To better understand the above technical solutions, the technical solutions will be described in detail in conjunction with the accompanying drawings and the specific implementing modes below.
First Embodiment
As shown in FIGS. 1, 2, and 3, a method for controlling electronic apparatus, being applied to an electronic apparatus including a first body 201, a second body 202 on which a touch display unit 204 is provided, and a rotary shaft 203 used to connect the first body 201 and the second body 202 and through which the second body 202 can rotate relative to the first body 201, the method including:
executing step 101, i.e., determining whether the electronic apparatus is under a predetermined condition, so as to obtain a determination result; and
executing step 102 after step 101 is completed, i.e., when the determination result indicates that the electronic apparatus is under the predetermined condition, increasing the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft, so as to cause the second body 202 to reside in a non-rotational state relative to the first body 201 when a user is touching the touch display unit 204.
In a specific implementation, as shown in FIG. 2, the electronic apparatus may be a notebook computer with a touch display screen, in this case, the first body 201 is a host portion of the notebook computer (the host portion includes a notebook keyboard, a mouse touchpad, and main hardware of the notebook computer, wherein the main hardware further includes motherboard, CPU, video card, network card, memory, hard drives, etc.), the second body 202 is a display portion of the notebook computer (the touch display unit 204 is embedded within the display portion). The touch display unit 204 may specifically be a capacitive touch display screen.
In a specific implementation, as shown in FIG. 2, the electronic apparatus may also be a tablet computer assembly, which includes a tablet computer and a keyboard base, in this case, the first body 201 is the keyboard base, the second body 202 is the tablet PC, and a touch display screen 204 is embedded within the second body 202, and the first body 201 can rotate about the second body 202. The tablet assembly can have multiple types of connection mode, in FIG. 2, the tablet computer (i.e., the second body 202) is connected with the keyboard base (i.e., the first body 201) by a “first connection mode”, in this case, when the first angle between the first body 201 and the second body 202 is zero degrees (i.e., the tablet computer and the keyboard base are in a folded state), the touch display screen of the tablet computer faces the keyboard of the keyboard base. In FIG. 3, the tablet computer (i.e., the second body 202) is connected the keyboard base (i.e., the first body 201) by a “second connection mode”, in this case, when the first angle between the first body 201 and the second body 202 is zero degrees (i.e., the tablet computer and the keyboard base are in a folded state), the touch display screen of the tablet computer has its back towards the keyboard of the keyboard base.
As for what type of electronic apparatus the electronic apparatus is, the embodiment of the present application makes no specific limitation thereto.
In the prior art, when the user is touching the touch display unit 204, the second body 202 is apt to rotate relative to the first body 201, so that the user cannot use the electronic apparatus normally. In the embodiment of the present application, by means of increasing resistance rotation that the rotary shaft 203 experiences during rotation of the rotary shaft when the electronic apparatus is under a predetermined condition, so that the first body 201 and second body 202 are in the non-rotational state, at this time, if the user uses the touch display unit 204 to operate, the second body 202 cannot rotate relative to the first body 201, so that the technical problem that when the user is using the touch display unit, the second body 202 and the first body 201 are apt to rotate is solved.
Furthermore, in order to implement increasing resistance rotation that the rotary shaft 203 experiences during rotation of the rotary shaft, the embodiment of the present application discloses an engagement module.
As shown in FIG. 4, the electronic apparatus further includes
an engagement module, which specifically includes:
a gear 303 connected to the rotary shaft 203;
an electromagnet 301 fixed to the first body 201; and
a movable slot 302 provided on the first body 201,
wherein the movable slot 302 can move to a position where the gear 303 is located under an action of magnetic force of the electromagnet 301, and engage with the gear 303, thereby increases a rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft.
In a specific implementation, an end of the movable slot 302 close to the electromagnet 301 has a first magnetism, and the slot movable 302 may be extended freely under an action of the electromagnet 301. For example, when the first magnetism is an S pole, by applying a current A1 to the electromagnet, so that an end of the electromagnet 301 close to the movable slot 302 generates an N pole magnetism, because of “opposite poles attract”, so the electromagnet 301 can magnetize the movable slot 302 to cause the movable slot 302 to retract; by applying a current A2 (the current A2 has a direction opposite to that of the current A1) to the electromagnet, so that an end of the electromagnet 301 close to the movable slot 302 also generates an S pole magnetism, because of “like poles repel”, so that the electromagnet 301 can repel the movable slot 302, to cause the movable slot 302 to extend outwards, and engage with the gear 303, thereby increases the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft.
