Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present utility model, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The following describes in detail the image capturing module overturning device and the electronic device provided by the embodiment of the present utility model through specific embodiments and application scenarios thereof with reference to fig. 1 to 7.

The image pickup module overturning device provided by the utility model, as shown in fig. 1, comprises: mount pad 1, module 2, tilting mechanism 3 and locating part 4 make a video recording.

A groove 111 is formed on one side of the mounting seat 1; the turnover mechanism 3 is arranged on the mounting seat 1.

The turnover mechanism 3 is connected with the camera module 2, and the turnover mechanism 3 is used for driving the camera module 2 to turn between a first position and a second position relative to the mounting seat 1; the camera module 2 is configured such that the flip speed at the second position is smaller than the flip speed at the first position.

In the case that the camera module 2 is at the first position, the camera module 2 is received in the groove 111, and the limiting member 4 is connected with the camera module 2.

In the case that the camera module 2 is at the second position, at least part of the camera module 2 is exposed out of the groove 111, and the limiting member 4 is separated from the camera module 2.

It can be understood that the camera module 2 can be turned over relative to the mounting seat 1, so as to scan or photograph the medium to be scanned in the front and rear directions of the mounting seat 1.

In the second position of the camera module 2, the camera module 2 is turned over relative to the mounting base 1. A certain included angle is formed between one side surface of the camera module 2, which is close to the bottom of the groove 111, and the included angle between the camera module 2 and the bottom of the groove varies within the range of 0-180 degrees.

It should be noted that, when the camera module 2 is at the second position, at least a portion of the camera module 2 is always accommodated in the groove 111, so as to ensure connection between the camera module 2 and the mounting seat 1.

When the camera shooting module 2 is in the second position, the camera shooting module 2 turns upwards by 180 degrees around an axis parallel to the length direction of the mounting seat 1, and the camera shooting module 2 can be used as a front camera of the mounting seat 1 to scan a medium to be scanned, which is positioned in the front direction of the mounting seat 1.

As shown in fig. 2, when the camera module 2 is fully accommodated in the groove 111, that is, when an angle between a side surface of the camera module 2, which is close to the bottom of the groove 111, and the bottom of the groove 111 is 0 °, the camera module 2 is at the first position.

As shown in fig. 2, when the camera module 2 is in the first position, the camera module 2 can be used as a rear camera of the mounting base 1 to scan a medium to be scanned located in the rear direction of the mounting base 1.

The turnover mechanism 3 is arranged on the back surface of the mounting seat 1 and is positioned beside the groove 111. The turnover mechanism 3 is rotatably connected with the camera module 2. Specifically, the tilting mechanism 3 includes a driving motor 31 and a rotating shaft 32. The rotation shaft 32 is connected to an output end of the driving motor 31 so that the driving motor 31 drives the rotation shaft 32 to turn over.

A connecting hole is formed in one side edge of the camera shooting module 2, which is close to the top of the mounting seat 1. The rotating shaft 32 penetrates through the connecting hole to drive the camera module 2 to turn over relative to the mounting seat 1.

It will be appreciated that the rotational speed of the drive motor 31 is the same as the rotational speed of the camera module 2. The camera module 2 has a higher turnover rotating speed in the use process so as to quickly identify the medium to be scanned. In the process of switching the camera module from the first position to the second position, the movement speed of the camera module is high so as to collide with the mounting seat, and the camera module is easy to damage.

According to the camera module overturning device provided by the utility model, the overturning speed of the overturning mechanism 3 is controlled based on the position information of the camera module 2 relative to the groove 111, so that the overturning speed of the camera module 2 is controlled, and the situation that the camera module 2 impacts the mounting seat due to overlarge overturning speed is avoided, and therefore physical protection is realized on the camera module 2.

Specifically, during normal operation, the image capturing module 2 has a turnover speed of a first rotation speed. After the use of the camera is finished, the camera is turned over and returned to the groove 111. During the homing process of the camera module 2, that is, when the camera module 2 is close to being attached to the groove 111, the overturning speed of the driving motor 31 is reduced to the second rotating speed. The second rotation speed is smaller than the first rotation speed, so that the camera module 2 is prevented from impacting the mounting seat due to the fact that the overturning speed of the camera module is too high.

Further, as shown in fig. 1, the present utility model adds the limiting member 4 between the camera module 2 and the mounting base 1, so as to ensure that the camera module 2 is stably stored in the groove 111 and also ensure that the camera module 2 is normally turned.

