Detailed Description

The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It should be understood that the description herein is provided for illustration and explanation of the invention and is not intended to limit the invention.

In the present invention, unless otherwise specified, the directional terms "facing, away, horizontal, inclined, front, rear, end" and the like included in the terms only represent the orientation of the terms in a conventional use state or a colloquial term understood by those skilled in the art, and should not be construed as limiting the terms.

Referring to fig. 5-9, a coupling mechanism is shown, the coupling mechanism comprising: the positioning piece 21 and the connecting piece 1 nested in the positioning piece 21; wherein,

the connecting piece 1 comprises a mounting end 15 and an adhering end 14 which are sequentially connected along the thickness direction, and the adhering end 14 is nested in the positioning piece 21;

two sides of the mounting end 15 are recessed inwards to form two vertical through side sliding grooves 11, and the front surface of the mounting end 15 is recessed inwards to form a spherical groove 13;

the top end of the mounting end 15 is inwards sunken to form a limiting groove 12 communicated with the side sliding groove 11, and the side sliding groove 11 and the limiting groove 12 are the same in width.

By implementing the above technical mode, the positioning member 21 is separated from the connecting member 1, and the positioning member 21 is only used for installing the connecting member 1. The production line of front windshield glass has frock placed in the middle and is used for fixing a position front windshield glass, and setting element 21 just can be connected with this frock placed in the middle, and setting element 21 connects behind the frock placed in the middle, and its relative position with front windshield glass just has been confirmed, locates the setting element 21 with connecting piece 1 cover this moment in, just can realize fixing a position connecting piece 1 to front windshield glass's purpose.

The connecting piece 1 comprises a mounting end 15 positioned in front and a pasting end 14 positioned in back, after the pasting end 14 of the connecting piece 1 is placed into the positioning piece 21, the connecting piece 1 can be pasted on the front windshield glass through the pasting end 14, and thus the guarantee of the position degree of the connecting piece 1 is realized.

The both sides of installation end 15 are inwards sunken to be formed with two vertical through-going side grooves 11, and this side groove 11 realizes the quick installation to the inside rear-view mirror through the mode of joint.

When the mode that uses the joint realizes being connected of connecting piece 1 and interior rear-view mirror, receive the influence of joint position fit clearance, the condition that interior rear-view mirror can appear rocking in this hookup location's fore-and-aft direction, and at the car in-process, this kind rocks and will produce the abnormal sound, is not allowed. A spherical groove 13 is provided on the front face of the mounting end 15 for positioning the interior mirror in the front-rear direction, and the interior mirror can be screwed into this spherical groove 13.

Because the rear-view mirror joint is in connecting piece 1 back, the moment of torsion that the torque that receives on sideslip groove 11 upper portion received is bigger than the moment of torsion that the lower part received, in order to improve the atress condition on side spout 11 upper portion, can extend side spout 11 upwards, shortens the distance between the top of sideslip groove 11 and the top of rear-view mirror. The purpose of extending the side sliding groove 11 upwards can be achieved by extending the limiting groove 12 at the upper part of the mounting end 15. While the retaining groove 12 also provides guidance for the installation of the assembly mount 43.

If the height of the mounting end 15 is directly increased instead of the limiting groove 12, the material used by the connecting piece 1 is inevitably increased under the condition that the length of the side grooves 11 is the same, and the limiting groove 12 is arranged to reduce the material cost under the condition of ensuring the structural strength of the connecting piece 1 because the connecting piece 1 is made of alloy.

In this embodiment, the edge of the application end 14 preferably extends 2-3mm outward relative to the edge of the mounting end 15.

In order to ensure that the bonding strength of the connecting piece 1 and the front windshield glass can better satisfy the supporting effect on the rearview mirror, the effective bonding surface of the bonding end 14 and the front windshield glass is required to cover the mounting end 15, the bonding end 14 can be set to be in the same structure as the mounting end 15 in shape, and the outer contour of the bonding end 14 can cover the outer contour of the mounting end 15. Preferably, the edge of the application end 14 extends 2-3mm outward relative to the edge of the mounting end 15.

In this embodiment, it is preferable that the depth of the stopper groove 12 is 1 to 2 mm.

Since the circumferential direction of the sticking end 14 is enlarged by 2-3mm compared with the circumferential direction of the mounting end 15, in order to ensure that the end part of the side chute 11 is still within the coverage range of the effective sticking surface of the sticking end 14 and the front windshield glass, the extending height of the limiting groove 12 can not be more than 2-3mm, and preferably, the limiting groove 12 can be extended upwards by a distance of 1-2mm, so that the force of the sticking surface of the sticking end 14 and the front windshield glass is not influenced while the force of the side chute 11 is improved.

In this embodiment, the connecting member 1 is preferably a bilaterally symmetrical structure, and the spherical groove 13 is provided at a central position in the width direction of the mounting end 15. The spherical groove 13 and the mounting screw 42 are required to be arranged at the center of the assembly mounting frame 43, so that the problem of unbalance of left and right stress of the assembly mounting frame 43 caused by offset is avoided.

In this embodiment, it is preferable that the opening radius of the spherical groove 13 is 3.8 to 4.2mm and the depth of the spherical groove 13 is 2.3 to 2.8 mm.

