The upper surface of the driving disc 301 is provided with an arc-shaped slot 3011, and the bottom wall of the arc-shaped slot 3011 is an inclined plane or an arc surface. The balls 303 are slidably disposed in the arc-shaped slots 3011, and at least a portion of the balls 303 protrudes from the upper end surface of the driving disk 301 and is connected to the lower end surface of the driven disk 302.

It is understood that the driving disk 301 is rotatably provided on the rotation shaft 2, and the driven disk 302 is rotatably provided on the rotation shaft 2. In other words, the central axis of the driving disk 301 is coaxial with the central axis of the rotating shaft 2, and the central axis of the driven disk 302 is coaxial with the central axis of the rotating shaft 2.

Alternatively, as shown in fig. 1 and 2, the driving disk 301 is sleeved on the rotating shaft 2, and the driven disk 302 is sleeved on the rotating shaft 2. The driving disk 301 is located below the driven disk 302, and a gap is provided between the driving disk 301 and the driven disk 302 in the up-down direction. The upper surface of the driving plate 301 is provided with an arc-shaped slot 3011, the path of the arc-shaped slot 3011 is arc-shaped, and the center of the arc-shaped slot 3011 is located on the central axis of the rotating shaft 2. The lower parts of the balls 303 are slidably arranged in the arc-shaped grooves 3011, the upper parts of the balls 303 protrude out of the upper end face of the driving disc 301 and are positioned in the gap, and the upper parts of the balls 303 are connected with the lower end face of the driven disc 302.

During the rotation of the driving disk 301 along the central axis of the rotating shaft 2, the balls 303 slide in the arc-shaped slots 3011. Because the bottom wall of the arc-shaped slot 3011 is an inclined surface or an arc surface, the ball 303 moves upward in the process of sliding in the arc-shaped slot 3011, thereby driving the driven disc 302 to move upward.

Optionally, the bottom wall of arcuate slot 3011 is comprised of two sloped surfaces, the length of the sloped surfaces along the path of arcuate slot 3011 being equal to the length of one-half of the path of arcuate slot 3011. The lower ends of the two inclined planes are both located in the middle of the arc-shaped slot 3011, and the upper ends of the two inclined planes are respectively located at the two ends of the arc-shaped slot 3011 along the path direction of the arc-shaped slot 3011. The ball 303 is located at the middle of the arcuate slot 3011, i.e., at the lower end of the ramp. Therefore, the balls 303 can be moved up while sliding in the arc-shaped slots 3011 regardless of whether the driving disk 301 rotates clockwise or counterclockwise.

In some embodiments, the height difference between the highest point and the lowest point of the bottom wall of the arcuate slot 3011 is greater than or equal to 3 mm.

It can be understood that the height difference between the highest point and the lowest point of the bottom wall of the arc-shaped slot 3011 is greater than or equal to 3mm, so that the driving disk 301 drives the driven disk 302 to move upwards by greater than or equal to 3 mm.

Optionally, the distance between the lower end of the inclined plane and the upper end of the inclined plane in the up-down direction is 3 mm. When the driving disk 301 rotates, the balls 303 slide with respect to the arc-shaped slots 3011. Ball 303 gradually slides from the lowest point of arc-shaped slot 3011 to the highest point of arc-shaped slot 3011, and ball 303 moves upward. After the balls 303 slide to the highest point of the arc-shaped slot 3011, the balls 303 drive the driven disc 302 to ascend by 3mm, so as to drive the vehicle-mounted device 5 to ascend by 3 mm.

In some embodiments, as shown in fig. 2, the arc-shaped slots 3011 and the balls 303 are both multiple, multiple arc-shaped slots 3011 are arranged at intervals along the circumferential direction of the driving disk 301, and the arc-shaped slots 3011 correspond to the balls 303 one by one.

It can be understood that the arc-shaped slots 3011 and the balls 303 are multiple, and the multiple balls 303 support the driven disk 302 together along the circumferential direction of the driven disk 302, so that the stress on the driven disk 302 is uniform, the driven disk 302 is prevented from being inclined, and the abrasion caused by the uneven stress on the inner wall of the driven disk 302 and the circumferential wall of the rotating shaft 2 is avoided.

Alternatively, as shown in fig. 2, the arc-shaped slots 3011 and the balls 303 are three, three arc-shaped slots 3011 are arranged at intervals along the circumferential direction of the driving disk 301, and the three arc-shaped slots 3011 correspond to the three balls 303 one by one.

In some embodiments, as shown in fig. 1 and 2, the upper end surface of the driving disk 301 is further provided with an annular groove 3012, a first protrusion 3013 is provided in the annular groove 3012, the lower end surface of the driven disk 302 is provided with at least two second protrusions 3021, the second protrusions 3021 are slidably fitted in the annular groove 3012, and the first protrusion 3013 is located between the two second protrusions 3021.

