Description

Technical Field

[0001] The utility model belongs to the technical field of supporting and installing a vehicle hydrogen storage tank, and particularly relates to a supporting device for a vehicle hydrogen storage tank. Background Art

[0002] A vehicle hydrogen storage tank is a container for storing high-pressure hydrogen designed for vehicles. It is suitable for fuel cell vehicles (FCVs) and other vehicles that use hydrogen as a power source. This type of tank is usually made of high-strength composite materials (such as carbon fiber reinforced plastics, CFRP), and has the characteristics of lightweight, strong pressure resistance, and high safety. It can withstand the storage needs of high-pressure hydrogen in a vehicle-mounted environment, and has undergone rigorous design, manufacturing and testing to ensure that the hydrogen required by the fuel cell system can be reliably supplied during the vehicle's driving. The support device of the vehicle hydrogen storage tank is a fixed component installed on the vehicle structure. Its main function is to firmly and stably install the hydrogen storage tank in a predetermined position, while absorbing and transmitting various dynamic loads generated during the vehicle's driving, such as acceleration, braking, turning, bumps, etc. Caused by force and vibration, prevent the tank from being damaged due to uneven force or excessive vibration, and ensure the safe operation of the tank and the overall stability of the hydrogen system. If the existing vehicle hydrogen storage tank support device can only support and limit the left and right sides of the hydrogen storage tank, the hydrogen storage tank will move up and down.

[0003] For example, the utility model with announcement number CN217153819U discloses a support device for a vehicle hydrogen storage tank, and a clamp ring is fixedly provided on the top side of the slide plate. In the present patent scheme, the hydrogen storage tank is supported by two clamp rings approaching each other, and can only support and limit the left and right sides of the hydrogen storage tank, but cannot effectively support the upper end. Due to the lack of upper end support, the tank may cause large shaking or displacement in the vertical direction during driving of the vehicle, especially when encountering extreme situations such as undulating road surface, emergency braking or collision, increasing the risk of collision between the tank and surrounding structures, or causing uneven pressure distribution inside the tank, affecting the safety performance of the tank. Utility Model Content

[0004] In view of this, the utility model aims to solve the deficiencies in the prior art and provide a support device for a vehicle hydrogen storage tank, which can not only support and limit the left and right sides of the hydrogen storage tank, but also effectively support the upper end, thereby significantly improving the position stability of the storage tank during vehicle driving, reducing the shaking of the storage tank in all directions, and reducing the possibility of collision between the storage tank and other parts of the vehicle, thereby ensuring driving safety.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a supporting device for a vehicle hydrogen storage tank, comprising a mounting plate, a frame plate is arranged at the upper end of the mounting plate, clamping plates are slidably arranged in two sliding grooves opened at the upper end of the frame plate, the left and right positions of the two clamping plates correspond, buffer pads are respectively bonded to the relative inner sides of the two clamping plates, a driving mechanism is arranged at the lower ends of the two clamping plates, and an upper and lower supporting and limiting mechanism is arranged at the upper end of the frame plate, the driving mechanism comprises a rotating seat arranged at the lower ends of the two clamping plates, two connecting frames are rotatably arranged inside the two rotating seats, a rotating frame is rotatably arranged between two connecting frames adjacent to the left and right, two screw rods corresponding to the front and rear positions are rotatably arranged inside the frame plate, the thread directions of the two screw rods are opposite, and the two rotating frames are respectively threadedly connected to the adjacent screw rods. The bottom wall of the frame plate is provided with an electric drive unit for driving the screw rod to rotate, the electric drive unit includes a double-axis motor arranged on the bottom wall of the frame plate, the output shafts on the front and rear sides of the double-axis motor are respectively connected with the opposite inner ends of the two screw rods through couplings, the upper and lower support limit mechanisms include a fixed arc plate arranged on the upper end of the frame plate, a connecting plate is arranged at the upper end of the frame plate, two guide columns are arranged for sliding inside the connecting plate, a movable arc plate corresponding to the upper and lower positions of the fixed arc plate is arranged at the lower ends of the two guide columns, flexible contact pads are bonded to the inner arc walls of the movable arc plate and the fixed arc plate, a screw is connected to the internal threaded hole opened in the connecting plate, the lower end of the screw is rotatably connected to the upper end of the movable arc plate, the upper end of the screw is provided with an auxiliary component for assisting the rotation of the screw, and the auxiliary component includes a handwheel arranged at the upper end of the screw.

[0006] As a further improvement of the utility model, a control panel is arranged on the upper end of the mounting plate, and the dual-axis motor is electrically connected to the control panel.

[0007] As a further improvement of the utility model, mounting holes are provided at the four corners of the mounting plate.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0009] Firstly, by placing the hydrogen storage tank on a fixed arc plate, and then controlling the dual-axis motor to start running, the output shaft rotates to drive the screw rods on both sides to rotate. Since the screw rods on both sides have opposite thread directions, the rotating frames on both sides can be moved away from each other, so that the connecting frame inside them rotates and contracts, and then the clamping plates on the rotating seats on both sides are moved closer to each other under the restriction of the sliding groove to achieve clamping support for the left and right sides of the hydrogen storage tank. Then, by rotating the hand wheel, the screw rod rotates, driving the movable arc plate to move downward under the restriction of the guide column to cooperate with the fixed arc plate to achieve limited support for the upper and lower ends of the hydrogen storage tank. It can not only support and limit the left and right sides of the hydrogen storage tank, but also effectively support the upper end, which can significantly improve the position stability of the tank during vehicle driving, reduce the shaking of the tank in all directions, reduce the possibility of collision between the tank and other parts of the vehicle, and ensure driving safety.

[0010] Secondly, the buffer pads on the clamping plates on both sides can prevent the clamping plates from making hard contact with the hydrogen storage tank and causing damage to the hydrogen storage tank.

[0011] Thirdly, the flexible contact pads on the movable arc plate and the fixed arc plate can achieve flexible contact with the hydrogen storage tank, thereby avoiding the problem of damage to the outer surface of the hydrogen storage tank.

[0012] Fourthly, the support device can be quickly installed through the mounting holes on the mounting plate, which makes it convenient for personnel to install the support device on the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

Two screw rods 206 corresponding to the front and rear positions are rotatably arranged inside the frame plate 103. The thread directions of the two screw rods 206 are opposite. The two rotating frames 204 are respectively threadedly connected with the adjacent screw rods 206. An electric drive unit for driving the screw rods 206 to rotate is arranged on the bottom wall of the frame plate 103. The electric drive unit includes a dual-axis motor 205 arranged on the bottom wall of the frame plate 103. The output shafts on the front and rear sides of the dual-axis motor 205 are respectively connected to the relative inner ends of the two screw rods 206 through couplings.

[0021] like Figure 1 , 2 As shown in Figure 3, the upper and lower supporting and limiting mechanisms include a fixed arc plate 306 arranged at the upper end of the frame plate 103, a connecting plate 303 is arranged at the upper end of the frame plate 103, two guide columns 302 are slidably arranged inside the connecting plate 303, and a movable arc plate 304 corresponding to the upper and lower positions of the fixed arc plate 306 is arranged at the lower ends of the two guide columns 302, and flexible contact pads 305 are bonded to the inner arc walls of the movable arc plate 304 and the fixed arc plate 306, and a screw 307 is connected to the inner thread hole opened in the connecting plate 303, and the lower end of the screw 307 is rotatably connected to the upper end of the movable arc plate 304, and an auxiliary component for assisting the rotation of the screw 307 is arranged at the upper end of the screw 307, and the auxiliary component includes a handwheel 301 arranged at the upper end of the screw 307.
