Description

A Shock Absorber Frame Profile for Battery Carriers
Technical Field
The invention relates to a frame profile characterized by improved shock absorbing for use in battery carriers protecting/carrying battery package of electrical vehicles.
Background of the Invention
Today electrical vehicles are becoming popular and vehicles having battery carriers are highly used. Battery boxes are placed in four different ways in electrical vehicles.
• On vehicle floor in T shape
• As integrated to floor
• Spread in rear part of vehicle
• Platform (skateboard)
In modern and top segment vehicles, battery carrier of platform type in rectangular form is used. With battery carrier of platform type, the batteries located in the battery box are distributed into vehicle and thus a better balance of weight centre of vehicle is provided.
The batteries located in the battery carriers should not take any strokes. Otherwise, risky conditions for those in the vehicle may occur. In present boxes it is needed to absorb the side sections (sections parallel to the vehicle) before it causes stress by deformation and displacement via battery modules in case of hitting and any attempt to battery area should be prevented.
In the related art although stroke absorption providing embodiments are used in side frame, more improved and innovative solutions are needed in this matter.
When patent search is made in the related art, an application numbered CN202011141059 is discovered. In the application enforced beam structures are used with battery carrier wall profiles. The beam structures comprises aluminium profile side beam and twisted plates made from aluminium. Use of multiple members produced in different forms for absorption process causes disadvantages in terms of weight, workmanship, part cost and production time. As a result, due to above described disadvantages and inadequacy of existing solutions, it has been necessary to make development in the related art.
Purpose of the Invention
One purpose of the invention is to provide absorption of strokes coming to battery carrier side profile by absorption structure hereof before transmission to inner part of batteries.
Another purpose of the invention is to provide advantage in terms of production and workmanship as the structure providing absorption in side frame profile can be produced through extrusion form.
Another purpose of the invention is to provide absorption with one single part structure of frame profile without need for additional support parts. Thus saving is made from weight, workmanship and part cost.
In order to achieve above mentioned purposes, the invention relates to a frame profile having an external wall facing outside part where stroke comes onto, an inner wall facing the part where batteries will be placed in case of use and convenient for use in battery carriers protecting/carrying battery package of electrical vehicles. Invention is characterised by comprising;
- an absorption structure located between said inner wall and outer wall,
- said absorption structure comprising; o at least two support extensions connected to said outer wall from one end, o support extension connection part where said inner support extensions are connected from other ends, o side extensions providing connection of said support extension connection part and inner wall and thus providing formation of an absorption chamber.

Detailed Description of the Invention
In this detailed description, the preferred alternatives of the shock absorber frame profile (10) being subject of this invention have been disclosed solely for the purpose of better understanding of the subject and described in a manner not causing any restrictive effect.
Figure 1 shows a cross-section view of an alternative embodiment of frame profile (10) of the invention while figure 2 shows a side perspective view. According to it, said frame profile (10) comprising one inner wall (11) facing the part where batteries will be placed in case of use and an outer wall (12) facing outside part where stroke will come. Frame profile (10) comprises upper side (14) and lower side (15) connected to said inner wall (11) and outer wall (12).
An absorption structure (13) is placed between said inner wall (11) and outer wall (12). Said absorption structure (13) comprises;
- at least two inner support extensions (131) connected to outer wall (12) located in the direction from which the stroke comes, and formed preferably substantially parallel to one another,
- support extension connection part (132) where said inner support extensions (131) are connected from other ends, side extensions (133) providing connection of said support extension connection part (132) and inner wall (11). Said support extension connection part (132) is preferably in spring form. Said spring inner surface is the part where inner support extensions (131) are connected. Support extension connection part (132) is preferably located mostly at the midpoint between inner wall (11) and outer wall (12). Preferably there are two separate support extension connection parts (132), connecting each inner support extension (131) and a support extension part (132) (see Figure 3). Said side extensions (133) is connected to support extension connection part (132) from both ends. Thus absorption chamber (134) is formed. Said side extensions (133) are preferably made angular to enlarge absorption chamber (13) towards inner wall (11). Face of side extensions (133) facing outside of absorption chamber (134) and inner wall (11) pas an angle ranging from 90 to 100 degrees. The angle supports deflection of upper edge (14) and lower edge (15) inwardly during stroke.
Inner support extensions (131) are substantially parallel to frame profile (10) upper edge (14) and lower edge (15). At least one recess (16) formed towards profile inner area is provided on said upper edge (14) and lower edge (15). Said recesses (16) are aligned facing each other.
Said absorption embodiment (13) is located preferably on midpoint of frame profile (10).
After stroke comes to battery carrier’s frame profile (10), components to meet the stroke after outer wall (12) are inner support extensions (131) of absorption structure (13). Said inner support extensions (131) transmits the stroke to support extension connection part (132) in spring form where connected. Said support extension connection part (132) absorbs the energy by flexing inside the absorption chamber (134). Meanwhile, side extensions (133) where said support extension connection part (132) is connected also flexes towards absorption chamber (134) and provides support. Thus reach of coming stroke to inner wall (11) is prevented.
Recesses (16) provided in a manner to face each other on frame profile (10) upper edge (14) and lower edge (15) facilitate flexing of upper edge (14) and lower edge (15) toward frame profile inner area and provide energy absorption in the desired direction.
