Abstract
The invention discloses a kind of safety-type chain stay of electric bicycle, one safeties are set between chain stay and vehicle frame, the safeties include the frame connecting plate being fixedly connected with vehicle frame, the chain stay connecting plate being fixedly connected with chain stay, connecting hole is respectively arranged with frame connecting plate and the chain stay connecting plate, and one of connecting hole is arcuate socket, another connecting hole is circular hole；The shank portion of one fastener links together frame connecting plate and chain stay connecting plate through two connecting holes, and by the shank portion of fastener, arcuately hole motion can do relative motion between frame connecting plate and chain stay connecting plate.In normally travel, the present invention does not influence incabloc function, if the junction of chain stay and vehicle frame is broken, this safeties plays safety effect at once.Now electric bicycle can slowly ride and swimmingly carry out, and without the unexpected fracture due to vehicle frame chain stay ear, electrical salf-walking back wheels of vehicle separates with vehicle frame so that personnel's tumble injury of riding.
Description
Technical field
The present invention relates to electric bicycle field, relates in particular to a kind of safety-type chain stay of electric bicycle.
Background technology
Electric bicycle in use, due to jolting for road surface, so electric car is designed as shock-absorbing, for shock-absorbing
The vehicle frame of type is completed by rotary shaft and shock absorber, as shown in figure 1, still such electric bicycle, chain stay 200 with
The junction 300 of vehicle frame 100 is due to stress concentration, it may occur that and fracture, fracture of frame occurs in motion for the personnel that ride can be injured,
It can be in peril of one's life when serious.
The content of the invention
In view of the above-mentioned problems, it is an object of the invention to provide a kind of safety-type chain stay of electric bicycle, it is existing to solve
The problem of fracture of the junction of chain stay and vehicle frame produces potential safety hazard in technology.
To achieve these goals, technical scheme is as follows：
The safety-type chain stay of electric bicycle a, it is characterised in that safeties, the guarantor are set between chain stay and vehicle frame
Dangerous device includes the frame connecting plate being fixedly connected with vehicle frame, the chain stay connecting plate being fixedly connected with chain stay, the vehicle frame connection
The connecting hole to securing member is respectively arranged with plate and chain stay connecting plate, and one of connecting hole is arcuate socket, separately
One connecting hole is circular hole；The shank portion of one fastener passes through two connecting holes by frame connecting plate and chain stay connecting plate
Link together, and by the shank portion of fastener, arcuately hole motion can do phase between frame connecting plate and chain stay connecting plate
To motion.
In a preferred embodiment of the invention, frame connecting plate and Frame Welding.
In a preferred embodiment of the invention, chain stay connecting plate welds with chain stay.
In a preferred embodiment of the invention, the connecting hole on the frame connecting plate is arcuate socket.
In a preferred embodiment of the invention, the shank portion of the fastener is staircase structural model, including one section
The enlarged diameter section that reduced diameter section and one end coordinate with circular hole, the reduced diameter section is corresponding with arcuate socket, is arranged outside reduced diameter section
There is a shank portion bearing that arcuately hole is moved in order to fastener.Further, set between the bearing and arcuate socket
There is wear-resisting steel bushing.Further, fixed briquetting and packing ring are provided with the outside of arcuate socket, a clamp nut is connected to the outer of packing ring
Side.
In normally travel, due to that can be done relative motion between frame connecting plate and chain stay connecting plate, the present invention does not influence
Incabloc function, if the junction of chain stay and vehicle frame is broken, this safeties plays safety effect at once.Now, vehicle frame
Connecting plate and chain stay connecting plate are also connected together, but have loosening, and electric bicycle can slowly ride and swimmingly carry out, without
It can be separated due to the unexpected fracture of vehicle frame chain stay ear, electrical salf-walking back wheels of vehicle with vehicle frame so that personnel's tumble injury of riding.
The present invention can have the function that security insurance.
The present invention has the characteristics of simple in construction, easy for installation.
The features of the present invention see this case schema and the following preferably detailed description of embodiment and obtain clearly
Solution.

Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Close specific embodiment and the present invention is expanded on further.
Referring to Fig. 2 and 3, a kind of safety-type chain stay of electric bicycle, a safeties are set between chain stay and vehicle frame.Protect
Dangerous device includes being fixedly connected with vehicle frame（Welding）Frame connecting plate 1, be fixedly connected with chain stay（Welding）Chain stay connecting plate
2, the connecting hole to securing member is respectively arranged with frame connecting plate and chain stay connecting plate, wherein, referring to Fig. 4-6, car
The connecting hole of frame connecting plate is arcuate socket 11, and the connecting hole of chain stay connecting plate is circular hole 21（It can also be the company of chain stay connecting plate
It is arcuate socket to connect hole, and the connecting hole of frame connecting plate is circular hole）.
Referring to Fig. 3 and 7, the shank portion of a fastener 3 connects frame connecting plate and chain stay through two connecting holes
Fishplate bar links together.The shank portion of fastener is staircase structural model, including one section of reduced diameter section 31 and one end are matched somebody with somebody with circular hole
The enlarged diameter section 32 of conjunction.Reduced diameter section is corresponding with arcuate socket, and a rod body part in order to fastener is arranged with outside reduced diameter section
Divide the bearing 4 of arcuately hole motion.Wear-resisting steel bushing 5 is provided between bearing and arcuate socket.It is provided with the outside of arcuate socket solid
Level pressure block 6 and packing ring 7, a clamp nut 8 are connected to the outside of packing ring.
By the shank portion of fastener, arcuately hole motion can do relative fortune between frame connecting plate and chain stay connecting plate
It is dynamic.In normally travel, due to that can be done relative motion between frame connecting plate and chain stay connecting plate, the present invention does not influence shock-absorbing work(
Can, if the junction of chain stay and vehicle frame is broken, this safeties plays safety effect at once.Now, frame connecting plate
Also it is connected together with chain stay connecting plate, but has loosening, electric bicycle can slowly rides and swimmingly carry out, and simply left and right has
The sensation rocked, personnel's vehicle trouble of riding is reminded, is please repaired in time, ensure the life security for the personnel that ride.
General principle, principal character and the advantages of the present invention of the present invention has been shown and described above.The technology of the industry
