[0001] The utility model relates to the technical field of automotive parts, in particular to a hydrogen filling port installation structure. At the same time, the utility model also relates to a vehicle provided with the above hydrogen filling port installation structure. Background Art

[0002] With the progress of society, the popularization and application of hydrogen fuel cell vehicles have developed rapidly.

[0003] Currently, for existing hydrogen energy vehicles, after the fuel cell and the hydrogen storage system are docked, an airtightness test needs to be carried out. Generally, after the fuel cell and the hydrogen storage system are installed on the chassis, the airtightness test is carried out. After the airtightness test is completed, the body is docked and installed, and finally the whole vehicle assembly is completed.

[0004] However, due to the influence of the assembly process of some vehicle models, the fuel cell and the hydrogen storage system cannot be first installed on the chassis for airtightness testing and then docked with the body. Instead, the airtightness test of the entire fuel cell and hydrogen storage system can only be carried out after the whole vehicle assembly is completed. Therefore, after the whole vehicle assembly, the hydrogen filling port connection point has been blocked by the splash guard and the tire, which is not convenient for detecting whether hydrogen leaks.

[0050] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0051] Embodiment 1

[0052] This embodiment relates to a hydrogen filling port installation structure, which can solve the problem that the airtightness of the connection point of the hydrogen filling port cannot be detected after the vehicle is assembled, thus facilitating the airtightness detection without affecting the vehicle assembly. In terms of the overall structure, as shown in Figures 1 to 8 the hydrogen filling port installation structure of this embodiment includes a shielding member 1 and a hydrogen filling port mounting plate 2.

[0053] Among them, the shielding member 1 is used to block the installation hole 41 on the vehicle body 4, and a first opening 11 is provided on the shielding member 1. At the same time, the hydrogen filling port mounting plate 2 is used to install the hydrogen filling port 3, and a second opening 21 is provided on the hydrogen filling port mounting plate 2.

[0054] The shielding member 1 and the hydrogen filling port mounting plate 2 are detachably connected. The hydrogen filling port 3 is connected to the hydrogen filling pipeline 42 on the vehicle body 4. When the hydrogen filling port mounting plate 2 is not connected to the shielding member 1, the hydrogen filling port mounting plate 2 can be in an open position where the first opening 11 and the second opening 21 are communicated. After the hydrogen filling port mounting plate 2 rotates around the center of the installation hole 41, the shielding member 1 and the hydrogen filling port mounting plate 2 are connected, and the hydrogen filling port mounting plate 2 can be in a closed position where the first opening 11 is blocked.

[0055] At this time, with the above settings, by providing the first opening 11 on the shielding member 1, the second opening 21 on the hydrogen filling port mounting plate 2, and making the shielding member 1 and the hydrogen filling port mounting plate 2 detachably connected, when the hydrogen filling port mounting plate 2 is not connected to the shielding member 1, the hydrogen leakage detection rod 7 can pass through the communication position of the first opening 11 and the second opening 21 to detect whether there is hydrogen leakage at the connection part between the hydrogen filling port 3 and the hydrogen filling pipeline 42.

[0056] After the detection is completed, by rotating the hydrogen filling port mounting plate 2 and connecting the hydrogen filling port mounting plate 2 to the shielding member 1, the hydrogen filling port mounting plate 2 can block the first opening 11, avoiding the external leakage of the connection part between the hydrogen filling port mounting plate 2 and the shielding member 1, thus ensuring the beauty of the installation position of the hydrogen filling port 3, and further facilitating the airtightness detection without affecting the vehicle assembly.

[0057] Moreover, this hydrogen filling port installation structure is installed on the vehicle, which can increase the diversity of the hydrogen storage system assembly process. The vehicle can be transported to other testing institutions for testing after the vehicle assembly is completed, preventing the reconstruction of the hydrogen airtight detection equipment on the production line, reducing the detection cost of the vehicle, and improving the utilization rate of the existing detection equipment.

[0058] Here, it should be noted that the edge of the shielding member 1 of this embodiment is made of plastic material, and the central part is made of rubber material. Thus, it is convenient to install on the vehicle body 4 and has a good shock absorption effect, which can prevent abnormal noises from occurring at the connection part between the hydrogen filling port mounting plate 2 and the shielding member 1.

