[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-5 A shock-absorbing plate for a car trunk comprises four mounting tubes 1, the upper end of the mounting tube 1 is connected to the top of the trunk outside through a mounting frame 2, a connecting rod 3 is slidably installed inside the mounting tube 1, a mounting cavity is arranged inside the upper end of the connecting rod 3, and a damping slider 4 is slidably arranged inside the mounting cavity, the lower end of each connecting rod 3 extends to the outside of the mounting tube 1 and is commonly connected with a pad 5, a storage cavity is arranged inside the pad 5, and an extension plate 6 is slidably installed in the storage cavity, and a pressure regulating component and a monitoring component are respectively arranged on the upper end of the mounting tube 1.

[0024] Example 2

[0025] Reference Figure 1-5 , when other parts are the same as those in Example 1, the difference between this embodiment and Example 1 is that:

[0026] The pressure regulating component includes a threaded hole, an air inlet groove 7 and a sealing plug 8. The threaded hole is arranged on one side of the upper end of the mounting cylinder 1, and the sealing plug 8 is installed at the end of the threaded hole away from the interior of the mounting cylinder 1. The air inlet groove 7 is arranged on the side of the threaded hole at one end of the sealing plug 8. The arrangement of the pressure regulating component is convenient for adjusting the internal air pressure of the mounting cylinder 1, so as to facilitate personnel to release the extension plate 6; the monitoring component includes a placing cylinder 9, a tension spring 10 and a piston 11. The piston 11 is arranged in the middle of the placing cylinder 9, and the tension spring 10 is arranged at one end of the placing cylinder 9 away from the mounting cylinder 1. The two ends of the tension spring 10 are respectively connected to the piston 11 and the cylinder body of the placing cylinder 9. The cylinder body of the placing cylinder 9 is a transparent cylinder. The arrangement of the monitoring component is convenient for monitoring the internal gas pressure of the mounting cylinder 1, so that personnel can conveniently judge whether the internal air pressure of the mounting cylinder 1 is within an appropriate range through the monitoring component, so as to timely adjust the internal pressure of the mounting cylinder 1, thereby avoiding the phenomenon of excessive pressure or insufficient pressure.

[0027] The outer ring surface of the placement tube 9 is provided with a plurality of scale patterns, and the scale patterns are provided with eye-catching colors for identification. The setting of the scale patterns makes it easier for personnel to more accurately judge the internal pressure of the installation tube 1; a breathable dust-proof cotton plug 12 is provided at one end of the placement tube 9 away from the installation tube 1, and the dust-proof cotton plug 12 and the placement tube 9 can be disassembled. The setting of the dust-proof cotton plug 12 is convenient to prevent external dust from entering the placement tube 9 and interfering with the movement of the piston 11; a screw hole is provided at the upper end of the mounting frame 2, and the lower end of the mounting frame 2 is connected to the mounting tube 1 through a pipe hoop. The setting of the pipe hoop facilitates the connection between the mounting frame 2 and the mounting tube 1; contact strips 13 are provided at both ends of the lower surface of the pad 5, and the contact strip 13 is elastic. The setting of the contact strip 13 makes it convenient for the pad 5 and the bottom surface of the trunk to still have a certain degree of shock-absorbing effect when the pressure between the installation tube 1 and the connecting rod 3 is damaged and lost.

[0028] Principle and advantages of use: During use of the utility model, the four mounting cylinders 1 are mounted on the top of the external trunk through the mounting frame 2, and the pad 5 is located at the bottom of the trunk and connected to the connecting rod 3 at four corners, so that people can place luggage and other items on the upper surface of the pad 5. During the driving of the vehicle, when the vehicle is bumpy, the pad 5 drives the object to shake up and down. In this process, the pad 5 drives the connecting rod 3 to move up and down. When the connecting rod 3 moves upward, the gas inside the mounting cylinder 1 is compressed to generate positive pressure to resist the upward kinetic energy of the connecting rod 3. When the connecting rod 3 moves downward, the internal gas storage space of the mounting cylinder 1 increases, that is, the internal air pressure of the mounting cylinder 1 drops to negative pressure, so that the internal gas pressure of the mounting cylinder 1 forms an attraction on the connecting rod 3, thereby resisting the downward movement of the connecting rod 3, that is, a pneumatic shock absorbing assembly is formed between the mounting cylinder 1 and the connecting rod 3, thereby having a shock absorbing effect on the pad 5 and the objects placed thereon, that is, avoiding the phenomenon that the objects are damaged by shock, such as eggs, fruits and other fragile items.

[0029] At the same time, in the above process, since the damping slider 4 is provided inside the connecting rod 3, that is, when the connecting rod 3 moves up and down, the damping slider 4 provides a damping effect thereto, so that the connecting rod 3 shakes less during shock absorption, thereby avoiding the phenomenon that the object shakes up and down significantly after shock absorption; and since an extension plate 6 is provided inside the pad 5, that is, when people drive for a picnic, they can take out the sealing plug 8, and then pull the pad 5 upward until the pad 5 is higher than the bottom surface of the trunk, and then pull the extension plate 6 out from the inside of the pad 5 until most of the extension plate 6 is located outside the pad 5. At this time, the overall use area of ​​the pad 5 is increased, and when the extension plate 6 is not needed, the extension plate 6 can be directly stored in the pad 5.

[0030] It should be further explained that the setting of the pressure regulating component is convenient for adjusting the internal air pressure of the mounting tube 1, so as to facilitate personnel to release the extension plate 6; the setting of the monitoring component is convenient for monitoring the internal gas pressure of the mounting tube 1, so that personnel can conveniently determine whether the internal air pressure of the mounting tube 1 is within an appropriate range through the monitoring component, so as to timely adjust the internal pressure of the mounting tube 1, so as to avoid the phenomenon of excessive pressure or insufficient pressure; the setting of the dustproof cotton plug 12 is convenient for preventing external dust from entering the placement tube 9 and interfering with the movement of the piston 11; the setting of the pipe clamp is convenient for connecting the mounting frame 2 and the mounting tube 1; the setting of the contact strip 13 is convenient for when the pressure between the mounting tube 1 and the connecting rod 3 is damaged and lost, there is still a certain degree of shock-absorbing effect between the pad 5 and the bottom of the trunk.

[0031] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