Wherein, the limiting piece 4 is disconnected with the camera module 2 in the process of overturning the camera module 2, and at the moment, the limiting piece 4 does not participate in work and does not limit the movement of the camera module 2; when the camera module 2 is stored in the groove 111 after being used, the limiting piece 4 is connected with the camera module 2, so that the movement of the camera module 2 is limited, the camera module 2 can be stably contained in the groove 111, and the camera module 2 is prevented from falling off from the groove 111. It should be noted that, in the process of switching the camera module 2 from the second position to the first position, that is, when the camera module 2 approaches to the bottom of the groove 111, the limiting member 4 does not generate an acting force on the camera module 2.

Alternatively, the limiting member 4 may be an electromagnet assembly, and the engaging or disengaging of the electromagnet assembly is controlled based on the positional information of the camera module 2 relative to the recess 111. When the camera module 2 is accommodated in the groove 111, the camera module 2 is firmly fixed in the groove 111 through the attraction of the electromagnet assembly; when the camera module 2 is turned over relative to the groove 111, the electromagnet assembly is disconnected, so that the turning movement of the camera module 2 is not blocked; especially when the camera module 2 is turned over and reset and approaches to the first position, the electromagnet assembly is controlled to be in a separated state, and the electromagnet assembly does not generate acting force on the camera module 2, so that the impact of the camera module 2 on the mounting seat 1 is not aggravated, and the camera module 2 is further protected.

Still alternatively, the limiting member 4 comprises an electrical clamping member. The electric clamping piece comprises a first clamping arm and a second clamping arm. Specifically, a first through hole and a second through hole are respectively formed on the groove walls on two opposite sides of the groove 111, wherein the apertures of the first through hole and the second through hole are respectively larger than the diameters of the first clamping arm and the second clamping arm. The first clamping arm and the second clamping arm are in one-to-one correspondence with the first through hole and the second through hole, and can respectively shuttle in the first through hole and the second through hole Kong Laihui. When the camera module 2 is at the first position, the first clamping arm and the second clamping arm are controlled to extend into the groove 111 so as to clamp the camera module 2, thereby firmly fixing the camera module 2 in the groove 111 and preventing the camera module 2 from loosening; when the camera module 2 is at the second position, the first clamping arm and the second clamping arm are controlled to retract towards the inside of the mounting seat, and the first clamping arm and the second clamping arm are separated from the camera module 2, so that the camera module 2 can be normally turned over.

According to the camera module overturning device provided by the utility model, the groove 111 is formed in the outer wall of the mounting seat 1, so that a rotatable space is provided for overturning the camera module 2, and the camera module 2 can be conveniently stored after being used; the turnover mechanism 3 is connected with the camera module 2, the turnover mechanism 3 is used for driving the camera module 2 to turn between a first position and a second position relative to the mounting seat 1, the turnover speed of the camera module 2 at the second position is smaller than that at the first position, the turnover speed of the turnover mechanism 3 is changed based on the position information of the camera module 2 relative to the groove 111, and when the camera module 2 is reset to be close to the first position, the turnover mechanism 3 can run at a reduced speed so as to reduce the impact force of the camera module 2 on the mounting seat 1 and realize physical protection of the camera module 2; meanwhile, under the condition that the camera module 2 is at the first position, the camera module 2 is firmly fixed on the groove wall of the groove 111 by virtue of the limiting piece 4, and the movement of the camera module 2 in the groove 111 is limited, so that the camera module 2 can be firmly accommodated in the groove 111; under the condition that the camera shooting module 2 is located at the second position, the limiting piece 4 is separated from the camera shooting module 2, the limiting piece 4 does not generate acting force on the camera shooting module 2, and the camera shooting module 2 can be guaranteed to normally overturn.

In some embodiments, as shown in fig. 1, the camera module flipping device includes a detection assembly 5. The detection component 5 is used for detecting the position information of the camera module 2 which is overturned relative to the mounting seat 1.

The detection unit 5 is used for being connected with a control board 1001 on the electronic device, and the control board 1001 is connected with the tilting mechanism 3.

The control board 1001 is used for controlling the turnover mechanism 3 to drive the camera module 2 to turn over according to the position information.

It is understood that the control board 1001 may be a printed circuit board (Printed circuit boards, PCB) as known in the art. The control board 1001 is mounted inside the electronic apparatus.

The detecting assembly 5 includes a first detecting member and a second detecting member. The first detection part is located in the mounting seat 1, and the second detection part is located in the camera module 2. The first detecting piece is matched with the second detecting piece. The first detecting piece and the second detecting piece are matched with each other to detect the position information of the camera module 2 relative to the mounting seat 1.

The control board 1001 is electrically connected to the detection unit 5 and the tilting mechanism 3, respectively. The detection unit 5 transmits the detected positional information of the camera module 2 with respect to the mount 1 to the control board 1001, and the control board 1001 can control the rotation speed of the tilting mechanism 3 based on the positional information.

