[0057] Next, the solutions in the embodiments of the present utility model will be clearly and completely described with reference to 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.

Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0061] Referring to Figure 1 , the present utility model provides a barrier gate machine core, comprising:

[0062] A mounting member 1, the mounting member 1 includes a first surface and a second surface, and the first surface and the second surface are oppositely arranged at a vertical interval;

[0063] At least one mounting seat 2, the mounting seat 2 is arranged on the first surface;

[0064] A driven rotating shaft 3, the driven rotating shaft 3 is rotatably connected to the mounting seat 2, and one end of the driven rotating shaft 3 is used for connecting to a gate rod 400 to drive the gate rod 400 to move;

[0065] A motor 4, the motor 4 is arranged on the second surface, the output shaft of the motor 4 is arranged vertically, and the output shaft of the motor 4 is drivingly connected to the driven rotating shaft 3 to drive the driven rotating shaft 3 to drive the gate rod 400 to rotate.

[0066] In this embodiment, the barrier gate machine core of the present application drives the driven rotating shaft 3 through the motor 4, and the driven rotating shaft 3 drives the gate rod connected to the driven rotating shaft 3 to move. Further, the output shaft of the motor 4 is arranged vertically and is drivingly connected to the driven rotating shaft 3. When the motor 4 works, its output shaft rotates, and through transmission, it drives the driven rotating shaft 3 to rotate, so that the gate rod connected to the driven rotating shaft 3 rotates, enabling the gate rod to rise or fall when needed, playing a role in controlling passage.

[0067] The motor 4 is mounted on the second surface, and the output shaft of the motor 4 is arranged vertically and is drivingly connected to the driven rotating shaft 3. The driven rotating shaft 3 is rotatably connected to the first surface through the mounting seat 2. One end of the driven rotating shaft 3 is connected to the gate rod 400.

[0068] When it is necessary to open or close the barrier gate, the motor 4 can be controlled by a controller to start working, and the output shaft of the motor 4 starts to rotate. Since there is a driving connection between the output shaft and the driven rotating shaft 3, the rotation of the output shaft drives the driven rotating shaft 3 to rotate together.

[0069] The rotation of the driven rotating shaft 3 directly causes the gate rod 400 connected thereto to move, thereby realizing the opening or closing of the barrier gate.

[0070] The present application achieves the following effects by vertically arranging the output shaft of the motor 4 of the gate mechanism:

[0071] First, the reduction of floor space:

[0072] In the related art, the motor 4, the reducer and the driving shaft are arranged horizontally in sequence, which means that the length of the entire barrier gate movement will be lengthened due to the horizontal layout of these components, increasing the overall floor space of the barrier gate.

[0073] In the present application, the output shaft of the motor 4 is arranged vertically, so that the motor 4 can be connected to the driven shaft 3 in a vertical direction, thereby avoiding the space waste of horizontal arrangement. The vertical layout greatly shortens the horizontal length of the gate mechanism, thereby reducing the horizontal space required for the gate during installation.

[0074] Second, the reduction in volume:

[0075] The horizontal setting structure of the related art needs to reserve enough space for each horizontally arranged component, which will cause the entire movement to be larger in size, which not only increases the material cost but also takes up more installation space.

[0076] The vertical layout of the present application enables the transmission between the motor 4 and the driven shaft 3 to be arranged more compactly. This compact design effectively utilizes the vertical space of the gate mechanism instead of relying solely on the horizontal space, so it can accommodate the same or even more functional components without increasing the volume.

[0077] Third, installation flexibility is improved: the reduced footprint and smaller size mean that the barrier movement is more flexible during installation, especially suitable for occasions with limited installation space (such as narrow driveway entrances or parking lots with limited space).

[0078] Fourth, aesthetics and maintenance convenience: The smaller size allows the barrier shell to be designed to be more compact and beautiful. In addition, the simplification of the internal structure also makes maintenance and repair more convenient, reducing the difficulty of disassembly and inspection.

[0079] In summary, the present application solution vertically arranges the driven shaft 3 and the driving device on the first surface and the second surface of the mounting member, and further arranges a motor 4 arranged vertically at the output end, and the motor 4 is connected to the driven shaft 3 in a transmission manner, and is used to drive the driven shaft 3 to drive the gate rod to rotate. The output shaft of the motor 4 of the present application solution is arranged vertically, which can reduce the horizontal size of the gate mechanism, thereby reducing the floor space and volume of the gate using the gate mechanism of the present application solution, and effectively saving space.

