The embodiment of the invention provides a turnover mechanism of a notebook computer camera, which is particularly suitable for a turnover camera on a notebook computer; of course, it can also be used for other electronic devices that need to turn the camera, such as mobile phones, tablet computers, desktop computers, or PDAs.
Specifically, as shown in fig. 1 to 6, the turnover mechanism of the notebook computer camera provided in the embodiment of the present invention includes a camera base 100, a first connecting sleeve 210, a second connecting sleeve 220, a third connecting sleeve 230, and a connecting shaft 240.
The camera base 100 is used for installing a camera, and the camera base 100 is generally embedded above a screen of a notebook computer.
The first connecting sleeve 210 is fixedly connected to the camera base 100, and the first connecting sleeve 210 is rotatably disposed on the notebook computer housing 110. The second connecting sleeve 220 and the first connecting sleeve 210 are coaxially arranged, the second connecting sleeve 220 is arranged in the first connecting sleeve 210, and the second connecting sleeve 220 and the first connecting sleeve 210 can rotate in a unidirectional manner. The third connecting sleeve 230 and the first connecting sleeve 210 are coaxially arranged, friction transmission is carried out between the end face of the third connecting sleeve 230 and the end face of the first connecting sleeve 210 by friction force which does not exceed a first preset value, and the first preset value is 1.5-2 times of the gravity of the whole turnover mechanism in general; the third connecting sleeve 230 is rotatably disposed on the notebook computer housing 110, and a first elastic member 231 is disposed between the third connecting sleeve 230 and the notebook computer housing 110, where the first elastic member 231 limits the third connecting sleeve 230 to rotate along its own axis. The camera base 100 is connected with the notebook computer housing 110 through three connecting sleeves, and the camera base 100 can rotate relative to the notebook computer housing 110.
The connecting shaft 240, the connecting shaft 240 is worn on the first connecting sleeve 210; the connecting shaft 240 is in transmission connection with the second connecting sleeve 220, and the second connecting sleeve 220 and the connecting shaft 240 relatively rotate to drive the connecting shaft 240 to axially move along the connecting shaft; when the rotation angle of the third connecting sleeve 230 is smaller than the first angle, the connecting shaft 240 and the third connecting sleeve 230 rotate synchronously, and when the rotation angle of the third connecting sleeve 230 is larger than or equal to the first angle, the connecting shaft 240 and the third connecting sleeve 230 can rotate relatively.
For convenience of description, in this embodiment, the first preset value is 3N, and the first angle is 3 ° is illustrated as an example. When the turnover mechanism of the notebook computer camera provided by the embodiment of the invention is not worn due to use, the turnover process of the camera is as follows:
applying torque to the camera base 100 manually or otherwise by a notebook computer user such that the camera base 100 rotates in a forward direction; the camera base 100 rotates forward, and drives the first connection sleeve 210 to rotate forward synchronously. On the other hand, the first connecting sleeve 210 rotates forward, which drives the second connecting sleeve 220 to rotate forward synchronously, and the second connecting sleeve 220 rotates forward, which drives the connecting shaft 240 to rotate forward synchronously. On the other hand, the first connecting sleeve 210 rotates forward, the third connecting sleeve 230 is driven to rotate forward by friction force, when the rotation angle of the third connecting sleeve 230 is smaller than the first angle, the deformation amount of the first elastic piece 231 is smaller, the elastic force of the first elastic piece 231 is smaller than the friction force between the end face of the third connecting sleeve 230 and the end face of the first connecting sleeve 210, the first connecting sleeve 210 and the third connecting sleeve 230 rotate forward synchronously, and the third connecting sleeve 230 rotates forward to drive the connecting shaft 240 to rotate forward synchronously; in this process, the first connecting sleeve 210, the second connecting sleeve 220, the third connecting sleeve 230 and the connecting shaft 240 are all rotated synchronously. When the rotation angle of the third connecting sleeve 230 is greater than or equal to the first angle, the deformation amount of the first elastic member 231 is greater, the elastic force of the first elastic member 231 is greater than or equal to the friction force between the end surface of the third connecting sleeve 230 and the end surface of the first connecting sleeve 210, the third connecting sleeve 230 is kept stationary relative to the notebook computer casing 110, and the first connecting sleeve 210 and the third connecting sleeve 230 relatively rotate; at this time, the first connecting sleeve 210, the second connecting sleeve 220 and the connecting shaft 240 are rotated synchronously, and the third connecting sleeve 230 is stationary relatively. When the camera base 100 is rotated in place, the camera base 100 is kept stable by means of friction between the first connection sleeve 210 and the third connection sleeve 230. It can be appreciated that when the third connecting sleeve 230 is rotated to the first angle, the elastic force of the first elastic member 231 is exactly equal to the first preset value.