A relatively fixed connection between the assembly mount 43 and the connecting member 1 is required in order to limit play between the assembly mount 43 and the connecting member 1. Due to space constraints, the mounting screw 42 is disposed obliquely, and if an oblique threaded hole is formed in the mounting end 15 to match the mounting screw 42, the following difficulties may occur: firstly, the position of the threaded hole requires precision, and even the position of the bolt hole 44 on the assembly mounting bracket 43 including the corresponding threaded hole must have very high requirements to achieve smooth mounting of the screw 42 during the assembly process; then, the mounting screw 42 may not be normally mounted during the actual mounting process due to a manufacturing error or the like. This way of machining a threaded hole in the mounting end 15 to mate with the mounting screw 42 is clearly undesirable, it increases the difficulty of manufacturing the components, and it may still result in a loss of man-hours due to an installation failure of the mounting screw 42.

The present application employs a tightening of the mounting screw 42 into the spherical groove 13 to achieve a deflection of the assembly mounting bracket 43 away from the attachment 1 and ultimately secure the assembly mounting bracket 43 at the distal end. In the process, the assembly mounting frame 43 is provided with the bolt hole 44 matched with the mounting screw 42, the mounting screw 42 is firstly spirally pushed towards the spherical groove 13, then the mounting screw 42 abuts against the inner wall of the spherical groove 13, next, along with the spiral pushing of the mounting screw 42, the assembly mounting frame 43 is pushed away from the connecting piece 1 along with the bolt hole 44 until the assembly mounting frame 43 reaches the farthest position, the gap between the assembly mounting frame 43 and the connecting piece 1 at the clamping position is completely eliminated, at the moment, the mounting screw 42 is still spirally pushed towards the spherical groove 13, and because the assembly mounting frame 43 does not have a moving space, the mounting screw 42 is tapped towards the spherical groove 13, and the position can be ensured not to shake by tapping about 1mm generally.

The connecting piece 1 is made of alloy materials, and the spherical groove is processed on the surface of the alloy materials easily, so that the spherical groove 13 is more convenient to process when the surface is spherical.

The opening of the spherical groove 13 is large enough to accommodate the positional error of the bolt hole 44, i.e., the mounting screw 42 directed to any direction can enter the spherical groove 13 to come into contact with the spherical groove 13, and preferably, the opening radius of the spherical groove 13 is set to 3.8 to 4.2 mm.

The depth of the spherical recess 13 should not be too deep so that the mounting screw 42 can contact the side wall of the spherical recess 13 over a limited length thereof and can tap the side wall of the spherical recess 13 so that the assembly mount 43 is pushed out firmly, keeping the clearance of the engagement position of the assembly mount 43 with the connector 1 effectively eliminated. Preferably, the depth of the spherical groove 13 is set to 2.3-2.8 mm.

Referring to fig. 1-4, an in-vehicle assembly mount includes: the assembly mounting frame 43, the mounting screw 42 and the connecting mechanism, wherein one end of the assembly mounting frame 43 facing the connecting piece 1 is provided with a mounting slot 41 which can be inserted into the connecting piece 1 from top to bottom;

the rear end of the assembly mounting bracket 43 is provided with a bolt hole 44 extending towards the direction of the spherical groove 13, and the mounting screw 42 is screwed through the bolt hole 44 and then is pressed and contacted with the inner wall of the spherical groove 13;

the front end of the assembly mounting frame 43 is provided with a rearview mirror quick-mounting bulb 45.

Through the implementation of the technical mode, the in-vehicle assembly mounting frame 43 can be quickly mounted on the in-vehicle assembly mounting frame 43 through the clamping connection of the mounting slot 41 and the side sliding slot 11.

Meanwhile, the in-vehicle assembly mounting frame 43 is fixedly connected with the connecting piece 1 through the mounting screw 42, and the shaking between the in-vehicle assembly mounting frame 43 and the connecting piece 1 is avoided.

The rearview mirror can be directly inserted into the rearview mirror quick-mounting ball head 45, and the assembly mounting frame 43 is quickly connected with the inner rearview mirror.

In this embodiment, preferably, a stopper plate 47 is provided to extend rearward from the top of the assembly mounting bracket 43, and a stopper capable of being engaged with the stopper groove 12 is provided to a lower edge of the stopper plate 47.

There is a stop plate 47 at the top of the assembly mounting frame 43, and when the installation slot 41 is clamped with the side sliding slot 11, the stop plate 47 is matched with the limit groove 12 to limit the assembly mounting frame 43.

A more reliable snap fit can be achieved by the stop plate 47 being provided with a small stop projecting downwards.

In this embodiment, preferably, the bolt hole 44 extends obliquely upward toward one end of the spherical groove 13.

Due to the space constraints of the assembly mount, the mounting control of the mounting screws 42 can only be provided in the space below the assembly mount. In order to obtain a more suitable operation space and operation angle for the operator, the mounting screw 42 needs to be disposed obliquely so as to dispose the mounting space of the mounting screw 42 obliquely downward.

In this embodiment, the bolt hole 44 preferably has an angle of not less than 45 ° with the horizontal direction.

In order to obtain a more suitable operating space and operating angle for the operator, the mounting screws 42 need to be arranged obliquely, preferably with the bolt holes 44 at an angle of not less than 45 ° to the horizontal, so that the operator's tools, as well as the operator's hands, can enter the area for operation.

In this embodiment, the bottom side of the assembly mount 43 is preferably provided with a hollowed-out slot 46 extending in a direction parallel to the length direction of the mounting screw 42.

On the premise of ensuring the structural strength of the assembly mounting bracket 43, the bottom side of the assembly mounting bracket 43 is designed to be hollow, so that more mounting space can be provided for the mounting screw 42. The provision of the hollow-out slot 46 also reduces the weight of the assembly mounting bracket 43, and accordingly the durability of the use of the mirror assembly is also better ensured.
