Description

The combination vehicle rack device of electric cycle

Technical field

The utility model relates to a kind of bicycle frame device, relates in particular to a kind of combination vehicle rack device of electric cycle.

Background technology

Be illustrated in figure 1 as the TaiWan, China patent announcement No. 87217435, name is called " vehicle frame hooks together isolating construction before and after the car of riding instead of walk ", it has disclosed a kind of composite construction of the vehicle carriage of riding instead of walk, this car 1 of riding instead of walk has a front vehicle frame 11 and a back vehicle frame 12, front vehicle frame 11 has two respectively from front vehicle frame 11 hook plate 111 and chimeric block 112 of extending of vehicle frame 12 directions backward, offer an embedded hole 113 on this chimeric block 112, back vehicle frame 12 has two hooking blockings 121 that extend toward front vehicle frame 11 directions from back vehicle frame 12 respectively, one base 122, and a pull handle 123 that is arranged on this base 122.

When assembling, back vehicle frame 12 stands on the ground, and front vehicle frame 11 is positioned at the relative top of back vehicle frame 12 and is perpendicular to one another, the user must help front vehicle frame 11 on the other hand, another is hand steered holds back vehicle frame 12, so that the hook plate 111 of front vehicle frame 11 and the hooking blocking 121 of back vehicle frame 12 are hooked together together, and back vehicle frame 12 is passed toward horizontal directions, pulling pull handle 123 down moves outward and is extended through in the embedded hole 113, and the car 1 of riding instead of walk is finished in assembling by this.

Yet, car 1 is to locate by the hook plate 111 of front vehicle frame 11 and the hooking blocking 121 mutual engagings of back vehicle frame 12 owing to ride instead of walk, so in assembling process, often because front vehicle frame 11 must be a vacant state with the manpower support, therefore, if can't provide enough supports just can cause front vehicle frame 11 to drop or downward-sloping, make that the hook plate 111 of front vehicle frame 11 is separated from one another with the hooking blocking 121 of back vehicle frame 12, thereby usually need two physiognomy interworkings to close to reach smooth stack-mounted purpose, but the car of riding instead of walk basically stress nothing more than be carry light and handy and easy to assembly, though can by disassemble become before, back

vehicle frame

11,12 take volume with minimizing, if can finish assembling but still need many people to cooperate, then in practical operation, will lack convenience.

The utility model content

Therefore, the purpose of this utility model provides a kind ofly singlely just can finish the stack-mounted bicycle frame device of car of riding instead of walk, and can reduce the stack-mounted complexity.

For this reason, the utility model provides a kind of combination vehicle rack device of electric cycle, include: one first vehicle frame, has a center link, and two edges laterally lay respectively at this center link two opposite sides and side bar parallel to each other, and described center link comprises two respectively from the stop block of the horizontal two opposite sides of this center link projection outward; Second vehicle frame that one and first vehicle frame is in the same plane has an axostylus axostyle, and the center link of first vehicle frame is perpendicular to the axostylus axostyle of second vehicle frame; An and clip unit, have one first blocking part, two second blocking parts, two and lay respectively at axostylus axostyle on the contrary away from projection and two position-limited troughs that are formed at respectively on each side bar at two ends, described first blocking part is from the outside projection in the center link top of first vehicle frame, and be located along the same line with center link, be used for the axostylus axostyle of grab at described second vehicle frame, described second blocking part compartment of terrain respectively is positioned on the axostylus axostyle of second vehicle frame, and match with each stop block respectively, described position-limited trough opening and matches with corresponding projection down.

The combination vehicle rack device of electric cycle of the present utility model also comprises locating unit, this positioning unit has one and is fixedly arranged on permanent seat, on first vehicle frame and is fixedly arranged on base, on second vehicle frame and is positioned at operational group and positioning piece between permanent seat and base, described permanent seat has the outside chute of an opening, described operational group has a pipe link and a pushing tow handle, described pushing tow handle is arranged at the end of pipe link away from base, and described locations is articulated in the other end of pipe link on the base; Described pipe link is extended through in the chute of described permanent seat pivotly, and described pushing tow handle is resisted against on the described permanent seat.

By first blocking part and axostylus axostyle and second blocking part and stop block cooperatively interact and relative motion is finished and is engaged, and each projection can spinning in each position-limited trough, thereby make the user can singlely finish assembly working, and do not need by extra accessory appliances, therefore not only reduced the assembling complexity, more can assemble at short notice and finish, and under the cooperation of positioning unit, can guarantee first, the steadiness that makes up between two vehicle frames, stable to guarantee integral structure, and then increase driving safety, when pursuing simple and convenient assembly, practicality and safety have also been taken into account simultaneously.