When the turnover mechanism of the notebook computer camera provided in the embodiment of the invention is worn due to use, so that the friction between the first connecting sleeve 210 and the third connecting sleeve 230 is reduced to 2N, the turnover process of the camera is as follows:
applying torque to the camera base 100 manually or otherwise by a notebook computer user such that the camera base 100 rotates in a forward direction; the camera base 100 rotates forward, and drives the first connection sleeve 210 to rotate forward synchronously. On the other hand, the first connecting sleeve 210 rotates forward, which drives the second connecting sleeve 220 to rotate forward synchronously, and the second connecting sleeve 220 rotates forward, which drives the connecting shaft 240 to rotate forward synchronously. On the other hand, the first connecting sleeve 210 rotates forward, the third connecting sleeve 230 is driven to rotate forward by friction force, when the rotation angle of the third connecting sleeve 230 is smaller, the deformation amount of the first elastic piece 231 is smaller, the elastic force of the first elastic piece 231 is smaller than the friction force between the end face of the third connecting sleeve 230 and the end face of the first connecting sleeve 210, the first connecting sleeve 210 and the third connecting sleeve 230 rotate forward synchronously, and the third connecting sleeve 230 rotates forward to drive the connecting shaft 240 to rotate forward synchronously; in this process, the first connecting sleeve 210, the second connecting sleeve 220, the third connecting sleeve 230 and the connecting shaft 240 are all rotated synchronously.
When the rotation angle of the third connecting sleeve 230 is larger but still smaller than the first angle, the elastic force of the first elastic member 231 reaches 2N, the third connecting sleeve 230 is kept stationary relative to the notebook computer housing 110, and the first connecting sleeve 210 and the third connecting sleeve 230 rotate relatively. At this time, since the rotation angle of the third connecting sleeve 230 is smaller than the first angle, the connecting shaft 240 and the third connecting sleeve 230 are circumferentially synchronous, that is, the connecting shaft 240 and the first connecting sleeve 210 and the second connecting sleeve 220 are relatively rotated, and since the connecting shaft 240 and the second connecting sleeve 220 are relatively rotated, the connecting shaft 240 is driven to axially move, the connecting shaft 240 axially moves, and the third connecting sleeve 230 is synchronously driven to axially move, and the third connecting sleeve 230 axially moves, so that the contact force between the third connecting sleeve 230 and the first connecting sleeve 210 is increased, that is, the friction force between the end face of the third connecting sleeve 230 and the end face of the first connecting sleeve 210 is increased, and the connecting shaft 240 axially moves until the friction force between the end face of the third connecting sleeve 230 and the end face of the first connecting sleeve 210 is restored to 3N. In this process, as the friction between the end surface of the third connecting sleeve 230 and the end surface of the first connecting sleeve 210 increases, the rotation angle of the third connecting sleeve 230 increases gradually until it rotates to the first angle.
When the rotation angle of the third connecting sleeve 230 is greater than or equal to the first angle, the deformation amount of the first elastic member 231 is greater, the elastic force of the first elastic member 231 is greater than or equal to the friction force between the end surface of the third connecting sleeve 230 and the end surface of the first connecting sleeve 210, the third connecting sleeve 230 is kept stationary relative to the notebook computer casing 110, and the first connecting sleeve 210 and the third connecting sleeve 230 relatively rotate; at this time, the first connecting sleeve 210, the second connecting sleeve 220 and the connecting shaft 240 are rotated synchronously, and the third connecting sleeve 230 is stationary relatively. When the camera base 100 is rotated in place, the camera base 100 is kept stable by means of friction between the first connection sleeve 210 and the third connection sleeve 230.
Therefore, in the turnover mechanism of the notebook computer camera provided by the embodiment of the invention, when the turnover mechanism of the notebook computer camera is worn due to use, the first connecting sleeve 210, the second connecting sleeve 220, the third connecting sleeve 230 and the connecting shaft 240 are arranged, so that the friction between the notebook computer camera and the notebook computer shell 110 can be adaptively adjusted while the notebook computer camera is turned, and the notebook computer camera can stay at any position and is not influenced by use wear.
