[0039] Embodiment 1 A low - speed electric vehicle wiper gear lever with a gear control switch

[0040] As Figures 1 to 8 shown, in this embodiment, the gear control function and the wiper control function on a low - speed four - wheel electric vehicle are integrated to reduce the occupation of the interior space of the vehicle and facilitate the driver to shift gears flexibly.

[0041] As Figure 1 、 2 shown, this embodiment includes a rod body 1. The rod body 1 is hollow inside to form a cavity 11. One end of the rod body 1 close to the steering wheel (i.e., the left end) is a connection end 12. A knob seat 2 is detachably arranged at the end of the rod body 1 far from the steering wheel. Here, the end of the rod body 1 far from the steering wheel refers to the right end of the rod body 1. The longitudinal section of the knob seat 2 is circular and hollow inside, and a potentiometer 3 is fixedly arranged inside. In this embodiment, the potentiometer 3 adopts a potentiometer 3 with a cylindrical structure in the prior art. Compared with a flat rectangular potentiometer, the cylindrical one has a smaller volume. The structure of the potentiometer 3 will not be described in detail in this embodiment. A gear circuit board 4 is fixedly arranged on the side of the potentiometer 3 facing the rod body 1. The rotating handle 31 of the potentiometer 3 extends out of the knob seat 2, and the extending end of the rotating handle 31 of the potentiometer 3 is fixedly connected to a gear knob 5.

[0042] As Figure 2As shown, the knob base 2 is integrally formed, and successively includes a first split body 21, a second split body 22, and a third split body 23 from right to left. The longitudinal sections of the first split body 21, the second split body 22, and the third split body 23 are all circular. A through hole 211 is formed on the surface of the first split body 21 facing the gear knob 5. The rotating handle 31 of the potentiometer 3 extends out from the through hole 211. The right end of the rotating handle 31 is the extending end, and the extending end is fixedly connected to the gear knob 5. After fixation, the gear knob 5 is sleeved outside the first split body 21.

[0043] The way the potentiometer 3 is fixedly connected to the knob base 2 is as follows: The potentiometer 3 is located inside the knob base 2. The threaded end and the rotating handle 31 of the potentiometer 3 extend out from the through hole 211. A nut is used to pass through the rotating handle 31 from right to left until it reaches the threaded end, and the nut is tightened to fix the potentiometer 3 to the knob base 2. Since the potentiometer 3 adopts the prior art, the Figure 2 threads are not shown in the figure. The rotating handle 31 of the potentiometer 3 is clamped inside the gear knob 5 and fixed by screws. This method is the prior art and will not be elaborated here.

[0044] As shown in Figure 2 and 3 shown, the detachable connection between the rod body 1 and the knob base 2 is realized by a clamping method. Specifically, the outer diameter of the third split body 23 is smaller than the inner diameter of the right end of the rod body 1, and the third split body 23 can be sleeved inside the rod body 1. Along the circumferential direction of one end of the knob base 2 close to the rod body 1 (i.e., the third split body 23), a plurality of first protrusions 231 are arranged at intervals. At the position corresponding to the first protrusions 231 at the right end of the rod body 1, a first clamping groove 14 is provided, and the first protrusions 231 are clamped inside the first clamping groove 14. Specifically, the first protrusions 231 are of a triangular structure. During the process of the third split body 23 being inserted into the rod body 1, the inner wall of the rod body 1 contacts the inclined side 2311 of the first protrusions 231 until the first protrusions 231 completely enter the first clamping groove 14, and then the abutting surface 2312 of the first protrusions 231 abuts against the rod body 1 to achieve fixation. For the fixed state, refer to Figure 1 and 3 and 7. Of course, other detachable connection methods in the prior art can also be adopted between the rod body 1 and the knob base 2. In this embodiment, the number of the first protrusions 231 and the first clamping grooves 14 is four each. Of course, the number can also be set to two, three, or other numbers as long as fixation can be achieved.

[0045] As shown in Figure 1 and 2 shown, a gear position indicating part 7 is arranged on the rod body 1. The gear position indicating part 7 includes a lamp board 701, a lamp board circuit board 702, and an LED lamp 709.

[0046] As shown in Figure 2 and 4As shown in Figures 5 and 6, the lamp board 701 is an arc-shaped sheet structure. The lamp board 701 is detachably arranged on the rod body 1. Specifically, two second protrusions 710 are arranged on the surface of the lamp board 701 facing the rod body 1. Second card slots 15 are arranged on the rod body 1 at positions corresponding to the second protrusions 710. The second protrusions 710 are clamped in the second card slots 15 to fix the lamp board 701 to the rod body 1. This method is the same as the fixing method between the rod body 1 and the knob base 2 described above.

