[0029] Reference below Figure 1-Figure 3 A hydrogen bottle assembly 100 according to an embodiment of the utility model is described. By setting a limiting portion 12 at the bottle tail of the hydrogen bottle 1, and connecting the limiting portion 12 to the vehicle body through the bottle tail bracket assembly 3, the hydrogen bottle 1 is connected to the vehicle body from the bottle body of the hydrogen bottle 1 through the bottle body strap 2, which can improve the connection reliability and connection stability between the hydrogen bottle 1 and the vehicle body, prevent the hydrogen bottle 1 from axially dislodging and being damaged when the vehicle collides, and can make full use of the space on the vehicle, making the layout of the entire vehicle more reasonable.

[0030] like Figure 1-Figure 3 As shown, a hydrogen bottle assembly 100 according to an embodiment of the utility model includes: a hydrogen bottle 1, a bottle body strap 2 and a bottle tail bracket assembly 3.

[0031] The hydrogen bottle 1 has a bottle valve 11 at its bottle head and a limiting portion 12 at its bottle tail.

[0032] Specifically, the hydrogen bottle 1 is used to store hydrogen. A bottle valve 11 is provided at the bottle head of the hydrogen bottle 1. The bottle valve 11 is used to open or close the bottle mouth of the hydrogen bottle 1. A limiting portion 12 is provided at the bottle tail of the hydrogen bottle 1. The limiting portion 12 is used to cooperate with other components in the hydrogen bottle assembly 100 to limit the installation of the hydrogen bottle 1.

[0033] The bottle body strap 2 is suitable for being connected to the vehicle body, and the bottle body strap 2 is sleeved outside the bottle body of the hydrogen bottle 1 .

[0034] Specifically, a bottle body strap 2 is also provided on the bottle body of the hydrogen bottle 1, and the bottle body strap 2 is used to fix the hydrogen bottle 1 from the bottle body. By putting the bottle body strap 2 on the outside of the bottle body of the hydrogen bottle 1, the matching connection between the hydrogen bottle 1 and the bottle body strap 2 can be achieved, and by connecting the bottle body strap 2 to the vehicle body, the hydrogen bottle 1 can be connected to the vehicle body through the bottle body strap 2, thereby realizing the installation and fixation of the hydrogen bottle 1 on the vehicle.

[0035] The bottle tail bracket assembly 3 includes a connecting bracket 31 and a fixing bracket 32. The connecting bracket 31 is suitable for connecting to the vehicle body. The fixing bracket 32 ​​is detachably connected to the connecting bracket 31. The fixing bracket 32 ​​is sleeved outside the limiting portion 12 and cooperates with the limiting portion 12 in radial and axial limiting manners.

[0036] Specifically, a bottle tail bracket assembly 3 is also provided at the bottle tail of the hydrogen bottle 1, and the bottle tail bracket assembly 3 is used to fix the hydrogen bottle 1 from the bottle tail, so that the bottle tail bracket assembly 3 includes a connecting bracket 31 and a fixing bracket 32, and the fixing bracket 32 ​​is sleeved outside the limiting portion 12, so that the fixing bracket 32 ​​can cooperate with the limiting portion 12, so as to realize the connection between the bottle tail bracket assembly 3 and the hydrogen bottle 1 through the cooperation between the fixing bracket 32 ​​and the limiting portion 12, and make the fixing bracket 32 ​​cooperate with the limiting portion 12 along the radial and axial limiting of the hydrogen bottle 1, so that the hydrogen bottle 1 can be radially and axially limited by the cooperation between the fixing bracket 32 ​​and the limiting portion 12, so as to avoid the hydrogen bottle 1 from falling out and being damaged when the vehicle collides.

[0037] At the same time, by connecting the connecting bracket 31 to the vehicle body, the bottle tail bracket assembly 3 can be connected to the vehicle body through the connecting bracket 31, and the connecting bracket 31 and the fixed bracket 32 ​​are detachably connected, so that the connecting bracket 31 and the fixed bracket 32 ​​can be easily connected or separated. When the connecting bracket 31 and the fixed bracket 32 ​​are connected, the hydrogen bottle 1 can be connected to the vehicle body through the connecting bracket 31 and the fixed bracket 32. When the connecting bracket 31 and the fixed bracket 32 ​​are separated, the separation between the hydrogen bottle 1 and the vehicle body can be achieved, so as to facilitate the maintenance or replacement of the hydrogen bottle 1.

