DETAILED DESCRIPTION

[0046] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0047] Figure 1 Fig. 1 shows a front view of the automatic power-off locking device according to an embodiment of the present application, wherein the automatic power-off locking device comprises a connecting plate 1, a triggering assembly and a locking assembly; the connecting plate 1 is used to be connected with an electric vehicle, and the triggering assembly and the locking assembly are installed on the connecting plate 1;

[0048] The triggering assembly comprises a first mounting plate 2, a second mounting plate 9, a connecting rod 14 and a roller 8; the first mounting plate 2 and the second mounting plate 9 are installed on the connecting plate 1; one end of the connecting rod 14 is used to be rotationally connected with a foot prop connecting plate 13, and the other end of the connecting rod 14 is rotationally connected with the roller 8; the roller 8 is installed between the first mounting plate 2 and the second mounting plate 9;

[0049] The lock assembly comprises a mounting seat and a third pressure sensor 15, the mounting seat is mounted on one end of the second mounting plate 9 away from the foot support connecting plate 13, the third pressure sensor 15 is mounted on the bottom of the mounting seat, the third pressure sensor 15 is electrically connected with the control center of the electric vehicle, the control center is installed on the electric vehicle, used for monitoring the running state and battery capacity of the electric vehicle and receiving the pressure value of the sensor feedback, the rider can also transmit the control signal to the control center wirelessly through the mobile terminal and the like;

[0050] The foot support connecting plate 13 is rotationally mounted on the connecting plate 1, when the foot support connecting plate 13 rotates, the pulley 8 rolls between the first mounting plate 2 and the second mounting plate 9, when the foot support connecting plate 13 is in the vertical state, the pulley 8 presses the third pressure sensor 15;

[0051] The third pressure sensor feeds back the collected first pressure value to the control center, when the first pressure value is equal to or greater than the first threshold value, the control center controls the electric vehicle to be powered off, when the first pressure value is equal to or greater than the second threshold value, the control center controls the electric vehicle to be locked.

[0052] In the embodiment, when the rider stops, the foot support is turned from the horizontal state to the vertical state, at this time, the foot support connecting plate 13 rotates clockwise by ninety degrees to the vertical state, the pulley 8 presses the third pressure sensor 15, and the third pressure sensor 15 feeds back the first pressure value to the control center. Figure 1In the shown position, in the process, the foot support connecting plate 13 drives the connecting rod 14 to push the roller 8 to move to the right, when the roller 8 moves to the rightmost side and contacts the third pressure sensor 15, and with the continuous movement of the roller 8, the roller 8 begins to extrude the third pressure sensor 15, so that the pressure collected by the third pressure sensor 15 gradually increases, until the roller 8 moves to the final position, that is, the foot support connecting plate 13 has been completely in the vertical state, indicating that the rider has put down the foot support and parked. In this process, the third pressure sensor 15 continuously feeds back the first pressure value it receives to the control center, and the first pressure value gradually increases, when the first pressure value is equal to or greater than the first threshold value, the control center can control the electric vehicle to be powered off, at this time the first threshold value corresponds to a certain intermediate transition position in the process of putting down the foot support, at this time it indicates that the rider has the intention to park, and the electric vehicle can be powered off to prevent the rider from touching the driving handle during parking, so that the electric vehicle is powered on and moves, at this time the rider who is in the parking action cannot hold the electric vehicle well and is easy to fall down; when the first pressure value is equal to or greater than the second threshold value, the control center controls the electric vehicle to be locked, at this time the second threshold value can be set to be slightly smaller than the maximum pressure value received by the third pressure sensor 15. When the rider completely puts down the foot support, the control center also controls the electric vehicle to be automatically powered off and locked, so there is no need to worry about the situation that the rider forgets to lock the vehicle, avoiding causing economic loss to the rider. In addition, for shared bicycles, after the electric vehicle is automatically powered off and locked, the control center can send a lock option to the mobile terminal, and the rider can select to temporarily park the electric vehicle in standby reservation state or directly return the vehicle to meet the various needs of shared electric vehicle parking, when a certain time is not selected, the state of the shared electric vehicle is directly set to the returned vehicle state, and the charging is calculated from the time when the vehicle is automatically locked. In addition, the third pressure sensor 15 is arranged on the connecting plate 1, rather than directly arranged on the surface of the foot support in contact with the ground, because after the foot support contacts the ground, the foot support bears the inclined weight of the electric vehicle, if the sensor is arranged at the bottom of the foot support, the sensor bears a larger pressure and is easy to be damaged, and at this time the state of the foot support of the electric vehicle is monitored by the pressure borne by the foot support, which is not very rigorous, when the bottom of the foot support is hit by external objects, a larger pressure will also be detected, which is easy to make the sensor arranged at the bottom of the foot support mistakenly think that the foot support has been put down, so that the control center sends a power-off instruction, which is not conducive to the rider during riding.And the trigger assembly monitors the real foot prop position state, directly converts the foot prop position state into pressure, and then into an electrical signal, so that the control center can monitor the real foot prop position; and the trigger assembly further converts the rotating pressure test mode of the foot prop connecting plate 13 into vertical pressure of the roller 8, avoiding direct contact between the foot prop connecting plate 13 and the third pressure sensor 15, because the foot prop connecting plate 13 will cause rotating extrusion to the third pressure sensor 15, and the third pressure sensor 15 is easy to be damaged after long time work.

