Description

Technical Field

[0001] The utility model relates to the technical field of mounting brackets, and in particular to a mounting bracket for an FTIV valve. Background Art

[0002] The FTIV valve, or fuel tank isolation valve, plays an important role in the automotive fuel system, especially in electric or hybrid vehicles, where it is used to isolate the fuel supply line between the fuel tank and the engine. In traditional internal combustion engine vehicles, the connection between the fuel tank and the engine is usually direct, but in electric or hybrid vehicles, since the vehicle may be in non-internal combustion engine driving mode for a long time, a mechanism is needed to control the opening and closing of the fuel system to improve safety and meet emission standards.

[0003] The existing FTIV valve is usually placed directly on one side of the fuel tank and is simply fixed. If the driving environment is harsh or it is often subjected to severe vibration, the FTIV valve may be unstable and slip, resulting in safety hazards. Utility Model Content

[0004] The utility model provides a mounting bracket for an FTIV valve, which solves the problem in the related art that the FTIV valve may slip due to unstable fixing when the driving environment is bad or the valve is often subjected to severe vibration.

[0005] The technical solution of the utility model is as follows:

[0006] A mounting bracket for an FTIV valve, used for carrying and fixing a valve body of the FTIV valve, comprising:

[0007] A frame body is arranged on the fuel tank, one side of the frame body is in contact with the fuel tank, and the other side of the frame body is used to receive the valve body;

[0008] A limiting column, arranged on the frame;

[0009] The first limit block is arranged on the frame, and the first limit block is located at one side of the limit column. The limit column, the first limit block and the frame together constitute a limit space, and the limit space is used to limit the movement of the valve body.

[0010] As a further technical solution, the valve body has a first mounting portion, the first mounting portion has a through hole, and further includes:

[0011] A nut, arranged on the limiting column;

[0012] A mounting bolt passes through the through hole and is detachably connected to the nut.

[0013] As a further technical solution, the limiting column has a limiting hole, and the nut is located in the limiting hole.

[0014] As a further technical solution, the nut is provided with an anti-slip groove, and further comprises:

[0015] A clamping platform is arranged in the limiting hole, the clamping platform is clamped with the anti-slip groove, and the clamping platform is used to prevent the nut from slipping out of the limiting hole.

[0016] As a further technical solution, the valve body has a second mounting portion, the second mounting portion has a slot, and further includes:

[0017] The second limit block is arranged on the first limit block. After the valve body is installed, the second limit block passes through the slot.

[0018] As a further technical solution, the frame is provided with a plurality of weight-reducing holes.

[0019] As a further technical solution, it also includes:

[0020] The wire harness plate is arranged on a side of the first limiting block away from the limiting column, and the wire harness plate has a wire harness hole.

[0021] The working principle and beneficial effects of the utility model are:

[0022] In the utility model, the frame is an important part of the mounting bracket. The frame is connected to the fuel tank by welding or bonding, etc., to ensure that the fuel tank can be well connected to the frame, and to prevent the frame from falling and causing the valve body installed on the frame to fall. The limiting column and the first limiting block are arranged on the frame, and the valve body is installed in the limiting space composed of the limiting column, the limiting block and the frame. The limiting space can well limit the valve body, ensuring that the valve body will not slide or roll in the limiting space after being installed in the limiting space, thereby ensuring the stability of the valve body. The frame itself is smaller than the valve body, and it is more convenient and quick to install the valve body, which simplifies the installation steps and improves the efficiency of the installation. After the installation is completed, even if the fuel tank itself vibrates violently, the valve body will not tilt or rotate, thereby improving the overall stability.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0032] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0033] Reference Figure 1~Figure 5, which is the first embodiment of the utility model, proposes a mounting bracket for an FTIV valve, which is used to carry and fix the valve body 8 of the FTIV valve, including: a frame body 1 is arranged on the fuel tank, one side of the frame body 1 is in contact with the fuel tank, and the other side of the frame body 1 is used to receive the valve body 8; a limit column 110 is arranged on the frame body 1; a first limit block 120 is arranged on the frame body 1, and the first limit block 120 is located on one side of the limit column 110, and the limit column 110, the first limit block 120 and the frame body 1 together form a limit space 121, and the limit space 121 is used to limit the movement of the valve body 8.

