Detailed Implementation

[0020] To make the objectives, technical solutions, and effects of this utility model clearer and more explicit, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] Please see Figures 1-24 The present invention provides an electric scooter, which includes: a body assembly 10, a wheel assembly 20, a steering wheel assembly 30, a display assembly 40, a switch control key 51, a circuit board 52, a first electrical connection assembly 60, and a second electrical connection assembly 70.

[0022] A body assembly 10 is used for user seating; a wheel assembly 20 is mounted on the bottom of the body assembly 10, and the wheel assembly 20 includes a front drive wheel set 21 and a driven wheel set 22. The front drive wheel set 21 is located near the front of the body assembly 10, and the driven wheel set 22 is located near the rear of the body assembly 10; a steering wheel assembly 30 connects the front drive wheel set 21 and the body assembly 10, and the steering wheel assembly 30 can control the rotation of the front drive wheel set 21, which drives the rotation of the driven wheel set. The connection between the body assembly 10 and the steering wheel assembly 30 can be through a bearing (not shown in the figures), in which case the body assembly 10 does not rotate with the steering wheel assembly 30; a display assembly. 40 is disposed on the outer surface of the front of the vehicle body component 10, for displaying predetermined patterns and / or text, or can also display animations that children like through program settings; the switch control key 51 is used to control the start and stop of the front drive wheel assembly 21. Of course, other control keys can also be set, such as control keys for RGB lighting effects if there are RGB lights inside the vehicle body, control keys for controlling the front drive wheel assembly 21, and control keys for the display screen of the display component 40, or control keys for the display screen display effects, etc., which are not limited here. Of course, the switch control key 51 can be a sensor switch control key or a manual switch button, which are not limited here. The switch control key 51 (such as Figure 17 As shown, both the display component 40 and the circuit board 52 are electrically connected to the circuit board 52, as are the other control switches mentioned above.

[0023] Specifically, the above structure is electrically connected to the front drive wheel assembly 21 via a first wire 601. When the steering wheel assembly 30 drives the front drive wheel assembly 21 to rotate, the steering wheel assembly 30 simultaneously drives the first electrical connection assembly 60 to rotate along with the front drive wheel assembly 21. It is electrically connected to the circuit board 52 via a second wire 701 and mounted on the body assembly 10. The first electrical connection assembly 60 always abuts against the second electrical connection assembly 70, so that the first electrical connection assembly 60 maintains an electrical connection with the second electrical connection assembly 70 while rotating with the front drive wheel assembly 21. The structure is also connected to the display assembly. 40 can display different effects, such as animation or text effects. Furthermore, through the contact electrical connection of the first electrical connection component 60 and the second electrical connection component 70, a direct wireless electrical connection is formed with the front drive wheel assembly 21. This allows the steering wheel assembly to drive the front drive wheel assembly 21 to rotate 360 ​​degrees, enhancing the fun for children playing with the electric twist car. The steering wheel assembly driving the front drive wheel assembly 21 to rotate 360 ​​degrees also sparks children's interest in the structure of the electric twist car. Parents' explanations further increase children's knowledge and enhance interaction between parents and children, improving the entertainment value of the electric twist car and providing a better user experience.

[0024] The aforementioned structure can further include a battery 90a, a Bluetooth control board 90b, and a foot switch 90c, such as... Figure 17 As shown, the battery and Bluetooth control board are disposed within the body assembly 10. The foot switch is installed on the body assembly 10 and electrically connected to the circuit board 52. When the user presses the foot switch, the circuit board 52 is activated. The battery supplies power to the Bluetooth control board and the circuit board 52 through the switch control button 51. The Bluetooth control board can control the horn, lights, and display component 40.

[0025] In this embodiment, a support member 80 is also included. The support member 80 is connected to the body assembly 10 and is rotatable relative to the steering wheel assembly 30, and is fitted onto the steering wheel assembly 30. The circuit board 52 and the second electrical connection assembly 70 are both disposed on the support member 80. The support member 80 is mainly for mounting the circuit board 52. The circuit board 52 is disposed on the support member 80 because most of the control buttons are located near the front of the scooter, and the front drive wheel assembly is also located below the front of the scooter. Therefore, mounting the circuit board 52 on the support member 80 facilitates the electrical connection of the second electrical connection assembly 70, the switch control button 51, and other control buttons and other electrical connectors to the circuit board 52. This shortens the wiring distance of the components that need to be electrically connected to the circuit board 52, which is convenient for overall layout and subsequent maintenance and repair.