[0047] As Figure 2 , 4 shown, the lamp board circuit board 702 is detachably arranged on the lamp board 701. Specifically, the lamp board circuit board 702 is a rectangular sheet structure, and a first connection hole 703, a second connection hole 704, and a third connection hole 705 are arranged thereon. The first connection hole 703 and the second connection hole 704 are located at diagonal positions on the lamp board circuit board 702. A first support column 706 corresponding to the first connection hole 703, a second support column 707 corresponding to the second connection hole 704, and a third support column 708 that can be inserted into the third connection hole 705 are arranged on the lamp board 701. While the third support column 708 is inserted into the third connection hole 705, two screws are respectively passed through the first connection hole 703 and the first support column 706, and the second connection hole 704 and the second support column 707 to fix the lamp board 701 to the lamp board circuit board 702. After fixing, the lamp board circuit board 702 is located in the cavity 11.

[0048] The LED lamp 709 is fixed on the lamp board circuit board 702 and is electrically connected to the lamp board circuit board 702. As Figure 1 , 2 shown, in this embodiment, an R gear indication position, an N gear indication position, a D gear indication position, and an S gear indication position are arranged on the lamp board 701. LED lamps 709 are arranged at positions corresponding to the R gear indication position, the N gear indication position, the D gear indication position, and the S gear indication position on the lamp board circuit board 702, with a total of four LED lamps 709. The LED lamps 709 and the lamp board circuit board 702 both adopt existing technologies, and their structures and connection principles will not be elaborated here.

[0049] Of course, in this embodiment, only the R gear indication position, the N gear indication position, and the D gear indication position can also be arranged on the lamp board 701 according to actual needs. Refer to Figure 8 .

[0050] In this embodiment, a connecting wire (i.e., a conducting wire) is fixed on the gear position circuit board 4, and the connecting wire is also connected to the lamp board circuit board 702 so that the gear position circuit board 4 and the lamp board circuit board 702 are connected in series. As Figure 5 shown, an outlet hole 13 is arranged at the left end of the rod body 1. One end of the connecting wire far from the gear position circuit board 4 passes through the outlet hole 13, and the passing end of the connecting wire is connected to the tram controller. When in use, rotating the gear position knob 5 to shift gears, when shifting to a certain gear position, the corresponding LED lamp 709 will light up.

[0051] As Figure 2 shown, a number of anti-slip protrusions 51 are provided on the outer contour of the gear shift knob 5, which is convenient for increasing the friction between the hand and the outer contour of the gear shift knob 5.

[0052] Furthermore, as Figure 1 shown, a wiper indication part 6 is provided on the rod body 1. The wiper indication part 6 refers to an indication mark printed on the rod body 1, and this part is the same as the prior art.

[0053] It should be added that in this embodiment, the rod body 1, the knob base 2, the lamp board 701, and the gear shift knob 5 are all made of ABS plastic material.

[0054] In this embodiment, the gear control function and the wiper control function are integrated. Rotating the gear shift knob 5 can realize gear shifting, and moving the rod body 1 forward and backward can start the wiper.

[0055] Embodiment 2 A combined switch

[0056] As Figures 9 - 11 shown, in this embodiment, Embodiment 1 is assembled to the combined switch body 8. Specifically, as Figure 9 shown, this embodiment includes a combined switch body 8 and a vehicle lamp control rod 9 provided on the left side of the combined switch body 8. The combined switch body 8 and the vehicle lamp control rod 9 are both prior art, and their structures and connection relationships will not be elaborated here.

[0057] Embodiment 1 is arranged on the right side of the combined switch body 8. The connecting wire in the cavity of the rod body 1 passes through the wire outlet hole and then enters the combined switch body 8, and finally passes out from below the combined switch body 8 and is connected to the tram controller. The gear shifting function is realized by rotating the gear shift knob 5.

[0058] The connecting end of the rod body 1 is movably connected to the combined switch body 8, and the rod body 1 is connected to the wiper controller on the tram. Here, the movable connection means that when the rod body 1 is moved forward and backward, the wiper can work.

[0059] The connection methods of the rod body 1 to the combined switch body 8 and the rod body 1 to the wiper controller adopt the prior art and will not be elaborated here.

[0060] When in use, this embodiment is installed under the steering wheel. If gear shifting is required, the hand touches the gear shift knob 5 and rotates it. Compared with the prior art where the gear control switch is arranged between the driver's seat and the passenger seat, this embodiment can facilitate the elderly to shift gears flexibly and quickly, and also reduces the occupation of the interior space of the vehicle.

[0061] It should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or perform equivalent replacements on some of the technical features.