[0080] Reference Figure 2, in some embodiments, the barrier gate machine core proposed in the embodiments of the present utility model further includes a transmission mechanism 5, and the transmission mechanism 5 is drivingly connected between the output shaft of the motor 4 and the driven rotating shaft 3 for driving the driven rotating shaft 3 to rotate under the drive of the motor 4;

[0081] The transmission mechanism 5 includes:

[0082] A driving rotating shaft 51, drivingly connected to the output shaft of the motor 4;

[0083] A driving swing arm 52, the first end of the driving swing arm 52 is fixedly connected to the driving rotating shaft 51;

[0084] A driven swing arm 53, the first end of the driven swing arm 53 is fixedly connected to the driven rotating shaft 3;

[0085] A connecting rod 54, the first end of the connecting rod 54 is rotatably connected to the second end of the driving swing arm 52, and the second end of the connecting rod 54 is rotatably connected to the second end of the driven swing arm 53;

[0086] Wherein, the driving swing arm 52 is arranged between the connecting rod 54 and the motor 4 in the axial direction of the driving rotating shaft 51.

[0087] In this embodiment, the core design of the transmission mechanism 5 is to use a linkage mechanism composed of a driving rotating shaft, a driving swing arm, a driven swing arm and a connecting rod to convert the rotational motion of the output shaft of the motor 4 into the rotational motion for driving the driven rotating shaft. Through the coordinated work of the driving rotating shaft, the driving swing arm, the driven swing arm and the connecting rod, it is ensured that the motor 4 can control the barrier rod.

[0088] The working process of the transmission mechanism proposed in the solution of the present application is as follows:

[0089] When it is necessary to raise the barrier rod to let the vehicle pass or lower the barrier rod to block the vehicle, the motor 4 works, its output shaft moves, and the force output by the output shaft of the motor 4 is transmitted to the driving rotating shaft 51 through driving connection, the driving rotating shaft 51 rotates, and the rotation of the driving rotating shaft 51 will drive the driving swing arm 52 fixedly connected thereto to swing accordingly.

[0090] The second end of the driving swing arm 52 is rotatably connected to one end of the connecting rod 54. When the driving swing arm 52 swings, the connecting rod swings or rotates around the driving rotating shaft accordingly. The movement of the driven swing arm 53 drives the driven rotating shaft 3 to rotate, and the rotational motion of the driven rotating shaft is transmitted to the barrier rod, so that the barrier rod rises or falls when needed.

[0091] The solution of the present application realizes the following effects by setting the transmission mechanism with the above structure:

[0092] Improvement of transmission efficiency: Through the design of the connecting rod and the swing arm, this transmission mechanism can effectively transmit the rotational motion of the motor 4 to the driven rotating shaft. The cooperation between the swing arm and the connecting rod reduces the energy loss during the transmission process and improves the overall transmission efficiency.

[0093] Stability and smoothness of motion: Linkage mechanisms are commonly used to achieve smooth and uniform motion transmission. This design ensures that the gate rod can maintain stable and smooth motion during the lifting and lowering process, reducing jitter and noise caused by uneven motion.

[0094] Compact structure: The transmission mechanism 5 is driven by a vertical swing arm and a connecting rod, utilizing the space in the vertical direction, effectively shortening the horizontal length of the movement mechanism, making the overall structure of the gate movement mechanism more compact. At the same time, since the active swing arm 52 is axially arranged between the connecting rod 54 and the motor 4 on the active rotating shaft 51, such a layout reduces the mutual interference between components and further optimizes the space utilization rate.

[0095] Flexible torque control: The lengths and angles of the swing arm and the connecting rod can be adjusted according to the design requirements, thereby controlling the torque generated during the transmission process. This means that the parameters of the transmission mechanism can be adjusted according to the weight and length of the gate rod to provide appropriate driving force and avoid overloading or insufficiency.

[0096] In summary, the transmission mechanism 5 in this embodiment efficiently and stably transmits the rotational motion of the motor 4 to the driven rotating shaft through the linkage design of the active rotating shaft, the swing arm, and the connecting rod, realizing the smooth control of the gate rod. This transmission design not only improves the transmission efficiency and the smoothness of motion but also makes the movement mechanism structure more compact, which is suitable for gate systems with limited space and high reliability requirements.

