DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

Detailed descriptions about the comb tooth type transport mechanism provided by the present invention are shown below in conjunction with figures and embodiments:

Referring to FIGS. 1 and 2, the comb tooth type transport mechanism 100 provided by the present invention includes a turntable 1, a rotating device 2, first comb teeth 3, a lifting platform 4, a lifting device 5 and a positioning roller 6. The rotating device 2 is disposed at a bottom of the turntable 1 which is driven to be rotated by the rotating device 2 in order to make the car parked on it to be turned around, so that the car can be driven to leave easily. The turntable 1 is driven by the rotating device 2 through a method in which the driven gear is driven to be rotated by the driving gear which is driven to be rotated by the motor. In other embodiments, the turntable 1 can be driven by the rotating device 2 in other ways in the prior art. The turntable 1 is provided with an opening 11 to receive the lifting platform, both the lifting platform 4 and the lifting device 5 are arranged on the turntable 1, and the lifting platform 4 is lifted or lowered by the lifting device 5 to enter or exit the opening 11. The first comb teeth 3 are fixed on the turntable 1 and parallelly arranged at opposite sides of the lifting platform 4 for the car to travel and to be parked on it. That is to say, cars need to be parked on the first comb teeth 3 after entering the comb tooth type transport mechanism 100. Since the first comb teeth 3 are composed of a plurality of rectangular tooth spaced apart, the frictional resistance to the automobile can be increased, thereby preventing the automobile from slipping during they are handled. The positioning roller 6 is disposed on the turntable 1 along the length direction of the first comb teeth 3 and is located at the end of the first comb teeth 3. The car can be restricted from moving forward and positioned on the first comb teeth 3 by the positioning roller 6. Preferably, for the car can enter or exit the comb tooth type transport mechanism 100 conveniently and avoiding the positioning roller 6 hindering the car, the positioning roller 6 is arranged on the turntable 1 and liftable relative to the turntable 1. After the car entering the comb tooth type transport mechanism 100, the positioning roller 6 is raised and the car is positioned on the first comb teeth 3. However, the positioning roller 6 is lowered when the car is transported to exist or enter the comb tooth type transport mechanism 100, thus avoiding the positioning roller 6 hindering the car. In this embodiment, two ends of the first comb teeth 3 are provided with positioning rollers 6, that is to say, there are 4 positioning rollers 6. In other embodiments, the number of positioning rollers 6 can also be set to 1, 2 or 3, etc. In order to make the devices of the comb tooth type transport mechanism 100 work together, at the same time to improve the work efficiency and the level of the automation, the positioning roller 6 is provided with an inductive switch (not shown) through which signal can be transmitted to the controller to control the positioning roller 6 thus the positioning roller 6 can be lifted or lowered.

More specifically, as shown in FIG. 1, second comb teeth 41 are disposed on opposite sides of the lifting platform 4. When the lifting platform 4 is lifted or lowered to the opening 11, the first comb teeth 3 and the second comb teeth 41 are mutually connected. In other worlds, when the first comb teeth 3 and the second comb teeth 41 are connected with each other, a passage can be formed for cars to travel and to be parked on it. Furthermore, the rectangular tooth of the second comb teeth 41 are inserted into the gaps between the respective rectangular tooth of the first comb teeth 3, thereby reducing the resistance to the car due to the gap of the first comb teeth 3 so that the car can travel on the first comb teeth 3 easily.

