Description

Technical Field

[0001] The utility model belongs to the technical field of logistics transport vehicles, and in particular relates to a detachable anti-deformation reinforcement structure for an electric core frame. Background Art

[0002] With the development of the new energy industry, the demand for on-site and off-site transportation logistics vehicles for battery cells is increasing. Injection-molded logistics baskets are widely used as transportation vehicles for battery cells because of their light weight, good toughness, and impact resistance. Due to the shrinkage properties of plastic itself, after the outer frame of the injection-molded logistics basket is injection-molded, the two side panels will have a concave phenomenon, resulting in a smaller external dimension, affecting the lining and the assembly of subsequent batteries. When using injection-molded logistics baskets to transport or store batteries, the injection-molded logistics baskets are usually stacked in multiple layers to save space. After the outer frame is stacked and stressed, the side panels of the outer frame will bulge outward due to the pressure from above, resulting in a convex phenomenon, resulting in a larger external dimension. In order to solve this problem, the existing method is usually to set more dense injection-molded reinforcement ribs on the outer frame, or to increase the thickness of the outer frame to obtain higher strength, but this method will increase the weight of the frame, increase the consumption of injection molding raw materials, increase production costs, and cannot completely solve the impact of the shrinkage characteristics of plastics on the size of the logistics basket. Summary of the invention

[0003] In view of the above problems and technical requirements, the utility model provides a detachable anti-electrode core frame deformation reinforcement structure, which can resist the inward or outward deformation of the side plates of the logistics basket and improve the mechanical strength of the logistics basket.

[0004] The technical solution of the utility model is as follows: a detachable anti-deformation reinforcement structure for the electric core frame, including a logistics basket and a metal reinforcement strip. The logistics basket is rectangular and includes a bottom plate, a side panel and an end panel. The size of the side panel is larger than that of the end panel. One or more card slots are provided on the outer side of the side panel, each of which is parallel to the bottom plate. The metal reinforcement strip is detachably installed in the card slot; the metal reinforcement strip is a flat straight strip, and the metal reinforcement strip is horizontally inserted into the card slot. The wide side of the metal reinforcement strip remains horizontal, and the narrow side of the metal reinforcement strip remains vertical, and the narrow side faces inward and is inserted into the card slot accordingly. The metal reinforcement strip is detachably connected to the card slot, which does not affect the injection molding process of the logistics basket itself. When the metal reinforcement strip is damaged, deformed or rusted after long-term use, it can be replaced in time. When the logistics basket is scrapped and recycled, the metal reinforcement strip can be disassembled to facilitate the separate recycling of the two materials.

[0005] Furthermore, nuts are fixedly connected at both ends of the metal reinforcement strip, blind holes are provided on the side panels on both sides of the slot, screw holes are provided in the center of the blind holes, and embedded nuts are provided at the bottom of the blind holes. After the metal reinforcement strip is embedded in the slot, the nuts at both ends are correspondingly embedded in the blind holes on both sides, the nuts and the embedded nuts are opposite, and a fixing screw is inserted into the screw hole to lock and connect the nuts and the embedded nuts. The metal reinforcement strip is fixedly installed on the side panel by the nut, and the nut is accommodated in the blind hole so that there is no protrusion on the surface of the chassis. Since the metal reinforcement strip is easy to damage the chassis after repeated disassembly and assembly, an embedded nut is provided in the blind hole, and the nut and the embedded nut are connected by the fixing screw, which can ensure that the connection is still tight after multiple disassembly and assembly, and will not cause damage to the chassis.

[0006] Furthermore, a row of slots is provided in the middle and upper parts of the side panels, and one metal reinforcement strip or a plurality of metal reinforcement strips can be installed in each slot. The metal reinforcement strips are manufactured in batches with fixed sizes, while the logistics baskets have various sizes. During installation, the number of metal reinforcement strips to be installed is selected according to the size of the logistics baskets.

[0007] Furthermore, a metal reinforcement strip parallel to the bottom plate is also inlaid and installed on the end panel of the logistics basket.

[0008] Furthermore, the logistics basket is made of plastic, the bottom plate, the side panel and the end panel are integrally formed by injection molding, and the metal reinforcement strip is made of stainless steel.

[0009] Furthermore, the side panel is provided with a plurality of hollow slots, and the hollow slots are staggered with the card slots.