[0097] Refer to Figure 2 and Figure 3 , in some embodiments, the gate movement mechanism proposed in the embodiment of the present utility model further includes a speed reducer 6, and the speed reducer 6 is arranged between the second surface and the motor 4;

[0098] The speed reducer 6 includes:

[0099] A speed reduction input shaft 61, the speed reduction input shaft 61 is vertically arranged on the side of the speed reducer 6 facing away from the second surface, the output shaft of the motor 4 is arranged facing the second surface, and the speed reduction input shaft 61 is in transmission connection with or integrally formed with the output shaft of the motor 4;

[0100] An output transmission shaft 62, which is in transmission connection with the speed reduction input shaft 61 and the active rotating shaft 51;

[0101] The active swing arm 52 is axially arranged between the connecting rod 54 and the output transmission shaft 62 on the active rotating shaft 51.

[0102] In this embodiment, the speed reducer 6 can convert the high-speed rotational motion of the motor 4 into a low-speed, high-torque output through the internal gear set or other speed reduction devices. This speed reduction effect makes the barrier gate operate more smoothly during operation and can better meet the high-torque requirements when the barrier rod is opened or closed.

[0103] The output shaft of the motor 4 is arranged towards the second surface and is in transmission connection or integrally formed with the speed reduction input shaft 61 of the speed reducer 6. When the motor 4 starts, its output shaft transmits the power of high-speed rotation to the speed reduction input shaft 61.

[0104] Inside the speed reducer 6, the high-speed rotation of the speed reduction input shaft 61 is converted into a low-speed, high-torque motion through speed reduction devices such as a gear set. This speed reduction effect can significantly increase the torque, thus ensuring that sufficient force can still be provided to drive the driven rotating shaft and the barrier rod at a low speed.

[0105] The decelerated power is transmitted to the driving rotating shaft 51 through the output transmission shaft 62 of the speed reducer. Due to the lower output speed and larger torque after deceleration, the driving rotating shaft 51 can rotate in a slower but more powerful manner, thus stably driving the driving swing arm 52.

[0106] The driving swing arm 52 is fixedly connected to the driving rotating shaft 51 and is axially arranged between the connecting rod 54 and the output transmission shaft 62. When the driving rotating shaft 51 rotates under the condition of increased torque, the driving swing arm 52 drives the driven swing arm 53 through the connecting rod 54, and then drives the driven rotating shaft 3 to realize the lifting motion of the barrier rod 400.

[0107] The solution of this application realizes the following effects by setting the speed reducer 6 with the above structure:

[0108] Torque enhancement: By introducing the speed reducer 6, the high rotational speed output by the motor 4 is converted into a low-speed, high-torque motion, which enables the system to drive the barrier rod more easily. Especially when dealing with a heavier or longer barrier rod, sufficient power can be provided to avoid stalling or losing speed when the barrier rod starts or stops.

[0109] Improving system stability: The speed reducer reduces the high-speed output of the motor 4 to a suitable working speed, making the operation of the entire barrier gate system more stable and reliable. Especially during the start and stop processes, the speed reduction effect can effectively reduce impact and vibration, improving the overall stability and service life of the system.

[0110] Precise control: Due to the lower output speed after deceleration, the system can control the lifting of the barrier rod at a more precise speed. This precise control is particularly important for barrier gate systems that need to be frequently opened and closed, and can ensure that each action of the barrier rod maintains consistency and accuracy.

[0111] Compact design: After the reducer 6 is introduced, the overall design of the gate mechanism of the present application solution remains compact through the arrangement of the reducer input shaft 61 and the output transmission shaft 62 of the reducer 6. The reducer 6 is cleverly arranged between the second surface and the motor 4, utilizing the vertical space, and is reasonably matched with the configuration of other components of the transmission mechanism, avoiding additional space occupation and maintaining the compact structure of the system.

[0112] In summary, in this embodiment, the reducer 6 enhances the torque output and operation stability of the system by converting the high-speed output of the motor 4 into low-speed and high-torque motion, and improves the operational reliability of the gate through precise control. This design not only ensures the ability of the system to handle heavier gate bars, but also maintains the compactness of the overall structure, so that the gate movement achieves a good balance in performance and structure.

[0113] Reference Figure 2 In some embodiments, the motor 4 provided in the embodiment of the utility model further includes a manual control device 7, which is connected to the input end of the motor 4 in a transmission manner, and is used to drive the output end of the motor 4 to drive the active shaft 51 to rotate, so that the driven shaft 3 rotates and drives the gate rod 400 to rotate;

[0114] In some embodiments, the driven rotating shaft 3, the driving rotating shaft 51, and the output transmission shaft 62 are all arranged horizontally.

