DETAILED DESCRIPTION

[0029] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of an interior rearview mirror assembly of the utility model in conjunction with the accompanying drawings.

[0030] The utility model can be applied to improve the structure of the interior rearview mirror of an automobile, and solves the technical problem in the prior art that the connection components of the interior rearview mirror are prone to loosening after the vehicle has been running for a long time, resulting in loosening and shaking of the interior rearview mirror after the vehicle has been running for a long time.

[0031] See also Figure 1 and Figure 2 , based on the technical problems solved above, the utility model discloses an interior rearview mirror assembly for installation on a vehicle body structure, including a mirror body assembly 100 and a connecting seat 200, one end of the connecting seat 200 has a ball head 201, and the other end is used for installation on the vehicle body structure;

[0032] The mirror body assembly 100 is provided with a ball head seat 106, and the ball head seat 106 has a clamping ring 107. The ball head 201 can be clamped in the clamping ring 107. The ball head seat 106 can rotate around the ball head 201, thereby driving the mirror body assembly 100 to rotate around the ball head 201, so as to achieve angle adjustment of the mirror body assembly 100;

[0033] An annular spring 108 is sleeved on the outer circumference of the clamping ring 107. When the ball head 201 is clamped with the clamping ring 107, the annular spring 108 can be deformed radially outward, so that the annular spring 108 can exert a reverse elastic force on the clamping ring 107 toward the center of the clamping ring 107.

[0034] The snap ring 107 is provided with a snap buckle 113 , and the snap buckle 113 can be snapped with one end of the annular spring 108 to limit the annular spring 108 .

[0035] In this solution, the annular spring 108, the clamping ring 107, and the ball head 201 are squeezed and locked with each other, which can prevent the mirror body assembly 100 from accidentally sliding or loosening due to road bumps or vibrations, and make it difficult for the ball head 201 to slide out of the ball head seat 106, thereby increasing the stability of the connection and helping to ensure that the mirror body assembly 100 remains at the angle selected by the driver; during driving, the vehicle may be subject to bumps and vibrations, which may cause the rearview mirror to shake, and the annular spring 108 can reduce these vibrations to a certain extent, protect the mirror body assembly 100, and make it more stable; the matching of the ball head 201 and the ball head seat 106 The annular spring 108 can provide some damping effect, so that the adjustment of the angle of the mirror body assembly 100 is smoother. Such a design can ensure that the driver will not be inconvenienced by excessive resistance or too loose feeling when adjusting the rearview mirror. In addition, the buckle 113 is provided, so that the annular spring 108 can be firmly mounted on the outer periphery of the clamping ring 107, which can not only prevent the annular spring 108 from jumping out, but also further limit the various components, so that when the car is driving, the shaking amplitude between the various components is smaller and the operation is more stable.

[0036] As a preference, see Figure 4 and Figure 5 A plurality of elastic latch teeth are arranged on the peripheral side of the snap ring 107, and each of the elastic latch teeth is evenly distributed around the circumference, and the inner circumference size of the central area enclosed by the elastic latch teeth is smaller than the maximum outer circumference size of the ball head 201; when the ball head 201 is snapped with the ball head seat 106, the part with the largest outer circumference size of the ball head 201 passes through the central area enclosed by each of the elastic latch teeth. At this time, each of the elastic latch teeth deforms radially outward, so that the ball head 201 extends into the ball head seat 106. When the part with the largest outer circumference size of the ball head 201 passes through the snap ring 107, each of the elastic latch teeth is reset to limit the ball head 201, and at the same time, the ball head 201 can rotate in the snap ring 107.

[0037] Preferably, the buckle 113 is arranged at one of the elastic teeth, and the buckle 113 extends from the outer edge of the elastic tooth toward a direction away from the central area. When the annular spring 108 is installed on the outer periphery of the clamping ring 107, the buckle 113 can limit the annular spring 108.

[0038] As a preference, see Figure 4 The buckles 113 are provided with two buckles, which are respectively provided on two axially symmetrical elastic buckles and extend from the outer edges of the two elastic buckles toward the direction away from the central area. In this way, both sides of the annular spring 108 can have a limiting structure, so that the fixing of the annular spring 108 is more stable.

[0039] As a preference, see Figure 5 The buckles 113 are provided with three buckles, which are respectively provided on three centrally symmetrical elastic buckles and extend from the outer edges of the three elastic buckles toward the direction away from the central area. In this way, the annular spring 108 can have a three-point limiting structure, making the fixing of the annular spring 108 more stable.

[0040] As a preference, see Figure 3 The mirror body assembly 100 includes a lens 101 and a frame 102. A placement position 103 for the lens 101 is set on one side of the frame 102. The lens 101 is fixed to the surface of the placement position 103. A mirror shell 104 is clamped on the peripheral side of the side of the frame 102 away from the lens 101. The ball head seat 106 is installed at the center position of the side of the frame 102 away from the lens 101. Correspondingly, a connecting hole 105 is opened on the mirror shell 104. The clamping ring 107 of the ball head seat 106 extends out from the connecting hole 105 and is clamped with the ball head 201. Specifically, the ball head seat 106 is fixed to the frame 102 by 4 ST3.5×9.5 screws.

