The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0030] A vehicle-mounted hydrogen storage tank stabilizing device, such as Figures 1 - 3As shown, it includes a hydrogen storage tank 0, a base plate 1, a spring support 2, a side frame 3, a compression spring 4, a fixed clamp frame 5, a rear top mechanism 6 and a front limiting mechanism 7. The spring support 2 is connected to the upper middle side of the base plate 1. The spring support 2 is an arc structure and a buffer rubber ball is provided on the contact surface with the hydrogen storage tank 0, which can protect the hydrogen storage tank 0 to the maximum extent and prevent the vehicle-mounted hydrogen storage tank 0 from being worn. A plurality of side frames 3 are connected to the top of the base plate 1. The upper parts of the side frames 3 are all slidably connected to the fixed clamp frames 5. The fixed clamp frames 5 are connected to the adjacent side frames 3 with a plurality of compression springs 4. The hydrogen storage tank 0 is placed on the spring support 2. A rear top mechanism 6 for limiting the rear of the hydrogen storage tank 0 is provided on the upper rear side of the base plate 1. A front limiting mechanism 7 for limiting the front of the hydrogen storage tank 0 is provided on the upper front side of the base plate 1.

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, the rear top mechanism 6 includes a vertical spring assembly 61, a rear frame 62, a flight spring 63, a side wall buffer plate 64 and a thrust valve 65. The upper rear side of the bottom plate 1 is connected to the vertical spring assembly 61, the upper part of the vertical spring assembly 61 is slidably connected to the rear frame 62, the rear frame 62 is internally slidably connected to the side wall buffer plate 64, a plurality of flight springs 63 are connected between the side wall buffer and the rear frame 62, and the left and right sides of the lower part of the side wall buffer plate 64 are connected to the thrust valve 65. The hydrogen storage tank 0 moves backward on the spring support 2, squeezing the side wall buffer plate 64 so that the side wall buffer plate 64 slides on the rear frame 62 to compress the flight spring 63. The flight spring 63 performs front and rear buffering protection on the hydrogen storage tank 0 through the side wall buffer plate 64. At the same time, the rear frame 62 cooperates with the vertical spring assembly 61 to perform up and down vibration buffering on the hydrogen storage tank 0.

[0032] like Figure 1 , Figure 2 and Figure 5 As shown, the front limit mechanism 7 includes a latch seat 71, a double-ear plate 72, a locking arc 73, a lifting assembly 74, a lower round frame 75, a lifting ear 76, an upper round frame 77 and a ball plate 78. The latch seat 71 is connected to the upper side of the front of the bottom plate 1, the double-ear plate 72 is rotatably connected to the latch seat 71, the locking arc 73 is rotatably connected to the double-ear plate 72, the lifting assembly 74 is slidably connected to the upper sides of the left and right parts of the double-ear plate 72, the lower round frame 75 is connected between the upper parts of the lifting assembly 74, and the lifting ears 76 are slidably connected to the left and right parts of the lower round frame 75 An upper round frame 77 is connected between the upper parts of the lifting ears 76, and a ball plate 78 is rotatably connected to the right sides of the upper round frame 77 and the lower round frame 75. The double-ear plate 72 can be rotated and opened and closed on the latch seat 71, which is convenient for placing and taking the hydrogen storage tank 0. The locking arc 73 can fix the double-ear plate 72. The rotation of the double-ear plate 72 can drive the lower round frame 75 and the upper round frame 77 to move together through the lifting component 74. The lower round frame 75 can slide up and down on the double-ear plate 72 under the action of the lifting component 74 to adapt to the height of the hydrogen storage tank 0.

[0033] When it is necessary to stabilize the on-vehicle gas storage tank, this device can be used. First, place this device in the vehicle installation area and fix the bottom plate 1. Then, place the hydrogen storage tank 0 on the spring support 2. When the hydrogen storage tank 0 is placed on the spring support 2, first rotate and open the double-ear plate 72. The double-ear plate 72 can rotate and open on the pin seat 71, which is convenient for placing and taking the hydrogen storage tank 0. The locking arc 73 can fix the double-ear plate 72. When the double-ear plate 72 rotates, it can drive the lower circular frame 75 and the upper circular frame 77 to move together through the lifting component 74. The lower circular frame 75 can slide up and down on the double-ear plate 72 under the action of the lifting component 74 to adapt to the height of the hydrogen storage tank 0. After the hydrogen storage tank 0 is placed, rotate and close the double-ear plate 72, and fix the double-ear plate 72 through the locking arc 73. At the same time, the rear part of the hydrogen storage tank 0 squeezes the side wall buffer plate 64, so that the side wall buffer plate 64 slides on the rear frame 62 and compresses the engine flight spring 63. The engine flight spring 63 buffers and protects the hydrogen storage tank 0 from front and back through the side wall buffer plate 64. At the same time, the rear frame 62 cooperates with the vertical spring component 61 to buffer the up and down vibration of the hydrogen storage tank 0. Through the cooperation of the side wall buffer plate 64, the lower circular frame 75 and the upper circle, the front and back sides of the hydrogen storage tank 0 are limited and stabilized. When it is necessary to take out the hydrogen storage tank 0, unlock the locking arc 73 and rotate and open the double-ear plate 72. After the hydrogen storage tank 0 is taken out, the engine flight spring 63 rebounds and drives the side wall buffer plate 64 to reset. When the hydrogen storage tank 0 is placed, the spring support 2, the upper circular frame 77, the lower circular frame 75 and the side wall buffer plate 64 cooperate with each other to buffer and protect the hydrogen storage tank 0 during vehicle driving. Through the above cooperation of the side stand 3, the side wall buffer plate 64, the lower circular frame 75 and the upper circle, and the auxiliary support by the spring support 2, the effect of buffering and protecting the on-vehicle hydrogen storage tank 0, reducing vibration and wear, and improving the safety of the on-vehicle hydrogen storage tank 0 can be achieved.