Alternatively, as shown in fig. 1 and 2, the central axis of the annular slot 3012 is coaxial with the centerline axis of the driving disk 301, and the radius of the annular slot 3012 is smaller than the radius of the arc-shaped slot 3011. In other words, the annular groove 3012 is located closer to the rotary shaft 2 than the distance between the arc-shaped groove 3011 and the rotary shaft 2. The first protrusion 3013 is disposed in the annular groove 3012 in the up-down direction, and the upper end of the first protrusion 3013 is adjacent to the notch of the annular groove 3012. The lower end surface of the driven disc 302 is provided with two second protrusions 3021, the upper ends of the second protrusions 3021 are connected with the lower end surface of the driven disc 302, and the lower ends of the second protrusions 3021 are slidably fitted in the annular groove 3012. The first protrusion 3013 is located between the two second protrusions 3021, and during clockwise or counterclockwise rotation of the driving disk 301, the first protrusion 3013 will abut against any one of the second protrusions 3021.

Further, there are two first protrusions 3013 and four second protrusions 3021, and one first protrusion 3013 corresponds to two second protrusions 3021. The two first protrusions 3013 are arranged at intervals along the circumferential direction of the driving disk 301.

It can be understood that, when the driving disk 301 rotates forward to lift the driven disk 302, the elastic member 304 compresses to store energy, and the elastic member 304 gives downward elastic force to the driven disk 302. When the driving disk 301 rotates reversely to drive the driven disk 302 to descend, the elastic member 304 releases energy, and the elastic member 304 pushes the driven disk 302 to move downwards. Thereby improving the effectiveness of the falling reset after the vehicle-mounted device 5 is lifted.

Alternatively, as shown in fig. 1, the elastic member 304 is located between the top wall of the housing 1 and the upper end face of the driven disc 302, the upper end of the elastic member 304 abuts against the top wall of the housing 1, and the lower end of the elastic member 304 abuts against the upper end face of the driven disc 302.

It can be understood that the output shaft of the motor 401 drives the reduction gear 402 to rotate, the reduction gear 402 is engaged with the driving disk 301, and the driving disk 301 is driven to rotate during the rotation of the reduction gear 402. Also, the motor 401 is powered by an external power source, for example, the motor 401 is connected to a battery of a vehicle.

Alternatively, as shown in fig. 1, the motor 401 and the reduction gear 402 are located on the rear side of the moving assembly 3. The motor 401 is provided in the housing 1, and the motor 401 is located above the reduction gear 402.

The lower end of the in-vehicle device 5 is bonded to an interior (not shown) on the vehicle instrument panel, thereby providing an integral aesthetic effect.

The motor 401 rotates forward, the reduction gear 402 rotates and drives the driving disk 301 to rotate, and when the driving disk 301 initially rotates, the driven disk 302 moves upward, so that the vehicle-mounted device 5 is driven to move upward. When the balls 303 slide to the highest point of the arc-shaped slot 3011, the first protrusions 3013 abut against the second protrusions 3021, the driving disk 301 rotates and does not drive the driven disk 302 to move upward, and the driving disk 301 drives the driven disk 302 to rotate synchronously, so that the effect of adjusting the angle of the vehicle-mounted device 5 is achieved.

After the angle of the vehicle-mounted device 5 is adjusted to the position that the user can adapt to, the motor 401 rotates reversely, the elastic part 304 releases energy, and the ball 303 gradually slides to the lowest point of the arc-shaped groove 3011, so that the vehicle-mounted device 5 is driven to descend, and the vehicle-mounted device 5 is attached to the instrument desk of the vehicle again.

It can be understood that the purpose of the ascending of the vehicle-mounted device 5 is to meet the requirement of the movement gap between the vehicle-mounted device 5 and the instrument desk, and to avoid the abrasion of the vehicle-mounted device 5 and the instrument desk caused by the mutual friction between the vehicle-mounted device 5 and the instrument desk in the process of adjusting the angle of the vehicle-mounted device 5. After the angle of the vehicle-mounted device 5 is adjusted, the vehicle-mounted device descends and resets, the integral texture of the interior of the vehicle is guaranteed, and therefore the defects in appearance and the waste in space caused by the gap between the vehicle-mounted device 5 and the instrument desk are avoided.

In addition, mobile unit 5 removes and rotates through rotatory elevating gear drive effect down, among the contrast correlation technique, fixed design's mobile unit 5, mobilizable mobile unit 5 can bring the better sense organ of user and experience to effectively promote the ceremony sense of vehicle passenger cabin.
