[0045] Furthermore, the overall length of the actuator can be adjusted to support the risers at different installation angles, thereby achieving angle adjustment of the risers to meet the gripping angle requirements of different users and improve comfort.

[0046] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0047] To facilitate the description of the embodiments of the present application, the coordinate system shown in the accompanying drawings is first described, wherein the X-axis direction is the first direction, which may be the front and rear direction of the scooter, and this direction is consistent with the forward and backward directions of the scooter. The Y-axis direction is the second direction, which may be the left and right direction of the scooter, and the second direction is perpendicular to the first direction; the Z-axis direction is the third direction, which is the height direction of the scooter, and the third direction is perpendicular to the plane formed by the first and second directions.

[0048] like Figure 1 and Figure 2 As shown, the mobility scooter 100 provided in the embodiment of the present application includes a handlebar assembly 10, a chassis 20, a seat support frame 30, a seat bracket 40, a steering mechanism and a running mechanism, wherein the chassis 20 serves as a load-bearing unit, and the handlebar assembly 10, the seat bracket 40, the running mechanism and the steering mechanism are all installed on the chassis 20.

[0049] Specifically, the handlebar assembly 10 is arranged at the front end of the chassis 20 along the first direction and is connected to the steering mechanism, and the steering mechanism is linked with the running mechanism to control the travel direction of the scooter 100. Along the first direction, the seat support frame 30 is arranged at the rear end of the chassis 20 and is connected to the chassis 20 through the seat bracket 40. The seat support frame 30 is installed with a seat cushion, which supports the driver; the seat support frame 30 and the handlebar assembly 10 are arranged opposite to each other, and a seating space for the driver is formed between the two.

[0050] In the embodiment of the present application, the mobility scooter 100 is foldable. Along the second direction, seat brackets 40 are respectively provided on both sides of the chassis 20, and the chassis 20 is provided with supports corresponding to the seat brackets 40. Both ends of each seat bracket 40 are respectively connected to the supports and the seat support frame 30 to form a foldable mechanism.

[0051] When the scooter 100 is in the unfolded state, the seat support frame 30 is located at the rear end of the chassis 20 along the first direction and maintains a certain distance from the handlebar assembly 10; the seat support frame 30 is located above the chassis 20 along the third direction and maintains a certain space. This arrangement makes it easier for users to sit and operate the handlebar assembly 10.

[0052] The handlebar assembly 10 provided in the embodiment of the present application is connected to the steering mechanism, and the steering mechanism is transmission-connected to the running mechanism. Figure 3 As shown, the handlebar assembly 10 includes a handlebar 11 , a stem 12 and a steering seat 13 . The stem 12 extends along a third direction, and a top end of the stem 12 is connected to the handlebar 11 .

[0053] For example, the handle 11 is a horizontal handle, which is connected to the top of the stand pipe 12 to form a T-shaped structure. The bottom end of the stand pipe 12 is connected to the steering seat 13 to form a first hinge point, so that the stand pipe 12 can be rotated forward and backward along the first direction to adjust the inclination angle of the stand pipe 12.

[0054] The steering seat 13 is connected to the steering mechanism to drive the steering mechanism to move. The steering mechanism includes a steering rod and a steering arm connected thereto, one end of the steering arm is connected to the steering rod, and the other end of the steering arm is connected to the running wheel of the running mechanism. When the steering mechanism moves, the running wheel can be driven to turn.

[0055] For example, the walking mechanism includes a front wheel group and a rear wheel group, wherein the front wheel group is arranged at the front end of the chassis 20, and the front wheel group includes two front wheels 50. Along the second direction, the two front wheels 50 are arranged on the left and right sides of the chassis 20, and the two front wheels 50 are respectively connected to the steering arms and can steer synchronously.

[0056] The rear wheel group is arranged at the rear end of the chassis 20, and the rear wheel group includes two rear wheels 60. The two rear wheels 60 are arranged on both sides of the chassis 20 along the second direction, and the rear wheels 60 are connected to the driving mechanism of the all-terrain vehicle. The driving mechanism can be a driving motor, and the driving motor provides power to the rear wheels 60 to make the scooter 100 move forward, backward, etc.; that is, in the embodiment of the present application, the rear wheels 60 are driving wheels, and the front wheels 50 are configured as driven wheels.

