Description

Technical Field

[0001] This utility model belongs to the field of computer key technology, and in particular relates to a DC geared motor unlocking structure and a computer key. Background Technology

[0002] Regular inspections are required for equipment in power systems, such as high-voltage switchgear and substations. For high-risk equipment like high-voltage switchgear, unlocking must be performed in a predetermined sequence to ensure the safety of inspection personnel. The unlocking sequence is generally determined based on the inspector's experience; however, human experience is prone to error, and certain safety hazards still exist.

[0003] In the current high-voltage switchgear inspection process, the unlocking sequence is pre-set as a task ticket and sent to the computer key. Inspectors use the computer key to unlock the high-voltage switchgear according to the preset sequence on the task ticket. If the unlocking is not performed according to the preset sequence on the task ticket, the inspectors cannot open the high-voltage switchgear door using the computer key. However, current computer keys all rely on the engagement of electromagnets to lock and unlock, which consumes a lot of power and has a short battery life. Utility Model Content

[0046] This utility model embodiment includes: an unlocking assembly, which includes a motor, a transmission shaft, an unlocking rod, an unlocking shaft, and a guide shaft. The unlocking shaft and the guide shaft are located inside the unlocking rod. One end of the transmission shaft is fixed to the output end of the motor, and the other end is fixed to one end of the unlocking shaft. The other end of the unlocking shaft is an arc-shaped end. The rear end of the guide shaft is provided with an arc-shaped groove, and the arc-shaped end abuts against the arc-shaped groove. When the unlocking shaft rotates, the guide shaft moves inside the unlocking shaft, and the motor, the transmission shaft, and the unlocking shaft rotate synchronously; a code reading assembly, which includes a code reading base housing and a code reading induction coil. The code reading base housing is provided with a first through hole, through which the unlocking assembly passes. The code reading induction coil is fixed inside the code reading base housing; and a main control board, which is electrically connected to the motor and the code reading induction coil. According to the technical solution of this embodiment, the DC geared motor unlocking structure is inserted into the lock cylinder. The access control is verified by the code reading induction coil and the lock cylinder. When the DC geared motor unlocking structure passes the access control verification, the motor rotates forward and drives the unlocking shaft to rotate forward through the transmission shaft. The unlocking shaft drives the guide shaft to move forward and abut against the lock cylinder. The DC geared motor unlocking structure is rotated to complete the unlocking. After the unlocking is completed, the motor reverses, the unlocking component is reset, and the DC geared motor unlocking structure is removed from the lock cylinder to complete the unlocking process. The computer key is unlocked by the motor, which can reduce the required power consumption and extend the battery life.

[0047] Reference Figures 1 to 6 The DC geared motor unlocking structure 100 provided in this embodiment includes:

[0048] The unlocking assembly 110 includes a motor 11, a drive shaft 12, an unlocking rod 13, an unlocking shaft 14, and a guide shaft 15. The unlocking shaft 14 and the guide shaft 15 are located inside the unlocking rod 13. One end of the drive shaft 12 is fixed to the output end of the motor 11, and the other end is fixed to one end of the unlocking shaft 14. The other end of the unlocking shaft 14 is an arc-shaped end 141. The rear end of the guide shaft 15 is provided with an arc-shaped groove 151, and the arc-shaped end 141 abuts against the arc-shaped groove 151. When the unlocking shaft 14 rotates, the guide shaft 15 moves inside the unlocking shaft 14, and the motor 11, the drive shaft 12, and the unlocking shaft 14 rotate synchronously.

[0049] The code reading assembly 120 includes a code reading base housing 121 and a code reading induction coil 122. The code reading base housing 121 is provided with a first through hole, the unlocking assembly 110 passes through the first through hole, and the code reading induction coil 122 is fixed inside the code reading base housing 121.

[0050] The main control board 130 is electrically connected to the motor 11 and the code reading induction coil 122.