[0038] Furthermore, when the hydrogen bottle 1 is installed, the bottle tail can be connected to the vehicle body through the bottle tail bracket assembly 3, and the bottle body can be connected to the vehicle body through the bottle body strap 2, so that the connection between the hydrogen bottle 1 and the vehicle body can be achieved from two positions at the same time, which can effectively improve the connection reliability and connection stability between the two. Therefore, when the hydrogen bottle 1 is arranged along the longitudinal direction of the vehicle, it can be avoided that the hydrogen bottle 1 is dislodged and damaged along the longitudinal direction of the vehicle when the vehicle is in a head-on collision. When the hydrogen bottle 1 is arranged along the transverse direction of the vehicle, it can be avoided that the hydrogen bottle 1 is dislodged and damaged along the transverse direction of the vehicle when the vehicle is in a side collision.

[0039] Also, it should be noted that by connecting the hydrogen bottle 1 to the vehicle body at the bottle body and the bottle tail of the hydrogen bottle 1 respectively through the bottle body strap 2 and the bottle tail bracket assembly 3, the space on the vehicle can be fully utilized, the overall vehicle layout can be more reasonable, and the setting of the limit part 12 at the bottle head can be reduced, and the inability to fix the hydrogen bottle 1 from the bottle head due to insufficient space at the bottle head can be avoided.

[0040] Therefore, by setting a bottle valve 11 at the bottle head of the hydrogen bottle 1 to open or close the bottle mouth of the hydrogen bottle 1, by setting a limiting portion 12 and a bottle tail bracket assembly 3 at the bottle tail of the hydrogen bottle 1, and connecting the limiting portion 12 to the vehicle body through the bottle tail bracket assembly 3, and by setting a bottle body strap 2 at the bottle body of the hydrogen bottle 1, and connecting the bottle body to the vehicle body through the bottle body strap 2, the connection between the hydrogen bottle 1 and the vehicle body can be achieved.

[0041] According to the hydrogen bottle assembly 100 of the embodiment of the utility model, the bottle mouth of the hydrogen bottle 1 can be opened or closed by setting the bottle valve 11, and by setting the limiting part 12 at the bottle tail of the hydrogen bottle 1, and connecting the limiting part 12 with the vehicle body through the bottle tail bracket assembly 3, the hydrogen bottle 1 is connected to the vehicle body from the bottle body of the hydrogen bottle 1 through the bottle body strap 2, so that the connection reliability and connection stability between the hydrogen bottle 1 and the vehicle body can be improved, and the hydrogen bottle 1 can be prevented from being axially dislodged and damaged when the vehicle collides, and the space on the vehicle can be fully utilized to make the layout of the whole vehicle more reasonable.

[0042] In some embodiments, the fixed bracket 32 ​​includes two sub-brackets 321, one of the two sub-brackets 321 is connected to the connecting bracket 31, the two sub-brackets 321 are connected by a first connecting member 33 and define a limiting groove 322, and the limiting portion 12 is limitedly disposed in the limiting groove 322.

[0043] Specifically, the fixed bracket 32 ​​is used to be connected to the hydrogen bottle 1, so that the fixed bracket 32 ​​includes two sub-brackets 321, and the two sub-brackets 321 are connected by the first connecting member 33, so that the fixed bracket 32 ​​can be a whole, so as to improve the structural strength of the fixed bracket 32, and the two sub-brackets 321 define a limiting groove 322, and the limiting groove 322 is used to penetrate the limiting portion 12, that is, the connection between the fixed bracket 32 ​​and the hydrogen bottle 1 can be achieved through the cooperation between the limiting groove 322 and the limiting portion 12, and, by connecting one of the two sub-brackets 321 to the connecting bracket 31, the connection between the fixed bracket 32 ​​and the connecting bracket 31 can be achieved, and then the connection between the hydrogen bottle 1 and the vehicle body can be achieved.

[0044] In such Figure 1-Figure 2 In the illustrated embodiment, the two sub-brackets 321 are connected by two first connecting members 33 that are spaced apart from each other, which can improve the connection reliability and stability between the two sub-brackets 321, and further improve the connection reliability between the fixed bracket 32 ​​and the limiting portion 12. The first connecting member 33 can be a bolt.