[0026] Reference Figures 2-3In this embodiment, the first electrical connection assembly 60 and the second electrical connection assembly 70 are connected without wires. The first electrical connection assembly 60 includes a first rotating body 611 and two first electrical ring pieces 612. The first rotating body 611 is sleeved on the steering wheel assembly 30 and installed on the front drive wheel assembly 21, and is rotatably located inside the support member 80. The two first electrical ring pieces 612 are installed on the outer side of the first rotating body 611 and are disconnected. Two leads at one end of the first wire 601 are respectively connected to the two first electrical ring pieces 612. 12. The second electrical connection assembly 70 includes two first electrical contact assemblies 71. The support member 80 has two first mounting grooves 81 corresponding to the two first electrical ring pieces 612, and each of the two first mounting grooves 81 has a first through hole 811 on its sidewall facing the first rotating body 611. The two first electrical contact assemblies 71 are respectively installed in the two first mounting grooves 81, and the two first electrical contact assemblies 71 abut against the two first electrical ring pieces 612 through the two first through holes 811. Two leads at one end of the second wire 701 are respectively connected to the two first electrical contact assemblies 71. This structure... In other words, the first rotating body 611 and the two first electric ring plates 612 are mounted on the front drive wheel assembly 21, and the first electrical contact assembly 71 is mounted on the support member 80. The support member 80 and the body assembly 10 do not rotate with the steering wheel assembly. The steering wheel assembly 30 drives the front drive wheel assembly 21 to rotate, and the first rotating body 611 and the first electric ring plates 612 rotate with the front drive wheel assembly 21. The first wire 601 also rotates with the front drive wheel assembly 21. In this way, when the steering wheel assembly 21 drives the front drive wheel assembly 21, there will be no problem of wire entanglement. That is, the steering wheel assembly can drive the front drive wheel assembly 21 to achieve 360 ​​degrees. The first embodiment of the electrical connection method is that the first electrical ring 612 is disposed on the side wall of the first rotating body 611, which is equivalent to the first electrical contact assembly 71 being on the side of the first rotating body 611. The first electrical ring 612 rotates axially around the first electrical contact assembly 71. The two leads at one end of the second wire 701 and the two leads at one end of the first wire 601 each have one positive lead and one negative lead. This is the prior art and will not be described in detail here. The first rotating body 611 is cylindrical in shape and can be a cylindrical cylinder, so that the first electrical ring 612 can more smoothly contact and rotate with the first electrical contact assembly 71.

[0027] In a further embodiment of the first implementation scheme described above, the two first electroring plates 612 are respectively connected to a first pin 6121 and a second pin 6122 extending toward the interior of the front drive wheel assembly 21. The first pin 6121 is disposed close to the front drive wheel assembly 21. The first rotating body 611 is provided with a second through hole 6111 near one of the first electroring plates 612 away from the front drive wheel assembly 21. The second pin 6122 extends from the inner side of the rotating body toward the front drive wheel assembly 21 through the second through hole 6111. The two leads at one end of the first wire 601 are respectively connected to the first pin 6121. The first pin 6121 and the second pin 6122 are provided to facilitate the connection of the first wire 601. If the first wire 601 is directly connected to the front drive wheel assembly 21, the wire would be too long and inconvenient to route, making the connection of the first wire 601 difficult. The first pin 6121 and the second pin 6122 connected to the two first electric rings 612 are integrally formed, so that the electric ring and the pin are not easily broken. A through hole can be provided on the end of the first pin 6121 and the second pin 6122 away from the support, which facilitates the connection of the first wire 601. Figure 3 As shown.

[0028] In a further implementation of the first embodiment, the first electrical contact assembly 71 includes a first electrical contact block 711 and a first reset member 712. The first electrical contact block 711 abuts against the first electrical ring plate 612. One end of the first reset member 712 abuts against the groove wall of the first mounting groove 81, and the other end abuts against the first electrical contact block 711. A first mounting protrusion 7111 is provided at one end of the first electrical contact block 711 facing the first reset member 712, and the first reset member 712 is sleeved on the first mounting protrusion 7111. The first reset member 712 can be a spring, rubber, or an elastic sheet, but a spring is preferred because it is low in cost and has better elastic reset force. This makes the first electrical contact assembly 71 and the first electrical ring plate 612 more stable in contact and rotation. The first mounting protrusion 7111 facilitates the installation of the first reset member 712.

