Description

Technical Field

[0001] This invention relates to the technical field of terminal devices, specifically to a push-button rotary switch and a terminal device using such a push-button rotary switch. Background Technology

[0002] Most existing terminal devices are equipped with microphones, cameras, and communication antennas. Since microphones and cameras can capture people's voices and images, there are security risks related to privacy leaks, while communication antennas can transmit personal privacy data. To protect personal privacy, some existing terminal devices allow users to manually turn off the microphone, camera, or communication antenna. For example, utility model patent CN222214026U discloses a terminal device with a safety switch circuit. This device can disconnect the microphone, camera, and communication antenna, thereby preventing the leakage of personal information in scenarios requiring confidentiality.

[0003] However, while existing safety switch circuits use rotary switches, they are relatively bulky, and because the knob is not a push-button type, it cannot be concealed within the terminal device's housing. If the knob is exposed, users are prone to accidentally touching it, causing it to turn and unintentionally turn on or off controlled devices such as microphones, cameras, and communication antennas. If the knob is concealed within the housing, users often find it difficult to turn it, making it inconvenient to switch the status of controlled devices. Utility Model Content

[0004] The primary objective of this invention is to provide a push-button rotary switch that is convenient for users and prevents accidental touches.

[0005] The second objective of this invention is to provide a terminal device having the aforementioned push-button rotary switch.

[0006] To achieve the first objective of this invention, the push-button rotary switch provided by this invention includes a rotary switch assembly with a base. The rotary switch assembly includes multiple switch modules, each switch module having a first conductive terminal, a second conductive terminal, and a third conductive terminal. A rotating shaft is disposed within the base, and the rotating shaft can rotate within the base. When the rotating shaft is in a first angle region, the first conductive terminal is electrically connected to the second conductive terminal; when the rotating shaft is in a second angle region, the first conductive terminal is electrically connected to the third conductive terminal. The first end of the rotating shaft extends out of the base. In addition, a pressing assembly is provided at the first end of the rotating shaft. The pressing assembly includes a sleeve extending from the first end of the rotating shaft. A pressing knob is installed inside the sleeve. The pressing knob has a groove with a first limiting position and a second limiting position. The first limiting position and the second limiting position are arranged along the axial direction of the rotating shaft. The first end of the pull rod slides in the groove and can move between the first limiting position and the second limiting position. The second end of the pull rod is fixed on the rotating shaft. An elastic reset member is also installed inside the sleeve. The two ends of the elastic reset member abut against the bottom wall of the sleeve and the pressing knob, respectively. The end of the pressing knob away from the rotating shaft is exposed outside the sleeve.

[0007] As can be seen from the above scheme, a pressing component is provided at the first end of the rotating shaft. The pressing component includes a pressing knob, which can extend or retract along the axial direction of the rotating shaft. Thus, when the pressing knob needs to be pressed, the user can pull it out and turn it. When the pressing knob does not need to be turned, it can be retracted into the housing, thereby preventing the user from accidentally touching the pressing knob and causing the controlled device to be incorrectly turned on or off.

[0008] A preferred embodiment is that the slot is provided with a ring-shaped channel, with a first limiting position located at the end of the channel near the rotating shaft and a second limiting position located at the end of the channel away from the rotating shaft.

[0009] Therefore, the first and second limiting positions are set in the slot along the axial direction of the rotating shaft, and the pull rod enables the rotating shaft to move axially, making it convenient for the user to extend or retract the pull rod.

[0010] A preferred embodiment is that the bottom of the channel has a stepped surface or a guide ramp. This allows the first end of the pull rod to slide smoothly within the channel, enabling the pull rod to move smoothly between the first and second limiting positions.

[0011] A further option is to provide a grip at one end of the pressing knob that is exposed on the sleeve, with the grip extending radially along the pressing knob.

[0012] Therefore, when the pressing knob extends out of the terminal device's housing, the user can easily rotate the pressing knob by holding it.

[0013] A further solution is to provide a pull rod insertion hole on the rotating shaft, into which the second end of the pull rod is inserted.

[0014] Therefore, the second end of the pull rod is inserted into the pull rod insertion hole of the rotating shaft, so that the axial movement of the pressing knob can drive the axial movement of the pull rod.

[0015] A further embodiment is that a first limiting groove is provided at the first end of the rotating shaft exposed on the base, and a first retaining ring is fastened in the first limiting groove; and / or a second limiting groove is provided at the second end of the rotating shaft exposed on the base, and a second retaining ring is fastened in the second limiting groove.

