[0002] In electric locomotives, locomotive door locks are one of the important parts of the locomotive and an important part to ensure the safe operation of the locomotive. At present, the on-board door locks in the rail transit industry basically use mechanical locks. The current status of mechanical locks: 1. Whether the doors on the non-operating end are closed and whether the door locks are locked cannot be effectively monitored, and usually requires manual inspection. 2. During the driving of the locomotive, the driver or third party can open the door at will, causing personal accidents and posing major human safety hazards. 3. There is no monitoring of the driver or other parties using the door keys, and effective information traceability and information management cannot be achieved. 4. Locomotive keys are easy to confuse, and problems such as key loss, key mismatch, locomotive reconnection key failure, and key repair and replacement are often encountered. Utility Model Content

[0003] The utility model aims at the above technical problems existing in the mechanical locks of locomotives and provides an intelligent locomotive door lock. It improves on the existing mechanical lock structure, retains the mechanical lock function, and adopts motor drive technology to automatically realize accurate and fast unlocking action, and can display the switch status of the inner and outer door locks and the anti-lock status detection structure in real time, thereby improving the safety of the locomotive door lock.

[0004] The above-mentioned purpose of the utility model is achieved through the following technical solutions:

[0005] An intelligent motorcycle door lock comprises a lock body, a web and a lock core, wherein the lock body comprises an anti-locking connecting rod, the web comprises an upper outer web, a lower outer web, an upper inner web and a lower inner web, the upper outer web, the lower outer web and the upper inner web are all provided with handles, the lock core is also provided with the lock core, the upper inner web is provided with a knob for anti-locking, the anti-locking connecting rod is linked with the lock core and the knob; further comprising a driving device, the lock core comprises a pin body, a clutch body and a lock core sleeve ... The core sleeve has a cylindrical inner cavity, one end of the lock core sleeve is fixed to the side of the lower outer web facing the lock body, the pin body and the clutch body are arranged in the inner cavity of the lock core sleeve in sequence, the clutch body extends from the other end of the lock core sleeve and is connected to the square shaft one of the lock core; the power of the driving device is transmitted to the square shaft one of the lock core to drive the square shaft one of the lock core to rotate; the lock hole of the lock body crosses the pin body and the clutch body, and the key of the intelligent locomotive door lock can cross the pin body and the clutch body to realize the opening and closing actions.

[0006] The door lock used for locomotives is a double interlock, including an upper outer web, a lower outer web, an upper inner web and a lower inner web. The upper outer web, the lower outer web and the upper inner web are all equipped with handles, the lower outer web is equipped with a lock core, and the upper inner web is equipped with a knob. It also includes two linkage mechanisms, namely, a handle connecting rod connected to the handle and an anti-lock connecting rod connected to the latch. Step 1: After closing the locomotive door, the extended lock tongue hits into the lock box. Step 2: Turn the handle on the locomotive door, the latch extends out, and the secondary tightening of the locomotive door is completed. Step 3: Turn the knob on the upper inner web or use a key to turn the lock core to rotate the safety plate, and the anti-lock connecting rod moves up and inserts into the limit groove of the latch to complete the anti-lock. After anti-locking, the latch is locked and cannot be rotated anymore. Anti-locking can maximize the safety of the locomotive door. The lock core and the knob are respectively connected to a long square shaft with a square cross section. There are two safety plates (safety plate 1 and safety plate 2) on the anti-locking link, which are respectively connected to the square shafts of the lock core and the knob. The lock core or the knob is rotated outside the door to rotate the safety plate, thereby driving the anti-locking link to move up and down to achieve anti-locking. The two safety plates on the anti-locking link are linked, and one of the safety plates rotates to move the anti-locking link, and the other safety plate will passively rotate to rotate the other square shaft. In the utility model, the square shaft connected to the lock core in the prior art is called square shaft 1, and the square shaft connected to the knob is called square shaft 2. For example, the rotation of square shaft 1 drives the safety plate 1 at one end of the square shaft to rotate. Due to the linkage effect of the anti-locking link, the safety plate 2 at the second end of the square shaft will also rotate, causing the second square shaft to rotate.

