[0010] Preferably, the encoding magnet is a tile structure, the first encoding part, the second encoding part, the third encoding part and the fourth encoding part are arranged along the arc direction of the encoding magnet in sequence.

[0011] Preferably, when the hollow knob rotates from the starting point of the stroke to the ending point of the stroke, the first encoding part, the second encoding part, the third encoding part and the fourth encoding part are driven by the encoding magnet to pass through the induction area of the magnetic induction assembly in sequence.

[0012] Preferably, the hollow knob can also move relative to the base, the first circuit board is further provided with a third Hall element, the hollow knob is provided with a first magnetic element, the first magnetic element is offset from the third Hall element in normal state, and when the hollow knob is pressed to move, the first magnetic element moves to the induction area of the third Hall element.

[0016] Compared with the prior art, the present application has the following beneficial effects:

[0017] 1. The coding magnet achieves the coding effect through the arrangement and combination of multiple polarities. The magnetic induction component causes the first circuit board to output the corresponding control signal according to the corresponding code. Moreover, the shifting mechanism has a compact structure and can switch a large number of gears.

[0018] 2. The number of encoders is equal to the number of rotations of the hollow knob. When switching gears, each rotation of the hollow knob switches one encoder, which moves the next encoder to the sensing area of ​​the magnetic induction component.

[0019] 3. The encoding section consists of two magnetic regions, and the magnetic induction component consists of two Hall elements. The first Hall element is used to correspond to and sense the first magnetic region, and the second Hall element is used to correspond to and sense the second magnetic region. Since the polarity of the magnetic region can be either S pole or N pole, the four encoding sections can form a total polarity arrangement of S pole-S pole, N pole-N pole, S pole-N pole, and N pole-S pole.

[0020] 4. When the hollow knob is pushed, it can move along the axial direction of the base, bringing the first magnetic element closer to the third Hall element, thereby causing the first circuit board to output a corresponding signal.

[0021] 5. The bracket is inside the hollow knob and can be slidably connected to the base. The bracket cannot rotate relative to the base. The hollow knob has a contact block inside that holds the bracket against the base so that the bracket and the hollow knob can move together. When the bracket moves, it can drive the first magnetic element to move, thereby changing the position of the first magnetic element. The third Hall element outputs a signal according to the position of the first magnetic element (i.e., when the first magnetic element moves to the sensing area of ​​the third Hall element).

Detailed Implementation

[0031] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings to further illustrate the technical solutions of the present invention. However, the present invention is not limited to these embodiments.

[0032] like Figures 1-6 As shown, a shifting mechanism based on an coded magnet includes: a joystick assembly, which includes a base 100, a first circuit board 200, and an coded magnet 300. The first circuit board 200 is fixedly connected to the base 100, and a magnetic induction component 210 is disposed on the first circuit board 200. The magnetic induction component 210 is composed of at least two Hall elements. The coded magnet 300 can rotate around the circumference of the base 100. The coded magnet 300 includes at least two coded sections arranged sequentially along the rotation direction of the coded magnet 300. Each coded section is composed of at least two magnetic regions. By rotating the coded magnet 300, any coded section can be moved to the sensing area of ​​the magnetic induction component 210. When the coded section is located in the sensing area of ​​the magnetic induction component 210, each Hall element of the magnetic induction component 210 senses each magnetic region of the coded section in a one-to-one correspondence, and the magnetic induction component 210 outputs a corresponding signal according to the polarity arrangement of each magnetic region of the coded section.

[0033] The base 100 is mainly used to carry the first circuit board 200, and the encoding magnet 300 has at least two rows of encoding parts, the polarities of the encoding parts are different, that is, the polarities of each encoding part are unique, and the magnetic induction assembly 210 can identify the magnetic field of each encoding part according to the Hall induction principle, thereby outputting a corresponding voltage signal; the encoding principle of the encoding part is to set at least two magnetic regions, the polarities of the magnetic regions are S or N, so that the at least two magnetic regions can form at least four polarities, and each Hall element of the magnetic induction assembly 210 corresponds to each magnetic region of the encoding part, so that the corresponding voltage signal can be output according to the polarity arrangement of each encoding part.

