Description

Technical Field

[0001] This utility model relates to the field of electric gate technology, specifically to a motor drive structure suitable for small gates. Background Technology

[0002] Traditional large-scale electric gates with hinged doors, due to the large span and heavy weight of each door panel, typically employ large vertical motors in their drive structure, with the motor's output shaft aligned with the door hinge. In this design, the driving spur gear fixed to the motor's output shaft and the driven spur gear fixed to the door hinge maintain coaxiality and tight meshing, ensuring that the motor's torque is transmitted to the door hinge's rotation without loss. This structure performs well in large gates, meeting their torque and stability requirements. However, with the improvement of people's living standards, electric gates, due to their convenience, are gradually becoming the preferred equipment for medium and small-sized entrances and passageways.

[0003] In existing technologies, small electric gates, due to their small span, are typically not very heavy; many are even now made of aluminum alloy, making them even lighter. However, continuing to use large vertical motors for drive not only wastes costs and resources but also negatively impacts the overall aesthetics of the small electric gate due to the motor's large vertical dimensions. For example, if the motor is installed at the top of the gatepost, its abrupt shape will make the gatepost appear significantly taller, creating an uncoordinated look; if installed at the bottom, it poses risks of collision, water damage, and electrical leakage, resulting in significant safety hazards. Furthermore, small electric gates are often installed at the entrances and exits of passageways. If the vertical motor is installed at the top of the gatepost and its height exceeds that of the gate panel, the gate panel must be made shorter, significantly affecting the convenience of passage. More importantly, small electric gates are mainly installed at medium and small entrances and exits with high pedestrian traffic, opening and closing frequency extremely frequently, and used by a diverse range of people. In practical use, it has been found that many people passing through the entrances and exits may be in a hurry or unaware that this is an electric gate, and will directly and quickly push the gate open to pass through. For the motor drive structure where the vertical motor and the spur gear set are coaxial and tightly meshed, this manual pushing action will cause the driven spur gear fixed to the gate shaft to force an excessive speed action on the driving spur gear fixed to the motor output shaft, which is prone to "tooth sweeping" phenomenon, thereby causing damage and failure of the motor drive structure of the small gate. Utility Model Content

[0004] The purpose of this invention is to provide a motor drive structure suitable for small gates, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a motor drive structure suitable for small gates, comprising: a gate leaf, one side of which is hinged to one side of a supporting gate panel via large hinges at both the upper and lower ends; the other side of which is abutted against a limiting post; and the other side of the supporting gate panel is fixedly connected to a fixing post.

[0006] A drive gear is rotatably mounted on the top of the supporting door panel. The drive gear is fixedly connected to the output end of the motor through a limiting shaft. The motor is fixedly installed inside the supporting door panel. One side of the drive gear meshes with the driven gear. The middle part of the driven gear is rotatably sleeved on the connecting shaft. The connecting shaft is fixedly connected to the pin in the middle of the large hinge at the top of the door leaf. A fixed shaft is provided on one side of the connecting shaft. One end of the fixed shaft is fixedly sleeved on the top side of the door leaf, and the other end of the fixed shaft is fixedly sleeved inside the driven gear.

[0007] Infrared sensors are symmetrically fixedly installed on the top of the door leaf. The infrared sensors are electrically connected to the controller fixedly installed on the side wall of the supporting door panel. The controller is electrically connected to the motor.

[0008] Preferably, the top sidewalls of the door leaf and the supporting door panel are provided with through holes, and the bottom corners of the limiting post and the fixing post are provided with mounting holes.

[0009] Preferably, the bottom of the door leaf is fixedly connected to the mounting base of the caster wheel, and the caster wheel is arranged in a linear array about the bottom of the door leaf.

[0010] Preferably, one end of the limiting shaft is fixedly connected to the output end of the motor, and the other end of the limiting shaft is rotatably sleeved on the top of the door leaf.

[0011] Preferably, a power supply box is provided on the lower side of the controller, and the power supply box is electrically connected to the motor, infrared sensor and controller.

[0012] Preferably, the power supply box, motor, and controller are equipped with a protective cover on one side of the external cover. One side of the protective cover is fixedly connected to the support door panel, and the other side of the protective cover is hinged to the cover plate through a small hinge. The protective cover and the cover plate are locked together by a lock, and a ventilation mesh plate is fixedly installed on the cover plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model optimizes the overall appearance design of the small gate by embedding the drive motor inside the support gate panel, making the motor hidden within the support gate panel, thus making it more aesthetically pleasing and structurally balanced. At the same time, the embedded motor installation avoids the problem of traditional vertical motors occupying a large vertical space, allowing for more flexible gate height design. This makes it suitable for locations with height restrictions, such as doorway entrances and exits, thereby improving passage convenience.

