Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-collision devices, and particularly relates to an anti-collision mechanism for an inner door at an entrance of a parking garage. Background Art
[0002] With the improvement of living standards, motor vehicles have become the main means of transportation for people, so the number of parking garages has gradually increased. Each smart parking garage is equipped with one or more dedicated entrance and exit rooms. The driver drives the vehicle smoothly into these rooms. After parking, the driver walks out of the room and touches the parking button. At this time, the outer door will close quickly to ensure that people are completely isolated from vehicles and equipment. After the outer door is completely closed, the inner door will open automatically, and then the smart vehicle transporter will enter the room to be responsible for the vehicle transport work.
[0003] When the outer door is kept open, the inner door is always kept closed. However, the existing garage entrance inner door is usually designed with a fast rolling shutter door and is made of thin iron sheets, so it is slightly insufficient in terms of impact resistance. Some drivers accidentally rush into the entrance and exit room due to poor driving skills or mistakenly stepping on the pedal. In the case of a large impact force, the inner door may be broken, causing the vehicle to fall into the lane, resulting in casualties. Utility Model Content
[0004] The utility model provides an anti-collision mechanism for the inner door of a parking garage entrance, which is used to solve the above technical problems.
[0005] In order to achieve the above-mentioned object, the utility model is implemented by the following technical scheme: A parking garage entrance inner door anti-collision mechanism comprises a door frame, an anti-collision bar, a lifting assembly and a chain counterweight. The door frame has sliding tracks on opposite sides, and the anti-collision bar is slidably mounted on two sliding tracks on opposite sides. The lifting assembly is mounted on the door frame, and the lifting assembly has a first chain and a second chain, and one end of the first chain and the second chain is mounted on the anti-collision bar. The chain counterweight is mounted on the other end of the first chain and the second chain.
[0006] The utility model provides a parking garage entrance inner door anti-collision mechanism. When in use, the lifting assembly is opened to enable the first chain and the second chain to operate, and the anti-collision bar is lifted upward steadily. During this process, the chain counterweight moves downward synchronously. When the anti-collision bar needs to be lowered, the lifting assembly drives the first chain and the second chain to move, so as to drive the anti-collision bar to move downward. At this time, the chain counterweight moves upward accordingly.
[0007] Optionally, a channel is provided on the door frame, and a first through hole and a second through hole are provided at the bottom of the channel, one end of the first chain extends into the channel and is connected to the anti-collision bar through the first through hole, and one end of the second chain extends into the channel and is connected to the anti-collision bar through the second through hole.
[0008] Optionally, a parking garage entrance inner door anti-collision mechanism further includes a first steering wheel and a second steering wheel. The first steering wheel is rotatably mounted in the channel, one end of the first chain extends into the channel, the direction of the first chain is adjusted by the first steering wheel, and the first chain passes through the first through hole so that the first chain is connected to the anti-collision bar. The second steering wheel is rotatably mounted in the channel, one end of the second chain extends into the channel, the direction of the second chain is adjusted by the second steering wheel, and the second chain passes through the second through hole so that the second chain is connected to the anti-collision bar, and the first steering wheel and the second steering wheel are spaced apart.
[0009] Optionally, the lifting assembly includes a lifting motor and a motor sprocket. The lifting motor is mounted on the door frame and arranged close to the passage. The motor sprocket is mounted on the output shaft of the lifting motor, and the other ends of the first chain and the second chain pass through the motor sprocket and are connected to the chain counterweight.
[0010] Optionally, the parking garage entrance inner door anti-collision mechanism further comprises sliding wheels which are rotatably mounted on both sides of the anti-collision bar and slide relative to the sliding track to adjust the height of the anti-collision bar relative to the door frame.
[0011] Optionally, a parking garage entrance inner door anti-collision mechanism further includes a limit collision plate, an upper limit plate and a lower limit plate. The limit collision plate is mounted on the anti-collision rod. The upper limit plate is mounted on the side wall of the door frame and is arranged close to the passage. The lower limit plate is mounted on the side wall of the door frame and is located below the upper limit plate.
