[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0032] In the utility model, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance, and are not limited as the order.

[0033] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "fixing" and the like should be understood broadly, for example, can be fixed connection, or can be detachable connection, or can be integrated; can be mechanical connection, or can be electrical connection; can be directly connected, or can be indirectly connected through intermediate medium, can be the communication inside two elements or the interaction relationship of two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0034] Please refer to Figure 1 and Figure 2 , the utility model preferred embodiment provides a barrier gate, including casing 1, license plate recognition component 2, electric control component 3, gate core component 4 and gate rod 5. License plate recognition component 2, electric control component 3 and gate core component 4 are all arranged in casing 1, license plate recognition component 2 is used to identify license plate, gate core component 4 is connected to gate rod 5, so that gate rod 5 is converted between horizontal and vertical. When gate rod 5 is in horizontal position, vehicle is prohibited to pass through;Gate rod 5 is in vertical position, and vehicle is allowed to pass through. Electric control component 3 is electrically connected to license plate recognition component 2 and gate core component 4, for recording license plate and controlling gate core component 4 to operate.

[0035] As Figure 3 , Figure 4 and Figure 5As shown, the gate core assembly 4 comprises a support frame 41, a motor 42, a main shaft 43, a driving arm 44 and a buffer arm 45. The support frame 41 comprises a support plate 411 and two bearing seats 412, which are fixed to the upper surface of the support plate 411 and located at the two side edges of the support plate 411 respectively, so as to increase the space between the two bearing seats 412.

[0036] The main shaft 43 is a hollow circular tube structure and is connected to the two bearing seats 412 in the axial direction. Since the bearing seats 412 are located at the two side edges of the support plate 411 respectively, the structure of the support plate 411 can be fully utilized to increase the size of the main shaft 43 between the two bearing seats 412 and improve the rotation stability.

[0037] The driving arm 44 and the buffer arm 45 are arranged in the axial direction of the main shaft 43 and both are located between the two bearing seats 412. One end of the driving arm 44 is clamped to the outer periphery of the main shaft 43 and the other end is connected to the motor 42 through a connecting rod mechanism 46. One end of the buffer arm 45 is clamped to the outer periphery of the main shaft 43 and the other end is connected to a spring mechanism 47.

[0038] The main shaft 43 is a hollow circular tube structure, which can improve the structural strength and increase the outer periphery size of the main shaft 43. The driving arm 44 and the buffer arm 45 are both clamped to the outer periphery of the main shaft 43, which can improve the connection area between the main shaft 43 and the driving arm 44 and the buffer arm 45 and improve the connection reliability, thereby effectively improving the transmission stability and reliability and facilitating the driving arm 44 and the buffer arm 45 to exert force on the main shaft 43.

[0039] One end of the main shaft 43 is connected to the gate lever 5. The one end of the main shaft 43 extends to the outside of the casing 1 and the gate lever 5 is located outside the casing 1.

[0040] The motor 42 is fixed to the lower surface of the support plate 411 and the support frame can connect each part of the gate core assembly into a whole, which is convenient for overall assembly into the casing 1. The motor 42 is connected to the main shaft 43 through the connecting rod mechanism 46 to drive the main shaft 43 to rotate, thereby driving the gate lever 5 to rotate, so that the gate lever 5 rotates between the vertical position and the horizontal position, thereby opening or closing the travel path.

[0041] The driving arm 44 and the buffer arm 45 are both arranged between the two bearing seats 412, so that the driving force of the motor 42 acts on the part of the main shaft 43 between the two bearing seats 412, and the two bearing seats 412 are relatively balanced under stress, thereby ensuring the stability of the rotation of the main shaft 43.

[0042] The two edges of the support plate 411 adjacent to the bearing seat 412 are called first edges 411a, and the two first edges 411a are bent upward to form a vertical plate 413; the two opposite edges of the support plate 411 located between the two bearing seats 412 are called second edges 411b, and the two second edges 411b are provided with bolts for connection with the housing 1. The vertical plate 413 can improve the structural strength at the first edge 411a, and after the second edge 411b is fixedly connected to the housing 1 by bolts, the housing 1 can further improve the structural strength at the second edge 411b, thereby making the overall structural strength of the support plate 411 greater, and thus ensuring the stability of the operation of the gate core assembly 4.