[0016] Therefore, by setting limiting grooves and retaining rings at both ends of the rotating shaft, the axial direction of the rotating shaft is limited by the retaining rings, preventing the rotating shaft from moving axially relative to the base, and ensuring that the rotating shaft can correctly abut against the corresponding conductive terminal.

[0017] A further improvement is that at least one drive block is provided on the peripheral wall of the pressing knob, and the drive block extends outward from the peripheral wall of the pressing knob; the peripheral wall of the sleeve is provided with a groove that mates with the drive block.

[0018] Therefore, when the button is pressed and rotated, the drive block can drive the sleeve to rotate. Since the sleeve is fixed at one end of the rotating shaft, the present invention can ensure the synchronous rotation of the button and the rotating shaft.

[0019] A further approach is to have two or more drive blocks, with multiple drive blocks evenly arranged along the circumference of the pressing knob.

[0020] As can be seen, multiple drive blocks drive the sleeve to rotate, making the force on the multiple drive blocks more even and avoiding damage to the drive blocks.

[0021] A further alternative is that the outer surface of the rotating shaft has a protrusion that can abut against the first conductive terminal.

[0022] Therefore, by having the protrusion on the outer surface of the rotating shaft abut against the first conductive terminal, the position of the first conductive terminal is changed, thereby realizing the electrical connection between the first conductive terminal and the second and third conductive terminals, and realizing the on / off control of the controlled device.

[0023] To achieve the second objective of this invention, the terminal device provided by this invention includes a housing, a display screen on the housing, and multiple controlled devices; it also includes the aforementioned push-button rotary switch, which is electrically connected to the multiple controlled devices and is pressed within the housing.

[0053] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0054] The terminal device of this invention can be a smartphone, tablet computer, etc. The terminal device has a housing with a display screen and multiple controllable devices, including a microphone, speaker, camera, communication antenna, etc. The camera may include a front-facing camera and a rear-facing camera. Furthermore, the terminal device also includes a push-button rotary switch, which is located inside the housing. The push-button knob of the switch can be hidden within the housing to prevent accidental activation or deactivation of the controllable devices by the user.

[0055] First embodiment:

[0056] See Figure 1 and Figure 2 The push-button rotary switch 100 of this embodiment includes a rotary switch assembly 110 and a push-button assembly, with the push-button assembly disposed at one end of the rotary switch assembly 110. The rotary switch assembly 110 has an elongated base 111, within which a rotating shaft 130 is disposed. The rotating shaft 130 is supported within the base 111 and can rotate within the base 111. See also... Figure 4 The base 111 has circular through holes 116 and 117 at both ends, and the two ends of the rotating shaft 130 pass through the through holes 116 and 117 and extend to the two ends of the base 111.

[0057] To restrict the axial movement of the rotating shaft 130, retaining rings are provided at both ends of the rotating shaft 130. For details, see... Figure 6 and Figure 7 A first limiting groove 135 is provided at the first end of the rotating shaft 130, located at the first end of the rotating shaft 130 exposed on the base 111. A first retaining ring 137 can be inserted into the first limiting groove 135. A second limiting groove 136 is provided at the second end of the rotating shaft 130, located at the second end of the rotating shaft 130 exposed on the base 111. A second retaining ring 138 can be inserted into the second limiting groove 136. Through the limiting action of the first retaining ring 137 and the second retaining ring 138, the rotating shaft 130 cannot move axially.

[0058] In addition, the rotary switch assembly 110 is provided with multiple switch modules, each with three conductive terminals. The following description uses one of these switch modules as an example. (See...) Figures 3 to 5 One of the open-mold assembly's corresponding conductive terminals includes a first conductive terminal 121, a second conductive terminal 122, and a third conductive terminal 123. The first conductive terminal 121 has a first spring arm 125 and a second spring arm 126 that are parallel to each other, connected by a connecting arm, and is connected to the controller of the terminal device. The second conductive terminal 122 is located near the first spring arm 125, and the third conductive terminal 123 is located near the second spring arm 126. Furthermore, the second conductive terminal 122 is connected to a controlled device, such as a camera, microphone, speaker, or communication antenna, while the third conductive terminal 123 is connected to an equivalent load, such as an equivalent resistance or equivalent load, the impedance of which is equal to the impedance of the controlled device connected to the second conductive terminal 122.