[0034] It should be pointed out here that at least two magnetic regions are set because a single magnetic region can only form two polarities, resulting in a small number of gear positions that can be formed, and the more magnetic regions of the encoding part, the more combinations can be generated, and the more gear positions can be formed.

[0035] When the encoding magnet 300 rotates around the circumference of the base 100, the encoding part corresponding to the sensing area of the magnetic induction assembly 210 can be switched, that is, when shifting gears, the encoding magnet 300 rotates, one encoding part leaves the sensing area of the magnetic induction assembly 210, and the adjacent other encoding part enters the sensing area of the magnetic induction assembly 210, and the first circuit board 200 outputs a corresponding signal, so each encoding part needs to be arranged in sequence along the rotation direction of the encoding magnet 300.

[0036] The encoding magnet 300 realizes the encoding effect through the arrangement combination of multiple polarities, and the magnetic induction assembly 210 makes the first circuit board 200 output a corresponding control signal according to the corresponding encoding, and the gear shifting mechanism has a compact structure and can switch a large number of gear positions.

[0037] On the basis of the above embodiment, the joystick assembly further includes a fixed rod 400 and a hollow knob 500, the base 100 is installed on the fixed rod 400, the hollow knob 500 is sleeved on the base 100 and can rotate relative to the base 100, the encoding magnet 300 is fixed in the hollow knob 500, and the hollow knob 500 drives the encoding magnet 300 to rotate around the circumference of the base 100 when rotating.

[0038] The fixing rod 400 is used to fix the base 100. The hollow knob 500 is rotatably sleeved on the base 100. Specifically, the base 100 is sleeved on the fixing rod 400 and the two are fixed together. A mounting base is fixedly provided on the fixing rod 400. The hollow knob 500 is rotatably connected to the mounting base, so the hollow knob 500 can rotate around the base 100, thereby driving the coding magnet 300 to rotate. The number of coding parts is equal to the number of rotations of the hollow knob 500. When switching gears, each rotation of the hollow knob 500 switches one coding part, that is, it drives the next coding part to move to the sensing area of ​​the magnetic induction component 210.

[0039] like Figures 1-6 As shown, based on the above embodiment, the encoding part has two magnetic regions, namely a first magnetic region 350 and a second magnetic region 360, and the magnetic induction component 210 has two Hall elements, namely a first Hall element 211 and a second Hall element 212. When the encoding part is located in the sensing area of ​​the magnetic induction component 210, the first Hall element 211 corresponds to the first magnetic region 350 and the second Hall element 212 corresponds to the second magnetic region 360.

[0040] The number of coding sections is four, namely the first coding section 310, the second coding section 320, the third coding section 330 and the fourth coding section 340. The polarity arrangement of the four coding sections is S-S, N-N, S-N and N-S.

[0041] In this embodiment, the encoding unit consists of two magnetic regions, and the magnetic induction component 210 consists of two Hall elements. The first Hall element 211 is used to correspond to and sense the first magnetic region 350, and the second Hall element 212 is used to correspond to and sense the second magnetic region 360. Since the polarity of the magnetic region can be either S or N, the four encoding units can form a total of S-S, N-N, S-N, and N-S polarity arrangements. For example, when the polarity arrangement of the encoding units is S-S, the first Hall element 211 senses the S pole, and the second Hall element 212 senses the S pole. When the gear is switched, another encoding unit moves to the sensing area of ​​the magnetic induction component 210. At this time, the polarity sensed by the first Hall element 211 and / or the second Hall element 212 changes, thus outputting a corresponding signal.

[0042] Based on the above embodiments, the coding magnet 300 has a tile-shaped structure, and the first coding part 310, the second coding part 320, the third coding part 330 and the fourth coding part 340 are arranged sequentially along the arc direction of the coding magnet 300.

