Specifically, a part of the guide post 16 extends into the limit groove, and the reliability of the movement of the cover 12 and the base 10 is ensured through the cooperation of the limit groove and the guide post 16.

According to some embodiments of the present application, the guide post 16 is spherical toward one end of the cover 12.

In this embodiment, the end of the guide post 16 facing the cover 12 is spherical to ensure that the upper half of the spring 18 has a certain play.

According to some embodiments of the application, the electronic device accessory further comprises: and a charging part, which is arranged in the base 10 or the cover 12 and is used for supplying power to the electronic equipment.

In this embodiment, the detecting component 3 may also be a distance sensor, specifically, the first distance sensor and the second distance sensor are both used for detecting a distance value between the cover body 12 and the base 10, and when a difference between the distance value detected by the first distance sensor and the distance value detected by the second distance sensor is greater than a distance threshold, it is indicated that one end of the cover body 12 is pressed, and the other end is tilted, so that the action of taking the electronic device by a user is met, and then the control part controls the electromagnet component 2 to be powered off so as to release the adsorption to the electronic device, so that the electronic device is convenient to take.

Further, in the case where the difference between the distance value detected by the first distance sensor and the distance value detected by the second distance sensor is greater than the distance threshold value, the control section determines that the cover 12 is in the taken state.

Thus, in the process of taking the electronic device by the user, the distances between the two ends of the cover body 12 relative to the base 10 are different, and then the distance value detected by the first distance sensor close to the first end of the cover body 12 is different from the distance value detected by the second distance sensor close to the second end of the cover body 12, so that the absolute value of the difference value of the two is greater than the distance threshold value, and the control part controls the electromagnet assembly 2 to be powered off, so that the adsorption effect of the electromagnet assembly 2 on the electronic device is relieved, and the user can conveniently take the electronic device.

In one possible design, the electronic device accessory provided by the application is provided with a small permanent magnet in the cover 12, and a hall sensor in the base 10, and the change of the position and the posture of the cover 12 can influence the distance between the permanent magnet and the hall sensor, and further influence the measured value of the hall sensor. Therefore, the cover 12 can be judged to be in a to-be-used state, a working state or a taking state by the change of the parameter value, and then the on or off of the electromagnet is controlled by the corresponding circuit, so that the adsorption and separation states of the electronic equipment and the electronic equipment accessories are switched. A spring 18 is arranged in the center of the base 10, so that the electronic equipment can be placed for buffering, and the service life is prolonged; after the electronic equipment is taken, the cover body 12 can be jacked up to play a role in resetting.

Specifically, as shown in fig. 4, the magnetic force of the electronic equipment accessory is controlled by an electromagnet, and the whole structure is cuboid. When the electronic equipment accessory is in a state to be used, as shown in fig. 1, the first detecting member 304 (hall sensor) and the second detecting member 322 (hall sensor) are respectively mounted on two sides of the interior of the base 10. A guide post 16 is designed in the middle of the base 10, a spring 18 is installed on the guide post 16, and the upper end of the guide post 16 is spherical so as to ensure that a certain movable space exists in the upper half part of the spring 18. Two cushion blocks 19 are respectively arranged on two sides of the interior of the cover body 12, a first permanent magnet 302 and a second permanent magnet 320 are respectively arranged on the cushion blocks 19 on two sides, and the first permanent magnet 302 and the second permanent magnet 320 respectively correspond to a first detection piece 304 and a second detection piece 322 in horizontal positions. The electromagnet assembly 2 is mounted on the cover 12 and used for adsorbing electronic equipment during operation, and ensuring the stability and alignment during charging. A certain gap exists between the two sides of the base 10 and the cover 12 in the first direction and the second direction, so as to ensure that the cover 12 has a certain movable space in the first direction and the second direction.

The parameter value between the first detecting member 304 and the first permanent magnet 302 is defined as a first parameter value a, and the parameter value between the second detecting member 322 and the second permanent magnet 320 is defined as a second parameter value b. Two trigger thresholds are set separately, namely a second threshold alpha and a first threshold beta, the second threshold is used for comparing the first parameter value and the second parameter value, and the first threshold is used for comparing the difference value between the first parameter value and the second parameter value. And judging the use state of the electronic equipment accessory by judging whether the first parameter value and the second parameter value trigger the first threshold value and the second threshold value or not, wherein the use state is used for controlling the on-off of the electromagnet assembly 2.

When the electronic equipment accessory is in the to-be-used state, the cover 12 is jacked up under the elastic force of the spring 18, the distance between the first permanent magnet 302 and the first detecting member 304, the distance between the second permanent magnet 320 and the second detecting member 322 are far, and the first parameter value a and the second parameter value b are smaller, so that a and b are smaller than a, the cover 12 is in a horizontal state, a is approximately equal to b, and the electromagnet is not electrified.

As shown in fig. 2, when the electronic device is placed on the electronic device accessory, and the electronic device accessory is in an operating state, the cover 12 is pressed down under the action of the gravity of the electronic device, and the spring 18 is compressed, so that the distance between the permanent magnet and the hall sensor is reduced, the first parameter value a and the second parameter value b are increased, and both a and b are larger than α; in the normal use state, the cover body 12 can be in a horizontal state, so a is approximately equal to b, |a-b| < beta, at the moment, the electromagnet is controlled to be electrified, and the electronic equipment is adsorbed on the cover body 12, so that stable charging is ensured.

When the charging is completed and the electronic device needs to be taken out, in this state, as shown in fig. 3, when one side of the electronic device is pressed, the left side of the cover 12 (and vice versa) is pressed down together with the electronic device. Because of the magnetic force between the electronic equipment and the cover body 12, the right side of the cover body 12 is lifted at the same time when the other side of the electronic equipment is lifted, and finally the cover body 12 tilts under the action of force, at the moment, the distance between the first permanent magnet 302 and the first detection piece 304 is reduced, and the value of a is increased; the distance between the second permanent magnet 320 and the second detecting member 322 increases, the value b decreases, a difference exists between the values a and b, |a-b| > beta, and the magnetic force between the electronic device and the cover 12 disappears, so that the electronic device can be easily taken out. When the electronic device is separated, the cover 12 is automatically reset to a state to be used under the action of the spring 18.

The scheme provides a magnetic attraction type electronic equipment accessory structural design scheme convenient for one-hand taking, and the Hall sensor is used for detecting the magnetic field change of the permanent magnet to judge the position and the gesture of the electronic equipment accessory cover body 12, so that the use state of the electronic equipment accessory is judged, the on-off of an electromagnet is controlled, the electronic equipment can be firmly adsorbed by a user when the electronic equipment accessory is used, the magnetic force is eliminated by cutting off a circuit when the electronic equipment accessory is required to be taken, and the purpose that the electronic equipment can be separated from the electronic equipment accessory by one hand is realized. The beneficial effects are as follows:

the application automatically detects the use state of the electronic equipment accessory according to the change of the measured value of the Hall sensor, controls the on-off of the electromagnet, does not need to be manually switched on or off, and is convenient to use. When the electric charging device is used, a user only needs to put the electronic equipment on an electronic equipment accessory when the electric charging device needs to be charged, the electromagnet can be automatically electrified, and the electronic equipment is adsorbed to start charging; when the electronic equipment is taken by a specific action, the electromagnet is automatically powered off, so that a user can easily take the electronic equipment without taking up accessories of the electronic equipment.
