In a preferred embodiment, the output shaft 51 is disposed laterally; the worm 62 is vertically disposed; the turbine 63 is vertically disposed; wherein, the output shaft 51 arranged horizontally and the worm wheel 63 arranged vertically are respectively positioned at two sides of the worm 62 arranged vertically.

In this embodiment, the turbine 63 is vertically disposed, and the first rotating shaft 64 connected to the turbine 63 is located above the base 40 of the parking space ground lock 100.

It should be noted that, taking the coordinate axes shown in fig. 1 as a reference, "horizontal" means that the planes in the left, right, front and back directions can be regarded as horizontal; "vertical" means that the vertical direction is considered to be vertical. In other words, the direction parallel to the plane of the base 40 of the parking spot ground lock 100 can be regarded as "transverse"; the degree of orientation perpendicular to the base 40 can be considered "vertical".

Due to the fact that the worm 61 and the worm wheel 63 which are vertically arranged are matched, the space occupied by the driving gear 52 and the transmission gear 63 in the vertical direction in the transmission structure is greatly reduced, and the connection in the transverse direction is more compact. In addition, the worm is matched with the design of the transmission gear to output power from the driving unit, so that the transmission structure has the advantage of simple structure.

Further, thanks to the vertical arrangement of the worm 61, the position of the worm wheel 63 engaged with the worm 61 is adjusted downward to be closer to the bottom of the inner cavity 11 of the first bracket 10, so that the first rotating shaft 64 connected with the worm wheel 63 is closer to the bottom of the parking space ground lock 100, which helps to realize the descending of the installation position of the blocking plate 30, and thus the parking space ground lock 100 occupies a smaller space in the vertical direction.

In this embodiment, a plurality of first balls 65 are introduced between the transmission gear 62 and the first support plate 71, similarly to the rotating structure forming a ball bearing, and since no ball bearing is used, there are advantages of small volume and simple structure.

The plurality of second balls 66 are clamped between the lower end surface 611 of the worm 61 and the second support plate 72, so that a gap exists between the lower end surface 611 of the worm 61 and the second side surface 721 of the second support plate 72, that is, the lower end surface 611 of the worm 61 is suspended above the second side surface 721 of the second support plate 72, thereby ensuring smooth rotation of the worm 61 and reducing frictional resistance to rotation of the worm 61.

Wherein the second side 721 is opposite to the lower end 611.

In addition, a plurality of third concave parts are arranged on the lower end surface 611; the second side 721 is provided with a plurality of fourth concave parts; the plurality of third concave parts correspond to the plurality of fourth concave parts one by one; wherein, the plurality of second balls 66 are respectively accommodated in the plurality of third recesses and the plurality of fourth recesses.

As shown in fig. 1, fig. 2, and fig. 7 to fig. 9, another parking space ground lock 100 provided by the present invention includes the transmission structure 60.

The first rotating shaft 64 of the transmission structure 60 is rotatably connected to the first bracket 10, the first bracket 10 is provided with a first shaft hole 12 corresponding to the first rotating shaft 64, and the first rotating shaft 64 is partially rotatably disposed through the first shaft hole 12.

The first shaft 64 extends out of the first shaft hole 12 and is fixedly connected with one side edge of the blocking plate 30, and when the turbine 63 drives the first shaft 64 to rotate, the first shaft 64 drives the blocking plate 30 to lift.

In addition, a first sealing gasket 31 is arranged between one side edge of the blocking plate 30 and the first bracket 10, and the first sealing gasket 31 is fixedly connected with a portion of the first rotating shaft 64 extending out of the first shaft hole 12, so that the phenomenon that water vapor in the external environment enters the cavity 11 of the first bracket 10 from the first shaft hole 12 to cause electrical abnormality is avoided.

Since the baffle plate 30 is turned over on the long side, the center of the first shaft hole 12 and the center of the second shaft hole 21 do not overlap with each other, which means that the center of the first shaft hole 12 and the center of the second shaft hole 21 do not overlap with each other along the long side direction of the baffle plate 30. In another embodiment of the present invention, when the short side of the stopper plate is reversed, the center of the first shaft hole and the center of the second shaft hole do not coincide with each other in the direction of the short side of the stopper plate.

In other words, on the reverse side of the blocking plate 30, the center of the first shaft hole 12 and the center of the second shaft hole 21 do not coincide with each other.

In addition, a first vertical distance from the center of the first shaft hole 12 to the bottom plate 40 is slightly larger than a second vertical distance from the center of the second shaft hole 21 to the bottom plate 40; that is, the center of the first shaft hole 12 is higher than the center of the second shaft hole 21.

The center of the first shaft hole 12 is higher than the center of the second shaft hole 21, and one side of the blocking plate 30 close to the first bracket 10 is slightly higher than one side of the blocking plate 30 close to the second bracket 20.

Further, since the included angles between the central axis 641 of the first rotating shaft 64 and the central axis 81 of the second rotating shaft 80 and the base 40 are the same and are 1.7 °, respectively, and the center of the first shaft hole 12 is higher than the center of the second shaft hole 21, in an actual product, when the blocking plate 30 is lowered to the lowest position, the top surface of the blocking plate 30 is substantially flush with the top of the second bracket 20.
