Abstract
The utility model discloses a threshold reinforcing structure for an automobile. The utility model overcomes the deficiency that the threshold of the automobile is showy and not substantial and empty inside, and provides the threshold reinforcing structure for the automobile in a compact trussed structure with large shock strength. A plurality of reinforcing plates are vertically arranged on both sides in the threshold along the threshold. A reinforcing plate supporting plate and a plurality of separators are arranged between opposite reinforcing plates. Each reinforcing plate supporting plate is connected with the reinforcing plates on both sides of the threshold. The separators are connected between both sides of the threshold according to a certain rule. As the reinforcing plates are arranged on both sides of the threshold and the reinforcing plate supporting plates and the separators are arranged, the periphery of the threshold is reinforced centrally to form an integral whole. The separators are continuously arranged inside the threshold in W shapes. The threshold as a whole is further formed as the trussed structure with large shock strength. Fewer additional parts are arranged, while the collision preventing performance is greatly improved.
Description
Technical field
The utility model belongs to the body structure technical field, is specifically related to a kind of threshold strengthening structure.
Background technology
Development along with technology, people require more and more higher to the safety performance of vehicle, in the traffic accident that occurs, the likelihood ratio that side collision occurs is higher, the injury that the occupant is caused is also larger, therefore in the development process of vehicle, to analyze design to the construction profile of car body, with the injury that reduces in accident occurs, the occupant to be caused.The multi-section rules have proposed strict requirement to the construction profile meter of car body, certainly comprise that also threshold is had strict requirement.But prior art just accomplishes to conform with laws and regulations requirement at basic aspect to the structure of threshold, has misunderstanding and resist the key element of colliding this most critical of intrusion for threshold.
China Patent No. ZL200820153346.5 for example, name is called the utility model patent of " vehicle doorsill girder ", a kind of vehicle doorsill girder is disclosed, comprise sill strip inner panel, sill strip outside plate and be arranged on brace panel assembly between sill strip inner panel and the outside plate, wherein, described brace panel assembly has the cavity girder construction, and longitudinally is fixedly mounted on the sill strip outside plate in the mode of crossing over Qianmen and back door.Because described vehicle doorsill girder adopts the cavity girder construction, when vehicle generation high-speed side is hit, can effectively reduce the intrusion amount, farthest protects occupant safety.This automobile door sill adopts the cavity girder construction, think and stay a cavity just can avoid the collision injury to hold the collision thing, this is a kind of design gaudy, stay a cavity no doubt to make the collision thing that mobile space is arranged, still, the momentum of collision thing does not but obtain decay at all, so the collision thing can be taken advantage of a weak point certainly, continue invasion, insatiable, clash towards the occupant.
Summary of the invention
The utility model technical issues that need to address are, overcome the showy and not substantial inner hollow defective of automobile door sill of prior art, and a kind of solid powerful automobile door sill reinforcing structure of truss structure, impact strength is provided.
The purpose of this utility model is achieved by following technical proposals: a kind of automobile door sill reinforcing structure, several brace panels are vertically established along threshold in both sides in the threshold, between relative brace panel, establish brace panel stay bearing plate and several dividing plates, the brace panel stay bearing plate is connected with the brace panel of both sides in the threshold, and several dividing plates distribute according to certain rules and are connected between the interior both sides of threshold.
Vertically establish several brace panels along threshold, make threshold periphery intensity enhancing; If the brace panel stay bearing plate can and connect as a whole to threshold periphery and brace panel location, several dividing plates are connected to the anti-deformation intensity that can greatly improve threshold integral body in the threshold between the both sides by certain range distribution, threshold no longer is a hollow tubular, but one is similar to the solid girder steel with enough section thicknesses and height.
As preferably, the interior shape of the shape of dividing plate and threshold section is adaptive.
As preferably, described brace panel stay bearing plate and dividing plate are provided with strengthening groove.
As preferably, if the periphery of described brace panel stay bearing plate and dividing plate respectively is provided with the lug of individual bending.
As preferably, described several dividing plates are arranged on threshold inside continuously by the W word shape, and threshold integral body is truss structure.
As preferably, described several dividing plates are arranged on threshold inside continuously by the X word shape, and threshold integral body is truss structure.
The beneficial effects of the utility model are:
1, several brace panels are established in both sides in the threshold, and establish brace panel stay bearing plate and several dividing plates, make threshold strengthen forming an integral body by the center all around;
2, dividing plate is arranged on threshold inside continuously by the W word shape, and threshold integral body further becomes truss structure, impact strength increases;
3, the part of setting up is few, and the raising of crashworthiness is not little.

The specific embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of automobile door sill reinforcing structure, brace panel 1 is vertically established along threshold in both sides in the threshold, brace panel 1 comprises that threshold brace panel 11, the interior brace panel 12 of threshold and the threshold lower-edge beam inner panel that is located on the threshold lower-edge beam inner panel 13 add brace panel 14, between relative brace panel 1, establish brace panel stay bearing plate 2 and 6 dividing plates 3, the brace panel 1 of both sides is connected in brace panel stay bearing plate 2 and the threshold, and dividing plate 3 is connected in the threshold between the both sides by certain range distribution.
Vertically establish brace panel 1 along threshold, make threshold periphery intensity enhancing; If brace panel stay bearing plate 2 can and connect as a whole to threshold periphery and brace panel 1 location, 6 dividing plates are connected to the anti-deformation intensity that can greatly improve threshold integral body in the threshold between the both sides by certain range distribution, threshold no longer is a hollow tubular shape, but one is similar to the trussed-beam steel beam with enough section thicknesses and height.
The interior shape of the peripheral shape of dividing plate 3 and threshold section is adaptive.
Brace panel stay bearing plate 2 and dividing plate 3 are provided with presses dark strengthening groove 21.
If the periphery of brace panel stay bearing plate 2 and dividing plate 3 respectively is provided with the lug 31 of individual bending.
Fig. 3 is the profile schematic perspective view of threshold, outside plate shown in the figure 4.
Embodiment 2: several dividing plates are arranged on threshold inside continuously by W or X word shape, and threshold integral body becomes the truss structure that more enriches.
The utility model can use as strengthening structure in the threshold of various automobiles, strengthen forming a truss structure integral body by the center around having the threshold of making, the advantage that impact strength increases, if those skilled in the art does simple the modification or replacement to the foregoing invention content, such change can not think to break away from scope of the present utility model, and all will be included within the scope of claim of the present utility model the apparent modification of those skilled in the art like this.
