Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

The full-face screen is the development trend of the mobile terminal. The difficulty in realizing the full-screen is how to cancel or hide devices such as a front-facing camera, a distance sensor, a microphone, a fingerprint sensor, a physical key and the like on the front face of the terminal, so that the proportion of the display screen is increased as much as possible.

Fig. 1 schematically illustrates an external view of a slide type terminal 100 according to an exemplary embodiment of the present disclosure. The slide type terminal 100 includes: the upper sliding cover 120 and the lower sliding cover 140 are connected by a sliding rail. The upper slide cover 120 and the lower slide cover 140 can be switched between a slide-open state and a closed state.

The slide-open state refers to a state in which a relative sliding distance between the upper slide cover 120 and the lower slide cover 140 is greater than a preset value. In the slide-open state, the front camera 12 on the front surface of the lower slide cover 140 is exposed.

The closed state is a state in which the relative sliding distance between upper sliding cover 120 and lower sliding cover 140 is zero, that is, the front positions of upper sliding cover 102 and lower sliding cover 140 are coincident. In the closed state, the front camera 12 on the front surface of the lower slide cover 140 is in an unexposed state.

Optionally, a slide detection assembly and a slide-assist assembly are disposed between the upper slide cover 120 and the lower slide cover 140.

On one hand, the sliding detection component is configured to detect whether a relative sliding distance between the upper sliding cover 102 and the lower sliding cover 140 along a sliding direction reaches a threshold value when a user starts to slide the upper sliding cover and the lower sliding cover, and report a sliding event of the sliding cover when the relative sliding distance reaches the threshold value. The sliding-cover sliding-assistant component is used for controlling the upper sliding cover 120 and the lower sliding cover 140 to automatically slide when the sliding-cover slides open according to the sliding-cover sliding event until the sliding-cover sliding-assistant component is completely switched to the sliding-open state from the closed state.

On the other hand, the sliding detection component is configured to detect whether a relative sliding distance between the upper sliding cover 102 and the lower sliding cover 140 along the sliding direction reaches a threshold value when the user starts to slide the upper sliding cover and the lower sliding cover, and report a sliding cover closing event when the relative sliding distance reaches the threshold value. The sliding cover sliding-assistant assembly is used for controlling the upper sliding cover 120 and the lower sliding cover 140 to automatically slide when the sliding cover is closed according to the sliding event until the sliding state is completely switched to the closed state.

The above-described slip detection assembly may be implemented by one magnet and two hall sensors. The hall sensor is an electronic device that generates an output voltage by a hall effect, which means that when a current passes through a hall semiconductor located in a magnetic field from one end to the other end, electrons in the current are shifted in a lateral direction of the hall semiconductor by a lorentz force, so that the hall semiconductor generates a potential difference. The potential difference generated by the Hall semiconductor through the Hall effect is the Hall voltage.

Fig. 2 shows a schematic structural diagram of a slide type terminal 100 according to another exemplary embodiment of the present application. The slide type terminal 100 includes: an upper slide cover 120 and a lower slide cover 140.

The upper sliding cover 120 and the lower sliding cover 140 are connected by a sliding rail (not shown).

A magnet 122 is disposed within the upper slider 120. Optionally, the magnet comprises a first pole and a second pole. In this embodiment, the first magnetic pole is an N pole, the second magnetic pole is an S pole, and the magnetic force lines of the magnet are oriented from the N pole to the S pole. Optionally, the front surface of the upper sliding cover 120 is further provided with a touch screen, and the screen occupation ratio of the touch screen is greater than a preset screen occupation ratio, for example, the screen occupation ratio of the touch screen is greater than 90%.

The lower sliding cover 140 is provided with a first hall sensor 142, a second hall sensor 144 and a processor 146, and the first hall sensor 142 and the second hall sensor 144 are electrically connected with the processor 146 respectively. Optionally, the processor 146 is also connected to a memory 148. Optionally, the first hall sensor 142 and the second hall sensor 144 are respectively connected to a GPIO (General Purpose Input/Output) interface of the processor 146. Optionally, the first hall sensor 142 and the second hall sensor 144 are respectively connected to a GPIO (General Purpose Input/Output) interface of the processor 146. Optionally, at least one of a motion sensor, a front camera, a rear camera, a communication chip, a physical interface, a microphone, a speaker, and an antenna is further disposed in the lower sliding cover 140.

