RU186497U1 - PASSENGER CAR DOOR DOOR - Google Patents

Abstract

The utility model relates to the field of transport engineering, namely to the design of the tailgate of a car. The tailgate door consists of the outer and inner panels (1, 2), where, from the bottom of the inner panel, by means of welding, a bracket (4) is installed for fastening the door lock, which has a connector (5) made in the form of a horizontal angular protrusion, through which the bracket for fastening the door lock is connected with an external panel (1) by spot welding, and the bracket (4) is U-shaped and installed with its vertical generators on the sides of the technological hole (3), whose height is 2/3 of the height of the lower part of the inner panel ate. The technical result is to create a rigid connection between the door panels and the unification of the node for different types of locks.

Description

The utility model relates to the field of transport engineering, namely to the design of the tailgate of a car.

The closest technical solution to the claimed design is the rear of the car ("Catalog of parts and assembly units of cars LADA KALINA 2192, 2194 and their modifications", JSC NVP "ITC AUTO", Tolyatti, 2013, M390, p. 258) comprising an outer and an inner door panel, where a door lock bracket is mounted on the bottom of the inner panel by welding. In this design, there is no rigid connection between the lock fastening zone and the outer panel, which would close the cross-section and, as a result, the risks for the durability of the lock fastening zone on the tailgate increase, and only one type of lock can be installed in this design.

The objective of the utility model is to strengthen the rigid connection between the door panels, which leads to reinforcement of the tailgate and unification of the door for different types of locks.

To solve this problem, a tail door design is proposed, consisting of an outer and an inner panel, where a door lock fastening bracket is installed through the bottom of the inner panel, which has a connector made in the form of a horizontal angular protrusion, through which the door lock fastening bracket is connected to the point external panel welding, and the bracket has a U-shape and is installed with its vertical generators on the sides of the technological hole, the height of which stavlyaet 2/3 of the height of the inner bottom panel.

Comparison of the claimed technical solution with the prior art in scientific, technical and patent documentation as of the priority date in the main and related sections shows that the set of essential features of the claimed solution was not known - therefore, it meets the patentability condition of “novelty”.

The proposed technical solution is industrially applicable, because can be manufactured industrially, efficiently, reproducibly, therefore, meets the patentability condition “industrial applicability”.

The essence of the technical solution is illustrated in the drawings.

The tailgate of a passenger car includes an outer panel (1) and an inner panel (2). In the central part, below the inner panel, a large technological hole (3) is made with a quadrangular contour and a radial rounding of corner transitions, and the height of which extends beyond the middle of the lower part of the panel (from the bottom to the window-sill), that is, the height is about 2/3 of the height of the lower parts. The increased size of the technological hole (3) allows you to reduce the weight of the door, and also allows you to freely install an electric drive for the second type of lock after assembling the door. Bottom of the hole (3), on its lateral sides there is a bracket (4) for fastening the door lock, which has a three-dimensional U-shape, where the horizontal generatrix is a connector (5) and is made in the form of an angular protrusion. The bracket (4) is mounted so that the vertical generators are spot-welded to the sides of the technological hole (3), and the connector (5) of the bracket (4) is also spot-welded to the outer door panel (1), thereby closing the contour of the panels (1 , 2) and forming a rigid connection between the panels (1, 2). The connector (5) of the door lock bracket (4) is also a stiffener for the process hole (3).

To place the second type of lock on the tailgate from the inside (from the passenger compartment) of the inner panel (2), a bracket (6) for fastening the door drive is installed. The bracket (6) is made in the form of a three-beam part with mounting pads (7.8), one (7) of which is located in the center of the beams, and the other three (8) at their ends with the formation of supporting "legs". On the inner panel (2) and on the mounting pads of the “paws”, holes were made for bolting the bracket (6) to the panel (2), which allows mounting the bracket (6) and the door drive already on the vehicle assembly.

Claims (5)

1. The tailgate of a passenger car, consisting of external and internal panels, where in the lower part, on the external side of the internal panel, a door lock fastening bracket is installed, characterized in that the door lock fastening bracket is made in a U-shape and has a connector made in in the form of a horizontal angular protrusion, by means of which the bracket for fastening the door lock is connected to the outer panel by spot welding, the bracket being installed with its vertical generators on the sides hole, the height of which is 2/3 of the height of the lower part of the inner panel. 2. The tailgate of a car according to claim 1, characterized in that the bracket for attaching the door lock is connected to the inner panel by spot welding. 3. The tailgate of a car according to claim 1, characterized in that a door drive mounting bracket is mounted on the inside of the inner panel. 4. The tailgate of a passenger car according to claim 1, characterized in that the door drive mounting bracket is made in the form of a three-beam part with mounting pads in the center and at the ends of the beams. 5. The tailgate of a car according to claim 1, characterized in that the fixing of the door drive mounting bracket on the inner panel is made by means of a bolted connection.
