Description

Technical Field

[0001] The utility model relates to the technical field of automotive switches, and particularly to a steering column gear shift switch for automobiles. Background Art

[0002] There are two forms of gear lever arrangements for automobiles, namely floor-mounted gear shift and steering column gear shift. When the automotive gear lever is located at the lower right of the steering wheel, it is called a steering column gear shift.

[0003] There is a prior Chinese utility model patent with the authorized announcement number CN212004204U, which discloses a steering column gear shift switch for automobiles. It includes a handle for switching gears. The gears that the handle can switch to include drive gear D, reverse gear R, neutral gear N, and home position H. The drive gear D, reverse gear R, and neutral gear N are located on the X-axis, and the neutral gear N and home position H are located on the Y-axis. When switching gears, it is necessary to first move the handle along the Y-direction from the home position to the neutral gear N on the X-axis, and then switch to the drive gear D or reverse gear R along the X-direction. The operation feedback is more obvious, the operation strategy is better, and misoperation will not occur.

[0004] However, in the above structure, when the handle moves in the gear slot, the stability is poor, and it is easy to swing at the initial position, R gear, and D gear positions. Summary of the Invention

[0005] The purpose of the utility model: In order to overcome the defects of the prior art, the utility model provides a steering column gear shift switch for automobiles, which is provided with a limiting surface corresponding to the position of the gear slot on the steering column gear shift housing to prevent the handle from swinging at the initial position, R gear, and D gear positions, and improve the acquisition of the position of the magnet by the Hall chip.

[0006] The technical solution of the utility model: A steering column gear shift switch for automobiles includes a housing, a handle, and a rotating bracket. The rotating bracket is rotatably connected to the housing, and the handle is rotatably connected to the rotating bracket. The housing is integrally provided with or fixedly connected to a gear seat. The gear seat is provided with a first gear slot arranged along the Y-axis and a second gear slot arranged along the X-axis. The first gear slot and the second gear slot are arranged in an inverted T shape. The two ends of the second gear slot respectively correspond to the drive gear D or reverse gear R. The intersection position of the first gear slot and the second gear slot is the neutral gear N. The upper end of the first gear slot is the home position H. The housing is provided with a first limiting surface and a second limiting surface. The first limiting surface corresponds to the position of the first gear slot, and the second limiting surface corresponds to the two ends of the second gear slot. The handle is provided with an extension piece. When the handle is located in the first gear slot, the extension piece is in contact with the first limiting surface. When the handle is located in the drive gear D or reverse gear R, the extension piece is in contact with the corresponding second limiting surface.

[0007] With the above technical solution, the initial position H and the neutral position N are on the same straight line on the Y-axis, and the neutral position N, the forward gear D, and the reverse gear R are on the same straight line on the X-axis. When the handle is in the initial position H, lift the handle to the neutral position N, and then operate the handle to move forward and backward to make it enter the forward gear D or the reverse gear R. The neutral position N can prevent misoperation. At the same time, the cooperation between the limiting surface and the extension piece prevents the handle from swinging at the initial position, the forward gear D, and the reverse gear R positions, and can also improve signal acquisition.

[0008] A further setting of the present utility model: Two limiting seats are further provided on the outer shell along the X-axis direction. The two limiting seats are spaced apart to form an activity space. The rotating bracket is located in the activity space. Third limiting surfaces are provided on the opposite side walls of the two limiting seats, and corresponding fourth limiting surfaces are provided on the rotating bracket. The third limiting surface and the fourth limiting surface cooperate to limit the rotation angle of the rotating bracket.

[0009] With the above further setting, when the handle performs a gear shifting operation, it can prevent the handle from overshifting.

[0010] A further further setting of the present utility model: A circuit board is provided inside the outer shell. Positioning grooves are opened on the inner side wall of the outer shell along its vertical direction. Both ends of the circuit board are located in the corresponding positioning grooves. A Hall switch is provided on the circuit board, and a magnet is correspondingly provided on the handle.

[0011] With the above further further setting, the vertical setting of the circuit board reduces the space requirement. The cooperation with the positioning pins makes the structure of the circuit board stable and the installation convenient. The circuit board is provided with pins for connecting to an external circuit. The pins and the circuit board are welded by perforation. The magnet moves under the drive of the handle, and the distance and position between the magnet and the Hall switch change, causing the Hall switch to generate a potential difference. The potential difference can be converted into an angle value of the handle to control the gear shift.

[0012] A further further setting of the present utility model: Grooves with a concave cross-section are opened on the circuit board corresponding to the positions of the first gear slot and the second gear slot. The end of the handle passes through the grooves and moves in the gear slots.

[0013] With the above further further setting, it is convenient for the handle to move, makes the handle move more smoothly, and does not affect the cooperation between the magnet and the Hall switch at the same time.

[0014] A further further setting of the present utility model: It further includes a gear shift pin and a spring. A receiving groove is provided on the handle. The gear shift pin and the spring are located in the receiving groove. An installation groove is opened on the gear shift pin. One end of the spring is located in the installation groove, and the other end abuts against the bottom wall of the receiving groove.