The first and

second hall sensors

142 and 144 are disposed at a preset distance d in the sliding direction of the upper and lower sliding covers. The preset distance d may be determined by a developer according to the total sliding length L of the upper and lower sliding covers, and the preset distance d is a distance less than L. Optionally, the midpoint of the preset distance d coincides with the midpoint of the total sliding length L.

In the state where the slide cover is slid open, the first hall sensor 142 and the second hall sensor 144 are both located on one side in the direction of the first magnetic pole of the magnet 122. Optionally, the first magnetic pole is an N-pole. One side of the direction of the first magnetic pole does not include the position right below the first magnetic pole.

In the closed state of the slide cover, the first hall sensor 142 and the second hall sensor are both located on one side of the magnet 122 in the direction of the second magnetic pole. Optionally, the second magnetic pole is an S-pole. One side in the direction of the second magnetic pole does not include the position right below the second magnetic pole.

Alternatively, when the direction of the magnetic flux line component in the vertical direction in the drawing is changed, the output level is also changed.

In a scenario where the magnet 122 is not interfered by other magnetic fields, that is, in a normal operation mode of the slide detection assembly:

fig. 3 is a schematic diagram illustrating a level change of the slide type terminal 100 shown in fig. 2 during a sliding process.

In the closed state 31, the first hall sensor 142 and the second hall sensor 144 are both located on one side of the direction of the N pole of the magnet 122, the first hall sensor 142 is close to the magnet 122, the magnetic line of force of the magnet 122 from top to bottom passes through the first hall sensor 142, at this time, the output level of the first hall sensor 142 is a first level 0, and the first level 0 may be a low level; the second hall sensor 144 is farther from the magnet 122 and less influenced by the magnet 122, and the output level of the second hall sensor 144 is the second level 1, and the second level 1 may be a high level. That is, in the closed state, the output levels of the first and

second hall sensors

142 and 144 are 01.

When the magnet 122 slides to a position right above the first hall sensor 142, the magnetic line component in the vertical direction received by the first hall sensor 142 becomes 0, and the magnetic line component in the horizontal direction is not 0; when the magnet 122 continues to slide in the sliding direction, the vertical magnetic flux component received by the first hall sensor 142 changes from bottom to top. At this time, the output level of the first hall sensor 142 changes from the first level 0 to the second level 1.

In the intermediate state 32, the output levels of the first hall sensor 142 and the second hall sensor 144 are 11.

When the magnet 122 slides to a position right above the second hall sensor 144, the magnetic line component in the vertical direction received by the second hall sensor 144 becomes 0, and the magnetic line component in the horizontal direction is not 0; when the magnet 122 continues to slide in the slide-off direction, the vertical magnetic flux component received by the second hall sensor 144 changes from top to bottom. At this time, the output level of the second hall sensor 144 changes from the second level 1 to the first level 0.

In the slide-off state 32, the output levels of the first and

second hall sensors

142 and 144 are 10.

That is, when the upper and

lower sliders

120 and 140 are relatively slid in the slide-open direction, the output levels of the first and

second hall sensors

142 and 144 are shifted in the sequence of 01 → 11 → 10, and the program code executed by the processor 146 generates and outputs a slide-open event at an output level of 10. The sliding cover slide-open event can be output to an operating system and an application layer located at an upper layer. When the operating system receives the sliding event, the sliding assisting assembly can be controlled to drive the upper sliding cover 120 and the lower sliding cover 140 to automatically slide until the sliding event is completely in the sliding state.

Conversely, when the upper and

lower sliders

120 and 140 are relatively slid in the closing direction, the output levels of the first and

second hall sensors

142 and 144 transition in the order of 10 → 11 → 01, and the program code executed by the processor 146 generates and outputs a slider closing event when the output level is 01. The sliding closure event may be output to an operating system and an application layer located at an upper layer. When the operating system receives the sliding closure event, the sliding closure sliding assistance assembly may be controlled to drive the upper sliding closure 120 and the lower sliding closure 140 to automatically slide until the sliding closure is completely closed.

In summary, the slide-type terminal provided in this embodiment implements detection of the slide state by using two hall sensors and one magnet, and can implement approximately the same judgment logic in both the sliding-open direction and the sliding-close direction.

