Description

Technical Field

[0001] This utility model relates to the field of vehicle assembly technology, specifically to a gas valve mounting bracket. Background Technology

[0002] The refueling valve on a vehicle is used to safely and efficiently fill the onboard gas tank with fuels such as compressed natural gas or hydrogen, and its installation stability is crucial. A stable installation ensures a tight, leak-free connection during refueling, avoiding loosening and potential hazards caused by vibration or external impact; it also guarantees long-term reliability, reduces maintenance frequency, and improves the safety and efficiency of vehicle operation, which is of great significance for ensuring the safety of drivers and passengers.

[0003] The existing gas filling valve is mounted on the vehicle frame via a mounting bracket. The traditional mounting bracket consists of two main components, requiring assembly with six M8 bolts and nuts. One of the main components also requires pre-assembly of two sub-components through welding, making the assembly process cumbersome and affecting assembly efficiency. Secondly, the two main components need to be spliced ​​end to end and installed in a staggered manner, resulting in a loose structure, occupying a large amount of space, and making it difficult to adapt to the compact layout requirements of vehicles. Installation errors may affect subsequent assembly. Furthermore, long-term use has revealed redundant components on the main components, such as seals and wiring harness mounting strips, which have extremely low utilization efficiency and redundancy in the overall structure and standard parts. Utility Model Content

[0004] The present invention aims to provide a gas valve mounting bracket to solve the problem of unreasonable structure of existing mounting brackets.

[0005] The basic solution provided by this utility model is: a gas valve mounting bracket, including a protective cover and a connecting part;

[0006] The protective cover includes a U-shaped extension extending from the front end to the rear end; a protective plate is hinged to the front end of the U-shaped extension; at least one side of the U-shaped extension has a through hole; and the rear end of the bottom surface of the U-shaped extension has an opening.

[0007] One end of the connector is mounted inside the U-shaped extension by at least two mounting pieces, and is located above the opening and below the through hole, while the other end extends beyond the cover in the rearward direction.

[0008] Furthermore, the protective plate has a protruding structure at the location corresponding to the gas filling valve, and it protrudes towards the front end.

[0009] Furthermore, at least one side of the U-shaped extension and the non-hinged side of the protective plate is provided with a fastening element.

[0010] Furthermore, the side of the U-shaped extension that is hinged to the protective plate is provided with a flange that bends in a Z-shape towards the rear end; the end face after bending is parallel to the protective plate; and a narrow guard is provided at the end of the flange that is close to the bottom surface of the U-shaped extension along the direction parallel to the protective plate.

[0011] Furthermore, there are two mounting components, which are symmetrically installed on both sides of the connection.

[0012] Furthermore, the mounting component has a Z-shaped structure with its top and bottom surfaces parallel; the top surface of the mounting component is connected above the top surface of the connecting part; the bottom surface of the mounting component is connected to the bottom surface of the U-shaped extension and is located next to the opening.

[0013] Furthermore, the connecting part has a long strip structure, with its two sides bending towards the bottom surface of the U-shaped extension along its extension direction.

[0014] Furthermore, the bottom front end of the connector is chamfered near the front end of the U-shaped extension opening, and the width of the connector is smaller than the width of the opening; the top front end of the connector has a first mounting hole provided as needed.

[0015] Furthermore, a mounting plate is installed at the end of the connecting part away from the U-shaped extension; a second mounting hole is provided on the mounting plate as needed.

[0016] Furthermore, the connecting portion has a groove recessed toward the bottom surface of the U-shaped extension along its extension direction.

[0017] The working principle and advantages of this utility model are as follows:

[0018] Compared to existing technologies, this solution optimizes the structure, integrating the refueling valve mounting bracket into a single main component. It requires fewer than six (typically three) M8 bolts for direct mounting to the vehicle frame, eliminating the need for reassembly of multiple main components and mitigating assembly errors. This simplifies the assembly process and improves efficiency. The overall structure is streamlined and compact, fitting the compact layout requirements of vehicles. It boasts high integration, uses fewer materials and standard parts, resulting in lighter weight and lower cost. The structure is strong and reliable, ensuring continuous stability. Furthermore, the design of the U-shaped extension opening on the bottom of the cover and the connection mechanism allows for fine-tuning of the mounting position, enhancing the bracket's flexibility and versatility.

