In order to meet the driving needs of more and more people, various OEMs are constantly pursuing the convenience, flexibility, and uniqueness of shifting operations, designing and developing shifting devices of different structural forms, and providing the market with a more novel and special shifting driving experience. For this reason, it is thought of providing a push-pull shifting electronic shifting device to make the shifting sensitive.

[0003] A Chinese patent (publication number: 109114211B) discloses a knob-type electronic shifter with a gear display function, which is provided with a display screen module fixed to a main bracket, and the display screen module is used to directly display the gear information of the vehicle, so that the driver can intuitively see the current gear information of the vehicle on the knob-type electronic shifter, and while the vehicle gear is switched by rotating the knob relative to the main bracket, the display screen module and the main bracket remain relatively fixed, which can ensure that the driver can clearly see the gear information displayed on the display screen module at a fixed viewing angle. In addition, the present invention adopts a main bracket with a support seat, a knob composed of a knob body, a core shaft and a limit bar, and a display screen module fixed on the display screen bracket, and organically connects and combines them, but the knob-type electronic shifter is inconvenient to shift gears, and the shifting is not sensitive enough.

DETAILED DESCRIPTION

[0022] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0023] like Figure 1As shown, a monostable push-pull electronic shift device includes a fixed base plate 1, a shift mechanism 2 is arranged on the fixed base plate 1, the shift mechanism 2 is connected to a gear position sensing mechanism 3 and a first gear shift assembly 4, and the first gear shift assembly 4 is connected to a second gear shift assembly 5. The fixed base plate 1 is the supporting structure of the entire device. The fixed base plate 1 is a flat plate used to install and fix other components. The fixed base plate 1 ensures the stability and structural strength of the entire shift device, so that the components can work in coordination. The shift mechanism 2 is used to change the gear position, and the gear position sensing mechanism 3 is used to sense the gear position information, and can also process and transmit the gear position signal. At the same time, the shift mechanism 2 cooperates with the gear position sensing mechanism 3, the first gear shift assembly 4 and the second gear shift assembly 5 to realize the change of the gear position and transmit the gear position signal.

[0024] The shift mechanism 2 includes a push rod 201 , one end of which is connected to a shift base plate 202 , a roller 203 is disposed on the shift base plate 202 , the roller 203 abuts against the fixed base plate 1 , and one side of the shift base plate 202 is connected to a first shift assembly 4 . The push rod 201 is fixedly connected to the shift base plate 202. The push rod 201 is a hollow structure, and the interior can be used to install a wiring harness to achieve line connection. The shift base plate 202 is a flat plate. Rollers 203 are arranged at the four corners of the shift base plate 202. The roller 203 includes an inner ring and an outer ring. A ball is arranged between the inner ring and the outer ring. The inner ring is fixed, and the outer ring can roll along the fixed base plate 1. The roller 203 allows the shift base plate 202 to move. Grease is applied to the outer ring of the roller 203 and the contact between the upper and lower shells. When shifting gears, the user pushes the push rod 201 by hand, and the push rod 201 drives the shift base plate 202 to move, so that the roller 203 on the shift base plate 202 moves along the fixed base plate 1. When the roller 203 moves, it drives the first shift assembly 4 to move. At the same time, the gear position sensing mechanism 3 can sense the gear position change and complete the gear position change.

[0025] The gear position sensing mechanism 3 includes a circuit board 301, on which a Hall sensor is arranged, and the Hall sensor is a 3D Hall sensor. A roller seat 302 is arranged between the roller 203 and the shift base plate 202, and an induction magnet corresponding to the Hall sensor is arranged in the roller seat 302. The Hall sensor is connected to an integrated controller, and the integrated controller model is SC-GEC024C01. The integrated controller is arranged on the circuit board 301, and a potentiometer 303 is arranged in the push rod 201. The potentiometer 303 can be connected to the circuit board 301 through the wiring harness in the push rod 201. The circuit board 301 integrates electronic components such as the Hall sensor and the integrated controller, and is the core control component of the entire gear position sensing system, which is responsible for processing and transmitting the gear position sensing signal. The circuit board 301 ensures the accurate collection and processing of the gear position signal. The roller seat 302 is used to install the roller 203. At the same time, when the induction magnet arranged in the roller seat 302 moves, the Hall sensor can sense the position of the induction magnet by detecting the change of the magnetic field, thereby determining the gear position of the shift, and ensuring the accuracy and reliability of the shift operation. When the push rod 201 is pushed, the resistance value of the potentiometer 303 outputs a voltage, thereby generating an analog signal of the gear corresponding to the position of the push rod 201. The analog signal is transmitted to the integrated controller on the circuit board 301, and the integrated controller receives the gear change signal. With the coordinated action of the Hall sensor, the induction magnet and the integrated controller, the gear shifting can be made more sensitive.

