Detailed ways

The embodiments of the present application relate to a driving device, a circuit board and a communication device. The driving device, a circuit board and a communication device will be described in detail below with reference to the drawings.

On the one hand, an embodiment of the present application provides a driving device. Referring to FIG. 7, the driving device is used to drive the first moving part 1 to move along the first straight line L1 and to drive the second moving part 2 to move along the second straight line. L2 moves, and the first straight line L1 and the second straight line L2 are perpendicular to each other.

7, the driving device includes: a driving wheel 3, a first transmission mechanism 4, and a second transmission mechanism 5. Referring to FIG. 9, the driving wheel 3 is formed with an engaging portion 31 and a non-engaging portion 32, and the first transmission mechanism 4 is engaged with When the portion 31 is engaged, the second transmission mechanism 5 is in the position of the non-engaging portion 32, and the driving wheel 3 drives the first moving part 1 to move along the first straight line L1 through the first transmission mechanism 4; When the meshing part 31 is engaged, the first transmission mechanism 4 is at the position of the non-meshing part 32, and the driving wheel 3 drives the second moving part 2 to move along the second straight line L2 through the second transmission mechanism 5.

When the meshing portion 31 of the driving wheel 3 meshes with the first transmission mechanism 4, the driving wheel 3 can mesh and drive with the first transmission mechanism 4 to drive the first moving member 1 to move along the first straight line L1. However, due to the The second transmission mechanism 5 cooperates with the non-engaging part 32, the driving wheel 3 will not drive the second transmission mechanism 5 to move, and the second moving part 2 will stand still; when the engagement part 31 of the driving wheel 3 is engaged with the second transmission mechanism 5 At this time, the driving wheel 3 can mesh with the second transmission mechanism 5 to drive the second moving member 2 to move along the second straight line L2. However, since the first transmission mechanism 4 cooperates with the non-engaging portion 32, the driving wheel 3 does not Will drive the first transmission mechanism 4 to move, and the first moving part 1 will stand still. Therefore, the first moving part 1 and the second moving part 2 are realized by the timely cooperation of the meshing part 31 and the non-meshing part 32 formed on the driving wheel 3 with the corresponding first transmission mechanism 4 and the second transmission mechanism 5 Independent movement in each direction.

In specific implementation, only the driving wheel 3 is driven to rotate, and the movement of the first moving part 1 along the first straight line L1 and the movement of the second moving part 2 along the first straight line L2 are realized. Compared with the prior art that one drive mechanism drives the first moving member 1 to move along the first straight line L1, and another drive mechanism drives the second moving member 2 to move along the second straight line L2, the operation of the present application is simpler and significantly improved Man-machine exchange experience. At the same time, if the movement sequence of the first moving part 1 and the second moving part 2 is fixed, the prior art may affect the performance of other related parts due to the wrong operation sequence of the two driving mechanisms. This phenomenon will not appear in the application.

The driving wheel 3 and the second transmission mechanism 5 can be arranged in a variety of situations. For example, referring to FIG. 7, the driving wheel 3 and the second transmission mechanism 5 are installed on the first moving part 1, so that there is no need to separately set them for installation. The mounting plate of the driving wheel 3 and the second transmission mechanism 5; for another example, the driving wheel 3 and the second transmission mechanism 5 are not installed on the first moving part 1, but are separately arranged on the mounting plate, and the second transmission mechanism 5 It is directly connected to the second moving part 2. In this application, in order to simplify the structure and save installation space, the driving wheel 3 and the second transmission mechanism 5 are installed on the first moving part 1.

If the driving wheel 3 and the second transmission mechanism 5 are mounted on the first moving part 1, the second transmission mechanism 5 is fixedly connected to the second moving part 2, which will cause the first moving part 1 to follow the first straight line L1 When moving, it will also drive the second moving part 2 to move. In order to ensure that the second moving part 2 is stationary when the first moving part 1 moves, referring to Figures 7 and 8, the second transmission mechanism 5 is provided with a mechanism for communicating with the second moving part. When the first transmission mechanism 4 drives the first moving part 1 to approach the second moving part 2, the second transmission mechanism 5 is connected to the second moving part 2 through the insertion structure 7 and the first When the transmission mechanism 4 drives the first moving part 1 to move away from the second moving part 2, the second transmission mechanism 5 is separated from the second moving part 2 by the plug structure 7. That is, when the first moving part 1 is close to the second moving part 2, the second transmission mechanism 5 is connected with the second moving part 2, so that the second transmission mechanism 5 can drive the second moving part 2 to move. When the moving part 1 moves away from the second moving part 2, the second transmission mechanism 5 is separated from the second moving part 2, so as to ensure that when the first moving part 1 moves, the second moving part 2 is stationary, realizing the first moving part 1 and the second moving part 2 move independently in their respective directions without interfering with each other.

