[0005] PRIOR ART

[0006] With the widespread use of electric and hybrid vehicles, housing structures especially for accommodating batteries are developed specifically for the vehicle design. However, when capacity preference and compatibility with the vehicle chassis are taken into consideration, separate design and separate production is required for each vehicle and option. Especially with the widespread use of options such as vehicle modifications (retrofits), there is a need for common battery designs.

[0007] With the development of energy storage batteries, the trend of battery technology has been to increase the utilization rate of battery active materials, increase the specific energy of batteries, and achieve light weight and modularity. Battery housings in the known art are fixed to the vehicle and their portability is limited. There is a requirement to produce specific housings for each vehicle and recycling / reuse thereof is limited.

[0008] The SIPO document with publication number CN21029654411 describes a modular battery box structure. In this application, the layered structure consists of a housing structure that can be placed on top of each other and optimized in height. Parameters such as length can be determined and are particularly limited to predetermined dimensions. For this reason, said application does not meet the needs sufficiently.

[0009] As a result, all the above-mentioned problems have made it imperative to make an innovation in the relevant field. OBJECT OF THE INVENTION

[0044] DETAILED DESCRIPTION OF THE INVENTION

[0045] In this detailed description, a modular battery case (C) subject to the invention is explained by way of example only for a better understanding of the subject, which shall not create any limiting effect.

[0046] The subject of the invention relates to a battery case (C) structure that can be easily and quickly adapted for vehicles with different designs, especially suitable for use in electric and hybrid vehicles.

[0047] Fig. 1 shows a representative drawing showing the battery case (C). The case (C) is adjustable in size and consists of interconnected carrier elements (20) and body panels (10) associated with said carrier elements (20). The body panel (10) can form side walls, bottom walls and top walls. The carrier elements (20) support said body panels (10).

[0048] The invention is a battery case (C) that can be easily and quickly adapted for vehicles with different designs, suitable for use in electric and hybrid vehicles, characterized in that it comprises a plurality of interconnected carrier elements (20) supporting at least five surfaces, a plurality of body panels (10) connected to the skeleton structure formed from said carrier elements (20), so as to ensure that at least two carrier elements (20) are interconnected and located in different positions relative to each other: a sliding recess (22) and a sliding protrusion (24) corresponding to each other on and below each carrier element (20) and allowing the two carrier elements (20) to slide on each other; a linear channel (27) extending longitudinally on the carrier element (20) and allowing said linear movement to take place; a connecting body (21 ) at one end of each carrier element (20), at least one pin opening (210) on said connecting body (21 ) for associating two carrier elements (20); a locking pin (30) having a pin body (32) passing through said pin opening (210) and linear channel (27) for interconnecting two consecutive carrier elements (20). Fig. 2 shows the two interconnected carrier elements (20) of the invention, and fig. 3 and fig. 4 show the carrier element (20) in perspective. Each carrier element (20) is in the form of a linear profile and has a connection body (21 ) at one end, and a second carrier element (20) can be connected by means of at least one locking pin (30) through the pin opening (210) of said connection body (21 ). Each carrier element (20) comprises a sliding recess (22) on one surface and a sliding protrusion (24) on the other surface, and said sliding recess (22) and sliding protrusion (24) correspond to each other. In this way, the two carrier elements (20) can slide linearly on top of each other.

[0049] Fig. 6A and fig. 6B show the drawing showing the interconnection of the two carrier elements (20). Each carrier element (20) comprises a linear channel (27) extending along the profile. The connecting body (21 ) of the carrier element (20) comprises a pin opening (210) in the form of a slot. Through said pin opening (210), the pin body (32) of the locking pin (30) enables a second carrier element (20) to be connected through the linear channel (27). With the axis of the pin body (32) resting on the connecting body (21 ) of a carrier element (20), a second carrier element (20) is linearly movable and at the same time angularly rotatable on the linear channel (27) extending along the profile of the carrier element (20). Said movement structure is shown in fig. 7A and fig. 7B.

[0050] While one of the carrier elements (20) is stationary, the other carrier element (20) can move linearly by sliding on the sliding recess (22) and the sliding protrusion (24). In this way, length adjustment can be achieved. Similarly, the second carrier element (20) can rotate angularly and position itself in a 90° or 180° position. During positioning in the 180° position, the position is maintained stable by means of the fixing recess (23) of the consecutive carrier elements (20) and the protrusion that fits into said fixing recess (23).

[0051] The position of the movable carrier element (20) is controlled by means of the locking pin (30). The locking pin (30) comprises a cap (31 ) at both ends and a cap support surface (310) in the region following each cap (31 ). The cap support surface (310) provides bearings to the locking pin (30) on the carrier element (20). Between the pin body (32) and the cap (31 ), it comprises springs (33) for both caps (31 ) located preferably at either end of the pin body (32). The pin body (32) and the caps (31 ) are connected to the spring (33). The spring (33) preferably has a Z-shape and is particularly made of thin plate, and has a recessed form (zig-zag). In line with the force exerted by said spring (33) form on the outer and movable carrier element (20), at least one rivet (28) in the related region slides so that the position of the movable carrier element (20) remains constant. In the event that the force applied to the caps (31 ) disappears, the rivet (28) returns to its original position and applies force to the carrier element (20) so that its position remains constant.

[0052] In the preferred embodiment of the invention, the support surface (26) is located on the connecting body (21 ). By means of said support surface (26), when the two carrier elements (20) are positioned on top of each other, angular support is provided.

[0053] In the preferred embodiment of the invention, there is an opening (200) form on the carrier element (20). Said opening (200) facilitates heat transfer through the carrier element (20) and reduces the weight of the carrier element (200).

[0054] The scope of protection of the invention is specified in the appended claims and cannot be limited to what is described for illustrative purposes in this detailed description. It is clear that a person skilled in the art can produce similar embodiments in the light of what is explained above and the technical drawings, without deviating from the main theme of the invention.