[0053] In an embodiment of the present application, as Figure 1 , the car locking assembly further comprises a first sliding plate 16, a second elastic member 17 and a second sliding plate 19, the first sliding plate 16 and the second sliding plate 19 are slidingly installed in a sliding groove 18 on the side wall of the mounting seat, the two ends of the second elastic member 17 are respectively connected with the first sliding plate 16 and the second sliding plate 19, and the first sliding plate 16 is in contact with the third pressure sensor 15.

[0054] In the embodiment, the first sliding plate 16, the second elastic member 17 and the second sliding plate 19 constitute a buffer unit, the contact area between the first sliding plate 16 and the third pressure sensor 15 is larger than the contact area between the roller 8 and the third pressure sensor 15, and the first sliding plate 16 further converts the large pressure value into a smaller pressure value, so that the service life of the third pressure sensor 15 is prolonged.

[0055] In an embodiment of the present application, as Figure 1 and Figure 2 , the automatic power-off car locking device further comprises a power-off assembly, two of the power-off assemblies are symmetrically installed on the first mounting plate 2 and the second mounting plate 9, the power-off assembly comprises a base 4, a first pressure sensor 5, a first elastic member 6 and a sliding block 7, the first pressure sensor 5 is installed at the bottom of the base 4, the first pressure sensor 5 is used to be electrically connected with the control center, the first pressure sensor 5 is provided with the first elastic member 6, the first elastic member 6 is connected with the sliding block 7, and the sliding block 7 is slidingly installed in the base 4; two of the bases 4 are installed on the first mounting plate 2 and the second mounting plate 9, respectively, two of the sliding blocks 7 penetrate through the first mounting plate 2 and the second mounting plate 9, respectively, and are in contact with the roller 8.

[0056] In the embodiment, the power-off assembly is further added, when the roller 8 moves between the first mounting plate 2 and the second mounting plate 9, the roller 8 will extrude the sliders 7 on the upper and lower sides, so that the sliders 7 compress the first elastic member 6, the first pressure sensor 5 senses the pressure, and the collected second pressure value is fed back to the control center. When the foot support is lowered, the roller 8 is extruded between the two sliders 7, at this time the control center receives the second pressure value, and the control center can control the electric vehicle to be powered off when the second pressure value is received. However, in order to operate strictly, the control center can control the electric vehicle to be powered off only when the control center monitors that the first pressure value is equal to or greater than the first threshold value. At this time, it can be ensured that the roller 8 moves normally between the two mounting plates and moves to contact the third pressure sensor 15. At this time, it indicates that the foot support is normally lowered and has been lowered to a certain extent, preventing the first slide plate 16 from being stuck in the sliding groove 18 and causing incorrect operation. When the foot support is lifted, the control center receives that the first pressure value is less than the first threshold value and the control center receives the second pressure value fed back by the first pressure sensor 5. At this time, the electric vehicle is unlocked because the foot support has been lifted to a certain extent, and on the basis of the elastic structure of the foot support, the subsequent lifting action can be automatically lifted by the spring on the foot support. Therefore, the electric vehicle can be unlocked at this time.

[0057] In one embodiment of the application, as Figure 2 , the first mounting plate 2 is provided with a stop block 3, which is installed on the side of the pulley 8 away from the connecting plate 1, for limiting the rolling of the pulley 8 between the first mounting plate 2 and the second mounting plate 9. The stop block 3 can be long strip-shaped, installed on one side of the pulley 8, fixed with the first mounting plate 2, and the number of stop blocks 3 can also be multiple. Each stop block 3 is short in length, and the distance between adjacent two stop blocks 3 is less than the diameter of the pulley 8, preventing the pulley 8 from "escaping" between the two stop blocks 3 and leaving between the first mounting plate 2 and the second mounting plate 9, and ensuring the normal work of the pulley 8.

