Description

Technical Field

[0001] This utility model relates to the field of column shifter switch technology, and in particular to a column shifter switch with lateral gear transmission. Background Technology

[0002] There are two types of gear shift levers in automobiles: floor shift and column shift. The gear shift lever located to the lower right of the steering wheel is called a column shift.

[0003] Current automotive column shifters include a handle and a housing. The housing contains a first circuit board, a shift block, and a transmission gear. A Hall effect switch is mounted on the first circuit board. A shift pin is mounted on the handle, sliding along with the handle on the shift block. The transmission gear includes a primary gear and a secondary gear. The handle drives the primary gear, which in turn moves the secondary gear. A magnet is mounted on the secondary gear. Because the transmission gears in these column shifters are typically stacked vertically, the switch body is relatively thick, requiring significant space in the Z-axis direction. Summary of the Invention

[0004] The purpose of this utility model is to overcome the defects of the prior art by providing a side gear transmission shift switch, which integrates the main gear structure into the side of the handle end, reduces the Z-axis spatial layout of the switch, and reduces the development and assembly of parts.

[0005] The technical solution of this utility model is as follows: A side-gear driven shift switch includes a handle and a housing. The housing contains a first circuit board, a shift block, and a gear. The first circuit board has a Hall switch, and the gear contains a magnet that rotates synchronously with it. The handle has a shift pin that is movably disposed within the shift block. The handle has an integrally formed rotating part that extends into the housing and rotates in cooperation with it. The rotating part has a mounting cavity, and the shift pin is installed in the mounting cavity. The shift pin rotates synchronously with the rotating part and slides axially with the rotating part. The side of the rotating part has an extension block, and the side of the extension block has a serrated structure that meshes with the gear. The first circuit board is located in front of the gear and the extension block.

[0006] By adopting the above technical solution, the handle is pushed up and down, and the handle rotates, which drives the gear and the magnet to rotate synchronously. The magnet rotates relative to the Hall switch, so that the Hall switch can collect functional signals and realize functional output. The gear is set on the side of the rotating part, and the sawtooth structure is integrated on the rotating part, which makes the transmission between the handle and the gear more stable. At the same time, it also reduces the number of switch parts, making the overall structure simpler, compressing the Z-axis space of the shift switch, and reducing the overall weight of the shift switch.

[0007] A further feature of this invention is that the housing has a pin hole, the rotating part has a pin, the end of the pin is inserted into the pin hole, and the rotating part rotates along the pin shaft to drive the stop pin and gear to move.

[0008] The above-mentioned further design facilitates the rotation of the handle relative to the housing while preventing the handle from detaching from the housing, resulting in a simple installation structure.

[0009] A further feature of this invention is as follows: the housing is provided with a first receiving cavity and a second receiving cavity. The first receiving cavity is open on the side facing the rotating part. The inner sidewall of the first receiving cavity is provided with a plurality of positioning grooves. The outer sidewall of the stop block is provided with a plurality of positioning protrusions. The positioning protrusions are inserted into the corresponding positioning grooves. The gear part is rotatably disposed in the second receiving cavity, and the part that meshes with the sawtooth structure is exposed outside the second receiving cavity. The housing is provided with a plurality of fixing posts, which are inserted into the first circuit board.

[0010] The above-mentioned further design ensures that the internal structures of the housing are stable, robust, and not easily moved, thus avoiding disruption to operation. At the same time, the installation structure is simple and the operation is convenient.

[0011] A further feature of this invention is that the gear has a fixed cavity, the magnet is located inside the fixed cavity, the fixed cavity has a slot on the side near the first circuit board for the magnet to be exposed, and a number of positioning plates are provided on the side wall of the other side of the fixed cavity.

[0012] The above-mentioned further design makes the magnet structure secure and prevents it from detaching from the gear, while also making it easy to install into the gear.

[0013] A further feature of this invention is that the inner wall of the mounting cavity is provided with several guide protrusions, and the outer wall of the stop pin is provided with several guide grooves. The guide protrusions are located in the guide grooves to achieve synchronous rotation and axial sliding cooperation between the stop pin and the rotating part.

[0014] The above-mentioned further design serves as a guide, ensuring structural stability when the shift pin slides relative to the rotating part, while the rotation of the rotating part can drive the shift pin to rotate synchronously.

[0015] A further feature of this invention is that the stop pin has a recessed cavity along its sliding direction, a spring is provided in the recessed cavity, a connecting post is provided in the mounting cavity, one end of the spring abuts against the bottom wall of the recessed cavity, and the other end is sleeved on the connecting post, the end of the stop pin near the stop block is arc-shaped, and the stop block has a stop track.

[0016] With the above-mentioned further configuration, the gear position pin moves along the gear position trajectory under the action of the handle and slides into the mounting cavity. It is then reset by a spring. The spring structure is stable and better drives the gear position pin to slide out of the mounting cavity.

[0017] A further feature of this invention is that a P-position button is movably provided at the end of the handle away from the housing. The handle contains a fixed frame and a second circuit board fixed on the fixed frame. The second circuit board is electrically connected to the first circuit board. The second circuit board is provided with an LED light and a micro switch. The P-position button is slidably disposed on the fixed frame, and a reset element for resetting the P-position button outward from the handle is provided between the button and the micro switch.

[0018] With the above-mentioned further design, the reset component uses a return rubber setting. Pressing the P-gear button into the handle triggers the micro switch. After releasing the button, the reset component resets the button, realizing parking, and the LED light illuminates, allowing the driver to more intuitively perceive that the vehicle is in a parked state, making it safer.

[0019] A further feature of this invention is that the fixing frame is provided with an exciter, which is located on one side of the second circuit board and connected to the second circuit board.

[0020] With the above-mentioned further settings, vibration feedback can be added to allow the driver to more intuitively perceive the vehicle's gear shift and prevent accidental operation. Specifically, when the column shifter is switched to R gear, the exciter will vibrate. Attached Figure Description
