DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] Reference below Figure 1-Figure 6Describe the hydrogen bottle assembly 100 according to the embodiment of the utility model, the position of the limiter 5 on the valve seat 12 is adjustable, that is, the position of the limiter 5 relative to the hydrogen bottle body 11 is adjustable, so that the width between the limiter 5 and the hydrogen bottle body 11 for installing the limiter bracket 3 is adjustable, and the limiter bracket 3 can be strengthened or replaced with a different limiter bracket 3 according to actual conditions; when the collision force is small, such as the hydrogen bottle 1 is arranged along the lateral direction of the vehicle and is subjected to side collision force, the width of the limiter bracket 3 can be reduced; when the collision force is large, such as the hydrogen bottle 1 is arranged along the longitudinal direction of the vehicle and is subjected to head-on collision force, the width of the limiter bracket 3 can be increased, and the cost-weight of the limiter bracket 3 is optimized while ensuring the strength of the limiter bracket 3. In addition, the elastic member 74 is arranged between the two sub-straps 611 of the first strap 61, and is not arranged at the connection position of the first strap 61 and the second strap 62, which avoids the problem that the elastic member 74 has insufficient minimum clearance from the ground on one side and interferes with the top of the mounting seat 2 on the other side.

[0029] like Figure 1-6 As shown, the hydrogen bottle assembly 100 of the embodiment of the utility model includes: a mounting seat 2, a hydrogen bottle 1, a limiting bracket 3 and a limiting member 5.

[0030] Among them, the mounting seat 2 is connected to the vehicle body, and the mounting seat 2 is provided with a mounting groove 21; the hydrogen bottle 1 is installed in the mounting groove 21 and is bound circumferentially by the binding structure 6, the hydrogen bottle 1 includes a hydrogen bottle body 11 and a valve seat 12 located at the end of the hydrogen bottle body 11, the valve seat 12 is used to install the valve body 13, the limit member 5 is connected to the valve seat 12, the limit bracket 3 is supported on the valve seat 12 and is located between the limit member 5 and the hydrogen bottle body 11, both ends of the limit bracket 3 are connected to the mounting seat 2, and the distance between the limit member 5 and the hydrogen bottle body 11 is adjustable to install different limit brackets 3.

[0031] In practice, the mounting seat 2 can be integrally formed with the vehicle body, or can be detachably connected to the vehicle body, and the mounting seat 2 is provided with a mounting groove 21. By installing the hydrogen bottle 1 in the mounting groove 21, the vehicle installation space is saved, and the hydrogen bottle 1 can be better protected. In addition, the hydrogen bottle 1 includes a hydrogen bottle body 11 and a valve seat 12 located on the hydrogen bottle body 11. The valve seat 12 is used to install a valve body 13. The valve body 13 is suitable for supplying the hydrogen stored in the hydrogen bottle body 11 to the outside when it is opened, or for inputting hydrogen into the hydrogen bottle body 11, and closing the valve body 13, so that the hydrogen can be stored for a long time; that is, the valve seat 12 is used as a structure for installing the valve body 13, supports the valve body 13, and cooperates with the valve body 13.

[0032] Furthermore, when the limiter 5 is connected to the valve seat 12, the limiter bracket 3 is supported on the valve seat 12 and the limiter bracket 3 is located in the space between the limiter 5 and the hydrogen bottle body 11. When the hydrogen bottle 1 is hit head-on, it may fall out axially. The limiter bracket 3 is connected to the mounting seat 2 and supported on the valve seat 12. The limiter bracket 3 can limit the hydrogen bottle 1 axially, making it difficult for the hydrogen bottle 1 to fall out axially. The space between the limiter 5 and the hydrogen bottle body 11 can be used as the installation space of the limiter bracket 3. When the limiter bracket 3 needs to be strengthened, the structure of the limiter bracket 3 changes, and the space between the corresponding limiter 5 and the hydrogen bottle body 11 can be adjusted to a space suitable for the installation of the limiter bracket 3.

[0033] That is to say, the limit member 5 is adjusted on the valve seat 12 to be close to or away from the hydrogen bottle body 11, and the installation width of the limit bracket 3 is set by adjusting the position of the limit member 5 relative to the hydrogen bottle body 11. If the collision force is small, such as when the hydrogen bottle 1 is arranged along the lateral direction of the vehicle and is subjected to side collision force, the width of the limit bracket 3 can be reduced; if the collision force is large, such as when the hydrogen bottle 1 is arranged along the longitudinal direction of the vehicle and is subjected to head-on collision force, the width of the limit bracket 3 can be increased. That is, the position of the limit member 5 relative to the hydrogen bottle body 11 is adjusted according to actual conditions, so that limit brackets 3 of different widths can be installed between the limit member 5 and the hydrogen bottle body 11, so as to achieve the optimal effect of weight and cost of the limit bracket 3 while ensuring the strength of the limit bracket 3.

