DETAILED DESCRIPTION

[0028] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0029] See also Figures 1 to 7 Now, a door limiter structure for preventing door opening accident provided by the utility model is described. A door limiter structure for preventing door opening killing comprises a limiter cylinder 200 installed on the door and a limiter arm 100 connected to the frame on the vehicle; a through hole 210 is horizontally opened in the middle of the limiter cylinder 200, the limiter arm 100 passes through the through hole 210, and the upper and lower end surfaces of the limiter arm 100 are relatively provided with protrusions 121, and the upper and lower end surfaces of the limiter cylinder 200 are respectively relatively provided with installation chambers 220 connected to the through hole 210, and the installation chamber 220 is provided with an elastic member 240 and a top pressure member, and the elastic member 240 presses the top pressure member against the upper end surface or the lower end surface of the limiter arm 100; the upper and lower parts of the limiter cylinder 200 are provided with a locking motor 310 and a locking block 320, and the locking motor 310 drives the locking block 320 to rotate to lock or unlock the freedom of the top pressure member to move axially along the installation chamber 220.

[0030] The utility model provides a door limiter structure for preventing door opening accident. Compared with the prior art, the limiter cylinder 200 is fixed on the door by at least two assembly connecting bolts 400, and the limiter arm 100 is installed on the frame on the vehicle. The limiter arm 100 passes through the through hole 210 of the limiter cylinder 200, and the two elastic members 240 in the limiter cylinder 200 provide elastic force to the two top pressure members respectively, so that the two top pressure members are relatively pressed against the upper end face and the lower end face of the limiter arm 100. The locking motor 310 drives the locking block 320 to rotate. As the locking block 320 rotates, the locking block 320 can lock or unlock the movement of the top pressure member along the installation chamber 220. When no pedestrian is found on the side of the vehicle, the top pressing piece is in an unlocked state. When the two top pressing pieces pass through the protrusions 121 arranged opposite to each other on the upper and lower end surfaces of the limiter arm 100, the protrusions 121 squeeze the two top pressing pieces so that they move back to back. The top pressing piece passes over the protrusions 121, so that the door can be opened normally. When a pedestrian is found on the side of the vehicle, the top pressing piece is in a locked state. The top pressing piece cannot move relatively along the installation cavity 220. The top pressing piece will block the protrusions 121, so that the door cannot be opened, avoiding the occurrence of the door opening killing situation.

[0031] See also Figure 1 The limiter arm 100 includes a base 110 and an extension arm. The base 110 is connected to the frame on the vehicle. One end of the extension arm is hinged to the base 110 and passes through the through hole 210. The protrusion 121 is relatively arranged to limit the door from being opened to the maximum angle in an instant. Only when force is continuously applied to the door can it be opened to the maximum angle.

[0032] Specifically, one side of the base 110 has two mounting holes, and the base 110 is connected to the vehicle frame by bolts through the two mounting holes. The other side of the base 110 has two coaxial hinge holes, one end of the extension arm is located between the two hinge holes, and a long foot bolt is used to penetrate the two hinge holes and the end of the extension arm and is locked with a nut. During the opening or closing process of the door, the hinge structure between the base 110 and the extension arm can rotate in accordance with the change of the door angle to ensure smooth opening and closing of the door.

[0033] In addition, the extension arm has a certain curvature. During the door opening process, the extension arm is gradually pulled outward along the through hole 210. The curvature of the extension arm can also match the rotation angle of the door, thereby reducing the possibility of the extension arm getting stuck in the through hole 210.

[0034] There are multiple raised portions 121 spaced apart along the length direction of the extension arm. When the door is opened, the two pressing members can pass through the multiple raised portions 121 in sequence to be opened smoothly. Each time the pressing members pass through the raised portion 121, it is equivalent to forming a damping effect on the door opening, which limits the door from being opened to the maximum angle in an instant. Only by continuously applying force to the door can it be opened to the maximum angle, which can avoid the problem of door opening failure caused by sudden door opening.

[0035] See also Figure 3 The extension arm includes an elastic arm 120 and a rigid arm 130 . The rigid arm 130 is arranged inside the elastic arm 120 along the length direction. Both the elastic arm 120 and the rigid arm 130 are hinged to the base 110 . The protrusion 121 is arranged on the upper end surface and the lower end surface of the elastic arm 120 .

[0036] Specifically, the elastic arm 120 is made of rubber material, and the rigid arm 130 is made of metal material. A receiving cavity is provided inside the elastic arm 120, and an opening is provided at one end of the receiving cavity away from the base 110. The rigid arm 130 is inserted into the receiving cavity through the opening, and the long foot bolt passes through the elastic arm 120 and the rigid arm 130 at the same time, so as to realize hinged cooperation with the base 110 at the same time. The raised portion 121 is integrally formed on the upper end surface and the lower end surface of the elastic arm 120.

