As shown in fig. 5, first, the first clamping portion 12 and the second clamping portion 22 clamp the handlebar stem 101 after abutting, and press the handlebar stem 101, thereby preventing the control unit 500 from sliding along the handlebar stem 101.

Second, the handle post 101 is provided with an upper stopper 103 for restricting the upward movement of the metal case 501 and a lower stopper 104 for restricting the downward movement of the metal case 501.

As shown in fig. 2 to 6, preferably, the upper retainer 103 is a first cross bar 103 fixed between the two handle bars 101, the lower retainer 104 is a second cross bar 104 fixed between the two handle bars 101, the first cross bar 103 abuts against an upper end surface of the first clamping portion 12 and/or the second clamping portion 22, and the second cross bar 104 abuts against a lower end surface of the first clamping portion 12 and/or the second clamping portion 22. The first beam and the second beam are parallel to each other. They not only play the limiting action to the control unit 500, but also strengthen the connection between two handlebar upright posts 101 of the front body unit 100, strengthen the strength of the front body unit 100, and make the structure of the electric scooter more stable.

That is, the first cross bar 103 includes two first fixing portions 31 connected to the handlebar stem 101 and a middle first bent portion 32, and a lower side of the first bent portion 32 forms a protruding portion M. The lower end surface of the first fixing portion 31 abuts against the upper end surfaces of the first clamping portion 12 and the second clamping portion 22, so that the metal box 501 is limited at the upper side. Further preferably, the first bent portion 32 and the upper end of the metal case 501 are further fixed by a screw.

Further preferably, the outer side of the first clamping part 12 has a structure protruding toward the second clamping part 22, and correspondingly, the second clamping part 22 has a structure matching with the concave structure, so that the two are clamped to limit the relative sliding. And the receiving groove T where the turn signal lamp 900 is installed is provided on the outer wall of the first nip portion 12, and the cable passage 4, the first wire hole and the second wire hole are all provided on the inner wall of the first nip portion 12. Therefore, the protective cover 502 and the metal box 501 can be separated conveniently, the control unit 500 can be mounted more conveniently, and a user can detach the control unit 500 from the vehicle body for independent maintenance.

Further preferably, as shown in fig. 11, the bar-shaped turn signal lamp 900 includes a bar-shaped base 901, a light bar element 902, and a bar-shaped light shade 903. The strip-shaped bottom plate 901 is fixed in the accommodating groove T through screws, the light bar element 902 is clamped in the installing groove T of the strip-shaped bottom plate 901, and the strip-shaped lampshade 903 is buckled outside the strip-shaped bottom plate 901 and the light bar element 902.

As shown in fig. 9-10, a mounting bracket 78 is fixed to the front side of the shield portion of the shield cover 502, and a searchlight 700 and a horn 800 are connected to the mounting bracket 78.

The mounting bracket 78 is a sheet metal member bent forward at both ends. Wherein the first connecting member 81 of the horn 800 is sandwiched between the middle section 78a of the sheet metal member and the shield cover 502, and the three are fixed by screws. The body of the horn 800 is located below the mounting bracket 78 and in the area below the shield cover 502.

In addition, the bent section 78b of the sheet metal part is connected to the second connecting member 71 of the floodlight 700. The searchlight 700 extends to the front side of the mounting bracket 78 so that the light source irradiates the front area of the electric scooter.

It should be noted that, in the above description, the metal box 501 and the protective cover 502 may be made of metal material with certain strength and heat dissipation capability. Preferably, an aluminum material which is easy to mold and has excellent heat conductivity is used for die casting.

In order to make the control unit 500 have excellent heat dissipation performance, so that the temperature of the controller D is stable, and the stability of the controller D is ensured, the heat dissipation system of the control unit 500 is optimized in this embodiment, and the heat dissipation system of the controller D box with the protective cover 502 is described in detail below.

As shown in fig. 5 and 7 to 15, as described above, the outer surface of the metal case 501 accommodating the controller D is partially covered with the protective cover 502, and the protective cover 502 may cover only the first wall of the metal case 501. In this embodiment, the protective cover 502 is disposed on the front side of the metal box 501, i.e., the front wall of the metal box 501. The protective cover 502 is provided with at least one air inlet 1 communicated with the heat dissipation gap between the inner surface of the protective cover 502 and the outer surface of the metal box 501, and external air flow enters the heat dissipation gap from the air inlet 1 to exchange heat with the outer surface of the metal box 501.

It should be clear that the controller D itself achieves heat dissipation by virtue of the metal box 501 conducting heat. In this embodiment, the controller D is attached to the front wall of the metal case 501, and the heat of the controller D is conducted to the metal case 501, and a part of the heat is dissipated by the surface of the metal case 501, and the heat is further conducted to the handle stem 101 because the metal case 501 is connected to the handle stem 101. In this way, the temperature of the controller D is controlled.

It should also be understood that, during the forward riding of the electric scooter, there is a strong backward airflow, which enters the heat dissipation gap from the air inlet 1 at the front side of the protecting cover 502 and flows out from the negative pressure gap after cooling the surface of the metal box 501 in the heat dissipation gap, thereby achieving the air cooling effect.