[0034] Therefore, the hydrogen bottle assembly 100 of the embodiment of the utility model solves the problem in the prior art that the width of the limit bracket 3 axially arranged with the hydrogen bottle 1 is a fixed width and the size of the limit bracket 3 cannot be adjusted for applicability. The position of the limit member 5 relative to the valve seat 12 is adjustable, so that the width between the limit member 5 and the hydrogen bottle body 11 for installing the limit bracket 3 is adjustable, and the limit bracket 3 can be strengthened or replaced with a different limit bracket 3 according to actual conditions.

[0035] In some embodiments, an outer circumference of one end of the valve seat 12 is provided with an external thread 121 , the limiting member 5 is constructed as a limiting ring, the inner circumference of the limiting ring is provided with an internal thread, and the limiting ring is sleeved on the outer circumference of the valve seat 12 and threadedly connected to the valve seat 12 .

[0036] In practice, by means of a threaded connection between the limit ring and the valve seat 12, the limit ring can be located at different positions of the valve seat 12, and the distance between the limit ring and the hydrogen bottle body 11 can be set to be different, so as to facilitate the installation of different limit brackets 3.

[0037] Reference Figure 2 and Figure 4As shown, the valve seat 12 is constructed to extend axially along one end of the hydrogen bottle body 11, and a mounting hole is provided in the middle of the valve seat 12, and the valve body 13 is inserted into the mounting hole of the valve seat 12 so that the valve body 13 is installed on the valve seat 12; the outer periphery of the end of the valve seat 12 away from the hydrogen bottle body 11 is provided with an external thread 121, and the limiting ring is constructed as a metal ring, and the metal ring is provided with an internal thread matching the external thread 121 of the valve seat 12, the metal ring is sleeved on the external thread 121 of the valve seat 12, and is detachably connected relative to the valve seat 12, and the axial position of the metal ring on the valve seat 12 is different, and the space reserved for installing the limiting bracket 3 is different to adapt to the installation of limiting brackets 3 of different widths.

[0038] In some embodiments, a mounting structure 4 is further provided between the limiting bracket 3 and the limiting member 5 . The mounting structure 4 is sleeved on the valve seat 12 , and one side of the mounting structure 4 is connected to the limiting bracket 3 , and the limiting member 5 is pressed against the other side of the mounting structure 4 .

[0039] In practice, the mounting structure 4 between the limit bracket 3 and the limit member 5 is connected to the limit bracket 3, which is equivalent to strengthening the strength of the limit bracket 3 supporting the valve seat 12, and at this time the limit member 5 is threadedly connected to the valve seat 12, the limit member 5 is pressed against the mounting structure 4, and the mounting structure 4 is also detachably connected to the limit bracket 3, which is equivalent to improving the stability of the limit bracket 3 supporting and limiting the valve seat 12.

[0040] Specifically, the nut is welded inside the limit bracket 3, the mounting structure 4 and the limit bracket 3 are connected by bolts, and then the connected mounting structure 4 and the limit bracket 3 are installed on the valve seat 12 of the hydrogen bottle 1, and then fastened with a threaded metal ring, and finally the valve body 13 is installed; the mounting structure 4 and the limit bracket 3 are detachably connected, and the limit bracket 3 and the mounting seat 2 are also detachably connected. During actual disassembly, after removing the valve body 13, the metal ring can be removed first, and then the mounting structure 4 and the limit bracket 3 can be disassembled, and finally the limit bracket 3 can be disassembled. When any component is damaged, it can be replaced separately, saving replacement and maintenance costs.

[0041] In some embodiments, the mounting structure 4 includes a semi-enclosed sleeve portion 41 , with connecting portions 42 provided at both ends of the sleeve portion 41 . When the sleeve portion 41 is sleeved on the valve seat 12 , the two connecting portions 42 are connected by a connecting piece, and a gap is left between the two connecting portions 42 .

[0042] When the sleeve portion 41 is sleeved on the outer periphery of the valve seat 12 , the gap between the two connecting portions 42 of the sleeve portion 41 can absorb the manufacturing tolerance, so that the limiting bracket 3 is better fixed on the valve seat 12 .

