[0002] Rearview mirrors are crucial components for ensuring driving safety, providing drivers with a clear view of what's behind the vehicle. With advancements in automotive industrial design, frameless rearview mirrors are gaining increasing popularity due to their simplicity, aesthetics, and wide field of vision.

[0003] The lens body and the outer shell are mainly fixed by adhesive or threaded connection. Although adhesive connection is simple in structure, it is difficult to disassemble once fixed. The adhesive also has the risk of falling off after aging. Furthermore, the lens or outer shell is easily damaged during disassembly, making it impossible to reuse.

[0004] The threaded connection method usually requires drilling mounting holes at the rear end of the frameless rearview mirror housing and using screws for fastening. This method not only affects the overall appearance of the product, but also requires special tools for installation and disassembly, which is cumbersome and inefficient, and is not conducive to the quick installation and removal of the mirror. Utility Model Content

[0005] Given that the existing methods of fixing the lens body and the outer shell mainly rely on adhesive or threaded connection, which are not conducive to the quick installation and removal of the lens, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a frameless car rearview mirror, which aims to achieve convenient, fast, and non-destructive installation of the lens.

[0007] To solve the above technical problems, this utility model provides the following technical solution: a frameless car rearview mirror, including a mounting shell and a mounting bracket installed in the middle of the rear end of the mounting shell. The front end face of the mounting shell is detachably mounted with a frameless mirror body. Each of the four corners inside the mounting shell is equipped with a snap-fit ​​seat. Each of the four corners of the frameless mirror body near one end of the mounting shell is fixed with a fixing square post. The snap-fit ​​seat near one end of the frameless mirror body has a snap-fit ​​cavity that snaps into the fixing square post. The inner side of the card holder is provided with an inlet and outlet hole that communicates with the card cavity. An elastic translation mechanism is installed on the side of the card holder near the inlet and outlet hole. The movable end of the elastic translation mechanism is fixed with a plum blossom card post. The end face of the fixed square post near the inlet and outlet hole is provided with a plum blossom card groove that engages with the plum blossom card post. A magnetic drive mechanism is installed in the middle of the interior of the mounting shell.

[0008] As an improved technical solution, the middle part of the tail end of the mounting shell is provided with a concave cavity, and a universal joint is provided inside the concave cavity. The universal joint is fixed to the end of the mounting bracket near the mounting shell.

[0009] As an improved technical solution, an elastic strip is provided at the joint between the mounting shell and the frameless mirror body, and the elastic strip is bonded and fixed to the edge of the mounting shell.

[0010] As an improved technical solution, the elastic translation mechanism includes two T-shaped rods fixed to the side of the locking seat near the inlet / outlet hole, a translation block is slidably installed between the two T-shaped rods, and a second spring is sleeved on the cross end of the T-shaped rod and the end of the translation block away from the plum blossom locking post.

[0011] As an improved technical solution, the magnetic drive mechanism includes a translation frame that slides inside the mounting housing. Each of the four corners of the translation frame is fixed with a mounting base. A first magnet is embedded in the side of the mounting base away from the translation frame. A second magnet is fixed in the middle of the end face of the translation block away from the plum blossom-shaped locking post.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Example 1 Reference Figures 1-4 This is the first embodiment of the present utility model, which provides a frameless car rearview mirror. This frameless car rearview mirror includes a mounting shell 1 and a mounting bracket 9 installed in the middle of the rear end of the mounting shell 1. The front end face of the mounting shell 1 is detachably mounted with a frameless mirror body 2. Each of the four corners inside the mounting shell 1 is equipped with a snap-fit ​​seat 4. Each of the four corners of the frameless mirror body 2 near one end of the mounting shell 1 is fixed with a fixing square post 3. The snap-fit ​​seat 4 near one end face of the frameless mirror body 2 is provided with a snap-fit ​​cavity 11 that snaps into the fixing square post 3. The inner side of the card holder 4 is provided with an inlet / outlet hole 13 that communicates with the card cavity 11. An elastic translation mechanism 5 is installed on the side of the card holder 4 near the inlet / outlet hole 13. The movable end of the elastic translation mechanism 5 is fixed with a plum blossom card post 12, and the plum blossom card post 12 passes through the inlet / outlet hole 13 and enters the interior of the card cavity 11. The fixed square post 3 is provided with a plum blossom card groove 10 that engages with the plum blossom card post 12 on one end face near the inlet / outlet hole 13. A magnetic drive mechanism 6 is installed in the middle of the interior of the mounting shell 1, and the drive end of the magnetic drive mechanism 6 is located at the tail end of the mounting shell 1.

