Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive parts technology and relates to a non-contact shift controller. Background Technology
[0002] Currently, the gear shift controller and its actuator are the core components of automotive gear shifting. Traditional solutions include a gear shift controller control board and a gear shift controller actuator. When the gear shift motor is working, it drives the motor shaft to rotate in both directions, thereby pushing the gear shift lever to reciprocate, which in turn drives the connecting rod to move. The connecting rod head drives the internal rotation of an external position sensor, and the external position sensor outputs a voltage signal to indicate the change in the lever position. The existing structure has the problems of a large number of parts, large space occupation, and high cost. At the same time, it has the problem of low reliability due to the transmission of signals through long-distance wiring harnesses. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a non-contact shift controller. By integrating the shift control board onto the actuator, a separate position sensor is eliminated. This controller features a simple and reasonable structure, reduced assembly space, and improved shift reliability.
[0004] The technical solution adopted by this utility model is as follows: a non-contact shift controller, a shift motor and a shift housing, the shift motor is connected to the shift housing by bolts, the motor shaft of the shift motor passes horizontally through the shift housing; the shift lever is fitted onto the motor shaft and reciprocates along the motor shaft inside the shift housing; the shift lever is rotatably connected to one end of a swing linkage, the other end of the swing linkage passes through the shift housing, and a magnet is installed at the end of the swing linkage; the shift control board is installed on the side wall of the shift housing through an outer mounting shell, and the magnetic encoding chip on the shift control board is concentrically arranged with the magnet.
[0005] Furthermore, the distance between the magnet and the magnetically encoded chip is 2–5 mm.
[0006] Furthermore, the magnet is circular in shape, with the upper and lower half-planes of the circular magnet being the N and S poles, respectively.
[0007] Furthermore, the mounting screws on the outer mounting housing pass through the shift control plate and connect to the shift housing.
[0008] Furthermore, the swing angle of the swing linkage is -45° to 45°.
[0009] Furthermore, the positive and negative wires of the shift motor are soldered to the shift control board, and the shift motor receives electrical signals from the shift control board to perform forward and reverse rotation.
[0010] Furthermore, the guide shaft is fixed to the inner wall of the shift housing by bolts at one end, and passes through the shift lever at the other end.
[0011] The beneficial effects of this utility model are:
[0012] 1. By integrating the shift control board onto the actuator, a separate position sensor and position sensor connection harness are eliminated, optimizing the assembly space.
[0013] 2. By setting a magnet at the end of the connecting rod, the magnet does not contact the magnetic encoding chip. The magnetic field changes to make the magnetic encoding chip output the corresponding position information. This method is stable and reliable.
[0014] 3. It avoids the accuracy loss of signals transmitted over long distances, reduces the number of parts, lowers production costs, and increases efficiency. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0021] like Figures 1-4 As shown, a non-contact gear shift controller includes a gear shift motor 1 and a gear shift housing 10. The gear shift motor 1 is connected to the gear shift housing 10 by bolts, and the motor shaft 2 of the gear shift motor 1 horizontally passes through the gear shift housing 10. The gear shift lever 3 is fitted onto the motor shaft 2 and reciprocates along the motor shaft 2 inside the gear shift housing 10. The gear shift lever 3 is rotatably connected to one end of a swing linkage 4, and the other end of the swing linkage 4 passes through the gear shift housing 10. A magnet 6 is installed at the end of the swing linkage 4. The gear shift control board 9 is installed on the side wall of the gear shift housing 10 through an outer mounting shell 8, and the magnetic encoding chip 7 on the gear shift control board 9 is arranged concentrically with the magnet 6.
[0022] The distance between magnet 6 and magnetic encoding chip 7 is 2–5 mm. Within this range, sampling accuracy is high, and there will be no sampling error caused by the sparse linear density of the magnetic field.
[0023] Magnet 6 is perfectly circular, with the upper and lower halves of its surface serving as the N and S poles, respectively. This structure allows for better control of magnetic field variations, ensuring stable and accurate signal transmission.
[0024] The mounting screws on the outer mounting shell 8 pass through the shift control plate 9 and connect to the shift housing 10.
[0025] The swing angle of the swing link 4 is -45° to 45°. This is to avoid the situation where the magnetic encoding chip 7 receives a single magnetic field signal due to excessive rotation angle.
[0026] The positive and negative wires of the shift motor 1 are soldered to the shift control board 9. The shift motor 1 receives electrical signals from the shift control board 9 to perform forward and reverse rotation.
[0027] It also includes a guide shaft 5, one end of which is fixed to the inner wall of the shift housing 10 by a bolt, and the other end passes through the shift lever 3 to guide the reciprocating motion of the shift lever 3.
[0028] The working process of this device is as follows:
[0029] 1. The shift control board 9 sends an electrical signal to the shift motor 1, and the shift motor 1 receives the electrical signal and rotates in the forward and reverse directions;
[0030] 2. The motor shaft 2 drives the shift lever 3 to reciprocate, causing the swing link 4 to swing at a specific angle;
[0031] 3. The swing linkage 4 swings at a specific angle, causing the magnet to rotate;
[0032] 4. The magnetic field signal changes;
[0033] 5. The magnetic encoding chip outputs the corresponding position information based on the magnetic field.
[0034] The advantages of this device are:
[0035] 1. By integrating the shift control board onto the actuator, a separate position sensor and position sensor connection harness are eliminated, optimizing the assembly space.
[0036] 2. By setting a magnet at the end of the connecting rod, the magnet does not contact the magnetic encoding chip. The magnetic field changes to make the magnetic encoding chip output the corresponding position information. This method is stable and reliable.
[0037] 3. It avoids the accuracy loss of signals transmitted over long distances, reduces the number of parts, lowers production costs, and increases efficiency.