[0043] The gate arm 5 is parallel to the active arm 44 to facilitate their positioning and assembly connection on the main shaft 43. The active arm 44 and the gate arm 5 can switch between horizontal and vertical positions simultaneously.

[0044] The spring mechanism 47 provides elastic force to the buffer arm 45, causing the buffer arm 45 to drive the main shaft 43 and the gate arm 5 to move vertically, thereby reducing the load on the motor when the gate arm 5 is lifted. In this embodiment, the spring mechanism 47 consists of multiple parallel tension springs, each arranged vertically. When the gate arm 5 is in a horizontal state, the spring mechanism 47 is stretched to provide force to the buffer arm 45.

[0045] The spring mechanism 47 is located below the buffer arm 45, and the angle α between the length direction of the buffer arm 45 and the length direction of the gate arm 5 is an acute angle. When the gate arm 5 rotates, the buffer arm 45 is always located on the same side of the main shaft 43 in the horizontal direction, so that when the buffer arm 45 rotates, the other end of the buffer arm 45 has a larger vertical displacement and a smaller horizontal displacement. This makes the vertical displacement of the buffer arm 45 basically consistent with the deformation direction of the spring mechanism 47, which is beneficial to the deformation of the spring mechanism 47 and reduces the sway of the spring mechanism 47, thereby ensuring the stability and reliability of the gate core assembly 4 during rotation. Preferably, the angle α between the length direction of the buffer arm 45 and the length direction of the gate arm 5 is 35°-45°.

[0046] like Figure 6 As shown, keyways 430 are provided on the main spindle 43 at positions corresponding to the buffer arm 45 and the gate rod 5, and keys 431 are provided in the keyways 430. The buffer arm 45 and the gate rod 5 are connected to the main spindle 43 via the keys 431. The keyways 430 and the keys 431 facilitate the positioning and assembly of the buffer arm 45 and the gate rod 5, ensuring that their length directions maintain a preset angle.

[0047] The gate core assembly 4 also includes a sensing module located axially along the main shaft 43 between the buffer arm 45 and the active arm 44. The buffer arm 45 and the active arm 44 are located on one side of the main shaft 43 in the horizontal direction, while the sensing module is located on the other side of the main shaft 43 in the horizontal direction, to fully utilize space and make the structure more compact. Figure 4 , Figure 5 As shown, the sensing module includes a positioning plate 481, two sensors 482, and two sensing plates 483. The positioning plate 481 is vertically fixed to the upper surface of the support plate 411. Both sensors 482 are fixed to the positioning plate 481 and arranged along the axial direction of the main shaft 43. The two sensing plates 483 are located on the main shaft 43 and respectively cooperate with the two sensors 482 to detect the two position states of the gate arm 5. Through the cooperation of the two sensing plates 483 and the two sensors 482, the two positions of the gate arm 5 can be effectively monitored, ensuring the reliability of the detection.

[0048] like Figure 2 As shown, the housing 1 includes a shell 11 and a door 12. The license plate recognition component 2, the gate core component 4, and the electronic control component 3 are arranged vertically within the shell 11. The door 12 is rotatably mounted on the shell 11 with its rotation axis vertical. The top of the door 12 is higher than the license plate recognition component 2, and the bottom is lower than the electronic control component 3, allowing the door 12 to cover the license plate recognition component 2, the gate core component 4, and the electronic control component 3. By rotating the door 12, the housing 1 can be opened, exposing the license plate recognition component 2, the gate core component 4, and the electronic control component 3 for maintenance. A display screen 18 is provided on the door 12 at the position corresponding to the gate core component 4. By mounting the display screen 18 on the door 12, opening the door 12 exposes the back of the display screen 18 for maintenance.

[0049] The barrier gate provided in the second embodiment of this utility model differs from that in the first embodiment in that the gate arm 5 is described in detail below.

[0050] like Figure 7 and Figure 8 As shown, the gate arm 5 includes a rotating rod 51, a telescopic rod 52, and a telescopic drive mechanism 53. The rotating rod 51 is a hollow structure and is connected to the main shaft 43. The parts of the rotating rod 51 located on both sides of the main shaft 43 are the first rod 511 and the second rod 512, respectively.