[0029] Reference Figures 4-6In this embodiment, a second implementation scheme is provided where the first electrical connection assembly 60 and the second electrical connection assembly 70 are electrically connected without wires. The front drive wheel assembly 21 has a first placement groove 211 on its top surface facing the support member 80. The second electrical connection assembly 70 includes a second rotating body 721 and two second electrical ring pieces 722. The second rotating body 721 is fixedly installed on the inner side of the support member 80 and sleeved on the steering wheel assembly 30, and is rotatably located in the first placement groove 211. The two second electrical ring pieces 722 are installed on the outer side of the second rotating body 721 and are disconnected. The two leads at one end of the second wire 701 are respectively connected to the two second electrical ring pieces. 722, the first electrical connection assembly 60 includes two second electrical contact assemblies 62. The sidewall of the first placement groove 211 is provided with two third through holes 2111 corresponding to the two second electrical ring pieces 722. The front drive wheel assembly 21 is provided with two second mounting grooves 212 away from the first placement groove 211 and corresponding to the two third through holes 2111. The two second electrical contact assemblies 62 are respectively installed in the two second mounting grooves 212, and the two second electrical contact assemblies 62 abut against the two second electrical ring pieces 722 through the two third through holes 2111. Two leads at one end of the first wire 601 are respectively connected to the two second electrical contact assemblies 62. This structure means that the second rotating body 721... The second electrical ring 722 is mounted on the support member 80, and the second electrical contact assembly 62 is mounted on the front drive wheel assembly 21. The support member 80 and the body assembly 10 do not rotate with the steering wheel assembly. The steering wheel assembly 30 drives the front drive wheel assembly 21 to rotate, and the second electrical contact assembly 62 rotates with the front drive wheel assembly 21. The first wire 601 also rotates with the front drive wheel assembly 21. In this way, when the steering wheel assembly drives the front drive wheel assembly 21, there will be no problem of wire entanglement. That is, the steering wheel assembly 21 can drive the front drive wheel assembly 21 to achieve a 360-degree rotation. In this second embodiment, the electrical connection method is that the second electrical ring 722 is set on the side wall of the second rotating body 721, which is equivalent to the second electrical contact assembly 62 being mounted on the second rotating body 721. On the side of body 721, the second electrical contact assembly 62 moves circumferentially around the second electrical ring plate 722. Compared with the first embodiment, in the first embodiment, the first electrical contact assembly 71 is fixed with the support member 80, while in the second embodiment, the second electrical contact assembly 62 rotates with the front drive wheel assembly 21. In the first embodiment, the first rotating body 611 and the first electrical ring plate 612 rotate with the front drive wheel assembly 21, while in the second embodiment, the second rotating body 721 and the second electrical ring plate 722 are fixed with the support member 80. The second rotating body 721 is cylindrical in shape and can be a cylindrical cylinder, so that the second electrical contact assembly 62 can more smoothly contact and rotate with the second electrical ring plate 722.

[0030] In a further embodiment of the second implementation described above, the two second electrical ring pieces 722 are respectively connected to a third pin 7221 and a fourth pin 7222 extending toward the support member 80. The third pin 7221 is disposed close to the support member 80. The second rotating body 721 is provided with a fourth through hole 7211 near the second electrical ring piece 722 away from the support member 80. The fourth pin 7222 extends from the inner side of the second rotating body 721 toward the top of the support member 80 through the fourth through hole 7211. The two leads at one end of the second wire 701 are respectively connected to the third pin 7221. Pin 7221 and the fourth pin 7222; the provision of third pin 7221 and fourth pin 7222 facilitates the connection of the second wire 701. If the first wire 601 is directly connected to the circuit board 52, the wire is too long and inconvenient to route, which is not conducive to the connection of the second wire 701. The third pin 7221 and the fourth pin 7222, which are respectively connected to the two second electrical rings 722, are integrally formed, so that the electrical rings and the pins are not easy to break. A through hole can be provided on the end of the third pin 7221 and the fourth pin 7222 away from the support, which facilitates the connection of the second wire 701. Figure 6 As shown.

