Description

1 TARIFF BATTERY CARRIER FITTING SYSTEM Technical Area The invention relates to a snap-in system used in battery carriers for electric vehicles. State of the Art 5 Today, battery carriers typically deliver battery packs to electric vehicles (EVs). These are load-bearing structures that are placed under the vehicle or in the trunk. The carriers ensure that the batteries are safely placed inside the vehicle, while at the same time They also make the electrical connections for the batteries. In current technology, battery carriers are generally mounted on the vehicle's chassis or substructure. They are secured. These carriers use special fasteners to hold the battery modules in place. points or fasteners (screws, latches, connectors, etc.) It is securely fastened using... In the known state of the art, battery carriers are mounted on the side profiles. They are fixed to the vehicle at certain points. The central crossmembers carrying the modules are attached to the side profiles at 15°. Internally, they are joined using welding / riveting / mechanical connection methods. From the side... During the upcoming impact, the force will come directly to the side profile, and the side profile will be plastic. It undergoes deformation. The deformed side profile pushes the battery carrier inwards. The movement progresses through the modules depending on the amount of impact during the process, and this This is an undesirable situation. 20 Center crossmembers (horizontal structural elements of the vehicle chassis / beams / crossmembers) and side profiles In the case of direct welding, the planarity of the side profiles and the length of the central beams Considering the dimensional tolerances, the middle beams are suitable for mass production. In order to ensure proper assembly, negative length tolerances must be given. Consequently... If tolerance accumulation occurs, the weld quality is seriously negatively affected. 25 is affected. If this problem is solved, some battery carriers will have additional features. using brackets, welding or mechanical joining methods It has been observed that this solution method increases process time and therefore cost. This necessitates the use of additional fasteners. 2 In conclusion, due to the negative aspects described above and the current solutions being the subject of discussion... Due to its shortcomings, an improvement is needed in the relevant technical field. It has been made. The purpose of the invention The invention was created by drawing inspiration from existing situations and addressing the aforementioned drawbacks. 5 It aims to solve the problem. The main purpose of the invention is to prevent damage to the side profiles from being damaged during an accident, while also protecting the central vertical profiles. A docking system that allows the transfer of battery carrier data to other profiles. It is to reveal. Another purpose of the invention is to ensure that the incoming damage does not only occur in the lateral profile in the direction of the damage. 10 The aim is to increase the impact resistance of the carrier. Another purpose of the invention is to produce B and L profiles of the middle and side profiles using the roll forming method. A system with high resistance to energy absorption thanks to its cross-section. to present. Another purpose of the invention is to connect the central vertical profiles to the vehicle by passing them through the side profiles. 15 Thanks to its extension to that point, the holes at the connection point are opened after assembly. by opening it up, both to solve the tolerance problem at this point and to adjust the vertical profile dimensions. Since there are no current limitations, wider size tolerances can be given. The aim is to provide a low-cost product. To fulfill the purposes described above, the invention consists of a cooling unit at the top. 20 The battery carrier, which has a plate and a cover underneath, is damaged in case of impact. It is a joint system that increases its strength, and its characteristic is;  Produced using the roll forming process, it absorbs energy and forms batteries. a robust side profile that ensures the protection of the modules inside and  Roll 25, mounted to the side profile without the need for any welding. By absorbing energy produced through the form process, it transfers energy within the battery. a robust central vertical profile that ensures the protection of the modules It includes. 3 The structural and characteristic features and all the advantages of the invention are given in the figures below. This becomes clearer thanks to the detailed explanation written with references to these figures. This will be understood as such, and therefore the evaluation will also take these forms and detailed explanations into account. This should be done taking that into consideration. 5 Figures That Will Help Understand the Discovery Figure 1 shows a view of the assembly of the interlocking system. Figure 2 shows a side view of the interlocking system. Figure 3 shows the assembly of the docking system with the cooling plate. Explanation of Part References 1. Side profile 10 2. Medium vertical profile 3. Zodiac Sign 4. Cover 5. Cooling plate Detailed Description of Find 15 This detailed description outlines the preferred configurations of the interlocking system that is the subject of this invention. This explanation is provided solely to facilitate a better understanding of the subject. The subject of the invention is a cooling plate (5) on top and a lid (4) on the bottom. a snap-fit ​​system that increases impact resistance in case of damage to the battery carrier In its basic form, it consists of a side profile (1), a central vertical profile (2) and bushings (3). 20 The mentioned side profile (1) was produced by the roll forming process and is an L-shaped, robust form. It is a part with high energy absorption. The central vertical profile (2) has no side profiles. It is assembled without a welding process. The mentioned middle vertical profile (2) roll form It is produced by the process and has a B-section form structure. Side profile (1) and middle vertical profile (2) The profiles mentioned are assembled together by means of a bushing (3). 4 Once the assembly is complete, the modules inside the battery carrier are protected from impacts and It provides protection by absorbing maximum energy in the event of potential damage. In the interlocking system that is the subject of the invention, the central vertical profiles (2) will carry the battery carriers. and therefore it must be rigid and strong, and the side profiles (1) on the contrary It must be a structure with damage absorption properties, therefore the damage is 5 During this process, damage to the side profiles was transmitted through the central vertical profiles to the battery carrier. This will ensure that the incoming damage is transferred to other profiles. Thus, only the damage received will be recorded. Since the side profile (1) in that direction will not meet the impact resistance of the carrier will be increased. The central vertical profiles (2) pass through the side profiles (1) and extend to the vehicle connection point 10 Because it is extended, the holes at the connection point are drilled after assembly, both at this point and The tolerance problem will be resolved, as well as the current limitations on vertical profile dimensions. Since this is not the case, wider size tolerances can be given. This will improve the product. It makes it cheaper.
