KR102653693B1 - The braket and side cover for an isolation board for fuel tank of lpg vehicle - Google Patents

Abstract

The present invention is a side wall bracket that supports the isolation board that isolates the LPG fuel cylinder from the top on both sides. Regarding the side cover.
Especially in the case of SUV vehicles where the cabin and trunk are not spatially isolated, it is necessary to completely isolate the LPG fuel cylinder from the cabin. Otherwise, a situation will be created where the vehicle will be driven with the fuel cylinder exposed to the vehicle's occupants. It is necessary to completely isolate the fuel cylinder physically through a newly designed isolation board, while also effectively blocking noise or vibration generated from the cylinder. In addition, load-bearing capacity must be improved to prevent various loads placed on the trunk carpet from being transferred to the fuel cylinder. For this you will need a pair of side wall brackets to support each side of the isolation board. You will also need side covers that fit into the storage compartment, which are installed on a pair of side wall brackets.

Description

Side wall bracket and side cover for fuel tank isolation board for LPG vehicle {THE BRAKET AND SIDE COVER FOR AN ISOLATION BOARD FOR FUEL TANK OF LPG VEHICLE}

The present invention relates to components installed in the trunk of a car, and particularly to technology related to a board installed in the trunk of an LPG vehicle.

It is known that vehicles using LPG as fuel are more friendly to preventing the spread of fine dust than vehicles using gasoline or diesel fuel. It is expected that more people will choose LPG vehicles, and that more vehicles will change fuel to LPG and install LPG fuel tanks in their vehicles. Fuel tanks cannot be installed inside the cabin where passengers are located for safety reasons. Therefore, LPG vehicles have an LPG fuel tank installed in the trunk.

Conventionally, LPG vehicles were sedan-type vehicles, and the cabin and trunk where the fuel tank was installed were structurally isolated. However, in types such as sports utility vehicles (SUVs), the cabin and trunk are not structurally isolated. If a fuel tank is installed in such a vehicle, how can the area where the fuel tank is located and the cabin be effectively isolated? Not only must safety be ensured, but ride comfort must be secured by reducing various NVH (Noise Vibration and Harshness) generated from the fuel tank, and at the same time, the fuel tank must be managed effectively.

In order to solve the above problems, the inventor of the present invention researched and developed the problem, and after repeated trial and error, he came to complete an isolation board that covers and isolates the fuel cylinder from above, and applied for it under Patent Application No. 10-2019-0066008. It has been done. However, in order to install this isolation board, a unique bracket design was required, and in addition, the use of a bracket that corresponded to the morphological structure of the vehicle trunk was further required.

The purpose of the present invention is to provide an additional means to ensure or complete the installation environment when installing an isolation board that can completely isolate the space where the LPG fuel tank is located from the vehicle compartment even in a vehicle in which the vehicle compartment and the trunk are not physically/structurally isolated. In providing.

Meanwhile, other unspecified purposes of the present invention will be additionally considered within the scope that can be easily inferred from the following detailed description and its effects.

The first aspect of the present invention to achieve the above task is a recessed fuel tank position in the trunk floor where a fuel tank, which is an inner tube-shaped fuel cylinder or a disk-shaped fuel cylinder, is installed in a vehicle in which the vehicle compartment and the trunk are not spatially isolated. It is a pair of side wall brackets that support the square sheet-shaped isolation board isolating from the top on both left and right sides. This pair of side wall brackets has at least two fastening grooves along the longitudinal direction and is attached to the car body by a fastener. It is fastened, and the protruding parts formed adjacent to the left and right ends of the trunk entrance are characterized by forming a storage room of a shape close to a trapezoid.

In addition, the second aspect of the present invention is to isolate the recessed fuel tank position in the bottom of the trunk where the fuel tank, which is an inner tube-shaped fuel cylinder or a disk-shaped fuel cylinder, is installed from the top in a vehicle in which the vehicle compartment and the trunk are not spatially isolated. A pair of side covers installed on a pair of side wall brackets that support a square sheet-shaped isolation board on both left and right sides, and the pair of side wall brackets are fastened with at least two fastening grooves formed along the longitudinal direction. It is fastened to the car body by a sphere, and the protruding parts formed adjacent to the left and right ends of the trunk entrance consist of a storage compartment of a shape close to a trapezoid, and the pair of side covers have a shape close to a trapezoid corresponding to the shape of the storage compartment. It is characterized in that it is inserted into the storage room while having a.