[0051] It should be noted that the middle part of the arc-shaped end 141 is hollowed out, and the protruding parts are the opposite sides. The opposite ends of the arc-shaped groove 151 are curved. When the unlocking component 110 is in the locked state, the arc-shaped end 141 is fitted into the arc-shaped groove 151, the middle part of the arc-shaped end 141 is fitted into the deepest part of the arc-shaped groove 151, and the protruding part of the arc-shaped end 141 is fitted into the curved ends of the arc-shaped groove 151. When the unlocking shaft 14 has finished rotating, that is, when the unlocking component 110 is in the unlocked state, the protruding part of the arc-shaped end 141 abuts against the curved ends of the arc-shaped groove 151. Since the protruding part of the arc-shaped end 141 cannot fit into the arc-shaped groove 151 at this time, there is a certain space between the arc-shaped end 141 and the arc-shaped groove 151, so that the guide shaft 15 moves forward under the drive of the unlocking shaft 14.

[0052] It should be noted that the front end of the unlocking rod 13 is provided with a lock groove, which can be engaged with the lock cylinder. The guide shaft 15 abuts against the lock cylinder. Therefore, when the unlocking shaft 14 drives the guide shaft 15 to move forward, the lock cylinder provides a reaction force to the guide shaft 15, thereby realizing the unlocking shaft 14 moving backward.

[0053] It should be noted that, in order to enable the unlocking shaft 14 to move horizontally, when the DC geared motor unlocking structure 100 is in the locked state, a certain amount of redundant space is provided at the engagement point between the unlocking shaft 14 and the transmission shaft 12 to avoid collision between the unlocking shaft 14 and the transmission shaft 12.

[0054] It should be noted that when the DC geared motor unlocking structure 100 is inserted into the lock cylinder, the unlocking rod 13 and the guide shaft 15 abut against the lock cylinder. The code reading coil 122 completes authorization verification with the lock cylinder. When verification is successful, the code reading coil 122 sends a first electrical signal to the main control board 130, which in turn sends a second electrical signal to the motor 11. The motor 11 drives the unlocking shaft 14 to rotate 90° clockwise via the transmission shaft 12. The unlocking shaft 14 then drives the guide shaft 15 to move forward inside the unlocking rod 13. The lock cylinder provides a reaction force to the guide shaft 15, causing the unlocking shaft 14 to move backward. Movement; the inspector rotates the DC geared motor unlocking structure 100. At this time, the unlocking rod 13 and the guide shaft 15 remain stationary, while the motor 11, transmission shaft 12, unlocking shaft 14, and code reading component 120 rotate synchronously to complete the unlocking. When the unlocking is complete, the main control board 130 sends an electrical signal to the motor 11, which reverses 90°, thereby driving the unlocking shaft 14 to reverse 90° synchronously. It then moves backward through the guide shaft 15, and the unlocking component 110 and code reading component 120 are reset. The inspector then removes the DC geared motor unlocking structure 100 from the lock cylinder, completing the entire unlocking process.

[0055] Additionally, in one embodiment, reference is made to Figure 3 and Figure 5 The unlocking component 110 further includes:

[0056] The motor retaining ring 19 and the motor 11 have a first limiting boss 111 on their outer side, and the motor retaining ring 19 abuts against the first limiting boss 111.

[0057] The fixed seat 20 has one end snapped between the motor pressure ring 19 and the motor 11. The fixed seat 20 has a second limiting boss 21 inside, which abuts against the drive shaft 12.

[0058] At least one limiting pin 22 is provided, the fixed base 20 is provided with at least one second through hole, the unlocking rod 13 is provided with at least one limiting groove 133, the limiting groove 133 is located inside the fixed base 20, the number of second through holes is greater than or equal to the number of limiting pins 22, the number of limiting grooves 133 is greater than or equal to the number of limiting pins 22, the limiting pin 22 passes through the second through hole, and the limiting pin 22 is fitted into the limiting groove 133.

