Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a connection component and a vehicle. Background Technology

[0002] As national regulations on emissions from traditional gasoline vehicles become increasingly stringent, liquefied natural gas (LNG) trucks are gaining more and more attention from automakers. The gas supply system is a crucial component of this system, which typically includes a storage tank, a carburetor, a filter, and a gas injection system. The carburetor is a vital component that converts the liquid fuel in the storage tank into gaseous fuel. The carburetor is usually connected to the gas cylinder via a vaporization pipe. To minimize piping, the vaporization pipe is often placed on the vehicle's crossbeam, directly below the gas cylinder. During vehicle operation, the crossbeam is prone to twisting, which can loosen the connection between the carburetor and other structures, leading to fluid leakage within the carburetor. Furthermore, the gas cylinder is usually placed directly on the crossbeam, resulting in a small distance between the cylinder and the carburetor, affecting airflow at the carburetor and consequently impacting its vaporization efficiency.

[0003] Existing technologies increase the space for the carburetor by adding a connector between the gas cylinder bracket and the vehicle frame. However, such connectors typically have a fixed structure and are not very versatile when dealing with gas cylinders of different radial dimensions, which increases vehicle costs.

[0004] Therefore, a connection component and vehicle are needed to solve the above problems. Utility Model Content

[0040] Example 1

[0041] like Figures 1 to 3 As shown, this embodiment provides a connection component, which includes a first connection structure 10. The first connection structure 10 includes an upper connection unit 11 and a lower connection unit 12. The upper connection unit 11 includes an upper body 111 and a first connection part. The upper end of the upper body 111 is used to connect to the gas cylinder bracket 3, and the first connection part is disposed at the lower end of the upper body 111. The lower connection unit 12 includes a lower body 121 and a plurality of second connection parts. The lower end of the lower body 121 is used to connect to the vehicle frame 2, and the plurality of second connection parts are disposed at the upper end of the lower body 121. The plurality of second connection parts are spaced apart along the vehicle driving direction. The first connection part can be selectively connected to one of the second connection parts to connect the upper body 111 and the lower body 121. Specifically, in this embodiment, the upper end of the upper body 111 and the gas cylinder bracket 3 are detachably connected, the lower end of the lower body 121 is connected to the vehicle frame 2, and the upper end of the lower body 121 is provided with a plurality of second connecting parts spaced apart along the vehicle driving direction. The first connecting part provided at the lower end of the upper body 111 can be connected to any one of the second connecting parts, thereby allowing the position of the upper body 111 relative to the lower body 121 in the vehicle driving direction to be adjustable. This allows the first connecting structure 10 to be applicable to gas cylinder brackets 3 that install gas cylinders 4 of different diameters, thereby meeting the usage requirements of different vehicles. Furthermore, the setting of the connecting component increases the installation height of the gas cylinder 4, thereby ensuring the installation space of the vaporizer, improving the vaporization effect, and ensuring performance.

[0042] Specifically, in this embodiment, four first connecting structures 10 are provided, and the four first connecting structures 10 are respectively connected to the four installation positions of the gas cylinder bracket 3. By connecting the first connecting parts of the four first connecting structures 10 to different second connecting parts, the connecting assembly can be adapted to gas cylinders of different diameters, thereby improving the applicability and versatility of the connecting assembly.

[0043] Furthermore, such as Figure 2 and Figure 3As shown, the first connecting part consists of a set of first connecting holes 113 formed on the upper body 111, and the second connecting part consists of several sets of second connecting holes 1213 formed on the lower body 121. Each set of first connecting holes 113 can be correspondingly matched with any set of second connecting holes 1213. Fasteners are inserted through the mating first connecting holes 113 and second connecting holes 1213 to connect the second upper plate 1112 and the second lower plate 1212. Specifically, in this embodiment, the first connecting part includes two first connecting holes 113, and there are two second connecting parts, each including two second connecting holes 1213. In this embodiment, three second connecting holes 1213 are spaced apart to form two second connecting parts. This arrangement can improve the positional accuracy when the first connecting part and the second connecting part are connected, and there is sufficient load-bearing material between two adjacent second connecting holes 1213, thereby ensuring the connection stability of the first connecting part and the second connecting part and effectively avoiding deformation of the first connecting structure.