[0058] In one embodiment of the application, as Figure 2 and Figure 3 , the foot support connecting plate 13 is rotatably installed with the connecting plate 1 through the rotating shaft 10, the sleeve 11 is sleeved on the rotating shaft 10, the second pressure sensor 12 is installed on one end of the sleeve 11 close to the foot support connecting plate 13, the second pressure sensor 12 is in contact with the foot support connecting plate 13, and the second pressure sensor 12 is electrically connected with the control center.

[0059] The foot support connecting plate 13 is used for being connected with a foot support support rod, the foot support support rod comprises an upper support rod 20 and a lower support rod 21, and the upper support rod 20 and the lower support rod 21 are connected through a telescopic member 22.

[0060] In the embodiment, a second pressure sensor 12 is additionally arranged between the foot support and the vehicle body, so that the pressure of the vehicle body on the foot support can be monitored. The pressure collected by the second pressure sensor 12 can reflect the included angle between the vehicle body and the foot support. When the included angle is less than the foot support, the greater the pressure, the greater the included angle between the foot support and the vehicle body. Sometimes when parking, the parking position is mud or soft soil, and the foot support is easy to sink into the soil, so that the included angle between the vehicle body and the foot support becomes larger, and the pressure of the vehicle body on the foot support also becomes larger. At this time, the vehicle body is severely inclined, and is easy to roll over. When the control center receives the third pressure value fed back by the second pressure sensor 12 and the third pressure value is equal to or greater than the third threshold value, the telescopic part 22 is controlled to be elongated, so that the overall length of the foot support is increased, the electric vehicle is lifted, and the included angle between the foot support and the electric vehicle is reduced. In addition, the foot support may be just supported on a protrusion at some time, so that the original included angle between the foot support and the vehicle body is reduced. At this time, when the control center monitors that the third pressure value is less than the fourth threshold value, the control center can send a reminder information to the mobile terminal, reminding the rider that the position may cause the vehicle to fall down, and it is suggested to park in another place. The third threshold value and the fourth threshold value constitute a monitoring range of the third pressure value. When the third pressure value is in the monitoring range, it indicates that the position of the electric vehicle is good, and the probability of falling down is small. When the third pressure value is not in the monitoring range, the probability of the electric vehicle falling down is increased, and the user needs to be reminded or to correct the included angle between the electric vehicle and the foot support.

[0061] In addition, it should be noted that the elastic part can be selected from a spring, a compressible elastic foam pad or a silica gel pad, etc. As long as the selected part has compressibility and recoverability, it can be used as an elastic part. The telescopic part 22 is preferably an electric telescopic rod, and can also be a small automatic cylinder or an automatic oil cylinder, but the structure will be more complex.

[0062] Figure 4 The automatic power-off and locking control method flow chart in the embodiment of the application is shown. The automatic power-off and locking control method comprises:

[0063] Step 1: During the process of lowering the foot support, the pulley 8 approaches the third pressure sensor 15, the pressure on the third pressure sensor 15 gradually increases, and the third pressure sensor 15 feeds back the first pressure value collected to the control center.

[0064] Step 2: When the first pressure value is equal to or greater than the first threshold value, the control center controls the electric vehicle to be powered off.

[0065] Step 3: When the first pressure value is equal to or greater than the second threshold value, the control center controls the electric vehicle to be locked.

[0066] Step 4: the control center receives an activation signal from the mobile terminal and enters the starting stage;

[0067] Step 5: when the foot support is lifted, the pulley 8 moves away from the third pressure sensor 15, the pressure on the third pressure sensor 15 gradually decreases, and the third pressure sensor 15 feeds back the collected first pressure value to the control center;

[0068] Step 6: when the first pressure value is less than the first threshold value, the control center controls the electric vehicle to be unlocked;

[0069] Step 7: when the first pressure value is zero, the control center controls the electric vehicle to be powered on.

[0070] When the rider wants to stop, the foot support is lowered, the third pressure sensor 15 continuously feeds back the first pressure value to the control center, and the first pressure value gradually increases. When the first pressure value is equal to or greater than the first threshold value, the control center can control the electric vehicle to be powered off. At this time, the first threshold value corresponds to a certain intermediate transition position in the process of lowering the foot support. At this time, it means that the rider has the intention to stop, and the electric vehicle can be powered off. When the first pressure value is equal to or greater than the second threshold value, the control center controls the electric vehicle to be locked. When the rider lowers the foot support completely, the control center also controls the electric vehicle to be automatically powered off and locked. There is no need to worry about the situation that the rider forgets to lock the vehicle, and economic loss to the rider is avoided.

