Description

Technical Field

[0001] The present invention belongs to the technical field of new energy vehicles, and particularly relates to a gear shifting operating device and its application. Background Art

[0002] New energy vehicles (NEVs) utilize non-traditional fuels as their power source (or traditional fuels but with new power units), integrating advanced technologies in vehicle power control and drive. These vehicles feature advanced technical principles, new technologies, and new structures. With the rapid development of NEVs, the reliability and service life of the gearshift mechanism, a core component of the vehicle control system, directly impact driving safety and user experience. Currently, most gearshift mechanisms utilize mechanical contact solutions (such as push rods and knobs). These solutions rely on physical contact to trigger circuit signals. Long-term use can lead to contact wear and elastic element fatigue, resulting in shift failures, vehicle inability to start, and other faults.

[0003] There are studies in the prior art on the problems of the current mechanical contact-type shifting devices, such as patent CN107524795A - a pure electric vehicle shift control device assembly and shift control method, which realizes electronic shift control by sensing the position of the shift lever through Hall elements. Although it avoids mechanical wear, the single sensing mechanism is prone to misjudgment when there is strong electromagnetic interference or magnet demagnetization, and lacks redundant backup; patent CN108426031A - a single-control interlocking electric vehicle transmission shift mechanism and transmission, which adopts multiple actuators to collaboratively control gear switching, with stringent control accuracy requirements, increasing the complexity and failure risk of the system, and seriously affecting the smoothness of operation; patent CN102588527A - an electric vehicle automatic transmission, which adopts a multi-plate clutch + synchronizer + planetary gear set, resulting in bloated axial space, making it difficult to adapt to the compact layout of new energy vehicles, and the shift control mainly relies on the interaction of mechanical components, lacking the precision and flexibility of electronic control.

Therefore, a new technical solution is needed to address these technical issues. Summary of the Invention

[0012] Compared with the prior art, the present application has the following advantages: 1. The present application adopts electromagnetic induction and mechanical contact dual mechanism to cooperatively collect gear shifting signals, overcomes the defect that single electromagnetic induction mechanism is prone to misjudgment in strong electromagnetic interference or magnet demagnetization, ensures the accuracy and reliability of gear shifting operation, greatly improves the safety of vehicle driving, integrates the two signal collection methods of electromagnetic induction and mechanical contact, discards the traditional independent arrangement mode of mechanical contact and electromagnetic inductor, on the basis of which, the lower part of the gear shifting lever is provided with four radially extending stop blocks, each stop block is fixed with a magnet on the side wall and magnetically cooperates with a corresponding electromagnetic inductor on the circuit control plate, at the same time, an elastic contact block is arranged below the movement path of the corresponding stop block on the circuit control plate, fully utilizes the internal space of the shell, makes the whole device structure more compact, effectively improves the space utilization, better adapts to the compact layout requirement of new energy vehicles, solves the problem of large space occupation caused by independent arrangement of components in the prior art, accurately controls the gear shifting stroke of the gear shifting lever through the cooperation of the limiting rod and the limiting block, ensures that the gear shifting lever can accurately reach each gear position, avoids the problems of gear shifting out of position or over shifting, the precise limiting design improves the accuracy and reliability of gear shifting, enables the driver to more easily and accurately complete the gear shifting operation, and provides the driver with a smoother and more accurate gear shifting experience. 2. By arranging the four shift blocks (forward, stop, low-speed climbing, and reverse) in a cross-shaped configuration around the cross-section of the shift lever, the present invention enables the driver to quickly and intuitively find the desired gear without complicated thinking or groping. This greatly improves the convenience and efficiency of shifting and reduces the safety hazards caused by misoperation of the gear. It also fully utilizes the three-dimensional space around the shift lever, making the entire shift operating device more compact. 3. The present invention adopts an electromagnetic sensor whose induction part passes through the sensor bracket and is bent to the left side and arranged opposite to the magnet, so that the induction part can be closer to the magnet, thereby enhancing the sensitivity and accuracy of magnetic field sensing. Compared with the traditional electromagnetic sensor arrangement, it can more accurately capture the magnetic field changes of the magnet on the gear block, thereby more accurately judging the position of the gear shift lever and improving the reliability of gear shift signal acquisition. The sensor bracket and the circuit control board are arranged with spacing support, which provides a stable support structure for the electromagnetic sensor, so that the impact of vibration and impact on the electromagnetic sensor during driving of the vehicle can be effectively reduced, ensuring its normal operation, thereby extending the service life of the electromagnetic sensor. On this basis, the ear seat is used to support and connect the bent part of the electromagnetic sensor, further enhancing the structural stability of the electromagnetic sensor, so that the electromagnetic sensor can effectively prevent deformation or displacement caused by external force when the gear shift operation is affected by the support of the ear seat, ensuring its accurate relative position with the magnet, thereby ensuring the stability of signal acquisition, and also making the installation and disassembly of the electromagnetic sensor more convenient, effectively reducing maintenance cost and time; 4. The present invention employs a limit sleeve mounted on the outer portion of the upper end of the elastic contact block to limit the lateral movement of the elastic contact block, preventing it from deflecting or deforming during contact with the stop block contact. This protects the structural integrity of the elastic contact block and extends its service life. The limit sleeve's limiting effect ensures accurate contact between the elastic contact block and the stop block contact, evenly distributes contact pressure, and improves contact reliability. This effectively avoids poor contact caused by deflection of the elastic contact block and ensures stable transmission of mechanical contact signals. 5. The present invention achieves multi-level precise positioning of the shift lever by means of a limiting ball on the upper portion of the limiting lever that moves within the cavity formed between the upper and lower bowl-shaped bushings and cooperates with the shift slots on the upper guide plate. This ensures that the shift lever is accurately positioned when switching between gears, effectively improving the smoothness of shifting, avoiding incomplete or overshifting, and enhancing the accuracy and reliability of shifting. Furthermore, a limiting spring disposed between the upper end of the sliding ball and the bottom end of the circuit control board provides a buffering and shock-absorbing effect during the shifting operation, thereby protecting the structural stability of the entire shift operating device. 6. The present invention effectively blocks dust and debris from entering the interior of the housing through an elastic dust cover covering the top of the housing, thereby protecting key components such as the internal circuit control board, electromagnetic sensor, elastic contact block, etc. from contamination and damage, extending the service life of these components, reducing the occurrence rate of failures, improving the reliability of the entire device, and ensuring the smooth operation of the shift lever; on this basis, by setting indicator lights on the elastic dust cover corresponding to the position of each gear block, the driver can intuitively display the current gear status during the gear shift operation, helping the driver to make operational decisions quickly and accurately, thereby improving driving safety and user experience.

