The protrusion 205 is in the shape of a wedge with a tip at the lower end, and can be embedded in the limiting groove 708 , so as to better realize the limiting and ensure that the force arm can accurately drive the corresponding moving member downward.

As shown in FIG. 8 , the housing 100 is provided with a first guide cavity 101 on the first side and a second guide cavity 102 on the second side. The first moving member 701 and the second moving member 801 are respectively movably penetrated through in the first guide cavity 101 and the second guide cavity 102 . The first reset member 702 and the second reset member 802 are respectively the first spring and the second spring sleeved outside the first moving member 701 and the second moving member 801, and the first spring is biased between the first moving member 701 and the second moving member 801.

As shown in FIG. 4 , in one embodiment, when the operating member 300 is in the steady state position in the cavity 204 , the operating member 300 is in the central position at this time, not biased to any side, the first spring and the second spring A slightly compressed and expanded state is used to support the rotating bracket 200 . That is, at this time, the acting forces of the first spring and the second spring on the first force arm 201 and the second force arm 202 respectively are approximately equal to the weight of the rotating bracket 200 . In addition, the first spring and the second spring extend on both sides of the rotating bracket 200 in a symmetrical manner, and the gravity of the rotating bracket 200 is equally shared by the two springs, so the two springs exert equal forces on the rotating bracket 200 .

Since the steady-state position is the most common position of the operating member 300 , the above two springs are slightly compressed and the gravity of the rotating bracket 200 is evenly distributed, so that stress fatigue of one of the springs due to uneven force can be avoided. to ensure the normal reset of the operating member 300.

As shown in FIG. 6 , when the user holds the operating member 300 and pushes it forward, the operating member 300 is in the first working position when the first moving member 701 is pressed down to trigger the first gear contact 401 . At this time, the first force arm 201 pushes down the first moving member 701 , and the second force arm 202 is disengaged from the second moving member 801 . Therefore, the first spring located on the first side is in a compressed state to store energy, while the second spring located on the second side is in a natural expansion state. Then, after the gear shift is completed, the external force exerted by the user on the operating member 300 is removed, the elastic potential energy accumulated by the first spring in the compressed state is released, and the first force arm 201 drives the rotating bracket 200 to swing to the second side until the operating member 300 returns to the steady state position.

Similarly, as shown in FIG. 7 , when the user holds the operating member 300 and pushes it forward, the operating member 300 is in the second working position when the second moving member 801 is pressed down to trigger the second gear contact 402 . At this time, the second lever arm 202 pushes down the second moving member 801 , and the first lever arm 201 is disengaged from the first moving member 701 . Thus, the second spring located on the second side is in a compressed state and stores energy, while the first spring located on the first side is in a natural expansion state. Then, after the gear shift is completed, the external force exerted by the user on the operating member 300 is removed, the elastic potential energy accumulated by the second spring in the compressed state is released, and the second force arm 202 drives the rotating bracket 200 to swing to the first side until the operating member 300 returns to the steady state position.

As shown in FIG. 1 , FIG. 4 to FIG. 7 , in order to protect the gear contacts, the housing 100 is provided with a partition 1000 located above the PCB board 400 , and the partition 1000 is provided with corresponding gear contacts. Cushion pad 1001. In this embodiment, the partition plate 1000 also has the function of waterproof and dustproof, so as to prevent foreign objects from entering the casing 100 and affecting the transmission of the shift signal. Accordingly, the separator 1000 may be made of a flexible material. The buffer pad 1001 is located between the moving piece and the gear contact. When the moving piece moves down, it first contacts and compresses the buffer pad 1001, and the flexible buffer pad 1001 transmits the counteracting force to the corresponding gear contact to realize Trigger action. Thus, protection of the gear contacts can be formed. In addition, due to the flexible and elastic effect of the buffer pad 1001 , after the gear triggering is completed, the buffer pad 1001 can also apply an auxiliary upward reset force to the moving member, so as to promote the normal reset of the operating member 300 .

Further, when the operating member 300 is pushed forward or backward to drive the first moving member 701 or the second moving member 801 to move downward, the first spring or the second spring is compressed, and the buffer pad 1001 is compressed. When compressed, the first moving member 701 or the second moving member 801 will receive an upward reaction force, and the reaction force is transmitted to the operating member 300 through the rotating bracket 200 to form a shift feel.

