Technical Field

[0001] The invention relates to the field of parking equipment, and in particular to a semi-self-locking structure used in parking equipment. Background Art

[0002] There are two types of anti-collision or protection structures of parking locks on the market. One is to add a clutch at the output end; the other is to self-lock when the baffle rises into place. For parking locks with a clutch structure, when a vehicle is forced out, the baffle is forced down, the system sounds an alarm, and the vehicle successfully drives out, and the purpose of blocking the vehicle is not achieved; parking locks with a self-locking baffle when the baffle rises into place cannot self-lock when the baffle is not in place due to the various heights of the vehicle chassis. At this time, when a vehicle is forced out, its prime mover will be damaged. Summary of the invention

[0005] Furthermore, the outer contour of the pulling block in contact with the roller is an inclined surface, so as to facilitate the lifting and lowering of the roller.

[0006] Furthermore, the roller bracket shaft is respectively connected to the roller bracket and the torque transmission sleeve through a torque transmission key, and the torque transmission sleeve is connected to the baffle plate shaft through a key transmission connection.

[0007] Furthermore, the baffle plate shaft is welded to one side of the baffle plate.

[0008] Furthermore, the electric push rod assembly is connected to the pull block via a connecting pin.

[0009] Furthermore, the pull block is slidably installed in the guide groove of the shell.

[0010] Furthermore, both ends of the roller bracket shaft are rotatably connected to the two side panels of the shell.

[0011] The beneficial effects of the present invention are: The structure of the present invention can enable the vehicle baffle to withstand the impact of a vehicle driving out forcefully within a certain height range without damaging the driving part. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0015] like Figures 1 to 3 As shown, a semi-self-locking structure used in a car-blocking device comprises a shell 1, in which an electric push rod assembly 2 is arranged, characterized in that a rod head 3 of the electric push rod assembly 2 is connected to and drives a pulling block 5, a roller bracket shaft 6 is arranged above the pulling block 5, the roller bracket shaft 6 is connected to and drives a roller bracket 8 and a car-blocking plate shaft 12, the car-blocking plate shaft 12 is connected to and drives a car-blocking plate 13, one end of the roller bracket 8 is rotatably connected to a roller 10 via a fixing pin 9, in this embodiment, the fixing pin 9 is welded to the roller bracket 8 as a whole, and the roller 10 rolls and falls on the outer contour of the pulling block 5, so that the roller bracket 8, the roller bracket shaft 6, the car-blocking plate shaft 12 and the car-blocking plate 13 rotate around the axis of the roller bracket shaft 6 under the push of the pulling block 5, thereby blocking / releasing the vehicle by raising or lowering the car-blocking plate 13 through rotation.

[0016] The outer contour of the pulling block 5 in contact with the roller 10 is an inclined surface, so as to facilitate the lifting and lowering of the roller 10.

[0017] The roller bracket shaft 6 is respectively connected to the roller bracket 8 and the torque transmission sleeve 11 through the torque transmission key 7, and the torque transmission sleeve 11 is connected to the baffle plate shaft 12 through the key transmission.

[0018] The baffle plate shaft 12 is welded to one side of the baffle plate 13 .

[0019] The electric push rod assembly 2 is connected to the pull block 5 via a connecting pin 4 .

[0020] The pull block 5 is slidably installed in the guide groove of the housing 1 .

[0021] Both ends of the roller bracket shaft 6 are rotatably connected to the two side panels of the housing 1 .

[0022] Action process and principle of the present invention In the present invention, when the electric push rod assembly 2 pushes the rod head 3 out, the pull block 5 connected to the rod head 3 through the connecting pin 4 also moves forward, so that the roller 10 is located on the inclined surface of the pull block 5, as shown in FIG. Figure 2 As shown, the roller 10 drives the roller bracket 8 to rotate, and then drives the roller bracket shaft 6, the torque transmission sleeve 11, the baffle shaft 12 and the baffle 13 welded on the baffle shaft 12 to rise through the torque transmission key 7; due to the existence of the inclined surface of the pull block 5, as long as the roller 10 is located on the inclined surface of the pull block 5 and the highest plane, the baffle assembly can withstand the forced impact of the vehicle within a certain height range without damaging the prime mover; only the angle of the inclined surface of the pull block 5 and the height of the inclined surface need to be adjusted to achieve the adjustment of the lifting height range of the baffle 13, and a semi-self-locking state can be achieved.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations.