[0059] Based on the above design concept, the hydrogen filling port mounting structure of this embodiment, as an exemplary structure, as shown in Figure 2 shown, a positioning structure 51 is provided between the hydrogen filling port mounting plate 2 and the shielding member 1, and the positioning structure 51 is used to keep the hydrogen filling port mounting plate 2 in the open position.

[0060] Here, a positioning structure 51 is provided between the hydrogen filling port mounting plate 2 and the shielding member 1. When performing the airtightness detection of hydrogen leakage, the hydrogen filling port mounting plate 2 can be kept in the open position through the positioning structure 51 to prevent the hydrogen filling port mounting plate 2 from rotating, thereby facilitating the airtightness detection of hydrogen leakage.

[0061] Specifically, in this embodiment, as a preferred implementation form, continue to refer to Figure 2 shown in, the positioning structure 51 includes a positioning hole 511 provided on the shielding member 1 and a positioning pin 512 provided on the hydrogen filling port mounting plate 2. The positioning pin 512 is specifically provided on the side of the hydrogen filling port mounting plate 2 facing the shielding member 1. The positioning pin 512 is inserted into the positioning hole 511, and can keep the hydrogen filling port mounting plate 2 in the open position.

[0062] The advantage of such a setting is that the positioning structure 51 is set as the positioning hole 511 and the positioning pin 512, with a simple structure and convenient processing, and has a good positioning effect. In the specific structure, both the positioning hole 511 and the positioning pin 512 can be set to multiple, and the multiple positioning holes 511 and positioning pins 512 are both distributed at intervals around the following through hole 22.

[0063] It should be noted that the number of the positioning holes 511 can be set to six, and the number of the positioning pins 512 can be set to three. Of course, in addition to setting the positioning holes 511 and the positioning pins 512 to the above numbers, corresponding designs and adjustments can also be made according to actual positioning requirements.

[0064] During specific implementation, rotate the hydrogen filling port mounting plate 2 to make the first opening 11 and the second opening 21 in a communicating state. At this time, the three positioning pins 512 can be aligned with three of the positioning holes 511, and each positioning pin 512 is inserted into the corresponding positioning hole 511, which can pre-fix the hydrogen filling port mounting plate 2, so that the hydrogen filling port mounting plate 2 is kept in the open position, facilitating the airtightness detection.

[0065] After the airtightness detection is completed, pull out the hydrogen filling port mounting plate 2, then rotate the hydrogen filling port mounting plate 2 to the closed position (that is, the hydrogen filling port mounting plate 2 covers the first opening 11), insert each positioning pin 512 into the other three positioning holes 511, which does not affect the screw connection between the hydrogen filling port mounting plate 2 and the shielding member 1, and can also pre-fix the hydrogen filling port mounting plate 2, facilitating the connection of the hydrogen filling port mounting plate 2 and the shielding member 1 together using the screw connection structure 52.

[0066] In addition, in this embodiment, as a preferred implementation form, as Figure 2 and Figure 4 shown in, the hydrogen filling port mounting plate 2 and the shielding member 1 are connected by a plurality of screwed structures 52, and the plurality of screwed structures 52 are distributed at intervals around the center of the mounting hole 41. With this setting, the hydrogen filling port mounting plate 2 and the shielding member 1 are connected by the screwed structures 52, and the screwed structures 52 can adopt existing standard parts, with relatively low costs.

[0067] Specifically, the screwed structure 52 includes bolt through holes correspondingly provided on the hydrogen port mounting plate 2 and the shielding member 1, bolts inserted through the corresponding bolt through holes, and nuts screwed with the bolts.

[0068] It is worth mentioning that the number of the screwed structures 52 in this embodiment can be set to three. Of course, in addition to being set to three, it can also be designed and adjusted according to actual fastening requirements. For example, it can be set to four or five, etc.

[0069] Furthermore, in this embodiment, as another preferred implementation form, as Figure 8 shown in, the hydrogen filling port mounting plate 2 and the shielding member 1 are connected by a plurality of snap fasteners 53, and the plurality of snap fasteners 53 are distributed at intervals around the center of the mounting hole 41. Here, the hydrogen filling port mounting plate 2 and the shielding member 1 are connected by the snap fasteners 53, and the snap fasteners 53 can adopt existing standard parts, with relatively low costs.