The upper and lower surfaces of the limit ball 11 are respectively fitted with an upper bowl-shaped bushing 12 and a lower bowl-shaped bushing 13 (the upper bowl-shaped bushing and the lower bowl-shaped bushing are made of pom material). The outer surface of the upper bowl-shaped bushing 12 is covered with an upper guide plate 14 fixed to the upper part of the sensor bracket 6. A gear groove 1401 matching the corresponding gear block is opened on the upper circumference of the upper guide plate 14. At the same time, the upper bowl A shift groove 1401 matching the corresponding shift block is also provided on the upper circumference of the upper bowl-shaped bushing 12 and the lower circumference of the upper bowl-shaped bushing 12.

[0021] The working principle and use process of the present invention: Figures 1-10 As shown in the figure, after the gear shift operating device is assembled, the device is applied as a whole to new energy vehicles (the functions and structures of conventional equipment such as new energy vehicles are well known in the art, and the connection settings are also common knowledge, so they are not explained here and are not shown in the accompanying drawings), and is installed in the cab of the new energy vehicle. The purpose is to overcome the defect that a single electromagnetic induction mechanism is prone to misjudgment when there is strong electromagnetic interference or demagnetization of the magnet, ensure the accuracy and reliability of the gear shift operation, greatly improve the safety of vehicle driving, and make full use of the internal space of the shell to make the entire device structure more compact, effectively improve space utilization, and better adapt to the compact layout requirements of new energy vehicles. It solves the problem of large space occupation due to the independent arrangement of components in the existing technology. At the same time, it can enable the driver to complete the gear shift operation more easily and accurately, providing the driver with a smoother and more precise gear shifting experience.

