When in use, please refer to Figure 1-9. The user drives the car body 1. When there are obstacles around the car body 1 or the car body 1 needs to reverse and is about to collide, the distance detector starts to work at this time and transmits the signal to the judgment module, the judgment module determines the distance. When the impending collision distance is reached, the judgment module transmits the signal to the audio alarm module and the cloud platform. The car body 1 emits an alarm sound, and the cloud platform collects the signal and then transmits the signal to the PLC controller. , causing the drive motor 42 in the camera assembly 4 to start operating, thereby causing the drive motor 42 to drive the drive disc 43 to rotate. Finally, the drive disc 43 drives the self-adjusting assembly 44 on the top, the connecting seat 45 and the camera 49 to rotate, causing the camera 49 to rotate. Rotate to the area of imminent collision;

Then the camera module transmits the signal to the top of the touch panel 3 to display the image of the obstacle. The driver judges and controls the vehicle body 1 to keep the vehicle body 1 away from the obstacle area. Once the camera component 4 is rotated by human external force, first the camera 49 is stressed and drives the connecting base 45 to rotate, so that the connecting rod 44112 and the clamping ball 44109 at the bottom of the connecting base 45 are forced to rotate in the direction of the connecting base 45. At this time, two arc-shaped limiting plates are wrapped on the outer wall of each clamping ball 44109. 44110 begins to receive force and causes the two arc-shaped limiting plates 44110 to move away from each other, causing the two arc-shaped limiting plates 44110 to lose their position on the stuck ball 44109, and finally the first outer ring 441 loses its position on the bottom of the connecting seat 45 limit;

After losing the restricting force, the second constant pressure rod 44205 begins to stretch to restore pressure, and lifts the connecting seat 45 upward, so that the connecting seat 45 drives the connecting rod 44112 and the clamping ball 44109 to move upward, and finally from the slot on the top of the first outer ring 441 When the stuck ball 44109 moves upward, the first constant pressure rod 44101 begins to stretch and restore pressure, thus pushing the pressure plate 44102, the guide rod 44103 and the guide wheel 44104 to move upward. At this time, the pull rope 44105 loses its tension. , thereby restoring the elastic force of the first spring 44108 and pushing the limit block 44107 downward, limiting the top of each set of arc-shaped limit plates 44110 that are rotated in opposite directions to prevent the arc-shaped limit plates 44110 from being restored by the force of the coil spring;

After the connecting seat 45 is separated from the self-adjusting assembly 44, even if the camera 49 is rotated by external force, the connecting seat 45 will only drive the second constant pressure rod 44205 and the inner disk 44202 to rotate. When the inner disk 44202 rotates, it is affected by the second spring. 44203 The elastic bump 44204 can snap into the corresponding groove of the second outer ring 442 during rotation. On the one hand, when the inner disk 44202 snaps with the second outer ring 442, it can follow the output of the drive motor 42. The shaft rotates, and the camera 49 can be manually rotated to rotate the inner disk 44202 without affecting the rotation of the output shaft of the drive motor 42, preventing the power of the drive motor 42 from being affected and burning, and each groove position is consistent with each slot position. Correspondingly, it is convenient for the user to depress the camera 49 so that each clamping ball 44109 can be re-locked into the corresponding first outer ring 441 slot, completing the clamping of the clamping balls 44109, so that the self-adjusting assembly 44 can be restored.

To sum up, this electric forklift working condition visualization system based on feed transfer, by setting up the camera 49 and the distance detector controlled by the cloud platform signal on the vehicle body 1, makes it possible to detect obstacles when the vehicle body 1 is moving. When an object is about to collide or when the car body 1 is reversing and the driver cannot observe the collision in the blind spot, an alarm sound can be sounded through the distance detector and the image collected by the camera 49 can be presented on the touch panel to facilitate the driver's observation. and operating the vehicle body 1, avoiding the risk of collision. By setting the camera assembly 4, when the vehicle body 1 encounters an obstacle, the camera 49 can not only be controlled by the cloud platform, thereby starting the driving motor 42 to operate, thereby causing the camera 49 to rotate Obtaining the obstacle image at the corresponding angle also enables when the camera 49 is rotated by human external force, the connection base 45 connected to the bottom of the camera 49 can be separated from the camera assembly 4, so that it can not only rotate with the power of the drive motor 42, but also be rotated by human external force. Rotate to prevent the power of the driving motor 42 from being affected by artificial rotation of the camera 49, causing damage to the driving motor 42, and to protect the entire camera assembly 4 from being damaged by artificial external forces and to work normally and efficiently.
