[0024] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] See also Figure 1 as well as Figure 2 As shown, the present invention discloses an electric kart 200, comprising a front wheel assembly 210, a rear wheel assembly 220, a battery compartment assembly 230, a frame assembly 240 and a cradle assembly 250. The cradle assembly 250 is pivotally mounted on the frame assembly 240. The front wheel assembly 210 is directly or indirectly fixedly mounted on one end of the frame assembly 240 away from the cradle assembly 250. The rear wheel assembly 220 is directly or indirectly fixedly mounted on the cradle assembly 250. In this embodiment, the rear wheel assembly 220 is a hub motor wheel.

[0026] The battery compartment assembly 230 is mounted on one end of the frame assembly 240 close to the cradle assembly 250. Preferably, the battery compartment assembly 230 is fixedly mounted on the frame assembly 240 by means of shock-absorbing screws. Such a configuration can fully ensure the stability of the contact between the battery pack and the electrode, thereby avoiding the occurrence of adverse consequences such as spark erosion and relative wear of the contact parts.

[0027] Compared with the prior art, since the battery compartment assembly 230 is directly fixedly mounted on the frame assembly 240 , the buffering swing range of the cradle assembly 250 is not affected.

[0028] In other preferred embodiments, please refer to Figure 1 , Figure 2 as well as Figure 3 As shown, the frame assembly 240 includes a bottom frame 241 and a side frame 242. The battery compartment assembly 230 is fixedly mounted on the side of the side frame 242 facing the cradle assembly 250. Preferably, the electric kart 200 also includes a seat 260. The seat 260 includes a cushion 261 and a backrest 262. The cushion 261 is fixedly mounted on the bottom frame 241, and the backrest 262 is arranged opposite to the side frame 242. The backrest 262 and the battery compartment assembly 230 are respectively located on both sides of the side frame 242.

[0029] Furthermore, the frame assembly 240 also includes a bracket 243 fixedly mounted on the side frame 242. The bracket 243 extends outwardly from the side frame 242 and is located above the cradle assembly 250. The battery compartment assembly 230 is fixedly mounted on the bracket 243. Such an arrangement not only ensures that the battery compartment assembly 230 does not affect the buffering swing range of the cradle assembly 250, but also makes the structure of the electric kart 200 compact without additionally extending the length or width of the electric kart 200. Preferably, the battery compartment assembly 230 is fixedly mounted on the bracket 243 by a shock-absorbing screw 245. Such an arrangement can fully ensure the stability of the contact between the battery pack and the electrode, thereby avoiding adverse consequences such as spark erosion and relative wear of the contact parts.

[0030] In this embodiment, the frame assembly 240 further includes a mounting seat 244 (eg Figure 3 As shown). The battery compartment assembly 230 is fixedly mounted on the mounting seat 244. The mounting seat 244 is fixedly mounted on the bracket 243 by a shock-absorbing screw 245. In this embodiment, the shock-absorbing screw 245 is a shock-absorbing stud screw. Of course, it can be understood that in other embodiments, the shock-absorbing screw 245 can also be other structures, which will not be repeated here.

[0031] In other preferred embodiments, please refer to Figure 3 as well as Figure 4 As shown, the cradle assembly 250 also includes a cradle 251 and a pair of shock absorbers 252. The cradle 251 is pivotally mounted on the frame assembly 240. One end of the shock absorber 252 is fixedly mounted on the frame assembly 240, and the other end is fixedly mounted on the cradle 251. With such a configuration, the shock absorber 252 can be used to better reduce the shock of the battery compartment assembly 230, thereby fully ensuring the stability of the contact between the battery pack and the electrode, thereby avoiding the occurrence of ignition erosion, relative wear of the contact parts and other adverse consequences. Preferably, the battery compartment assembly 230 is located between the pair of shock absorbers 252.

[0032] For further information, see Figure 5 As shown, the cradle assembly 250 further includes a buffer sleeve 253. The cradle 251 is pivotally mounted on the frame assembly 240 through the buffer sleeve 253. With such a configuration, the buffer sleeve 253 can be used to better reduce the shock of the battery compartment assembly 230, thereby fully ensuring the stability of the contact between the battery pack and the electrode, thereby avoiding the occurrence of adverse consequences such as spark erosion and relative wear of the contact parts.

[0033] In other preferred embodiments, please refer to Figure 4 as well as Figure 7As shown, the battery compartment assembly 230 includes a battery compartment 231. When the electric kart 200 is placed on a horizontal plane, the distance H1 between the center of gravity A of the battery compartment 231 and the horizontal plane is between 300 mm and 550 mm. Preferably, the battery compartment assembly 230 also includes a battery pack 232 accommodated in the battery compartment 231. When the electric kart 200 is placed on a horizontal plane, the distance H2 between the center of gravity B of the battery compartment assembly 230 and the horizontal plane is between 400 mm and 550 mm.

[0034] For further information, see Figure 4 As shown, the battery compartment 231 includes a compartment body 2311 and a compartment cover 2312 pivotally mounted on the compartment body 2311. The compartment body 2311 and the compartment cover 2312 together constitute a receiving cavity to receive the battery pack 232. Compared with the prior art, since the compartment cover 2312 is pivotally mounted on the compartment body 2311, the user can replace the battery pack 232 by opening the compartment cover 2312.

[0035] For further information, see Figure 7 As shown, the battery pack 232 is inserted into the battery compartment 231 along the first direction CC. When the electric kart 200 is placed on a horizontal plane, the angle between the first direction CC and the horizontal plane is α; wherein the angle α is between 22° and 90°.

[0036] In summary, the electric go-kart 200 of the present invention is not only convenient for users to replace the battery pack independently, but also does not affect the buffer swing range of the cradle 251 .

[0037] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention.