[0031] In a further implementation of the second embodiment, the second electrical contact assembly 62 includes a second electrical contact block 621 and a second reset member 622. The second electrical contact block 621 abuts against the second electrical ring 722. One end of the second reset member 622 abuts against the groove wall of the second mounting groove 212, and the other end abuts against the second electrical contact block 621. A second mounting protrusion 6211 is provided at one end of the second electrical contact block 621 facing the second reset member 622, and the second reset member 622 is sleeved on the second mounting protrusion 6211. The second reset member 622 can be a spring, rubber, or an elastic sheet, but a spring is preferred because it is low in cost and has better elastic reset force. This makes the rotation of the second electrical ring 722 against the second electrical contact assembly 62 more stable, and the setting of the second mounting protrusion 6211 facilitates the installation of the second reset member 622.

[0032] Reference Figures 7-9In this embodiment, the first electrical connection assembly 60 and the second electrical connection assembly 70 are connected without wires in a third implementation. The front drive wheel assembly 21 has a second placement groove 213 on its top surface facing the support member 80. The second electrical connection assembly 70 includes a third rotating body 731 and two third electrical ring pieces 732. The third rotating body 731 is fixedly installed on the inner side of the support member 80 and sleeved on the steering wheel assembly 30, and rotatably located within the second placement groove 213. One third electrical ring piece 732 is installed on the outer side of the third rotating body 731, and the other third electrical ring piece 732 is installed on the bottom surface of the support member 80 facing the front drive wheel assembly 21. The two third electrical ring pieces 732 are disconnected. Two leads at one end of the conductor 701 are respectively connected to the two third electrical ring pieces 732. The first electrical connection assembly 60 includes two third electrical contact assemblies 63. The front drive wheel assembly 21 is provided with two fifth through holes 214. One fifth through hole 214 is disposed on the side wall of the second placement groove 213 corresponding to one of the third electrical ring pieces 732, and the other fifth through hole 214 is disposed on the top surface of the front drive wheel assembly 21 facing the support member 80 corresponding to the other third electrical ring piece 732. The front drive wheel assembly 21 is provided with two third mounting grooves 215 corresponding to the two fifth through holes 214. The two third electrical contact assemblies 63 are respectively installed in the two third mounting grooves 215, and the two third electrical contact assemblies 63 pass through the two fifth through holes 214 respectively. 14 abuts against the two third electric rings 732, and the two leads at one end of the first wire 601 are respectively connected to the two third electric contact assemblies 63; this structure means that the third rotating body 731 and the third electric ring 732 are mounted on the support 80, and the third electric contact assembly 63 is mounted on the front drive wheel set 21. The support 80 and the body assembly 10 do not rotate with the rotation of the steering wheel assembly. The steering wheel assembly 30 drives the front drive wheel set 21 to rotate, and the third electric contact assembly 63 rotates with the front drive wheel set 21. The first wire 601 also rotates with the front drive wheel set 21. In this way, when the steering wheel assembly drives the front drive wheel set 21, there will be no problem of wire entanglement. That is, the steering wheel assembly 21 can drive the front drive wheel set 21 to achieve a 360-degree rotation. The third embodiment uses an electrical connection method in which one third electrical ring 732 is disposed on the side wall of the third rotating body 731, and another third electrical ring 732 is disposed on the support member 80. This means that the two third electrical rings 732 are not disposed on the same part, but are disposed separately. Compared with the first and second embodiments, the electrical contact components of the first and second embodiments are disposed on the side of the rotating body, while in the third embodiment, one electrical contact component abuts against the side of the rotating body, and the other electrical contact component abuts against the bottom surface of the support member 80. The electrical contact components rotate with the steering wheel assembly driving the front drive wheel set to rotate. The third rotating body 731 is cylindrical in shape, and can be a cylindrical cylinder, so that the third electrical ring 732 can abut against the third electrical contact component 63 more smoothly during rotation.