[0026] like Figure 1 and Figure 3 As shown, the first shift assembly 4 includes a first hollow column 401, which is connected to the shift base plate 202. A first spring 402 is arranged in the first hollow column 401. The first spring 402 is in a compressed state at the beginning. A shift rod 403 is arranged at one end of the first spring 402. A spring groove is opened in the shift rod 403. The first spring 402 is connected in the spring groove. The shift rod 403 is connected to the second shift assembly 5. The first hollow column 401 is used to connect the first spring 402 and the shift rod 403. One end of the first spring 402 and the shift rod 403 can be fixed in the first hollow column 401. The shift rod 403 is a bullet-shaped structure. When changing the gear, the shift rod 403 can be used in conjunction with the second shift assembly 5. The shift rod 403 can slide on the arc plate 504. The arc plate 504 has different gears such as three gears and three positions, three gears and five positions, etc., to provide shifting force and shifting stroke. After the gear shift is completed, the shift rod 403, under the action of the first spring 402, drives the shift rod 403 to automatically reset to the middle position of the gear slot of the arc plate 504. The first spring 402 plays a role of buffering and resetting during the gear shifting process. At the same time, it can automatically reset the shift rod after the gear shift is completed, preparing for the next gear shift.

[0027] like Figure 2As shown, the second shift assembly 5 includes a first support rod 501, which is connected to the fixed base plate 1, and is connected to a first connecting plate 502. The first connecting plate 502 has a first groove 503, and an arc plate 504 is arranged in the first groove 503. The arc plate 504 abuts against the shift rod 403. The first support rod 501 is fixedly connected to the fixed base plate 1 to provide support for the first connecting plate 502 and the arc plate 504. The first groove 503 is used to install the arc plate 504. The arc plate 504 cooperates with the shift rod 403. When shifting, the shift rod 403 slides on the arc plate 504. After the shifting is completed, the shift rod 403 is automatically reset to the middle position of the gear slot of the arc plate 504 under the action of the first spring 402. Under the coordinated cooperation of the shift lever 403 , the arc plate 504 , and the first spring 402 , the shift lever 403 can automatically return to the middle position of the gear slot of the arc plate 504 after the push rod 403 shifts gears.

[0028] like Figure 1 As shown, a limit plate 6 is arranged between the shift bottom plate 202 and the roller 203, and the limit plate 6 abuts against the circuit board 301. The limit plate 6 is a square plate, and the roller 203 moves on the limit plate 6, while the limit plate 6 abuts against the circuit board 301, which is used to limit the position of the circuit board 301, and the circuit board 301 can be limited to a suitable position to prevent excessive movement and damage to components.

[0029] The roller seat 302 includes a first hollow column 401, on which a first limit block 7 is provided, and the roller 203 abuts against the first limit block 7. The roller seat 302 is connected to the shift base plate 202, and is used to connect with the roller 203. The roller seat 302 is a first hollow column 401 structure as a whole, and the hollow structure can save materials and reduce the weight of the roller seat 302 itself. The first limit block 7 is connected to the first hollow column 401, and the roller 203 is sleeved on the first hollow column 401. The first limit blocks 7 are at both ends of the roller 203, and are used to limit the lateral movement of the roller 203.

[0030] like Figure 4 and Figure 5 As shown, the fixed base plate 1 is connected with an upper cover plate 8, and the upper cover plate 8 is provided with a first through slot 9 that matches with the push rod 201. The upper cover plate 8 is connected with the fixed base plate 1 by screws, and the parts on the fixed base plate 1 can be protected. At the same time, the upper cover plate 8 is provided with a first through slot 9, and the push rod 201 can pass through the first through slot 9, which is convenient for users to hold the push rod 201 by hand and use the push rod 201 to shift gears. The first through slot 9 is a square slot, and the push rod 201 can move in the first through slot 9, which is convenient for shifting gears.

[0031] The upper cover plate 8 is connected with a second connecting plate 801, on which a threaded hole 802 is provided, and a reinforcing plate 803 is provided between the second connecting plate 801 and the upper cover plate 8. The second connecting plate 801 is provided at the four corners of the upper cover plate 8, and the second connecting plate 801 is a semicircular structure. The threaded hole 802 on the second connecting plate 801 is used to connect with the vehicle body bolts to fix the entire electronic shifting device on the vehicle body, and at the same time, the reinforcing plate 803 between the upper cover plate 8 and the second connecting plate 801 can strengthen the connection strength between the upper cover plate 8 and the second connecting plate 801.

[0032] The push rod 201 is provided with a dustproof guard plate 204, and the bottom of the fixed base plate 1 is provided with a terminal head 10 corresponding to the circuit board 301. The dustproof guard plate 204 is provided on the push rod 201, and can move forward and backward with the push rod 201, and can prevent dust, impurities, etc. from entering the interior through the gap between the push rod 201 and the upper cover plate 8 to pollute the structure. The terminal head 10 is used to connect the circuit of the circuit board 301.

[0033] Functions and Effects of the Embodiments

[0034] When shifting gears, the push rod 201 is pushed to make the roller 203 on the shifting bottom plate 202 move along the fixed bottom plate 1, and the resistance value of the potentiometer 303 in the push rod 201 outputs a voltage, thereby generating an analog signal of the gear position corresponding to the position of the push rod 201, and the analog signal is transmitted to the integrated controller on the circuit board 301 to receive the gear position change signal. At the same time, when the roller 203 moves, an induction magnet corresponding to the Hall sensor is arranged in the roller seat 302.