[0071] When the rider wants to ride the vehicle, the shared bicycle rider still needs to give the control center an activation signal through the mobile terminal scanning or other means. For the electric vehicle owned by the rider, the rider needs to send an activation signal to the control center through a wireless remote control or a key, etc. After the control center receives the activation signal, it enters the starting stage. At this time, the control center processes and judges the voltage value fed back by the third pressure sensor 15. When the first pressure value is less than the first threshold value, it means that the foot support has been lifted to a certain distance, and the electric vehicle can be unlocked. When the first pressure value is zero, it means that the roller 8 is separated from the third pressure sensor 15. At this time, the foot support is lifted to a larger amplitude, and the electric vehicle can be powered on, which is convenient for the rider to ride the vehicle next.

[0072] In an embodiment of the present application, when the first pressure value is equal to or greater than the first threshold value, the control center controls the electric vehicle to be powered off; and when the first pressure value is equal to or greater than the second threshold value, the control center controls the electric vehicle to be locked.

[0073] When the control center receives the second pressure value fed back by the first pressure sensor 5 and the first pressure value is equal to or greater than the first threshold value, the control center controls the electric vehicle to be powered off. On the basis of the original control, the monitoring of the second pressure value is added, and the second pressure value reflects the position state of the roller 8. When the second pressure value is not zero, it indicates that the roller 8 is always between the two sliders 7 and does not deviate from the slide rail, ensuring that the foot support is normally lifted and has been lifted to a certain extent. When the first pressure value is equal to or greater than the first threshold value, it indicates that the foot support has reached a vertical position, and the electric vehicle can be controlled to be powered off at this time.

[0074] When the first pressure value is equal to or greater than the second threshold value and the second pressure value is not zero, the control center controls the electric vehicle to be locked. The monitoring of the second pressure value not being zero is added to ensure that the roller 8 is always between the two mounting plates, ensuring that the foot support is normally and completely lowered.

[0075] In an embodiment of the present application, when the first pressure value is less than the first threshold value, the control center controls the electric vehicle to be unlocked; and when the first pressure value is zero, the control center controls the electric vehicle to be powered on, which includes:

[0076] When the first pressure value is less than the first threshold value and the control center receives the second pressure value, the control center controls the electric vehicle to be unlocked. At this time, the first pressure value is selected to be less than the first threshold value instead of the second threshold value because the second threshold value is equal to or greater than the first threshold value, and the second threshold value corresponds to a state in which the foot support is just lifted a little. At this time, the artificially applied lifting force is removed, and the foot support may recover to a vertical supporting state under the action of its own elastic force. Therefore, the first pressure value is selected to be less than the first threshold value, and the first threshold value corresponds to a state in which the foot support has been lifted to a certain extent. In addition, the monitoring of the second pressure value is added to prevent the roller 8 from slipping out. When the second pressure value is not monitored in this process, the control center can feed back maintenance information to the mobile terminal to remind the rider to timely maintain the automatic power-off and locking device.

[0077] When the first pressure value is zero and the second pressure value is zero, the control center controls the electric vehicle to be powered on. At this time, it indicates that the foot support is completely lifted, and the roller 8 moves out of the two sliders 7.

[0078] In an embodiment of the present application, the automatic power-off and locking control method further includes:

[0079] When the foot support is lowered, the second pressure sensor 12 is pressed by the foot support connecting plate 13 and feeds back the collected third pressure value to the control center. At this time, the third pressure value can reflect the pressure value of the vehicle body on the foot support.

[0080] The control center monitors whether the third pressure value is equal to or greater than a third threshold value; the third threshold value corresponds to the maximum value of the angle between the foot support and the vehicle body, when the angle is the maximum value, the vehicle body is in the critical safety range, and when the angle exceeds the maximum value, the probability of the vehicle body tipping over increases.

[0081] During the parking of the electric vehicle, when the third pressure value is equal to or greater than the third threshold value for the first time, the control center sends a start signal to the telescopic member 22 to control the telescopic member 22 to elongate. When the third pressure value is equal to or greater than the third threshold value for the first time, the angle between the vehicle body and the foot support can be corrected by controlling the telescopic member 22, but this correction is only allowed once to prevent the foot support from sinking too deep into the soil.

[0082] When the third pressure value is equal to or greater than the third threshold value again, the mobile terminal is sent a reminder message to facilitate the rider to change the parking position of the electric vehicle. When the control center monitors that the third pressure value is equal to or greater than the third threshold value again during the same parking period, the user needs to be notified to move the vehicle.

[0083] In an embodiment of the present application, an electric vehicle is also provided, which comprises the automatic power-off locking device and the control center described above, the control center is electrically connected with the sensor in the automatic power-off locking device, and the automatic power-off locking control method described above is executed to control the electric vehicle to automatically power off and lock when parking, thereby avoiding economic losses caused by the rider forgetting to lock the vehicle.

[0084] Although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that modifications can be made to the technical solutions described in the foregoing embodiments, or equivalent replacements can be made to part of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solution to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
