Description
Technical Field
The disclosure relates to the field of electromechanical technology, in particular to a control panel and a control method thereof, and also relates to electronic equipment comprising the control panel.
Background
Currently, most electronic devices include a manipulation panel for operating the same. Generally, the operation based on the dashboard includes two common modes of operation, namely: touch operations based on the touch panel, such as clicking, sliding, and the like; and key operations based on physical keys. The touch panel and the physical key have advantages and disadvantages, and are used in different application scenes. For example, the touch panel is dustproof and waterproof, the sliding touch is easy to realize directional control, the sliding touch is easy to define various gesture operations, so that various kinds of commands can be realized, but the clicking area of an adjacent area on the touch panel is not high in scale, and the touch feedback is poor, so that the touch panel is generally applicable to directional control such as left, right, up and down movement and gesture operations such as circle, W, Z and the like; the clicking touch of the entity key is strong, the clicking distinction degree of different keys is high, but the dust prevention and water prevention design of the entity key is difficult, and the occupied space is large, so the entity key is generally suitable for typing input such as a nine-grid keyboard, and special function operations such as volume addition and subtraction, startup and shutdown and the like.
Some electronic devices may include two types of control panels based on actual needs. For example, virtual Reality (VR) handles currently in the market include both touch panels and mechanical physical keys that are spatially separated from each other. However, this design is only suitable for application scenarios with a small number of keys, and for application scenarios with a relatively large number of keys, the separately designed physical keys will occupy too much space, resulting in a VR handle that is bulky and heavy and inconvenient for one-handed operation.

Detailed Description
The following description provides detailed descriptions of specific details of various exemplary embodiments of the disclosure in order to enable those skilled in the art to fully understand and practice the various exemplary embodiments of the disclosure.
First, some terms involved in exemplary embodiments of the present disclosure are explained to facilitate understanding of the present disclosure by those skilled in the art. These terms should be understood in light of the following explanation, unless stated to the contrary, in this disclosure.
Cylindrical projection expansion diagram: the object is projected onto the cylindrical surface along a radial direction perpendicular to and intersecting the longitudinal center axis of the cylindrical surface, and then the cylindrical surface is unfolded into a plane.
Radial projection: a projection view obtained by projecting the object onto the cylindrical surface along a radial direction perpendicular to and intersecting the longitudinal center axis of the cylindrical surface.
Further, unless stated to the contrary, the longitudinal direction of a component having a lengthwise shape is referred to herein as the direction along the lengthwise axis of the component, and the radial direction is referred to as the direction perpendicular to and intersecting the lengthwise axis.
Referring to fig. 1, a general application scenario of a manipulation panel according to an exemplary embodiment of the present disclosure is schematically illustrated. As shown in fig. 1, the manipulation panel 100 includes a first manipulation surface 110 and a second manipulation surface 120. Fig. 1 (a) schematically shows a touch application scenario of the manipulation panel 100. At this time, the second operation surface 120 is at the first position such that the first operation surface 110 and the second operation surface 120 are kept flush, thereby collectively forming a touch operation surface of the manipulation panel 100 for performing various touch operations. For example, but not limited to, directional control such as left, right, up, down movement, and gesture operations such as circle, W, Z, etc. Fig. 1 (b) schematically shows a key application scenario of the dashboard 100. At this time, the second operation surface 120 is in the second position such that the first operation surface 110 protrudes with respect to the second operation surface 120, whereby the first operation surface 110 forms a key for key operation.
It should be understood that fig. 1 only shows a case where the first operation surface 110 forms a nine-grid key array arranged in a 3×3 form in a key application scene, but the first operation surface 110 may form any form of keys according to actual needs, including, but not limited to, individual keys for realizing specific operations (volume addition and subtraction, power on and off, etc.), or a plurality of keys arranged in any suitable form, for example, including a key array having more or fewer rows and columns. The present disclosure is not limited in this regard.
Referring to fig. 2, an application scenario in which a manipulation panel is applied to a VR handle for text input according to an exemplary embodiment of the present disclosure is schematically illustrated. At this time, the manipulation panel on the VR handle may be in a key application scene and formed as a nine-grid key array arranged in a 3×3 form. When the characters are input, the actual positions of the thumbs of the user for inputting the characters can be displayed on the VR display interface in real time through the camera on the VR device. As shown in fig. 2, the positions of the thumbs corresponding to the left and right handles, respectively, can be captured by the camera. In this way, the user can perform the text input operation through the VR handle as the text input operation is performed on the mobile phone, so that the text input speed is greatly improved. From this, can solve the slow problem of present VR handle text input through being applied to the VR handle with the control panel according to this disclosure.