9, the outer edge of the driving wheel 3 is provided with a first meshing tooth 311 and a second meshing tooth 312, and the outer edge of the driving wheel 3 is located between the first meshing tooth 311 and the second meshing tooth 312 to form a smooth section. A meshing tooth 311 and a second meshing tooth 312 form a meshing part 31, and the smooth section forms a non-meshing part 32. When the first transmission mechanism 4 meshes with the first meshing tooth 311, the second transmission mechanism 5 is in sliding engagement with the smooth section When the second transmission mechanism 5 is engaged with the second meshing tooth 312, the first transmission mechanism 4 is slidingly engaged with the smooth section. The first meshing teeth 311 and the second meshing teeth 312 are used to form the meshing portion 31, and the smooth section is used to form the non-meshing portion 32, which has a simple structure and is convenient to manufacture. When the first meshing tooth 311 meshes with the first transmission mechanism 4 for transmission, the smooth section is slidingly engaged with the second transmission mechanism 5. At this time, the first moving member 1 moves and the second moving member 2 is stationary, as the driving wheel 3 continues When rotating, the smooth section is slidingly fitted with the first transmission mechanism 4, and the second meshing tooth 312 meshes and transmits with the second transmission mechanism 5. At this time, the second moving part 2 moves and the first moving part 1 is stationary. Therefore, this The meshing part and the non-meshing part of the structure can realize that when one of the first moving part 1 and the second moving part 2 is stationary, the other moves, and the action is continuous and uninterrupted.

In some embodiments, referring to FIG. 9, the first transmission mechanism 4 includes: a transition wheel 41 for meshing transmission and a push wheel 42. The outer edge of the transition wheel 41 is provided with a first driven tooth that meshes with the first meshing tooth 311. 411 and the first smooth section 412 slidingly fitted with the smooth section, that is, as the driving wheel 3 rotates, when the first meshing tooth 311 meshes with the first driven tooth 411, it will drive the transition wheel 41 to rotate , Which in turn drives the push wheel 42 to rotate. When the smooth section is matched with the first smooth section 412, because the two are in a sliding fit, the transition wheel 41 will not rotate under the rotation of the driving wheel 3, so the push wheel 42 is also at rest Employing the sliding fit between the smooth section and the first smooth section 412 can ensure that the transition wheel 41 and the push wheel 42 are basically in a static state, and prevent the first moving member 1 from moving when the second moving member 2 moves. Of course, the transition wheel 41 can also be provided with meshing teeth that cooperate with the smooth section on the drive wheel 3, so that the transition wheel 41 will not rotate under the drive of the drive wheel 3. However, in order to improve the overall driving device For work performance, the smooth section and the first smooth section 412 are slidingly matched, so that the transition wheel 41 will not rotate under the drive of the driving wheel 3.

In order to further simplify the structure, the transition wheel 41 and the pushing wheel 42 are rotatably mounted on the first moving part 1, so that the driving wheel 3, the transition wheel 41 and the pushing wheel 42 will move with the movement of the first moving part 1, in order to adopt The pushing wheel 42 pushes the first moving member 1 to move. Referring to FIG. 7, a fixing member 43 is provided on the rotating path of the pushing wheel 42. When the pushing wheel 42 rotates to abut against the fixing member 43, the fixing member 43 pairs the pushing wheel. 42 applies thrust to move the first moving member 1 along the first straight line. That is, when the pushing wheel 42 is rotating, the pushing wheel 42 will exert a pushing force on the fixed part 43, and since the fixed part 43 is stationary, the fixed part 43 will exert a reaction force on the pushing wheel 42, so that the first moving part 1 It can move along the first straight line.

The position of the fixing member 43 has many situations. For example, referring to FIG. 9, the fixing member 43 is arranged on the side of the first moving member 1 and cooperates with the pushing wheel 42; referring to FIG. 10, the outer edge of the pushing wheel 42 is opened There is a card slot 421. The card slot 421 has a first contact surface 422 and a second contact surface 423 opposite to each other. The fixing member 43 is located in the card slot 421. The fixing member 43 has a third contact surface 431 and a fourth contact surface. The contact surface 432, when the push wheel 42 rotates in the first rotation direction, the first abutment surface 422 abuts the third abutment surface 431 to apply a thrust in the first direction to the push wheel 42. When 42 rotates in the second rotation direction, the second abutting surface 423 abuts against the fourth abutting surface 432 to apply a thrust in the second direction to the pushing wheel 42, wherein the first rotation direction and the second rotation The directions are opposite, and the first direction is opposite to the second direction and parallel to the first straight line respectively.

9 and 10, when the push wheel 42 rotates in the first rotation direction (clockwise), the first abutment surface 422 abuts the third abutment surface 431 to apply a thrust in the direction L11 to the push wheel 42 , To move the first moving member 1 in the direction L11. When the pushing wheel 42 rotates in the second rotation direction (counterclockwise), the second abutting surface 423 abuts the fourth abutting surface 432 to apply a thrust in the direction opposite to the direction L11 to the pushing wheel 42 to make the first A moving member 1 moves in a direction opposite to the direction L11.

In order to ensure that the first moving member 1 moves smoothly and without deviation along the first straight line under the thrust of the fixed member 43, the third abutting surface 431 and the fourth abutting surface 432 are both perpendicular to the first straight line. In this way, the thrust exerted by the third contact surface 431 on the first contact surface 422 is basically parallel to the first straight line. Similarly, the thrust exerted by the fourth contact surface 432 on the second contact surface 423 is also basically the same as the first straight line. The lines are parallel. In this way, there is no need to provide a guiding structure for guiding the first moving member 1 to move along the first straight line.

7, the second transmission mechanism 5 includes a follower 51 rotatably mounted on the first moving part 1, and a pulling part 52 slidably mounted on the first moving part 1 and engaged with the follower 51 for transmission. The pulling part The sliding direction of 52 is parallel to the second straight line L2. Referring to FIG. 11, the pulling member 52 has transmission teeth 521 arranged along its extending direction and meshing with the driven member 51.
