Description

Technical Field

[0001] This utility model relates to the field of scooter technology, and in particular to a children's scooter with an adjustable steering wheel height. Background Technology

[0002] In the current children's toy car market, the twist car, as a popular recreational tool among children, must prioritize safety in its design, in addition to its entertainment and fun aspects. One important feature in the design of a twist car is the adjustable steering wheel height, as it directly affects the child's comfort and ease of operation while driving.

[0003] Traditionally, the steering wheel height adjustment mechanism of children's scooters generally uses a threaded locking method to fix or adjust the steering wheel height. This method requires the user to apply considerable force to rotate the nut, ensuring a tight fit between the adjusting rod and the nut to stabilize the steering wheel height. For children, this force requirement may be beyond their capabilities, requiring adult assistance. This undoubtedly reduces the ease of operation and independence. Furthermore, each time the steering wheel height is adjusted, force must be applied to tighten or loosen the adjusting rod, making it inconvenient to adjust the steering wheel height. If the threaded locking is not tight enough, the steering wheel may loosen during use, potentially causing a safety accident and posing a potential injury to the child. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A children's scooter with an adjustable steering wheel height includes a seat, two wheels are fixed to one side of the bottom of the seat, a foot pedal is fixed to the side of the seat away from the wheels, a hollow tube is inserted into the top of the seat away from the wheels, a rotating shaft is rotatably mounted inside the hollow tube, a wheel is mounted on the end of the rotating shaft away from the seat via a bracket, an adjustment rod is mounted on the end of the rotating shaft away from the wheel, and a steering wheel is fixed to the end of the adjustment rod away from the hollow tube.

[0008] The top of the rotating shaft is provided with an adjustment groove for engaging the adjustment rod. Flat end plates are fixed on both sides inside the adjustment groove. Multiple positioning protrusions are welded to the opposite surfaces of the flat end plates on both sides, and a slot is formed between two adjacent positioning protrusions on the same side. Two square plates are movably installed at the bottom inside the adjustment rod. Three locking strips are installed on the opposite back surfaces of the two square plates. Multiple through slots for the locking strips to pass through are provided on both sides of the adjustment rod.

[0009] As an improved technical solution, guide strips are fixed on both the front and rear sides of the inner wall of the adjustment groove, and limiting cavities for sliding the guide strips are opened on both the front and back sides of the adjustment rod.

[0010] As an improved technical solution, each of the four corners of the square plate is provided with a sliding hole, and a guide rod is slidably connected to the square plate through the sliding hole. The two ends of the guide rod are respectively fixed to the opposite end faces of the two planar end plates, and a spring is sleeved on the guide rod and located between the two square plates.

[0011] As an improved technical solution, a magnetic plate is fixed in the middle of the opposite sides of the two square plates, and the opposite sides of the two magnetic plates are magnetically attracted to each other. A sealing cover is fixed at the top of the adjusting rod, and a magnetic shielding plate is movably installed on the sealing cover through a cavity opened at its top.

[0012] As an improved technical solution, the magnetic shielding plate is fixed with fixed protrusions on both sides, and the bottom of the sealing cover is fixed with sliding rods on both sides of the magnetic shielding plate. The fixed protrusions are provided with sliding holes for the sliding rods to pass through, and the bottom end of the sliding rod is fixed with a stop block at the bottom of the fixed protrusions.

[0013] As an improved technical solution, a spring is fitted on the slide rod between the fixed protrusion and the sealing cover, and a hand buckle hole is opened at the end of the magnetic shield away from the magnetic plate.

[0014] As an improved technical solution, a storage groove communicating with the movable slot is provided in the middle of the top of the steering wheel, and the top of the magnetic shield is located inside the storage groove, and an end cap is snapped onto the storage groove.

[0015] After adopting the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, the engagement between the locking strip and the slot secures the adjusting rod to the rotating shaft. Pulling the magnetic shield upwards moves the locking strip out of the slot, and pushing the magnetic shield downwards inserts the locking strip into the slot. In other words, the steering wheel height can be adjusted by vertically moving the magnetic shield, which is very convenient and quick. Furthermore, the adjusting rod is secured by three locking strips on the same side inside the slot. The engagement of multiple locking strips on one side effectively improves the firmness and stability of the adjusting rod, thus enhancing the safety of the scooter.

[0017] 2. In this utility model, the magnetic shielding plate is vertically raised and lowered by the vertical positioning and guidance of the sliding rods on both sides and the fixed protrusion. The magnetic shielding plate is tilted during the upgrading process to ensure the magnetic shielding plate maintains its magnetic shielding state against the two magnetic plates. Furthermore, when the magnetic shielding plate is raised, the fixed protrusion will compress the second spring. When it is necessary to move the magnetic shielding plate downward to reset, the magnetic shielding plate is released and the elastic reset action of the second spring will automatically drive the magnetic shielding plate to reset, making the magnetic shielding plate more convenient to use.

[0029] like Figures 1 to 4 As shown in the figure, this embodiment provides a child's twist car with an adjustable steering wheel height. This child's twist car with an adjustable steering wheel height includes a seat board 1. Two wheels 13 are fixed to one side of the bottom of the seat board 1. A foot pedal 11 is fixed to the side of the seat board 1 away from the wheels 13. A hollow tube 14 is inserted and installed on the top of the seat board 1 away from the wheels 13. A rotating shaft 2 is rotatably installed inside the hollow tube 14. A wheel 12 is installed on the end of the rotating shaft 2 away from the seat board 1 through a bracket. An adjusting rod 3 is installed on the end of the rotating shaft 2 away from the wheel 12. A steering wheel 15 is fixed to the end of the adjusting rod 3 away from the hollow tube 14.