It should be understood that the manipulation panel according to the present disclosure can be applied to various suitable electronic devices. Such electronic devices include, but are not limited to: gaming machines, smart televisions, smart speakers, projectors, set-top boxes, smart phones, personal Digital Assistants (PDAs), notebook computers, tablet computers, various virtual reality and/or augmented reality devices, and the like, as well as wearable computing devices such as smart watches and bracelets, smart glasses, and the like. The present disclosure is not limited in this regard.
Referring to fig. 3A and 3B, the structure of a manipulation panel according to one exemplary embodiment of the present disclosure is schematically illustrated. As shown in fig. 3A and 3B, the manipulation panel 300 includes a first panel assembly 310, a second panel assembly 320, and a positioning and retaining device 330. The first panel assembly 310 includes a first touch panel 311, a first touch circuit board 312, and keys 313, which are arranged in an overlapping manner, and the first touch circuit board 312 is located between the first touch panel 311 and the keys 313. The first touch panel 311 has a first operation surface 110. The first touch circuit board 312 is used for supporting the first touch panel 311, detecting a touch operation on the first operation surface 110 and generating a corresponding control signal when the first operation surface 110 is used for a touch application, and generating a corresponding key signal in response to a pressing of the key 313 by a user's key operation when the first operation surface 110 is used for a key application. The second panel assembly 320 includes a second touch panel 321 and a second touch circuit board 322, which are overlapped, and the second touch panel 321 has the second operation surface 120. The second touch circuit board 322 is used for supporting the second touch panel 321, and detecting a touch operation on the second operation surface 120 and generating a corresponding control signal when the second operation surface 120 is used for a touch application. The second touch circuit board 322 may include a stopper 3221. As shown in fig. 3A and 3B, the stopper 3221 is a stepped structure formed at a position of the second touch circuit board 322 adjacent to the first touch circuit board 312. When the second operation surface 120 is held at the first position, the stopper 3221 abuts against the first touch circuit board 312, thereby ensuring that the second operation surface 120 is kept flush with the first operation surface 110 while preventing the key 313 from being accidentally pressed. The positioning and retaining device 330 may position and retain the second panel assembly 320 to position and retain the second operative surface of the second panel assembly 320 in the first position or the second position. It should be appreciated that the positioning and retaining device 330 may be any suitable mechanical or electromechanical device, as will be described in detail below. In addition, the manipulation panel 300 may further include a state detection key 340 configured to generate a key operation state signal for instructing the manipulation panel 300 to switch from the touch application scene to the key application scene when the second operation surface 120 is held in the second position.
It should be understood that the first touch panel 311 and the second touch panel 321 may be any suitable type of touch panel as long as it can sense a touch operation of a user; the first touch circuit board 312 and the second touch circuit board 322 may be any suitable form of circuit board including, but not limited to, printed circuit boards, as long as they are capable of performing the above-described functions; the keys 313 and the state detection keys 340 may be any type of keys including, but not limited to, contact keys or non-contact keys, as long as they are capable of performing the above-described functions. The present disclosure is not limited in this regard.
In the exemplary embodiment shown in fig. 3A and 3B, the first panel assembly 310 includes keys 313, however, in other exemplary embodiments, the first panel assembly 310 may not include keys 313. In an exemplary embodiment that does not include the key 313, the first touch panel 311 may sense a key operation of a user while in a key application scene and generate a corresponding key signal through the first touch circuit board 312. In the exemplary embodiment shown in fig. 3A and 3B, the second touch circuit board 322 includes the stopper 3221, but in other exemplary embodiments, the second touch circuit board 322 may not include the stopper 3221. In exemplary embodiments where the second touch circuit board 322 does not include the stop 3221, the second panel assembly 320 may ensure that the second operating surface 120 is held in the first position by any other suitable means, for example, a suitable stop may be provided elsewhere, or the retaining device 330 may be positioned to ensure that the second operating surface 120 is held in the first position and to prevent accidental depression of the keys 313, as will be described below. Furthermore, in the exemplary embodiment shown in fig. 3A and 3B, the dashboard 300 includes the status-detection key 340, but in other exemplary embodiments, the dashboard 300 may also not include the status-detection key 340. In an exemplary embodiment in which the dashboard 300 does not include the status detection key 340, the dashboard 300 may detect the status of the dashboard 300 in any other suitable manner. As a non-limiting example, the manipulation panel 300 may determine the state of the manipulation panel 300 by providing corresponding conductive contacts on the stopper 3221 and the first touch circuit board 312, respectively, and by determining the conduction condition of the conductive contacts.