[0041] As a preferred option for lens assembly, please refer to Figure 3 The lens 101 is attached to the placement position 103 on the surface of the frame 102 through the adhesive material layer 111. The placement position 103 has a plurality of convex strips extending along the placement position surface, and an exhaust groove is provided between two adjacent convex strips. In this way, it is not easy to generate bubbles when attaching the adhesive material layer 111, so that the attachment is more firm; after attaching the lens 101 to the frame 102, the frame 102 and the mirror shell 104 are clamped together, so that the lens, the frame and the mirror shell are assembled.

[0042] This preferred solution for lens assembly can solve the technical problem that, due to the lack of a bezel structure, the lens of the frameless interior rearview mirror is difficult to be compressed by the interaction force formed between the bezel and the mirror shell, which easily leads to an increased possibility of the lens falling off, thereby improving the assembly feasibility of the frameless interior rearview mirror.

[0043] Specifically, the adhesive material layer 111 is made of double-sided tape.

[0044] As a preference, see Figure 3 The lens 101 is a frameless anti-glare lens. A printed circuit board 109 (PCB board) is fixed to the back of the frame 102. An electronic anti-glare circuit is provided on the PCB board. The lens 101 is electrically connected to the electronic anti-glare circuit through a wiring harness. The electronic anti-glare circuit can adjust the color of the mirror electroplating layer of the lens 101.

[0045] Specifically, the PCB board is fixed on the mirror frame 102 by two ST2.2×6.5 screws.

[0046] As one specific implementation of the electronic anti-glare circuit being able to adjust the color of the mirror electrochemical layer of the lens 101, please refer to Figure 2 and Figure 3 An ambient light sensor is disposed on the printed circuit board 109, and a light-transmitting cover 110 is disposed on the mirror housing 104 at a position corresponding to the ambient light sensor. The light-transmitting cover 110 is snap-fitted to the mirror housing 104, and the ambient light sensor can sense external ambient light through the light-transmitting cover.

[0047] At present, the application of electronic anti-glare circuits for rearview mirrors is relatively common and belongs to conventional existing technologies. When the ambient light is bright, the electronic controller in the electronic anti-glare circuit will output an electrical signal to the conductive layer of the rearview mirror, causing the conductive layer to change the color of the mirror electrochemical layer (the higher the voltage, the darker the color), thereby making the light reflected by the rearview mirror darker and less glaring. However, this circuit requires the cooperation of the ambient light sensor to send the state signal of the sensed ambient light to the electronic controller in the electronic anti-glare circuit. Therefore, such an arrangement of the ambient light sensor can make it cooperate with the electronic anti-glare circuit to realize the automatic anti-glare function of the rearview mirror.

[0048] In the prior art, the back of the metal connector of the rearview mirror assembly is often exposed, the wiring harness assembly is exposed, the structure is easily damaged, and the appearance is not beautiful. Therefore, as a preferred method, please refer to Figure 3A cavity is also provided in the connection seat 200, and a detachable back plate 202 is provided on the cavity. The cavity is used to place the wiring harness assembly 112, and a notch is provided at one end of the connection seat 200 connected to the vehicle body structure; the ball head 201 is also a hollow structure, and the end of the ball head 201 facing the inside of the mirror body assembly 100 has a wire hole, one end of the wiring harness assembly 112 is inserted into the printed circuit board 109, and the other end passes through the wire hole into the cavity and passes out from the notch, and is then electrically connected to the vehicle body control system.

[0049] In addition, the prior art has a split connecting seat, which is costly and complex to assemble, and easily increases assembly errors, resulting in larger deviations in overall external dimensions. Therefore, as a preference, the connecting seat used in the present invention is an integrated metal connecting seat, which is integrally formed during production to reduce manufacturing errors, assembly errors, and assembly difficulty.

[0050] Specifically, the back plate is detachably connected to the connecting seat via M5*10 screws with anti-loosening glue.

[0051] The following technical effects are achieved by adopting an interior rearview mirror assembly disclosed by the utility model:

[0052] The utility model adds a buckle on the elastic clamping teeth of the ball head seat to limit the annular spring, so that the annular spring, the ball head seat and the connecting seat are fastened and locked through the interaction force, and the overall structure is more stable, thereby making the optical vibration, natural frequency, dislocation force and mirror body adjustment torque of the interior rearview mirror assembly more stable and reliable.

[0053] The connecting seat of the utility model is an integrated metal connecting seat, which is easy to assemble and has a smaller overall dimensional error after assembly; compared with a split connecting seat structure, it can save assembly parts and reduce assembly costs.

[0054] The utility model adds a cover plate on the back of the connecting seat, which makes the connecting seat more beautiful, and can also add a structure to fix the wiring harness inside to prevent the wiring harness from hitting surrounding parts and generating abnormal noise.

[0055] The frameless interior rearview mirror of the present invention has no mouth ring structure, so the lens cannot be compressed by the interaction force between the mouth ring and the mirror shell. The present invention adopts a method of adding adhesive material between the lens and the frame so that the lens is pasted on the frame. The vertical strips on the frame are exhaust structures, so that no bubbles are generated when the double-sided adhesive is pasted, thereby making the pasting more firm. The frame and the mirror shell adopt a snap-fit ​​structure. After the lens is pasted on the frame, the frame and the mirror shell are snap-fitted, so that the lens, the frame and the mirror shell can be assembled.
