Description

Technical Field

[0001] This invention relates to the field of laptop computer testing technology, and more particularly to a rotation trigger angle detection device and method. Background Technology

[0002] With the rapid development of the consumer electronics industry, users want laptops to become thinner, lighter, more portable, and smarter. The requirements for the screen's on and off angles during the opening and closing process are becoming increasingly stringent. Currently, the control of laptop screen on and off is generally achieved through Hall sensors and magnets.

[0003] Currently, during the R&D phase, the rotation trigger angle achieved by the relative placement of the Hall sensor and the magnet can only be verified and confirmed through simulation. However, after the actual prototype is assembled, the actual rotation trigger angle of the prototype often does not match the simulation results. The simulation results during the R&D phase meet the customer's requirements for the rotation trigger angle, but the test results of the actual assembled prototype do not. This forces the R&D personnel to invest a lot of time to rematch the positional relationship between the magnet and the Hall sensor after the actual prototype is assembled in order to meet the customer's specifications for the rotation trigger angle, which greatly increases the cost of manpower and lengthens the project development cycle. Summary of the Invention

[0004] The purpose of this invention is to provide a rotation trigger angle detection device that can conveniently and quickly verify whether the rotation trigger angle achieved by the placement of the trigger and sensor meets the customer's required rotation trigger angle, effectively reducing labor costs and shortening the project development cycle, and improving the accuracy of the rotation trigger angle achieved by the placement of the trigger and sensor in actual installation.

[0005] Another objective of this invention is to provide a rotation trigger angle detection method that can conveniently and quickly verify whether the angle of the trigger triggering the sensor achieved by the placement of the trigger and the sensor meets the rotation trigger angle required by the customer. This effectively reduces labor costs and shortens the project development cycle, and improves the accuracy of the rotation trigger angle achieved by the placement of the trigger and the sensor in actual installation.

[0032] To illustrate the technical content, structural features, objectives, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] Please see Figures 1 to 6 This invention discloses a rotation trigger angle detection device, comprising: a support member 1, a rotating member 2, a rotation angle detection module 3, a trigger member 4, and a sensor module 5. The rotation angle detection module 3 includes a first bracket 31, a rotating bracket 32, and a second bracket 33. The first bracket 31 is connected to the support member 1. One end of the rotating bracket 32 ​​is rotatably connected to the first bracket 31, and the other end is slidably and adjustablely connected to the second bracket 33. The second bracket 33 is connected to the rotating member 2. The first bracket 31 is provided with an angle dial 311, which is used to view the angle of rotation of the rotating bracket 32 ​​relative to the first bracket 31. The trigger member 4 is detachably connected to the rotating member 2 and is used to emit a trigger signal. The sensor module 5 is detachably connected to the support member 1 and includes a sensor 51 and a conversion unit 52. The sensor 51 is electrically connected to the conversion unit 52. The sensor 51 is used to detect the trigger signal and send a drive signal to the conversion unit 52 according to the strength of the trigger signal. The conversion unit 52 is used to issue a prompt signal according to the received drive signal.

[0034] This invention includes a rotation angle detection module 3 to detect the rotation angle of the rotating component 2 relative to the support component 1 when the trigger 4 triggers the sensor module 5. The trigger 4 and the sensor module 5 are respectively positioned on the rotating component 2 and the support component 1 according to their actual installation positions. The rotation angle detection module 3 includes a first bracket 31, a rotating bracket 32, and a second bracket 33. The first bracket 31 is connected to the support component 1. One end of the rotating bracket 32 ​​is rotatably connected to the first bracket 31, and the other end is slidably and adjustablely connected to the second bracket 33. The second bracket 33 is connected to the rotating component 2. The first bracket 31 is provided with an angle dial 311. The sensor module 5 can detect the rotation angle of the rotating component 2 when it rotates closer to or away from the support component 1. When the device is far from the support 1, it detects the trigger signal emitted by the trigger 4 and issues a prompt signal based on the strength of the trigger signal. After the prompt signal is issued, the rotating component 2 stops rotating and the angle of rotation of the rotating bracket 32 ​​relative to the first bracket 31 is checked through the angle dial 311. This allows the device to obtain the rotation trigger angle of the trigger 4 triggering the sensor module 5. This facilitates a convenient and quick verification of whether the rotation trigger angle achieved by the placement of the trigger 4 and sensor 51 meets the customer's required rotation trigger angle. It effectively reduces labor costs and shortens the project development cycle, improving the accuracy of the rotation trigger angle achieved by the placement of the trigger 4 and sensor 51 in actual installation.