[0007] The lock core of the utility model includes a pin body, a clutch body and a lock core sleeve. In the prior art, the pin body and the clutch body are integrated. The utility model is an intelligent locomotive door lock, which can realize automatic reverse locking. When automatically reverse locking, the driving device is electrically connected to the control system, the control system controls the driving device to act, and the driving device drives the square shaft one or the square shaft two to realize reverse locking. The power of the driving device is transmitted to the square shaft one of the lock core to drive the square shaft one of the lock core to rotate, which means: the driving device directly drives the square shaft one to rotate, or the driving device drives the square shaft two to rotate and link to rotate the square shaft one.

[0008] The separate structure of the pin body and the clutch body realizes the clutch function at the lock core. When the lock is automatically reversed, the driving device drives the square shaft to rotate, so that the clutch body rotates. The pin body and the clutch body are separate, and the pin body will not rotate, that is, the lock core has the "clutch" function. The pin body and the clutch body are located in the lock core sleeve, and the clutch body rotates in the lock core sleeve. The utility model preferably has a clamp installed on the end face of the lock core sleeve to prevent the clutch body from jumping out of the lock core sleeve.

[0009] When the driving device fails or there is a problem with the power supply, the door lock cannot be opened automatically. Therefore, the utility model also cleverly designs a clutch structure so that it still maintains the function of a mechanical lock, that is, a separate structure of the pin body and the clutch body is designed, and the keyhole crosses the pin body and the clutch body. The pin body and the clutch body are connected using a key, and the pin body and the clutch body can be rotated together, so that when the square shaft rotates, the lock core has the function of "closing".

[0010] Furthermore, the driving device is installed on one side of the upper inner belly plate close to the lock body, and the output end of the driving device is connected to the square shaft 2 of the knob. The power of the driving device is transmitted to the square shaft 1 of the lock core to drive the square shaft 1 of the lock core to rotate, which means that the driving device drives the square shaft 2 of the knob to rotate, so that the safety plate 2 at the end of the square shaft rotates to push the anti-lock connecting rod to move, thereby driving the square shaft 1 to be linked.

[0011] The upper inner web and the lower inner web of the locomotive door lock are located inside the door, that is, inside the locomotive. The utility model installs the driving device inside the door to reduce the impact of the external environment on the driving device, so that the driving device can withstand special environments of high and low temperatures.

[0012] Furthermore, the driving device includes a motor, a gearbox and a swivel with a square hole which are sequentially connected in transmission, the square shaft 2 passes through the square hole of the swivel, the shape and size of the cross section of the square shaft 2 are adapted to the square hole of the swivel, and the rotation of the swivel drives the square shaft 2 to rotate.

[0013] The rotating body with the square hole is the output end of the driving device, and the second square shaft is connected to the output end of the driving device, that is, the second square shaft is connected to the rotating body.

[0014] Furthermore, the swivel is installed on the gearbox, and the end of the square shaft 2 facing the gearbox is also fixed with a coaxial cylindrical section and a square section in sequence, the cross-sectional area of ​​the cylindrical section is smaller than the cross-sectional area of ​​the square shaft 2, and the square shaft 2 passes through the gearbox from the square hole of the swivel, and one end of the square section is connected to the knob, and the other end of the square shaft 2 is connected to the safety plate; a square hole matching the square section is opened at the end of the knob facing the inside; an elastic element is arranged between the knob and the gearbox; and the distance between the knob and the gearbox is greater than the length of the square shaft 2 in the gearbox.

[0015] The utility model designs a cylindrical section, the cross-sectional area of ​​which is smaller than that of the square shaft 2, and the distance between the knob and the gearbox is greater than the length of the square shaft 2 in the gearbox. The reason for such a setting is that when the rod (the square shaft 2, the cylindrical section and the square section as a whole) is pushed inward, the square shaft 2 escapes from the square hole of the swivel. At this time, the cylindrical section is located in the square hole of the swivel, and the cross-sectional area of ​​the cylindrical section is smaller than that of the square hole of the swivel. The cylindrical section can rotate freely in the square hole of the swivel. At this time, turning the knob can rotate the rod. An elastic element is arranged between the gearbox and the knob. When the rod is pushed inward, the elastic element is compressed. After the knob is released, the elastic element stretches, and the rod is reset. After the reset, the square shaft 2 returns to the square hole of the swivel.

