Description

Technical Field

[0001] The utility model relates to the technical field of access control systems, and specifically relates to a pedestrian protection structure for an access control system. Background Technique

[0002] An access control system is a security management system used to control access to doorways, and is usually applied to places such as enterprises, schools, and residential communities. It mainly restricts personnel from entering specific areas through various identity recognition technologies and access control devices, ensuring that only authorized personnel can enter.

[0003] Currently, the patent with the publication number CN114627585A discloses an intelligent community access control system, belonging to the technical field of access control. In this solution, a voiceprint receiving module is used to receive the voice of the owner to determine whether to open the automatic door. During the epidemic prevention period, there is no need for the owner to remove the mask for face recognition, reducing the spread of the epidemic. A liquid pump is used to extract a fixed amount of disinfectant and cooperate with an atomization module to atomize the disinfectant to disinfect the cyclone disinfection cover, reducing the virus transmission route and improving safety. An induced draft fan is used to accelerate the outward diffusion of the atomized disinfectant, and at the same time blow the offset fan blade to drive the rotating ring to rotate, and cooperate with the attraction of the electromagnet to the ferromagnetic body to control the angle between the communication hole of the sealing disk and the air guide hole of the isolation disk, thereby controlling the communication rate between the voiceprint receiving module and the outside world, effectively reducing the dust adhering to the voiceprint receiving module and affecting the receiving effect, and effectively avoiding damage to the voiceprint receiving module caused by excessive external volume.

[0004] However, the following problems still exist in the above-mentioned community access control system:

[0005] In the actual use process of the current community access control system, some pedestrians often, in order to save time, will follow through the access control together after the previous pedestrian opens the access control and before the access control is closed. This may cause the access control to clamp or even injure the following pedestrians, which is rather inconvenient. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a pedestrian protection structure for an access control system. When a pedestrian collides with the access control frame or the U-shaped bracket during the closing process of the access control frame, the induction mechanism will be triggered by the partition rod of the U-shaped bracket, and then through the transmission mechanism, the U-shaped bracket and the partition rod will be retracted into the access control frame, thereby increasing a safe space for a certain distance and avoiding the situation that the access control frame and the access control bracket clamp or injure pedestrians.

The ends of the partition rods far from the U-shaped bracket all penetrate the access control frame, and an induction mechanism is connected to the inner wall of the access control frame, and the induction mechanism is aligned with the partition rods. The inner wall of one of the chutes is connected with a transmission mechanism, and the output end of the transmission mechanism is connected to one end of the U-shaped bracket.

[0008] Further, the transmission mechanism includes a motor and a threaded rod. The outer wall of the motor is fixedly connected to the inner wall of the chute, the output shaft of the motor is fixedly connected to one end of the threaded rod, and the other end of the threaded rod is connected to one end of the U-shaped bracket.

[0009] Further, inner rods are slidably connected to the inner walls of the two chutes, and one ends of the two inner rods are respectively fixedly connected to the two ends of the U-shaped bracket located inside the chutes.

[0010] Further, a threaded hole is penetrated through the inner wall of one of the inner rods, and the outer wall of the threaded rod is threadedly connected to the inner wall of the threaded hole.

[0011] Further, the induction mechanism is located between the two glass sheets.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1-4 , A pedestrian protection structure of an access control system, including two access control brackets 1, an access control frame 2 installed between the two access control brackets 1, and two glass sheets 3 installed inside the access control frame 2. Two parallel slide grooves 201 are provided on one side of the access control frame 2. The two slide grooves 201 are respectively located at the upper and lower ends of the access control frame 2. The inner walls of the two slide grooves 201 are simultaneously connected to a U-shaped bracket 4. A plurality of partition rods 5 are fixedly connected to the outer wall of the U-shaped bracket 4 close to the access control frame 2. One end of each partition rod 5 away from the U-shaped bracket 4 penetrates through the access control frame 2. An induction mechanism is connected to the inner wall of the access control frame 2, and the induction mechanism is matched and aligned with the partition rod 5. A transmission mechanism is connected to the inner wall of one of the slide grooves 201, and the output end of the transmission mechanism is connected to one end of the U-shaped bracket 4.