[0051] The telescopic rod 52 is sleeved in the rotating rod 51, and the telescopic driving mechanism 53 is connected to the telescopic rod 52 to drive the telescopic rod 52 to move along the rotating rod 51. When the gate lever 5 rotates to the horizontal position, the telescopic rod 52 can be driven by the telescopic driving mechanism 53 to move along the rotating rod 51, so as to switch the gate lever 5 between the extended state and the retracted state. When the gate lever 5 is in the extended state, the outer end of the telescopic rod 52 moves out of the rotating rod 51, and the inner end of the telescopic rod 52 is located at the first rod 511, so that the gate lever 5 is unfolded; when the gate lever 5 is in the retracted state, the inner end of the telescopic rod 52 moves to the second rod 512, and the gate lever 5 can be rotated under the drive of the main shaft 43.

[0052] By moving the telescopic rod 52 on the rotating rod 51, the overall length of the gate lever 5 can be changed. When the gate lever 5 is in the extended state, the outer end of the telescopic rod 52 moves out of the rotating rod 51, so that the gate lever 5 is in a state of greater length, so as to play a role in closing the vehicle passage.

[0053] When the gate lever 5 is in the retracted state, the inner end of the telescopic rod 52 is located at the second rod 512, so that part of the weight of the telescopic rod 52 is located at the second rod 512, reducing the weight of the telescopic rod 52 at the first rod 511, thereby reducing the torque of the telescopic rod 52 acting on the main shaft 43, reducing the required force when the main shaft 43 rotates, facilitating the rotation of the main shaft 43, and reducing the burden of the motor 42. The gate lever 5 is especially suitable for a situation with a greater length, such as a length of more than 5 meters.

[0054] The telescopic rod 52 is a hollow tubular structure, and the thickness of the pipe wall at the inner end of the telescopic rod 52 is greater than the thickness of the pipe wall at the outer end of the telescopic rod 52, so as to offset the position of the center of gravity of the telescopic rod 52 to the inner end, thereby reducing the torque of the telescopic rod 52 acting on the main shaft. The pipe wall at the inner end of the telescopic rod 52 is thicker, which can improve the connection strength between the inner end of the telescopic rod 52 and the second rod 512 when the gate lever 5 is in the extended state.

[0055] The length of the telescopic rod 52 is 0.8-1 times the length of the rotating rod 51, so that the telescopic rod 52 is relatively short relative to the rotating rod 51, so that the length of the gate lever 5 in the retracted state is not less than half of the length in the unfolded state, so that the blocking effect on vehicle passage can still be achieved in the retracted state.

[0056] The telescopic driving mechanism 53 is electrically connected to the electric control assembly 3 to drive the telescopic rod 52 to move under the control of the electric control assembly 3. The telescopic driving mechanism 53 can include a telescopic motor 531, a transmission rope 532, and two rollers 533, which are respectively arranged on the first rod 511 and the second rod 512. The transmission rope 532 is annular and is sleeved on the two rollers 533. The inner end of the telescopic rod 52 is connected to the transmission rope 532, and the telescopic motor 531 is connected to the transmission rope 532 to drive the transmission rope 532 to move, thereby driving the telescopic rod 52 to move.

[0057] Further, the telescopic motor 531 can be arranged in the main shaft 43. The hollow structure of the main shaft 43 can accommodate the telescopic motor 531, so that the space can be fully utilized, and the circuit connection between the telescopic motor 531 and the electric control assembly 3 can be facilitated.

[0058] The transmission rope 532 can be clamped with the telescopic rod 52 through a clamping block 534 to facilitate assembly. The transmission rope and the output shaft of the telescopic motor can be connected through a transmission wheel set 535 to facilitate the telescopic motor to drive the transmission rope to move.

[0059] The rotating rod 51 includes two half-pipes 510 that are abutted and arranged along the axial direction of the main shaft. The two half-pipes 510 are abutted to form a rotating pipe to facilitate the assembly of the telescopic rod 52 to the rotating rod 51. The transmission rope 532 and the two rollers 533 can be arranged on one of the half-pipes to facilitate the assembly and connection of the rotating rod 51, and to facilitate the connection between the telescopic rod 52 and the transmission rope 532.

[0060] Here, in other embodiments, the telescopic motor 531 can be arranged at the end of the second rod 512 away from the first rod 511 to utilize the gravity of the telescopic motor 531 acting on the second rod 512, so that the force difference between the two sides of the main shaft 43 is reduced, and the required spring force of the spring mechanism 47 can be reduced, and the number of tension springs used can be reduced.