Referring to FIGS. 3 to 5, the comb tooth type transport mechanism 100 further includes a carrier 7 which is moved to the lifting platform 4 when the lifting platform 4 is moved to the bottom of the opening 11 after the car being parked on the first comb teeth 3. Specifically, the lifting platform 4 is provided with a slide rail 42 for the carrier 7 to be slid on it and the carrier 7 can enter or exit the lifting platform 4 along the slide rail 42. Third comb teeth 71 are provided on the opposite sides of the carrier 7 driven by the lifting platform 4 and can be connected with the first comb teeth 3. When the carrier 7 is raised, the third comb teeth 71 are raised together to pass through the first comb teeth 3 in a cooperative manner, thereby the car parked on the first comb teeth 3 can be lifted to a high position and carried into the parking garage. A vehicle centering device 72 is also disposed on the carrier 7 and is provided with push rods 721 slidably and separately configured at opposite sides of the carrier 7. In this embodiment, two push rods are driven synchronously and oppositely, that is to say, two push rods are slid separately in opposite directions. Cars which are parked not in the middle position will be moved to the middle position by push rods 721 slid synchronously from the middle to the sides. Also, in other embodiments, when the car's biased parking position has been sensed, the car can be pushed to the middle position by the push rod 721 set on one side, but not limited to this. In order to reduce the resistance when the push rod 721 pushes the car and reduce the damage to the car tire, a plurality of rollers 711 are disposed on each of the rectangular tooth of the third comb teeth 71.

Referring to FIGS. 1 to 5, the working process of the comb tooth type transport mechanism 100 is further described below.

When cars are stored, at the beginning, the second comb teeth 41 of the lifting platform 4 are connected with the first comb teeth 3 disposed on the turntable 1, thus the top surface of the first comb teeth 3 and the top surface of the second comb teeth 41 are coplanar to form a passage for the car to travel. The car enters the comb tooth type transport mechanism 100 along the first comb teeth 3 set on two sides of the comb tooth type transport mechanism 100. When the front wheel of the car touches the positioning roller 6, the car is in place and the four wheels of the car are parked on the first comb teeth 3 and the second comb teeth 41. Then the driver leaves the car. The car triggers the inductive switch and the positioning roller 6 is driven to be lowered. The lifting platform 4 is driven by the lifting device 5 and then downs to the bottom of the opening 11. The carrier 7 enters the lifting platform 4 along the slide rail 42 to the middle position. The carrier 7 driven by the lifting device 5 is raised above the position of the first comb teeth 3. More specifically, the third comb teeth 71 of the carrier 7 passes through the first comb teeth 3 in a cooperative manner and the car is lifted by the carrier 7 to a high position. Then the push rods 721 driven by the vehicle centering device 72 are slid synchronously and push the car to the middle position of the carrier 7 to complete the centering action. At last the car is removed from the comb tooth type transport mechanism 100 by the carrier 7 and stored in the parking garage.

When cars are picked up, firstly, the positioning roller 6 is lowered to avoid obstructing the carrier 7 from entering the turntable 1, the lifting platform 4 driven by the lifting device 5 is raised above the position of the first comb 3, and the car is carried by the carrier 7 to the turntable 1 along the slide rail 42. Then the lifting device 5 is lowered to the bottom of the opening 11, during this process, the first comb teeth 3 are passed through by the third comb teeth 71 of the carrier 7 in a cooperative manner and the car falls on the first comb teeth 3. After the carrier 7 being moved to leave the turntable 1 along the slide rail 42, the turntable 1 is rotated by 180 degrees for the car can be driven to leave without reversing.

In summary, the comb tooth type transport mechanism 100 provided by the present invention is provided with first comb teeth 3 on opposite sides of the lifting platform 4 on the turntable 1. And a passage for the car to travel and be parked on is formed by means of the two first comb teeth 3. Since the first comb teeth 3 can be used to prevent the car parked on it from slipping. Thus it can avoid the accident caused by the car when the car is slid during transported. Therefore, the comb tooth type transport mechanism 100 is safe and reliable. The lifting platform 4 can enter or exit the opening 11 on the turntable 1 by lifted or lowered by means of the lifting device 5, which facilitates the car to be jacked up and carried by the carrier 7. And the turntable 1 can be rotated by the rotating device 2 to make sure the car to be turned around, thereby the car can be driven to leave easily.
