The mounting plate 111 is vertically arranged, and the mounting plate 111 is an arc-shaped plate structure, and its arc surface fits the beam of the electric vehicle; there are two connecting seats 112, one end of which is respectively spaced and vertically arranged on the back of the mounting plate 111, and the other end is fixedly connected to the No. 2 gear clip 113; the clamping part of the No. 4 gear pipe clamp 114 is horizontally sleeved on the lower part of the mounting rod 12; the connecting surface of the No. 2 gear clip 113 and the No. 4 gear pipe clamp 114 is a face gear structure, which is through in the middle; the No. 4 gear pipe clamp 114 is meshed and connected with the two No. 2 gear clips 113 by bolts; the nut fixing sleeve of the bolt is provided with a handwheel.

[0055] The left end of the screw rod of the bolt horizontally passes through the No. 2 gear clip 113 and the No. 4 gear tube clamp 114 on the right side in sequence, and the face gears of the No. 2 gear tube clamp 32 and the No. 4 gear tube clamp 114 are meshed and connected by turning the hand wheel; when the hand wheel is turned to loosen the nut, the No. 4 gear tube clamp 114 can be rotated in the vertical plane based on the connection position with the No. 2 gear clip 113, thereby driving the mounting rod 12 to rotate; when the hand wheel is turned to tighten the nut, the connection position of the No. 4 gear tube clamp 114 and the No. 2 gear clip 113 will be pressed and fixed, and at the same time, the clamping part of the No. 4 gear tube clamp 114 is tightened to clamp the mounting rod 12.

[0056] There are multiple clamps 115, which are arranged at intervals in the vertical direction. The clamps 115 are sleeved on the mounting plate 111 and the vehicle beam to fix the mounting plate 111 and the vehicle beam; the mounting plate 111 is provided with a limiting connector, and a channel for accommodating the clamp 115 to pass through is provided between the limiting connector and the mounting plate 111. The clamp 115 passes through the limiting connector to fix the connecting plate and the vehicle beam, which is convenient for operation.

[0057] This embodiment is used for electric vehicles with exposed beams.

[0058] First, fit the arc surface of the mounting piece 111 of the mounting assembly 11 with the bottom end of the electric vehicle beam, and firmly connect the beam and the mounting piece 111 through multiple clamps 115; horizontally sleeve the No. 4 gear tube clamp 114 on the lower part of the mounting rod 12, and connect the connection positions at both ends of the No. 4 gear tube clamp 114 to the opposite sides of the No. 2 gear clip 113 through bolts, so that the face gears of the No. 4 gear tube clamp 114 and the No. 2 gear clip 113 are engaged; rotate the mounting rod 12 through the No. 4 gear tube clamp 114, adjust the mounting rod 12 to be perpendicular to the ground, tighten the bolts, press and fix the No. 4 gear tube clamp 114 and the No. 2 gear clip 113, and fix the mounting rod 12 at the same time.

[0059] S2: The front end of the riding mechanism 2 with the support rod 21 at the bottom is mounted on the mounting rod 12 in the front-to-back horizontal direction through the first connecting assembly 3. The mounting height of the riding mechanism 2 on the mounting rod 12 is adjusted according to the height of the driver and the passenger through the first connecting assembly 3. The riding mechanism 2 is also adjusted to be horizontal. The support rod 21 and the mounting rod 12 are then locked together through the first connecting assembly 3.

[0060] like Figure 5-6 As shown, the first connecting assembly 3 includes a No. 1 gear tube clamp 31 and a No. 2 gear tube clamp 32; the clamping portion of the No. 1 gear tube clamp 31 is horizontally sleeved on the mounting rod 12; the clamping portion of the No. 2 gear tube clamp 32 is vertically sleeved on the support rod 21; the connecting surface of the No. 1 gear tube clamp 31 and the No. 2 gear tube clamp 32 is a face gear structure with a through-hole in the middle, and the No. 1 gear tube clamp 31 is meshed and connected with the No. 2 gear tube clamp 32 by a bolt; the nut fixing sleeve of the bolt is provided with a hand wheel.

[0061] The screw rod of the bolt passes through the No. 2 gear tube clamp 32 and the No. 1 gear tube clamp 31 horizontally in sequence, and the nut is screwed into the screw rod by turning the hand wheel, thereby meshing the face gears of the No. 1 gear tube clamp 31 and the No. 2 gear tube clamp 32; when the hand wheel is turned to loosen the nut, the No. 2 gear tube clamp 32 can be rotated in the vertical plane based on the connection position with the No. 1 gear tube clamp 31, thereby driving the support rod 21 to rotate, and at the same time, the clamping part of the No. 1 gear tube clamp 31 is loosened, and the No. 1 gear tube clamp 32 is loosened. The wheel tube clamp 31 can rotate on the mounting rod 12, driving the support rod 21 to rotate on the horizontal plane; the clamping portion of the No. 2 gear tube clamp 32 is loosened, allowing the support rod 21 to rotate based on its own axis in the No. 2 gear tube clamp 32; when the handwheel is turned and the nut is tightened, the connection position of the No. 1 gear tube clamp 31 and the No. 2 gear tube clamp 32 will be pressed and fixed, and at the same time, the clamping portions of the No. 1 gear tube clamp 31 and the No. 2 gear tube clamp 32 are tightened to clamp the mounting rod 12 and the support rod 21.