With continued reference to fig. 3A, the operation panel 300 is shown in a touch application scenario, where the first operation surface 110 and the second operation surface 120 are kept flush to form together a touch operation surface for performing a touch operation on the operation panel 300; fig. 3B shows the case where the manipulation panel 300 is in a key application scenario, where the first operation surface 110 protrudes with respect to the second operation surface 120 to form keys for key operation. Further, in the case shown in fig. 3B, the state detection key 340 is pressed by the second panel assembly 320 to generate a key operation state signal for indicating that the manipulation panel 300 has been switched from the touch application scene to the key application scene.
Referring to fig. 4, a principle of the manipulation panel 300 shown in fig. 3A and 3B to implement a touch operation and a key operation is schematically illustrated. As shown in fig. 4, the touch circuit board 322 and the key touch circuit board 312 are respectively provided with crisscrossed capacitive sensing pads P, which are respectively connected with the transmission channels (i.e., the transmission channels TX1_1 to TX 1_7) and the reception channels (i.e., the reception channels RX1_1 to RX 1_7) of the chip 400. It should be noted that a column of the capacitive sense pads P connected to one transmit channel is not conductive to the other capacitive sense pads P, and similarly, a row of the capacitive sense pads P connected to one receive channel is also not conductive to the other capacitive sense pads P. When a finger touches directly above the corresponding capacitive sensing pad P, the mutual inductance capacitance value between the capacitive sensing pad P connected to the transmitting channel and the capacitive sensing pad P connected to the receiving channel may change. Therefore, when the current value sent by the sending channel is fixed, the voltage rising time corresponding to the receiving channel is changed, so that it can be judged that the intersection area of the capacitance sensing pad P of the sending channel and the capacitance sensing pad P of the receiving channel has finger contact. When the control panel 300 is in the touch application scenario, the chip 400 can detect the mutual inductance capacitance value between the corresponding capacitance sensing pads P, so as to detect the touch operation on the control panel 300.
Signals of the key 313 and the state detection key 340 are both accessed to the chip 400. These keys may have two different states, e.g., released and pressed, which may correspond to different voltage values, respectively, whereby the chip 400 is able to determine whether the corresponding key is pressed. The keys 313 may be used for text, control command input. The status detection key 340 may be used to detect whether the second panel assembly 320 is pressed, so that different application scenarios may be determined. As a non-limiting example, when the state detection key 340 is pressed, it indicates that the dashboard 300 is in a key application scenario, and when the state detection key 340 is released, it indicates that the dashboard 300 is in a touch application scenario. In a key application scenario, the system software may ignore touch actions on the first operation surface 110, only in response to key operations. The second operation surface 120 may still respond to the touch operation according to actual needs, but may not respond to the touch operation. In the touch application scenario, the first operation surface 110 and the second operation surface 120 together form a touch operation surface of the control panel 300, and the key 313 cannot be pressed at this time, so that the control panel 300 can only respond to the touch operation.
Referring to fig. 5, a structure of a locking mechanism that can be used for the positioning and holding device 330 of the manipulation panel 300 shown in fig. 3A and 3B is schematically shown. As shown in fig. 5, locking mechanism 600 includes cam sleeve 610, push rod sleeve 620, cam lever 630, and spring 640, which are assembled together as shown to form locking mechanism 600. The cam sleeve 610 has a hollow cylindrical shape with one end closed and the opposite end open so as to accommodate the push rod sleeve 620, the cam rod 630 and the spring 640.
