[0002] Smart forklifts are a new generation of warehousing and logistics equipment that integrates IoT, positioning and navigation, sensor perception and automated control technologies. They can improve warehousing efficiency and reduce labor costs. However, for manually operated smart forklifts, in order to avoid visual errors and fatigue caused by operators looking up, and to reduce the safety risks of goods slipping and shelf collisions, a laser positioning display mechanism for fork height must be installed on the smart forklift to assist in operation.

[0003] In warehouse operations, laser positioning display mechanisms for fork height are often located in high-temperature, dusty, and poorly ventilated environments.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Please refer to Figures 1-4 and Figures 6-8As shown, the present invention provides a technical solution: a laser positioning display mechanism for the height of a smart forklift fork, including a positioning display mechanism 1. The positioning display mechanism 1 includes a housing 101, an adjustable display screen 102 mounted on the upper side of the housing 101, a mounting frame 103 arranged around the housing 101, two sets of adjustable brackets 104 mounted on the mounting frame 103, and a fixed rod 105 rotatably connected between opposite ends of each set of adjustable brackets 104. A laser ranging sensor 106 is fixed between the outer surfaces of the two fixed rods 105. A cover 107 is mounted at the back opening of the housing 101, and multiple hexagonal posts 108 are fixed on the surface of the cover 107. A control board 109 is mounted between the same ends of the multiple hexagonal posts 108. The control board 109 and the multiple hexagonal posts 108 are all located within the housing 101. Inside the housing 101, a perforated partition 110 is fixed inside. A main fan 111 is installed on the surface of the perforated partition 110. The air outlet of the main fan 111 is aligned with a pre-drilled hole on the perforated partition 110. Multiple control buttons 112 and connectors 116 are installed on the inner wall of the housing 101. The control end of each control button 112 and the connection end of each connector 116 can move through the inner wall of the housing 101. The inner wall of the housing 101 has a pre-drilled mounting hole 113, and a perforated plug 114 is installed inside the mounting hole 113. An alarm 115 is installed on the top of the inner wall of the housing 101, and the alarm end of the alarm 115 can move through the top of the inner wall of the housing 101. A filter 117 is installed at the top air inlet of the housing 101. A wireless transmitter 118 is installed on the connection end of the connector 116.

[0023] In this embodiment, when the forks of the smart forklift move the goods upwards, the laser rangefinder 106 measures the distance between the forks and the ground in real time. Each detected distance value is wirelessly transmitted to the control board 109 via the wireless transmitter 118 and connector 116. Upon receiving the distance value, the control board 109 compares it with a pre-set distance threshold and also transmits the received distance value to the adjustable display screen 102 for display on its screen for the driver's viewing. When the distance value received by the control board 109 is lower than the pre-set distance threshold, the control board 109 will not report the issue. The alarm 115 issues an alarm command and simultaneously transmits the detected results to the adjustable display screen 102 in real time for display. When the distance value received by the control board 109 is the same as the distance threshold preset by the control board 109, the control board 109 will issue an alarm command to the alarm 115 to remind the driver to stop the fork movement. At the same time, it will also transmit the detected results to the adjustable display screen 102 for display. The driver can also control the fork movement by observing the results on the screen. This method can avoid visual errors and fatigue caused by the operator looking up, and reduce the safety risks of goods slipping and rack collisions.