[0016] The utility model is provided with a cylindrical section and a square section, so that the intelligent locomotive door lock has not only an automatic anti-locking function, but also a mechanical lock function. When the automatic anti-locking is performed, the motor-gearbox drives the swivel to rotate, and the swivel drives the square shaft 2 to rotate to achieve anti-locking. At this time, the square shaft 2 cooperates with the square hole of the swivel for transmission. At this time, the knob is manually turned. Due to the square cooperation between the square hole of the swivel and the square shaft 2, the square shaft 2 cannot be rotated. When the motor fails or the power supply has problems and the automatic anti-locking and unlocking functions cannot be achieved, the mechanical lock function of the utility model is used. The specific operation is: push the knob inward to the bottom, and the square shaft 2 is disengaged from the square hole of the swivel. At this time, the cylindrical section is located in the square hole of the swivel, and the outer diameter of the cylindrical section is smaller than the cross-sectional width of the square hole of the swivel. The square section cooperates with the square hole of the knob. When the knob is turned, the cylindrical section can rotate, and the square shaft 2 can rotate, so as to achieve the manual unlocking and unlocking functions. That is to say, the inner lock of the locomotive door has a clutch function. When the motor is running normally, it has the "clutch" function. When manually unlocking, push the knob inward. At this time, the knob is connected to the second square shaft to realize the "clutch" function.

[0017] Furthermore, the elastic element is a spring, and the spring is strung on the cylindrical segment.

[0018] Furthermore, a T-shaped hole is opened at the inner end of the knob, the wider end of the T-shaped hole is a circular hole, the narrower end of the T-shaped hole is the square hole, the outer diameter of the circular hole is larger than the outer diameter of the cylindrical section, and one end of the spring is fixed in the circular hole.

Therefore, the distance between the knob and the gearbox is greater than the length of the matching section.

[0020] Since the motor and the gearbox are installed in the upper inner web of the utility model, and there is a distance d between the knob and the gearbox, the upper inner web of the utility model is thicker than the upper inner web of the prior art.

[0021] Furthermore, the clutch body is engaged with the square shaft 1, and one end of the clutch body extending from the lock core sleeve is two protrusions, with a gap between the two protrusions, and the end of the square shaft 1 is engaged between the two protrusions.

[0022] Furthermore, a dust cover is installed on the outer side of the lower outer belly plate and at the installation position of the lock core. A sealing ring is arranged around the lock core. The sealing ring is in contact with the dust cover. The dust cover not only covers but also has a waterproof function.

[0023] Furthermore, it also includes a battery and a solar power generation device. The driving device, the battery and the solar power generation device are electrically connected in sequence, and the photovoltaic panel of the solar power generation device is installed on the outer side of the upper outer web or the lower outer web.

[0024] Furthermore, it also includes an emergency charging port, which is electrically connected to the battery. Because the working frequency of the lock is not high, the power of the solar-powered battery used in the utility model is sufficient for the use of the lock, but in order to avoid special circumstances, an emergency charging port is also provided, which can be connected to an external power supply to charge the battery.

[0025] Furthermore, sensors are installed on the lower outer web and the upper inner web, and the sensors sense external signals and provide a start signal to the drive device.

DETAILED DESCRIPTION

[0055] The embodiments of the present invention are described in detail below with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims. Example

[0056] From the analysis of the background technology, it can be seen that mechanical locks are inconvenient in use. For example, anti-locking requires manual operation, and before the locomotive is running, it is necessary to check whether the door lock is locked one by one, which is very cumbersome, with a large workload and low efficiency. In addition, since effective supervision cannot be carried out, no one can detect even if the door lock is opened, which poses a great safety hazard. Therefore, the present application designs an intelligent locomotive door lock that can achieve one-button anti-locking, greatly increasing work efficiency. And the detection mechanism is set to detect the real-time status of anti-locking in real time to avoid safety accidents. Most importantly, the locomotive door lock is not set on the lock body, but on the upper inner web 3 and the lower outer web 2, which can improve the structure of the existing mechanical lock and greatly reduce the cost. The specific structure is analyzed as follows:

[0057] An intelligent motorcycle door lock, comprising a lock body, a web, a lock core 6 and a drive device, wherein the lock body comprises an anti-locking connecting rod, such as Figure 1 As shown, the web comprises an upper outer web 1, a lower outer web 2, an upper inner web 3 and a lower inner web 4. The upper outer web 1, the lower outer web 2 and the upper inner web 3 are all provided with a handle 5. The lower outer web 2 is also provided with the lock core 6. The upper inner web 3 is provided with a knob 7 for reverse locking. The reverse locking connecting rod is linked with the lock core 6 and the knob 7. Figure 2 and Figure 3 As shown, the lock core 6 includes a pin body 6a, a clutch body 6b and a lock core sleeve 6c, the lock core sleeve 6c has a cylindrical inner cavity, one end of the lock core sleeve 6c is fixed to the side of the lower outer web 2 facing the lock body, the pin body 6a and the clutch body 6b are sequentially arranged in the inner cavity of the lock core sleeve 6c, and the clutch body 6b extends from the other end of the lock core sleeve 6c and is connected to the square shaft 8 of the lock core 6; Figure 4 and Figure 5 As shown, the driving device is installed on one side of the upper inner web 3 close to the lock body, and the output end of the driving device is connected to the square shaft 2 9 of the knob 7. The driving device drives the square shaft 2 9 of the knob 7 to rotate, so that the safety plate 2 at the end of the square shaft 2 9 rotates to push the anti-lock connecting rod to move, thereby driving the square shaft 1 8 to move in linkage; the lock hole of the lock body crosses the pin body 6a and the clutch body 6b, and the key of the intelligent locomotive door lock can cross the pin body 6a and the clutch body 6b to realize the opening and closing actions.

[0058] like Figure 6As shown, the driving device includes a motor 12, a gearbox 13 and a swivel 14 with a square hole which are sequentially connected in transmission. The square shaft 9 passes through the square hole of the swivel 14. The shape and size of the cross section of the square shaft 9 are adapted to the square hole of the swivel 14. The rotation of the swivel 14 drives the square shaft 9 to rotate.

[0059] The swivel 14 is installed on the gearbox 13, and the end of the square shaft 29 facing the gearbox 13 is also fixed with a coaxial cylindrical section 10 and a square section 11 in sequence. The cross-sectional area of ​​the cylindrical section 10 is smaller than that of the square shaft 29. The square shaft 29 passes through the gearbox 13 from the square hole of the swivel 14, and one end of the square section 11 is connected to the knob 7, and the other end of the square shaft 29 is connected to the safety plate; the end of the knob 7 facing the inside is provided with a square hole matching the square section 11; a spring 16 is arranged between the knob 7 and the gearbox 13, and the spring 16 is strung on the cylindrical section 10; the distance between the knob 7 and the gearbox 13 is greater than the length of the square shaft 29 in the gearbox 13.

[0060] Through the above design, the driving device drives the square shaft 2 9 to rotate so that the square shaft 1 8 can be linked to realize the automatic locking inside and outside the door. At the same time, through the improvement of the lock core 6 and the improvement of the square shaft 2 9, the door lock also has the function of a mechanical lock. The following is a further improvement of the structure.

[0061] like Fig. 9 As shown, the knob 7 has a T-shaped hole 15 at one end facing inward, the wider end of the T-shaped hole 15 is a circular hole, and the narrower end of the T-shaped hole 15 is the square hole. The outer diameter of the circular hole is larger than the outer diameter of the cylindrical section 10, and one end of the spring 16 is fixed in the circular hole.

[0062] like Figure 7 and Figure 8 As shown, the square shaft 2 9 includes a connecting section 9a and a matching section 9b, the connecting section 9a is connected to the safety plate, the matching section 9b matches the square hole of the swivel 14, the matching section 9b is located in the square hole of the swivel 14, the connecting section 9a is located outside the square hole of the swivel 14, the length of the matching section 9b is d, and the knob 7 is pushed inward, that is, in the direction of the lock body, by a distance d to separate the matching section of the square shaft 2 9 from the swivel 14. Therefore, the distance between the knob 7 and the gearbox 13 is greater than the length of the matching section 9b.

