As mentioned in the background art, when the existing terminal with a flip camera is subject to a large bump or impact, there is a problem that the driving mechanism is prone to gear slipping, which causes the driving mechanism to fail to drive the flip camera module to flip. The inventor found that The reason for this problem is: as shown in Figures 1A-1C, in the existing terminal with a flip camera, the driving mechanism includes an output shaft and a motor. The flip camera module 15 is connected to one end of the output shaft, and the other end of the output shaft is connected to The motors are often connected by gears, the motor drives the output shaft to rotate, and the rotation of the output shaft drives the flip camera module to rotate, but the flip camera module 15 falls or is bumped when it is opened or on the way, turning the camera The impact force is directly transmitted to the output shaft. When the output shaft receives the impact force, it is easy to cause the gear slip between the output shaft and the motor or the motor to be damaged, and ultimately cause the drive flip function to fail, that is, there is a high risk of damage to the drive components.

Therefore, in order to solve the above problem, in this embodiment, the specific terminal is a mobile phone as an example, as shown in Figs. 2A-6, specifically, the terminal provided in this embodiment includes a terminal body 10, which is set in the terminal body 10. The drive assembly 40 is provided on the back 12 of the terminal body 10 and a reversible turning mechanism 20. Specifically, the terminal body 10 includes a front and a back 12, the display surface is located on the front of the terminal body 10, and the drive assembly 40 is used to drive the turning mechanism 20 is turned over. In this embodiment, when the turning mechanism 20 is turned over, as shown in FIGS. 2B and 2C, the turning mechanism 20 can specifically be turned up 180° from the back 12 of the terminal body 10, from the display surface of the terminal body 10. The turning mechanism 20 can be seen. In this embodiment, the turning mechanism 20 is provided with at least a first camera 21, that is, the turning mechanism 20 may be provided with a first camera 21, or the turning mechanism 20 may be provided with a first camera 21 and Other devices, such as flashlights or distance sensors, etc. In this embodiment, the first camera 21 can be flipped from the back 12 of the terminal body 10 to the display surface 11 of the terminal body 10 along with the flip mechanism 20, but it is flipped as shown in FIG. 2B As shown, at this time, the first camera 21 can be used as a front camera for shooting. After the photo is taken, the driving mechanism drives the turning mechanism 20 to reverse rotation, and the first camera 21 turns to the back 12 of the terminal body 10 along with the turning mechanism 20 ( As shown in Figure 2D), the first camera 21 can be used as a rear camera for shooting at this time. Therefore, in this embodiment, the first camera 21 is provided on the turning mechanism 20, and the turning mechanism 20 is located on the back of the terminal body 10. 12. In this way, when the first camera 21 is used as a front camera, the first camera 21 does not occupy the space on the front of the terminal body 10, so that the front of the terminal body 10 can effectively increase the screen-to-body ratio and realize a true full screen. One camera 21 can be used as a front camera or as a rear camera. Compared with the simultaneous setting of a front camera and a rear camera in the terminal, the number of camera settings is saved, and in this embodiment, it can be used when needed. In the front camera function, the flip mechanism 20 automatically flips a certain angle from the back 12 of the terminal body 10, so that the rear camera can be used in the front, which improves the effect of front camera and enhances the user experience.

Wherein, in this embodiment, the number of first cameras 21 provided on the turning mechanism 20 may be one or multiple. In this embodiment, the number of first cameras 21 provided on the turning mechanism 20 includes, but is not limited to, as shown in the figure. The one shown in 2D.

In this embodiment, the turning direction of the turning mechanism 20 can be turned upward as shown in FIG. 2C, so that when the first camera 21 is used as a front camera, the first camera 21 is located at the top of the terminal body 10, or, in this embodiment , The turning mechanism 20 can also be turned left (as shown in FIG. 2E), right or downward, so that when the first camera 21 is used as a front camera, the first camera 21 can be located on the front of the terminal body 10 (that is, the display surface 11) The left, right (as shown in FIG. 2F) or the bottom end, therefore, in this embodiment, the turning direction of the turning mechanism 20 includes but not limited to the upward turning as shown in FIG. 2C. At the same time, in this embodiment, the turning mechanism When 20 is located on the back 12 of the terminal body 10, the turning mechanism 20 may be located in the middle of the top end of the back 12 of the terminal body 10 as shown in FIG. 2D, or may be located at the upper left end of the back 12 of the terminal body 10 (as shown in FIG. 2E) or Upper right.

Wherein, in this embodiment, the drive assembly 40 includes a drive motor 42 and an output shaft 41 with one end connected to the turning mechanism 20. Specifically, one end of the output shaft 41 is fixedly connected to the turning mechanism 20, and the output shaft 41 is driven by the drive motor 42. Turning downward, the rotation of the output shaft 41 drives the turning mechanism 20 to turn, that is, in this embodiment, the drive assembly 40 realizes the automatic turning of the turning mechanism 20, where, in this embodiment, the turning mechanism 20 can be in the range of 0-180° Rotate arbitrarily within the range. For example, in this embodiment, the turning mechanism 20 can be turned by 90°. At this time, the turning mechanism 20 is perpendicular to the back 12 of the terminal body 10. At this time, the first camera 21 is in a horizontal position. It is placed vertically, and the first camera 21 can take pictures of the scene above it, which achieves the purpose of taking pictures in different directions without moving the terminal position, and avoids the need to adjust the terminal position to take pictures in different directions in the prior art. problem.