[0012] It can be seen from the above technical solution that the beneficial effect of the anti-collision mechanism for the inner door of the parking garage entrance provided by the utility model is that when the inner door is in the open state, the anti-collision bar is driven to move upward by the lifting assembly to provide sufficient space for vehicles and equipment to enter and exit, ensuring unimpeded access. When the inner door is closed, the anti-collision bar is lowered by the lifting assembly and firmly blocked in front of the inner door, forming an effective safety barrier. Such a design not only ensures the safety of personnel and vehicles, but also avoids potential risks caused by misoperation or unexpected situations. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Example
[0024] The existing garage entrance inner door is usually designed with fast rolling shutter doors and is made of thin iron sheets, so it is slightly insufficient in terms of impact resistance. Some drivers accidentally rush into the entrance and exit room due to poor driving skills or mistakenly stepping on the pedal. In the case of a large impact, the inner door may be broken, causing the vehicle to fall into the lane, resulting in casualties.
[0025] In order to solve the above technical problems, refer to Figure 1 and Figure 2 As shown, the present embodiment provides a parking garage entrance inner door anti-collision mechanism including a door frame 1, an anti-collision bar 7, a lifting assembly and a chain counterweight 8. The door frame 1 has sliding rails 6 on opposite sides, and the anti-collision bar 7 is slidably mounted on two sliding rails 6 on opposite sides. The lifting assembly is mounted on the door frame 1, and the lifting assembly has a first chain 4 and a second chain 5, and one end of the first chain 4 and the second chain 5 is mounted on the anti-collision bar 7. The chain counterweight 8 is mounted on the other end of the first chain 4 and the second chain 5. The anti-collision bar 7 is welded from a solid 120*80*4mm rectangular tube and has excellent anti-collision performance. Even in the case of a collision caused by misoperation of the machine, it can effectively protect the car from falling into the lane, thereby ensuring the personal safety of the parking personnel. The sliding track 6 is also welded from a 120*80*4mm rectangular tube to ensure its high strength and stability. It is worth mentioning that the rising and falling speed of the anti-collision bar is basically consistent with the opening and closing speed of the inner door. Therefore, the time for storing and retrieving the car will not be extended due to the addition of this mechanism, ensuring the high efficiency of parking.
[0026] Through the above structure, the embodiment provides a parking garage entrance inner door anti-collision mechanism, opens the lifting assembly, so that the first chain 4 and the second chain 5 are operated, and the anti-collision bar 7 is smoothly lifted upward. In this process, the chain counterweight 8 moves downward synchronously. When the anti-collision bar 7 needs to be lowered, the first chain 4 and the second chain 5 are driven by the lifting assembly to move the chain, so as to drive the anti-collision bar 7 to move downward. At this time, the chain counterweight 8 moves upward accordingly.
[0027] On the basis of the above, refer to Figure 4As shown, a channel is provided on the door frame 1, and a first through hole and a second through hole are provided at the bottom of the channel. One end of the first chain 4 extends into the channel and is connected to the anti-collision bar 7 through the first through hole. One end of the second chain 5 extends into the channel and is connected to the anti-collision bar 7 through the second through hole. A parking garage entrance inner door anti-collision mechanism also includes a first steering wheel 13 and a second steering wheel 14. The first steering wheel 13 is rotatably installed in the channel, one end of the first chain 4 extends into the channel, the direction of the first chain 4 is adjusted by the first steering wheel 13, and the first chain 4 passes through the first through hole so that the first chain 4 is connected to the anti-collision bar 7. The second steering wheel 14 is rotatably installed in the channel, one end of the second chain 5 extends into the channel, the direction of the second chain 5 is adjusted by the second steering wheel 14, and the second chain 5 passes through the second through hole so that the second chain 5 is connected to the anti-collision bar 7, and the first steering wheel 13 and the second steering wheel 14 are arranged at intervals.
