Description

Technical Field

[0002] A children's scooter is an auxiliary prop that allows users to exercise their athletic ability by sliding forward with their feet. As demand changes, some children's scooters have also added circuit modules to achieve corresponding functions, such as: music playing, providing lighting or beautiful decorative lights, etc. Correspondingly, control buttons will be set on the frame to control the corresponding circuit modules.

[0003] The existing control button mainly includes a circuit board arranged inside the frame, a switch element assembled on the circuit board, and an operating element inserted into a button hole correspondingly opened on the frame. The inner end of the operating element extends into the frame as a control end and correspondingly abuts against the switch element to control the on and off of the switch element, while the outer end is exposed from the button hole as an operating end for the user to press.

[0004] The inventor found during the specific implementation that due to the lack of effective waterproof structure design, water or other liquids from the outside can easily flow in through the gap between the operating element of the control button and the button hole and flow along the outer wall of the operating element to the circuit board, which can easily cause various circuit safety problems such as circuit short circuit. In response to this, the industry also adds a waterproof sealing rubber ring in the gap between the button hole and the operating element to block the gap to prevent liquid from flowing in. However, since the operating element is often pressed, the waterproof sealing rubber ring is easily aged due to repeated friction over a long period of time, and the waterproof effect will be greatly reduced or even completely ineffective.

[0034] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following exemplary embodiments and descriptions are only used to explain the present invention and are not intended to limit the present invention. In addition, the embodiments and features in the embodiments of the present invention may be combined with each other without conflict.

[0035] like Figure 1-Figure 9As shown, an optional embodiment of the utility model provides a control button for a children's scooter, comprising a circuit board 3 assembled inside a frame 1 of the scooter, a switch element 5 assembled on the circuit board 3, and a control element 7 correspondingly arranged in a button hole 10 opened on the frame 1, wherein the inner end of the control element 7 extends into the frame 1 as a control end 70 and correspondingly abuts against the switch element 5 to control the on and off of the switch element 5, and the outer end is exposed from the button hole 10 as an operating end 72 for a user to press, and the side surface of the inner end of the control element 7 is also correspondingly extended outward to form a stop ring edge 74 for receiving liquid from the outside flowing in through the gap between the hole wall of the button hole 10 and the side wall of the control element 7, and the control button also includes a guide structure 76 for guiding the liquid received by the stop ring edge 74 along a path correspondingly avoiding the circuit board 3 to a position below the installation position of the circuit board 3.

[0036] The embodiment of the utility model forms a stop ring edge 74 on the side of the inner end of the operating element 7 for receiving the liquid flowing in from the outside through the gap between the hole wall of the button hole 10 and the side wall of the operating element 7. The stop ring edge 74 can also abut against the periphery of the inner end hole of the button hole 10 to prevent the operating element 7 from falling out of the button hole 10. In addition, a guide structure 76 is correspondingly provided for guiding the liquid received by the stop ring edge 74 along a path correspondingly avoiding the circuit board 3 to a position below the installation position of the circuit board 3, so that the stop ring edge 74 can be used to prevent the liquid from falling directly on the circuit board 3, and then the guide structure 76 is used to guide the liquid received by the stop ring edge 74 to a position below the installation position of the circuit board 3, and then it flows out from the corresponding joints or drainage holes at the bottom of the vehicle frame 1. The liquid will not contact the circuit board 3, and will not cause circuit safety failures such as circuit short circuits, and the safety is high. Compared with the traditional waterproof structure, the embodiment of the utility model uses dredging instead of blocking, and the structural reliability is high.

[0037] In an optional embodiment of the present invention, Figure 1-Figure 3As shown, the guide structure 76 includes a converging annular wall 760 extending from the edge of the stop ring 74 toward the operating end 72, a drain port 762 provided at a predetermined position of the converging annular wall 760, and a drain groove 764 extending from the drain port 762 to a direction away from the operating end 72. The converging annular wall 760, the stop ring 74, and the outer wall of the operating element 7 cooperate to form a converging groove 765, and the bottom outlet of the drain groove 764 is lower than the installation position of the circuit board 3. This embodiment provides a specific structure of the guide structure 76, which is formed by the converging annular wall 760, the stop ring 74, and the outer wall of the operating element 7 to form a converging groove 765. The liquid received by the stop ring 74 flows along the converging groove 765 to the drain port 762, and then is guided by the drain groove 764 to be discharged to a position lower than the installation position of the circuit board 3, which can effectively prevent the liquid from contacting the circuit board 3.

[0038] In an optional embodiment of the present invention, Figure 2 and Figure 3 As shown, the diversion structure 76 further includes a water diversion nozzle 766 extending axially from the periphery of the inner end opening of the button hole 10, and the water diversion nozzle 766 extends into the inner side of the converging annular wall 760. In this embodiment, by further forming a water diversion nozzle 766 at the inner end opening of the button hole 10, the liquid flowing in along the hole wall of the button hole 10 can be well diverted to the stop ring edge 74.

[0039] In another optional embodiment of the present invention, Figure 4-Figure 6 As shown, the guide structure 76 includes a guide annular wall 768 extending from the outer edge of the stop ring 74 in a direction away from the operating end 72, and the guide annular wall 768 and the stop ring 74 together form an open storage space on the side away from the operating end 72, and the circuit board 3 is completely assembled in the storage space. This embodiment provides another guide structure 76, in which the guide annular wall 768 and the stop ring 74 together form a storage space, and the circuit board 3 is completely assembled in the storage space. The liquid received on the stop ring 74 flows along the outer wall of the guide annular wall 768 without contacting the circuit board 3 in the storage space.

