[0028] Example 1

[0029] Reference Figure 1 to Figure 6, which is the first embodiment of the utility model, and this embodiment provides a vehicle-mounted rearview mirror backlight source, which includes a light source component 200, a rotating component 300 and an adjusting component 400. After the angle of the rearview mirror is adjusted, the backlight in the rearview mirror will move to a specified position as the rearview mirror is adjusted.

[0030] The light source assembly 200 includes a backlight 201a, a moving rod 201b, a hinged rod 201c and a rotating rod 201d. The moving rod 201b is fixed to one side of the backlight 201a, the hinged rod 201c is hinged to one side of the moving rod 201b, and the rotating rod 201d is hinged to one end of the hinged rod 201c.

[0031] There are two movable rods 201b, both of which are fixed on one side of the backlight 201a. There are two hinged rods 201c, both of which are hinged to one side of the movable rod 201b. The rotation of the rotating rod 201d will drive the two hinged rods 201c to move toward each other at the same time. The movement of the hinged rod 201c will drive the movable rod 201b to move. The movement of the movable rod 201b can drive the backlight 201a to move the backlight 201a to a suitable lighting position. The backlight 201a ensures that under different light conditions, especially in a dimly lit environment, the driver can clearly observe the situation behind the vehicle through the rearview mirror.

[0032] The rotating assembly 300 is arranged on one side of the backlight 201a, and includes a worm wheel 301a, a worm 301b, a first rotating wheel 301c, a pull rope 301d and a second rotating wheel 301e. The worm wheel 301a is arranged on one side of the rotating rod 201d, the worm 301b is arranged on the top of the worm wheel 301a, the worm 301b is meshed with the worm wheel 301a, the first rotating wheel 301c is fixed to one end of the worm 301b, the pull rope 301d is sleeved on the outside of the first rotating wheel 301c, and the second rotating wheel 301e is arranged inside the pull rope 301d.

[0033] When the angle of the rearview mirror 102 is adjusted, the second rotating wheel 301e will rotate, and the rotation of the second rotating wheel 301e will reel in the pull rope 301d to move it, and the movement of the pull rope 301d can drive the first rotating wheel 301c to rotate, and the rotation of the first rotating wheel 301c can drive the worm 301b to rotate, and the rotation of the worm 301b can drive the worm wheel 301a to rotate, and at this time, the rotation of the worm wheel 301a can drive the rotating rod 201d to rotate.

[0034] A movable column is provided on one side of the first rotating wheel 301c, and a connecting plate is sleeved on the outer side of the movable column. The connecting plate is movably connected to the movable column, and a connecting disk is fixed on one side of the movable column. A torsion spring is fixed on one side of the connecting disk, and the torsion spring is fixed to one side of the connecting plate. When the pull rope 301d moves to make the first rotating wheel 301c rotate, the movable column will be driven to rotate, and the connecting disk will be driven to rotate through the rotation of the movable column. The rotation of the connecting disk can apply a torsional force to the torsion spring. When the rearview mirror 102 is moved to the initial position, the second rotating wheel 301e will rotate at this time. The rotation of the second rotating wheel 301e will release the pulling state of the pull rope 301d. At this time, the force of the rotation of the torsion spring will drive the first rotating wheel 301c to rotate, and the pull rope 301d will be reeled up through the rotation of the first rotating wheel 301c, and the rotating rod 201d will be rotated to the initial position through the rotation of the first rotating wheel 301c.

[0035] Example 2

[0036] Reference Figure 1 to Figure 6 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0037] Specifically, a slide groove 201-a is provided on one side of the moving rod 201b, a support plate 202a is provided in the slide groove 201-a, the support plate 202a slides in the slide groove 201-a, and a stopper 202b is fixed at one end of the support plate 202a.

[0038] There are two support plates 202a, both of which slide in the slide groove 201-a. When the moving rod 201b moves, the slide groove 201-a will move on the support plate 202a, so as to support the moving rod 201b and prevent the moving rod 201b from shifting during movement. There are two stoppers 202b, both of which are fixed at one end of the support plate 202a. The setting of the stopper 202b can limit the moving rod 201b to prevent the moving rod 201b from moving excessively and falling off the support plate 202a.

[0039] Specifically, a support block 302a is sleeved on the outer side of the worm 301b, and the support block 302a and the worm 301b are movably connected.

[0040] The support block 302a is used to support the worm 301b to prevent the worm 301b from deviating when rotating.

[0041] Specifically, a protective cover 302b is provided on one side of the worm gear 301a, a pull rope 301d is inserted into the top of the protective cover 302b, the protective cover 302b is movably connected to the pull rope 301d, a connecting column 302c is fixed on one side of the worm gear 301a, and the connecting column 302c is fixed on one side of the rotating rod 201d.

[0042] The protective cover 302b is used to protect the worm wheel 301a to prevent the worm wheel 301a from being hit by foreign objects and causing damage. When the worm wheel 301a rotates, it will drive the connecting column 302c to rotate, and the rotation of the connecting column 302c can drive the rotating rod 201d to rotate.