Fig. 6 schematically illustrates cam sleeve 610 in an end view of the open end of cam sleeve 610, and fig. 9 schematically illustrates a cylindrical projection deployment view of various components in locking mechanism 600 illustrated in fig. 5. Referring to fig. 6 and in combination with fig. 5 and 9, the cam sleeve 610 is provided at an inner wall thereof with four grooves 611 uniformly distributed in a circumferential direction. Accordingly, the cam sleeve 610 forms a cam portion 612 between each two of the four grooves 611 in the circumferential direction. Thus, the four grooves 611 and the four cam portions 612 are uniformly and alternately arranged in the circumferential direction. As a non-limiting example, as shown in fig. 9, the radial projections of the four cam portions 612 may be in the ranges of 0 to 67.5 degrees, 90 to 157.5 degrees, 180 to 247.5 degrees, and 270 to 337.5 degrees, respectively, in the circumferential direction in the cylindrical surface projection development, and the radial projections of the four grooves 611 may be in the ranges of 67.5 to 90 degrees, 157.5 to 180 degrees, 247.5 to 270 degrees, and 337.5 to 360 degrees, respectively, in the circumferential direction in the cylindrical surface projection development. Each cam portion 612 includes a first engagement surface 613 and a second engagement surface 614. In the longitudinal direction of the cam sleeve 610, the starting point 613a of the first engagement surface 613 is closer to the closed end of the cam sleeve 610 than the ending point 613b thereof, and likewise the starting point 614a of the second engagement surface 614 is closer to the closed end of the cam sleeve 610 than the ending point 614b thereof, the starting point 613a of the first engagement surface 613 being located on the wall of the adjacent groove 611, the ending point 613b of the first engagement surface 613 being aligned with the starting point 614a of the second engagement surface 614, the ending point 614b of the second engagement surface 614 being closer to the closed end of the cam sleeve 610 and on the wall of the other adjacent groove 611 with respect to the ending point 614b of the first engagement surface 614. Thus, for each cam portion 612, the first engagement surface 613 and the second engagement surface 614 together constitute a cam profile surface of the cam portion.
Referring to fig. 7, a structure of a push rod sleeve 620 in the locking mechanism 600 shown in fig. 5 is schematically shown. As shown in fig. 7, and referring to fig. 5 and 9 in combination, push rod sleeve 620 includes a push rod 621 and a sleeve 622. A push rod 621 is provided at one end of the sleeve 622 and extends in the longitudinal direction of the sleeve 622. The push rod 621 may be fixedly coupled to the second touch circuit board 322 of the second panel assembly 320 so that the second operating surface 120 of the second panel assembly 320 can be positioned and maintained in the first position or the second position, respectively, under the influence of the locking mechanism 600. Sleeve 622 has a hollow cylindrical shape such that it can accommodate both cam lever 630 and cam sleeve 610, as shown in fig. 7. The sleeve 622 is closed at one end thereof where the push rod 621 is disposed and open at the opposite end thereof. Four keys 623 are uniformly provided on the outer wall of the sleeve 622 in the circumferential direction. The keys 623 are in one-to-one correspondence with the grooves 611 on the cam sleeve 610 such that when the push rod sleeve 620 is received in the cam sleeve 610, the keys 623 are inserted into one of the corresponding grooves 611. Thus, as a non-limiting example, as shown in fig. 9, the radial projections of the four keys 623 may be disposed in the cylindrical projection spread view in ranges of 67.5 to 90 degrees, 157.5 to 180 degrees, 247.5 to 270 degrees, and 337.5 to 360 degrees, respectively, in the circumferential direction. The open end of the sleeve 622 is provided with eight teeth 624 uniformly in the circumferential direction, each tooth 624 including a first inclined surface 624a and a second inclined surface 624b, and a tooth tip 624c formed by the intersection of the first inclined surface 624a and the second inclined surface 624 b. As a non-limiting example, as shown in fig. 9, the radial projection of each tooth 624 has a range of 45 degrees in the circumferential direction in the cylindrical projection expanded view, and the radial projection of the tooth tip 624c of each tooth 624 corresponding to a groove 611 falls within the range of the radial projection of that groove 611, for example, may be located on the center line of the radial projection of the corresponding groove 611.
