Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, specifically to a battery compartment and a mobility scooter. Background Technology

[0002] In related technologies, the bottom of the battery compartment of electric vehicles is basically flat or has grooved patterns. Although it is easy to manufacture, its rigidity is low and it is easy to deform after impact. At this time, the bottom plate of the battery compartment not only affects the flatness of the installation of the battery and plastic parts inside the battery compartment, but also makes the battery easy to be pressed by the bottom plate, thus affecting its safety of use. Utility Model Content

The base plate includes a plate body and reinforcing ribs defining the pressure grooves. The inclination angle of the side of the pressure groove is α, wherein 30°≤α≤60°.

[0007] According to the battery compartment of this utility model embodiment, by setting a groove on the upper surface of the bottom plate to form a plate and a reinforcing rib protruding below the body, and limiting the inclination angle of the side of the groove to between 30° and 60°, when the bottom plate is subjected to external impacts in the vertical and horizontal directions, the peripheral wall of the side of the groove formed in the reinforcing rib is less likely to bend and deform relative to the bottom wall of the plate and the bottom surface of the groove formed in the reinforcing rib. That is, the reinforcing rib can withstand greater impacts from the vertical and horizontal directions without deformation, thereby effectively improving the overall rigidity and flatness of the top surface of the bottom plate, and the bottom plate provides better protection for the battery and plastic parts inside the battery compartment.

On a projection plane perpendicular to the first direction, the projection of the first reinforcing rib coincides with the projection of the second reinforcing rib. On a projection plane perpendicular to the second direction, the projection of the first reinforcing rib coincides with the projection of the second reinforcing rib. The second direction, the first direction, and the thickness direction of the plate are perpendicular to each other.

[0012] In some embodiments, on a projection plane perpendicular to the first direction, the projection of the second reinforcing rib coincides with the projection of the first reinforcing rib, and on a projection plane perpendicular to the second direction, the projection of the second reinforcing rib coincides with the projection of the first reinforcing rib.

[0024] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0025] The following is combined with Figure 1 and Figure 2 The battery compartment according to an embodiment of the present utility model is described.

[0026] The battery compartment of this utility model embodiment includes a base plate 1. The upper surface of the base plate 1 is provided with a plurality of pressure grooves 15. The base plate 1 includes a plate body 11 and reinforcing ribs that define the pressure grooves 15. The inclination angle of the side of the pressure groove 15 is α, wherein 30°≤α≤60°.

[0027] According to the battery compartment of this utility model embodiment, by providing a groove 15 on the upper surface of the base plate 1 to form a plate 11 and a reinforcing rib protruding below the body, and limiting the inclination angle of the side of the groove 15 to between 30° and 60°, when the base plate 1 is subjected to external impacts in the vertical and horizontal directions, the peripheral wall of the side of the groove 15 formed in the reinforcing rib is less likely to bend and deform relative to the bottom wall of the plate 11 and the bottom surface of the groove 15 formed in the reinforcing rib. That is, the reinforcing rib can withstand greater impacts from the vertical and horizontal directions without deformation, thereby effectively improving the overall rigidity and flatness of the upper surface of the base plate 1, and the base plate 1 provides better protection for the battery and plastic parts inside the battery compartment.

[0028] It should be noted that the inclination angle α of the side of the pressure groove 15 can be 30°, 45° and 60°.

[0029] In some embodiments, the bottom surface of the groove 15 is provided with a through hole 16, which extends along the depth direction of the groove 15 and passes through the reinforcing rib.

[0030] The through-hole 16 serves two purposes. First, it effectively prevents stress concentration in the reinforcing ribs, which could lead to premature instability under impact, thereby further improving the rigidity of the reinforcing ribs and enhancing the deformation resistance of the base plate 1. Second, it facilitates the drainage of water from the base plate 1 to the outside when water accumulates on it, preventing prolonged water retention that could corrode the base plate 1 and affect its service life.

[0031] For example, such as Figure 1 and Figure 2As shown, through holes 16 are provided on the bottom wall of the reinforcing ribs, and some of the smaller reinforcing ribs have one through hole 16 on their bottom wall, while other larger reinforcing ribs have two or three through holes 16 on their bottom wall.

[0032] In some embodiments, the peripheral wall of the reinforcing rib transitions to the plate 11 with an arc, and the peripheral wall of the reinforcing rib transitions to the bottom wall of the reinforcing rib with an arc.

[0033] This further avoids stress concentration at the reinforcing ribs and their connection with the plate 11, thereby effectively preventing premature instability at stress concentration points and reducing the rigidity of the base plate 1. The base plate 1 provides better protection for the battery and plastic parts inside the battery compartment.

[0034] For example, such as Figure 2 As shown, the outer and inner surfaces of any reinforcing rib include arc surfaces, which are used to smoothly connect with adjacent planes or arc surfaces.

[0035] In some embodiments, there are multiple sets of reinforcing ribs, which are spaced apart along a first direction of the plate 11.

[0036] By dividing the reinforcing ribs into multiple groups, the distribution pattern of each reinforcing rib is made easier to form, while also ensuring high rigidity consistency in each area of ​​the base plate 1 and high reliability of the support for the battery and plastic parts in each area of ​​the base plate 1.

