With the development of the fourth industrial revolution, China's national living standards continue to improve, and small motor vehicles have spread throughout Chinese families. In the community, basically every family has a motor vehicle, and even one family has a motor vehicle. There are two or more motor vehicles, which has caused a serious shortage of parking spaces in the community.

Along with the increasing number of vehicles, in addition to the common ground parking devices in normal life, people have designed many parking devices, such as double-deck or multi-storey parking devices. However, these parking devices still need to occupy a relatively small open space in a community where every inch of land is expensive, and the utilization of space is still relatively insufficient, and the roads in the community are relatively narrow. If the parking device is placed on the narrow driveway It is easy to cause traffic jams in the community. Moreover, the width of the road in the community is not very sufficient, and it is inevitable to adjust the direction when parking or picking up the car, which is a very troublesome thing in a small space.

On the other hand, due to the consideration of environmental factors, a certain amount of lawn greening area must be ensured in the urban community. In order to use the lawn area to solve the problem of insufficient parking spaces in the community, many institutions and individuals have designed a lot of green areas that can be used on the lawn.

The through-hole shaft rotates under the drive of the gear to drive the externally threaded shaft to move up and down, thereby driving the entire device to move up and down. In this way, the transition between the normal state and the working state is completed.

The support device is divided into normal state and working state. The normal state is a simple long seat. The support method is two symmetrically arranged double-column supports at one end and perpendicular to the seat surface. This support can increase the stability of the device. One end is supported by the above-mentioned transmission device, and this end is the fixed end; the so-called double-column support is composed of a fixed part and a sleeve-type part that can be lifted upwards. The plane or steps collide, so it is necessary to shorten a certain distance upwards. The liftable part is driven by the link mechanism to slide upwards. In the working state, the upper and lower plates move relatively, the plate surface expands, and the whole is driven by the lifting device to drop to the designated position. , at this time, the initial transmission device plays a supporting role at one end, the middle part is supported by two shortened cylinders, and the farthest end is supported by the auxiliary plate welded on the upper and lower plates. At this time, the three parts The support provides extremely reliable stability and safety for the device when it is parked.

As shown in Figure 6, the spring 14 and the pedal 15 are a simple power source, and the ratchet mechanism 16 connected to it after the person steps on the pedal 15 will rotate downwards to drive the power input shaft 18. Rotate, pin unclamps pedal 15 and just is bounced reset by spring 14, prepares next time motion, has thus formed the intermittent rotary motion of power input shaft 18, and the gear 24 that is installed on the other end of power input shaft 18 Driven, the driven end conical gear 21 rotates at the same time, and at the same time drives the center gear 1 and 28 below the bevel gear planetary gear train 8 connected to it through the L-shaped shaft 19 to rotate synchronously and drives the planets in the bevel gear planetary gear train 8 The wheel 29 starts to rotate and rotate and drives the T-shaped rocker arm 26 to rotate synchronously with the revolution. The rotation of the rocker arm makes the whole device start to rotate to the inner side of the lawn. 32 rotates, thereby driving the gear 33 to rotate, thereby driving the transmission shaft 11 to rotate, which makes the crank slider mechanism 12 and the connecting rod mechanism 10 start to work at the same time, and the work of the crank slider mechanism 12 pushes the A plate out to the parking area, and the connecting rod The work of the mechanism 10 can make the intermediate support 9 lift up to achieve obstacle avoidance and final support effect.

Thus, the three actions of rotation, descent and extension can be formed simultaneously. The two bench devices are driven separately, and finally the parking surfaces of the two devices are coplanar and parallel. The device can also be reasonably arranged according to the actual situation, so that it can be driven by both feet at the same time to achieve the final effect.

When expanding the parking area while rotating, the whole mechanism is also doing a downward movement. Since there are obstacles similar to steps on the side of the lawn, when the power reaches the transmission shaft 11, it will drive the linkage mechanism 10 to operate, and the linkage can be driven. The raised sleeve 9 slides upwards to cover the cylindrical middle support 5, shortening the entire support device to rotate and avoid obstacles; in the whole inventive device, the device is driven by the rotation of the externally threaded shaft 23 and the internally threaded through-hole shaft 22 The decline of the gear and the rotation of the gear drive the rotation of the device, and the stretching movement of the plate A relative to B under the action of the crank slider mechanism. The three characteristics are carried out simultaneously. The unfolded state is shown in Figure 7. The plate A, B unfolds, the device descends to the lawn surface, the auxiliary support plate 6, the columnar intermediate support 5, the combined support device, and the auxiliary parking plate 7 are on a line to complete the support and parking actions, and the final state is shown in Figure 9.

Wherein, the effect of an inclined plate auxiliary parking plate 7 connected with the lower plate 3 and a vertical plate auxiliary support plate 6 connected with the upper plate 4 is that the inclined plate is just grounded after the device has been lowered, thereby assisting the parking of the car. Easy on and off parking device when picking up the car. The vertical plate just touches the ground after the device has been lowered, so that the supporting function of the auxiliary device can be achieved.

It also includes a protective device, which is composed of a protective cover 2, which protects the transmission device from being affected by the external environment, facilitates maintenance, and increases the life of the entire device.

The method of using the parking device provided by the present invention is as follows: firstly, the present invention acts as a long seat and places it next to the lawn for people to have a rest during the day, and at night, the parking device is opened to the designated working position by the staff stepping on it. As shown in Figure 8, the device moves towards the working area and finally arrives at the designated position. The driver drives the car from the road to the parking device via the auxiliary slope 6 to complete the parking. When the vehicle is parked, after the car is poured out of the parking device backwards from the device, the ratchet mechanism 16 is reversely rotated through the rotation reversing mechanism 17 of the staff again, and the parking device is returned to the most initial common long seat state.