[0059] The base 111 is provided with a first conductive terminal mounting position 113, a second conductive terminal mounting position 114 and a third conductive terminal mounting position 115. The first conductive terminal 121 is mounted on the first conductive terminal mounting position 113, the second conductive terminal 122 is mounted on the second conductive terminal mounting position 114 and the third conductive terminal 123 is mounted on the third conductive terminal mounting position 115.

[0060] A protrusion 131 is formed on the outer surface of the rotating shaft 130. The protrusion 131 does not cover the entire outer surface of the rotating shaft 130, but is formed on a portion of the outer surface of the rotating shaft 130. Figure 4 As can be seen, the area on the outer surface of the rotating shaft 130 where the protrusion 131 is not provided forms a recessed area 132. In addition, the central angle of the protrusion 131 relative to the axis of the rotating shaft 130 is less than or equal to 180°.

[0061] In this embodiment, the first spring arm 125 of the first conductive terminal 121 is closer to the axis of the rotation shaft 130 than the second conductive terminal 122, and the second spring arm 126 of the first conductive terminal 121 is closer to the axis of the rotation shaft 130 than the third conductive terminal 123. Furthermore, since the rotation shaft 130 is provided with a protrusion 131, when the protrusion 131 abuts against the first spring arm 125, the first spring arm 125 shifts towards the second conductive terminal 122, thus achieving electrical connection between the first spring arm 125 and the second conductive terminal 122. At this time, the second spring arm 126 is not abutted by the protrusion 131, but faces the recessed area 132. Therefore, the second spring arm 126 will not shift towards the third conductive terminal 123, creating a gap between the second spring arm 126 and the third conductive terminal 123. Therefore, the second spring arm 126 and the third conductive terminal 123 will not be electrically connected. In this state, the rotation shaft 130 is located in the first angle region, enabling electrical connection between the controller and the controlled device.

[0062] When the rotating shaft 130 rotates, the protrusion 131 will not abut against the first spring arm 125, and the first spring arm 125 will not shift towards the second conductive terminal 122, so that the first spring arm 125 and the second conductive terminal 122 will not be electrically connected. At this time, the second spring arm 126 is abutted by the protrusion 131, causing the second spring arm 126 to shift towards the third conductive terminal 123, so that the second spring arm 126 and the third conductive terminal 123 are electrically connected. In this state, the rotating shaft 130 is located in the second angle region, realizing the electrical connection between the controller and the equivalent load.

[0063] Because the rotary switch assembly contains multiple switch modules, these modules can be divided into groups. For example, the first group might contain eight switch modules, the second three, the third two, and the fourth nine. Each group corresponds to a different type of controlled device; for instance, the first group might correspond to a camera, the second to a microphone, etc. Figure 4 and Figure 8 As can be seen, the positions of the protrusions 131 arranged on the rotating shaft 130 are different for different groups of switch modules, so that when the rotating shaft 130 rotates to different positions, the on / off control of the controlled devices of different groups can be realized.

[0064] See Figures 15 to 19 At different positions on the rotating shaft 130, the protrusions 131 corresponding to each group of switch modules are at different circumferential positions on the rotating shaft 130, and correspondingly, the recessed areas 132 corresponding to each group of switch modules are also at different circumferential positions on the rotating shaft 130.

[0065] When the user twists or presses the component, it causes the rotating shaft 130 to rotate. Therefore, the rotating shaft 130 can be positioned at different gear positions. To ensure that the rotating shaft 130 is accurately positioned at the corresponding gear position, positioning components are provided at both ends of the rotating shaft. See also... Figure 8 and Figure 9 A positioning ring 144 is provided at the first end of the rotating shaft 130. The positioning ring 144 has multiple positioning holes 145 arranged circumferentially, into which a first ball bearing 146 can be inserted. A positioning ring 147 is provided at the second end of the rotating shaft 130. The positioning ring 147 has multiple positioning holes 148 arranged circumferentially, into which a second ball bearing 149 can be inserted. The first ball bearing 146 and the second ball bearing 149 can be mounted within the base 111.

[0066] The pressing component is located at the first end of the rotating shaft 130, see [link / reference] Figures 10 to 13 A sleeve 140 is provided at the first end of the rotating shaft 130. In this embodiment, the sleeve 140 extends from the first end of the rotating shaft 130, meaning that the sleeve 140 and the rotating shaft 130 are integrally formed. One end of the sleeve 140 is open, forming a mounting cavity 141 inside the sleeve 140, and the pressing knob 150 is installed in the mounting cavity 141. The pressing knob 150 includes a main body 151, and a gripping part 155 is provided at the end of the main body 151 away from the rotating shaft 130. The gripping part 155 is exposed outside the sleeve 140 and extends radially along the pressing knob 150, and the maximum radial dimension of the gripping part 155 is greater than the radial dimension of the main body 151.

