Description

Technical Field

[0001] This utility model relates to the field of access control technology, and more specifically, to an anti-collision device for access control poles. Background Technology

[0002] Access control barriers are facilities used to control the entry and exit of vehicles or pedestrians. They are typically installed at the entrances of parking lots, residential communities, office buildings, factories, and other similar locations. Their main function is to restrict the entry and exit of vehicles or pedestrians, and to identify, record, and manage those entering and exiting.

[0003] Patent authorization number CN221406523U discloses an access control lever lifting device, including a base, a chassis fixedly attached to the top surface of the base, a first rotating rod rotatably inserted into the front top of the chassis via a bearing, a main blocking rod fixedly sleeved on the outer surface of the first rotating rod, a groove formed on one side of the top surface of the main blocking rod, a second rotating rod rotatably disposed between the two sides of the inner wall of the groove, a second rotating rod fixedly sleeved on the surface of the second rotating rod, a first servo motor disposed inside the chassis, the output end of the first servo motor fixedly connected to the end of the first rotating rod, the main blocking rod can rotate by the drive of the first servo motor, and the main blocking rod has a drive structure inside that allows a secondary blocking rod to rotate independently. This utility model is equipped with a secondary blocking rod that can be operated independently, making the access control more flexible in use.

[0004] However, the barrier bar in patent authorization number CN221406523U does not have an anti-collision function. When a vehicle makes a mistake and comes into contact with the barrier bar, and the barrier bar is not fully raised, it may bend or even break, making the barrier bar unusable. In order to enable the barrier bar to have an anti-collision function, we have proposed an anti-collision device for access control bars to solve the above-mentioned problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] To address the problems existing in the prior art, the purpose of this utility model is to provide an anti-collision device for access control poles. This device can ensure that the access control pole body always maintains a safe distance from the vehicle, thereby effectively preventing the access control pole body from bending and breaking after being impacted, avoiding damage to the access control pole body, and enabling the access control pole body to have an anti-collision function.

[0007] 2. Technical Solution

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] An anti-collision device for an access control pole includes an access control pole body and a connecting seat for mounting the access control pole body. One end of the access control pole body is symmetrically equipped with first shaft heads that are rotatably connected to the connecting seat, and a driven gear is mounted on one of the first shaft heads.

[0010] The inner side of the connecting seat is rotatably connected to a driving gear that is interference-fitted with the driven gear. A bracket is mounted on the top of the connecting seat, and a servo motor is mounted on the top of the bracket. A drive shaft that passes through the bracket is mounted on the power output end of the servo motor, and the drive shaft is connected to the driving gear in a transmission manner.

[0011] Distance measuring radars are installed on both sides of the access control pole body;

[0012] A control host is installed on the outside of the connector.

[0013] Furthermore, a shaft hole is provided at the part where the connecting seat is combined with the first shaft head, and a bearing that is interference-fitted with the first shaft head is installed on the inner side of the shaft hole.

[0014] Furthermore, a second shaft head is welded to the surface of the drive gear and is rotatably connected to the connecting seat. A bearing is installed at the part where the second shaft head engages with the connecting seat.

[0015] Furthermore, the second shaft head passes through the connecting seat, and a coupling is installed between the through end of the second shaft head and the drive shaft.

[0016] Furthermore, multiple ranging radars are installed at equal intervals on the surface of the access control pole body.

[0017] Furthermore, the output terminal of the ranging radar is electrically connected to the input terminal of the control host, and the output terminal of the control host is electrically connected to the input terminal of the servo motor.

[0018] Furthermore, the port edge of the connector is symmetrically provided with notches corresponding to the part of the access control bar body.

[0019] 3. Beneficial effects

[0020] Compared with existing technologies, the advantages of this utility model are:

[0021] In this solution, after the ranging radar detects that the distance between the vehicle and the access control bar is less than the safe distance, the drive gear is driven to rotate by the transmission shaft of the servo motor mounted on the bracket. The meshing between the driven gear and the drive gear causes the first shaft head to rotate with the connecting seat, thereby causing the access control bar to rotate away from the vehicle. This ensures that the access control bar maintains a safe distance from the vehicle, effectively preventing the access control bar from bending and breaking after an impact, thus avoiding damage to the access control bar and giving it an anti-collision function.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] Please see Figure 1-6An anti-collision device for an access control pole includes an access control pole body 1 and a connecting seat 2 for mounting the access control pole body 1. One end of the access control pole body 1 is symmetrically mounted with a first shaft head 3 that is rotatably connected to the connecting seat 2. A driven gear 4 is mounted on one of the first shaft heads 3.

