Description
Technical field
The utility model relates to a kind of battery-driven car wheel rim, relates in particular to a kind of board-like wheel rim of battery-driven car that has board-like wheel rim.
Technical background
The car wheel structure of battery-driven car generally comprises wheel rim, wheel hub and spoke, sometimes for the integrally-built compactedness of battery-driven car, need be arranged on motor the position of wheel, thereby the car wheel structure of existing structure not too is adapted to the installation of motor.The car wheel structure of existing structure generally only is the wheel rim of a round, is welded with a board-like wheel rim on the inside face of wheel rim, and motor is set at the wheel rim inboard.The outer peripheral face of electric vehicle wheels arrangement is provided with tire, the branch that tire has vacuum structure and has inner tube of a tyre structure, and present most electric vehicle tyre all adopts the vacuum tyre structure.The tire of this vacuum tyre structure need be provided with a penetrating valve port on wheel rim, be provided with the valve seat in pore, and the outer end of valve seat is connected with valve, so that be the electric vehicle tyre inflation.The inner end of valve seat has plush copper, and the valve seat passes valve port, and the inner end surface of valve seat plush copper and the inside face of wheel rim fit together, to realize the vapor seal between valve seat and the wheel rim.And actual conditions are, usually all be arcwall face in the position of valve port on the wheel rim inside face, and the valve seat itself has the certain rigidity requirement, the inner end surface of valve seat plush copper is difficult to make and this arcwall face adaptive shape that matches, when if swing takes place in the valve seat under the effect that is subjected to external force, can have influence on the air-tightness between valve seat and the wheel rim inside face, tire meeting so and the phenomenon that leaks air.
Summary of the invention
For overcoming above-mentioned defective, the new technical issues that need to address of this practicality are: provide a kind of battery-driven car board-like wheel rim, after the valve seat is connected on this wheel rim, the connective stability of valve seat on wheel rim is good, air-tightness between valve seat and the wheel rim is guaranteed, and tire is difficult for the phenomenon of generation from leaking gas between valve seat and the wheel rim.
In order to solve the technical problem, the technical solution of the utility model: the board-like wheel rim of a kind of battery-driven car, comprise wheel rim body and the board-like wheel rim that is fixedly connected on wheel rim body inner peripheral surface, the wheel rim body is provided with penetrating valve port, is provided with the valve seat in the valve port, is connected with valve on the valve seat, it is characterized in that, the outside end face of described wheel rim body is provided with connecting element, has interface arrangment on the valve seat, and connecting element is connected on the interface arrangment.Have plush copper on the valve seat, after the valve seat was assemblied in the valve port, the inside face of the inner end surface of plush copper and wheel rim body fitted together.Setting by relative position between interface arrangment and the connecting element, after both are connected together mutually, can make between the inside face of the inner end surface of plush copper and wheel rim body to have certain compressing in advance, to guarantee the close property between plush copper inner end surface and the wheel rim body internal surface.
As preferably, described connecting element is round, and described interface arrangment is a circular groove of being located at valve seat corresponding position, and connecting element is connected in the circular groove.The connecting element hoop of round is connected on the position of valve seat circular groove, can realize compressing between valve seat plush copper inner end surface and the wheel rim body internal surface on the one hand, can make the radial stability of valve seat on the wheel rim body on the other hand, even external force acts on the valve, can not cause the swing of valve seat plush copper on the wheel rim body yet, further improve the air-tightness between valve seat plush copper the inner and the wheel rim body internal surface.
As preferably, have opening on the described round connecting element, the size of this opening is less than the external diameter of valve seat in the circular groove position.This opening the assembling that has made things convenient between valve seat and the wheel rim body is set, and the dimensional characteristic of opening makes the setting of opening can significantly not reduce the fixation of connecting element to the valve seat.
As preferably, described opening is towards the radial outside of wheel rim body.Opening is adapting to the status requirement of valve on the wheel rim body on the connecting element with occupying a good place, has guaranteed the property easy to assembly of valve seat.
As preferably, described wheel rim body outside end face is provided with annular groove, and described connecting element is fixedly connected in the groove.Connecting element is positioned at this groove, has made things convenient for the captive joint of connecting element, and the compact overall structure of wheel rim is good.
Therefore, the beneficial effects of the utility model:
Owing to be provided with connecting element at the outside of wheel rim body end face, and the corresponding position on the valve seat is provided with interface arrangment, connecting element is connected together mutually with interface arrangment, by the relative position setting between the interface arrangment on connecting element and the valve seat, can effectively guarantee between the inner end surface of valve seat plush copper and the wheel rim body internal surface to have improved the air-tightness between valve seat and the wheel rim body for closely cooperating.And the setting of connecting element, after making that also external force acts on the valve, the valve seat has preferably stability, the plush copper on the valve seat be difficult for the wheel rim body between the relative swing of generation, the air-tightness between plush copper inner end surface and the wheel rim body internal surface is well guaranteed.
Description of drawings
Accompanying drawing 1 is the local structure scheme drawing of a direction of the board-like wheel rim of the utility model battery-driven car.
Accompanying drawing 2 is local structure scheme drawings of another direction of the board-like wheel rim of the utility model battery-driven car.
The specific embodiment
As can be seen from Figure, the structure of the board-like wheel rim of the utility model battery-driven car comprises wheel rim body 1 and the board-like wheel rim 2 that is fixedly connected on wheel rim body 1 inner peripheral surface.Wheel rim body 1 is provided with penetrating valve port 3, runs through being provided with valve seat 5 in this valve port 3, and the inner end of valve seat 5 has plush copper, and the outer end is connected with valve 7.The size of plush copper is greater than the internal diameter of valve port 3, plush copper is connected on the inside face of wheel rim body 1, fit together between the inside face of the inner end surface of plush copper and wheel rim body 1, with the vapor seal between realization plush copper and the wheel rim body 1, thereby make enclosed cavity that is used to hold air of formation between tire and the wheel rim body 1.
On the end face of the outside of wheel rim body 1, be provided with connecting element 4, on valve seat 5, be provided with and be used for and connecting element 4 interface arrangment of clamping mutually.This interface arrangment is a circular groove 6 of being located at indent on the valve seat 5, and connecting element 4 is a round, and the connecting element 4 of round is connected in the circular groove 6, and makes the inner end surface of plush copper be pressed on the inside face of wheel rim body 1.
