Specific implementation mode

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally The every other embodiment that field those of ordinary skill is obtained without making creative work, belongs to this practicality Novel protected range.

- Fig. 4 is please referred to Fig.2, Fig. 2 is a kind of structural representation of specific implementation mode of vehicle frame provided by the utility model Figure；Fig. 3 is the local broken away view of vehicle frame described in Fig. 2；Fig. 4 is the structural schematic diagram of supporting rack in vehicle frame shown in Fig. 2.

In a specific embodiment, vehicle frame provided by the utility model is used for bicycle or electric booster bicycle, this Embodiment is by taking shared bicycle as an example.In shared bicycle, vehicle frame provided by the utility model includes for installing rear wheel Back vent 1, the standpipe 2 for installing the back vent 1, the front tube 3 for installing handle group, and be connected to the front tube 3 with it is described Down tube 4 between standpipe 2；Further include the supporting rack 5 being installed between the back vent 1 and the front tube 3, support frame as described above 5 wraps It includes the first tube body 51 and there is the second tube body 52 of default lateral distance, first tube body 51 and institute with first tube body 51 It states and forms object accommodating space 53 between the second tube body 52, the object accommodating space is for accommodating special article.Wherein back vent 1 wraps The first seat stay 11 and the second seat stay 12 are included, the first seat stay 11 and 51 homonymy of the first tube body are arranged, the second seat stay 12 and the second tube body 52 homonymies are arranged, and the transverse direction between above-mentioned two tube body refers to the left and right directions of car body.

Above-mentioned object accommodating space can be formed by first tube body 51 and second tube body 52, and article can press from both sides at this time It holds and is fixed between two tube bodies；Object accommodating space can also be by first tube body, second tube body and the vehicle frame Down tube three between formed, at this point, after article is gripped by two tube bodies, down tube can also be utilized to realize support, improved Object places effect.

Further, one end of first tube body 51 is fixed in the front tube 3, and the other end is fixed in the back vent 1 The first seat stay 11；One end of second tube body 52 is fixed in the front tube 3, and the other end is fixed in the of the back vent 1 Two seat stays 12.That is the length of two tube bodies extends to the seat stay position of homonymy from front tube 3, and passes through the connection with front tube 3 and seat stay It realizes and fixes, structure is relatively reliable, avoids occurring stress concentration at back vent 1, structural stability is more preferable.It is apparent that two standpipes 2 One end far from front tube 3 can be mounted at the homonymy chain stay of back vent 1, or be each attached at standpipe 2.

51 and second tube body 52 of above-mentioned first tube body all can be the forms such as metal circular tube or metal side tube, both ends difference It is fixedly connected by welding with the seat stay of front tube 3 and corresponding side.It is apparent that the connection between tube body and front tube 3, seat stay Mode is not limited to weld, or screw connects or the modes such as clamping.

In order to improve the reliability and stability of article placement, band and fixing buckle can also be set on supporting rack 5 Equal binding fixing structures, after placing article, the band bypasses be positioned over the article of the object accommodating space after with institute It is affixed to state fixing buckle, to avoid ride jolt when, fall off on article self-supporting frame 5, to ensure article installation reliability.

In this way, since two tube bodies are placed side by side and form object accommodating space 53, specific article (such as water bottle, kettle Deng) can be positioned in object accommodating space 53, and gripped by two tube body realizations, ensure the stabilization that article is placed Property；The storage that the vehicle frame realizes special article by the improvement of structure extends vehicle frame to improve the integration of vehicle frame Use function, and then improve experience of riding.

In order to improve the structural stability and connection reliability of supporting rack 5, support frame as described above 5 by fixed arm 6 with it is described Down tube 4 is fixedly connected.Specifically, fixed arm 6 includes connecting rod 61 and fixed link 62, and one end of the connecting rod 61 is fixed in described the One tube body 51, the other end are fixed in second tube body 52, and one end of the fixed link 62 is fixed in the connecting rod 61, another One end is fixed in the down tube 4.Between above-mentioned connecting rod 61 and fixed link 62, between the first tube body 51 and connecting rod 61, the second tube body It is welding structure between 52 and connecting rod 61 and between fixed link 62 and down tube 4, to ensure that connection is reliable, and reduces technique Cost.

In addition to above-mentioned vehicle frame, the utility model also provides a kind of vehicle including above-mentioned vehicle frame, other each portions of the vehicle Refer to the prior art for separation structure, and this will not be repeated here.Specifically, the vehicle be specially bicycle, electric vehicle or electric power-assisted from Driving, wherein bicycle can be private savings bicycle or shared bicycle.

Although the embodiments of the present invention have been shown and described above, it is to be understood that above-described embodiment is Illustratively, it should not be understood as limiting the present invention, those skilled in the art are in the scope of the utility model Inside it can make changes, modifications, alterations, and variations to the above described embodiments.