In a specific implementation, the movable slot 302 and the gear 303 may be made of plastic, metal, rubber, and other materials, the embodiment of the present application makes no specific limitation to the materials of the movable slot 302 and the gear 303.
In the embodiment of the present application, by increasing the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft, it is achieved that when the user is touching the touch display unit 204, the first body 201 and second body 202 will not rotate. In a specific implementation, under the premise of ensuring that the first body 201 and second body 202 will not rotate when the user is touching the touch display unit 204, the movable slot 302 and the gear 303 can be “fully engaged” or “not fully engaged”, if they are “fully engaged”, no matter how strong a force the user acts on the second body 202, the first body 201 and the second the body 202 will not rotate; if they are “not fully engaged”, that is, when the force that the user acts on the second body 202 is strong enough, the second body 202 can still rotate relative to the first body 201. Herein it should be noted that the force that causes the second body 202 to rotate relative to the first body 201 is significantly stronger than the force acting on the touch display unit 204 when the user is using touch display unit 204 normally.
In a specific implementation, steps 101 and 102 specifically have the following two implementation modes.
First Mode
When the predetermined condition specifically is that a user is touching the touch display unit 204, step 101 specifically is:
determining, through the touch display unit 204, whether the user is touching the touch display unit 204, so as to obtain a first determination result.
In a specific implementation, determining, through the touch display unit 204, whether the user is touching the touch display unit 204 is determining that the user is using the touch display unit 204 to operate the display apparatus.
Furthermore, step 102 specifically is:
when the first determination result indicates that the user is touching the touch display unit 204, applying a first current to the electromagnet 301, causing the electromagnet 301 to generate magnetic force on the movable slot 302, so that the movable slot 302 moves towards a position where the gear 303 is located, and engages with the gear 303, thereby increases the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft.
In a specific implementation, when it is confirmed that the user is using the touch display unit 204 to operate the electronic apparatus, a current is applied to the electromagnet 301, so that the electromagnet 301 can repel the movable slot 302, cause the movable slot 302 to engage with the gear 303, thereby increase the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft, so that the second body 202 is in a non-rotational state relative to the first body 201, and thereby a notebook computer with a touch display screen in the prior art has a technical problem that when a user touches the touch display screen, the touch display screen is apt to rotate against a keyboard base is solved.
Second Mode
The first body and the second body are two detachable bodies, the second body 202 can be detached from the first body 201, and a connection mode between the second body 202 and the first body 201 has a “first connection mode” and a “second connection mode” different from the first connection mode, wherein the first body 201 includes a first front plane within which a keyboard is embedded, and the second body 202 includes a second front plane within which the touch display unit 204 is embedded.
As shown in FIG. 2, the first connection mode is a connection mode in which the second front plane can face the first front plane when a first angle value of a first angle between the second body 202 and the first body 201 is zero degrees;
As shown in FIG. 3, the second connection mode is a connection mode in which the second front plane can have its back towards the first front plane when the first angle value of a first angle between the second body 202 and the first body 201 is zero degrees.
In a specific implementation, as shown in FIGS. 2 and 3, the electronic apparatus may also be a tablet computer assembly, which includes a tablet computer and a keyboard base, in this case, the keyboard base is the first body 201, the tablet PC is the second body 202, and the first body 201 and the second body 202 are connected via a rotary shaft 203, meanwhile the first body 201 and the second body 202 have two different connection modes, that is, the “first connection mode” and the “second connection mode”.
As shown in FIG. 2, which is an effect diagram after the first body 201 and the second body 202 are connected based on the “first connection mode”, thus it can be seen that, in this case, the second body 202 is “front inserted” in the first body 201, the plane having the touch display screen of the second body 202 (i.e., the first front plane) faces the plane having the keyboard of the first body 201 (i.e., the second front plane).
As shown in FIG. 3, which is an effect diagram after the first body 201 and the second body 202 are connected based on the “second connection mode”, thus it can be seen that, in this case, the second body 202 is “back inserted” in the first body 201, the plane having the touch display screen of the second body 202 (i.e., the first front plane) has its back towards the plane having the keyboard of the first body 201 (i.e., the second front plane).