[0033] The third embodiment described above is further implemented in which the two third electrical ring pieces 732 are respectively connected to a fifth pin 7321 and a sixth pin 7322 extending toward the top of the support member 80, and the two leads at one end of the second wire 701 are respectively connected to the fifth pin 7321 and the sixth pin 7322; the third contact assembly 63 includes a third contact block 631 and a third reset member 632, the third contact block 631 abuts against the third electrical ring piece 732, one end of the third reset member 632 abuts against the groove wall of the third mounting groove 215, and the other end abuts against the... The third electrical contact block 631 is equipped with a fifth pin 7321 and a sixth pin 7322, which facilitates the connection of the second wire 701. If the first wire 601 is directly connected to the circuit board 52, the wire is too long and inconvenient to route, making it difficult to connect the second wire 701. The fifth pin 7321 and the sixth pin 7322 connected to the two third electrical rings 732 are integrally formed, so that the electrical ring and the pin are not easily broken. A through hole can be provided on the end of the fifth pin 7321 and the sixth pin 7322 away from the support, which facilitates the connection of the second wire 701. Figure 8 As shown.

[0034] In a further implementation of the third embodiment, the third electrical contact block 631 has a third mounting protrusion 6311 at one end facing the third reset member 632, and the third reset member 632 is sleeved on the third mounting protrusion 6311. The third reset member 632 can be a spring, rubber, or elastic sheet, but a spring is preferred because it is low in cost and has better elastic reset force. This makes the contact rotation between the third electrical contact assembly 63 and the third electrical ring 732 more stable, and the setting of the third mounting protrusion 6311 facilitates the installation of the third reset member 632.

[0035] Reference Figures 10-12In this embodiment, the first electrical connection assembly 60 and the second electrical connection assembly 70 are connected without wires in a fourth implementation scheme. The first electrical connection assembly 60 includes a fourth rotating body 641 and two fourth electrical ring plates 642. The fourth rotating body 641 is sleeved on the steering wheel assembly 30 and installed on the front drive wheel assembly 21, and is rotatably located inside the support member 80. One fourth electrical ring plate 642 is installed on the outer side of the fourth rotating body 641, and the other fourth electrical ring plate 642 is installed on the top surface of the front drive wheel assembly 21 facing the support member 80. The two fourth electrical ring plates 642 are disconnected. The two leads at one end of the first wire 601 are respectively connected to the two fourth electrical ring plates 642. The second electrical connection assembly 70 includes two fourth electrical contact assemblies 74. The support member 80 has two fourth mounting grooves 84 corresponding to the two fourth electrical ring pieces 642, and each of the sidewalls of the two fourth mounting grooves 84 has a sixth through hole 841. One sixth through hole 841 faces the fourth rotating body 641, and the other sixth through hole 841 faces the sixth through hole 841 on the sidewall of the front drive wheel assembly 21. The two fourth electrical contact assemblies 74 are respectively installed in the two fourth mounting grooves 84, and the two fourth electrical contact assemblies 74 abut against the two fourth electrical ring pieces 642 through the two sixth through holes 841. Two leads at one end of the second conductor 701 are respectively connected to the two fourth electrical contact assemblies 74. This structure is... The fourth rotating body 641 and two fourth electric ring plates 642 are mounted on the front drive wheel assembly 21, and the fourth electric contact assembly 74 is mounted on the support member 80. The support member 80 and the body assembly 10 do not rotate with the steering wheel assembly. The steering wheel assembly 30 drives the front drive wheel assembly 21 to rotate, and the fourth rotating body 641 and the fourth electric ring plates 642 rotate with the front drive wheel assembly 21. The first wire 601 also rotates with the front drive wheel assembly 21. In this way, when the steering wheel assembly 21 drives the front drive wheel assembly 21, there will be no problem of wire entanglement. That is, the steering wheel assembly can drive the front drive wheel assembly 21 to achieve a 360-degree rotation. Compared with the third embodiment, the two electric ring plates are set separately, just like in the third embodiment. On the same component, a fourth electric ring 642 is mounted on the front drive wheel assembly 21, and a fourth electric ring 642 is mounted on the fourth rotating body 641. However, compared with the third embodiment, in the third embodiment, the rotating body moves with the support while the contact assembly rotates with the front drive wheel assembly, while in the fourth embodiment, the rotating body rotates with the front drive wheel assembly while the contact assembly moves with the support, which is the opposite of the third embodiment. The two leads at one end of the second conductor 701 and the two leads at one end of the first conductor 601 each have one positive lead and one negative lead, which is prior art and will not be described in detail here. The fourth rotating body 641 is cylindrical in shape and can be a cylindrical cylinder, so that the fourth electric ring 642 can rotate more smoothly with the fourth contact assembly 74.