Specifically, the turning mechanism 3 has a first rotational speed and a second rotational speed, wherein the first rotational speed is greater than the second rotational speed. When the detection assembly 5 detects that a larger angle is formed between the camera module 2 and the bottom of the groove 111, at this time, the camera module 2 is in a normal working state, and the control board 1001 controls the driving motor 31 to operate at a first rotation speed according to the angle information, so that the rotation shaft 32 drives the camera module 2 to operate at the first rotation speed; in the process of turning and homing the camera module 2 to the groove 111, when the detection assembly 5 detects that a smaller angle is formed between the camera module 2 and the bottom of the groove 111, the control board 1001 controls the rotation speed of the driving motor 31 to be the second rotation speed, and then the rotation shaft 32 drives the camera module 2 to run at a speed reduction.

In an alternative embodiment, the control board 1001 controls the turning speed of the driving motor 31 to be reduced to the second rotation speed when the detecting component 5 detects that the detecting component is 15 ° with the bottom of the groove 111 during the process of turning and returning the camera module 2 to the groove 111.

In another alternative embodiment, the control board 1001 controls the turning speed of the driving motor 31 to be reduced to the second rotation speed when the detecting component 5 detects that the detecting component is 30 ° with the bottom of the groove 111 during the process of turning and returning the camera module 2 to the groove 111.

It should be noted that the above embodiment is merely illustrative, and the control board 1001 controls the deceleration operation of the driving motor 31 according to the included angle between the control board 1001 and the bottom of the groove 111 during the process of turning the camera module 2 and returning to the groove 111. The present utility model does not limit the correspondence between the specific angle between the camera module 2 and the bottom of the groove 111 and the rotation speed of the driving motor 31. The user can be adaptively adjusted according to actual requirements.

In some embodiments, as shown in fig. 3, the detection assembly 5 includes a resistance ring 51 and a conductive contact 52.

The resistance ring 51 and the tilting mechanism 3 are coaxially connected, and can rotate along with the tilting mechanism 3, and the resistance of the resistance ring 51 appears to continuously vary in the circumferential direction.

Optionally, the adhesive is dispensing.

Specifically, the resistance ring 51 has a first diameter surface 511 and a second diameter surface, and the first diameter surface 511 and the second diameter surface are located at both ends of the resistance ring 51, respectively. The resistance values of the areas on the resistance changing ring are different, and the resistance values of the areas uniformly change along the circumferential direction of the resistance changing ring. Alternatively, the resistance values of the respective regions on the resistance rings sequentially increase in the counterclockwise direction of the first diameter surface 511.

The conductive contact 52 is electrically connected to the control board 1001. The conductive contact 52 protrudes beyond one side of the control board 1001. Optionally, the conductive contacts 52 are integrally connected to the control board 1001.

As shown in fig. 3, the conductive contacts 52 are U-shaped. Specifically, the groove walls on two opposite sides of the conductive contact 52 form a first contact portion and a second contact portion, respectively; the bottom of the conductive contact 52 is an insulating surface. The first contact part, the second contact part and the insulating surface form a U-shaped cavity.

Wherein the resistance variable ring 51 is sandwiched between the first contact portion and the second contact portion, a part of the first diameter surface 511 is connected to the first contact portion, and a part of the second diameter surface is connected to the second contact portion; a part of the wall body of the second peripheral wall of the resistance ring 51 is accommodated in the U-shaped cavity of the conductive contact 52.

The resistance ring 51 is electrically connected to the conductive contact 52 and the control board 1001 to form a detection circuit. In the process of following the rotation of the rotating shaft 32, the resistance ring 51 rotates and switches at a position between the first contact portion and the second contact portion, so that the resistance of the connected detection circuit is changed, and the current of the detection circuit is changed.

The resistance ring 51 is provided coaxially with the rotation shaft 32 and the imaging module 2, and can rotate at the same rotation speed as the driving motor 31. The control board 1001 can determine the turning angle of the resistance variable ring 51 according to the current change in the detection circuit, that is, the turning angle of the camera module 2 relative to the mounting seat 1, so that the control board 1001 can further control the turning speed of the driving motor 31 according to the turning angle of the camera module 2 relative to the mounting seat 1, and in the process of turning and homing the camera module 2 to the groove 111, when the camera module 2 approaches to the first position, the control board 1001 controls the driving motor 31 to run at a reduced speed.

The control board 1001 is electrically connected to the hall element 54. The control board 1001 can control the rotation speed of the drive motor 31 based on the detection result of the hall element 54. When the hall element 54 detects that the camera module 2 is turned over and returned to the first position and is close to the first position, the control board 1001 controls the driving motor 31 to run at a reduced speed so as to realize physical protection to the camera module 2.
