DETAILED DESCRIPTION
[0028] 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.
[0029] Reference below Figure 1-Figure 5According to the hydrogen bottle mounting structure 100 of the embodiment of the utility model, the hydrogen bottle 2 is arranged in the mounting groove 12 of the mounting seat 1, so that the hydrogen bottle 2 will not move within a large range, and a limiting structure 3 is arranged in the mounting groove 12, and the limiting structure 3 is arranged at both ends of the hydrogen bottle 2 to prevent the axial movement of the hydrogen bottle 2, and the limiting structure 3 and the valve body 4 of the hydrogen bottle 2 are staggered, and the axial limiting and the normal operation of the valve body 4 are ensured. The hydrogen bottle mounting structure 100 of the embodiment of the utility model will not fall off from the strap structure 5 when the vehicle collides, and the valve body 4 is prevented from being hit, thereby avoiding the problem of damage and leakage of the bottle valve of the hydrogen bottle 2.
[0030] like Figure 1-Figure 5 As shown, the hydrogen bottle mounting structure 100 according to the embodiment of the utility model includes: a mounting seat 1 and a limiting structure 3.
[0031] Among them, the mounting seat 1 is suitable for being connected to the vehicle body, and a mounting groove 12 for accommodating the hydrogen bottle 2 is formed in the mounting seat 1, and the mounting seat 1 is also connected to a strap structure 5 for restraining the hydrogen bottle 2; a limiting structure 3 is installed on the mounting seat 1, and the limiting structure 3 is located at the end in the mounting groove 12, and the limiting structure 3 is pressed against the end of the hydrogen bottle 2 for axial limitation, and the limiting structure 3 and the valve body 4 of the hydrogen bottle 2 are staggered.
[0032] In practice, the mounting seat 1 can be integrally formed with the vehicle body, or connected to the vehicle body through a connecting piece, and the mounting seat 1 is provided with a mounting groove 12, and the hydrogen bottle 2 is installed in the mounting groove 12, and the circumference of the hydrogen bottle 2 is fixed by the binding structure 5. First, the hydrogen bottle 2 can be initially placed in the mounting groove 12, and the installation space of the vehicle can be saved. Among them, the limiting structure 3 can be installed in the mounting groove 12, and can also be installed at the upper two ends of the mounting groove 12. The limiting structure 3 is mainly used to block the axial ends of the hydrogen bottle 2 to prevent the axial movement of the hydrogen bottle 2 when the hydrogen bottle 2 produces axial displacement.
[0033] Specifically, no matter the limiting structure 3 is installed in the mounting groove 12 or at the two ends above the mounting groove 12, the limiting structure 3 avoids the valve body 4 of the hydrogen bottle 2. A valve body 4 is provided at one axial end of the hydrogen bottle 2. The valve body 4 is used to control the opening or closing of the hydrogen bottle 2. When the limiting structure 3 avoids the valve body 4, the limiting structure 3 can not only limit the axial position of the hydrogen bottle 2, but also the valve body 4 can operate normally.
[0034] Furthermore, the valve body 4 can be arranged at the axial end of the hydrogen bottle 2 and in the middle position in the radial direction. When the limiting structure 3 is located in the mounting groove 12, the limiting structure 3 can contact the end of the hydrogen bottle 2 and in the radial lower position to avoid the valve body 4. When the limiting structure 3 is located at the upper ends of the mounting groove 12, the limiting structure 3 can contact the end of the hydrogen bottle 2 and in the radial upper position to avoid the valve body 4. The setting of the limiting structure 3 can be designed according to actual conditions, as long as it can satisfy the axial end limit of the hydrogen bottle 2.
[0035] Therefore, the hydrogen bottle mounting structure 100 of the embodiment of the utility model first fixes the hydrogen bottle 2 circumferentially by the binding structure 5, and also sets the limiting structures 3 at both ends of the mounting seat 1 to limit the axial position of the hydrogen bottle 2, so as to prevent the hydrogen bottle 2 from moving axially and causing the valve body 4 to be hit, so as to avoid the problem that the hydrogen bottle 2 escapes from the binding structure 5 axially and causes the valve body 4 of the hydrogen bottle 2 to be damaged and leaked, thereby improving the safety of the use of the hydrogen bottle.
[0036] In some embodiments, both ends of the inner bottom of the mounting groove 12 are provided with a limiting structure 3, and the limiting structure 3 is constructed as a limiting block; wherein the limiting block is provided with a first curved surface 31, and the end of the hydrogen bottle 2 is provided with a second curved surface 111, and the first curved surface 31 and the second curved surface 111 are limited and pressed.
