Description

Technical Field

[0001] The utility model relates to the technical field of electronic equipment, and in particular to a touch control device and an electronic equipment. Background Art

[0002] Electronic devices are usually equipped with touch devices, which are used to sense the user's sliding, clicking and other actions, and provide vibration feedback to the user's operation in a timely manner. At present, the touch device generally uses a pressure detection component and a linear vibration motor to complete the vibration feedback. However, due to the high cost and complex installation of the linear vibration motor, the cost of the touch device is high. Utility Model Content

[0003] In view of the above, it is necessary to provide a touch control device and an electronic device to reduce the cost of the touch control device.

[0004] The present invention provides a touch control device, comprising:

[0005] A substrate assembly, comprising a touch member and a circuit board mounted on the touch member;

[0006] A pressure detection component, comprising a pressure detection member and a flexible member, wherein the pressure detection member is disposed on the circuit board and is used to detect pressure, and the flexible member is disposed on a side of the pressure detection member away from the circuit board;

[0007] A vibration component includes a mounting part, a magnetic part and a coil, wherein the mounting part is connected to the flexible part and is arranged on a side of the flexible part away from the pressure detection part, the coil is wound on the mounting part, the coil is used to generate an alternating magnetic field when alternating current is passed through, the magnetic part is arranged on the circuit board corresponding to the coil, and the magnetic part is used to drive the circuit board and the touch part to vibrate under the action of the alternating magnetic field.

[0008] In the above touch control device, after the touch member is subjected to pressure, the pressure can be transmitted to the pressure detection member through the circuit board. After the pressure detection member detects the pressure or the detected pressure exceeds a certain threshold, the coil passes alternating current and generates an alternating magnetic field. Under the action of the alternating magnetic field, the magnetic member drives the circuit board and the touch member to vibrate, thereby realizing vibration feedback of the pressure exerted on the touch member. Therefore, in the above touch control device, vibration feedback is realized by the cooperation of the pressure detection member, the magnetic member and the coil, and the structure is simple and the manufacturing cost is low. In addition, the flexible member forms a flexible support for the mounting member, which can reduce the damage of the pressure to the mounting member, thereby reducing the use cost of the touch control device. Furthermore, the stacking arrangement of the pressure detection member, the flexible member and the mounting member is conducive to the rapid assembly of the touch control device, thereby reducing the assembly cost.

[0009] In some embodiments, the flexible member and the mounting member are both plate-shaped structures, the circuit board, the touch member, the flexible member and the mounting member are parallel to each other, and the central axis of the coil is parallel to the circuit board.

[0010] Therefore, the mounting member is parallel to the circuit board and the flexible member, which can reduce the overall thickness of the vibration assembly, thereby facilitating the thinning and lightweight setting of the touch device. In addition, the central axis of the coil is parallel to the circuit board, which can reduce the influence of the number of turns of the coil on the thickness of the vibration assembly, further facilitating the thinning and lightweight setting of the touch device.

[0011] In some embodiments, the pressure detection components are multiple groups, and the multiple groups of pressure detection components are arranged on the same side of the circuit board. The multiple pressure detection parts in the multiple groups of pressure detection components are symmetrically arranged relative to the center of the circuit board.

[0012] Therefore, multiple groups of pressure detection components can detect the force on the circuit board at multiple points at the same time to achieve full-area pressing of the touch component, and the symmetrically arranged multiple pressure detection components can improve the uniformity of the pressure received by the pressure detection component, which is beneficial to improving the accuracy of the vibration feedback of the vibration component.

[0013] In some embodiments, the circuit board has a first end and a second end that are arranged opposite to each other, and among the multiple groups of pressure detection components, a part of the pressure detection components are arranged at the first end, and another part of the pressure detection components are arranged at the second end. The mounting member includes a mounting body and a connecting body respectively arranged at the first end and the second end, the mounting body is connected to the flexible member located at the first end, the coil is wound on the mounting body, the connecting body is connected to the flexible member located at the second end, and the magnetic member is arranged between the mounting body and the connecting body.

[0014] Therefore, the separately arranged mounting body and connecting body can reduce the area of ​​the touch device occupied by the mounting member, which is conducive to the lightweight and thin setting of the touch device.

[0015] In some embodiments, the mounting body comprises:

[0016] A mounting portion, connected to the corresponding flexible member and spaced apart from the magnetic member;

[0017] The extension part is connected to the mounting part and is located between the mounting part and the magnetic member, and the coil is sleeved on the extension part.

