Detailed implementation method:

[0035] The present invention will be further described below with reference to specific embodiments. See also: Figure 1 —5:

[0036] An installation structure for the rear cargo bed of a scooter includes a vehicle body 1 and a rear cargo bed 2. The rear cargo bed 2 has an insert plate 3 at its front end, and the vehicle body 1 has an installation groove 4 for inserting the insert plate 3 at its rear end. A sliding plate 5 and a slider 6 are slidably mounted on the insert plate 3. The sliding plate 5 slides longitudinally, and the slider 6 slides laterally. A fixing pin 7 is vertically mounted inside the installation groove 4. The slider 6 has a slot 8 for the fixing pin 7 to engage. An elastic element 9 is mounted on the slider 6. When the sliding plate 5 is pushed forward, the sliding plate 5 pushes the slider 6 away from the fixing pin 7, causing the elastic element 9 to undergo elastic deformation. The slot 8 then moves away from the fixing pin 7, and the insert plate 3 can slide longitudinally within the installation groove 4. When the sliding plate 5 is released, the slider 6 moves closer to the fixing pin 7 under the elastic force of the elastic element 9 until the fixing pin 7 engages with the slot 8, and the front end of the insert plate 3 is fixed within the installation groove 4.

[0037] The working principle of this invention is as follows: Figure 1-5 As shown, when installing the rear truck bed 2, first push the slide plate 5 forward so that the slider 6 moves away from the fixing pin 7, then insert the insert plate 3 into the mounting slot 4. Then, when releasing the slide plate 5, the slider 6 moves closer to the fixing pin 7 under the elastic force of the elastic element 9 until the fixing pin 7 is engaged in the slot 8, and the front end of the insert plate 3 is fixed in the mounting slot 4. When disassembling the rear truck bed 2, first push the slide plate 5 forward so that the slider 6 moves away from the fixing pin 7, then pull out the insert plate 3.

[0038] This invention utilizes a longitudinally sliding slide plate 5 that moves forward, pushing a laterally moving slider 6 away from the fixing pin 7 to unlock the fixing pin 7 from the slot 8. Then, the elastic element 9 causes the slider 6 to move back towards the fixing pin 7, locking the fixing pin 7 into the slot 8. The locking effect is good, and it is not easy for the slider to come loose. The invention has an ingenious structural design, and the connection between the insert plate 3 and the mounting slot 4 is firm, preventing the rear cargo box from falling off during the ride and effectively preventing damage from impacts.

[0039] Structure of slider 6 and fixing pin 7: Slider 6 includes a left slider 6a and a right slider 6b arranged opposite to each other.

The fixing pin 7 includes a left fixing pin 7a located on the left side of the left slider 6a and a right fixing pin 7b located on the right side of the right slider 6b. The elastic element 9 is a spring located between the left slider 6a and the right slider 6b. When the sliding plate 5 is pushed forward, the sliding plate 5 pushes the left slider 6a and the right slider 6b to move towards each other. The left slider 6a moves away from the left fixing pin 7a, and the right slider 6b moves away from the right fixing pin 7b, compressing the spring 9. Figure 4 As shown; when the slide plate 5 is released, the left slider 6a and the right slider 6b move in opposite directions under the elastic force of the spring 1, until the left fixing pin 7a engages with the slot 8 of the left slider 6a and the right fixing pin 7b engages with the slot 8 of the right slider 6b, as shown. Figure 3 As shown, the connection between the insert plate 3 and the mounting slot 4 is firm and reliable.
