[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1-5 , an electric vehicle identification and blocking alarm device in an elevator, comprising a wall 1, a fixed frame 2 is fixedly installed on the outer wall of the wall 1, a movable door 3 is arranged in the middle of the wall 1, a movable groove 5 is opened on the outer wall of the fixed frame 2, and the inner walls on both sides of the movable groove 5 are provided with limit grooves 14, a mounting groove 8 is opened in the middle of the fixed frame 2, and a motor 9, a controller 12 and a sounder 13 are fixedly installed on the top of the inner wall of the mounting groove 8, respectively, a transmission wheel 10 is fixedly sleeved on the output shaft of the motor 9, a transmission belt 11 is rollingly connected to the middle of the transmission wheel 10, a screw rod 15 is fixedly installed at the bottom of the transmission wheel 10, a lifting seat 6 is threadedly connected to the outer wall of the screw rod 15, a powerful motor 7 is fixedly installed in the middle of the lifting seat 6, and an interception strip 4 is fixedly installed on the output shaft of the powerful motor 7.
[0022] In the above structure, through the arrangement of the wall 1, the fixed frame 2, the movable door 3, the installation slot 8, the motor 9, the transmission wheel 10, the transmission belt 11, and the limit slot 14, after the alarm device is installed, when a person carries an electric vehicle through the movable door 3 to enter the elevator, the controller 12 will automatically control the powerful motor 7 to operate, so that the two interception bars 4 block the moving trajectory of the electric vehicle to ensure that the electric vehicle cannot enter the elevator, and then control the sounder 13 to make a sound, thereby achieving the effect of intelligent blocking and providing an alarm.
[0023] In a preferred embodiment: a groove is provided on the outer wall of the lifting seat 6 , one inner wall of the groove is fixedly assembled with the outer wall of the powerful motor 7 , and the other inner wall of the groove is rotatably connected with the outer wall of the intercepting bar 4 .
[0024] In the above structure, through the groove structure, when an electric vehicle is detected, the powerful motor 7 will be automatically controlled to operate, so as to ensure that the two interception bars 4 can rotate and dock, thereby preventing the electric vehicle from entering the elevator. The lifting seat 6 can also automatically change the height of the lifting seat 6 and the interception bar 4 when the person riding the elevator lifts the electric vehicle to ensure that the electric vehicle cannot enter the elevator, thereby improving the protection effect of the device and the safety during the elevator ride.
[0025] In a preferred embodiment, the inner walls of the movable groove 5 and the limiting groove 14 are both slidably connected to the outer wall of the lifting seat 6 , the number of the intercepting bars 4 is two, and the two intercepting bars 4 are symmetrically distributed along the outer wall of the fixed frame 2 .
[0026] In the above structure, by setting the movable groove 5 and the limit groove 14 structure, the lifting seat 6 will not be able to produce position deviation during the lifting process due to the limiting effect of the movable groove 5 and the limit groove 14. At the same time, the limit groove 14 will limit the rising height of the lifting seat 6, thereby ensuring that the intercepting bar 4 can be retracted after the lifting seat 6 rises, avoiding the situation that the people taking the elevator behind the blocked electric vehicle will also be blocked, thereby improving the practicality of the device.
[0027] In a preferred embodiment, a heat dissipation groove is provided on the inner wall of the mounting groove 8 , and the position of the heat dissipation groove corresponds to the position of the motor 9 .
[0028] In the above structure, by setting up the heat dissipation groove structure, the heat generated by the motor 9 during operation will be discharged to the outside of the device through the heat dissipation groove, thereby ensuring the normal operation of the motor 9 and reducing the probability of the motor 9 burning during operation, thereby ensuring the normal use of the device.
[0029] In a preferred embodiment: a sensor is also fixedly mounted on the top of the inner wall of the mounting groove 8, and the controller 12 is electrically connected to the sensor, the sound generator 13, the powerful motor 7 and the motor 9 respectively.
[0030] In the above structure, through the set sensor structure, the behavior of the passengers can be detected by using sensors, so as to ensure that the lifting seat 6 can adjust the height as the electric vehicle rises when the passengers carry the electric vehicle, thereby achieving the effect of blocking the electric vehicle from entering the elevator in a large range, and ensuring the safety of the elevator during riding.
[0031] In a preferred embodiment, there are two transmission wheels 10 , and the two transmission wheels 10 are connected via a transmission belt 11 .
[0032] In the above structure, through the transmission wheel 10 and the transmission belt 11 structure, when the motor 9 is in operation, it will drive one transmission wheel 10 to rotate, and the other transmission wheel 10 will rotate synchronously under the transmission effect of the transmission belt 11, thereby ensuring that the adjustment degree of the height of the two lifting seats 6 remains consistent, thereby improving the precise coordination of various accessories during the operation of the device and the energy utilization rate of the device.
[0033] Working principle: First, after the user assembles the device, when the passengers push the electric vehicle into the elevator, the controller 12 will automatically control the powerful motor 7 to rotate the interception bar 4, so that the two interception bars 4 can be docked. At this time, the electric vehicle cannot enter the elevator. At the same time, the controller 12 controls the sounder 13 to sound an alarm, thereby preventing the electric vehicle from entering the elevator. When the passengers carry a smaller electric vehicle to pass through the interception bar 4, the motor 9 is operated through the cooperation of the sensor and the controller 12, so that the lifting seat 6 drives the interception bar 4 to rise, thereby ensuring that the electric vehicle cannot enter the elevator, thereby improving the intelligence and practicality of the alarm device.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
