Description

Technical Field

[0001] This utility model relates to the field of door opener technology, and in particular to an electric wheeled door opener. Background Technology

[0002] A gate opener is a type of drive consisting of a motor, a speed-changing mechanism, and a clutch device. It is an electromechanical product and is typically used to electrically open and close various gates. Wheeled gate openers are usually installed at the bottom center of the gate and run close to the ground. However, there are often obstacles such as small stones on the ground in outdoor courtyards. When a wheeled gate opener drives the gate to rotate, the rollers can easily be damaged when they come into contact with the small stones, and the rollers can also easily get stuck during operation.

[0003] An automatic obstacle-removing wheeled door opener, disclosed in Chinese patent application number 202121912480.0, includes a chassis. Rollers are rotatably mounted on both sides of the top of the chassis. A main drive mechanism for driving the rollers is located on the top of the chassis. Two symmetrically arranged gear shafts are rotatably mounted on both sides of the bottom of the chassis. Two gear shafts on the same side of the chassis are connected by a toothed belt. Multiple cleaning blades are fixedly connected to the outer side of the toothed belt. A secondary drive mechanism for synchronously rotating the two gear shafts is located at the bottom of the chassis. In this technical solution, the output shafts at both ends of a second dual-shaft drive motor drive the active gear to rotate, which in turn drives the driven gear to rotate the gear shaft. This causes the toothed belt to rotate around the two gear shafts, and the cleaning blades continuously contact the ground, sweeping away small stones and other obstacles along the roller's trajectory, preventing damage to the roller and avoiding jamming.

[0004] However, the following problems still exist in this technical solution: the active gear drives the driven gear to rotate the gear shaft, which in turn causes the toothed belt to rotate around the gear shafts on both sides. The sweeping blades continuously contact the ground to sweep away obstacles. However, the toothed belt, gear shafts, and sweeping blades are all exposed outside the machine casing. If it rains, the sweeping blades will get wet and more easily carry away dirt. When the sweeping blades with dirt rotate above the gear shafts, sewage can easily flow onto the gear shafts and form dirt, which will affect the normal transmission of the gear shafts. As a result, the sweeping blades cannot sweep away obstacles, affecting the operation of the gate opener. Utility Model Content

[0005] The purpose of this invention is to provide an electric wheeled door opener to solve the above-mentioned problems.

[0006] The technical solution of this utility model is implemented as follows:

[0007] This utility model provides an electric wheeled gate opener, including a gate opener body and a wheel assembly. The wheel assembly is located at the bottom of the gate opener body and is used to drive the gate opener body to move. The key feature is that: two symmetrical mounting brackets are fixed on the front and rear sides of the gate opener body. Each mounting bracket has a downwardly extending mounting groove. A mounting bracket is slidably arranged in the mounting groove, and a cleaning component is rotatably arranged between the two mounting brackets. An electric telescopic rod matching the mounting groove is provided inside the gate opener body. The telescopic end of the electric telescopic rod is fixed to the mounting bracket. Rain shields are also provided on the front and rear sides of the gate opener body that can be flipped. When the mounting bracket is located at the high point of the mounting groove, the rain shield flips and covers the cleaning component.

[0008] In one embodiment, two symmetrical fixing members are fixed on the front and rear sides of the main body of the gate opener. The rain shield is rotatably disposed between the two fixing members. A snap-fit ​​member is fixed on the side of the rain shield facing the main body of the gate opener. A slot for engaging the snap-fit ​​member is provided on the main body of the gate opener. A traction member is also fixed on the rain shield. The traction member extends toward the mounting groove and is located on the sliding trajectory of the mounting bracket from the low to the high point of the mounting groove.

[0009] In one embodiment, the end of the rain shield away from the fixing member extends in an arc towards the bottom of the cleaning assembly.

[0010] In one embodiment, a drainage plate is fixed to the arc-shaped end of the rain shield, and the drainage plate is inclined toward the bottom of the cleaning assembly.

[0011] In one embodiment, at least one scraper is fixed on the drainage plate.

[0012] In one embodiment, the side of the rain shield used for rain protection is set as an inclined surface, and the height of the inclined surface decreases from the end closer to the gate operator body to the end farther away from the gate operator body.