[0023] The snap-fit ​​structure replaces the traditional adhesive or threaded connection, and the entire process can be completed in seconds without any tools or adhesives, greatly improving the efficiency of loading and unloading and enabling the rapid assembly and disassembly of the frameless lens body 2. At the same time, the rapid and non-destructive disassembly greatly facilitates the maintenance, cleaning or replacement of the frameless lens body 2 in the future. Furthermore, the snap-fit ​​structure provides uniform clamping force and sufficient holding force after locking, ensuring that the lens remains stable even in the vibration environment of vehicle driving.

[0024] The middle of the tail end of the mounting housing 1 is provided with a concave cavity 8. A universal joint is provided inside the concave cavity 8, and the universal joint is fixed to the end of the mounting bracket 9 near the mounting housing 1.

[0025] An elastic strip 7 is provided at the joint between the mounting shell 1 and the frameless mirror body 2, and the elastic strip 7 is bonded and fixed to the edge of the mounting shell 1. When the frameless mirror body 2 is installed on the mounting shell 1, the frameless mirror body 2 compresses the elastic strip 7. The elastic strip 7 is used to fill the gap between the mounting shell 1 and the frameless mirror body 2, thereby improving the sealing between the frameless mirror body 2 and the mounting shell 1.

[0026] The elastic translation mechanism 5 includes two T-shaped rods 53 fixed on the side of the locking seat 4 near the inlet / outlet hole 13. A translation block 51 is slidably installed between the two T-shaped rods 53, and a plum blossom locking post 12 is fixed on one end face of the translation block 51 near the locking seat 4. Both ends of the translation block 51 are provided with sliding holes for the cross bar ends of the T-shaped rods 53 to pass through. A second spring 54 is sleeved on the cross bar end of the T-shaped rod 53 and the end of the translation block 51 away from the plum blossom locking post 12.

[0027] The magnetic drive mechanism 6 includes a translation frame 61 that slides inside the mounting housing 1. Each of the four corners of the translation frame 61 is fixed with a mounting base 68. A first magnet 69 is embedded in the side of the mounting base 68 away from the translation frame 61. A second magnet 52 is fixed in the middle of the end face of the translation block 51 away from the plum blossom locking post 12. The four first magnets 69 are positioned opposite the four second magnets 52. The opposing surfaces of the first magnets 69 and the second magnets 52 are magnetically attracted to each other.

[0028] The magnetic drive mechanism 6 also includes hole blocks 63 fixed on both sides of the tail end face of the mounting shell 1. A light rod 62 is fixed on both sides of the rear end face of the translation block 51, and the light rod 62 extends through the central hole on the hole block 63 to the outside of the mounting shell 1. Circular through holes for the light rod 62 to pass through are opened on both sides of the rear end face of the mounting shell 1. A blocking block 65 is welded to the end of the light rod 62 away from the translation block 51. A first spring 64 is sleeved on the light rod 62 between the opposite surfaces of the hole block 63 and the blocking block 65.

[0029] A U-shaped bracket 66 is fixed between the two blocking blocks 65 at the end face away from the light rod 62. A thumb buckle bracket 67 is fixed at the lower part of the middle of the rear end face of the mounting shell 1. The U-shaped bracket 66 and the thumb buckle bracket 67 limit the five fingers, making it easier for the hand to apply pressure to the U-shaped bracket 66. A better point of force application helps to improve the efficiency of assembling and disassembling the frameless mirror body 2.

[0030] The working principle of this utility model is as follows: When continuing to assemble and disassemble the frameless mirror body 2, the thumb of one hand is inserted into the inner cavity of the thumb buckle 67, and the other four fingers are hooked on the back of the U-shaped frame 66. The four fingers simultaneously apply pressure towards the U-shaped frame 66 in the direction of the light rod 62, pushing the blocking block 65 to move towards the translation frame 61 and compressing the first spring 64. This will push the translation frame 61 forward, so that the first magnet 69 and the second magnet 52 are in a coaxial state. Under the magnetic attraction of the first magnet 69 and the second magnet 52, the second magnet 52 is pulled towards the second spring 54 and the second spring 54 is compressed, thereby pulling the plum blossom locking post 12 out of the inside of the locking cavity 11. At this time, the four fixed square posts 3 of the card holder 4 are inserted into the card cavity 11 of the four card holder 4 respectively. Then, the pressure applied to the U-shaped frame 66 is released, and it is reset under the elastic reset of the first spring 64. The first magnet 69 and the second magnet 52 are in a staggered state. After the magnetic attraction state is released, under the elastic reset of the second spring 54, 21 returns to the inside of the card cavity 11 and is engaged with the plum blossom card slot 10, thus completing the installation of the frameless mirror body 2. Similarly, after removing the plum blossom-shaped locking post 12 from inside the locking cavity 11, the frameless mirror body 2 can be pulled out from the outer side to complete the disassembly.