[0010] Furthermore, an inner lining strip is installed in the logistics basket, and the battery core workpieces are stored in the inner lining strip.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows: installing metal reinforcement strips on the sides of the basket body of the logistics basket can improve the supporting strength of the side panels, avoid inward shrinkage of the side panel plastic after injection molding, and outward bulging of the side panels after stacking and compression; the metal reinforcement strips are flat, and the narrow side of the metal reinforcement strips is inserted into the slot. Since the force direction is horizontally inward or outward, that is, the force surface acts on the narrow surface, and the thickness of the metal resisting the force is the width of the wide surface, the metal reinforcement strip is not easy to deform under force, and the flat metal reinforcement strip has a lighter weight, and the logistics basket does not need to be additionally thickened to resist deformation. Therefore, the logistics basket inlaid with metal reinforcement strips can still remain light, saving materials and production costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-6 The figure shows a detachable anti-deformation reinforcement structure of the electric core frame of the utility model, including a logistics basket 1 and a metal reinforcement strip 5. The logistics basket 1 is rectangular and includes a bottom plate 2, a side panel 3 and an end panel 4. The size of the side panel 3 is larger than that of the end panel 4. One or more slots 31 are provided on the outer side of the side panel 3, and each slot 31 is parallel to the bottom plate 2. The metal reinforcement strip 5 is detachably installed in the slot 31.

[0021] The logistics basket 1 is provided with an inner lining strip 12, and the inner lining strip 12 contains a battery workpiece 13. The side panel 3 is provided with a plurality of hollow slots 11, and the hollow slots 11 are staggered with the slots 31. The logistics basket 1 is made of plastic, and the bottom plate 2, the side panel 3 and the end panel 4 are integrally injection molded parts, and the metal reinforcement strip 5 is made of stainless steel. The metal reinforcement strip 5 is detachably connected to the slot 31, which does not affect the injection molding process of the logistics basket 1 itself. When the metal reinforcement strip 5 is damaged, deformed or rusted after long-term use, it can be replaced in time. When the logistics basket is scrapped and recycled, the metal reinforcement strip can be disassembled to facilitate the separate recycling of the two materials.

[0022] The metal reinforcement strip 5 is a flat straight strip, and the metal reinforcement strip 5 is horizontally inserted into the slot 31, with the wide surface 51 of the metal reinforcement strip 5 kept horizontal, and the narrow surface 52 of the metal reinforcement strip 5 kept vertical, and the narrow surface 52 is inserted into the slot 31 inwardly. When the narrow surface of the metal reinforcement strip 5 is inserted into the slot 31, since the force direction is horizontally inward or outward, that is, the force surface acts on the narrow surface 52, and the thickness of the metal resisting the force is the width of the wide surface, the metal reinforcement strip 5 is not easily deformed under force.

[0023] The two ends of the metal reinforcement strip 5 are fixedly connected with nuts 53, blind holes 32 are provided on the side panels on both sides of the slot 31, screw holes 321 are provided in the center of the blind holes 32, and embedded nuts 322 are provided at the bottom of the blind holes 32. After the metal reinforcement strip 5 is embedded in the slot 31, the nuts 53 at both ends are correspondingly embedded in the blind holes 32 on both sides, and the nuts 53 and the embedded nuts 322 are opposite. A fixing screw 6 is inserted into the screw hole 321 to lock and connect the nuts 53 and the embedded nuts 322. The metal reinforcement strip 5 is fixedly installed on the side panel 3 by the nuts 53, and the nuts 53 are accommodated in the blind holes 32 so that there is no protrusion on the surface of the housing. Since the metal reinforcement strip 5 is easy to damage the housing after repeated disassembly and assembly, an embedded nut 322 is set in the blind hole 32, and the nuts 53 and the embedded nuts 322 are connected by the fixing screw 6, which can ensure that they are still tightly connected after multiple disassembly and assembly, and will not cause damage to the housing.

[0024] The middle and upper parts of the side panels 3 are provided with a row of slots 31, respectively. One metal reinforcing strip 5 or multiple metal reinforcing strips 5 can be installed in a row of slots 31. The metal reinforcing strips 5 are manufactured in batches with fixed sizes, while the logistics basket 1 has various sizes. During installation, the number and installation method of the metal reinforcing strips are selected according to the size of the logistics basket. The end panel 4 of the logistics basket 1 can also be inlaid with a metal reinforcing strip 5 parallel to the bottom plate 2, so that the strength of the basket will be further enhanced.

[0025] The application principle of the utility model is as follows: a metal reinforcing strip 5 is embedded and installed on the upper and middle parts of the side or end faces of the logistics basket 1, and the flat metal reinforcing strip 5 is horizontally inserted into the slot 31 reserved on the side face of the basket, which is equivalent to adding a detachable rib position on the side face of the basket. The mechanical strength of the metal provides a stronger support for the basket to prevent the basket from being deformed by being sunken inward or bulging outward. The installation method of horizontally inserting into the slot 31 makes the force-bearing surface act on the narrow surface 52 of the metal reinforcing strip. The thickness of the metal reinforcing strip 5 in the horizontal direction can resist deformation. If the wide surface 52 is embedded, the thickness in the horizontal direction is very thin, so that the metal reinforcing strip 5 can be easily deformed together with the basket. Therefore, the logistics basket 1 installed by this scheme has the characteristics of light weight, low production cost, and high mechanical strength to resist deformation.

[0026] The above are only several preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes and substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
