Description

Technical Field

[0001] The utility model belongs to the technical field of elevators, and in particular relates to an elevator car that prohibits electric vehicles from entering. Background Art

[0002] Electric bicycles, also known as electric vehicles, have become an important means of transportation in people's lives. For residents, electric vehicles have low travel costs, and the energy of electric vehicles is green and environmentally friendly, making electric vehicles extremely popular. However, in real life, more and more people live in high-rise buildings. In order to prevent electric vehicles from being stolen or to use cheaper residential electricity, residents ride electric vehicles home or place them in the corridor through elevators. As we all know, electric vehicles now generally use lithium batteries with high energy density and more flammable. Therefore, electric vehicles entering high-rise residential buildings bring great safety hazards. Whether the electric vehicle is charged or not, there is a risk of flammability, which greatly affects the safety of life and property of residents.

[0003] In the prior art, a surveillance camera is installed on the top wall of the elevator car to identify whether an electric vehicle enters the elevator. When an electric vehicle enters the elevator car, an alarm is sounded and the elevator stops rising. Some elevators only sound an alarm, which does not affect the elevator's rise and cannot effectively prevent the elevator from entering high-rise residential buildings. An elevator that sounds an alarm and stops rising can prevent electric vehicles from rising, but it will affect other passengers using the elevator.

[0004] A Chinese patent (CN114394501A) discloses a method, device and elevator for monitoring electric vehicles prohibited from entering elevators. This technical solution optimizes the accuracy of the camera in identifying electric vehicles entering the elevator, but it is still impossible to prevent electric vehicles from entering the elevator by mechanical or physical means. Utility Model Content

[0005] In view of this, the utility model provides an elevator car that prohibits electric vehicles from entering, so as to solve the above-mentioned problem.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An elevator car that prohibits electric vehicles from entering, comprising: a car body, a monitoring camera, a handrail and a lifting drive device, wherein an elevator entrance is arranged on the car body, a lifting entrance is arranged on a side of the bottom wall of the car body close to the elevator entrance, the handrail is vertically slidably connected in the lifting entrance, the lifting drive device is installed at the bottom end of the car body, the output end of the lifting drive device is fixedly connected to the bottom end of the handrail, the monitoring camera is installed on the top wall of the car body, and the monitoring camera is electrically connected to the lifting drive device.

[0008] Furthermore, the lifting drive device includes an electric telescopic rod, a pair of the electric telescopic rods are fixedly installed at the bottom end of the carriage, first extension parts are provided on both sides of the bottom end of the railing, the output end of the electric telescopic rod is vertically downward and fixedly connected to the first extension part, and the electric telescopic rod is electrically connected to the surveillance camera.

[0009] Furthermore, a limiting portion is provided on the handrail, and the limiting portion abuts against the bottom end of the lifting opening to limit the handrail from rising to a maximum stroke.

[0010] Furthermore, the lifting drive device also includes a first pressure sensor, which is installed between the output end of the electric telescopic rod and the first extending portion, and the first pressure sensor is electrically connected to the electric telescopic rod.

[0011] Furthermore, second extensions are provided on both sides of the top of the railing, and limiting grooves are provided at both ends of the lifting opening, and the second extensions can be embedded in the limiting grooves to limit the railing from descending to a maximum stroke.

[0012] Furthermore, the lifting drive device also includes a second pressure sensor, which is installed between the second extension portion and the limiting groove, and the second pressure sensor is electrically connected to the electric telescopic rod.

[0013] The beneficial effects of the utility model are:

[0014] After the elevator car door is opened, the monitoring camera identifies the electric car at the elevator entrance, and then the two electric telescopic rods at the bottom of the car body are retracted, and the output end of the electric telescopic rod causes the handrail to rise from the lifting opening through the first extension part. When the limit part abuts against the lifting opening to achieve the rising limit of the handrail, the electric telescopic rod continues to shrink and the pulling force monitored by the first pressure sensor becomes larger, prompting the electric telescopic rod to stop further shrinking; after the monitoring camera identifies that the elevator car door is closed, the electric telescopic rod extends until the second extension part enters the limit groove, limiting the handrail from continuing to descend, and when the pressure monitored by the second pressure sensor becomes larger, the electric telescopic rod stops continuing to extend; the utility model can effectively prevent electric vehicles from entering the elevator car, thereby protecting the lives and property of residents.

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.

