[0002] The rearview mirror of a car is used to provide the driver with a view of the side and rear of the car, and to provide advance observation for operations such as changing lanes, parking, and opening doors to avoid traffic accidents. However, rear passengers cannot observe the situation behind the side of the car through the rearview mirrors on both sides of the front row of the car. In order to avoid collisions with vehicles or pedestrians from behind, they must turn their bodies sideways to observe, which is inconvenient. Therefore, in the prior art, a rearview mirror dedicated to rear passengers is added to the B-pillar position on the exterior of the car to solve this problem, but the overall appearance of the car is affected; there is also a rearview mirror dedicated to rear passengers added to the B-pillar position inside the car to solve this problem, but the angle of the rearview mirror cannot be adjusted or the angle adjustment is inconvenient, which gives the rear passengers a poor experience. Utility Model Content

[0003] In view of the above-mentioned problems, the purpose of the utility model is to provide a rearview mirror specially designed for rear passengers in a vehicle and a vehicle, so as to prevent the rear passengers from colliding with vehicles or pedestrians coming from behind when getting out of the vehicle and opening the door. At the same time, the lens angle can be adjusted in multiple directions according to actual needs, so as to provide the rear passengers with a good side and rear view of the vehicle and improve the riding experience of the rear passengers.

[0004] The purpose of the utility model is achieved through the following technical solutions:

[0005] Provided is a vehicle-mounted rearview mirror for rear passengers, comprising a lens, an upper base for mounting the lens, and a driving unit for driving the lens to deflect up and down, wherein a driven universal top cap and an active universal top cap are provided on the back of the lens, the upper base is provided with a connecting piece connected to the driven universal top cap ball head, the driving unit comprises a driving piece and a lifting column, the top end of the lifting column is connected to the active universal top cap ball head, and the driving piece can drive the lifting column to rise and fall, so as to drive the lens to deflect in multiple directions.

[0006] This scheme designs a rearview mirror for rear passengers in the vehicle, and realizes flexible deflection of the rearview mirror in multiple directions by designing active universal and driven universal adjustment devices. The driven universal top cap set on the back of the lens is connected to the connecting piece of the upper base in the form of a ball head hinge, which plays a role in connecting and fixing the lens on the one hand, and on the other hand, the lens can be deflected around the connection point; an active universal top cap is set next to the driven universal top cap, and is connected to the top of the lifting column in the form of a ball head hinge. Through the control system, the driving part can be freely controlled to drive the lifting column to rise and fall, and through the connection structure with the driven universal top cap, the lens can be deflected in multiple directions around the connection point of the driven universal top cap, providing a good field of view for the rear passengers to get off the car and view the side and rear of the car, improving safety, and at the same time, the driving part can use a silent DC motor, which has low noise when driving the lens to deflect, and also brings a good experience to the passengers.

[0007] Furthermore, two active universal top caps are provided, and the two active universal top caps and the driven universal top cap are distributed in a triangle.

[0008] Two active universal top caps are set to match two sets of drive units. By controlling the movement and lifting of two lifting columns, the lens can be deflected in four directions: up, down, left, and right. When the two lifting columns are lifted at the same time, the lens can be deflected upward; when the two lifting columns are lowered at the same time, the lens can be deflected downward; when one lifting column is raised and the other is lowered, the lens can be deflected to the left or right. This adjustment method is not only simple, but also highly accurate. Rear passengers can adjust the lens angle according to their needs to observe the side and rear vision of the car to avoid blind spots.

[0009] Furthermore, the driven universal top cap is located at the center of the back side of the lens, and the two active universal top caps are symmetrically arranged on both sides of the driven universal top cap.

[0010] The driven universal top cap is located at the center of the back of the lens, and forms a symmetrical design with the active universal top cap, ensuring the balance and stability of the lens. No matter in which direction, the overall structure can remain balanced, and the lens rotates around the center point during rotation. The lens will not have asymmetric deflection on both sides, providing a better visual experience.

[0011] Furthermore, the upper base is provided with a first cavity, the connecting member is located at the bottom of the first cavity, and the lens is placed in the first cavity.

[0012] A first cavity is set on the upper base, and the lens is placed in the first cavity. When no deflection occurs, the surface of the lens is flush with the end face of the first cavity, and there is a small gap between the edge of the lens and the inner side surface of the first cavity. The connecting piece is hidden inside the first cavity, thereby ensuring the integrity of the rearview mirror.

