Description

Technical Field

[0001] This application relates to the field of electric scooter technology, and in particular to a children's electric scooter. Background Technology

[0002] Existing electric scooters, especially those with foldable front ends, can generally only be folded between the front end and the body. However, due to the long stem of the front end, the angle at which the front end can be bent is limited. The stem of traditional scooters is also quite long, and the volume of the stem after folding is relatively large. In addition, traditional electric scooters mostly use joint folding, segment folding, or hinge folding, which usually requires multiple steps (such as loosening buckles, adjusting knobs, aligning interfaces, etc.), making the folding structure and actual operation relatively complicated.

[0003] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is the closest prior art to this application. Summary of the Invention

[0004] Based on this, this application provides a children's electric scooter to solve one of the aforementioned technical problems.

[0005] The technical solution adopted by this application to solve its technical problem is: a children's electric scooter, comprising: a head section and a body section, wherein the head section rotates on the body section, and a first rotating mechanism is provided at the hinge joint between the head section and the body section; the head section includes a vertical tube, and a second rotating mechanism for bending the vertical tube is provided on the vertical tube; the first rotating mechanism includes a limiting plate provided on the body section and a locking wrench rotating on the head section, wherein the limiting plate has several limiting grooves, and the locking wrench is operated to enter or disengage from the limiting plate. The vehicle head is locked or unlocked by means of a limiting groove; the riser includes an upper section and a lower section that are hinged to each other, and the second rotating mechanism is disposed at the connection between the upper section and the lower section, including a mounting box, in which a driven gear rotates; a half-tooth structure is provided at the bottom of the lower section, which meshes with the driven gear; a pull pin is slidably disposed in the mounting box, and the pull pin has a smooth rod section and a toothed section that can mesh with the driven gear; the end of the pull pin is fixed to a tension spring, and the upper section is unlocked by pulling the pull pin.

[0006] In some embodiments, there are two limiting plates, which are arranged parallel to each other on the top of the vehicle body, and the front of the vehicle is hinged between the two limiting plates.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0023] In the embodiments of this application, please refer to Figure 1-8As shown, this children's electric scooter mainly includes: a head section 1 and a body section 2. The head section 1 rotates on the body section 2. A first rotating mechanism is provided at the hinge joint between the head section 1 and the body section 2. The head section 1 includes a vertical tube 3, and a second rotating mechanism for bending the vertical tube 3 is provided on the vertical tube 3. The first rotating mechanism includes a limiting plate 4 provided on the body section 2 and a locking wrench 5 rotating on the head section 1. The limiting plate 4 has several limiting grooves 6. The head section 1 is locked or unlocked by operating the locking wrench 5 to enter or disengage from the limiting grooves 6. The vertical tube 3 includes an upper section 301 and a lower section 302 that are hinged to each other. The second rotating mechanism is provided at the connection between the upper section 301 and the lower section 302 and includes a mounting box 7. A driven gear 8 rotates within the mounting box 7. A half-tooth structure 19 is provided at the bottom of the lower section 302, which meshes with the driven gear 8. A pull pin 9 is slidably disposed within the mounting box 7. The pull pin 9 has a smooth rod section 901 and a toothed section 902 that can mesh with the driven gear 8. The end of the pull pin 9 is fixed to a tension spring 10. Pulling the pull pin 9 unlocks the upper section 301. Through the meshing transmission between the half-tooth structure 19 and the driven gear 8, compared with a direct rigid connection, the design of the half-tooth structure 19 disperses stress, avoids excessive load on a single component, thereby reducing wear and extending the service life of the equipment. In addition, the presence of the half-tooth structure 19 allows for more precise control of the transmission ratio and motion trajectory, improving the accuracy and stability of the transmission.

[0024] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0025] like Figure 3 As shown, there are two limiting plates 4, which are arranged in parallel on the top of the vehicle body 2. The vehicle head 1 is hinged between the two limiting plates 4. The two limiting plates 4 serve to limit and install the vehicle head 1. The two sides of the vehicle head 1 are coaxially hinged to the two limiting plates 4.