[0059] It should be noted that the motor 11 is secured by the motor retaining ring 19, which is engaged with the first limiting boss 111 of the fixed base 20, and the motor retaining ring 19 and the fixed base 20 together fix the motor 11. The fifth boss of the fixed base 20 fixes the drive shaft 12 to the output end of the motor 11, preventing the drive shaft 12 from dislodging from the output end when the motor 11 rotates. The fixed base 20 and the unlocking rod 13 are fixed by the limiting pin 22, maintaining the relative position of the fixed base 20 and the unlocking rod 13.

[0060] Additionally, in one embodiment, reference is made to Figure 3 and Figure 5 The unlocking component 110 further includes:

[0061] The front end of the stop rod 16 and the unlocking rod 13 is provided with a third limiting boss 161. The stop rod 16 is located between the fixed seat 20 and the third limiting boss 161. The unlocking rod 13 is located inside the stop rod 16. The inside of the stop rod 16 is provided with at least one first steel ball groove 162.

[0062] At least one stop steel ball 17 is provided. The unlocking rod 13 is provided with a third through hole 131. The outer side of the unlocking shaft 14 is provided with a second steel ball groove 142. When the DC geared motor unlocking structure 100 is in the locked state, the stop steel ball 17 is located inside the communicating area formed by the third through hole 131 and the first steel ball groove 162. When the DC geared motor unlocking structure 100 is in the unlocked state, the stop steel ball 17 can be fitted into the second steel ball groove 142.

[0063] It should be noted that the motor 11 drives the guide shaft 15 to move forward through the transmission shaft 12 and the unlocking shaft 14. The guide shaft 15 abuts against the lock cylinder, and the lock cylinder provides a reaction force to the guide rod, thereby driving the unlocking shaft 14 to move backward, which in turn drives the second steel ball groove 142 to move backward, so that the stop steel ball 17 can be engaged in the second steel ball groove 142, thereby maintaining the unlocked state of the DC geared motor unlocking structure 100 and giving the inspector a certain amount of time to rotate the DC geared motor unlocking structure 100.

[0064] It should be noted that when the inspector rotates the DC geared motor unlocking structure 100 and completes the unlocking, the motor 11 reverses to drive the unlocking shaft 14 to rotate, thereby driving the guide rod to move backward, so that the arc end 141 is engaged in the arc groove 151, the unlocking shaft 14 moves forward and the stop steel ball 17 is pushed out of the second steel ball groove 142. When the unlocking shaft 14 and the guide shaft 15 are reset, the steel ball is located inside the connected area formed by the first through hole and the third through hole 131.

[0065] Additionally, in one embodiment, reference is made to Figure 3 and Figure 5 The unlocking component 110 further includes:

[0066] The reset spring 18 and the unlocking rod 13 are provided with a fourth limiting boss 132 inside, and the top of the unlocking shaft 14 is provided with a fifth limiting boss 143. The reset spring 18 is wrapped around the outside of the unlocking shaft 14 and is located between the fourth limiting boss 132 and the fifth limiting boss 143.

[0067] It should be noted that the reset spring 18 is located between the fourth limiting boss 132 and the fifth limiting boss 143. The motor 11 drives the unlocking shaft 14 to rotate forward through the transmission shaft 12. The unlocking shaft 14 moves backward, and the fifth limiting boss 143 moves backward. The distance between the fourth limiting boss 132 and the fifth limiting boss 143 is shortened, and the reset spring 18 is compressed to generate elastic force. When unlocking is completed, the motor drives the unlocking shaft 14 to rotate in reverse through the transmission shaft 12. The reset spring 18 generates elastic force to drive the unlocking shaft 14 to move forward, thereby realizing the reset of the unlocking shaft 14 and the guide shaft 15.

[0068] Additionally, in one embodiment, reference is made to Figure 4 and Figure 6 The code reading component 120 further includes:

[0069] At least one voltage detection electrode 123 is provided, and the code reader housing 121 is provided with at least one fourth through hole. The number of fourth through holes is greater than or equal to the number of voltage detection electrodes 123, and the voltage detection electrodes 123 are inserted through the fourth through holes.

A first Hall element 1241 and a second Hall element 1242 are provided on the surface of Hall plate 124. The included angle between the first Hall element 1241 and the second Hall element 1242 is 90°. The first Hall element 1241 and the second Hall element 1242 are electrically connected to the main control board 130 respectively.