[0070] During specific implementation, the number of the snap fasteners 53 can be set to three. Of course, in addition to being set to three, it can also be designed and adjusted according to actual fixing requirements. For example, it can be set to four or five, etc.

[0071] Meanwhile, in the specific structure, the snap fastener 53 includes a male snap 531 and a female snap 532. The shielding member 1 is provided with a first opening 12, and the hydrogen filling port mounting plate 2 is provided with a second opening 24 corresponding to the first opening 12. The female snap 532 is inserted through the first opening 12, and the male snap 531 passes through the second opening 24 and is snap-connected to the female snap 532, enabling the hydrogen filling port mounting plate 2 to be connected to the shielding member 1.

[0072] In addition, as a preferred implementation form, in this embodiment, referring to Figure 3 shown in, an infrared emitter 6 is provided on the hydrogen filling port mounting plate 2. Installing the infrared emitter 6 on the hydrogen filling port mounting plate 2 facilitates detecting whether the hydrogen filling gun is inserted into the hydrogen filling port 3.

[0073] It is worth mentioning that the infrared emitter 6 can adopt the infrared emitter 6 products in the prior art. In specific implementation, the infrared emitter 6 emits infrared rays. When the hydrogenation gun is detected, the signal is fed back. At this time, the hydrogenation gun has been docked with the hydrogenation port 3, so that hydrogenation can be carried out.

[0074] Furthermore, in this embodiment, as a preferred implementation form, still as Figure 3 shown in, a through hole 22 is provided on the hydrogenation port mounting plate 2, and the hydrogenation port 3 is inserted through the through hole 22 and fixed to the hydrogenation port mounting plate 2 through a fastening structure 23.

[0075] Here, by providing the through hole 22 on the hydrogenation port mounting plate 2, the hydrogenation port 3 is inserted into the through hole 22 and fixed to the hydrogenation port mounting plate 2 through the fastening structure 23, which facilitates the installation of the hydrogenation port 3 and can preferably ensure the stability of the installation of the hydrogenation port 3.

[0076] In specific implementation, the hydrogenation port 3 is connected to the hydrogenation pipeline 42 on the vehicle body 4. After the connection is completed, the connection part between the hydrogenation port 3 and the hydrogenation pipeline 42 is detected by the hydrogen leakage detection rod 7. After the detection is completed, the hydrogenation port mounting plate 2 is rotated by a certain angle to block the first opening 11. Secondly, the hydrogenation port 3 is fixed to the hydrogenation port mounting plate 2 through the fastening structure 23. Subsequently, the hydrogenation port mounting plate 2 is fixed to the shielding member 1 through three screwing structures 52.

[0077] And, in this embodiment, as a preferred implementation form, as Figure 4 and Figure 5 shown in, the fastening structure 23 includes a first nut 231 and a second nut 232. The first nut 231 and the second nut 232 are respectively screwed to the housing of the hydrogenation port 3, and the first nut 231 and the second nut 232 are respectively arranged on both sides of the hydrogenation port mounting plate 2. With this setting, the fastening structure 23 includes the first nut 231 and the second nut 232, and existing standard parts can be used, with relatively low cost. When the first nut 231 and the second nut 232 are not tightened, it is convenient to connect the hydrogenation port 3 to the hydrogenation pipeline 42. After the first nut 231 and the second nut 232 are tightened, the hydrogenation port 3 can be firmly fixed to the hydrogenation port mounting plate 2.

[0078] In the preferred implementation manner, still referring to Figure 5 shown in, the fastening structure 23 further includes a limit nut 235. The limit nut 235 is screwed to the housing of the hydrogenation port 3, and the limit nut 235 is arranged away from the hydrogenation port mounting plate 2 relative to the second nut 232, which is beneficial to improving the reliability of the fixation of the hydrogenation port 3 on the hydrogenation port mounting plate 2. Secondly, in this embodiment, as a preferred implementation form, still referring to Figure 4 and Figure 5As shown in the figure, the fastening structure 23 further includes a first limiting block 233 and a second limiting block 234. The first limiting block 233 and the second limiting block 234 are respectively sleeved on the housing of the hydrogen filling port 3 through their own through holes.

