[0001] This utility model relates to the field of electronic rearview mirror technology, and specifically discloses an electronic rearview mirror with stable connection. Background Technology

[0002] An electronic rearview mirror is an indirect field of view device that obtains a specified field of view through a system consisting of a camera and a monitor. It includes electronic equipment such as a high-definition camera, a digital vision processing system, a safety system, and an LCD display. It is a new type of rearview mirror that can replace traditional optical rearview mirrors. In order to improve vehicle driving safety, an electronic rearview mirror is needed.

[0003] Currently, when installing electronic rearview mirrors on vehicles that use optical rearview mirrors, the display screens of electronic rearview mirrors are mostly fixed by adhesive or simple brackets. However, adhesive or simple brackets cannot stably connect and install the display screens of electronic rearview mirrors. When the vehicle is bumpy during driving, the display screens of electronic rearview mirrors are prone to loosening, falling off or shifting, which seriously affects the stability of the field of vision and driving safety. Utility Model Content

[0004] This invention proposes a stable electronic rearview mirror that can stably connect and install the display screen of the electronic rearview mirror, avoiding the display screen from becoming loose, falling off, or shifting due to vehicle bumps, thus affecting the stability of the field of vision and driving safety.

[0005] This utility model is implemented as follows: a stable electronic rearview mirror includes a mounting plate and an electronic rearview mirror display screen, and a connecting mechanism is provided between the mounting plate and the electronic rearview mirror display screen.

[0006] The connecting mechanism includes an outer mounting cylinder fixedly connected to the right side wall of the mounting plate. The inner wall of the outer mounting cylinder has two symmetrically distributed slots.

The outer wall of the mounting post has two through holes that correspond to the two slots respectively. The inside of each of the two through holes is slidably connected to a locking pin that matches the two slots respectively.

[0007] As a preferred embodiment of the present invention for a stable electronic rearview mirror, a movable rod is provided inside the cavity. The left end of the outer wall of the movable rod is rotatably connected to two locking pins via hinges. The outer wall of the mounting column is provided with two sliding holes located to the right of the two through holes. Two symmetrically distributed connecting rods are fixedly connected to the right end of the outer wall of the movable rod. The other ends of the two connecting rods extend to the outside of the cavity through the two sliding holes respectively.

[0008] As a preferred embodiment of the present invention for a stable electronic rearview mirror, a movable cylinder is sleeved on the outside of the mounting column, and the other ends of the two connecting rods are slidably connected to the inner wall of the movable cylinder. Two symmetrically distributed limiting pins are fixedly connected to the inner wall of the movable cylinder. Two notches are opened at the right end of the outer wall of the mounting outer cylinder, which are respectively matched with the two limiting pins. Each of the two notches has a limiting groove on its inner sidewall that is respectively matched with the limiting pin.

[0009] As a preferred embodiment of the present invention for a stable electronic rearview mirror, the left inner sidewall of the notch is provided with a groove located on one side of the limiting groove, a retaining ball is provided inside the groove, and a spring is fixedly connected between the groove and the retaining ball.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A stable electronic rearview mirror includes a mounting plate 1 and an electronic rearview mirror display screen 2, with a connection mechanism provided between the mounting plate 1 and the electronic rearview mirror display screen 2.

[0021] The connecting mechanism includes an outer mounting cylinder 3 fixedly connected to the right side wall of the mounting plate 1. The inner wall of the outer mounting cylinder 3 has two symmetrically distributed slots 4. The left side wall of the electronic rearview mirror display screen 2 is fixedly connected to a mounting post 5 that matches the outer mounting cylinder 3. The mounting post 5 has a cavity 6 inside. The outer wall of the mounting post 5 has two through holes 7 that correspond to the two slots 4 respectively. The inside of each of the two through holes 7 is slidably connected to a locking pin 8 that matches the two slots 4 respectively.

[0022] In this embodiment: During installation, the mounting plate 1 is first installed in the vehicle at a position suitable for the driver's observation using bolts. Then, the mounting post 5 is inserted into the mounting outer cylinder 3 through the electronic rearview mirror display screen 2, so that the two through holes 7 are aligned with the two slots 4. Then, the two locking pins 8 move in opposite directions, so that the two locking pins 8 are removed from the two through holes 7 and enter the two slots 4 respectively. Then, the mounting post 5 is locked and fixed in the mounting outer cylinder 3 through the mutual cooperation between the two locking pins 8 and the two slots 4, thereby stably connecting and installing the electronic rearview mirror display screen 2, avoiding the electronic rearview mirror display screen from loosening, falling off or shifting due to vehicle bumps, which would affect the stability of the field of vision and driving safety.

[0023] When disassembling the electronic rearview mirror display screen 2, the two locking pins 8 move in opposite directions, causing them to move out of their respective locking pins 8 and into their respective through holes 7, thereby releasing the locking and fixing state of the mounting post 5. This facilitates the quick and easy disassembly of the electronic rearview mirror display screen 2 for maintenance and repair.

[0024] As a technical optimization of this utility model, a movable rod 9 is provided inside the cavity 6. The left end of the outer wall of the movable rod 9 is rotatably connected to the two locking pins 8 through a hinge seat and a pull rod 10. The outer wall of the mounting column 5 is provided with two sliding holes 11 located to the right of the two through holes 7. The right end of the outer wall of the movable rod 9 is fixedly connected to two symmetrically distributed connecting rods 12. The other ends of the two connecting rods 12 extend to the outside of the cavity 6 through the two sliding holes 11 respectively.

