Detailed implementation manners

[0026] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present application, the following will further describe the solutions of the present application. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to fully understand the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only part of the embodiments of the present application, rather than all of the embodiments.

[0028] With the improvement of the intelligent level of automobiles, it has become a trend to install in-vehicle screens. The appearance of in-vehicle screens can meet people's needs for information and entertainment, provide integration and convenience, assist vehicle operation and display important information. The in-vehicle screen will be configured with a deflection mechanism to be able to adapt to different viewing angles and line-of-sight requirements, and provide the best viewing effect and operation convenience. The existing deflection mechanisms usually use two motors to control the side-turning action and the forward movement action, which occupy a relatively large space and are not suitable for vehicles with a small gap between the in-vehicle screen and the instrument panel.

[0029] Based on this, an embodiment of the present application provides a side-turning device applicable to the screen body of an in-vehicle screen. When the screen body is connected to the side-turning device for use, the screen body can turn to either side among the two sides, so as to adapt to different viewing angles and line-of-sight requirements. The side-turning device occupies a small space, especially saving a lot of space in the length direction of the vehicle. The side-turning device occupies a small space in the length direction of the vehicle when realizing the side-turning of the screen body, meeting the use requirements of vehicles with a small gap between the in-vehicle screen and the instrument panel.

[0030] The following details the mobile terminal photographing cabinet through specific embodiments:

[0031] Referring to Figures 1 to 3 As shown, this embodiment provides a side-turning device, including a first connecting rod 2, a second connecting rod 3, and a driving gear 4. One end of the first connecting rod 2 is hinged to the screen body 5, the other end of the first connecting rod 2 is meshed with the driving gear 4, one end of the second connecting rod 3 is hinged to the screen body 5, and the other end of the second connecting rod 3 is meshed with the driving gear 4.

[0032] As Figure 1 and Figure 2 shown, when the driving gear 4 rotates clockwise, the second connecting rod 3 pulls one side of the screen body 5 to turn in the clockwise direction. When the driving gear 4 rotates counterclockwise, the first connecting rod 2 pulls the screen body 5 to turn in the counterclockwise direction. That is, by controlling the clockwise or counterclockwise rotation of the driving gear 4, the screen body 5 can be turned to either side among the two sides, so as to adapt to different viewing angles and line-of-sight requirements. The side-turning device occupies a small space in the length direction of the vehicle when realizing the side-turning of the screen body 5, meeting the use requirements of vehicles with a small gap between the in-vehicle screen body 5 and the instrument panel.

[0033] In some embodiments, as Figure 1 and Figure 2 shown, the side-turning device further includes a base 1. The driving gear 4 is rotatably connected to the base 1. A first plate 22 is formed on the first connecting rod 2, and a second plate 32 is formed on the second connecting rod 3. The first plate 22 and the second plate 32 are rotatably connected to the driving gear 4, and the rotation center coincides with the rotation axis of the driving gear 4. That is to say, the rotation center of the first plate 22 rotatably connected to the driving gear 4, the rotation center of the second plate 32 rotatably connected to the driving gear 4, and the rotation axis of the driving gear 4 coincide in the projection on the base 1. The base 1 supports other components of the side-turning device. The first plate 22 and the second plate 32 are rotatably connected to the driving gear 4, so that the first connecting rod 2 and the second connecting rod 3 will not disengage from the driving gear 4 when pulling the screen body 5 to turn, and still maintain the meshed connection state.

[0034] In some embodiments, as Figure 2As shown in the figure, a first hinge seat 6 and a second hinge seat 7 are provided on the back plate of the screen body 5. The first hinge seat 6 is hinged to the first connecting rod 2, and the second hinge seat 7 is hinged to the second connecting rod 3. The first hinge seat 6 and the second hinge seat 7 are spaced apart along the length direction of the back plate. That is to say, the first connecting rod 2 is hinged to one side of the screen body 5, and the second connecting rod 3 is hinged to the other side of the screen body 5. The projection of the driving gear 4 on the back plate is located between the first hinge seat 6 and the second hinge seat 7. That is to say, both sides of the driving gear 4 are meshed and driven with the first connecting rod 2 and the second connecting rod 3 respectively. The extension line of the first connecting rod 2 intersects with the extension line of the second connecting rod 3 on the side of the driving gear 4 away from the screen body 5, so that the rotation range of the screen body 5 is relatively large. When the driving gear 4 rotates clockwise, the second connecting rod 3 pulls one side of the screen body 5 to rotate sidewise in the clockwise direction. When the driving gear 4 rotates counterclockwise, the first connecting rod 2 pulls the screen body 5 to rotate sidewise in the counterclockwise direction.