In one embodiment, in order to realize that the connecting shaft 240 and the third connecting sleeve 230 rotate synchronously when the rotation angle of the third connecting sleeve 230 is smaller than the first angle, the connecting shaft 240 and the third connecting sleeve 230 can rotate relatively when the rotation angle of the third connecting sleeve 230 is larger than or equal to the first angle, the pushing rod 233 is arranged in the third connecting sleeve 230 in a penetrating manner, the notebook computer shell 110 is provided with a pushing inclined plane 234, one end of the pushing rod 233 is abutted against the end face of the connecting shaft 240, and the other end is abutted against the pushing inclined plane 234. In the initial state, one end of the push rod 233 is abutted against one end of the push inclined plane 234, which is closer to the connecting shaft 240, and at this time, the push inclined plane 234 applies a larger force to the push rod 233, so that the contact force between the push rod 233 and the connecting shaft 240 is larger, and the push rod 233 and the connecting shaft 240 rotate synchronously, so that the third connecting sleeve 230 and the connecting shaft 240 rotate synchronously. When the third connecting sleeve 230 rotates by a certain angle, one end of the push rod 233 abuts against one end of the push inclined surface 234 further away from the connecting shaft 240, and at this time, the push inclined surface 234 applies a smaller force to the push rod 233, so that the contact force between the push rod 233 and the connecting shaft 240 is smaller, the two can rotate relatively, and further the third connecting sleeve 230 and the connecting shaft 240 can rotate relatively.
In one embodiment, in order to make the push rod 233 always abut against the pushing inclined surface 234, the push rod 233 is provided with a second elastic member 232, and the elastic force of the second elastic member 232 always makes the push rod 233 move away from the connecting shaft 240 or have a tendency to move away from the connecting shaft 240.
In one embodiment, transmission threads are disposed on the outer peripheral wall surface of the connecting shaft 240 and the inner peripheral wall surface of the second connecting sleeve 220, and the second connecting sleeve 220 and the connecting shaft 240 rotate relatively to drive the connecting shaft 240 to move axially along the connecting shaft through the transmission threads.
In one embodiment, to achieve unidirectional transmission of the first and second connection sleeves 210 and 220, a unidirectional bearing 211 is provided between the first and second connection sleeves 210 and 220. It is understood that other common unidirectional transmission structures may be used in the present invention, such as providing ratchet teeth and ratchet teeth rings at the connection of the first connection sleeve 210 and the second connection sleeve 220.
In one embodiment, the first elastic member 231 is a coil spring, one end of which is connected to the notebook computer case 110, and the other end of which is connected to the third connecting sleeve 230.
In one embodiment, in order to make the coil spring work better when the third connecting sleeve 230 moves axially, the connecting sleeve further comprises a connecting ring 235, the connecting ring 235 is sleeved on the third connecting sleeve 230, the connecting ring 235 can move axially relative to the third connecting sleeve 230, and the connecting ring 235 and the third connecting sleeve 230 rotate synchronously; one end of the coil spring is connected to the notebook computer case 110, and the other end is connected to the connection ring 235. It should be noted that, since the moving distance of the third connecting sleeve 230 in the axial direction is small, the coil spring can normally operate even if the connecting ring 235 is not provided.
In one embodiment, the camera comprises a magnetic component, and the magnetic component enables the camera base 100 to rotate to an initial position when the notebook computer screen is closed, so that the camera is prevented from being in an improper position when the notebook computer screen is closed, and the camera is prevented from being damaged.

When the notebook computer screen is closed, the distance between the first magnetic member 251 and the second magnetic member 252 is gradually reduced to enable the first magnetic member 251 and the second magnetic member to attract each other, and the camera base 100 is driven to rotate, so that the camera base 100 is rotated to an initial position.
In one embodiment, the magnetic assembly further includes a third magnetic member 253, the third magnetic member 253 is disposed on the camera head base 100, and the third magnetic member 253 and the first magnetic member 251 have the same magnetic property. When the notebook computer screen is closed, the distance between the first magnetic member 251 and the third magnetic member 253 is gradually reduced to the extent that the first magnetic member 251 and the third magnetic member 253 can repel each other and drive the camera base 100 to rotate, and then the distance between the first magnetic member 251 and the second magnetic member 252 is gradually reduced to the extent that the first magnetic member 251 and the second magnetic member can attract each other and further drive the camera base 100 to rotate, so that the camera base 100 is rotated to the initial position.