[0043] Reference Figure 4As shown, the sleeve portion 41 of the mounting structure 4 is sleeved on the outer periphery of the valve seat 12, and the sleeve portion 41 can be constructed as a semi-closed circular structure. Connecting portions 42 are respectively provided at both ends of the sleeve portion 41, and the two connecting portions 42 are opposite to each other with a gap. Each connecting portion 42 is provided with a connecting hole 421, and the two connecting portions 42 are opposite to each other. The connecting piece can use a longer through bolt 422, and the through bolt 422 passes through the two connecting portions 42 in sequence to connect the two connecting portions 42; the two connecting portions 42 can be made of metal material, which makes it easy to leave a gap between the two connecting portions 42 to prevent the two connecting portions 42 from being close to each other and tightly pressed during extrusion. At the same time, the connection strength and reliability of the two connecting portions 42 can be enhanced by constructing the connecting portion 42 as a metal material.

[0044] In some embodiments, a buffer material is disposed on the inner periphery of the sleeve portion 41 , and the buffer material is in contact with the outer periphery of the valve seat 12 .

[0045] In practice, the inner circumference of the sleeve portion 41 can be set to vulcanized rubber to prevent the mounting structure 4 from directly contacting the valve seat 12 and causing abnormal noise, and at the same time can buffer the force on the valve seat 12. Figure 4 As shown, the inner periphery of the sleeve portion 41 that is in direct contact with the valve seat 12 may be provided with a rubber material, while the outer periphery of the sleeve portion 41 is provided with a metal material to ensure the strength of the entire mounting structure 4, and the connecting portions 42 at both ends of the sleeve portion 41 are also provided with a metal material to ensure the connection strength while maintaining a gap between the two connecting portions 42, thereby better absorbing the manufacturing tolerance and improving the reliability and stability of the connection of the limit bracket 3.

[0046] In some embodiments, the limiting bracket 3 includes a middle supporting section 31 and connecting sections 32 connected to both sides of the supporting section 31. The connecting sections 32 on both sides of the supporting section 31 are bent to form a supporting groove. The supporting groove is supported on the valve seat 12, and the connecting sections 32 on both sides are connected to the mounting seat 2.

[0047] In practice, the support section 31 of the limiting bracket 3 is used to support the valve seat 12, and the support section 31 is constructed as a support groove. The support section 31 can also limit the valve seat 12 radially while supporting the valve seat 12, and the connecting section 32 is connected to the mounting seat 2, so that the limiting bracket 3 can axially limit the hydrogen bottle body 11. The sleeve portion 41 of the mounting structure 4 extends radially to form an extended flange 411, which is connected to the limiting bracket 3, and the extended flange 411 of the mounting structure 4 is pressed against the support section 31 of the limiting bracket 3 and the junction of the support section 31 and the connecting section 32, so as to improve the axial limiting effect of the limiting bracket 3 on the hydrogen bottle body 11.

[0048] Furthermore, the limit bracket 3 is a sheet metal part with a hollow cavity inside, which has lower cost and lighter weight than castings, and the sheet metal part with a hollow cavity can reduce weight and have a better buffering effect; in addition, referring to Figure 2 As shown, both ends of the limit bracket 3 are provided with a sleeve 33 perpendicular to the connecting section 32. The connecting bolt passes through the sleeve 33 and connects the limit bracket 3 to the mounting seat 2, thereby enhancing the force-bearing area of ​​the connection between the limit bracket 3 and the mounting seat 2, ensuring the strength of the installation point of the connecting bolt, and enhancing the connection reliability of the limit bracket 3.

[0049] In some embodiments, the strap structure 6 includes a first strap 61 and a second strap 62 , which are opposite to and together surround the outer circumference of the hydrogen bottle body 11 and are connected to the mounting base 2 through a first connecting component 8 .

[0050] In practice, two or more strap structures 6 can be provided, such as generally provided as two, the two strap structures 6 are distributed spaced apart along the axial direction of the hydrogen bottle 1, and each strap structure 6 includes a first strap 61 and a second strap 62 which are arranged opposite to each other, that is, the first strap 61 is wrapped around one side of the axial center line of the hydrogen bottle 1, and the second strap 62 is wrapped around the other side of the axial center line of the hydrogen bottle 1.

[0051] Specifically, refer to Figure 1 As shown, the first strap 61 and the second strap 62 can be fixed to the mounting base 2 through the first connecting component 8. By setting the connection method of the first strap 61 and the second strap 62, it is convenient to adjust the space enclosed by the first strap 61 and the second strap 62 according to actual conditions, so that corresponding adjustments can be made according to the actual size of the hydrogen bottle 1.