Additionally, in the side cover of the side wall bracket according to a preferred embodiment of the present invention, the upper surface of the side cover preferably includes a grid area and a handle portion.

In short, the present invention installs a side wall bracket and a side cover integrally coupled to the side wall bracket to the trunk. As a result, it was possible to create an environment in which the LPG fuel cylinder can be completely isolated from the vehicle compartment when manufacturing or converting an SUV vehicle whose compartment and trunk are not spatially isolated into an LPG vehicle. At the same time, it was possible to effectively use the space at both corners of the trunk's exterior (entrance side) while responding to the trunk's internal structure and shape.

Meanwhile, it is to be added that even if the effects are not explicitly mentioned herein, the effects described in the following specification and their potential effects expected from the technical features of the present invention are treated as if described in the specification of the present invention.

Hereinafter, with reference to the drawings, we will look at the configuration of the present invention guided by various embodiments of the present invention and the effects resulting from the configuration. In describing the present invention, if it is determined that related known functions may unnecessarily obscure the gist of the present invention as they are obvious to those skilled in the art, the detailed description thereof will be omitted.

LPG fuel cylinders are installed in LPG vehicles. When a long cylindrical bomb (cylindrical bomb) of the type shown in FIGS. 3 and 8 of the prior patent document 2 is installed in the trunk, the space in the trunk becomes very narrow. However, the bigger problem lies in the isolation from the car compartment. In sedan-type vehicles, the cabin and trunk are structurally isolated, but in SUV-type vehicles, the cabin and trunk are not spatially isolated, so it is not desirable to use a long cylindrical cylinder.

Meanwhile, a groove is formed on the floor of the vehicle's trunk room as a loading space for the spare tire. The applicant of the present invention has manufactured and sold LPG vehicles by installing an inner tube-shaped fuel cylinder in the spare tire groove. It was also the donut ^TM Bombay disclosed in Prior Patent Document 1. In Prior Patent Document 2, it was expressed as a “disk-shaped bombe” (Figure 10 of Prior Patent Document 2). However, even if the trunk loading space is not reduced by installing this inner tube-shaped fuel cylinder or disk-shaped fuel cylinder in the spare tire loading space, the problem of isolation between the vehicle compartment and the trunk still remains. In SUV-type vehicles, the trunk trim or trunk carpet only visually conceals the fuel cylinder. Even if a fuel cylinder is installed in the spare tire loading space of this type of vehicle and covered with a trunk carpet, it is difficult to say that it is sufficiently isolated from the vehicle compartment.

The inventor of the present invention solved this problem through the isolation board of FIG. 2. First, let's call the recessed position in the trunk floor where the fuel tank is installed, which has been used as a loading space for the spare tire, the "fuel tank position." Figure 1 schematically illustrates the fuel tank position 10 in one preferred embodiment of the invention.

The fuel tank position 10, indicated by a dotted line, is installed in the trunk 2 of the vehicle 1. The fuel cylinder 11 is connected to and fixed to the vehicle body member by four brackets 12. The isolation board of the present invention isolates the fuel tank position 10 where the fuel cylinder 11 is installed from above. Then, based on this fuel tank position (10), there is an apron (4) at the rear, an extension carpet (5) toward the cabin, and trim (3) on both sides (more specifically, on the left and right). It is an installed side wall bracket, which is the main feature of the present invention. The same applies hereinafter) and is blocked.

Here, two challenges emerge. First, excessive load should not be applied on the fuel cylinder (11). Even if the fuel tank position 10 is isolated from the top with an isolation board described later, it is not possible to simply cover the fuel cylinder 11 from above. Due to the nature of the trunk, a load of more than 100 kg is loaded, and the load is applied entirely to the fuel cylinder 11 through the isolation board, which is undesirable from the viewpoint of safety and stability. Second, as shown, the fuel cylinder 11 is equipped with various configurations to smoothly supply fuel to the engine, as well as a gauge 15 to check the fuel status. Complete isolation of the fuel tank position (10) by the isolation board may also cause inconvenience in managing the gauge (15).

As a configuration to solve the first problem, a plurality of isolation board supports (13) were installed on the bomb bracket (12). An isolation board is placed on this board support (13) to prevent the trunk load from being directly transmitted to the fuel cylinder (11). In addition, as will be described later, both ends of the isolation board are placed on side wall brackets (not shown), and the front and rear ends are placed over the apron (4) and extension carpet (5), respectively, thereby maintaining the vehicle compartment and fuel tank position (10). It physically isolates and simultaneously prevents load transfer to the bomb.