[0061] In another implementation of the telescopic driving mechanism, as shown in Figure 9 The telescopic driving mechanism includes an air pump 539 and an air pipe 536. The inner end of the telescopic rod 52 is sealingly fitted with the inner wall of the rotating rod 51. The end of the second rod 512 away from the first rod 511 is communicated with the air pump 539 through the air pipe 536 to push the telescopic rod 52 to move by changing the air pressure between the inner end of the telescopic rod 52 and the rotating rod 51.

[0062] The air pump 539 pumps air into the second rod 512 to push the telescopic rod 52 to extend, and the air pump 539 compresses the air in the second rod 512 to make the telescopic rod 52 move towards the second rod 512 and thus retract, so that the telescopic rod 52 moves by the air pressure change generated by the air pump 539. The air pipe 536 can be various hoses arranged in the main shaft 43 or use the inner cavity of the main shaft 43 as part of the air pipe to use the hollow structure of the main shaft 43 to set the telescopic drive mechanism, and the air pipe 536 can rotate with the main shaft 43. The air pump 539 is arranged in the shell 1, so that a larger power air pump 539 can be arranged in the shell 1.

[0063] As can be seen from the above two specific embodiments of the telescopic drive mechanism, at least part of the structure of the telescopic drive mechanism is arranged in the main shaft 43 to make full use of the space in the main shaft 43.

[0064] The use method of the barrier gate provided in the second embodiment of the utility model is as follows.

[0065] In the initial state, the barrier rod 5 is in a horizontal position and in an unfolded state to close the driving passage.

[0066] In step S200, whether a vehicle is coming is detected. If no vehicle is detected, the barrier rod 5 remains unchanged. If a vehicle is detected, the next step is performed.

[0067] In step S300, the inner end of the telescopic rod 52 is moved to the second rod 512 to make the barrier rod 5 in a retracted state, and the vehicle license plate information is identified.

[0068] In this step, a radar, an inductor or other means can be arranged to detect whether a vehicle is coming, or the camera of the license plate recognition assembly 2 can be used to detect the image screen to detect whether a vehicle is coming.

[0069] When a vehicle comes, the electric control assembly 3 controls the telescopic drive mechanism to move, so that the inner end of the telescopic rod 52 moves to the second rod 512 to reduce the force of the barrier rod 5 on the main shaft 43, thereby facilitating the rotation of the main shaft 43.

[0070] In step S400, after the license plate information is obtained, the main shaft 43 drives the barrier rod 5 to rotate to a vertical position, thereby opening the driving passage.

[0071] After the license plate recognition assembly 2 analyzes the vehicle image information, the license plate information is extracted. The license plate information is transmitted to the electric control assembly 3 for vehicle registration or parking fee settlement, the electric control assembly 3 controls the motor 42 to operate, and the main shaft 43 drives the barrier rod 5 to rotate.

[0072] In step S500, after the vehicle passes through the barrier gate, the main shaft 43 drives the barrier rod 5 to rotate to a horizontal position.

[0073] Step S600, control the telescopic rod 52 to extend, so that the gate bar 5 is in the stretched state.

[0074] After the vehicle passes through the driving passage, the electric control assembly 3 is used to perform the operation of closing the driving passage, the gate bar 5 is first rotated to the horizontal position, then the telescopic rod 52 is moved to stretch the gate bar 5, so that the driving passage is completely closed.

[0075] The barrier gate provided by the utility model, after the telescopic rod 52 is retracted, the overall rotation of the gate bar 5 is carried out, the torque of the gate bar 5 acting on the main shaft 43 can be reduced, the acting force of the motor 42 is reduced, the rotation of the gate bar 5 is facilitated, and then the elastic force of the required spring mechanism 47 can be reduced, so that the cost is reduced. The telescopic movement of the telescopic rod 52 is carried out at the horizontal position of the gate bar 5, the smoothness of the telescopic movement can be ensured, and the overall operation stability and reliability are improved. The retracting action of the telescopic rod 52 is carried out at the same time as the license plate information recognition, and the passing efficiency can be improved.

[0076] To sum up, although the utility model has disclosed the above-mentioned preferred embodiments, the above-mentioned preferred embodiments are not used to limit the utility model, and the ordinary skilled in the art can make various changes and decorations without departing from the spirit and scope of the utility model, therefore the protection scope of the utility model is subject to the range defined by the claims.
