As shown in fig. 1, the present invention provides an electric vehicle, which mainly includes a vehicle body 110, a battery pack 120, a sliding rail assembly 130 and a limiting member 140. The vehicle body 110 is disposed in the lateral direction, and the battery pack 120 is disposed at the bottom of the vehicle body 110 in the lateral direction. The rail assembly 130 is disposed at a side portion of the battery pack 120 in a lateral direction, and can be connected to the vehicle body 110 and the battery pack 120, respectively. The limiting member 140 is disposed at an end of the sliding rail assembly 130 for limiting the battery pack 120. Since other structures of electric vehicles are known in the art, they are not described in detail for the sake of simplicity.
As shown in fig. 2 to 5, the slide rail assembly 130 includes a first slide rail 131 and a second slide rail 132 slidably connected to the first slide rail 131, the first slide rail 131 and the battery pack 120 may be connected by a fastener, and the second slide rail 132 and the vehicle body 110 may be connected by a fastener, so that the battery pack 120 can move relative to the vehicle body 110. In the present embodiment, the first slide rail 131 and the second slide rail 132 each extend in the width direction W of the vehicle body 110, so that the battery pack 120 can slide in the width direction W of the vehicle body 110. In one embodiment, not shown, the first slide rail is connected to the vehicle body and the second slide rail is connected to the battery pack.
The limiting members 140 are disposed at corresponding end portions of the first slide rail 131 and the second slide rail 132, and two ends of the limiting members 140 are connected to the first slide rail 131 and the second slide rail 132 through fasteners, respectively, so as to limit relative sliding between the first slide rail 131 and the second slide rail 132, thereby mounting the battery pack 120 at a predetermined position of the vehicle body 110. Preferably, the limiting member 140 is a coiled plate spring. The position-limiting member 140 may also be a spring or other elastic structure, as desired.
In the present embodiment, when the limiting member 140 is not deformed, the relative sliding between the first slide rail 131 and the second slide rail 132 can be limited, and when the force applied to the limiting member 140 is equal to or greater than a predetermined value, the limiting member 140 can be deformed, so that the first slide rail 131 and the second slide rail 132 can slide relative to each other, and further the battery pack 120 can slide relative to the vehicle body 110, and when the limiting member 140 is in the maximum deformation state, the maximum relative sliding distance between the first slide rail 131 and the second slide rail 132 can be limited. Preferably, the maximum relative sliding distance is 90mm to 110 mm. Therefore, when the electric vehicle collides, the battery pack 120 can apply a tensile force to the stopper 140 by the collision force, so that the stopper 140 can be deformed, and the battery pack 120 can slide to the non-collision side with respect to the vehicle body 110 to avoid the collision region, thereby reducing the possibility of damage to the battery pack 120.
As shown in fig. 1, the electric vehicle of the present embodiment includes two slide rail assemblies 130 and four limiting members 140, and the four limiting members 140 are respectively disposed at two ends of the two slide rail assemblies 130. The two slide rail assemblies 130 are spaced apart along the length direction L of the vehicle body 110 and are disposed on opposite sides of the battery pack 120. Therefore, when the electric vehicle undergoes a side pillar collision, the battery pack 120 can slide with respect to the vehicle body 110 in the width direction W of the vehicle body 110 toward the non-collision side.
As shown in fig. 5 and 6, the second slide rail 132 is disposed inside the first slide rail 131 in the longitudinal direction of the first slide rail 131 (i.e., the width direction W of the vehicle body 110). In this embodiment, the second slide rail 132 is an inner slide rail, and the first slide rail 131 is an outer slide rail engaged with the inner slide rail. More specifically, the first slide rail 131 may be provided with two inner slides 133 extending along a length direction thereof, and both sides of the second slide rail 132 are provided with flanges 134 extending along a length direction thereof, the flanges 134 extending into the inner slides 133 and being capable of sliding along a length direction of the inner slides 133.
Under normal conditions, for example, when the vehicle runs normally, the limiting member 140 does not fail, and the ends of the first slide rail 131 and the second slide rail 132 can be connected together to limit the first slide rail 131 from sliding relative to the second slide rail 132, so that the battery pack 120 does not slide relative to the vehicle body 110.
When the electric vehicle has a side pillar collision and the collision force applied to the battery pack 120 is equal to or greater than 200KN, the limiting member 140 is deformed and unfolded by the pulling force applied to the limiting member 140 by the battery pack 120, and may even be straightened, so that the battery pack 120 can slide relative to the vehicle body 110 along the width direction W of the vehicle body 110 to the non-collision side, and the limiting member 140 can restrain the degrees of freedom of the battery pack 120 in other directions.
As shown in fig. 1 and 3, the battery pack 120 includes a battery module 121, a battery case 122 covering at least an outer periphery of the battery module 121, and lugs 123 provided on opposite sides of the battery case 122 in the longitudinal direction L of the vehicle body 110. The number of the lifting lugs 123 of the present embodiment is four, two of which are disposed at one side of the battery case 122 with an interval therebetween, and the other two of which are disposed at the other side of the battery case 122 with an interval therebetween. The lifting lug 123 is connected to the battery case 122 and the first slide rail 131, respectively. For example, the lifting lug 123 may be integrally formed with the battery case 122, or may be welded to the battery case 122, or may be connected to the battery case 122 by a fastener. The lifting lug 123 may be connected to the first slide rail 131 by a fastener to connect the first slide rail 131 to the battery pack 120. It will be understood by those skilled in the art that the number of the lifting lugs 123 is not limited to the embodiment, and the number of the lifting lugs may be two, six or any other suitable number according to the requirement.
As shown in fig. 1 and 2, the vehicle body 110 includes a pair of side members 111, a pair of cross members 112 disposed between the pair of side members 111, and a floor 113. The pair of side members 111 are provided along the longitudinal direction L of the vehicle body 110, and are spaced apart from each other in the width direction W of the vehicle body 110. The pair of cross members 112 are provided along the width direction W of the vehicle body 110, and are provided at intervals along the longitudinal direction L of the vehicle body 110. The floor 113 is disposed between the pair of cross members 112 in the longitudinal direction L of the vehicle body 110, and between the pair of side members 111 in the width direction W of the vehicle body 110.
The second slide rails 132 of the two slide rail assemblies 130 are respectively disposed below the pair of cross members 112 and connected to the pair of cross members 112 by fasteners. The battery pack 120 is disposed below the floor panel 113 and is disposed between the pair of side members 111 at an interval. The battery pack 120 is spaced apart from the side member 111 by a predetermined distance, which is greater than a maximum relative sliding distance between the first slide rail 131 and the second slide rail 132, so as to prevent the battery pack 120 from colliding with the side member 111 when sliding in the width direction of the vehicle body 110.
According to the utility model discloses an electric automobile, when electric automobile bumps, the battery package can exert the pulling force to the locating part under the effect of collision force, can take place deformation when the power that the locating part received is greater than or equal to the predetermined value for can take place relative slip between first slide rail and the second slide rail, and then make the battery package slide to non-collision side for the automobile body, consequently can avoid the striking region, thereby reduce the possibility that the battery package damaged. In addition, the limiting member can limit the maximum relative sliding distance between the first slide rail and the second slide rail, and can restrict the degree of freedom of the battery pack in other directions.
