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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The core of the utility model is to provide a touch screen display device of an ultrasonic device, which can control the opening and closing of a touch screen through the position of the touch screen, so as to avoid the abnormal touch state caused by the cover opening and closing operation.

Another core of the present invention is to provide an ultrasound apparatus including the touch screen display device described above.

Referring to fig. 1 to 6, the present invention provides a touch screen display device of an ultrasound apparatus, including a main body 1 and a movable portion 2 openable and closable relative to the main body 1, where the main body 1 and the movable portion 2 may be connected in a sliding manner or hinged. The touch screen display device further includes a touch screen 3, a distance detection device, and a controller.

The touch screen 3 is arranged on the movable part 2, and when the movable part 2 faces the main body 1 and approaches, the touch screen 3 arranged on the movable part faces the main body 1 and approaches. It can be understood that when the main body 1 and the movable part 2 are connected in a sliding manner, the movable part 2 is close to the main body 1, so that the movable part 2 gradually slides towards the main body 1 until covering the main body 1; when main part 1 and movable part 2 are articulated, movable part 2 is close to main part 1 and for the contained angle between movable part 2 and the main part 1 dwindles gradually until the contained angle is zero.

The distance detection device is used for realizing fixed-point distance measurement, and particularly, one of the distance detection device and the reference point is arranged on the main body, the other one of the distance detection device and the reference point is arranged on the movable part, and the distance detection device is used for detecting the distance relative to the reference point and sending a trigger signal to the controller when the distance meets the condition. When the detected distance meets the condition, the distance detection device generates a trigger signal based on the physical property of the distance detection device, and then sends the trigger signal to the controller. Further, the distance detection means may transmit the trigger signal to the controller based on a cable line with the controller after generating the trigger signal.

One of the distance detection means and the reference point is located at the main body 1, and the other is located at the movable portion 2. It is understood that the distance between the distance detecting means and the reference point can be simply understood as the distance between the main body 1 with respect to the movable part 2. In addition, the touch screen 3 is provided to the movable portion 2, and thus the distance between the distance detection means and the reference point can be simply understood as the distance between the main body 1 with respect to the touch screen 3.

The controller is connected with the touch screen 3 and the distance detection device, and the controller is used for controlling the touch screen 3 to be closed or opened when receiving the trigger signal.

In the operation process, when the touch screen 3 is close to the main body 1 and reaches a preset position, the distance detection device determines that the distance between the touch screen 3 and the reference point meets a closing condition, and the controller controls the touch screen 3 to be closed; when the touch screen 3 is far away from the main body 1 and reaches a preset position, the distance detection device determines that the distance between the touch screen 3 and the reference point meets the starting condition, and the controller controls the touch screen 3 to be started. The turning off of the touch screen 3 refers to cutting off the power supply of the touch screen 3 or controlling the locking of the touch screen 3, that is, the output or the reception of the touch signal is not performed any more; correspondingly, the turning on of the touch screen 3 means that the power of the touch screen 3 is turned on, or the unlocking of the touch screen 3 is controlled, that is, the output or the reception of the touch signal is started.

Specifically, the distance condition is a distance threshold between the distance detection device and a reference point during the opening operation and the closing operation, the distance threshold is preferably a distance between the distance detection device and the reference point when the distance detection device is close to the full opening, and the controller controls the touch screen to change the working state when the position relationship reaches a preset position, wherein the working state comprises opening or closing. In an alternative embodiment, the distance detection means generates a trigger signal and sends the trigger signal to the controller when determining that the distance to the reference point is less than the distance threshold, and the controller controls the touch screen 3 to close when receiving the trigger signal.

It should be noted that the reference point may be a point at a preset position. Reference point in this application can be same position, or can not be restricted to same position, takes movable part 2 to articulate in main part 1 as an example, when rotatory in order to close movable part 2, can be when the contained angle theta of movable part 2 and main part 1 is 60 degrees, and control closes touch-sensitive screen 3 to when rotatory in order to open movable part 2 to two contained angles theta is 50 degrees, control opens touch-sensitive screen 3. That is, the positions corresponding to the opening and closing may be different.