[0071] It should be noted that when the main control board 130 sends an electrical signal to the motor 11, the motor 11 rotates. When the motor 11 rotates 90° clockwise, the first Hall element 1241 senses that the magnet has rotated to the same angle as it. The first Hall element 1241 sends an electrical signal to the main control board 130, and the main control board 130 sends an electrical signal to the motor 11 based on the electrical signal, and the motor 11 stops rotating.

[0072] It should be noted that when the motor 11 stops rotating, the inspector rotates the DC geared motor unlocking structure 100. The unlocking rod 13 and guide shaft 15, which are fitted into the lock cylinder, remain stationary. There is rotational motion between the magnet and the Hall plate 124. The second Hall element 1242 detects that the magnet has rotated to the same angle as it. The second Hall element 1242 sends an electrical signal to the main control board 130. The main control board 130 sends an electrical signal to the motor 11, and the motor 11 reverses.

[0073] Additionally, in one embodiment, reference is made to Figure 4 and Figure 6 The barcode reader housing 121 includes a barcode reader body 1211 and a barcode reader base plate 1212. The barcode reader base plate 1212 is snapped into the barcode reader body 1211, and the rear surface of the barcode reader base plate 1212 abuts against the fixing seat 20.

[0074] It should be noted that the code reader housing 121 has a split structure, which makes it easy to install the Hall plate 124 and the code reading induction coil 122 inside the code reader housing 121, and also makes it easy to install and replace.

[0075] In one embodiment, reference is made to Figure 7 This utility model embodiment also provides a computer key 200, which includes the DC geared motor unlocking structure 100 as described above.

[0093] It should be noted that when the inspector inserts the computer key 200 into the lock cylinder, the unlocking lever 13 engages with the lock cylinder, and the lock cylinder and computer key 200 complete the authorization verification. If the computer key 200 fails the authorization verification, the inspector cannot unlock the lock using the computer key 200. When the computer key 200 passes the authorization verification, the code reading induction coil 122 sends an electrical signal to the main control board 130, and the main control board 130 sends an electrical signal to the motor 11. The motor 11 drives the unlocking shaft 14 to rotate through the transmission shaft 12. The unlocking shaft 14 drives the guide shaft 15 to move forward through the arc-shaped end 141. The guide shaft 15 abuts against the lock cylinder, and the lock cylinder provides a reaction force to the guide shaft 15. The guide shaft 15 drives the unlocking shaft 14 to move backward, and the second ball groove 142 and the fifth limiting boss 143 move backward. The stop ball 17 engages with the second ball groove 142, thereby maintaining the unlocked state of the DC geared motor unlocking structure 100, and the return spring 18 is in a compressed state. When the first Hall element 1241 detects... Motor 11 rotates 90° forward, and the first Hall element 1241 sends an electrical signal to the main control board 130. The main control board 130 then sends an electrical signal to motor 11, causing motor 11 to stop. After motor 11 stops, the inspector turns the computer key 200, which drives the magnet fixed to the stop rod 16 to rotate. When the second Hall element 1242 detects that the rotation angle of the magnet is consistent with the second Hall element 1242, the second Hall element 1242 sends an electrical signal to the main control board 130. The main control board 130 then sends an electrical signal to motor 11, causing motor 11 to reverse. Motor 11 drives the unlocking shaft 14 to reverse via the transmission shaft 12, thereby moving the guide shaft 15 backward. Under the action of the reset spring 18, the unlocking shaft 14 moves forward, and the stop ball 17 is pushed out of the second ball groove 142. When the DC geared motor unlocking structure 100 resets, the stop ball 17 is located inside the connecting area between the first ball groove 162 and the third through hole 131, allowing the inspector to remove the computer key 200 from the lock cylinder.

[0094] It should be noted that during the use of the computer key 200, the inspector can control the display screen component 250 through the button 213. The display screen component 250 is used to display the task ticket, so that the inspector can view the task ticket and unlock the door according to the preset sequence.
