Description

Connectors for cars

technical field

The utility model relates to a connection device, in particular to a connection device for automobiles.

Background technique

At present, with the increasing popularization of science and technology, various mechanical devices are changing people's daily life, among which the automobile is the most typical, as the automobile as a means of transportation has been inseparable from human life. At the same time, the safety performance of a car represents the level distinction of a car. The higher the safety performance, the higher the grade of the car. The spherical connection device is an important component of the car, mainly used to connect two mechanisms, and after the connection, the mechanism with the ball head connected to the connection device can be freely rotated in the spherical connection device. Take the rear door support connection system of a high-end multi-purpose vehicle (MPV) as an example. When the driver and passengers go to the trunk to load and unload goods, the driver and passengers must operate the rear door, and there are drivers and passengers entering and exiting the trunk position. It is necessary to keep the back door stable during the process of fully opening or opening and closing, so as not to cause casualties and property damage due to the back door falling off. Therefore, considering the safety of users, the stability of the spherical connection device is very important. It is particularly important that the spherical connection device is not allowed to fall off and break when the door is in the fully open position and during operation, so as to keep the door stable. As shown in Figure 4, the existing connecting device for automobiles includes a mounting base 5, and the mounting base 5 is provided with a groove 5a for loading the ball joint 2. When installing, the ball joint 2 is inserted into the groove 5a, The effect of fixing the ball joint is achieved by the ball joint 2 squeezing the outer edge of the groove 5a to reduce the inner hole. However, the disadvantages of the existing connecting devices for automobiles are: 1. The groove material of the mounting seat is relatively soft, which limits the load-carrying capacity of the device; 2. The groove material of the mounting seat is relatively soft, making the ball head of the ball joint Rotation wear resistance is poor in the groove; 3. Difficult to assemble, the spherical joint is installed in the groove of the spherical mounting seat and then squeezes the outer edge of the spherical groove to deform it. This process requires large-scale equipment to implement; 4. Mass production Stability is difficult to guarantee in this case.

The axis line of the positioning hole is on the same straight line, and the axis line of the positioning hole is perpendicular to the axis line of the via hole. A U-shaped circlip is inserted into the ball socket through the via hole on one side wall of the ball socket. The U The two ends of the circlip fall into the positioning holes on the other side wall of the ball socket respectively, and the positioning is formed through the positioning holes.

The connecting seat is made of metal or plastic.

The two ends of the U-shaped circlip are respectively provided with positioning parts extending horizontally to the two sides of the U-shaped circlip after being folded, and the locating parts at both ends of the U-shaped circlip respectively fall into the corresponding positioning holes to form positioning.

The length of the positioning portion is smaller than the axial length of the positioning hole.

Adopt the above-mentioned technical scheme: since the connecting seat of the utility model is provided with a ball socket for installing a spherical joint, two via holes for the U-shaped retaining spring to pass are symmetrically provided on the side wall near the mouth end of the ball socket. The axis lines of the through holes are parallel, and two positioning holes for positioning the U-shaped circlip are symmetrically arranged on the other side wall near the mouth of the ball socket. The axis lines of the two positioning holes are on the same straight line, and the positioning holes The axis line is perpendicular to the axis line of the via hole. A U-shaped circlip is inserted into the ball socket through the via hole on one side wall of the ball socket. The two ends of the U-shaped circlip fall into the other side of the ball socket respectively. In the positioning hole on the wall, the positioning is formed through the positioning hole, so that when assembling, it is only necessary to insert the ball joint into the ball socket of the connecting seat, and then insert the U-shaped circlip into the ball socket along the through hole on the side wall of the ball socket After the U-shaped circlip is inserted in place, the two ends of the U-shaped circlip fall into the positioning holes on the other side of the ball socket for positioning, so that the utility model can use the U-shaped circlip to lock the spherical joint in the connection In the ball socket of the seat, the assembly of the connection seat and the ball joint is completed. The whole assembly process is simple, fast and convenient, and the locking effect is good, which can effectively prevent the ball joint and the connection seat from being stuck and falling off. When it needs to be disassembled, it is only necessary to make the connecting seat in a loose state, pull out the U-shaped retaining spring, and then take out the ball joint from the ball socket, which is highly detachable and can be disassembled and used repeatedly.

The utility model is used for the connecting device of the automobile, which can not only improve the bearing capacity of the overall structure, but also enhance the wear resistance of the spherical joint in the ball socket, so as to improve the service life of the spherical connecting device; it also reduces the technical difficulty of installation, and can Repeated disassembly and utilization saves product cost. Compared with the existing spherical connection device, the utility model does not need to use extrusion technology when assembling, and only needs to insert U-shaped clip springs, making its assembly and disassembly easier. It is simple and easy; at the same time, the utility model realizes the connection function by locking the spherical joint laterally with a U-shaped circlip, which can not only ensure the free rotation of the spherical joint, but also prevent the spherical joint from falling off, thereby improving safety.