[0037] Reference Figure 1-3 As shown, the limiting structure 3 is arranged at the two ends of the inner bottom of the installation groove 12, and the limiting structure 3 is a limiting block. The limiting block can be connected to the side wall and the bottom wall of the installation groove 12 as a whole. The limiting block is provided with a first arc surface 31 at the position facing the end of the hydrogen bottle 2. When the hydrogen bottle 2 moves axially, the axial end of the hydrogen bottle 2 and the radial lower position contact the limiting block, specifically, the second arc surface 111 of the hydrogen bottle 2 is pressed against the first arc surface 31 of the limiting block. In practice, when the hydrogen bottle 2 is detachably installed in the installation groove 12, the second arc surface 111 of the hydrogen bottle 2 is pressed against the first arc surface 31 of the limiting block. There may be a gap between the first curved surface 31 of the limiting structure 3, or the second curved surface 111 of the hydrogen bottle 2 is in direct contact with the first curved surface 31. When there is a gap between the second curved surface 111 of the hydrogen bottle 2 and the first curved surface 31 of the limiting structure 3, if the hydrogen bottle 2 has axial displacement, the hydrogen bottle 2 can be quickly pressed and limited by the limiting structure 3. When the second curved surface 111 of the hydrogen bottle 2 is in direct contact with the first curved surface 31, the hydrogen bottle 2 will not move axially, thereby preventing the hydrogen bottle 2 from axially moving and colliding with the valve body 4 or the hydrogen bottle 2 from escaping from the binding structure 5.
[0038] Thus, the end of the hydrogen bottle 2 is provided with a second arc surface 111, and the limiting block is provided with a first arc surface 31. When the hydrogen bottle 2 is axially limited by the limiting structure 3, the buffering effect is better when the hydrogen bottle 2 contacts the limiting structure 3, and the collision damage of the hydrogen bottle 2 can also be reduced. In addition, it should be noted that a harness hole 36 can be provided on the limiting block, and the harness hole 36 can provide a pipe clamp fixing point for the harness, which is convenient for the arrangement of the pipelines of the whole vehicle.
[0039] In some embodiments, the inner end surface of the installation groove 12 opposite to the valve body 4 is the first inner end surface 13 , and a safety gap is formed between the valve body 4 and the first inner end surface 13 when the first arcuate surface 31 presses against the second arcuate surface 111 .
[0040] In practice, when the valve body 4 is opened, it can be pulled along the axial direction of the hydrogen bottle 2. When the hydrogen bottle 2 contacts the limiting structure 3, the hydrogen bottle 2 will no longer move axially, and a safety gap is set between the valve body 4 and the first inner end face 13. Then, when the valve body 4 is opened, an operating space is provided for the opening of the valve body 4, and the valve body 4 is prevented from colliding with the first inner end face 13 of the mounting groove 12, thereby preventing the leakage of hydrogen in the hydrogen bottle 2 due to collision damage of the valve body 4.
[0041] In some embodiments, the limiting structure 3 is constructed as a limiting bracket, which includes a connected supporting connection part 32 and a resisting part 33. The supporting connection part 32 is detachably connected to the mounting seat 1 and is located on both sides above the mounting groove 12. The resisting part 33 resists the hydrogen bottle 2.
[0042] In practice, a limit bracket is installed on both sides of the upper part of the mounting groove 12 along the axial direction of the hydrogen bottle 2. The supporting connection part 32 of the limit bracket can be detachably connected to the mounting seat 1 by a connecting piece. After the hydrogen bottle 2 is placed in the mounting groove 12, the limit bracket is connected to the mounting seat 1. The abutment part 33 of the limit bracket abuts against the two ends of the hydrogen bottle 2 in the axial direction to limit the axial direction of the hydrogen bottle 2. When disassembling the hydrogen bottle 2, the limit bracket is first disassembled, and then the hydrogen bottle 2 is removed from the mounting groove 12. Limit brackets of different sizes can be set according to the size of the hydrogen bottle 2 to limit the axial direction of the hydrogen bottle 2, and the method of the limit bracket reduces the weight of the limit structure 3.
[0043] Specifically, the supporting connection part 32 can be connected to the upper part of the mounting seat 1 through a plurality of connecting parts, and the supporting connection part 32 and the resisting part 33 can be integrally formed, and the resisting part 33 resists the end of the hydrogen bottle 2 and at the upper position in the radial direction, and the resisting part 33 can also be set to an arc surface, which is limited and pressed against the arc surface at the end of the hydrogen bottle 2, thereby improving the buffering performance of the resisting part 33 on the hydrogen bottle 2 and ensuring the safety of the hydrogen bottle 2.
