It has broad application prospects in portable appliances, power tools, large-scale energy storage, electric transportation power supply, etc.

[0003] The existing lower plastic structure is mostly used to protect the battery tab by installing a cover on the lower plastic structure. However, the existing cover and the lower plastic body are mostly separate structures. The cover is installed on the lower plastic body when it needs to be installed. The two are also separated during the process of carrying and storing. Moreover, since the parts themselves are relatively thin, especially the cover, it is easy to cause loss, which affects subsequent use. Utility Model Content

[0023] This specific embodiment is a battery lower plastic structure, and its structural schematic diagram is as shown in Figures 1-4As shown, it includes a lower plastic body 1 and grooves 2 opened at both ends of the lower plastic body 1, and a through hole for the pole to pass through is opened on the groove 2. A cover body 3 is integrally formed at the groove 2, and the cover body 3 and one end of the groove 2 form a fold. The cover body 3 can be turned over through the fold, so that the cover body 3 and one end of the groove 2 form a rotating connection structure, and the length direction of the fold is consistent with the length direction of the lower plastic body 1, so that the rotation axis of the cover body 3 and the length direction of the lower plastic body 1 are arranged parallel to each other, ensuring the occupied space of the overall structure; one end of the cover body 3 away from the rotating part is fixedly connected to a plurality of limit assemblies, and the limit assemblies are used to limit the cover body 3 from being away from the lower plastic body 1.

[0024] The number of the limiting components is set to two, which ensures the limiting effect. The limiting components include buckles 4 that are symmetrically arranged with each other. A slot 5 for inserting the buckle 4 is provided at one end of the groove 2 away from the rotating part. The number of the slots 5 is also set to two, and the two buckles 4 in the same limiting component are inserted into one slot 5. The buckle 4 has elastic deformation potential energy that continuously fits with the inner wall of the slot 5. By setting two buckles 4, the limiting effect is further ensured.

[0025] The buckle 4 includes a deformation portion 41 extending in the thickness direction of the cover body 3 and a limiting portion 42 arranged at one end of the deformation portion 41 away from the cover body 3. A through groove 6 connected to the card slot 5 is opened at the bottom of the lower plastic body 1. The limiting portion 42 extends into the through groove 6 so that the limiting portion 42 fits with the inner bottom wall of the through groove 6. By setting the deformation portion 41, the buckle 4 can be conveniently deformed better. By setting the limiting portion 42, when the limiting portion 42 passes through the card slot 5 and extends into the through groove 6, the buckle 4 can use its own elastic deformation potential energy to cause the deformation portion 41 to fit with the inner bottom wall of the card slot 5. The side walls are fitted, and the end of the limiting portion 42 is close to the inner wall of the through groove 6 and is located below the card slot 5, so that the top of the limiting portion 42 is fitted with the inner wall of the card slot 5, and at the same time, the top of the limiting portion 42 is in contact with the inner bottom wall of the through groove 6, thereby limiting the cover body 3 from being away from the lower plastic body 1, so that the cover body 3 is fixed in the corresponding position; a guide surface is provided at the end of the side of the limiting portion 42 away from the cover body 3, and the guide surface has a good guiding effect. When closing the cover body 3, the cover body 3 can be pressed directly, and the buckle 4 generates a component force effect through the guiding action of the guide surface to deform.

[0026] A plurality of insertion openings 7 for fingers to extend into are formed in the cover body 3. The limiting component is located between two adjacent insertion openings 7. The inner side walls of two adjacent insertion openings 7 facing each other and one side of two adjacent buckles 4 facing each other are located on the same plane. By providing the insertion openings 7, fingers can be extended into the insertion openings 7 to press the deformation part 41 of the buckle 4 to cause it to deform. One end of the cover body 3 away from the rotating part is fixedly connected with a supporting part 9. A notch 8 for the supporting part 9 to be inserted into is formed on the lower plastic body 1 on the side of the groove 2 away from the rotating part. The clamping groove 5 is formed at the notch 8. When the cover body 3 is closed, the supporting part 9 is attached to the top of the lower plastic body 1, so that a certain distance is formed between the cover body 3 and the clamping groove 5, thereby ensuring the length of the deformation part 41 outside the clamping groove 5, and making it more convenient for a human hand to extend into the insertion opening 7 to press the deformation part 41.

[0027] Working principle: The battery pole is passed through the through hole from the bottom of the lower plastic body 1 and extends into the groove 2. At this time, since the cross-sectional area of the battery pole is larger than that of the through hole, the battery pole is pressed against the inner bottom wall of the groove 2 to prevent the lower plastic body 1 from separating from the battery. At this time, welding work is carried out on the pole. After welding is completed, the cover body 3 is folded, the limiting component is aligned with the clamping groove 5, and the buckle 4 is inserted into the clamping groove 5. The guiding surface of the limiting part 42 of the buckle 4 first contacts the inner side wall of the clamping groove 5. The cover body 3 is continuously pressed, and the buckle 4 deforms under the external force, so that the two buckles 4 in the same limiting component approach each other. When the cover body 3 is completely closed, the limiting part 42 of the buckle 4 extends into the through groove 6. At this time, the buckle 4 returns to its original state through its own elasticity, so that the two buckles 4 move away from each other, and the limiting part 42 of the buckle 4 extends below the clamping groove 5, so that the limiting part 42 contacts the inner bottom wall of the through groove 6. At this time, the limiting part 42 is used to limit the cover body 3 away from the lower plastic body 1, so that the cover body 3 is fixed in the corresponding position, better protecting the battery pole ear. And the cover body 3 and the lower plastic body 1 are formed into an integrally formed structure, making the overall lower plastic structure more convenient to carry and not easily lost. And through the setting of the limiting component, the assembly of the cover body 3 and the lower plastic body 1 is more convenient and fast. When the cover body 3 needs to be opened, fingers extend into the insertion opening 7, and the two buckles 4 can be pinched, so that the two buckles 4 approach each other, and the limiting part 42 moves away from the side wall of the through groove 6 and corresponds to the clamping groove 5. At this time, the cover body 3 can be easily opened in the direction away from the lower plastic body 1.

[0028] All the technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are the preferred implementation solutions of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution is within the protection scope of the present invention.
