[0032] In this embodiment, the retracting and lifting mechanism includes a groove body 15, a slider 18, a first compression spring 16, a torsion spring, a bearing and a shaft rod 17. The groove bodies 15 are all embedded and installed on the inner side surface of the positioning frame 2. The sliders 18 are all slidably arranged in the groove bodies 15. Mounting grooves are provided on the opposite surfaces of the sliders 18. Bearings are installed at the deepest parts of the mounting grooves. Torsion springs are installed in the openings of the mounting grooves. One end of the shaft rod 17 is installed in the inner ring of the bearing, and the other end passes through the inner ring of the torsion spring and is fixedly connected to the positioning part 4. One end of the torsion spring is installed on the inner wall surface of the mounting groove, and the other end is fixedly connected to the shaft rod 17. One end of the first compression spring 16 is installed on the slider 18, and the other end is installed on the inner wall surface of the groove body 15;

[0033] Among them, the groove body is made of metal material, which increases the firmness, enables the slider to perform long-term friction along the groove body, and a rubber layer for friction with the slider is installed on the inner wall surface of the groove body, and the moving speed of the slider is reduced through the rubber layer.

[0034] In this embodiment, the locking mechanism includes a positioning plate 13, a collision-receiving block 6, a positioning column 11, a second compression spring 12 and a limiting block 5. A plurality of limiting grooves are provided on the surface of one vertical end of the protection frame 1. Positioning holes communicating with the outside are provided on the inner wall surfaces of the limiting grooves. The limiting blocks 5 are all arranged at the openings of the limiting grooves. One end of the limiting block 5 is fixedly connected to the positioning column 11. The other end of the positioning column 11 passes through the positioning hole and extends to the outside and is fixedly connected to the positioning plate 13. A slot 20 is provided at one end of the blocking plate 3. One end of the positioning plate 13 is bent to form an insertion part, and the insertion part is inserted into the slot 20. The other end of the positioning plate 13 is fixedly connected to the collision-receiving block 6. One end of the collision-receiving block 6 protrudes from the surface of the protection frame. The second compression springs 12 are all sleeved on the positioning columns 11. One end of the second compression spring 12 is installed on the limiting block 5, and the other end is installed on the inner wall surface of the limiting groove;

[0035] Among them, the length of the collision-receiving block can match the width of the protection frame to increase the contact area, so as to better trigger the lifting work of the blocking plate.

[0036] In this embodiment, the limiting mechanism includes a fixed seat 8, a positioning block 9 and a third compression spring. The fixed seats 8 are all installed on the positioning frame 2. Positioning grooves are provided on the opposite surfaces of the fixed seats 8. One end of the positioning block 9 is inserted into the positioning groove and is all installed with a third compression spring. The other end of the third compression spring is installed on the inner wall surface of the positioning groove. The other end of the positioning block 9 is all arranged outside. A positioning strip 10 is installed on one side of the positioning frame 2 where the two limiting mechanisms are located. A first limiting part is inclined on one side surface of the positioning strip 10. A second limiting part 19 is inclined on the side of the positioning block 9 facing the positioning strip 10. The first limiting part and the second limiting part 19 are horizontally arranged. A diversion part 14 is inclined on the side of the positioning block 9 facing the positioning part 4.

[0037] In this embodiment, grooves 21 are provided on both sides of the blocking plate 3, widening plates 22 are provided inside the grooves 21, one end of the reinforcing plate is fixedly connected to the blocking plate 3 through a hinge, and the opposite side of the reinforcing plate is set against the inner side of the protective frame 1;

[0038] Among them, the hinged part is a torsion spring hinge. After the blocking plate is lifted, the widened plate can be opened outwards through the twisting of the torsion spring hinge. The widened plate can better intercept the rider leaning forward, further increasing the safety of riding.

[0039] In this embodiment, a retreat space is formed between one end of the blocking plate 3 and the protective frame 1 and between one end of the positioning portion 4 and the positioning frame 2, so that the blocking plate can retreat smoothly.

[0040] In this embodiment, a fixing plate 7 is installed at one end of the positioning frame 2 away from the locking mechanism, and the other end of the fixing plate 7 extends to the inner side of the electric bicycle frame and is fixedly connected to the frame by bolts.

[0041] In this embodiment, the protection frame 1 and the positioning frame 2 are integrally formed, and the blocking plate 3 and the positioning portion 4 are also integrally formed. The integral forming method can be performed by injection molding, thereby reducing production costs.

[0042] In this embodiment, the protective frame 1 and the blocking plate 3 are both made of PC plastic material. PC plastic has high mechanical strength and excellent impact resistance. This property makes PC plastic have significant advantages in application scenarios that need to withstand high impact forces. PC plastic also has high elasticity, which means that it can maintain good shape stability when subjected to external forces and is not prone to permanent deformation.

[0043] One end of the protection frame and the blocking plate extends to the front of the basket, so when it is hit from the front, it will contact the protection frame and the blocking plate, and the elasticity of the protection frame and the blocking plate can play a role of interception and protection, thus avoiding damage caused by direct contact with the frame or the basket;

[0044] Among them, once the impact force is large and exceeds the rebound of the second compression spring, the impacted block will retreat, and the movement of the impacted block drives the positioning plate to move stably along the positioning hole. As the positioning plate moves, the plug on the positioning plate will be pulled out of the slot;

[0045] After losing the block, since a rubber layer is installed on the inner wall surface of the slot body, the friction with the slider is increased through the rubber layer, so that the rebound of the first compression spring will reduce the lateral movement speed of the slider. The torsion speed of the torsion spring is faster than the backward speed, and the upward lift of the shaft rod and the blocking plate can be driven through torsion. During the lifting process, the backward movement of the slider can drive the backward movement of the shaft rod and the blocking plate, and the backward movement avoids the blocking plate being stuck due to contact with the impacted object.

[0046] As the blocking plate is lifted, the blocking plate will squeeze the diversion part, so that the positioning block is pressed into the positioning groove until the outer side surface of the blocking plate abuts against the first limiting part on the positioning strip. After the blocking plate abuts against the first limiting part, the positioning block can be pushed outwards through the rebound of the third compression spring until the inner side surface of the blocking plate abuts against the second limiting part on the positioning block. The blocking plate can be clamped between the first limiting part and the second limiting part, thereby positioning the blocking plate.

[0047] The lifted blocking plate provides protection for the rider, avoiding the situation of directly leaning forward or being thrown out and causing a frontal collision with the impacted object. The elastic property of the blocking plate can play a buffering and intercepting role, increasing safety.

[0048] Among them, after the impacted block is squeezed backward, the blocking plate can automatically lift, so that the basket can be opened smoothly. On the contrary, after the blocking plate is covered, it can block the blue cover of the basket, avoiding the situation of lifting during the riding process. Moreover, the protective frame and the blocking plate can block external rainwater, reducing the probability of internal items being wet.

[0049] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any change or replacement that can be thought of without creative work should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