[0062] The clamping part of the No. 1 gear tube clamp 31 is horizontally sleeved on the mounting rod 12, and the clamping part of the No. 2 gear tube clamp 32 is vertically sleeved on the front end of the support rod 21, and the left end of the No. 2 gear tube clamp 32 is connected to the right end of the No. 1 gear tube clamp 31 by bolts, so that the No. 2 gear tube clamp 32 is engaged with the No. 1 gear tube clamp 31. At the same time, according to the height of the driver and the passenger, the position of the No. 1 gear tube clamp 31 on the mounting rod 12 is moved to adjust the installation height of the riding mechanism 2 on the mounting rod 12 to ensure that the driver's line of sight is not obstructed; finally, the support rod 21 is rotated on the vertical plane through the No. 2 gear tube clamp 32, adjusted to be parallel to the ground, and the bolts are tightened to lock the support rod 21 and the mounting rod 12 to each other.

[0063] The riding mechanism 2 further includes a seat cushion 22 , which is disposed in the middle of the top surface of the support rod 21 .

[0064] The auxiliary rod is horizontally arranged along the left and right directions, and one end thereof is vertically arranged on the side of the middle part of the support rod 21. The seat cushion 22 is fixed on the support rod 21 and the auxiliary rod to improve stability.

[0065] S3: The lying protection mechanism 4 is installed at the rear end of the support rod 21 through the second connecting component 5. The lying protection mechanism 4 can be rotated and flipped forward and backward through the second connecting component 5. The angle between the lying protection mechanism 4 and the riding mechanism 2 is adjusted according to the riding needs of the passenger. The lying protection mechanism 4 and the riding mechanism 2 are then locked together through the second connecting component 5.

[0066] like Figure 7-8As shown, the lying protection mechanism 4 includes a fixed rod 41 and a protection frame 42; the lower part of the fixed rod 41 is connected to the top of the rear end of the support rod 21 through a second connecting component 5; the protection frame 42 is fixed on the fixed rod 41 along the left and right horizontal directions, and its two ends are bent forward.

[0067] The second connecting assembly 5 includes a No. 3 gear tube clamp 51, a No. 1 gear clip 52, and a base 53; the base 53 is vertically fixed on the top of the rear end of the support rod 21; the No. 1 gear clip 52 is vertically fixed on the top surface of the base 53; the clamping part of the No. 3 gear tube clamp 51 is horizontally sleeved on the lower part of the fixed rod 41; the connecting surface of the No. 1 gear clip 52 and the No. 3 gear tube clamp 51 is a face gear structure, which is through in the middle; the No. 3 gear tube clamp 51 is meshed and connected with the No. 1 gear clip 52 by bolts; the nut fixing sleeve of the bolt is provided with a handwheel.

[0068] The screw rod of the bolt passes horizontally through the No. 1 gear clip 52 and the No. 3 gear tube clamp 51 in sequence, and the nut is screwed into the screw rod by turning the hand wheel, so that the face gears of the No. 1 gear clip 52 and the No. 3 gear tube clamp 51 are meshed and connected; when the hand wheel is turned to loosen the nut, the No. 3 gear tube clamp 51 can be rotated in the vertical plane based on the connection position with the No. 1 gear clip 52, thereby driving the fixing rod 41 to rotate; when the hand wheel is turned to tighten the nut, the connection position of the No. 3 gear tube clamp 51 and the No. 1 gear clip 52 will be pressed and fixed, and at the same time, the clamping part of the No. 3 gear tube clamp 51 is tightened to clamp the fixing rod 41.

[0069] The clamping part of the No. 3 gear tube clamp 51 is sleeved on the lower part of the fixing rod 41, and the right end of the No. 3 gear tube clamp 51 and the left end of the No. 1 gear clip 52 provided at the rear end of the support rod 21 are connected by bolts, so that the No. 3 gear tube clamp 51 is engaged with the face gear of the No. 1 gear clip 52; according to the riding needs of the passenger, the fixing rod 41 is rotated on the vertical plane through the No. 3 gear tube clamp 51 to adjust the angle between the fixing rod 41 and the support rod 21. When the passenger is riding, the fixing rod 41 is rotated on the vertical plane through the No. 3 gear tube clamp 51 to adjust the fixing rod 41 and the support rod 21 to form a right angle; when the passenger needs to lie down, the fixing rod 41 is rotated on the vertical plane through the No. 3 gear tube clamp 51 to adjust the fixing rod 41 and the support rod 21 to form an obtuse angle of a certain angle, so that the passenger can lie on his back at this angle in the lying protection mechanism 4.

[0070] Since the space in the pedal area 73 of the electric vehicle is limited and the rotation angle of the fixing rod 41 is small, the bolt of the first connecting assembly 3 can be loosened to loosen the clamping part of the No. 1 gear pipe clamp 31, and the support rod 21 can be rotated a certain angle on the horizontal plane based on the fixing rod 41, so that the riding mechanism 2 and the lying protection mechanism 4 can be rotated out of the pedal area 73 to obtain a larger space, and the fixing rod 41 can be rotated backward to a larger angle, so that the passenger can obtain a larger lying angle and improve comfort.

[0071] To ensure safety during riding, when the support rod 21 is rotated, the maximum rotation angle of the support rod 21 should ensure that the protection frame 42 of the lying protection mechanism 4 does not exceed the length range of the electric vehicle handlebar, and the protection frame 42 of the lying protection mechanism 4 is located under the driver's arms and above the thighs, so that the driver's arms and thighs can protect the passengers during driving.

[0072] In order to facilitate the driver to get on the vehicle after adjustment, the support rod 21 should be rotated to the right.

[0073] S4: According to the installation height of the support rod 21, the length of the support mechanism 6 provided at the rear bottom of the support rod 21 is adjusted so that the lower end of the support mechanism contacts the top of the pedal area 73 of the electric vehicle.