In a specific implementation, the rotary shaft 203 is fixed to the first body 201, and a groove is provided on the rotary shaft 203, so that the second body 202 can be inserted and fixed in the groove, so as to achieve the purpose of being connected with the first body 201.
In a specific implementation, the electronic apparatus can recognize that the connection mode between the first body 201 and the second body 202 is the “first connection mode” or the “second connection mode” in particular, its implementation process is as follows.
Two contact points are set on a side for inserting the groove of the second body 202, i.e., contact point pin_a1 and contact point pin_a2, and two contact points are provided in the groove, i.e., contact point pin_b1 and contact point pin_b2. When the second body 202 is connected to the first body 201 by the “first connection mode”, the contact point pin_a1 and the contact point pin_b1 contact, and the contact point pin_a2 and the touch point pin_b2 contact, when the electronic apparatus detects that the contact point pin_a1 and the contact point pin_b1 contact, and the contact point pin_a2 and the touch point pin_b2 contact, it recognizes that the connection mode between the first body 201 and the second body 202 is the “first connection mode”. When the second body 202 is connected to the first body 201 by the “second connection mode”, the contact point pin_a1 and the contact point pin_b2 contact, and the contact point pin_a2 and the touch point pin_b1 contact, when the electronic apparatus detects that the contact point pin_a1 and the contact point pin_b2 contact, and the contact point pin_a2 and the touch point pin_b1 contact, it recognizes that the connection mode between the first body 201 and the second body 202 is the “second connection mode”.
Hereinafter, cases A and B will be classified and introduced according to the different connection modes.
Case A
When the connection mode is the “first connection mode”, and the predetermined condition specifically is that the first angle value is larger than a first predetermined angle value, step 101 specifically includes:
acquiring the first angle value; and
determining whether the first angle value is larger than the first predetermined angle value, so as to obtain a second determination result.
In a specific implementation, the first angle value may be acquired through an angle detection device (e.g., a gyro). The value range of the first predetermined angle value is: 105 to 135 degrees, such as 105 degrees, or 115 degrees, or 125 degrees, or 135 degrees.
Based on the user's habits, when the first body 201 and the second body 202 are connected in the “first connection mode”, an optimum angle of the first angle that the user uses the touch display unit 204 is greater than 105 degrees, so in this case, the range of the first predetermined angle is determined as 105 to 135 degrees.
Furthermore, step 102 specifically is:
when the second determination result indicates that the first angle value is larger than the first predetermined angle value, applying a first current to the electromagnet 301, causing the electromagnet 301 to generate the magnetic force on the movable slot 302, so that the movable slot 302 moves towards a position where the gear 303 is located, and engages with the gear 303, thereby increases the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft.
Case B
When the connection mode is the “second connection mode”, and the predetermined condition specifically is that the first angle value is smaller than a second predetermined angle value, step 101 specifically includes:
acquiring the first angle value; and
determining whether the first angle value is smaller than the second predetermined angle value, so as to obtain a third determination result.
In a specific implementation, the first angle value may be acquired through an angle detection device (e.g., a gyro). The value range of the first predetermined angle value is: 45 to 75 degrees, such as 45 degrees, or 55 degrees, or 65 degrees, or 75 degrees.
Based on the user's habits, when the first body 201 and the second body 202 are connected in the “second connection mode”, an optimum angle of the first angle that the user uses the touch display unit 204 is less than 75 degrees, so in this case, the range of the first predetermined angle is determined as 45 to 75 degrees.
Furthermore, step 102 specifically is:
when the third determination result indicates that the first angle value is smaller than the second predetermined angle value, applying a first current to the electromagnet 301, causing the electromagnet 301 to generate the magnetic force on the movable slot 302, so that the movable slot 302 moves towards a position where the gear 303 is located, and engages with the gear 303, thereby increases the rotation resistance that the rotary shaft 203 experiences during rotation of the rotary shaft.
Based on the same inventive concept, another embodiment of the present application provides an electronic apparatus that implements the method for processing information in the embodiment of the present application.

Furthermore, the electronic apparatus further includes:
an engagement module, which specifically includes:
a gear 303 connected to the rotary shaft 203;
