[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Example, see Figure 1-Figure 6 An intelligent freight elevator with an automatic infrared induction control device outside the car door, comprising a bottom plate 1. The upper surface of the bottom plate 1 is fixedly connected with a freight elevator frame 2. A lifting platform 3 is slidably arranged inside the freight elevator frame 2. The lifting platform 3 is in a U-shaped structure. Hydraulic lifting rods 11 are fixedly installed on both the left and right sides of the freight elevator frame 2. The top ends of the telescopic rods of the two hydraulic lifting rods 11 are fixedly connected with a lifting frame 15. Two position-symmetrical limit sliding rails 17 are fixedly connected to both side surfaces of the freight elevator frame 2. The lifting frame 15 is slidably connected to the surfaces of the limit sliding rails 17.

[0034] Two guiding sprockets 6 are fixedly installed on the lower surface of the lifting frame 15. A lifting chain 7 is sleeved on the surface of the guiding sprocket 6. One end of the lifting chain 7 is fixedly connected to the bottom of the freight elevator frame 2, and the other end of the lifting chain 7 is fixedly connected to both sides of the lifting platform 3.

[0035] It should be noted that by arranging the hydraulic lifting rods 11 on both sides of the freight elevator frame 2, the two lifting frames 15 can be driven by the hydraulic lifting rods 11 to move up and down in the two limit sliding rails 17 of the freight elevator frame 2. Then, the guiding sprockets 6 and the lifting chain 7 are used to drive the lifting platform 3 to move up and down inside the freight elevator frame 2, realizing the smooth rise and fall of the lifting platform 3.

[0036] Furthermore, a rectangular installation hole 8 is opened on the upper surface of the lifting platform 3. A plurality of power transmission rollers 9 are rotatably arranged on the inner wall of the rectangular installation hole 8. It should be noted that by arranging a plurality of power transmission rollers 9 on the surface of the lifting platform 3 of the freight elevator, the lifting platform 3 can be docked with external power transmission equipment, enabling the external power transmission equipment to directly transport the goods to the surface of the power transmission rollers 9 on the surface of the lifting platform 3. Then, when unloading, the power transmission rollers 9 are used to transfer the goods out of the lifting platform 3, thus realizing the self-loading and unloading of goods and enabling the lifting platform 3 to achieve the effect of intelligent automatic loading and unloading of goods.

[0037] Supporting flat plates 10 are rotatably connected to the left and right inner side surfaces of the lifting platform 3 through hinges. The two supporting flat plates 10 are symmetrically distributed on the surface of the lifting platform 3 left and right. A release mechanism 4 is arranged on the side of the lifting platform 3. The release mechanism 4 is used to lock and release the supporting flat plates 10. An installation cross frame 12 is fixedly connected to the front of the freight elevator frame 2. A plurality of infrared sensors 13 are fixedly installed on the surface of the installation cross frame 12. A controller and a buzzer alarm are respectively arranged on the surface of the installation cross frame 12. The controller is electrically connected to the infrared sensors 13 and the buzzer alarm respectively.

[0038] It should be noted that, by arranging an infrared sensor 13 on the surface of the freight elevator frame 2, when the infrared sensor 13 detects that someone is approaching the entrance of the lifting platform 3, not only can a buzzer alarm be issued to prevent people from using the lifting platform 3 together with goods, but the supporting plate 10 can also be lowered through the release mechanism 4, thereby making it easier for people to use the freight elevator.

[0039] Furthermore, the lower surface of the supporting plate 10 is rotatably connected to two limit support blocks 18, the lower surface of the limit support blocks 18 is fixedly connected to a rubber buffer pad, the lower surface of the limit support blocks 18 overlaps the upper surface of the lifting platform 3, and the limit support blocks 18 are used to support the bottom of the supporting plate 10.

[0040] It is worth mentioning that by arranging two foldable support plates 10 on the inner side of the lifting platform 3, when the power transmission rollers 9 are not needed, or the staff needs to use the lifting platform 3, the two support plates 10 can be placed flat on the surface of the lifting platform 3, and the limiting support blocks 18 at the bottom of the support plates 10 can be used to limit the bottom of the support plates 10, thereby blocking the power transmission rollers 9 on the surface of the lifting platform 3, so that the surface of the lifting platform 3 remains flat, which is convenient for people to board and allows the lifting platform 3 to freely switch between different functions.

