Detailed Description

The present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1 to 4, a high-strength anti-fracture battery handle structure includes an outer bag body 1 and a reinforcement body 2 disposed inside the outer bag body 1, wherein the outline structure of the reinforcement body 2 is contoured on the outer bag body 1, and both the reinforcement body 2 and the reinforcement body are U-shaped curved structures, the reinforcement body 2 is embedded inside the outer bag body, the outer bag body 1 and the reinforcement body 2 both include a handle portion and mounting portions disposed at both ends of the handle portion, and the outer bag body 1 and the reinforcement body 2 are directly or indirectly connected to a carrier through the mounting portions thereof.

The handle structure not only contains the inclusion 1, still through having increased the reinforcement 2 as inside intermediate layer, support as inside through the reinforcement, make handle structural strength more reliable, can not split, and because the inclusion is connected simultaneously with the reinforcement and is installed on the carrier, even the outer inclusion of handle appears colliding with the damage, the fracture, the effect of handle still can be maintained to inside reinforcement, avoid the complete separation of battery case and handle, guarantee the security of battery, on the other hand, under the outer inclusion damaged condition of handle, because the adhesion effect that the reinforcement increases, can reduce the damaged degree of outer inclusion plastics.

The reinforcement body 2 is of an integrated plate structure, and the outer bag body 1 is wrapped on the outer side of the reinforcement body 2 in an injection molding mode. The reinforcement body 2 is made of metal, and the outer bag body 1 is made of plastic. Through the sheet metal construction of the parcel of moulding plastics of an organic whole in the middle of the alloy plastics handle, can realize multiple handle molding design, improve and hold sense and aesthetic feeling, promote its handle intensity simultaneously.

When the product is designed, after the structural design of the outer package body of the handle is finished, a profiling inner sheet metal structure, namely the reinforcing body 2, is designed. When the preparation, place in moulding a handle mould through the sheet metal construction with the profile modeling in advance, then carry out injection moulding, realize moulding plastics integrated into one piece, the metal construction can not be seen to the outward appearance, does not influence pleasing to the eye and holds the sense.

The reinforcement body 2 contains the enhancement handle portion 3 and sets up the enhancement installation department 4 on strengthening the handle portion both ends, strengthen the handle portion 3 and be the curved surface structure in length direction's cross-section, through the curved surface structure, can increase the area of contact between the outer inclusion 1 and the reinforcement body 2, increase both adhesive strength.

Strengthen the handle portion 3 and include at least one strengthening rib 5 in the width direction, just the length direction of strengthening rib 5 is unanimous with the length direction of reinforcement body handle portion 3, the reinforcement body 2 is metal stamping forming structure, just strengthening rib 5 and the integrative stamping forming of strengthening the handle portion. The reinforcing ribs 5 can increase the bending strength and the torsional strength of the reinforcing body 2, and further improve the overall anti-fracture performance of the handle.

The body of the reinforcing handle part 3 is provided with a plurality of through holes 6 in a penetrating way, the inner part of the outer bag body 1 corresponding to the through holes 6 comprises penetrating pins, when the outer bag body 1 is in injection molding, the parts corresponding to the through holes 6 form the penetrating pins after hardening, the connecting strength of the outer bag body and the reinforcing body is increased, the relative position stability of the outer bag body and the reinforcing body is increased, and the outer bag body and the reinforcing body are prevented from being separated in the using process.

Strengthen installation department 4 is the lamellar plate body structure, just strengthen and seted up mounting hole 8 on the installation department 4. The outer bag body 1 comprises an outer bag handle part 11 corresponding to the reinforcing handle part 3 and an outer bag installation part 12 corresponding to the reinforcing installation part 4, and a mounting hole II 9 is formed in the outer bag installation part 12 in a penetrating mode corresponding to the first mounting hole 8. The first mounting hole 8 and the second mounting hole 9 correspond to each other and are used for penetrating screws, and the outer bag body and the reinforcement body are simultaneously connected to the carrier through the first mounting hole and the second mounting hole.

The reinforcement body 2 is made of metal, and the outer bag body 1 is made of plastic.

The inside wall of outsourcing handle portion of outsourcing portion 1 goes up the concave a plurality of antiskid groove 7 that are equipped with, and the inboard of outsourcing portion is the one side towards the carrier, and a plurality of antiskid groove 7 distributes in the width direction. Can reduce the consumption volume of the plastics of outer inclusion on the one hand through antiskid groove 7, save the cost, weight reduction, on the other hand, through the frictional force of antiskid groove 7 increase when using, promote the safety in utilization.

The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