Meanwhile, when the center point of the preset distance d is coincident with the center point of the maximum sliding process, due to the symmetry of the first Hall sensor and the second Hall sensor in the sliding process, sliding closure state events are generated in two sliding directions at almost the same triggering distance, and the consistency of user experience is ensured.

However, the inventor found that, in the process of manufacturing the sliding-type terminal 100, since other electronic components that are easily magnetized exist in the sliding-type terminal 100, for example, the USB control board needs to be connected to the main board through a flexible flat cable, an elongated thin steel sheet exists on the plug-in component of the flexible flat cable, and the thin steel sheet is influenced by an external magnetic field in the manufacturing process, and has a certain probability (for example, 3%) of being magnetized. The magnetized thin steel sheet can affect the normal operation of the Hall sensor.

Fig. 4 shows a schematic position of the disturbing magnetic member 160. The disturbing magnetic member 160 is located near the first hall sensor 142, and assuming that it is disturbed by an external magnetic field during the manufacturing process, the magnetic pole direction of the disturbing magnetic member 160 is the same as the magnetic pole direction of the magnet 122, so that the magnetic line component of the magnetic lines of force generated by the disturbing magnetic member 160 in the vertical direction is from top to bottom with respect to the first hall sensor 142.

Fig. 5 is a schematic diagram illustrating a level change of the slide type terminal 100 shown in fig. 4 during a sliding process when magnetization of the interference magnetic member is weak.

In the closed state 31, the first hall sensor 142 and the second hall sensor 144 are both located on one side of the direction of the N pole of the magnet 122, the first hall sensor 142 is close to the magnet 122, the magnetic line of force of the magnet 122 from top to bottom passes through the first hall sensor 142, and meanwhile, the magnetic line of force component of the interference magnetic component 160 from top to bottom also passes through the first hall sensor 142, that is, the sum of the magnetic line of force components of the first hall sensor 142 in the vertical direction is from top to bottom, at this time, the output level of the first hall sensor 142 is a first level 0, and the first level 0 may be a low level; the second hall sensor 144 is farther from the magnet 122 and the interfering magnetic member 160, and is less affected by the magnet 122, and the output level of the second hall sensor 144 is a second level 1, which may be a high level. That is, in the closed state, the output levels of the first and

second hall sensors

142 and 144 are 01.

When the magnet 122 slides to a position directly above the first hall sensor 142, the magnetic line component of the magnet 122 to the first hall sensor 142 in the vertical direction becomes 0, but the magnetic line component of the interfering magnetic member 160 in the vertical direction is not 0 (still from top to bottom), and the output level of the first hall sensor 142 is 0. When the magnet 122 continues to move to the right for a distance, the magnetic line component of the magnet 122 to the first hall sensor 142 in the vertical direction changes from bottom to top, the sum of the magnetic line component of the magnet 122 to the magnetic interference component 160 in the vertical direction is offset to 0, and the output level of the first hall sensor 142 changes from the first level 0 to the second level 1.

In the intermediate state 32a, the output levels of the first hall sensor 142 and the second hall sensor 144 are 11.

When the magnet 122 continues to slide rightward, the sum of the magnetic line components of the magnet 122 and the interfering magnetic member 160 in the vertical direction to the second hall sensor 122 is cancelled to 0, resulting in the output level of the second hall sensor 143 changing from the second level 1 to the first level 0.

In the intermediate state 32c, the output levels of the first and

second hall sensors

142 and 144 are 10.

When the magnet 122 continues to slide, although the magnet 122 has moved away from the first hall sensor 142, the first hall sensor 142 still receives the magnetic flux line component from top to bottom interfering with the magnetic member 160 in the vertical direction, and the output level of the first hall sensor 142 changes from the second level 1 to the first level 0.

In the slide-open state 32, the output levels of the first hall sensor 142 and the second hall sensor 144 are 00.

That is, when the upper and

lower sliders

second hall sensors

142 and 144 transition in the order of 01 → 11 → 10 → 00. Unlike the normal detection process, a processing error of the processor may be caused.

The embodiment of the present application is intended to provide a magnetization manner, which is used to purposefully magnetize the interfering magnetic component 160 during the manufacturing process, so that the magnetic field of the interfering magnetic component 160 will not interfere with the normal operation of the dual hall sensor.