[0041] It should be noted that the release mechanism 4 includes a fixed shell 401 fixedly connected to both sides of the lifting platform 3, and a linkage motor 402 is fixedly connected to the lower surface of the fixed shell 401. The output shaft of the linkage motor 402 extends to the interior of the fixed shell 401 and is fixedly connected to a linkage screw rod 403. The surface of the linkage screw rod 403 is threadedly connected to an L-shaped locking plate 404.

[0042] It is worth noting that an unlocking hole is provided on the surface of the L-shaped locking plate 404, and the position of the L-shaped locking plate 404 corresponds to the supporting plate 10. A locking slot 14 is provided on the surface of the supporting plate 10. The position of the locking slot 14 corresponds to the L-shaped locking plate 404, and the size of the locking slot 14 matches the L-shaped locking plate 404. A strip guide hole 405 is provided on the side of the lifting platform 3, and the L-shaped locking plate 404 passes through the strip guide hole 405, and the L-shaped locking plate 404 is slidably connected to the inner wall of the strip guide hole 405.

[0043] The advantage of adopting the above structure is that, by arranging the release mechanism 4 on both sides of the lifting platform 3 and arranging the infrared sensor 13 at the entrance of the cargo elevator frame 2, when the infrared sensor 13 detects that someone is approaching the lifting platform 3, the linkage motor 402 of the release mechanism 4 can be started by the controller, so that the linkage motor 402 is used to drive the linkage screw rod 403 to rotate, and the linkage screw rod 403 drives the L-shaped locking plate 404 to move upward, so that the L-shaped locking plate 404 is removed from the locking slot 14 on the surface of the supporting plate 10, thereby releasing the limit on the supporting plate 10, and then the supporting plate 10 can be put down, and at the same time, a buzzer reminder is issued through the buzzer alarm, so as to achieve the effect of reminding the lifting platform 3 that prohibits the sharing of people and goods.

[0044] It should be noted that extension mechanisms 5 are provided at both the front and rear ends of the lifting platform 3 , and the extension mechanisms 5 are used to extend and expand the loading and unloading port of the lifting platform 3 . The extension mechanisms 5 include extension plates 501 rotatably connected to the front and rear surfaces of the lifting platform 3 .

[0045] Furthermore, the lower surface of the lifting platform 3 is fixedly connected to the limiting bottom shell 16, and the inner bottom wall of the limiting bottom shell 16 is fixedly installed with a dual-axis motor 502. The two output shafts of the dual-axis motor 502 are fixedly connected to the driving screw 503. The surface of the driving screw 503 is threadedly connected with a movable sleeve 504. The ends of the two movable sleeves 504 away from each other are rotatably connected to a movable push rod 505. The end of the movable push rod 505 away from the movable sleeve 504 is rotatably connected to the lower surface of the extension plate 501.

[0046] Furthermore, two limiting guide holes 506 are opened on the lower surface of the limiting bottom shell 16, and the inner wall of the limiting guide hole 506 is fixedly connected with a guide slide rod 507, and the surface sliding sleeve of the guide slide rod 507 is provided with a guide slider 508, and the upper surface of the guide slider 508 is fixedly connected to the bottom of the movable sleeve 504.

[0047] It is worth mentioning that by arranging extension mechanisms 5 at the front and rear ends of the lifting platform 3, when there is a certain distance or height difference between the lifting platform 3 and external equipment such as a conveyor belt or an unloading platform, the dual-axis motor 502 at the bottom of the lifting platform 3 can be used to drive the two driving screws 503 to rotate, thereby driving the two movable sleeves 504 to move, and at the same time the movable sleeves 504 drive the movable push rods 505 to move, and then the movable push rods 505 are used to drive the two extension plates 501 to expand a certain angle on both sides of the front end of the lifting platform 3, thereby filling and extending the gap or height difference between the lifting platform 3 and the external conveying equipment or the unloading platform, playing a role of expansion and extension, so that it is suitable for different usage environments and improves the application scope of the lifting platform 3.