[0037] See also Figure 1 and Figure 3 An anti-slip portion 131 is provided at one end of the rigid arm 130 away from the base 110. The anti-slip portion 131 is located outside the opening of the elastic arm 120. The anti-slip portion 131 is a plate body integrally formed on the rigid arm 130. The width of the plate body is greater than the width of the through hole 210. When the car door is opened to the maximum angle, the plate body abuts against the outer side of the through hole 210 to prevent the rigid arm 130 from detaching from the through hole 210.

[0038] See also Figure 6 and Figure 7 The top pressure piece includes a top block 260 and a connecting sleeve 250. The top block 260 is arranged on the side of the connecting sleeve 250 close to the through hole 210. The end of the top block 260 abuts against the upper end surface or the lower end surface of the elastic arm 120. The two are integrally formed. The elastic member 240 is located in the connecting sleeve 250 and applies an elastic force to the connecting sleeve 250 to move toward the through hole 210.

[0039] Specifically, the end of the top block 260 is an arc protrusion. Similarly, the end of the protrusion 121 is also an arc protrusion. Arc surfaces are formed on both sides of the arc protrusion. When the limiter arm 100 drives the protrusion 121 to laterally squeeze the top block 260, the force is applied to the two arc surfaces, thereby forming a component force that pushes the top block 260 upward, so that the two pressing parts can pass through the protrusion 121 smoothly.

[0040] See also Figure 4 The outer wall of the connecting sleeve 250 is provided with a guide column 252, which is coaxially arranged with the connecting sleeve 250. The inner wall of the installation chamber 220 is provided with a guide groove adapted to slide with the guide column 252 to prevent the connecting sleeve 250 from rotating in the installation chamber 220.

[0041] See also Figure 6 and Figure 7 The upper and lower parts of the side wall of the limiter cylinder 200 are provided with a receiving hole 280 connected to the installation chamber 220, and a limiting bayonet 253 is provided on the side of the connecting sleeve 250 close to the receiving hole 280. The locking block 320 is rotatably arranged in the receiving hole 280 and the edge of the locking block 320 is located in the limiting bayonet 253. The edge of the locking block 320 is provided with a clearance notch 321 for avoiding the limiting bayonet 253. The locking block 320 is a disc structure, and a small semicircular area smaller than the outer diameter of the disc is longitudinally removed from one side of the disc structure, so as to form a clearance notch 321 on the disc structure. When the locking motor 310 drives the locking block 320 to rotate, the edge of the locking block 320 is located in the limiting bayonet 253, and the edge of the locking block 320 can block the connecting sleeve 250 from moving along the axial direction of the installation chamber 220 to form a locked state. When the locking block 320 is driven by the locking motor 310 to rotate until the clearance gap 321 is opposite to the limiting bayonet 253, the clearance gap 321 can avoid the connecting sleeve 250, and the connecting sleeve 250 can move axially along the installation chamber 220 to form an unlocked state.

[0042] In addition, the upper and lower parts of the side wall of the limiter cylinder 200 are provided with an adapter groove 270 connected to the receiving hole 280, the locking motor 310 is installed in the adapter groove 270, and the driving end of the locking motor 310 extends into the receiving hole 280 to connect the locking block 320, and the outside of the adapter groove 270 is provided with a fixing bracket 290 for fixing the locking motor 310 in the adapter groove 270. The depth of the adapter groove 270 is less than the thickness of the locking motor 310, the locking motor 310 is arranged in the adapter groove 270, and the locking motor 310 partially protrudes from the side wall of the limiter cylinder 200. The fixing bracket 290 is a U-shaped frame, and the two sides are fixed to the side wall of the limiter cylinder 200 by screws, and the inside is buckled on the outer periphery of the locking motor 310, so as to achieve the fixing of the locking motor 310. The driving end of the lower portion of the locking motor 310 is connected to the locking block 320 to drive the locking block to rotate in the receiving hole 280 .

[0043] Based on the same inventive concept, the utility model also provides a vehicle, including a vehicle-mounted radar and the above-mentioned door limiter structure for preventing door opening, wherein the vehicle-mounted radar detects information of side vehicles and pedestrians to control the action of the locking motor 310 through the vehicle-mounted computer.

[0044] When the on-board radar detects that there are no pedestrians or vehicles on the side, a signal is sent to the locking motor 310 through the on-board computer, and the locking motor 310 drives the locking block 320 to be in an unlocked state, so the door can be opened normally; when the on-board radar detects that there are pedestrians or vehicles on the side, a signal is sent to the locking motor 310 through the on-board computer, and the locking motor 310 drives the locking block 320 to be in a locked state, so the door cannot be opened, thereby preventing the driver or passengers from suddenly opening the door and causing a door-opening kill situation.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
