DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment of a hydrogen storage bottle protection structure, comprising a vehicle body 1, four sets of universal wheels are provided at the bottom end of the vehicle body 1, and the hydrogen storage tank fixed at the top of the vehicle body 1 can be transported by the universal wheels, and the top end of the outer wall of the vehicle body 1 is fixedly connected to a fixed frame 2, and a handle is provided at the top end of the fixed frame 2. Through the cooperation of the handle and the universal wheels at the bottom end of the vehicle body 1, the hydrogen storage tank can be conveniently transported, and the inner wall of the top end of the fixed frame 2 can be slid up and down and connected to two sets of sliding columns 4 through a limit assembly 5. By providing a sliding column 4 that can slide up and down, the sliding column 4 can drive the upper group positioning mechanism 3 to move, so that it can be adjusted according to the height of the hydrogen storage tank, so as to adapt to hydrogen storage tanks of different heights, and the top end of the sliding column 4 and the bottom end of the fixed frame 2 are both provided with a positioning mechanism 3.

[0033] Reference Figure 2 and Figure 3 The positioning mechanism 3 includes a fixed seat 31, and the fixed seat 31 is provided with an upper and lower group. The upper fixed seat 31 is fixedly connected to the top of the outer wall of the sliding column 4, and the lower fixed seat 31 is fixedly connected to the bottom end of the fixed frame 2. By setting the upper group of slidable fixed seats 31 and the fixed seat 31 fixed by the lower group, the cooperation between the two can adjust the compression protection according to the different heights of hydrogen storage tanks. The inner walls of the two groups of fixed seats 31 are penetrated and slidably connected with a sliding rod 32. A telescopic rod 35 is fixedly connected between the two groups of sliding rods 32. The telescopic rod 35 is composed of a large rod body and a small rod body, so that when the upper fixed seat 31 moves with the sliding column 4, the telescopic rod 35 will automatically follow the upper sliding The movement of the movable rod 32 is for extension and retraction. At the same time, the movement of the telescopic rod 35 will also synchronously drive the upper and lower sets of sliding rods 32 to move forward and backward synchronously. The end of the sliding rod 32 away from the telescopic rod 35 is hinged with two sets of hinged rods 33, and the end of the hinged rod 33 away from the sliding rod 32 is hinged with a positioning ring 34. When the two sets of sliding rods 32 move synchronously with the telescopic rod 35, the hinged rod 33 will synchronously pull the two sets of positioning rings 34 to slide laterally on the inner wall of the guide groove of the fixing seat 31, so that the two sets of positioning rings 34 are close to each other to compress the hydrogen storage tanks at different heights to fix them, thereby preventing the hydrogen storage tanks from shaking during transportation and causing damage to the outer shell.

[0034] Reference Figure 2 and Figure 3The hinge rod 33 is slidably connected to the inner wall of the fixed seat 31, and the inner wall of the fixed seat 31 is provided with a cavity, so that the hinge rod 33 can move when following the movement of the sliding rod 32. The outer side of the fixed seat 31 is provided with two sets of guide grooves, and the positioning ring 34 is slidably connected to the inner wall of the guide groove of the fixed seat 31. By providing a guide groove that fits the positioning ring 34 on the surface of the fixed seat 31, the two sets of positioning rings 34 can only move closer to or away from each other on the inner wall of the fixed seat 31, and will not be affected by the hinge rod 33 and move synchronously. The inner side wall of the fixed frame 2 is fixedly connected to a T-shaped rod 36. The T-shaped rod 36 is T-shaped, and one vertical end thereof is provided with multiple sets of through holes, which fit with the end of the insertion rod 39. The surface of the T-shaped rod 36 is slidably connected to the sliding seat 37, and the inner wall of the sliding seat 37 is elastically supported by a limit spring 38 The sliding seat 37 is fixedly connected to the outer wall of the telescopic rod 35, and the movement of the sliding seat 37 can drive the telescopic rod 35 to move, so that the upper and lower sets of sliding rods 32 can be pulled synchronously. One end of the limit spring 38 is fixedly connected to the inner wall of the sliding seat 37, and the other end of the limit spring 38 is fixedly connected to the surface of the insert rod 39. The function of the limit spring 38 is to automatically reset the position of the insert rod 39 after being pulled outward. The insert rod 39 passes through and is slidably connected to the inner wall of the sliding seat 37. The surface of the T-shaped rod 36 has multiple groups of through holes. The end of the insert rod 39 is plugged into the inner wall of the through hole. The plugging between the two can drive the sliding seat 37 to move the telescopic rod 35 to fix the position of the two sets of positioning rings 34 after clamping and positioning according to hydrogen storage tanks of different thicknesses.

