Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
The impact protection apparatus of electrokinetic cell inclusion as shown in Figure 1; comprise the first adapter plate 1 (i.e. upper mounting plate) and the second adapter plate 2 (i.e. lower installation board); direct connection is there is not between two adapter plates; the first adapter plate 1 is wherein placed in the top of the second adapter plate 2; second adapter plate 2 slides along the lower surface of the first adapter plate 1; first adapter plate 1 is fixed on subframe, and the second adapter plate 2 is connected with body support.
The front end of the first adapter plate 1 is provided with the first mounting hole group 11, and (entirety of the first adapter plate 1 is curved, and the front end of arc is flat construction, and the first mounting hole group 11 is located at the two ends of flat construction.), as the attachment point of the first adapter plate and subframe, the first adapter plate 1 is fixed on subframe by the first mounting hole group 11.The middle part of the first adapter plate 1 is distributed with several drain gutters 12, in driving process when being splashed on adapter plate by water, can be discharged in time by these ponding by these drain gutters 12; Another effect in this hole is as structure hole, alleviates the quality of whole first adapter plate.The tail end of the first adapter plate 1 is provided with baffle plate, the front end face of baffle plate and power battery pack housing is fitted, its effect one is when a collision occurs, the first adapter plate is made to obtain a support on car load is longitudinal, when obstacle can be collided with adapter plate, the power of rum point is converted into into the power with adapter plate and battery inclusion housing Contact face, avoids the first mounting hole group 11 of the first adapter plate 1 in collision process due to stressed comparatively large and cause and come off; Next makes the area of thrust surface of electrokinetic cell inclusion increase, and makes like this to reduce impulsive force suffered in housing respective area.The both sides of baffle plate are provided with the second mounting hole group 13, for matching with car load bottom bracket, play the effect of mounting plate.In order to ensure that the second adapter plate 2 has continuity in moving process, the rear end bottom surface of the first adapter plate 1 maintains an equal level mutually with the bottom surface of electrokinetic cell inclusion, effect is in collision process, and the second adapter plate 2 can be made from the bottom surface of the first adapter plate 1 can be transitioned into the bottom surface of battery inclusion smoothly.
The roller bearing 22 that second adapter plate 2 comprises grillage 21 and is located at inside grillage 21 main body, the effect of roller bearing 22 contacts with the bottom surface of the first adapter plate 1 when battery inclusion collides, and realizes sliding.The front of grillage 21 both sides and rear are respectively equipped with second attachment point 24 (namely afterwards attachment point) of the first attachment point 23 (namely attachment point), as the installation fixed connection point of the second adapter plate and body support.First attachment point is all connected with body support with the second attachment point 24.
The bottom of grillage 1 both sides is respectively equipped with bump structure 25, the effect of this bump structure is: when the second adapter plate 2 collides with obstacle, increase the friction force between the second adapter plate 2 and obstacle, make it have enough friction force and rush open the first attachment point 23.
Further, the first attachment point 23 and the second attachment point 24 are semi-open structure, and this is the disengaging being convenient to the second adapter plate and vehicle body.
As the accessory outside electrokinetic cell inclusion, whole device is made up of upper and lower two structures, i.e. the first adapter plate and the second adapter plate, the main function of the first adapter plate is bottom car, set up a plane, the Main Function of the second adapter plate is then after colliding with obstacle, make between obstacle and car load, to form " rolling wood " of sliding, car load and obstacle are formed slide, realize being separated of obstacle and car body, and by whole slip and friction process, make impact constantly change direction and reduce.
The fixed orifice of the second adapter plate goes out to belong to half opening structure, by being connected with vehicle body in the two directions and fixing before not colliding, namely ensure that the fastness of installation, also can ensure that the second adapter plate can depart from vehicle body when colliding violent, between the first adapter plate and obstacle, forming sliding block, ensureing that battery inclusion is unlikely to impaired when there is shock.
As mentioned above; embodiment of the present utility model is explained; obviously, as long as do not depart from fact inventive point of the present utility model and effect, will be readily apparent to persons skilled in the art distortion, is also all included within protection domain of the present utility model.