[0115] In this embodiment, the manual control device 7 is connected to the input shaft of the motor 4 through transmission, so that the manual force applied from the outside can directly act on the input shaft of the motor, thereby driving the output shaft of the motor. This design enables the operator to directly control the gate bar to rise or fall through the manual control device in special circumstances (such as power outage or motor failure).

[0116] When the motor fails or the power is interrupted, the operator can apply external force through the manual control device 7. This external force is transmitted to the input shaft of the motor 4 through the manual control device 7.

[0117] The manual control device 7 converts the external force applied by the operator into rotational motion, and indirectly drives the output shaft of the motor to rotate through a transmission connection with the input shaft of the motor.

[0118] The output shaft of the motor 4 is connected to the driving shaft 51 through the reducer 6 or directly, thereby driving the driving shaft 51 to rotate.

[0119] The rotation of the active shaft 51 transmits the motion to the driven shaft 3 through the transmission mechanism 5 (including the active swing arm 52, the connecting rod 54 and the driven swing arm 53), and finally drives the gate rod 400 to rotate, thereby realizing the opening or closing of the gate.

[0120] The manual control device 7 provides a means to operate the barrier gate even when the electric system fails, enhancing the reliability of the system and its emergency operation capabilities. Especially in the event of a power outage or motor failure, the operator can still ensure the normal use of the barrier gate through manual operation.

[0121] This design ensures that the barrier gate can be controlled under any circumstances, avoiding potential safety hazards caused by system failure. For example, in an emergency, the operator can quickly manually open the barrier gate to evacuate vehicles or personnel.

[0122] The effect of the driven rotating shaft 3, the driving rotating shaft 51, and the output transmission shaft 62 all being horizontally arranged is as follows:

[0123] The horizontally arranged transmission shafts can make better use of the horizontal space of the barrier gate mechanism, reduce the occupation of vertical space, and are suitable for designs with limited internal height of the barrier gate. In addition, this layout can make the center of gravity of the system lower, thereby improving the overall stability.

[0124] The horizontally arranged transmission shafts make the transmission connection between the shafts more direct, reducing the efficiency loss caused by angle transmission. For a barrier gate system that needs to work frequently for a long time, this setting can improve the overall transmission efficiency and reduce mechanical wear.

[0125] In summary, the manual control device 7 provides an emergency operation solution for the barrier gate in case of power or motor failure, greatly improving the reliability and safety of the system. And the fact that the driven rotating shaft 3, the driving rotating shaft 51, and the output transmission shaft 62 are all horizontally arranged optimizes the structure and space utilization of the system, simplifies the maintenance work, and improves the transmission efficiency, making the entire barrier gate mechanism more efficient, compact, and easy to operate.

[0126] Referring to Figures 4 to 7 , in some embodiments, the driven swing arm 53 proposed in the embodiment of the present utility model includes a cylindrical structure 531, a driven arm 532, and a first hinge portion 533. The cylindrical structure 531 is hollow, a part of the driven rotating shaft 3 penetrates through the cylindrical structure 531, one end of the driven arm 532 is fixedly connected to the circumferential side of the cylindrical structure 531, and the first hinge portion 533 is provided at the other end of the driven arm 532. The first hinge portion 533 is used to rotatably connect to the second end of the connecting rod 54 through a hinge.

[0127] In this embodiment, the driven swing arm 53 realizes a stable and rotatable connection between the driven rotating shaft 3 and the connecting rod 54, so as to drive the driving rotating shaft 51 of the motor 4 to rotate, and transmit the output force of the rotational motion to the driven rotating shaft 3 through the connecting rod 54, thereby driving the movement of the brake rod. Specifically, the cylindrical structure 531 is sleeved on the driven rotating shaft 3, and the rotational motion is transmitted to the first hinge portion 533 through the driven arm 532, and is connected to the second end of the connecting rod 54 through a hinge, thereby realizing smooth transmission of the motion.

[0128] The working principle of the driven swing arm 53 in the solution of this application is as follows:

[0129] The cylindrical structure 531 of the driven swing arm 53 is a hollow design and is partially sleeved on the driven rotating shaft 3. In this way, the rotation of the driven rotating shaft 3 can be directly transmitted to the cylindrical structure 531, causing it to rotate accordingly.