Preferably, as shown in fig. 7, 8 and 13, the outer surface of the front wall of the metal box 501 is provided with a first heat dissipation part S1 extending outward, and the gas inlet 1 of the protective cover 502 corresponds to the first heat dissipation part S1, so that at least a part of the first heat dissipation part S1 is exposed from the gas inlet 1.

The arrangement can lead the heat of the metal box 501 out of the protective cover 502 and lead the external air flow into the protective cover 502, so that the metal box 501 and the external air generate heat exchange, the heat dissipation of the controller D is accelerated, and the operation stability and the efficiency of the controller D are improved.

As shown in fig. 7, the protecting cover 502 is provided with an air inlet 10 protruding outward, the air inlet 10 is located in a lower section area of the protecting cover 502, and the air inlet 1 is located on a lower end surface of the air inlet 10. The air inlet 1 is arranged in the lower section area of the protective cover 502, the air inlet 1 is arranged on the lower end face of the air inlet part 10, cold air is fully utilized, hot air is far away from the upper part, cold air enters the heat dissipation gap from the air inlet 1, and the cold air flows upwards after heat exchange and flows out from the gap between the metal box 501 and the protective cover 502.

Preferably, as shown in fig. 7, 8 and 13, the shape of the air inlet 10 is matched with the contour of the outer periphery of the first heat sink member S1, the outer periphery of the first heat sink member S1 is attached to the inner wall of the air inlet 10, and the first heat sink member S1 has an air inlet passage. This makes heat conduction between the outer periphery of the first heat dissipating part S1 and the shield cover 502 more efficient, and external airflow can enter and exit from the air intake passage.

The first heat dissipation part S1 is a plurality of ridge-shaped ribs laterally arranged side by side at intervals, the ridge-shaped ribs increase the surface area of the metal box 501, thereby increasing the heat dissipation, and the air inlet passages are formed between the adjacent ribs.

In this embodiment, as shown in fig. 13, the air inlet portion 10 includes a slope H inclined from top to bottom and from inside to outside, and the first heat sink portion S1 is also formed in an inclined structure matching therewith. Such an arrangement can prevent dirt from entering the heat dissipation gap to affect heat dissipation. The rainwater can also drop along the inclined surface, and the rainwater is prevented from flowing down along the protecting cover 502 shell and flowing into the accommodating chamber F from the wire passing hole O2 of the metal box 501. Thus, a dustproof and waterproof structure is skillfully formed.

Preferably, in the present embodiment, there are two air inlets 10 symmetrically disposed along the longitudinal center line of the shield cover 502, and there are two corresponding first heat dissipation parts S1.

As shown in fig. 13 and 15, the outer surface of the front wall of the metal box 501 is provided with a second heat sink part, and the second heat sink part is located in the heat sink gap for further enhancing the heat sink effect of the metal box 501. As can be clearly seen from the figure, the second heat sink members are dot-shaped projections distributed in an array. The second heat sink member is positioned over the first heat sink member S1, which also follows the principle of heat transfer from the air flow moving from bottom to top.

It is further preferable that, as shown in fig. 7 and 12, a third heat sink portion S3 is disposed on an inner wall of the socket hole O1 enclosed by the two sides of the metal box 501 and the protective cover 502 together, so as to further improve heat dissipation of the controller D. In this embodiment, the third heat dissipating part S3 is a concave-convex structure disposed on the inner wall of the second clamping part 22 of the protecting cover 502 close to the protecting plate and distributed in parallel in the longitudinal direction. When the first nip portion 12 and the second nip portion 22 are butted, a portion of the concavo-convex configuration near the shield plate realizes heat conduction between the metal box 501 and the shield cover 502 against the metal box 501. Meanwhile, it is easily understood that the provision of the concavo-convex structure further increases the frictional force between the socket part K2 and the handle stem 101, further prevents the control unit 500 from moving, and reinforces the connection of the control unit 500.

As shown, the present embodiment also provides an internal structure of the control unit 500, thereby forming a control system of the electric scooter convenient for maintenance.

Specifically, as shown in fig. 8, 12 and 16, a longitudinal partition plate 40 is provided in the housing of the metal case 501. The partition plate 40 divides the accommodating chamber F into a first chamber and a second chamber, and the wire passing hole O2 at the lower portion of the metal box 501 communicates with the second chamber. At least one controller D is fixedly arranged in the first cavity. A wire collecting box 30 is fixedly arranged in the second cavity, a plug-in input terminal group and an output terminal group are arranged in the wire collecting box 30, a lead-out cable of the controller D is connected with the input terminal group, and an external cable Q including a storage battery cable penetrates through the wire passing hole O2 to be connected with the output terminal group, so that the electric connection and the signal connection between the controller D and external electric components are realized.

The junction box 30 not only realizes the switching between the external electric components and the controller D, but also adopts the pluggable input terminal group and the pluggable output terminal group, so that the circuit connection is more convenient and faster.
