[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] A three-dimensional parking device, referring to Figure 1 , Figure 2 , comprising a rack 1, a lifting platform 2 and a driving mechanism, two connecting frames 3 are connected to the rack 1 through hinges, the hinge shafts of the two connecting frames 3 are horizontally arranged and parallel to each other, the lifting platform 2 is horizontally arranged at one end of the two connecting frames 3 away from the rack 1, and the two connecting frames 3 are hinged to the lifting platform 2, the frame surfaces of the two connecting frames 3 are parallel, the driving mechanism comprises a motor 4 and a transmission mechanism, the transmission mechanism is a self-locking worm gear reducer 5, the transmission mechanism is located on the rack 1, the output shaft of the motor 4 is connected to the worm end of the transmission mechanism, the wheel shaft of the turbine end of the transmission mechanism is parallel to the hinge shaft of the connecting frame 3 and is connected with a drive rod 6, a guide rod 7 is arranged on the connecting frame 3 close to the drive rod 6, the guide rod 7 is parallel to the frame surface of the connecting frame 3, a sliding block 8 is slidably arranged on the guide rod 7 along the length direction of the guide rod 7, and one end of the drive rod 6 away from the wheel shaft of the turbine end is hingedly connected with the sliding block 8. Among them, the lengths of the two connecting frames 3 between the lifting platform 2 and the rack 1 are the same, the lifting platform 2, the two connecting frames 3 and the rack 1 form a parallelogram structure, so that the lifting platform 2 is always parallel to the ground.

[0024] In the self-locking worm gear reducer 5, the shape of the worm is similar to that of a screw, and the helical surface is closely meshed with the gear surface of the worm wheel. When the worm shaft rotates, the inclined teeth of the helical surface will drive the teeth of the worm wheel to move in mesh, so that the worm wheel rotates along the axis perpendicular to the worm. This screw transmission mechanism effectively converts the input high speed into low speed of the worm wheel, realizing the function of speed reduction.

[0025] The self-locking principle of the worm gear reducer is based on friction transmission and self-locking. There is a large sliding friction force between the contact surface of the worm and the worm gear. This friction force not only transmits power, but also gives the worm gear reducer a unique self-locking property. When the lead angle of the worm (i.e. the inclination angle of the thread) is less than the friction angle of the contact surface between the worm and the worm gear, the worm will not be able to drive the worm gear in the opposite direction, i.e. only the worm is allowed to rotate the worm gear. Then in this scheme, the self-locking principle of the self-locking worm gear reducer 5 can prevent the lifting platform 2 from descending without being driven by the motor 4.

[0026] In this scheme, the three-dimensional parking device is installed on the ground in an area with a small site area. The motor 4 and the transmission mechanism drive the driving rod 6 to rotate downward. The driving rod 6 can drive the sliding block 8 to slide on the guide rod 7 during rotation. The sliding block 8 can push the guide rod 7 to rotate downward during sliding downward on the guide rod 7, thereby causing the two connecting frames 3 to rotate downward, causing the lifting platform 2 to descend to a height close to the ground. At this time, the vehicle is driven and parked on the lifting platform 2. Then the motor 4 is reversed to cause the two connecting frames 3 to drive the lifting platform 2 to rise, thereby causing the vehicle to be parked away from the ground. Since the total floor area occupied by the rack 1 is less than the total floor area occupied by the vehicle parked on the ground (i.e. the area of the lifting platform 2 covering the ground is greater than the area of the rack 1 covering the ground), the occupation of the ground space resources by the vehicle is reduced. Moreover, the device structure of the utility model is relatively simple, and the cost is relatively low.

[0027] Specifically, the guide rod 7 is provided with a sliding groove 9 along the length direction of the guide rod 7. The sliding block 8 is located in the sliding groove 9 and is in sliding cooperation with the sliding groove 9. The cross-sectional shape of the sliding block 8 and the sliding groove 9 is inverted T-shaped, so that the sliding block 8 can always slide along the sliding groove 9 of the guide rod 7.

[0028] Embodiment 2

[0029] On the basis of embodiment 1, in this embodiment, referring to Figure 1 、 Figure 2 , the rack 1 is provided with a support rod 10. The top of the support rod 10 is provided with a mounting bracket 11. The mounting bracket 11 is covered with a sunshade cloth 12. The lifting platform 2 can be raised to below the sunshade cloth 12 after the two connecting frames 3 are rotated. The sunshade cloth 12 is used for shielding and protecting the vehicle on the lifting platform 2. The sunshade cloth 12 further extends downward to the ground around the sunshade cloth 12, which is used for surrounding and protecting the vehicle.

[0030] In this scheme, after the vehicle is parked on the lifting platform 2, the lifting platform 2 is raised with the rotation of the connecting frame 3, and the lifting platform 2 sends the vehicle upward to below the sunshade cloth 12. The sunshade cloth 12 can shade the vehicle, and the sunshade cloth 12 can also dustproof the vehicle, which is beneficial to reduce the accumulation of impurities such as leaves and dust on the vehicle.

[0031] Furthermore, a diagonal brace 13 is provided on the support rod 10. One end of the diagonal brace 13 is connected to the support rod 10, and the other end extends upward at an incline and is connected to the mounting frame 11. The diagonal brace 13 helps to improve the stability of the mounting frame 11 on the support rod 10.

[0032] Example 3

[0033] Based on Example 1, in this example, refer to Figure 2 , Figure 3 The lifting platform 2 has arched protrusions 14 at both ends along the vehicle's entry and exit direction. Vehicles are parked in the area between these arched protrusions 14. By providing arched protrusions 14 at both the front and rear ends of the lifting platform 2, drivers can easily determine if the vehicle is fully parked on the platform by observing the bumps caused by the rear tires passing over the rear arched protrusion 14. The arched protrusion 14 at the front of the lifting platform 2 helps prevent the front tires from easily veering off the platform. Specifically, when parking, the vehicle first passes over the arched protrusion 14 at the rear end of the lifting platform 2, and then over the arched protrusion 14 at the front end.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
