Description

Technical Field

[0001] The utility model belongs to a vehicle shift type combined switch, which is a new structure of a combined switch integrating a new shift function, specifically a Hall type shift knob switch. Background Technique

[0002] In recent years, with the development of maximizing the space of the vehicle cab, the shift switch has gradually moved from the auxiliary console to the right handle of the combined switch. This kind of shift switch is convenient to operate, and the driver can shift gears without leaving the steering wheel with both hands. For the switch integrating the shift function inside the right handle of the combined switch, due to its frequent use and the required durability of up to 400,000 times, the traditional mechanical contacts cannot meet the requirements. Therefore, a non-contact Hall switch is adopted. Through the annular arrangement of three Hall switches, different arrangement methods are used to connect and disconnect, so as to realize the signal acquisition of the three gears of "neutral gear, forward gear, and reverse gear", and then realize the actions of the three gears. Summary of the Invention

[0003] The purpose of the utility model is to provide a Hall type shift knob switch with a simple structure and convenient operation, which solves the problems that the rotation angle of the Hall type shift knob switch is small, meeting the requirements of ergonomics, and the Hall switches will not malfunction due to the small distance between the Hall switches and being interfered by electromagnetic signals.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme: a Hall type shift knob switch, including a wire harness, a lower fixed seat, and an upper fixed seat. The wire harness is electrically connected to the corresponding Hall switch on the PCB board through the central hole of the lower fixed seat. A plurality of Hall switches are fixedly connected to the PCB board, and the inner hole of the PCB board is inserted on the outer wall of the central hole of the lower fixed seat. The outer end face of the PCB board corresponds to the end face of a multi-stage magnetic ring with a small gap. There are a plurality of magnetic poles on the multi-stage magnetic ring, and the inner hole of the multi-stage magnetic ring is clamped on the outer wall of the central hole at one end of a knob. The inner hole end face at the other end of the knob contacts the outer circular end face of an upper fixed seat. One end of the upper fixed seat passes through the central hole of the knob and is clamped and fixed to the outer wall of the central hole of the lower fixed seat. The middle part of the upper fixed seat is inserted into the knob and forms a knob switch with the knob through a plurality of switch elements.

[0005] Further, the multi-stage magnetic ring is a two-stage magnetic ring, and the two magnetic poles are evenly distributed on the multi-stage magnetic ring at 180°.

[0006] Further, three evenly distributed Hall switches are fixedly connected to the PCB board, and the included angle between the neutral gear Hall switch and the forward gear Hall switch and the reverse gear Hall switch is 150° respectively.

[0007] Further, when the position of the neutral Hall switch on the PCB board coincides with the position of one magnetic pole of the multi-stage magnetic ring, the positions of the other magnetic poles of the multi-stage magnetic ring form an angle of 30° with the positions of both the forward gear Hall switch and the reverse gear Hall switch.

[0008] Further, the central axes of the lower fixing base, the PCB board, the multi-stage magnetic ring, the knob, and the upper fixing base all coincide.

[0009] Further, the knob switch formed by the upper fixing base and the knob can achieve the actions of three gears by rotating the angle of the knob.

[0010] The beneficial effects of the present utility model: Compared with the prior art, the present utility model provides a Hall-type shift knob switch with a simple structure and convenient operation, which solves the problems that the rotation angle of the knob of the Hall-type shift knob switch is small, meets the requirements of ergonomics, and will not cause misoperation due to the small distance between Hall switches and the interference of electromagnetic signals on the Hall switches.

[0018] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the drawings.

[0019] AsFigures 1 to 6 As shown in the figure, a Hall type shift knob switch includes a wire harness 1, a lower fixed seat 2, and an upper fixed seat 9. The wire harness 1 is electrically connected to the corresponding Hall switch on the PCB board 3 through the central hole of the lower fixed seat 2. A plurality of Hall switches are fixedly connected to the PCB board 3, and the inner hole of the PCB board 3 is inserted into the outer circular wall of the central hole of the lower fixed seat 2. The outer end face of the PCB board 3 corresponds to the end face of a multi-stage magnetic ring 7 with a small gap. There are a plurality of magnetic poles 10 on the multi-stage magnetic ring 7, and the inner hole of the multi-stage magnetic ring 7 is clamped on the outer circular wall of the central hole at one end of a knob 8. The inner hole end face at the other end of the knob 8 contacts the outer circular end face of an upper fixed seat 9. One end of the upper fixed seat 9 passes through the central hole of the knob 8 and is clamped and fixed to the outer circular wall of the central hole of the lower fixed seat 2. The middle part of the upper fixed seat 9 is inserted into the knob 8 and forms a knob switch with the knob 8 through a plurality of switching elements.

