Description

Technical Field

[0001] The present invention relates to the field of touch panels, and in particular to a touch panel bracket, a touch panel and an electronic input device. Background Art

[0002] The working principle of the touchpad is based on pressure sensing and circuit triggering. When the user touches the touch panel with a finger or a stylus, the panel will be partially deformed. This deformation is transmitted to the structure used to fix and support the touch panel through the internal bracket, and then touches the switch on the back of the PCB board. After the switch is touched, the touch circuit is started to convert the touch pressure signal into an electrical signal for processing, thereby realizing human-computer interaction. However, the common three-point touch mode requires pressing control at a specified position to achieve the control effect, which leads to inconvenience in use.

[0003] For example: the Chinese patent disclosed "a touch bracket and a touch panel including the same", its specification discloses: the invention name is a patent application for a parallel motion touch panel, which is provided with a cover with a touch function (a panel for direct contact with human fingers), and the cover includes four side edges. When in use, only the side edges can be touched to get a response from the touch circuit, which is the common three-point touch mode; with this structure, it is impossible to touch any point on the cover to get a response from the touch circuit, so there are inconveniences in use; the above patent can prove the defects of the prior art.

[0019] In the scheme of this application:

[0020] 1. In order to solve the problem in the prior art that it is impossible to get a response from the touch circuit by touching or pressing any point on the cover, the present application supports and installs the spring sheet by setting a support frame, and sets a contact base at the bottom of the spring sheet at the center position of the support frame, and sets a PCB board on the top of the spring sheet, and sets a touch panel on the top of the PCB board, and sets a control component in the middle of the spring sheet, and makes the limiting ring of the control component clamped on the top of the spring sheet, and makes the PCB board stand above the limiting ring, when pressing any position of the touch panel, the bottom PCB board is squeezed, and the control component moves down and contacts with the contact base at the bottom so that the touch circuit responds, and by setting the touch panel in partitions, the cursor movement can be controlled when the touch panel surface is touched, so that the touch circuit can be turned on by touching or pressing any point of the touch panel, and the movement of the cursor can be controlled by touching;

[0034] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0035] As described in the background art, it is impossible to obtain a response from the touch circuit by pressing any point on the cover.

[0036] In order to solve this technical problem, the present invention provides a touch panel bracket, a touch panel and an electronic input device, which are applied to a computer touch panel.

[0037] Specifically, please refer to Figure 1-Figure 8 , the touchpad bracket specifically includes:

[0038] The support frame 1 has a spring 103 fixedly mounted on the bottom of the support frame 1. A pair of reinforcing plates 104 are symmetrically arranged on the top of the spring 103. The reinforcing plates 104 are adapted to the shape of the spring 103. A PCB board 101 is arranged on the top of the reinforcing plate 104. A touch panel 102 is attached to the top of the PCB board 101. The PCB board 101 is an elastic sheet. Two pairs of guide bolts 105 are installed on the opposite sides of the middle of the spring 103. A return spring 106 is arranged between the top of the guide bolt 105 and the bottom of the spring 103. The guide bolt 105 supports the spring 103 upwards through the return spring 106. A control assembly 2 is provided in the middle of the spring 103. The control assembly 2 includes a ball switch 201 and a limit ring 202. The limit ring 202 is clamped in the middle of the top of the spring 103. A contact base 109 is provided at the bottom of the ball switch 201. The ball switch 201 is located just above the contact base 109 and clamped on the inner side of the contact base 109. When the ball switch 201 is subjected to pressure, it descends and contacts the bottom of the contact base 109, making the touch circuit conductive.

[0039] By pressing any point on the surface of the touch panel 102, pressure is generated on the PCB board 101 at the bottom, and the pressure is transmitted to the reinforcing plate 104, and pressure is generated on the limit ring 202 in the middle of the spring 103 through the PCB board 101, so that the ball switch 201 moves downward and contacts and conducts with the contact base 109 at the bottom. After the conduction is completed, the reset spring 106 at the top of the guide bolt 105 supports the spring 103 when it is loosened, and resets the spring 103.

[0040] The touch panel bracket provided by the present invention solves the problem in the prior art that it is impossible to obtain a response of the touch circuit by touching and pressing any point on the cover. The present application supports and installs the spring piece 103 by setting a support frame 1, and sets a contact base 109 at the bottom of the spring piece 103 at the center position of the support frame 1, and sets a PCB board 101 on the top of the spring piece 103, and sets a touch panel 102 on the top of the PCB board 101, and sets a control component 2 in the middle of the spring piece 103, and The limiting ring 202 of the control component 2 is clamped on the top of the spring 103, and the PCB board 101 is placed above the limiting ring 202. When any position of the touch panel 102 is pressed, the PCB board 101 at the bottom is squeezed, and the control component 2 moves down and contacts the contact base 109 at the bottom to make the touch circuit respond. At the same time, it can move when the surface of the touch panel 102 is touched, so that the touch circuit can be turned on by pressing any point of the touch panel 102, and the movement of the cursor can be controlled by touching.

