It should be noted that, in the case of no conflict, the embodiments and features of the embodiments of the present invention may be combined with each other. For convenience of description, the words "upper", "lower", "left" and "right" in the following description are used only to indicate the correspondence with the upper, lower, left and right directions of the drawings, and do not limit the structure.

As shown in fig. 1, the connection device of a target vehicle according to this embodiment includes an upper frame 1, a mounting base 2, a locking assembly 3, and a screw rod 4.

The mounting base 2 comprises two first cross rods 21 arranged at intervals and a first longitudinal rod 22 connected between the end parts of the two first cross rods 21. The closed frame mouth shape is maintained by the two first cross bars 21 and the two first longitudinal bars 22. The mounting base 2 may be used as a chassis for a target vehicle.

The upper frame 1 comprises two second cross rods 11 arranged at intervals, second longitudinal rods 12 connected between the end parts of the two second cross rods 11 and third cross rods 13 arranged between the two second cross rods 11, the third cross rods 13 are connected with the two second longitudinal rods 12, and two third longitudinal rods 14 are arranged between the third cross rods 13 and the second cross rods 11. Four third vertical rods 14 are respectively provided with a screw 4, and the screw 4 is used for fixing the body of the target vehicle.

The upper frame 1 to be installed with the automobile body is assembled with the installation base 2 through the lock catch component 3, and the quick disassembly and assembly of the upper frame 1 and the installation base 2 can be realized.

As shown in fig. 1, 2 and 3, the locking assembly 3 includes a first support 31, a latch 32, a second support 33, a guide groove 34, a hook 35 and a buckle 36. The first supports 31 are disposed at two opposite sides of the upper frame 1, and the first supports 31 are specifically mounted at two ends of the second cross bar 11.

The lower end of the first support 31 is connected with the bolt 32. As shown in fig. 2, the latch 32 has a tapered structure with a large top and a small bottom, and the long side of the taper is connected to the first holder 31. The taper provides the pin 32 with a third slope 323 and a fourth slope 324. As shown in fig. 1, the second supports 33 are disposed at opposite sides of the mounting base 2, and the second supports 33 correspond to the first supports 31 in position. The second support 33 is specifically mounted at the end of the first side rail 22. A guide groove 34 is formed in the second support 33, and the guide groove 34 is a tapered groove adapted to the plug pin 32. When the upper frame 1 is mounted on the mounting base 2, the latch 32 is inserted into the guide groove 34.

The side that the bolt 32 that is close to each other of relative two that sets up is equipped with the first inclined plane 321 of downward sloping, two that set up relatively be equipped with the second inclined plane 322 of downward sloping on the side that the bolt 32 was kept away from each other, first inclined plane 321 is close to the lower tip setting of bolt 32, second inclined plane 322 sets up from the top down wholly, makes the bottom face of bolt 32 meets and is less than the top. By partially disposed, it is meant that the upper end is planar and the lower end is beveled, with the channel 34 being planar on that side. By integrally disposed, it is meant that all are beveled, with the channel 34 being beveled on that side. Meanwhile, the guide groove 34 is provided therein with slopes adapted to the third slope 323 and the fourth slope 324.

That is, the second inclined surface 322 is adapted to the inclined surface of the guide groove 34, and the plane of the upper end of the first inclined surface 321 is attached to the plane of the guide groove 34, so that a gap is formed between the first inclined surface 321 and the guide groove 34, and machining errors can be overcome. The bolt 32 and the guide groove 34 adopt a combined fixing mode of plane, inclined plane adaptation and fitting, so that the bolt 32 can be quickly inserted into the guide groove 34 of the second support 33 on one hand, and effective positioning is realized on the other hand.

As shown in fig. 2, the hook 35 is provided on the outer end surface of the first seat 31, as shown in fig. 3, the snap 36 is provided on the outer end surface of the second seat 33, and the snap 36 is fitted with the hook 35 (as shown in fig. 1).
