Detailed Description

In order that those skilled in the art will better understand the disclosure, the following detailed description will be given with reference to the accompanying drawings.

Wherein in the description of the embodiments of the present application, "/" indicates an inclusive meaning, for example, a/B may indicate a or B; "and/or" in the text is only an association relationship describing an associated object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In this specification, terms such as "upper, lower, inner, and outer" are established based on positional relationships shown in the drawings, and the corresponding positional relationships may vary depending on the drawings, and therefore, the terms are not to be construed as absolutely limiting the scope of protection; moreover, relational terms such as "first" and "second," and the like, may be used solely to distinguish one element from another element having the same name, without necessarily requiring or implying any actual such relationship or order between such elements.

As shown in fig. 1 and fig. 2, the present embodiment takes a folding mobile phone as an example to describe the provided electronic device, a body of the folding mobile phone is generally divided into two parts, namely a first rotating body 1 and a second rotating body 2, front surfaces of the two parts are covered with a flexible folding screen 3, a back surface of the first rotating body 1 is generally provided with an outer screen, a back surface of the second rotating body 2 is generally provided with a camera, the first rotating body 1 and the second rotating body 2 are connected in the middle through a rotating mechanism 4 and can be folded or unfolded, the rotating mechanism 4 can be designed in the form of a rotating shaft, and the first rotating body 1 and the second rotating body 2 are respectively provided with three magnets 5 at the other sides relative to the rotating mechanism 4, so that the first rotating body 1 and the second rotating body 2 can be attracted together after being folded with each other. When the mobile phone is in a folded state, the mobile phone is similar to a common flat mobile phone in shape, the flexible folding screen 3 is folded between the first rotating body 1 and the second rotating body 2, at the moment, the mobile phone can be operated through the outer screen arranged on the back surface of the first rotating body 1, when the mobile phone is in an unfolded state, the flexible folding screen 3 serving as the inner screen is completely unfolded, and the area of a display area is enlarged and is about twice of that of the outer screen.

For the consumer, when using the folding mobile phone, although the folding mobile phone can be opened by various hand motions, the applicant has found in research that the most common opening position is always located at the middle-lower part of the folding mobile phone, that is, in practical use, the probability of opening the folding mobile phone by applying force from the middle-lower part of the folding mobile phone is high, and the probability of opening the folding mobile phone by applying force from other positions is low. Moreover, during the opening process, the first and second

rotating bodies

1, 2 do not spread out in an absolutely rigid manner, but have a slight deformation. This characteristic makes the gap between the first rotor 1 and the second rotor 2 uneven in the initial stage of opening of the folding phone, and if the upper part of the phone is opened, the upper part is separated first and then the lower part is separated, and if the lower part of the phone is opened, the lower part is separated first and then the upper part is separated, and the applied force generates a moment in the longitudinal direction in addition to a moment in the lateral direction with respect to the rotating mechanism 4.

The practical use habits found by the above studies and the slight deformation of the folded handset during unfolding have been neglected in the previous designs and have not received sufficient attention.

Based on the above research and findings, the present embodiment redesigns the magnetic attraction structure of the folding mobile phone.

As shown in fig. 3, in order to ensure the closing effect of the whole mobile phone, the sum of the magnetic forces of all the magnets 5 is unchanged, that is, F1+ F2+ F3= C, where C is the total magnetic force, and the value thereof is generally between 0.5N and 20N, and under the condition that the total magnetic force C is unchanged, by designing the distribution and the magnetic force of the magnets, the total moment that the upper magnet can generate relative to the moment reference line 6 is greater than the total moment that the lower magnet can generate relative to the moment reference line 6, the force value required by a consumer to open the mobile phone in the lower half area can be reduced from 5.55N to 3.7N, and the use experience is optimized.

As shown in fig. 7, the present embodiment provides a fifth electronic device, and the same parts of the electronic device as those of the first electronic device are given the same reference numerals, and the same description is omitted.

