Description

Novel frame structure of bicycle

Technical Field

The utility model relates to a bicycle technical field especially relates to a novel frame structure of bicycle.

Background

Electric bicycles are generally more suitable for use in long distance travel and have the advantage of a large load capacity, and therefore have higher requirements for shock absorption and comfort. The design to the whole frame of bicycle then need carry out continuous optimization and improve and reach best shock attenuation and comfortable effect, the swing arm that current conventional frame bumper shock absorber is connected, the connection piece that all sets up behind the seat pipe usually cup joints with the connection piece that the back fork is connected and forms, so strong enough to the stability of automobile body, can lead to the connection piece to warp under the too big condition of atress, for this reason we have made the improvement to this structure, have better shock attenuation effect when increasing frame stability.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel frame structure of bicycle to solve the problem that proposes among the above-mentioned background art.

In order to realize the above object, the utility model provides a following technical scheme, a novel frame structure of bicycle, sit the pipe including the frame, sit tub front portion connection automobile body girder, rear portion connection automobile body seat frame, the welding of lower part rear has a battery to hold and puts the bottom plate, the bottom plate rear end extends there is the curb plate, the curb plate embolias automobile body seat frame forms the battery jar, automobile body seat frame passes through the bumper shock absorber and connects the back vent, a serial communication port, the back vent pass through the swing arm with sit the external member swing joint of tub lower part front side, the swing arm cover is established battery jar lower part both sides.

Preferably, the sleeve is provided with a sleeve hole, and the swing arm is rotatably connected to the sleeve hole through a screw.

Preferably, the shock absorber comprises a shock absorbing spring, and two ends of the shock absorber are respectively and rotatably connected with the vehicle body seat frame and the rear fork.

Preferably, the side plate abuts against a cross bar of the vehicle body seat frame.

Preferably, a central shaft tube is arranged above the sleeve piece and connected with the main beam of the vehicle body through a rod piece.

Compared with the prior art, the beneficial effects of the utility model are that: this embodiment novel frame structure of bicycle, the external member direct with sit pipe integrated into one piece setting and sit pipe lower extreme front side, make the intensity stability of external member is higher, the swing arm passes through the screw rod and rotates with the external member and cup joint, because the external member directly sets up sit the pipe front side, thereby increased the length of swing arm reaches better shock attenuation effect, simultaneously the arm board of swing arm is the whole board, and the cover presss from both sides in the both sides of battery jar, and the effectual battery occupation space of having avoided to the influence of effect of moving away to avoid possible earthquakes, still better protection the battery, and avoided two conventional connecting plates to connect the wearing and tearing of the protruding nut to the battery case in the swing arm that forms.

Detailed Description

The technical solutions in the embodiments of the present invention are described below clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 and 2, in order to achieve the above object, the present invention provides a novel frame structure of a bicycle, including a frame seat tube 1, the front portion of the seat tube 1 is connected to a main beam 2 of the bicycle body, the rear portion of the seat tube is connected to a seat frame 3 of the bicycle body, a bottom plate 4 for supporting and placing a battery is welded at the rear of the lower portion of the seat tube, a side plate 41 is extended at the rear end of the bottom plate 4, the side plate 41 is sleeved in the seat frame 3 of the bicycle body to form a battery jar 10, the seat frame 3 of the bicycle body is connected to a rear fork 6 through a shock absorber 5, the rear fork 6 is movably connected to a sleeve member 8 at the front side of the lower portion of the seat tube 1 through. This embodiment is a novel frame structure of bicycle, the external member 8 direct with sit 1 integrated into one piece setting of pipe and be sitting a tub lower extreme front side, make the intensity stability of external member 8 is higher, swing arm 7 rotates through screw rod 81 and external member 8 and cup joints, because external member 8 directly sets up sit 1 front side of pipe, thereby has increased the length of swing arm 7 reaches better shock attenuation effect, simultaneously the arm board of swing arm 7 is the whole board, and the cover presss from both sides battery jar 10's both sides, and the effectual battery occupation space that has avoided the influence to the effect of moving away to avoid possible earthquakes, and avoided two conventional connecting plates to connect the wearing and tearing of nut arch to the battery case on the swing arm of formation.

Preferably, the sleeve 8 is provided with a sleeve hole, and the swing arm 7 is rotatably connected to the sleeve hole through a screw rod 71, so that a corresponding damping effect is achieved.

Preferably, the shock absorber 5 comprises a shock absorbing spring, and two ends of the shock absorber 5 are respectively connected with the vehicle body seat frame 3 and the rear fork 6 in a rotating mode, so that the stability and the comfort of the vehicle body are improved.

Preferably, the side plate 41 abuts against a cross bar 31 of the vehicle body seat frame, so that the stability of the battery jar is improved, and the battery is prevented from easily shaking.

Preferably, a central axis pipe 9 is arranged above the sleeve member 8, and the central axis pipe 9 is connected with the main beam 2 of the vehicle body through a rod member 91, so that the whole vehicle frame is firmer.
