Description

Technical Field

[0001] This utility model relates to the field of garage door technology, and in particular to an intelligent three-dimensional garage door device with multiple security protections. Background Technology

[0002] Multi-level parking garage doors with multiple safety features are crucial for ensuring the safety of vehicles, personnel, and equipment. They integrate various technologies such as anti-pinch sensors, emergency braking, structural limits, and status monitoring to create a comprehensive safety barrier. This not only effectively prevents accidents such as crushing and collisions caused by mechanical failure or operational errors, ensuring a smooth and reliable parking and retrieval process, but also significantly reduces safety risks through multiple protective designs, providing users with a safer and more convenient parking experience.

[0003] In existing technologies, garage doors mostly rely on safety light curtains installed inside the doors for obstacle detection. However, this method has obvious limitations. Due to the thickness of the garage door, the detection range of the safety light curtain is limited, resulting in a large blind spot. When a vehicle partially protrudes, the garage door may have already collided with it, but the light curtain is not blocked and cannot trigger an alarm or stop the action, leading to vehicle damage or even a safety accident.

[0017] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-6 This utility model provides an embodiment of an intelligent three-dimensional garage door device with multiple safety protections, including a lower plate 11, a door frame 13 on the lower plate 11, an upper plate 12 on the door frame 13, sliding doors 31 on the left and right sides of the door frame 13, a drive assembly installed on the upper plate 12, the two sliding doors 31 being able to move towards each other, a protruding plate 32 on the sliding door 31, a touch assembly on the side of the protruding plate 32 facing the opposite sliding door 31, an insert block on the sliding door 31, a guide groove 110 on the lower plate 11 for guiding the insert block, a first safety component on the door frame 13, the first safety component including a first safety light curtain 21 disposed opposite to each other, a second safety component on the protruding plate 32, the second safety component including a second safety light curtain 23 that moves with the protruding plate 32. By setting up a double sliding door 31 structure in conjunction with the upper and lower plates 11 and the door frame 13 to form a stable frame, and by using the first safety light curtain 21 of the first safety component and the second safety light curtain 23 of the second safety component, a three-dimensional coverage of the garage door area is achieved. Under the monitoring of the first safety component and the second safety component, the system can detect in advance that it may run over an obstacle, drive the motor 123 to decelerate, and reduce the frequency of emergency braking of the motor 123. The lower part of the sliding door 31 is provided with an insert block that cooperates with the guide groove 110 to provide lower guide support, prevent the door from swinging, and improve operational safety.

[0019] Please see Figure 1-6A further embodiment of this solution is as follows: the triggering component includes a floating plate 36, on which a first round rod 361 is provided, through which a protrusion 32 passes. A triggering plate 362 is threadedly connected to the first round rod 361. A micro switch 35 is installed on the sliding door 31. When the floating plate 36 is pressed, it can move towards the sliding door 31, causing the triggering plate 362 to press the input end of the micro switch 35. The floating triggering component employs a mechanical triggering mechanism, resulting in rapid response and high reliability. When the two sliding doors 31 encounter an obstacle during closing, the floating plate 36 is compressed and retracted by external force, causing the triggering plate 362 to trigger the micro switch 35, immediately sending a stop signal to the control system, causing the motor 123 to brake. This structure avoids rigid collisions.

[0020] Please see Figure 2-4 A further embodiment of this solution is as follows: A first spring 363 is sleeved on the first round rod 361 corresponding to the interval between the protruding plate 32 and the actuating plate 362. A second round rod 321 is provided on the protruding plate 32, and a second spring 322 is sleeved on the second round rod 321 corresponding to the interval between the floating plate 36 and the protruding plate 32. The floating plate 36 has a through hole 360 ​​for the second round rod 321 to pass through. The synergistic effect of the first spring 363 and the second spring 322 keeps the floating plate 36 in a balanced state, and at the same time provides an active restoring force after the floating plate 36 is pressed.

[0021] Please see Figure 2-4 A further embodiment of this solution is as follows: the floating plate 36 is also provided with a guide rod 34, and the protruding plate 32 is provided with a guide hole corresponding to the guide rod 34. The cooperation between the guide rod 34 and the guide hole restricts the floating plate 36 to only move linearly along the axial direction, ensuring that the touch plate 362 can accurately align with the trigger point of the micro switch 35, thereby improving the reliability of the triggering action.

[0022] Please see Figure 1-2 A further embodiment of this solution is as follows: the drive assembly includes a movable block 33 mounted on the sliding door 31, two fixed seats 121 mounted on the upper plate 12, and a bidirectional screw 122 rotatably connected between the two fixed seats 121. The movable block 33 is engaged with the bidirectional screw 122, and a motor 123 for driving the bidirectional screw 122 to rotate is mounted on the fixed seat 121. By using the bidirectional screw 122 drive method, the motor 123 drives the screw to rotate, causing the movable blocks 33 on both sides to move synchronously inward or outward, thereby achieving synchronous opening and closing of the two sliding doors 31.