[0036] In a further implementation of the fourth embodiment described above, the fourth electrical ring 642 disposed on the fourth rotating body 641 is connected to a seventh pin 6421 extending toward the interior of the front drive wheel assembly 21. Two leads at one end of the second conductor 701 are respectively connected to the seventh pin 6421 and another fourth electrical ring 642. The fourth contact assembly 74 includes a fourth contact block 741 and a fourth reset member 742. The fourth contact block 741 abuts against the fourth electrical ring 642, and one end of the fourth reset member 742 abuts against the groove wall of the fourth mounting groove 84, while the other end abuts against the fourth contact block 742. 1; A fourth electric ring plate 642 is provided with a seventh pin 6421. Since the fourth electric ring plate 642 is too far from the motor of the front drive wheel assembly 21, while another fourth electric ring plate 642 is directly set on the front drive wheel assembly 21, it can be directly connected to the lead wire. This arrangement makes it more convenient to connect the first wire 601. Of course, the other fourth electric ring plate 642 can also be provided with a pin. There is no restriction here. The seventh pin 6421 connected to the fourth electric ring plate 642 is integrally formed, so that the electric ring plate and the pin are not easy to break. A through hole can be provided on the end of the seventh pin 6421 away from the support, which facilitates the connection of the first wire 601. Figure 12 As shown; the fourth reset member 742 can be a spring, rubber or elastic sheet, but a spring is preferred because it is low in cost and has better elastic reset force. This makes the fourth contact assembly 74, which abuts against the fourth electric ring 642 disposed on the fourth rotating body, rotate more stably and has better elastic reset force.

[0037] In a further implementation of the fourth embodiment, the fourth electrical contact 741 has a fourth mounting protrusion 7411 at one end facing the fourth reset member 742, and the fourth reset member 742 is sleeved on the fourth mounting protrusion 7411. The setting of the fourth mounting protrusion 7411 facilitates the installation of the fourth reset member 742.

[0038] Reference Figures 13-14In this embodiment, a fifth implementation of the first electrical connection component 60 and the second electrical connection component 70 is described. Both the first electrical connection component 60 and the second electrical connection component 70 include a fifth electrical ring 671 and a fifth electrical contact component 761. A fifth mounting groove 280 is provided on both the support member 80 and the front drive wheel assembly 21. One fifth electrical ring 671 is mounted on the top surface of the front drive wheel assembly 21 facing the support member 80, and the fifth mounting groove 280 on the support member 80 corresponds to the fifth electrical ring 671 on the front drive wheel assembly 21. Another fifth electrical ring 671 is mounted on the bottom surface of the support member 80 facing the front drive wheel assembly 21, and the fifth mounting groove 280 on the front drive wheel assembly 21 corresponds to the fifth mounting groove 280 on the support member 80. Two fifth electrical contact components 761 are also provided. 1. The first wire 601 is respectively installed in the two fifth mounting slots 280. The two leads at one end of the first wire 601 are respectively connected to the fifth electrical ring 671 and the fifth electrical contact assembly 761 installed on the front drive wheel assembly 21. The two leads at one end of the second wire 701 are respectively connected to the fifth electrical ring 671 and the fifth electrical contact assembly 761 installed on the support member 80. Compared with the above four embodiments, this fifth embodiment does not have a rotating body. The two fifth electrical rings are respectively installed on the support member and the front drive wheel assembly, and the fifth electrical contact assemblies of the corresponding electrical rings are installed on the support member and the front drive wheel assembly, which is simpler in structure and lower in cost. Connection pins can be set on the fifth electrical rings, which makes it easier to connect the wires. Since the fifth electrical rings are directly installed on the support member and the front drive wheel assembly, the wires can also be directly connected to the fifth electrical rings. The distance is short and will not affect the connection.