[0023] The pedestrian protection structure of an access control system in the present utility model is similar to the existing access control system structure, such as a smart community access control system disclosed in the patent with the publication number CN114627585A. As Figures 1 to 4As shown, when the pedestrian protection structure of the access control system of the utility model is in normal use, the pedestrian opens the access control frame 2 by scanning the face, swiping the card, entering the password and other currently commonly used methods, and then the pedestrian passes through the safe area between the two access control brackets 1 normally; if there are other pedestrians at this time, for convenience and trouble, they do not open the access control frame 2 normally according to the above procedure, but choose to follow the last pedestrian through. At this time, after the first pedestrian passes, the U-shaped bracket 4 is in the process of turning back to close under the drive of the access control frame 2, and it is very likely to collide with the second pedestrian. At this time, in order to prevent the pedestrian from being clamped by the access control bracket 1 and the U-shaped bracket 4 Injury, when the U-shaped bracket 4 contacts the pedestrian, a collision reaction force will be generated in an instant, and this force will cause the U-shaped bracket 4 to shake. Because a sensing mechanism is arranged between the two glass sheets 3 inside the access control frame 2, this sensing mechanism will instantly transmit an electrical signal to the external processor after detecting the shaking of the U-shaped bracket 4 or the access control frame 2, and then start the transmission mechanism through the external controller. The transmission mechanism will quickly retract the U-shaped bracket 4 into the access control frame 2, reserving a safe space of a distance for the pedestrian, thereby preventing the pedestrian from being clamped between the U-shaped bracket 4 and the access control bracket 1 and being injured.

[0024] It should be noted here that the external processor and the external controller are both existing technologies, so they will not be described in detail.

[0025] Please refer to Figures 2-4 The transmission mechanism includes a motor 7 and a threaded rod 8. The outer wall of the motor 7 is fixedly connected to the inner wall of the slide slot 201. The output shaft of the motor 7 is fixedly connected to one end of the threaded rod 8. The other end of the threaded rod 8 is connected to one end of the U-shaped bracket 4. The inner walls of the two slide slots 201 are slidably connected with inner rods 6. One end of the two inner rods 6 is fixedly connected to the two ends of the U-shaped bracket 4 located in the slide slot 201. A threaded hole 601 is formed through the inner wall of one of the inner rods 6. The outer wall of the threaded rod 8 is threadedly connected to the inner wall of the threaded hole 601.

[0026] More specifically, when the sensing mechanism detects that the U-shaped bracket 4 is vibrating, the external controller turns on the motor 7, and the output shaft of the motor 7 drives the threaded rod 8 to rotate. After the threaded rod 8 rotates, it drives the inner rod 6 to slide toward the depth of the slide groove 201 along the threaded hole 601, and then the U-shaped bracket 4 can be retracted into the slide groove 201, thereby increasing the safety distance between the U-shaped bracket 4 and the access control bracket 1 and reducing the probability of pinching.

[0027] Please refer to Figure 2 and Figure 3 , the sensing mechanism is located between the two glass sheets 3.

[0028] More specifically, the sensing mechanism is arranged between two glass sheets 3. First, the glass sheets 3 can provide protection for the sensing mechanism, preventing it from being exposed to wind and rain. Second, since advertising sheets are usually pasted on the glass sheets 3, the sensing mechanism can also be blocked by the advertising sheets at this time, making it more aesthetically pleasing.

[0029] Please mainly refer to Figure 2 and Figure 3 , the sensing mechanism includes a support block 9 and a sensor 10. One side of the support block 9 is fixedly connected to the inner wall of the access control frame 2, the outer wall of the sensor 10 is fixedly connected to the inner wall of the support block 9, and the sensing end of the sensor 10 is aligned with the partition rod 5.

[0030] More specifically, when the U-shaped bracket 4 collides with a pedestrian, the shock force will be transmitted to the access control frame 2 through the partition rod 5 at this time. When the sensor 10 inside the access control frame 2 senses the vibration, it will instantly transmit this electrical signal to the external processor, and then the subsequent motor 7 can cooperate with the threaded rod 8 to retract the U-shaped bracket 4 into the sliding groove 201.

[0031] Flexible cloths are sleeved on the outer walls of the U-shaped bracket 4 and several partition rods 5. When the U-shaped bracket 4 collides with a pedestrian, by sleeving flexible cloths on the outside of the U-shaped bracket 4 and the partition rods 5, the impact feeling of direct contact with metal during the collision can be reduced.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
