Detailed Description
The embodiments of the present application relate to a driving device, a circuit board, and a communication device, and the driving device, the circuit board, and the communication device are described in detail below with reference to the drawings.
In one aspect, the present embodiment provides a driving device, referring to fig. 7, for driving the first moving member 1 to move along a first straight line L1, and for driving the second moving member 2 to move along a second straight line L2, where the first straight line L1 is perpendicular to the second straight line L2.
Referring to fig. 7, the driving apparatus includes: the driving wheel 3, the first transmission mechanism 4 and the second transmission mechanism 5, referring to fig. 9, the driving wheel 3 is formed with an engaging part 31 and a non-engaging part 32, when the first transmission mechanism 4 is engaged with the engaging part 31, the second transmission mechanism 5 is at the position of the non-engaging part 32, and the driving wheel 3 drives the first moving member 1 to move along a first straight line L1 through the first transmission mechanism 4; in the case that the second transmission mechanism 5 is engaged with the engaging portion 31, the first transmission mechanism 4 is located at the position of the non-engaging portion 32, and the driving wheel 3 drives the second moving member 2 to move along the second straight line L2 through the second transmission mechanism 5.
When the engaging portion 31 of the driving wheel 3 is engaged with the first transmission mechanism 4, the driving wheel 3 can be engaged with the first transmission mechanism 4 for transmission so as to drive the first moving member 1 to move along the first straight line L1, but since the second transmission mechanism 5 is engaged with the non-engaging portion 32, the driving wheel 3 cannot drive the second transmission mechanism 5 to move, and the second moving member 2 is stationary; when the engaging portion 31 of the driving wheel 3 engages with the second transmission mechanism 5, the driving wheel 3 can engage with the second transmission mechanism 5 for transmission to drive the second moving member 2 to move along the second straight line L2, but since the first transmission mechanism 4 is engaged with the non-engaging portion 32, the driving wheel 3 does not drive the first transmission mechanism 4 to move, and the first moving member 1 is stationary. Therefore, by the timely cooperation of the engaging portion 31 and the non-engaging portion 32 formed on the driving wheel 3 and the corresponding first transmission mechanism 4 and second transmission mechanism 5, the independent movement of the first moving member 1 and the second moving member 2 in the respective directions is realized.
During specific implementation, only the driving wheel 3 needs to be driven to rotate, so that the first moving part 1 moves along the first straight line L1, and the second moving part 2 moves along the first straight line L2. Compare current drive first moving member 1 through a actuating mechanism and move along first straight line L1, another actuating mechanism drives second moving member 2 and moves along second straight line L2, the operation of this application is more simple and convenient, can obviously improve man-machine exchange and experience, and simultaneously, if the motion sequence of first moving member 1 and second moving member 2 is both regular, prior art can be because two actuating mechanism operation sequence errors, and then influence the performance of other relevant parts, however, this kind of phenomenon can not appear in this application.
The arrangement positions of the driving wheel 3 and the second transmission mechanism 5 can be variously set, for example, referring to fig. 7, the driving wheel 3 and the second transmission mechanism 5 are mounted on the first moving member 1, so that it is not necessary to separately provide a mounting plate for mounting 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 mounted on the first moving member 1 but are separately provided on a mounting plate, and the second transmission mechanism 5 is directly connected to the second moving member 2. In order to simplify the structure and save the installation space, the driving wheel 3 and the second transmission mechanism 5 are installed on the first moving member 1.
If the driving wheel 3 and the second transmission mechanism 5 are installed on the first moving member 1, the second transmission mechanism 5 is fixedly connected with the second moving member 2, so that the first moving member 1 can move along the first straight line L1, the second moving member 2 can also be driven to move, in order to ensure that the first moving member 1 moves, the second moving member 2 is static, referring to fig. 7 and 8, the second transmission mechanism 5 is provided with an insertion structure 7 for connecting with or separating from the second moving member 2, when the first transmission mechanism 4 drives the first moving member 1 to be close to the second moving member 2, the second transmission mechanism 5 is connected with the second moving member 2 through the insertion structure 7, when the first transmission mechanism 4 drives the first moving member 1 to move towards the direction far away from the second moving member 2, and the second transmission mechanism 5 is separated from the second moving member 2 through the insertion structure 7. That is to say, when the first moving member 1 is close to the second moving member 2, the second transmission mechanism 5 is connected with the second moving member 2, so the second transmission mechanism 5 can drive the second moving member 2 to move, when the first moving member 1 moves towards the direction far away from the second moving member 2, the second transmission mechanism 5 is separated from the second moving member 2, and further when the first moving member 1 moves, the second moving member 2 is static, and the first moving member 1 and the second moving member 2 move independently along the directions of the first moving member 1 and the second moving member 2 without mutual interference.