[0022] When the driver operates the forward gear while the vehicle is driving, he needs to first hold the shift lever 3 with his operating hand, and then push the shift lever 3 forward, so that the limit rod 305 moves backward with the limit ball 11 as the center by using the lever principle, so that the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove on the rear side of the limit block 101. At this time, the contact 9 at the end of the forward stop block 301 on the front side of the shift lever 3 will contact the corresponding elastic contact block 8, so that the corresponding elastic contact block 8 moves downward and abuts against the pressure rod 801. At the same time, the magnet 4 on the side wall of the forward stop block 301 will face the corresponding electromagnetic sensor 5 while abutting against the contact 9 downward, and generate magnetic interlocking. At this time, the circuit control board 2 detects the forward gear signal under the dual action of the corresponding elastic contact block 8 abutting the pressure rod 801 downward and the corresponding electromagnetic sensor 5 magnetic interlocking, and transmits it to the integrated circuit interface 20, forcing the vehicle to enter the forward state; When it is necessary to shift from the forward gear to the stop gear, the driver first holds the shift lever 3 and moves it backward to the neutral position, so that the limit rod 305 uses the lever principle to move forward with the limit ball 11 as the center. When the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove in the middle of the limit block 101, the contact 9 at the end of the forward block 301 will disengage from the corresponding elastic contact block 8, and the elastic contact block 8 will bounce up when the contact 9 leaves, and the circuit signal will be disconnected. At the same time, the magnet 4 on the forward block 301 will also be misaligned with the corresponding electromagnetic sensor 5 as the contact 9 leaves, thereby releasing the magnetic interlock, and then the shift lever 3 is moved backward again, so that the limit rod 305 uses the lever principle to continue to move forward with the limit ball 11 as the center. The shift lever 305 is moved so that the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove on the front side of the limit block 101. At this time, the contact 9 at the end of the stop block 302 on the rear side of the shift lever 3 will contact the corresponding elastic contact block 8, causing the corresponding elastic contact block 8 to move downward and abut against the pressure rod 801. At the same time, the magnet 4 on the side wall of the stop block 302 will be opposite to the corresponding electromagnetic sensor 5 while the contact 9 abuts downward and generate magnetic interlocking. At this time, the circuit control board 2 detects the stop gear signal under the dual action of the corresponding elastic contact block 8 abutting the pressure rod 801 downward and the corresponding electromagnetic sensor 5 magnetic interlocking, and transmits it to the integrated circuit interface 20, forcing the vehicle to enter a stopped state, that is, completing the gear shift; When it is necessary to shift from the stop gear to the low-speed climbing gear, the driver first holds the shift lever 3 and moves it forward to the neutral gear, so that the limit rod 305 uses the lever principle to move backward with the limit ball 11 as the center. When the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove in the middle of the limit block 101, the contact 9 at the end of the stop block 302 will disengage from the corresponding elastic contact block 8, and the elastic contact block 8 will bounce up when the contact 9 leaves, and the circuit signal will be disconnected. At the same time, the magnet 4 on the stop block 302 will also be misaligned with the corresponding electromagnetic sensor 5 as the contact 9 leaves, thereby releasing the magnetic interlock, and then the shift lever 3 is moved to the left again, so that the limit rod 305 uses the lever principle to move to the right with the limit ball 11 as the center. The shift lever 305 is moved so that the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove on the right side of the limit block 101. At this time, the contact 9 at the end of the low-speed climbing block 303 on the left side of the shift lever 3 will contact the corresponding elastic contact block 8, causing the corresponding elastic contact block 8 to move downward and abut against the pressure rod 801. At the same time, the magnet 4 on the side wall of the low-speed climbing block 303 will be opposite to the corresponding electromagnetic sensor 5 while the contact 9 abuts downward and generate magnetic interlocking. At this time, the circuit control board 2 detects the signal of the low-speed climbing gear under the dual action of the corresponding elastic contact block 8 abutting the pressure rod 801 downward and the corresponding electromagnetic sensor 5 magnetic interlocking, and transmits it to the integrated circuit interface 20, forcing the vehicle to enter the low-speed climbing state. When it is necessary to shift from the low-speed climbing gear to the reverse gear, the driver first holds the shift lever 3 and moves it to the right to the neutral gear, so that the limit rod 305 uses the lever principle to move to the left with the limit ball 11 as the center. When the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove in the middle of the limit block 101, the contact 9 at the end of the low-speed climbing block 303 will disengage from the corresponding elastic contact block 8, and the elastic contact block 8 will bounce up when the contact 9 leaves, and the circuit signal will be disconnected. At the same time, the magnet 4 on the low-speed climbing block 303 will also be misaligned with the corresponding electromagnetic sensor 5 as the contact 9 leaves, thereby releasing the magnetic interlock, and then the shift lever 3 is moved to the right again, so that the limit rod 305 uses the lever principle to move with the limit ball 11 The center continues to move leftward, so that the sliding ball 16 at the bottom end of the limit rod 305 slides into the sliding groove on the left side of the limit block 101. At this time, the contact 9 at the end of the reverse block 304 on the right side of the shift lever 3 will contact the corresponding elastic contact block 8, causing the corresponding elastic contact block 8 to move downward and abut against the pressure rod 801. At the same time, the magnet 4 on the side wall of the reverse block 304 will face the corresponding electromagnetic sensor 5 while the contact 9 abuts downward, and generate a magnetic interlock. At this time, the circuit control board 2 detects the stop gear signal under the dual action of the corresponding elastic contact block 8 abutting the pressure rod 801 downward and the corresponding electromagnetic sensor 5 magnetic interlocking, and transmits it to the integrated circuit interface 20, forcing the vehicle to enter the reverse state; When the vehicle needs to enter the mountain mode, the driver only needs to hold the shift lever 3 and shift it to neutral. At this time, the sliding ball 16 at the bottom end of the limit rod 305 stays in the sliding groove in the middle of the limit block 101. The circuit control board 2 will not receive the signal of the elastic contact block 8 abutting the pressure rod 801 and the magnetic interlocking of the electromagnetic sensor 5, so that the vehicle starts to drive in the road adaptive mode, that is, the vehicle is in the mountain mode.

[0023] When the driver needs to perform any gear shifting operation, the above operation process can be followed by analogy. During the gear shifting process, the driver can intuitively observe the gear shifting status through the corresponding indicator light 19, and can also intuitively determine the gear fault by observing the corresponding indicator light 19.