The distance detection device detects the distance relation of the touch screen 3 relative to the main body 1, the controller controls the opening and closing of the touch screen 3 through the current distance relation and the preset distance, when the lock moving part 2 is far away from the preset distance, the touch screen 3 is controlled to be closed, the touch screen is always in a working state when the moving part 2 is prevented from being adjusted, and the conditions of communication abnormity and control abnormity are avoided. That is to say, the operation of opening or closing the movable portion 2 can correspondingly realize the opening or closing of the touch screen 3, so that the opening and closing of the touch screen 3 no longer depends on the operation selection of the user on the system, and the abnormal touch state caused by the operation of opening and closing the cover is avoided.

On the basis of the above embodiment, the movable portion 2 is hinged to the main body 1.

In a specific scheme, when the movable part 2 is hinged to the main body 1, the movable part 2 and the main body 1 are relatively unfolded to be in an opening state of the movable part 2; the movable portion 2 is folded relative to the main body 1, and the movable portion 2 is in a closed state.

The condition that the distance needs to satisfy may be converted into an angle condition, that is, it may be ensured that the distance between the movable part 2 and the main body 1 also satisfies the distance condition when the angle between the movable part 2 and the main body 1 satisfies a specific condition. The range corresponding to the angle condition is a position where the angle θ between the touch screen 3 and the main body 1 is greater than or equal to 70 degrees. Taking the condition of the included angle as an example that the included angle theta between the touch screen 3 and the main body 1 is 70 degrees, that is, when the touch screen 3 approaches the main body 1 and the included angle theta between the touch screen 3 and the main body is less than or equal to 70 degrees, the controller controls the touch screen 3 to be closed; and when the touch screen 3 is far away from the main body 1 and the included angle theta between the touch screen 3 and the main body 1 is larger than 70 degrees, the controller controls the touch screen 3 to be started.

Alternatively, the movable portion 2 is slidably provided in the main body 1. When the two slide to the completely overlapped position, the movable part 2 is in a closed state; the movable section 2 is folded relative to the main body 1, and the movable section 2 is in an open state.

The condition that the distance needs to be satisfied may be converted into an area ratio condition, that is, it is possible to ensure that the distance between the movable part 2 and the main body 1 also satisfies the distance condition when the area ratio satisfies a specific condition. The range corresponding to the area ratio condition is a ratio of an overlapping area of the touch panel 3 and the main body 1. Taking the area ratio condition as 70% of the overlapping area of the touch screen 3 and the main body 1 as an example, namely when the touch screen 3 slides opposite to the main body 1 until the overlapping area ratio is increased to 70%, the controller controls the touch screen 3 to be closed; and when the touch screen 3 slides away from the main body 1 until the overlapping area ratio is reduced to 70%, the controller controls the touch screen 3 to be opened.

The main part 1 of this application and activity portion 2 specifically are the equipment of the switching of can overturning, and under the two lock state, be close to each other and parallel, perhaps the two laminating sets up, and the distance detection device that the two set up can include the detection type of multiple difference, for example through modes such as infrared range finding, ultrasonic ranging, magnetic induction range finding. Therefore, in the present application, the physical property of the detection device determines whether the two parts respectively realize sending and receiving of the sensing signal, and if the laser ranging is performed, the two devices are required to respectively send and receive the detection signal, so as to realize ranging; if the distance measurement is magnetic induction, two devices are needed, one device sends out a magnetic signal and the other device receives the magnetic signal, so that the distance measurement is realized; however, if ultrasonic distance measurement is adopted, only the ultrasonic generator needs to send ultrasonic waves and wait for receiving.

On the basis of the above embodiment, the distance detection means includes the magnet 5 and the hall sensor 6 for sensing the magnet 5, one of which is provided in the movable portion 2 and the other of which is provided in the main body 1, and the movable portion 2 and the main body 1 are connected by the hinge shaft 7. The hall sensor 6 is connected to the controller, and when the magnetic signal that the hall sensor 6 detected satisfied the condition, it was judged that the distance between the movable part 2 and the main part 1 satisfied the condition, and its output port was to the low level of controller output, and when the magnetic signal that the hall sensor 6 detected did not satisfy the condition, it was judged that the distance between the movable part 2 and the main part 1 did not satisfy the condition, and its output port was to the high level of controller output. Wherein, the magnetic signal satisfying condition may be that the magnetic induction is greater than the magnetic induction threshold.