[0079] Meanwhile, the first limiting block 233 and the second limiting block 234 are respectively located on both sides of the hydrogen filling port mounting plate 2, and the first limiting block 233 is clamped between the first nut 231 and the hydrogen filling port mounting plate 2, and the second limiting block 234 is clamped between the second nut 232 and the hydrogen filling port mounting plate 2. It can be understood that the fastening structure 23 includes the first limiting block 233 and the second limiting block 234, which is beneficial to improving the stability and reliability of the installation of the hydrogen filling port 3 on the hydrogen filling port mounting plate 2.

[0080] It is still worth mentioning that the first limiting block 233 and the second limiting block 234 in this embodiment can both adopt the limiting products well-known to those skilled in the art, such as gaskets, etc.

[0081] In addition, in this embodiment, as a preferred implementation form, referring to Figure 6 As shown in the figure, the housing of the hydrogen filling port 3 includes a first housing 31 and a second housing 32. The first housing 31 has an extension section 311 extending outside the hydrogen filling port mounting plate 2. And, the second housing 32 is inserted and connected to the extension section 311, and the second housing 32 and the extension section 311 can rotate relative to each other. A sealing portion 33 for sealing the gap between the two is provided between the second housing 32 and the first housing 31.

[0082] Here, it can be understood that the housing of the hydrogen filling port 3 is composed of the first housing 31 and the second housing 32, and the sealing portion 33 is provided between the two to facilitate sealing the gap at the connection part of the first housing 31 and the second housing 32, and enable the second housing 32 to rotate relative to the extension section 311. When the hydrogen filling gun is inserted into the hydrogen filling port 3, it is convenient for the hydrogen filling gun to be smoothly inserted into the hydrogen filling port 3.

[0083] For example Figure 6 As shown in the figure, the first housing 31 is provided with threads for screwingly connecting with the aforementioned first nut 231, second nut 232 and limiting nut 235, and the extension section 311 is a part of the first housing 31. After the hydrogen filling port 3 is fixed on the hydrogen filling port mounting plate 2, the extension section 311 is exposed on the side of the hydrogen filling port mounting plate 2 facing away from the vehicle.

[0084] It still needs to be explained that the sealing portion 33 in this embodiment can adopt the sealing products well-known to those skilled in the art, such as sealing rings, etc.

[0085] At the same time, as Figure 7As shown in the figure, in this embodiment, in order to prevent the second housing 32 from slipping off the extension section 311, an anti-slip protrusion 321 is provided on the outer wall of the second housing 32, and a groove 312 adapted to the anti-slip protrusion 321 is formed on the inner wall of the first housing 31. The groove 312 is arranged to extend along the circumferential direction of the housing. During assembly, the anti-slip protrusion 321 on the second housing 32 is snapped into the groove 312 to complete the assembly of the second housing 32 and the first housing 31.

[0086] When the hydrogen filling port installation structure of this embodiment is in use, after connecting the hydrogen filling port 3 to the hydrogen filling pipeline 42, the hydrogen filling port 3 is fixed on the hydrogen filling port mounting plate 2 by tightening the first nut 231 and the second nut 232. At this time, the hydrogen filling port mounting plate 2 is rotated to communicate the first opening 11 and the second opening 21, and the connection part between the hydrogen filling port 3 and the hydrogen filling pipeline 42 is detected by the hydrogen leakage detection rod 7.

[0087] After the detection is completed, the hydrogen filling port mounting plate 2 is rotated again to block the first opening 11, and the hydrogen filling port mounting plate 2 is fixed on the shielding member 1 through the screw connection structure 52 to complete the assembly of the whole vehicle.

[0088] Embodiment Two

[0089] This embodiment relates to a vehicle, and the hydrogen filling port 3 of the vehicle is installed on the vehicle body 4 through the hydrogen filling port installation structure in Embodiment One.

[0090] For the vehicle of this embodiment, by setting the hydrogen filling port installation structure in Embodiment One, the aesthetics of the installation position of the hydrogen filling port 3 can be guaranteed, and it is beneficial to perform airtightness detection while not affecting the assembly of the whole vehicle. At the same time, the diversity of the hydrogen storage system assembly process can be increased. The whole vehicle can be transported to other testing institutions for testing after the assembly of the whole vehicle is completed, preventing the reconstruction of the hydrogen airtight detection equipment on the production line body, reducing the detection cost of the whole vehicle, and improving the utilization rate of the existing detection equipment.

[0091] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
