Description

Technical Field

[0001] This utility model relates to the field of mechanical technology, and more specifically to a novel type of plastic. Background Technology

[0002] The existing battery cover is composed of a metal substrate and an insulating plastic layer, with the plastic layer fixed to the bottom of the substrate.

[0003] Existing plastic substrates are generally long sheets with a one-piece structure. After injection molding and cooling, the plastic substrate shrinks, and the larger the substrate, the greater the shrinkage. This affects the pre-designed dimensions, making it difficult or even impossible to install on the substrate, resulting in scrap. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by providing a novel, highly adaptable plastic material.

[0005] To achieve the above objectives, this utility model can be implemented through the following technical solutions:

[0006] A novel type of plastic includes a long sheet-shaped body, characterized in that the middle of the body has a plurality of through deformation holes along its width direction, a non-linear deformation segment is formed between two adjacent deformation holes, and the plurality of deformation segments form a deformation part in the middle of the body that can deform under the action of external force.

[0007] In the aforementioned novel plastic, the body has a grid-like pressure relief section in the middle, and the aforementioned deformable section is adjacent to the pressure relief section.

[0008] In the aforementioned novel plastic, the deformation segment is V-shaped, with the middle part of the body width direction as the reference, and the left and right sides of the body width direction are respectively deformation region one and deformation region two. The opening direction of the deformation segment in deformation region one is opposite to the opening direction of the deformation segment in deformation region two.

[0009] In the aforementioned novel lower plastic, the opening direction of the deformable segment faces the outer edge of the adjacent body.

[0010] In the aforementioned novel plastic, the width of the deformable segment matches the thickness of the body.

[0011] In the aforementioned novel plastic, the V-shaped angle of the deformed segment has a smoothly transitioning rounded corner.

[0012] In the aforementioned novel lower plastic, a reinforcing portion is provided between the outer side of the deformed section end and the body.

[0013] In the aforementioned novel plastic, the reinforcing part is a transition part that smoothly transitions between the outer end of the deformable section and the body.

[0014] In the aforementioned novel plastic, the connection between the reinforcing part, the outer end of the deformation section and the body is a rounded transition.

[0015] In the aforementioned novel plastic, the main body, the pressure relief section, and the deformation section are all integral structures.

[0016] Compared with existing technologies, the length of the lower plastic body after preparation may not meet the preset standard size; that is, the length of the body may be too long or too short. However, the lower plastic body of this invention creatively incorporates several deformation segments forming a deformation section in the middle of the body.

[0017] When the body is subjected to external forces:

[0018] When the plastic body is too short, the body is subjected to external extrusion force, and several deformation segments are compressed, thus shortening the overall length of the body and obtaining a lower plastic body that meets the length dimensions.

[0019] When the plastic body is too long, it is subjected to tensile force. Several deformable segments are stretched, and the length of the body increases accordingly, thus obtaining a plastic body that meets the required length dimensions.

[0020] Obviously, whether the lower plastic piece is too long or too short, its length can be corrected under the action of external force, so its applicability is relatively high.

[0021] Meanwhile, the deformation segments located on both sides of the main body are symmetrically arranged, which not only improves the structural compactness, but also prevents the two ends of the main body from being misaligned under the action of external forces. Attached Figure Description

[0027] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0028] like Figure 1-3 As shown, the new type of plastic includes a long sheet-shaped body 1. The body 1 has a plurality of through deformation holes 11 in the middle along its width direction. A deformation segment 12 with a non-linear structure is formed between two adjacent deformation holes 11. The plurality of deformation segments 12 form a deformation part in the middle of the body 1 that can deform under the action of external force.

[0029] After the plastic is prepared and molded, the length of its body 1 may deviate from the preset size, specifically, the length of the body 1 may be too long or too short.

[0030] When the aforementioned body 1, which does not conform to the preset size, is installed on the battery cover, it will cause difficulties in installing the body 1, and the body 1, which does not conform to the preset size, may be damaged during the forced installation process.

[0031] This novel plastic material innovatively incorporates a deformation section in the middle of the body 1.

[0032] Since the deformable part has a porous, hollow structure and the deformable segment 12 is non-linear, it can achieve stable deformation when subjected to external force, thereby changing the length of the body 1. In other words, after the deformable part undergoes corresponding deformation, the body 1 can return to the preset length.

[0033] During the process of installing the main body 1 onto the battery cover, since the length of the main body 1 has reached the preset standard, the main body 1 can be installed into the battery cover conveniently and smoothly.

[0034] The main body 1 has a grid-like pressure relief section 2 in the middle, and the aforementioned deformable section is adjacent to the pressure relief section 2.

