Description

Car door self-limiting structure Technical Field The utility model relates to the field of vehicle doors, in particular to a vehicle door self-limiting structure. Background The door hinge is mainly used for connecting the door and the vehicle body, ensuring the smooth opening and closing of the door, supporting the door, providing structural strength, reducing noise, maintaining and the like. In order to avoid collision between the vehicle door and the vehicle body, the conventional vehicle door is arranged into an upper door hinge and a lower door hinge, and a vehicle door limiter is arranged at a position between the two hinges, but the cost of the independent vehicle door limiter is high, and the installation of the limiter is difficult due to the structure of part of the vehicle body and the vehicle door. The automobile door hinge structure cab with the limiting function and the automobile disclosed in the patent number CN219012280U are shown, and the automobile door hinge structure cab with the limiting function comprises a hinge assembly and a limiting assembly, wherein the hinge assembly is arranged on an automobile door of the cab and an automobile body and comprises a mounting plate I, a mounting plate II and a connecting shaft, the limiting assembly is fixed on the hinge assembly through bolts, and the limiting assembly comprises a limiting rod and a limiting clamping groove. When the car door is opened to a certain angle, the limiting rod enters the limiting clamping groove, and the magnet in the limiting clamping groove fixes the limiting rod, so that the limiting function of the car door is realized. The limiting assembly can limit the vehicle door and keep the opening angle, but the contact between the limiting rod and the side wall of the limiting clamping groove is rigid contact, when the force for opening the vehicle door is large, the limiting rod is easy to collide with the limiting clamping groove, so that the limiting rod is deformed or even damaged, and the limiting effect is lost. Disclosure of utility model The utility model aims to provide a self-limiting structure of a vehicle door, which aims to solve the problem that the limiting structure is in rigid contact and is easy to damage under the action of large force. The self-limiting structure of the vehicle door comprises a hinge assembly and a limiting assembly, wherein the hinge assembly comprises a female hinge and a male hinge, the female hinge is hinged with the male hinge, the male hinge is U-shaped, the top and the bottom of the male hinge are opposite to the female hinge, the limiting assembly comprises a spring piece and a clamping plate, the spring piece is arranged on the male hinge, one end, away from the female hinge, of the spring piece is an elastic part and can elastically deform towards one side, close to the side wall of the male hinge, of the spring piece, and the clamping plate is arranged on the female hinge and can be clamped with the spring piece. The beneficial effect of this scheme is: The spacing subassembly in this scheme can replace the door stopper in traditional door arrangement to carry out spacing and keep open the state to the door, and compares with current spacing subassembly, spring leaf in this scheme can take place elastic deformation to open at the door behind the angle of predetermineeing, the non-rigid contact of contact between spring leaf and the cardboard, so when opening the door, spring leaf and cardboard can not damage because of powerful striking. Secondly, spacing subassembly in this scheme is spring leaf and cardboard, and both are platelike structure, and easy cleanness in the use can not pile up dust, silt etc. and be difficult to the clearance like bucket-shaped structure general inboard. Finally, the limit of the vehicle door is realized through the cooperation between the spring piece and the clamping plate in the scheme, other structures are not required to be fixed on the spring piece or the clamping plate, and the limit assembly is simple in processing and low in cost. Further, the spring piece includes installation department and joint portion, and installation department and male hinge connection, and joint position are located one side that the installation department kept away from the female hinge, and are equipped with the arch on the joint portion, are equipped with on the cardboard can with protruding complex draw-in groove. The automobile door limiting device has the beneficial effects that the automobile door can be automatically limited through the matching of the protrusions and the clamping grooves, and the structure is simple. Further, the bulges are V-shaped structures formed by bending the plate. The clamping part can be rapidly machined through stamping, and the manufacturing cost is further reduced. And when spacing the door, the opening both ends of joint portion all offset with the male hinge, and V-arrangement structure can keep bigger intensity this mo