Specifically, the first rotating body 1 and the second rotating body 2 are respectively provided with five magnets 5, and the five magnets 5 are sequentially arranged from top to bottom, wherein three magnets 5 are upper magnets, and two magnets 5 are lower magnets.

The three upper magnets are respectively a third magnet 5-3, a fourth magnet 5-4 and a fifth magnet 5-5, and the distances between the third magnet 5-3, the fourth magnet 5-4 and the fifth magnet 5-5 and the moment reference line 6 are sequentially increased.

(L/2-X1)F1+(L/2-X2)F2+(L/2-X3)F3＜ (X4-L/2)F4+(X5-L/2)F5

In the above embodiment, the plurality of magnets 5 are distributed so as to be positioned in the same column, but in another embodiment shown in fig. 9, the plurality of magnets 5 may not be positioned in the same column, that is, the plurality of magnets 5 may be appropriately shifted in the lateral direction when being distributed, and since the distance between each magnet 5 and the moment reference line 6 is kept constant after the lateral shift, the condition defined by the formula in each of the above embodiments can still be satisfied.

In other embodiments, the magnetic force of the upper magnet close to the moment reference line 6 can be further designed to be larger than that of the upper magnet far away from the moment reference line 6; and/or the magnetic force of the lower magnet close to the moment reference line 6 is designed to be larger than the magnetic force of the lower magnet far from the moment reference line 6, that is, the closer to the moment reference line 6, the larger the magnetic force of the magnet 5.

In this way, by more finely distributing the magnetic force of the upper magnet and/or the lower magnet, the magnetic force of the magnet 5 close to the moment reference line 6 is larger, and the magnetic force of the magnet 5 far from the moment reference line 6 is smaller, so that the opening device can be adapted to the opening of a consumer from the lower part, and the consumer can have good use experience even when the opening device is accidentally opened from the upper part or opened from both the upper part and the lower part, thereby maximally taking into account various possible opening methods.

The electronic device provided by the embodiment of the application has a redesigned magnetic attraction structure, and the magnetic attraction structure does not simply adjust the magnetic force of the upper and lower magnets, and does not simply exchange the positions of the upper and lower magnets in the conventional magnetic attraction structure, but on the basis of fully researching the product characteristics, finds that the opening positions commonly used by consumers in practice are the middle and lower parts of the first rotating body 1 and the second rotating body 2, and the first rotating body 1 and the second rotating body 2 are not absolutely rigidly unfolded, but slightly deformed in the opening and closing process.

As shown in fig. 10 to 13, no matter the consumer opens the folding cellular phone with one hand or both hands, the hand feeling of resistance is mainly concentrated on the initial stage, and after the gap between the first rotating body 1 and the second rotating body 2 exceeds the range of the attraction force of the magnet 5, the hand feeling disappears instantly and the hand is unfolded easily.

When a consumer opens the folding mobile phone in a one-hand mode, the first rotating body 1 or the second rotating body 2 is buckled outwards mainly by the force of a thumb, and then the mobile phone is opened.

When a consumer opens the foldable mobile phone with two hands, the left hand and the right hand hold the mobile phone at the same time, the left hand is on the upper side, the right hand is on the lower side, or the right hand is on the upper side, the left hand is on the lower side, the upper hand mainly plays a role in fixing, and then the first rotating body 1 or the second rotating body 2 is rotated by the lower hand, so that the mobile phone is opened.

Therefore, the electronic equipment provided by the embodiment of the application designs a brand-new magnetic attraction structure in a targeted manner, the magnetic attraction structure takes the central line perpendicular to the rotating shaft as the moment reference line 6, the total moment relation of the upper magnet and the lower magnet in the vertical direction is established, and the total moment in the direction is determined by the number of the magnets, the magnetic force, the installation position of the magnetic attraction part and other factors, so that the opening force actually required by a consumer can be reduced under the condition that the total magnetic force is unchanged through the close connection and the synergistic effect among the factors, the use experience of the consumer is effectively improved, the effective closing of the electronic equipment can be ensured, the electronic equipment can be opened easily, and the product quality of the folding electronic equipment can be remarkably improved.