[0013] The advantages or beneficial effects of the above technical solutions include at least the following:

[0014] In this invention, the cleaning component is positioned between two mounting brackets. Under the action of the electric telescopic rod, the two mounting brackets can slide within the inclined mounting groove. When the weather is sunny, the mounting bracket is located at the lowest point of the mounting groove, at which time the cleaning brush head contacts the ground to achieve a cleaning effect. When it rains, the electric telescopic rod retracts, allowing the component to move directly to the highest point of the mounting groove. At this time, the cleaning brush head does not contact the ground, and the rain shield flips down to cover the top of the cleaning component, thereby reducing the impact of rainwater on the cleaning component.

[0026] Reference Figures 1-4 An electric wheeled gate opener includes a gate opener body 1 and a wheel assembly. The wheel assembly is located at the bottom of the gate opener body 1 and is used to move the gate opener body 1. Two symmetrical mounting brackets 2 are fixed on both the front and rear sides of the gate opener body 1. Each mounting bracket 2 has a downwardly extending mounting groove 3. Mounting supports 4 are slidably mounted within the mounting grooves 3, and a cleaning component is rotatably mounted between the two mounting supports 4. An electric telescopic rod 5, matching the mounting grooves 3, is installed inside the gate opener body 1. The telescopic end of the electric telescopic rod 5 is fixed to the mounting support 4. Rain shields 6 are also rotatably mounted on the front and rear sides of the gate opener body 1. When the mounting supports 4 are at the high point of the mounting grooves 3, the rain shields... 6. When the mounting bracket 4 is flipped over and covers the top of the cleaning assembly, in sunny weather, the cleaning part of the cleaning assembly is in contact with the ground. When the gate opener is moving, the cleaning part can sweep away obstacles such as small stones on the ground to prevent them from affecting the normal operation of the gate opener. On rainy days, the telescopic end of the electric telescopic rod 5 will retract, causing the mounting bracket 4 to slide to the higher part of the mounting groove 3. When the mounting bracket 4 is at the highest point of the mounting groove 3, the cleaning part of the cleaning assembly will not contact the ground, so that it will not bring up sewage on the ground. At the same time, the rain shield 6 can completely cover the top of the cleaning assembly after flipping over, preventing rainwater from entering the cleaning assembly from above.

[0027] In one specific embodiment, the wheel assembly includes a main drive shaft and rollers. The main drive shaft is rotatably mounted inside the main body 1 of the gate opener, while the rollers are sleeved on the outside of the main drive shaft. The main body 1 of the gate opener is equipped with a motor that drives the main drive shaft to rotate. This motor is a DC motor, and it is connected to a signal transmitter via a circuit. This signal transmitter is matched with the controller of the gate opener. The electric telescopic rod 5 is also connected to the signal transmitter via a circuit. The cleaning assembly includes a driven shaft, which is rotatably mounted between two mounting brackets 4. The main drive shaft is fitted with a leather sleeve on its outer side, and several cleaning brush heads are mounted on the leather sleeve. Both ends of the main drive shaft are fitted with belts. One end of the leather sleeve is fitted onto the driven drive shaft on the front side of the main body 1 of the gate opener, and the other end of the leather sleeve is fitted onto the driven drive shaft on the rear side of the main body 1 of the gate opener. In this way, when the motor drives the main drive shaft to rotate, the rollers rotate and the main body 1 of the gate opener moves. At the same time, since the driven drive shaft is connected to the main drive shaft through the belt, the driven drive wheel will also rotate with the main drive wheel, causing the cleaning brush heads to rotate and sweep away obstacles on the ground.

[0028] In one specific embodiment, the main body 1 of the gate opener is provided with a fixing frame for installing the electric telescopic rod 5, and the electric telescopic rod 5 is inclined, with its inclination angle being level with the mounting groove 3. The main body 1 of the gate opener is provided with a slot at the extension position of the telescopic end of the electric telescopic rod 5, so that the telescopic end of the electric telescopic rod 5 can extend out of the main body 1 of the gate opener. At the same time, the mounting frame 2 is also provided with a through opening corresponding to the position of the slot. The telescopic end of the electric telescopic rod 5 passes through the slot and the through opening and is connected to the mounting bracket 4. In this way, as the telescopic end of the electric telescopic rod 5 extends or retracts, the mounting bracket 4 can slide downward or upward within the mounting groove 3.