[0045] And, it should be noted that if Figure 3 As shown, rubber strips 4 can be provided on the inner sides of the two sub-brackets 321 to prevent the sub-brackets 321 from directly contacting the limiting portion 12 to produce abnormal noise, to prevent the limiting portion 12 from being worn or scratched, and to play a buffering role, reducing the impact and vibration of external forces on the hydrogen bottle 1.

[0046] In some embodiments, the limiting portion 12 includes an axial extension portion 121 and a radial extension portion 122, one end of the axial extension portion 121 is connected to the bottle tail of the hydrogen bottle 1 and the other end is connected to the radial extension portion 122, the outer diameter of the radial extension portion 122 is larger than the outer diameter of the axial extension portion 121, the axial extension portion 121 is inserted into the limiting groove 322, and the radial extension portion 122 is limited and pressed against the end face of the sub-bracket 321.

[0047] That is to say, the limiting portion 12 includes two parts, namely an axial extension portion 121 and a radial extension portion 122. The axial extension portion 121 extends along the axial direction of the hydrogen bottle 1, and one end is connected to the bottle tail of the hydrogen bottle 1 to realize the connection between the limiting portion 12 and the hydrogen bottle 1, and the other end is connected to the radial extension portion 122, so that the limiting portion 12 is a whole, which can improve the overall structural strength of the limiting portion 12, and the axial extension portion 121 can be used to separate the hydrogen bottle 1 from the radial extension portion 122 to avoid interference between the two, which makes it impossible to connect the hydrogen bottle 1 to the vehicle body. At the same time, the axial extension portion 121 is inserted into the limiting groove 322, so that the connection between the hydrogen bottle 1 and the fixed bracket 32 ​​can be realized through the cooperation between the axial extension portion 121 and the limiting groove 322.

[0048] Furthermore, the radial extension portion 122 extends radially of the hydrogen bottle 1, that is, the radial extension portion 122 extends radially from the outer side surface of the axial extension portion 121 along the radial direction of the hydrogen bottle 1, and the radial extension portion 122 has a certain length radially of the hydrogen bottle 1, so that the outer diameter of the radial extension portion 122 can be greater than the outer diameter of the axial extension portion 121, and the radial extension portion 122 is limited and pressed against the end surface of the sub-bracket 321, that is, the radial extension portion 122 and the sub-bracket 321 are limited and cooperated, and the hydrogen bottle 1 is axially limited to prevent the hydrogen bottle 1 from being axially dislodged and damaged when a vehicle collision occurs.

[0049] In some embodiments, the width of the sub-bracket 321 is smaller than the length of the axial extension portion 121 , and a movable gap 323 is formed between the sub-bracket 321 and the radial extension portion 122 and / or between the sub-bracket 321 and the tail of the hydrogen bottle 1 .

[0050] Specifically, the two sub-brackets 321 jointly define a limiting groove 322, and the limiting groove 322 realizes the connection between the fixed bracket 32 ​​and the limiting portion 12 by cooperating with the axial extension portion 121. Even if the axial extension portion 121 can be inserted into the limiting groove 322 to cooperate with the limiting groove 322, the width of the sub-bracket 321 is smaller than the length of the axial extension portion 121, which can avoid the interference between the sub-bracket 321 and the radial extension portion 122 or the bottle tail of the hydrogen bottle 1, so that the sub-bracket 321 can cooperate with the axial extension portion 121 to achieve limiting. The connection between the sub-bracket 321 and the radial extension portion 122 and the fixed bracket 32 ​​is improved, and an active gap 323 is formed between the sub-bracket 321 and the radial extension portion 122 or the bottle tail of the hydrogen bottle 1, or an active gap 323 is formed between the sub-bracket 321 and the radial extension portion 122 and the bottle tail of the hydrogen bottle 1, so that when the hydrogen bottle 1 expands, enough space can be left for the hydrogen bottle 1 through the active gap 323, avoiding that the bottle tail of the hydrogen bottle 1 is completely fixed, so that the hydrogen bottle 1 can only be displaced through the bottle valve 11 when it expands, resulting in difficulty in assembling or damage to the pipeline at the bottle valve 11.

