Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] like Figure 1-3As shown, the present application discloses a door guard protection structure, including a protection component 2, which is installed on the inner side of a gate machine body 1, and the protection component 2 includes a second door body 210, a rotating shaft 212 is installed on the hypotenuse of the second door body 210, a first gear 213 is installed on the outer side of the middle part of the rotating shaft 212, a chain 214 is installed on the outer side of the first gear 213, a second gear 215 is installed on the inner side of the other end of the chain 214, a rack 216 is installed on the outer side of the second gear 215 near the other end, a damper 217 is installed on the upper end of the rack 216, and a second spring 218 is arranged between the outer side of the telescopic end of the damper 217 and the rack 216;

[0021] When the vehicle hits the second door body 210 , the second door body 210 rotates through the rotating shaft 212 , and at the same time the first gear 213 drives the second gear 215 to rotate through the chain 214 , and the second gear 215 compresses the damper 217 through the rack 216 to buffer the force hitting the second door body 210 .

[0022] like Figure 1-2 As shown, the protection component 2 also includes a mounting frame 201, a motor 206 is installed at the upper end of the mounting frame 201, a rotating rod 207 is installed at the output end of the motor 206, a first door body 208 is installed on the outer side of the rotating rod 207, and the first door body 208 is movably connected to the rotating shaft 212, and three sleeves 202 are installed at the rear end of the mounting frame 201, a short rod 203 is installed on the inner side of the sleeve 202 near the rear end, and a mounting block 204 is installed at the rear end of the short rod 203, and a first spring 205 is sleeved on the outer side of the short rod 203 in the center and located between the sleeve 202 and the mounting block 204. The motor 206 drives the rotating rod 207 to open the first door body 208. When a pedestrian hits the first door body 208, the sleeve 202 moves backward along the direction of the short rod 203 to reduce the force of the pedestrian hitting the first door body 208, and the first spring 205 can drive the sleeve 202 to reset.

[0023] like Figure 1-2 As shown, a collision-proof plate 211 is installed at the front end of the second door body 210. A plurality of through holes are opened on the collision-proof plate 211. The collision-proof plate 211 is connected to the second door body 210 through a support column. By arranging the collision-proof plate 211 at the front end of the second door body 210, buffering can be performed when a vehicle collides with the second door body 210.

[0024] like Figure 1-2As shown, the first door body 208 and the second door body 210 are both designed in the shape of a right triangle. An anti-collision strip 209 is installed at the top of the front end of the first door body 208. The front end of the anti-collision strip 209 is designed in an arc shape, and the inner side of the anti-collision strip 209 is designed in a hollow shape. The hypotenuse of the first door body 208 is provided with an arc edge. By setting the internal hollowness, the anti-collision strip 209 with an arc shape at the front can buffer when a pedestrian hits the first door body 208. The arc design of the hypotenuse of the first door body 208 can provide protection when a pedestrian hits the first door body 208.

[0025] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings.

The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0027] The implementation principle of a door access protection structure in the embodiment of the present application is:

[0028] When in use, when a pedestrian hits the first door body 208, the anti-collision strip 209 contacts the human body for buffering, and the first door body 208 moves backward along the direction of the short rod 203 along with the mounting frame 201 and the sleeve 202, thereby buffering. After the human body moves away from the first door body 208, the first spring 205 drives the first door body 208 to reset. When the tire of the vehicle hits the second door body 210, the anti-collision plate 211 provides protection. At the same time, the second door body 210 rotates through the rotating shaft 212, and the first gear 213 is driven to rotate during rotation. The first gear 213 drives the second gear 215 to rotate through the chain 214, and the second gear 215 drives the rack 216 to move. The rack 216 pushes the telescopic rod of the damper 217 for buffering. After the impact disappears, the second spring 218 cooperates with the rack 216, the second gear 215, the chain 214, the first gear 213 and the rotating shaft 212 to drive the second door body 210 to reset.
