[0022] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0023] See also Figures 1 to 5 The present embodiment provides a car loading and unloading platform, including: a loading and unloading part, the loading and unloading part includes a loading and unloading plate 3, a gas spring 303 and a supporting part, the upper end of the gas spring 303 is hinged to the loading and unloading plate 3, and the lower end is hinged to the supporting part, when the gas spring 303 is extended, the loading and unloading plate 3 is lifted up to form a ramp to connect the car and the ground for workers to load and unload goods, when the gas spring 303 is contracted, the loading and unloading plate 3 and the supporting part are folded up for easy storage, and the supporting part connects the loading and unloading plate 3 with the storage box 1, so that the loading and unloading plate 3 can be easily loaded into the storage box 1;

[0024] The storage part includes a storage box 1 and a tailgate 2. Both ends of the tailgate 2 are provided with baffle locks. The storage box 1 is fixedly installed at the bottom of the car to reasonably utilize the space for holding the unloading part. The tailgate 2 is installed on the lower side of the rear of the storage box 1 and can rotate around it. When the tailgate 2 is rotated upward and the baffle lock is locked, the storage box 1 is sealed, and the unloading part is inside. When the baffle lock is unlocked and the tailgate 2 is rotated downward, the storage box 1 is opened and the unloading part can be pulled out.

[0025] A plurality of hooks 306 are fixedly provided at the front end of the unloading board 3, which are used to hang the unloading board 3 on the hanging ears at the rear of the car. The two hooks 306 are all hung on the hanging ears to enhance the connection strength between the unloading board 3 and the car, prevent the unloading board 3 from falling off during the loading and unloading process, and improve the safety factor of the loading and unloading platform. A plurality of supporting legs 301 are fixedly provided under the unloading board 3. The two supporting legs 301 are respectively located on both sides of the unloading board 3 to connect the unloading board 3 with the support part.

[0026] The supporting part includes two vertical rods 302, a horizontal rod 304 and a roller 305. The rear end of the vertical rod 302 is connected to the support leg 301 and can rotate around it. The horizontal rod 304 is fixed to the front end of the two vertical rods 302. Both ends of the horizontal rod 304 protrude from the vertical rod 302. Both ends of the horizontal rod 304 are provided with rollers 305. The rollers 305 are rotatably connected to the horizontal rod 304. The rollers 305 roll to drive the unloading plate 3 to move in the storage box 1.

[0027] Two groove rails 101 are provided inside the storage box 1 to provide tracks for the roller 305 to roll. The length of the groove rails 101 is smaller than the length of the storage box 1, which restricts the roller 305 in the storage box 1 to prevent the roller 305 from completely sliding out of the storage box 1 and causing the storage part to fall to the ground.

[0028] The baffle lock includes a lock body and a limit block 205. The lock body includes a plurality of annular limit rings 202 and C-shaped limit rings 203, which limit the movement range of the latch 201 inside the lock body. The annular limit rings 202 and C-shaped limit rings 203 are both fixed above the front of the rear baffle 2.

[0029] A latch 201 is provided inside the annular limit ring 202 and the C-shaped limit ring 203. The latch 201 can move back and forth along the inner circle of the annular limit ring 202 and the C-shaped limit ring 203. A stopper 204 is provided behind the latch 201. The stopper 204 limits the maximum displacement of the latch 201 to prevent the latch 201 from being completely pulled out of the annular limit ring 202 and the C-shaped limit ring 203 and lost.

[0030] A notch is provided above the limit block 205 to facilitate the latch 201 to pass through the limit block 205. One end of the limit block 205 is fixed to the side wall of the storage box 1, and the notch of the limit block 205 protrudes out of the tail of the storage box 1. When the latch 201 is inserted into the notch, the baffle lock is locked and the storage box 1 is sealed. When the latch 201 is pulled out of the notch, the baffle lock is unlocked and the storage box 1 is opened.

[0031] Hold the latch 201 on one side of the rear baffle 2 and rotate it so that its top folding rod is at the same horizontal line with the notch of the C-shaped limit ring 203, and pull the latch 201 in the direction of the stop block 204. The end of the latch 201 is pulled out from the notch of the limit block 205, and the stop block 204 blocks the latch 201 from continuing to move forward, preventing the latch 201 from being pulled out of the annular limit ring 202, causing the latch 201 to be lost, so that the baffle lock loses its limiting effect on the rear baffle 2. Use the same method to open the baffle lock on the other side of the rear baffle 2, hold the rear baffle 2 with both hands and slowly move back. Under the action of its own weight, the rear baffle 2 rotates around its bottom edge and is finally hung on the bottom of the rear end of the storage box 1. The rear baffle 2 of the storage box 1 is opened, and the upper surface of the unloading plate 3 is pressed downward. , so that the gas spring 303 contracts, the unloading plate 3 and its lower bracket are folded together, and at the same time, the unloading plate 3 and the lower bracket are held, and the unloading plate 3 with one end of the hook 306 is inserted into the storage box 1 from the opened rear baffle 2, so that the rollers 305 at both ends of the cross bar 304 roll into the corresponding groove rails 101 respectively, and the unloading plate 3 is pushed into the storage box 1 to make it completely enter, and the rear baffle 2 is pulled and rotated upward to cover the rear end of the storage box 1, and the latch 201 is rotated so that the top folding rod and the gap of the C-shaped limit ring 203 are at the same horizontal line, and the latch 201 is pushed toward the limit block 205 to insert it into the notch of the limit block 205, and the latch 201 is rotated downward to align the top folding rod with the gap of the C-shaped limit ring 203. The openings are staggered to prevent the latch 201 from moving backwards along the notch of the C-shaped limit ring 203 and losing its limit function; the storage box 1 equipped with the unloading plate 3 is fixed to the bottom crossbeam of the car with bolts and nuts. When unloading is required, the latch 201 is rotated to open the tailgate 2, the rear part of the unloading plate 3 is held and pulled outward, and the roller 305 rolls along the groove track 101 to bring the unloading plate 3 out, and the front end of the vertical rod 302 protrudes from the front end of the unloading plate 3, and the groove track 101 ends at a short distance from the tailgate 2, preventing the roller 305 from being completely pulled out of the storage box 1 and falling to the ground. After the unloading plate 3 is completely pulled out of the storage box 1, the end with the hook 306 is lifted upward, and the gas spring 303 is extended to push the top of the unloading plate 3 upward, and the hook 306 is lifted upward. The hook 306 is hung on the lifting ear on the outer side of the rear frame of the car. The installed unloading plate 3 is in an inclined state, providing a ramp for the trolley for loading and unloading goods to get on and off the car. The unloading plate 3 can rotate around the support leg 301 to form different slopes to adapt to cars of different heights. After use, the hook 306 is removed from the lifting ear, and the unloading plate 3 is pressed to contract the gas spring 303. After the gas spring 303 is fully retracted, the unloading plate 3 is stuffed into the storage box 1, and the tailgate 2 is covered and locked to prevent the unloading plate 3 from sliding out of the storage box 1; the telescopic unloading plate 3 is easy to store, and can also reasonably utilize the space under the car, provide convenience for workers to load and unload goods, reduce labor intensity, and has a high safety factor, eliminating safety hazards during manual loading and unloading of goods.
