[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following description, in conjunction with the accompanying drawings, describes an embodiment of the driver assistance device for disabled persons.

[0021] like Figure 1-3As shown, the vehicle driving assistance device for people with limb disabilities includes a mounting base 1, a connecting rod 2, a handle 3, a throttle control mechanism, and a brake control mechanism.

[0022] The connecting rod 2 is mounted on the mounting base 1, which can be fixed in a suitable position in the car's cab by bolts or other connecting parts. A side plate 4 is mounted on the side of the connecting rod 2. The upper end of the side plate 4 has a semi-circular structure, and an arc-shaped limiting plate 5 is provided on the upper part of the side plate 4, forming an arc-shaped groove 6 between the arc-shaped limiting plate 5 and the upper part of the side plate 4.

[0023] One end of the handle 3 is rotatably mounted on one side of the side plate 4 via a pivot, facilitating the rotation of the handle 3. A connecting rod 7 is rotatably mounted on the other side of the side plate 4. One end of the connecting rod 7 is a hook-shaped limiting mechanism 8 located on one side of the arc-shaped groove 6, and the end of the connecting rod 7 away from the hook-shaped limiting mechanism 8 is hinged to the throttle control mechanism.

[0024] The throttle control mechanism includes a throttle connecting rod 10. One end of the throttle connecting rod 10 is hinged to the connecting rod 7, and the other end is hinged to a throttle fixing structure 11. The throttle fixing structure 11 can be connected to the car's accelerator pedal. When the connecting rod 7 rotates, the throttle connecting rod 10 drives the throttle fixing structure 11 to move, thereby realizing the control of the throttle.

[0025] The brake control mechanism is hinged to the middle of the handle 3. The brake control mechanism includes a brake connecting rod 12 hinged to the handle 3. The brake connecting rod 12 is a telescopic rod, and a brake fixing structure 13 is provided at the end furthest from the handle 3. The brake fixing structure 13 can be connected to the vehicle's brake pedal. Because the brake connecting rod 12 is a telescopic rod, its length can be adjusted according to actual needs to adapt to different vehicle models. When the handle 3 is rotated, the brake connecting rod 12 drives the brake fixing structure 13 to move, thereby achieving brake control.

[0026] A limiting post mechanism for the hook-shaped limiting mechanism 8 is installed on the side of the handle 3. The limiting post mechanism includes a stud 14, which extends through the handle 3 into the inner side of the hook-shaped limiting mechanism 8. A limiting nut 15 is provided on the stud 14 near the column of the hook-shaped limiting mechanism 8. A limiting spring 16 is provided between the stud 14, the limiting nut 15, and the handle 3. During the rotation of the handle 3, the limiting post mechanism and the hook-shaped limiting mechanism 8 cooperate with each other to perform the functions of limiting and transmitting power.

[0027] The upper part of the arc-shaped limiting plate 5 is provided with limiting teeth 9, and the handle 3 is equipped with a locking mechanism that cooperates with the limiting teeth 9 for limiting. The locking mechanism includes a locking pin 17 and two upper limiting blocks 18 and lower limiting blocks 19 with holes, which are set on the side of the handle 3 and arranged vertically. The locking pin 17 is set through the holes of the upper limiting block 18 and the lower limiting block 19. A limiting plate 20 is provided on the upper part of the locking pin 17 and the upper part of the lower limiting block 19. A restoring spring 21 is sleeved on the locking pin 17, and the two ends of the restoring spring 21 abut against the upper limiting block 18 and the limiting plate 20, respectively. When the handle 3 is rotated to a certain position, the locking pin 17 is locked into the limiting teeth 9 under the action of the restoring spring 21, thereby limiting the handle 3 and preventing the handle 3 from rotating on its own when not in operation.

[0028] The working principle of this utility model is as follows: In use, the mounting base 1 is fixed in the car's driver's cab. The accelerator fixing structure 11 is connected to the car's accelerator pedal, and the brake fixing structure 13 is connected to the car's brake pedal. At this time, both the accelerator and brake are in their initial unpressed state, and the brake connecting rod 12 is not extended. When the accelerator needs to be controlled, the handle 3 is turned (backward). The rotation of the handle 3 drives the limiting post mechanism to rotate synchronously, thereby abutting the hook-shaped limiting mechanism 8, causing the connecting rod 7 to rotate. The connecting rod 7, through the accelerator connecting rod 10, drives the accelerator fixing structure 11 to move, thereby controlling the accelerator size. Simultaneously, the locking post 17 in the locking post mechanism can engage with the limiting tooth 9 to achieve uniform forward movement. When braking is needed, the handle 3 is turned (forward). The handle 3, through the brake connecting rod 12, drives the brake fixing structure 13 to move, achieving braking. During operation, the locking post mechanism and the limiting tooth 9 cooperate to limit the handle 3, ensuring the stability and safety of operation.