[0034] In this embodiment, the frame 1 is an important part of the mounting bracket. The frame 1 is connected to the fuel tank by welding or bonding, etc., to ensure that the fuel tank can be well connected to the frame 1, and to prevent the frame 1 from falling and causing the valve body 8 installed on the frame 1 to fall. The limiting column 110 and the first limiting block 120 are arranged on the frame 1, and the valve body 8 is installed in the limiting space 121 composed of the limiting column 110, the limiting block and the frame 1. The limiting space 121 can well limit the valve body 8, ensuring that the valve body 8 will not slide or roll in the limiting space 121 after being installed in the limiting space 121, thereby ensuring the stability of the valve body 8. The frame 1 itself is smaller than the valve body 8, and it is more convenient and quick to install the valve body 8, which simplifies the installation steps and improves the efficiency of the installation. After the installation is completed, even if the fuel tank itself vibrates violently, the valve body 8 will not tilt or rotate, thereby improving the overall stability.

[0035] Furthermore, the valve body 8 has a first mounting portion 210, the first mounting portion 210 has a through hole 211, and also includes: a nut 3, which is arranged on the limiting column 110; a mounting bolt 4, the mounting bolt 4 passes through the through hole 211 and is detachably connected to the nut 3; the limiting column 110 has a limiting hole 510, and the nut 3 is located in the limiting hole 510.

[0036] In this embodiment, the limiting space 121 can only play a certain limiting role on the valve body 8. At the same time, the valve body 8 has a first mounting portion 210, and the first mounting portion 210 is mounted on the limiting column 110 by means of mounting bolts 4. The first mounting portion 210 is fixed by means of the mounting bolts 4, and at the same time, the valve body 8 is fixed with the limiting space 121. Even if a huge vibration occurs, the valve body 8 will neither vibrate nor slip on the frame 1. The two positions together firmly fix the valve body 8 to prevent the valve body 8 from loosening or detaching from the frame 1.

[0037] Furthermore, the nut 3 has an anti-slip groove 310 , and also includes: a clamping platform 111 disposed in the limiting hole 510 , the clamping platform 111 is clamped with the anti-slip groove 310 , and the clamping platform 111 is used to prevent the nut 3 from slipping out of the limiting hole 510 .

[0038] In this embodiment, the anti-slip groove 310 is arranged on the nut 3, and the limiting piece is located on the limiting column 110. When the anti-slip groove 310 on the nut 3 cooperates with the limiting hole 510, the limiting hole 510 is used to clamp the nut 3 to prevent the nut 3 from separating from the limiting piece, thereby ensuring the stability of the valve after installation. At the same time, the shape of the nut 3 is different from the common hexagonal shape, and the shape of the limiting hole 510 corresponding to it corresponds to the nut 3, which not only simplifies the installation steps, but also prevents the nut 3 from rotating relative to the limiting piece, thereby improving the strength of the connection.

[0039] Furthermore, the valve body 8 has a second mounting portion 220 , and the second mounting portion 220 has a slot 230 . The valve body 8 also includes: a second limit block 7 is arranged on the first limit block 120 , and after the valve body 8 is installed, the second limit block 7 passes through the slot 230 .

[0040] In this embodiment, the second limit block 7 is connected and clamped to the second mounting portion 220. After the second limit block 7 and the mounting bolt 4 are clamped together, the valve body 8 can be further prevented from being separated from the bracket, ensuring that the valve body 8 is completely restricted on the bracket, thereby improving the stability of the valve body 8. At the same time, the slot hole 230 on the second mounting portion 220 will be restricted from moving after being installed into the first limit block 120, thereby preventing the valve body 8 from being separated from the first limit block 120, thereby improving the overall fixing strength.

[0041] Furthermore, the frame body 1 has a plurality of weight-reducing holes 6 .

[0042] In this embodiment, the overall weight of the fuel tank is not very heavy, so the weight it can bear is also limited. When the frame 1 is connected to the fuel tank and the valve body 8 is installed, the overall weight will be very heavy. When the motor vehicle is under the action of inertia or acceleration, it may cause excessive pressure on the side wall of the fuel tank. Therefore, multiple weight-reducing holes 6 are designed to reduce the weight of the frame 1, which can not only reduce the possibility of connection detachment. Moreover, through the design of the weight-reducing holes 6, the frame 1 forms a mesh structure, which improves the strength of the frame 1.

[0043] Furthermore, it also includes: a wire harness plate 240 is arranged on the first limiting block 120, and a wire harness hole 231 is provided on the wire harness plate 240.

[0044] In this embodiment, the wire harness plate 240 is used to bundle the control lines connected to the valve body 8 to prevent the lines from being cluttered. Even if severe vibration occurs, the lines will not be separated from the wire harness plate 240, thereby reducing the risk of failure of the valve body 8 during use, and also preventing the risk of short circuits or short circuits caused by shaking of the lines.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
