Description

Improvement of Vehicle Shifting Mechanism

The present invention provides an improvement of a vehicle shifting mechanism, especially an improved design of a vehicle shifting mechanism in a fully automatic shifting mode through a control switch and an automatic shifting switch cooperating with a shifting drive unit to control the action of pressing down to enter a gear or pushing up to reverse a shift.

Press, as we all know, due to the gearbox, the shift car can change gears when it needs a lot of power for starting or when it needs different road conditions such as climbing, so as to meet the required power, and then can greatly save energy. Purpose, but if the driver wears high-grade and expensive shoes, when the instep hooks the shift lever 61, the surface of the shoes will be scratched and damaged by the shift lever 61, and if wearing thick shoes or rain boots, shoe covers, etc. during rainy days, it will also affect the normal operation when hooking the shift lever 61 and returning to the previous gear.

Moreover, the general gear car needs to use the foot to shift the gear lever 61 into and out of gear. In addition to the people who are familiar with the shifting car, there are still many people who are not familiar with the gear shifting of the gear car and cannot drive the gear car.

＜Technical problems to be solved＞ In view of the above-mentioned practical difficulties and deficiencies to be improved in the conventional vehicle gear shifting design, the inventor hopes to provide a breakthrough design to enhance the practical effect. He has devoted himself to research, design and assembly, integrated his professional technical knowledge and practical experience in the design, production and sales of related products for many years, as well as the results of research and design, and finally researched the improvement of a vehicle gear shifting mechanism of the present invention to provide users.

＜Technical means to solve problems＞ The present invention provides an improvement of a vehicle shifting mechanism, which includes a gearbox, a shifting drive unit and a shift lever. The shift lever is set on the shift shaft of the gearbox. The shift drive unit is arranged on one side of the shift lever. The operation of controlling the shifting or shifting is carried out through the electrical connection between the control switch located next to the vehicle handle and the shift drive unit, and then the shift drive unit drives the shift lever to produce the action of pressing down for shifting or pushing up for shifting. Control the main processor. When the automatic shift switch is turned on and the automatic shift mode is activated, the driving control main processor will receive the data of the main power motor or engine speed and torque load to activate the shift drive unit at the optimal time point to drive the shift lever to produce fully automatic control of down-pressing the shift lever or pushing up the shift lever and neutral gear.

The shifting drive unit includes a motor, a reducer and a cam. The motor group is arranged at the input end of the reducer. The first reduction gear and the second reduction gear are installed in the housing of the reducer. The second reduction gear has a power output shaft extending out of one side of the housing. A circuit board with a micro-motion sensing element is arranged on the side of the housing. The second reduction gear and the circuit board are sealed in the housing by a side cover and a gasket. A cam is provided on the power output shaft of the second reduction gear. The cam on the power output shaft of the second reduction gear rotates forward or reverse, and the magnetic element or convex part on the second reduction gear generates sensing or pressure contact with the micro-motion sensing element, and then stops the motor after the cam rotates forward or reverse 360 degrees to stop the cam at its original position.

The shifting drive unit is locked and assembled on the side cover of the gearbox for easy maintenance or replacement of the shifting drive unit.

The micro-motion sensing element can be a sensing chip or a micro-switch, and an outer cover is provided outside the side cover of the gearbox, which has the effect of being beautiful and antifouling.

＜Efficacy compared with previous technology＞ The main purpose of the present invention is to use the control switch and the automatic shift switch to control the shifting drive unit to perform the operation of shifting gears, shifting gears, and automatic shifting. With the algorithm built in the main processor of the driving control, according to the actual load conditions of the vehicle during driving, it can be switched to the most appropriate gear at the best shifting time to achieve the purpose of saving energy and increasing the endurance of the vehicle. There is no need to change gears by stepping on or unhooking the shift lever, thereby improving driving safety.

The second purpose of the present invention is mainly the design of the present invention, except the people who are generally familiar with the shifting car, also allows the people who cannot drive the shifting car to drive the shifting car easily, and can also experience the fun of shifting the shifting car.

Another object of the present invention is to use the control switch and the automatic shifting switch to control the shifting drive unit. In addition to the traditional foot control shifting, the control switch set at the appropriate position on the handle can be used to manually shift or switch to automatic shifting. The shifting drive unit enables the shifting car to have the ability to control the shifting with the foot or use the control switch and the automatic shifting switch to control the shifting drive unit to perform the control of shifting, shifting, and automatic shifting, thereby improving the driving experience and economic value of the shifting car.
