Description
Technical field
The utility model relates to electric automobiles, and in particular to a kind of high intensity electric vehicle down tube.
Background technique
The electric vehicle down tube produced on the market now is largely by a hollow circular-tube by compression moulding, will be hollow
During pipe is processed into electric vehicle down tube, hollow pipe increases by one after processing battery mounting base, in inside pipe fitting welding
A reinforcing chip, to increase the intensity of pipe fitting.Above-mentioned electric vehicle down tube structure has the following problems: the above-mentioned electricity manufactured
Motor-car down tube after battery mounting base being processed first with CNC, then in one reinforcing chip of interior welds, will lead in this way
The deformation of hollow pipe causes battery that can not be put into, and battery cover can not be matched with hollow pipe, and weld strength not can guarantee.
In addition, the head tube plumb joint and motor base plumb joint of electric vehicle down tube on the market are to weld up now, this
The intensity of kind electric vehicle down tube is inadequate, it is easy to be broken in welding position, safety is low；There are also another electric vehicle down tube be by
Hollow pipe both ends are milled with CNC into dovetail shaped, then by manual synchronizing dovetail weldering are got up, welding position is ground after being flattened with press machine
Flat to achieve the effect that change welding of the both ends size to cooperate first pipe and motor cabinet, this method can not arbitrarily change headstock
Pipe plumb joint and motor base weld head shapes, and can not bending, straight tube can only be done, limited relatively more.
Utility model content
The purpose of the utility model is to provide a kind of high-intensitive electric vehicle down tubes, to improve battery mounting base in hollow pipe
Intensity and can prevent hollow pipe from deforming.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of high intensity electric vehicle down tube, including hollow pipe are provided with battery mounting base, the battery on the hollow pipe
Mounting base is provided with reinforcing rib, and the reinforcing rib extends to entire battery mounting base length, and described hollow pipe one end reduces bore
Process the head tube plumb joint of bending, the other end reduces the motor base plumb joint that bore processes bending, the hollow pipe with
Head tube plumb joint is integrally formed setting, and the hollow pipe and motor base plumb joint are integrally formed setting.
The setting preferably, reinforcing rib and hollow pipe are integrally formed.Using the above structure, the knot of electric vehicle down tube
Structure is more firm.
Preferably, the reinforcing rib, in flat, the reinforcing rib is located at the lower section inside battery mounting base.Using upper
Structure is stated, flat reinforcing rib is conducive to battery mounting base and installs battery.
Preferably, being provided with several through-holes on the reinforcing rib.Using the above structure, the weight of reinforcing rib is alleviated
Amount.
Preferably, through-hole is spaced substantially equidistant distribution along the length direction of reinforcing rib.Using the above structure, make through-hole point
Cloth is uniform.
Preferably, being provided with reinforcing mat on the reinforcing rib, the grid of the reinforcing mat is arranged in honeycomb structure, institute
It states reinforcing mat and reinforcing rib is integrally formed setting.Using the above structure, the intensity of reinforcing rib is further improved.
The beneficial effects of the utility model are:
1. the high-intensitive electric vehicle down tube of the utility model improves battery by being provided with reinforcing rib in battery mounting base
The intensity of mounting base reduces welding step, prevents hollow pipe from deforming carrying battery and battery cover, make battery and
The parts such as battery cover smoothly assemble；
The setting 2. hollow pipe and head tube plumb joint in the high-intensitive electric vehicle down tube of the utility model are integrally formed,
Hollow pipe and motor base plumb joint are integrally formed setting, and it is big that head tube plumb joint and motor base plumb joint can change bore
It is small, and camber can be made and come out, it is flattened without milling dovetail, without welding, intensity is higher.
