Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention.

Specifically, as shown in fig. 1 and fig. 2, fig. 1 shows an example where the electronic device is a mobile phone, fig. 1 shows a back surface of the mobile phone, and the electronic device (i.e., the mobile phone) includes a housing 10, a contact interface 20, and a driving mechanism 30, and a main structure of the electronic device will be described below.

The housing 10 defines an inner cavity (not numbered, see the lower portion of the housing 10 in fig. 2) and a through hole 101 communicating with the inner cavity, and the driving mechanism 30 is disposed in the inner cavity. The contact interface 20 includes a plurality of contacts 201, the plurality of contacts 201 are movably disposed in the housing 10, the contacts 201 are connected to the driving mechanism 30, and the contact interface 20 has a first state and a second state.

With the contact interface 20 in the first state: the drive mechanism 30 drives all of the contacts 201 to protrude out of the housing 10 through the perforations 101 to a first height. Referring to fig. 2, the first height may be a distance between the top of the contact 201 of fig. 2 to the upper surface of the housing 10. The first state may also be referred to as a communication interface state, i.e. the contact interface 20 is used to implement the functionality of the communication interface.

With the contact interface 20 in the second state: the driving mechanism 30 drives at least a part of the contact 201 to retract into the housing 10 through the through hole 101; alternatively, the driving mechanism 30 drives at least a portion of the contacts 201 to protrude out of the housing 10 through the through holes 101 to a second height, which is greater than the first height. The second state may also be referred to as a braille display state, i.e., the contact interface 20 is used to implement the braille display function.

The contact interface 20 mentioned above includes a plurality of contacts 201, and fig. 1 schematically shows 24 contacts 201, and the 24 contacts 201 are arranged in an array of three rows and eight columns.

Alternatively, the number of through holes 101 is the same as the number of contacts 201, and the contacts 201 correspond to the through holes 101 one by one, and fig. 2 shows one contact 201 and its corresponding through hole 101.

Optionally, the housing 10 has a plurality of interface regions (i.e. two interface regions shown in fig. 2) distributed at intervals, the interface region includes a plurality of through holes 101 and a plurality of contacts 201, and the plurality of through holes 101 and the plurality of contacts 201 are distributed in an array in the interface region, which can be specifically seen in fig. 3.

As shown in fig. 2, a driving module 30 for driving the plurality of contacts 201 to ascend and descend is disposed at the bottom of the plurality of contacts 201, and the driving module 30 may be a micro step driving motor.

When the driving module 30 is plural, for example, when the plural contacts 201 correspond to the plural driving modules 30 (for example, driving motors), that is, when one driving module 30 is disposed at the bottom of each contact 201, the electronic device may further include a controller (not shown), and the controller and each of the plural driving modules 30 are electrically connected.

In one embodiment, as shown in fig. 2, the driving module 30 is specifically a driving motor 30, and the driving motor 30 includes a motor shaft 301 and a motor body (not numbered), and the surface of the motor shaft 301 is provided with an external thread (not shown). Meanwhile, a connecting part 2011 is arranged at the bottom of the contact 201, the connecting part 2011 is roughly tubular (the length direction is shorter), an internal thread is arranged on the inner surface of the connecting part, and the internal thread is matched with the external thread; the motor shaft 301 of the driving motor 30 is movably connected with the contact 201 through the external thread and the internal thread, and the contact 201 is hollow at the middle-lower part according to the direction shown in fig. 2, and the middle-upper part of the motor shaft 301 can be accommodated in the chamber of the contact 201.

By the above-mentioned connection manner of the driving motor 30 and the contact 201, when the motor shaft 301 of the driving motor 30 rotates in the first direction (for example, rotates forward), the contact 201 can be lifted. For example, the top of the contact 201 rises to a first height or a second height; when the motor shaft 301 of the driving motor 30 rotates in a second direction (e.g., reversely), the contact 201 is driven to descend, for example, the top of the contact 201 retracts into the housing 10.

It should be noted that in the embodiment shown in fig. 2, when the motor shaft 301 rotates to move the contact 201 up or down, the contact 201 is normally kept in a non-rotating state. Specifically, the contact 201 may be provided with a member for restricting its rotation on the surface thereof. Specifically, for example, the contact 201 has a rectangular partial cross section, and the cross section of the through hole 101 in the electronic device case 10 is substantially rectangular, and the rotation of the contact 201 is restricted by the shape of the through hole 101.

It should also be noted that the distance that the plurality of contacts 201 are raised or lowered is generally predetermined and can be achieved by controlling the number of rotations of the motor shaft 301. Specifically, in the orientation shown in fig. 2, the tops of the plurality of contacts 201 are either in a first position at a first level, i.e., the tops of the plurality of contacts 201 are at a first height; either the tops of the plurality of contacts 201 are in the second position at the second level, i.e., the tops of the plurality of contacts 201 are at a second height, which is greater than the first height, or the tops of the plurality of contacts 201 are retracted within the housing 10 and the tops of the plurality of contacts 201 are flush with the outer surface of the housing.

