[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 10 The button-mounted knob shown in the figure can rotate 360 ​​degrees and has an anti-theft knob electronic shift mechanism, including a shift bracket 1, on which a knob bracket 2 is provided, the lower part of the shift bracket 1 is a rectangular parallelepiped, and the middle part bulges upward to form a cylindrical hollow connecting part, the knob bracket 2 is a hollow cylindrical shape as a whole, the knob bracket 2 is sleeved on the connecting part, and the knob bracket 2 can rotate smoothly on the connecting part, an upper cover plate 20 is provided above the shift bracket 1, the upper cover plate 20 covers the shift bracket 1 and limits the longitudinal displacement of the knob bracket 2 to prevent the knob bracket 2 from being displaced in the longitudinal direction during the rotation process, and a knob decorative ring 21 is provided above the knob bracket 2, the knob decorative ring 21 is clamped on the knob bracket 2, and the upper cover plate 20 and the upper end of the knob bracket 2 are covered and decorated, a driven gear 3 is provided on one side of the knob bracket 2, and the driven gear 3 is movably mounted on the upper cover plate 20. The edges of the knob bracket 2 and the driven gear 3 form transmission teeth, the knob bracket 2 is meshed with the driven gear 3, a magnet 4 is provided in the driven gear 3, the magnet 4 is fixedly mounted on the lower end surface of the driven gear 3, a sensor is provided below the magnet 4, the sensor is mounted on the circuit board 15 below, the sensor is specifically a 3D Hall sensor, after the knob bracket 2 is turned, the knob bracket 2 drives the driven gear 3 to rotate, the magnet 4 at the lower end of the driven gear 3 rotates above the sensor, the sensor senses the rotation angle of the magnet 4 and then transmits it to the circuit board 15 calculation unit, and then a shift request is issued after calculation.

[0028] The electronic shifter designed in the present invention can realize 360-degree left and right rotation, with 22.5° as a rotation scale. The transmission ratio of the knob bracket 2 and the driven gear 3 is maintained at 1:4. Such a setting can ensure that the rotation angle of each gear position can be divided by 360 degrees, avoiding the superposition of gear positions and having better reliability. The knob bracket 2 can be rotated at any time, and the circuit board 15 calculation unit analyzes whether the gear shifting conditions are met according to the actual situation and chooses whether to execute it. When the knob bracket 2 is rotated to the right by 1 grid, the gear position first enters the N gear state, and then rotates by 1 or any grid to always maintain the D gear state. Conversely, in the D gear state, the knob bracket 2 is rotated to the left by 1 grid, the gear position first enters the N gear state, and then rotates by 1 or any grid to always maintain the R gear state. The above non-fixed gear knob form is adopted, and the gear position is mainly indicated by the state, P->N->D->D or P->N->R->R. The switching between D and R must go through the middle gear N, and requires 2 actions to complete. The gear collection is escorted by the software algorithm to avoid the gear switching problem caused by misoperation. This gear switching form is easy to operate on the one hand, and there is no need to confirm whether the current position is the required gear position, but only the number of rotations. On the other hand, it simplifies the product structure. For example, there is no need to design a gear limit structure and a P gear locking structure, which is lower in cost.

[0029] A positioning tooth-shaped groove 17 is provided at the lower end of the knob bracket 2, and a bullet head 18 is provided on the shift bracket 1. The bullet head 18 contacts the positioning tooth-shaped groove 17. The positioning tooth-shaped grooves 17 are evenly arranged on the outer circle of the lower end of the knob bracket 2. The number of the positioning tooth-shaped grooves 17 is 16. The bullet head 18 is movably arranged on the shift bracket 1 below the positioning tooth-shaped groove 17. The number of the bullet heads 18 is 2, and the two bullet heads 18 are symmetrically arranged. A spring 19 is provided between the bullet head 18 and the shift bracket 1. The spring 19 provides an upward restoring force to the bullet head 18, provides a staggered feeling during the rotation of the knob bracket 2, and improves the shifting feel. After the knob bracket 2 stops rotating, the bullet head 18 is snapped into the positioning tooth-shaped groove 17 for positioning, thereby achieving the purpose of gear positioning.

[0030] The knob bracket 2 is provided with a P-gear button bracket 5, which is movably arranged in the knob bracket 2. The P-gear button bracket 5 is in the shape of a hollow cylinder as a whole. The lower end of the P-gear button bracket 5 extends outward to form a limiting portion. The P-gear button bracket 5 is installed in the knob bracket 2 from the lower end upward. The limiting portion at the lower end of the P-gear button bracket 5 contacts the lower end of the knob bracket 2 to limit the upward displacement stroke of the P-gear button bracket 5.

One silicone button 16 and its corresponding signal receiver form a group, and 3 groups are provided in total. The 3 groups of silicone buttons 16 and signal receivers are evenly distributed at the lower end of the P gear button bracket 5. When it is necessary to engage the P gear, press the P gear button 6 to drive the 3 silicone buttons 16 at the lower end of the P gear button bracket 5 to be pressed down. After the carbon particles contact the signal receiver, the processing unit on the circuit board 15 processes the information and sends out a signal to engage the P gear. When engaging the P gear, 2 of the 3 signal receivers need to be triggered at the same time to be effective, thereby ensuring the reliability of engaging the P gear, and the processing unit of the circuit board 15 needs to perform corresponding diagnosis on the open circuit, short circuit and jamming of the P gear button 6.

At the same time, the signal receiver, P gear signal light and sensor are integrated into a circuit board 15, the number of circuit boards is reduced, and the cost is lower.

[0033] A P-gear anti-theft structure is provided below the knob bracket 2. The P-gear anti-theft structure includes a locking block 7 and a locking hole 8. The locking hole 8 is provided at the lower end of the knob bracket 2. The locking holes 8 at the lower end of the knob bracket 2 are evenly arranged. There are 16 locking holes 8. The locking holes 8 are provided on the inner side of the positioning tooth-shaped groove 17. Each locking hole 8 corresponds to the position of the positioning tooth-shaped groove 17 on its outer side, so that the P gear can be engaged and locked in any gear position. The P gear can be engaged with one key, and the automatic return of the fixed gear mechanism in the off state is cancelled. The locking block 7 is provided below the locking hole 8, and the upper end of the locking block 7 is raised to form a locking head 9, and the locking head 9 is inserted into the locking hole 8 to achieve the purpose of locking the gear position. The locking block 7 is movably connected with the shift bracket 1 through the locking block bushing 23, and the locking block 7 can move up and down in the locking block bushing 23.
