Description

Technical Field

[0001] This utility model relates to the field of transportation facilities technology, and more specifically, to a door control transmission mechanism device. Background Technology

[0002] As a common infrastructure component, the gate arm is a key part of access control equipment such as road barriers and gate gates. Its core function is to achieve orderly management, access control, and security protection of vehicle passage by physically blocking and allowing passage at road or passage entrances. It is widely used in parking lots and other places that require vehicle passage management. The gate arm gate control transmission mechanism transmits the rotational power generated by the motor and converts it into the reciprocating rotation of the gate arm at a specific angle, thereby realizing its raising and lowering function. The performance of this transmission mechanism directly determines the reliability, stability, security, and service life of the entire road barrier device.

[0003] Most existing gate control transmission mechanisms are based on traditional worm gear drives. When lifting the gate arm, the motor needs to output a huge torque to overcome the gate arm's own weight and the friction of the device, resulting in high instantaneous current and high energy consumption. Long-term operation can easily lead to overheating and shorten the motor's lifespan. Simultaneously, the huge force is concentrated on the meshing tooth surface of the worm gear, accelerating tooth wear, affecting transmission accuracy, and even causing failure. Furthermore, existing transmission mechanisms are often designed for gate arms of specific lengths and weights. When it is necessary to replace gate arms of different specifications, existing mechanisms often lack simple torque adjustment methods, which may require replacing the entire motor or transmission assembly, or requiring professional personnel to perform complex adjustments using specialized tools, which is time-consuming, labor-intensive, and lacks versatility and flexibility. Therefore, we propose an improved gate control transmission mechanism. Summary of the Invention

[0004] The purpose of this utility model is to address the problem that most existing gate control transmission mechanisms are based on traditional worm gear drives. When lifting the gate arm, the motor needs to output a huge torque to overcome the weight of the gate arm and the friction of the device, resulting in a large instantaneous current and high energy consumption of the motor. Long-term operation can easily lead to overheating and shorten the motor's lifespan. At the same time, the huge force is also concentrated on the meshing tooth surface of the worm gear and worm, which aggravates tooth surface wear, affects transmission accuracy, and may even lead to failure. Furthermore, existing transmission mechanisms are often designed for gate arms of specific lengths and weights. When it is necessary to replace gate arms of different specifications, existing mechanisms often lack simple torque adjustment methods.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: To address the shortcomings of existing gate control transmission mechanisms, which are mostly based on traditional worm gear drives, where the motor needs to output enormous torque to overcome the gate's weight and friction during gate lifting, resulting in high instantaneous current, high energy consumption, and overheating during long-term operation, thus shortening motor lifespan, and the concentrated force on the meshing teeth of the worm gear exacerbates tooth wear, affecting transmission accuracy and even causing failure, and where existing transmission mechanisms are often designed for gates of specific lengths and weights, lacking convenient torque adjustment methods when changing to different gate specifications, potentially requiring replacement of the entire motor or transmission assembly, or complex adjustments by professionals using specialized tools—a time-consuming, labor-intensive process with insufficient versatility and flexibility, this application proposes a transmission component utilizing a worm gear... The worm gear mechanism enables smooth, shock-free rotation of the gate arm. Its inherent self-locking characteristic ensures reliable locking of the gate arm in any position, greatly enhancing the safety and stability of the device. The protection component provides auxiliary torque to the worm gear using spring tension when the gate arm is raised, and provides controllable damping force through the elastic resistance of the spring when the gate arm is lowered. This allows the gate arm to descend smoothly and slowly, effectively reducing the instantaneous load on the motor and overall energy consumption. It also significantly reduces wear on the worm gear and worm meshing transmission, extending the service life of the entire device. Furthermore, the torque requirements of different gate arms can be precisely matched by changing the lever arm, and the adjustment method is convenient; operators can adjust it manually without tools, saving time and effort and greatly improving the efficiency of on-site installation and maintenance.

