[0001] A PROTECTIVE BRACKET

[0002] Technical Field

[0003] The present invention relates to a protective bracket which aims to prevent the pieces composing the vehicle from injuring passengers and damaging other pieces composing the vehicle during a frontal crash in vehicles, by reducing them.

[0004] Background of the Invention

[0005] Electric vehicles consist of pieces such as passenger cabin, battery module, front and rear suspension systems, each with different functions. Bumper, radiator, crash bar and suspension system pieces included in the vehicle are damaged and these pieces increase the damage by damaging other pieces of the vehicle, in the event that a vehicle is involved in a frontal accident or crash. Suspension system pieces receive the impact of crash at the time of an accident occurring in the front part and transmit the said impact from the vehicle body to the passenger cabin and the battery modules. Therefore, due to the fact that the crash impact occurring in frontal accidents cannot be absorbed entirely, it damages components of the vehicle such as battery and passenger cabin and increases the damage ratio. As a result, today there is a need for solutions which will be used for reducing the impact of impact of crashes occurring in the front part of the vehicle particularly on the passenger cabin and batteries.

[0006] The Chinese patent document no. CN105365543A, an application included in the state of the art, discloses a structure which is used in the rear suspension system of electric vehicles and improves crash safety. The said structure consists of two longitudinal supporting arms and a beam connecting them. The front ends of the two longitudinal supporting arms are connected with a wheel bracket; whereas the back ends of them are connected with the vehicle body by means of a bushing support. The beam is located behind the wheel axis. Also, the rear suspension is located in front of the beam and a battery box is located at the vehicle bottom. In the event of a rear-end crash, the high-strength beam of suspension can protect the battery at a very good level, because the beam has high rigidity and endurance; in addition, in the event of a rear-end crash, the wheel can be pushed forwards by means of high-strength longitudinal supporting arms. Thereby, the wheels are prevented from entering the vehicle body and the lower part of the vehicle from shrinking. On the other hand, it is ensured to protect the battery by reducing the impact deformation.

[0007] Summary of the Invention

[0008] An objective of the present invention is to realize a protective bracket which enables to prevent the pieces composing the vehicle from injuring passengers and damaging other pieces composing the vehicle during a frontal crash in vehicles, by absorbing the load received on the traverse and to change the path of the load.

[0009] An objective of the present invention is to realize a protective bracket which prevents the battery from burning out by being damaged, the passenger cabin from being damaged and the passengers from being injured in the event that a vehicle is subjected to a frontal crash, by being used in electric vehicles.

[0010] Detailed Description of the Invention

[0011] “A Protective Bracket” realized to fulfil the objectives of the present invention is shown in the figures attached, in which:

[0012] Figure l is a perspective view of the inventive protective bracket.

[0013] Figure 2 is a perspective view of the inventive protective bracket on a vehicle. The components illustrated in the figures are individually numbered, where the numbers refer to the following:

[0014] 1. Protective bracket

[0015] 2. Plate

[0016] 3. Connection hole

[0017] 4. Bushing

[0018] T: Traverse

[0019] G: Body

[0020] B: Connecting member

[0021] The inventive protective bracket (1) for absorbing the load in order to prevent the load, which is subjected by the vehicle in case of frontal crashes, from passing from the traverse to the vehicle body comprises: at least one plate (2) which is connected to the traverse (T) from its one end and to the vehicle body (G) from its other end, and aims to receive the load incoming from the traverse (T) during crash; a plurality of connection holes (3) which are located on the plate (2), where connection members (B) pass through in connections of the plate to the traverse (T) and the body (G), and are located in the sections of the plate (2) where it receives the traverse (T) and the body (G); and at least one bushing (4) which is located on each of the connection holes (3) of the plate (2) in the connection part of the body (G), and aims to absorb the load together with the plate (2) during a frontal crash.

[0022] The plate (2) included in the inventive protective bracket (1) prevents particularly the battery and the passenger cabin -which are located on the vehicle body (G)- from being damaged in case of frontal crashes, by being positioned between the traverse (T) and the electric vehicle body (G). Therefore, the plate (2) is connected to the traverse (T) from its one end and to a position close to the body (G) part where the batter is located, from its other end. In preferred embodiments, the plate

[0023] (2) has a flat form. With its flat form, there is no possibility of folding and damaging other components during a crash.

[0024] In one preferred embodiment of the invention, the plate (2) has a flat form and is made of a three mm-thick S355 material by means of cataphoresis coating. Its weight is approximately 0.8 kg.

[0025] In one preferred embodiment of the invention, the connection holes (3) are the apertures where connecting bolt pass through and which are used for connection to the traverse (T) and the body (G). The plate (2) comprises the connection holes

[0026] (3) located between the said connection holes (3), other than the connection holes (3) located on the connection parts of the traverse (T) and the body (G). The said connection holes (3) provide convenience for connection purposes based on the sizes of the vehicle body (G) and the traverse (T).

[0027] In the said protective bracket (1), the bushings (4) are located on the plate (2) so as to receive the connection holes (3) on the body (G). The bushings (4) absorb the load received on the plate (2) in case of a frontal crash and ensures that the load received from the traverse (T) is transmitted to the vehicle body (G) by being reduced or it is not transmitted at all. The plate (2) and the bushings (4) transfer the reduces impact load to the vehicle body (G) homogeneously. Thereby, particularly in electric vehicles, batteries located just behind the plate (2) are not damaged and a possible fire risk is avoided.

[0028] In one preferred embodiment of the invention, the bushing (4) has a hollow cylinder shape and it is 14mm long. In addition, it is made of a 17MnB3 material and connected to the plate (2) by welding. Two inventive protective brackets (1) are included in vehicles and it enables to absorb the load without damaging the other pieces due to the fact that no folding incident occurs by means of their flat form. The bushings (4), which are used in the protective bracket (1) for safety purposes, ensures that the load -being subjected by the plate (2) during a frontal crash- is absorbed by emitting it on the vehicle body (G) homogeneously. Due to the homogeneous distribution of the load on the protective bracket (1), both the battery and the passenger vehicle are prevented from being damaged in electric vehicles and also the existing components overcome the crash with minimal damage.

[0029] Within these basic concepts; it is possible to develop various embodiments of the inventive “Protective Bracket (1)”; the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