[0037] For example, such as Figure 1 and Figure 2 As shown, the first direction is the length direction of the plate 11, and there are three sets of reinforcing ribs arranged at equal intervals along the first direction.

[0038] In some embodiments, each set of reinforcing ribs includes a first reinforcing rib 12 and a second reinforcing rib 13. On a projection plane perpendicular to the first direction, the projection of the first reinforcing rib 12 coincides with the projection of the second reinforcing rib 13. On a projection plane perpendicular to the second direction, the projection of the first reinforcing rib 12 coincides with the projection of the second reinforcing rib 13. The second direction, the first direction, and the thickness direction of the plate 11 are perpendicular to each other.

[0039] Therefore, in each set of reinforcing ribs, there will be no unstable inertial axis (virtual axis located between the first reinforcing rib 12 and the second reinforcing rib 13) extending along the first direction and the second direction. Consequently, when the base plate 1 is subjected to an impact from the first direction or the second direction, it is less likely to bend and deform under the mutual support of the first reinforcing rib 12 and the second reinforcing rib 13, and the base plate 1 has higher rigidity.

[0040] For example, such as Figure 1 As shown, the first reinforcing rib 12 and the second reinforcing rib 13 are generally strip-shaped reinforcing ribs, and their extension directions intersect and are generally arranged in an X-shape.

[0041] In some embodiments, on a projection plane perpendicular to the first direction, the projection of the second reinforcing rib 13 coincides with the projection of the first reinforcing rib 12; on a projection plane perpendicular to the second direction, the projection of the second reinforcing rib 13 coincides with the projection of the first reinforcing rib 12. In each group of reinforcing ribs, there are two second reinforcing ribs 13 arranged at intervals on opposite sides of the first reinforcing rib 12 along its width direction.

[0042] Therefore, with the combined support of the first reinforcing rib 12 and the second reinforcing rib 13, the base plate 1 has higher impact resistance in the horizontal direction and higher reliability in supporting the battery and plastic parts. Furthermore, by splitting the second reinforcing rib 13 into two and arranging them on both sides of the width of the first reinforcing rib 12, the rigidity of the base plate 1 is ensured, while the molding difficulty of the first reinforcing rib 12 and the second reinforcing rib 13 is also effectively reduced.

[0043] For example, such as Figure 1 and Figure 2 As shown, the two second reinforcing ribs 13 extend in roughly the same direction. The second reinforcing ribs 13 and the first reinforcing ribs 12 are arranged alternately to effectively avoid local instability caused by stress concentration due to their intersection.

[0044] In some embodiments, each group of reinforcing ribs further includes a plurality of third reinforcing ribs 14, wherein the groove 15 defined by the third reinforcing ribs 14 is at least one of a circle, an ellipse, and an irregular shape, and on the projection plane perpendicular to the thickness direction of the plate body 11, the projected area of ​​the third reinforcing rib 14 is smaller than the projected area of ​​the first reinforcing rib 12 and the projected area of ​​the second reinforcing rib 13.

[0045] By setting a smaller third reinforcing rib 14 near the location where wrinkles are likely to occur, the deformation resistance at this location can be effectively reduced, thereby further improving the rigidity of the base plate 1 and better ensuring the flatness of the upper surface of the base plate 1.

[0046] For example, such as Figure 1 and Figure 2 As shown, each set of reinforcing ribs includes two third reinforcing ribs 14 that define circular grooves 15 and two third reinforcing ribs 14 that define irregular shapes of grooves 15, with a total of four third reinforcing ribs 14 arranged in a rhomboid shape.

[0047] In some embodiments, the groove 15 defined by the first reinforcing rib 12 is straight or curved, and the groove 15 defined by the second reinforcing rib 13 is also straight or curved. This arrangement improves the bending strength of the first reinforcing rib 12 and the second reinforcing rib 13 while effectively reducing the molding difficulty of the first reinforcing rib 12 and the second reinforcing rib 13.

[0048] For example, such as Figure 1 and Figure 2 As shown, the groove 15 defined by each of the first reinforcing rib 12 and the second reinforcing rib 13 is curved.

[0049] In some embodiments, the battery compartment further includes multiple support strips connected to the plate 11, and the multiple support strips and multiple sets of reinforcing ribs are arranged alternately along a first direction.

[0050] By setting a support strip connected to the plate 11 between any two adjacent sets of reinforcing ribs, the rigidity of the area between any two adjacent sets of reinforcing ribs is effectively improved with the auxiliary support of the support strip, and the base plate 1 provides better protection for the battery and plastic as a whole.

[0051] For example, such as Figure 1 and Figure 2 As shown, there are three support strips arranged at equal intervals along the first direction, and the support strips are welded to the plate 11.

[0052] In some embodiments, the base plate 1 further includes a folded edge 17, which is disposed on the edge of the plate body 11 and extends circumferentially along the plate body 11.

[0053] The folded edge 17 effectively improves the bending strength of the edge of the plate 11, thereby making the upper surface of the plate 11 flatter and providing better protection for the battery and plastic.

[0054] For example, such as Figure 1 and Figure 2 As shown, the two long sides of the plate 11 are provided with folded edges 17, and one of the short sides of the plate 11 is provided with folded edges 17. The folded edges 17 at the long side are welded to the folded edges 17 at the short side.