[0041] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0042] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0044] Example 1, please refer to Figure 6-Figure 8 A touch panel bracket, wherein a top cover 203 is sleeved on the top of a ball switch 201, a guide ring 204 is fixedly connected to the bottom of the top cover 203, and the guide ring 204 is vertically slidably engaged in the inner cavity of the ball switch 201, the top cover 203 is moved downward and sleeved in the inner cavity of the ball switch 201 and is lower than the surface of the touch panel 102, and the top cover 203 is moved upward to form a sphere with the ball switch 201, a telescopic sleeve rod 205 is fixedly installed on the top of the inner cavity of the top cover 203, and a magnetic ball 208 is fixedly connected to the bottom of the telescopic sleeve rod 205, and the magnetic ball 208 is The weighted sphere, the electromagnetic plate 209 is fixedly installed at the bottom of the inner cavity of the ball switch 201, and the guide rod 210 is fixedly installed on the top of the electromagnetic plate 209. The magnetic ball 208 and the telescopic sleeve rod 205 sleeve the guide rod 210 in the middle. A tension spring 207 is provided in the middle of the inner cavity of the guide rod 210. The top of the tension spring 207 is fixedly connected to the top of the inner cavity of the top cover 203, and the bottom of the tension spring 207 is fixedly connected to the top of the electromagnetic plate 209. The tension spring 207 pulls the top cover 203 downward and makes the magnetic ball 208 fit on the top of the electromagnetic plate 209.

[0045] The top cover 203 extends from the top of the ball switch 201 to form a sphere. At this time, the rotation of the three-dimensional graph can be controlled by rotating the ball switch 201 and the top cover 203. At the same time, when the graph needs to be corrected, the magnetic ball 208 is demagnetized by powering off. At this time, the magnetic ball 208 automatically returns to the surface of the electromagnetic plate 209 under the action of the tension spring 207, and under the action of gravity, the top cover 203 rotates to the bottom, thereby realizing the automatic correction of the three-dimensional graph. After completing the automatic correction work, the magnetic ball 208 is powered on again to conduct magnetism and automatically returns to the middle of the top cover 203 and the ball switch 201, forming a control ball and computer. The 3D software in the apparatus forms a connection and controls the rotation of the 3D graph. When the spherical switch 201 and the top cover 203 form a sphere to control the 3D graph, the magnetic ball 208 generates magnetic attraction to the extrusion block 212 inside the peripheral limit ring 202, so that the extrusion block 212 can fix the surface of the top cover 203 and the spherical switch 201 by friction. After adjusting the position of the 3D graph, the spherical switch 201 is released. At this time, the extrusion block 212 fixes the spherical switch 201 and the top cover 203, so that the spherical switch 201 and the top cover 203 will not roll at will, thereby achieving the angle fixation of the 3D graph.

[0046] The top cover 203 is limited in rolling by the limit ring 202. When the ball switch 201 and the top cover 203 form a sphere, the ball switch 201 is rotated to a fixed position and the hand is released. The squeezing block 212 inside the limit ring 202 will be squeezed inward under the action of magnetic attraction, thereby pressurizing the surface of the ball switch 201 and the top cover 203, and then fixing the top cover 203 and the ball switch 201, so that the user can view the three-dimensional image conveniently. When it is necessary, it will automatically return to the front. At this time, the magnetic ball 208 is powered off and demagnetized, and automatically returns to the top of the electromagnetic plate 209 under the action of the tension spring 207. At this time, the top cover 203 will also lose the limiting effect of the extrusion block 212, and the spherical switch 201 will automatically rotate to the bottom under the gravity of the magnetic ball 208, so that the three-dimensional graph is returned to the center, realizing automatic fixing of the angle of the three-dimensional graph and automatically realizing the return of the three-dimensional graph, which solves the problem that the angle of the three-dimensional graph cannot be well controlled by the touch panel in the prior art.

