[0033] Figure 1 The first embodiment of the present invention provides a structural diagram of a hand-gear switch based on a linear Hall sensor. Figure 1 As shown, the arm-shift switch includes a handle 1 and a base 2. The handle 1 is movably connected to the base 2. The handle 1 is provided with a first gear switch 11 and at least one first Hall sensor 12. The first Hall sensor 12 is used to collect a first magnetic field signal generated when the first gear switch 11 is toggled, and convert the first magnetic field signal into a first voltage signal for output;

[0034] At least one second Hall sensor 21 is provided on the base 2, and the second Hall sensor 21 is used to collect a second magnetic field signal generated when the handle 1 is pushed to move, and convert the second magnetic field signal into a second voltage signal for output;

[0035] The device further includes a signal processing unit 3 for receiving the first voltage signal and the second voltage signal, and parsing the first voltage signal into a first gear signal and parsing the second voltage signal into a second gear signal.

[0036] The handle 1 is movably arranged on the base 2 , for example, the handle 1 can be pushed to move up and down or up and down on the base 2 .

[0037] The handle 1 is provided with a first gear switch 11 and at least one first Hall sensor 12. The first gear switch 11 is provided on the handle 1 in a toggleable manner, for example, the first gear switch 11 is provided on the handle 1 in a rotatable manner. When the first gear switch 11 is rotated to the corresponding gear position, it can drive the magnetic component on the handle 1 to rotate, thereby causing the magnetic field sensed by the first Hall sensor 12 to change. The first Hall sensor 12 is provided inside the handle 1 and is used to collect the first magnetic field signal generated when the position of the magnetic component corresponding to the first Hall sensor 12 changes, and output a first voltage signal corresponding to the first magnetic field signal. It should be noted that multiple first Hall sensors 12 can be provided on the handle 1, and the multiple first Hall sensors 12 can synchronously collect the first magnetic field signal generated when the position of the magnetic component changes, and the first magnetic field signal collected simultaneously by each first Hall sensor 12 corresponds to the same first gear signal.

[0038] At least one second Hall sensor 21 is provided on the base 2. The second Hall sensor 21 can be provided inside the base 2. When the handle 1 is pushed to move, the handle 1 drives the magnetic component in the base 2 to move so that the magnetic field changes, thereby generating a second magnetic field signal, and converting the second magnetic field signal into a second voltage signal output; it should be noted that multiple second Hall sensors 12 can be provided on the base 2, and the multiple second Hall sensors 12 can synchronously collect the second magnetic field signal generated when the position of the magnetic component on the base 2 changes, and the second magnetic field signal collected by each second Hall sensor 12 at the same time corresponds to the same second gear signal.

[0039] The signal processing unit 3 can be disposed on the base 2 and can be electrically connected to the first Hall sensor 12 and the second Hall sensor 21, respectively, to obtain a first voltage signal output by the first Hall sensor 12 and a second voltage signal output by the second Hall sensor 21. The signal processing unit 3 can parse the first voltage signal and the second voltage signal into a first gear position signal and a second gear position signal, thereby quickly identifying the gear shift action. The signal processing unit 3 can also transmit the gear position signal to the body controller, which adjusts the gear position based on the gear position signal.

[0040] The technical solution of the embodiment of the present utility model is to provide a first gear switch and at least one first Hall sensor on the handle for collecting a first magnetic field signal generated when the first gear switch is toggled, and to provide at least one second Hall sensor on the base for collecting a second magnetic field signal generated when the handle is pushed to move. The signal processing unit parses the first voltage signal corresponding to the first magnetic field signal into a first gear signal, and parses the second voltage signal corresponding to the second magnetic field signal into a second gear signal, thereby realizing fast and precise adjustment of the gear.

[0041] In one embodiment, if Figure 2 As shown, Figure 2 This is a schematic diagram of another embodiment of a hand-gear switch based on a linear Hall sensor provided by the present invention. Figure 2 The handle 1 is provided with two first Hall sensors 12. When the first gear switch 11 is toggled, the two first Hall sensors 12 collect two first magnetic field signals and output two first voltage signals. The two first voltage signals correspond to the same first gear signal.

[0042] Two second Hall sensors 21 are provided on the base 2. When the handle 1 is pushed to move, the two second Hall sensors 21 collect two second magnetic field signals and output two second voltage signals. The two second voltage signals correspond to the same second gear signal.

