[0019] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0020] like Figure 1As shown, a multi-mode drive electric beach vehicle includes a front body 1 and a rear body 2. One end of the front body 1 is fixedly connected to a connecting component 3, and the front body 1 and the rear body 2 are rotatably connected through the connecting component 3. An adjustment component 4 for adjusting the connection angle between the front body 1 and the rear body 2 is provided between the front body 1 and the rear body 2, and a power supply 5 is fixedly installed at the bottom end of the front body 1.

[0021] According to the above structure, when in use, the angle of the connection between the front body 1 and the rear body 2 is adjusted by adjusting the component 4 according to the flatness of the beach, thereby adjusting the height of the raised end of the front body 1, changing the height between the bottom end of the power supply 5 and the ground, and avoiding friction between the power supply 5 and the beach.

[0022] like Figure 4 As shown, the rear body 2 includes a rear body frame 21, one end of the rear body frame 21 is rotatably connected to a rotating shaft 22, and wheels 23 are fixedly installed at both ends of the rotating shaft 22. The top of the rear body frame 21 is fixedly connected to a protective box 25, and a reduction box 26 is provided inside the protective box 25. A motor 27 is provided on one side of the reduction box 26, and the output shaft of the motor 27 is fixedly connected to the input end of the reduction box 26. The output end of the reduction box 26 and the middle of the rotating shaft 22 are both provided with a bevel gear 24, and the two bevel gears 24 are meshed and connected.

[0023] According to the above structure, when in use, the motor 27 drives the rotating shaft 22 to rotate through the reduction box 26, and the rotating shaft 22 drives the wheels 23 to rotate, thereby driving the entire beach vehicle forward.

[0024] like Figure 3 and 4 As shown, the connecting assembly 3 includes a connecting shaft 31 fixedly connected to one end of the rear body frame 21, and a cylinder 32 is symmetrically fixedly connected to one end of the front body 1. The two ends of the connecting shaft 31 are respectively rotatably connected to the inside of the two cylinders 32, and the two ends of the side wall of the connecting shaft 31 are respectively provided with a torsion spring 33. One end of the torsion spring 33 is fixedly connected to the side wall of the connecting shaft 31, and the other end of the torsion spring 33 is fixedly connected to the inner wall of the corresponding cylinder 32.

[0025] According to the above structure, when connected, the cylinder 32 is fixedly connected to one end of the front body 1, and the rear body frame 21 is rotatably connected to the cylinder 32 through the connecting shaft 31. The beach car is placed on the ground, and under the influence of its own weight, the torsion spring 33 is tightened. When the angles of the front body 1 and the rear body 2 are adjusted, the restoring force of the torsion spring 33 can reduce the driving force required for the adjustment component 4.

[0026] like Figure 2 and 4As shown, the adjustment component 4 includes two symmetrically arranged hydraulic cylinders 41, one end of the hydraulic cylinder 41 is rotatably connected to the top of the front vehicle body 1, and the other end of the hydraulic cylinder 41 is rotatably connected to the middle of the rear vehicle body frame 21. A hydraulic station 42 for driving the hydraulic cylinder 41 to extend and retract is provided on the top of the rear vehicle body frame 21, and the motor 27 and the hydraulic station 42 are electrically connected to the power supply 5 through switches respectively.

[0027] According to the above structure, when adjusting the angle, the hydraulic cylinder 41 is driven to extend and retract through the hydraulic station 42, and the rear body frame 21 is rotated around the axis of the cylinder 32 through the connecting shaft 31, thereby adjusting the height of the end bulge where the front body 1 and the rear body frame 21 are connected.

[0028] The working principle of the present utility model is as follows: when in use, the angle of the connection between the front body 1 and the rear body 2 is adjusted according to the flatness of the beach through the adjustment component 4, thereby adjusting the height of the raised end of the front body 1, changing the height between the bottom of the power supply 5 and the ground, and avoiding friction between the power supply 5 and the beach. When in use, the motor 27 drives the rotating shaft 22 to rotate through the reduction gear 26, and the rotating shaft 22 drives the wheel 23 to rotate, thereby driving the entire beach vehicle forward. When connected, the cylinder 32 is fixedly connected to one end of the front body 1, and the rear body frame 21 is rotatably connected to the cylinder 32 through the connecting shaft 31. The beach vehicle is placed on the ground. Under the influence of its own weight, the torsion spring 33 is tightened. When the angle of the front body 1 and the rear body 2 is adjusted, the restoring force of the torsion spring 33 can reduce the driving force required by the adjustment component 4. When adjusting the angle, the hydraulic cylinder 41 is driven to retract and retract through the hydraulic station 42, and the rear body frame 21 rotates around the axis of the cylinder 32 through the connecting shaft 31, thereby adjusting the height of the raised end connected to the front body 1 and the rear body frame 21.