[0015] With the above further setting, the end of the gear position pin is spherical, which makes the sliding in the gear position groove smoother. When the handle moves in the gear position groove, the gear position pin will slide in the accommodating groove and press against the spring. After the handle moves, the spring is used to apply a thrust force that pushes the gear position pin towards the gear position seat, so that the gear position pin remains in contact with the gear position seat.

[0016] A further setting of the present utility model: guiding ribs are provided on both side walls of the gear position pin, and guiding chutes are provided on both sides of the handle located in the accommodating groove, and the guiding ribs are slidably arranged in the corresponding guiding chutes.

[0017] With the above further setting, it can play a guiding role, making the structure more stable when the gear position pin slides in the handle.

[0018] A further setting of the present utility model: the housing includes a separately arranged upper cover, a middle seat and a base. The two limit seats and the gear position seat are all arranged on the middle seat. A first through hole is opened in the limit seat along its vertical direction, a threaded hole is correspondingly provided on the base, and a second through hole is correspondingly provided on the upper cover. The end of the fastener sequentially passes through the second through hole, the first through hole and is matched with the threaded hole.

[0019] With the above further setting, the separate setting is convenient for the installation of each internal component. Not only is it connected by fasteners, but the upper cover and the middle seat, as well as the middle seat and the base, are also connected by buckles, making the structure firmer and more stable.

A rotating shaft 31 is provided on the rotating bracket 3 along its vertical direction, and a rotating hole 11 is provided on the housing 1. The rotating shaft 31 is rotatably disposed in the rotating hole 11. A first mounting hole 32 is formed on the rotating bracket 3, and a second mounting hole 21 is formed on the handle 2 along the X-axis direction. When the rotating bracket 3 is sleeved outside the handle 2, the two mounting holes are coaxially arranged. A rotating shaft or a pin can be provided in the two mounting holes so that the handle 2 can rotate relative to the rotating bracket 3 around the X-axis. An integral or fixedly connected gear position seat 12 is provided on the housing 1. A first gear position groove 121 arranged along the Y-axis and a second gear position groove 122 arranged along the X-axis are provided on the gear position seat 12. The first gear position groove 121 and the second gear position groove 122 are arranged in an inverted T shape. The two ends of the second gear position groove 122 respectively correspond to the forward gear D or the reverse gear R. The intersection position of the first gear position groove 121 and the second gear position groove 122 is the neutral gear N. The upper end of the first gear position groove 121 is the original position H. A first limiting surface 13 and a second limiting surface 14 are provided on the housing 1. The first limiting surface 13 corresponds to the position of the first gear position groove 121, and the second limiting surface 14 corresponds to the two ends of the second gear position groove 122. An extension piece 22 is provided on the handle 2. When the handle 2 is located in the first gear position groove 121, the extension piece 22 abuts against the first limiting surface 13. When the handle 2 is located in the forward gear D or the reverse gear R, the extension piece 22 abuts against the corresponding second limiting surface 14. The original position H and the neutral gear N are on the same straight line in the Y-axis direction, and the neutral gear N, the forward gear D, and the reverse gear R are on the same straight line in the X-axis direction. When the handle 2 is located at the original position H, lift the handle 2 to make it located at the neutral gear N, and then operate the handle 2 to move forward and backward to make it enter the forward gear D or the reverse gear R. The neutral gear N can prevent misoperation, and at the same time, the cooperation between the limiting surface and the extension piece 22 prevents the handle 2 from swinging at the original position, the forward gear D, and the reverse gear R positions. A circuit board 4 is provided inside the housing 1. A positioning groove 15 is formed on the inner side wall of the housing 1 along its vertical direction. Both ends of the circuit board 4 are respectively located in the corresponding positioning grooves 15. A Hall switch 41 is provided on the circuit board 4. A magnet 23 is correspondingly provided on the handle 2. An extension block 26 is provided on the handle 2. A receiving cavity with an opening on one side is formed on the extension block 26. An opening for the magnet 23 to be exposed is provided on the side of the extension block 26 facing the circuit board 4. The vertical setting of the circuit board 4 reduces the space requirement, and the combination with the positioning pin groove makes the structure of the circuit board 4 stable and the installation convenient. Plug pins 42 for connecting with an external circuit are provided on the circuit board 4. The plug pins 42 and the circuit board 4 are welded by perforation. The magnet 23 moves under the drive of the handle 2, and the distance and position between the magnet 23 and the Hall switch 41 change, so that the Hall switch 41 generates a potential difference. The potential difference can be converted into an angular value of the handle 2 to control the gear shift, and at the same time, the signal acquisition can also be improved.A slot 43 with a concave cross-section is provided on the circuit board 4 corresponding to the positions of the first gear slot 121 and the second gear slot 122. The end of the handle 2 passes through the slot 43 and moves within the gear slot, facilitating the movement of the handle 2, making the movement of the handle 2 smoother, and at the same time not affecting the cooperation between the magnet 23 and the Hall switch 41.