[0057] Continue reading Figure 3 The handlebar assembly 10 provided in the embodiment of the present application further includes an actuating member 14, which is disposed on one side of the seat tube 12. For example, the actuating member 14 is disposed on the rear side of the seat tube 12, that is, the actuating member 14 is disposed on the side of the seat tube 12 facing the seat support frame 30. Furthermore, since the seat tube 12 is hinged to the steering seat 13, after the inclination angle of the seat tube 12 is adjusted, it is necessary to support it through the actuating member 14 to fix the adjusted position of the seat tube 12.

[0058] In the embodiment of the present application, the actuator 14 extends along the third direction, and the bottom end of the actuator 14 is hinged to the steering seat 13 to form a second hinge point, and the second hinge point is located on the side of the steering seat 13 facing the seat support frame 30. The top end of the actuator 14 is hinged to the standpipe 12 to form a third hinge point, and the third hinge point is located above the second hinge point, and the first hinge point, the second hinge point and the third hinge point are arranged in a triangle.

[0059] Furthermore, the overall length of the actuator 14 is adjustable. For example, at least one end of the actuator 14 is retractable to adjust the overall length of the actuator 14. When the installation angle of the riser 12 needs to be adjusted, the locking state of the actuator 14 is first released. During the adjustment of the installation angle of the riser 12, the overall length of the actuator 14 changes to provide support for the riser 12.

[0060] On the contrary, when the installation angle of the seat tube 12 is adjusted, the actuator 14 is locked so that the actuator 14 can effectively support and fix the seat tube 12 to prevent the handlebar assembly 10 from rotating accidentally during use.

[0061] Compared with the solution in the related art in which the installation angle of the handlebar assembly of the mobility scooter is fixed, which cannot meet the different requirements of users for holding angles and affects comfort, the mobility scooter provided in the embodiment of the present application has an overall length of the actuator 14 that is adjustable, can support the seat tube 12 at different angles, and can realize the angle adjustment of the handlebar assembly 10 to meet the requirements of different users for the angle of holding the handle and improve comfort.

[0062] like Figure 4 As shown, the steering seat 13 provided in the embodiment of the present application includes a body 131 and a first connecting portion 132 , wherein the first connecting portion 132 is arranged at the top of the body 131 along the third direction, and the first connecting portion 132 is used to be hinged to the bottom end of the standpipe 12 .

[0063] Exemplarily, the body 131 is configured as a cylinder, the bottom end of the body 131 is inserted into the steering rod of the steering mechanism, and the body 131 can rotate synchronously with the steering rod. The first connecting portion 132 is arranged at the top of the body 131, and the first connecting portion 132 includes two first mounting ears, the two first mounting ears are arranged oppositely at the top of the body 131, and the two first mounting ears are arranged at intervals to form an insertion space for the standpipe 12. The bottom end of the standpipe 12 is inserted between the two first mounting ears and is respectively hinged to the first mounting ears, so that the standpipe 12 can rotate relative to the steering seat 13.

[0064] Furthermore, in the embodiment of the present application, the steering seat 13 further includes a second connection portion 133, which is disposed on the body 131 and located on one side of the first connection portion 132. The second connection portion 133 is hinged to the bottom end of the actuator 14 so that the actuator 14 can rotate relative to the steering seat 13.

[0065] Exemplarily, the body 131 is configured as a cylinder, and the second connecting portion 133 is disposed on the outer peripheral wall of the body 131. The second connecting portion 133 is located on the side of the body 131 facing the seat support frame 30. The second connecting portion 133 includes two second mounting ears arranged opposite to each other, and an insertion space is formed between the two second mounting ears. The bottom end of the actuator 14 can be inserted between the two second mounting ears and hinged to the second mounting ears respectively, so that the actuator 14 can rotate relative to the steering seat 13.

[0066] It should be noted that the shapes of the first mounting ear and the second mounting ear can be designed according to the bottom shapes of the riser 12 and the actuator 14. For example, the first mounting ear is a circular mounting ear, and the second mounting ear is a triangular mounting ear, which is not limited in the embodiment of the present application.