[0029] In one specific embodiment, since the cleaning brush head is mounted on a leather sleeve, which is fitted on the outside of the drive shaft, if the cleaning brush head becomes dirty or severely worn after prolonged use, resulting in poor cleaning performance, the drive shaft can be removed directly, the leather sleeve can be taken off, and a new leather sleeve with a new cleaning brush head can be installed. This immediately restores the cleaning performance of the cleaning brush head to its original state. The removed leather sleeve can then be cleaned or repaired depending on the situation, or it can be scrapped if it is severely worn. This design avoids the need to wait for the cleaning process to be completed before the cleaning effect can be achieved when the cleaning brush head is removed for cleaning or repair.

[0030] Reference Figures 1-3The main body 1 of the gate opener has two symmetrical fixing parts 7 fixed on its front and rear sides. The rain shield 6 is rotatably disposed between the two fixing parts 7. The side of the rain shield 6 facing the main body 1 of the gate opener has a snap-fit ​​part 8 fixed on it, and the main body 1 of the gate opener has a slot 9 that fits into the snap-fit ​​part 8. The rain shield 6 also has a traction part 10 fixed on it. The traction part 10 extends toward the mounting groove 3 and is located on the sliding trajectory of the mounting bracket 4 from the low point to the high point of the mounting groove 3. With this arrangement, when the rain shield 6 is not needed, the snap-fit ​​part 8 is inserted into the slot 9 to connect the rain shield 6. The rain shield is fixedly stored on the surface of the main body of the door. On rainy days, as the mounting bracket 4 moves diagonally upward, the cleaning brush head and the leather sleeve will press against the traction component 10. As the pressure continues to increase, the snap-fit ​​component 8 can be disengaged from the slot 9. At this time, the rain shield 6 is unrestrained and will flip towards the mounting bracket 2 under the pressure of the traction component 10, eventually abutting against the top of the mounting bracket 2 and completely covering the cleaning components. After the weather clears up, the rain shield 6 is flipped up manually and the snap-fit ​​component 8 is embedded into the slot 9 to fix it, thus completing the storage of the rain shield 6.

[0031] In one specific embodiment, a rotating shaft is provided on the rain shield 6, and the two ends of the rotating shaft are rotatably set on the fixing member 7. At the same time, the end of the rain shield 6 that is close to the door opener body 1 is set as an arc surface, so that the rain shield 6 can rotate more smoothly.

[0032] Reference Figure 1 and Figure 3 The end of the rain shield 6 away from the fixing member 7 extends in an arc towards the bottom of the sweeping assembly. With this setting, the rain shield 6 can also cover the side of the sweeping assembly, further enhancing the waterproof effect.

[0033] Reference Figure 1 and Figure 3 The rain shield 6 has a drainage plate 11 fixed at the arc-shaped end. The drainage plate 11 is inclined towards the bottom of the sweeping assembly. With this setting, as the door opener moves and the ground is slippery on rainy days, the drainage plate 11 can push away the water and obstacles on the ground, thereby replacing the sweeping brush head and achieving a certain sweeping effect.

[0034] Reference Figure 2 and Figure 4 At least one scraper 12 is fixed on the drainage plate 11. With this arrangement, after the drainage plate 11 pushes away the accumulated water or obstacles, the scraper 12 can then sweep the road surface again to further enhance the cleaning effect.

[0035] In one specific embodiment, if consumers are still concerned about the insufficient cleaning effect of the drainage plate 11 and the scraper 12, they can also control the electric telescopic rod 5 to extend through the controller, so that the cleaning brush head contacts the ground again. Because the position of the traction member 10 is lower than before, the cleaning brush head will contact the traction member 10 when it rolls. At this time, the traction member 10 can act as a scraper under pressure, scraping off some of the sewage on the cleaning brush head, thereby reducing the impact of sewage on the cleaning components.

[0036] Reference Figure 3 and Figure 4 The rain shield 6 is designed with a slope on one side for rain protection. The height of the slope decreases from the end closer to the main body 1 of the gate operator to the end further away from the main body 1 of the gate operator. With this design, rainwater falling on the rain shield 6 can slide down the slope, avoiding the accumulation of rainwater on the rain shield 6 and increasing its weight, thereby increasing the wear between the rain shield 6 and the mounting bracket 2.