[0130] The cylindrical structure 531 is connected to the driven arm 532 through its circumferential side. When the cylindrical structure 531 rotates with the driven rotating shaft 3, the driven arm 532 also moves accordingly. Since the design of the driven arm 532 can effectively transmit the rotational force of the cylindrical structure 531 to the hinge portion, this can ensure stable and efficient power transmission of the entire system.

[0131] The other end of the driven arm 532 is provided with a first hinge portion 533, and the hinge portion 533 is rotatably connected to the second end of the connecting rod 54 through a hinge. In this way, when the driven arm 532 moves, the hinge portion 533 will also rotate accordingly, thereby driving the connecting rod 54, and transmitting it to the driving rotating shaft 51 through the movement of the driving swing arm 52, and finally causing the brake rod to act.

[0132] The solution of this application realizes the following effects by setting the driven swing arm 53 with the above structure:

[0133] Through the partial sleeved connection between the cylindrical structure 531 and the driven rotating shaft 3, this design ensures that the rotation of the driven rotating shaft 3 can be smoothly transmitted to the driven arm 532. This connection method reduces the looseness or gaps that may occur during the mechanical transmission process, ensuring the reliability of the transmission.

[0134] The hollow design of the cylindrical structure 531 not only effectively utilizes the space, but also simplifies the design of the overall structure, making the entire swing arm system more compact. In addition, the stability and accuracy of the connecting components also greatly improve the durability of the system and reduce wear.

[0135] The design of the driven swing arm 53 can effectively transmit the rotational force of the driven rotating shaft 3 to the connecting rod 54 and the driving rotating shaft 51. Due to the tight connection between the components, the transmission efficiency is high, reducing energy loss and mechanical friction.

[0136] The first hinge part 533 is connected to the connecting rod 54 through a hinge, enabling the entire swing arm system to have a certain flexibility during operation and adapt to different movement angles and path requirements. In this way, not only is the adaptability of the barrier gate system improved, but the system is also more stable when facing external force interference.

[0137] In summary, through the design of the cylindrical structure 531, the driven arm 532, and the first hinge part 533 of the driven swing arm 53, an efficient and stable motion transmission between the driven rotating shaft 3 and the connecting rod 54 is achieved. This design improves the compactness and transmission efficiency of the system, while ensuring stability and durability during the transmission process. Through the optimization of this structure, the barrier gate system can drive the gate rod more smoothly and efficiently during operation, achieving an effective control effect.

[0138] Refer to Figure 7 , in some embodiments, the driven swing arm 53 proposed in the embodiment of the present utility model further includes a balance arm 534. The balance arm 534 is inclined at an obtuse angle with respect to the driven arm 532. The first end of the balance arm 534 is fixedly connected to the circumference of the cylindrical structure 531, and the second end of the balance arm 534 is used for elastic connection to the machine case.

[0139] In this embodiment, by forming an inclined structure with an obtuse angle with the driven arm 532, the balance arm 534 can provide a reverse balancing moment when the driven arm 532 is stressed. At the same time, the second end of the balance arm 534 is connected to the machine case through an elastic element (such as a spring or a shock absorber), which can absorb and relieve the vibration and impact generated by mechanical transmission. This design not only ensures that the driven swing arm 53 can maintain balance during operation, avoiding tilting or instability caused by unilateral stress, but also effectively balances the gravity of the gate rod of the barrier gate, thereby reducing the burden on the motor 4 and ensuring that the barrier gate is more lightweight when opening and closing. This can extend the service life of the equipment and reduce the failure rate.

[0140] The working principle of the balance arm proposed in the solution of this application is as follows:

[0141] During the operation of the barrier gate, the driven arm 532 transmits the rotational force of the driven rotating shaft 3 to the connecting rod 54. Due to the force transmission and swing, one side of the driven arm may be subjected to greater stress, resulting in tilting or imbalance of the system. The balance arm 534, by being arranged at an obtuse angle with the driven arm 532, can generate a reverse moment to offset part of the unbalanced force and maintain the balance state of the driven swing arm 53.

[0142] The second end of the balance arm 534 is connected to the machine case through an elastic element. When the driven swing arm 53 is working, the elastic element can absorb the vibration and impact generated during the transmission process, reduce the influence of these external forces on the driven swing arm 53, thereby improving the smoothness and durability of the system.