Referring to fig. 9, the outer edge of the driving wheel 3 is provided with a first engaging tooth 311 and a second engaging tooth 312, a smooth section is formed on the outer edge of the driving wheel 3 and between the first engaging tooth 311 and the second engaging tooth 312, the first engaging tooth 311 and the second engaging tooth 312 form an engaging portion 31, the smooth section forms a non-engaging portion 32, the second transmission mechanism 5 is in sliding fit with the smooth section in the case that the first transmission mechanism 4 is engaged with the first engaging tooth 311, and the first transmission mechanism 4 is in sliding fit with the smooth section in the case that the second transmission mechanism 5 is engaged with the second engaging tooth 312. The first meshing tooth 311 and the second meshing tooth 312 are adopted to form the meshing part 31, and the smooth section forms the non-meshing part 32, so that the structure is simple, and the processing and the manufacturing are convenient. When the first meshing teeth 311 and the first transmission mechanism 4 are in meshing transmission, the smooth section is in sliding fit with the second transmission mechanism 5, at the moment, the first moving part 1 moves, the second moving part 2 is static, along with the continuous rotation of the driving wheel 3, the smooth section is in sliding fit with the first transmission mechanism 4, the second meshing teeth 312 are in meshing transmission with the second transmission mechanism 5, at the moment, the second moving part 2 moves, the first moving part 1 is static, therefore, the meshing part and the non-meshing part which adopt the structure can realize that when one of the first moving part 1 and the second moving part 2 is static, the other moves continuously without interruption.
In some embodiments, referring to fig. 9, first transmission 4 comprises: the transition wheel 41 and the pushing wheel 42 are in meshing transmission, a first driven tooth 411 meshed with the first meshing tooth 311 and a first smooth section 412 in sliding fit with the smooth section are arranged on the outer edge of the transition wheel 41, that is, along with the rotation of the driving wheel 3, when the first meshing tooth 311 is meshed with the first driven tooth 411, the transition wheel 41 is driven to rotate, and then the pushing wheel 42 is driven to rotate, and when the smooth section is matched with the first smooth section 412, because of the sliding fit between the smooth section and the first smooth section 412, the transition wheel 41 cannot rotate under the rotation of the driving wheel 3, so that the pushing wheel 42 is also static, and by adopting the sliding fit between the smooth section and the first smooth section 412, the transition wheel 41 and the pushing wheel 42 can be basically in a static state, and when the second moving part 2 moves, the first moving part 1 also moves. Of course, the transition wheel 41 may also be provided with engaging teeth that are engaged with the smooth section on the driving wheel 3, so that the transition wheel 41 cannot be driven by the driving wheel 3 to rotate, but in order to improve the working performance of the entire driving device, the smooth section is slidably engaged with the first smooth section 412, so that the transition wheel 41 cannot be driven by the driving wheel 3 to rotate.
In order to further simplify the structure, the transition wheel 41 and the pushing wheel 42 are rotatably mounted on the first moving member 1, such that the driving wheel 3, the transition wheel 41 and the pushing wheel 42 move along with the movement of the first moving member 1, and in order to push the first moving member 1 to move using the pushing wheel 42, referring to fig. 7, a fixing member 43 is provided on a path along which the pushing wheel 42 rotates, and in a case where the pushing wheel 42 rotates to abut against the fixing member 43, the fixing member 43 applies a pushing force to the pushing wheel 42, so that the first moving member 1 moves along the first straight line. That is, during the rotation of the pushing wheel 42, the pushing wheel 42 will exert a pushing force on the fixing member 43, and since the fixing member 43 is stationary, the fixing member 43 will exert a reaction force on the pushing wheel 42, so that the first moving member 1 can move along the first straight line.
The position of the fixed member 43 has various conditions, for example, referring to fig. 9, the fixed member 43 is arranged at the side of the first moving member 1 and is engaged with the pushing wheel 42; referring to fig. 10, a locking groove 421 is formed in an outer edge of the pushing wheel 42, the locking groove 421 has a first abutting surface 422 and a second abutting surface 423 which are opposite to each other, the fixing member 43 is located in the locking groove 421, the fixing member 43 has a third abutting surface 431 and a fourth abutting surface 432 which are opposite to each other, when the pushing wheel 42 rotates in a first rotation direction, the first abutting surface 422 abuts against the third abutting surface 431 to apply a thrust in the first direction to the pushing wheel 42, and when the pushing wheel 42 rotates in a 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 is opposite to the second rotation direction, and the first direction is opposite to the second direction and is parallel to the first straight line.
Referring to fig. 9 and 10, when the push wheel 42 rotates in the first rotation direction (clockwise), the first abutment surface 422 abuts against 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 push wheel 42 rotates in the second rotational direction (counterclockwise), the second abutment surface 423 abuts against the fourth abutment surface 432 to apply a thrust in a direction opposite to the direction L11 to the push wheel 42 to move the first moving member 1 in a direction opposite to the direction L11.
In order to ensure the smooth and unbiased movement of the first moving member 1 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 force applied by the third contact surface 431 to the first contact surface 422 is substantially parallel to the first straight line, and similarly, the thrust force applied by the fourth contact surface 432 to the second contact surface 423 is also substantially parallel to the first straight line. This eliminates the need for a guide structure for guiding the first moving member 1 to move along the first straight line.