[0035] In some embodiments, as Figure 2 shown, a first rack section 21 meshed and driven with the driving gear 4 is formed on the first connecting rod 2, and a second rack section 31 meshed and driven with the driving gear 4 is formed on the second connecting rod 3, so as to realize the meshing and driving of both sides of the driving gear 4 with the first connecting rod 2 and the second connecting rod 3 respectively.

[0036] In some embodiments, through holes are provided on both the first plate 22 and the second plate 32. A support shaft 41 is formed on the side of the driving gear 4 away from the base 1. A bearing bush 42 is coaxially sleeved around the support shaft 41 and the bearing bush 42 can rotate relative to the support shaft 41. The bearing bush 42 passes through the through holes on the first plate 22 and the second plate 32 in a clearance fit manner. The first plate 22 and the second plate 32 can rotate relative to the bearing bush 42. The second connecting rod 3 will not break away from the driving gear 4 under the limitation of the second plate 32. When the driving gear 4 rotates clockwise, the second connecting rod 3 pulls one side of the screen body 5 to rotate sidewise in the clockwise direction. Similarly, the first connecting rod 2 will not break away from the driving gear 4 under the limitation of the first plate 22. When the driving gear 4 rotates counterclockwise, the first connecting rod 2 pulls the screen body 5 to rotate sidewise in the counterclockwise direction.

[0037] In some embodiments, a large head is formed at one end of the support shaft 41 away from the driving gear 4, and the cross-sectional area of the large head is larger than the inner diameter of the bearing bush 42. A retaining piece extends radially along the outer wall of the bearing bush 42, and the outer diameter of the retaining piece is larger than the inner diameter of the through holes on the first plate 22 and the second plate 32. The first plate 22 and the second plate 32 can rotate relative to the bearing bush 42 and will not break away from the top end of the bearing bush 42. The retaining piece plays a limiting role on the first plate 22 and the second plate 32.

[0038] In some embodiments, an installation cavity is provided on the base 1, and a driving motor 8 is installed in the installation cavity. The output shaft of the driving motor 8 is drivingly connected to the driving gear 4. The driving motor 8 controls the clockwise / counterclockwise rotation of the driving gear 4.

[0039] In some embodiments, one end of the driving motor 8 close to the driving gear 4 protrudes from the upper surface of the base 1, so that a gap is formed between the driving gear 4 and the base 1, avoiding the contact between the first connecting rod 2 and the second connecting rod 3 and the upper surface of the base 1, thereby reducing the friction between the first connecting rod 2 and the second connecting rod 3 and the base 1 during movement.

[0040] In some embodiments, the axis of the driving gear 4 is parallel to the plane where the screen body 5 is located. This makes the occupied space of the side-turning device between the instrument panel and the screen body 5 the smallest.

[0041] Another embodiment of the present application provides a vehicle-mounted screen, including the above-mentioned side-turning device and the screen body. The back plate of the screen body of the vehicle-mounted screen is hinged to the first connecting rod 2 and the second connecting rod 3. When the driving gear 4 rotates clockwise, the second connecting rod 3 pulls one side of the screen body 5 to turn sideward in the clockwise direction. When the driving gear 4 rotates counterclockwise, the first connecting rod 2 pulls the screen body 5 to turn sideward in the counterclockwise direction. That is, by controlling the clockwise or counterclockwise rotation of the driving gear 4, the screen body 5 can be turned sideward to either side, so as to adapt to different viewing angles and line-of-sight requirements.

[0042] Another embodiment of the present application provides a vehicle, including the above-mentioned vehicle-mounted screen. When the vehicle-mounted screen is turned sideward, the occupied space is small, which can meet the needs of more vehicle models.
