The first elastic member 44 can be, but is not limited to, a compression spring. The swinging member 42 is provided with a first conductive portion 421 and a second conductive portion 422 at intervals. The connecting portion 43 2, a first contact point 4321 and a second contact point 4322 are provided on the upper surface, which correspond to the first conductive part 421 and the second conductive part 422, respectively, that is, the first conductive part 421 and the second conductive part 422 are insulated, the first contact point 4321 and the second contact point 4322 are insulated, the first contact point 4321 and the second contact point 4322 are respectively used to electrically connect to the positive and negative poles of the power supply, the first electrode and the second electrode are respectively electrically connected to the first conductive part 421 and the second conductive part 422, and the electrical connection is connected through a conductive component, and the conductive component in this embodiment is a wire. It is worth mentioning that the power supply can be an external power supply device or a battery arranged inside the smart bracket, and this embodiment does not limit it here.

[0065] The intelligent bracket of the embodiment of the present invention includes a clamping component, a driving member 3 for driving the clamping component to clamp the electronic device, and a double-pole double-throw switch 4 electrically connected to the driving member 3, the double-pole double-throw switch 4 includes a swinging member 42 and a first connecting member 43, the swinging member 42 is provided with a first conductive portion 421 and a second conductive portion 422 at intervals, the first connecting member 43 is provided with a first contact point 4321 and a second contact point 4322 corresponding to the first conductive portion 421 and the second conductive portion 422, respectively, the first contact point 4321 and the second contact point 4322 are respectively used for It is electrically connected to the positive and negative electrodes of the power supply, and the first electrode and the second electrode are electrically connected to the first conductive part 421 and the second conductive part 422 respectively. When the electronic device presses the first connecting member 43, the first contact point 4321 and the second contact point 4322 of the first connecting member 43 abut against the first conductive part 421 and the second conductive part 422 respectively, and the positive and negative electrodes of the power supply are electrically connected to the first electrode and the second electrode of the driving member 3 respectively, thereby driving the clamping assembly to clamp the electronic device, so that the electronic device can be quickly fixed to the smart bracket with one hand.

[0066] Specifically, the pressing portion 431 of the first connecting member 43 is arranged on the surface of the switch housing 41, and the pressing portion 431 extends toward the inside of the switch housing 41 to form a connecting portion 432. The first elastic member 44 is sleeved on the pressing portion 431, and the end of the pressing portion 431 away from the connecting portion 432 is provided with a protruding structure to facilitate pressing. The two ends of the first elastic member 44 respectively abut against the protruding structure and the surface of the switch housing 4, and an anti-slip structure is provided on the connecting portion 432, which abuts against the inner wall of the switch housing 4. The user presses the pressing portion 431 of the first connecting member 43 to compress the first elastic member 44 by using the electronic device. When the user removes the electronic device, due to the setting of the anti-slip structure, the first connecting member 43 will not fall off the switch housing 41.

[0067] Combination Figure 1 , Figure 3 , Figure 5 as well as Figure 6 In the natural state, no electronic device is placed on the smart bracket, and the equivalent circuit between the driver 3 and the double-pole double-throw switch 4 is in an open circuit state, that is, the voltage of the power supply cannot be applied to the first electrode and the second electrode of the driver 3. Figure 7 As shown, when the user places the electronic device on the smart bracket, the user can use the electronic device to press the pressing portion 431 of the first connecting member 43, and the first connecting member 43 moves toward the direction close to the swinging member 42, and then the first contact point 4321 and the second contact point 4322 of the connecting portion 432 of the first connecting member 43 abut against the first conductive portion 421 and the second conductive portion 422 respectively. At this time, as shown in FIG. Figure 8 As shown, the equivalent circuit between the driving member 3 and the double-pole double-throw switch 4 is in a conductive state, the first electrode is electrically connected to the positive electrode of the power supply via the first contact point 4321, and the second electrode is electrically connected to the negative electrode of the power supply via the second contact point 4322, so that the driving member 3 is energized and drives the first clamping arm 11 and the second clamping arm 12 to approach each other. It should be noted that Figure 5 and Figure 6 "L1" and "L2" refer to the positive electrical signals of the power supply, "N1" and "N2" refer to the negative electrical signals of the power supply, and Figure 7 , Figure 8 , Fig.11 , Fig.12 as well as Fig.13 The symbols in refer to the same as above.