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0020] As described in the background section, most existing gate arm control transmission mechanisms are based on traditional worm gear drives. When lifting the gate arm, the motor needs to output a huge torque to overcome the gate arm's own weight and the device's friction, resulting in a large instantaneous current and high energy consumption. Long-term operation can easily lead to overheating and shorten the motor's lifespan. At the same time, the huge force is also concentrated on the meshing tooth surface of the worm gear and worm, which aggravates tooth surface wear, affects transmission accuracy, and may even lead to failure. Furthermore, existing transmission mechanisms are often designed for gate arms of specific lengths and weights. When it is necessary to replace gate arms of different specifications, existing mechanisms often lack simple torque adjustment methods. It may be necessary to replace the entire motor or transmission assembly, or require professional personnel to use special tools for complex debugging, which is time-consuming, labor-intensive, and lacks versatility and flexibility.

[0021] To solve this technical problem, this utility model provides a gate control transmission mechanism device, which is applied to the gate arm drive mechanism for controlling vehicle entry and exit.

[0022] For details, please refer to Figures 1-7 The gate control transmission mechanism specifically includes: The enclosure 1 is used for protection and the gate 2 is used to control the entry and exit of vehicles. The gate 2 is rotatably connected to the upper part of one side of the enclosure 1. A first housing 3 is fixedly connected to the upper part of the inner wall of the enclosure 1. A second housing 4 is fixedly connected to one side of the first housing 3. A transmission component 5 for driving the gate 2 to rotate is installed inside the first housing 3. A protective component 6 for the auxiliary transmission component 5 is installed on one side of the second housing 4.

[0023] The gate control transmission mechanism provided by this utility model enables the smooth and shock-free rotation of the gate arm 2 through the transmission component 5. Its inherent self-locking characteristic ensures that the gate arm 2 can be reliably locked in any position, greatly improving the safety and stability of the device. The protection component 6 provides auxiliary torque to the transmission component 5 when the gate arm 2 is raised, and provides controllable damping force through the elastic resistance of the protection component 6 when the gate arm 2 is lowered, allowing the gate arm 2 to descend smoothly and slowly. This effectively reduces the instantaneous load and overall energy consumption of the transmission component 5, while significantly reducing wear on the transmission component 5, thereby extending the service life of the entire device. Furthermore, the torque requirements of different gate arms 2 can be precisely matched by changing the lever arm, and the adjustment method is convenient; operators can adjust it manually without tools, saving time and effort and greatly improving the efficiency of on-site installation and maintenance.

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] Example 1, please refer to Figures 1-7 A gate control transmission mechanism includes a protective housing 1 and a gate arm 2 for controlling vehicle entry and exit. The gate arm 2 is rotatably connected to the upper side of the housing 1. A first housing 3 is fixedly connected to the upper side of the inner wall of the housing 1. A second housing 4 is fixedly connected to one side of the first housing 3. A transmission component 5 for driving the gate arm 2 to rotate is installed inside the first housing 3. A protective component 6 for the auxiliary transmission component 5 is installed on one side of the second housing 4. When the gate arm 2 needs to be raised or lowered, a motor 503 is started. The output shaft of the motor 503 directly drives the worm gear 502 to rotate. The worm gear 502 meshes with the worm wheel 501, and the rotational motion of the worm gear 502 is converted into the rotational motion of the worm wheel 501. The central output shaft of the worm wheel 501 drives the gate arm 2 to perform the action of raising or lowering.

[0028] Furthermore, such as Figures 1-3 As shown, the transmission assembly 5 includes a worm gear 501, a worm 502, and a motor 503. The worm gear 501 is rotatably connected between the first housing 3 and the second housing 4. The worm 502 is fixedly connected to the inner wall of the first housing 3. The motor 503 is fixedly installed on one side of the lower end of the first housing 3. The worm gear 501 and the worm 502 mesh with each other. The output end of the motor 503 passes through the first housing 3 and is fixedly connected to the center of one side of the worm gear 501. The output end of the worm gear 501 passes through the first housing 3 and the housing 1 and is fixedly connected to one side of the gate arm 2. The meshing transmission of the worm gear 501 and the worm 502 gives the entire device a reliable self-locking characteristic, ensuring that the gate arm 2 can be locked instantly at any required position, greatly improving the safety and stability of the equipment. At the same time, this transmission structure is stable, has low noise, and high load-bearing capacity, and can efficiently and accurately convert the power of the motor 503 into the high torque rotation of the gate arm 2.

