TECHNICAL FIELD
[0001] The present disclosure described herein, in general, relates to the provision for mounting of two components of gaseous/liquid cylinder holder, thereby further referred to as vehicle cylinder holder. In particular, the present disclosure relates to an effective joinery structure for connecting a holder component and a leg component of a vehicle cylinder holder.
BACKGROUND
[0002] The background description includes information that may be useful in understanding the present disclosure. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed subject matter, or that any publication specifically or implicitly referenced is prior art.
[0003] Alternate fuels, like Compressed Natural Gas (CNG), Liquefied petroleum gas (LPG), etc., run vehicles are becoming relatively popular in the market due to clean energy, low pollution and low cost of use. Such CNG/LPG vehicles, unlike petrol or diesel vehicles, require a CNG/LPG cylinder or gaseous/liquid cylinder, thereby further referred as vehicle cylinder holder, to be mounted at the rear side, i.e., in boot space area of the vehicle. In order to achieve a firm installation and mounting stability of the cylinder, a vehicle cylinder holder or structure typically consists of a pipe structure bent in such a way to hold the gas cylinder is usually installed on the floor in the boot space area of the vehicle. The vehicle cylinder holder prevents the gas cylinder from falling off due to body twisting, braking, bumping and collision of the vehicle. At the same time, the vehicle cylinder holder facilitates the loading and unloading of the cylinder and removal and placement of the spare tire.

[0004] Designing of such a vehicle cylinder holder for spacious car is easy but designing of a holder for a small or compact vehicle poses several challenges. Various challenges posed are design constraints involving BIW structure, challenge related to ease of spare tire accessibility, along with various assembly requirements. One solution to this problem is to use a single component vehicle cylinder holder for compact vehicle. However, the single component vehicle cylinder holder can be made possible for cylinder layout at low height from vehicle rear floor, as the vehicle cylinder holder along with the cylinder is to be fitted inside the vehicle from either the rear door or from back door of the vehicle. In both cases, the entry height has some limitation based on vehicle dimensions, thereby constraining the assembly ease and hence limiting the overall layout height of cylinder. Due to the low height of the vehicle cylinder holder, spare tire removal may become a problem for which a vertical layout of a spare tire is created or the tire is kept below the rear floor of the vehicle which increases the cost and weight of the vehicle. This further leads to customer dissatisfaction as there has been compromise on either ease of spare tire usage or with the available boot space for luggage loading. Due to this, the single component vehicle cylinder holder is generally preferred on case to case basis especially for specific market segment vehicles, not for all segments. Instead, a two-component vehicle cylinder holder is more used. The two-component vehicle cylinder holder comprise a holder component and a leg component. Each component, i.e., the holder component and the leg component consists of multiple child parts joined together by welding or other fastening means. In a known two-component vehicle cylinder holder, the two components are divided in height in such a way that the vertical pipe component has to be split to make it feasible to be able to enter via either rear door or back door of a vehicle. Being the requirement of splitting the cylinder frame in between the vertical pipe, there have been many concerns. Assembling or joining of these components in the assembly shop is not easy due to adjustment issues. Further, the joint could be the weak link that could crack or fail during the running condition of the vehicle.

[0005] In view of the above, there is a need to have an easy and effective joinery structure of the two components of vehicle cylinder holder that provides guide and location control in assembly direction as well as provide sufficient joinery strength thereby giving an improvement in overall structure performance. Further, the load transfer from the vehicle cylinder holder to the floor of the vehicle should take place without the joint becoming the weakest link and cracking or failing during the load transfer or running condition of the vehicle. Therefore, there is a need in the art to provide an easy and effective joinery structure for connecting a holder component and a leg component of a vehicle cylinder holder that is simple and inexpensive, and which can be placed in the existing vehicle to eliminate the existing above mentioned problems.