[0068] In one embodiment of the present invention, Figures 1 to 5 As shown, the intelligent bracket further includes a dynamic-static contact piece 5 provided on the first clamping arm 11 , and the first contact point 4321 is electrically connected to the positive pole of the power supply through the dynamic-static contact piece 5 .

[0069] Specifically, Figure 3 and Figure 4 As shown, the dynamic and static contact piece 5 includes a tension arm 51, a dynamic arm 52 spaced apart from and arranged opposite to the tension arm 51, a second elastic member 53 connected to the tension arm 51 and the dynamic arm 52 at both ends, and a static arm 54 arranged between the tension arm 51 and the dynamic arm 52. The second elastic member 53 can be but is not limited to a compression spring or a torsion spring. The dynamic arm 52 is arranged on a side of the tension arm 51 away from the second clamping arm 12. A third contact point 521 and a first magnetic pole 522 are spaced apart on the dynamic arm 52. A fourth contact point 541 corresponding to the third contact point 521 and a second magnetic pole 542 corresponding to the first magnetic pole 522 are provided on the static arm 54. The first magnetic pole 522 and the second magnetic pole 542 have opposite magnetic properties. The third contact point 521 is used to be electrically connected to the positive pole of the power supply. The fourth contact point 541 is electrically connected to the first conductive portion 421. The electrical connection is made by connecting through a conductive component. In this embodiment, the conductive component is an electric wire. In the smart bracket of this embodiment, the first magnetic pole 522 is the north pole and the second magnetic pole 542 is the south pole. It is understandable that the first magnetic pole 522 can also be set as the south pole and the second magnetic pole 542 can be set as the north pole accordingly.

[0070] Combination Figure 3 and Figure 4 When the first clamping arm 11 and the second clamping arm 12 do not clamp the electronic device, the first magnetic pole 522 and the second magnetic pole 542 are attracted together, and the third contact point 521 and the fourth contact point 541 are in contact, and the static and dynamic contact piece 5 is in a through state. Figures 9 and 10 When the first clamping arm 11 and the second clamping arm 12 clamp the electronic device, the electronic device squeezes the tension arm 51, and the tension arm 51 moves toward the direction close to the dynamic arm 52, and the second elastic member 53 is compressed. When the elastic force of the second elastic member 53 can overcome the magnetic force between the first magnetic pole 522 and the second magnetic pole 542, the elastic force of the second elastic member 53 causes the dynamic arm 52 to move away from the static arm 54. At this time, the first magnetic pole 522 and the second magnetic pole 542 are spaced apart, and the third contact point 521 and the fourth contact point 541 are spaced apart, as shown in FIG. Fig.11 As shown, the equivalent circuit between the driving member 3 and the double-pole double-throw switch 4 is in an open circuit state, that is, the voltage of the power supply cannot be applied to the first electrode and the second electrode of the driving member 3, and the driving member 3 stops driving the first clamping arm 11 and the second clamping arm 12 to move relative to each other.

[0071] It is worth mentioning that the driving member 3 of the present embodiment is a DC motor. When the DC motor stops driving, the second elastic member 53 on the dynamic and static contact piece 5 is compressed, and the second elastic member 53 has elastic force. In order to prevent the elastic force of the second elastic member 53 from causing the first clamping arm 11 and the second clamping arm 12 to separate from each other, the elastic force generated by the compression of the second elastic member 53 can be overcome by setting the attraction between the stator and the rotor of the DC motor or the friction force of the entire transmission system, so that the second elastic member 53 will not rebound.

[0072] In one embodiment of the present invention, Figure 5 As shown, the switch housing 41 is provided with a first support member 45 rotatably connected to the swing member 42, the two ends of the first conductive portion 421 are respectively located on both sides of the first support member 45, the two ends of the second conductive portion 422 are respectively located on both sides of the first support member 45, the first contact point 4321 and the second contact point 4322 correspond to one end of the first conductive portion 421 close to the first connecting member 43 and one end of the second conductive portion 422 close to the first connecting member 43 respectively; the double-pole double-throw switch 4 also includes a third elastic member 46 disposed on one side of the swing member 42 away from the first connecting member 43 and respectively located on both sides of the first support member 45 and the first elastic member 46 disposed on both sides of the first support member 45 and the first elastic member 46 disposed on both sides of the first conductive portion 421 and the first elastic member 46 disposed on both sides of the first conductive portion 422. The abutting piece 47, the third elastic piece 46 and the first abutting piece 47 are all located on the side of the swinging piece 42 away from the first connecting piece 43. The third elastic piece 46 can be but is not limited to a compression spring. The two ends of the third elastic piece 46 respectively abut the inner wall of the swinging piece 42 and the switch housing 41. One end of the first abutting piece 47 is connected to the swinging piece 42, and the other end extends to the outside of the switch housing 41 in a direction away from the first connecting piece 43. The first contact point 4321 and the second contact point 4322 respectively correspond to one end of the first conductive part 421 close to the third elastic piece 46 and one end of the second conductive part 422 close to the third elastic piece 46.