[0018] Therefore, the connected mounting portion and the extending portion make the mounting body roughly T-shaped, so that the mounting body can avoid occupying additional area of ​​the circuit board while satisfying the connection between the flexible member and the coil.

[0019] In some embodiments, the mounting portion and the connecting body are respectively provided with mounting holes on a side facing away from the circuit board, and the mounting holes are used to connect external components to fix the touch control device.

[0020] Therefore, the mounting hole is helpful to fix the touch control device to the external component.

[0021] In some embodiments, the circuit board has a first end and a second end that are relatively set. Among the multiple groups of pressure detection components, a part of the pressure detection components are arranged at the first end, and another part of the pressure detection components are arranged at the second end. The vibration components are divided into two groups, and the two groups of vibration components are respectively arranged at the first end and the second end, and the two groups of vibration components are symmetrically arranged relative to the center of the circuit board.

[0022] Therefore, the two sets of vibration components arranged symmetrically can improve the accuracy of the vibration feedback of the touch device.

[0023] In some embodiments, two ends of the pressure detection component are respectively connected to the circuit board, and the middle portion of the pressure detection component is gap-matched with the circuit board, and the flexible component is arranged in the middle portion of the pressure detection component.

[0024] Therefore, by rationally arranging the position of the flexible member relative to the pressure detection member, it is helpful to improve the accuracy of the pressure detection member in detecting the pressure.

[0025] In some embodiments, the touch control device further includes:

[0026] The ferrite is arranged on the circuit board and is located on a side of the magnetic component away from the coil.

[0027] Therefore, the ferrite can stabilize the magnetic field where the touch device is located, which is beneficial to improving the stability of the vibration feedback of the touch device.

[0028] The present invention also provides an electronic device, including:

[0029] The touch control device described in the above embodiment;

[0030] The housing is connected to the touch element and the circuit board respectively.

[0031] In the above electronic device, vibration feedback is achieved by the cooperation of the pressure detection member, the magnetic member and the coil, which has a simple structure and low manufacturing cost. In addition, the flexible member forms a flexible support for the mounting member, which can reduce the damage to the mounting member caused by pressure, thereby reducing the use cost of the electronic device. Furthermore, the stacking arrangement of the pressure detection member, the flexible member and the mounting member is conducive to the rapid assembly of the electronic device, thereby reducing the assembly cost.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0062] The following is a detailed description of various embodiments of the present invention in conjunction with the accompanying drawings.

[0063] See also Figure 1 and Figure 2 The embodiment of the utility model provides a touch device 100, including a substrate assembly 110, a pressure detection assembly 120 and a vibration assembly 130. The substrate assembly 110 includes a touch member 111 and a circuit board 112 mounted on the touch member 111, the circuit board 112 is arranged opposite to the touch member 111, the pressure detection assembly 120 includes a pressure detection member 121 and a flexible member 122, the pressure detection member 121 is arranged on the circuit board 112 and used to detect pressure, and the flexible member 122 is arranged on the side of the pressure detection member 121 away from the circuit board 112. The vibration component 130 includes a mounting member 131, a magnetic member 132 and a coil 133. The mounting member 131 is connected to the flexible member 122, and the mounting member 131 is arranged on the side of the flexible member 122 away from the pressure detection member 121. The coil 133 is wound on the mounting member 131. The coil 133 is used to generate an alternating magnetic field when alternating current is passed through. The magnetic member 132 is arranged on the circuit board 112 corresponding to the coil 133. The magnetic member 132 is used to drive the circuit board 112 and the touch member 111 to vibrate under the action of the alternating magnetic field.

[0064] It should be noted that the touch member 111 may be a touch screen used in an electronic device, and the circuit board 112 may be a flexible circuit board, a rigid circuit board, or a rigid-flexible board. The flexible member 122 may be a member made of a material such as silicone. In addition, when the touch device 100 cooperates with other components to form an electronic device, the mounting member 131 is also connected to the other components.

[0065] Furthermore, the pressure detection member 121 may be connected to the circuit board 112 via an adhesive member. The adhesive member may be a cured glue or a double-sided adhesive, and may be attached to a part or all of the pressure detection member 121 .

