Description

Technical Field

[0001] The present invention relates to the technical field of hydrogen supply systems, and in particular to an infrared emission module applied to hydrogen supply systems. Background Art

[0002] With the development of the hydrogen energy industry, new energy vehicles represented by hydrogen fuel vehicles will be another global-level golden age of industry development after lithium battery vehicles. At present, China mainly uses 35MPa on-board hydrogen storage, which is mainly used in the field of commercial vehicles. 35MPa hydrogen energy vehicles mainly adopt the form of "blind refueling", that is, there is no feedback from the vehicle during the hydrogenation process. The hydrogenation machine controls the hydrogenation rate based on experience and realizes hydrogenation by slow hydrogenation. This method takes a long time to refuel, and the waiting time for buses or heavy trucks with large hydrogen storage capacity is too long, which affects the customer experience. At the same time, under the same volume, the hydrogen storage capacity under 35MPa pressure is small and cannot meet the requirements of long-distance transportation. Therefore, in the process of continuous accumulation of technology, China began to develop 70MPa on-board hydrogen storage technology. Compared with 35MPa, 70MPa hydrogen energy vehicles have high storage pressure and fast hydrogenation speed, so the temperature rises faster during the hydrogenation process. If the temperature rise cannot be controlled, it will quickly reach the operating temperature limit of 85℃ of the hydrogen storage system. During the hydrogenation process, the gas will be pre-cooled to -40°C, and the pre-cooled hydrogen will reach the hydrogen storage cylinder through the hydrogenation gun. However, due to the large pressure difference between the hydrogen bottle and the hydrogenation machine and the fast gas flow rate, the temperature rises quickly. If it cannot be detected, it will affect the life of the hydrogen storage system of the hydrogen energy vehicle and directly damage the function of each valve. Infrared communication modules are used in the 70MPa hydrogen energy vehicle hydrogen storage system. This module uses an infrared transmitter to feed back the pressure and temperature signals of the hydrogen storage system to the hydrogenation machine, and the hydrogenation machine controls the flow rate according to the obtained data. In this way, it can not only meet the rapid hydrogenation process, but also protect the components of the hydrogen storage system.

[0003] The traditional infrared emission module is in the shape of a ring, and the hydrogenation port is directly fixed to the hydrogenation panel through the fixing bolts on the hydrogenation port. This form has high requirements on the length of the hydrogenation port and the thickness of the hydrogenation panel, which exceeds the current minimum length requirement of GB / T26779. Although this method meets the requirements of the national standard, for passenger cars, due to the small space, this form of hydrogenation port may directly touch the hydrogenation cover of the vehicle, which brings great difficulties to the redevelopment of the vehicle (because there are specific requirements for the length of the hydrogenation port extending into the hydrogenation gun). On the other hand, in the process of hydrogenation port development, each supplier refers to the relevant requirements of ISO, SAE, and GB, and will not develop a hydrogenation port suitable for circular infrared emission modules. This form will make it difficult to match the same infrared emission module with hydrogenation ports of different brands in the future, and it is not suitable for market development needs. Summary of the invention

[0004] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide an infrared transmitting module for use in a hydrogen supply system, which aims to ensure that the different shapes and sizes of the hydrogenation port will not affect the fixation of the infrared transmitting module through the new infrared transmitting module, and the hydrogenation port does not need to increase the overall shape length due to the fixation of the infrared transmitting module. The half-moon-shaped structure has an integrated infrared transmitting point that coincides with the receiving point integrated in the hydrogenation gun, and data can be transmitted in real time during the hydrogenation process to achieve rapid hydrogenation.