[0143] Since the balance arm 534 is obliquely connected to the driven arm 532 at an obtuse angle, the entire system can dynamically adjust the balance state according to the actual force conditions during operation. The presence of the elastic element enables the balance arm to make fine adjustments as the system moves, always maintaining the optimal balance state.

[0144] By providing the driven swing arm 53 of the balance arm 534 with the above structure, the present application achieves the following effects:

[0145] Improve system stability: The balance arm 534, through its inclined setting with the driven arm 532, effectively cancels out the unbalanced torque that may be generated during the operation of the driven swing arm 53. Especially during long-term and high-frequency operation, this design can significantly improve the stability of the barrier gate system and avoid failures or wear caused by mechanical offset.

[0146] Enhanced shock absorption and anti-vibration performance: The elastic connection between the balance arm 534 and the chassis can effectively absorb the vibrations and impacts generated during mechanical transmission, reducing the influence of these external forces on the system. This shock absorption effect not only improves the operating smoothness of the system but also extends the service life of key components.

[0147] Maintain precise transmission control: Through the action of the balance arm, the system can maintain a high degree of balance and stability during operation, thereby ensuring that the transmission mechanism can transmit power to the barrier rod in a precise manner. This is crucial for the precise control and efficient operation of the barrier gate system, especially in application scenarios with high requirements, which can significantly improve the overall performance of the system.

[0148] Extend the system life: Since the balance arm 534 can effectively absorb shocks and vibrations, this design reduces the wear of key components and extends the service life of the barrier gate system. Reducing unnecessary vibrations and stress concentrations enables the system to operate reliably for a longer time.

[0149] In summary, the balance arm 534 in this embodiment, through its obtuse-angle inclined setting with the driven arm 532 and elastic connection with the chassis, effectively improves the stability, balance, and anti-vibration performance of the driven swing arm 53. This design not only enhances the operating smoothness and control accuracy of the barrier gate system but also extends the service life of the system.

[0150] Refer to Figures 4 to 6 , in some embodiments, the barrier gate core proposed in the embodiment of the present utility model further includes a balance mechanism 8, and the balance mechanism 8 includes:

[0151] A first connecting member 81, one end of the first connecting member 81 is connected to the second end of the balance arm 534;

[0152] The second connecting member 82 is spaced on one side of the first connecting member 81, and one end of the second connecting member 82 is connected to the chassis;

[0153] An elastic member 83, the first end of the elastic member 83 is connected to the other end of the first connecting member 81, and the second end of the elastic member 83 is connected to the other end of the second connecting member 82.

[0154] In this embodiment, the balance mechanism 8 adjusts the force-bearing state of the balance arm 534 through the elastic force of the elastic member 83, so as to maintain the balance of the driven swing arm 53. The first connecting member 81 connects the balance arm 534 and the elastic member 83, while the second connecting member 82 fixes the elastic member to the chassis. The presence of the elastic member 83 enables the entire balance mechanism 8 system to be adjusted in real time according to the load and motion state, so as to maintain balance and absorb shocks.

[0155] When the barrier gate system is running, the movement of the driven swing arm 53 is transmitted to the balance mechanism 8 through the balance arm 534. The second end of the balance arm 534 is connected to the first connecting member 81, and the other end of the first connecting member 81 is connected to the elastic member 83. This enables when the balance arm 534 is stressed, the force is transmitted to the elastic member 83 through the first connecting member 81.

[0156] The first end of the elastic member 83 is connected to the other end of the first connecting member 81, and the second end is connected to the other end of the second connecting member 82. The second connecting member 82 is fixed to the chassis, and this fixing point provides a stable support for the system. The elastic member 83 is stretched or compressed according to the force on the balance arm 534, generating a corresponding reaction force. This reaction force can balance the stress in the system, making the entire driven swing arm 53 keep stable and controlled during movement.

[0157] Due to the elastic adjustment of the elastic member 83, the system can dynamically adjust the balance state according to the actual operation situation. This adaptive adjustment mechanism ensures that the driven swing arm 53 can still maintain balance and stability under different loads and motion conditions.

[0158] Through the adjustment of the elastic member 83 to the force, the balance mechanism 8 can effectively absorb and relieve the shocks and vibrations generated during the movement process. This not only improves the operation stability of the system, but also reduces the mechanical wear caused by vibrations and shocks.

[0159] In the face of different load conditions, the elastic adjustment of the balance mechanism 8 ensures the reliability and consistency of the barrier gate system. This reliability is particularly important for the barrier gate system that needs to be operated frequently, and can ensure that each opening and closing action can be accurately executed.