[0035] Both the pressure relief section 2 and the deformation section are grid-like perforated structures, and their centralized arrangement can effectively ensure the strength at both ends of the main body 1.

[0036] The deformation segment 12 is V-shaped. With the middle of the width direction of the body 1 as the reference, the left and right sides of the width direction of the body 1 are deformation region one and deformation region two, respectively. The opening direction of the deformation segment 12 in deformation region one is opposite to that in deformation region two.

[0037] When the main body 1 is subjected to an external compressive force, the deformation segment 12 is compressed. After the deformation segment 12 is compressed, its V-shaped inner angle becomes smaller, the width of the entire deformation segment 12 becomes smaller, and finally the length of the main body 1 becomes smaller, so that the main body 1 reaches the preset length.

[0038] When the main body 1 is subjected to a tensile force, the deformation segment 12 is stretched. After the deformation segment 12 is stretched, its V-shaped inner angle becomes larger, the width of the entire deformation segment 12 becomes larger, and finally the length of the main body 1 becomes longer, so that the main body 1 reaches the preset length.

[0039] The deformation section 12 is V-shaped, and its width can change steadily under compression and tension.

[0040] The opening of the deformable segment 12 faces the outer edge of the adjacent body 1.

[0041] This structure allows the deformation segments 12 in deformation region one and deformation region two to be symmetrically arranged. The symmetrical arrangement not only improves the overall structural compactness, but also prevents the two ends of the main body 1 from being misaligned during the stress process of the deformation part 12.

[0042] The width of the deformable segment 12 matches the thickness of the body 1.

[0043] This structure ensures that the deformation segment 12 can stably deform during the compression or stretching process of the main body 1.

[0044] The V-shaped angle of the deformed segment 12 has a rounded corner with a smooth transition.

[0045] This structure allows the deformation area to be concentrated at the smooth transition fillet with a longer length dimension, thus appropriately increasing its strength.

[0046] The deformable segment 12 has a reinforcing part 3 between its outer end and the body 1.

[0047] The main deformation area of ​​the deformation section 12 is at its V-shaped angle, and the reinforcement part 3 effectively improves the strength of the end connection of the deformation section 12.

[0048] The reinforcing part 3 is a transition part that smoothly transitions between the outer end of the deformable section 12 and the body 1.

[0049] The connection between the end of the deformable segment 12 and the body 1 is narrow. The reinforcement part 3 effectively increases the area of ​​the connection, thus ensuring the strength of the connection.

[0050] In other words, the V-shaped angle of the deformed segment 12 during the deformation process is the main deformation area, while the connection between the deformed segment 12 and the body 1 is the secondary deformation area.

[0051] The connection between the outer end of the reinforcing part 3 and the deformation section 12 and the body 1 is a rounded transition.

[0052] Depending on the specific circumstances, using a chamfered transition is also feasible.

[0053] The main body 1, the pressure relief section 2, and the deformation section 12 are all integral structures.

[0054] The unibody structure of the plastic material allows the entire lower plastic component to be rapidly molded using injection molding. Of course, injection molding is a current technology, and the injection molding process and molds will not be described in detail in this embodiment.

[0055] After the lower plastic body of this novel invention is manufactured, its length may not conform to the preset standard size; that is, the length of the body may be too long or too short. However, this novel lower plastic body innovatively incorporates a deformation section composed of several deformation segments in the middle of the body.

[0056] When the body is subjected to external forces:

[0057] If the length of the lower plastic is too short, the body will be subjected to external extrusion force, and some deformation sections will be compressed, thus shortening the overall length of the body and obtaining a lower plastic that meets the length requirements.

[0058] If the length of the lower plastic is too long, the body will be subjected to tensile external force, and some deformation segments will be stretched, thus increasing the length of the body, thereby obtaining a lower plastic that meets the length dimension standard.

[0059] Obviously, regardless of whether the initial state of the lower plastic is too long or too short, its length can be corrected under the action of external force, thus making it highly applicable. Of course, the range of being too long or too short here is relatively small. In this embodiment, it is for the lower plastic with a length deviation of 0.2-3 cm. If the deviation exceeds this size, it is not applicable.

[0060] Meanwhile, the deformation segments on both sides of the main body are symmetrically arranged, which not only improves the compactness of the structure, but also prevents the two ends of the main body from being misaligned under the action of external forces.

[0061] The above-described technical solution of this utility model addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies. The parts not covered in this application's technical solution are the same as or can be implemented using existing technologies, and will not be described in detail here.

[0062] The technical solutions in the above embodiments have clearly and completely described the content of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