Data can be transmitted in real time during the hydrogenation process to achieve rapid hydrogenation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0025] See also Figure 1-3 It should be noted that the illustrations provided in this embodiment are only used to illustrate the basic concept of the present invention in a schematic manner, and the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0026] like Figure 1-Figure 3As shown, an infrared transmitting module 12 applied to a hydrogen supply system of the present invention comprises: a hydrogenation panel 11, an infrared transmitting module 12, a connecting end of the infrared transmitting module 12, and a hydrogenation port 14; the infrared transmitting module 12 and the hydrogenation port 14 are fixed on the hydrogenation panel 11; the infrared transmitting module 12 is fixed on the hydrogenation panel 11 through its corresponding connecting end; the infrared transmitting module 12 is a half-moon structure; the transmitting line of the infrared transmitting module 12 is arranged in the hydrogenation panel 11, and the transmitting line is connected to the inside of the hydrogen system through the hydrogenation panel 11; the infrared transmitting module 12 has an integrated infrared transmitting point, which coincides with the receiving point integrated in the hydrogenation gun.

[0027] It should be noted that the other end of the infrared transmitting module is connected to the control module (this module is the control module of the hydrogen supply system, which can be implemented by the CPU used by the notification module in the prior art, and the embodiment of the present invention does not improve it), and the data collected by the hydrogen system (such as high pressure, temperature in the bottle, etc.) is transmitted to the infrared control module through the connecting line, and finally fed back to the hydrogen filling machine through the infrared transmitting module.

[0028] In one implementation of the present invention, the infrared transmitting module 12 includes a first connecting end 131 and a second connecting end 132; the first connecting end 131 is arranged at one end of the half-moon-shaped structure, and the second connecting end 132 is arranged at the other end of the half-moon-shaped structure; the first connecting end 131 and the second connecting end 132 are connected to the hydrogenation panel 11 by bolts.

[0029] like Figure 1 and Figure 2 As shown, the infrared emission module 12 is fixed to the hydrogenation panel 11 by bolts. In this way, the different shapes and sizes of the hydrogenation port 14 will not affect the fixation of the infrared emission module 12, and the hydrogenation port 14 does not need to increase the overall shape length due to the fixation of the infrared emission module 12.

[0030] The infrared transmitting module 12 has a half-moon-shaped structure and an integrated infrared transmitting point, which coincides with the receiving point integrated in the hydrogenation gun. During the hydrogenation process, data can be transmitted in real time to achieve rapid hydrogenation.

[0031] In one implementation, Figure 2 and Figure 3 As shown, the infrared emission module 12 is provided with a plurality of bosses 121. The extension direction of the plurality of bosses 121 is consistent with the extension direction of the hydrogenation port 14, and the size of the plurality of bosses 121 decreases along the extension direction. Figure 3 The fixing structure 122 can further fix the infrared emission module 12 by cooperating with the through hole in the hydrogenation panel 11.

[0032] Since the infrared emission module 12 adopts a half-moon structure, the overall emission points are reduced, material costs are saved, and normal use is not affected. When the infrared emission module 12 is installed, different bosses 121 are separately provided, which can not only meet the installation requirements, but also make the infrared emission module 12 and the hydrogenation panel 11 completely fit together to achieve a stable fixation.

[0033] The original structure of the infrared emission line needs to open a hole on the hydrogenation panel 11. Because the line itself is soft and not firmly fixed, the surface of the emission line will be worn during the vehicle driving. The infrared emission module 12 of the new structure is directly inside the hydrogenation panel 11, that is, there is no need to set up a separate infrared emission line hole, and the emission line can be connected to the inside of the hydrogen system.

[0034] In one implementation, the hydrogenation panel 11 is provided with a third connection end 111 and a fourth connection end 112;

[0035] The third connection end 111 and the fourth connection end 112 are used to fix the hydrogenation panel 11 by means of bolts and nuts.

[0036] In one implementation, the main structure of the hydrogenation panel 11 is a square structure.

[0037] By using the infrared transmitting module 12 applied to the hydrogen supply system of the present invention, different shapes and sizes of the hydrogen filling port 14 will not affect the fixation of the infrared transmitting module 12 through the new infrared transmitting module 12, and the hydrogen filling port 14 does not need to increase the overall shape length due to the fixation of the infrared transmitting module 12. The half-moon-shaped structure has an integrated infrared transmitting point, which coincides with the receiving point integrated with the hydrogen filling gun, and can transmit data in real time during the hydrogenation process to achieve rapid hydrogenation.

[0038] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
