Description

Shifting car and its carrier

The present invention relates to a shifting vehicle, and more particularly to a driving vehicle comprising two driving main wheels that can respectively control the rotational speed.

The medium-wheel drive displacement device has a small radius of gyration and is suitable for use in wheelchairs that require movement in a narrow space such as indoors. The pair of intermediate wheels of such a displacement device are usually driven by different drive motors, respectively, and can be steered or simply advanced and retracted by controlling the center wheels to rotate at different speeds or the same speed.

For example, "Mid-wheel drive power wheelchair" in U.S. Patent No. 5,944,131, "Chassis structure for mid-wheel drive power wheelchair" in U.S. Patent No. 7,828,310, and "Suspension system for a" in U.S. Patent No. 6,070,098 Wheelchair, etc.

These mid-wheel-driven displacement devices usually match the front and rear auxiliary wheels to increase the stability of the movement to avoid tipping. However, in some cases, these auxiliary wheels may excessively increase the load of the driving wheel (middle wheel), and may easily cause overload of the driving motor. For example, when the position of the front auxiliary wheel is relatively high and the user controls the driving wheel to perform steering, it is difficult to smoothly move because the front auxiliary wheel and the rear auxiliary wheel fail to land in a better manner. Therefore, when the drive wheels are steered in this case, the front and rear auxiliary wheels are instead obstructed and the load of the drive wheels is increased.

Therefore, in order to improve the practicability of the displacement device, the present inventors have proposed a carrier for a driving carrier, the driving carrier comprising two driving main wheels that can respectively control the rotational speed, the carrier comprising: a first body and a second body. The first base body is configured to connect to the drive carrier, and the first base body includes at least one first mounting portion. The second seat body comprises a plurality of wheel carriers and one of the mounting frames of the wheel carrier, each wheel frame is provided with an auxiliary wheel, and the installation frame defines an active space between the mounting frame and the wheel carrier. The driving carrier is located at the activity. The mounting bracket includes at least one second mounting portion, and one of the first mounting portion and the second mounting portion is a rod body, and the other of the first mounting portion and the second mounting portion has a through portion. The rod body is movably disposed in the through portion, so that when the second seat body is displaced relative to the first seat body, the auxiliary wheels are all movably displaced relative to the driving main wheel of the driving carrier.

Further, the first base body includes two first side bars and two first connecting rods opposite to each other, and each of the first side bars has the first mounting portion, and the first connecting rods are opposite to each other and are connected to the first side. a second mounting bar and two second connecting rods, wherein each of the second side bars has a second mounting portion, and the second connecting rods are opposite to each other and connected to the second side bar .

Further, the rod body and the penetrating portion are substantially perpendicular to a horizontal plane, and a sliding member is disposed between the rod body and the wearing portion. The sliding aid is for example a linear bearing.

Further, the utility model further comprises a stepping rod connected to the second seat body.

Further, the rod body has a limiting portion to limit the distance between the first seat body and the second seat body relative to each other.

Further, an elastic member is further included, and the elastic member is respectively connected to the first seat body and the second seat body to serve as a buffer when the second seat body is displaced relative to the first seat body.

Further, the elastic member is a spring and is sleeved on the rod body.

Further, the first seat body is movably connected to the driving carrier, and the second seat body has two abutting bars, wherein the abutting bars respectively correspond to the driving main wheels of the driving device, so that the driving carrier is opposite to the first When the seat is displaced, the abutting rod is brought against the driving main wheel.