[0025] In this embodiment: after the mounting post 5 is inserted into the mounting outer cylinder 3, the two connecting rods 12 move to the left, and the two connecting rods 12 drive the moving rod 9 to move to the left. The moving rod 9, together with the two pull rods 10, pushes the two locking pins 8 to move in opposite directions.

[0026] As a technical optimization of this utility model, a movable cylinder 19 is sleeved on the outside of the mounting column 5. The other ends of the two connecting rods 12 are slidably connected to the inner wall of the movable cylinder 19. Two symmetrically distributed limiting pins 13 are fixedly connected to the inner wall of the movable cylinder 19. Two notches 14 are opened at the right end of the outer wall of the mounting outer cylinder 3, which are respectively matched with the two limiting pins 13. The inner side wall of the two notches 14 is provided with limiting grooves 15 that are respectively matched with the limiting pins 13.

[0027] In this embodiment: the movable cylinder 19 is pushed to the left, and the movable cylinder 19 drives the two connecting rods 12 to move to the left. When the two connecting rods 12 cooperate with the movable rod 9 and the two pull rods 10 to push the two locking pins 8 into the two locking slots 4 respectively, the two limiting pins 13 enter the two notches 14 respectively. Then the movable cylinder 19 is rotated, and the movable cylinder 19 drives the two limiting pins 13 into the two limiting grooves 15 respectively. Then, through the mutual cooperation between the two limiting pins 13 and the two limiting grooves 15, the movable cylinder 19 is restricted and fixed at the right end of the outer cylinder 3. Thus, the movable rod 9, the two pull rods 10 and the two locking pins 8 are restricted by the fixed movable cylinder 19, preventing the two locking pins 8 from disengaging from the two locking slots 4 respectively.

[0028] As a technical optimization of this utility model, a groove 16 located on one side of the limiting groove 15 is provided on the left inner side wall of the notch 14. A retaining ball 17 is provided inside the groove 16, and a spring 18 is fixedly connected between the groove 16 and the retaining ball 17.

[0029] In this embodiment: when the moving cylinder 19 rotates and drives the two limiting pins 13 into the two limiting grooves 15 respectively, the two limiting pins 13 can squeeze the two retaining balls 17 into the two grooves 16 respectively. The compression of the two retaining balls 17 causes the two springs 18 to contract, generating a rebound force. After the two limiting pins 13 are fully inserted into the two limiting grooves 15, the two springs 18 push the two retaining balls 17 to reset, thereby axially limiting the moving cylinder 19 and preventing the moving cylinder 19 from rotating arbitrarily on the outer wall of the outer cylinder 3.

[0030] As a technical optimization of this utility model, the two connecting rods 12 and the moving cylinder 19 are slidably connected by a limiting slider and an annular limiting groove.

[0031] In this embodiment, the moving cylinder 19 can rotate smoothly by means of the limiting slider and the annular limiting groove.

[0032] As a technical optimization of this utility model, the through hole 7 and the locking pin 8 are slidably connected by a limiting slider and a limiting groove.

[0033] In this embodiment, the locking pin 8 can be limited by the limiting slider and the limiting groove to prevent the locking pin 8 from coming out of the through hole 7.

[0034] The working principle and usage process of this utility model are as follows: During installation, the mounting plate 1 is first installed in the vehicle at a position suitable for the driver's observation using bolts. Then, the mounting post 5 is inserted into the mounting outer cylinder 3 through the electronic rearview mirror display screen 2, aligning the two through holes 7 with the two slots 4. The moving cylinder 19 is then pushed to the left, causing the two connecting rods 12 to move to the left. When the two connecting rods 12, in conjunction with the moving rod 9 and the two pull rods 10, push the two locking pins 8 into the two slots 4 respectively, the mounting post 5 is locked and fixed inside the mounting outer cylinder 3 through the mutual cooperation between the two locking pins 8 and the two slots 4. Simultaneously, the two limiting pins 13 enter the two notches 14 respectively. Then, the moving cylinder 19 is rotated, causing the two limiting pins 13 to enter the two limiting grooves 15 respectively, thus securing the mounting post 5 within the mounting outer cylinder 3. The interaction between pin 13 and the two limiting grooves 15 restricts and fixes the movable cylinder 19 to the right end of the mounting outer cylinder 3. When the movable cylinder 19 rotates, the two limiting pins 13 can squeeze the two retaining balls 17 into the two grooves 16 respectively. The compression of the two retaining balls 17 causes the two springs 18 to contract, generating a rebound force. After the two limiting pins 13 are fully inserted into the two limiting grooves 15, the two springs 18 push the two retaining balls 17 to reset. Then, the two retaining balls 17 axially limit the movable cylinder 19, preventing the movable cylinder 19 from rotating freely on the outer wall of the mounting outer cylinder 3. Thus, the fixed movable cylinder 19 restricts the movable rod 9, the two pull rods 10 and the two retaining pins 8, preventing the two retaining pins 8 from disengaging from the two retaining grooves 4 respectively, thereby stably connecting and installing the electronic rearview mirror display screen 2.