According to the physical characteristics of the magnetic material, the residual magnetic induction when the external magnetic field is 0 after the magnetic material is saturated is called the residual magnetic induction B_r. However, the permanent magnet is located in a magnetic circuit with a gap, and thus the magnetic circuit is in an open state. In this case, the working point of the permanent magnet is changed from B under the action of the demagnetizing field_rMoveBy point D, the permanent magnet exhibits a remanence no longer B_rAnd is B_d. On the demagnetization curve, a linear straight line of the permanent magnet working point D and the coordinate origin O becomes an open-circuit magnet wire, and the slope of OM is called as the magnetic permeability coefficient mu₀. T is called a demagnetization factor, and T is related to the shape of the permanent magnet, causing M to be a physical quantity determined by the shape of the permanent magnet.

The magnetized steel sheet is a very thin rectangular steel sheet, and the height H of the rectangular steel sheet is_dDue to H_dEven if the magnet is taken down to magnetize the rectangular steel sheet in the thickness direction, M is 0 because T is 1, and B is known from the formula_dWhen the value is 0, the remanence is almost 0, and the magnetic induction Br is small although it is also called a permanent magnet. Even if the small rectangular steel sheet is magnetized, if the rectangular steel sheet is magnetized in the length direction, M is larger because T is small, and B is larger because T is small_dAlso relatively large and therefore still permanent magnets. The rectangular steel sheet can be magnetized along the length direction.

Fig. 6 shows a block diagram of a slide type terminal 100 according to an exemplary embodiment of the present application. The lower slider 140 of the slider-type terminal 100 further includes an interference magnetic member 160 therein, and the interference magnetic member 160 is located on the peripheral side of the first hall sensor 142.

In the closed state of the slide cover, the magnet 122 and the interfering magnetic member 160 generate magnetic flux components in opposite directions on the vertical plane at the first hall sensor. Illustratively, the magnet 122 generates a magnetic flux component from top to bottom in the vertical direction of the first hall sensor 142, and the interference magnetic member 160 generates a magnetic flux component from bottom to top in the vertical direction of the first hall sensor 142.

Optionally, in a closed state of the sliding cover, the magnet generates a first magnetic force line component on a vertical plane at the first hall sensor, and the interfering magnetic component generates a second magnetic force line component on the vertical plane at the first hall sensor, where the first magnetic force line component is greater than the second magnetic force line component. The vertical plane is a plane perpendicular to the sliding direction.

Fig. 7 is a schematic diagram illustrating a level change of the slide type terminal 100 shown in fig. 6 during a sliding process.

In the closed state 71, the first hall sensor 142 and the second hall sensor 144 are both located on one side of the direction of the N pole of the magnet 122, the first hall sensor 142 is closer to the magnet 122, a first magnetic line component of the magnet 122 from top to bottom passes through the first hall sensor 142, and a second magnetic line component of the interference magnetic component 160 from bottom to top also passes through the first hall sensor 142, although the first and second magnetic line components cancel out a part of the magnetic line component, the first magnetic line component is greater than the second magnetic line component, that is, the sum of the magnetic line components of the first hall sensor 142 in the vertical direction is from top to bottom, at this time, the output level of the first hall sensor 142 is a first level 0, and the first level 0 may be a low level; the second hall sensor 144 is farther from the magnet 122 and the interfering magnetic member 160, and is less affected by the magnet 122, and the output level of the second hall sensor 144 is a second level 1, which may be a high level. That is, in the closed state, the output levels of the first and

second hall sensors

142 and 144 are 01.

When the magnet 122 does not slide right above the first hall sensor 142, the first magnetic flux component of the magnet 122 to the first hall sensor 142 in the vertical direction gradually becomes smaller, but the second magnetic flux component of the interfering magnetic member 160 in the vertical direction remains unchanged, and when the sum of the magnetic flux components of the two is 0, the output level of the first hall sensor 142 changes from the first level 0 to the second level 1.

In the intermediate state 72, the output levels of the first and

second hall sensors

142 and 144 are 11.

When the magnet 122 continues to slide rightward and passes right above the first hall sensor 142, the magnet 122 and the interfering magnetic component 160 both have two magnetic line components in the vertical direction of the second hall sensor 122 from bottom to top, the sum of the two magnetic line components is not 0, the output level of the first hall sensor 142 is kept at level 1, that is, the output level of the first hall sensor 142 is not changed.

In the slide-off state 72, the output levels of the first and

second hall sensors

142 and 144 are 10.

That is, when the upper and

lower sliders

second hall sensors

142 and 144 transition in the sequence of 01 → 11 → 10, as in the normal detection process.