[0047] Embodiment 2 further optimizes the touch panel bracket provided in Embodiment 1. Specifically, Figure 2-Figure 5 As shown, four clamping blocks 211 are provided at equal angles on the inner side of the circumference of the limit ring 202, and an extrusion block 212 is slidably installed inside the clamping block 211. The extrusion block 212 is located on the circumference of the middle part of the top cover 203. When the magnetic ball 208 is located in the middle of the top cover 203 and the ball switch 201, the center of gravity of the extrusion block 212 and the magnetic ball 208 are on the same horizontal plane, and the magnetic ball 208 generates an attraction force on the extrusion block 212. The bottom of the spring piece 103 is located on both sides of the control component 2. A housing 107 is rotatably installed at the bottom of the inner cavity of the housing 107. A guide threaded cylinder 214 is fixedly installed on the top of the gear 213. The internal thread sleeve of the guide threaded cylinder 214 is provided with a lifting rod 215. The top of the spring piece 103 A pair of guide grooves 110 are symmetrically provided on the top cover 203, and the lifting rod 215 is vertically slidably connected to the inside of the lifting rod 215. The bottom circumferential array of the ball switch 201 is provided with a card slot 206. When the ball switch 201 moves downward, the card slot 206 and the gears 213 on both sides are meshed with each other. When the top cover 203 rotates, the traction gear 213 rotates synchronously, and the lifting rod 215 moves vertically up and down. The middle of the PCB board 101 and the touch panel 102 are provided with a docking hole 108. The top cover 203 moves up to the top and extends out from the docking hole 108 in the middle of the PCB board 101 and the touch panel 102. The top cover 203 moves down to the bottom and is located inside the ball switch 201, and the top of the top cover 203 is lower than the top of the docking hole 108.

[0048] The ball switch 201 is moved downward by pressing the top cover 203 and meshed with the gear 213 at the bottom. At this time, the ball switch 201 can be pulled by rotating the top cover 203 to rotate the gear 213 synchronously, thereby controlling the lifting rod 215 to move upward, so that the interior of the touch panel can be easily inspected and maintained. Here, the PCB board 101 is attached to the top of the support frame 1 by magnetic attraction and is movably hinged inside the computer.

[0049] In order to solve the problem that the rotation and orientation of the three-dimensional graph cannot be controlled by the touch panel when performing three-dimensional design, the present application generates a repulsive reaction by providing a control component 2 to energize the magnetic ball 208 and the electromagnetic plate 209. At this time, the magnetic ball 208 moves up and causes the top cover 203 to move upward to lift and form a round sphere with the spherical switch 201. At this time, the spherical switch 201 is rotated to rotate the sphere, so that the three-dimensional graph can be rotated to different angles. At the same time, gears 213 are provided on both sides of the spherical switch 201. The top cover 203 is pressed downward, and the card slot 206 is meshed with the gear 213. At this time, the top cover 203 can drive the gear 213 to rotate to move the lifting rod 215 up and down, so that the lifting and lowering of the touch panel 102 can be controlled, so that the lower components of the PCB board 101 can be easily inspected and maintained, and the angle rotation of the three-dimensional graph can be controlled by the touch panel, and the lifting of the PCB board 101 and the touch panel 102 can be controlled in different states, so as to facilitate inspection and maintenance.

[0050] The use process of the touch panel bracket, touch panel and electronic input device provided by the present invention is as follows:

[0051] By pressing any point on the surface of the touch panel 102, pressure is generated on the PCB board 101 at the bottom, and the pressure is transmitted to the reinforcing plate 104, and pressure is generated on the limit ring 202 in the middle of the spring 103 through the PCB board 101, so that the ball switch 201 moves downward and contacts and conducts with the contact base 109 at the bottom. After the conduction is completed, the reset spring 106 at the top of the guide bolt 105 supports the spring 103 when it is loosened, and resets the spring 103;

[0052] The magnetic ball 208 is powered on to conduct magnetism and the electromagnetic plate 209 produces a repulsive reaction, and the top cover 203 extends from the top of the spherical switch 201 to form a sphere. At this time, the rotation of the three-dimensional graph can be controlled by rotating the spherical switch 201 and the top cover 203. At the same time, when the graph needs to be corrected, the magnetic ball 208 is powered off and demagnetized. At this time, the magnetic ball 208 is automatically reset to the surface of the electromagnetic plate 209 under the action of the tension spring 207, and the top cover 203 is rotated to the bottom under the action of gravity, thereby realizing automatic correction of the three-dimensional graph. After completing the automatic correction work, the magnetic ball 208 is powered on again to conduct magnetism and automatically returns to the top cover 203 and the spherical switch 201. In the middle, a control ball is formed to connect with the three-dimensional software in the computer and control the rotation of the three-dimensional graph. When the spherical switch 201 and the top cover 203 form a sphere to control the three-dimensional graph, the magnetic ball 208 generates magnetic attraction to the extrusion block 212 inside the surrounding limit ring 202, so that the extrusion block 212 can fix the surface of the top cover 203 and the spherical switch 201 by friction. After adjusting the position of the three-dimensional graph, release the spherical switch 201. At this time, the extrusion block 212 fixes the spherical switch 201 and the top cover 203, so that the spherical switch 201 and the top cover 203 will not roll at will, thereby achieving the angle fixation of the three-dimensional graph.