The controller determines the distance between the main body 1 and the movable part 2 in the current state through the obtained high-low level signal, thereby controlling the on or off of the touch screen. Further, the controller controls the touch screen to be turned on when receiving the high level output by the hall sensor 6, and controls the touch screen to be turned off when receiving the low level output by the hall sensor 6.

When movable part 2 closed in main part 1, magnet 5 just is to setting up with hall sensor 6, specifically, magnet 5 sets up in main part 1, and hall sensor 6 sets up in movable part 2, and magnet 5 equals with hall sensor 6 to articulated shaft 7's distance, and magnet 5 is perpendicular all the time with hall sensor 6's line and articulated shaft 7.

The entirety of the magnet 5 and the hall sensor 6 may be a distance detection means. When the movable part 2 rotates relative to the main body 1, the distance of the magnet 5 relative to the hall sensor 6 changes, that is, the position of the magnet in the magnetic field changes, and thus the hall sensor 6 detects a change in data. When the detected data change reaches the set condition, the Hall sensor 6 outputs a trigger signal to the controller. In addition, the controller can obtain the relative position change of the touch screen 3 and the main body 1 through the relative position change of the magnet 5 and the hall sensor 6.

Alternatively, the magnet 5 may be provided with one or more magnets, the positions of which may have different distances with respect to the hall sensor 6, in order to be detected separately during rotation.

The accuracy of detection effect can be guaranteed by adopting the Hall sensor, and compared with the mode of adopting laser and the like, more external interference can be avoided, and the accuracy of detection result is avoided being interfered by the outside.

In a specific embodiment, the magnet 5 and the hall sensor 6 are both disposed away from the hinge shaft 7.

It should be noted that the sensor is disposed at a position far away from the hinge shaft 7, that is, at a side where the main body 1 and the movable portion 2 are turned to open and close, and this side can sense the change of the distance between the two in the just opened state, so that the sensor is suitable for sensing the opening of the movable portion 2.

In a specific embodiment, the magnet 5 and the hall sensor 6 are provided near the hinge shaft.

Is arranged at a position close to the hinge shaft 7, can sense the distance change of the movable part 2 in a sensitive manner when the movable part is in a closed state, and is suitable for sensing the closing of the movable part 2.

Alternatively, the number of the distance detection devices may be 1, or 2 or more. When the number of the sensors is 2 or more than 2, at least two distance detection devices may be provided at different positions of the main body 1 and the movable portion 2 to sense relative positional relationships in different states, respectively.

Therefore, the number of distance detection means provided in the above configuration can be adjusted according to the actual size of the movable portion 2 and the use requirement.

On the basis of the above embodiment, the number of the magnets 5 is at least two, and the hall sensors 6 are arranged in one-to-one correspondence with the magnets 5, and are sequentially arranged in the direction perpendicular to the hinge shaft 7.

When at least two distance detection devices are provided, if the distance detection devices are provided at different positions, the sensing time may be different and the effect may be different in the process of rotating the movable portion 2. The hall sensors 6 corresponding to different magnets 5 can be made to detect the same magnetic induction at the same time by controlling the difference in size of the magnets 5, or different preset values can be set in the controller.

For example, three magnets 5 are provided in total, including a first magnet 51, a second magnet 52 and a third magnet 53, arranged in sequence in a direction perpendicular to the hinge axis 7, the first magnet 51 being close to the hinge axis 7, the third magnet 53 being far from the hinge axis 7, the second magnet 52 being located in the middle; and three hall sensors are arranged, the three hall sensors comprise a first hall sensor 61, a second hall sensor 62 and a third hall sensor 63, the three hall sensors are sequentially arranged along the direction perpendicular to the hinging shaft 7, the first hall sensor 61 is close to the hinging shaft 7, the second hall sensor 62 is positioned in the middle, and the third hall sensor 63 is far away from the hinging shaft 7.

