Abstract
The utility model discloses an electronic commercial car automobile body bottom composite beam structure, including under frame (1), the both ends of under frame (1) are provided with curb plate (2), and at two lower surfaces first stiffening beam (3) and two second stiffening beam (4) of under frame (1), the left and right both ends of every first stiffening beam (3) are connected with curb plate (2) respectively, and second stiffening beam (4) are the setting of " well " font with first stiffening beam (3), the both ends of every second stiffening beam (4) and perpendicular connection of tip of first stiffening beam (3), the lower surface of under frame (1), first stiffening beam (3) and second stiffening beam (4) form holding chamber (5) jointly. The utility model discloses make load evenly distributed that battery box or motor produced to the under frame. In addition, curb plate, first stiffening beam and second stiffening beam combined action can increase the intensity of under frame, and then reach the purpose of avoiding the automobile body skeleton to warp, guarantee driving safety.
Description
Technical field
This utility model relates to a kind of electronic commercial vehicle body bottom composite beam structure, belongs to new-energy automobile body construction technical field.
Background technology
Along with socioeconomic development, people's living standard improves constantly, the continuous adjustment of automobile industry, automotive light weight technology, electrification, intellectuality, interconnected trend grow to even greater heights, and automobile comfortableness in the process of moving and running car operability, safety be it is also proposed higher requirement by people.
Electronic commercial vehicle is when suffering from accident, and the safety of occupant is played great role by body structure.On current market, the vehicle body framework construction of commerial vehicle is difficult to take into account overall construction intensity and vehicle body deadweight problem.Electronic commercial vehicle compares conventional truck, and especially the quality weight of bottom motors and battery case, adds body bottom load, can cause Deformation of Body Framework, have a strong impact on driving safety under the long term of this load.
Utility model content
The technical problems to be solved in the utility model is: provide a kind of electronic commercial vehicle body bottom composite beam structure, strengthens the intensity of body bottom, and then reaches to avoid the purpose of Deformation of Body Framework, it is ensured that driving safety.
The purpose of this utility model is achieved through the following technical solutions:
A kind of electronic commercial vehicle body bottom composite beam structure, including underbody, a left side at underbody, right two ends are provided with side plate, lower surface at underbody is arranged at intervals with two first buttress braces, a left side for every first buttress brace, right two ends are connected with side plate respectively, lower surface at underbody is also arranged at intervals with two second buttress braces, second buttress brace and the first buttress brace are arranged in " well " font, the two ends of every second buttress brace are connected with the end vertical of the first buttress brace, the lower surface of described underbody, first buttress brace and the second buttress brace are collectively forming the containing cavity for placing battery case or motor.
Preferably, described first buttress brace arcuately structure, the height at two ends is more than the height of mid portion.Adopt bow-shaped structural, while improve the first buttress brace intensity while reducing weight, reach take into account overall construction intensity and avoid vehicle body deadweight to cause framework deformation problem.
Preferably, the two ends of every second buttress brace penetrate the end of the first buttress brace and adopt welding manner to connect, and the end face of the second buttress brace welds mutually with the lower surface of underbody.Second buttress brace penetrates to be easy in welding afterwards, it is ensured that the reliability of the first buttress brace and the welding of the second buttress brace.
Preferably, the left and right two ends of every first buttress brace adopt welding manner to be connected with side plate respectively, and the end face of the first buttress brace welds mutually with the lower surface of underbody.
By adopting technique scheme, the beneficial effects of the utility model are: be arranged on the lower surface of underbody by the first buttress brace and the second buttress brace in " well " font, and the two ends of every first buttress brace are connected with side plate respectively, first buttress brace and the second buttress brace intersect the quadrilateral area surrounded between two as the installation site of battery case or motor, so make the uniform load that battery case or motor produce be distributed on underbody.It addition, the closed-loop construct that side plate, the first buttress brace and the second buttress brace are formed increases vehicle body significantly increases the intensity of underbody, it is prevented effectively from underbody and deforms, and then reach to avoid the purpose of Deformation of Body Framework, it is ensured that driving safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Description of reference numerals: 1, underbody；2, side plate；3, the first buttress brace；4, the second buttress brace；5, containing cavity.
Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, utility model is described further:
As shown in drawings, a kind of electronic commercial vehicle body bottom composite beam structure, including underbody 1, a left side at underbody 1, right two ends are provided with side plate 2, lower surface at underbody 1 is arranged at intervals with two first buttress braces 3, a left side for every first buttress brace 3, right two ends are connected with side plate 2 respectively, lower surface at underbody 1 is also arranged at intervals with two second buttress braces 4, second buttress brace 4 and the first buttress brace 3 are arranged in " well " font, the two ends of every second buttress brace 4 are connected with the end vertical of the first buttress brace 3, the lower surface of described underbody 1, first buttress brace 3 and the second buttress brace 4 are collectively forming the containing cavity 5 for placing battery case or motor.
In the present embodiment, described first buttress brace 3 arcuately structure, the height at two ends is more than the height of mid portion.
Further, the two ends of every second buttress brace 4 penetrate the end of the first buttress brace 3 and adopt welding manner to connect, and the end face of the second buttress brace 4 welds mutually with the lower surface of underbody 1.The left and right two ends of every first buttress brace 3 adopt welding manner to be connected with side plate 2 respectively, and the end face of the first buttress brace 3 welds mutually with the lower surface of underbody 1.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, it is impossible to assert that of the present utility model being embodied as is confined to these explanations.For this utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, it is also possible to make some simple deduction or replace, protection domain of the present utility model all should be considered as belonging to.