Referring to fig. 8, the structure of the cam lever 630 in the locking mechanism 600 shown in fig. 5 is schematically shown. As shown in fig. 8, and referring to fig. 5 and 9 in combination, the cam rod 630 may have a cylindrical shape that may be received within the sleeve 622 of the push rod sleeve 620. One end of the cam lever 630 is provided with four sliders 631 extending in the longitudinal direction thereof and uniformly distributed in the circumferential direction thereof. Each slide 631 can be inserted into a corresponding slot 611 such that, as a non-limiting example, the radial projection of each slide 631 has a range of 22.5 degrees in the circumferential direction in a cylindrical projection spread view, and adjacent slides 631 are spaced apart by a distance of 67.5 degrees, as shown in fig. 9. Each slide 631 includes a sloped slide engagement surface 632. The slider engagement surface 632 is capable of contacting and sliding along the corresponding first engagement surface 613 or second engagement surface 614 of the cam portion 612. Further, as shown in fig. 6, the radial thickness of each slider 631 is set such that the slider engagement surface 632 thereof can be brought into contact with the corresponding tooth 624, and the first engagement surface 613 or the second engagement surface 614 of the corresponding cam portion 612, respectively.
Referring back to fig. 5, a spring 640 is disposed between the closed end of the cam sleeve 610 and the end of the cam lever 630 where the slider 631 is disposed. The spring 640 may be any suitable resilient member configured to exert pressure on the cam lever 630.
The locking mechanism 600 formed by assembling the cam sleeve 610, the push rod sleeve 620, the cam lever 630, and the spring 640 as shown in fig. 5 is capable of positioning and holding the second panel assembly 320, and thus the second operating surface 120, in the first position or the second position.
Referring to fig. 10A to 10E, the principle of operation of the locking mechanism 600 shown in fig. 5 is schematically shown in the form of a cylindrical projection development. For clarity, only radial projections of the following sections on the cylindrical surface are shown in fig. 10A to 10E: cam portion 612 of cam sleeve 610 and respective first engagement surface 613, second engagement surface 614; key 623 and teeth 624 of push rod sleeve 620; and one slider 631 of the cam lever 630.
Referring to fig. 3A, 3B, 5 to 9 in combination, as shown in fig. 10A, the slider 631 of the cam lever 630 is located in the corresponding groove 611 of the cam sleeve 610 and the slider engagement surface 632 is in contact with the second inclined surface 624B of the corresponding tooth 624 in the push rod sleeve 620. At this time, the push rod 621 of the push rod sleeve 620 makes the stopper 3221 of the second touch circuit board 322 of the second panel assembly 320 abut against the first touch circuit board 312 of the first panel assembly 310 under the action of the spring 340, thereby maintaining the second operation surface 120 in the first position and preventing the accidental depression of the key 313.
As shown in fig. 10B, when the user presses the second panel assembly 320, the push rod sleeve 620 moves in the direction D1 shown in the drawing under the action of the push rod 621, and neither the push rod sleeve 620, nor thus the teeth 624 of the push rod sleeve 620, can rotate in the circumferential direction due to the keys 623. Tooth 624 urges slider 631 in direction D1 shown in the figures. When the tooth 624 pushes the slider 631 to the position shown in fig. 10B, the slider 631 can be rotated in the direction D2 shown in the drawing by the second inclined surface 624B of the tooth 624 since the slider 631 is disengaged from the groove 611.
As shown in fig. 10C, the user is no longer pressing the second panel assembly 320 at this point, and thus the push rod sleeve 620 is no longer pushing the slider 631 in the direction D1 shown in fig. 10B. Since the slide 631 has been rotated in the direction D2 from the position shown in fig. 10B, when the push rod sleeve 620 teeth 624 no longer push the slide 631, the slide 631 will contact the first engagement surface 613 of the cam part 612 under the action of the spring 340 and slide along the first engagement surface 613 until the termination point 613B of the first engagement surface 613 is reached. Thereby, the lock mechanism 600 can hold the second operation surface 120 in the second position. As can be seen from fig. 10C, the slider 631 has now been rotated 45 degrees in the circumferential direction compared to the initial position shown in fig. 10A. Also, the teeth 624 of the push rod sleeve 620 remain in contact with the slide 631 at this time, but do not actuate the slide 631.
As shown in fig. 10D, when the user presses the second panel assembly 320 again, the push rod sleeve 620 moves in a direction D1 shown in the drawing by the push rod 621. Tooth 624 again pushes slider 631 in direction D1 as shown. When the tooth 624 pushes the slider 631 to the position shown in fig. 10D, the slider 631 starts to rotate in the direction D2 shown in the figure by the second inclined surface 624b of the tooth 624 since the slider 631 has escaped from the restriction of the cam portion 612.
