The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

The plastic drain pan of each embodiment of this application, through pre-buried enhancement mode material spare in the baffle between two lamp plate installation positions, plays the reinforcing action to the plastic drain pan, makes the plastic drain pan not easily crooked, strengthens anti bending capability.

It is to be understood that although in the drawings of the following embodiments, the plastic bottom chassis is described as being provided with only two lamp panel mounting positions, supporting two lamp panels mounted on the plastic bottom chassis, this should not be construed as limiting, but as an example given for convenience of description. When the plastic drain pan is provided with a plurality of lamp plate installation positions, all can pre-buried enhancement mode material spare in the baffle between two lamp plate installation positions to the anti bending ability of reinforcing plastic drain pan. Certainly, the quantity of lamp plate installation position should not too much to produce under the effect of self gravity when avoiding holding or putting to one side and warp.

The plastic bottom case of each embodiment is described in detail below with reference to the accompanying drawings.

Referring to fig. 1 and fig. 2, a schematic structural diagram of a plastic bottom case 10 according to an embodiment of the present disclosure is exemplarily shown, the plastic bottom case 10 includes a bottom case body 110 and a reinforced material 120, the reinforced material 120 is pre-embedded in the bottom case body 110; the bottom shell body 110 comprises an outer frame 111 and a plurality of partition plates 113, the outer frame 111 is provided with a plurality of outer frames 111 which surround to form a cavity, the partition plates 113 are arranged in the cavity and directly or indirectly fixedly connected to the outer frame 111 to divide the cavity into a plurality of lamp panel mounting positions 110a, and the outer frame 111 and the partition plates 113 are integrally formed by injection molding; at least one of the fixing positions of the partition 113 and the outer frame 111 is embedded with a reinforcing material 120.

When plastic drain pan 10 can include a plurality of lamp plate installation positions 110a, because the lamp plate specification of installing on plastic drain pan 10 is unanimous, therefore the specification of lamp plate installation position 110a is unanimous, consequently, the concentrated stress point of plastic drain pan 10 is located near baffle 113, through in baffle 113, baffle 113 and frame 111 the fixed department in at least one pre-buried enhancement mode material piece 120, can strengthen near baffle 113 anti bending ability, avoid plastic drain pan 10 to buckle at baffle 113 department as concentrated stress point.

For example, in the embodiment shown in fig. 1, the plastic bottom shell 10 is provided with two lamp panel mounting positions 110a, when the plastic bottom shell 10 is inclined, if the frame 111 located relatively above is not supported, the frame 111 in the upper half has a tendency to sag under the action of gravity of the frame 111 in the upper half, and meanwhile, in view of the symmetry of the plastic bottom shell 10 along the partition 113, the plastic bottom shell 10 has a tendency to half-fold, the frame 111 in the upper half generates a pulling force along the straight line of the partition 113, and reacts to bend when the strength is insufficient, by embedding the reinforced material member 120 in the partition 113 and embedding the reinforced material member 120 at the fixing position of the partition 113 and the frame 111, when the plastic bottom shell 10 generates a bending tendency, the reinforced material member 120 provides a supporting force to prevent the plastic bottom shell 10 from bending.

Referring to fig. 2, in one or more embodiments, the reinforced material 120 is embedded in the partition 113, and the length direction of the reinforced material 120 embedded in the partition 113 is perpendicular to the straight line of the partition 113. When the plastic bottom case 10 deforms, the main stress points are distributed on the straight line where the partition 113 is located, and the length direction of the reinforced material piece 120 pre-embedded in the partition 113 is set to be perpendicular to the straight line where the partition 113 is located, so that the reinforcing effect of the reinforced material piece 120 can be maximized.

Exemplarily, the both sides of baffle 113 can extend and be formed with boss 130, and boss 130 is used for fixed lamp plate, plays the supporting role to the lamp plate simultaneously, and enhancement mode material piece 120 sets up along the line of the boss 130 of baffle 113 both sides. When the bosses 130 on both sides of the partition 113 are symmetrical with respect to the partition 113, the length direction of the reinforcing bar 120 is perpendicular to the line on which the partition 113 is located.

Referring to fig. 3 and 4, the partition 113 has a first end surface 113a and a second end surface 113b opposite to each other, the first end surface 113a is provided with a first groove 140, the partition 113 is symmetrical with respect to a straight line where the first groove 140 is located, the second end surface 113b is provided with two second grooves 150, the two second grooves 150 are respectively disposed at two sides of the first groove 140 and are symmetrical with respect to the first groove 140, and the first groove 140 and the second grooves 150 are both provided with a rib 160 therein. Through setting up first slot 140 and second slot 150 to set up strengthening rib 160 in first slot 140 and second slot 150, can disperse the concentrated stress point on the baffle 113 to the bottom of strengthening rib 160 and first slot 140, realize the discrete distribution of concentrated stress point, be favorable to strengthening the anti bending capability of baffle 113 itself, thereby strengthen the anti bending capability of plastic drain pan 10.

The first trench 140 and the second trench 150 may be blind trenches, that is, the first trench 140 and the second trench 150 do not penetrate the partition 113 in the thickness direction, so as to avoid weakening the robustness of the partition 113 itself.

On the first end surface 113a, two sides of the first groove 140 may be provided with protruding ribs 1131, the two protruding ribs 1131 are disposed oppositely, a distance between the two protruding ribs 1131 is greater than a width of the first groove 140, and the reinforcing rib 160 in the first groove 140 extends outwards and is fixedly connected to the two protruding ribs 1131, so that the reinforcing rib 160 is in a T shape.