[0024] Example 2: According to Figures 1-9As shown, the positioning display mechanism 1 is equipped with an auxiliary mechanism 2. The positioning display mechanism 1 includes a housing 101, and the auxiliary mechanism 2 includes a compressed gas cylinder 201. The outlet of the compressed gas cylinder 201 is connected to an electric regulating valve 204, and the outlet of the electric regulating valve 204 is connected to a connecting pipe 205. The outlet of the connecting pipe 205 is connected to a nozzle 206. A mixing box 207 is arranged around the compressed gas cylinder 201. A temperature sensor 208 is threadedly connected to the outer wall of the mixing box 207 near the top. A perforated plate 210 is fixed in the middle of the interior of the mixing box 207. A cylindrical hole 211 is pre-set on the inner wall of the mixing box 207 near the bottom. An auxiliary fan 213 is installed on the outer wall of the mixing box 207. The outer surface of the auxiliary fan 213 is provided with a first... Two rectangular frames 214 are used. An air guide frame 215 is installed inside the second rectangular frame 214. Fixing blocks 216 are installed inside two grooves at one end of the second rectangular frame 214. A drive motor 217 is installed on the outer wall of the second rectangular frame 214. Multiple fixing rings 202 and multiple anti-slip pads 203 are provided on the outer surface of the compressed gas cylinder 201. The compressed gas cylinder 201 is fixed to the inner wall of the housing 101 by the fixing rings 202 and anti-slip pads 203. A nozzle 206 is threaded onto the outer wall of the mixing chamber 207 and is used to output compressed gas into the mixing chamber 207. The detection end of the temperature sensor 208 extends into the mixing chamber 207. Two symmetrical baffles 209 are fixed inside the mixing chamber 207 near the top. The auxiliary fan 213 and cylindrical hole 211 are used to draw away the mixed gas that has reached the mixing box 207. A first rectangular frame 212 is fixed to the outer wall of the mixing box 207. The auxiliary fan 213 is located inside the first rectangular frame 212 and between the inside of the second rectangular frame 214. The fixing block 216 and bearing are used to allow the air guide frame 215 to rotate on the second rectangular frame 214. The air guide frame 215 is used to change the gas delivery direction. The drive motor 217 is used to drive the air guide frame 215 to rotate. A partition plate 218 is added to the bottom of the inner wall of the housing 101. One end face and the top of the partition plate 218 are in contact with the inner wall of the housing 101. The mixing box 207 is added to the top of the inner wall of the housing 101. The interior of the mixing box 207 is connected to the air inlet at the top of the inner wall of the housing 101. The first rectangular frame 212 is fixed to the outer wall of the housing 101. A mounting bracket 103 is arranged around the housing 101. Two sets of adjustable brackets 104 are mounted on the mounting bracket 103, and a fixed rod 105 is rotatably connected between opposite ends of each set of adjustable brackets 104. A laser rangefinder sensor 106 is fixed between the outer surfaces of the two fixed rods 105. A cover 107 is installed at the back opening of the housing 101. Multiple hexagonal posts 108 are fixed on the surface of the cover 107. A control board 109 is installed between the same ends of the multiple hexagonal posts 108. A perforated partition 110 is fixed inside the housing 101. A main fan 111 is installed on the surface of the perforated partition 110. Multiple control buttons 112 and connectors 116 are installed on the inner wall of the housing 101.A filter 117 is installed at the top air inlet of housing 101, and a wireless transmitter 118 is installed at the connection end of connector 116. This method can improve heat exchange efficiency, thereby extending the service life of the fork height laser positioning display mechanism.

[0025] In this embodiment, when the laser rangefinder 106 starts detecting data, the control board 109 will activate the main fan 111. The activated main fan 111, through the filter 117, mixing chamber 207, cylindrical hole 211, pre-drilled holes on the perforated partition 110, through holes on the perforated plate 210, the first rectangular frame 212, and the second rectangular frame 214, filters the ambient air before drawing it in. The flowing air then carries away the heat generated by the electronic components on the control board 109. The heated air then passes through the gap between the partition 218 and the housing 101, is drawn away by the activated main fan 111, and passes through the pre-drilled holes on the perforated partition 110 and the housing 101. The air is vented into the environment through the pre-reserved exhaust vent. While the laser rangefinder 106 is detecting data in real time, the temperature sensor 208 is also detecting the temperature of the air entering the mixing chamber 207 in real time. The detected temperature value is wirelessly transmitted to the control board 109 via connector 116 and wireless transmitter 118. Upon receiving the temperature value, the control board 109 compares it with a preset temperature threshold. If the detected temperature value is lower than the preset temperature threshold, the control board 109 will not activate the auxiliary fan 213, drive motor 217, or electric regulating valve 204. When the preset temperature threshold of the control board 109 is high, the control board 109 will start the main fan 111 and the drive motor 217, and simultaneously open the electric regulating valve 204 to the preset opening degree. When the electric regulating valve 204 is open, the dry compressed air released from the compressed gas cylinder 201 will pass through the inside of the electric regulating valve 204, first to the inside of the connecting pipe 205, then to the inside of the nozzle 206, and then sprayed out from its outlet into the inside of the mixing box 207. At this time, the high-pressure gas sprayed out will experience a sudden pressure drop due to the throttling effect, and the distance between gas molecules will increase sharply, increasing the molecular potential energy. At this time, according to the law of conservation of energy, the molecular kinetic energy... The temperature of the air passing through the mixing chamber 207 will decrease rapidly. The cooled air will then pass through the through holes of the perforated plate 210, the interior of the cylindrical holes 211, and the interior of the second rectangular frame 214. When the low-temperature air reaches the interior of the second rectangular frame 214 and continues to be transported, the drive motor 217, which is started at this time, will cooperate with the second rectangular frame 214, the corresponding bearing, and all the fixing blocks 216 to drive the air guide frame 215 to rotate back and forth. The rotating air guide frame 215 blows the low-temperature air toward the surface of the control board 109. That is, the rapidly flowing low-temperature air is used to remove the heat generated by the electronic components on the control board 109 during operation. The above operation steps are then repeated until the air is discharged into the environment.