As shown in fig. 10E, the user does not press the second panel assembly 320 any more at this time, and thus the cam lever 630 moves in a direction opposite to the direction D1 shown in fig. 10D under the action of the spring 340. At this time, since the slider 631 has been rotated in the direction D2, when the slider 631 comes into contact with the second engagement surface 614 of the cam portion 612, the slider 631 slides along the second engagement surface 6143 under the action of the spring 340 until reentering the adjacent groove 611 and coming into contact with the corresponding tooth 624. Thus, the locking mechanism 600 is able to reposition and hold the second operating surface 120 in the first position. As can be seen in fig. 10E, the slider 631 has now been rotated 90 degrees in the circumferential direction as compared to the initial position shown in fig. 10A.
Thereafter, when the user again presses the second panel assembly 320 again, the locking mechanism 600 will repeat the operation process of fig. 10A to 10E. Thus, by the locking mechanism 600, the second panel assembly 320, and thus the second operation surface 120, can be positioned and held in the first position or the second position based on the pressing operation of the second panel assembly 320 by the user.
It should be appreciated that fig. 5-9 and 10A-10E illustrate only one exemplary embodiment of locking mechanism 600, however, it will be appreciated from the teachings of the present disclosure that locking mechanism 600 may include any other suitable arrangement of cam sleeve 610, push rod sleeve 620, cam lever 630 and spring 640, so long as it is capable of performing the functions described above. As a non-limiting example, n grooves 611 extending in the longitudinal direction thereof and uniformly distributed in the circumferential direction thereof may be provided on the inner wall of the cam sleeve 610, and n may be an integer greater than 0. In this case, correspondingly, n cam portions 612 extending in the longitudinal direction thereof and alternately distributed with n grooves in the circumferential direction thereof may be further provided on the inner wall of the cam sleeve 610. At this time, k keys 623 may be provided on the sleeve 622 of the push rod sleeve 620, the k keys 623 extending in the longitudinal direction of the push rod sleeve 620 and being capable of being inserted into the k grooves 611 of the cam sleeve 610, respectively, so that k is an integer greater than 0 and less than or equal to n. Further, the open end of the sleeve 622 may be provided with 2n teeth 624, and the cam lever 630 may be provided with n sliders 631 extending in the longitudinal direction thereof and uniformly distributed in the circumferential direction thereof. With the cam sleeve 610, the push rod sleeve 620, and the cam lever 630 in this case as described above, along this circumferential direction, the radial projection of the tooth tip 624c of the 2 n-th tooth 624 is located within the range of the radial projection of the n-th groove 611, and the radial projection of the tooth tip 624c of the 2 n-1-th tooth 624 falls within the range of the radial projection of the first engagement surface 613 of the n-th cam part 612.
It should also be appreciated that friction may be provided between the cam sleeve 610 and the push rod sleeve 620, or between the push rod sleeve 620 and the cam rod 630, as non-limiting examples, such that the push rod sleeve 620 is able to move relative to the cam sleeve 610 when there is an actuation operation of the push rod sleeve 620, and the push rod sleeve 620 will remain stationary due to the presence of friction when there is no actuation operation of the push rod sleeve 620. In this manner, when the user presses the second panel assembly 320, the push rod sleeve 620 can move relative to the cam sleeve 610, and when the slider 631 engages the first engagement surface 613 of the cam portion 612, thereby maintaining the second operating surface 320 in the second position, the push rod sleeve 620 can be held in place by friction, thereby preventing the second operating surface 320 from being accidentally disengaged from the second position. It should be appreciated that the above-described friction effect may be achieved by bringing the inner wall of the cam sleeve 610 into contact with the outer wall of the push rod sleeve 620, or may be achieved by providing elastic retaining means (e.g., elastic pieces) on the inner wall of the cam sleeve 610 or the outer wall of the push rod sleeve 620. Similarly, the above friction effect may be achieved by bringing the inner wall of the push rod sleeve 620 into contact with the cam lever 630, or may be achieved by providing an elastic holding means (e.g., an elastic sheet) on the inner wall of the push rod sleeve 620 or on the cam lever 630. The present disclosure is not limited in how the above friction effects are achieved between these components.