[0051] In such Figure 1-Figure 3 In the illustrated embodiment, an active gap 323 is formed between the sub-bracket 321 and the radial extension portion 122 and the bottle tail of the hydrogen bottle 1, so that sufficient space can be left for the expansion of the hydrogen bottle 1 through the two active gaps 323 at the same time to avoid damage to the hydrogen bottle 1.

[0052] In some embodiments, the hydrogen bottle 1 and the fixing bracket 32 ​​are multiple and matched one by one, and the multiple fixing brackets 32 are all connected to one connecting bracket 31.

[0053] Specifically, the hydrogen bottle 1 is used to store hydrogen. Multiple hydrogen bottles 1 can be set on the vehicle at the same time to increase the storage capacity of hydrogen, thereby improving the vehicle's endurance. The fixed bracket 32 ​​is used to connect with the hydrogen bottle 1 to achieve the installation of the hydrogen bottle 1 on the vehicle. Multiple fixed brackets 32 can be set at the same time, and the fixed brackets 32 and the hydrogen bottles 1 are made to correspond one to one, that is, for each hydrogen bottle 1, a fixed bracket 32 ​​is provided and connected thereto to achieve its installation on the vehicle, which can improve the reliability of the installation of the hydrogen bottle 1, and the connecting bracket 31 is used to achieve the connection between the fixed bracket 32 ​​and the vehicle body, that is, to achieve the installation of the hydrogen bottle 1 on the vehicle, multiple fixed brackets 32 can be connected to one connecting bracket 31, that is, the connection between multiple fixed brackets 32 and the vehicle body can be achieved only through one connecting bracket 31, which can reduce the number of connecting brackets 31 and reduce the setting cost.

[0054] For example, Figure 1-Figure 2 As shown, two hydrogen bottles 1 and two fixing brackets 32 are simultaneously provided in the hydrogen bottle assembly 100. The two hydrogen bottles 1 can increase the storage capacity of hydrogen and improve the endurance of the vehicle. The two fixing brackets 32 are respectively connected to the two hydrogen bottles 1 to realize the connection between the two hydrogen bottles 1 and the vehicle, and the reliability of the installation of the hydrogen bottles 1 can be improved.

[0055] In some embodiments, the connecting bracket 31 includes a plurality of sub-segments 311 connected by bending, and the fixing bracket 32 ​​is detachably connected to the sub-segments 311 .

[0056] Specifically, the connecting bracket 31 is used to realize the connection between the fixed bracket 32 ​​and the vehicle body, that is, to realize the connection between the hydrogen bottle 1 and the vehicle body, so that the connecting bracket 31 includes a plurality of sub-segments 311, that is, the sub-segments 311 are connected to the fixed bracket 32 ​​to realize the connection between the connecting bracket 31 and the fixed bracket 32, and the fixed bracket 32 ​​and the sub-segments 311 are detachably connected, that is, the fixed bracket 32 ​​and the connecting bracket 31 are detachably connected, and then the fixed bracket 32 ​​and the connecting bracket 31 can be easily connected, or the two can be separated, that is, it is easy to connect the hydrogen bottle 1 to the vehicle body, or to remove the hydrogen bottle 1 from the vehicle. Among them, the fixed bracket 32 ​​can be connected to the sub-segments 311 by bolts, and the connection method is simple, reliable, and easy to operate.

[0057] Among the plurality of fixing brackets 32 , two adjacent fixing brackets 32 are respectively located on two sides of the connecting bracket 31 .

[0058] Specifically, two adjacent fixed brackets 32 among the multiple fixed brackets 32 are respectively connected to the two sides of the connecting bracket 31, that is, two adjacent hydrogen bottles 1 are respectively arranged on the two sides of the connecting bracket 31 to balance the load on both sides of the connecting bracket 31 to avoid deformation of the connecting bracket 31 due to unbalanced force.

[0059] In some embodiments, the bottle body strap 2 includes two sub-straps 21 , the two sub-straps 21 are detachably connected via a second connecting member 22 , and the two sub-straps 21 define a receiving cavity 23 for passing the bottle body.