[0023] Please see Figure 1-2A further solution based on this embodiment is as follows: a dovetail block 124 is provided on the upper plate 12, and a dovetail groove 310 corresponding to the dovetail block 124 is provided on the sliding door 31. The dovetail block 124 is used to support the sliding door 31. The cooperative structure of the dovetail block 124 and the dovetail groove 310 provides upper rigid support and guidance for the sliding door 31, effectively bearing the weight of the sliding door 31 and preventing it from sagging or swaying during operation. The dovetail structure has strong resistance to lateral forces, significantly improving the stability of the door operation.

[0024] Please see Figure 3-5 A further solution based on this embodiment is as follows: Mounting plates 221 are respectively provided at both ends of the first safety light curtain 21 and the second safety light curtain 23. The mounting plates 221 have several circular holes 222 for bolts to pass through, and also have elongated holes 223 connecting the circular holes 222. The diameter of the circular holes 222 is larger than the width of the elongated holes 223. By providing the circular holes 222 and elongated holes 223 on the mounting plates 221, when the first safety light curtain 21 or the second safety light curtain 23 is accidentally impacted by a vehicle, the bolts can pass through the current circular hole 222 along the elongated holes 223 into other circular holes 222, thus mitigating the impact force of the vehicle by destroying the current circular hole 222. The mounting plates 221 need to be replaced promptly after damage, and the reusability of the first safety light curtain 21 or the second safety light curtain 23 should be evaluated.

[0025] Please see Figure 1-2 A further solution based on this embodiment is as follows: a stop assembly is provided on the inner side of the door frame 13, the stop assembly including an emergency stop button 131, the emergency stop button 131 is used to trigger the motor 123 to brake urgently. The emergency stop button 131 allows personnel to quickly and manually cut off the power to the motor 123 and brake it from the end of the door frame 13 away from the sliding door 31, so as to achieve a rapid stop of the door.

[0026] For a second embodiment of the stop component, please refer to [link / reference]. Figure 6 The installation of the emergency stop button 131 is eliminated. An extension plate 37 is set on the protruding plate 32. When the personnel cannot reach the protruding plate 32, they can strike the extension plate 37 to force the first round rod 361 to move. This can also cut off the power to the motor 123 and brake the door to stop quickly. This is suitable for scenarios where the customer's specification book does not have a strict requirement for the emergency stop button 131, and can reduce the trouble of installing and wiring the emergency stop button 131.

[0027] Working Principle: When the intelligent automated parking garage door device with multiple safety protections is in operation, the motor 123 starts and drives the bidirectional screw 122 to rotate. Through the meshing transmission between the bidirectional screw 122 and the two side moving blocks 33, the two sliding doors 31 move synchronously towards or away from each other along the dovetail block 124 of the upper plate 12 and the guide groove 110 of the lower plate 11, completing the opening and closing of the garage door. During the closing process, the two first safety light curtains 21 of the first safety component are arranged on both sides of the front of the door frame 13, forming a front infrared detection area that can detect whether there are obstacles in the middle of the door in real time. At the same time, the two second safety light curtains 23 of the second safety component and the corresponding upper convex plate 32 of the sliding door 31 are fixed to form a rear infrared detection area. When any light curtain detects an obstacle, the control system immediately reduces the speed of the motor 123 and prepares to brake to avoid high-speed impact and improve the predictive ability of the safety response. If an obstacle is located between the two sliding doors 31, upon collision, it first touches the floating plate 36. Under pressure, the floating plate compresses along the guide rod 34 towards the sliding door 31, causing the touch plate 362 on the first round rod 361 to press the micro switch 35, triggering a mechanical power-off signal. This causes the motor 123 to quickly lose power and initiate braking. The motor 123 here has a braking function, achieving rapid emergency stop. After the obstacle is removed, the floating plate 36 resets under the combined action of the first spring 363 and the second spring 322, returning to its initial equilibrium position, ensuring reliable reuse. When a person is between the two sliding doors 31 and an emergency requires manual intervention, the operator can directly press the emergency stop button 131 located inside the door frame 13. In embodiments without an emergency stop button 131, striking the extension plate 37 outside the protruding plate 32 simulates the obstacle's impact, forcibly pushing the floating plate 36 to trigger the micro switch 35, achieving an equivalent emergency braking function. In addition, the first safety light curtain 21 and the second safety light curtain 23 are fixed by a mounting plate 221 with a round hole 222 and a long hole 223. In the event of an accidental vehicle collision, the bolts can be guided out of the original mounting hole by the long hole 223. The local deformation of the mounting plate 221 absorbs the impact energy, reducing the possibility of direct damage to the light curtain body, minimizing maintenance costs, and facilitating subsequent evaluation and maintenance. The system here is written into a programmable controller. The first safety light curtain 21, the second safety light curtain 23, the micro switch 35, and the motor 123 are all existing technologies. The corresponding working principles and wiring methods will not be described here. The guide groove 110 needs to be cleaned regularly by personnel. The dovetail block 124 and the bidirectional screw 122 need to be lubricated regularly. The second round rods 321 on different protrusions 32 can contact each other through the through hole 360 ​​to prevent the floating plate 36 from moving and triggering the micro switch 35 when the door is closed normally.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