Referring to fig. 5 and 6, if the first hall sensor 61 is too close to the hinge shaft 7, the situation of the first position in fig. 6 occurs, that is, in the state of being opened to 180 degrees, at the position of the first position in fig. 6, which is a position corresponding to 4, the magnetic flux density is still above the level of the magnetic field release line Brp, that is, the magnetic flux density is still a value that can be sensed, and the hall sensor can still sense the magnetic flux, and may send a high-level signal, which may cause inaccurate sensing.

If the specification of three magnet 5 is the same basically, then the magnetic field of production is the same basically, if need three hall sensor 6 to sense magnet 5 simultaneously on corresponding position, then can be through setting up the inductive value of three difference, when movable part 2 rotates to contained angle theta with main part 1 and is 60 promptly, the detected value of the corresponding magnet 5 that three hall sensor 6 sensed, numerical value that corresponds for predetermineeing the position promptly, it is very obvious that the detected value that three hall sensor 6 sensed is different in this position department, also be exactly through setting for the different numerical values that predetermine the position and correspond, make three hall sensor 6 can respond to simultaneously.

In another embodiment, three hall sensors 6 are not required to sense and trigger the control operation of the controller at the same time, the three hall sensors may have differences, and the controller may control the touch screen to be turned off or on when any one of the hall sensors 6 detects that the touch screen 3 reaches the preset position. That is, a plurality of sensing mechanisms can be formed by the cooperation of two or more hall sensors 6 and the magnet 5, and the control is performed by the hall sensor 6 which is detected first, so that the most sensitive control of the touch screen 3 is formed.

On the basis of the above-described embodiment, the magnets 5 are uniformly arranged on the main body 1 in the direction perpendicular to the hinge shaft 7. The purpose of even setting lies in conveniently realizing the setting to the position of predetermineeing that prestores in the controller to it is more accurate to guarantee that the detected value corresponds rather than.

Besides even arrangement, the distance can be arranged in an increasing or decreasing mode, and the specific difference value can be arranged in a stepped mode.

On the basis of the above-described respective embodiments, all the magnets 5 are arranged in parallel, and the magnetic pole directions of all the magnets 5 are the same. By this arrangement, the response directions of the hall sensors arranged corresponding to the respective magnets are made the same, for example: when the movable part 2 is closed on the main body 1, the magnetic induction intensity detected by each hall sensor is constantly enhanced. Therefore, the touch screen 3 can be triggered to be turned off or the touch screen 3 can be triggered to be turned on, rather than some hall sensors triggering the touch screen 3 to be turned off and some hall sensors triggering the touch screen 3 to be turned on.

The parallel arrangement means that after all the magnets 5 are installed, the extending directions of the N pole and the S pole are the same, the magnetic pole directions of the magnets 5 are the same, that is, the N poles of all the magnets 5 face one direction, and correspondingly, the S poles face one direction.

If the magnets 5 are disposed on the movable portion 2, the connecting line of the N pole and the S pole of all the magnets 5 is perpendicular to the plane of the movable portion 2 for mounting the touch screen 3.

On the basis of any of the above embodiments, the line connecting the poles of the magnet 5 is perpendicular to the plane of the main body 1 facing the touch screen 3. The plane of the body 1 facing the touch screen 3 is often the principal plane (i.e. the plane with the largest area fraction) on the body 1 or a plane parallel to the principal plane. Thus, in other words, the magnet 5 is arranged perpendicularly with respect to the main plane of the body 1.

In the above embodiment, the magnet 5 and the hall sensor 6 are disposed opposite to each other in the closed state of the movable portion 2, and specifically, in the present embodiment, when the movable portion 2 is closed to the main body 1, the straight line where the connecting line of the two poles of the magnet 5 is located passes through the corresponding hall sensor 6. That is, when the movable portion 2 is closed to the main body 1, the magnet 5 and the hall sensor 6 are in a state of being closest to each other and having a maximum magnetic flux, so that the most significant effect of the change in the detection value of the hall sensor 6 during the detection process can be ensured.