[0015] 2. This utility model, by setting a meshing transmission structure of a drive gear disc and a driven gear disc at the top of the supporting gate panel, and cooperating with a connecting shaft and a fixed shaft to limit the gate leaf, allows the gate leaf to avoid the "tooth sweeping" phenomenon when forcibly pushed by external force through the displacement interleaving characteristics of the gear transmission structure, thereby improving the durability and reliability of the small gate. Furthermore, the universal wheels installed at the bottom of the gate leaf further optimize the opening and closing flexibility of the gate leaf, reduce resistance, and extend its service life.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1: Please refer to Figures 1-4This utility model provides a technical solution: a motor drive structure suitable for small gates, comprising: a gate leaf 1, one side of which is hinged to one side of a supporting gate plate 3 via large hinges 2, facilitating the opening and closing of the gate leaf 1; the other side of the gate leaf 1 abuts against a limiting post 4, which limits the gate leaf 1; the other side of the supporting gate plate 3 is fixedly connected to a fixing post 5, which provides fixed support for the supporting gate plate 3; a drive gear 6 is rotatably mounted on the top of the supporting gate plate 3; the drive gear 6 is fixedly connected to the output end of a motor 7 via a limiting shaft 21; the motor 7 is fixedly installed inside the supporting gate plate 3 using an embedded installation method; one side of the drive gear 6 meshes with a driven gear 8 for transmission; the driven gear... The gear disc 8 is rotatably mounted on the connecting shaft 9, which limits the driven gear disc 8. The connecting shaft 9 is fixedly connected to the pin in the middle of the large hinge 2 at the upper end of the door leaf 1. The side walls of the door leaf 1 and the supporting door panel 3 are provided with mounting grooves for the blades of the large hinge 2. A fixed shaft 10 is provided on one side of the connecting shaft 9. One end of the fixed shaft 10 is fixedly mounted on the top side of the door leaf 1, and the other end is fixedly mounted in the driven gear disc 8. Infrared sensors 11 are symmetrically fixedly mounted on the top of the door leaf 1. The infrared sensors 11 determine whether a person is approaching by emitting an infrared beam and detecting its reflected signal. The infrared sensors 11 are electrically connected to the controller 12 fixedly mounted on the side wall of the supporting door panel 3. The controller 12 is electrically connected to the motor 7.

[0023] The supporting door panel 3 is fixed by the fixed column 5, and the limiting column 4 limits the door leaf 1. In use, the infrared sensor 11 emits an infrared beam and detects its reflected signal to determine whether a person is approaching. When a person enters the sensing area, the infrared sensor 11 will immediately transmit the signal to the controller 12. After receiving the information, the controller 12 will immediately start the motor 7. The motor 7 will drive the drive gear 6 to move through the limiting shaft 21, causing the drive gear 6 to rotate towards the side closer to the controller 12. The drive gear 6 will then mesh with the driven gear 8. The driven gear 8 will rotate through the limiting of the connecting shaft 9. Then, the driven gear 8 will drive the door leaf 1 to move through the connection of the fixed shaft 10. The door leaf 1 is hinged to the supporting door panel 3 through the large hinge 2, thereby realizing the rotation of the door leaf 1 and finally realizing the opening of the door leaf 1 to facilitate the passage of pedestrians. When a pedestrian passes through, the controller 12 controls the motor 7 to rotate in the opposite direction, thereby closing the door leaf 1 until one side of the door leaf 1 abuts against the limiting column 4.

[0024] Example 2: Based on Example 1, through holes 13 are provided on the top sidewalls of both door leaf 1 and supporting door panel 3. The through holes 13 facilitate the rotation of the drive gear 6 and driven gear 8. Mounting holes 14 are provided at the four corners of the bottom of the limiting post 4 and the fixing post 5. The mounting holes 14 facilitate the fixing of the limiting post 4 and the fixing post 5 to the ground. The fixing post 5 fixes the supporting door panel 3, and the limiting post 4 limits the door leaf 1. The bottom of the door leaf 1 is fixedly connected to the mounting base of the universal wheel 15. The universal wheel 15 is arranged in a linear array about the bottom of the door leaf 1. By installing several universal wheels 15 at the bottom of the door leaf 1, the door leaf 1 can be opened and closed more smoothly, improving the flexibility of the door leaf 1, reducing resistance, and thus increasing the service life of the door leaf 1. One end of the limiting shaft 21 is fixedly connected to the output end of the motor 7, and the other end of the limiting shaft 21 is rotatably sleeved on the top of the door leaf 1. The top of the door leaf 1 limits the limiting shaft 21.

[0025] Example 3: Based on Example 2, a power supply box 16 is provided on the lower side of the controller 12. The power supply box 16 is electrically connected to the motor 7, infrared sensor 11, and controller 12. The power supply box 16 supplies power to each electrical component, thereby ensuring the stability of the entire device during use. A protective cover 17 is provided on one side of the power supply box 16, motor 7, and controller 12. One side of the protective cover 17 is fixedly connected to the support door panel 3, and the other side of the protective cover 17 is hinged to the cover plate 18 via a small hinge. The protective cover 17 and the cover plate 18 are connected by a lock. The head 19 is locked and connected. A ventilation mesh plate 20 is fixedly installed on the cover plate 18. By covering the power supply box 16, motor 7, and controller 12 with a protective cover 17 and the cover plate 18, the power supply box 16, motor 7, and controller 12 are protected and prevented from being touched by other personnel. The protective cover 17 and the cover plate 18 are locked by the lock head 19, which further improves the safety during use. The ventilation mesh plate 20 installed on the cover plate 18 dissipates heat from the internal space enclosed by the protective cover 17 and the cover plate 18, thereby preventing the internal electrical components from overheating and being damaged, which would affect the normal opening and closing of the door 1.
