[0027] A ready-to-install portable driving assistance device includes a first operating lever, which comprises two or more sections. The two sections are detachably connected via a detachable device. The lowest section is connected to a foot pedal fixing device via a universal joint. The foot pedal fixing device is detachably fixed to the vehicle's foot pedal via a quick-release latch. Figure 1 As shown, in this embodiment, the first operating lever is configured into six segments: the first segment 2, the second segment 3, the third segment 4, the fourth segment 5, the fifth segment 6, and the sixth segment 7. This configuration maintains each segment at approximately 30cm in length, facilitating portability. Each segment can be easily packed into a small bag, significantly improving carrying convenience. For example, when traveling by public transportation, this small bag can be carried, and upon arrival at the destination, the device can be installed in a new car, enabling self-driving in a different location. The detachable mechanism for each segment can utilize threaded connections, sleeve connections, crimp connections, or other common connection structures, allowing for quick assembly and disassembly of each segment.

[0028] Employing a principle similar to the first operating lever described above, a second operating lever is also provided. This second operating lever comprises two or more segments, which are detachably connected via a detachable device. The lowest segment is connected to a foot pedal fixing device via a universal joint, and this foot pedal fixing device is detachably fixed to the vehicle's foot pedal via a quick-release latch. In this embodiment, as... Figure 2 As shown, the second operating lever is configured with 6 segments, namely the first segment 16, the second segment 17, the third segment 18, the fourth segment 19, the fifth segment 20, and the sixth segment 21; the segments can be detachably connected by threaded connection structure, sleeve connection structure, crimp connection structure, or other common connection structures.

[0029] To improve the reliability of the connection, the connection between the segments of the first and second operating levers can be optionally made using a detachable device, such as... Figure 4-7As shown, the detachable device in this embodiment is a composite connection structure. The composite connection structure includes a threaded connector 28 at the top of each rod segment 30; a polygonal male connector 29 is provided below the threaded connector 28; a polygonal female connector 32 is provided at the lower part of the rod corresponding to the polygonal male connector 29, and a lifting threaded connector 35 is provided in the polygonal female connector 32; the lifting threaded connector 35 is provided with a threaded hole 34 corresponding to the threaded connector 28; the exterior of the lifting threaded connector 35 is configured as a polygonal structure corresponding to the polygonal female connector, so that the polygonal lifting threaded connector 35 can only move vertically in the longitudinal direction during use. The above structure has the following effects: the lifting threaded connector 35 is lowered to its lowest position, the threaded connector 28 is threadedly connected to the threaded hole 34, and then the lifting threaded connector 35 and the polygonal male connector 29 move upward together, realizing the insertion of the polygonal male connector 29 and the polygonal female connector 32, preventing relative rotation between the threaded connector 28 and the threaded hole 34, and significantly improving the drawback of loose connection that may occur due to relative rotation between the threaded connector 28 and the threaded hole 34 during daily operation of the operating lever. To facilitate control of the lifting of the lifting threaded connector 35, this embodiment adopts the following scheme:

[0030] like Figure 4 As shown, a partition 31 is also provided above the polygonal plug-in female head 32. In this embodiment, the partition 31 can be a fixed partition, which serves to provide support for the return spring. It also includes a return spring 37, the upper end of which is connected to the partition 31, and the lower end of which is connected to the lifting threaded joint 35. The elastic force of the return spring 37 pulls the lifting threaded joint 35 upward, so that the lifting threaded joint 35 can be in a high position. A push block 33 is provided on the outer side of the lifting threaded joint 35. The side wall of the polygonal plug-in female head 32 is provided with a waist hole 37 corresponding to the push block. The push block 33 passes through the waist hole 37 to the outside. In use, pushing the push block 33 by hand will cause the lifting threaded connector 35 to move downward, thereby connecting the threaded connector 28 to the threaded hole 34. After tightening, releasing the push block 33 will cause the lifting threaded connector 35 to rise back to its original position under the tension of the return spring 37 and with manual assistance, and the polygonal male connector 29 will connect with the polygonal female connector 32. This prevents the threaded connection from loosening during operation. During operation, the main force is the downward push from the hand (i.e., pressing down on the car pedal), and there is generally no upward pull from the hand. Therefore, this structure achieves the required reliability and stability, significantly improving the safety of daily operation. The connection effect of the above structure is as follows: Figure 7 As shown.