[0044] Furthermore, such as Figure 2 and Figure 3 As shown, the upper body 111 includes a first upper plate 1111 and a second upper plate 1112, which are set at an angle. The lower body 121 includes a first lower plate 1211 and a second lower plate 1212, which are set at an angle. The second upper plate 1112 and the second lower plate 1212 are fitted together. A first connecting hole 113 is opened in the second upper plate 1111 and a second connecting hole 1213 is opened in the second lower plate 1212. Specifically, in this embodiment, the included angle between the first upper plate 1111 and the second upper plate 1112 is 90°, and the included angle between the first lower plate 1211 and the second lower plate 1212 is 90°. Both the upper body 111 and the lower body 121 have an L-shaped structure. When the upper body 111 and the lower body 121 are connected, the second upper plate 1112 and the second lower plate 1212 fit together. This arrangement makes the lower body 121 provide better support for the upper body 111, thereby improving the installation stability of the gas cylinder bracket 3 and ensuring the installation stability of the gas cylinder 4. At the same time, it increases the contact area between the upper body 111 and the lower body 121, ensuring that both the first connecting hole 113 and the second connecting hole 1213 have a large diameter, which can ensure the diameter of the fastener, thereby improving the support capacity.

[0045] Specifically, in this embodiment, the fastener includes a fastening bolt and a fastening nut. The fastening bolt passes through the first connecting hole 113 and the second connecting hole 1213 and is threadedly connected to the fastening nut, thereby connecting the second upper plate 1112 and the second lower body 121.

[0046] Specifically, in this embodiment, please refer to Figure 2 and Figure 3 In order to reduce the overall weight of the connecting components, the first upper plate 1111, the second upper plate 1112, the first lower plate 1211 and the second lower plate 1212 are all provided with weight reduction holes 32. The weight reduction holes 32 are located in the middle area, which can avoid affecting the overall strength of the first connecting structure 10, improve the convenience of use, and ensure the overall strength.

[0047] Specifically, in this embodiment, a stiffener is provided between the first upper plate 1111 and the second upper plate 1112 to ensure the structural strength between the first upper plate 1111 and the second upper plate 1112. Similarly, a stiffener is also provided between the first lower plate 1211 and the second lower plate 1212 to ensure the structural strength between the first lower plate 1211 and the second lower plate 1212, avoid deformation, and improve the stability of the first connecting structure 10.

[0048] Further, please refer to Figure 2 and Figure 3 The second upper plate 1112 is provided with a first post 1113 corresponding to the second connecting hole 1213, and the first connecting hole 113 is opened on the corresponding first post 1113; and / or, the second lower plate 1212 is provided with a second post 1215 corresponding to the first connecting hole 113, and the second connecting hole 1213 is opened on the corresponding second post 1215. Specifically, in this embodiment, the first connecting hole 113 is opened on the first post 1113, and the second connecting hole 1213 is opened on the second post 1215. The arrangement of the first post 1113 and the second post 1215 can increase the structural strength at the first connecting hole 113 and the second connecting hole 1213, avoid cracking caused by stress, and ensure the stability of the connection between the second upper plate 1112 and the second lower plate 1212.

[0049] Specifically, in this embodiment, a reinforcing rib 31 is provided between any one of the first columns 1113 and at least one other first column 1113, and a reinforcing rib 31 is provided between any one of the second columns 1215 and at least one other second column 1215, which can improve the strength of the first connecting structure 10, and improve its service life and installation stability. Specifically, in this embodiment, please refer to... Figure 2The first upper plate 1111 is provided with four sixth columns 1114, which are respectively arranged at the four corners of the rectangular structure. Each of the four sixth columns 1114 is provided with a sixth connecting hole 1115. The reinforcing ribs 31 are arranged along the periphery of the first upper plate 1111, so that the four sixth columns 1114 are connected to the reinforcing ribs 31, thereby improving the structural strength of the first upper plate 1111 and ensuring safety during use. The gas cylinder bracket 3 is provided with four mounting holes, which are connected to the four sixth connecting holes 1115 in a one-to-one correspondence. Fasteners are inserted through the mounting holes and the sixth connecting holes 1115 to connect the gas cylinder bracket 3 and the first upper plate 1111.

[0050] Further, please refer to Figure 3 The lower connecting unit 12 also includes a third connecting portion. Several third connecting portions are disposed at the second end of the lower body 121 and are spaced apart along the vehicle height direction. Any one of the third connecting portions can detachably connect the lower body 121 and the frame 2. Specifically, in this embodiment, several third connecting portions are spaced apart along the vehicle height direction at the second end of the lower body 121. Different third connecting portions allow for adjustment of the height of the lower connecting unit 12, resulting in different heights for the gas cylinder bracket 3 connected to the connecting assembly. This allows for adjustment of the carburetor's installation space, ensuring that the carburetor's vaporization efficiency meets usage requirements.