[0030] FIG. 1 illustrates structure of an existing one component and two-component gaseous/liquid cylinder holder, thereby further referred to as vehicle cylinder holder 100. The two-component vehicle cylinder holder 100 comprises top framework also known as the holder component 102 and a bottom framework also known as the leg component 104. Each component, i.e., the holder component 102 and the leg component 104 consists of multiple child parts joined together by welding or other fastening means. In a known two-component vehicle cylinder holder, the two sets or components are usually divided in height in such a way that the vertical pipe component has to be split to make it feasible to be able to enter via either rear door or back door of a vehicle. As the vehicle cylinder holder along with the cylinder is to be fitted inside the vehicle from either the rear door or from back door of the vehicle, there has been limitation on the entry height from either rear door or back door based on vehicle dimensions, thereby constraining the assembly ease and hence limiting the overall layout height of cylinder. Due to the low height of the vehicle cylinder holder, spare tire removal may become a problem for which a vertical layout of the spare tire is created or the tire is kept below the rear floor of the vehicle which increases the cost and weight of the vehicle. This further leads to customer dissatisfaction as there has been compromise on either ease of spare tire usage or with the available boot space for luggage loading.
[0031] In this case, the two components are divided in height in such a way that the vertical pipe component has to be split to make it feasible to be able to enter via either the rear door or back door of a vehicle. Being the requirement of splitting the cylinder frame in between the vertical pipe, there have been many concerns. Assembling or joining of these components in the assembly shop is not easy due to adjustment issues. Further, the joint could be the weak link that could crack or fail during the running condition of the vehicle.
[0032] In view of the above, there is a need to have an easy and effective joinery structure of the two components of the vehicle cylinder holder that provides guide and location control in assembly direction as well as provide

sufficient joinery strength thereby giving an improvement in overall structure performance. Further, the load transfer from the vehicle cylinder holder to the floor of the vehicle should take place without the joint becoming the weakest link and cracking or failing during the load transfer or running condition of the vehicle. Therefore, there is a need in the art to provide an easy and effective joinery structure for connecting a holder component and a leg component of a vehicle cylinder holder that is simple and inexpensive, and which can be placed in the existing vehicle to eliminate the existing above mentioned problems.
[0033] Accordingly, FIGS. 2A-2E illustrates a joinery structure for connecting a holder component and a leg component of a gaseous/liquid cylinder holder, thereby further referred to as vehicle cylinder holder 200. FIG. 2A shows the exploded view of the two-component vehicle cylinder holder 200. The vehicle cylinder holder 200 comprises a holder component 202 and a leg component 204. The holder component 202 comprises cradle pipes 206 to be connected or mounted over vertical leg pipes 208 of the leg component 204.

The fasteners 218 can be screws, bolts and the like. The second fastener openings 214a and the third fastener openings 216a cannot be differentiated from the FIG. 2B as they overlap each other.
[0035] In an embodiment, the first bracket 212, a second bracket 214 and the third bracket 216 can be connected to each other by welding and riveting also. The first bracket 212 comprises a central portion 212b with side faces 212c. The central portion 212b is attached to the cradle pipe 206 of the holder component 202 and the side faces 212c have the first fastener openings to which the fastener nuts 212a are welded for receiving the fasteners 218. The side faces 212c extend perpendicularly beyond at least one end to form flanges 212d having locating holes 212e for facilitating easy and precise mounting during assembly of the joinery structure. The flanges 212d restricts the motion of the holder component 202 in the Z-direction as shown in FIG 2B.
[0036] The second bracket 214 comprises a central portion 214b with side faces 214c wherein the central portion 214b helps in locating and receiving the cradle pipe 206 and the side faces 214c are provided with second fastener openings 214a corresponding to the first fastener openings. The side faces 214c restricts the motion of the holder component 202 in the Y-direction as shown in FIG 2B. The central portion 214b and the side faces 214c extend perpendicular to the length of the second bracket 214 so as to form flanges (214d) having locating