[0067] Continue reading Figure 4 The body 131 in the embodiment of the present application is provided with a diameter reducing groove 1311, and the diameter reducing groove 1311 extends along the axial direction of the body 131. Further, fasteners are provided on both sides of the diameter reducing groove 1311 to adjust the gap of the diameter reducing groove 1311 so that the body 131 is fastened to the steering rod.

[0068] For example, the depth of the reducing groove 1311 passes through the side wall of the main body 131, and the reducing groove 1311 extends to the bottom end surface of the main body 131, that is, at least one reducing groove 1311 is provided on the outer peripheral wall of the main body 131, and the contour radius of the main body 131 can be adjusted to facilitate the installation of the steering seat 13 on the steering rod or to be suitable for steering rods of different diameters.

[0069] The actuator 14 in the embodiment of the present application can be one of a gas spring, an electric push rod, and an electric screw, and the actuator 14 has a switch. When the switch of the actuator 14 is turned on, the actuator 14 is in an adjustable state, and the overall length of the actuator 14 can be adjusted; and, when the switch of the actuator 14 is turned off, the actuator 14 is in a locked state, and the overall length of the actuator 14 is not adjustable.

[0070] The following description takes the actuator 14 as an example of a gas spring. The gas spring includes a switch valve, and the gas spring can enter an adjustment state or a locking state by switching the valve. That is, the actuator 14 is configured to be in an adjustable state by switching the valve.

[0071] For example, when the switch valve is in the open state, the gas spring is in an adjustable state, and the inclination angle of the riser 12 can be adjusted; conversely, when the switch valve is closed, the gas spring is in a locked state, and the position of the riser 12 can be locked, that is, after the inclination angle of the riser 12 is adjusted, the switch valve needs to be closed.

[0072] Furthermore, in order to facilitate opening or closing the switch of the actuator 14, the handlebar assembly 10 provided in the embodiment of the present application also includes an adjustment handle 15, which is movably mounted on the seat tube 12 and connected to the switch valve; when the adjustment handle 15 is actuated, the switch can be controlled to be closed or opened.

[0073] For example, the adjustment handle 15 can be a push handle, a pull handle or a rotating handle, that is, the adjustment handle 15 can move up and down along the axis of the vertical pipe 12, or rotate along the circumference thereof, or move along the radial direction thereof, etc., and the embodiments of the present application are not limited to this.

[0074] like Figure 6 and Figure 7 In another embodiment, in order to facilitate the user to turn on or off the switch of the actuator, the handlebar assembly 10 provided in the embodiment of the present application also includes a transmission member 16 connected to the adjustment handle 15, and the adjustment handle 15 can be movably arranged on the handle 11 and linked to the switch through the transmission member 16.

[0075] The transmission member 16 can be a transmission rod or a steel wire rope, one end of the transmission member 16 is connected to the adjustment handle 15, and the other end of the transmission member 16 extends along the vertical pipe 12 and is connected to the switch. When the adjustment handle 15 is actuated, the switch can be acted on by the transmission member 16 to control the closing or opening of the switch. Similarly, the adjustment handle 15 can be a push handle, a pull handle, or a rotating handle, etc., which is not limited in the embodiment of the present application and will not be described in detail here.

[0076] like Figure 5 As shown, the handlebar assembly 10 in the embodiment of the present application is foldable, and the stem 12 of the handlebar assembly 10 can be rotated toward the top of the chassis 20 and fit the chassis 20 as much as possible. Therefore, the side wall of the stem 12 in the embodiment of the present application is provided with an open slot 121, and the open slot 121 is located on the side of the stem 12 facing the actuating member 14. The top end of the open slot 121 extends to the third hinge point, and the bottom end of the open slot 121 extends to the second hinge point. The top end of the actuating member 14 can pass through the open slot 121 to connect to the inside of the stem 12 and form a third connection point, which is located inside the stem 12.

[0077] Such a configuration can avoid interference between the actuator 14 and the seat tube 12 during adjustment of the tilt angle of the seat tube 12, so that the actuator 14 can be at least partially stored in the seat tube 12; that is, the side portion of the actuator 14 facing the seat tube 12 can be bent and completely stored in the opening groove 121, so as to facilitate folding the handlebar assembly 10, so that the seat tube 12 of the handlebar assembly 10 fits with the chassis 20, thereby reducing the storage space of the folded mobility scooter 100.
