Particularly, when the roller 104a-1 encounters a recessed road surface, the supporting arm 104a is driven to slightly deflect, the supporting arm 104a in a deflected state presses the damper 104b to deform itself, and the supporting arm 104a has a certain buffering effect through the damper 104 b.

Example 4

Referring to fig. 1 to 6, a fourth embodiment of the present invention is based on the previous embodiment, except that an emergency measure is provided, that is, when the electric cabinet is impacted, the heat dissipation channel is closed to protect the electronic components in the mounting cylinder 101 as much as possible.

Specifically, a bearing for supporting the rotary drum 201 to rotate is arranged on the outer wall of the installation cylinder 101, a protection plate 202 is movably connected to the outer wall of the rotary drum 201 through a rotating shaft, and a torsion spring is arranged at the joint of the protection plate 202 and the rotating shaft of the rotary drum 201; wherein, because the protection plate 202 has a certain radian, this just makes through the setting of protection plate 202, can make rotary drum 201 will receive the influence of heat dissipation fan, and drives rotary drum 201 and slowly rotate to optimize the radiating effect in the installation barrel 101.

The clearance between guard plate 202 and the outer wall of rotary drum 201 is buffering passageway 202c, and the one end of guard plate 202 is conflict end 202a, and the outer wall of guard plate 202 is equipped with bolster 203, and the outer wall of guard plate 202 has seted up buffer tank 202b. The protection plate 202 not only can drive the drum 201 to rotate, but also can provide a certain buffer, that is, when the impact is applied by the impact object, the impact force directly acts on the outside of the protection plate 202, the protection plate 202 deflects, and the impact force is digested by the cooperation of the buffer channel 202c and the buffer member 203.

An interlayer 101b communicated with the first heat dissipation channel 101a is arranged in the mounting cylinder 101, and a blocking plate 101b-1 for closing the first heat dissipation channel 101a is rotatably arranged in the interlayer 101 b; an emergency assembly 300 is also provided outside the mounting cylinder 101. The plugging plate 101b-1 is an arc-shaped plate, and the number of the plugging plate corresponds to that of the first heat dissipation channels 101 a.

The emergency assembly 300 includes an emergency ring 301 rotatably disposed outside the mounting cylinder 101, and one end of the plugging plate 101b-1 extends outside the mounting cylinder 101 and is connected to the emergency ring 301. This means that when the emergency ring 301 rotates, the plugging plate 101b-1 is driven to rotate, so as to close the first heat dissipation channel 101a, and slight resistance exists in the emergency ring 301 during the rotation process (the prior art is fully described and not described herein too much), which is also for avoiding the occurrence of false slipping of the emergency ring 301.

The emergency ring 301 is provided with a connecting channel 301a near one end of the protection plate 202, and an interference groove 301a-1 capable of being matched with the interference end 202a is formed in the inner wall of the connecting channel 301 a. When the abutting end 202a enters the abutting groove 301a-1, i.e. the protection plate 202 will drive the emergency ring 301 to rotate.

In summary, in daily cases, the heat dissipation fan introduces external air into the installation cylinder 101, and at this time, due to the arc design of the protection plate 202, the hot air is discharged through each heat dissipation channel and gives the protection plate 202a deflecting force, so as to drive the installation cylinder 101 to rotate at a low speed.

While the connection passage 301a in the emergency ring 301 is used to support rotation of the shield plate 202 in a daily case for assisting a heat radiation work, when the shield plate 202 is impacted, a deflection force is given to the drum 201 through the shield plate 202 to rotate at a high speed.

The protection plate 202 in the high-speed rotation state throws the abutting end 202a away from the rotary drum 201 and is engaged with the abutting groove 301a-1 to drive the emergency ring 301 to rotate, so that the first heat dissipation channel 101a is closed by the plugging plate 101b-1 to protect the barrel electronic components.

It should be noted that, to further optimize the plugging effect of the plugging plate 101b-1, two opposite magnets may be respectively disposed at one end of the plugging plate 101b-1 and one end of the first heat dissipation channel 101a, and when the plugging plate 101b-1 is about to close the first heat dissipation channel 101a, the plugging plate 101b-1 is fixed by the force of magnetic attraction.

Example 5

The fixing plate 203b is shown in the figure as having an arabic numeral "7". In the sliding connection process of the sliding rod 203b-1, the sliding rod 203b-1 is limited by the self structural characteristics of the fixed plate 203b, so as to avoid excessive displacement.

The end face of the sliding rod 203b-1 is provided with a second elastic piece 203b-3, and one end of the second elastic piece 203b-3 is connected with the inner wall of the box body 203 a; the outer wall of the fixed plate 203b is provided with a connection frame 203c, and the inner wall of the connection frame 203c is movably provided with a connecting rod 203c-1. The second elastic member 203b-3 is a compression spring connecting frame 203c for supporting the connecting rod 203c-1 for linear displacement.

The outer wall of the connecting rod 203c-1 is rotatably provided with a transmission rod 203b-2, and one end of the transmission rod 203b-2 is connected with the outer wall of the sliding rod 203 b-1; one end of the connecting rod 203c-1 extends to the outside of the case 203a through the through-mounting hole 203a-1, and is provided with a buffer plate 203d, and the outer wall of the buffer plate 203d is provided with a washer 203d-1 made of a rubber material. The cushion ring 203d-1 of the cushioning material can deform to a certain extent under the influence of external force, and can achieve a certain cushioning effect through the deformation of the cushion ring itself (the characteristics of the rubber material are fully described in the prior art, and will not be repeated here).

In summary, according to the above embodiment, when the protection plate 202 is impacted and the buffer member 203 is required to provide buffering, the buffer plate 203d will contact the drum 201 and gradually approach the box 203a under the support of the link 203c-1, and at the same time, the acting force generated by the movement of the link 203c-1 will be transmitted to the slide rod 203b-1 through the transmission rod 203b-2, so as to compress the second elastic member 203b-3, thereby achieving a certain buffering effect.

It should be noted that, if the impact force is large, the buffer member 203 will bring about a certain "bouncing" effect to the protection plate 202, so as to accelerate the deployment thereof.
