Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of hydrogen monitoring, and specifically, to a vehicle. Background Art
[0002] During the operation of a vehicle with a hydrogen internal combustion engine, the hydrogen reaction in the internal combustion engine may not be sufficient. If unreacted hydrogen enters the exhaust system, it may seriously explode, resulting in casualties and vehicle damage.
[0003] In related technologies, in order to monitor whether there is hydrogen in the exhaust system, a hydrogen sensor is usually set. However, since the gas in the exhaust system is usually high-temperature gas, the temperature of the gas entering the hydrogen sensor is relatively high, so it is easy to cause damage to the hydrogen sensor and lead to monitoring failure. Summary of the Utility Model
[0004] The purpose of the present disclosure is to provide a vehicle that can cool the exhaust gas entering the hydrogen sensor in advance to avoid damage to the hydrogen sensor caused by too high exhaust gas temperature, thereby ensuring the good function of the hydrogen sensor and effective monitoring.
[0005] To achieve the above purpose, the present disclosure provides a vehicle, including a hydrogen internal combustion engine, a hydrogen storage device, a hydrogen sensor, a heat conduction pipe, and an exhaust pipe. The hydrogen storage device is communicated with the fuel inlet of the hydrogen internal combustion engine to supply hydrogen to the hydrogen internal combustion engine. The inlet of the exhaust pipe is communicated with the outlet of the supercharger of the hydrogen internal combustion engine to discharge the exhaust gas of the hydrogen internal combustion engine. The hydrogen sensor is used to detect the purity of the exhaust gas discharged from the exhaust pipe. The heat conduction pipe is used to cool the exhaust gas introduced into the hydrogen sensor. Wherein, one end of the heat conduction pipe is communicated with the hydrogen sensor, and the other end is communicated with the exhaust pipe.
[0006] Optionally, the heat conduction pipe is configured as a copper pipe.
[0007] Optionally, the vehicle further includes a vehicle frame and a fixing member. The heat conduction pipe is fixed on the fixing member, and the fixing member is fixed to the vehicle frame.
[0008] Optionally, the fixing member is configured as a fixing pipe, and at least part of the heat conduction pipe is wound around the fixing pipe in a circumferential direction, and the fixing pipe is fixed to the vehicle frame.
[0009] Optionally, the heat conduction pipe is wound around the fixing pipe for multiple turns, and there is a distance between two adjacent turns of the heat conduction pipe.
[0010] Optionally, the vehicle further includes a first mounting bracket, a clamp, and a first fastener. The first mounting bracket is configured in an L shape and includes a first plate segment and a second plate segment that are perpendicular to each other. A first mounting space is formed between the first plate segment and the second plate segment. The first plate segment is fixed to the vehicle frame, and the fixing member is disposed in the first mounting space and is locked and fixed to the second plate segment through the clamp and the first fastener.
[0011] Optionally, there are two first mounting brackets. The two first mounting brackets are arranged at intervals along the length direction of the fixing member and are respectively in one-to-one correspondence with the clamp and the first fastener.
[0012] Optionally, the vehicle further includes a second mounting bracket, a second fastener, and a vehicle frame. The second mounting bracket is configured in an L shape and includes a third plate segment and a fourth plate segment that are perpendicular to each other. A second mounting space is formed between the third plate segment and the fourth plate segment. The third plate segment is fixed to the vehicle frame, and the hydrogen sensor is disposed in the second mounting space and is locked and fixed to the fourth plate segment through the second fastener.
[0013] Optionally, the vehicle further includes a flexible connecting pipe and a rigid connecting pipe. Two ends of the heat conducting pipe are respectively communicated with the hydrogen sensor and one end of the rigid connecting pipe through the flexible connecting pipe, and the other end of the rigid connecting pipe is communicated with the exhaust pipe.
[0014] Optionally, the flexible connecting pipe is configured as a rubber hose, and / or the rigid connecting pipe is configured as a steel pipe.
[0015] Through the above technical solution, in the vehicle provided by the present disclosure, by providing the heat conducting pipe, the exhaust gas in the exhaust pipe first enters into the heat conducting pipe, and heat exchange is performed with the outside through the pipe wall of the heat conducting pipe. In this way, the exhaust gas entering the hydrogen sensor from the exhaust pipe can be pre-cooled to protect the hydrogen sensor in good condition and avoid directly introducing the exhaust gas with too high temperature in the exhaust pipe, which may cause damage to the hydrogen sensor and result in the failure of the hydrogen sensor to monitor.
[0016] Other features and advantages of the present disclosure will be described in detail in the subsequent specific implementation section. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0022] The following will describe in detail the specific embodiments of the present disclosure with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present disclosure, and are not intended to limit the present disclosure.
[0023] In the present disclosure, unless otherwise stated, the orientation terms such as "inside, outside" refer to "inside, outside" relative to the contour of the corresponding component itself. In addition, in the following description, when referring to the drawings, unless otherwise explained, the same reference numerals in different drawings represent the same or similar elements. The above definitions are only for explaining and illustrating the present disclosure, and should not be construed as a limitation to the present disclosure.