[0051] Further, please refer to Figure 3 The third connection portion consists of several third connection holes 1214 formed in the first lower body 121, and these third connection holes 1214 are spaced apart along the vehicle's driving direction. Specifically, in this embodiment, the lower body 121 is provided with two third column assemblies, which are spaced apart along the vehicle's height direction. Each third column assembly includes five third columns 1216 spaced apart along the vehicle's driving direction. Each third column 1216 has a third connection hole 1214. The five third connection holes 1214 formed on the five third columns 1216 in the same row constitute the aforementioned third connection portion. The frame 2 is provided with five spaced first connection through holes. Fastening bolts pass through the third connection holes 1214 and the first connection through holes in sequence and are threaded into the nuts to connect the lower body 121 to the frame 2. This arrangement allows for the selection of third connection portions of different heights, thereby changing the height of the overlapping portion between the lower body 121 and the frame 2, and thus changing the height of the gas cylinder bracket 3, improving versatility and flexibility.

[0052] Specifically, in other embodiments, the number of third connecting parts and the number of third connecting holes 1214 in each third connecting part can be specifically set according to actual use, and are not limited here.

[0053] Specifically, in this embodiment, a reinforcing rib 31 is also provided between two adjacent third columns 1216 to ensure the stability of the bolt connection, avoid defects such as cracks caused by stress concentration, and thus ensure safety during use.

[0054] Specifically, in this embodiment, both the upper body 111 and the lower body 121 are manufactured by a combination of casting and machining processes, which results in lower processing costs and higher product consistency, thereby reducing overall vehicle costs and improving the user experience.

[0055] Furthermore, the upper connecting unit 11 also includes a first support portion 112, which protrudes from the upper body 111 and is used to provide support for the gas cylinder support 3. Specifically, in this embodiment, the upper body 111 is connected to the gas cylinder support 3, and the first support portion 112 provides support for the gas cylinder support 3. Together, they ensure the stability of the gas cylinder support 3.

[0056] This embodiment also provides a vehicle, which includes a frame 2, a gas cylinder 4, and a gas cylinder bracket 3. A connecting component is connected between the frame 2 and the gas cylinder bracket 3, and the gas cylinder 4 is installed on the gas cylinder bracket 3. By providing the aforementioned connecting component, this vehicle can lift the gas cylinder bracket 3, thereby ensuring the installation space for the carburetor. This is beneficial for improving the vaporization efficiency of the carburetor and the combustion efficiency of the vehicle, thereby improving the performance of the vehicle. It can also ensure the installation of gas cylinders 4 of different diameters, and has good versatility and flexibility.

[0057] Example 2

[0058] like Figure 4 As shown, this embodiment provides a connecting component. The difference between the connecting component in this embodiment and the connecting component in embodiment 1 is that the connecting component in this embodiment also includes a second connecting structure 20. The cooperation between the second connecting structure 20 and the first connecting structure 10 can reduce production costs and improve the installation stability of the gas cylinder bracket 3.

[0059] Specifically, the first connecting structure 10 and the second connecting structure 20 are spaced apart. The second connecting structure 20 includes a connecting body 21 and a fourth connecting part. A plurality of fourth connecting parts are disposed at the upper end of the connecting body 21 and are spaced apart along the vehicle travel direction. Any one of the fourth connecting parts can connect the connecting body 21 to the gas cylinder bracket 3. The lower end of the connecting body 21 is used to connect to the vehicle frame 2. Specifically, in this embodiment, the connecting assembly includes two first connecting structures 10 and two second connecting structures 20. The two first connecting structures 10 are symmetrically arranged, and the two second connecting structures 20 are symmetrically arranged. The first connecting structures 10 and the second connecting structures 20 located on the same side are spaced apart. This installation method improves the stability of the gas cylinder bracket 3 installation.

[0060] Specifically, the second connecting structure 20 includes a connecting body 21 and a fourth connecting part. The upper end of the connecting body 21 is provided with a plurality of fourth connecting parts spaced apart along the vehicle driving direction. When installing gas cylinders 4 of different diameters, the installation position of the corresponding gas cylinder bracket 3 is different. The appropriate fourth connecting part can be selected for installation according to the actual installation position of the gas cylinder bracket 3, so as to improve the flexibility of the second connecting structure 20. The combined use of the first connecting structure 10 and the second connecting structure 20 can improve the application range of the connecting component, thereby further improving the versatility of the connecting component.

