Next, a specific structure of the linear and rotary motion integrated mechanism 200 will be described:
as shown in fig. 3 and 4, the linear and rotary motion integrated mechanism 200 includes: a first driving motor 211, a second driving motor 212, a first driving wheel 221, a second driving wheel 222, a first fixed driven wheel 231, a second fixed driven wheel 232, a first movable driven wheel 241, a second movable driven wheel 242, a sliding plate 250, and a conveyor belt 260.

The base 100 is provided with a linear guide rail 110, and the sliding plate 250 is slidably disposed on the linear guide rail 110.

The loading jig 300 is mounted on the first movable driven wheel 241 or the second movable driven wheel 242.
The operation principle of the linear and rotary motion integrated mechanism 200 will be described below:
(1) Referring to fig. 5, the first driving motor 211 drives the first driving wheel 221 to rotate clockwise, and the second driving motor 222 drives the second driving wheel 222 to rotate counterclockwise, so that the rotation speeds of the first driving wheel 221 and the second driving wheel 222 are the same (the first fixed driven wheel 231 rotates clockwise, and the second fixed driven wheel 232 rotates counterclockwise); in this case, the slide plate 250 is linearly moved to the left along the linear guide rail 110 based on the driving of the conveyor belt 260, however, neither the first movable driven wheel 241 nor the second movable driven wheel 242 on the slide plate 250 is rotated, and thus the entire loading jig 300 is linearly moved to the left; once the first and second driving motors 211 and 222 stop driving, the loading jig 300 stops moving;
Similarly, the first driving motor 211 drives the first driving wheel 221 to rotate anticlockwise, and the second driving motor 222 drives the second driving wheel 222 to rotate clockwise, so that the rotation speeds of the first driving wheel 221 and the second driving wheel 222 are the same, and the whole loading fixture 300 moves towards the right side in a straight line;
(2) Referring to fig. 6, the first driving motor 211 drives the first driving wheel 221 to rotate clockwise, and the second driving motor 222 also drives the second driving wheel 222 to rotate clockwise, so that the rotation speeds of the first driving wheel 221 and the second driving wheel 222 are the same (the first fixed driven wheel 231 rotates clockwise, and the second fixed driven wheel 232 rotates clockwise); in this case, the sliding plate 250 stays in place without moving based on the transmission of the conveyor belt 260, and the first movable driven wheel 241 and the second movable driven wheel 242 on the sliding plate 250 rotate counterclockwise, so that the entire loading jig 300 stays in place for counterclockwise rotation; once the first and second driving motors 211 and 222 stop driving, the loading jig 300 stops moving;
Similarly, the first driving motor 211 drives the first driving wheel 221 to rotate anticlockwise, and the second driving motor 222 also drives the second driving wheel 222 to rotate anticlockwise, so that the rotation speeds of the first driving wheel 221 and the second driving wheel 222 are the same, and the whole loading jig 300 stays in place to perform clockwise rotation;
(3) Referring to fig. 7, the first driving motor 211 drives the first driving wheel 221 to rotate clockwise, and the second driving motor 222 does not perform power output (the second driving wheel 222 does not rotate), in this case (the first fixed driven wheel 231 rotates clockwise, the second fixed driven wheel 232 does not rotate), the sliding plate 250 moves linearly to the left along the linear guide rail 110 based on the transmission of the conveyor belt 260, and simultaneously, the first movable driven wheel 241 and the second movable driven wheel 242 on the sliding plate 250 rotate counterclockwise, so that the whole loading jig 300 moves linearly to the left and rotates counterclockwise;
Similarly, the first driving motor 211 drives the first driving wheel 221 to rotate counterclockwise, and the second driving motor 222 does not perform power output, so that the entire loading jig 300 rotates clockwise while moving straight to the right.
As described above, the linear and rotational motion integrated mechanism 200 can realize the linear reciprocating motion, the in-situ clockwise or counterclockwise rotation, and the rotation while the linear motion of the loading jig 300.
Next, a specific structure of the mode switching mechanism 400 will be described:
As shown in fig. 8 and 9, the mode switching mechanism 400 includes a mode switching power source 410 and a mode switching rotating lever 420 provided at an output end of the mode switching power source 410. The mode switching lever 420 has a triangular prism structure, and the mode switching lever having the triangular prism structure forms a first mode surface 421, a second mode surface 422, and a third mode surface 423. The first pattern surface 421 has a smooth planar structure; the second pattern surface 422 is sequentially provided with a plurality of bumps 422a at intervals; the third mode surface 423 has a parabolic arc surface structure.
The sliding plate 250 is pressed against one of the first pattern surface 421, the second pattern surface 422, and the third pattern surface 423 by the roller 251.