[0044] In some embodiments, the supporting connection portion 32 is provided with an avoidance opening 35 , and the avoidance opening 35 is used to avoid the valve body 4 .
[0045] Specifically, the supporting connection part 32 is perpendicular to the resisting part 33, the supporting connection part 32 is connected above the mounting groove 12 of the mounting seat 1, the supporting connection part 32 extends along the inner side of the mounting groove 12 and the resisting part 33 is pressed against the end of the hydrogen bottle 2, and by providing an avoidance opening 35 in the supporting connection part 32, the valve body 4 can be opened or closed normally.
[0046] In some embodiments, the blocking portion 33 is provided with a plurality of weight-reducing holes 34 , and the supporting connection portion 32 is provided with a weight-reducing groove 321 .
[0047] Specifically, the blocking portion 33 is constructed as an arc-shaped structure, and the plurality of weight-reducing holes 34 can be constructed as a plurality of arc-shaped strip holes, and the plurality of arc-shaped strip holes are spaced and distributed. At the same time, a weight-reducing groove 321 is provided on the support connection portion 32, and when the support connection portion 32 is connected to the mounting seat 1, a first connecting hole is provided at the weight-reducing groove 321, and a second connecting hole is provided at a corresponding position of the mounting seat 1, and the limiting bracket is connected to the mounting seat 1 through a connecting piece at the weight-reducing groove 321, that is, the connecting piece is hidden in the weight-reducing groove 321, which can reduce the contact between the connecting piece and the external environment or external force, and improve the connection reliability of the connecting piece. At the same time, the thickness of the supporting connection part 32 at the weight-reducing groove 321 is also relatively thin, which can facilitate the quick connection of the connecting part and the mounting seat 1; in actual design, the first connecting hole is opened large to absorb the size and position tolerance of the parts during assembly of the actual vehicle, and at the same time, the connecting part can use a large flange face bolt, or an ordinary flange bolt with a gasket, which increases the contact surface between the bolt and the mounting seat 1 and thus increases the fastening force. The weight-reducing groove 321 of the supporting connection part 32 and the multiple weight-reducing holes 34 of the resisting part 33 can reduce the weight of the limiting bracket, and the weight-reducing groove 321 can also enhance the buffering strength of the supporting connection part 32.
[0048] In some embodiments, the hydrogen bottle mounting structure 100 further includes a buffer protection cover 11 , and two buffer protection covers 11 are respectively covered at both ends of the hydrogen bottle 2 , and the buffer protection cover 11 at one end avoids the valve body 4 so that the valve body 4 extends out of the buffer protection cover 11 .
[0049] In practice, when a buffer protection cover 11 is provided at both ends of the hydrogen bottle 2 structure, the shape of the buffer protection cover 11 matches the shape of the end of the hydrogen bottle 2 and can protect the hydrogen bottle 2. The buffer protection cover 11 can be made of rubber or other materials to increase the buffering performance when the end of the hydrogen bottle 2 is collided; when the limiting structure 3 is constructed as a limiting block and the limiting block is provided with a first curved surface 31, the second curved surface 111 can be provided on the buffer protection cover 11 at this time, so that the buffer protection cover 11 is pressed and matched with the first curved surface 31 of the limiting block, thereby further improving the buffering effect on the hydrogen bottle 2, protecting the hydrogen bottle 2, and improving the safety of the hydrogen bottle 2 when it is collided with external force, while absorbing the tolerance of the hydrogen bottle 2 and the expansion during hydrogenation.
[0050] In some embodiments, the strap structure 5 includes a first strap 51 and a second strap 52 . The first strap 51 and the second strap 52 are opposite to each other and together surround the outer circumference of the hydrogen bottle 2 . The first strap 51 and the second strap 52 are both connected to the upper sides of the mounting groove 12 .
[0051] In practice, the number of the strap structures 5 can be two or more, and generally two. The two strap structures 5 are spaced apart and distributed along the axial direction of the hydrogen bottle 2, and each strap structure 5 includes a first strap 51 and a second strap 52 that are relatively arranged, that is, the first strap 51 is wrapped around one side of the axial center line of the hydrogen bottle 2, and the second strap 52 is wrapped around the other side of the axial center line of the hydrogen bottle 2.