[0030] The top of the rotating shaft 2 is provided with an adjustment groove 21 for engaging the adjustment rod 3. Flat end plates 23 are fixed on both sides inside the adjustment groove 21. Multiple positioning protrusions 22 are welded to the opposite surfaces of the flat end plates 23 on both sides, and a slot is formed between two adjacent positioning protrusions 22 on the same side. Two square plates 32 are movably installed at the bottom inside the adjustment rod 3. Three locking strips 371 are installed on the opposite sides of the two square plates 32, and the locking strips 371 engage with the slots. Multiple through slots 3 for the locking strips 37 to pass through are provided on both sides of the adjustment rod 3.

[0031] The engagement between the locking strip 37 and the slot secures the adjusting rod 3 to the rotating shaft 2. Pulling the magnetic shielding plate 33 upwards moves the locking strip 37 out of the slot, while pushing the magnetic shielding plate 33 downwards inserts the locking strip 37 into the slot. In other words, the height of the steering wheel 15 can be adjusted by vertically moving the magnetic shielding plate 33, which is very convenient and quick. Furthermore, the three locking strips 37 on the same side are engaged inside the slot to secure the adjusting rod 3. The engagement of multiple locking strips 37 on one side effectively improves the firmness and stability of the fixing of the adjusting rod 3, thereby enhancing the safety of using the scooter.

[0032] like Figures 2 to 3 As shown in the figure, in this embodiment, guide strips are fixed on the front and rear sides of the inner wall of the adjusting groove 21, and limiting cavities for sliding of the guide strips are opened on the front and back sides of the adjusting rod 3.

[0033] like Figures 2 to 3 As shown in the figure, in this embodiment, sliding holes are provided at the four corners of the square plate 32. The square plate 32 is slidably connected to the guide rod 36 through the sliding holes, and the two ends of the guide rod 36 are respectively fixed to the opposite end faces of the two planar end plates 23. A spring 35 is sleeved on the guide rod 36 and located between the two square plates 32.

[0034] like Figures 2 to 3 As shown in the figure, in this embodiment, magnetic plates 34 are fixed in the middle of the opposite sides of the two square plates 32, and the opposite sides of the two magnetic plates 34 are magnetically attracted to each other. A sealing cover 38 is fixed at the top of the adjusting rod 3. A magnetic shielding plate 33 is movably installed on the sealing cover 38 through a cavity opened at its top. The magnetic shielding plate 33 is located between the two magnetic plates 34 and separates the two magnetic plates 34. A movable groove for the magnetic shielding plate 33 to pass through is opened in the middle of the steering wheel 15.

[0035] like Figures 2 to 4As shown in the figure, in this embodiment, both sides of the magnetic shielding plate 33 are fixed with fixing protrusions 311, and the bottom of the sealing cover 38 is fixed with sliding rods 310 on both sides of the magnetic shielding plate 33. The fixing protrusions 311 are provided with sliding holes for the sliding rods 310 to pass through. The bottom end of the sliding rods 310 is fixed with a stop block 312 at the bottom of the fixing protrusions 311. Under the vertical positioning and guidance of the sliding rods 310 and the fixing protrusions 311 on both sides, the magnetic shielding plate 33 is in a vertical lifting position, so that the magnetic shielding plate 33 tilts during the upgrade to ensure the magnetic shielding state of the magnetic shielding plate 33 to the two magnetic plates 34.

[0036] like Figure 4 As shown, in this embodiment, a second spring 39 is fitted on the slide rod 310 between the fixed protrusion 311 and the sealing cover 38. When the magnetic shielding plate 33 is lifted, the fixed protrusion 311 will compress the second spring 39. When it is necessary to move the magnetic shielding plate 33 downward to reset, the magnetic shielding plate 33 can be automatically driven to reset under the elastic reset action of the second spring 39 after the magnetic shielding plate 33 is released. The magnetic shielding plate 33 is more convenient to use. A hand buckle hole 313 is provided at the end of the magnetic shielding plate 33 away from the magnetic plate 34. The setting of the hand buckle hole 313 makes it easier to drive the magnetic shielding plate 33 to move.

[0037] like Figure 1 As shown, in this embodiment, a storage groove 16 communicating with the movable groove is provided in the middle of the top of the steering wheel 15, and the top of the magnetic shielding plate 33 is located inside the storage groove 16. An end cap is snapped onto the storage groove 16.

[0038] When using the steering wheel 15, if the height needs to be adjusted, open the end cap that is clipped onto the storage groove 16 to expose the magnetic shielding plate 33 located inside the storage groove 16.

[0039] With your fingers gripping the inside of 213, lift the magnetic shielding plate 33 upwards and move it away from the middle of the two magnetic plates 34. With the two magnetic plates 34 magnetically attracted to each other, move the two square plates 32 toward the center, shortening the gap between the two square plates 32 and compressing the spring 35. After the gap between the two square plates 32 is shortened, the locking strip 37 will move toward the inside of the adjusting rod 3, disengaging from the slot formed between the two adjacent positioning protrusions 22. At this time, the steering wheel 15 can be vertically adjusted to drive the adjusting rod 3 to make vertical adjustments and adjust the height of the steering wheel 15.

[0040] After adjustment, place the magnetic shielding plate 33 between the two magnetic plates 34 to release the attraction between the two magnetic plates 34. Under the elastic reset action of the spring 35, push the two square plates 32 outward to reset, so that the locking strip 37 enters the nearest position slot and engages, thus completing the adjustment of the steering wheel 15 height.

[0041] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