[0073] Specifically, the double-pole double-throw switch 4 also includes a second connecting member 48 arranged inside the switch housing 41 and located on the side of the swinging member 42 close to the first connecting member 43. The first connecting member 43 and the second connecting member 48 are arranged at intervals. The second connecting member 48 is provided with a fifth contact point 481 and a sixth contact point 482 corresponding to one end of the first conductive part 421 close to the first abutting member 47 and one end of the second conductive part 422 close to the first abutting member 47, respectively, that is, the fifth contact point 481 and the sixth contact point 482 are insulated, and the fifth contact point 481 and the sixth contact point 482 are respectively used to electrically connect to the negative and positive poles of the power supply, and the electrical connection is connected through a conductive component, and the conductive component is an electric wire in this embodiment.

[0074] like Fig.12As shown, when the first resisting member 47 is pressed, since the middle portion of the swinging member 42 is rotatably connected to the first supporting member 45, the first resisting member 47 pushes the end of the swinging member 42 close to the first resisting member 47 to move toward the second connecting member 48, and at the same time, the end of the swinging member 42 close to the third elastic member 46 moves toward the direction away from the first connecting member 43, and the third elastic member 46 is in a compressed state. The first conductive portion 421 and the second conductive portion 422 on the swinging member 42 are respectively in contact with the fifth contact point 481 and the sixth contact point 482. At this time, as shown in FIG. Fig.13 As shown, the equivalent circuit between the driving member 3 and the double-pole double-throw switch 4 is in a conductive state, the first electrode is electrically connected to the negative electrode of the power supply via the fifth contact point 481, and the second electrode is electrically connected to the positive electrode of the power supply via the sixth contact point 482, so that the driving member 3 is energized and drives the first clamping arm 11 and the second clamping arm 12 to move away from each other, and the user can remove the electronic device. After removing the electronic device, slowly release the first abutting member 47. Since the third elastic member 46 is in a compressed state, when the first abutting member 47 loses pressure, the end of the swinging member 42 close to the third elastic member 46 moves toward the direction close to the first connecting member 43, and the end of the swinging member 42 close to the first abutting member 47 moves toward the direction away from the second connecting member 48, and the double-pole double-throw switch 4 returns to the positive state. Figure 5 When the electronic device is removed, the tension arm 51 of the dynamic-static contact piece 5 loses the support of the electronic device, and due to the magnetic force between the first magnetic pole 522 of the dynamic arm 52 and the second magnetic pole 542 of the static arm 54, the first magnetic pole 522 and the second magnetic pole 542 are re-adsorbed together, and the dynamic-static contact piece 5 returns to the state of Figure 5 status in .

[0075] In one embodiment of the present invention, Figure 1 As shown, the first clamping arm 11 includes a first clamping plate 111 and a first rack 112 connected to the first clamping plate 111, the second clamping arm 12 includes a second clamping plate 121 and a second rack 122 connected to the second clamping plate 121, the first clamping plate 111 and the second clamping plate 121 are arranged opposite to each other, the first rack 112 and the second rack 122 are arranged opposite to each other, and the smart bracket also includes a transmission assembly 2 connected to the driving member 3, and the transmission assembly 2 is respectively connected to the first rack 112 and the second rack 122.

[0076] Specifically, the driving member 3 is a DC motor, and the transmission assembly 2 includes a worm 21 sleeved on the output shaft of the DC motor, a first reduction gear 22 meshing with the worm 21, a second reduction gear 23 meshing with the first reduction gear 22, and a driven gear 24 meshing with the second reduction gear 23, and the driven gear 24 is respectively meshing with the first rack 112 and the second rack 122, so that the DC motor is controlled to rotate forward or reverse through the double-pole double-throw switch 4 to drive the first clamping arm 11 and the second clamping arm 12 to clamp or release. It can be understood that the transmission assembly 2 of the embodiment of the present invention can also adopt other methods, as long as it can ensure that the driving member 3 drives the first clamping arm 11 and the second clamping arm 12 to clamp or release through the transmission assembly 2, and this embodiment is not limited here.