dimples 214e that match with the locating holes 212e formed on the flanges 212d of the first bracket 212.
[0037] The third bracket 216 also comprises a central portion 216b which is attached to the horizontal leg pipe 210 of the leg component 204. The central portion 216b have perpendicular flanges 216c provided with the third fastener openings 216a for the fasteners 218 to pass through. The third fastener openings 216a are sandwiched between the side faces 212c of the first bracket 212 and the side faces 214c of the second bracket 214.
[0038] The central portions 212b, 214b, 216c of the first, second, and third brackets 212, 214, 216 are having a depth matching a radius of the cradle pipe 206, the vertical leg pipe 208, and horizontal leg pipe 210, respectively, and are attached to the cradle pipe 206, the vertical leg pipe 208, and horizontal leg pipe 210, respectively, by joining methods including gas metal arc welding or metal inert gas welding such as CO2 welding to provide a strong and rigid connection.
[0039] FIGS. 2C and 2D show the assembled condition of the two-component vehicle cylinder holder 200 in accordance with the present disclosure. The highlighted rectangular region A in FIG 2C. shows how the connection is established between the holder component 202 and the leg component 204 of the vehicle cylinder holder 200. The first bracket 212 the second bracket 214 and the third bracket 216 of the joinery structure are attached to the cradle pipe 206 and the vertical and horizontal leg pipes 208, 210 respectively. The three bracket joint formed by connecting the first bracket 212 with the second bracket 214, the third bracket 216 being sandwiched in between help in secure and rigid connection or mounting of the holder component 202 on the leg component 204 which ensures sufficient load transfer from cylinder to the floor joinery without becoming the weak link itself.
[0040] In FIG. 2D, although not visible but when the fasteners 218 are fastened in the fastener openings 214a, 216a of the first, second and third brackets 212, 214, 216, a clearance gap is maintained between the cradle pipe 206 and the vertical leg pipe 208 so as to remove the niggling sound produced due to touching

of the cradle pipe 206 and the vertical leg pipe 208 in vehicle movement as non-movable connection (welding, etc.) is not possible between the above two pipes 206 and 208. The locating dimples 214e, locating holes 212e, height resting faces/flanges and the central portion 214b helps in easy assembly of holder component 202 with leg component 204 in assembly shop.
[0041] The brackets 212, 214 and 216 are made up of strong and stiff metal or alloy materials like stainless steel, cast iron, carbon steel, tool steel and the like. This ensures that the overall structure doesn't crack or fail during the vehicle running condition or load transfer. The joinery structure comprising of brackets has various features which further helps in providing ease of locating, positioning as along with the sufficient strength.
[0042] FIG. 2E show the closer or magnified back view of the joinery structure in accordance with the present invention disclosure. The joinery structure is quite symmetrical at both the right-hand side and left-hand side and also each part is symmetric about its own mid axis, as shown in the FIG.2E which thereby makes the use of same part on both sides possible and thus helps in saving the die cost of the brackets 212, 214 and 216. Sections A-A, B-B and C-C of the back view of the joinery structure are illustrated in the FIG. 2E.
[0043] In an aspect, the cross-section of the cradle pipes 206 the vertical leg pipes 208 and the horizontal leg pipes 210 is circular and the cross-section of the central portion 212b, 216b corresponds to this circular shape of the pipes whereas the central portion 214b of second bracket 214 is rectangular in shape to receive the cradle pipe 206 along with first bracket 212 with ease. However, this should not limit the scope of the invention and in general, the cross-section of the central portions of the first bracket 212 and the third bracket 216 corresponds to the cross-section of the cradle pipe 206 and the horizontal leg pipes 210 in such a way that the joinery structure is assembled considering all tolerances. The cross-section of the cradle pipes 206, the vertical leg pipes 208 and the horizontal leg pipes 210 can be square, rectangular, and the like and accordingly the cross-section of the central receiving portion 212b, 214b, 216b may vary.