[0023] See attached Figure 1-4 As shown, the utility model provides an elevator car that prohibits electric vehicles from entering, including: a car body 1, a monitoring camera 2, a handrail 3 and a lifting drive device 4. The car body 1 is provided with an elevator entrance 5, and a pair of car doors 14 are slidably arranged on the outside of the elevator entrance 5. The driving of the car door 14 is a prior art and will not be described in detail here. A lifting entrance 6 is arranged on the bottom wall of the car body 1 on one side close to the elevator entrance 5, and the handrail 3 is vertically slidably connected in the lifting entrance 6. The lifting drive device 4 is installed at the bottom end of the car body 1, and the output end of the lifting drive device 4 is fixedly connected to the bottom end of the handrail 3. The monitoring camera 2 is installed on the top wall of the car body 1, and the monitoring camera 2 is electrically connected to the lifting drive device 4. After the monitoring camera 2 recognizes the electric vehicle at the elevator entrance 5, the lifting drive device 4 drives the handrail 3 to slide vertically upward in the lifting entrance 6, and the handrail 3 prevents the electric vehicle from entering the car body 1 at the elevator entrance 5.

[0024] In a preferred embodiment, the lifting drive device 4 includes an electric telescopic rod 8, a pair of electric telescopic rods 8 are fixedly installed at the bottom end of the car body 1, first extensions 7 are provided on both sides of the bottom end of the handrail 3, the output end of the electric telescopic rod 8 is vertically downward, and is fixedly connected to the first extension 7, and the electric telescopic rod 8 is electrically connected to the monitoring camera 2. After the monitoring camera 2 recognizes the electric vehicle at the elevator entrance 5, the electric telescopic rod 8 is retracted, and the output end of the electric telescopic rod 8 causes the handrail 3 to rise from the lifting entrance 6 through the first extension 7.

[0025] In a preferred embodiment, a limiting portion 9 is provided on the handrail 3. When the limiting portion 9 abuts against the lifting opening 6, the rising limit of the handrail 3 is realized, so that the handrail 3 rises to the maximum stroke.

[0026] In a preferred embodiment, the lifting drive device 4 further includes a first pressure sensor 10, which is installed between the output end of the electric telescopic rod 8 and the first extension portion 7, and is electrically connected to the electric telescopic rod 8. The electric telescopic rod 8 continues to contract, and the tension between the electric telescopic rod 8 and the first extension portion 7 monitored by the first pressure sensor 10 increases, prompting the electric telescopic rod 8 to stop further contraction.

[0027] In a preferred embodiment, the second extensions 11 are provided on both sides of the top of the railing 3, and the two ends of the lifting port 6 are provided with limit slots 12, and the second extensions 11 can be inserted into the limit slots 12 to limit the railing 3 from descending to the maximum stroke. The electric telescopic rod 8 is extended until the second extension 11 enters the limit slot 12, so as to limit the descending of the railing 3 and make the railing 3 descend to the maximum stroke.

[0028] In a preferred embodiment, the lifting drive device 4 further includes a second pressure sensor 13 , which is installed between the second extension portion 11 and the limiting groove 12 , and is electrically connected to the electric telescopic rod 8 .

[0029] When the electric telescopic rod 8 continues to extend, the pressure between the second extension portion 11 and the limiting groove 12 monitored by the second pressure sensor 13 increases, prompting the electric telescopic rod 8 to stop extending further.

[0030] Example 1

[0031] After the car door 14 is opened, the monitoring camera 2 identifies the electric vehicle at the elevator entrance 5, and then the two electric telescopic rods 8 at the bottom of the car body 1 are retracted, and the output end of the electric telescopic rod 8 causes the railing 3 to rise from the lift opening 6 through the first extension portion 7; when the limit portion 9 abuts against the lift opening 6, the rise limit of the railing 3 is achieved. At this time, the height to which the railing 3 rises can prevent the electric vehicle from entering the car body 1, and the electric telescopic rod 8 continues to retract, which increases the tension monitored by the first pressure sensor 10, prompting the electric telescopic rod 8 to stop further retraction;

[0032] When the monitoring camera 2 recognizes that the car door 14 is closed, the electric telescopic rod 8 extends until the second extension portion 11 enters the limit groove 12. At this time, the top wall of the handrail 3 is flush with the bottom wall of the car body 1, preventing the handrail 3 from tripping the elevator user due to the height difference between the handrail 3 and the bottom wall of the car body 1; the handrail 3 is restricted from continuing to descend, and when the pressure monitored by the second pressure sensor 13 becomes larger, the electric telescopic rod 8 stops extending further.