[0043] Among them, two first Hall sensors 12 are provided in the handle 1. When the first gear switch 11 is toggled, the first gear switch 11 drives the magnetic component to move, causing the magnetic field to change. At this time, both first Hall sensors 12 can collect the changed magnetic field, thereby causing the two first Hall sensors 12 to collect two first magnetic field signals and output two first voltage signals, and the two first voltage signals correspond to the same first gear signal. It should be noted that due to the different relative positions of the two first Hall sensors 12 and the magnetic component, the magnetic field signals collected by the two first Hall sensors 12 may be different. Therefore, the magnetic field signals collected simultaneously by the first Hall sensors 12 at different positions can be calibrated, that is, the gear signal corresponding to the magnetic field signal collected by the first Hall sensor 12 at the first position is the same as the gear signal corresponding to the magnetic field signal collected by the first Hall sensor 12 at the second position, so that the magnetic field signals collected simultaneously by the two first Hall sensors 12 correspond to the same first gear signal.

[0044] In a specific embodiment, the two first Hall sensors 12 can be symmetrically arranged relative to the magnetic component, or the two first Hall sensors 12 can be located on the same side of the magnetic component, and the centers of the two first Hall sensors 12 correspond to the middle position of the stroke of the magnetic component, so that the first magnetic field signals collected by the two first Hall sensors 12 are the same or similar, so that the first gear signals corresponding to the two analyzed first magnetic field signals are the same.

[0045] Two second Hall sensors 21 are provided on the base 2. When the handle 1 is pushed to move, the handle 1 drives the magnet on the base 2 to move up and down or up and down, causing the magnetic field to change. At this time, the two second Hall sensors 21 can both collect the changed magnetic field, thereby causing the two second Hall sensors 21 to collect two second magnetic field signals and output two second voltage signals. The two second voltage signals correspond to the same second gear signal. It should be noted that due to the different relative positions of the two second Hall sensors 21 and the magnetic component, the magnetic field signals collected by the two second Hall sensors 21 may be different. Therefore, the magnetic field signals collected simultaneously by the second Hall sensors 21 at different positions can be calibrated, that is, the gear signal corresponding to the magnetic field signal collected by the second Hall sensor 21 at the first position is the same as the gear signal corresponding to the magnetic field signal collected by the second Hall sensor 21 at the second position, so that the magnetic field signals collected simultaneously by the two second Hall sensors 21 correspond to the same second gear signal.

[0046] In a specific embodiment, the two second Hall sensors 21 can be arranged symmetrically relative to the magnetic component, or the two second Hall sensors 21 can be located on the same side of the magnetic component, with the centers of the two second Hall sensors 21 corresponding to the middle of the magnetic component's travel. This ensures that the second magnetic field signals collected by the two second Hall sensors 21 are identical or similar, thereby ensuring that the second gear position signals corresponding to the two analyzed second magnetic field signals are identical. Using two Hall sensors for the same gear position signal allows the signals collected by the two Hall sensors to be cross-checked, reducing the possibility of gear function failure.

[0047] In one embodiment, if Figure 3 and Figure 4 The linear Hall sensor-based shift switch shown in FIG. 1 includes a first shift switch 11 being a D / N / R shift switch, and a first shift signal including a forward shift signal, a reverse shift signal, and a neutral shift signal.

[0048] The second gear signal includes the retarder gear and the transmission upshift and downshift, the retarder gear includes retarder 1 gear, retarder 2 gear, retarder 3 gear, retarder 4 gear, retarder 5 gear, retarder 6 gear and retarder 7 gear; the transmission upshift and downshift include transmission upshift and transmission downshift.

[0049] Figure 3 The first gear switch 11 is rotatably arranged on the handle 1. The user can turn the first gear switch 11 to the D / N / R gear position. When it is turned to the D gear, the signal processing unit 3 can parse the forward gear signal; when it is turned to the N gear, the signal processing unit 3 can parse the neutral gear signal; when it is turned to the R gear, the signal processing unit 3 can parse the reverse gear signal. When the handle 1 is pushed to move forward and backward / up and down, the magnetic component of the base 2 slides along the forward and backward / up and down straight line, and each time it moves to a gear position, a changing magnetic field is generated, causing the first Hall sensor to output a corresponding voltage value, and each voltage value corresponds to a second gear signal. Specifically, as Figure 4 The seven gears of the medium retarder are used to adjust the retarder gear when the handle 1 is pushed up and down. The handle 1 can move up and down along the base to seven positions, corresponding to the seven gears, including retarder 1 gear A21, retarder 2 gear A20, retarder 3 gear A22, retarder 4 gear A23, retarder 5 gear A24, retarder 6 gear A25 and retarder 7 gear A26; when the handle 1 is pushed forward and backward, it is used to adjust the gearbox upshift and downshift. The handle 1 can move forward and backward along the base to two positions, corresponding to two gears, including gearbox upshift and gearbox downshift.

[0050] In one embodiment, the first Hall sensor 12 is located in the middle of the movement stroke of the magnet device corresponding to the first Hall sensor 12 ; the second Hall sensor 21 is located in the middle of the movement stroke of the magnet device corresponding to the second Hall sensor 21 .