[0035] See Figure 1 and Figure 2 The sensor 51 is configured with a first preset value and a second preset value. The drive signal includes a first drive signal and a second drive signal. The prompt signal includes a first prompt signal and a second prompt signal that is different from the first prompt signal.

[0036] When the strength of the trigger signal is less than the first preset value, the sensor 51 sends a first drive signal to the conversion unit 52, and the conversion unit 52 issues a first prompt signal according to the first drive signal.

[0037] When the intensity of the trigger signal is greater than the second preset value, the sensor 51 sends a second drive signal to the conversion unit 52, and the conversion unit 52 issues a second prompt signal according to the second drive signal.

[0038] The above settings facilitate clear simulation and intuitive differentiation between the two processes of triggering sensor 51 when the device is turned on and when the device is turned off.

[0039] Specifically, in this embodiment, the support member 1 and the rotating member 2 are housings, used to simulate the D-shell and A-shell of a laptop computer, respectively, but not limited to this. Pushing the rotating member 2 to rotate away from or near the support member 1 simulates opening or closing the laptop screen. When the sensor module 5 detects that the intensity of the trigger signal of the trigger member 4 gradually decreases and is less than the first preset value, the laptop computer will control the laptop screen to turn on according to the first drive signal emitted by the sensor 51. When the sensor module 5 detects that the intensity of the trigger signal of the trigger member 4 gradually increases and is greater than the second preset value, the laptop computer will control the laptop screen to turn off according to the second drive signal emitted by the sensor 51. The conversion unit 52 will intuitively represent the two states of screen on and off through the first prompt signal and the second prompt signal, respectively, so that the rotation angle of the laptop screen relative to the laptop base can be tested when the sensor 51 drives the laptop screen to turn on and off under the trigger of the trigger member 4 during the research and development stage of the laptop computer.

[0040] See Figure 1 and Figure 2 The conversion unit 52 includes a signal converter 521, a first light-emitting element 522, and a second light-emitting element 523. The input terminal of the signal converter 521 is electrically connected to the sensor 51, and the output terminal of the signal converter 521 is electrically connected to the first light-emitting element 522 and the second light-emitting element 523. The first light-emitting element 522 emits a first color light to form a first prompt signal, and the second light-emitting element 523 emits a second color light to form a second prompt signal. The above-mentioned arrangement of light-emitting elements can convert the invisible signal changes of the sensor 51 into visible on / off states of the light-emitting elements, effectively improving the efficiency and operability of testing the rotation trigger angle during the research and development stage.

[0041] Specifically, in this embodiment, the conversion unit 52 further includes a circuit board 524 (PCB). The sensor 51, signal converter 521, first light-emitting element 522 and second light-emitting element 523 are mounted on the circuit board 524 by surface mount technology (SMT). The circuit board 524 is also provided with a switch 525 and a battery connector 527 connected to the battery 526, so that the components on the circuit board 524 can be powered by the battery 526 after the switch is turned on, but it is not limited to this.

[0042] Specifically, in this embodiment, the first light-emitting element 522 and the second light-emitting element 523 are LEDs that can emit different colors respectively, but are not limited thereto. In some embodiments, the conversion unit 52 can also emit different prompt signals by setting a display screen for displaying information or a player that emits sound.

[0043] Optionally, the trigger 4 is a magnetic element, the trigger signal is the magnetic field signal of the magnetic element, and the sensor 51 is a Hall sensor. However, it is not limited to this. In some embodiments, the trigger 4 can also be other transmitters capable of transmitting signals, and the sensor 51 is a receiver capable of receiving signals transmitted by the transmitter.

[0044] Specifically, in this embodiment, the circuit board 524 can be reused. Different Hall sensors are selected for different complete machines. By simply replacing the Hall sensor, the function of different Hall sensors can be simulated.

[0045] See Figures 1 to 6 The first bracket 31 includes a first connecting member 312 and a connecting shaft 313 that are fixedly connected. The first connecting member 312 is fixedly connected to the support member 1. The connecting shaft 313 is sleeved with an annular angle plate 311. The rotating bracket 32 ​​is in the shape of a long strip. One end of the rotating bracket 32 ​​near the first bracket 31 is provided with a sleeve hole 321 to be rotatably sleeved on the connecting shaft 313. When the rotating member 2 is pushed, the end of the rotating bracket 32 ​​connected to the second bracket 33 rotates around the connecting shaft 313. This is beneficial for testing and simulating different opening and closing angle standards of different whole machines. It is widely used and has strong applicability.