[0013] Furthermore, it also includes a lower base, the lower base is connected with the upper base to form a second cavity, and the drive unit is installed in the second cavity. A through hole is provided at the bottom of the first cavity corresponding to the active universal top cap, and the lifting column passes through the through hole and is connected to the ball head of the active universal top cap.

[0014] By designing a form of split connection between the lower base and the upper base, a closed second cavity for accommodating the drive unit is separately set up, so that the drive unit is separated from the lens, and dust, water and other impurities are prevented from entering the second cavity from the gap between the lens and the edge of the upper base, so as to protect the drive unit from damage. The drive unit is arranged in the second cavity, and a through hole corresponding to the active universal top cap is opened at the bottom of the first cavity, and the lifting column passes through the through hole to connect with the ball head of the active universal top cap, and there is a small gap between the through hole and the lifting column, so as to ensure the airtightness of the second cavity as much as possible.

[0015] Furthermore, the driving unit also includes a worm connected to the output end of the driving member, and a worm wheel sleeved on the outer periphery of the jacking column and meshing with the worm. The jacking column is threadedly connected to the worm wheel, and the driving member drives the worm wheel to rotate through the worm to drive the jacking column to rise and fall.

[0016] The drive unit adopts a worm gear transmission method, which not only has a compact structure and smooth transmission, reducing the noise generated during the transmission process, but also has self-locking properties, which can ensure that the lens cannot be tampered with or rotated at will, avoiding unnecessary shaking and rotation of the lens due to human intervention or when the car is driving on bumpy roads.

[0017] Furthermore, the lower base is provided with a guide column, the outer periphery of the guide column is provided with a limiting groove, the bottom of the lifting column is provided with a blind hole, the inner surface of the blind hole is provided with a limiting protrusion, the guide column is inserted into the blind hole, and the limiting protrusion is embedded in the limiting groove.

[0018] The jacking column is sleeved on the guide column so that the jacking column does not tilt when it is lifted or lowered through the threaded structure between the jacking column and the worm gear. At the same time, the limiting matching structure between the guide column and the jacking column ensures that the jacking column does not rotate when it is lifted or lowered.

[0019] Furthermore, it also includes a controller, which is electrically connected or signal-connected to the driving unit. The controller can control the driving unit to drive the lens to deflect. The controller can be arranged on the upper base, or separately arranged as an independent module outside the rearview mirror body.

[0020] The rotation of the lens is controlled by a controller, which is electrically or signal-connected to the drive unit. A control button is provided on the controller, and when the lens needs to be rotated, the control button can be pressed. There are many options for the position setting of the controller, which can be set on the upper base or as an independent module separated from the rearview mirror body.

[0021] Furthermore, the controller is a touch screen control module or a voice control module.

[0022] In order to provide passengers with a better user experience, the controller can be designed as a touch screen control module, integrated into the on-board computer, and the deflection of the lens can be controlled by the on-board computer. In addition, it can also be designed as a voice control module, and the passenger can control the deflection of the lens through voice control.

[0023] Furthermore, a car includes a B-pillar, and the guard plate of the B-pillar is embedded with the above-mentioned rear-seat passenger-only rearview mirror.

[0024] The present scheme also designs a car having the above-mentioned rear-seat passenger-only rear-view mirror. The rear-view mirror can be embedded in the guard plate of the B-pillar of the car inside the car and is flush with the guard plate surface, so that the rear-view mirror and the guard plate of the B-pillar of the car are integrated into one, which is more beautiful. When getting off the car, the rear passengers do not need to turn sideways to observe the situation on the side and rear of the car. The controller can be used to adjust the deflection angle of the lens to expand the field of vision, so that the situation on the side and rear of the car can be better observed, giving the passengers a better experience.

[0037] This scheme designs a rearview mirror for rear passengers in a vehicle, and realizes flexible deflection of the rearview mirror in multiple directions by designing active universal and passive universal adjustment devices. The passive universal top cap 11 set on the back of the lens 1 is connected to the connecting piece 21 of the upper base 2 in the form of a ball head hinge, which plays a role in connecting and fixing the lens 1 on the one hand, and on the other hand, the lens 1 can be deflected around the connection point; an active universal top cap 12 is set beside the passive universal top cap 11, and is connected to the top of the lifting column 32 in the form of a ball head hinge. Through the control system, the driving member 31 can be freely controlled to drive the lifting column 32 to rise and fall, and through the connection structure with the passive universal top cap 11, the lens 1 can be deflected in multiple directions around the connection point of the passive universal top cap 11, providing a good field of view for the rear passengers to get off the car and view the side and rear of the car, improving safety, and at the same time, the driving member 31 adopts a silent DC motor, which has low noise when driving the lens 1 to deflect, and also brings a good experience to the passengers.