[0160] In summary, through the collaborative action of the first connection member 81, the second connection member 82, and the elastic member 83, the balance mechanism 8 in this embodiment achieves dynamic balance adjustment and shock absorption of the driven swing arm 53. This design greatly enhances the stability and reliability of the gate system, and at the same time extends the service life of the system, which is an effective optimization of the balance control of the gate movement mechanism.

[0161] Referring Figures 4 to 6 , in some embodiments, the first connection member 81 proposed in the embodiment of the present utility model includes:

[0162] A first connection portion 811, a second hinge portion 535 is formed at the second end of the balance arm 534, and one end of the first connection portion 811 is hinged to the second hinge portion 535;

[0163] A first transfer portion 812, located between the first connection portion 811 and the elastic member 83, and one end of the first transfer portion 812 is connected to the first end of the elastic member 83;

[0164] A first distance adjustment member 813, one end of the first distance adjustment member 813 is connected to the other end of the first connection portion 811, and the other end of the first distance adjustment member 813 is connected to the other end of the first transfer portion 812. The first distance adjustment member 813 is used to move the first transfer portion 812 in the direction towards the first connection portion 811 to stretch the elastic member 83, and is also used to move the first transfer portion 812 in the direction away from the first connection portion 811 to relax the elastic member 83;

[0165] In some embodiments, the second connection member 82 includes:

[0166] A second connection portion 821, located between the elastic member 83 and the chassis, and one end of the second connection portion 821 is connected to the second end of the elastic member 83;

[0167] A second distance adjustment member 822, one end of the second distance adjustment member 822 is connected to the other end of the second connection portion 821, and the other end of the second distance adjustment member 822 is connected to the chassis. The second distance adjustment member 822 is used to move the second connection portion 821 in the direction towards the chassis to stretch the elastic member 83, and is also used to move the second connection portion 821 in the direction away from the chassis to relax the elastic member 83.

[0168] In this embodiment, the first connection member 81 and the second connection member 82 adjust the tension of the elastic member 83 through a distance adjustment mechanism, thereby precisely controlling the balance state of the system.

[0169] The design of the first connecting member 81 can adjust the tension of the elastic member 83 through the distance adjustment mechanism. The first connecting member 81 is composed of a first connecting portion 811, a first adapter portion 812 and a first distance adjustment member 813. The first connecting portion 811 is connected to the second hinge portion 535 of the balance arm 534 by an articulated manner to ensure the flexibility and motion transmission of the system. The first adapter portion 812 is used to connect the elastic member 83, and the tension or relaxation state of the elastic member 83 is changed by adjusting the first distance adjustment member 813.

[0170] Tension adjustment: One end of the first distance adjusting member 813 is connected to the other end of the first connecting portion 811, and the other end of the first distance adjusting member 813 is connected to the first adapter portion 812. By adjusting the first distance adjusting member 813, the first adapter portion 812 can be moved toward or away from the first connecting portion 811, thereby stretching or relaxing the elastic member 83 relative to the chassis. Stretching the elastic member 83 increases the balancing moment of the system, while relaxing it reduces the balancing moment.

[0171] The second connecting member 82 is similar to the first connecting member 81, and realizes the tension adjustment of the elastic member 83 through the distance adjustment mechanism. It is composed of a second connecting portion 821 and a second distance adjustment member 822, the second connecting portion 821 is used to connect the elastic member 83 to the chassis, and the second distance adjustment member 822 is used to control the tension of the elastic member 83 by adjusting the position of the second connecting portion 821.

[0172] The second connection portion 821 is located between the elastic member 83 and the chassis, and is used to connect the second end of the elastic member 83. The second connection portion 821 is fixed to the chassis, providing a stable supporting point.

[0173] One end of the second distance adjusting member 822 is connected to the other end of the second connecting portion 821, and the other end of the second distance adjusting member 822 is fixed to the chassis or other fixed points. By adjusting the second distance adjusting member 822, the second connecting portion 821 can be moved toward or away from the chassis, thereby adjusting the stretching or relaxation state of the elastic member 83, thereby controlling the balance of the system.

[0174] It should be noted that, the first distance adjusting member 813 and the second distance adjusting member 822 can be provided alone or both in the system of the balancing mechanism 8 .

[0175] Through the distance adjustment mechanism of the first connecting member 81 and the second connecting member 82, the system can accurately adjust the tension of the elastic member 83. This precise adjustment can effectively control the force state of the balance arm 534, thereby ensuring that the system maintains an optimal balance state under different operating conditions.