[0060] Specifically, the bottle body strap 2 is used to connect the hydrogen bottle 1 to the vehicle body from the bottle body of the hydrogen bottle 1, so that the bottle body strap 2 includes two sub-straps 21, and the two sub-straps 21 are connected through the second connecting member 22, so that the two sub-straps 21 can jointly define a receiving cavity 23, and the receiving cavity 23 is used to receive the bottle body, that is, the connection between the bottle body strap 2 and the hydrogen bottle 1 can be achieved through the cooperation between the receiving cavity 23 and the bottle body, and then the connection between the hydrogen bottle 1 and the vehicle body can be achieved through the bottle body strap 2, and the two sub-straps 21 are detachably connected, so that the two sub-straps 21 can be easily connected or separated. When the two sub-straps 21 are connected, the hydrogen bottle 1 can be fixed, and when the two sub-straps 21 are separated, the hydrogen bottle 1 can be placed in the receiving cavity 23 or removed from the receiving cavity 23. The second connecting member 22 can be a bolt.

[0061] like Figure 1-Figure 2 As shown, connecting the two sub-straps 21 through two spaced-apart second connecting members 22 can improve the connection reliability and stability between the two sub-straps 21, improve the reliability of fixing the hydrogen bottle 1 using the sub-straps 21, and make the bending curvature of the two sub-straps 21 adapt to the shape of the hydrogen bottle 1, so as to improve the reliability of fixing the hydrogen bottle 1 using the bottle body strap 2.

[0062] In some embodiments, there are multiple hydrogen bottles 1, and the sub-strap 21 is formed with multiple strap grooves 24. The multiple strap grooves 24 of two sub-straps 21 are distributed opposite to each other in a one-to-one manner to define a plurality of accommodating cavities 23, and the bottle bodies of the multiple hydrogen bottles 1 are passed through the multiple accommodating cavities 23 in a one-to-one manner.

[0063] Specifically, the sub-strap 21 is formed with a plurality of strap grooves 24, and the plurality of strap grooves 24 on the two sub-straps 21 are distributed in one-to-one correspondence, that is, each group of two relatively distributed strap grooves 24 can define a accommodating cavity 23 to accommodate the hydrogen bottle 1, and the bottle bodies of the plurality of hydrogen bottles 1 can be inserted into the plurality of accommodating cavities 23 in one-to-one correspondence, that is, for each hydrogen bottle 1, a accommodating cavity 23 is provided corresponding to it to accommodate it, which can improve the reliability of fixing the hydrogen bottle 1 using the bottle body strap 2.

[0064] And, if Figure 1-Figure 2 As shown, the number of hydrogen bottles 1 is two, so that each sub-strap 21 forms two strap grooves 24, and the two sub-straps 21 form two accommodating cavities 23 to accommodate the two hydrogen bottles 1 one by one, thereby improving the reliability of fixing the hydrogen bottles 1.

[0065] In some embodiments, the distance between the bottle body band 2 and the bottle head is smaller than the distance between the bottle body band 2 and the bottle tail.

[0066] Specifically, the hydrogen bottle 1 can be connected to the vehicle body from the tail of the hydrogen bottle 1 through the bottle tail bracket assembly 3, and the hydrogen bottle 1 can be connected to the vehicle body from the bottle body of the hydrogen bottle 1 through the bottle body strap 2, so that the distance between the bottle body strap 2 and the bottle head is smaller than the distance between the bottle body strap 2 and the bottle tail, that is, the bottle body strap 2 can be closer to the bottle head, so as to increase the connection length between the hydrogen bottle 1 and the vehicle body, and increase the connection reliability and stability between the two.

[0067] Also, it should be noted that a spring 5 can be set between the two hydrogen bottles 1, and the spring 5 can be set on the bottle body strap 2 to absorb the energy of the vehicle when a collision occurs, reduce the possibility of damage to the hydrogen bottle 1, and reduce the number of springs 5 ​​used, and reduce the installation cost. In actual use, if the middle spring 5 cannot meet the layout requirements, a spring 5 can be set on each side of the two hydrogen bottles 1 away from each other to absorb the energy of the vehicle when a collision occurs, reduce the impact on the hydrogen bottle 1, and the two springs 5 ​​can be set up, down or tilted at the same time, and the setting method can be flexibly selected according to the position of the surrounding parts.