[0063] Since the motor 12 and the gearbox 13 are installed in the upper inner web 3 of the utility model, and there is a distance d between the knob 7 and the gearbox 13, Figure 4 As shown, the upper inner web 3 of the present invention is thicker than the upper inner web 3 of the prior art.

[0064] The clutch body 6b is engaged with the square shaft 8. Figure 2As shown, one end of the clutch body 6b extending from the lock core sleeve 6c is two protrusions, there is a gap between the two protrusions, and the end of the square shaft 8 is clamped between the two protrusions.

[0065] A dust cover is also installed on the outside of the lower outer web 2 and at the installation location of the lock core 6. A sealing ring is arranged around the lock core 6. The sealing ring is in contact with the dust cover. The dust cover not only covers but also has a waterproof function.

[0066] It also includes a battery and a solar power generation device. The driving device, the battery and the solar power generation device are electrically connected in sequence. The photovoltaic panel of the solar power generation device is installed on the outer side of the upper outer web 1 or the lower outer web 2.

[0067] The utility model also includes an emergency charging port, which is electrically connected to the battery. Because the working frequency of the lock is not high, the power of the solar-powered battery is sufficient for the use of the lock, but in order to avoid special circumstances, an emergency charging port is also provided, which can be connected to an external power supply to charge the battery.

[0068] Sensors are installed on the lower outer web 2 and the upper inner web 3. The sensors sense external signals and provide start signals to the drive device. External signals refer to swiping cards, remote controls, APPs, touch buttons, etc., which send signals to the sensors. The sensor signals are transmitted to the control system to activate the drive device.

[0069] The following is a description of the intelligent locomotive door lock anti-lock signal transmission structure.

[0079] Instructions for use:

[0080] When the automatic reverse locking is performed, the motor 12 drives the gearbox 13, and the gearbox 13 drives the swivel 14 therein to rotate and drive the square shaft 29 to rotate. The square shaft 29 drives the safety plate 2 to rotate and push the reverse locking link upward. The safety plate 1 at the other end of the reverse locking link rotates passively, driving the square shaft 18 to rotate, thereby rotating the clutch body 6b. The rotation of the clutch body 6b causes the transmission sleeve 18 on the clutch body 6b to rotate together, and the driving block 18b pushes the upper stop bar 22 to move the sliding block 21 upward. The contact 20 squeezes the sensor on the inner side of the lower outer web 2, sending a signal of reverse locking completion to the control system, and the "open" sign 27 at the lower end of the sliding block 21 withdraws from the gap. At this time, the "closed" sign is seen from the outer side of the lower outer web 2. The motor 12 is powered by a solar cell.

[0081] During the automatic anti-locking process, the pin body 6a does not rotate. When unlocking, the motor 12 rotates in the opposite direction, the square shaft 2 9 rotates in the opposite direction, the anti-locking link moves down, the square shaft 1 8 rotates in the opposite direction, the transmission sleeve 18 on the clutch body 6b rotates in the opposite direction, the driving block 1 18b pushes the lower stop bar 22 to move the sliding block 21 down, the contact 20 separates from the sensor, and sends a signal of unlocking completion to the control system, and the "open" identification plate 27 at the lower end of the sliding block 21 enters the gap. At this time, the "closed" identification plate can be seen from the outer shell of the lower outer web 2.

[0082] When the motor 12 or the gearbox 13 fails or the power supply has a problem, the intelligent locomotive door lock cannot be opened automatically, and the function of the mechanical lock is used at this time. When a person is on the inside, the knob 7 on the upper inner web 3 is used, and the knob 7 is pushed inward to the bottom, the spring 16 is squeezed, and the matching section of the square shaft 2 9 is separated from the swivel 14. At this time, the cylindrical section 10 is located in the square hole of the swivel 14. The knob 7 is rotated, and the square shaft 2 9 can be rotated. The rotation of the square shaft 2 9 drives the safety plate 2 to rotate, and the safety plate 2 pushes the anti-locking connecting rod to move down. The safety plate 1 is linked and passively rotated, and the square shaft 1 8 rotates to complete the unlocking. When a person is on the outside of the door, the key is inserted into the lock hole to unlock, and the key passes through the pin body 6a and the clutch body 6b, and the pin body 6a and the clutch body 6b are connected into one body.