[0034] Such as Figure 1 , Figure 2 and Figure 6As shown in the figure, it further includes a side clamping mechanism 8 for clamping the side of the hydrogen storage tank 0. The side clamping mechanism 8 includes a gear seat 81, a sliding seat 82, a transverse spring assembly 83, a side wheel arc clamp 84, a fixed inclined rail 85 and a rack group 86.

Fixed inclined rails 85 are connected to both the front and rear sides of the gear seats 81. The fixed inclined rails 85 are slidably connected to the adjacent sliding seats 82. The side wheel arc clamps 84 are in extrusion fit with the adjacent fixed inclined rails 85. Rack groups 86 are connected between the sliding seats 82 and the gear seats 81 and the spring support 2. The spring support 2 is extruded and moves downward by the gravity of the hydrogen storage tank 0. Through the mutual cooperation of the rack groups 86, the sliding seat 82 slides upward on the gear seat 81, driving the side wheel arc clamp 84 to slide upward along the fixed inclined rail 85 together. The side wheel arc clamp 84 slides on the sliding seat 82 under the guiding of the shape of the fixed inclined rail 85 and compresses the transverse spring assembly 83. The transverse spring assembly 83 enables the side wheel arc clamps 84 to always maintain an opposite clamping force to clamp and fix the hydrogen storage tank 0.

[0035] When using the side clamping mechanism 8 of this device, it can clamp the side of the hydrogen storage tank 0. The spring support 2 is extruded and moves downward by the gravity of the hydrogen storage tank 0. Through the mutual cooperation of the rack groups 86, the sliding seat 82 slides upward on the gear seat 81, driving the side wheel arc clamp 84 to slide upward along the fixed inclined rail 85 together. The side wheel arc clamp 84 slides on the sliding seat 82 under the guiding of the shape of the fixed inclined rail 85 and compresses the transverse spring assembly 83. The transverse spring assembly 83 enables the side wheel arc clamps 84 to always maintain an opposite clamping force to clamp and fix the hydrogen storage tank 0. When the spring support 2 returns upward, it drives the sliding seat 82 to reset downward through the rack group 86. Through the above operation that the spring support 2 controls the up and down movement of the sliding seat 82 through the rack group 86, enabling the sliding seat 82 to control the side wheel arc clamp 84 to clamp the side of the hydrogen storage tank 0, the effect of clamping the side of the hydrogen storage tank 0 and improving the safety of the in-vehicle hydrogen storage tank 0 can be achieved.

The motor group 96 includes a servo motor and a belt. A servo motor is connected to the lower right side of the lower part of the middle side stand 3. A belt is wound between the chuck 92 and the output shaft of the servo motor. When the spring support 2 is pressed downward by the hydrogen storage tank 0, the connecting shaft 94 is driven to move downward through the side support arm 93. The connecting shaft 94 moves downward and is inserted into the middle circular support 91, driving the inclined chuck 95 to move together. When the connecting shaft 94 moves downward to be in meshing butt joint with the chuck 92, the motor group 96 is started. The motor group 96 drives the connecting shaft 94 to rotate through the chuck 92. The rotation of the connecting shaft 94 causes the position of the inclined chuck 95 to change, forming a clamping position with the middle circular support 91 to restrict and fix the spring support 2. When the spring support 2 needs to be released again, the motor group 96 is controlled to drive the chuck 92 to drive the connecting shaft 94 to rotate.

[0037] Using the side locking mechanism 9 of the present device, the side surface of the spring support 2 can be locked.

When the connecting shaft 94 moves downward to be in meshing butt joint with the chuck 92, the motor group 96 is started. The motor group 96 drives the connecting shaft 94 to rotate through the chuck 92. The rotation of the connecting shaft 94 causes the position of the inclined chuck 95 to change, forming a clamping position with the middle circular support 91 to restrict and fix the spring support 2. When the spring support 2 needs to be released again, the motor group 96 is controlled to drive the chuck 92 to drive the connecting shaft 94 to rotate. After the connecting shaft 94 is reset, the motor group 96 can be turned off. Through the above operation of the connecting shaft 94 and the chuck 92 cooperating to drive the side support arm 93 to press the support plate, the side surface of the spring support 2 can be locked, achieving the effect of improving the safety of the vehicle-mounted hydrogen storage tank 0.