[0043] Specifically, it also includes an adjustment component 400, which is arranged on one side of the second rotating wheel 301e, including a rotating shaft 401a, a rotating block 401b, a damping block 401c and a spring 401d. The rotating shaft 401a is fixed to one side of the second rotating wheel 301e, the rotating block 401b is fixed to one end of the rotating shaft 401a, the damping block 401c is arranged on one side of the rotating block 401b, and the spring 401d is arranged in the damping block 401c.

[0044] Six protrusions are arranged on one side of the rotating block 401b, and there are six damping blocks 401c, all of which are located on one side of the rotating block 401b. One side of the rotating block 401b is arranged as an inclined surface. When the second rotating wheel 301e rotates, it will drive the rotating shaft 401a to rotate. The rotation of the rotating shaft 401a will drive the rotating block 401b to rotate. The rotation of the rotating block 401b will cause the protrusions on one side to squeeze the damping block 401c. When squeezing the damping block 401c, a squeezing force can be applied to the spring 401d. When the protrusion rotates to separate from the rotating block 401b, the rebound force of the spring 401d can make the damping block 401c return to its original position. In this way, the reciprocating movement can play a damping effect when adjusting the angle of the rearview mirror 102. The damping can provide a certain resistance, so that the driver can control the adjustment amplitude and position more finely and accurately when adjusting the angle of the rearview mirror 102, and avoid over-adjustment or under-adjustment.

[0045] Specifically, a fixing sleeve 402a is sleeved on the outer side of the rotating shaft 401a.

[0046] The fixing sleeve 402a is used to support the rotating shaft 401a to prevent the rotating shaft 401a from deviating when rotating.

[0047] Specifically, a support frame 402b is sleeved on the outer side of the damping block 401c, and the support frame 402b and the damping block 401c are movably connected.

[0048] The support frame 402b is used to support the damping block 401c to prevent the damping block 401c from deflecting.

[0049] Example 3

[0050] Reference Figure 1 to Figure 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0051] Specifically, a protective shell 402c is provided on the outer side of the support frame 402b.

[0052] The protective shell 402c is used to protect the spring 401d to prevent the spring 401d from being hit by foreign objects and being damaged.

[0053] Specifically, a mounting plate 101 is sleeved on the outer side of the rotating shaft 401 a , the mounting plate 101 is movably connected to the rotating shaft 401 a , and the supporting frame 402 b and the protective shell 402 c are both fixed to one side of the mounting plate 101 .

[0054] The mounting plate 101 is used to support the support frame 402b and the protective shell 402c to prevent the two from being offset. The rearview mirror 102 can be installed in the car through the arrangement of the mounting plate 101.

[0055] Specifically, a rearview mirror 102 is fixed to one side of the fixing sleeve 402a.

[0056] The rearview mirror 102 allows the driver to see the traffic conditions behind the vehicle, including other vehicles, pedestrians, bicycles, etc., so as to make timely driving decisions, such as changing lanes, overtaking, slowing down or stopping.

[0057] When in use, when different people drive the same car, due to differences in height, sitting posture and driving habits, they need to adjust the angle of the rearview mirror 102 to obtain the best field of view. When adjusting the angle of the rearview mirror 102, the rotation of the rearview mirror 102 drives the fixed sleeve 402a to rotate, and the rotation of the fixed sleeve 402a drives the rotating shaft 401a to rotate, and the rotation of the rotating shaft 401a drives the rotating block 401b to rotate, and the rotation of the rotating block 401b causes the convex block on one side to squeeze the damping block 401c. When squeezing the damping block 401c, a squeezing force can be applied to the spring 401d. When the convex block rotates to separate from the rotating block 401b, the rebound force of the spring 401d can make the damping block 401c return to its original position. This reciprocating movement can have a damping effect when adjusting the angle of the rearview mirror 102. The damping can provide a certain resistance, so that the driver can control the adjustment amplitude and position more finely and accurately when adjusting the angle of the rearview mirror 102, avoiding over-adjustment or under-adjustment.

[0058] When the rotating shaft 401a rotates, the second rotating wheel 301e will be driven to rotate. The rotation of the second rotating wheel 301e will reel in the pull rope 301d to move the pull rope 301d. The movement of the pull rope 301d can drive the first rotating wheel 301c to rotate. The rotation of the first rotating wheel 301c will drive the worm 301b to rotate. The rotation of the worm 301b can drive the worm wheel 301a to rotate. At this time, the rotation of the worm wheel 301a will drive the connecting column 302c to rotate. The rotation of the connecting column 302c can drive the rotating rod 2 01d rotates, and the rotation of the rotating rod 201d will drive the two hinged rods 201c to move toward each other at the same time. The movement of the hinged rod 201c will drive the moving rod 201b to move, and the movement of the moving rod 201b can drive the backlight 201a to move the backlight 201a to a suitable lighting position. No matter how the rearview mirror is adjusted, the backlight can always accurately illuminate the key area, ensuring that the driver can obtain a clear and bright rear view at any viewing angle, reducing the observation blind spot caused by insufficient light or shadows.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