[0020] In this embodiment, without changing the rotation angle of the knob of the original Hall type shift knob switch, the distance between the Hall switches can be effectively increased, avoiding misoperation of the Hall switches due to electromagnetic signal interference.

[0021] As Figure 1 shown, the multi-stage magnetic ring 7 is a two-stage magnetic ring, and the two magnetic poles 10 are evenly distributed on the multi-stage magnetic ring 7 at 180° to each other.

[0022] In this embodiment, the multi-stage magnetic ring 7 can be five-pole or two-pole, and both can achieve the same effect. However, a two-stage magnetic ring is preferably used, and the two magnetic poles 10 are evenly distributed on the multi-stage magnetic ring 7 at 180° to each other.

[0023] As Figure 1 shown, three evenly distributed Hall switches are fixedly connected to the PCB board 3. The angle between the neutral gear Hall switch 6 and the forward gear Hall switch 4 and the reverse gear Hall switch 5 is 150° each.

[0024] In this embodiment, the angle between the three Hall switches fixedly connected to the PCB board 3 is greater than 60°, which is twice as large as the 30° angle between the Hall switches in the prior art. It can effectively avoid the small distance between the Hall switches, preventing the Hall switches from being interfered by electromagnetic signals and misoperating.

[0025] As Figure 5 shown, when the position of the neutral gear Hall switch 6 on the PCB board 3 coincides with the position of a magnetic pole 10 of the multi-stage magnetic ring 7, the angle between the position of the other magnetic pole 10 of the multi-stage magnetic ring 7 and the positions of the forward gear Hall switch 4 and the reverse gear Hall switch 5 is 30° each.

[0026] What is shown in this embodiment is a schematic diagram of the position structure of the neutral gear Hall switch of the Hall type shift knob switch. The schematic diagram of the position structure of the forward gear Hall switch of the Hall type shift knob switch is asFigure 4 As shown, the schematic structural diagram of the reverse gear Hall switch position of the Hall-type shift knob switch is as Figure 6 shown.

[0027] As Figure 1 shown, the central axes of the lower fixing seat 2, the PCB board 3, the multi-stage magnetic ring 7, the knob 8, and the upper fixing seat 9 all coincide;

[0028] In this implementation, when the central axes coincide, it is convenient to accurately assemble the Hall-type shift knob switch into a switch assembly.

[0029] As Figures 1 to 2 shown, the knob switch formed by the upper fixing seat 9 and the knob 8 can achieve the actions of three gears by rotating the knob 8 by an angle;

[0030] In this implementation, the forward gear, neutral gear, and reverse gear are arranged in sequence, with the neutral gear in the middle. When the knob 8 is in the neutral gear position, if it rotates 30° to one side to reach the forward gear position, then rotating 30° to the other side of the neutral gear is the reverse gear position.

[0031] In addition, the knob switch with three gears formed by the upper fixing seat 9 and the knob 8 described in the present utility model is all mature prior art and common general knowledge, and the present utility model will not be explained in detail.

[0032] The specific working principle of the present utility model:

[0033] First, the knob 8 of a Hall-type shift knob switch of the present utility model is normally in the neutral gear position. At this position, when the position of the neutral gear Hall switch 6 on the PCB board 3 coincides with the position of a magnetic pole 10 of the multi-stage magnetic ring 7, the position of the other magnetic pole 10 of the multi-stage magnetic ring 7 forms an angle of 30° with the positions of the forward gear Hall switch 4 and the reverse gear Hall switch 5. The magnetic field of the magnetic pole 10 turns on the neutral gear Hall switch 6 in the coincident position, conducting the neutral gear action of the vehicle;

[0034] Then, when the vehicle needs to move forward, rotate the knob 8 30° from the neutral gear position to one side. The position of the forward gear Hall switch 4 on the PCB board 3 coincides with the position of a magnetic pole 10 of the multi-stage magnetic ring 7, and the neutral gear Hall switch 6 and the reverse gear Hall switch 5 are out of the magnetic field effect area of the other magnetic pole 10. At this time, the magnetic field of the magnetic pole 10 turns on the forward gear Hall switch 4 in the coincident position, conducting the forward gear action of the vehicle;

[0035] Finally, when the vehicle needs to reverse, rotate the knob 8 30° to the other side from the neutral position. The position of the reverse Hall switch 5 on the PCB board 3 coincides with the position of a magnetic pole 10 of the multi-stage magnetic ring 7, and the neutral Hall switch 6 and the forward gear Hall switch 4 are disengaged from the magnetic field effect area of the other magnetic pole 10. At this time, the magnetic field of the magnetic pole 10 turns on the reverse Hall switch 5 with the coincident position, conducting the reverse gear operation of the vehicle.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any simple modifications, equivalent replacements, improvements, etc. made within the technical concept of the present invention shall be included within the protection scope of the present invention.