In another non-limiting example, the push rod 621 of the push rod sleeve 620 may be configured such that the push rod 621 abuts the first touch circuit board 312 when the second operating surface 120 is in the first position. Thus, the push rod 621 can support the first panel assembly 310 while also preventing accidental pressing of the key 313 at this time. In this way, the second touch circuit board 322 may not be provided with the stopper 3221, thereby avoiding a special-shaped structure, thereby making its design and manufacture easy.
Referring to fig. 11, a structure of a manipulation panel is schematically shown according to another exemplary embodiment of the present disclosure. The steering panel shown in fig. 11 is substantially identical in structure to the steering panel shown in fig. 3A and 3B, except that the positioning and retaining device 330 is implemented as a shape memory alloy actuation device 700. As shown in fig. 11, the shape memory alloy actuation apparatus 700 includes a spring 710, a shape memory alloy wire 720, and a control apparatus 730. The spring 710 is fixedly coupled to the second touch circuit board 322 to apply pressure thereto. The shape memory alloy wire 720 is fixedly connected to the second touch circuit board 322. As a non-limiting example, shape memory alloy wire 720 may be, for example, a nickel titanium (TiNi) shape memory alloy wire that contracts when energized. Thus, as shown in FIG. 11, when the control device 730 does not energize the shape memory alloy wire 720, the second panel assembly 320 abuts the first panel assembly 310 under the influence of the spring 710 to maintain the second operating surface 120 in the first position. When a key operation is required, the control means 730 energizes the shape memory alloy wire 720, so that the shape memory alloy wire 720 contracts, pulling the second panel assembly 320 and, together with the spring 710, positioning and holding the second operating surface 120 in the second position.
It should be understood that any other form of shape memory alloy actuation device is possible, such as, but not limited to, a shape memory alloy based drive rod or a micro motor, provided that it is capable of performing the above-described functions. The present disclosure is not limited in this regard.
Referring to fig. 12, a method of operating a dashboard according to an exemplary embodiment of the present disclosure is schematically illustrated in the form of a flowchart. It should be understood that the manipulation panel to which the method shown in fig. 12 is applied includes a locking mechanism having a structure as shown in fig. 5 to 9 and an operation principle as shown in fig. 10A to 10E. The lock mechanism enables the operation panel to be positioned and held in the first position or the second position by only a pressing operation. As shown in fig. 12, method 900 includes steps 910, 920, 930, and 940:
pressing the second panel assembly to position the second operative surface in the first position to the second position at step 910;
releasing the second panel assembly and causing the second operative surface to be held in the second position at step 920;
pressing the second panel assembly, causing the second operative surface to be released from the second position, step 930;
At step 940, the second panel assembly is released such that the second operative surface is again positioned and maintained in the first position.
The above steps 910, 920, 930, and 940 may be repeatedly performed, thereby enabling the second operation surface 120 to be alternately positioned and maintained at the first position or the second position, thereby enabling the manipulation panel to be correspondingly applied to the touch application scene or the key application scene.
Referring to fig. 13, a control method applied to a manipulation panel according to an exemplary embodiment of the present disclosure is schematically shown in the form of a flowchart. It should be understood that the control panel to which the control method shown in fig. 13 is applied may include a chip and a state detection key. As a non-limiting example, the dashboard may include the chip 400 and status detection keys 340 shown in fig. 4. As shown in fig. 13, the control method 1000 includes steps 1010 and 1020:
in step 1010, when the second operation surface is positioned and maintained at the first position, releasing the state detection key to indicate that the control panel is in a touch application scene, and making the chip detect a touch operation on the control panel;
In step 1020, when the second operation surface is positioned and maintained at the second position, the state detection key is pressed to indicate that the manipulation panel is in a key application scene, and the chip is caused to detect a key operation on the manipulation panel.
Therefore, with the control method 1000, based on the state of the state detection key, i.e. the released state or the pressed state, the chip of the control panel can detect the current application scenario of the control panel, and perform corresponding operations. As a non-limiting example, when in a touch application scenario, the chip of the dashboard may detect a touch operation to the dashboard; when the key application scene is in, the chip of the control panel can detect the key operation on the control panel. In some exemplary embodiments, when in a touch application scenario, the chip of the dashboard may ignore key operations to the dashboard; when the key application scene is in, the chip of the control panel can ignore the touch operation of the control panel.