[0046] Specifically, in this embodiment, the first connector 312 is sheet-shaped and has a Z-shaped bent portion 3121 and a plurality of first through holes 3122. The first bracket 31 is detachably locked to the support member 1 by screws passing through the first through holes 3122. The connecting shaft 313 includes a cylindrical shaft portion 3131 and a sheet portion 3132. The bent portion 3121 is fixedly connected to the sheet portion 3132 so that the connecting shaft 313 and the first connector 312 are arranged side by side. The rotating bracket 32 ​​and the angle engraving disk 311 are sequentially sleeved on the shaft portion 3131 and fitted together. The rotating bracket 32 ​​can rotate relative to the shaft portion 3131. The angle engraving disk 311 is fixedly connected to the shaft portion 3131, but is not limited thereto.

[0047] Optionally, the rotating bracket 32 ​​is equipped with an angle pointer 320, and the angle dial 311 is provided with angle graduations 3111 along its circumference. The angle graduations 3111 include a zero-degree graduation 3110. When the rotating component 2 rotates parallel to the support component 1, the angle pointer 320 aligns with the zero-degree graduation 3110. The combination of the angle pointer 320 and the angle graduations 3111 facilitates the intuitive quantification of the rotation angle of the rotating component 2 during the opening and closing process.

[0048] Specifically, in this embodiment, the angle scale line 3111 is located on the side of the angle scale plate 311 away from the rotating bracket 32, and the angle pointer 320 is located on the side of the rotating bracket 32 ​​that is in contact with the angle scale plate 3111. The rotating member 2 is pushed to rotate the rotating bracket 32 ​​until the sensor 51 sends a drive signal to drive the conversion unit 52 to issue a prompt signal under the trigger of the trigger member 4. Then the rotating member 2 is stopped. At this time, the angle pointer 320 is aligned with a certain angle scale line 3111. The rotation trigger angle of the sensor 51 triggered by the trigger member 4 can be obtained by judging the angle between the aligned angle scale line 3111 and the zero-degree scale line 3110, but it is not limited to this.

[0049] See Figures 1 to 6 The rotating bracket 32 ​​is in the shape of a long strip. A channel 322 is provided at one end of the rotating bracket 32 ​​near the second bracket 33. The channel 322 extends along the extension direction of the rotating bracket 32. The second bracket 33 includes a second connector 331 and a locking fastener 332. The second connector 331 is fixedly connected to the rotating member 2. The second connector 331 includes an L-shaped sliding part 3311. The sliding part 3311 is provided with a connecting hole (not shown) corresponding to the channel 322. The locking fastener 332 passes through the channel 322 and the connecting hole to fix or loosen the second connector 331 to the rotating bracket 32. This is beneficial for simulating the distance between the trigger 4 and the sensor module 5 in different laptop computers. It is widely used and has strong applicability.

[0050] Specifically, in this embodiment, the second connector 331 is plate-shaped and has multiple second through holes 3312. The second bracket 33 is detachably locked to the rotating member 2 by screws passing through the second through holes 3312. The sliding part 3311 is arranged perpendicular to the second connector 331 at one end with a connecting hole. The locking member 332 includes a fixing screw 3321 and a fixing nut 3322. The fixing screw 3321 passes through the channel 322 and the connecting hole and is threadedly connected to the fixing nut 3322. When adjusting the distance between the rotating member 2 and the support member 1, the fixing screw 3321 is loosened, the rotating member 2 is pushed to drive the second connector 331 and the locking member 332 to slide along the channel 322, and then the fixing screw 3321 is tightened. However, this is not the only option.

[0051] Optionally, the side of the rotating bracket 32 ​​that contacts the second bracket 33 is provided with scale markings 323 along its extension direction.

[0052] Specifically, in this embodiment, a scale pointer 3313 is provided at the center of the connecting hole corresponding to the sliding part 3311, and a scale mark 323 is provided at the edge of the rotating bracket 32. The initial scale mark 323 is set to correspond to the center of the socket hole 321 of the rotating bracket 32, and extends to the position corresponding to the channel 322. By comparing a certain scale mark 323 aligned with the scale pointer 3313 with the initial scale mark, the axial distance between the first bracket 31 and the second bracket 33 can be determined, which facilitates the accurate adjustment of the moving distance of the second bracket 33 according to the scale mark 323.

[0053] See Figures 1 to 6 The sensor module 5 is attached to the side of the support 1 that contacts the first bracket 31 with adhesive; and / or, the trigger 4 is attached to the side of the rotating part 2 that contacts the second bracket 33 with adhesive, so as to facilitate the replacement of different sensor modules 5 and triggers 4 to verify the selection of sensor 51 and magnetic parts.