As can be seen from the use of the hall sensor 6, it is necessary to use a way in which one pole faces the hall sensor 6 and the other pole faces away from the hall sensor 6. Close to the hall sensor 6, but not both poles, so that it is correct that the magnet 6 needs to be in a straight line close to the hall element in the closed state, and it is not possible to place the magnet at an angle.

In the present application, the hall sensor 6 may output different levels through an output terminal to implement the transmission of the controller signal, and reference may be made to the related art.

In a specific embodiment, the hall sensor 6 and the magnet 5 are centrally positioned in an aligned state in the closed state of the movable portion 2.

In a specific embodiment, when the hall sensor 6 is sufficiently close to the magnet 5, a distance h of 2mm to 8mm is required to be kept between the hall sensor 6 and the magnet 5, so as to avoid inaccurate detection caused by too close distance.

On the basis of any one of the above embodiments, the magnet 5 is a neodymium iron boron magnet, which has strong magnetic force, high cost performance, wide application range and good mechanical properties.

Alternatively, in order to fit the structural dimensions of the ultrasound device, in a specific embodiment, the neodymium iron boron magnet (NdFeB) may have dimensions of 5.5 × 4.5 × 2.5mm and the magnetic flux is specifically 3000 gauss.

The neodymium iron boron magnet has the characteristics of small volume, light weight, strong magnetism and the like, but in the conventional use, electroplating is basically carried out, otherwise, rustiness is easy to happen, and the result that the neodymium iron boron magnet cannot be used is caused.

Thus, in a specific embodiment, the exterior of the magnet 5 is provided with a protective coating to prevent oxidation, knocks, etc. Optionally, the protective film outside the magnet 5 is a zinc coating.

Optionally, the protective film may be another type of coating film.

In addition to any of the above embodiments, the controller is further connected to the main display 8 of the main body 1 for controlling the main display 8 to open and close synchronously with the touch screen 3.

In the above embodiments, the opening and closing of the electrical performance of the touch screen 3 is controlled by detecting the opening and closing of the movable portion 2, so that the touch screen 3 can be prevented from being abnormally touched, and on the basis, the touch screen display device can further be provided with the main display 8, in a normal case, the touch screen 3 is used for realizing operation, and an operation result of the ultrasonic device is displayed on the main display 8, so that the main display 8 needs to be closed when the touch screen 3 is closed. The main display 8 may be switched between open and closed states by opening and closing the movable portion 2.

On the basis of any of the above embodiments, the controller is further connected to the control system of the ultrasound apparatus, and is used for controlling the control system to go to sleep or wake up.

It should be noted that the above-mentioned sleep or wake-up refers to control over the system, or control over the signal transmission state between the system and the touch screen 3 and the main display 8, and correspondingly, the sleep refers to that the system does not send information to the touch screen 3 and the main display 8 any more, and the wake-up refers to a transmission path through which the system communicates with the touch screen 3 and the main display 8 to send information to the touch screen 3 and the main display 8.

On the basis of any of the above embodiments, the controller counts a preset time after receiving that the movable portion 2 rotates or moves to the fully opened state, and then starts signal transmission between the controller and the touch screen 3. The preset time may be a very short time, for example, 1 second.

The scheme that this application provided, realize detecting in the switch operation of movable part 2, and can show 3 and 8 module two parts of main display screen to the touch screen and control, when opening and shutting the movable part to not cutting off the power supply, can accomplish to show 3 and main display screen 8 through the touch screen of distance monitoring switch, during the state that detects to close lid or uncap, signal or data that send touch-control screen 3 do not all deal with, opening movable part 2 back, about 1 second is left and right, begin to receive touch-control screen 3's signal.

The scheme provided by the application can meet the actual use requirements of a doctor when in use, avoids electric energy waste, avoids instability of touch control, improves medical use experience, meets the convenience of the doctor, and reduces the problem that the switch cover is abnormal in touch control in the operation of a system; and the resources can be fully utilized, the effect is improved, and the comprehensive cost of the medical product is reduced.