[0026] The markings in the accompanying drawings include: protective cover 1, U-shaped extension 11, side 111, through hole 1111, bottom surface 112, opening 1121, flange 113, narrow guard 114, protective plate 12, protrusion 121, fastener 13, mounting part 14, support structure 141, connecting part 2, mounting plate 21, groove 22, first mounting hole 23, and second mounting hole 24. Detailed Implementation

[0027] The following detailed explanation illustrates the specific implementation methods:

[0028] The basic implementation examples are as follows: Figure 1 , Figure 2 and Figure 3 As shown: A gas valve mounting bracket includes a protective cover 1 and a connecting part 2;

[0029] The protective cover 1 includes a U-shaped extension 11 extending from the front end to the rear end; a protective plate 12 is hinged to the front end of the U-shaped extension 11; at least one side 111 of the U-shaped extension 11 has a through hole 1111; and the rear end of the bottom surface 112 of the U-shaped extension 11 has an opening 1121.

[0030] One end of the connecting part 2 is installed in the U-shaped extension 11 by at least two mounting pieces 14 and is located above the opening 1121 and below the through hole 1111, while the other end extends beyond the protective cover 1 in the rearward direction.

[0031] Specifically:

[0032] by Figure 1 The arrows indicate the direction from the front end to the back end, with the arrows pointing towards the back end. Figure 2 The direction indicated by the arrow defines the width direction.

[0033] The protective plate 12 has a protrusion 121 structure at the installation position of the gas filling valve, and the protrusion 121 is forward. Since there is a pull ring on the gas filling valve, it will shake during driving. Therefore, the protective plate 12 has a protrusion 121 structure at the corresponding position. This not only meets the requirement of avoiding the pull ring, but also reduces the overall size of the protective plate 12 by using the local protrusion 121, making the overall structure compact.

[0034] The upper and lower sides of the protective plate 12 are both bent towards the rear end for a first distance and then bent and extended relative to each other. In this embodiment, the bending angle is 90 degrees. This design of the protective plate 12 structure can enhance the structural strength, improve the installation stability, provide additional functions, and adapt to specific installation environment requirements.

[0035] like Figure 4 and Figure 5 As shown, the opening 1121 of the U-shaped extension 11 is located in the center of the rear end of the bottom surface 112. In addition, the connecting part 2 is installed inside the U-shaped extension 11. That is, the width of the connecting part 2 is smaller than the width of the protective cover 1. The overall width of the bracket is determined by the width of the protective cover 1, which ensures the uniformity and compactness of the overall structure and avoids misalignment and large space occupation.

[0036] like Figure 6 and Figure 7 As shown, there is a gap on the hinge side of the U-shaped extension 11 and the protective plate 12. The gap is designed to ensure that the protective plate 12 can be opened and closed smoothly, while ensuring that the gap is small, thus ensuring that the protective plate 12 can effectively protect the internal gas filling valve and its components.

[0037] At least one side of the U-shaped extension 11 and the protective plate 12 on the non-hinged side is provided with a fastening member 13. In this embodiment, a fastening member 13 is provided on the opposite side of the hinge.

[0038] like Figure 1 , Figure 2 and Figure 6 As shown, the U-shaped extension 11 is hinged to the side of the protective plate 12 on the opposite side (i.e., as shown) Figure 1 As shown in this embodiment, the U-shaped extension 11 (with the side of the fastener 13) has a Z-shaped bend 113 that bends towards the rear end. The Z-bend angle is 90 degrees, and the last surface after bending is parallel to the protective plate 12. A narrow baffle 114 extends from one end of the flange 113 near the bottom surface 112 of the U-shaped extension 11 along the direction parallel to the protective plate 12. In this embodiment, it extends to the hinge side. The flange 113 and the narrow baffle 114 can be integrally formed with the U-shaped extension 11. When the protective plate 12 is locked onto the U-shaped extension 11 by the fastener 13, the improved Z-shaped bend flange 113 and narrow baffle 114 can replace the traditional sealing components, achieving a shielding function while adapting to the working environment, effectively reducing the number of parts, and improving assembly efficiency.