[0035] Reference Figure 2 and Figure 4 The inner wall of the positioning ring 34 is elastically connected to the connecting column 6 through the connecting spring 7. One end of the connecting spring 7 is fixedly connected to the surface of the connecting column 6, and the other end of the connecting spring 7 is fixedly connected to the inner wall of the positioning ring 34. The function of the connecting spring 7 is to automatically reset the position of the contact disc 8 after the hydrogen storage tank is compressed. At the same time, it also makes the contact disc 8 exert elastic support on it when it contacts the outer wall of the hydrogen storage tank, thereby preventing the impact of the hydrogen storage tank from being buffered by the elastic action of the connecting spring 7 when the whole is subjected to a collision, thereby avoiding damage to the outer surface of the hydrogen storage tank. The connecting column 6 passes through and is slidably connected to the inner wall of the positioning ring 34. The end of the connecting column 6 is rotatably connected to the contact disc 8. The contact disc 8 is made of rubber material. By contacting the outer wall of the hydrogen storage tank, the damage of the contact disc 8 to the outer shell of the hydrogen storage tank can be reduced when the whole is subjected to a collision.

[0036] Reference Figure 1 and Figure 2The limit assembly 5 includes a pull rod 51, which is elastically connected to the inner wall of the top of the fixed frame 2 by a return spring 52. One end of the return spring 52 is fixedly connected to the surface of the pull rod 51, and the other end of the return spring 52 is fixedly connected to the inner wall of the top of the fixed frame 2. The function of the return spring 52 is to automatically reset the position of the pull rod 51 after it is pulled outward. At the same time, the shape of the pull rod 51 is U-shaped, so as to prevent its inner side from being blocked when the telescopic rod 35 moves. At the same time, the U-shaped setting makes it convenient to pull it with one hand. The pull rod 51 passes through and is slidably connected to the inner wall of the top of the fixed frame 2. The surface of the sliding column 4 is provided with multiple groups of through holes. The end of the pull rod 51 is plugged into the inner wall of the through hole of the sliding column 4. The plugging between the two can drive the sliding column 4 to fix the position of the upper positioning mechanism 3 after adjustment according to the hydrogen storage tanks of different heights.

[0037] Working principle: When adjusting the position of the sliding column 4 to adapt to hydrogen storage tanks of different heights, pull the pull rod 51 outward to disengage the pull rod 51 from the through hole on the surface of the sliding column 4. At this time, the reset spring 52 is stretched. After moving the sliding column 4 to the appropriate position, release the pull rod 51. The pull rod 51 automatically resets under the elastic action of the reset spring 52 and is inserted into the corresponding through hole on the surface of the sliding column 4. The sliding column 4 drives the upper positioning mechanism 3 to fix the position after adjustment according to the hydrogen storage tanks of different heights.

[0038] When the hydrogen storage tank needs to be fixed, the position of the sliding column 4 is adjusted through the limit assembly 5 according to the height of the hydrogen storage tank, so that the upper positioning mechanism 3 moves to an appropriate height. When the upper fixing seat 31 moves with the sliding column 4, it will drive the telescopic rod 35 to automatically extend and retract. The movement of the telescopic rod 35 synchronously drives the upper and lower sliding rods 32 to move forward and backward.

[0039] The sliding seat 37 drives the telescopic rod 35 to move, and the upper and lower sets of sliding rods 32 are pulled synchronously. When the sliding rod 32 moves, the two sets of positioning rings 34 are pulled horizontally on the inner wall of the guide groove of the fixing seat 31 through the hinge rod 33, so that the two sets of positioning rings 34 are close to each other, and the hydrogen storage tanks of different heights are pressed and fixed. The insertion rod 39 is aligned with the through hole at the corresponding position on the T-shaped rod 36, and the insertion rod 39 is released. The insertion rod 39 is automatically reset under the elastic action of the limit spring 38 and inserted into the through hole, and the sliding seat 37 drives the telescopic rod 35 to move so that the two sets of positioning rings 34 are fixed according to the position after clamping and positioning the hydrogen storage tanks of different thicknesses.

[0040] When the positioning ring 34 presses the hydrogen storage tank, the contact plate 8 contacts the outer wall of the hydrogen storage tank, and the connecting spring 7 applies elastic support to the contact plate 8. When the entire tank is subjected to a collision, the elastic effect of the connecting spring 7 can cushion the impact on the hydrogen storage tank and avoid damage to the outer surface of the hydrogen storage tank. At the same time, the contact plate 8 is made of rubber material, which can also reduce damage to the outer shell of the hydrogen storage tank.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