[0038] like Figure 2 and Figure 3 As shown, the active universal top cap 12 is provided with a spherical groove structure, the end of the lifting column 32 is a spherical structure, and the spherical structure is clamped into the spherical groove by extrusion, or the active universal top cap 12 is a spliced ​​structure of two half top caps, and the spherical structure is clamped into the spherical groove by splicing and combination; the spherical structure can rotate freely in the spherical groove. The connection structure of the driven universal top cap 11 and the connecting member 21 is the same as above.

[0039] like Figure 2 As shown, the driven universal top cap 11 is located at the center of the back of the lens 1, and two active universal top caps 12 are provided. The two active universal top caps 12 are symmetrically arranged on both sides of the driven universal top cap 11, and are distributed in a triangle with the driven universal top cap 11. Two active universal top caps 12 are provided to match two sets of drive units 3. By controlling the movement and lifting of two lifting columns 32, the deflection of the lens 1 in four directions of up, down, left and right can be achieved. When the two lifting columns 32 are lifted at the same time, the lens 1 can be adjusted to deflect upward; when the two lifting columns 32 are lowered at the same time, the lens 1 can be adjusted to deflect downward; when the lifting columns 32 are raised and lowered one by one, the lens 1 can be adjusted to deflect to the left or right. This adjustment method is not only simple, but also highly accurate. The rear passengers can adjust the angle of the lens 1 according to their needs to observe the side and rear field of view of the car to avoid blind spots. The driven universal top cap 11 is located at the center of the back of the lens 1, and forms a symmetrical design with the active universal top cap 12, ensuring the balance and stability of the lens 1. No matter in which direction, the overall structure can be kept balanced, and during the rotation process, the lens 1 rotates around the center point, and the lens 1 will not have asymmetric deflection on both sides of the symmetry, resulting in a better visual perception.

[0040] like Figure 1As shown, the upper base 2 is provided with a first cavity 22, the connecting member 21 is located at the bottom of the first cavity 22, and the lens 1 is placed in the first cavity 22. The first cavity 22 is provided on the upper base 2, and the lens 1 is placed in the first cavity 22. When no deflection occurs, the surface of the lens 1 is flush with the end surface of the first cavity 22, and there is a small gap between the edge of the lens 1 and the inner side surface of the first cavity 22, and the connecting member 21 is hidden inside the first cavity 22, thereby ensuring the integrity of the rearview mirror.

[0041] like Figure 1 and Figure 3 As shown, the rearview mirror also includes a lower base 5, which is connected to the upper base 2 to form a second cavity 53, and the drive unit 3 is installed in the second cavity 53. A through hole 23 is provided at the bottom of the first cavity 22 corresponding to the active universal top cap 12, and the lifting column 32 passes through the through hole 23 and is connected to the ball head of the active universal top cap 12. By designing the form of split connection between the lower base 5 and the upper base 2, a closed second cavity 53 for accommodating the drive unit 3 is separately set up, so that the drive unit 3 is separated from the lens 1, and dust, water and other impurities are prevented from entering the second cavity 53 from the edge gap between the lens 1 and the upper base 2, so as to protect the drive unit 3 from damage. The drive unit 3 is arranged in the second cavity 53, and a through hole 23 corresponding to the active universal top cap 12 is provided at the bottom of the first cavity 22, and the lifting column 32 passes through the through hole 23 and is connected to the ball head of the active universal top cap 12, and there is a small gap between the through hole 23 and the lifting column 32, thereby ensuring the airtightness of the second cavity 53 as much as possible.

[0042] like Figure 3 and Figure 4 As shown, the driving unit 3 also includes a worm 34 connected to the output end of the driving member 31, a worm wheel 33 sleeved on the outer periphery of the lifting column 32 and meshed with the worm 34, the lifting column 32 is threadedly connected to the worm wheel 33, and the driving member 31 drives the worm wheel 33 to rotate through the worm 34 to drive the lifting column 32 to rise and fall.

The lifting column 32 is sleeved on the guide column 51, so that the lifting column 32 will not tilt or shake when it is lifted or lowered through the threaded structure between the lifting column 32 and the worm gear 33. At the same time, the limiting matching structure between the guide column 51 and the lifting column 32 ensures that the lifting column 32 will not rotate when it is lifted or lowered.

After being processed by the MCU, the MCU sends relevant instructions to the drive module. The drive module controls the drive member 31, i.e., the DC motor, to rotate forward or reverse to make the lifting column 32 rise and fall, thereby realizing the deflection of the lens 1.