[0043] On the basis of the above-mentioned embodiment, the hollow knob 500 drives the first, second, third and fourth encoding portions 310, 320, 330 and 340 to pass through the sensing area of the magnetic induction assembly 210 in sequence through the encoding magnet 300 when rotating from the starting point to the ending point of the stroke.

[0044] It should be noted that the hollow knob 500 is fixed with a tooth-shaped groove, and the base 100 is provided with an elastic member. When the hollow knob 500 rotates by one step, the next encoding portion of the encoding magnet 300 moves to the sensing area of the magnetic induction assembly 210, and the elastic member of the base 100 moves from one tooth groove to the next tooth groove, thereby generating the hand feeling during gear shifting. The rotation stroke of the hollow knob 500 is just enough to enable all the encoding portions of the encoding magnet 300 to pass through the sensing area of the magnetic induction assembly 210.

[0045] As shown in Figure 1 , Figures 4-6 On the basis of the above-mentioned embodiment, the hollow knob 500 can also move relative to the base 100. The first circuit board 200 is further provided with a third Hall element 220, and the hollow knob 500 is provided with a first magnetic element 520. Under normal circumstances, the first magnetic element 520 is offset from the third Hall element 220. When the hollow knob 500 is pressed to move, the first magnetic element 520 moves to the sensing area of the third Hall element 220.

[0046] In the present embodiment, in addition to rotating to drive the encoding magnet 300 to rotate and thereby adjust the gear position, the hollow knob 500 can also drive the first magnetic element 520 to move through its own movement, so that the hollow knob 500 has at least two gear shifting movement modes. When the hollow knob 500 is pushed, it can move along the axial direction of the base 100, so that the first magnetic element 520 approaches the third Hall element 220, thereby enabling the first circuit board 200 to output a corresponding signal.

[0047] On the basis of the above-mentioned embodiment, the hollow knob 500 is provided with a bracket 510. The bracket 510 is axially fixed with the hollow knob 500 and can rotate relative to the hollow knob 500. The bracket 510 is in sliding connection with the base 100 and is circumferentially fixed with the base 100. The first magnetic element 520 is fixed to the bracket 510.

[0048] In the embodiment, the support 510 is in the hollow knob 500 and is slidably connected with the base 100, the support 510 cannot rotate relative to the base 100, the hollow knob 500 has a stop block inside to abut against the support 510 so that the support 510 can move together with the hollow knob 500, the support 510 can drive the first magnetic element 520 to move when the support 510 moves, thereby changing the position of the first magnetic element 520, and the third Hall element 220 outputs a signal according to the position of the first magnetic element 520 (i.e. when the first magnetic element 520 moves to the sensing area of the third Hall element 220).

[0049] As shown in the above embodiment, a gear lever type gear shifter is further provided, which comprises a gear shifting mechanism based on a coded magnet, and a housing 600, and an end of the gear lever assembly is rotatably connected with the housing 600. Figures 1-8

[0050] In the above embodiment, an end of the gear lever assembly is provided with a second magnetic element 700, and the housing 600 is provided with a second circuit board 610, and the second circuit board 610 is provided with a fourth Hall element 620, which senses the position of the second magnetic element 700 and outputs a corresponding signal.

[0051] For example, when the gear lever assembly is in the middle position, the gear lever type gear shifter is in N gear, when the gear lever assembly is pushed forward or backward, it is switched to F gear or R gear, when the hollow knob 500 is rotated, it can be switched between 1 gear, 2 gear, 3 gear and D gear (i.e. one of the four coded parts is rotated to the sensing area of the magnetic sensing assembly 210), and when the hollow knob 500 is pushed to move, forced gear down can be performed (i.e. when the first magnetic element 520 moves to the sensing area of the third Hall element 220).

[0052] It should be noted that all directional indications, such as up, down, left, right, front, back, etc., are only used for explanation purposes and are not intended to be limiting.