[0054] Please see Figures 1 to 7 This invention discloses a method for detecting a rotation trigger angle using the rotation trigger angle detection device described above, the method comprising:

[0055] 101. Adjust the distance between the rotating part 2 and the support part 1 by sliding the second bracket 33 according to the actual installation distance between the trigger 4 and the sensor 51;

[0056] Specifically, in this embodiment, before connecting the rotation angle detection module 3 to the rotating part 2 and the support part 1, the distance between the second bracket 33 and the first bracket 31 is adjusted by the locking fastener 332 so that after the rotating part 2 is connected to the support part 1 through the rotation angle detection module 3 and rotates to be parallel to each other, the distance between the trigger 4 on the rotating part 2 and the sensor 51 on the support part 1 matches the actual distance between the trigger 4 and the sensor 51 when they are installed on the entire laptop. However, this is not the only limitation. After adjustment, the rotation angle detection module 3 is locked to the rotating part 2 by the second bracket 33.

[0057] 102. Connect the trigger 4 to the rotating part 2 according to the position of the trigger 4 relative to the rotating shaft during actual installation;

[0058] Specifically, in this embodiment, the hinge in the actual laptop is equivalent to the connecting shaft 313 of the rotating bracket 32 ​​in the rotation angle detection module 3. The trigger 4 is attached to the rotating part 2 at the position relative to the connecting shaft 313, according to the actual installation position of the trigger 4 relative to the hinge. However, it is not limited to this.

[0059] 103. Connect the sensor module 5 to the support member 1 according to the position of the sensor 51 relative to the rotating shaft during actual installation;

[0060] Specifically, in this embodiment, the hinge in the actual laptop computer corresponds to the connecting shaft 313 of the rotating bracket 32 ​​in the rotation angle detection module 3. Referring to the actual mounting position of the sensor 51 relative to the hinge, the sensor module 5 is attached to the support 1 at a position relative to the connecting shaft 313, so that the sensor 51 is opposite the trigger 4 when the rotating component 2 and the support 1 are parallel, but this is not a limitation. After attaching the trigger 4 and the sensor module 5, the first bracket 31 is then locked onto the support 1 to secure the rotating component 2 and the support 1 together, and the switch on the circuit board 524 is turned on.

[0061] 104. Push the rotating component 2 to drive the rotating bracket 32 ​​to rotate until the conversion unit 52 issues a prompt signal;

[0062] 105. Observe the angle of rotation of the rotating bracket 32 ​​relative to the first bracket 31 through the angle dial 311 to obtain the rotation trigger angle.

[0063] Specifically, in this embodiment, the rotating member 2 is first rotated to a state parallel to the support member 1 to simulate the screen and base of the laptop computer being closed at 0 degrees. Then, the rotating member 2 is slowly pushed to rotate until the sensor 51 drives the first light-emitting element 522 to emit the first color light and then stops rotating. The rotation trigger angle when the screen is turned on is determined by the angle mark 3111 pointed to by the angle pointer 320 and the zero-degree mark 3110. Similarly, the opened rotating member 2 is rotated closer to the support member 1 to simulate the screen being turned off until the sensor 51 drives the second light-emitting element 523 to emit the second color light and then stops rotating. The rotation trigger angle when the screen is turned off is determined by the angle mark 311, but it is not limited to this.

[0064] In this application, the distance between the support 1 and the rotating component 2 is adjusted by the rotation angle detection module 3 to match the distance between the trigger 4 and the sensor 51 in the actual installation. Based on the actual installation positions of the trigger 4 and the sensor 51, the trigger 4 is installed on the rotating component 2, and the sensor module 5 is installed on the support 1. The rotating component 2 is rotated closer to or further away from the support 1 until the trigger 4 triggers the sensor module 5 to drive the conversion unit 52 to issue a prompt signal and then stops rotating. The angle of rotation of the rotating bracket 32 ​​relative to the first bracket 31 is viewed through the angle dial 311, thereby obtaining the rotation trigger angle of the trigger 4 triggering the sensor module 5. This facilitates convenient and rapid verification of whether the rotation trigger angle achieved by the placement of the trigger 4 and the sensor 51 meets the customer's required rotation trigger angle, effectively reducing labor costs and shortening the project development cycle, and improving the accuracy of the rotation trigger angle achieved by the placement of the trigger 4 and the sensor 51 in the actual installation.

[0065] The above-disclosed embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