[0061] Furthermore, the connecting body 21 has multiple sets of fourth connecting holes 22 spaced apart along the vehicle's driving direction, and the gas cylinder bracket 3 has a set of through holes. Each set of through holes can be matched with any set of fourth connecting holes 22. Fasteners are inserted through the matching through holes and fourth connecting holes 22 to connect the connecting body 21 and the gas cylinder bracket 3. Specifically, in this embodiment, the connecting body 21 is provided with two fourth connecting parts spaced apart along the vehicle's driving direction. Each fourth connecting part includes four fourth connecting holes 22, which are respectively arranged at the four corners of the rectangular structure. The gas cylinder bracket 3 is provided with four through holes, which are respectively arranged at the four corners of the rectangular structure. The four through holes can be connected one-to-one with one of the four sets of four fourth connecting holes 22. Four fasteners are provided, which are respectively arranged one-to-one with the four through holes and the four fourth connecting holes 22 to connect the gas cylinder bracket 3 to the connecting body 21. This arrangement allows the gas cylinder bracket 3 to be connected to different fourth connecting parts to adjust the installation position of the gas cylinder bracket 3, improve the positional flexibility of the gas cylinder bracket 3, and adapt to gas cylinders 4 with different installation requirements. The connection stability is also high.

[0062] Specifically, in this embodiment, the number of fourth connecting parts can be set according to actual use, and can be three, four or even more, which will not be elaborated here.

[0063] Specifically, in this embodiment, the connecting body 21 is provided with two sets of fourth pillars 221. Each set of fourth pillars 221 is arranged at the four corners of the rectangular structure. The four fourth connecting holes 22 are respectively opened on the four fourth pillars 221. The setting of the fourth pillars 221 can improve the structural strength at the fourth connecting holes 22, thereby improving the stability.

[0064] Furthermore, the second connecting structure 20 also includes fifth connecting parts. Several fifth connecting parts are disposed at the second end of the connecting body 21, and these fifth connecting parts are spaced apart along the vehicle height direction. Any one of the fifth connecting parts can connect the connecting body 21 to the frame 2. Specifically, in this embodiment, two fifth connecting parts are provided, spaced apart along the vehicle height direction. This arrangement allows adjustment of the height of the overlapping portion when the connecting body 21 and the frame 2 are connected, thereby adjusting the distance between the second support 23 and the frame 2, and thus adjusting the height of the gas cylinder bracket 3, thereby improving versatility.

[0065] Furthermore, the fifth connecting part consists of several fifth connecting holes 24 formed in the connecting body 21, and the several fifth connecting holes 24 are spaced apart along the vehicle's driving direction. Specifically, in this embodiment, the connecting body 21 is provided with a fifth column 241, four fifth columns 241 are spaced apart along the vehicle's driving direction to form a fifth column group, two fifth column groups are spaced apart along the vehicle's height direction, and each fifth column 241 is provided with the aforementioned fifth connecting hole 24. The frame 2 is provided with four spaced second connecting through holes, and fastening bolts pass through the second connecting through holes and the fifth connecting holes 24 in sequence and are threadedly connected to the nuts to connect the connecting body 21 to the frame 2. This arrangement allows for the selection of fifth connecting parts of different heights, thereby changing the height of the overlapping part between the connecting body 21 and the frame 2, and thus changing the height of the gas cylinder bracket 3, improving versatility and flexibility.

[0066] Specifically, in this embodiment, a reinforcing rib 31 is provided between any one of the fifth columns 241 and at least another fifth column 241, which can improve the structural strength of the connecting body 21 and ensure safe use.

[0067] Furthermore, the second connecting structure 20 also includes a second support portion 23, which protrudes from the connecting body 21 and is used to support the gas cylinder bracket 3. Specifically, in this embodiment, the second support portion 23 and the fourth connecting portion work together to improve the installation stability of the gas cylinder bracket 3.

[0068] Furthermore, in this embodiment, since the bottom of the gas cylinder bracket 3 is parallel to the ground, the height of the support surface of the second support part 23 from the ground is always the same as the height of the support surface of the first support part 112 from the ground, thereby ensuring the installation stability of the gas cylinder bracket 3.

[0069] like Figure 5As shown, this embodiment also provides a vehicle, which includes a frame 2, a gas cylinder 4 and a gas cylinder bracket 3, and also includes the aforementioned connecting component.