[0066] In the above touch control device 100, after the touch member 111 is subjected to pressure, it can be transmitted to the pressure detection member 121 through the circuit board 112. After the pressure detection member 121 detects the pressure or the detected pressure reaches a certain threshold, the coil 133 passes alternating current and generates an alternating magnetic field. Under the action of the alternating magnetic field, the magnetic member 132 drives the circuit board 112 and the touch member 111 to vibrate, thereby realizing vibration feedback of the pressure on the touch member 111. Therefore, in the above touch control device 100, vibration feedback is realized by the cooperation of the pressure detection member 121, the magnetic member 132 and the coil 133, which has a simple structure and low manufacturing cost. In addition, the flexible member 122 forms a flexible support for the mounting member 131, which can reduce the damage of the mounting member 131 caused by the pressure, thereby reducing the use cost of the touch control device 100. Furthermore, the pressure detection member 121, the flexible member 122 and the mounting member 131 are stacked, which is conducive to the rapid assembly of the touch control device 100, thereby reducing the assembly cost.

[0067] See also Figure 2 In some embodiments, the pressure detection element 121 is electrically connected to the circuit board 112 , and the coil 133 is electrically connected to the circuit board 112 .

[0068] In this embodiment, the coil 133 is welded on the circuit board 112 through the wires drawn out of the coil 133. The circuit board 112 has a processing circuit. When the pressure detection element 121 detects pressure, an electrical signal is generated and transmitted to the processing circuit. The processing circuit transmits alternating current to the coil 133 based on the received electrical signal. The number of turns of the coil 133 can be adjusted in time based on the required strength of the alternating magnetic field.

[0069] Therefore, the coil 133 and the pressure detection element 121 are electrically connected through the circuit board 112. Compared with the coil 133 being directly electrically connected to the pressure detection element 121 through a wire, the wire can avoid occupying the surface area of ​​the circuit board 112, which is beneficial to reducing the overall thickness of the touch device 100.

[0070] In other embodiments, the coil 133 and the pressure detecting element 121 may be respectively connected to the same power source or controller to enable the coil 133 and the pressure detecting element 121 to be energized.

[0071] In some embodiments, the flexible member 122 and the mounting member 131 are both plate-like structures, the circuit board 112 , the touch member 111 , the flexible member 122 and the mounting member 131 are parallel to each other, and the central axis of the coil 133 is parallel to the circuit board 112 .

[0072] Therefore, the mounting member 131 is parallel to the circuit board 112 and the flexible member 122, which can reduce the overall thickness of the vibration assembly 130, thereby facilitating the thinning and lightweight configuration of the touch control device 100. In addition, the central axis of the coil 133 is parallel to the circuit board 112, which can reduce the effect of the number of turns of the coil 133 on the thickness of the vibration assembly 130, further facilitating the thinning and lightweight configuration of the touch control device 100.

[0073] In some embodiments, there are multiple groups of pressure detection components 120, and the multiple groups of pressure detection components 120 are arranged on the same side of the circuit board 112. The multiple pressure detection parts 121 in the multiple groups of pressure detection components 120 are symmetrically arranged relative to the center of the circuit board 112.

[0074] In this embodiment, there are four groups of pressure detection components 120, and the four groups of pressure detection components 120 are respectively arranged at four end corners of the circuit board 112. In other implementations, there may be three, five or more groups of pressure detection components 120.

[0075] Therefore, multiple groups of pressure detection components 120 can simultaneously detect the force on the circuit board 112 at multiple points to achieve full-area pressing of the touch component 111, and the symmetrically arranged multiple pressure detection components 121 can improve the uniformity of the pressure received by the pressure detection component 120, which is beneficial to improving the accuracy of the vibration feedback of the vibration component 130.

[0076] See also Figure 2 In some embodiments, the circuit board 112 has a first end 112a and a second end 112b that are relatively disposed. Among the multiple groups of pressure detection components 120, a portion of the pressure detection components 120 are disposed at the first end 112a, and another portion of the pressure detection components 120 are disposed at the second end 112b.

[0077] See also Figure 2 In this embodiment, the mounting member 131 includes a mounting body 1311 and a connecting body 1312 respectively arranged at the first end 112a and the second end 112b, the mounting body 1311 is connected to the flexible member 122 located at the first end 112a, the coil 133 is wound on the mounting body 1311, the connecting body 1312 is connected to the flexible member 122 located at the second end 112b, and the magnetic member 132 is arranged between the mounting body 1311 and the connecting body 1312.

[0078] Therefore, the separately arranged installation body 1311 and the connecting body 1312 can reduce the area of ​​the touch device 100 occupied by the installation component 131 , which is beneficial to the lightweight and thin configuration of the touch device 100 .