[0040] In another optional embodiment of the present invention, combined with Figure 2 , Figure 3 and Figure 6As shown, the operating element 7 has an accommodating cavity 78 with an opening on the inner end surface, and a pressing column 79 is protruding toward the opening from the middle of the cavity wall of the accommodating cavity 78, and the end of the pressing column 79 constitutes the control end 70. In this embodiment, the accommodating cavity 78 is formed inside the operating element 7, and a pressing column 79 is further formed in the accommodating cavity 78 to constitute the control end 70. On the one hand, the material consumption when producing the operating element 7 is reduced, and the control end 70 formed by the pressing column 79 can effectively abut the switch element 5.

[0041] In another optional embodiment of the present invention, Figure 8-Figure 9 As shown, the operating element 7 has an accommodating cavity 78 with an opening on the inner end face formed therein, a pressure column 79 is provided in the middle of the cavity wall of the accommodating cavity 78 opposite to the opening and protruding toward the opening, and the end of the pressure column 79 constitutes the control end 70, and the guide structure 76 includes a mounting platform 77 fixed to the frame 1 and correspondingly inserted into the accommodating cavity 78, and a mounting cavity 770 for accommodating the circuit board 3 is also formed inside the mounting platform 77, and a through hole 772 connected with the mounting cavity 770 for the control end 70 to pass through is formed on one end face of the mounting platform 77 corresponding to the insertion into the accommodating cavity 78. In this embodiment, a receiving cavity 78 is formed on the inner end surface of the operating element 7, and a mounting platform 77 fixedly arranged on the frame 1 is used as a guide structure 76, and the circuit board 3 is assembled in the mounting cavity 770 inside the mounting platform 77. One end of the mounting platform 77 is also inserted into the receiving cavity 78, and the control end 70 of the operating element 7 is inserted from the mounting platform into the receiving cavity 78. The through hole 772 opened on the end surface of one end of the mounting platform is inserted into the mounting cavity 770 to abut against the switch element 5 on the circuit board 3. Therefore, when the liquid on the retaining ring edge 74 flows further, it will only flow to the side wall of the mounting platform 77, and then flow downward along the side wall of the mounting platform 77, and will not enter the mounting cavity 770 inside the mounting platform 77 to contact the circuit board 3, which can well play the role of guiding and avoiding the circuit board 3.

[0042] In another optional embodiment of the present invention, combined with Fig. 9As shown, the control button also includes a reset elastic member 9 which is correspondingly sleeved on the pressure column 79 and has one end abutting against the cavity wall of the accommodating cavity 78 facing the opening and the other end fixed relatively to the switch element 5 to push the operating element 7 to move away from the switch element 5. In a specific implementation, the reset elastic member 9 can be a common elastic element such as a spring and an elastic rubber sleeve. In this embodiment, by adding a reset elastic member 9, the operating element 7 can be compressed to accumulate elastic potential energy when the operating element 7 is pressed, and can quickly push the operating element 7 to reset when the operator releases the operating element 7 to facilitate the next operation. Of course, when used in conjunction with some switch elements 5 that have an elastic reset function, the elastic reset kinetic energy of the switch element 5 can also be used to push the operating element 7 to reset, without the need to provide the reset elastic member 9 (such as Figure 1-Figure 6 shown).

[0043] On the other hand, Fig.11 As shown, an embodiment of the utility model further provides a children's slide, comprising a frame 1 and a control button assembled on the frame 1, wherein the control button is the control button as described in any of the aforementioned embodiments.

[0044] This embodiment uses the control button as described in any of the above embodiments, which can effectively prevent liquid from contacting the circuit board 3 and will not cause circuit safety failures such as circuit short circuits. It has high safety and high structural reliability.

A vertical axis 20 protrudes upward from the top of the front wheel bracket 2, and a rotation limiting groove 200 extending axially and having a predetermined circumferential length is provided on the outer wall of the vertical axis 20. A through hole 12 is provided at the front end of the frame 1 for the vertical axis 20 to pass through, and a limiting protrusion 120 is provided on the inner wall of the through hole 12 protruding toward the hole and correspondingly inserted into the rotation limiting groove 200 and used to abut against the groove side wall of the rotation limiting groove 200 to limit the rotation angle travel of the front wheel bracket 2 relative to the frame 1. The handle 6 includes a grip rod 60 for a user to hold and a grip rod 60 protruding downward from the bottom of the middle section of the grip rod 60. The sleeve 62 has a plurality of positioning protrusions 620 symmetrically arranged on the inner side wall of the sleeve 62 and a plurality of hook holes 622 symmetrically arranged on the top wall of the sleeve 62. The top of the vertical shaft 20 is symmetrically provided with elastic hooks 22. A limiting abutment platform 14 is also provided on the frame 1. The sleeve 62 is sleeved on the top end of the vertical shaft 20. The bottom end surface of the sleeve 62 abuts against the limiting abutment platform 14 and the elastic hook 22 at the top end of the vertical shaft 20 passes through the hook hole 622 and is hooked on the top periphery of the hook hole 622 to fix the sleeve 62 and the vertical shaft 20 in the axial direction. The positioning protrusion 620 is correspondingly inserted into the rotation limiting groove 200 on the outer side wall of the vertical shaft 20 and abuts against the corresponding groove side wall of the rotation limiting groove 200 to fix the sleeve 62 and the vertical shaft 20 in the circumferential direction. In this embodiment, the front wheel bracket 2 and the handlebar 6 can be quickly assembled onto the frame 1, and the front wheel bracket and the handlebar are relatively fixed, and the front wheel bracket can be driven by the handlebar 6 to flexibly rotate relative to the frame 1 within a corresponding angle range to implement steering control of the scooter.