[0033] The inner side of the connecting seat 2 is rotatably connected to the driving gear 5, which is interference-fitted with the driven gear 4. The top of the connecting seat 2 is equipped with a bracket 7, and the top of the bracket 7 is equipped with a servo motor 8. The power output end of the servo motor 8 is equipped with a drive shaft 9 that passes through the bracket 7, and the drive shaft 9 is connected to the driving gear 5 in a transmission manner.

[0034] Distance measuring radars 11 are installed on both sides of the access control pole body 1;

[0035] The control host 12 is installed on the outside of the connector 2;

[0036] It should be noted that when the anti-collision device of the access control pole is in use, the detection distance of the ranging radar 11 is set to 15-20cm by the control host 12, and the forward and reverse rotation program of the servo motor 8 is set by the control host 12. When the ranging radar 11 detects that the distance between the vehicle and the access control pole body 1 is less than 15cm, the drive shaft 9 of the servo motor 8 installed on the bracket 7 drives the drive gear 5 to rotate. The driven gear 4 meshes with the drive gear 5, thereby causing the first shaft head 3 to rotate in conjunction with the connecting seat 2, and thus causing the access control pole body 1 to rotate away from the vehicle. This ensures that the access control pole body 1 always maintains a safe distance from the vehicle, thereby effectively preventing the access control pole body 1 from bending and breaking after being hit, avoiding damage to the access control pole body 1, and giving the access control pole body 1 an anti-collision function.

[0037] like Figure 1 , Figure 4 As shown, a shaft hole is provided at the part where the connecting seat 2 and the first shaft head 3 are combined, and a bearing that is interference-fitted with the first shaft head 3 is installed on the inner side of the shaft hole.

[0038] It should be noted that this reduces the friction between the first shaft head 3 and the connecting seat 2, and ensures the rotational accuracy of the access control rod body 1 in conjunction with the first shaft head 3 during the rotation process.

[0039] like Figure 5 , Figure 6 As shown, a second shaft head 6 is welded to the surface of the drive gear 5 and is rotatably connected to the connecting seat 2. A bearing is installed at the part where the second shaft head 6 is combined with the connecting seat 2. The second shaft head 6 passes through the connecting seat 2, and a coupling 10 is installed between the through end of the second shaft head 6 and the drive shaft 9.

[0040] It should be noted that while reducing the resistance during the rotation of the drive gear 5, the power transmitted by the servo motor 8 can be normally transmitted to the second shaft head 6 through the transmission shaft 9.

[0041] like Figure 1 As shown, multiple ranging radars 11 are installed at equal intervals on the surface of the access control pole body 1;

[0042] It should be noted that the measurement range of the access control pole body 1 can be increased by setting multiple ranging radars 11.

[0043] Furthermore, the output terminal of the ranging radar 11 is electrically connected to the input terminal of the control host 12, and the output terminal of the control host 12 is electrically connected to the input terminal of the servo motor 8.

[0044] It should be noted that the ranging radar 11 can be a TOF04LED model, and the control host 12 can be a J4125-IT-17CM model.

[0045] like Figure 1 As shown, notches are symmetrically provided on the edge of the port of the connector 2 corresponding to the part of the access control bar body 1;

[0046] It should be noted that by setting the notch, the access control bar body 1 can be rotated normally without interference.

[0047] In use: The detection distance of the ranging radar 11 is set to 15-20cm by the control host 12. At the same time, the control host 12 sets the forward and reverse rotation program for the servo motor 8. When the ranging radar 11 detects that the distance between the vehicle and the access control bar body 1 is less than 15cm, the drive shaft 9 of the servo motor 8 installed on the bracket 7 drives the drive gear 5 to rotate. The driven gear 4 meshes with the drive gear 5, thereby causing the first shaft head 3 to rotate in conjunction with the connecting seat 2, which in turn causes the access control bar body 1 to rotate away from the vehicle. This ensures that the access control bar body 1 always maintains a safe distance from the vehicle, thus effectively preventing the access control bar body 1 from bending and breaking after being hit, and avoiding damage to the access control bar body 1.

[0048] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