[0176] Tension adjustment can not only regulate the balance state of the balance arm 534, but also absorb and relieve the vibrations and impacts generated during the operation of the system. This mechanism improves the stability and operational reliability of the system, especially when dealing with frequent operations or complex environments, and the effect is particularly significant.

[0177] The adjustment functions of the first connecting member 81 and the second connecting member 82 enable the system to be adjusted according to the actual application scenarios, adapting to different loads and operating conditions. This flexibility enhances the versatility and adaptability of the system.

[0178] In summary, in this embodiment, the first connecting member 81 and the second connecting member 82 achieve precise control of the balance state of the barrier gate system by adjusting the tension of the elastic member 83. This design not only enhances the stability and durability of the system, but also provides flexible adaptability, enabling the barrier gate core to maintain a reliable operating state in different application environments.

[0179] Refer to Figures 4 to 6 , in some embodiments, the elastic member 83 proposed in the embodiment of the present utility model includes:

[0180] A spring body 830, the interior of the spring body 830 is hollow;

[0181] A first limiting portion 831, the first limiting portion 831 is connected to one end of the spring body 830 and has a first opening communicating with the interior of the spring body 830;

[0182] A first connecting member 832, one end of the first connecting member 832 is provided with a first spherical portion 8320 accommodated in the interior of the spring body 830, and the other end of the first connecting member 832 passes through the first opening and is connected to the first connecting member 81;

[0183] A second limiting portion 833, the second limiting portion 833 is connected to the other end of the spring body 830 and has a second opening communicating with the interior of the spring body 830;

[0184] A second connecting member 834, one end of the second connecting member 834 is provided with a second spherical portion 8340 accommodated in the interior of the spring body 830, and the other end of the second connecting member 834 passes through the second opening and is connected to the second connecting member 82;

[0185] Wherein, the first limiting portion 831 is used to limit the first spherical portion 8320 within the spring body 830, and the second limiting portion 833 is used to limit the second spherical portion 8340 within the spring body 830.

[0186] In this embodiment, the elastic member 83 forms an elastic system with good buffering and adjustment functions by introducing a spring body 830, a first limiting portion 831, a first connecting member 832, a second limiting portion 833, and a second connecting member 834. This design effectively integrates force transmission and absorption in a compact system, ensuring the smoothness and durability of the barrier gate movement during operation. The following elaborates in detail the principle of action, the process of action, and the effects of the elastic member 83.

[0187] The elastic member 83 mainly provides an elastic force through the spring body 830 to achieve the balance and vibration absorption of the balance arm 534 and the entire barrier gate system. The first connecting member 832 and the second connecting member 834 are connected to the inside of the spring body 830 through their respective spherical portions (8320 and 8340), and the limiting portions (831 and 833) limit these spherical portions within the spring body, enabling the spring to effectively transmit force and absorb impacts.

[0188] One end of the first connecting member 832 is provided with a first spherical portion 8320 having a spherical structure, and the first spherical portion 8320 is accommodated inside the spring body 830. Through the first limiting portion 831, the first spherical portion 8320 is restricted within the spring body 830. Similarly, one end of the second connecting member 834 is provided with a second spherical portion 8340, which is accommodated inside the spring body 830 and its position is restricted by the second limiting portion 833.

[0189] The first connecting member 832 and the second connecting member 834 are equivalent to joints that can float relative to the spring body 830.

[0190] When the spring body 830 is stretched or compressed by the connecting members, corresponding rebound forces or resistance forces are generated. This elastic action ensures that the system can buffer when subjected to external forces, reducing the impact force directly transmitted to the balance arm 534 or other connecting members.

[0191] By adjusting the positions and the applied forces of the first connecting member 832 and the second connecting member 834, the stretching or compression state of the spring body 830 can be changed, thereby adjusting the overall mechanical properties of the elastic member 83. This adjustment process can dynamically adapt to the operating state of the system, ensuring that the barrier gate movement remains balanced and stable under different load conditions.

[0192] In summary, the above structural design of the elastic member 83 in this embodiment realizes the mechanical adjustment and impact absorption of the barrier gate system. The cooperation between the spring body 830 and the spherical portions of the connecting members provides good buffering performance and flexibility in force transmission. This design improves the smoothness and durability of the system, enabling the barrier gate movement to maintain efficient and stable operation under various operating conditions.
