleeve 4-2, and no axial movement and radial rotation occur.
Then the mounting rod 10-1 of the bracket main body is arranged in a straight groove of the rotary structure 5-1, the pin shaft 9 with a hole at the end part is inserted through a strip-shaped hole of the rotary structure 5-1 and a through hole of the mounting rod (flat square) 10-1, then the gasket B7 and the cotter pin 8 are arranged on the pin shaft 9, and the cotter pin 9 is bent to ensure reliable assembly.
Then, the two tension springs 6 are respectively assembled into the first tension spring hanging pin 5-2 of the folding structure combination and the annular grooves at two ends of the second tension spring hanging pin 5-2 of the bracket main body, so that the tension springs 9 cannot fall off. The mirror housing is then assembled to the mirror bracket assembly and finally the entire assembly is assembled to the vehicle by passing bolts through the bolt holes of the mounting box 4-1.
When the rearview mirror is folded, the folding structure combination is held to be pulled outwards, the compression spring 3 is shortened until the first tension spring hanging pin 5-2 of the folding structure combination is completely separated from the first limiting groove at the end part of the positioning sleeve 4-2 of the mounting seat combination, at the moment, the folding structure combination is rotated according to a set angle, the tension spring hanging pin 5-2 is rotated to the other first limiting groove, then the folding structure combination is released, the folding structure combination automatically returns under the action of the compression spring 3, and the assembly is completed again, but the height of the rearview mirror support is reduced as shown in fig. 6. At this time, the bracket main body is held and pulled outwards, the bracket main body moves outwards by taking the strip-shaped hole of the rotating structure 5-1 as a guide, the extension spring 6 stretches until the second extension spring hanging pin 5-2 of the bracket main body completely leaves the second limit groove at the end part of the rotating structure 5-1, at this time, the bracket main body is folded towards the opening direction of the straight groove by taking the pin shaft 9 as the axis, the extension spring 6 shortens, and the bracket main body is pulled back to complete folding, and the width is reduced as shown in figure 7. The vehicle is operated in the opposite mode when driving, and the installation of the rearview mirror and the recovery period function can be completed.
Through twice rotation, fold the rear-view mirror support, under the circumstances that does not influence its service function, satisfy the transportation requirement. The invention has convenient and quick operation and reasonable and reliable structure.
Finally, it is noted that the above-mentioned preferred embodiments are only intended to illustrate rather than limit the invention, and that, although the invention has been described in detail by means of the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the invention as defined by the appended claims.