[0031] To avoid the situation where the lifting threaded joint 35 cannot be fully pulled up due to fatigue of the return spring 37 after long-term use, or to adjust the tension of the lifting threaded joint 35; and to reduce maintenance costs, in some embodiments, the partition can be configured to be adjustable up and down, thereby adjusting the upward tension of the return spring 37; such as Figure 6 As shown, the lower end of the liftable partition 41 is connected to the upper end of the return spring 37. A threaded hole is provided in the middle of the liftable partition 41, and a rotating rod 39 is provided through the threaded hole. The lower part of the rotating rod 39 is provided with a thread 40, and its upper end protrudes from the top of the threaded connector 28. A notch can be reserved in the middle of the threaded connector 28, and a screw head 38 for rotating the rotating rod 39 is provided in the notch. In order to prevent the rotation of the liftable partition 41, the exterior of the liftable partition 41 can be set as a polygonal structure, and then its lifting inner cavity is also set as a polygonal structure. The effect is as follows: When adjustment is required, the screw head 38 can be rotated with a screwdriver to make the rotating rod 39 rotate. Under the action of the thread 40, similar to the worm gear principle, the liftable partition 41 is made to rise and fall longitudinally, thereby increasing the tension of the return spring 37 on the lifting threaded connector 35. To limit the rotation of the rotating rod 39 and prevent it from over-rotating and causing the liftable partition 41 to come off, a limit head 42 can be provided at the lower end of the rotating rod 39.

[0032] To enable quick assembly and disassembly of this device from the car pedal, in this embodiment, the pedal fixing device adopts the following solution: Figure 1As shown, the foot pedal fixing device of the first operating lever includes an upper pressure plate 9 and a lower pressure plate 12. To improve friction, protrusions 13 or hollow holes can be added to the upper pressure plate 9 and the lower pressure plate 12. Hollow holes can reduce weight. In this embodiment, the universal connector is preferably a spherical universal joint. The ball 8 of the spherical universal joint is connected to the sixth section rod 7, while the upper pressure plate 9 is connected to the base of the spherical universal joint. In some embodiments, it can be integrally formed. The upper pressure plate 9 is provided with quick-release latches on both sides. The lower pressure plate 12 is also provided on the lifting rod 11 of the quick-release latch. The lower pressure plate 12 is located below the upper pressure plate 9. By pressing down the pressure plate 10 of the quick-release latch, the lifting rod 11 is lifted, which in turn drives the lower pressure plate 12 to lift. Finally, the lower pressure plate 9 and the upper pressure plate 12 clamp the car foot pedal. To improve adaptability to car pedals of varying thicknesses, in some embodiments, the lifting rod 11 is threaded, and a fastening nut (not shown) is located at its lower part, below the lower pressure plate 12. The lowest position of the lower pressure plate is adjusted by rotating the fastening nut. During installation, the upper pressure plate 12 and the lower pressure plate 9 are inserted above and below the car pedal respectively, and then the quick-release locking plate 10 is pressed down to achieve a secure connection with the car pedal, making installation convenient.

[0033] The foot pedal fixing device for the second operating lever also adopts a similar structure as described above, such as... Figure 2 As shown, the system includes an upper pressure plate 22 and a lower pressure plate 23. To improve friction, protrusions or perforations can be added to the upper pressure plate 22 and the lower pressure plate 23. In this embodiment, the universal connector is preferably a spherical universal joint. The ball 27 of the spherical universal joint is connected to the sixth rod segment 21, while the upper pressure plate 22 is connected to the base 26 of the spherical universal joint or is manufactured using an integral molding process. The lifting rod 24 is lifted by pressing down its pressure plate 10, which in turn drives the lower pressure plate 23 to lift, and finally clamps the car foot pedal through the lower pressure plate 23 and the upper pressure plate 22.

[0034] Optional, such as Figure 2 As shown, a support plate 14 is provided on the second operating lever, and an insertion hole 15 is provided on the support plate 14; the first operating lever passes through the insertion hole and is supported by the upper part of the first operating lever by the support plate 14.

[0035] Optional, such as Figure 1 As shown, the uppermost section of the first operating lever is detachably connected to a circular pressure head 1; the uppermost segment of the second operating lever is detachably connected to a hand grip. In this embodiment, the first segment 16 is directly made into a hand grip structure. In use, the assembly is as follows: Figure 3As shown, by holding the first lever segment 16 and pressing down on the first lever segment 16, one can control, for example, the accelerator pedal or the brake pedal. By pressing down on the circular pressure head 1, one can control, for example, the brake pedal or the accelerator pedal, making the operation convenient.

[0036] Optionally, for disabled persons, the above-described structure of this device can be used as a cane. In use, the device can be removed from the car, and the bottom section of the first operating lever and / or the second operating lever can be detachably replaced with the cane head (i.e., the bottom of the cane), thus enabling its use as a cane.