The operation principle of the mode switching mechanism 400 described above will be described:
the mode switching power source 410 drives the mode switching rotating rod 420 to rotate around the axis thereof, thereby realizing angle adjustment and conversion, so that the roller 251 on the sliding plate 250 is pressed on one of the first mode surface 421, the second mode surface 422 and the third mode surface 423;
When the roller 251 on the sliding plate 250 is pressed against the first mode surface 421, the first mode surface 421 has a smooth planar structure, the whole device is in a normal mode test state, and under the cooperation of the linear and rotary motion integrated mechanism 200, the normal mode test can be performed on the mobile phone in the loading jig 300; since the first pattern surface 421 has a smooth planar structure, the roller 251 of the sliding plate 250 may travel on the smooth planar structure more smoothly without shaking;
when the roller 251 on the sliding plate 250 is pressed against the second mode surface 422, a plurality of bumps 422a are sequentially arranged on the second mode surface 422 at intervals, the whole equipment is in a vibration mode test state, and the vibration mode test can be performed on the mobile phone in the loading jig 300 under the cooperation of the linear and rotary motion integrated mechanism 200; since the second pattern surface 422 is sequentially provided with a plurality of protrusions 422a at intervals, the roller 251 on the sliding plate 250 may periodically vibrate when walking on the plurality of protrusions 422a;
When the roller 251 on the sliding plate 250 is pressed against the third mode surface 423, the third mode surface 423 is in a parabolic arc surface structure, the whole equipment is in a drop mode test state, and under the cooperation of the linear and rotary motion integrated mechanism 200, the mobile phone in the loading jig 300 can be subjected to drop mode test; because the third mode surface 423 has a parabolic arc surface structure, the roller 251 on the sliding plate 250 can rapidly rise or fall when walking on the arc surface, and the mobile phone in the loading jig 300 can simulate a falling scene to form impact.
The linear and rotary motion integrated mechanism 200 can realize the linear reciprocating motion, the in-situ clockwise or anticlockwise rotation, and the linear motion and the rotation of the loading jig 300, and the mode switching mechanism 400 has multiple modes such as a common mode test, a vibration mode test, a drop mode test, and the like, and the multiple motion states in the linear and rotary motion integrated mechanism 200 and the multiple modes in the mode switching mechanism 400 can be combined at will according to specific test requirements.
As shown in fig. 3, it is particularly important to note that in the present invention, the belt 260 is particularly used, the belt 260 has an elastic belt structure, the belt 260 has very good elastic force and ductility, and an important bridge function is provided between the linear and rotary motion integrated mechanism 200 and the mode switching mechanism 400.
The important bridging function with respect to conveyor 260 is described as follows:
On the one hand, the linear and rotary motion integrated mechanism 200 can realize the linear reciprocating motion, the in-situ clockwise or anticlockwise rotation, the linear motion, the rotation and other motions of the loading jig 300 based on the transmission of the conveyor belt 260;
On the other hand, when the roller 251 on the sliding plate 250 travels on the second mode surface 422 and the third mode surface 423, particularly when the roller travels on the third mode surface 423, the entire sliding plate 250, the first movable driven wheel 241, the second movable driven wheel 242, and the loading jig 300 are greatly raised or lowered, the elastic force of the conveyor belt 260 tightly presses the sliding plate 250 on the mode surface by the first movable driven wheel 241 and the second movable driven wheel 242, the sliding plate 250 is prevented from being separated, and the ductility of the conveyor belt 260 is well adapted to the great raising and lowering movements of the respective components;
it can be seen that the conveyor 260 is a member selected and particularly used in the present invention, and has a great effect and excellent effect.
In this embodiment, the mode switching power source 400 is a motor driving structure, and drives the mode switching rotating rod 420 to rotate in an electric manner.
In another embodiment, the mode switching power source 400 is a hand-operated driving structure, such as a hand-operated rotating handle structure commonly used in the market, and the mode switching rotating rod 420 is manually driven to rotate.
Of course, it is noted that the mode switching lever 420 has a triangular prism structure, and the mode switching lever with the triangular prism structure forms a first mode surface 421, a second mode surface 422, and a third mode surface 423, and a junction between the mode surfaces may be rounded, so that the roller 251 on the sliding plate 250 may be more smoothly transitioned from one mode surface to the other mode surface.
In this embodiment, the loading jig 300 has a hollow cylindrical structure, and the loading jig 300 does not consider a cylindrical structure with an angular edge. Because the purpose of whole equipment is whether the test cell-phone internals assemble stably, and the tubular structure that has the edges and corners can make the outward appearance of cell-phone appear damaging more easily.
Further, the opening of the loading fixture 300 is provided with a sealing cover 310 (as shown in fig. 3 and 4), and the mobile phone can be completely contained in the cavity of the loading fixture 300 by arranging the sealing cover 310, so that the mobile phone is prevented from falling off in the testing process.
As shown in fig. 8, in the present embodiment, the linear guide rail 110 is a straight through groove structure formed on the base 100, the sliding plate 250 is provided with a limiting rod 252, the limiting rod 252 is slidably inserted into the linear guide rail 110, and the roller 251 is disposed on the limiting rod 252. Such a structural design can make the sliding plate 250 more stably mounted on the base 100. In the present embodiment, the number of the linear guides 110 is two.
In the present embodiment, a moving wheel 101 (shown in fig. 1) is provided at the bottom of the base 100. By providing the moving wheel 101, the entire test apparatus can be displaced very easily.