[0028] On the basis of the above, refer to Figure 1 As shown, the lifting assembly includes a lifting motor 2 and a motor sprocket 3. The lifting motor 2 is mounted on the door frame 1 and is arranged close to the passage. The motor sprocket 3 is mounted on the output shaft of the lifting motor 2, and the other ends of the first chain 4 and the second chain 5 pass through the motor sprocket 3 and are connected to the chain counterweight 8. The lifting motor 2 rotates to drive the motor sprocket 3 to rotate, thereby causing the first chain 4 and the second chain 5 to move to drive the anti-collision bar 7 to slide along the sliding track 6, thereby causing the chain counterweight 8 to move in the opposite direction to the anti-collision bar 7. The chain counterweight 8 effectively balances the anti-collision bar 7 and tightens the first chain 4 and the second chain 5 to prevent them from getting entangled with each other. The motor sprocket 3 adopts an advanced double-row sprocket design, which perfectly fits the two chains before and after the anti-collision bar 7, and transmits power more efficiently. In addition, a reasonable safety distance is set between the first chain 4 and the second chain 5 to effectively prevent interference between the chains.
[0029] On the basis of the above, refer to Figure 3 As shown, a parking garage entrance inner door anti-collision mechanism also includes sliding wheels 12. The sliding wheels 12 are rotatably mounted on both sides of the anti-collision bar 7, and the sliding wheels 12 slide relative to the sliding track 6 to adjust the height of the anti-collision bar 7 relative to the door frame 1. A total of four sliding wheels 12 are installed on both sides of the anti-collision bar 7, and the sliding wheels 12 may have grooves, which are stuck on the sliding track 6 when moving up and down, ensuring that the anti-collision bar 7 moves up and down smoothly.
[0030] On the basis of the above, refer to Figure 1 and Figure 2As shown, a parking garage entrance inner door anti-collision mechanism also includes a limit collision plate 9, an upper limit plate 10 and a lower limit plate 11. The limit collision plate 9 is installed on the anti-collision rod 7. The upper limit plate 10 is installed on the side wall of the door frame 1 and is arranged close to the passage. The lower limit plate 11 is installed on the side wall of the door frame 1 and is located below the upper limit plate 10.
[0031] In summary, in the use of a parking garage entrance inner door anti-collision mechanism, first, after the lifting motor 2 is started, its power is quickly transmitted to the motor sprocket 3, causing it to start rotating. Subsequently, the first chain 4 is guided by the first steering wheel 13, and the second chain 5 is guided by the second steering wheel 14, and the anti-collision bar 7 is smoothly lifted upward. In this process, the chain counterweight 8 moves downward synchronously to ensure that the first chain 4 and the second chain 5 are always kept in a taut state, effectively preventing the entanglement between the chains. When the anti-collision bar 7 rises to a certain position, the limit collision plate 9 abuts against the upper limit plate 10, the lifting motor 2 stops working immediately, and the anti-collision bar 7 accurately reaches the predetermined position. At this time, the inner door is opened and the equipment can operate normally. When the anti-collision bar 7 needs to be lowered, the lifting motor 2 is reversed, and the first chain 4 and the second chain 5 drive the anti-collision bar 7 to move slowly downward. At this time, the chain counterweight 8 moves upward accordingly to maintain the taut state of the first chain 4 and the second chain 5. When the anti-collision bar 7 drops to a certain position, the limit collision plate 9 abuts against the lower limit plate 11, and the lifting motor 2 stops rotating again, and the anti-collision bar 7 stays stably at this position until the next operation instruction is received. It is worth mentioning that in this state, if a person makes an error in operation and causes the car to crash into the inner door, the anti-collision bar is 0.8 meters above the ground, which is exactly the position of the front of most cars. Therefore, it can effectively prevent the car from crossing the anti-collision bar and crashing into the inner door, thereby protecting the safety of the vehicle and the driver to the greatest extent. The entire system process is cleverly designed, which not only ensures the convenience of operation, but also guarantees the safety of use.
[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