[0051] It should be noted that the first Hall effect sensor 12 and the second Hall effect sensor 21 can be placed in the middle of the magnetic component's travel range. When the first Hall effect sensor 12 or the second Hall effect sensor 21 is not sensing the magnetic component or at the point where the magnetic field offsets the north and south poles, it outputs a 2.5V voltage. If the sensor is positioned too far to the left or right, the output voltage range is reduced, and the magnetic component may not be sensed. Similarly, the side of the magnetic component facing the Hall effect requires half north pole and half south pole. If only one pole faces the Hall effect, the output voltage range is halved.

[0052] In one embodiment, the handle 1 further includes at least one third Hall sensor, which is used to sense a magnetic field signal and output a low-level signal when a magnetic field signal is sensed, and generates a high-level signal when no magnetic field signal is sensed;

[0053] The signal processing unit 3 is further configured to convert the low-level signal and the high-level signal output by the third Hall sensor into a corresponding third gear position signal.

[0054] Among them, the third Hall sensor can be a switch Hall sensor, which is used to sense the magnetic field signal. When the magnetic field signal is sensed, a low level signal is output, and when the magnetic field signal is not sensed, a high level signal is generated. In a specific embodiment, the third gear signal includes A / M manual automatic gear, and the A / M manual automatic gear includes manual gear and automatic gear. When the third Hall sensor senses the magnetic field signal, a low level signal is output to switch to manual gear, and when the third Hall sensor does not sense the magnetic field signal, it switches to automatic gear. Figure 3 and Figure 4 A / M manual automatic gear position logo.

[0055] In one embodiment, the first Hall sensor 12 and the second Hall sensor 21 are linear Hall sensors; and the third Hall sensor is a switch Hall sensor.

[0056] Specifically, when the first gear switch 11 is toggled, the first gear switch 11 drives the magnetic component to move. During the movement of the magnetic component, since the first Hall sensor 12 is a linear Hall sensor, the magnetic field collected by the first Hall sensor 12 will also change linearly, and its output first voltage signal will also change linearly. When it moves to the corresponding gear position, the first Hall sensor 12 will output the first voltage signal corresponding to the current position. Different gears can correspond to different voltage values. Similarly, two second Hall sensors 21 are provided on the base 2. When the handle 1 is pushed to move, the handle 1 drives the magnet on the base 2 to move up and down or up and down. During the movement of the magnetic component, since the second Hall sensor 21 is a linear Hall sensor, the magnetic field collected by the second Hall sensor 21 will also change linearly, and its output second voltage signal will also change linearly. When it moves to the corresponding gear position, the second Hall sensor 21 will output the second voltage signal corresponding to the current position. Different gears can correspond to different voltage values.

[0057] In a specific embodiment, the circuit components inside the hand-gear switch may include a signal processing unit 3, a handle linear Hall sensor electrically connected to the signal processing unit, a base linear Hall sensor, a handle switch Hall sensor, a power module, and a LIN transceiver. Figure 5 shown.

[0058] The signal processing unit 3 is a microcontroller, specifically a single-chip microcomputer. A LIN transceiver and a power module can both be located within the base 2. The LIN transceiver transmits first, second, and third gear signals to the vehicle body controller, enabling the vehicle body controller to quickly adjust to the corresponding gear. The power module also includes a power-on detection unit and a low-dropout linear regulator unit, each electrically connected to the signal processing unit 3.

[0059] Specifically, the circuit diagram of the signal processing unit 3 is as follows: Figure 6 As shown, Figure 6 The OUT1, OUT2, OUT3, and OUT4 ports are connected to the base linear Hall sensor on the base, OUT5 and OUT6 are connected to the handle linear Hall, and OUT7 and OUT8 are connected to the handle switch Hall. Figure 7 Schematic diagram of a circuit of a power supply module, which provides a 5V voltage to the VDD port of the signal processing unit 3 . Figure 8 Schematic diagram of the circuit of the LIN transceiver. The transceiver terminals TXD and RXD of the LIN transceiver are connected to the TX port and RX port of the signal processing unit 3 respectively, and the output terminal is connected to the vehicle body controller for communication. Figure 9 There are four handle linear Hall sensors, two of which are used to collect retarder gear position signals and are connected to the OUT1 and OUT2 ports of signal processing unit 3 respectively. The other two handle linear Hall sensors are used to collect transmission gear position signals and are connected to the OUT3 and OUT4 ports of signal processing unit 3 respectively. The dual-redundancy design allows the two collected data to be cross-checked, reducing the possibility of functional failure.

[0060] The above specific embodiments do not limit the scope of protection of this utility model. Those skilled in the art will appreciate that various modifications, combinations, sub-combinations, and substitutions may be made based on design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model shall be included within the scope of protection of this utility model.