[0039] likeFigure 4 As shown, there are two mounting parts 14, symmetrically installed on both sides of the connecting part 2; as Figure 2 As shown, the mounting component 14 has a Z-shaped structure, with its top and bottom surfaces 112 parallel. In this embodiment, the Z-shape is bent at 90 degrees. The top surface of the mounting component 14 is fixedly connected to the top surface of the connecting part 2 by welding. The bottom surface 112 of the mounting component 14 is fixedly connected to the bottom surface 112 of the U-shaped extension component 11 by bolts, located next to the opening 1121. A support structure 141 is provided at the bend of the mounting component 14 away from the connecting part 2. In this embodiment, it is a triangular structure to improve the connection stability.

[0040] like Figure 3 and Figure 4 As shown, the connecting part 2 has a long strip structure with an extension length of 346-348mm, preferably 347.5mm. Its two sides along the extension direction bend towards the bottom surface 112 of the U-shaped extension 11. In this embodiment, the connecting part 2 has a U-shaped structure, with the U-shaped opening 1121 facing the bottom surface 112 of the U-shaped extension 11. The height of the connecting part 2 needs to ensure that it does not exceed the through hole 1111 of the U-shaped connector after installation, to avoid excessive height that would prevent the gas valve pipeline from being installed through the through hole 1111. The height can be 28-30mm, preferably 29mm. The connecting part 2 has a groove 22 recessed towards the bottom surface 112 of the U-shaped extension 11 along its extension direction to improve structural strength. In this embodiment, the length of the groove 22 is 85%-90% of the length of the connecting part 2. During installation, the mounting part 14 is located on both sides of the front end of the groove 22. The entire connecting part 2, based on the traditional structure, eliminates redundant components, resulting in a simpler and more compact structure with a smaller footprint. The overall structure and dimensions are designed to meet both support strength and the installation requirements of the gas filling valve, including installation process and space. The front end of the connecting part 2 does not extend beyond the front end of the opening 1121, providing suitable installation space for the gas filling valve. A chamfer is provided at the bottom of the front end of the connecting part 2 near the front end of the opening 1121 of the U-shaped extension 11, and the width of the connecting part 2 is slightly smaller than the width of the opening 1121. This creates a gap between the connecting part 2 and the edge of the opening 1121, which can be 1-2 mm, preferably 1 mm. This prevents interference between the connecting part 2 and the edge of the opening 1121, while also providing some clearance for fine-tuning the position when installing different types of gas filling valves.

[0041] like Figure 2 As shown, the top surface of the front end of the connecting part 2 has a first mounting hole 23 provided as needed for installing the gas valve and its components. The number and position of the mounting holes are set according to the installation needs of the gas valve and its components. In this embodiment, there are two holes, located at the front end of the mounting part 14.

[0042] like Figure 3As shown, a mounting plate 21 is installed at the end of the connecting part 2 away from the U-shaped extension 11. The height of the mounting plate 21 is greater than the height of the connecting part 2 and less than the height of the protective cover part 1; Figure 2 As shown, the mounting plate 21 has second mounting holes 24 provided as needed for connection with the vehicle frame. In this embodiment, there are three second mounting holes 24, which are connected to the vehicle frame by three M8 bolts.

[0043] In practical use:

[0044] The protective cover 1 and connecting part 2 of the mounting bracket in this solution have been pre-assembled and integrated according to the above structure by the mounting part 14; during the integration and assembly process, the position of the connecting part 2 and the opening 1121 of the bottom surface 112 of the U-shaped extension 11 can be finely adjusted, and the distance between the connecting part 2 and the protective plate 12 can be finely adjusted to adapt to the installation position requirements of the corresponding gas filling valve and its components, thereby improving the structural flexibility.

[0045] In use, the connection between the mounting bracket and the vehicle frame can be completed simply by using the second mounting hole 24 on the mounting plate 21 and three M8 bolts. During the connection process, only the alignment of the mounting bracket and the vehicle frame needs to be adjusted, without any installation errors in other assembly structures.

[0046] This embodiment provides a gas valve mounting bracket. Compared with existing technologies, this solution optimizes the structure, integrating the gas valve mounting bracket into a single main component. It requires fewer than six (typically three) M8 bolts for direct mounting on the vehicle frame, eliminating the need for reassembly of multiple main components, removing concerns about installation errors, simplifying the assembly process, and improving assembly efficiency. The overall structure is streamlined and compact, fitting the compact layout requirements of vehicles; it has a high degree of integration, uses fewer materials and standard parts, is lightweight, and has low cost; it also boasts high structural strength and reliability, ensuring continuous stability.