[0029] Example 2 further optimizes the door control transmission mechanism device provided in Example 1, specifically, as follows: Figures 1-5As shown, the protection component 6 includes a first connecting rod 601, which is rotatably connected to the center of the second housing 4 on the side away from the first housing 3. A second connecting rod 602 is rotatably connected to the side of the first connecting rod 601 away from the first housing 3. A rotating plate 603 is rotatably connected to the side of the second connecting rod 602 near the first housing 3. The rotating plate 603 is rotatably connected to the upper part of the side of the first housing 3. The output end of the worm gear 501 passes through the second housing 4 and is fixedly connected to the side of the first connecting rod 601. When the gate arm 2 is driven by the motor 503 to rotate downward from a vertical position, it will drive the first connecting rod 601 to rotate through the output shaft of the worm gear 501. The first connecting rod 601 drives the second connecting rod 602 to rotate. The second connecting rod 602 drives the rotating plate 603 to rotate on the first housing 3. This causes the lever arm on one side of the rotating plate 603 to rotate and stretch the first spring 607. During this process, the first spring 607 is stretched, and part of the gravitational potential energy of the gate arm 2 is converted into the elastic potential energy of the first spring 607 and stored. At the same time, the tensile resistance generated by the first spring 607 provides a continuous damping force for the falling process, allowing the gate arm 2 to fall smoothly and slowly, effectively avoiding rigid impact, noise, and recoil damage to the transmission device when reaching the bottom. When the motor 503 needs to drive the gate arm 2 to rise from the horizontal position, the output end of the motor 503 rotates in the opposite direction, and the stretched first spring 607 returns to its original state. Similarly, the first spring 607... The pull force generated by spring 7 will apply an auxiliary pull force to the first connecting rod 601, which helps the motor 503 drive the worm gear 501 to rotate, significantly reducing the load and energy consumption of the motor 503. It also reduces the transmission pressure on the meshing tooth surfaces of the worm gear 501 and worm 502, thereby reducing wear and extending equipment life. Furthermore, the connecting plate 605 can be inserted into the slot 612 of the rotating disk 604 at different positions. By changing the distance between the connection point and the rotation center of the rotating disk 603, the lever arm length of the first spring 607's pull force on the rotating disk 603 is changed. The further out the connection point, the longer the lever arm, and the greater the auxiliary torque generated, suitable for heavier and longer gate arms 2. When adjusting the lever arm, the connecting plate 605 is inserted into the selected rotating disk 604. When the slot 612 is engaged, the front end of the connecting plate 605 will press against the wedge-shaped locking block 616. The wedge-shaped locking block 616 will decompose the thrust, and the second spring 614 will contract under the thrust. When the slot 610 is aligned with the slot 610, the elastic force of the second spring 614 will push the wedge-shaped locking block 616 into the slot 610, achieving initial pre-fixing. Subsequently, rotating the knob 621 will drive the bidirectional screw 618 to rotate, causing the two sliding plates 619 to move closer to each other, thereby pushing the limiting blocks 620 on them to insert into the limiting grooves 611 on both sides of the connecting plate 605, ensuring the absolute stability of the connecting plate 605 during operation and preventing it from loosening. The adjustment method is convenient, and the operator can complete the adjustment by hand without tools, saving time and effort and greatly improving the efficiency of on-site installation and maintenance.

[0030] Furthermore, such as Figure 3 and Figure 4 As shown, a plurality of rotating disks 604 are rotatably connected to the side of the rotating plate 603 away from the first housing 3. A connecting plate 605 is installed inside one of the rotating disks 604. A first connecting seat 606 is fixedly connected to the lower end of the connecting plate 605. A plurality of first springs 607 are fixedly connected to the lower end of the first connecting seat 606. The lower ends of the plurality of first springs 607 are jointly fixedly connected to a second connecting seat 608. A fixing seat 609 is fixedly connected to one side of the bottom of the inner wall of the housing 1. The second connecting seat 608 is hinged to the middle of the fixing seat 609. The plurality of rotating disks 604 provide a plurality of optional installation positions. By connecting the plate Installed on rotating disks 604 at different positions, 605 enables stepless adjustment of the lever arm length of the first spring 607, thereby precisely matching the auxiliary torque requirements of gate arms 2 of different lengths and weights, enhancing the product's adaptability. The first spring 607 is stretched and stores energy when the gate arm 2 falls, converting gravitational potential energy into elastic potential energy, and releases energy to assist when the gate arm 2 rises, forming an efficient energy cycle that significantly saves energy and protects the motor 503. At the same time, the damping provided by the stretching of the first spring 607 ensures that the gate arm 2 descends smoothly and slowly, effectively eliminating impact noise and ensuring smooth and efficient operation of the mechanism.