[0026] The overall effect and working principle of the mechanism are as follows: In use, first, rotate all the adjustable brackets 104 rotatably connected to both ends of each fixed rod 105 until they are level with the corresponding fixed rod 105. Then, pass both fixed rods 105 through the pre-drilled holes on the laser rangefinder sensor 106, and use the prepared nuts to fix the fixed rods 105 to the laser rangefinder sensor 106. Simultaneously, rotate all the adjustable brackets 104 back to their original positions and install them on the mounting bracket 103. Next, install the mounting bracket 103 on the forklift lifting mechanism of the smart forklift, ensuring that the emitting end of the laser rangefinder sensor 106 faces downwards towards the ground and can rise and fall synchronously with the forks. Then, using an accurate level and mounting bracket 103… Adjust all fixed rods 105 and all adjustable brackets 104 to ensure the laser rangefinder 106 is level. Once the laser rangefinder 106 is installed, install the housing 101 in a suitable position in the cab. At the same time, adjust the screen angle of the adjustable display 102. Then, connect the control board 109 to the power supply equipment on the smart forklift using the prepared cable and the plug with holes 114. Next, use the control button 112 and the control board 109 to set the distance threshold (distance between the ground and the forks), the temperature threshold (air temperature entering the mixing chamber 207), the valve opening degree of the electric regulating valve 204, and start the adjustable display 102. Then, open the valve of the compressed gas cylinder 201. When the forks of the smart forklift move the goods upwards, the laser range sensor 106 measures the distance between the forks and the ground in real time. Each detected distance value is wirelessly transmitted to the control board 109 via the wireless transmitter 118 and connector 116. Upon receiving the distance value, the control board 109 compares it with a pre-set distance threshold and also transmits the received distance value to the adjustable display screen 102 for display by the driver. When the distance value received by the control board 109 is lower than the pre-set distance threshold, the control board 109 will not send an alarm command to the alarm 115, but will still transmit the detection result to the adjustable display screen 102 for display. When the distance value received by the control board 109 is the same as the pre-set distance threshold, the control board 109 will send an alarm command to the alarm 115 to remind the driver. The driver pauses the fork movement and transmits the detected results to the adjustable display screen 102, where they are displayed. The driver can then control the fork movement by observing the results on the screen. Simultaneously, when the laser rangefinder 106 starts detecting data, the control board 109 activates the main fan 111. The activated main fan 111 filters the ambient air through the filter screen 117, mixing box 207, cylindrical hole 211, pre-drilled holes on the perforated partition 110, through holes on the perforated plate 210, first rectangular frame 212, and second rectangular frame 214. The air is then drawn in and the flowing air carries away the heat generated by the electronic components on the control board 109. The heated air then passes through the gap between the partition plate 218 and the housing 101, is drawn in by the activated main fan 111, and is discharged into the environment through the pre-drilled holes on the perforated partition 110 and the exhaust holes on the housing 101. While the laser rangefinder 106 is detecting data in real time, the temperature sensor 208 is also detecting the air temperature entering the mixing chamber 207 in real time. The detected temperature value is wirelessly transmitted to the control board 109 via connector 116 and wireless transmitter 118. Upon receiving the temperature value, the control board 109 compares it with a preset temperature threshold. If the detected temperature value is lower than the preset threshold, the control board 109 will not activate the auxiliary fan 213, drive motor 217, or electric regulating valve 204. If the detected temperature value is higher than the preset threshold, the control board 109 will activate the main fan 111 and drive motor 217, and simultaneously open the electric regulating valve 204 to a preset opening degree. When the electric regulating valve 204 is open, the dry compressed air released from the compressed gas cylinder 201 will pass through the open valve. First, the gas is fed into the connecting pipe 205, then into the nozzle 206, and finally sprayed out from its outlet into the mixing chamber 207. At this time, the high-pressure gas will experience a sudden pressure drop due to the throttling effect, and the distance between gas molecules will increase sharply, increasing the molecular potential energy. According to the law of conservation of energy, the molecular kinetic energy will decrease accordingly. At this time, the temperature of the air passing through the mixing chamber 207 will drop rapidly. Then, the cooled air will pass through the through holes of the perforated plate 210, the interior of the cylindrical holes 211, and the interior of the second rectangular frame 214. When the low-temperature air reaches the interior of the second rectangular frame 214 and continues to be fed, the drive motor 217, which is started at this time, will drive the air guide frame 215 to rotate back and forth through the second rectangular frame 214, the corresponding bearing, and all the fixing blocks 216. The rotating air guide frame 215 blows the low-temperature air onto the surface of the control board 109, that is, the rapidly flowing low-temperature air is used to remove the heat generated by the electronic components on the control board 109 during operation. Then, the above operation steps are repeated until the air is discharged into the environment.