[0052] Specifically, in each strap structure 5, the two ends of the first strap 51 and the second strap 52 are connected and commonly connected to the mounting seat 1 to fix the hydrogen bottle 2 circumferentially. Therefore, by setting the first strap 51 and the second strap 52, after the hydrogen bottle 2 is placed in the mounting groove 12, the hydrogen bottle 2 is first fixed in the mounting groove 12 with the first strap 51 and the second strap 52, and then the two limit brackets are tightened and fixed to the mounting seat 1 by four bolts, and the limit brackets support the axial ends of the hydrogen bottle 2 to limit the axial displacement of the hydrogen bottle 2. By setting the first strap 51 and the second strap 52, it is more convenient to fix the hydrogen bottle 2 circumferentially.
[0053] In some embodiments, the hydrogen bottle mounting structure 100 also includes a connecting assembly 7, the mounting base 1 is provided with a connecting frame 6, the connecting assembly 7 includes a stud 72 and an elastic member 71, the stud 72 is sequentially passed through the first strap 51, the connecting frame 6 and the second strap 52, the elastic member 71 is sleeved outside the stud 72 and is used to elastically pre-tighten the second strap 52 toward the first strap 51.
[0054] Specifically, refer to Figure 5 As shown, a connecting frame 6 is provided at the upper end of the mounting base 1, and one end of the first strap 51 and the second strap 52 are both connected to the connecting frame 6. The structure of the connecting frame 6 is similar to the "π"-shaped structure. The connecting frame 6 includes a connecting ear 61, and the connecting ear 61 is connected to the mounting base 1 through a connecting piece. The connecting ear 61 has a large hole to absorb the size and position tolerance of the parts during the actual vehicle assembly. At the same time, the connecting piece at the connecting ear 61 can use a large flange face bolt, or it can be an ordinary flange bolt plus a gasket, so as to increase the contact surface between the bolt and the mounting base 1 and thereby increase the tightening force.
[0055] Among them, a bending portion 511 is provided at the end of the first strap 51, and the bending portion 511 is connected to the upper part of the connecting frame 6. The stud 72 passes through the second strap 52, the connecting frame 6 and the first strap 51, and the connection between the first strap 51 connected by the stud 72 and the connecting frame 6 is tightened by the nut 721, and a first limiting portion 722 is provided at one end of the stud 72 away from the nut 721, and the end of the second strap 52 is bent to form a second limiting portion 8. The stud 72 passes through the second limiting portion 8 of the second strap 52, the connecting frame 6, and the bending portion 511 of the first strap 51 in sequence and is tightened by the nut 721, and a first limiting portion 722 is provided at one end of the stud 72 away from the nut 721, and the elastic member 71 is sleeved on the stud 72 and one end is pressed against the first limiting portion 722 and the other end is pressed against the second limiting portion 8, and the elastic member 71 is a spring.
[0056] When the vehicle vibrates during driving, the hydrogen bottle 2 produces an up-and-down displacement. For example, when it produces a downward displacement, the spring can give an upward force to the second limiting portion 8 to make the second strap 52 approach the first strap 51, so that the hydrogen bottle 2 is tightened when the first strap 51 and the second strap 52 are together around the outer circumference of the hydrogen bottle 2. When the hydrogen bottle 2 is subjected to vibration, the pre-tightening effect of the first strap 51 and the second strap 52 on the hydrogen bottle 2 can always be maintained to keep the hydrogen bottle 2 circumferentially fixed. At the same time, the elastic member 71 also has a buffering and shock-absorbing effect on the vibration of the hydrogen bottle 2.
[0057] The embodiment of the utility model also discloses a vehicle, including the above-mentioned hydrogen bottle mounting structure 100, wherein the hydrogen bottle 2 is arranged in the mounting groove 12 of the mounting seat 1, so that the hydrogen bottle 2 does not move within a large range, and a limiting structure 3 is arranged in the mounting groove 12, and the limiting structure 3 is arranged at both ends of the hydrogen bottle 2 to prevent the hydrogen bottle 2 from moving axially, and the limiting structure 3 and the valve body 4 of the hydrogen bottle 2 are staggered, and the axial limiting is performed while ensuring the normal operation of the valve body 4. The hydrogen bottle mounting structure 100 of the embodiment of the utility model will not fall off the strap structure 5 when the vehicle collides, and the valve body 4 is prevented from being collided, thereby avoiding the problem of damage and leakage of the valve body of the hydrogen bottle 2, ensuring the safety of the hydrogen bottle 2, and further ensuring the safety of the vehicle driving.