It is mentioned in the foregoing that the electronic device may further include a controller, which may be configured to generate first driving information based on the obtained braille information, and control the driving module 30 based on the first driving information; thus, the driving module 30 can drive the plurality of contacts 201, for example, drive part or all of the contacts 201 to rise; the position of some or all of the contacts 201 is not changed (i.e., not raised or lowered); drive some or all of the contacts 201 down, and so on.

The above description mainly describes the principle of implementing the braille display of the contact interface 20, and the braille display thereof will be briefly described below. The braille display is also called a braille display, and the international braille generally consists of individual character units each of which is generally composed of 6 contacts.

The electronic device provided by the embodiment of the invention can display 4 braille characters through the contact interface 20, specifically as shown in fig. 3, a black circle in fig. 3 represents a salient point, that is, the contact 201 rises to the highest position; the open circles indicate no bump, i.e., the contact 201 is lowered to the lowest position.

Specifically, the highest position may be that the top of the contact 201 is at the second height, and correspondingly, the lowest position is that the top of the contact 201 is at the first height; alternatively, the highest position may be that the top of the contact 201 is at a first height, and correspondingly, the lowest position is that the top of the contact 201 is retracted into the housing 10.

In fig. 3, the left 12 contacts 201 may display two characters, and the right 12 contacts 201 may display two characters.

Meanwhile, the electronic device provided by the embodiment of the present invention further includes a plurality of limiting members (not shown), where the limiting members are configured to be in limiting fit with the contacts 201 when the contacts 201 extend out of the housing 10 (to the first height or the second height) and/or retract into the housing 10, that is, the contacts 201 are controlled not to move up and down. Alternatively, the plurality of limit members may be the driving motor 30 in particular.

Optionally, the electronic device further comprises a locking module 202, or braille function switch point. When the locking module 202 is turned on (i.e., the function expansion module is externally connected), under the restriction of the plurality of limit pieces, the tops of all the contacts 201 are located in the same horizontal plane, and the positions of all the contacts 201 are locked (i.e., cannot rise or fall), so that the contact interface 20 is used as a communication interface; when the locking module 202 is not turned on, referring to the state shown in fig. 3, all the contacts 201 may be raised or lowered under the control of the controller and driving module 30, and the contact interface 20 serves as a braille display interface.

In the embodiment of the invention, the controller relates to a high-speed digital processor and a built-in control algorithm, and when the Braille content needs to be displayed, the high-speed digital processor controls the driving motor 30 to realize the display of the Braille content. When the communication interface is needed, the high-speed digital processor controls the driving motor 30 to lock the position of each contact 201, thereby realizing stable data communication.

Optionally, for user convenience, the driving motor 30 is usually accompanied by corresponding sound effects and vibration feedback to give the user accurate tactile feedback. That is, when characters are displayed in a braille display device in a changing manner, a changing sound and vibration feedback can be given.

Specifically, in one embodiment, the braille display device shown in fig. 1 further includes an audio output module that outputs audio when the driving module 30 drives the plurality of contacts 201 to ascend and descend.

Specifically, in one embodiment, the braille display device shown in fig. 1 further includes a vibration module, which gives a vibration prompt when the driving module 30 drives the plurality of contacts 201 to ascend and descend.

Alternatively, the controller and the plurality of driving motors 30 in the braille display device shown in fig. 1 are electrically connected by a plurality of signal lines arranged in rows and columns; the plurality of driving motors 30 are located at the intersections of the plurality of signal lines, and the plurality of contacts 201 are located at the intersections of the plurality of signal lines.

Referring to fig. 4 specifically, in fig. 4, the control manner of the array-type driving motors 30 is similar to the control manner of the screen LED, and both the control manner is controlled by the row selection signal and the column selection signal, where the row selection signal and the column selection signal are numbered, which is equivalent to that each driving motor 30 is uniquely numbered. Each driving motor 30 is located at the intersection of the row and column signals, accordingly, the plurality of contacts 201 are located at the intersection of the plurality of signal lines, see the black dot position shown in fig. 4, and the control signal controls each driving motor 30 through the row selection signal and the column selection signal to drive the contacts 201 to ascend and descend.

And after the fact that the time length from the contact to the second height extending out of the shell exceeds a first preset time length is detected, controlling the driving mechanism to drive the contact to extend out of the shell to the first height.

The embodiment can automatically recover the data transmission function of the contact interface after the time length for not displaying the braille information exceeds the first preset time length, does not need to be automatically controlled by a user, better accords with the use habit of the user, and improves the user experience.

Optionally, after controlling the driving mechanism to drive a plurality of the contacts according to the first driving information, the method further includes: and under the condition that a second preset time length is reached, controlling the driving mechanism to drive the plurality of contacts again according to the first driving information.

In the embodiment, the number of the braille characters which can be displayed at one time by the contact interface 20 (for example, 4 braille characters in fig. 3) is far larger than the number of the braille characters which can be displayed at one time by the obtained braille information, so that after every 4 braille characters are displayed, the back 4 braille characters can be displayed at intervals of the second preset time length, and the braille characters can be conveniently viewed by a user until all the braille characters are displayed.