Figure 2 shows a rectangular isolation board 50 installed over the fuel tank position 10 as viewed from above, according to a preferred embodiment of the present invention.

As shown, an isolation board (50) is positioned over the fuel tank position and is surrounded on all sides by vehicle trim (3), apron (4) and extended carpet (5) on both sides. The fuel tank position is physically blocked by the isolation board 10 and each trunk member of the vehicle.

The isolation board 50 of the present invention is composed of an assembly in which a plurality of layers of different materials are stacked and combined to insulate the fuel pump position with sound insulation/sound absorption. The first layer of the top layer is the trunk board and is made of a synthetic resin panel made with a rigid design of approximately 3mm. The known trunk carpet will be placed on top of it. Under the best trunk board, metal plates, rubber sheets, and felt sheets can be sequentially laminated. More preferably, a sound-absorbing material made mainly of non-woven fabric may be interposed between the metal plate and the trunk board to block noise radiated from the metal plate.

A fastening hole (52 in FIG. 3) penetrating the isolation board 50 configured in this way in the vertical direction is installed. The isolation board 50 is installed on the fuel tank position by inserting the fastener 53 into the fastening holes 52 and firmly inserting it into the hole formed in the board support 13 of FIG. 1.

Then, a gauge management hole is formed at a location corresponding to the location of the gauge 15 of the fuel cylinder, and a gauge cover 55 is formed over this gauge management hole. By opening and closing this gauge cover 55, the second problem described above is solved.

The trunk itself is not completely square in shape. By installing side wall brackets that form the left and right side walls of the fuel tank position, the fuel tank position 10 becomes an approximately square-shaped area. Then, a square-shaped isolation board 50 is installed on top of it, which creates a storage area with a depth of approximately radial shape toward the rear of the vehicle among the areas on the left and right outside of the fuel tank position in the side wall bracket. Side covers 210 having approximately the same height as the isolation board 50 are installed in the storage areas on both left and right sides.

When the trim of the left and right vehicles in FIG. 2 is removed, it is revealed that both ends of the isolation board 50 are supported on the left and right side wall brackets 110 and 120 as shown in FIG. 3. In addition, storage rooms are installed at the left and right ends of the side wall brackets (110, 120) at the trunk entrance, and a pair of left and right side covers (210, 220) are installed above these storage rooms, respectively.

Figure 4 shows the shape and structure of the left side wall bracket 110 according to a preferred embodiment of the present invention. The end of the above-described isolation board is raised above the surface of this side wall bracket 110. Also, as shown, a storage compartment 115 having a depth and a shape close to a trapezoid is formed at the longitudinal end (left side of the vehicle apron) of the side wall bracket 110.

Meanwhile, fastening grooves 111, 112, 113, 114, and 116 are formed along the longitudinal direction of the left side wall bracket 110 to secure the side wall bracket 110 to the vehicle body. Fastener bolts are inserted into the fastening grooves (111, 112, 113, 114, 116) to secure the side wall bracket (110) to the car body. In order to securely fix the side wall bracket 110 to the vehicle body, it is recommended that there are at least two fastening directions. Preferably, it is fastened to the side and bottom of the car body. More preferably, fastening grooves are installed on the side, bottom, and rear of the vehicle body, respectively. 111 and 112 are the side fastening grooves of the car body, 113 and 114 are the fastening grooves on the bottom of the car body, and 116 are the rear fastening grooves of the car body.

Figure 5 shows the shape and structure of the right side wall bracket 120 according to a preferred embodiment of the present invention. The end of the above-described isolation board is raised above the surface of this side wall bracket 120. Also, as shown, a storage compartment 125 having a depth and a shape close to a trapezoid is formed at the longitudinal end (right side of the vehicle apron) of the side wall bracket 120.

Meanwhile, fastening grooves 121, 122, 123, 124, and 126 are formed along the longitudinal direction of the right side wall bracket 120 to secure the side wall bracket 120 to the vehicle body. Fastener bolts are inserted into the fastening grooves (121, 122, 123, 124, 126) to secure the side wall bracket (120) to the car body. In order to securely fix the side wall bracket 120 to the vehicle body, it is recommended to have at least two fastening directions. Preferably, it is fastened to the side and bottom of the car body. More preferably, fastening grooves are installed on the side, bottom, and rear of the vehicle body, respectively. 121 and 122 are the side fastening grooves of the car body, 123 and 124 are the fastening grooves on the bottom of the car body, and 126 are the rear fastening grooves of the car body.