[0031] Furthermore, such as Figures 1-5 As shown, a slot 610 is provided on the upper side of one side of the connecting plate 605, and limit slots 611 are provided on both sides of the connecting plate 605. Limiting components for fixing the connecting plate 605 are installed in the multiple rotating disks 604. Each limiting component includes a slot 612, which is located on the side wall of the rotating disk 604. The connecting plate 605 and the slot 612 engage. A sliding groove 613 is provided on one side of the inner wall of the slot 612. A second spring 614 is fixedly connected to the inner wall of the sliding groove 613. A moving plate 615 is fixedly connected to the front end of the second spring 614. The moving plate 615 is slidably connected to the inner wall of the sliding groove 613, and is located away from the second spring. One end of 614 is fixedly connected to a wedge-shaped locking block 616. The wedge-shaped locking block 616 and the slot 610 engage in a locking action. When the connecting plate 605 is inserted into the slot 612 of the rotating disk 604, the wedge-shaped locking block 616 can automatically slide into the slot 610 on the connecting plate 605 under the pre-pressure of the second spring 614, thereby completing the initial positioning and pre-fixation of the connecting plate 605, effectively preventing it from loosening. This makes the installation process tool-free and extremely simple to operate, greatly improving the adjustment efficiency. At the same time, this initial locking structure provides a stable foundation for the subsequent final locking, ensuring the accuracy of the position of the connecting plate 605 throughout the locking process.

[0032] Furthermore, such as Figure 5 and Figure 6As shown, a working cavity 617 is provided inside the rotating disk 604. A bidirectional screw 618 is rotatably connected to the inner wall of the working cavity 617. Two symmetrically arranged sliding plates 619 are slidably connected to the inner wall of the working cavity 617. The bidirectional screw 618 passes through the two sliding plates 619, and the two sliding plates 619 are externally threaded to the bidirectional screw 618. Limiting blocks 620 are fixedly connected to the side of each sliding plate 619 near the slot 612. The two limiting blocks 620 pass through the inner wall of the working cavity 617, and the two limiting blocks 620 respectively engage with two limiting slots 611. A knob 621 is rotatably connected to the outer wall of the rotating disk 604. The output end of the knob 621 passes through the rotating disk 604, and the output end of the knob 621 is fixedly connected to one end of the bidirectional screw 618. By rotating the knob 621... The bidirectional screw 618 is driven to rotate, which can synchronously control the two sliding plates 619 to move in opposite directions, thereby precisely driving the two limit blocks 620 to insert or withdraw from the limit grooves 611 on both sides of the connecting plate 605. This symmetrical mechanical locking method eliminates the possibility of loosening of the connecting plate 605 through surface contact pressure, ensuring the absolute reliability of power transmission. Moreover, the operation can be completed by simply turning the knob 621 by hand, saving time and effort, requiring no tools, and greatly improving the efficiency of installation and debugging.

[0033] Example 3 further optimizes the door control transmission mechanism device provided in Example 1, specifically, as follows: Figure 1 and Figure 2 As shown, a control panel 7 is fixedly installed on the inner wall of the housing 1. Two pressure sensors 8 are fixedly installed at the end of the second housing 4 away from the first housing 3. The control panel 7, as the central control unit, realizes centralized management and precise control of the gate arm 2 raising and lowering, the operating parameters of the motor 503, and the system status, which greatly improves the convenience of operation and the expandability of functions. The two pressure sensors 8 installed on the second housing 4 can monitor the pressure changes in the transmission process in real time, providing the system with key overload protection and fault diagnosis capabilities. Once abnormal resistance is detected, a signal can be immediately fed back to the control panel 7 and trigger protection actions such as stop or reverse, effectively preventing the motor 503 from burning out and the mechanical structure from being damaged, thus constructing a safe and reliable active protection system.

