In this embodiment, the push top 294 is a trapezoidal body, and one end of the push top 294 having a larger cross section is connected to the pressing portion 292. .

Referring to FIG. 3 and FIG. 4 together, assembling the electronic device 100 can be performed as follows:

First, the second elastic arm 246 of the torsion spring 24 is abutted between the two ribs 222 of the support member 22. Thereafter, the first rotating shaft 23 is sequentially passed through the sleeve 2222 of the support member 22 and the fixing portion of the torsion spring 24. 242 and sleeve 2224. The second shaft 28 is then sequentially passed through the passage 2226 of the support member 22, the sleeve 276 of the support arm 27, and the passage 2228 such that the support member 22 and the support arm 27 are rotatable about the second shaft 28. The free end 226 of the support member 22 is extended from the receiving hole 1222 of the housing 10 to the housing 10, and the sleeves 2222, 2224 are received in the recesses. Within 256.

Then, the pressing portion 292 of the switch 29 is aligned with the mounting hole 14 of the housing 10, and the top switch 29 is pushed outward by the mounting groove 12 of the housing 10 until the pressing portion 292 exposes the housing 10. Next, a holding member 25 is taken, and the sliding groove 252 is respectively aligned with the two protrusions 1224 on one side of the receiving hole 1222, and the pushing and holding member 25 is received in the sliding groove 252. The other holding member is attached to the other side of the receiving hole 1222 according to the above steps, and finally one side of the holding member 25 provided with the recess 256 is oppositely disposed. Further, the two ends of the resetting member 26 are respectively fixed to the fixing portions 258 of the holding members 25 facing each other. Wherein, the assembled gripper 25 is biased by the restoring member 26, and its wedge surface 258 holds the push top 294 of the switch 29 in the middle.

Finally, the substrate 21 (see FIG. 1) is provided with one surface of the slider 212 facing the mounting groove 12 of the housing 10, and the substrate 21 is pushed to engage the substrate 21 into the holding portion 1242. Thus, the holding member 25 is held between the substrate 21 and the housing 10, that is, the two holding members 25 can only slide toward or away from each other in the direction of the sliding slot 252 under the restriction of the guide post 1224 and the sliding slot 252. The electronic device 100 is assembled.

When the support mechanism 20 is not in use, the support member 22 is received in the receiving hole 1222. At this time, one of the locking pin 274 and the holding member 25 locks the groove 256 to rest the support member 22 on the housing 10, and the two elastic arms 244 of the torsion spring 24 are bent toward each other to accumulate a certain elasticity. force.

Referring to FIG. 5 and FIG. 6 together, when the bracket mechanism 20 is needed, the switch 29 is pressed and the support member 22 is automatically opened. The specific working process is as follows. After the switch 29 is pressed, the push top 294 of the switch 29 will move downward along the wedge surface 258 and squeeze the two grip members 25 to slide back there so that the lock pin 274 of the support arm 27 and the recess 256 unlocked. The support member 22 is under the elastic force of the torsion spring 24, and the free end of the support member 22 226 will eject the receiving hole 1222 of the housing 10, and together drive the guiding groove 272 of the supporting arm 27 to slide along the guide rail 212 toward the torsion spring 24. Until the lock pin 274 slides down to the recess 256 and relocks, the support arm 27 stops sliding. At this time, the support member 22 and the housing 10 form a support angle, and the support member 22, the support arm 27 and the housing 10 together form a stable triangle so that the housing 10 is stably supported by the bracket mechanism 20. If it is necessary to open a large angle between the support member 22 and the housing 10, it is only necessary to continue to press the switch 29, and the two holding members 25 are separated by a large distance, so that the locking pin 274 slides in and locks closer to the twist. The groove 24 of the spring 24 is 256.

It can be understood that the role of the guide post 1224 on the housing 10 cooperates with the sliding slot 252 on the gripping member 25 to allow relative movement of the gripping member 25. Therefore, the guide post 1224 is not limited to being disposed on the casing 10, and the same effect can be achieved by arranging the guide post 1224 on the substrate 21.

It can be understood that the base plate 21 and the bottom wall 122 of the housing 10 hold the holding member 25 in the middle to maintain the locking pin 274 of the support arm 27 from being disengaged from the holding member 25 and locked in the recess 256 of the holding member 25. However, in order to achieve the above-mentioned object, a guide groove may be respectively formed on both sides of the guide rail 212 of the substrate 21, and a guide pin is respectively protruded on the opposite side walls of the guide groove 272 of the support arm 27. The guide pin is slidably disposed in the guiding groove, so that the locking pin 274 can be ensured not to be disengaged from the holding member 25 and locked in the recess 256 of the holding member 25.

It can be understood that the mounting groove 216 of the substrate 21 cooperates with the groove 1226 of the housing 10 to define a cylindrical mounting cavity for mounting the sleeves 2222, 2224 of the support member 22. Therefore, a cover body provided with the groove is mounted on the substrate 21 to form the mounting cavity, and the sleeves 2222, 2224 of the support member 22 can also be rotatably mounted on the substrate 21.

One end of the support member 22 in the bracket mechanism 20 of the present invention is rotatably coupled to the housing 10 One end of the support arm 27 is also rotatably coupled to the support member 22, and the other end of the support arm 27 is held between the holding members 25 in the housing 10, so that the support member 22, the support arm 27, The housing 10 is formed in a stable triangle so that the housing 10 is stably supported.

If the support angle between the support member 22 and the housing 10 needs to be changed, the holding members 25 are separated from each other by the switch 29 on the housing 10, and the free end 226 of the support member 22 is under the elastic force of the torsion spring 24. That is, the housing 10 is automatically bounced to form a larger support angle between the support member 27 and the housing 10, so that the bracket mechanism 20 of the present invention is easy to open.

Stop pressing the switch 29, the other end of the support arm 27 will be held in the middle of the holding member 25. By repeating the above actions, different support angles can be formed between the stay member 27 and the housing 10 to cause the bracket mechanism 20 to form different magnitudes of supporting force for the housing 10. Therefore, the electronic device 100 of the present invention has a large supporting force and an angle is convenient for adjustment.