[0079] In other embodiments, there may be two groups of vibration components 130, which are respectively disposed at the first end 112a and the second end 112b, and the two groups of vibration components 130 are symmetrically disposed relative to the center of the circuit board 112. The two symmetrically disposed groups of vibration components 130 can improve the accuracy of the vibration feedback of the touch device 100.

[0080] See also Figure 1 and Figure 2 In some embodiments, the mounting body 1311 includes a mounting portion 1311a and an extension portion 1311b. The mounting portion 1311a is connected to the corresponding flexible member 122 and is spaced apart from the magnetic member 132, the extension portion 1311b is connected to the mounting portion 1311a and is located between the mounting portion 1311a and the magnetic member 132, and the coil 133 is sleeved on the extension portion 1311b.

[0081] In this embodiment, the mounting portion 1311a is a bent structure, and there are two extension portions 1311b. Correspondingly, there are two coils 133, and each extension portion 1311b is sleeved with a coil 133. In other embodiments, there may be one, three or more extension portions 1311b and coils 133, as long as the number of extension portions 1311b and coils 133 is the same and corresponds one to one.

[0082] Therefore, the connected mounting portion 1311 a and the extending portion 1311 b make the mounting body 1311 substantially T-shaped, so that the mounting body 1311 can avoid occupying additional area of ​​the circuit board 112 while satisfying the connection between the flexible member 122 and the coil 133 .

[0083] In this embodiment, the mounting portion 1311 a and the two extending portions 1311 b are an integrated structure, which is beneficial to simplifying the processing of the mounting body 1311 and reducing the manufacturing cost of the mounting body 1311 .

[0084] See also Figure 2 In some embodiments, a mounting hole 131 a is respectively formed on the mounting portion 1311 a and the side of the connecting body 1312 facing away from the circuit board 112 , and the mounting hole 131 a is used to connect external components to fix the touch device 100 .

[0085] In this embodiment, the mounting hole 131a is a threaded hole, and there are two mounting holes 131a on the mounting portion 1311a and the connecting body 1312. In other embodiments, the mounting hole 131a may also be other structures that can match external components, and the mounting holes 131a on the mounting portion 1311a and the connecting body 1312 may be one, three or more.

[0086] Therefore, the mounting hole 131 a is helpful for fixing the touch control device 100 to an external component.

[0087] See also Figure 2 In some embodiments, both ends of the pressure detection component 121 are respectively connected to the circuit board 112 , and the middle of the pressure detection component 121 is gap-matched with the circuit board 112 , and the flexible component 122 is arranged in the middle of the corresponding pressure detection component 121 .

[0088] Therefore, by properly arranging the position of the flexible member 122 relative to the pressure detection member 121 , it is helpful to improve the accuracy of the pressure detection by the pressure detection member 121 .

[0089] In some embodiments, the magnetic member 132 and the circuit board 112, the flexible member 122 and the mounting member 131, and the flexible member 122 and the pressure detection member 121 are all connected via an adhesive member 140. The adhesive member 140 may be glue or a double-sided tape.

[0090] Therefore, by connecting the above components through the adhesive 140 , the manufacturing cost of the touch device 100 can be reduced.

[0091] See also Figure 1 and Figure 2 The touch device 100 further includes a ferrite 150. The ferrite 150 is disposed on the circuit board 112 and is located on the side of the magnetic member 132 away from the coil 133. Therefore, the ferrite 150 can stabilize the magnetic field where the touch device 100 is located, which is beneficial to improving the stability of the vibration feedback of the touch device 100.

[0093] In some embodiments, the electronic device 1000 further includes an electrical component 300. The electrical component 300 is mounted on the side of the circuit board 112 away from the touch member 111 and is surrounded in the middle area of ​​the circuit board 112 to form a position-avoiding groove 300a. The ferrite 150 is received in the position-avoiding groove 300a to cover the inductive device disposed on the circuit board 112.

[0094] In the electronic device 1000, the pressure detection member 121, the magnetic member 132 and the coil 133 cooperate to realize vibration feedback, which has a simple structure and low manufacturing cost. In addition, the flexible member 122 forms a flexible support for the mounting member 131, which can reduce the damage of the mounting member 131 caused by pressure, thereby reducing the use cost of the electronic device 1000. Furthermore, the pressure detection member 121, the flexible member 122 and the mounting member 131 are stacked, which is conducive to the rapid assembly of the electronic device 1000, thereby reducing the assembly cost.