Among them, in this embodiment, it further includes: a buffer transmission mechanism 50, the first end 51 of the buffer transmission mechanism 50 is connected to the other end of the output shaft 41, the second end 52 of the buffer transmission mechanism 50 is connected to the drive motor 42, and when When the output shaft 41 receives an impact force, the other end of the output shaft 41 and the first end 51 of the buffer transmission mechanism 50 can rotate, so that the impact force on the output shaft 41 is at the first end 51 of the buffer transmission mechanism 50. Specifically, when the other end of the output shaft 41 is connected to the first end 51 of the buffer transmission mechanism 50, there is friction between the output shaft 41 and the buffer transmission mechanism 50, which can normally drive the turning mechanism 20 to turn over. When the turnover mechanism 20 receives an external impact, the external impact force is transmitted to the output shaft 41. When the output shaft 41 receives an impact force, specifically, when the impact force is greater than the maximum friction force between the output shaft 41 and the buffer transmission mechanism 50, At this time, the other end of the output shaft 41 can rotate with the first end 51 of the buffer transmission mechanism 50. Specifically, the output shaft 41 rotates under the impact force, but the first end 51 of the buffer transmission mechanism 50 does not rotate. In this way, the impact force is disconnected at the first end 51 of the buffer transmission mechanism 50, that is, the buffer transmission mechanism 50 disconnects the transmission of the external impact and releases the external impact force, so that the drive motor 42 is not affected by the external impact and has a positive effect on the drive motor 42 Effective protection. Compared with the prior art, in this embodiment, the buffer transmission mechanism 50 avoids the problem of gear slip or damage to the drive motor 42 due to external impact between the output shaft 41 and the drive motor 42.

Among them, when shooting with the terminal provided in this embodiment, specifically, when a self-timer is required, the driving motor 42 is activated to transmit the output power to the second end 52 of the buffer transmission mechanism 50, and the buffer transmission mechanism 50 drives the output shaft 41 to rotate , The rotation of the output shaft 41 drives the turning mechanism 20 to turn, so that the first camera 21 rotates toward the display surface 11 of the terminal body 10. When the turning mechanism 20 reaches a preset position, the turning mechanism 20 stops turning, and the driving motor 42 stops turning. At this time, the first camera 21 is used as a front camera for shooting. After the shooting, the drive motor 42 rotates. At this time, the drive shaft 421 of the drive motor 42 rotates in the reverse direction to transmit the output power to the buffer transmission mechanism 50. The output shaft 41 is driven to rotate in the reverse direction, and the output shaft 41 drives the turning mechanism 20 to rotate in the reverse direction, and finally rotates to the back 12 of the terminal body 10. When the first camera 21 is located on the back 12 of the terminal body 10, the first camera 21 can It can be used as a rear camera for users to take pictures. In this embodiment, when the turning mechanism 20 is in an open state or is rotating, if the turning mechanism 20 is greatly expanded or impacted at this time, the external impact force is transmitted to the output The shaft 41, the output shaft 41 rotates in the reverse or forward direction under the external impact force, and the rotation of the output shaft 41 causes the external impact force to be disconnected at the first end 51 of the buffer transmission mechanism 50, and the external impact force is released. Therefore, it is avoided that the impact force is transmitted to the driving motor 42 and causing damage to the driving motor 42.

Therefore, the terminal provided by this embodiment includes a terminal body 10, a drive assembly 40 provided in the terminal body 10, and a reversible turning mechanism 20 provided on the back 12 of the terminal body 10, and the turning mechanism 20 is provided with at least The first camera 21, wherein the drive assembly 40 includes a drive motor 42 and an output shaft 41 connected at one end to the turning mechanism 20, and further includes: a buffer transmission mechanism 50, the first end 51 of the buffer transmission mechanism 50 and the other of the output shaft 41 One end is connected, the second end 52 of the buffer transmission mechanism 50 is connected to the drive motor 42, and when the output shaft 41 receives an impact force, the other end of the output shaft 41 and the first end 51 of the buffer transmission mechanism 50 rotate to The impact force on the output shaft 41 is disconnected at the first end 51 of the buffered transmission mechanism 50, so that when the turnover mechanism 20 receives an external impact such as an impact or a collision, the external impact force is transmitted to the output shaft 41, and the output shaft 41 Under the impact force, it can rotate with the first end 51 of the buffer transmission mechanism 50, so that the impact force is disconnected at the first end 51 of the buffer transmission mechanism 50, that is, the buffer transmission mechanism 50 disconnects the external impact transmission and The external impact force is released, so that the driving motor 42 is not affected by the external impact, and the driving motor 42 is effectively protected. Compared with the prior art, in this embodiment, the buffer transmission mechanism 50 avoids the problem of gear slip or damage to the drive motor 42 due to external impact between the output shaft 41 and the drive motor 42.