[0024] The present disclosure provides a vehicle. As shown in reference Figure 1 , the vehicle may include a hydrogen internal combustion engine (not shown in the figure), a hydrogen storage device (not shown in the figure), a hydrogen sensor 1, a heat conduction pipe 2, and an exhaust pipe 6. The hydrogen storage device is communicated with the fuel inlet of the hydrogen internal combustion engine to supply hydrogen to the hydrogen internal combustion engine. The inlet of the exhaust pipe 6 is communicated with the outlet of the supercharger of the hydrogen internal combustion engine to discharge the exhaust gas of the hydrogen internal combustion engine. The hydrogen sensor 1 is used to detect the purity of the exhaust gas discharged from the exhaust pipe. The heat conduction pipe 2 is used to cool the exhaust gas introduced into the hydrogen sensor 1. One end of the heat conduction pipe 2 is communicated with the hydrogen sensor 1, and the other end is used to be communicated with the exhaust pipe 6.
[0025] Through the above technical solution, in the hydrogen monitoring device provided by the present disclosure, by setting the heat conduction pipe 2, the exhaust gas in the exhaust pipe 6 first enters into the heat conduction pipe 2, and exchanges heat with the outside through the wall of the heat conduction pipe 2. In this way, the exhaust gas entering the hydrogen sensor 1 from the exhaust pipe 6 can be pre-cooled to protect the hydrogen sensor 1 in good condition and avoid directly introducing the exhaust gas with too high temperature in the exhaust pipe 6, resulting in damage to the hydrogen sensor 1 and causing the monitoring failure of the hydrogen sensor 1.
[0026] Among them, on the basis of ensuring reliable installation, in order to improve the detection accuracy as much as possible, the connection between the heat conduction tube 2 and the exhaust pipe 6 can be set upstream of the exhaust pipe 6. In this way, once hydrogen leakage occurs in the exhaust pipe 6, it will be immediately detected by the hydrogen sensor 1. Thus, the gas purity in the exhaust pipe 6 can be monitored to ensure safety and avoid safety accidents caused by hydrogen leakage in the exhaust pipe 6.
[0027] In the exemplary embodiment provided by the present disclosure, the heat conduction tube 2 can be constructed in any suitable structure, and the present disclosure does not limit this. Optionally, considering the heat dissipation performance and manufacturing cost of the heat conduction tube 2 comprehensively, the heat conduction tube 2 can be constructed as a copper tube.
[0028] In the exemplary embodiment provided by the present disclosure, referring to Figure 1 as shown in, the hydrogen monitoring device may further include a vehicle frame 7 and a fixing member 3. The heat conduction tube 2 is fixed on the fixing member 3, and the fixing member 3 is fixed to the vehicle frame 7. Through such a setting, the installation position of the heat conduction tube 2 can be fixed, and the heat conduction tube 2 can be prevented from deforming due to external forces during use, affecting the normal flow of the gas inside the heat conduction tube 2.
[0029] In the exemplary embodiment provided by the present disclosure, the fixing member 3 can be constructed in any suitable manner, such as a fixing tube 31, a fixing bracket, etc., and can be flexibly set according to the actual situation, and the present disclosure does not limit this. Optionally, referring to Figure 1 as shown in, when the fixing member 3 is constructed as a fixing tube 31, at least part of the heat conduction tube 2 can be wound around the fixing tube 31 in the circumferential direction, and the fixing tube 31 can be fixed to the vehicle frame 7 of the vehicle. Through such a setting, on the one hand, the heat conduction tube 2 can be reliably fixed to prevent the heat conduction tube 2 from deforming due to external forces during use, and on the other hand, the total length dimension of the heat conduction tube 2 can be increased by winding, so as to increase the heat dissipation area of the heat conduction tube 2 and improve the heat dissipation effect of the heat conduction tube 2. Among them, the fixing tube 31 can be a steel tube.
[0030] In the exemplary embodiment provided by the present disclosure, in order to further improve the heat dissipation effect of the heat conduction tube 2, while extending the total length of the heat conduction tube 2, sufficient heat dissipation gaps can be reserved between adjacent heat conduction tubes 2. Specifically, referring to Figure 1 as shown in, the heat conduction tube 2 can be set to be wound around the fixing tube 31 for multiple turns, and there is a spacing between adjacent two turns of the heat conduction tube 2. Among them, the total number of turns of the heat conduction tube 2 wound around the fixing tube 31 and the spacing between adjacent two turns of the heat conduction tube 2 can be flexibly selected according to the actual situation, and the present disclosure does not limit this.
[0031] In the exemplary embodiment provided by the present disclosure, referring to Figure 2As shown in the figure, the vehicle further includes a first mounting bracket 8, a clamp 9, and a first fastener 10. The first mounting bracket 8 is configured in an L shape and includes a first plate segment 81 and a second plate segment 82 that are perpendicular to each other. A first mounting space 11 is formed between the first plate segment 81 and the second plate segment 82. The first plate segment 81 is fixed to the vehicle frame 7. The fixing member 3 is disposed in the first mounting space 11 and is locked and fixed to the second plate segment 82 through the clamp 9 and the first fastener 10. Through such an arrangement, not only can the fixing member 3 be reliably fixed, but also the interference of the installation of the fixing member 3 to other surrounding components can be minimized as much as possible. Among them, the first fastener 10 can be a bolt and nut.