Vehicle tools can be stored in this storage compartment 125, and a Velcro band 127 can be installed to prevent the stored tools from coming out. Velcro tape improves ease of attachment and detachment.

The reason why the storage compartments 115 and 125 of this shape and structure are installed on the side wall brackets 110 and 120 is that the geometric shape of the inner plane of the trunk of the vehicle is not square, but the geometric shape of the above-described isolation board is square. This is because it consists of In addition, it was necessary to create the structure and shape of the side wall brackets 110 and 120 according to the structure and shape of the interior of the left and right trims of the vehicle trunk. Therefore, protruding portions were created on the side wall brackets (110, 120) adjacent to the left and right ends of the trunk entrance, and the portions were formed in a shape close to a trapezoid. In addition, the fastening groove part that is fastened to the side of the car body is designed to protrude toward the car body to facilitate fastening to the car body. Meanwhile, it should be added that sufficient consideration was given to air circulation in designing the shape and structure of the side bracket of the present invention. Additionally, in the case of the right side wall bracket 120, it was necessary to design the bracket shape to accommodate the passage of the bomb hose through it.

The design of vehicles varies by category and brand. Therefore, it should be noted that the shape and structure of the side wall brackets 110 and 120 can be modified in various ways.

Meanwhile, when a square-shaped isolation board is installed on the surface of the pair of left and right side wall brackets 110 and 120 as above, the portions corresponding to the storage rooms 115 and 125 on both the left and right sides are not covered by the isolation board. If this is left as is, eventually a fault will form on the surface of the trunk floor. 6 and 7 illustrate a pair of left and right side covers according to a preferred embodiment of the present invention.

As shown in FIG. 6, the side cover 210 for the left side wall bracket has a shape close to a quadrilateral corresponding to the shape of the storage chamber 115.

The side surface 215 of the side cover 210 for the left side wall bracket is in close contact with the storage chamber 115 toward the upper surface of the bracket on which the isolation board is placed. The upper surface 217 is in close contact with the upper surface of the storage chamber 115, and the protrusion 218 having a depth toward the bottom also slides along the inner surface of the storage chamber 115.

The surface of the side cover 210 for the left side wall bracket includes a grid area 211 composed of a plurality of grids and a handle portion 213. By configuring the surface in this way, not only can the inside of the storage chamber 115 be clearly visible, but it also becomes easy to hold and attach. In particular, air circulation at the fuel pump position can be ensured by configuring the surface with the grid area 211. If air circulation is not good, there is a risk of moisture forming inside the vehicle. The same applies below.

As shown in FIG. 7, the side cover 220 for the right side wall bracket has a shape close to a quadrilateral corresponding to the shape of the storage chamber 125.

The side surface 225 of the side cover 220 for the right side wall bracket is in close contact with the storage chamber 125 toward the upper surface of the bracket on which the isolation board is placed. The upper surface 227 is in close contact with the upper surface of the storage chamber 115, and the protrusion 228 having a depth toward the bottom also slides along the inner surface of the storage chamber 125.

The surface of the side cover 220 for the right side wall bracket includes a grid area 221 composed of a plurality of grids and a handle portion 223.

8 and 9, the side cover 210 for the left side wall bracket serves as a cover for the corresponding storage compartment 115 of the left side wall bracket 110 of a shape close to a trapezoid, and the side cover 210 for the right side wall bracket The cover 220 serves as a cover for the storage compartment 125 of the corresponding right side wall bracket 120, which has a shape close to a trapezoid.

In a preferred embodiment of the present invention, the thickness of the isolation board assembly that isolates the fuel tank position from above and the thickness of the side surfaces 215 and 225 of the side covers 210 and 220 are approximately equal. By doing so, the plane when the isolation board assembly is installed and the plane when the side covers 210 and 220 are installed in the side wall bracket storage chambers 115 and 125 can be maintained at approximately the same height. It may be necessary to insert or attach sound-absorbing materials to block and absorb various noises generated from the fuel cylinder at various locations where the side wall bracket is installed. The trunk carpet is then covered entirely over that flat surface.

The scope of protection of the present invention is not limited to the description and expression of the embodiments explicitly described above. In addition, it is to be added once again that the scope of protection of the present invention may not be limited due to changes or substitutions that are obvious in the technical field to which the present invention pertains.
