Abstract
Disclosed is a connection structure of a new energy automobile rear portion anticollision beam. The connection structure comprises a rear wall frame, a window arranged in the rear wall frame, a rear bumper fixed to the lower end of the rear wall frame through a bolt, and an anticollision grating formed by welding steel pipes. Connection supports are installed on the two sides and the upper end of the window in the rear wall frame. Plug bushes are fixed to the connection supports. The ends of the steel pipes of the anticollision grating are inserted into the plug bushes and fastened through sleeve bolts. Anticollision grating forms effective outside network protection for a power battery. The sizes of the plug bushes compensate for size deviation caused by low welding precision of the anticollision grating. Impact force applied to the anticollision grating is transmitted out through the connection supports. The strength is high, assembly is convenient, universality is good, and the cost is reduced effectively.
Description
Technical field
The present invention relates to the attachment structure of a kind of new-energy automobile rear portion collision prevention girders.
Background technology
Along with becoming increasingly popular of new-energy automobile, the security incident relevant to electric automobile the most gradually increases, electrokinetic cell
System Safety Analysis progressively obtains everybody concern with protection.Different products, its type, application, framework have the biggest difference,
The safety approach taked also not exclusively as.Therefore there is poor universality and the high drawback of manufacturing cost.
Summary of the invention
The present invention is to overcome the deficiency of above technology, it is provided that a kind of simple in construction, low cost of manufacture, highly versatile
The attachment structure of new-energy automobile rear portion collision prevention girders.
The present invention overcomes its technical problem be the technical scheme is that
A kind of attachment structure of new-energy automobile rear portion collision prevention girders, including: rear wall frame, the window being arranged in rear wall frame,
The rear bumper being secured by bolts in rear wall frame lower end and the crashproof grid formed by steel-pipe welding, described back wall bone
The both sides of the window in frame and upper end are mounted on connecting support, and sleeve is fixed on connection support, the steel pipe end of crashproof grid
Head is inserted in sleeve and is fastened by sleeve bolt.
The invention has the beneficial effects as follows: crashproof grid defines effective external network chemoprevention and protects electrokinetic cell, passes through
The size of sleeve makes up that the welding precision of crashproof grid is low and the dimensional discrepancy that causes.The impulsive force that crashproof grid receives is passed through
Connecting support to pass, its intensity is high, it is simple to assembling, versatility are good, effectively reduce cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
In figure, 1. the crashproof grid 6. of rear wall frame 2. window 3. rear bumper 4. bolt 5. connects support 7. sleeve.
Detailed description of the invention
1 the present invention will be further described below in conjunction with the accompanying drawings.
The attachment structure of a kind of new-energy automobile rear portion collision prevention girders, including: rear wall frame 1, is arranged in rear wall frame 1
Window 2, the rear bumper 3 being fixed on rear wall frame 1 lower end by bolt 4 and the crashproof grid 5 formed by steel-pipe welding,
The both sides of the window 2 in described rear wall frame 1 and upper end are mounted on connecting support 6, and sleeve 7 is fixed on connection support 6, anti-
The steel tube head hitting grid 5 is inserted in sleeve 7 and is fastened by sleeve bolt.Electrokinetic cell is defined effectively by crashproof grid 5
External network chemoprevention protect, make up that the welding precision of crashproof grid 5 is low and the dimensional discrepancy that causes by the size of sleeve 7.
The impulsive force that crashproof grid 5 receives passes by connecting support 6, and its intensity is high, it is simple to assembling, versatility are good, effectively drop
Low cost.
