Abstract
The utility model belongs to the technical field of parts of electric tricycles and particularly relates to a front stem reinforcement connector for an electric tricycle. The front stem reinforcement connector comprises a bottom plate (10), and the inner side of the bottom plate (10) is provided with an arc opening (8); a triangular left side plate (9) extending leftwards and a triangular right side plate (7) extending rightwards are arranged on the left and right sides of the bottom plate (10) respectively; a left arc holding piece (5) and a right arc holding piece (6) are used for holding a front stem (11) and arranged at the inner edge of the left side plate (9) and the inner edge of the right side plate (7) respectively, and the bottom plate (10), the left side plate (9), the right side plate (7), the left arc holding piece (5) and the right arc holding piece (6) are made of one steel plate by stamping and bending. Since the left arc holding piece and the right arc holding piece which are formed integrally are arranged on the left side plate and the right side plate, the area of contact between the reinforcement connector and the front stem of the electric tricycle is widened, and structural strength in welding connection is effectively improved.
Description
Technical field
The utility model belongs to electro-tricycle parts technical field, relates in particular to the front standpipe of a kind of electro-tricycle reinforced company fitting.
Background technology
The main camber beam of vehicle frame and the front standpipe of electro-tricycle adopt connection assist to be welded to connect conventionally.Accompanying drawing 1 has shown the concrete structure of conventional connection assist in prior art, can find out, existing connection assist comprises the base plate 4 of inner side with arc port 3, be provided with in the same way bending in the left and right sides of base plate 4, leg-of-mutton left side board 1 and right side board 2, when use, arc port 3 parts of base plate 4 lean against on the outer wall of front standpipe, the interior edge of left side board 1 and right side board 2 is affixed with the outer wall of front standpipe, afterwards front standpipe and this connection assist are welded and fixed, the main camber beam of vehicle frame of electro-tricycle is overlapped on connection assist obliquely, end holds out against the outer wall at front standpipe, afterwards to front standpipe and the main camber beam of vehicle frame, the main camber beam of vehicle frame and connection assist are welded and fixed.In order to strengthen the overall construction intensity of connection assist, base plate 4, left side board 1 and right side board 2 threes adopt the moulding of same steel plate punched to obtain.The connection assist of said structure is because the area contacting with front standpipe less (only having the interior edge of interior edge, left side board 1 and the right side board 2 of arc port 3 to contact) causes weld strength low, in the follow-up assembling process of electro-tricycle or in use procedure, this weld, place easily ruptures, and causes accident.
Utility model content
The utility model provides standpipe reinforced company fitting before a kind of simple in structure, electro-tricycle of effectively promoting standpipe partially connected architecture intensity before electro-tricycle for solving the technical matters existing in known technology.
The technical scheme that the utility model is taked for the technical matters existing in solution known technology is: before a kind of electro-tricycle, standpipe reinforced company fitting comprises the base plate of inner side with arc port, be respectively equipped with in the left and right sides of base plate extend towards homonymy, leg-of-mutton left side board and right side board, be respectively equipped with on the interior edge of left side board and the interior edge of right side board for the left arc of standpipe before encircling and embrace sheet and right arc is embraced sheet, described base plate, left side board, right side board, left arc are embraced sheet and right arc and are embraced sheet each several part and formed by the bending of same steel plate punched.
Advantage of the present utility model and good effect are: the utility model provides the front standpipe of a kind of electro-tricycle simple in structure reinforced company fitting, by arranging on left side board and right side board, integrated left arc is embraced sheet and right arc is embraced sheet, increase the area of contact of attaching parts and front standing tube outer wall, also just directly increased the area of welding, effectively promote the structural strength being welded to connect, avoided the connection assist of existing structure and the problem that front standpipe not prison welding, easy fracture get loose.
Preferably: described left arc is embraced the end that sheet and right arc embrace sheet along being positioned on same circumference with the interior edge of arc port.

Detailed description of the invention
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 2, the utility model comprises the base plate 10 of inner side with arc port 8, be respectively equipped with in the left and right sides of base plate 10 extend towards homonymy, leg-of-mutton left side board 9 and right side board 7, be respectively equipped with on the interior edge of left side board 9 and the interior edge of right side board 7 for the left arc of standpipe before encircling 11 and embrace sheet 5 and right arc is embraced sheet 6.
For promote reinforced company's contact pin overall construction intensity, reduce the difficulty of processing, in the present embodiment, base plate 10, left side board 9, right side board 7, left arc are embraced sheet 5 and right arc and are embraced sheet 6 each several parts and formed by the bending of same steel plate punched.
For promote whole reinforced company fitting and front standpipe 11 outer walls laminating effect, promote welded structure intensity, in the present embodiment, left arc is embraced sheet 5 and right arc and is embraced both ends of sheet 6 along being positioned on same circumference with the interior edge of arc port 8.
Occupation mode: shown in Fig. 3 and Fig. 4, this reinforced company fitting is first affixed with front standpipe 11, the arc port of base plate 10 8 parts are leaned against on the outer wall of front standpipe 11, the interior edge of left side board 9 and right side board 7 is affixed with the outer wall of front standpipe 11, now left arc is embraced sheet 5 and right arc is embraced sheet 6 standpipe 11 from both sides surround respectively, the part contacting with this reinforced company fitting at the outer wall of front standpipe 11 is afterwards welded, and forms solder joint.Afterwards, by main the vehicle frame of electro-tricycle camber beam 12 be overlapped on obliquely on this reinforced company fitting, end holds out against on the outer wall of front standpipe 11, the part that the main camber beam 12 of part, the vehicle frame afterwards main camber beam 12 of front standpipe 11 and vehicle frame being contacted contacts with this reinforced company fitting is welded and fixed, and forms solder joint.