[0039] In a further implementation of the fifth embodiment, the fifth electrical contact assembly 761 includes a fifth electrical contact block 675 and a fifth reset member 765. The fifth electrical contact block 675 abuts against the fifth electrical ring 671. One end of the fifth reset member 765 abuts against the groove wall of the fifth mounting groove 280, and the other end abuts against the fifth electrical contact block 675. The fifth reset member 765 can be a spring, rubber, or an elastic sheet, but a spring is preferred because it is low in cost and has better elastic reset force, so that the fifth electrical contact block 675 abuts against the fifth electrical ring better when rotating.

[0040] In a further implementation of the fifth embodiment, the fifth electrical contact 675 has a fifth mounting protrusion 6751 at one end facing the fifth reset member 765, and the fifth reset member 765 is sleeved on the fifth mounting protrusion 6751; the fifth mounting protrusion 6751 facilitates the installation of the fifth reset member 765; the fifth electrical contact 675 can be a block of copper.

[0041] Reference Figures 15-16In this embodiment, the first electrical connection component 60 and the second electrical connection component 70 are connected without wires in a sixth implementation. The second electrical connection component 70 includes two sixth electrical rings 76, both of which are disposed on the bottom surface of the support member 80 facing the front drive wheel assembly 21, and the two sixth electrical rings 76 are disconnected. Two leads at one end of the second wire 701 are respectively connected to the two sixth electrical rings 76. The first electrical connection component 60 includes two sixth electrical contact components 66. The front drive wheel assembly 21 is provided with two sixth mounting slots 217 corresponding to the two sixth electrical rings 76, and the two sixth electrical contact components 66 are respectively installed in the two sixth mounting slots 217. The first wire 601 has two leads at one end connected to the two sixth electrical contact assemblies 66, respectively, and is abutted against the two sixth electrical ring pieces 76. Compared with the first, second, third, and fourth embodiments, this sixth embodiment does not have a rotating body. Compared with the fifth embodiment, the arrangement is simpler. Both sixth electrical ring pieces 76 are set on the support member 80, and both sixth electrical contact assemblies 66 are set on the front drive wheel assembly 21. The electrical connection structure is simpler, the process is simplified, and the production efficiency is improved. Connection pins can be set on the sixth electrical ring pieces, which makes it easier to connect the wires. Since the sixth electrical ring pieces are directly set on the support member, the wires can also be directly connected to the sixth electrical ring pieces. The distance is short and will not affect the connection.

[0042] In a further implementation of the sixth embodiment, the sixth electrical contact assembly 66 includes a sixth electrical contact block 661 and a sixth reset member 662. The sixth electrical contact block 661 abuts against the sixth electrical ring 76. One end of the sixth reset member 662 abuts against the groove wall of the sixth mounting groove 217, and the other end abuts against the sixth electrical contact block 661. The sixth electrical contact block 661 has a sixth mounting protrusion 6611 at one end facing the sixth reset member 662, and the sixth reset member 662 is sleeved on the sixth mounting protrusion 6611. The sixth reset member 662 can be a spring, rubber, or an elastic sheet, but a spring is preferred because it is low in cost and has better elastic reset force, allowing the sixth electrical contact block 661 to better abut against the sixth electrical ring 76 when rotating. The setting of the sixth mounting protrusion 6611 facilitates the installation of the sixth reset member 662. The sixth electrical contact block 661 can be a block of copper.

[0043] In this embodiment, as Figure 5 As shown, the front drive wheel assembly 21 in the first, second, third, fourth, fifth, and sixth embodiments all include a motor 210 for driving the front drive wheel assembly and a housing 2100. The motor 210 is disposed inside the housing 2100, and the other end of the first wire 601 is connected to the motor.

[0044] In this embodiment, both leads at one end of the second conductor 701 and both leads at one end of the first conductor 601 have one positive lead and one negative lead, which is existing technology and will not be described in detail here.

[0045] In this embodiment, as Figures 18-24 As shown, the display component can display various cute expressions, further enhancing children's interest in electric scooters.

[0046] In this embodiment, six implementation schemes are provided for wireless electrical connection between the first electrical connection component 60 and the second electrical connection component 70. The structural design of the six implementation schemes facilitates the 360-degree rotation of the front drive wheel assembly, enhancing children's interest in the electric scooter. Furthermore, a support for the circuit board is provided to facilitate electrical connection with other electrical connection components. A display component is also provided to further enhance children's interest in the electric scooter and improve the user experience.