[0034] It is worth noting that both the control panel 7 and the pressure sensor 8 are existing technologies. The control panel 7 typically consists of a microprocessor, a power circuit, a signal interface, and an operating interface. Its working principle is to receive external commands such as remote control and button signals or sensor feedback signals, and after internal logic processing, drive the motor 503 to perform predetermined actions. The pressure sensor 8 works based on the principle of piezoresistive or piezoelectric effect, converting the mechanical pressure on its sensing surface into an electrical signal and transmitting it to the control panel 7. The two work together to form a control system, realizing precise control of the start, stop, and direction of the motor 503, as well as overload protection functions, which will not be elaborated here.

[0035] Furthermore, such as Figure 5 and Figure 6 As shown, both the slot 612 and the inner wall of the limiting block 620 are provided with anti-slip pads. The anti-slip pads are made of soft rubber. By providing anti-slip pads of soft rubber on the inner walls of the slot 612 and the limiting block 620, the static friction between the contact surface and the connecting plate 605 is effectively increased, preventing slight displacement or sliding during operation and ensuring absolute stability of the connection.

[0036] The door control transmission mechanism device provided by this utility model is used as follows: When the gate arm 2 needs to be raised or lowered, the motor 503 starts, and the output shaft of the motor 503 directly drives the worm 502 to rotate. The worm 502 meshes with the worm wheel 501, and the rotational motion of the worm 502 is converted into the rotational motion of the worm wheel 501. The central output shaft of the worm wheel 501 drives the gate arm 2 to perform the action of raising or lowering. When the gate arm 2 is driven by the motor 503 to rotate downward from the vertical position, it will drive the first connecting rod 601 to rotate through the output shaft of the worm gear 501. The first connecting rod 601 drives the second connecting rod 602 to rotate, and the second connecting rod 602 drives the rotating plate 603 to rotate on the first housing 3. This causes the lever arm on one side of the rotating plate 603 to rotate and stretch the first spring 607. During this process, the first spring 607 is stretched, and part of the gravitational potential energy of the gate arm 2 is converted into the elastic potential energy of the first spring 607 and stored. At the same time, the tensile resistance generated by the first spring 607 provides a continuous damping force for the falling process, so that the gate arm 2 can fall smoothly and slowly, effectively avoiding rigid impact, noise and recoil damage to the transmission device when it reaches the bottom. When motor 503 needs to drive the brake lever 2 to rise from the horizontal position, the output end of motor 503 rotates in the opposite direction, and the stretched first spring 607 returns to its original state. Similarly, the retraction force generated by the first spring 607 will apply the auxiliary force to the first connecting rod 601, which can help motor 503 drive worm gear 501 to rotate. This significantly reduces the load and energy consumption of motor 503, and at the same time reduces the transmission pressure on the meshing tooth surface of worm gear 501 and worm 502, thereby reducing wear and extending the equipment life. Furthermore, the connecting plate 605 can be inserted into the slot 612 of the rotating disk 604 at different positions. By changing the distance between the connection point and the rotation center of the rotating disk 603, the lever arm length of the first spring 607's tension on the rotating disk 603 is changed. The further out the connection point, the longer the lever arm, and the greater the auxiliary torque generated, which is suitable for heavier and longer gate arms 2. When adjusting the lever arm, when the connecting plate 605 is inserted into the selected slot 612 of the rotating disk 604, the front end of the connecting plate 605 will press against the wedge-shaped locking block 616. The wedge-shaped locking block 616 decomposes the thrust, and the second spring 614 is compressed by the thrust. When the slot 610 is aligned with the slot 610, the elastic force of the second spring 614 will push the wedge-shaped block 616 into the slot 610, achieving initial pre-fixation. Subsequently, rotating the knob 621 drives the bidirectional screw 618 to rotate, causing the two sliding plates 619 to move closer to each other, thereby pushing the limiting block 620 on it to insert into the limiting grooves 611 on both sides of the connecting plate 605, ensuring the absolute stability of the connecting plate 605 during operation and preventing it from loosening.