[0067] Two drive blocks 157 are provided on the peripheral wall of the main body 151 of the pressing knob 150. Each drive block 157 extends outward from the peripheral wall of the pressing knob 150. Two grooves 142 are provided on the peripheral wall of the sleeve 140. The two drive blocks 157 are evenly arranged along the circumference of the pressing knob, that is, symmetrically arranged. Each drive block 157 is inserted into a groove 142. When the pressing knob 150 is rotated, the sleeve 140 is driven to rotate through the cooperation of the drive blocks 157 and the grooves 142, which in turn drives the rotating shaft 130 to rotate.

[0068] A slot 152 is provided on the pressing knob 150, and a ring-shaped channel 153 is formed in the slot 152. A limit block 154 is provided in the channel 153. By limiting the channel 153, a first limit position 161 and a second limit position 162 are formed in the channel 153. The first limit position 161 and the second limit position 162 are arranged along the axial direction of the rotation shaft 130. Specifically, the first limit position 161 is located at the end of the channel 153 closer to the rotation shaft 130, and the second limit position 162 is located at the end of the channel 153 away from the rotation shaft 130.

[0069] The pressing assembly also includes a pull rod 165. The first end 166 of the pull rod 165 slides within the slot 152 and can move between the first limiting position 161 and the second limiting position 162. The second end 167 of the pull rod 165 is fixed to the rotating shaft 130. Specifically, the rotating shaft 130 is provided with a pull rod insertion hole 143, into which the second end 167 of the pull rod 165 is inserted. Furthermore, the bottom of the channel 153 is provided with a stepped surface or a guide ramp. When the first end 166 of the pull rod 165 slides within the channel 153, the stepped surface or guide ramp allows for smoother movement of the first end 166.

[0070] In addition, the sleeve 140 is equipped with an elastic reset element. In this embodiment, the elastic reset element is a spring 168, with both ends of the spring 168 abutting against the bottom wall of the sleeve 140 and the pressing knob 150, respectively. See also Figure 14 A spring mounting groove 158 is provided on the pressing knob 150, and the spring 168 is installed in the spring mounting groove 158.

[0071] In the initial state, the first end 166 of the pull rod 165 is engaged at the first limiting position 161. When the pressing knob 150 is pressed, the pressing knob 150 moves along the axial direction of the rotating shaft 130 towards the rotating shaft 130. At this time, the first end 166 of the pull rod 165 slides along the groove 153 away from the rotating shaft 130 and slides to the second limiting position 162. When the user releases the pressing knob 150, under the elastic restoring force of the spring 168, the pressing knob 150 moves along the axial direction of the rotating shaft 130 away from the rotating shaft 130, thereby causing the first end 166 of the pull rod 165 to engage at the second limiting position 162. At this time, the pressing knob 150 is in a position close to the rotating shaft 130. When the push-button rotary switch 100 is installed in the housing of the terminal device, with the first end 166 of the lever 165 engaged with the second limit position 162, the push-button knob 150 can be completely hidden inside the housing of the terminal device, preventing the user from accidentally touching the push-button knob 150 and causing it to rotate.

[0072] When the user needs to turn the pressing knob 150, pressing the pressing knob 150 again will move the first end 166 of the lever 165 from the second limit position 162 to the first limit position 161. At this time, the pressing knob 150 is in a position away from the rotating shaft 130, and the grip part 155 of the pressing knob 150 will be exposed outside the housing of the terminal device, allowing the user to easily turn the pressing knob 150.

[0073] In addition, two limiting structures are provided on the base. When the rotating shaft 130 rotates to the two extreme positions, the limiting structure restricts the rotating shaft 130 from continuing to rotate.

[0074] Second embodiment:

[0075] See Figure 20 The push-button rotary switch 200 of this embodiment includes a rotary switch assembly 210 and a push-button assembly 250, with the push-button assembly 250 disposed at one end of the rotary switch assembly 210. See also Figure 21 The rotary switch assembly 210 has an elongated base 211, within which a rotating shaft 240 is disposed. The rotating shaft 240 is supported within the base 211 and can rotate within the base 211. The pressing assembly 250 has a sleeve disposed at the first end of the rotating shaft 240 and a pressing knob. The structure of the pressing assembly 250 is the same as that of the pressing assembly in the first embodiment, and will not be described again.