Therefore, by providing the reset member with a reset function to the rotating bracket 200, on the one hand, the operating member 300 and the rotating bracket 200 can be stably in a stable position without user operation, so as to prevent the operating member 300 and the rotating bracket 200 from accompanying the vehicle Bump and swing back and forth to slow down the wear and tear of the electronic shifter's components. On the other hand, when the operating member 300 deviates from the steady state position, the reset member can exert a reaction force on the operating member 300 through the rotating bracket 200 , so as to feedback the shift feel to the human hand and improve the user experience.

Similarly, the third trigger assembly 900 includes a third moving member 901 disposed between the operating member 300 and the third gear contact 403 , and a third reset member 902 disposed between the third moving member 901 and the housing 100 , the third reset member 902 applies an upward reset force to the third moving member 901 . The housing 100 is provided with a third guide cavity 103 , and the third moving member 901 is movably penetrated in the third guide cavity 103 . The third reset member 902 is a third spring sleeved outside the third moving member 901 , and both ends are biased between the third moving member 901 and the inner wall of the third guide cavity 103 . The structure of the third moving member 901 included in the third trigger assembly 900 is substantially the same as that of the first moving member 701 or the second moving member 801 above. For details, please refer to the above description, which will not be repeated here.

Because the operating member 300 not only needs to drive the rotating bracket 200 to swing back and forth, but also has a degree of freedom to move up and down. Therefore, the second moving member 801 should be movably connected with the operating member 300 . In addition, the movable connection of the two cannot cause the second moving member 801 to be separated from the operating member 300. In view of this, in an optional embodiment, as shown in FIGS. 4 to 7 , the lower end of the operating member 300 is recessed inward to form a groove 302 , and the upper end of the third moving member 901 is embedded in the groove 302 . In addition, the upper end of the third moving member 901 is in clearance fit with the groove 302 .

Specifically, similar to the structure of the first moving member 701 or the second moving member 801, the upper end of the third moving member 901 is also provided with a limiting cap 903. Friction with groove 302. The center of the bottom of the groove 302 is high and the two sides are low, that is, the potential energy of the central portion of the bottom of the groove 302 is greater than that of the edge. The cross-sections of the groove 302 and the limiting cap 903 are circular, and the diameter of the groove 302 is larger than the diameter of the limiting cap 903 , so that the limiting cap 903 and the groove 302 are in clearance fit.

As shown in FIG. 4 and FIG. 5 , when the operating member 300 is in the steady state position, the limiting cap 903 on the upper end of the third moving member 901 is at least partially embedded in the groove 302 , and the side wall of the groove 302 limits the position The cap 903 forms a limiting and righting effect to prevent the limiting cap 903 from moving out of the groove 302 . As shown in FIG. 6 and FIG. 7 , when the operating member 300 is driven to move forward or backward, due to the clearance fit between the limiting cap 903 and the groove 302 , and the edge potential energy of the groove 302 is low, the limiting cap 903 slides Move to the edge position of the groove 302, and be stably clamped at the central part of the bottom of the groove 302 with high potential energy and the inner side wall of the groove 302 for a period of time to avoid the third moving member 901 when the operating member 300 is in an unsteady position. Risk of detachment from operating member 300 .

The working principle of the electronic shifter of the embodiment of the present application is as follows:

After the P gear button 600 is pressed, the gear position is initially in the P gear (the P gear indicator light is on). At this time, the user moves the operating member 300 forward or backward to release the P gear (the P gear indicator is off), and the gear shifts to the N gear (the N gear indicator is on). Then, when the user pushes the operating member 300 forward, the gear shift enters the R gear (the R gear indicator light is on). When the user pushes the operating member 300 backwards, the gear shift enters the D gear (the D gear indicator light is on). When the gear is in the D gear, press the operating member 300 to enter the M gear, and switch to the manual mode (the M gear indicator light is on). Then, the operating member 300 is toggled forward or backward to perform an upshift (M+) or downshift (M-) operation. Press down the operating member 300 again to return to the automatic mode (the indicator light for the D position is on, and the indicator for the M position is off).

The above are only a few embodiments of the present application, and those skilled in the art can make various changes or modifications to the embodiments of the present application without departing from the spirit and scope of the present application according to the contents disclosed in the application documents.