It should be noted that the magnetic field of the disturbing magnetic member 160 can be intentionally magnetized by human during the manufacturing process.

Fig. 8 is a flowchart illustrating a method of manufacturing a slide type terminal according to an exemplary embodiment of the present application. The method is used in the manufacturing process of the slide type terminal as shown in fig. 6, and the method comprises the following steps:

step 801, demagnetizing the interference magnetic component;

optionally, the demagnetization process includes both thermal demagnetization and electromagnetic demagnetization processes. Thermal demagnetization: heating a workpiece to be demagnetized to a certain temperature, and then naturally cooling or quenching; electromagnetic demagnetization: a large electromagnetic coil is used to apply AC current to generate a large alternating electromagnetic field, the workpiece to be demagnetized is put in the alternating electromagnetic field, and then the AC current in the coil is gradually reduced to zero.

The demagnetization process is used to demagnetize the magnetic field that interferes with the magnetic device itself.

Step 802, carrying out magnetization treatment on the interference magnetic component to obtain the interference magnetic component after the magnetization treatment;

alternatively, the magnetization treatment includes both thermal magnetization and electromagnetic magnetization processes. Thermal magnetization: heating a workpiece to be demagnetized to a certain temperature, and then naturally cooling or quenching; electromagnetic magnetization: a large electromagnetic coil is used to apply DC current to generate a large alternating electromagnetic field, and the workpiece to be magnetized is placed in the electromagnetic field for a period of time.

The magnetization process is used to generate a magnetic field on the disturbing magnetic component, the direction of which magnetic field and the strength of which magnetic field are controllable.

In the closed state of the sliding cover, the magnet and the interfering magnetic component generate magnetic line components in opposite directions on a vertical plane at the first hall sensor. The vertical plane is a plane perpendicular to the sliding direction.

In one implementation mode, the interference magnetic component installed on the sliding-cover terminal is magnetized, and the magnetized interference magnetic component is obtained. For example, the slider-type terminal mounted with the interfering magnetic component is placed in a magnetic field to be magnetized.

Fig. 8 shows a flowchart of a method for detecting a state of a sliding cover according to an exemplary embodiment of the present application. The method can be applied to the slide type terminal shown in fig. 6. The method comprises the following steps:

step 801, monitoring output levels of a first Hall sensor and a second Hall sensor;

and the output ends of the first Hall sensor and the second Hall sensor are respectively connected with the GPIO port of the processor.

Step 802, when the output levels of the first Hall sensor and the second Hall sensor change according to the sequence of 01, 11 and 10, outputting a sliding cover sliding event when the output level is 10;

with reference to fig. 6 and 7, in the closed state 71, the first hall sensor 142 and the second hall sensor 144 are both located on one side of the direction of the N pole of the magnet 122, the first hall sensor 142 is closer to the magnet 122, a first magnetic line component of the magnet 122 from top to bottom passes through the first hall sensor 142, and a second magnetic line component of the interference magnetic component 160 from bottom to top also passes through the first hall sensor 142, although the first magnetic line component and the second magnetic line component cancel out a part of each other, because the first magnetic line component is greater than the second magnetic line component, that is, the sum of the magnetic line components of the first hall sensor 142 in the vertical direction is from top to bottom, the output level of the first hall sensor 142 is a first level 0, and the first level 0 may be a low level; the second hall sensor 144 is farther from the magnet 122 and the interfering magnetic member 160, and is less affected by the magnet 122, and the output level of the second hall sensor 144 is a second level 1, which may be a high level. That is, in the closed state, the output levels of the first and

second hall sensors

142 and 144 are 01.

In the intermediate state 72, the output levels of the first and

second hall sensors

142 and 144 are 11.

In the slide-off state 72, the output levels of the first and

second hall sensors

142 and 144 are 10.

That is, when the upper and

lower sliders

second hall sensors

142 and 144 are shifted in the sequence of 01 → 11 → 10, the same as the normal detection process

And 803, when the levels output by the first Hall sensor and the second Hall sensor respectively change according to the sequence of 10, 11 and 01, outputting a sliding closure closing event when the output level is 01.

Conversely, when the upper and

lower sliders

second hall sensors

142 and 144 transition in the order of 10 → 11 → 01, and the program code executed by the processor 146 generates and outputs a slider closing event when the output level is 01.