[0026] Furthermore, a locking post 501 is formed at one end of the locking wrench 5. The locking post 501 is used to lock the vehicle head 1 by being inserted into the limiting groove 6. A movable groove 11 is provided on the vehicle head 1 for the locking post 501 to move. A return spring 12 is provided between the locking wrench 5 and the movable groove 11. When the locking wrench 5 is rotated on the vehicle head 1, the locking post 501 at its end can be lifted and disengaged from the limiting groove 6 to unlock the vehicle head 1. After the locking wrench 5 is released, the locking post 501 is subjected to a downward reset force under the action of the return spring 12. After the position of the vehicle head 1 is adjusted by rotation, the locking post 501 can automatically return to its original position in the limiting groove 6 to complete the locking again.

[0027] like Figure 5-7 As shown, the mounting box 7 has a positioning groove 13 and a movable opening 14. A movable column 20 is formed on the upper section 301. The movable column 20 moves within the positioning groove 13. The movable opening 14 provides space for the upper section 301 to bend. The width of the movable opening 14 is the same as the width of the upper end of the riser 3. To prevent children from accidentally inserting their fingers into the movable opening 14, a protective cover that can be opened and closed is preferably provided at the movable opening 14. When it is necessary to rotate and fold the upper section 301, the protective cover can be opened to open the movable opening 14.

[0028] Furthermore, a receiving chamber 15 is formed on one side of the mounting box 7, and the pull pin 9 is movable inside the receiving chamber 15. Lugs 16 are formed on both sides of the pull pin 9. A through hole 17 is opened at the end of the receiving chamber 15. The pull pin 9 and the lugs 16 slide in the through hole 17. A pull ring 18 is provided at the end of the pull pin 9. The diameter of the receiving chamber 15 is the same as the diameter of the toothed segment 902. When the pull pin 9 is pulled out by pulling the pull ring 18, the toothed segment 902 will be pulled out of the mounting box 7 and placed into the receiving chamber 15. At the same time, the lugs 16 on the pull pin 9 always fit against the inner wall of the through hole 17 to limit the pull pin 9, so that the pull pin 9 can only be pulled out laterally and cannot be rotated.

[0029] Furthermore, one end of the tension spring 10 is fixed to the inner wall of the mounting box 7, and the other end is fixed to the tension spring 10. The sliding direction of the tension spring 10 is parallel to the axial direction of the driven gear 8. Pulling the pull pin 9 causes the toothed section 902 to be placed in the receiving chamber 15, which disengages the toothed section 902 from the driven gear 8. After pulling out the toothed section 902 and placing it into the receiving chamber 15, the upper section 301 of the riser tube 3 can be rotated for folding. After rotating the upper section 301 to a suitable position, the pull ring 18 is released. Under the action of the tension spring 10, the pull pin 9 automatically resets. Continue to fine-tune the upper section 301 at a small angle until the toothed section 902 engages with the driven gear and the pull pin 9 is fully reset, thus relocking the driven gear and completing the locking of the upper section 301 after bending and folding.

[0030] like Figure 8 As shown, when folding the electric scooter, first bend the pull pin 9 on the second rotating mechanism to unlock and bend the upper section 301. Then operate the locking wrench 5 on the first rotating mechanism to unlock and bend the head section 1. After that, relock the upper section 301 and the head section 1 to complete the folding of the electric scooter. This optimizes the compactness of the folded structure and further reduces the space occupied after folding. At the same time, the folding and bending operations are relatively simple, and the stability after unlocking and locking is good. It should be noted that on the uprights 3 of different lengths, it is only necessary to reasonably set the height of the second rotating mechanism on the upright (i.e., the length of the upper section 301 and the lower section) to achieve the appropriate technical effect after folding.

Those skilled in the art can fully understand how to implement the technical solutions disclosed herein based on the above description.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of this application. The foregoing embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
