And a rechargeable battery can be arranged in the bracket to supply power to the wireless charging module 100 and the electromagnet 42, and the power can also be directly supplied by the power supply interface 110.
The working principle of the bracket is as follows: first, when the elastic element 70 is a compression spring, the stent is initially in an open state; when the elastic element 70 is a tension spring, the bracket is in a closed state initially; when the elastic element 70 is a torsion spring, the stand is initially in a closed state, and the elastic element 70 is used as a compression spring for explanation below (the other two situations are opposite, the common point is that the electromagnet 42 is used for attracting and driving the left clamping arm 20 or the right clamping arm 30 to slide), and when the mobile phone is not placed in the stand, the stand is in an open state under the action of the elastic element 70; after the mobile phone is placed in the support, the microswitch 90 is triggered, the controller 50 receives a signal to control the electromagnet 42 to be electrified, the electromagnet 42 generates an adsorption force on a magnet or an iron core on the left clamping arm 20 or the right clamping arm 30, so that the left clamping arm 20 or the right clamping arm 30 is pulled (the resistance of an elastic element is overcome), and the left clamping arm and the right clamping arm are linked and folded to clamp the mobile phone; when the mobile phone is taken out, the inductive switch or the button switch is triggered, the controller 50 receives a signal to control the electromagnet 42 to be powered off, the electromagnet 42 loses magnetic force, the left clamping arm and the right clamping arm are reset and opened under the action of the elastic element 70, and the mobile phone can be taken out. It should be noted that, when the elastic element 70 is a torsion spring or a tension spring, the inductive switch or the push-button switch is triggered, and after the electromagnet 42 is powered on, the magnetic force of the electromagnet itself generates an adsorption force on the magnet or the iron core on the left clamping arm 20 or the right clamping arm 30, so as to pull (overcome the resistance of the elastic element) the left clamping arm 20 or the right clamping arm 30, and the left and right clamping arms are linked with the opening of the bracket; after the mobile phone is placed in the clamping device, the controller 50 controls the electromagnet 42 to be powered off when the micro switch 90 is touched, and the left clamping arm and the right clamping arm are automatically folded to clamp the mobile phone.
It should be noted that the magnet or the iron core 60, especially the magnetic force of the magnet is smaller than the driving force of the elastic element 70, that is, after the electromagnet 42 is de-energized, the attraction force of the magnet to the electromagnet 42 does not affect the reset of the elastic element 70.
The design of the utility model is characterized in that the sliding of the left and right clamping arms is realized by adopting the adsorption characteristic of the electromagnet to the magnet or the iron core in the bracket and combining the linkage structure of the gear and the left and right clamping arms; and the electromagnet or the iron core is loosened by utilizing the power failure of the electromagnet, and the elastic element drives the left and right clamping arms to reset. The support is simple in overall structure, convenient and fast to operate, automatic clamping or loosening of the support is achieved, and convenience is provided for users.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
