AI Technical Summary
Electric vehicle battery modules located under the vehicle body are vulnerable to external impacts, leading to potential damage, non-reusability, and fire risks, with existing solutions failing to provide adequate protection.
A protective cover comprising a plate with lugs and apertures, made of S550 sheet material, is designed to cover the gap between the vehicle body and traverse, absorbing impacts and preventing damage to the battery module by bouncing them off, while being lightweight and securely mounted using connection holes.
The solution effectively protects the battery module from impacts, maintaining its functionality and preventing damage, while allowing the vehicle to navigate obstacles without compromising the battery's integrity.

[0001] DESCRIPTION
[0002] A BATTERY PROTECTIVE COVER
[0003] Technical Field
[0004] The present invention relates to a protective cover for protecting the battery module, which is located under the body of electric vehicles and consists of combining a plurality of batter cells, against external impacts.
[0005] Background of the Invention
[0006] Battery modules, which provide the energy to be used for moving electric vehicles, are included on the surfaces of the electric vehicle body facing the ground. The battery modules are obtained by combining a plurality of battery cells and they are fixed to a fixture together with the front and rear axle modules on the front. Since a battery module is located in one of the areas, which are closest to the ground, under the vehicle body; it may be exposed to impacts in cases such as passing over a bump during drive.
[0007] Today, there is no protection solution in order to protect a battery module located on the lower part of electric vehicles. In the event that a vehicle hits an obstacle at a certain height, the batteries may be damaged. Since this causes the batteries to become non-reusable, it leas to high costs for vehicle owners. On the other hand, in the event that the battery module receives an impact, a fire may occur in the vehicle. Therefore, today there is a need for solutions which will protect the battery module from external impacts.
[0008] The Chinese Utility Model document no. CN213323390, an application included in the state of the art, discloses a lower guard plate used under electric vehicles, the said lower guard plate reduces the wind resistance coefficient of an electric automobile and it consists of a front cabin lower guard plate, a battery pack lower guide plate and rear cabin lower guard plate in order to completely cover the underside of the vehicle. Except the said lower guard pieces, the said Chinese Utility Model document discloses right side and left side guard plates which are located on the right and left of the vehicle and present at the sides of the battery pack lower guard plate. The inventive front cabin lower guard plate consists of two pieces, namely a front cabin lower guard plate and a rear cabin lower guard plate. The front cabin lower guard plate and the rear cabin lower guard plate are interconnected in the lower and rear position of the front axle. The said pieces are interconnected by means of bolts in a superimposed way and thus, connection of the said pieces is ensured in a firm and air-tight way.
[0009] The European patent document no. EP2805877A1, another application included in the state of the art, discloses an undercover used for preventing an obstruction or a stone from hitting on a battery unit -which is included in a vehicle-during driving. The said undercover is used in a vehicle including a battery unit and an electric motor, has an electromagnetic shield effect and smoothens a flow of air under the vehicle. The undercover comprises an undercover body and a shield member formed of a conductive fabric. The undercover included in the said EP document comprises a plurality of holes and the undercover is connected to the vehicle body from under the vehicle by means of bolts passed through the said holes. The undercover is connected to the vehicle body over the side members and the traverse located on the front side of the vehicle.
[0010] Summary of the Invention
[0011] An objective of the present invention is to realize a protective cover for preventing damages, which may occur from the traverse located at the front of the vehicle towards the vehicle body during the movement of the vehicle, from contacting the battery module by closing the part between the traverse and the section where the battery module of the vehicle body are located. for protecting the battery module, which is located under the body of electric vehicles and consists of combining a plurality of batter cells, against external impacts.
[0012] Detailed Description of the Invention
[0013] “A Battery Protective Cover” realized to fulfil the objective of the present invention is shown in the figures attached, in which:
[0014] Figure l is a top view of the inventive battery protective cover.
[0015] Figure 2 is a top view of the internal volume of the inventive battery protective cover on a vehicle.
[0016] The components illustrated in the figures are individually numbered, where the numbers refer to the following:
[0017] 1. Cover
[0018] 2. Plate
[0019] 3. Lug
[0020] 4. Connection hole
[0021] 5. Aperture
[0022] T: Traverse
[0023] A: Vehicle body
[0024] B: Battery module
[0025] The inventive cover (1) for protecting the battery modules, which are located on the lower surface of the vehicle body, against impacts comprises: at least one plate (2) which has a form so as to cover the aperture located between the traverse (T) and the vehicle body (A) of the vehicle; a plurality of lugs (3) which are located at the edges of the plate (2) at certain intervals, used for the traverse (T) and the vehicle body (A) connections of the plate (2), and comprise at least one connection hole (4) where the connection member can pass through in thereof; and a plurality of apertures (4) which are located at the edges of the plate (2) so as to be between the lugs (3).
[0026] The plate (2) included in the inventive protective cover (1) has a flat form at the part where it is connected to the vehicle body (A) and an angled form at the part where it is connected to the traverse (T). The angled form of the plate (2) towards the traverse (T) enables to bounce the impacts and thus prevents the battery module (B) from being damaged.
[0027] In one preferred embodiment of the invention, the lugs (3) are located at the edges of the plate (2) in the same direction with the vehicle width. On the lugs (3), there are connection holes (4) for providing the mounting of the plate (2) to the traverse (T) and the vehicle body (A), upon the connection members are passed through in thereof. The said lugs (3) and the connection holes (4) are located on the plate (2) so as to correspond to the connection slots where they will be connected on the vehicle. The connection holes (4) are located on both the lugs (3) and at the edges of the plate (2).
[0028] In one preferred embodiment of the invention, the plate (2) is a single piece and it is made of S550 sheet material. The plate (2) and the lugs (3) are produced by being formed via press. The plate (2) and the lugs (3) are preferably 2.5 mm thick. The assembly of plate (2) and lug (3) weighs 6.5 kg.
[0029] The apertures (5) -which are located between the lugs (3) in the inventive cover (1) - enable to facilitate the mounting of the plate (2) to the vehicle body (A) and the traverse (T), also to reduce the weight of the plate (2) and to intervene the under part of the vehicle from outside. The inventive battery protective cover (1) receives the impacts that may occur on the battery module (B) and also enables the vehicle to jump over the obstacle - which creates the impact- by bouncing, upon it closes the aperture between the traverse (T) and the vehicle body (A) where the battery module (B) are located on the lower surface of the vehicle body (A). Thus, it is possible to maintain the functionality of batteries by preventing the battery module (B) which is located on the lower part of the vehicle, from being damaged. Within these basic concepts; it is possible to develop various embodiments of the inventive “Battery Protective Cover (1)”; the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
