Description
Technical field
This utility model relates to a kind of cycle frame, particularly to a kind of monoblock type cycle frame exempting from welding.
Background technology
Conventional bicycle frame generally steel pipe or aluminum pipe by different size forms.As shown in FIG. 1A and 1B, tradition is certainly
Driving vehicle frame 1 can include front pipe 11, a pair prior art back vent 12, be arranged at front pipe 11 front end for installing handlebar and front fork
Head tube 13 and the seat pipe 14 of two intersection points of pipe 11 and prior art back vent 12 before connecting, wherein before pipe by upper pipe 111 He
Down tube 112 is constituted, and each prior art back vent 12 respectively further comprises fork 121 and lower fork 122.These pipe fittings need by weldering
Connect the whole vehicle frame of composition that joins end to end each other, group particularly important during causing welding sequence to become cycle frame production
Become part.Owing to welding procedure itself exists generation chemical fumes, pollutes environment, automatization's cost is high, easily occur that joint is hidden
The defects such as trouble, therefore exempt to weld cycle frame or the few cycle frame of welding demand will be becoming increasingly popular.
In order to reduce the demand of welding, the utility model of Patent No. ZL03284253.8 discloses a kind of steel plate punching press type
Cycle frame, it is overall cycle frame that punching press of steel plate is made front cant beam with rear support stand by it, efficiently solves
The problem of welding, but its front cant beam and rear support stand are tabular, and not only profile is rough unsightly, anti-side knock ability is also
The round tube shape that is far from is strong.The utility model of Patent No. ZL201120365355.2 discloses a kind of overall punching press vehicle frame, its
It is bonded complete vehicle frame, although remain the tubular structure of tradition vehicle frame after vehicle frame is divided the two pieces of punching presses in left and right, but on a left side
Right two agllutinations still need to be realized by welding when closing, and can not effectively exempt or reduce the impact that welding brings.
Utility model content
In order to overcome the defect in the presence of prior art, this utility model provides based on punching press or the entirety of extrusion process
Formula cycle frame, it not only completely avoid the welding sequence in production process, it is ensured that the anti-horizontal stroke that tubular structure is good
To impact capacity.
A kind of monoblock type cycle frame of the present utility model, including:
Front-axle beam, front-axle beam comprises upper beam and underbeam；

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with embodiment, to this
Utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain that this practicality is new
Type, is not used to limit this utility model.
Fig. 2 is the schematic diagram according to monoblock type cycle frame of the present utility model (hereinafter referred to as vehicle frame) 2.Such as Fig. 2 institute
Showing, vehicle frame 2 generally includes front-axle beam 21, back vent 22, head tube 23 and seat pipe 24, and above-mentioned part is by punching press or extrusion process one
Molding.Wherein front-axle beam 21 includes upper beam 211 and underbeam 212, and back vent 22 includes Seat stay 221 and Chain stay 222.Head tube 23 is arranged
In one end of front-axle beam 21, as it can be seen, one end of upper beam 211 and underbeam 212 crosses at head tube 23.Seat pipe 24 is positioned at front-axle beam 21
And between back vent 22, wherein underbeam 212 and Chain stay 222 are intersected in one end of seat pipe 24, and upper beam 211 crosses with Seat stay 221
In the other end close to seat pipe 24.
Compared with prior art, vehicle frame 2 of the present utility model uses single-arm rear fork, and the most only side at rear wheel is (left
Side or right side) back vent 22 is set, the overall weight of vehicle frame 2 be can not only correspondingly alleviate, punching press or extrusion process are also convenient for
Operation.In order to ensure front wheel with trailing wheel point-blank, back vent 22 (does not shows to wheel away from one end of front-axle beam 21
Go out) side deflection, be i.e. perpendicular to the plane at front-axle beam 21 place to side deflection.In an embodiment of the present utility model,
Back vent 22 is away from one end deflection about 60mm-100mm on the right side of wheel of front-axle beam 21.Alternatively, it also can be on the left of wheel
Deflection appropriately distance, to guarantee that front wheel is with trailing wheel point-blank.
In this utility model, the shape of cross section of each several part of vehicle frame 2 is C-shaped so that it is have good anti-side face punching
The ability hit.Preferably, the opening direction in C-shaped cross section can be contrary with the skew direction of back vent 22.Such as, when back vent 22 is to car
On the right side of wheel during deflection, the shape of cross section of vehicle frame 2 each several part can be opening C-shaped to the left.
In order to increase practicality, it is simple to install the adnexaes such as vehicle seat, handlebar, front fork in the corresponding position of vehicle frame 2, can be in phase
The position answered is arranged at the C button that C-shaped cross section matches.As it is shown on figure 3, on seat pipe 24 top, the C-shaped cross section opening part of head tube 23
C button is set so that it is local has tubular structure, just can install the general vehicle seat of standard bicycle, handlebar and front fork at this.
In embodiment of the present utility model, C button can fasten such mechanical fasteners mode by welding or such as bolt and be fixed on seat
On pipe 24 top and head tube 23.
Bulk strength in order to ensure vehicle frame 2, it is possible to use the metallic plate more thick than traditional vehicle frame tube wall is made.Example
As, tradition irony frame tube wall thickness is about 1-2mm, and aluminum frame tube wall thickness is about 2-3mm, disclosed in the utility model
Vehicle frame 2 can use the iron plate of thickness about 3-6mm or the aluminium sheet of thickness about 4-7mm to make.Owing to vehicle frame 2 each several part uses
Be the semi-circular tube structure with C-shaped cross section, and only there is unilateral back vent 22, the most suitably increasing pipe thickness can't make
Vehicle frame 2 overall weight overweights tradition vehicle frame.
Conventional bicycle frame need to realize the welding between each several part from different directions through multiple working procedure, welding difficulty is big,
Automatization's cost is high.By comparison, vehicle frame 2 simple in construction of the present utility model, easily realize full-automation batch production.With
As a example by Sheet Metal Forming Technology, it is only necessary to use traditional press machine that the sheet metal that thickness is suitable is carried out one direction punching press the most available
Integrated vehicle frame 2, not only saves the time of single products that produces, improves productivity ratio, also without using high cost
Automatic assembly line, significantly reduces production cost.
Embodiment described above only have expressed embodiment of the present utility model, and it describes more concrete and detailed, but also
Therefore the restriction to this utility model the scope of the claims can not be interpreted as.It should be pointed out that, for the ordinary skill of this area
For personnel, without departing from the concept of the premise utility, it is also possible to make some deformation and improvement, these broadly fall into this
The protection domain of utility model.Therefore, the protection domain of this utility model patent should be as the criterion with claims.