[0052] Furthermore, the first connecting component 8 includes a fixing frame 81 and a fixing member 82, the fixing member 82 is a bolt, and the structure of the fixing frame 81 is similar to a "π"-shaped structure, and the top surface of the "π"-shaped structure is connected to the strap structure 6, such as a first connecting ear is provided at the end of the first strap 61, and a second connecting ear is provided at the end of the second strap 62, the first connecting ear and the second connecting ear are connected, and at least one of the first connecting ear and the second connecting ear is connected to the top surface of the "π"-shaped structure of the fixing frame 81 by a bolt, so as to realize the first strap 61 and the second strap 62 being wrapped around the hydrogen bottle body 11 while realizing the detachable connection between the strap structure 6 and the mounting seat 2.

[0053] In some embodiments, one of the first strap 61 and the second strap 62 includes two sub-straps 611 , and the two sub-straps 611 are connected by a second connecting component 7 .

[0054] In practice, by configuring one of the first strap 61 and the second strap 62 to include two sub-straps 611 , an adjustment space can be left between the two sub-straps 611 , so that the tightness of the entire strap structure 6 can be adjusted to adapt to the impact of vehicle vibration, or to adapt to different sizes of hydrogen bottles 1 .

[0055] like Figure 6 As shown, the first strap 61 includes two sub-straps 611, and the two sub-straps 611 are connected through the second connecting assembly 7, and the two sub-straps 611 are connected to form the first strap 61, and then the first strap 61 and the second strap 62 are connected to achieve the circumferential upper limit of the hydrogen bottle body 11 by the strap structure 6. Of course, the second strap 62 can also be set to include two sub-straps 611, and the two sub-straps 611 are connected to form the second strap 62, and then the second strap 62 and the first strap 61 are connected. If the first strap 61 includes two sub-straps 611, the tightness of the first strap 61 can be adjusted by adjusting the tightness of the two sub-straps 611, so that the tightness of the strap structure 6 surrounded by the first strap 61 and the second strap 62 can be adjusted.

[0056] In some embodiments, the second connecting component 7 includes a connecting frame 71, an elastic member 74, a stud 73 and a nut 72. The connecting frame 71 includes two sub-frames. The two sub-straps 611 are connected to a sub-frame at their ends close to each other. The elastic member 74 is sleeved on the stud 73. The stud 73 passes through the two sub-frames in turn and the ends are fastened and connected by nuts 72. The elastic member 74 is used to pre-tighten the two sub-straps 611.

[0057] In practice, the two sub-straps 611 can be pre-tightened or loosened by the elastic member 74, so as to adaptively adjust the tightness between the two sub-straps 611, and further adjust the size of the space enclosed by the first strap 61 and the second strap 62, which has a better circumferential limiting effect on the hydrogen bottle 1.

[0058] like Figure 6As shown, the elastic member 74 is a spring, the first strap 61 includes two sub-straps 611, the stud 73 passes through the sub-frame at the end of the first strap 61 and the sub-frame at the end of the second strap 62, and the ends are connected by a nut 72 to achieve the connection of the two sub-straps 611; and the stud 73 is also sleeved with a spring, which is located between a sub-frame and the head of the stud 73. When the spring is squeezed, it can give a force to one sub-frame to approach another sub-frame, so that the two sub-straps 611 are close to each other, that is, the two sub-straps 611 are pre-tightened, so that the entire strap structure 6 can better limit the circumferential position of the hydrogen bottle 1. In addition, the spring is located at the connection of the two sub-straps 611 in the mounting groove 21, and is not arranged at the connection position of the first strap 61 and the second strap 62, avoiding the problem of insufficient minimum ground clearance of the spring on one side and interference of the spring with the vehicle body mounting seat 2 on the other side. Figure 6 The lower part of the medium hydrogen bottle 1 is close to the ground, which avoids the problem of insufficient minimum ground clearance when the spring is facing downward and interference between the spring and the vehicle body mounting seat 2 when the spring is facing upward.

[0059] The embodiment of the utility model discloses a vehicle, including the above-mentioned hydrogen bottle assembly 100, the position of the limit member 5 relative to the valve seat 12 is adjustable, so that the width between the limit member 5 and the hydrogen bottle body 11 for installing the limit bracket 3 is adjustable, and the limit bracket 3 is strengthened or replaced with a different limit bracket 3 according to the actual situation, which can reduce the width of the limit bracket 3 or increase the width of the limit bracket 3, and achieve the optimal cost-weight of the limit bracket 3 while ensuring the strength of the limit bracket 3, thereby improving the limiting effect on the hydrogen bottle 1, thereby improving the safety of the hydrogen bottle 1, and thus improving driving safety.
