[0021] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments.

[0022] The utility model discloses an electric crawler scooter, combined with Figures 1 to 5 As shown, it includes a pedal 1, a steering arm 2 is provided at the front end of the pedal 1, a steering arm 2 is connected to the upper end of the steering arm 2, a front fork 8 is provided at the lower end of the steering arm 2, a slide plate 4 is provided at the lower end of the front fork 8, a rear fork 5 is provided at the rear end of the pedal 1, an electric crawler mechanism 6 is provided between the two fork rods of the rear fork 5, and a control mechanism 7 for controlling the operation of the electric crawler mechanism 6 is provided on the steering arm 3.

[0023] In the above structure, the pedal 1, the steering arm 2 and the steering armrest 3 form the main structure of the scooter. On this basis, the skateboard 4 is installed at the lower end of the steering arm 2, and the front and rear ends of the skateboard 4 are tilted, and can rotate with the steering armrest 3 and the steering arm 2, so as to achieve the function of controlling the direction. At the same time, an electric crawler mechanism 6 is installed between the two fork rods of the rear fork 5, and the operation state of the electric crawler mechanism 6 is controlled by the control mechanism 7 on the steering armrest 3. The scooter based on the above structure uses the electric crawler mechanism as the power source, and uses the skateboard 4 as the front end support and used to control the direction, so that the utility model electric crawler scooter can better meet the various soft environments such as sand, snow, and grass. At the same time, because the front fork 8 and the rear fork 5 themselves are components that can be matched with wheels, when the user needs to drive on a hard road, he only needs to remove the skateboard 4 from the front fork 8 and replace the front wheel, and remove the electric crawler mechanism 6 from the rear fork 5 and replace the electric rear wheel. The replacement process is simple and convenient, so it is more versatile.

[0024] In this embodiment, a front fork 8 is provided at the lower end of the steering arm 2 , and a hinge assembly 40 is provided on the slide plate 4 . The hinge assembly 40 is installed between two fork rods of the front fork 8 .

[0025] Combination Figures 2 to 4 As shown, in this embodiment, the hinge assembly 40 includes a support 400, the support 400 is fixedly connected to the front fork 8 near the middle, the lower end of the support 400 is hinged to the skateboard 4, and a first shock absorber 401 is hinged between the front side of the support 400 and the position near the front end of the skateboard 4. The support 400 is used to support the skateboard 4 and enable the skateboard 4 to slightly flip and move, so as to cope with potholes, sand and snow environments. By providing the first shock absorber 401, the stress fed back by the skateboard 4 can be reduced.

[0026] Regarding the preferred fixing relationship of the support 400, in this embodiment, a fixed shaft 80 is provided on the support 400, and both ends of the fixed shaft 80 are fixedly connected to the front fork 8. The size of the fixed shaft 80 is the same as the axle size of the front wheel adapted to the scooter, so as to facilitate the replacement of the scooter and the front wheel.

[0027] As a preferred embodiment, the steering arm 2 and the front fork 8 are hingedly connected via a front fork shaft assembly 81, and a second shock absorber 82 is hingedly connected between the steering arm 2 and the front fork 8. In this embodiment, the second shock absorber 82 is provided to further reduce the vibration of the skateboard 4.

[0028] In order to reliably support and fix the support 400, in this embodiment, two auxiliary fixing arms 402 extending backward are provided on the rear side of the support 400, and the two auxiliary fixing arms 402 are respectively fixedly connected to the two fork rods of the front fork 8. Among them, by providing two auxiliary fixing arms 402 on the rear side of the support 400, the support 400 can be fixed from both sides, so that the fixing relationship between the support 400 and the front fork 8 is more reliable.

[0029] On this basis, the rear end of the auxiliary fixing arm 402 is formed with a bent portion 403 bent outward, and the two bent portions 403 are respectively overlapped on the top of the two fork rods of the front fork 8, and the bent portions 403 are fixedly connected to the fork rods of the front fork 8. In the above structure, please refer to Figure 4 The auxiliary fixing arm 402 is a thinner sheet-shaped arm that plays an auxiliary fixing role. The two bent portions 403 are respectively overlapped with the two fork rods of the front fork 8, so that the two auxiliary fixing arms 402 can fit the inner side of the fork rod and extend backward. The two fork rods of the front fork 8 are used to hide and shield the two auxiliary fixing arms 402, so as to prevent the two auxiliary fixing arms 402 from being scratched or broken by external forces. At the same time, the two outward-turned bent portions 403 can cooperate more closely with the two fork rods of the front fork 8, and it is convenient to fix the bent portions 403 and the fork rods with screws.

[0030] Combination Figure 2 and Figure 5 As shown, in order to provide shock-absorbing effect to the rear fork 5 , in the present embodiment, the front end of the rear fork 5 is hingedly connected to the pedal 1 via a rear fork shaft assembly 50 , and a third shock absorber 51 is hingedly connected between the pedal 1 and the rear fork 5 .

[0031] As a preferred embodiment, the electric crawler mechanism 6 includes a crawler 60, a crawler motor 61 and a driven wheel 62. The crawler motor 61 and the driven wheel 62 are both arranged on the inner side of the crawler 60, and the crawler motor 61 and the driven wheel 62 are both in transmission cooperation with the crawler 60. The main shaft of the crawler motor 61 is connected between the two fork rods of the rear fork 5.

[0032] Among them, the main shaft of the crawler motor 61 is the same size as the main shaft of the electric rear wheel of the ordinary scooter, so both can be installed between the two fork rods of the rear fork 5. In this embodiment, based on the transmission effect of the crawler motor 61 and the driven wheel 62, the crawler 60 can be driven to operate, thereby realizing the walking function of the electric crawler scooter. At the same time, in this embodiment, the crawler motor 61 is preferably directly arranged on the inner side of the crawler 60, without the need to set up a transmission mechanism such as gears and chains. Therefore, the overall structure of the electric crawler mechanism 6 is simpler, which is convenient for design and manufacturing, and is easy to replace with an ordinary electric wheel.

[0033] In order to further strengthen the supporting and fixing effects, in the present embodiment, side plates 63 are respectively provided on the left and right sides of the crawler track 60 , the crawler track motor 61 and the driven wheel 62 are both installed between the two side plates 63 , and a support plate 64 is fixed between the tops of the two side plates 63 .

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