[0032] In the exemplary embodiment provided by the present disclosure, with reference to Figure 1 and Figure 2 As shown in the figure, in order to further improve the fixing effect of the first mounting bracket 8 on the fixing member 3, it can be provided that the first mounting bracket 8 includes two. The two first mounting brackets 8 can be arranged at intervals along the length direction of the fixing member 3 and respectively correspond to the clamp 9 and the first fastener 10 one by one.
[0033] In the exemplary embodiment provided by the present disclosure, with reference to Figure 2 As shown in the figure, the vehicle may further include a second mounting bracket 12, a second fastener 13, and a vehicle frame 7. The second mounting bracket 12 is configured in an L shape and includes a third plate segment 121 and a fourth plate segment 122 that are perpendicular to each other. A second mounting space 14 is formed between the third plate segment 121 and the fourth plate segment 122. The third plate segment 121 is fixed to the vehicle frame 7. The hydrogen sensor 1 is disposed in the second mounting space 14 and is locked and fixed to the fourth plate segment 122 through the second fastener 13. Through such an arrangement, on the one hand, the hydrogen sensor 1 can be reliably fixed, and on the other hand, the hydrogen sensor 1 disposed in the second mounting space 14 can be protected by the third plate segment 121 and the fourth plate segment 122 in the L-shaped second mounting bracket 12, avoiding interference to the hydrogen sensor 1 caused by other components on the side of the fourth plate segment 122 away from the hydrogen sensor 1. Among them, the second fastener 13 can be a bolt and nut.
[0034] In the exemplary embodiment provided by the present disclosure, with reference to Figure 1 As shown in the figure, the vehicle may further include a flexible connecting pipe 4 and a rigid connecting pipe 5. Two ends of the heat conduction pipe 2 are respectively communicated with the hydrogen sensor 1 and one end of the rigid connecting pipe 5 through the flexible connecting pipe 4, and the other end of the rigid connecting pipe 5 is communicated with the exhaust pipe 6. Through such an arrangement, on the one hand, it can facilitate the docking operation of the corresponding interfaces when the heat conduction pipe 2 is connected to the hydrogen sensor 1 and the exhaust pipe 6, and on the other hand, it can also ensure the reliability of the connection between these pipes, avoiding the occurrence of gas leakage due to unreliable connection.
[0035] Among them, the flexible connecting pipe 4 and the rigid connecting pipe 5 can be constructed in any suitable manner, and the present disclosure does not limit this. Exemplarily, considering the manufacturing cost and use performance comprehensively, there are three possible implementation manners for the flexible connecting pipe 4 and the rigid connecting pipe 5:
[0036] In the first possible implementation manner, the flexible connecting pipe 4 can be constructed as a rubber hose.
[0037] In the second possible implementation manner, the rigid connecting pipe 5 can be constructed as a steel pipe.
[0038] In the third possible implementation manner, the flexible connecting pipe 4 can be constructed as a rubber hose, and the rigid connecting pipe 5 can be constructed as a steel pipe.
[0039] The following describes the usage principle of the vehicle of the present disclosure:
[0040] When the vehicle of the present disclosure is in use, the hydrogen storage device is connected to the fuel inlet of the hydrogen internal combustion engine to supply hydrogen to the hydrogen internal combustion engine. The inlet of the exhaust pipe 6 is connected to the outlet of the supercharger of the hydrogen internal combustion engine to discharge the exhaust gas of the hydrogen internal combustion engine. The hydrogen sensor 1 is used to detect the purity of the exhaust gas discharged from the exhaust pipe. The heat conduction pipe 2 is used to cool the exhaust gas introduced into the hydrogen sensor 1. Among them, the exhaust gas in the exhaust pipe 6 is introduced into the heat conduction pipe 2 through the flexible connecting pipe 4 provided at one end of the rigid connecting pipe 5 and the heat conduction pipe 2. After that, these exhaust gases exchange heat with the outside through the pipe wall of the heat conduction pipe 2, so that these exhaust gases can be cooled. The cooled exhaust gas is then introduced into the hydrogen sensor 1 through the flexible connecting pipe 4 provided at the other end of the heat conduction pipe 2. In this way, the hydrogen sensor 1 can receive the exhaust gas to be detected that meets the monitoring requirements and will not damage the internal components of the hydrogen sensor 1 due to excessive temperature. In this way, the hydrogen sensor 1 can monitor the exhaust gas situation in the exhaust pipe 6 in real time and avoid the failure of the hydrogen sensor 1 due to the excessive temperature of the exhaust gas to be detected.

[0042] In addition, it should be noted that, among the various specific technical features described in the above specific embodiments, they can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present disclosure does not separately describe various possible combination manners.
[0043] In addition, any combination can be made among various different embodiments of the present disclosure, as long as it does not violate the idea of the present disclosure, and it should also be regarded as the content disclosed by the present disclosure.
