Embodiment 1

[0048] see figure 1 — Figure 10 , a connecting device suitable for flipping the bracket assembly, including an upper connecting piece 4, the upper connecting piece 4 includes a connecting middle plate 41 and connecting wing plates 42 connected to its two ends, and the ends of the connecting middle plate 41 It is connected with the bottom end of the connecting wing plate 42, and the top end of the connecting wing plate 42 extends upwards. The top end of the connecting wing plate 42 is provided with a wing connecting hole 431 connected with the cab 8. The hole surface 433 of the wing connecting hole 431 is On the horizontal plane, the hole surface 433 intersects the plate surface 412 connecting the middle plate 41 . The top of the connecting wing plate 42 is connected to the side of the flat connecting platform 43, and the middle part of the flat connecting platform 43 is provided with a through wing connecting hole 431. The top surface of the flat connecting platform 43 is a ...

Embodiment 2

[0050] Basic content is the same as embodiment 1, the difference is:

[0051] The connecting wing 42 is a No. 1 sub-wing 45 and a No. 2 sub-wing 46. The bottom of the No. 1 sub-wing 45 is connected to the left end of the connecting middle plate 41, and the bottom of the No. 2 sub-wing 46 is End is connected with the right end of connecting middle plate 41, and the length of No. 2 sub-wing board 46 is greater than the length of No. 1 sub-wing board 45. The connection structure between the No. 1 sub-wing 45 and the connecting middle plate 41, and the connection structure between the No. 2 sub-wing 46 and the connecting middle plate 41 are obliquely handed over. The included angle 451 of the No. 1 wing between the No. 1 sub-wing 45 and the connecting middle plate 41 is an obtuse angle, and the No. 2 wing between the No. 2 sub-wing 46 and the connecting mid-plate 41 is obtuse. The included angle 461 is an obtuse angle, and the included angle 461 in the second wing is larger than ...

Embodiment 3

[0053] Basic content is the same as embodiment 1, the difference is:

[0054] The connection device also includes a lower turning member 3, which includes an outer connecting portion 5 and an inner connecting portion 6, and the middle part of the outer connecting portion 5 is provided with a shaft passing hole 51 for the turning shaft 1 to pass through. , the right side part of the external connection part 5 is connected with the left side part of the internal connection part 6, the top surface of the internal connection part 6 is connected with the cab 8, and the top of the external connection part 5 is provided with a concave snap-in mechanism 7 The clamping mechanism 7 includes a No. 1 inclined plane 710 and a No. 2 inclined plane 720. The distance between the top of the No. 1 inclined plane 710 and the No. 2 inclined plane 720 is greater than the distance between the bottoms. , the angle 44 formed between the connecting wing plate 42 and the first inclined plane 710 is an ...

Abstract

The utility model discloses a connecting device suitable for a turnover support assembly. The connecting device comprises an upper connecting piece; the upper connecting piece comprises a connecting middle plate and connecting wing plates connected with the two ends of the connecting middle plate; the end part of the connecting middle plate is connected with the bottom ends of the connecting wingplates; the top ends of the connecting wing plates extend upwards; wing connecting holes connected with a cab are formed in the top ends of the connecting wing plates; the hole surfaces of the wing connecting holes are horizontal planes; and the hole surfaces are intersected with the plate surface of the connecting middle plate. Besides, a lower overturning piece can be additionally arranged; thelower overturning piece comprises an outer connecting part and an inner connecting part; the top of the outer connecting part is vertically connected with the upper connecting piece in a clamped mode;a shaft passing hole allowing an overturning shaft to penetrate through is formed in the middle of the outer connecting part; the right side of the outer connecting part is connected with the left side of the inner connecting part; and the top face of the inner connecting part is connected with the cab. According to the design, the tightening difficulty of connecting bolts is low, the assemblingefficiency is high, the connecting firmness is high, and light weight can be achieved easily.

Description

technical field [0001] The invention relates to a design of an overturning bracket connected with a driver's cab, belongs to the technical field of an overturning bracket assembly of a light commercial vehicle, and in particular relates to a connecting device suitable for the overturning bracket assembly. Background technique [0002] In the current technology, the connection method between the flip bracket assembly and the cab is generally to set two fixed points on the front beam, and to set three fixed points on the left and right longitudinal beams respectively. However, due to changes in the driving structure, the There is no fixed point, all fixed points can only be arranged on the left and right longitudinal beams, which squeezes the assembly space, and because the connecting bolts can only be tightened from bottom to top, but due to the blocking of the front suspension bracket assembly, the bracket is flipped The multiple connecting bolts on the assembly cannot be ti...