[0076] See Figures 22 to 24 Multiple switch modules are mounted on the base 211. Each switch module has three conductive terminals. Taking one switch module as an example, it has a first conductive terminal 216, a second conductive terminal 217, and a third conductive terminal 218. The first conductive terminal 216 is used for electrical connection with the controller of the terminal device, the second conductive terminal 217 is used for electrical connection with the controlled device, and the third conductive terminal 218 is used for electrical connection with the equivalent load. Figure 24 As can be seen, one end of the first conductive terminal 216 extends to the first side of the base 211, and one end of the second conductive terminal 217 and the third conductive terminal 218 extends to the second side of the base 211. The portions extending outside the base 211 facilitate soldering with wires. A cover plate 220 is provided on the base 211, and a bracket 221 is provided below the cover plate 220. The rotating shaft 240 is located below the cover plate 220.

[0077] See Figure 23 The rotating shaft 240 is provided with multiple conductive regions, including, for example, a first conductive coating region 241, a second conductive coating region 242, and a third conductive coating region 243, all of which are covered with a conductive coating. Specifically, the first conductive coating region 241 corresponds to the first conductive terminal 216 and is electrically connected to it; the second conductive coating region 242 corresponds to the second conductive terminal 217 and is electrically connected to it; and the third conductive coating region 243 corresponds to the third conductive terminal 218 and is electrically connected to it.

[0078] Furthermore, the first conductive coating region 241 is located between the second conductive coating region 242 and the third conductive coating region 243, and the first conductive coating region 241 is connected to the second conductive coating region 242, and the first conductive coating region 241 is also connected to the third conductive coating region 243. Moreover, the central angle of the first conductive coating region 241 relative to the axial direction of the rotation axis 240 is 360°. For different groups of switch modules, the central angles of the second conductive coating region 242 and the third conductive coating region 243 relative to the axial direction of the rotation axis 240 are different. Taking the first group of switch modules as an example, see [link to example]. Figure 28 and Figure 29 The central angle α of the second conductive coating region 242 relative to the axis of rotation 240 is a small angle, for example, 58°. The sum of the central angle β of the third conductive coating region 243 relative to the axis of rotation 240 and the central angle α of the second conductive coating region 242 relative to the axis of rotation 240 is close to 360°, for example, the central angle β is 300°. Correspondingly, the central angle of the second conductive coating region 242 of the second set of switch modules relative to the axial direction of the rotation shaft 240 can be 118°, and the central angle of the third conductive coating region 243 relative to the axial direction of the rotation shaft 240 is 240°; the central angle of the second conductive coating region 242 of the third set of switch modules relative to the axial direction of the rotation shaft 240 can be 178°, and the central angle of the third conductive coating region 243 relative to the axial direction of the rotation shaft 240 is 180°; the central angle of the second conductive coating region 242 of the fourth set of switch modules relative to the axial direction of the rotation shaft 240 can be 238°, and the central angle of the third conductive coating region 243 relative to the axial direction of the rotation shaft 240 is 120°.

[0079] See Figures 25 to 27 Three support rods 225, 226, and 227 are provided on the bracket 221. A first torsion spring 231 is sleeved on the support rod 225, and the two torsion arms of the first torsion spring 231 abut against the first conductive coating area 241 and the first conductive terminal 216, respectively, thereby achieving electrical connection between the first conductive coating area 241 and the first conductive terminal 216. Similarly, a second torsion spring 232 is sleeved on the support rod 226, and the two torsion arms of the second torsion spring 232 abut against the second conductive coating area 242 and the second conductive terminal 217, respectively, thereby achieving electrical connection between the second conductive coating area 242 and the second conductive terminal 217. A third torsion spring 233 is sleeved on the support rod 227, and the two torsion arms of the third torsion spring 233 abut against the third conductive coating area 243 and the third conductive terminal 218, respectively, thereby achieving electrical connection between the third conductive coating area 243 and the third conductive terminal 218.

[0080] It should be noted that multiple switch modules can be divided into multiple groups, and each group of switch modules corresponds to a type of controlled device. Since different types of controlled devices are not turned on and off at the same time, the positions of the second conductive coating area 242 and the third conductive coating area 243 on the rotating shaft 240 corresponding to different switch modules are not the same.

[0081] This invention utilizes a pressing component at one end of a rotating shaft to conceal the pressing knob within the casing of the terminal device, preventing users from accidentally touching and incorrectly rotating the pressing knob.

[0082] Finally, it should be emphasized that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
